Abstract

The utility model provides a pressurizing transfusion system for clinic transfusion, which is an innovative improvement of the prior transfusion system. The structure of the utility model is that a transfusion plug is arranged on a perfusion tube in turn provided with a burette, a speed governor, a filter and a transfusion needle, the transfusion plug is provided with an inlet branch communicated with an inner hole of the plug, the end of the inlet branch is provided with a three way cock, the inlet branch is provided with an air filter, and the other two tie-ins of the three way cock are respectively provided with a rubber cap and a one-way valve rubber tube. With a novel structure, convenient use, no externally sprayed medicinal fluid, wide applications and disposable property, the utility model can effectively avoid the cross infection, which is beneficial to both patients and medical care personnel.

Description

Pressurizing infusion set

This utility model relates to a kind of pressurizing infusion set of using as venous transfusion in clinical.

Venous transfusion is a matter of frequent occurrence in the clinical treatment, in order to improve the transfusion effect, is absolutely necessary sometimes to infusion bottle gas transmission pressurization in infusion process.Vein pressure transfusion syringe commonly used is injected air by the transfusion device exhaustor in bottle at present.But because of the exhaustor opening is connected not tight with syringe, cause liquid to spray in the operation easily, and operation the time must there be two medical care personnel cooperate to finish from joining place, so both manpower and time had been wasted, increased infection chance, be inconvenient to again treat, all unfavorable to patient and medical personnel.

The purpose of this utility model provides a kind of novel pressurizing infusion set, can solve the pressurization problem in the venous transfusion effectively.

The purpose of this utility model is achieved like this, on the basis of existing transfusion device structure, improve, promptly on the transfusion plug body rear portion of transfusion device, adorn the air inlet pipe that communicates with the plug endoporus, the three way cock is housed on the air inlet pipe, the three way cock is with on the air inlet pipe between the transfusion plug air filter being housed together, the three way cock's is equipped with rubber cap and unidirectional flap valve rubber tube respectively on two joints in addition, other structures are with existing transfusion device, the plug of promptly infusing is contained on the tube for transfusion, and dropper is housed on the tube for transfusion successively, speed regulator, filter and venoclysis needle is housed through joint.

Its novel structure uniqueness of this utility model, easy to use, safety, easy and simple to handle, human-saving saves time, and is effective, can not cause infection because of pressurization in the transfusion, patient is relieved, and medical personnel save worry, and is a creative innovation to existing transfusion device, popularizing application prospect light.

Below in conjunction with accompanying drawing structure of the present utility model is elaborated.

Fig. 1 is this utility model structural front view.

Fig. 2 is a unidirectional flap valve rubber tube section of structure (amplification) in this utility model structure.

By shown in Figure 1, this utility model is that transfusion plug 1 is contained on the tube for transfusion 2, dropper 3, speed regulator 5, the filter 6 of band rubber cap 4 are housed on the tube for transfusion 2 successively, the transfusion needle 8 of band needle handle 9 is equipped with in tube for transfusion 2 terminations through joint 7, on the body rear portion of transfusion plug 1 air inlet pipe 10 that communicates with the plug endoporus is housed, air inlet pipe has three way cock 12 on 10 terminations, three way cock 12 is with being equipped with air filter 11 on the air inlet pipe 10 between the transfusion plug 1, and three way cock's 12 is equipped with rubber cap 13 and unidirectional flap valve rubber tube 14 respectively on two joints in addition; Unidirectional flap valve rubber tube 14 is the agnail taper, and the outside is equipped with and is tightened rubber sleeve 15, and unidirectional flap valve 16 is arranged in the center cavity.Unidirectional flap valve rubber tube can directly adopt the existing unidirectional flap valve rubber stopper of medically using to get final product, and needn't manufacture in addition, also can adopt other structures, can disposablely be injection molded into.Unidirectional flap valve 16 is the rubber patch in flexible hole, a center, and springhole externally opens under the pressure during air inlet, but air inlet, and when pressurization stopped, springhole sealed automatically, prevented gas leakage.

During transfusion infusion needle is inserted in the infusion bottle, remove syringe needle with the 10-20ml syringe, nipple is inserted pressurization flap valve rubber tube, inject air, simultaneously another breather of tee T is built with rubber cap, made to become malleation in the infusion bottle, because of this flap valve rubber tube can only air inlet can not be discharged gas, pressure of the inside of a bottle is constantly increased, thereby reach the purpose of quick transfusion.When pressurization finishes, tee T one end rubber fur cap can be removed, atmospheric pressure can normally be passed through, and keep general transfusion.

This utility model pressurized operation is easy, only need one man operation, and can not cause medicinal liquid to spray outward, and be the disposable thing of using, can avoid cross infection effectively, both can be used for outside the quick transfusion of dehydrant, the blood transfusion and infusion, the vein that also can be used for shock patient are imported contrast agent etc. fast, and clinical practice is very extensive, and it is applied and must be welcome by people, produce good economy and social effect, bring benefit to the mankind.
