By means of the foaming ruminal tympany deflation puncture device, deflation rhythm can be controlled through an electromagnetic push-press box, air pressure in the rumen can be monitored through a pressure sensor, working intensity of operation staff is reduced, meanwhile, deflation rhythm and speed can be automatically controlled, and insertion depth of a needle body can be preset.
Description
Technical field
The present invention relates to the technical field of veterinary medicine apparatus, particularly relate to spumescence ruminal tympany venting sting device.
Background technology
Ruminal tympany is the distinctive a kind of digestive system disease of ruminant, can be divided into acute ruminal tympany and chronic ruminal tympany by the course of disease.Because chronic ruminal tympany is not independently disease, but a kind of syndrome seen in esophagus, glandular stomach, abomasum and intestinal chronic disease process, Therapeutic Principle is mainly to remove protopathy, and symptomatic treatment is to no effect many, so ruminal tympany typically refers to acute ruminal tympany.
Acute ruminal tympany is that contractility weakens, and the easy fermented feed of searching for food is rapid zymolysis under flora effect in cud, produces a large amount of gas (foam) because glandular stomach nerves reaction reduces, and the cud caused and reticulum sharply tympanites.According to characteristic of disease, acute ruminal tympany can also be further divided into spumescence distension gas and gaseousness distension gas.Acute ruminal tympany is mainly in cattle and sheep, and goat is rare.Sickness rate in south China farm cattle, accounts for the 15%-20% of fore stomach disease.The cattle and sheep of summer pasturing may occur in groups, and case fatality rate can reach 30%, and the cattle and sheep of drylot feeding, as miscarriage, also can be mass-sended, and mortality rate is also higher.
Cud is just as fermentation tank, and the gas that the forage grass searched for food, feedstuff produce in its zymolysis and transporting process, mainly carbon dioxide and methane, also has a small amount of hydrogen, oxygen, nitrogen and sulfur etc.These gases, except part is formed except gas cap on content surface, discharge with belch by ruminating mostly, or in company with rumen content running the most pure virginity harmonization of the stomach intestinal absorption, thus keep the relative equilibrium of aerogenesis and aerofluxus.But under pathological state, the easy fermented feed of searching for food, produces a large amount of gas, can not be discharged by belch, in company with content by gastrointestinal absorption and eliminating, can not thus cause cud acute dilatation and distension gas again.
The mechanism of spumescence ruminal tympany is comparatively complicated.The formation of foam, depends mainly on these three kinds of colloid chemical factors of absorption property of the surface tension of rumen fluid, viscosity and foam surface.The feedstuff of easy fermentation, particularly leguminous plant, containing the material such as protein, saponin, pectin of volume, can produce bubble.Wherein ribosome (rRNA) 18S has more the characteristic of foam generated.Mucin in pectin, saliva and the polysaccharide of antibacterial can increase the viscosity of rumen fluid.The organic acid produced in rumen content sweat, heat is not the non-volatile acids such as citric acid, malonic acid, succinic acid, and the pH of rumen fluid can be made to decline.When pH is down to 6.0-5.2, the stability of foam is higher, can not overflow, so that blocks cardia, and belch stops, and within the short time, develop into foam type distension gas.The generation of gaseousness ruminal tympany, mainly result from institute's cyanogentic glycoside and dehydrogenation progesterone compound (similar Citrin) in a large amount of free carbon dioxide and methane and feedstuff that cud intracellular bicarbonate salt, sweat produce, reduce front neurogastric irritability, and have inhibitory action to cud contraction.
In the PD of ruminal tympany, due to cud wall overdistension, intra-abdominal pressure raises, and intrathoracic negative pressure reduces, and makes breathing and blood circulation generation obstacle.Corrupt in cud, zymolysis product stimulates cud wall generation spasmodic contraction, and is the uneasy phenomenon of pain.Disease latter stage, cud wall tension force completely loses, and gas is discharged more difficult, and in blood, carbon dioxide significantly raises, and alkali storage declines, visible venous engorgement, dyspnea, suffocates with cardioplegia and death within a few hours.
