Abstract

The utility model discloses a disposable slot-type skin pricking needle, which comprises a needle head and a limit column; wherein, the limit column is a trapezoid column arranged on a back end of the needle head, a handle is connected on the back end of the limit column and the handle is disposed on the needle groove; because an end face of the limit column has large contact area with the tested skin, the depth of a needlepoint puncturing to the skin can be limited effectively, so as to ensure the testing effect; meanwhile, the needle groove is positioned on the handle, the medical staff can grasp the depth of pricking easily, and accordingly the operation is convenient and the tested person feel less pain. The device has simple structure and is easy for making, so that the material cost and the production cost can be greatly reduced.

Description

Disposable slot type skin points pricker

Technical field

This utility model relates to a kind of some pricker that is used for tuerculoderma, belongs to the medical equipment technical field.

Technical background

Tuerculoderma is that allergy is clinical in one of the most frequently used method of test specificity sensitizer, and its test method mainly contains intradermal test and pricking method test.Because that pricking method test has is simple to operate, safety, economy, progressively replaces intradermal test clinically and become conventional skin test method.

British patent GB2317113A discloses a kind of skin allergy test bar, and needle point adopts 6 pyrometric cone points of annular arrangement, and the heart is provided with slightly short than the needle point tiny flat-nosed cylinder of length therein, and this cylinder can play the effect that the restriction needle point thrusts skin depth.But its structure and manufacturing process relative complex, cost is higher: the wound that thrusts in addition behind the skin is more relatively, might make patient excessive to the antigen test reaction.

The utility model content

The purpose of this utility model provides a kind of single-use skin point pricker that is suitable for clinical tuerculoderma special use, make this skin points pricker can effectively control the thrust weight of syringe needle, have the low and characteristics easy to use of simple in structure, manufacturing cost again skin.

This utility model is achieved by the following technical solution: a kind of single-use skin point pricker, comprise syringe needle, and it is characterized in that being provided with limited post in the rear end of syringe needle.

Described limited post adopts trapezoidal column, and its rear end is connected with handle, and this handle is that the cross section is orthogonal laminated structure, and needle tray is arranged in the middle of the handle.

After adopting this structure, because syringe needle is positioned at the front end of limited post, the end face of limited post and tested skin have bigger contact area, limit the effect that syringe needle thrusts the skin weight thereby played well, have guaranteed the test effect effectively; Owing to be provided with needle tray in the middle of the handle, be very easy to grasp the pricking method degree of depth when test medical worker is used, and do not rely on tester's experience and feel, easy to use, testee's misery is little.This skin prick needle construction is simple simultaneously, is easy to processing and manufacturing, therefore effectively reduces production cost.

Fig. 1 is the unilateral sketch map of a kind of embodiment of this utility model disposable slot type skin points pricker.

Fig. 2 is the schematic three dimensional views of a kind of embodiment of this utility model disposable slot type skin points pricker.

The specific embodiment

Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.

Disposable slot type skin points pricker limited post front end shown in Figure 1 is a syringe needle 1, and this syringe needle is that one-shot forming becomes an integral body with limited post and handle, and syringe needle adopts the triangular pyramid point, and the length of syringe needle should meet medical science tuerculoderma standard-required; Limited post 2 is for adopting the trapezoidal column structure, and its rear end is connected with handle 3, and this handle is that the cross section is orthogonal laminated structure, in the middle of the handle needle tray 4 is arranged, and plays anti-skidding effect, so that the operator is hand-held and operation.Described limited post 2, handle 3 are one with needle tray 4, have both played position-limiting action, can make handle again and use.The sectional area of limited post is 80～160 times of syringe needle maximum secting area: the material of syringe needle, limited post, needle handle is medical stainless steel.Every some pricker is disposable use, avoids the human body cross infection.

Claims (4)

1. a disposable slot type skin points pricker comprises syringe needle (1), and it is characterized in that: be provided with limited post (2) in the rear end of syringe needle, described syringe needle and limited post are structure as a whole.

2. according to the described disposable slot type skin points pricker of claim 1, it is characterized in that: described limited post (2) is trapezoidal column, and its rear end is connected with handle [3], and this handle is that the cross section is orthogonal laminated structure.
