Description

Technical Field

[0001] This utility model relates to the technical field of sperm collection equipment, and in particular to a flexible multilayer structure that prevents corrosion. Background Technology

[0002] In clinical medicine, semen analysis is the most basic and essential test for assessing male fertility. To perform semen analysis, a semen sample must first be obtained from the male. Currently, most collection methods involve manual collection or manual stimulation, although some sperm collection devices can assist in the process.

[0003] For example, andrology is a medical specialty for men's health. Among the examinations for men, routine semen analysis is a special type of examination. This examination requires the use of the male patient's semen. With the development and progress of technology, most current technologies use semen collection devices to assist patients in the semen collection process. While using a semen collection device can assist patients in collecting semen, it can only provide a carrier and cannot significantly improve the speed of semen collection.

[0004] For example, Chinese patent document CN214965905U discloses a storage device for male semen testing, including a box, a semen collection tube fixedly installed on the inner top wall of the box, an external thread fixedly installed on the end of the semen collection tube away from the box, a semen collection bottle provided below the external thread, a bottleneck fixedly installed on the outer top wall of the semen collection bottle, an internal thread provided on the inner circumferential wall of the bottleneck, and the external thread matching the internal thread.

[0005] The storage device for male semen testing, with its pad, collection tube, and through-hole, allows for the collection of male semen. However, the pad alone cannot adequately assist patients in the collection process, and the collection speed may even decrease.

[0006] Traditional sperm collection equipment faces several problems in practical use, primarily including collection failures due to patient anxiety and insufficient stimulation intensity, making it difficult for some less sensitive patients to complete the collection process successfully. Studies have shown that the patient's psychological state during sperm collection has a significant impact on the results; tension and anxiety directly affect ejaculation ability, leading to frequent collection failures.

[0007] Meanwhile, existing equipment often lacks flexibility in design and cannot adapt to the individual needs and comfort levels of different patients. Because different patients have varying sensitivities to stimulation, the single stimulation method provided by traditional equipment cannot meet the needs of all patients, leading to a lower success rate in data acquisition.

[0008] In terms of materials, the inner sleeve and outer sleeve are usually made of different materials, and direct contact between the two may cause surface adhesion or swelling, which is similar to a corrosion effect and seriously affects the service life of the equipment. When flexible materials are used for a long time or in contact with high temperature environments, their molecular structure may change, leading to adhesion and further deteriorating the user experience and equipment performance.

[0009] Based on the above problems, designing a novel flexible multilayer structure has become an urgent technical issue to be addressed. Utility Model Content

[0010] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0011] This utility model provides a flexible multilayer structure to prevent corrosion, comprising a flexible inner sleeve and a flexible outer cylinder made of flexible materials. The flexible outer cylinder is sleeved on the outer surface of the flexible inner sleeve, so that when the flexible outer cylinder is deformed by external force, it causes the flexible inner sleeve to deform synchronously, changing the shape of the internal space of the flexible inner sleeve. An isolation layer is provided in the space between the flexible inner sleeve and the flexible outer cylinder. One side of the isolation layer abuts against the outer surface of the flexible inner sleeve, and the other side abuts against the inner surface of the flexible outer cylinder, thereby isolating the flexible inner sleeve and the flexible outer cylinder from each other.

[0012] Furthermore: the flexible inner sleeve is made of thermoplastic elastomer material, and the flexible outer sleeve is made of silicone material.

[0013] Furthermore, the isolation layer is made of polytetrafluoroethylene film material, thereby separating the flexible inner sleeve from the flexible outer sleeve.

[0014] Furthermore, the isolation layer is made of polyethylene film material, thereby separating the flexible inner sleeve from the flexible outer sleeve.

[0015] Furthermore, the insulating layer is configured as a silicone coating, thereby separating the flexible inner sleeve from the flexible outer sleeve.

[0016] Furthermore, the isolation layer is made of sponge material, thereby separating the flexible inner sleeve from the flexible outer sleeve.

[0017] Furthermore, the isolation layer is made of sponge with a certain thickness, which separates the flexible inner sleeve from the flexible outer sleeve.

[0018] Furthermore, the two ends of the flexible outer cylinder are detachably fixed to the two ends of the flexible inner sleeve.

[0019] Furthermore, the two ends of the flexible outer cylinder are respectively glued to the two ends of the flexible inner sleeve using an adhesive process.

[0020] Furthermore, end caps are provided at both ends of the flexible outer cylinder.

[0021] Compared with the prior art, the beneficial effects of this utility model are: 1. Assisted Sperm Collection: The flexible, multi-layered structure allows patients to squeeze the material according to their own needs, effectively relieving their anxiety and assisting in the sperm collection process. Simultaneously, the squeezing causes deformation of the flexible inner sheath, enhancing stimulation and helping less sensitive patients complete the collection process smoothly.