The Therapeutic Principle of ruminal tympany is aerofluxus relieving distension, and only ferment of regulating the flow of vital energy, heart tonifying is infused, stomach invigorating food stagnation removing.In therapeutic process, the general cud puncture needle that uses is to cud puncture venting, takes orally simultaneously or stops ferment food stagnation removing medicine partner treatment by canula puncture needle to tumor intragastric infusion.But in the cud puncture deflation course of reality, there is inconvenience in traditional cud puncture needle, below for cattle, illustrates one by one.First, for foam type distension disorder of QI cattle, after the capable cud puncture of puncture needle, due to the existence of chyme on a large amount of bubble and bubble, gas vent must block, and can only discharge a small amount of gas by spells, if extract puncture needle cleaning again carry out puncture venting, effect of not only exitting is still undesirable, also can increase disease cattle pain and infection risk on foot, second, for the ruminal tympany due to esophagus disease secondary such as esophageall obstruetion, spasm and paralysis, and the situation of spumescence distension vapour lock plug cardia, only ferment food stagnation removing medicine cannot oral or gavage, can only be poured into by cud paracentesis trocar, which results in puncture venting and pour into food stagnation removing medicine and can not carry out simultaneously, the therapeutic time of acute distension disorder of QI cattle can be incured loss through delay, also can affect rescued effect, 3rd, even if for simple gaseousness ruminal tympany, general sick cattle can not coordinate oral or conduit gavage medicine, still need by puncture needle perfusion only ferment food stagnation removing medicine, and traditional puncture needle only have a pin hole (i.e. air vent) can for perfusion, not only rate of flooding is slow, and owing to being single-point perfusion, only ferment food stagnation removing or stomach invigorating medicine can only work (when there is ruminal tympany at very large cud one place, cud wall is tight, smooth muscle automatic mobility weaken, rumen content operational delay), effectively cannot play only ferment food stagnation removing effect, also stomach invigorating medicine cannot be made to play one's part to the full, 4th, the especially acute ruminal tympany of ruminal tympany should effectively control venting speed when puncturing venting, carry out batch (-type) venting, in order to avoid after Rapid degassing, abdominal pressure reduces rapidly, and intrathoracic negative pressure raises, and blood refluxes rapidly, cause cerebral anoxia, and traditional puncture needle there is no the device that can control intermittent venting, 5th, puncture needle insertion depth is uncontrollable.
Application number is that the device of the patent disclosed treatment ruminal tympany of 201420327559.0 has venting portion and injection portion, solve venting and the problem that can not simultaneously carry out of dabbling drug, but, though its technical scheme has set up several air vent in venting portion, also the gas of multiple bubble just can be got rid of for spumescence ruminal tympany, still easily blocked by the chyme in bubble, its practical application effect is also bad; In addition, its injection portion is the same with traditional puncture needle, can only carry out single-point injection at syringe needle, and ruminant tumor gastric (especially cattle) bulky, and during distension gas, Kuminal motility is sluggish, single-point injectable drug poor effect, generation drug effect is slow, causes therapeutic effect undesirable.

Compared with prior art, puncture venting pin of the present invention, because have venting portion and injection portion simultaneously, can exitted while cud perfusion only ferment food stagnation removing or heart tonifying stomach invigorating medicine; Meanwhile, due to the existence of adjustable pipe and flexure strip, make puncture venting pin air vent when entering cud can not block by the chyme on foam; In addition, injection portion can launch in ruminant tumor gastric, rotate injection, and can Non-follow control injection portion velocity of rotation, while machinery hits froth breaking, by dabbling drug multiple spot, impose in cud on a large scale, in all directions, make to exit, the effect of froth breaking and drug infusion promotes all greatly; Further, venting portion is provided with pressure sensor (baroreceptor), can monitor cud internal gas pressure at any time, to instruct rhythm and the speed of intermittent venting; Finally, The invention also achieves the rhythm and time that automatically control intermittent venting, greatly facilitate surgical staff.The flexible pipe that injection portion has upper, middle and lower three support columns and is fixed on inside support column, this combinative structure designs to coordinate injection portion physics to smash bubble in cud: only use flexible pipe injection, flexible pipe cannot rotate broken bubble because of the flexibility of itself in cattle abdomen, only cannot ensure by the sealing of hard tube then each articulare of injection portion.The present invention then efficiently solves this problem: medicinal liquid only flows in flexible pipe, and good airproof performance, can not leak medicine, and rigid support structure is fixed on flexible pipe periphery, for flexible pipe provides attachment skeleton, can flatten rotation, impact broken bubble on a large scale.Because the syringe needle of puncture venting pin is sharp-pointed, directly launched by venting pin very easily to scratch coat of the stomach in cud, the present invention adopts twice expansion head it off, first time expands into half deployed condition, in this case, injection does not flatten bottom portion, but enough each needle head body scatter, then infolding under the pulling of needle spring, hidden by syringe needle in this way, and then carry out second time expansion, second time expands into full expand state, in this case, flatten bottom injection portion.In order to exit, pin launches, pipe box in injection portion must being released, release mode is that pressing pressure changes hands handle, pressure pivoted housing pipe moves down, downforce is become the component along cell body and the component perpendicular to cell body by oblique thread groove, because oblique thread groove is comparatively smooth, oblique screw thread frictional force that is convex