A receiving member 124 provided on the mounting surface 123a in a telescopic connection;

the first sampling portion 121 and the second sampling portion 122 are both provided on the mounting surface 123a.

Referring to fig. 1-4, in this embodiment, during use, medical personnel insert sampling head 120 of disposable sterile cervical sampler 100 into the cervical orifice of a woman. The sampling handle 110 is fixed by the fixing plate 123, ensuring the stability of the sampler. Along with the extraction process of the sampler, the accommodating member 124 starts to be connected in a telescopic manner, so as to form an accommodating space 124a, and simultaneously, the first sampling part 121 and the second sampling part 122 are wrapped. The design ensures that the sampling part is not interfered by the inner wall of the cervix in the process of extraction, and reduces the falling of the sample.

The fixing plate 123 is a plate similar to an ellipse. The fixing plate 123 has a fixing surface 123b and a mounting surface 123a, and one end of the sampling handle 110 is fixedly connected to the fixing surface 123 b. The fixing plate 123 serves to fix the sampling handle 110, maintaining stability and reliability.

The receiving member 124 is mounted on the mounting surface 123a and is telescopically coupled thereto. The function of the cervical sampler is to form an accommodating space 124a in the sampling process, and wrap the first sampling part 121 and the second sampling part 122 at the same time, so as to prevent the cervical inner wall from generating pressure on the sampling part, and reduce sample falling.

The first sampling portion 121 and the second sampling portion 122 are both disposed on the mounting surface 123a, so that the first sampling portion 121 and the second sampling portion 122 are ensured to be located on the same plane, and are wrapped under the action of the accommodating member 124, so as to prevent interference from the cervical inner wall in the sampling process.

In at least one embodiment of the present application, the receptacle 124 includes:

a telescopic part 1241 having one end provided on the mounting surface 123 a;

an annular portion 1242 provided at an end of the extension portion 1241 remote from the mounting surface 123 a;

The telescopic portion 1241 may form an accommodating space 124a for accommodating the first sampling portion 121 and the second sampling portion 122.

In at least one embodiment of the present application, the diameter of the expansion part 1241 is denoted as c, and the diameter of the second sampling part 122 is denoted as d, satisfying the relationship: c > d.

In at least one embodiment of the present application, the diameter of the fixing plate 123 is denoted as e, and the minimum diameter of the annular portion 1242 is denoted as f, satisfying the relationship: d < f < e.

In the present embodiment, the diameter of the extension part 1241 is denoted as c, the diameter of the second sampling part 122 is denoted as d, and the relation c > d is satisfied. The diameter of the telescoping portion 1241 is greater than the diameter of the second sampling portion 122, ensuring that the telescoping portion 1241 can accommodate and wrap the second sampling portion 122, avoiding sample loss during sampling (withdrawal of the disposable sterile cervical sampler 100).

The diameter of the fixing plate 123 is denoted as e, and the minimum diameter of the annular portion 1242 is denoted as f, satisfying the relation d < f < e. The diameter of the annular portion 1242 is ensured to be larger than that of the second sampling portion 122, while being smaller than that of the fixing plate 123. It is ensured that the annular portion 1242 can cover and protect the second sampling portion 122, prevent the sample from falling off during sampling, and not interfere with the action of the fixing plate 123.

Referring to fig. 1 to 4, during sampling, the telescopic portion 1241 may be extended or contracted to form a suitable accommodating space 124a according to the specific situation and requirement of the cervix, so as to ensure that the first sampling portion 121 and the second sampling portion 122 can be completely accommodated and protected. The ring part 1242 surrounds the outer side of the telescopic part 1241 to further fix and protect the accommodated sampling part, so as to prevent the sample from falling off or being disturbed by the outside during the sampling process.

When disposable sterile cervical sampler 100 is extended into the cervix, the movement causes ring 1242 and telescoping 1241 to abut against fixed plate 123. This abutment ensures the stability of the sampler against accidental displacement during cervical access. At this time, the extension part 1241 forms an accommodating space 124a, and accommodates the first sampling part 121 and the second sampling part 122 therein.

After sampling, the ring 1242 is brought into contact with the inside of the cervix, and the cervix applies a certain force to the ring 1242 to fix it initially in the cervix. Then, as the disposable sterile cervical sampler 100 is pulled out, the extension/retraction portion 1241 forms an accommodation space 124a with the movement, and the first sampling portion 121 and the second sampling portion 122 are completely accommodated therein. At the same time, since the ring 1242 is in contact with the cervix, it is pulled out along with the withdrawal of the sampler. Thereby avoiding that the disposable sterile cervical sampler 100 can generate a certain extrusion force to the sampling head 120 due to the inner wall of the vagina in the process of drawing out, and the extrusion force can lead to the sample separation of a part of the sampling head 120 in the process of sampling. Thereby increasing the number of single-use sterile cervical sampler 100 samples.

