CN2526014Y - Disposable transfusion system convenient to push - Google Patents

Abstract

The utility model provides a disposable transfusion system convenient to push, which is structured in that a push tab for pushing liquid medicine is arranged on the infusion pipe which is between the throttle valve and the filter of the prior disposable transfusion system; an inner tuber piston is arranged inside the cavity of the push tab; and a dust preventing cover is positioned at the end port of the push tab. Compared with the prior art, the convenient-push disposable transfusion system has the characters that the design is reasonable, the structure is simple and the usage is flexible and convenient, and the push type iatrogenic infection and the entering of the gas bubble are prevented. The utility model can completely overcome the disadvantage that the prior transfusion system is singly used and the danger that the liquid medicine is directly pushed into the vein without being filtered to cause various diseases is avoided. Therefore, the utility model is worth being popularized.

Description

Conveniently inject disposable transfusion device

1, technical field

This utility model relates to a kind of medical apparatus and instruments, specifically a kind of disposable transfusion device of conveniently injecting.

2, technical background

Is that the doctor is the Therapeutic Method of normal use of patient treatment disease by transfusion device to patient's body angular vein transfusion.Medical personnel also will add some drugs to improve therapeutic effect temporarily in infusion bottle according to the needs of treatment in the infusion treatment process, sometimes medical personnel inject the time for the concentration, the shortening that improve injection liquid, also will be directly by transfusion needle injection liquid in vein.

All parts that the in use existing deficiency of the transfusion device of prior art is a transfusion device can be from filter be pulled up except transfusion needle, remainder all is fixed together, can only do transfusion device uses, when needing injection liquid, so not only may cause nosocomial infection, and usually enter a small amount of bubble, cause unnecessary dispute.Because the formula of injecting does not add filtration, medical personnel can only pull up the tube for transfusion interface, be connected on syringe and make intravenous injection on the tube for transfusion, owing to be not with filter on the transfusion needle, medical personnel are easy to the impurity particle in the medicinal liquid injected in patient's body and cause other diseases when doing the medicine intravenous injection by syringe.

3, summary of the invention

The purpose of this utility model provides a kind of simple in structure, easy to use, and that can carry out in infusion process that medicinal liquid injects conveniently injects disposable transfusion device.

The purpose of this utility model realizes in the following manner, inject and chew on the tube for transfusion between choke valve and the filter, setting up a medicinal liquid under the situation that does not change original disposable transfusion device structure, chew through filter and transfusion needle directly to intravenous injection by injecting.

Accompanying drawing is for conveniently injecting the structural representation of disposable transfusion device.

With reference to Figure of description the disposable transfusion device of conveniently injecting of the present utility model is explained below doing.

4, description of drawings

The disposable transfusion device of conveniently injecting of the present utility model, as shown in drawings, its structure is to set up one to be used for injecting of injection liquid and to chew 4 on the choke valve 1 of existing disposable transfusion device and the tube for transfusion 3 between the filter 2, inject chew be provided with in 4 the inner chamber in plug 5, inject and chew 4 port part and be provided with dust cap 6.

5, embodiment

Its processing and fabricating of disposable transfusion device of conveniently injecting of the present utility model is very simple and convenient, and processing technology and materials processing making by the prior art transfusion device shown in the by specification accompanying drawing get final product.

The disposable transfusion device of conveniently injecting of the present utility model is compared with existing technology, and has design and closes Reason, the characteristics such as simple in structure, esy to use, safe and reliable can prevent the hospital-acquired infection of injection-type With enter bubble, the transfusion device that has overcome prior art fully is single to be used and avoids injection liquid not add Filter the danger that directly enters vein and cause various diseases. Thereby, have the valency of well promoting the use of Value.

Except the described technical characterictic of specification, be the known technology of those skilled in the art.

Claims (1)

1. conveniently inject disposable transfusion device, it is characterized in that setting up on the choke valve of existing disposable transfusion device and the tube for transfusion between the filter one is used for injecting of injection liquid and chews, inject and be provided with interior plug in the inner chamber of chewing, inject the port part of chewing and be provided with dust cap.
