Abstract

The utility model discloses a pencil for marking with circle for immunoassay, which comprises a pencil body, a pencil mouth, a pencil nib, an outer sleeve positioned in the pencil body, an inner sleeve, a pencil inner nib and a compression spring. The pencil nib is oppressed, so the pencil inner nib is slid, and a lug boss which is arranged on the pencil inner nib and matched with the inner sleeve in a sealing mode moves. The liquid in the pencil body passes through liquid inlet holes on the outer sleeve and flows out through the inner sleeve and the pencil mouth. The utility model is used for dyeing immunoassay. The pencil nib of the utility model is oppressed to draw a circle on a slice, so that reagent dripped on the slice does not flow out of the circle. In this way, the reagent is saved, and the solution in the pencil is also saved. The utility model has the advantage of convenient use.

Description

Immunohistochemistry labeled pen

The utility model relates to a kind of immunohistochemistry labeled pen.

Do immunohistochemical staining in medical treatment, health, scientific research, during molecular hybridization in situ, normally reagent is dropped in the section, an inclination will make reagent run off if cut into slices slightly.Existing a kind of solution can stop reagent to flow, but solution is coated onto tends to inhomogeneously in the section with dipping in the method for getting, and use is very inconvenient.

The purpose of this utility model provides a kind of easy to use, draws the uniform immunohistochemistry labeled pen of circle.

Main technical schemes of the present utility model is: include handwriting, with the mouth of handwriting by being threaded, the nib that can in a mouth, slide, handwriting is an open cavity, the overcoat of hollow inserts handwriting from opening part, interior cover inserts overcoat, interior cover, overcoat, be sealed and matched between the handwriting, there is inlet opening that handwriting is communicated with overcoat inside on the sidewall of overcoat, pen inner point can slide in the through hole of interior cover and in the overcoat and be coaxial with nib, there is front fine and rear thick taper type boss at the pen inner point middle part, and boss and interior cover are sealed and matched, and between the endoporus step of boss and overcoat compression spring are arranged.

During use, the compressing nib, promote pen inner point, make between boss on the pen inner point and the interior cover and the gap occurs, solution in the handwriting enters overcoat through inlet opening, through hole, a mouth through the gap of boss and interior inner room, interior cover flow out, so just can in section, draw circle, and the flow size of solution is controlled by the nib pressure, when loosening nib, compression spring can prevent the pen inner point pushed home that again solution flows out, and the utility model uses very convenient, draw circle evenly, and save reagent and draw circle solution.

Fig. 1 is the structural drawing of a kind of embodiment of the utility model.

As shown in Figure 1, the utility model comprises handwriting 1, the nib 3 that can in a mouth, slide by a mouth 2 that is threaded with handwriting 1, handwriting 1 is an open cavity, the overcoat 6 of hollow inserts handwriting 1 from opening part, interior cover 5 inserts overcoats 6, interior cover 5, overcoat 6, be sealed and matched between the handwriting 1, there is inlet opening 8 that handwriting 1 is communicated with overcoat 6 inside on the sidewall of overcoat 6, pen inner point 4 can slide in the through hole 51 of interior cover 5 and in the overcoat 6 and be coaxial with nib 3, there is front fine and rear thick taper type boss 41 at pen inner point 4 middle parts, and boss 41 is sealed and matched with interior cover 5, between the endoporus step 61 of boss 41 and overcoat 6 compression spring 7 is arranged.
