Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, to a vaginal secretion sampling device for obstetrics. Background Art

[0002] As an important part of the detection process in obstetrics and gynecology, vaginal secretion detection can determine the hormone levels, inflammation conditions, microbial colony status, etc. in the vagina based on the secretions at different positions in the female vagina. For this purpose, a special sampling device is required clinically to sample the vaginal secretions.

[0003] Traditional sampling methods mostly use cotton swabs for sampling. On the one hand, it is not easy to insert the cotton swab deep into the vagina, and at the same time, it is prone to contamination during the process. For this, reference can be made to the prior patent with the application number CN202411644117.3, a vaginal secretion sampling device. The characteristics of this type of device are that the built-in sampling block is sent into the vagina through the outer shell to complete the sampling. Since the vagina itself is a curved and upper-wide and lower-narrow pipeline, when using this type of sampling device, on the one hand, its rigid structure will cause great discomfort to the vagina, and at the same time, its sampling position is relatively single, and it is necessary to repeatedly operate the instrument to complete multi-point sampling, resulting in very inconvenient operation. Therefore, it needs to be improved. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a vaginal secretion sampling device for obstetrics to solve the above technical problems.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: A vaginal secretion sampling device for obstetrics, comprising: A columnar elastic body, one end of the elastic body is blocked to form a driving end, and the other end forms a connecting end. A deformation cavity is formed in the elastic body along the length direction corresponding to the connecting end; A sleeve, a receiving cavity is formed in the sleeve, the connecting end is connected to one end of the sleeve, and the driving end is used to deform towards the deformation cavity and be received in the receiving cavity; A driving rod, one end of the driving rod is connected to the bottom of the deformation cavity, and the driving rod is used to push along the length direction of the sleeve to drive the driving end to deform away from the deformation cavity to form a columnar structure.

[0006] As a further improvement of the present invention, a guiding arc surface is formed by inward depression at the top of the connecting end.

[0007] As a further improvement of the present invention, adsorption strip bands are provided on the surface of the elastic body along the length direction.

[0008] As a further improvement of the present invention, the connecting end is provided with a covering edge, the covering edge extends away from the elastomer, and the covering edge sleevingly sets a sleeve.

[0009] As a further improvement of the present invention, a limiting block is arranged on the outer wall of the driving rod along the length direction, a limiting groove is arranged on the sleeve corresponding to the limiting block, and the limiting block slides with the limiting groove to limit the rotation of the driving rod relative to the sleeve. The adsorption strip corresponds to the limiting block. When the driving rod is located in the deformation cavity, the limiting block abuts against the area of the elastomer corresponding to the adsorption strip to keep the adsorption strip protruding relative to the elastomer.

[0010] As a further improvement of the present invention, the outer diameter of the driving rod is consistent with the aperture of the deformation cavity.

[0011] As a further improvement of the present invention, the driving rod is made of deformable material.

[0012] As a further improvement of the present invention, a protection surface is arranged at one end of the sleeve away from the elastomer, and the protection surface is used to abut against the human body to limit the maximum range of the sleeve entering the human body.

[0013] Advantages of the present invention: 1. By arranging a deformation cavity inside the elastomer and cooperating with the storage cavity, the elastomer can be pre-received into the storage cavity and attached to the vaginal inner wall in an unfolded manner, thus avoiding direct movement in the vagina and greatly improving the sampling comfort. 2. By changing the unfolded and stored states of the elastomer, the sampling operation for the entire vagina can be achieved through the outside of the elastomer only by operating once, thus greatly reducing the sampling operation time. 3. By means of the driving rod, the deformation of the elastomer can be facilitated while improving the stability of the deformation of the elastomer during storage, thereby reducing the risk of contamination in adjacent areas or misaligned deformation resulting in inability to be stored.

Detailed implementation

[0016] The present invention will be further described in detail below in conjunction with the drawings and embodiments. The same components are denoted by the same reference numerals.

[0017] Figures 1-4 This is the first embodiment of the present invention. A vaginal secretion sampling device for obstetrics includes: a columnar elastomer 1, which is preferably made of silica gel to improve human comfort. One end of the elastomer 1 is blocked to form a driving end 2, and the other end forms a connecting end 3. A deformation cavity 4 is provided in the elastomer 1 along the length direction corresponding to the connecting end 3, so that the elastomer 1 forms a thin wall to facilitate deformation into the deformation cavity 4.

[0018] It further includes a sleeve 5. A receiving cavity 6 is formed in the sleeve 5. The connecting end 3 is connected to one end of the sleeve 5, and the driving end 2 is used to deform towards the deformation cavity 4 and be received in the receiving cavity 6.

[0019] It further includes a driving rod 7. One end of the driving rod 7 is connected to the bottom of the deformation cavity 4. The driving rod 7 is used to push along the length direction of the sleeve 5 to drive the driving end 2 to deform away from the deformation cavity 4 to form a columnar structure.

[0020] In the initial state, the elastomer 1 is in a received state, that is, the elastomer 1 deforms into the deformation cavity 4, so that the columnar structure formed by the elastomer 1 is located in the receiving cavity 6. At this time, the bottom of the deformation cavity 4 is exposed, and the driving rod 7 is connected to the bottom of the deformation cavity 4.