[0022] 2. Prevention of Material Corrosion: An isolation layer between the flexible inner sleeve and the flexible outer cylinder effectively prevents surface adhesion or swelling caused by contact between the two, avoiding corrosion-like phenomena and significantly extending the equipment's service life. Specifically, the isolation layer is made of a sponge of a certain thickness. Utilizing the sponge's deformability and resilience, its thickness changes when the flexible outer cylinder is compressed, assisting the flexible inner sleeve in its deformation. After the compression is released, the sponge returns to its original shape, re-supporting the inner surface of the flexible outer cylinder and maintaining its preset shape.

[0023] 3. This structure not only effectively improves comfort and stimulation intensity, but also prevents material interactions by introducing appropriate isolation layers, ensuring the durability and reliability of the device.

[0024] Therefore, with the above improvements, this utility model can not only provide necessary psychological support to help patients better cope with tension by designing an isolation structure between the flexible inner sleeve and the flexible outer sleeve, but also improve the collection effect through its own physical stimulation, effectively enhance the overall user experience, and extend the service life of the device.

[0029] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Please see Figures 1 to 5 In this embodiment of the present invention, a flexible multilayer structure for preventing corrosion includes a flexible inner sleeve 10 and a flexible outer cylinder 20, both made of flexible materials. The flexible outer cylinder 20 is fitted onto the outer surface of the flexible inner sleeve 10, so that when the flexible outer cylinder 20 is deformed by external force, it causes the flexible inner sleeve 10 to deform synchronously, changing the shape of the internal accommodating space of the flexible inner sleeve 10. An isolation layer 30 is provided in the space between the flexible inner sleeve 10 and the flexible outer cylinder 20. One side of the isolation layer 30 abuts against the outer surface of the flexible inner sleeve 10, and the other side abuts against the inner surface of the flexible outer cylinder 20, thereby isolating the flexible inner sleeve 10 and the flexible outer cylinder 20 from each other.

[0031] Specifically, during the use of sperm collection equipment, patients may experience anxiety, leading to prolonged inability to ejaculate sperm and collection failure. To optimize the sperm collection process, sperm collection auxiliary equipment or devices can be made of flexible materials, allowing patients to squeeze the flexible multi-layered structure to alleviate their anxiety and assist in the ejaculation and collection process.

[0032] Secondly, existing sperm collection equipment may not provide sufficient stimulation, making it difficult for some insensitive patients to complete the collection process smoothly. However, with a flexible multi-layered structure, the patient's own movements can compress the flexible material, causing deformation of the inner sleeve 10, enhancing ejaculation stimulation and assisting in the successful collection process. However, due to the contact and even deformation between the flexible inner sleeve 10 and the flexible outer sleeve 20, surface adhesion or swelling can easily occur between them, similar to corrosion, affecting their lifespan.

[0033] Furthermore, by setting the isolation layer 30, a separation can be formed between the flexible inner sleeve 10 and the flexible outer sleeve 20, preventing surface adhesion or swelling after they come into contact with each other, avoiding corrosion-like phenomena, and thus improving their service life.

[0034] In another embodiment, such as Figure 2 and Figure 3 As shown, preferably, the flexible inner sleeve 10 is made of thermoplastic elastomer material, and the flexible outer sleeve 20 is made of silicone material.

[0035] Specifically, thermoplastic elastomers (TPEs) are materials that combine the high elasticity of rubber with the processing properties of thermoplastic plastics. They are primarily composed of various polymers, such as styrene-based block copolymers and thermoplastic polyurethanes. They also exhibit a wide hardness range, typically from 0A to 100A, with the softest reaching 000 or even 00000 degrees. To enhance the softness of the flexible inner sleeve 10 and make it more closely resemble the texture of human skin, the flexible inner sleeve 10 can utilize ultra-soft TPEs with a hardness below 0A (such as 000 or even 00000).

[0036] Secondly, silica gel is a highly active adsorbent material and an amorphous substance. Its chemical composition is silicon dioxide (SiO2) and water (H2O), making it an inert material. Its hardness is generally between 20 and 90 degrees (Shore hardness). Although silica gel can be made relatively soft, its softness is usually not as good as TPE under the same visual appearance. Therefore, silica gel can be used to make flexible outer cylinders 20, making them more supportive while also allowing them to deform under pressure and return to their original shape after the pressure is released.

[0037] Secondly, prolonged contact between TPE and silicone may lead to surface changes, such as surface adhesion or discoloration. For example, when TPE and silicone are in close contact for an extended period at high temperatures, slight interpenetration may occur due to the microscopic movement of the molecular chains. Furthermore, some TPE materials may contain small amounts of plasticizers and other additives. Under prolonged use or specific environmental conditions, these additives may migrate to the silicone surface, causing changes in the silicone's surface properties, such as softening or slight swelling, affecting the user experience and even reducing its lifespan.

[0038] In another embodiment, such as Figures 2 to 5 As shown, preferably, the isolation layer 30 is made of polytetrafluoroethylene film material, thereby separating the flexible inner sleeve 10 and the flexible outer cylinder 20 from each other.

