Abstract

The utility model relates to a disposable transfusion system, which is characterized in that an auxiliary transfusion pipe communicated with a transfusion pipe is connected to the transfusion pipe positioned between a filter and a vein needle head, an injector joint is connected with the auxiliary transfusion pipe, the transfusion pipe between a Murphy's dropper and the filter is divided into two sections which are connected with a section of rubber pipe, and a dripping speed regulator 5 is clamped on the rubber pipe. The utility model can simultaneously carry out intravenous injection in intravenous transfusion, and avoids the phenomenon that the dripping speed regulation is false because of the hardness of the transfusion pipe caused by lower temperature.

Description

Disposable transfusion system

The disposable transfusion device that generally uses is by perforator at present, tube for transfusion, Murphy's burette, a fast actuator, filter, the first-class composition of intravenous needle.Usually in transfusion, need the intravenous injection other drug in the treatment; Or according to the treatment needs directly carry out intravenous injection with syringe.When running into above-mentioned situation, must be with the tube for transfusion joint with after filter connector be separated, syringe and tube for transfusion joint are joined just can carry out intravenous injection again, make filter connector contaminated easily like this, use also inconvenient.And the tube for transfusion of existing disposable transfusion device is to be made of plastics, drip fast actuator and be stuck on the tube for transfusion, and plastic tube hardening when weather is low than cold ambient temperature, the roller on the fast actuator skids easily and does not press tightly tube for transfusion, and it is malfunctioning to cause dripping the velocity modulation joint.

The purpose of this utility model is to provide a kind of disposable multifunction transfusion system, and this transfusion can be carried out intravenous injection in transfusion under the situation that treatment needs, and a velocity modulation joint is reliable.

This utility model is realized by following technical scheme:

This utility model is made up of perforator 1, Murphy's burette 2, tube for transfusion 3, a fast actuator 5, filter 6, venous needle 8 etc., the other auxiliary tube for transfusion 12 that communicates with it that is connected on the tube for transfusion 3c of 8 of filter 6 and venous needles, be connected to a syringe adapter 11 on the auxiliary tube for transfusion 12, the tube for transfusion 3b that Murphy's burette 2 and filter are 6 is two sections and joins by one section rubber tube 4, drips a fast actuator 5 and is stuck on the rubber tube 4.

During normal venous transfusion, inject other drug, or need directly carry out intravenous injection the time, syringe is connected with syringe adapter 11 on the auxiliary tube for transfusion 12 as need.Can directly inject, and will not separate with the joint of filter 7 by tube for transfusion joint 6, avoid the contaminated possibility of filter 6 joints.One section rubber tube 4 setting up on the tube for transfusion 3b of 6 of Murphy's burette 2 and filters, and be stuck in the fast actuator 5 that drips on the rubber tube 4 makes in ambient temperature lowlyer, during the hardening of plastics system tube for transfusion, drips velocity modulation and saves unaffected.

Description of drawings:

Fig. 1 is this utility model one example structure figure;

Fig. 2 is another example structure of this utility model figure.

Below in conjunction with drawings and Examples this utility model is further specified.

As shown in Figure 1, 2, auxiliary tube for transfusion 12 can fuse with tube for transfusion 3c and also can be connected by threeway 13, can will assist tube for transfusion 12 and tube for transfusion 3c adhesion during making, as shown in Figure 2, one drainage screen 10 is housed in syringe adapter 11, and 11 also add a closing cock 9 on the syringe adapter.Closing cock 9 plugs when needing intravenous injection, behind auxiliary tube for transfusion 12 of separation and the tube for transfusion 3c, are dialled deblocking plug 9 during normal infusion in syringe adapter 11, connect syringe and get final product.Drip fast actuator 5 and be stuck on the rubber tube 4, when vein is threaded a needle, can make rubber tube 4 complete closed with dripping fully chucking rubber tube 4 of fast actuator 5, the hydraulic pressure that reduces to infuse is convenient to medical personnel and is observed blood back.
