Description

TECHNICAL FIELD

[0001] The utility model relates to a thermoplastic polyurethane film semen collection sleeve belongs to the medical instrument technical field. BACKGROUND

[0002] In the hospital's reproductive health male medical department, infertile diagnosis and treatment and human assisted reproduction, reproductive medical research and human sperm bank, the need to collect male semen completely and without pollution, for sperm quality detection and disease diagnosis and treatment, and human sperm freezing storage.

[0003] The World Health Organization stipulates that semen collection is best done by masturbation, and the semen is collected completely in a wide-mouth glass or plastic container that is non-toxic and sterile to sperm. In special cases, semen collection can be done in a specially designed condom that is non-toxic to sperm. Until now, hospitals all over the world use this method of collecting semen. Many patients report that this method of operation is difficult to master, and even feels painful, and is not hygienic. The wide-mouth glass or plastic container is cumbersome to hold, needs to be treated with non-toxic and sterile processing and packaging in advance, is very troublesome, and is not necessarily reliable, making it difficult to collect and measure the total amount of semen completely. If a natural latex rubber male condom is used to collect semen by masturbation, the inner wall of the commercially available male condom is attached with white carbon black powder and isolated lubricant silicone oil, which will contaminate the collected semen and interfere with the detection and evaluation of the semen. It is difficult for factories and distributors of male condoms to supply specially designed male condoms without white carbon black powder and isolated lubricating silicone oil to hospitals, and to carry out sterilization packaging. If commercially available male condoms are washed, dried, packaged and sterilized, it is still relatively troublesome, and the cost is also not low.

[0004] Utility model patent CN-201476987u (2010, 05, 19) a semen collector, using a triangular plastic funnel lower end connected with a scale plastic centrifuge tube, collecting the semen ejaculated by masturbation. This semen collector and the method of using and operating are not perfect enough in terms of operation convenience, hygiene and comfort. SUMMARY

[0005] The utility model aims at providing a thermoplastic polyurethane film semen collection sleeve of new material and new structure. The technical scheme adopted is that a clean two-layer thermoplastic polyurethane smooth film new material with high elasticity, softness and smooth feeling when contacting the skin is used, and is formed by plastic film electric heat sealing cutting welding method. A film sleeve body (1) and a semen storage sac (2) connected integrally are made. Then, a thermoplastic polyurethane elastomer sleeve opening ring (3) is bonded to the opening end of the film sleeve body (1) by electric heat sealing cutting welding method.

[0006] The advantages of the new material and structure of the human semen collection set are that the thin film set body and the semen storage bag are made of the clean two-layer thermoplastic polyurethane smooth film new material with high elasticity, softness and skin contact smooth feeling, the patient feels comfortable and is easy to be excited to ejaculate when collecting semen by the hand method. The thermoplastic polyurethane smooth film material is clean in surface without toxicity, sterility, lubricating silicon oil, white carbon black powder particles and is a medical film material without skin and mucous membrane irritation. Therefore, the human semen collection set is safe and effective for collecting and containing semen, does not pollute the collected semen and does not interfere with the next laboratory processing of the semen and detection and evaluation work. The adhesive set mouth ring is convenient, easy and sanitary for the patient to hold and stabilize the whole semen collection set and operate.

[0007] The new human semen collection set can be used for the special tools of the hospital reproductive health male medical department, sperm quality detection and evaluation, diagnosis and treatment of infertility, human assisted reproduction, reproductive medical research and human sperm bank semen collection.

[0010] The preferred embodiment of the utility model discloses a mold for thermoplastic plastic film electric heat sealing cutting and welding is made according to the drawing size of the thermoplastic polyurethane film semen collection set and is installed on the mold holder of the thermoplastic plastic film electric heat sealing cutting and welding machine. Two-layer clean thermoplastic polyurethane smooth film is electric heat sealing cutting and welding to make the thin film set body (1) and the semen storage bag (2) connected integrally of the semen collection set. The pre-injection-molded thermoplastic polyurethane elastomer ring is placed on the thermoplastic plastic electric heat sealing cutting and welding machine, and the opening of the thin film set body (1) is welded with the thermoplastic polyurethane elastomer ring to become the set mouth ring (3). The whole formed thermoplastic polyurethane film semen collection set is processed, arranged, inspected, packaged and sterilized to become a medical instrument for hospital patients.