[0039] Specifically, the isolation layer 30 can be made of polytetrafluoroethylene (PTFE) film material, which has excellent chemical stability, low coefficient of friction, and non-stick properties. Placing the PTFE film between the TPE and silicone effectively prevents direct contact between the two, preventing adhesion or swelling. Its special surface structure makes it difficult for molecules to adhere, thus providing excellent isolation.

[0040] In another embodiment, such as Figures 2 to 5 As shown, preferably, the isolation layer 30 is made of polyethylene film material, thereby separating the flexible inner sleeve 10 and the flexible outer sleeve 20 from each other.

[0041] Specifically, the separator 30 can be made of polyethylene (PE) film, a common plastic material with good flexibility and chemical stability. PE film can serve as an economical separator between TPE and silicone. It reduces the contact area between the two, lowering the possibility of adhesion or swelling.

[0042] In another embodiment, such as Figures 2 to 5 As shown, preferably, the isolation layer 30 is a silicone coating, thereby separating the flexible inner sleeve 10 from the flexible outer sleeve 20.

[0043] Specifically, a silicone coating can be applied to the surface of TPE or silicone to form a smooth surface with low surface energy, thus preventing adhesion between the two. Silicone coatings offer excellent heat resistance, cold resistance, and weather resistance, maintaining stable performance under various environmental conditions.

[0044] In another embodiment, such as Figures 2 to 5As shown, preferably, the isolation layer 30 is made of sponge material, thereby separating the flexible inner sleeve 10 and the flexible outer cylinder 20 from each other.

[0045] Specifically, adding sponge can provide a certain degree of physical isolation between TPE and silicone materials. Sponge is a porous material that can form a barrier between the two, reducing the direct contact area between TPE and silicone. For example, when certain additives in TPE (such as plasticizers) tend to migrate into silicone, the sponge can hinder this migration process, thereby reducing the likelihood of silicone swelling to some extent.

[0046] Secondly, regarding the issue of surface adhesion, the presence of the sponge can prevent the interpenetration of molecular chains between TPE and silicone due to prolonged close contact. Because intermolecular interactions (such as van der Waals forces) weaken rapidly with increasing distance, the sponge effectively reduces these intermolecular forces that cause adhesion by separating them at a certain distance.

[0047] Secondly, sponges come in different materials, such as polyurethane sponges. If the chosen sponge material is chemically stable and does not adsorb or react with the components of TPE and silicone, it can better perform its insulating function. For example, some specially treated fire-retardant sponges have relatively stable chemical structures and will not introduce new interfering factors that could cause material problems when isolating TPE and silicone.

[0048] In another embodiment, such as Figures 2 to 5 As shown, preferably, the isolation layer 30 is a sponge with a certain thickness, so that the flexible inner sleeve 10 and the flexible outer sleeve 20 are separated from each other.

[0049] Specifically, since the flexible inner sleeve 10 and the flexible outer cylinder 20 may undergo compression deformation, it is preferable to set the isolation layer 30 as a sponge with a certain thickness. Utilizing the deformable and resilient properties of the sponge, the compression deformation of the flexible outer cylinder 20 can both change the thickness of the sponge to assist the deformation of the flexible inner sleeve 10, and allow the sponge to restore its original shape after the compression action is released, which is equivalent to restoring the inner surface of the flexible outer cylinder 20, so that the flexible outer cylinder 20 maintains the preset shape, improves its performance, and extends its service life.

[0050] In another embodiment, such as Figures 2 to 5 As shown, preferably, the two ends of the flexible outer cylinder 20 are detachably fixed to the two ends of the flexible inner sleeve 10.

[0051] Specifically, to facilitate assembly, disassembly, and cleaning, existing snap-fit ​​structures 40 can be installed at both ends of the flexible outer cylinder 20 and the flexible inner sleeve 10, allowing the flexible outer cylinder 20 to be detachably connected to both ends of the flexible inner sleeve 10 via the snap-fit ​​structures 40. Furthermore, after prolonged use, the sponge-material isolation layer 30 may lose some of its resilience or its thickness may decrease; therefore, the flexible outer cylinder 20 can be disassembled to replace the isolation sponge.

[0052] In another embodiment, such as Figures 2 to 5 As shown, preferably, the two ends of the flexible outer cylinder 20 are glued to the two ends of the flexible inner sleeve 10 by an adhesive process.

[0053] Specifically, to simplify the production process, the two ends of the flexible outer cylinder 20 can be directly bonded to the two ends of the flexible inner sleeve 10. Understandably, before bonding, an isolation layer 30 needs to be placed between the flexible outer cylinder 20 and the flexible inner sleeve 10.

[0054] In addition, end caps 50 can be provided at both ends of the flexible outer cylinder 20. The end caps 50 can be used to cover both ends of the flexible outer cylinder 20 and cover and protect both ends of the flexible inner sleeve 10, making it easy to store, package or transport.

[0055] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
