Abstract

The utility model relates to a prevent class air defence and return blood transfusion system belongs to medical instrument's technical field, including bottle stopper puncture device, the device that admits air, luxuriant fei shi burette, transfer line, flow regulator, liquid medicine filter, venous transfusion needle, its characterized in that: be equipped with the sealed dish that can open and close in the turned welt reason in the luxuriant fei shi burette on the drain pipe inner tube, the fixed balancing disk in sealed lower surface center of coiling, the diameter that seals up the dish is greater than the diameter of the turned welt reason of drain pipe inner tube upper end, and the diameter of balancing disk is lighter than the diameter of the turned welt reason on the drain pipe inner tube, connects a floater above sealed the coiling. The advantage is: utilize the switching of the sealed dish of gravity control of buoyancy and the balancing disk of liquid, effectively prevent below the luxuriant luxuriant and rich with fragrance burette of air admission to reach the effect of preventing back blood simultaneously in the transfer line, the utility model is suitable for an improvement to various transfusion systems.

Description

Anti-stream air defence blood-returning transfusion system
Technical field
This utility model relates to a kind of transfusion device, belongs to the technical field of medical apparatus and instruments.
Background technology
Transfusion device carries out the indispensable utensil of infusing to patient, existing transfusion device is when infusing, there is following shortcoming: after one, liquid bottles liquid is totally lost, liquid can continue to flow downward until liquid in pipe pressure of infusing is suitable with venous pressure, cause large quantity of air in tube for transfusion, great threat is caused to patient safety; Two, be that air is easy to enter human body when pressure transfusion, may air embolism be produced; Three, be when changing liquid, during the medicine of particularly some chemotherapeutic of infusion or zest, high volatility, often can find that liquid has been instilled in the following tube for transfusion of luxuriant luxuriant and rich with fragrance dropper, nurse is needed liquid to be discharged to outside, both medicine is wasted like this, can not ensure to input the dose in patient body, but also by the active drug exposure of band contaminated environment in atmosphere, the health of patient, medical personnel can be had an impact; Four, be easily occur blood back phenomenon.
Summary of the invention
Problem to be solved in the utility model is to provide one and releases air defence blood-returning transfusion system, and this transfusion device can close liquid-transport pipe-line in time when medicinal liquid is about to be totally lost, and prevents air from entering in the following tube for transfusion of luxuriant luxuriant and rich with fragrance dropper, the generation of anti-return blood.
In order to solve the problem, the technical solution adopted in the utility model is: anti-stream air defence blood-returning transfusion system, comprise bottle plug puncture unit, air inlet device, Murphy type burette, tube for transfusion, flow regulator, liquid medicine filter, venoclysis needle, it is characterized in that: in described Murphy type burette, in drain pipe, the turned welt edge of pipe upper end is provided with a seal disc that can open and close, a balancing disk is fixed in the lower surface center of seal disc, the diameter of seal disc is greater than the diameter of the turned welt edge of pipe upper end in drain pipe, the diameter of balancing disk is less than the diameter of the turned welt edge of pipe upper end in drain pipe, a ball float is connected above seal disc.
Preferably, described airtight dish is connected with the turned welt edge point-like of pipe upper end in drain pipe by joint, and airtight dish can be node with junction point, in sector movable, and the function that silk thread opens and closes.
Preferably, in described drain pipe, the turned welt edge of pipe upper end is flare openings, makes balancing disk below be easy to fall in drain pipe.
Preferably, described seal disc is connected by connecting rod or silk thread with ball float.
Preferably, a balance gag lever post that can move up and down together with balancing disk is set below described balancing disk.
When normal infusion, have a certain amount of medicinal liquid in dropper, ball float is subject to buoyancy moves pulling open seal disc, medicinal liquid can constantly enter in drain pipe, infuse normally, after the medicinal liquid in medicinal liquid bottle drips off, the liquid level in dropper starts to decline, ball float also declines thereupon, seal disc covers the turned welt edge of pipe upper end in drain pipe, closes infusion pipeline, and remains certain liquid level and pressure, air can not enter in tube for transfusion below, also can not blood back in tube for transfusion.
This utility model compared with prior art, advantage is: the opening and closing utilizing the buoyancy of liquid and the GRAVITY CONTROL seal disc of balancing disk, thus control the flow regime of liquid, effectively prevent air from entering in the following tube for transfusion of luxuriant luxuriant and rich with fragrance dropper, reach the effect of pre-blood return prevention, this utility model is applicable to the improvement to various transfusion device simultaneously.
Accompanying drawing explanation
Fig. 1 is that this utility model embodiment 1 is about to structural representation when being totally lost seal disc closedown at liquid.
Fig. 2 is the structural representation of this utility model embodiment 1 when normal infusion seal disc is opened.
Fig. 3 is the structural representation of this utility model embodiment 2.
In figure: 1, Murphy type tube body; 2, ball float; 3, connecting rod; 4, the turned welt edge of pipe upper end in drain pipe; 5, airtight dish; 6, drain pipe; 7, balancing disk, 8, balance gag lever post.
Detailed description of the invention
Embodiment 1: as shown in Figure 1-2, anti-stream air defence blood-returning transfusion system, comprise bottle plug puncture unit, air inlet device, Murphy type burette, tube for transfusion, flow regulator, liquid medicine filter, venoclysis needle, it is characterized in that: in described Murphy type burette 1, in drain pipe, the turned welt edge 4 of pipe upper end is provided with a seal disc that can open and close 5, a balancing disk 7 is fixed in the lower surface center of seal disc 5, the diameter of seal disc 5 is greater than the diameter of the turned welt edge 4 of pipe upper end in drain pipe, the diameter of balancing disk 7 is less than the diameter of the turned welt edge 4 of pipe upper end in drain pipe, seal disc 5 connects a ball float 2 above, described airtight dish 5 is connected with turned welt edge 4 point-like of pipe upper end in drain pipe by joint, airtight dish 5 can take junction point as node, in sector movable.In described drain pipe, the turned welt edge 4 of pipe upper end is in flare openings, and described seal disc 5 is connected by connecting rod 3 or silk thread with ball float 2.
Embodiment 2: as shown in Figure 3, connected mode between the turned welt edge that the present embodiment and the difference of embodiment 1 are pipe upper end in seal disc and drain pipe is different, in the present embodiment, a balance gag lever post 8 that can move up and down together with balancing disk is set below described balancing disk 7, balance gag lever post 8 should have enough length to ensure to depart from drain pipe, play and seal disc is limited in the range of activity that can only move up and down, increase the weight of balance gag lever post 8 in the present embodiment, can balancing disk be omitted.
