Description

Technical Field

[0001] This utility model relates to the technical field of sperm collection equipment, and in particular to an optimized structure that causes negative pressure deformation of flexible materials. Background Technology

[0002] In the field of sperm collection equipment, current technologies have certain limitations in meeting the diverse needs of patients. Especially for male patients with low ejaculation ability, improving collection efficiency and enhancing patient comfort has always been a key focus in the medical and medical device fields.

[0003] Currently, common sperm collection devices typically use flexible materials to create a sleeve (such as a silicone sleeve) to assist patients in completing the semen extraction process. To further improve collection efficiency, some devices are also equipped with components that have vibration or heating functions, using physical stimulation to assist patients in completing the semen extraction process, thereby increasing collection speed and user comfort.

[0004] However, for some less sensitive patients, these existing auxiliary methods still have certain limitations. On the one hand, the traditional sperm collection process is relatively lengthy, and patients have to endure considerable physical and mental stress throughout the process, which can easily lead to physical and mental fatigue and affect the smooth progress of the collection. On the other hand, although existing technologies have solutions to improve the binding force by modifying the insertion part, such as having the user hold the outer shell containing the internal components to adjust the binding force, this method has obvious drawbacks. In fact, this method cannot effectively adjust the binding force of a semen collector; its adjustment capability is relatively small, or it requires the patient to hold the outer shell to adjust it, which to some extent distracts the patient's attention, reduces sensory stimulation, and is not conducive to the patient's full engagement in the sperm collection process, seriously affecting collection efficiency and patient experience.

[0005] For example, Chinese patent document CN113729783A discloses a semen collector capable of adjusting the binding force and with good operability. A rotating handle integrated with the built-in components can rotate around an axial center. By rotating the handle, the built-in components and the insertion part twist in the same direction as the handle, thus enhancing the binding force compared to the usual state and allowing for easy adjustment of the insertion part's binding force. While it allows for easy adjustment of the binding force, the aforementioned problems still exist.

[0006] Therefore, existing sperm collection equipment still needs further improvement and refinement in terms of increasing collection efficiency and improving the user experience for insensitive patients. There is an urgent need for a technical solution that can more effectively assist men with low ejaculatory ability to successfully complete ejaculation, improve collection efficiency, and reduce the physical and mental fatigue of patients. Utility Model Content

[0007] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0008] This invention provides an optimized structure for generating negative pressure deformation in flexible materials, comprising a flexible body made of flexible material and a negative pressure device. One end of the flexible body serves as an accessory end, on which a functional accessory is installed, and the other end is an open end. An insertion port is provided at the open end, and an insertion part is formed therein. The insertion part has a cylindrical space extending a certain depth from the insertion port into the interior of the flexible body. The negative pressure device includes a negative pressure generator and a negative pressure deformation part. The negative pressure generator is installed at the accessory end, and the negative pressure deformation part is installed on the flexible body at a position corresponding to the side wall of the cylindrical space, thereby causing a certain deformation of the side wall of the cylindrical space, thus changing the shape or volume of the cylindrical space.

[0009] Furthermore, the negative pressure device is also equipped with an air passage hose, one end of which is connected to the negative pressure generating port of the negative pressure generator, and the other end is connected to the negative pressure deformation section, so that the negative pressure deformation section generates a negative pressure area, thereby driving the side wall of the cylindrical space to deform.

[0010] Furthermore: the negative pressure generator is set as a miniature negative pressure pump, and one end of the air hose is connected to the air intake port of the miniature negative pressure pump.

[0011] Furthermore: the negative pressure deformation section is provided with a negative pressure box, one side of which is open, and a deformation cavity is formed inside the negative pressure box. The deformation cavity is connected to the air passage hose.

[0012] Furthermore, the negative pressure deformation section is also equipped with an auxiliary component, which is placed inside the deformation cavity of the negative pressure box to isolate the air hose from the flexible body.

[0013] Furthermore, the auxiliary components are made of a flexible, porous, elastic material.

[0014] Furthermore, the auxiliary components are made of sponge material.

[0015] Furthermore, one end of the negative pressure chamber is provided with a U-shaped notch for installing an air hose.

[0016] Furthermore: The inner wall of the negative pressure box with a U-shaped notch is provided with an L-shaped edge strip, and a limiting groove is formed between the L-shaped edge strip and the side wall of the negative pressure box. A limiting insert is provided in the limiting groove, and the limiting insert has a through hole through which the air supply hose passes, and forms a detachable fixed connection with the limiting groove. Furthermore, one end of the limiting insert is also equipped with a baffle, the extension direction of which is consistent with the installation direction of the air hose.

