Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, and more specifically, to a cervical cancer sample sampling device. Background Art

[0002] In order to detect cervical cancer and precancerous lesions in advance, patients need to use a cervical cancer sample sampling device for regular sampling examinations to ensure their own health.

[0003] For example, a cervical cancer screening sample sampler applied with the patent number 202120970773.8 includes a sampler housing and a sliding rod; Sampler housing: An annular plate is provided at the center of its interior, a limiting annular plate is provided at the opening at the bottom end of the interior of the sampler housing, and an annular card slot is provided at the lower end of the outer arc surface of the sampler housing; Sliding rod: It is slidably connected to the sliding hole at the center of the annular plate. A pressing block is provided at the top end of the sliding rod. Symmetrically arranged limiting sliding blocks are provided at the bottom end of the outer arc surface of the pressing block. A spring is provided between the bottom surface of the pressing block and the upper surface of the annular plate. The spring is sleeved outside the sliding rod. The bottom end of the sliding rod passes through the through hole in the middle of the limiting annular plate and a sampling insertion rod is installed at the end; This cervical cancer screening sample sampler can make cervical cells evenly adhere to the sampling brush head, quickly complete the sampling work, and can also protect the patient's body from being scratched during the sampling process, reducing the stinging sensation received by the patient.

[0004] Although this sampler can avoid scratching the patient during the sampling process, during the actual sampling process, the rotating sampler housing will rub against the inner wall of the vagina, which will affect the comfort of the patient. And when sampling, one hand needs to continuously press the pressing block, and the other hand needs to rotate the sampler housing to perform the sampling operation. Also, when removing the sampling brush head, one hand also needs to continuously press the pressing block to make the sampling brush head extend out of the sampler housing, resulting in an extremely cumbersome operation process.

[0031] Working principle of the utility model: when using the device, hold the sampler housing 1, and use the rubber strip 19 to increase the friction between the palm and the sampler housing 1, increase the stability of holding the sampler housing 1, then pull the sealing cover 15 to remove it from the sampler housing 1, so that the head of the sampler housing 1 is exposed, and then the head of the sampler housing 1 is inserted into the patient's vaginal opening, and then press the pressing head 5, the pressing head 5 is pressed down to drive the insertion rod 2 to move downward through the vertical rod 10, so that the insertion rod 2 drives multiple sampling brush heads 3 to extend from the sampler housing 1 and insert into the cervical opening, so that the side walls of the multiple sampling brush heads 3 contact the inner wall of the cervical opening, at this time, the pressing head 5 is pressed down to extend into the driving compartment 8, and then the positioning rod 21 uses the elastic force of the second spring 22 to make one end of it extend from the storage groove 20 and extend to the pressing head 5 , so as to limit the position of the pressing head 5 and prevent it from rebounding. Then, the rotating cylinder 7 can be rotated to drive the multiple sampling brush heads 3 to rotate, so that the multiple sampling brush heads 3 are scratched against the inner wall of the cervical opening, so that the cervical cells are attached to the sampling brush heads 3. Then, the driving rod 24 is toggled to drive the positioning rod 21 to be stored in the storage groove 20. At this time, the pressing head 5 returns to the starting position through the rebound of the No. 1 spring 9, and drives the multiple sampling brush heads 3 to be retracted into the sampler housing 1, and then the sampler housing 1 is pulled out of the vaginal opening, and then the insertion rod 2 and the sampling brush head 3 are removed from the vertical rod 10 and placed in the storage dish to complete the sampling operation. The annular rubber plug 16 is plugged into the annular sealing groove 17 to facilitate the sealing cover 15 to seal and protect the sampling brush head 3 to prevent it from being contaminated.
