Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a vaginal secretion sampling and storage device. Background Art

[0002] During gynecological examinations, in order to facilitate the assessment of the vaginal environment and the diagnosis of diseases such as infection or inflammation, the patient's vaginal secretions are usually sampled and preserved, providing effective samples with biological activity for the accurate diagnosis, disease monitoring and scientific research analysis of gynecological diseases. In order to facilitate the sampling and preservation of vaginal secretions, medical staff usually use vaginal secretion sampling and preservation devices. Existing vaginal secretion sampling and preservation devices usually consist of test tubes, tube caps and cotton swabs.

[0003] For example: The utility model patent with application number CN202022681946.2 discloses a vaginal secretion sampling tube. Specifically, the utility model discloses a vaginal secretion sampling tube, comprising a test tube, a tube cap and a sampling cotton swab fixed on the tube cap at one end, the tube cap is detachably fixed at the first opening of the test tube, and the tube cap is provided with a accommodating cavity for accommodating liquid and a destruction component for destroying the accommodating cavity to allow the liquid to flow into the test tube, and also includes a seal detachably mounted at the second opening. According to the above structural description, when in use, the destruction component is triggered to release the liquid into the test tube and mix with the secretions on the sampling cotton swab, and then the seal is removed and the test tube is squeezed to drip out the suspension. Therefore, the impact of manual operation on the test results is reduced, and at the same time, the secretions are avoided from contaminating the environment and infecting the inspectors after the second opening, which is conducive to improving the accuracy and safety of the test.

[0004] However, existing vaginal secretion sampling and preservation devices usually use cotton swabs to sample vaginal secretions and then place them in test tubes for preservation. Although cotton swabs can effectively absorb vaginal secretions, the fiber structure of cotton swabs is loose, forming a large amount of surface contact with air. When the sample is separated from the moist environment of the human body, the moisture adsorbed by the cotton swab will slowly evaporate through the fiber gaps. Once the sampling time is too long, the sample is likely to dry out and affect the biological activity of the sample, resulting in the need for resampling. The operation is cumbersome and inconvenient to use. Summary of the Invention

[0005] In view of this, the present invention provides a vaginal secretion sampling and preservation device, which has a moisturizing block that can automatically moisturize the sample. After the sampling is completed, it is only necessary to turn the control knob to make the auxiliary groove deviate from the control slide bar. At this time, when the sampling tube cap is inserted into the sample storage test tube, the annular limit frame will squeeze the control slide bar, and then the seal of the storage bin will be released through a series of transmissions. At the same time, as the control slide bar moves, the fixed slide bar will be driven to move, and as the fixed slide bar moves, the control pressure plate will be driven to slide in the storage bin. As the control pressure plate moves, the moisturizing block will be squeezed. After the moisturizing block is squeezed, the cell preservation fluid will flow out and infiltrate the vaginal secretion sample.

[0043] Specific usage and function of this embodiment: In the present invention, in the process of sampling vaginal secretions, by pressing the pressing seat 125, the pressing seat 125 drives the control slide 124 to move and squeeze the return spring 126. As the control slide 124 moves, the control push plate 127 is driven to slide in the fixed card slot 128. As the control push plate 127 slides, the fixed card block 122 is squeezed to move and squeeze the auxiliary spring 123. As the fixed card block 122 moves, it is disengaged from the fixed card slot 128. At this time, the sampling tube cap 101 can be pulled out, and the vaginal secretions can be sampled through the cotton swab head 103. After the sampling is completed, it is only necessary to reinsert the sampling cotton swab 102 into the sample test tube 1 and make the sampling The sample tube cap 101 is reinserted into the sample test tube 1. At the same time, during the reinsertion process of the sample tube cap 101, the sample tube cap 101 will squeeze the fixed block 122, causing the fixed block 122 to slide in the sample test tube 1 and squeeze the auxiliary spring 123. After the sample tube cap 101 is completely inserted into the sample test tube 1, the fixed block 122 will rebound under the action of the elastic potential energy of the auxiliary spring 123, causing the fixed block 122 to be reinserted into the fixed slot 128 to fix the sample tube cap 101. After the sampling is completed, it is only necessary to turn the control knob 114 to drive the control rotating frame 116 to rotate. During the rotation of the control rotating frame 116, the limiting groove 119 will slowly engage with the limiting ball The position of 120 is aligned. After rotating forty-five degrees, the limiting groove 119 is just aligned with the position of the limiting card ball 120. At this time, the limiting card ball 120 will be inserted into the limiting groove 119 under the elastic potential energy of the fixing spring 121, and the position of the control rotating frame 116 is locked. In the initial state, the control knob 114 will always align the auxiliary groove 118 with the position of the control slide bar 104 under the elastic potential energy of the connecting torsion spring 115. At this time, the insertion of the sampling tube cap 101 will not squeeze the control slide bar 104, and after the control knob 114 is rotated, the auxiliary groove 118 will deviate from the control slide bar 104. At this time, when the sampling tube cap 101 is inserted into the sample test tube 1, the annular limiting frame 117 will The control slide 104 is squeezed to make it slide. During the sliding process of the control slide 104, the guide slide 105 is driven to move. As the guide slide 105 moves, the guide spring 106 is squeezed. The setting of the guide slide 105 can guide the control slide 104.

[0045] Specific usage and function of this embodiment: In the present invention, the moisturizing block 113 is an immersion sponge, which is soaked with cell preservation fluid. As the control slide 104 moves, the fixed slide 107 will be driven to move. As the fixed slide 107 moves, the control pressure plate 108 will be driven to slide in the storage bin 112. As the control pressure plate 108 moves, the moisturizing block 113 will be squeezed.
