Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an iron cotton stick for urethral swab inspection. Background Art

[0002] A urethral swab is a medical test used to detect bacteria, viruses, or other microorganisms in the urinary tract. During a urethral swab, a doctor uses a long, thin cotton swab or a special swab to collect a sample from the patient's urethra. The sample is then sent to a laboratory for testing such as bacterial culture or polymerase chain reaction to determine if any pathogens are present.

[0003] In the existing urethral swab examination for men, due to the small urethral opening of men, the cotton swab used for sampling is often an iron cotton swab. The purpose is that the hardness provided by the iron swab when it is thin can effectively support the yarn cotton part at the end, and at the same time, the diameter of the yarn cotton part at the end is reduced, so as to facilitate better entry into the urethra. The cross-sectional diameter of the iron swab is usually between 1mm and 3mm, and the cross-sectional diameter of the yarn cotton part at the end is usually between 2mm and 4mm, and the length ranges from 1.5cm to 2.5cm.

[0004] When inserting the iron cotton swab into the patient's urethral opening, since the gauze cotton part needs to penetrate to a depth of 3cm to 4cm, even if the diameter of the gauze cotton cross-section is correspondingly reduced through the design of the iron cotton swab, the patient will experience strong discomfort during the process of inserting it into the patient's urethral opening. Research has found that the reason is that the urethra is very sensitive to external stimuli, and the gauze cotton will produce strong friction with the urethra during the process of inserting it into the urethra until it is inserted into the predetermined position. Therefore, the patient will experience strong discomfort throughout the whole process. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0023] Combination Figure 1-Figure 5 A urethral swab inspection iron cotton stick comprises a hand-held part 1, a iron cotton swab mechanism 3 is fixedly arranged at the lower end of the hand-held part 1, a test tube part 2 is arranged on the outer side of the iron cotton swab mechanism 3 to isolate it, the end of the iron cotton swab mechanism 3 is arranged as a hollow storage cavity 31, the storage cavity 31 is opened to the lower surface of the iron cotton swab mechanism 3, a rubber sleeve 4 is movably arranged in the storage cavity 31, the opening on the lower side of the rubber sleeve 4 is arranged on the outer surface of the lower end of the iron cotton swab mechanism 3, and a limiting convex ring 5 is arranged on the edge of the rubber sleeve 4, and a sampling cotton 7 is arranged on the inner wall of the rubber sleeve 4 near the top.

[0024] The utility model is further described below in conjunction with embodiments.

[0025] The above working principle and technical effect are as follows: the iron cotton swab mechanism 3 provides support hardness, and the rubber sleeve 4 is carried and inserted into the male urethral opening. Since the limiting convex ring 5 will be stuck at the entrance position of the urethral opening, the rubber sleeve 4 will gradually turn outward to the outer surface of the iron cotton swab mechanism 3 under the continuous advancement of the iron cotton swab mechanism 3. Initially, since the sampling cotton 7 responsible for sampling is stored on the inner side of the rubber sleeve 4, the contact between the sampling cotton 7 and the urethral opening is avoided in the initial stage when the iron cotton swab mechanism 3 pushes the rubber sleeve 4 into the urethral opening, and the friction between the sampling cotton 7 and the urethral opening is avoided, thereby reducing the patient's discomfort during the operation. In addition, in the process of the iron cotton swab mechanism 3 pushing the rubber sleeve 4 into the urethral opening, the rubber sleeve 4 is gradually turned outward. After the turned-out rubber sleeve 4 is attached to the inner wall of the urethral opening, the sliding degree is low under the limiting action of the limiting convex ring 5, thereby greatly reducing the friction with the urethral opening, further reducing the patient's discomfort during the operation.

[0026] When the iron cotton swab mechanism 3 pushes the rubber sleeve 4, the iron cotton swab mechanism 3 and the rubber sleeve 4 will only prop up the urethral opening, and the degree of friction with the inner wall is low. Since the inner wall tissue of the urethra itself has contraction elasticity and can adapt to being propped up, after reducing the degree of friction, it has a great improvement on the patient's discomfort during the operation.

