Abstract

The utility model discloses a transfusion device. A side pipe (5) is arranged above a filter (3). A pipe opening of the side pipe (5) inside the filter (3) is positioned above a filtering net (6). The pipe opening of the side pipe (5) has a cover cap (7) corresponding to the side pipe. The pipe diameter of the side pipe (5) is in accordance with a nipple of a syringe or a transfusion three-way pipe. The filter (3) is positioned between a transfusion regulator (2) and a transfusion joint (8). The side pipe (5) on the filter (3) inclines outwards. The utility model solves the problems that a small quantity of air remains above a filter plate and in the position of a kettle center, bubbles easily enter patients' bodies through a scalp needle pipe in the process of transfusion, etc., existing in the existing filter appliance. The utility model has the advantages of simple structure, convenient operation, safety, broad application, etc. The utility model is favorable to patients' health. The utility model can be widely used for intravenous drip and intravenous push.

Description

Transfusion device

Technical field this utility model relates to a kind of transfusion device, more particularly, relates to a kind of clinical transfusion device of giving the patient injection medicinal liquid that is used for.

Background technology in the prior art, generally the filter bits of the disposable transfusion device of Cai Yonging directly is connected with the scalp needle tubing during transfusion in the tube for transfusion terminal of Murphy type burette below; Filter is a microporous membrane filter plate, and hole is crisscross circuitous, is stored in the air at ampulla place, filter both sides and the microbubble that adheres on the screen plate is difficult to be gone out by liquid, and little air residues in screen plate top and ampulla place; In infusion process, microbubble in the filter is mutual " fusion " along with its capillary minimizing, become the bigger flowable state bubble that is, when tube for transfusion moves or patient body position when changing, because hydraulic action makes these bubbles be easy to enter in patient's body by the scalp needle tubing; And to partly needing the patient of intravenous injection medicinal liquid treatment simultaneously, the nurse usually separates transfusion device with the scalp needle tubing, there is suction the syringe of medicinal liquid to be connected again or is connected to the transfusion tee T and come injection liquid with the scalp needle tubing, in view of the scalp needle tubing of clinical use rank and transfusion tee T all do not have defecator, medicinal liquid filtered device flows directly in the body, and the microgranule in the medicinal liquid can have potential threat to the patient; In addition, the nurse separates scalp needle tubing or tee T, has prolonged the operating time, also can increase opportunities for contamination, thereby must improve.

It is a kind of simple in structure, easy to operate, safe in utilization and be beneficial to the transfusion device of patient health that the summary of the invention the purpose of this utility model is to provide.

In order to achieve the above object, this utility model provides following technical scheme: design a kind of transfusion device, a kind of transfusion device, comprise Murphy type burette (1), infusion regulator (2), filter (3) and tube for transfusion (4), Murphy type burette (1) is positioned at the top of transfusion device, filter (3) is positioned at the bottom of transfusion device, infusion regulator (2) be positioned between Murphy type burette (1) and the filter (3) and be can up-down adjustment the activity attitude, the top of described filter (3) has side pipe (5), the lower nozzle of side pipe (5) is positioned at the top of drainage screen (6), the mouth of pipe has the block (7) that adapts with it on the side pipe (5), and the caliber of side pipe (5) and the nipple of syringe or transfusion tee T adapt.Transfusion device of the present utility model can be got rid of inner tiny bubble, the microgranule of medicinal liquid has solved the difficult problem that infusion process exists always, in addition in the time of filtering transfusion and intravenous injection again, block (7) preferably links to each other with side pipe (5) by frenulum (9), and block (7) can not dropped.

This utility model technical scheme preferably can be: filter (3) is positioned between infusion regulator (2) and the infusion connector (8), that is to say, the position of filter is up moved and left the transfusion device end fitting, like this, microgranule in the time of can not only filtering intravenous injection in the medicinal liquid, no matter intravenous drip or intravenous injection enter human body after can both filtering by filter again, avoid the untoward reaction that microgranule causes in the transfusion, have increased the safety coefficient of transfusion.

This utility model technical scheme preferably also can be: the side pipe (5) on the filter (3) is laterally.Make the mouth of pipe and the tube for transfusion of side pipe (5) have certain distance, be convenient to nurse operation.

Compared with prior art, the utlity model has simple in structure, easy to operate and be beneficial to patient health, and can adapt to advantages such as intravenous drip and intravenous injection, on the basis that does not increase patient's burden, reduce gas and microgranule to greatest extent to the influence that the patient causes, improved the feasibility of nurse job efficient.

Be drawing explanation of the present utility model below the description of drawings:

Fig. 1 is existing transfusion device structural representation;

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is the cross-sectional view of this utility model filter.

Among Fig. 1-Fig. 3, the 1st, Murphy type burette, the 2nd, infusion regulator, the 3rd, filter, the 4th, tube for transfusion, the 5th, side pipe, the 6th, drainage screen, the 7th, block, the 8th, infusion port, the 9th, frenulum.

By specific embodiment this utility model is carried out more detailed description below the specific embodiment:

With reference to Fig. 1, the filter (3) of existing transfusion device (4) is positioned at the tube for transfusion terminal of Murphy type burette below, and filter (3) does not have side pipe (5);
