The utility model discloses still relate to a sampling subassembly that contains above-mentioned sample thief and save the container.
Background
Cervical cell sampling is a preliminary step for detecting whether a person to be sampled has a disease such as cervical infection.
At present, cervical cell collection is usually completed by professional personnel such as doctors and nurses in professional places such as hospitals and medical stations. However, this operation is likely to cause discomfort to the person being sampled. Even some sampled persons refuse to test because they do not want to be overexposed to outsiders. Or some of the sampled persons may not go to the hospital for cell collection because of the residence at a distance from the hospital or the body of the person. For these sampled persons, hospital samplers are usually given to them for their own home or for sampling by relatives (this is known in the art as "self-sampling"). The collected samples are sent to hospitals for relevant detection.
However, there are currently no cervical cell sampling devices available exclusively for sampling. The sampler for hospitals is difficult to be used by a sampler without special training (especially a self-sampler with low education level) and is inconvenient to be used. The problems of sampling failure or sample pollution caused by wrong use mode and non-standard use mode often occur. In this case, not only the detection effect may be inaccurate, but also resources may be wasted. In addition, in hospitals, the cell samples collected by the sampler are directly placed in a preservation solution for preservation and subsequent detection. However, for self-collection which is not performed in a hospital, the problems of insufficient sample elution, difficulty in transportation, liquid leakage, contamination, and the like are easily caused when a cell sample is placed in a preservation solution and then sent to the hospital for detection. These problems also cause great inconvenience in the collection and storage of the sample.
Therefore, there is a need for a sampling device that can conveniently achieve self-sampling of cervical cells.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
The sampling assembly of the present invention may include a downsampler 100 and a preservation container 200 for enabling self-sampling of cervical cell samples.
Fig. 1-2 show one embodiment of a sampler 100 according to the present invention.
As shown in fig. 1, the sampler 100 includes a cylindrical housing 110, which may be configured as a hollow cylinder. A sampling opening is configured at the lower end of the cylindrical housing 110. The sampler 100 further includes a sampling rod 120 disposed within the cylindrical housing 110. The longitudinal axis of the sampling rod 120 is parallel to or overlaps the longitudinal axis of the cylindrical housing 110. At the lower end of the sampling rod 120, a sampling head 122 is configured for contact with the cervix for taking a sample of cervical cells. In the initial state, the sampling head 122 is within the cylindrical housing 110, enclosed and protected as shown in fig. 1. In use, the sampling rod 120 is movable along the longitudinal axis of the cylindrical housing 110 such that the sampling head 122 protrudes from the sampling opening at the lower end of the cylindrical housing 110 for sampling.
In a preferred embodiment, the sampling head 122 has a trapezoidal cross-section as shown in FIG. 1. That is, the sampling head 122 may be configured as a circular truncated cone. The larger bottom surface of the truncated cone shape forms the lower end surface 122A of the sampling head 122. The lower end surface 122A is formed as a sampling surface for contacting the cervix to collect cervical cells. The sampling head 122 here takes this form so that the sampling surface is a large-area plane. This advantageously increases the contact area between the sampling surface and the cervix, thereby facilitating the acquisition of a sufficient sample by a user without having to perform any major training (e.g. stirring the sampler, etc.) and thus ensuring, on the one hand, the accuracy and validity of the test results and, on the other hand, avoiding injury to the person being sampled. In addition, the shaped sampling head 122 allows the sampling surface thereof to contact the sample collection portion 203 (described in more detail below) of the holding container 200 with a relatively uniform force to ensure that the sample is evenly and efficiently applied to the sample collection portion 203.
In a preferred embodiment, the sampling head 122 is constructed to be flexible, such as made of medical grade cotton. In this case, the sampling head 122 is prevented from being damaged when it is brought into contact with the cervix. In addition, it is also advantageous to smear the sample on the sampling head 122 onto the sample collection portion 203. Additionally, in a preferred embodiment, the sampling head 122 is flexible and has limited flexibility. Thus, after a sampling process is completed (particularly after the sample on the lower end surface 122A is smeared on the sample collection portion 203 of the preservation container 200), the sampling head 122 is deformed significantly and cannot be used any more. The user can easily tell if the sampling head has been used and can no longer use the sampling head 122. The sampling head 122 (or even the entire sampler 100) is disposable, and can effectively avoid the problems of pollution and the like caused by multiple uses.
In the exemplary embodiment shown in fig. 1, a radially outwardly projecting latching ring 121 is formed on the sampling rod 120. In addition, a radially inwardly extending fastening plate 111 is formed in the cylindrical housing 110. The fixing plate 111 is located on the lower side of the snap ring 121 (i.e. closer to the sampling opening) with an elastic member (e.g. a coil spring) 130 disposed therebetween. This configuration allows the sampling rod 120 and sampling head 122 to remain in place in a normal state (i.e., the sampling head 122 is within the cylindrical housing 110).