The extension part 1241 is located on the mounting surface 123a, and has one end connected to the mounting surface 123a and the other end remote from the mounting surface 123a. The telescopic part 1241 has a telescopic property, and can form an accommodating space 124a for accommodating the first sampling part 121 and the second sampling part 122 during sampling; the extension 1241 may be made of a flexible material, such as, but not limited to, PET film, PE film, etc.

The annular portion 1242 is made of a deformable material such as, but not limited to, a rubber material, a plastic material, or the like.

The annular portion 1242 is located at the other end of the extension portion 1241 away from the mounting surface 123a. It forms an annular structure around the outside of the telescoping portion 1241. The annular portion 1242 serves to further fix and protect the housed first sampling portion 121 and second sampling portion 122, ensuring that they do not come off or be disturbed by the outside during sampling.

Note that c and f are equal.

In at least one embodiment of the present application, the annular portion 1242 has a first arcuate surface 1242a and a second arcuate surface 1242b;

the first arc surface 1242a and the second arc surface 1242b are both disposed at one side of the annular portion 1242 away from the first sampling portion 121;

the first arc surface 1242a is located at a side close to the sampling handle 110;

The second curved surface 1242b is located on a side away from the sampling handle 110.

In at least one embodiment of the present application, the second arc 1242b has a larger arc than the first arc 1242 a.

In at least one embodiment of the present application, the first sampling part 121 is provided with a first sampling end 1211, and the second sampling part 122 is provided with a second sampling end 1221;

the distance from the first sampling end 1211 to the fixed surface 123b is denoted as a, and the distance from the second sampling end 1221 to the fixed surface 123b is denoted as b.

In at least one embodiment of the present application, the maximum diameter of the annular portion 1242 is less than or equal to the maximum diameter of the fixing plate 123.

In this embodiment, the presence of the first arc surface 1242a and the second arc surface 1242b makes the annular portion 1242 fit more closely on the internal contact surface of the cervix, which is helpful to increase the contact area with the cervix and improve the stability of the sampler and the cervix.

The first curved surface 1242a is located on a side near the sampling handle 110, and can better contact and fix with the cervical outer opening, preventing the sampler from being accidentally separated or displaced during the movement process.

The second arc surface 1242b is located at a side far away from the sampling handle 110, and can better contact and fix with the inner side of the cervix, so as to ensure the stability of the sampler during the pulling-out process.

During extension, the first arcuate surface 1242a of the annular portion 1242 contacts the cervical outer opening to provide additional support against inadvertent displacement of the sampler during extension.

In the pulling-out process, the second arc surface 1242b of the annular portion 1242 is in contact with the inner side of the cervix, and the second arc surface 1242b can be better fixed in the cervix due to the large arc of the second arc surface 1242b, so that the stability of the sampler is maintained, and the falling-off of a sample is avoided.

It should be noted that, the ring portion 1242 is an integral part of the disposable sterile cervical sampler 100, and has two cambered surfaces, i.e., a first cambered surface 1242a and a second cambered surface 1242b.1242b

The first arc surface 1242a and the second arc surface 1242b are located at a side of the annular portion 1242, away from the position of the first sampling portion 121.

The first arc surface 1242a is located at a position of the annular portion 1242 near the side of the sampling handle 110.

The second curved surface 1242b is located at a position of the annular portion 1242 away from the sampling handle 110 side.

The radius of curvature of the second arc surface 1242b is larger than that of the first arc surface 1242a, i.e., the arc of the second arc surface 1242b is larger.

In at least one embodiment of the present application, the second sampling portion 122 is disposed around the first sampling portion 121 as a center.

Referring to fig. 1 to 4, in the present embodiment, the second sampling portion 122 is disposed around the first sampling portion 121, and is disposed around the first sampling portion 121 as a center of a circle.

By disposing the second sampling portion 122 around the first sampling portion 121, the sampling range and the coverage area of the sampler can be enlarged, and the collection efficiency and the comprehensiveness of the cervical sample can be improved.

The surrounding arrangement can ensure that the cell sample around the cervix is not missed or missed in the cervical examination process, so that the sampling is more comprehensive and accurate. So that the cell samples of the cervical orifice and the cervical canal can be collected at the same time, thereby improving the comprehensiveness and representativeness of the sampling.

Thereby, a single-use sterile cervical sampler 100 is provided, the single-use sterile cervical sampler 100 comprising:
