Description
Technical field
This utility model belongs to technical field of medical instruments, specifically refers to a kind of auto-manual pressure control infusion pump of controlling in real time of carrying out for the infusion velocity to liquid and infusion pressure.
Background technology
Not identical to the requirement of amount of infusion and infusion pressure under different medical situations yet, during as general out patient service patient infusion, the amount of infusing in the unit interval and infusion pressure are not had to accurate requirement, and when the infusion of some vasoactive agents in operation process, need to there is accurate control to amount of infusion in the unit interval, need infusion pressure to carry out certain control for massive hemorrhage patient's transfusion and blood transfusion.Therefore,, for adapting to different medical situation, need to adopt different liquid infusion equipment.
The method of existing solution liquid infusion speed and infusion pressure change has instillation, injects and the mode of roller type perfusion in the market.Instillation is to take pressure that liquid natural-drop produces to carry out the infusion of liquid, advantage be simple in structure, easy to operate, cost is low, but infusion pressure that cannot liquid with precise control, also cannot complete instantaneous level pressure and solve the infusion problem of large quantity of fluid; Inject is to take specific mechanical control principle to produce the infusion of thrust control liquid at the uniform velocity, advantage is to control accurately the amount of infusion in the unit interval, but the control structure complexity of its infusion device, complex operation, cost are high, and can only be the liquid transfer of carrying out in a certain amount of (being generally no more than 60ml), cannot carry out easily the infusion of large quantity of fluid; And roller type perfusion is to take roller extruding liquid-transport pipe-line to produce that certain pulse is pressed and the infusion that carries out liquid, advantage is that the amount of infusion liquid is not had to special requirement, can arbitrarily regulate infusion velocity, it is the sole mode that at present large quantity of fluid is carried out controlled quantification infusion, but while adopting its infusion, liquid can form impulse wave in transmission, thereby cannot provide constant infusion pressure to affect some specific check results, special in the time carrying out blood infusion because the extruding of roller may destroy the tangible blood cell composition in blood.
Summary of the invention
The purpose of this utility model is exactly for the deficiencies in the prior art, provides a kind of and can in infusion process, control the speed of infusion and the auto-manual pressure control infusion pump of pressure in real time.
For achieving the above object, auto-manual pressure control infusion pump of the present utility model, comprises silica gel balloon urinary, described silica gel balloon urinary two ends are respectively equipped with inlet and liquid outlet, described inlet is connected with upper tubing, and described liquid outlet is connected with lower tube for transfusion, and its special character is:
Between described inlet and upper tubing, be provided with liquid inlet joint, be provided with a upper valve core in liquid inlet joint, described upper valve core is made up of upper valve core end and upper valve core valve body, and upper valve core end is tapered, coordinates with upper tubing mouth of pipe butt; Described upper valve core valve body periphery offers some upper valve core fluid passages;
Between described liquid outlet and lower tube for transfusion, be provided with fluid joint, in described fluid joint, be provided with a bottom spool, the axis part of described bottom spool offers bottom spool center fluid passage, described bottom spool is made up of bottom spool end and bottom spool valve body, bottom spool end is tapered, coordinates with liquid outlet mouth of pipe butt; Described bottom spool valve body periphery offers some bottom spool fluid passages; Between described bottom spool valve body and lower tube for transfusion, be provided with butt spring.
Further, described inlet internal diameter is greater than described liquid outlet internal diameter, is convenient to like this savings of liquid in silica gel balloon urinary.
Again further, in described liquid outlet, be provided with check-valves, this check-valves only allows liquid from the downward tube for transfusion direction of silica gel balloon urinary one-way flow, thereby can effectively prevent silica gel balloon urinary resilience liquid silica gel balloon urinary that flows backwards back in tube for transfusion at present after being squeezed.
Also further, top, described bottom spool end internal diameter is less than liquid outlet internal diameter, the top energy butt of described like this bottom spool end also stretches into a liquid outlet part, can closely cooperate with liquid outlet and bottom spool can be pushed open in the time that fluid pressure acquires a certain degree in liquid outlet.
Also further, on described fluid joint, be provided with pressure detector, the pressure detecting probe of described pressure detector is arranged on the inwall of fluid joint and contacts with the liquid phase in fluid joint, pressure detector can detect the pressure size of infusion liquid in silica gel balloon urinary in real time like this, thereby can realize, infusion liquid pressure is controlled in real time, and can be controlled in infusion liquid under constant pressure condition.
Further, the upper valve core fluid passage quantity that described upper valve core valve body periphery is offered is 4～8; The bottom spool fluid passage quantity that described bottom spool valve body periphery is offered is 4～8.
The operation principle of auto-manual pressure control infusion pump of the present utility model is: under normal automatic infusion situation, this auto-manual pressure control infusion pump is vertically to place, due to action of gravity, upper valve core nature is separated with the upper tubing mouth of pipe, and the medicinal liquid in upper tubing can flow into silica gel balloon urinary from the upper valve core fluid passage of upper valve core valve body periphery; Due to the effect of the butt spring arranging between bottom spool valve body and lower tube for transfusion, the top that makes bottom spool end under automatic infusion state in the liquid outlet state that connects, the normal medicinal liquid of carrying automatically of flowing through after liquid outlet, bottom spool center fluid passage, lower tube for transfusion of the liquid in silica gel balloon urinary.In infusion process, in the time that needs strengthen groundwater increment, manual squeezing silica gel balloon urinary, is subject to fluid pressure effect in silica gel balloon urinary, and upper valve core is up, and the mouth of pipe of upper valve core end butt upper tubing has stoped the liquid in silica gel balloon urinary to flow backwards; Bottom spool is subject to the interior fluid pressure effect of liquid outlet descending, compression butt spring contraction, bottom spool end and liquid outlet are separated, liquid in silica gel balloon urinary can be simultaneously dirty by bottom spool center fluid passage and bottom spool fluid passage, the increase of liquid hydraulic pressure, flow in lower tube for transfusion are increased, can realize the function of acceleration, dosage, pressurization infusion liquid.
Auto-manual pressure control infusion pump of the present utility model simple in structure, easy to operate, can in infusion process, realize and control in real time infusion velocity and pressure, for providing safety guarantee by capacity and the pressure of Continuous Perfusion liquid-retentive particular cavity lacuna within a certain period of time, avoid due to the hypertonia person's visceral organ injury that causes being subject to liquid; Meanwhile, also eliminated the impulse wave forming by roller type reperfusion mode, and while carrying out blood infusion due to the extruding of the roller destruction to the tangible blood cell composition in blood.