[0017] Compared with the prior art, the beneficial effects of this utility model are: This invention addresses the shortcomings of existing technologies by proposing an optimized structure that induces negative pressure deformation in flexible materials. When applied to sperm collection equipment, it offers the following significant advantages: 1. By setting a negative pressure deformation section inside the side wall of the insertion part, and using a negative pressure generator to drive the negative pressure deformation section to form a negative pressure area, a negative pressure adsorption is formed on the side wall of the cylindrical space, causing it to deform uniformly. This changes the shape or volume of the cylindrical space, resulting in a stronger binding force on the insertion part. This enhanced binding force helps to stimulate insensitive patients, improve their sensory stimulation, and thus assist patients in improving collection efficiency and reducing collection time.

[0018] 2. The negative pressure adsorption effect causes deformation of the sidewalls of the cylindrical space, creating a suction effect. This enhances the sensory stimulation intensity for insensitive patients, helping them to better cooperate with the collection process, reducing psychological burden, and improving the success rate of collection.

[0019] 3. Quiet and Comfortable: The auxiliary components are made of sponge material, which not only has good elasticity and softness, allowing it to work normally under negative pressure and assist the flexible body in rebounding, but also has excellent sound absorption and noise reduction effects. During the air extraction process of the airway hose, the sponge material can reduce noise, creating a relatively quiet and comfortable usage environment for patients, further enhancing their user experience.

[0020] 4. The auxiliary components effectively isolate the air hose from the flexible body, preventing the flexible material of the flexible body from being adsorbed onto the air hose inlet, which could cause blockage. This ensures that the air hose can draw air normally, allowing the negative pressure state to be generated continuously and stably, thus ensuring the reliability and stability of the entire device.

[0021] With the above improvements, this optimized structure features a negative pressure deformation section on the side wall of the insertion part. The negative pressure generator deforms the side wall of the cylindrical space, enhancing the binding force, increasing sensory stimulation for insensitive patients, assisting in semen collection, and improving collection efficiency. The auxiliary components prevent blockage and reduce noise, ensuring a stable and reliable structure, guaranteeing stable and efficient system operation, improving patient experience, reducing costs, and enhancing overall experience.

Detailed Implementation

[0026] 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.

[0027] Please see Figures 1 to 7In this embodiment of the present invention, an optimized structure for generating negative pressure deformation of a flexible material includes a flexible body 10 made of flexible material and a negative pressure device 50. One end of the flexible body 10 serves as an accessory end 11, on which a functional accessory is installed, and the other end is set as an open end 20. An insertion port 21 is provided in the open end 20, and an insertion part 22 is formed therein. The insertion part 22 has a cylindrical space 30 extending a certain depth from the insertion port 21 into the interior of the flexible body 10. The negative pressure device 50 is provided with a negative pressure generator 52 and a negative pressure deformation part 53. The negative pressure generator 52 is installed in the accessory end 11, and the negative pressure deformation part 53 is installed on the flexible body 10 at a position corresponding to the side wall of the cylindrical space 30, and drives the side wall of the cylindrical space 30 to generate a certain deformation, thereby changing the shape or volume of the cylindrical space 30.

[0028] Specifically, some sperm collection devices often incorporate flexible sheaths, such as silicone sheaths, to improve collection speed and patient comfort, assisting patients in the semen extraction process. To further enhance efficiency, vibration or heating components are also typically installed to aid in the collection process. However, for some less sensitive patients, the process can still be relatively lengthy and lead to physical and mental fatigue.

[0029] Existing technologies have also improved the insertion part 22 to increase its binding force, which can promote ejaculation in men with low ejaculatory ability. For example, the user can adjust the binding force by gripping the outer shell containing the internal components during use. However, this cannot be used to adjust the binding force of a semen collector. Either its adjustment capability is relatively small, or the patient needs to hold the outer shell to adjust it, which to some extent reduces the patient's sensory stimulation and makes it difficult for the patient to successfully complete the sperm collection process.

[0030] Therefore, improvements are necessary. This application addresses this by providing a negative pressure deformation section 53 within the side wall of the insertion section 22. The negative pressure generator 52 can drive the negative pressure deformation section 53 to form a negative pressure region, creating negative pressure adsorption on the side wall of the cylindrical space 30, causing corresponding deformation. This alters the shape or volume of the cylindrical space 30, resulting in a stronger binding force on the insertion section 22, increasing sensory stimulation for insensitive patients, assisting them in improving collection efficiency, reducing collection time, and alleviating physical and mental fatigue. The optimized structure of this invention can be used as part of a device to assist men in collecting sperm, enabling medical purposes to help men with low ejaculation ability to successfully complete ejaculation and achieve the goal of sperm collection.

