Background

The pathology is a basic medical science for researching the cause, the generation mechanism and the development rule of human diseases and the morphological structure, the functional metabolic change and the pathological change of organisms in the disease process, and a plurality of devices for pathological cell examination are commonly used at present, particularly gynecological examination is common. Wherein, a sampling device for cytopathology examination with patent number CN201821202688.1, through setting up spring, inner tube and outer tube, when the utility model is pulled out after sampling, the clamp plate can be returned to the original position under the action of spring force, the clamp plate can drive the brush holder to move back, the brush head and the brush hair at the upper end of the brush holder retract, the brush holder drives the shell flap to close while moving back, thereby the brush head and the brush hair after sampling are protected effectively by the shell flap, the contact between the brush head and the brush hair and the vaginal wall is avoided completely, the problem that the brush head and the brush hair are polluted by other secretions of the vaginal wall is solved; although the problem of pollution is solved, the collecting effect is general, the structure is complex, and the comfort of a patient is easy to get pain.

SUMMERY OF THE UTILITY MODEL

For solving the problem that the background art exists, the utility model provides a pathological cytology inspection sampling device can gather the sample more effectively, and simple structure easily operates, and the travelling comfort is good.

In order to solve the technical problem, the utility model provides a following technical scheme:

the utility model relates to a pathological cytology examination sampling device, including the guiding tube, the inside lumen of guiding tube is equipped with the screw hole, has the push rod through the screw hole spiro union in the guiding tube, and the front end of push rod is equipped with the screw thread chamber, and screw thread chamber front end spiro union has the sampling head, and the outside of guiding tube is equipped with the rubber ball, and the front end of rubber ball is equipped with the roll-up opening, and the roll-up opening is rolled up to the back, and the rear end of rubber ball is fixed to be equipped with the nut, and the nut realizes dismantling of rubber ball through the screw thread looks spiro union that is equipped with the guiding tube outside, and the front end surface of sampling head is equipped with the spiral line.

Furthermore, the rubber ball is ellipsoidal as a whole.

Further, the diameter of the scroll opening is larger than the diameter of the guide tube.

Furthermore, the surface of the sampling head in the range of the spiral threads is provided with a rough surface made of silica gel.

Further, the inner pipe diameter of the front end of the guide pipe is larger than the maximum diameter of the sampling head.

Compared with the prior art, the utility model discloses following beneficial effect has: this kind of pathological cytology inspection sampling device, through setting up detachable rubber ball and be equipped with the roll form opening at the rubber ball front end, can realize the roll up and the closing of roll nature front end when passing in and out the vagina, the protection sampling head is not contaminated to through setting up the screwed guiding tube of inner chamber, make it can twist slowly through the screw thread and guide the sampling, prevent hard too big, through setting up detachable sampling head and set up the spiral line at the sampling head front end and be convenient for gather the sample.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1-2, a pathological cytology examination sampling device, including guiding tube 4, the inside lumen of guiding tube 4 is equipped with screw hole 8, there is push rod 5 through 8 spiro couplings of screw hole in guiding tube 4, the front end of push rod 5 is equipped with

screw cavity

7, 7 front end spiro couplings of screw cavity have sampling head 1, the outside of guiding tube 4 is equipped with rubber ball 2, rubber ball 2's front end is equipped with roll shape opening 6, roll shape opening 6 turns over the book to the rear, rubber ball 2's rear end is fixed and is equipped with nut 3, nut 3 realizes dismantling of rubber ball 2 through the screw thread looks spiro union that is equipped with guiding tube 4 outside, the front end surface of sampling head 1 is equipped with spiral line 9, scrape through its special helicla texture and get the sample.

Wherein, the rubber ball 2 is ellipsoidal as a whole, and is convenient for entering and exiting the vagina to play a role of pollution prevention through the soft characteristic of the rubber ball to sample a sample.

Wherein, the diameter of the scroll opening 6 is larger than that of the guide tube 4, which is convenient for the installation and the disassembly of the rubber ball 2.

Wherein, the sampling head 1 surface in the range of the spiral line 9 is equipped with the rough surface of silica gel material, does benefit to the existence of sample, avoids the sample to drop from sampling head 1 surface in the short time.