The upper end 120A of the sampling rod 120 extends upwardly and out from the upper end of the cylindrical housing 110. In this case, the user can extend the sampling head 122 from the sampling opening by pushing on the upper end 120A of the sampling rod 120. Preferably, a scale is provided at the upper end 120A to facilitate the length over which the user and the person being sampled will grasp the sampling head 122. This can effectively relieve the psychological stress of the user and the person to be sampled. In particular, the scale at the upper end 120A is easy to read, and is very suitable for the sampled person to operate and read by himself.
In a preferred embodiment, a manipulation protrusion 124 is provided at a side portion of the sampling rod 120 within the cylindrical housing 110, and the manipulation protrusion 124 extends through a manipulation hole 110A formed in a side wall of the cylindrical housing 110 to extend outside the cylindrical housing 110 so as to be touched and manipulated by a hand of a user. As shown in fig. 1, the operation hole 110A is a long and narrow hole extending along the axial direction of the cylindrical housing 110. Thus, the user can move the manipulating protrusion 124 along the manipulating hole 110A, so that the sampling rod 120 and the sampling head 122 can move together along the axial direction of the cylindrical housing 110, and the sampling head 122 can be extended. The user can toggle the manipulation protrusion 124 and make a reading through the scale at the upper end 120A of the sampling rod 120. The arrangement mode can effectively avoid the limb of the user from shielding the scales.
In addition, as shown in fig. 2, one or more positioning holes 110B communicating with the operation hole 110A and extending laterally with respect to the operation hole 110A are also configured on the cylindrical housing 110. The manipulation protrusion 124 can enter each positioning hole 110B and be locked in the axial direction of the cylindrical housing 110. The respective positioning holes 110B are spaced apart from each other in the axial direction of the cylindrical housing 110, defining a plurality of different gear positions. These gears define different lengths of the sampling head 122 extending out of the sampling opening, respectively.
For example, the manipulation protrusion 124 may be initially located in the uppermost "0 th" positioning hole shown in fig. 2. At this time, the sampling head 122 is within the cylindrical housing 110 and is restricted from protruding. This can effectively prevent the sampler 110 from being misoperated. When using the sampler 110, the user can manually dial the manipulation protrusion 124 into the manipulation hole 110A and dial the manipulation protrusion 124 downward to extend the sampling head 122. When the manipulation protrusion 124 moves to a position opposite to the positioning hole 110B of the "1 st" position, the user can dial the manipulation protrusion 124 into the positioning hole 110B of the "1 st" position, and make the person to be sampled feel whether the sampling head has contacted the cervix. If the cervix has been contacted, indicating that sampling has been successful, the entire sampler 100 may be removed. If the cervix is not touched, the manipulation protrusion 124 can be shifted into the manipulation hole 110A again, and the manipulation protrusion 124 can be shifted downwards to be positioned in the positioning holes 110B such as the "2 nd" positioning hole, the "3 rd" positioning hole and the like, so that the person to be sampled can sense whether the sampling head touches the cervix again.
The structure and the operation mode are very beneficial to the palm holding condition of the user and the person to be sampled, and the psychological pressure of the user and the person to be sampled can be greatly relieved. In addition, the sampling rod 120 and the sampling head 122 can also be rotated by laterally shifting the manipulation protrusion 124 at the positioning hole 110B. On the one hand, such rotation facilitates the person being sampled to accurately sense the position of the sampling head 122 within the body. On the other hand, this enables the lower end surface 122A of the sampling head 122 to be slightly rotated at the cervix when the sampling head 122 contacts the cervix, so that a sample of cervical cells can be more conveniently and efficiently collected.
Further, it is preferable that, as shown in fig. 1 and 2, a stopper 140 extending radially outward is provided on an outer side wall of the cylindrical housing 110. The flap 140 extends in a direction substantially perpendicular to the longitudinal axis of the cylindrical housing 110. In use, the user may insert the sampler 100 into the vagina of a person to be sampled until the flap 140 contacts the body of the person to be sampled. The sampling head 122 is then extended. The baffle 140 can ensure that the sampler 100 is inserted to a proper depth, so that the situation that the sampler 100 is inserted too deeply to hurt the person to be sampled and the situation that the sampler 100 is inserted too shallowly to fail in sampling can be avoided.
Fig. 3 schematically illustrates one embodiment of a preservation container 200 according to the present invention.
