The multi-functional transfusion apparatus is characterized in that a floating ball moving groove is design in the bottle stopper puncture device, a floating ball is arranged in the floating ball moving groove, a window is further designed outside the floating ball moving groove, a one-way valve A is arranged on the inner wall of the hose body of the air inlet hose, a syringe connector is arranged on an air filter which is arranged on the upper face of the air inlet hose, and a one-way valve B is further arranged in the transfusion hose.

Description

Multifunctional transfusion system
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of anti-backflow, prevents that air from advancing transfusion device, and can conveniently inject the multifunctional transfusion system that air pressurizes to infusion bottle.
Background technology
Disposable infusion set: a kind of common disposable medical treatment consumptive materials process aseptic process, that set up passage between vein and the medicinal liquid that is mainly used in venous transfusion.It generally is made up of the air inlet of bottle plug puncture unit protective sleeve, bottle plug puncture unit, band air filter and stopper, fluid passage, dropper (dripping kettle, black Fei Shi pipe), liquid medicine filter, injection member, outer cone joint, outer cone joint protective cover, infusion tube, flow (speed) actuator, venoclysis needle etc.The traditional infusion device is that raw material is made with PVC, and high-performance poly alkene thermoplastic elastomer (TPE) is considered to make the safer more high performance material of disposable transfusion device.This product and the supporting use of disposable use venoclysis needle are mainly used in clinical gravity type transfusion.Under the atmospheric pressure effect, the thinner infusion tube of liquid runs down flows into dropping funnel in the bottle, and when dropping funnel water column pressure during greater than venous pressure, the liquid runs down flexible pipe in the bottle flows into vein.The sterilization effect duration of medical worker's preoperation inspection disposable transfusion device and packing have or not gas leakage and other are unusual, take out transfusion device, with cone joint infusion segment bottle, hang infusion bottle on transfusion pole, be vented to medicinal liquid and flow to the infusion tube lower end, fasten actuator, again intravenous needle is thrust the vein that disinfects, after fixing, untie tourniquet, adjust flow velocity.But there is following shortcoming in it: 1, infuse when finishing such as untimely replacing liquid, gas enters transfusion device or human body easily; 2, when the infusion bottle internal pressure was too high, liquid spilt by air inlet pipe, causes waste; 3, venous blood enters transfusion device when low when vein pressure height or transfusion device position are crossed; 4, inconvenient to infusion bottle (bag) pressurization.
Summary of the invention
In order to overcome the described shortcoming of background technology, to realize preventing the air admission transfusion device, anti-venous blood enters transfusion device, and anti-liquid spills, the purpose of convenient pressurization, the technical solution adopted in the utility model is:
A kind of multifunctional transfusion system, comprise bottle plug puncture unit, air induction hose, dropper, flow regulator, infusion tube, venoclysis needle, be connected with air induction hose on the bottle plug puncture unit, be connected with dropper below the bottle plug puncture unit, dropper is connected with venoclysis needle by infusion tube, flow regulator is housed above the infusion tube, it is characterized in that: the bottle plug puncture unit design has the ball float shifting chute, in the ball float shifting chute ball float is housed, window has also been designed in the outside of ball float shifting chute, the inwall of the body of air induction hose is equipped with one-way valve A, and the air filter above the air induction hose is equipped with the syringe nipple interface, and infusion tube also is equipped with one-way valve B.
Described one-way valve A and one-way valve B are lightweight, have elasticity and flexible thin film.
The utility model has the advantages that:
(1), effectively avoid air to be injected into human body, for safe infusion provides guarantee by air induction hose; Do not need aerofluxus, alleviated the labor intensity of nursing; Reduce doctor-patient dispute; Improve nursing quality, improved nurse-patient relationship; Nursing labor intensity and operating pressure have been reduced;
(2), can prevent the anti-transfusion device that flows into of venous blood, effectively avoid blood to solidify external, reduced potential safety hazard and patient's fear;
(3), can prevent that liquid flows out, and has reduced the waste and the pollution of medicinal liquid;
(4), can conveniently in infusion bottle, inject air pressurized and reduced labor intensity, saved the time, improved nursing quality;
(5), be particularly useful for the quick transfusion of hypotension or Hypovolemia;
(6), above-mentioned improvement has advantages such as simple in structure, cost is low, easy to operate, easy realization.
Description of drawings
Fig. 1 is the structural representation of bottle plug puncture unit of the present utility model.
Fig. 2 is a structural representation of the present utility model.
In the accompanying drawing: 1, syringe nipple interface; 2, one-way valve A; 3, admission line; 4, bottle plug puncture unit point; 5, ball float shifting chute; 6, ball float; 7, fluid pipeline; 8, bottle plug puncture unit; 9, air induction hose; 10, dropper; 11, one-way valve B; 12, flow regulator; 13, infusion tube; 14, venoclysis needle; 15, window.
The specific embodiment
Be described further below in conjunction with 1~2 pair of this utility model of accompanying drawing: ball float 6 and ball float shifting chute 5 are set in bottle plug puncture unit 8.The density of ball float 6 is less than water, and it is spherical that ball float 6 is preferably, and also can be square, cylindrical.5 li of ball float shifting chutes, ball float shifting chute 5 adapts to moving up and down of ball float, and the length of ball float shifting chute 5 is greater than floating ball diameter or height, preferably diameter or more than 2 times of height.The width of window 15 is less than the width or the diameter of ball float 6, and the height of window 15 is consistent with the height of ball float shifting chute 5.It above the window 15 bottle plug puncture unit point 4.Ball float 6 rises to ball float shifting chute 5 upper ends when in the infusion bottle liquid being arranged like this, and liquid enters ball float shifting chute 5 by bottle plug puncture unit 8.When in the infusion bottle during no liquid ball float 6 reduce to the lower end of ball float shifting chute 5 and coincide in, liquid that can not continues to flow to fluid pipeline 7, this just can prevent air admission fluid pipeline 7.