[0031] Secondly, some devices in the industry also use negative pressure generator 52, where the air intake of the extraction pipe is directly inserted into the cylindrical space 30 of the insertion part 22. Although this can effectively extract air from the cylindrical space 30 and create a negative pressure effect, it can also easily lead to the extraction of other liquids inside the cylindrical space 30, such as lubricating oil. These liquids are then discharged through the air outlet of the negative pressure generator 52 into the flexible body 10 or the parts box 40, causing leakage in the flexible body 10 or affecting the normal operation of the components in the parts box 40, seriously affecting the service life of the equipment.

[0032] This optimized structure has been improved by placing the negative pressure deformation part 53 inside the flexible body 10 and maintaining a non-permeable state with the cylindrical space 30, fundamentally eliminating the possibility of liquid being drawn out from the cylindrical space 30, thus preventing leakage. Furthermore, a negative pressure chamber 60 is innovatively set inside the side wall of the cylindrical space 30, allowing the side wall of the cylindrical space 30 to deform into the deformation cavity 54 of the negative pressure chamber 60, thereby indirectly changing the shape or volume of the cylindrical space 30 to achieve a suction effect, assisting insensitive patients and improving collection efficiency.

[0033] A sponge is also placed inside the negative pressure chamber 60 to separate the flexible material of the flexible body 10 from the rigid material of the negative pressure chamber 60, preventing the flexible material from deforming under negative pressure and sticking to the rigid material. At the same time, the porous structure of the sponge can also be used to prevent the flexible material from clogging the air inlet of the air passage hose 51, so that the negative pressure state inside the entire negative pressure chamber 60 is relatively balanced, improving the deformation effect.

[0034] like Figures 1 to 6 As shown, preferably, the negative pressure device 50 also includes an air passage hose 51. One end of the air passage hose 51 is connected to the negative pressure generating port of the negative pressure generator 52, and the other end is connected to the negative pressure deformation section 53, so that the negative pressure deformation section 53 generates a negative pressure area, thereby driving the sidewall of the cylindrical space 30 to deform. The negative pressure generator 52 is configured as a miniature negative pressure pump, and one end of the air passage hose 51 is connected to the air intake port of the miniature negative pressure pump.

[0035] Specifically, in order to generate negative pressure, it is preferable to install a miniature negative pressure pump in the parts box 40 and connect the miniature negative pressure pump to the negative pressure box 60 using an air hose 51, so that the negative pressure pump can draw air from the negative pressure box 60, so that a negative pressure area is formed in the deformation cavity 54, which can adsorb the flexible body 10, especially the side wall of the adsorption cylindrical space 30, causing the side wall to deform and produce a suction effect.

[0036] like Figures 1 to 3As shown, preferably, the negative pressure deformation part 53 is provided with a negative pressure box 60, one side of the negative pressure box 60 is open, and a deformation cavity 54 is formed inside the negative pressure box 60. The deformation cavity 54 is in a state of air passage communication with the air passage hose 51.

[0037] Specifically, the airway hose 51 is connected to one end of the negative pressure deformation section 53 and inserted into the negative pressure chamber 60, thereby drawing air out of the deformation cavity 54 and creating a negative pressure state inside the deformation cavity 54. This creates a negative pressure adsorption effect on the side wall of the cylindrical space 30, causing the side wall of the cylindrical space 30 to extend from the opening into the deformation cavity 54 and undergo corresponding deformation. This changes the shape or volume of the cylindrical space 30, producing a suction effect, enhancing the sensory stimulation intensity of insensitive patients, and assisting them in successfully completing the semen collection process.

[0038] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, preferably, the negative pressure deformation part 53 is also provided with an auxiliary component 55, which is placed in the deformation cavity 54 of the negative pressure box 60 to isolate the air hose 51 from the flexible body 10.

[0039] Specifically, during the process of generating negative pressure by drawing air, the flexible material of the flexible body 10 is easily adsorbed onto the inlet of the air hose 51, causing blockage and affecting its smooth air extraction. This results in insufficient negative pressure or an excessively small negative pressure area, affecting the deformation state of the sidewall of the cylindrical space 30. Therefore, an auxiliary component 55 can be installed inside the deformation cavity 54 to isolate the air hose 51 from the flexible body 10, allowing the air hose 51 to function normally.

[0040] In another embodiment, preferably, the auxiliary component 55 is made of a flexible porous elastic material.

