Detailed Description
Referring to fig. 1 to 6, a cervical and intimal sampler comprises a sampling head 1 and a handle 2, wherein the handle 2 is hermetically screwed with the sampling head 1, and the handle 2 and the sampling head 1 are hollow;
in the invention, the handle part 2 and the sampling head part 1 can also be connected in a plugging mode, and the handle part 2 is communicated with a hollow cavity of the sampling head part 1.
The sampling head part 1 is provided with a through hole 3, a sponge sleeve 4 is sleeved on the through hole 3, a plastic thin sheet belt 6 is spirally wound on the outer side of the sponge sleeve 4, bristles 7 are arranged on the plastic thin sheet belt 6, and two ends of the plastic thin sheet belt 6 are inserted into the sponge sleeve 4 and are extruded on the outer wall of the sampling head part 3 by the inner wall of the sponge sleeve 4; when the sampling device is used, the spiral direction of the plastic sheet belt 6 is the same as the direction of the sampling head 1 which is deeply inserted into the cervical canal to rotate when the sampling device is used, namely the spiral direction of the plastic sheet belt 6 is clockwise when a sample is collected, and then the sampling device also rotates clockwise, so that the two ends of the plastic sheet belt 6 are not taken out by reverse force or the winding is loosened by the reverse force.
An air outlet hole 8 is arranged at the opening of the tail end of the handle part 2, and a sealing cover 9 is clamped on the air outlet hole 8.
Before the invention is used, the sealing cover 9 is clamped on the air outlet 8 and does not seal the air outlet 8, if the sealing is carried out, the air pressure unfavorable blood flows into the hollow cavity of the handle part 2 and the sampling head part 1.
The handle part 2 is made of transparent plastic material.
In the use of the present invention, the blood flowing inside can be observed through the handle 2 made of transparent plastic material.
The through holes 3 of the sampling head 1 are arranged between the intervals formed by spirally winding the plastic sheet belt 6, and when the blood sampling device is used, the plastic sheet belt 6 can conveniently extrude blood into the interior between the intervals formed by spirally winding.
The sealing cover 9 is provided with a clamping column 91 connected with the air outlet hole 8, and the length of two clamping feet 92 when the clamping column is unfolded is larger than the aperture of the air outlet hole 8.
Two clamping feet 92 of a thin blocking piece corresponding to the clamping column are arranged along the hole edge at the inner side of the air outlet hole 8.
In the present invention, the thin blocking piece can block the blocking pin 92 from sliding out of the air outlet hole 8 when the sealing cover 9 is touched without carelessness.
The periphery of the air outlet hole 8 is provided with an auxiliary air outlet hole 82.
The handle 2 and the sampling head 1 can be integrally arranged to replace sealing screwing.
The realization principle of the invention is as follows:
before use, the vagina is opened by a vaginal speculum, and the mucus covering the cervix is wiped off by a cotton swab. Then, the handle part 2 of the sampling device is held by the right hand, the sampling head part 1 is slightly inserted into the cervical canal deeply, the sampling head part contacts with the cervix along the spiral winding direction of the plastic sheet belt 6 and rotates for 5-10 circles, and bleeding occurs in the process.
Blood permeates into the sponge sleeve 4 between intervals formed by spirally winding the plastic thin sheet belt 6, the sponge sleeve 4 is extruded when the handle part 2 rotates and the cervical orifice shrinks, the blood flows into the sampling head part 1 from the through hole 3 arranged on the sampling head part 1 and flows to the handle part 2 communicated with the sampling head part, because the inner diameter of the handle part 2 is not particularly large, and the tail end opening of the handle part is also provided with the air outlet hole 8, the pressure caused by extrusion is continuously pressed into the hollow cavity of the handle part 2, because the handle part 2 is usually made of black materials, the red blood flow can be seen in visible light, if the handle part is made of transparent plastic materials, the condition that the blood flows can be directly seen, the blood can not flow out after 5-10 circles of rotation, the sealing cover 9 is pressed towards the air outlet hole 8 at the moment, two clamping feet 92 of the clamping column 91 on the sealing cover 9 are pressed into the air outlet hole 8, and the hole edge inside the air outlet hole 8 slides out, because the two clamping feet 92 are larger than the aperture of the air outlet hole 8 when being unfolded, the two clamping feet 91 are unfolded after sliding out from the hole edge, and the sealing cover 9 completely shields and seals the air outlet hole 8.
The hollow cavity in the handle 2 now forms a negative pressure, wherein blood cannot flow out and be locked in the cavity. The handle 2 is then removed from the vagina and the speculum is removed.
Referring to fig. 6, at this time, the end 61 of the plastic sheet band 6 inserted into the sponge case 4 is pulled out from the sponge case 4 by tweezers, and unwound from the sponge case 4 to the end 61 in the reverse spiral winding direction, and the whole plastic sheet band 6 is put into a vial containing the cell preservation solution for rinsing, and at this time, the bristles 7 on the plastic sheet band can be sufficiently contacted with the preservation solution because of the plastic sheet band, so that not only the number of times of rinsing is less than that of the conventional one, but also the collected cell sample is sufficient. Finally, the name and the sample number are marked on the bottle body as in the conventional process.
After the endocervix is sampled, the sponge sleeve 4 and the plastic thin sheet belt 6 can be taken down together, because the endocervix can be congested in the cervix or blocked by purulent secretion, most of the secretion can be mixed on the plastic thin sheet belt 6 if the endocervix is detected, and the other part of the secretion is melted into the sponge sleeve 4 along with blood, but the blood can easily enter the cavity from the sponge hole, so the sponge sleeve 4 and the plastic thin sheet belt 6 can be taken down together for the secretion detection, and if the secretion is not much, the plastic thin sheet 6 only needs to be taken down.