The holding container 200 includes a container main body 201. The container body 201 can be designed, for example, in a cylindrical or cubic manner. A receiving hole is formed in the container body 201, and the receiving hole extends to the upper end surface of the container body 201 to form an opening. A sample collection portion 203 is provided at the bottom of the accommodation hole. The sampler 100 may be inserted into the receiving hole through the opening. At this time, the lower end surface 122A of the sampling head 122 may contact the sample collection portion 203, such that the sample of cervical cells on the lower end surface 122A is transferred onto the sample collection portion 203. Here, the user can more effectively smear the sample on the sample collection part 203 by pressing, rotating the sampler 100, and the like. The side wall of the accommodation hole forms a guide surface of the sampler 100, thereby defining a movable range of the sampler 100. For example, so that the sampler 100 cannot translate within the receiving hole. Therefore, the problems of ' coating wrong position ', coating out of a circle ' and the like can not be caused, and the collected sample can be effectively utilized in detection.
Preferably, a cover 204 is formed extending upward at the upper end of the container main body 201. The lid 204 is hinged to the container body 201. In the storage state, or after the sample is collected on the sample collection portion 203, the cover 204 may be turned down so that the accommodation hole is covered to prevent the sample from being contaminated. The surface of the cover 204 facing the receiving hole may be printed with instructions for use, etc., so that the user can easily see how the sampler 100 and the storage container 200 are used when the cover 204 is standing up with respect to the container body 201. When the cover 204 covers the opening of the receiving hole in the container body 201, the cover 204 and the container body 201 may be connected together by, for example, a snap-fit connection.
In a preferred embodiment, an internal thread 202 is formed on the inner side wall of the receiving hole of the container body 201; correspondingly, a matching external thread 112 is formed on the outer side wall of the cylindrical housing 110 of the sampler 100. Thus, the user can insert the sampler 100 into the receiving hole of the container main body 201 by rotating the sampler 100. This is beneficial to ensure that the lower end surface 122A of the sampling head 122 is aligned with the sample collection part 203, and avoids the problem of sample collection failure caused by shaking hands, force application errors and the like. After the sampler 100 is inserted to the bottom of the receiving hole such that the lower end surface 122A of the sampling head 122 is in contact with the sample collection portion 203, the user may further rotate the sampler 100 (e.g., 3-5 turns) such that the lower end surface 122A of the sampling head 122 is more tightly against the sample collection portion 203 and relatively rotates with respect to the sample collection portion 203. This is more advantageous for guiding a user who has not been trained in a professional to collect a sample on the sample collection portion 203.
In the embodiment shown in fig. 4, the container body is divided into two parts, i.e., a cylindrical portion 201A for forming a side wall of the accommodating hole, and a bottom plate 201B provided below the cylindrical portion 201A for forming a bottom wall of the accommodating hole. The sample collection portion 203 is provided on the bottom plate 201B. The cylindrical portion 201A and the bottom plate 201B are detachably joined together by, for example, snap-fitting to form a container body. After the collection of the sample is completed and the preservation container 200 is transported to a hospital or a testing center, the sample collection portion 203 can be easily accessed by detaching the cylindrical portion 201A and the bottom plate 201B. The sample collection portion 203 is detachable from the bottom plate 201B and is used for detection.
The sample collection unit 203 may be, for example, an FTA card, an FTA filter, filter paper, or the like.
According to the present invention, a sampling method for achieving self-sampling of cervical cells is as follows.
First, the user holds the sampler 100 and inserts it into the vagina of the person being sampled. In the case where the flap 140 is provided, the user may insert the sampler 100 into the vagina of the person to be sampled until the flap 140 comes into contact with the body of the person to be sampled.
The sampling head 122A is then extended by toggling the manipulation protrusion 124 to move within the manipulation aperture 110A. Sampling is performed by bringing the sampling head 122A to a corresponding depth (e.g., to the positioning hole 110B of each stage).
After sampling, the sampler 100 is taken out of the body of the person to be sampled and inserted into the receiving hole of the storage container 200. In the case where the above-described internal and external threads are provided, the sampler 100 may be conveniently inserted into the preservation container 200 by rotating it.
After the lower end surface 122A of the sampling head 122 contacts the sample collection portion 203, the sample may be smeared onto the sample collection portion 203 by, for example, pressing down, rotating, or the like. With the above-described internal and external threads provided, the sample can be smeared onto the sample collection portion 203 by continuing to rotate (e.g., 3-5 revolutions) the sampler 100 with the lower end face 122A of the sampling head 122 against the sample collection portion 203.
With the above-described sampling assembly (including sampler 100 and holding container 200 therein) and sampling method, a user can conveniently sample cervical cells of a person being sampled. Even if the education level of the user is not high or the manual ability is weak, the collection, collection and preservation of the sample can be effectively realized. Therefore, accurate and effective results of the cervical cell sample obtained by self-sampling can be effectively ensured during detection.
It is to be understood that "cervical cells" herein refers to "exfoliated cervical cells".
While the invention has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, the technical features mentioned in the embodiments can be combined in any way as long as there is no structural conflict. The present invention is not limited to the particular embodiments disclosed herein, but encompasses all technical solutions falling within the scope of the claims.
