Part of the body, filter and junction block cup joint in that vertical direction is photogenic, and the first cover body and the second cover body are at the photogenic lock of horizontal direction. The utility model discloses in the use, can prevent effectively that filter and junction block from droing safe and reliable because of the tractive.

Description

A kind of transfusion device of improvement

Technical field

This utility model relates to field of medical article technology, particularly relates to the transfusion device of the high improvement of a kind of usage safety performance.

Background technology

The transfusion device of medically a large amount of use at present, its structure is similar, arranges discerptible filter and junction block in one end of the close venipuncture needle of tube for transfusion, and junction block connects venipuncture needle, conveniently use when needs intravenous injection other medicines, avoid the misery that patient's repeated puncture is injected.But when actual clinical transfusion uses, still there is potential safety hazard, involve when causing coming off if this filter and junction block are subject to external force, very easily cause the junction of filter and junction block to pollute, consequence is serious.

Utility model content

For above-mentioned technical problem, this utility model provides a kind of transfusion device of improvement, its novel structure, low cost of manufacture, and during use, slip-off preventing is effective, safety and sanitation.

The technical scheme that this utility model adopts is: a kind of transfusion device of improvement; comprise tube for transfusion, the bottle plug puncture unit be set in turn on tube for transfusion, air intake, dropping funnel, flow regulator, filter, junction block and venipuncture needle; it is characterized in that: also comprise the protective sleeve being arranged at filter and junction block socket place outside; protective sleeve is divided into the first body and the second body, and the first body and the second body are interlocked.

As preferably, described filter and junction block in the vertical direction socket-connect, and the first body and the second body are interlocked in the horizontal direction.

Owing to have employed technique scheme, this utility model has following technique effect: this utility model in use, can effectively prevent filter and junction block from coming off because of tractive, safe and reliable.
