Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of auxiliary medical equipment, in particular to a sampling and testing device. Background Art
[0002] In the hospital, the diagnosis of diseases requires sampling and testing. When women suffer from gynecological diseases such as vulvitis, vaginitis or cervicitis, they need to go to the obstetrics and gynecology department of a regular hospital and actively cooperate with the doctor to conduct routine leucorrhea testing and examination. Testing leucorrhea requires sampling of leucorrhea. For married women or women who have had sexual life, they need to use a speculum to observe the leucorrhea first, and then use a cotton swab to take a more typical leucorrhea for examination; for women who have no sexual history, secretions are generally taken from the vaginal opening or vulva for examination. After sampling with a cotton swab, the cotton swab needs to be sent to the outpatient laboratory for examination. In this process, a test device is needed for transportation and transfer.
[0003] The existing inspection device is a test tube. After the leucorrhea is sampled with a cotton swab, the sampled cotton swab is placed in the test tube, and then the test tube is sent for inspection. Since there are three ways to inspect leucorrhea, the wet mount method, the instrument method, and the smear staining method; the existing test tube is directly filled with saline, and only the wet mount method can be used for inspection, but it can only determine the presence of trichomonas, mold, and cleanliness; therefore, the best way is to place the sampled cotton swab in the test tube without putting anything in the test tube. After the cotton swab is transported to the laboratory, the laboratory personnel can conduct different inspections.
[0004] However, if the cotton swab is placed directly in the test tube, it is easy for the cotton swab to shake in the test tube during transportation, especially in the event of an accident such as a collision, which will cause the cotton swab to come into contact with the inner wall of the test tube. This will easily cause the leucorrhea on the cotton swab to adhere to the inner wall of the test tube, reducing the amount of leucorrhea on the cotton swab. When the test is performed in the laboratory, it will make it impossible to perform the test, and repeated sampling will be required, which will increase the workload and cause the patient to feel uncomfortable. In addition, the reduced amount of sampling will also affect the test accuracy and results. Utility Model Content
[0005] In view of the above deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a sampling and testing device to reduce the adhesion of leucorrhea on the cotton swab to the inner wall of the test tube during the testing process.
[0006] The sampling and testing device includes a vertically arranged test tube, in which a fixed plate independent of the test tube and in a circular structure is arranged. A first through hole communicating with the upper and lower parts is opened in the middle of the fixed plate, and a slider is independently arranged in the first through hole. An adjustment mechanism for allowing the slider to slide horizontally is arranged on the fixed plate.
[0007] Furthermore, the adjustment mechanism includes a spring, and a mounting groove for the slider to slide horizontally back and forth is opened on the top of the fixed plate corresponding to the first through hole, and the spring is fixed between the rear side wall of the slider and the rear side wall of the mounting groove.
[0008] Furthermore, a through slot is provided on the fixing plate to connect the first through hole with the outside, and a fixing rod is vertically fixed on the top of the sliding block.
[0009] Furthermore, a limiting block is fixed on the top of the through slot, and the limiting block is used to prevent the sliding block from escaping from the installation slot.

[0019] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings, but this does not limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
[0020] The sampling and inspection device described in this embodiment is as follows: Figure 1 、 Figure 2 and Figure 3 As shown, it includes a vertically arranged test tube 1, the bottom of the test tube 1 is flat, and the test tube 1 can be placed directly on the table without tipping over, making it easy to take the test tube 1 for use. The test tube 1 is made of plastic and is a disposable item. Of course, the test tube 1 can also be made of glass and can be reused.
[0021] A fixed plate 2 is provided inside the test tube 1, which is independent of the fixed plate 2 and has a circular structure. A first through hole 2.1 is provided in the middle of the fixed plate 2, which is connected from top to bottom. That is, the first through hole 2.1 is located in the circular shape of the fixed plate 2. In this way, when the cotton swab is fixed in the first through hole 2.1, the cotton swab can be located in the middle of the test tube 1. A slider 7 is independently provided in the first through hole 2.1.
[0022] Corresponding to the first through hole 2.1, a mounting groove 2.2 for the slider 7 to slide horizontally back and forth is opened at the top of the fixed plate 2. A spring 8 is fixed between the rear side wall of the slider 7 and the rear side wall of the mounting groove 2.2. The front end of the spring 8 is fixed to the rear side wall of the slider 7, and the rear end of the spring 8 is fixed to the rear side wall of the mounting groove 2.2. The spring 8 allows the slider 7 to have space to move horizontally back and forth. When the spring 8 is in a natural state, the front side wall of the slider 7 contacts the front side wall of the first through hole 2.1, so that when the cotton swab stick is located between the slider 7 and the first through hole 2.1, the spring 8 can enable the slider 7 to fix the cotton swab stick in the first through hole 2.1. Preferably, the width of the first through hole 2.1 is smaller than the width of the slider 7, so that the slider 7 can better clamp the cotton swab stick and fix it in the first through hole 2.1; this paragraph of text as a whole constitutes an adjustment mechanism that enables the slider 7 to slide horizontally.
