Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to a vaginal dilator that assists in collecting posterior fornix secretions. Background Art

[0002] Reproductive tract infection is a common and frequently occurring disease among women. It is a general term for a large class of diseases that cause female reproductive tract infection caused by the invasion of various bacteria, viruses, Candida, Trichomonas, Chlamydia, Mycoplasma and other pathogens. It usually includes various vaginitis, gonorrhea, cervicitis, Pasteurella cysts, pelvic inflammatory disease, etc., and has the characteristics of high incidence, high recurrence rate and wide prevalence. Infection is the source of many diseases. If reproductive tract infection is not diagnosed and treated in time, it can increase the risk of AIDS and cervical cancer, and cause complications such as infertility, ectopic pregnancy, miscarriage, stillbirth, premature birth, congenital infection and neonatal infection, chronic abdominal pain, etc., affecting the health of two generations. The premise of the treatment of female reproductive tract infection is accurate diagnosis, and the premise of accurate etiological diagnosis is the accuracy of the sample. At present, the method of collecting posterior fornix secretion specimens is as follows:

[0003] The first method is to use a disposable sterile cotton swab to directly insert into the posterior fornix to adhere to the secretions, and then put the cotton swab into a test tube for testing. This sampling method is prone to contamination of the collected samples by vaginal secretions and vulvar microorganisms during the insertion and removal of the cotton swab, thus affecting the accuracy of the test.

[0004] The second method: After the nurse or clinician opens the vagina with a vaginal dilator, a disposable sterile cotton swab is inserted into the posterior fornix to collect secretions, and the secretion swab is removed after completion. The use of a vaginal dilator can prevent the cotton swab from being contaminated by vaginal wall secretions and vulvar microorganisms during the sampling process, ensuring the accuracy of the sample. However, the private parts of the subject are completely exposed to the clinician or nurse during the sampling process, and their privacy is difficult to be guaranteed, which makes them prone to psychological pressure. At the same time, the operation of the vaginal dilator used clinically is cumbersome, and the collection of posterior fornix secretions requires the assistance of others, thereby limiting the self-sampling operation.

[0005] Therefore, in order to collect specimens that truly represent the microecology of the posterior fornix, it is an urgent problem for technical personnel in this field to develop a collector that can avoid contamination by vaginal wall secretions and vulvar microorganisms and can complete the sampling operation by itself. Summary of the invention

[0006] In view of this, the present invention provides a vaginal dilator for assisting in the collection of posterior fornix secretions, thereby improving the collection quality of posterior fornix secretion samples and reducing the deviation of subsequent testing and evaluation. The subject can operate the device by himself / herself without the assistance of others. A vaginal dilator is provided, which can avoid contamination by vaginal wall secretions and vulvar microorganisms and can self-complete the operation of collecting posterior fornix secretions.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] As attached Figure 1-3 As shown, a vaginal dilator for assisting in collecting posterior fornix secretions comprises: a hole ring 1, an inner tube 2 and an outer membrane 3;

[0028] A pull ring 11 is provided on the hole ring 1;

[0029] The body of the inner tube 2 passes through the hole ring 1 and is slidably matched with the hole ring 1, and the bottom end is connected with a hole buckle 4;

[0030] The outer membrane 3 is sleeved on the outer wall of the inner tube 2 , the top end of the outer membrane 3 is detachably connected to the hole ring 1 , and the bottom end is connected to the hole buckle 4 .

[0031] The principle of the above technical solution is: when in use, pull the pull ring 11 to press the top of the inner tube 2, so that the inner tube 2 extends along the hole of the hole ring 1. Under the stretching effect of the inner tube 2 and the fixing effect of the hole ring 1 and the hole buckle 4, the outer membrane 3 extends with the extension of the inner tube 2 to ensure that the outer membrane 3 is covered on the outer wall of the inner tube 2, that is, the outer membrane 3 and the inner tube 2 extend forward into the vagina together, and a disposable sterile cotton swab is extended into the posterior fornix through the holes of the hole ring 1, the inner tube 2, and the hole buckle 4 to collect secretions; after the sample is collected, the cotton swab is taken out along the original route, and then the vaginal dilator is taken out.

[0032] In some improved technical solutions, a pressing cap 5 with a hole is provided at the top of the inner tube 2, and the hole position of the pressing cap 5 with a hole corresponds to the tube mouth of the inner tube 2. The pressing cap 5 with a hole can reduce the force on the hand when pressing the inner tube 2 and improve the comfort of use.

[0033] In some improved technical solutions, elastic shrink rings 31 are provided at both ends of the outer membrane 3, a clamping ring 6 is fixed at the bottom end of the hole ring 1, and a clamping groove 61 is provided on the clamping ring 6, which matches the elastic shrinking ring 31. A limiting groove 41 is provided on the outer wall of the hole buckle 4, and the limiting groove 41 matches the elastic shrinking ring 31. The two ends of the outer membrane 3 are connected with the clamping ring 6 and the limiting groove 41 by an elastic shrinking ring 31, which not only facilitates assembly and disassembly, but also prevents the outer membrane 3 from falling off.

[0034] In some improved technical solutions, the inner wall of the hole buckle 4 is provided with an internal thread 42, the bottom end of the inner tube 2 is provided with an external thread 23 matching the internal thread 42, and the bottom end of the inner tube 2 is connected to the hole buckle 4 through thread matching.

[0035] In some improved technical solutions, the outer membrane 3 is made of flexible natural rubber or polyurethane, which reduces the friction between the device and the vagina when entering the vagina for sampling, while improving the softness of the device and avoiding damage to the vagina.

[0036] In some improved technical solutions, a limiting protrusion 21 and a limiting protrusion 22 are provided on the outer wall of the inner tube 2, and the tube body portion of the inner tube 2 located between the limiting protrusion 21 and the limiting protrusion 22 slides in the hole ring 1. The limiting protrusion 21 prevents the inner tube 2 from moving down too long during use and causing the upper end of the outer membrane 3 to fall off; the limiting protrusion 22 prevents the inner tube 2 from shrinking too much, squeezing the inner membrane 3, and affecting the use of the inner membrane 3.
