Description

Cervical sampler

Technical Field

The utility model relates to an utensil for examining women's uterus cervix, particularly, relate to a cervix sample thief.

Background

In medical pathological examination, liquid-based thin-layer cytology is gradually used as the main method for detecting gynecological cervical cancer. The key of the liquid-based thin-layer cytology detection technology lies in the collection of cells, cervical cells are collected by a cervical sampling brush and then rinsed into a cell preservation liquid bottle, and the cell preservation liquid in the bottle can fully fix the cells, digest partial mucus proteins, dissolve red blood cells and kill microorganisms. A cervical sampler is used to sample the patient during cell collection.

The existing cervical sampler is a cervical brush, but has a single function, and the cervical brush and the illuminator are not of an integrated structure, so that the cervical brush is often easily shielded in the process of collecting cells, and a doctor cannot clearly observe the positions for examination and sampling; and requires the cooperation of two persons to complete the sampling.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a cervical sampler with a light source is provided.

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

the cervix sampler comprises a supporting rod, an illuminator and a sampling piece for collecting cervical secretions, wherein the illuminator comprises an annular outer shell, an annular inner shell and a lamp source assembly, the lamp source assembly is provided with a plurality of lamp beads which are annularly arranged, the annular outer shell is arranged on the outer side of the lamp source assembly, the annular inner shell is arranged on the inner side of the lamp source assembly, the bottom of the annular outer shell is connected with the bottom of the annular inner shell through a bottom plate, and the top of the annular outer shell is connected with the top of the annular inner shell through a first convex lens; inside branch one end telescopic inserted annular inner shell, the branch other end stretches out outside the annular inner shell and is connected with the sample piece, is connected with the fastener that is used for fastening the illuminator between annular inner shell and the branch.

As a further improvement of the above technical solution:

and a second convex lens is arranged between the annular outer shell and the annular inner shell and is positioned between the lamp source assembly and the first convex lens. The light that the lamp source subassembly was launched is once assembled through second convex lens and first convex lens and is launched, and the light that the lamp source subassembly was launched is launched more through first convex lens to the second convex lens that newly increases, improves the luminous utilization ratio of lamp pearl.

Furthermore, the light incident surfaces of the first convex lens and the second convex lens are both concave curved surface revolution bodies, and the light emergent surfaces are both convex curved surface revolution bodies. The light emitted by more light source components can be gathered, and the brightness of the illuminator is improved.

Furthermore, the sampling part comprises a supporting plate and a brushing body arranged on the supporting plate, and the top of the brushing body is in a circular arc shape suitable for the shape of a cervical orifice. The brush body is composed of a plurality of rows of soft brush hairs, and the arc shape is formed by the way that the plurality of rows of soft brush hairs are gradually shortened from the middle part of the support plate to two sides. The lengths of the bristles are different, and the tops of the bristles are made into a shape which is gradually shortened from the middle part of the supporting plate to two sides in a circular arc shape so as to adapt to the shape of the cervical orifice, so that the contact area between the bristles and the cervical orifice is increased as much as possible, and the accuracy and the reliability of sampling are ensured.

The fastener is the sleeve, and the sleeve cover is located on branch and rather than threaded connection, and after branch is flexible, the sleeve inserts in the annular inner shell and rather than threaded connection. The illuminator can be detachably connected with the supporting rod, so that the sampling piece can be conveniently taken away and inspected, and the illuminator can be conveniently reused.

Compared with the prior art, the utility model has the advantages that:

1. the lamp source component is provided with a plurality of lamp beads which are arranged in an annular mode, light is emitted around the sampling piece, the situation that the light is shielded by the supporting rod is avoided, and an operator can clearly observe positions of inspection and sampling.

2. The lamp source subassembly is through first convex lens emission light, and the light that the lamp source subassembly was launched after assembling via first convex lens, improves the luminous utilization ratio of lamp source subassembly, guarantees that light is sufficient, and the operator can more clearly observe the position of inspection and sample.

3. Inside branch one end telescopic inserted annular inner shell, be convenient for adjust the length that the sampling piece stretched into the vagina, improved the accuracy of inspection result.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the following detailed description of the present invention, taken in conjunction with the accompanying drawings and the detailed description, is given in a non-limiting manner.

As shown in fig. 1 and fig. 2, the cervical sampler of the present embodiment includes a supporting rod 3, an illuminator 1 and a sampling member 4 for collecting cervical secretions, the illuminator 1 includes an annular outer shell 12, an annular inner shell 13 and a lamp source assembly 11, the lamp source assembly 11 has a plurality of lamp beads arranged in an annular shape, the annular outer shell 12 is disposed outside the lamp source assembly 11, the annular inner shell 13 is disposed inside the lamp source assembly 11, the bottom of the annular outer shell 12 is connected with the bottom of the annular inner shell 13 through a bottom plate 14, and the top of the annular outer shell 12 is connected with the top of the annular inner shell 13 through a first convex lens 16; inside branch 3 one end telescopic inserted annular inner shell 13, the branch 3 other end stretches out annular inner shell 13 outside and is connected with sample piece 4, is connected with the fastener 2 that is used for fastening illuminator 1 between annular inner shell 13 and the branch 3. The fastener 2 is a sleeve, the sleeve is sleeved on the support rod 3 and is in threaded connection with the support rod 3, and after the support rod 3 stretches out and draws back, the sleeve is inserted into the annular inner shell 13 and is in threaded connection with the annular inner shell.

Wherein, a second convex lens 15 is arranged between the annular outer shell 12 and the annular inner shell 13, and the second convex lens 15 is positioned between the lamp source assembly 11 and the first convex lens 16. The light incident surfaces of the first convex lens 16 and the second convex lens 15 are both concave curved revolution bodies, and the light emergent surfaces are both convex curved revolution bodies. The sampling member 4 includes a support plate 41 and a bristle body 42 disposed on the support plate 41, and the top of the bristle body 42 is in a circular arc shape suitable for the shape of the cervical orifice. The bristle body 42 is composed of a plurality of rows of soft bristles, and the arc shape is formed by the rows of soft bristles gradually shortening from the middle part of the support plate 41 to two sides.

For the use of this example, reference is made to the following steps:

firstly, the light source assembly 11 in the illuminator 1 is turned on, and the light emitted by the light source assembly 11 is converged twice by the first convex lens 16 and the second convex lens 15 and then emitted out, so that the illumination is clear, and the sufficiency of the light source is ensured. Then, the operator holds the outer wall of the ring-shaped housing 12 by hand, inserts the bristle body 42 into the cervix, and rotates the rod 3 to rotate the bristles in the cervix, leaving more endocervical cells on the bristles. Finally, the rotating sleeve takes out the rod 3 containing the sample piece 4 and sends it to inspection.
