Abstract

The utility model relates to a cork puncture outfit of a transfusion system, which comprises an air inlet needle (3), a liquid inlet component (2) and an air inlet protection stopper (4), wherein the air inlet needle (3), the liquid inlet component (2) and the air inlet protection stopper (4) are fixedly arranged on a puncture outfit base (1). The front part of the liquid inlet component (2) is conical and is provided with three liquid inlets (20) of the same size. The access of the air inlet needle (3) is arranged in the center of the liquid inlet component (2). The utility model has the advantages of stronger puncture performance, humanized handle and labor-saving operation, and can effectively prevent the desquamation caused by the puncture from blocking the pipeline.

Description

The transfusion device bottle plug puncture unit

Technical field

This utility model relates to a kind of transfusion device bottle plug puncture unit, relates in particular to the puncture air inlet needle of this transfusion device bottle plug puncture unit and the structure between the puncture feed liquor spare.

Background technology

Transfusion is the method for a kind of extensive use in clinical treatment, especially improves now at medical level, and the disposable infusion product more is subjected to paying close attention to widely.

Traditional transfusion device is to adopt earlier to insert the feed liquor pin, injects air tube again, the very trouble that operates, and easily produce the plug exfoliation and produce pipeline blockage.

Though the Plastic bottle plug perforator that generally adopts does not need to repeat to insert bottle recently, because diameter is thicker, need exert oneself to puncture, and uses inconvenience.

By Figure 1A as seen: the recent Plastic bottle plug perforator that adopts protects plug 40 by a perforator 10 and air inlet to be formed, and is made up of inlet opening 101 and air inlet 102 on the perforator, and inlet opening 101 has only one, as producing exfoliation the congestion affects infusion process takes place very easily.

Summary of the invention

This utility model technical issues that need to address have provided a kind of transfusion device bottle plug puncture unit, are intended to solve the above problems.

In order to solve the problems of the technologies described above, this utility model is achieved through the following technical solutions:

This utility model comprises: an air inlet needle, and plug is protected in a feed liquor spare, an air inlet; Described air inlet needle, feed liquor spare and air inlet are protected the plug fixed in position on the perforator seat; The front portion of described feed liquor spare is pyramid type and has three inlet openings that size is identical; The path of described air inlet needle is placed in the center of feed liquor spare.Compared with prior art, the beneficial effects of the utility model are: the puncture ability is stronger, and the new type handle operation is more laborsaving; The obstruction that can effectively stop the exfoliation that causes because of puncture that pipeline is taken place.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment this utility model is described in further detail:

By Fig. 2 A, Fig. 2 B as seen: this utility model comprises: plug 4 is protected in 3, one feed liquor spares of an air inlet needle 2, an air inlet; Described air inlet needle 3, feed liquor spare 2 and air inlet are protected plug 4 fixed in position on perforator seat 1; The front portion of described feed liquor spare 2 is pyramid type and has three inlet openings 20 that size is identical; The path of described air inlet needle 3 is placed in the center of feed liquor spare 2;

Described air inlet needle 3 is pins of being made by metal material.

Perforator seat in this utility model adopts the handle of human oriented design, and the more comfortable feel of controlling is arranged in operation, operates more laborsaving.

The puncture air inlet needle is made by metal material in this utility model, and the puncture ability is stronger, and the new type handle operation is more laborsaving.Puncture feed liquor spare is made of plastics, and the front portion is a pyramid type, and has three inlets, and is reasonable in design, accelerates feed liquor speed greatly, and cost is lower, has higher use value.

Three inlets of outstanding design can effectively stop the obstruction that the exfoliation that causes because of puncture takes place pipeline in the feed liquor spare.

Claims

1. transfusion device bottle plug puncture unit comprises: an air inlet needle (3), and plug (4) is protected in a feed liquor spare (2), an air inlet; Described air inlet needle (3), feed liquor spare (2) and air inlet are protected plug (4) fixed in position on perforator seat (1); It is characterized in that: the front portion of described feed liquor spare (2) is pyramid type and has three inlet openings (20) that size is identical; The path of described air inlet needle (3) is placed in the center of feed liquor spare (2).