[0021] In the use state, insert part of the sleeve 5 into the vaginal orifice. Further, by pushing the elastomer 1, the elastomer 1 in the receiving cavity 6 is driven to move forward relative to the sleeve 5. Thus, due to the elasticity of the elastomer 1 itself and the pushing of the driving rod 7, the elastomer 1 deforms away from the deformation cavity 4 to re-form a columnar structure facing the front of the sleeve 5. Further, medical staff can complete sampling at multiple positions on the vaginal wall by bringing the side wall of this columnar structure into contact with the vaginal wall. After sampling is completed, the driving rod 7 is retracted, thereby driving the elastomer 1 to deform back into the deformation cavity 4 again, so that the elastomer 1 is received back into the receiving cavity 6, and the sleeve 5 is withdrawn to complete the overall sampling operation.

[0022] Alternatively, when the driving rod 7 enters the vagina, a small amount of the elastomer 1 can be kept in the deformation cavity 4 to improve the stability during the reverse deformation.

[0023] Further, the elastomer 1, the sleeve 5, and the drive rod 7 are all for single use to avoid cross-infection.

[0024] Since the elastomer 1 deforms to enter the vagina, it can avoid the discomfort caused to the vagina by moving in the vagina to the greatest extent. At the same time, the sampling operation at multiple positions in the vagina can be completed with only one operation, making the overall sampling operation simple and fast. At the same time, the overall structure is simple and reliable, and the cost is low.

[0025] Preferably, a guiding arc surface 8 is formed by inward depression at the top of the connecting end 3.

[0026] Through the setting of the guiding arc surface 8, the force on the connecting end 3 can be improved when the drive rod 7 retracts, thereby accelerating the deformation speed of the connecting end 3 towards the deformation cavity 4 to improve the stability of the overall deformation of the elastomer 1.

[0027] Preferably, an adsorption strip 9 is provided on the surface of the elastomer 1 along the length direction.

[0028] Through the setting of the adsorption strip 9, the adsorption of secretions can be ensured to reduce the problem that the adjacent secretions are likely to move after retraction, resulting in a decrease in sampling accuracy.

[0029] Among them, after the sampling is completed, the adsorption strip 9 can be removed for detection, or the elastomer 1 or the whole device can be directly sent for inspection.

[0030] Preferably, the connecting end 3 is provided with a covering edge 10, the covering edge 10 extends away from the elastomer 1, and the covering edge 10 sleevs the sleeve 5.

[0031] Through the setting of the covering edge 10, the comfort when the sleeve 5 enters can be ensured.

[0032] Preferably, a limiting block 11 is provided on the outer wall of the drive rod 7 along the length direction, a limiting groove 12 is provided on the sleeve 5 corresponding to the limiting block 11, and the limiting block 11 slides with the limiting groove 12 to limit the relative rotation of the drive rod 7 with respect to the sleeve 5. The adsorption strip 9 corresponds to the limiting block 11. When the drive rod 7 is located in the deformation cavity 4, the limiting block 11 abuts against the area of the elastomer 1 corresponding to the adsorption strip 9 to keep the adsorption strip 9 protruding relative to the elastomer 1.

[0033] Specifically, the number of both the adsorption strip 9 and the limiting block 11 is 3, and they are arranged circumferentially, and the adjacent adsorption strips 9 or limiting blocks 11 form an included angle of 120 degrees.

[0034] By restricting the driving rod 7, it is possible to avoid the incorrect deformation of the elastic body 1 caused by the rotation of the driving rod 7 during the entry and retraction processes, thereby ensuring the controllability of the deformation of the elastic body 1 to the greatest extent. At the same time, by using the limiting block 11 to correspond to the adsorption strip 9, it is also possible to ensure the contact between the adsorption strip 9 and the vaginal wall, thereby ensuring the sampling effect of the adsorption strip 9.

[0035] Preferably, the outer diameter of the driving rod 7 is the same as the aperture diameter of the deformation cavity 4.

[0036] Thus, the controllability of the deformation direction of the elastic body 1 is ensured to the greatest extent.

[0037] Preferably, the driving rod 7 is made of a deformable material, and specifically preferably medical plastic.

[0038] By using the deformable material of the driving rod 7, it can undergo adaptive deformation after entering the vagina, thereby adapting to the shape of the vagina and greatly improving the comfort level.

[0039] Furthermore, in order to better fit the shape of the vagina, the aperture diameter of the elastic body 1 decreases from the connecting end 3 to the driving end 2, and at the same time, the driving rod 7 is adapted thereto.

[0040] Preferably, a protective surface 13 is provided at one end of the sleeve 5 away from the elastic body 1, and the protective surface 13 is used to contact the human body to limit the maximum range of the sleeve 5 entering the human body.

[0041] By providing the protective surface 13, it is possible to prevent the sleeve 5 from accidentally entering the vagina during operation, thereby improving the overall safety.

[0042] Figure 5 This is the second embodiment of the present invention. The difference from the first embodiment is that the number of adsorption strips 9 is multiple and arranged along the length direction of the elastic body 1, and the multiple adsorption strips 9 are mutually offset along the length direction of the elastic body 1.

[0043] In this embodiment, the preferential deformation position of the elastic body 1 is located at the connection between the elastic body 1 and the sleeve 5. Therefore, offsetting the adsorption strips 9 along the length direction of the elastic body 1 can ensure that the samples on the adsorption strips 9 are not contaminated with each other when the preferential deformation position of the elastic body 1 is located at the connection with the sleeve 5.

[0044] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
