Abstract

The utility model relates to a medical transfusion device. The provided structure is that the rear end of a filter in the transfusion device is connected with a transfusion pipeline in an interface mode, that is, the rear end of the filter is provided with a flared interface, and the end head connected with the rear end of the filter is designed to be a joint made of hard materials. When the transfusion tube is connected with the filter, the joint of the transfusion tube is inserted into the flared interface of the filter to form a close connecting structure. The transfusion tube is separated from the filter at the interface; when liquid is injected into a vein, the liquid is injected from the interface. The utility model can ensure all medicaments in injection liquid to be effectively filtered like intravenous transfusion after intravenous injection and blood transfusion.

Description

The syndeton of intravenous transfusion device middle filtrator

This utility model relates to the medical transfusion apparatus, mainly proposes a kind of syndeton of intravenous transfusion device middle filtrator.

Venous transfusion all adopts disposable intravenous infusion set clinically now, cross infection in its process capable of reducing using, it is provided with defecator at front end in addition, can effectively filter many injections and infusion medicine, has reduced harm and adverse consequences to venous patient.Filter is arranged between drop regulator and the syringe needle tube, it adopts interface to be connected with syringe needle tube, think when needs are injected venous patient, from seam with syringe needle tube and front end syringe needle and transfusion device body portion from, and from seam inject medicine or transfuse blood after transfusion, because interface is positioned at the filter front end, contamination particle can not effectively be filtered and directly push vein, many patients are suffered, lost the safety of disposable transfusion device when intravenous injection.

The purpose of this utility model promptly is to improve the syndeton of disposable transfusion device middle filtrator, make its when intravenous injection and the transfusion after the blood transfusion still can have filtration preferably.

This utility model is finished the technical scheme that its invention task takes: the agent structure of disposable transfusion device and the agent structure of filter are not changed, the filter rear end takes interface mode to be connected with liquid-transport pipe-line, it is the interface of filter back end design one toroidal, the tube for transfusion termination that is connected with the filter rear end is designed to the joint of hard material, and the joint of tube for transfusion inserts the interior formation sealing of the filter interface syndeton of toroidal during connection.

Structural design of the present utility model is owing to inject from the filter back end interface during intravenous injection, in the time of can guaranteeing intravenous injection with the blood transfusion after transfusion the same with venous transfusion, all medicines all can effectively filter, and this structure does not influence original agent structure, and clinical effectiveness is better.

Embodiment:

Accompanying drawing 1 is the intravenous transfusion device structural representation.

Accompanying drawing 2 is a transfusion device middle filtrator johning knot composition.

The embodiment that provides with reference to accompanying drawing is further specified its structure:

As shown in Figure 1: disposable intravenous infusion set comprises tube for transfusion 1, dropper 2, actuator 3, filter 4 and syringe needle tube 5 and syringe needle 6; This agent structure all adopts existing structure, does not change.

As shown in Figure 2: the front end of filter 4 and syringe needle tube 5 are connected by interface, and the back end design of syringe needle tube 5 has interface 7, and the joint 8 of filter front end is connected with interface 7; Improvement structure of the present utility model is: filter 4 takes interface mode to be connected with the tube for transfusion of its rear end, it is the interface 9 that filter 4 back end design have a toroidal, connected tube for transfusion termination is designed to the joint 10 of hard material, and joint 10 inserts the interface 9 interior formation sealing syndetons of toroidal.

When needing intravenous injection, joint 10 is separated with interface 9, inject medicine or the transfusion of blood transfusion back etc. from interface 9 and get final product.

Claims

1, a kind of syndeton of intravenous transfusion device middle filtrator, transfusion device comprise tube for transfusion (1), dropper (2), actuator (3), filter (4) and syringe needle tube (5) and syringe needle (6); It is characterized in that: filter (4) takes interface mode to be connected with the tube for transfusion (1) of its rear end, it is the interface (9) that filter (4) back end design has a toroidal, connected tube for transfusion termination is designed to the joint (10) of hard material, and joint (10) inserts the interior formation sealing of interface (9) syndeton of toroidal.