and oblique thread groove is little, therefore the component along cell body can make oblique screw thread convex edge tiltedly thread groove rotation, and connecting ring is fixedly connected with injection portion, connecting ring rotation can cause whole injection portion to rotate, and because pressure pivoted housing pipe moves down, pressure turns spring and compressed.When oblique screw thread is convex and oblique thread groove mating surface has arrived the end, continue to press down pressure and change hands handle, make injection portion and pressure rotary device rigid contact, downforce makes injection portion slide relative to interior pipe box, and then occur that first time and second time are launched, when injection portion second time is launched, elasticity convex just in time snaps in locating slot and stops injection portion to glide relative to interior pipe box, unclamp the downforce acting on and press and change hands on handle, pressure turns spring playback, lifting force is produced to pressure pivoted housing pipe, pressure pivoted housing Guan Shangyi, oblique thread groove and the convex recompounding of oblique screw thread reverse, pressure change hands handle also on move.Because whole injection portion and pressure rotary device have all moved down relative to interior pipe box, can not playback completely so pressure changes hands handle, but pressure changes hands handle still has enough strokes to make injection portion rotate for pressing down pressure pivoted housing pipe, user can control the speed that presses down and reach the object controlling injection portion rotating speed, can first quick rotation, smash bubble in cud based on machinery, then slow down velocity of rotation, based on the broken bubble of herbal sprinkling.By rotating, injection portion can smash a part of bubble, and because the rotation of medicinal liquid is sprayed, spray area is large, and medicinal liquid de-bubble effect also significantly promotes.Venting portion of the present invention can effectively prevent the chyme blocking bleed passage that bubble sticks together from also can control venting rhythm and venting speed, the present invention adopts adjustable pipe to regulate, adjustable pipe outer wall againsts bleed passage inwall, flexure strip is provided with at each air vent place, by flexure strip, air vent is sealed, by this design, bleed passage is sealing in the ordinary course of things, prevent the chyme that bubble sticks together from entering air vent, after injection portion works a period of time, bubble is eliminated totally, and then the motion of regulating and controlling pipe is exitted.Easily make ruminant secondary other diseases owing to exitting continuously and healthily, periodically exit, therefore, in certain hour, the adjustable pipe pressed also wants energy resilience, reseals bleed passage.In concrete operations, often there will be operator and forget the time, deflation time is oversize causes ruminant cerebral anoxia, and deflation structure of the present invention can resilience voluntarily, the problem that when solving operation, deflation time is not easily held.Air bleeding step is as follows: press release button, and the mover of contact switch contacts with stator, and electric magnet is energized, when the electric magnet that ferromagnetism block is energized attracts to move down, adjustable pipe can be driven to move down, and rebound spring compresses, and the slow air bag that rises compresses, delay and rise air pressure rising in air bag, gas backs down valve block and overflows, and meanwhile, moves away air vent under flexure strip, adjustment hole partly or entirely aligns with air vent, and bleed passage is opening partly or entirely.After unclamping release button, the mover of contact switch is separated with stator, electric magnet power-off, now downforce disappears, the rebound spring of compression has the trend of resilience, but delay and rise air bag because of lack of air in capsule, under pull-back forces, the slow air bag that rises produces negative pressure, hinders rebound spring resilience, and air slowly flows into delay by micropore and rises air bag, the slow air pressure risen in air bag is made to continue to rise, that hinders rebound spring resilience insists on continuous reduction, moves, finally on adjustable pipe is slow, flexure strip and air vent again screens seal, and bleed passage is closed.By regulating micropore size, the speed of the pre-designed adjustable pipe return of energy, is made device can control rhythm of exitting voluntarily, the size of the area that alignd with air vent by regulating and controlling hole, reaches the object regulating venting speed.The present invention the deflation structure of resilience voluntarily can greatly can save time of patient, allows patient to carry out other work during exitting simultaneously.One end that check valve is arranged in adjustable pipe is provided with sieve plate, can prevent the foreign material in adjustable pipe from entering slow liter in air bag.
Outer pipe shell of the present invention is provided with scale strip and depth adjustment block, the effect of this structure is that auxiliary user arranges puncture venting pin insertion depth.Because ruminant varies, puncture venting pin insertion depth is different, depth adjustment block is slided into appropriate location fix again, make depth adjustment block to this section of needle body length just in time this animal suitable of syringe needle, puncture venting is needled in the process of animal rumens, when depth adjustment block has been attached to animal abdominal wall, stop thrusting.
The present invention is also provided with pressure sensor, and user can be made to know cud internal gas pressure easily, estimates venting number of times and treatment time.
To sum up, the present invention has can take into account injection defoamer and venting, and can Non-follow control injection portion rotating speed when injectable drug, bubble in cud smashed by machinery effectively, prevent the chyme blocking bleed passage that bubble sticks together, simultaneously can large area, in all directions in the advantage of tumor affuse medicament within stomach, the present invention also controls venting rhythm, by pressure sensor monitoring cud internal gas pressure by electromagnetism pushing box, while alleviating patient's working strength, automatically can also control venting rhythm and speed, and needle body insertion depth can be preset.
