Abstract

The utility model relates to a disposable dispensing needle. The utility model is composed of a needle pipe and a needle bed. The utility model is mainly used for dispensing liquid medicine of transfusion in hospitals. The utility model overcomes the defects existing in a dispensing needle which is nationally used at present, namely, the front end of the needle pipe is made into a conical body with a sharp needle tip (picture two, 3), and a left and a right inclined holes are arranged on the bevel of the conical body (picture two, 4). The condition that particles of a bottle plug enter liquid medicine can be prevented, and the residual quantity of the liquid medicine in the process of dispensation can be decreased.

Description

Disposable use dispensing needle

Affiliated technical field

This utility model relates to disposable use dispensing needle, belongs to technical field of medical instruments.

Background technology

The employed disposable dispensing needle that uses of units such as present domestic hospital roughly has two kinds: a kind ofly be the inclined-plane pin; Another kind is the side opening pin.Its shortcoming is 1: pin bottle stopper microgranule in piercing process in inclined-plane falls into medicinal liquid easily; 2: the side opening pin has certain distance because of side opening and needle point, causes medicinal liquid residual when making up a prescription.

Summary of the invention

This utility model is the disposable use dispensing needle that designs at the shortcoming of above disposable use dispensing needle existence.Its objective is: preventing that the little material of bottle stopper in the piercing process from coming off enters medicinal liquid; Can take out and use up and shoot away medicinal liquid, reduce residual quantity.

In order to reach above purpose, this utility model by the following technical solutions: on the basis of original disposable use dispensing needle, the needle tubing front end is made the sharp cone of needle point, two inclined holes about having on the cone inclined-plane.

Owing to adopt such scheme, when needle point inserted bottle stopper, tip ramp separated bottle stopper rubber from the hole, and rubber particle is a difficult drop-off; Inclined hole is opened on pin end cone inclined-plane, effectively reduces the medicinal liquid residual quantity in extraction and injection process.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is disposable use dispensing needle sketch map.

Fig. 2 is a partly sketch map of disposable use dispensing needle front end.

1. needle tubings among the figure, 2. needle stand, 3. needle point, 4. needle point cone inclined-plane, 5. two inclined holes on the inclined-plane.

The specific embodiment

With diameter is stainless steel tube about 1.6mm, be cut into the needle tubing (1) of common dispensing needle specification, angle about end both sides of needle tubing (1) are with 38 ° is ground to the needle tubing peak, form two spikes, the reuse particular manufacturing craft closes up two spikes, form needle point (3), inclined-plane (4), beveled aperture (5).With the needle tubing (1) that processes plastics needle stand (2) gummed, become disposable use dispensing needle again with injection molded.

Claims (1)

1. Disposable use dispensing needle partly is made up of needle tubing and needle stand two, it is characterized in that: the needle tubing front end is made the sharp cone of needle point, two inclined holes about having on the cone inclined-plane.
