This device is used in inspection of internal medicine sense of pain simple structure, convenient to use can guarantee to inspect that the overdraft of the sense of pain is unanimous at every turn, and it is even to make the power of at every turn pierceing say.

Description

A kind of internal medicine pain sensation inspecting device

Technical field

This utility model belongs to medical apparatus and instruments device technique field, is specifically related to a kind of internal medicine pain sensation inspecting device。

Background technology

The pain sensation gently stings patient skin typically by the needle point of pin with uniform strength, allows patient state concrete impression immediately。In order to avoid subjective or Suggestion, patient should close order acceptance test。Note the comparison at lateral symmetry position during test, after inspection, record type (normal, allergy, go down, disappearance etc.) and the scope of sensory disturbance。But directly gently sting the skin of patient with pin, the bad assurance of dynamics, it is necessary to design a kind of special examination apparatus device。

Utility model content

The purpose of this utility model is for above-mentioned the deficiencies in the prior art, it is provided that one can make the uniform internal medicine pain sensation inspecting device of the dynamics of thrusting。

The purpose of this utility model is achieved through the following technical solutions。

A kind of internal medicine pain sensation inspecting device, including pushing shank and syringe needle, the lower end of described pushing shank is connected to syringe needle, also include base plate and hands handle, the middle part of described base plate is provided through the sleeve pipe of base plate, the two ends of described base plate are fixedly connected with symmetrically arranged first hound and the second hound, the top of described first hound and the second hound is all fixing with the outer wall of sleeve pipe to be connected, the upper end of described pushing shank is connected with handle, the lower end of described pushing shank extend in sleeve pipe, the lower ending opening of described sleeve pipe protrudes inwardly from formation stop block, it is provided with spring between described pushing shank and stop block, described syringe needle is positioned at spring, the needle outlet being provided centrally with confession syringe needle traverse of described stop block。

Further, described spring is helical spring。

Further, described spring in the raw time length is needle length 1/2nd。

Further, described spring in the raw time, the tip of described syringe needle flushes with the lower surface of base plate。

This utility model produces to provide the benefit that owing to taking above-mentioned technological means: internal medicine pain sensation inspecting device simple in construction of the present utility model, easy to use, by arranging handle and the pushing shank being connected with handle, push and between shank and stop block, spring is set, owing to the coefficient of elasticity of spring is definite value, the compression travel of spring is also definite value, ensure that the downforce every time checking the pain sensation is consistent, make the power every time thrust uniform。

Accompanying drawing explanation

Fig. 1 is the structural representation of internal medicine pain sensation inspecting device of the present utility model。

In figure, 1-base plate, 2-the first hound, 3-the second hound, 4-sleeve pipe, 5-handle, 6-pushes shank, 7-syringe needle, 8-spring, 9-stop block, 10-needle outlet。

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is described in further detail。Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model。

Internal medicine pain sensation inspecting device of the present utility model is as shown in Figure 1, including pushing shank 6 and syringe needle 7, the lower end pushing shank 6 is connected to syringe needle 7, also include base plate 1 and handle 5, the middle part of base plate 1 is provided through the sleeve pipe 4 of base plate 1, the two ends of base plate 1 are fixedly connected with symmetrically arranged first hound 2 and the second hound 3, the top of the first hound 2 and the second hound 3 is all fixing with the outer wall of sleeve pipe 4 to be connected, the upper end pushing shank 6 is connected with handle 5, the lower end pushing shank 6 extend in sleeve pipe 4, the lower ending opening of sleeve pipe 4 protrudes inwardly from formation stop block 9, push and be provided with spring 8 between shank 6 and stop block 9, spring 8 is helical spring, syringe needle 7 is positioned at helical spring 8, spring 8 in the raw time length is syringe needle 7 length 1/2nd, the needle outlet 10 being provided centrally with confession syringe needle 7 traverse of stop block 9, when spring 8 is not stressed, the tip of syringe needle 7 flushes with the lower surface of base plate 1。

The work process of internal medicine pain sensation inspecting device of the present utility model: the operating physical force of examiner passes sequentially through handle 4, pushes shank 6, spring 8, syringe needle 7 are delivered to patient skin, and the downforce of patient skin is equal to the elastic force of spring 8。Owing to coefficient of elasticity and the compression travel of spring 8 are definite value, therefore can drawing, the elastic force of spring 8 is definite value, can ensure that the downforce of inspection every time is identical。Needs according to clinical examination can select the spring of different coefficient of elasticity。

Internal medicine pain sensation inspecting device simple in construction of the present utility model, easy to use, by arranging handle 4 and the pushing shank 6 being connected with handle 4, push and between shank 6 and stop block 9, spring 8 is set, owing to the coefficient of elasticity of spring 8 is definite value, the compression travel of spring 8 is also definite value, ensure that the downforce every time checking the pain sensation is consistent, make the power every time thrust uniform。

Embodiment described above only have expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to this utility model the scope of the claims。It should be pointed out that, for the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these broadly fall into protection domain of the present utility model。Therefore, the protection domain of this utility model patent should be as the criterion with claims。
