Abstract

The utility model relates to a novel disposable lumbar spinal needle, which belong to the field of medical equipment, is formed by a needle bar 1, a needle handle 2, a tee pipe 3, a needle core 4, a pressure measuring hose 5 and a limiter 6, and is characterized in that the limiter 6 is arranged on the needle bar 1, the tail end of the needle handle 2 is connected with the tee pipe 3 of which the tail end is connected with the needle core 4, and the opening at the other end of the tee pipe 3 is connected with the pressure measuring hose 5. The novel disposable lumbar spinal needle is disposable in use, simple in structure and convenient to use, is an ideal disposable lumbar spinal needle, dose not need to pull or connect a pipe in the lumbar puncturing process of a patient, can visually measure the dynamic change process of cerebrospinal fluid pressure and effectively avoids medical accidents caused by the moving of the puncture needle after the successful lumbar puncturing, thus ensuring the medical safety of the patient.

Description

The new disposable lumbar puncture needle

Technical field: this utility model belongs to medical instruments field, and particularly a kind of replace tubes that do not need is taken over, and can measure the dynamic changing process of cerebrospinal pressure intuitively, effectively avoid puncture needle to move, simple in structure, easy to use, disposable new disposable lumbar puncture needle.

Background technology: waist is worn art and is used very extensive in the diagnosis of Neurology Department disease and treatment, at present, the lumbar puncture needle that uses clinically directly connects glass tubing after as needle tubing and punctures, in use need two people's compounding practices, and replace tubes and adapter repeatedly, very loaded down with trivial details, in a rush especially when high cranium aluminium hydraulic pressed connecting pipe occurring, and, in this process, can not observe the dynamic change of cerebrospinal fluid at any time, cause the formation of patient's cerebral hernia easily, after waist is worn successfully, because the fixture that there is no need, in adapter and replace tubes process, lumbar puncture needle is shifted easily, cause puncture failure, bring unnecessary loss and misery to the patient.

Summary of the invention: the purpose of this utility model is to provide a kind of replace tubes that do not need to take over, and can measure the dynamic changing process of cerebrospinal pressure intuitively, effectively avoids puncture needle to move, and is simple in structure, easy to use, disposable new disposable lumbar puncture needle.

For achieving the above object, this utility model has been taked following technical scheme: this new disposable lumbar puncture needle, constituted by shank, needle handle, tee T, nook closing member, pressure measurement flexible pipe and stop, shank is provided with stop, the end of needle handle connects tee T, the end of tee T connects nook closing member, and the other end opening of tee T is connected with the pressure measurement flexible pipe.

This utility model, be disposable use, simple in structure, easy to use, for carrying out waist, the patient passing in the journey, do not need replace tubes to take over, and can measure the dynamic changing process of cerebrospinal pressure intuitively, after waist is worn successfully, effectively avoided puncture needle to move and the malpractice that causes, having ensured patient's medical safety, is a kind of desirable disposable lumbar puncture needle.

Description of drawings: the utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is structural representation of the present utility model.

With reference to accompanying drawing 1,1, shank, 2, needle handle, 3, tee T, 4, nook closing member, 5, the pressure measurement flexible pipe, 6, stop.

The specific embodiment: this utility model, constituted by shank 1, needle handle 2, tee T 3, nook closing member 4, pressure measurement flexible pipe 5 and stop 6, shank 1 is provided with stop 6, the end of needle handle 2 connects tee T 3, the end of tee T 3 connects nook closing member 4, and the other end opening of tee T 3 is connected with pressure measurement flexible pipe 5.

During use this utility model, earlier pressure measurement flexible pipe 5 is connected with pressure gauge, carries out the lumbar puncture art according to operating routine for the patient then, after waist is worn successfully, with stop 6 fixed-site of shank 1 is lived, nook closing member 4 is taken out, and the connection winding the needle tube gets final product.
