Description
Technical field
The invention belongs to technical field of medical instruments, specifically referring to a kind of H-matic pressure control infusion pump for carrying out controlling in real time to the infusion velocity of liquid and infusion pressure.
Background technology
Not identical with the requirement of infusion pressure to amount of infusion under different medical situation yet, as during general out patient service patient infusion to the accurate requirement of the amount of infusing in the unit interval and infusion pressure, and during the infusion of some vasoactive agents in operation process, need there is accurate control to amount of infusion in the unit interval, for massive hemorrhage patient transfusion and blood transfusion then need to carry out certain control to infusion pressure.Therefore, for adapting to different medical situation, need to adopt different liquid infusion equipment.
The method that existing solution liquid infusion speed and infusion pressure change in the market has instillation, inject and the mode of roller type perfusion.Instillation is the infusion that the pressure taking liquid natural-drop to produce carries out liquid, and advantage is that structure is simple, easy to operate, cost is low, but cannot the infusion pressure of liquid with precise control, also cannot complete the infusion problem that instantaneous level pressure solves large quantity of fluid; Injecting is the infusion taking the specific Mechanical course principle thrust produced at the uniform velocity to control liquid, advantage is the amount of infusion that can control accurately in the unit interval, but the control structure of its infusion device complexity, 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), the infusion of large quantity of fluid cannot be carried out easily; And roller type perfusion takes roller extruding liquid-transport pipe-line to produce certain pulse pressure and carries out the infusion of liquid, advantage does not have special requirement to the amount of infusion liquid, arbitrarily can regulate infusion velocity, at present the sole mode that controlling quantizes infusion is carried out to large quantity of fluid, but when adopting its infusion, liquid can form impulse wave in the transmission, constant infusion pressure cannot being provided thus affecting some specific check results, the tangible blood cell composition in blood may be destroyed especially when carrying out blood infusion due to the extruding of roller.
Summary of the invention
Object of the present invention is exactly for the deficiencies in the prior art, provides a kind of and can control the speed of infusion and the H-matic pressure control infusion pump of pressure in real time in infusion process.
For achieving the above object, H-matic pressure control infusion pump of the present invention, 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:
Be provided with liquid inlet joint between described inlet and upper tubing, 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, abuts coordinate with the upper tubing mouth of pipe; Described upper valve core valve body periphery offers some upper valve core fluid passages;
Fluid joint is provided with between described liquid outlet and lower tube for transfusion, a bottom spool is provided with in described fluid joint, the axis part of described bottom spool offers bottom spool central liquid passage, described bottom spool is made up of bottom spool end and bottom spool valve body, bottom spool end is tapered, abuts coordinate with the liquid outlet mouth of pipe; Described bottom spool valve body periphery offers some bottom spool fluid passages; Be provided with between described bottom spool valve body with lower tube for transfusion and abut spring.
Further, described inlet internal diameter is greater than described liquid outlet internal diameter, is convenient to the savings of liquid in silica gel balloon urinary like this.
Again further, be provided with check-valves in described liquid outlet, this check-valves only allows liquid from silica gel balloon urinary downward tube for transfusion direction one-way flow, thus can effectively prevent silica gel balloon urinary after being squeezed resilience at present in tube for transfusion liquid flow back to silica gel balloon urinary.
Also further, described bottom spool tip internal diameter is less than liquid outlet internal diameter, the top of described like this bottom spool end can abut and stretch into a liquid outlet part, can closely cooperate with liquid outlet and bottom spool can be pushed open when fluid pressure acquires a certain degree in liquid outlet.
Also further, described fluid joint is provided with pressure detector, the inwall that the pressure detecting probe of described pressure detector is arranged on fluid joint contacts with the liquid phase in fluid joint, such pressure detector can detect the pressure size of infusion liquid in silica gel balloon urinary in real time, thus can realize controlling in real time infusion liquid pressure, and infusion liquid under caning be controlled in 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 H-matic pressure control infusion pump of the present invention is: under normal automatic infusion situation, this H-matic pressure control infusion pump is vertically placed, 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 abutting spring arranged between bottom spool valve body with lower tube for transfusion, the top of bottom spool end under automatic infusion state is in and abuts against state with liquid outlet, the liquid stream in silica gel balloon urinary automatically normally carries medicinal liquid after liquid outlet, bottom spool central liquid passage, lower tube for transfusion.In infusion process, when needs strengthen groundwater increment, manual squeezing silica gel balloon urinary, by fluid pressure effect in silica gel balloon urinary, upper valve core is up, the mouth of pipe of upper valve core end abutment upper tubing, prevents the liquid in silica gel balloon urinary to flow backwards; Bottom spool is descending by fluid pressure effect in liquid outlet, compression abuts spring contraction, bottom spool end and liquid outlet are separated, liquid in silica gel balloon urinary can simultaneously by bottom spool central liquid passage and bottom spool fluid passage dirty, make that the liquid hydraulic pressure in lower tube for transfusion increases, flow increases, the function of acceleration, dosage, pressurization infusion liquid can be realized.
The structure of H-matic pressure control infusion pump of the present invention is simple, easy to operate, can realize controlling infusion velocity and pressure in real time in infusion process, for providing safety guarantee by the capacity of Continuous Perfusion liquid-retentive particular cavity lacuna and pressure within a certain period of time, avoid because hypertonia causes by liquid person visceral organ injury; Meanwhile, also eliminate the impulse wave formed by roller type reperfusion mode, and because the extruding of roller is to the destruction of the tangible blood cell composition in blood when carrying out blood infusion.