[0023] Of course, in actual use, the adjustment mechanism can also be a bolt. A first groove that is connected from top to bottom is opened on the fixing plate 2 on the rear side of the installation groove 2.2. A threaded hole that is threadedly matched with the screw rod of the bolt is opened on the fixing plate 2 between the first groove and the installation groove 2.2. The screw rod of the bolt passes through the threaded hole and is pressed against the rear side of the slider 7. The nut of the bolt is located in the first groove, and the nut of the bolt exceeds the top of the fixing plate 2, so that the screw rod of the bolt is rotated by the nut.
[0024] The fixing plate 2 is provided with a through slot 2.3 which connects the first through hole 2.1 with the outside. The front end of the first through hole 2.1 exceeds the through slot 2.3, so that the through slot 2.3 and the first through hole 2.1 form a horizontal "L"-shaped structure as a whole. When in use, after the top end of the cotton swab is held in hand and the leucorrhea is sampled by the cotton swab, the cotton swab can be directly placed from the through slot 2.3 into the first through hole 2.1, without the need to pass the cotton swab through the top of the first through hole 2.1, which is more convenient to operate. A fixing rod 6 is vertically fixed to the top of the slider 7, which facilitates the sliding block 7 to be pulled backward by the fixing rod 6 to compress the spring 8 so that the cotton swab enters the first through hole 2.1 from the through slot 2.3.
[0025] The limit block 5 is fixed on the top of the through slot 2.3, and the limit block 5 is used to prevent the slider 7 from disengaging from the mounting slot 2.2. The limit block 5 is fixed on the top of the mounting slot 2.2, and the top surface of the limit block 5 is flush with the top surface of the fixed plate 2. A gap is left between the limit block 5 and the bottom of the mounting slot 2.2 for horizontal sliding of the slider 7. The slider 7 slides horizontally between the limit block 5 and the bottom of the mounting slot 2.2. Of course, a first through slot is provided on the limit block 5 located above the through slot 2.3 and the first through hole 2.1, so that the limit block 5 will not block the cotton swab rod from entering the first through hole 2.1 from the through slot 2.3. The limit block 5 can, on the one hand, prevent the slider 7 from disengaging from the mounting slot 2.2 when the spring 8 is compressed, and on the other hand, it can limit the forward and backward sliding of the slider 7 to prevent the slider 7 from tilting, so that the slider 7 can better clamp the cotton swab rod and fix it in the first through hole 2.1.
[0026] The side wall of the fixing plate 2 is provided with a rubber ring 3, which is made of rubber and is in the shape of a ring. The rubber ring 3 is fixedly sleeved on the fixing plate 2. The rubber ring 3 can prevent the fixing plate 2 from contacting the diameter of the inner wall of the test tube 1, thereby protecting the test tube 1. In addition, the rubber ring 3 has a certain elasticity, which can make the fixing plate 2 and the inner wall of the test tube 1 fit more closely. Of course, a second through groove is opened on the rubber ring 3 corresponding to the through groove 2.3, so that the cotton swab can enter the through groove 2.3 from the second through groove.
[0027] The mouth of the test tube 1 is provided with a test tube cover 4 for sealing it. The test tube cover 4 is threadedly matched with the test tube 1. Of course, the test tube cover 4 can also be interference-fitted with the test tube 1. The mouth of the test tube 1 can be sealed by the test tube cover 4, thereby effectively reducing the outside gas from entering the test tube 1 through the through groove 2.3, reducing the contact between the leucorrhea on the cotton swab and the outside air, and reducing the contamination of the sampled leucorrhea.
[0028] The test tube cover 4 is provided with a second through hole communicating with each other from top to bottom, and the second through hole is used for a cotton swab to pass through. When in use, after the fixing plate 2 and the cotton swab are inserted into the test tube 1, the test tube cover 4 is covered on the test tube 1, so that the top end of the cotton swab passes through the second through hole on the test tube cover 4 and is located above the test tube cover 4, and the cotton swab will block the second through hole. In this way, after the test tube 1 is transported into the laboratory, it is convenient for the laboratory technician to hold the top end of the cotton swab to remove the fixing plate 2 and the cotton swab from the test tube 1.
[0029] Working principle:
[0030] During use, the leucorrhea is sampled with a cotton swab. After the sampling is completed, the fixing plate 2 is taken out of the test tube 1, and the slider 7 is pulled backward by the fixing rod 6 to compress the spring 8. Then the cotton swab is placed from the through groove 2.3 to the first through hole 2.1. The fixing rod 6 is loosened to restore the elasticity of the spring 8, so that the slider 7 clamps the cotton swab in the first through hole 2.1. Then the fixing plate 2 is placed in the test tube 1 so that the cotton swab is located in the test tube 1. Because the fixing plate 2 fixes the cotton swab, the contact between the cotton swab and the inner wall of the test tube 1 can be reduced when the test tube 1 is transported, thereby reducing the leucorrhea on the cotton swab from adhering to the inner wall of the test tube 1, so that the sampling amount of leucorrhea on the cotton swab will not be reduced, reducing errors in the test results and avoiding repeated sampling.
