Description

Technical Field

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

[0002] In the field of obstetrics and gynecology, the examination of female vaginal secretions is extremely important. Vaginal secretions are a mixture of vaginal mucosal exudates, cervical canal and endometrial pancreatic secretions. It is not only an important indicator of the health of the female reproductive system, but also an important basis for diagnosing a variety of gynecological diseases.

[0003] Traditional methods of collecting vaginal secretions mostly use disposable sterile cotton swabs that are inserted directly into the vagina to adhere to the secretions, and then the cotton swab is placed in a test tube and sent to the laboratory for testing. However, this sampling method has many limitations and potential problems in actual operation. First, the cotton swab can easily come into contact with the inner wall of the vagina and the vulva during the insertion and removal process, causing the collected sample to be contaminated. This contamination may come from secretions from the inner wall of the vagina or microorganisms of the vulva, which in turn interferes with subsequent test results and affects the accuracy of the test. Secondly, because the sampling process is relatively cumbersome and requires professional medical personnel to operate,

[0004] For patients, it may cause certain discomfort and even psychological pressure.

[0005] In addition, the traditional sampling method also has problems with sample storage and transportation. If the sample is not stored properly or the transportation time is too long, the bioactive substances in the sample may degrade, further affecting the accuracy of the test results.

[0006] Therefore, a vaginal secretion sampling device is needed to solve the above technical problems. Summary of the invention

[0029] Example 2

[0030] In this embodiment, the arc plate 151 at the front end of the outer tube 1 can be controlled to open through the expansion component 15, so that the originally closed outer tube 1 is opened, which facilitates the extension of the internal sampling component 2; specifically, the expansion component 15 includes: an arc plate 151, a connecting line 153, a fixed block 154, a moving block 155 and a spring 156; the arc plate 151 is slidably installed on the wire groove 111 opened on the front end wall of the outer tube 1, and the wire groove 111 is installed with a connecting line 153, one end of the connecting line 153 is fixedly connected to the arc plate 151, and the other end of the connecting line 153 is fixedly connected to the moving block 155 slidably installed on the inner wall of the outer tube 1, and the side of the moving block 155 is installed with a spring 156, and the spring A fixed block 154 is installed at the end of 156, and the fixed block 154 is fixedly installed on the inner wall of the outer tube 1; when the trigger block 232 on the sampling component 2 contacts the moving block 155, the moving block 155 will be driven to move forward. During the movement, the spring 156 on the moving block 155 is compressed, and the connecting line 153 on the moving block 155 moves with it, pulling the arc block. At the same time, the spring 156 connected to the arc block is also compressed, and the arc block is stored, that is, the front end of the outer tube 1 is opened; an elastic block 152 is fixedly set at the end of the arc plate 151, and the elastic block 152 can form a seal between the contact surfaces of the arc plates 151 on both sides to prevent vaginal fluid from entering the outer tube 1 during the insertion process.

[0031] At the same time, in this embodiment, a circular groove is opened on the fixed cylinder 242, and a sampling swab 3 is detachably installed on the circular groove. A small cotton swab for Gram bacteria inspection and a brush for cervical liquid-based cells and HPV detection can be inserted through the circular groove. At the same time, in order to fix sampling swabs 3 of different sizes, an elastic block 152 can be installed inside the edge grass, and the needs of sampling swabs 3 for different sampling can be met through the extrusion of the elastic block 152; in addition, a sensing strip 243 is fixedly set at one end of the fixed cylinder 242, and the set sensing strip 243 can be used as a probe to facilitate the doctor to know whether the vaginal wall is contacted. The sensing strip 243 is made of a shape-changeable material, and its principle is similar to that of a gooseneck tube with a variable position. It is a prior art and will not be explained in detail here.

[0032] Example 3

In addition, an indicator light 112 is fixedly provided on the outer wall of the upper end of the outer tube 1; a handle 14 is fixedly provided on the outer wall symmetrical to the indicator light 112, and a battery 141 is installed inside the handle 14; combined with the induction strip 243 in Example 2, the induction strip 243 contacts the patient's vaginal wall, so that the circuit provided on the outer tube 1 can form a closed loop, further The indicator light 112 can be turned on. With such a setting, the doctor can easily know whether the sampling is successful. At the same time, in this embodiment, since the sampling component 2 is slidably arranged on the inner wall of the outer tube 1, in order to facilitate the removal and disinfection of the sampling component 2 without affecting the conductive circuit loop, a conductive coating is provided on the slide 101 and the slider 231. The conductive coating is used to conduct electricity, which can effectively solve the above problems.

[0034] The use principle of the present invention is as follows: after the preparation work is completed, lubricating liquid can be applied to the outer tube 1 first, and then the outer tube 1 can be slowly inserted into the patient's vagina. After insertion, the front and rear rods 21 can be pushed forward, and then the reversing rod 22 can be pulled, and the reversing rod 22 can be pulled slowly until the indicator light 112 lights up. At this time, the entire device can be slowly rotated for sampling. After completion, the reversing rod 22 is reset and the front and rear rods 21 are moved to the original position at the rear end. The device is then taken out, and the built-in sampling component 2 is taken out after taking it out. After that, the sampling of the sampling swab 3 inside is completed, and then the outer shell can be cleaned and disinfected, and a new sampling swab 3 or brush can be replaced to start the next use.
