Description

Technical Field

[0001] The present invention belongs to the technical field of cervical disease inspection and sampling, and in particular, relates to a cervical disease inspection and sampling device. Background Art

[0002] Cervical cancer often has no obvious symptoms in its early stages, so regular tests (such as cervical scraping or liquid-based cytology) can help women detect potential problems when they have no symptoms. Early detection means that intervention measures can be taken before the cancer develops to an advanced stage, greatly improving the cure rate. The examination can not only detect cancer, but also identify cervical intraepithelial neoplasia (CIN), which may develop into cervical cancer if not treated promptly. The sampling process is less invasive to the body, usually does not cause bleeding or pain, and the risk is relatively low. Cervical examinations are suitable for young women (such as after starting sexual life) to middle-aged women, helping to monitor the health of women of different ages. Regular examinations can significantly reduce the incidence and mortality of cervical cancer, especially in high-risk groups. The test results can help doctors develop a personalized treatment plan, including observation, regular examinations or further treatment.

[0003] Traditional cervical disease examination sampling devices are difficult to sample at a fixed point and are easily affected by secretions from other locations. At the same time, multiple operations will increase the patient's discomfort. Summary of the invention

[0012] Furthermore, there are multiple sampling ports, each of which is a square structure along the axial direction of the device.

[0013] Furthermore, the outer wall of the support component is configured as a wave-like structure, so as to increase the contact area between the support component and the patient's vagina to clean secretions.

[0014] Furthermore, the clamp is also provided with a lighting assembly, which includes LED lamp beads, a light guide column and a lens; the LED lamp beads are installed at the end position of the rotating rod to provide a lighting source; the light guide column is arranged inside the rotating rod to guide the light emitted by the LED lamp beads to the sampling head; the lens is installed at the front end of the sampling head to converge the light to the sampling area to improve visibility during sampling.

[0015] Furthermore, the secretion collecting layer is fixed to the outer wall of the sampling head and the outer wall of the supporting component through an adhesive layer, and the secretion collecting layer completely covers and wraps the outer wall of the sampling head and the supporting component.

[0016] Furthermore, the secretion collection layer comprises a surface layer, an absorption layer, a core layer and a bottom layer, wherein the surface layer, the absorption layer, the core layer and the bottom layer are fixed into an integral structure by sewing, and the adhesive layer is fixed on a side of the bottom layer away from the core layer;

[0020] Furthermore, the front end of the support assembly is an arc-shaped structure, and the sampling ports on the side walls thereof are all arranged along the front end direction of the support assembly;

[0021] The length of the sampling port is 1 / 10 of the length of the support assembly.

[0022] The beneficial effect of adopting the above-mentioned improvement scheme is that the support component is cylindrical in shape, and the cross-sectional diameter gradually decreases from one end to the other end. This design enables the device to smoothly penetrate into the patient's cervix.

[0023] Deep sampling: Through the gradually narrowing structure, the support component can effectively guide the sampling component deep into the cervix, facilitating accurate secretion sampling.

[0024] Material selection: The use of flexible rubber material can reduce pain when entering the patient's vagina and cervix and increase the patient's comfort.

[0025] Secretion collection layer: The secretion collection layer set on the outer wall can clean the secretions in the vagina to prevent them from interfering with the sampling process.

This design allows the sampling device to smoothly penetrate the patient's cervix to ensure that the target position can be reached during the sampling process. It is made of flexible rubber material to reduce the pain of the sampling device entering the patient's vagina and cervix and provide better comfort. A sampling port is provided on the side of the support component with a small cross-section, and the side of the sampling component close to this end is connected to the sampling port. This enables the sampling component to effectively extract secretions from the patient's cervix. The outer wall of the support component is equipped with a secretion collection layer to clean the secretions in the patient's vagina to prevent the sampling of the sampling component from being affected. The outer wall of the support component can be designed as a wavy structure to increase the contact area with the patient's vagina, thereby more effectively cleaning the secretions.

[0033] The sampling assembly includes a sampling head, a clamp and a lighting assembly. The sampling head is conical in shape and made of medical-grade silicone. The surface is covered with evenly distributed bristles, which helps to better collect cervical secretions. Fixed inside the sampling head, the clamp includes a rotating assembly and a connecting assembly. The rotating assembly is used to drive the connecting assembly to rotate, thereby assisting in sampling. The rotating assembly structure consists of two rotating rods and a rotating shaft. The rotating shaft is located in the middle of the two rotating rods. A safety spring is fixed in the middle to limit the rotation angle of the rotating rod to ensure the safety of the operation.

[0034] The secretion collection layer is composed of a surface layer, an absorption layer, a core layer and a bottom layer, which are fixed into an integrated structure by stitching. The surface layer is usually made of non-woven fabric, the absorption layer is a mixture of super absorbent polymer and fluff pulp, the core is polyurethane, and the bottom layer is a waterproof and breathable membrane. The surface layer is used to absorb vaginal secretions that come into contact; the absorption layer quickly locks the secretions; the core provides support for the whole and further locks the secretions; the bottom layer prevents the secretions from contacting the outer wall of the support component and the sampling head. The thickness of the secretion collection layer on the outer wall of the support component is 0.2-0.5cm, while the thickness of the collection layer on the outer wall of the sampling head is 0.5-0.8cm. This layer is tightly fixed to the outer wall of the support component and the sampling head by the adhesive layer to ensure that it will not fall off during use.

[0035] The number of sampling ports can be set to multiple, and the shape is a square structure along the axial direction of the device, and the length is 1 / 10 of the length of the support component.