[0027] In the previous embodiment, the inner wall of the rubber sleeve 4, except the area where the sampling cotton 7 is located, is coated with lubricant A8.

[0028] The above working principle and technical effect are: after the rubber sleeve 4 is everted, the lubricant A8 increases the lubrication degree between the rubber sleeve 4 and the inner wall of the urethra, so as to reduce the friction degree between the rubber sleeve 4 and the inner wall tissue of the urethra when the rubber sleeve 4 is pulled out;

[0029] The lubricant A8 is not applied to the area where the sampling cotton 7 is located, so as to avoid contamination of the sample sampled by the sampling cotton 7 .

[0030] In the previous embodiment, the lubricant B9 is filled between the inside of the storage cavity 31 and the outer surface of the rubber sleeve 4 .

[0031] The above working principle and technical effect are: by setting the lubricant B9, the sliding friction between the iron cotton swab mechanism 3 and the rubber sleeve 4 is reduced, so that the iron cotton swab mechanism 3 can better push the rubber sleeve 4 into the urethra.

[0032] In the previous embodiment: the length H1 of the sampling cotton 7 from the top downward inside the rubber sleeve 4 is set in the range of 1.5 cm to 2.5 cm, and the length H2 from the bottom of the sampling cotton 7 to the lower end of the iron cotton swab mechanism 3 is set in the range of 0.5 cm to 2.5 cm.

[0033] The above working principle and technical effect are: by setting appropriate lengths of H1 and H2, the sampling cotton 7 can be accurately delivered to the predetermined position in the urethra, which facilitates sampling and reduces the difficulty of operation for doctors.

[0034] In the previous embodiment: the cross-sectional diameter of the outer surface of the iron cotton swab mechanism 3 The range is set between 1mm and 2mm.

[0035] The above working principle and technical effect are: to prevent the rubber sleeve 4 from excessively stretching the urethra opening and causing excessive damage to the urethra after being sleeved on the outer surface of the iron cotton swab mechanism 3.

[0036] In the previous embodiment: the cross section between the lower surface, the outer wall and the inner wall of the iron cotton swab mechanism 3 is set to be an arc 32 .

[0037] The above working principle and technical effect are: the setting of the arc 32 facilitates the iron cotton swab mechanism 3 to smoothly push the rubber sleeve 4 to move deep into the urethra.

[0038] In the previous embodiment: an annular rubber pad 6 is arranged on the inner wall of the rubber sleeve 4 near the top, the lower side portion 61 of the annular rubber pad 6 is fixedly arranged integrally with the inside of the rubber sleeve 4, and a fastening ring of a fixed length is arranged on the upper side portion 62 of the annular rubber pad 6, the diameter of the fastening ring is consistent with the cross-sectional diameter of the iron cotton swab mechanism 3, and the sampling cotton 7 is arranged on the side of the annular rubber pad 6 away from the inner wall of the rubber sleeve 4.

[0039] The above working principle and technical effect are: when the rubber sleeve 4 is pushed to the outer surface of the iron cotton swab mechanism 3, the annular rubber pad 6 will also be spread flat on the outer surface of the rubber sleeve 4 to facilitate the sampling cotton 7 to extract the sample. After the extraction is completed, the iron cotton swab mechanism 3 is now pulled out. Without the support of the iron cotton swab mechanism 3, the rubber sleeve 4 will collapse to a certain extent. During the process of pulling back the rubber sleeve 4, the annular rubber pad 6 will be turned over by the resistance, and the side of the annular rubber pad 6 with the sampling cotton 7 will be turned to contact with the outer surface of the rubber sleeve 4, so as to cover the sampling cotton 7, thereby preventing the lubricant A8 remaining near the entrance of the urethra from contaminating the extracted sample during the process of pulling back the rubber sleeve 4.