[0041] Specifically, since the air hose 51 needs to continue drawing air under the deformation pressure of the auxiliary component 55, the auxiliary component 55 is preferably made of a flexible, porous elastic material, which allows it to deform under certain pressure and maintain airflow during deformation, thus ensuring the continuous generation of negative pressure. After the negative pressure is released, the auxiliary component 55 can also use its elasticity to return to its original shape, while simultaneously creating a compression and rebound effect on the sidewall of the cylindrical space 30, allowing the flexible body 10 on the sidewall to return to its original shape normally.

[0042] Secondly, flexible porous elastic materials can be made from the following materials: Polyurethane foam is a common foam material made from expanded polyurethane. It has a rich pore structure, exhibiting porous characteristics. It also possesses a degree of elasticity, allowing it to withstand pressure within a certain range and return to its original shape. The pores inside polyurethane foam are interconnected, forming a continuous network of gas channels, which allows air to circulate freely between the pores.

[0043] Rubber sponge: A sponge-like material with a porous structure, made from rubber as the base material through a special process. The inherent elasticity and flexibility of rubber give rubber sponges excellent elasticity and resilience, allowing them to maintain good performance under various external forces. The porous structure inside the rubber sponge allows air circulation; during the manufacturing process, many independent or interconnected air chambers are formed, with tiny channels between these chambers allowing air to flow.

[0044] EVA foam: A foam material made of ethylene-vinyl acetate copolymer (EVA). It is lightweight, soft, and elastic, with numerous tiny pores forming a porous structure. These tiny pores within EVA foam are generally interconnected, allowing air to circulate within them.

[0045] In yet another embodiment, preferably, the auxiliary component 55 is made of sponge material.

[0046] Specifically, the auxiliary component 55 is made of natural or synthetic sponge. Adding sponge as the auxiliary component 55 increases resilience, assisting the flexible body 10 in rebounding after deformation; it also creates a sound-absorbing and noise-reducing effect, lowering the noise of the air hose 51 drawing air, achieving a quieter operation and improving the user experience. Furthermore, the sponge has excellent elasticity and softness, capable of significant deformation under external force and quickly returning to its original shape after the force disappears. This characteristic allows the sponge to provide comfortable support and cushioning when in contact with the human body. Installing it within the deformation cavity 54, assisting the sidewalls of the cylindrical space 30 in deformation, can make people feel comfortable and relaxed.

[0047] Secondly, natural sponges are marine organisms that have undergone processing. Their internal pore structure is unique, irregular, and diverse, with relatively natural pore size and distribution. Synthetic sponges, on the other hand, are made using chemical methods to mimic the structure and properties of natural sponges. Their pore structure is relatively more regular, but can still be adjusted to meet specific needs. The pores of sponges generally have good connectivity, allowing air and water to flow smoothly within them. This connectivity gives sponges excellent breathability and absorbency.

[0048] In addition, sponges are relatively inexpensive, especially natural sponges. Although the production cost of synthetic sponges may fluctuate due to factors such as raw material prices and production processes, overall, sponges are relatively affordable, which has led to their widespread use in many fields.

[0049] like Figure 6 As shown, preferably, one end of the negative pressure box 60 is provided with a U-shaped notch 61 for installing the air hose 51.

[0050] Specifically, in order to install the air hose 51, a U-shaped notch 61 can be provided at one end of the negative pressure box 60 so that the air hose 51 can be inserted into the notch, preventing the side wall of the negative pressure box 60 from pressing the hose and affecting the airflow.

[0051] like Figure 3 , Figure 4 and Figure 6 As shown, preferably, the negative pressure box 60 has an L-shaped side strip 62 on the inner side wall of the U-shaped notch 61. The L-shaped side strip 62 and the side wall of the negative pressure box 60 form a limiting groove 63. A limiting insert 64 is provided in the limiting groove 63. The limiting insert 64 has a through hole 41 through which the air supply hose 51 passes and forms a detachable fixed connection with the limiting groove 63.

[0052] Specifically, to further secure the air hose 51, an L-shaped strip 62 can be provided on the side wall corresponding to the limiting notch, and the L-shaped strip 62 also has a U-shaped notch 61 to facilitate the installation of the air hose 51. A limiting groove 63 can be formed between the L-shaped strip 62 and the side wall of the negative pressure box 60, so that the limiting insert 64 through which the air hose 51 passes can be inserted into the limiting groove 63 and form an interference fit or a snap-fit ​​connection, thereby stably fixing the air hose 51 in the U-shaped notch 61 of the negative pressure box 60.

[0053] like Figure 3 , Figure 4 and Figure 6 As shown, preferably, one end of the limiting insert 64 is also provided with a baffle 65, and the extension direction of the baffle 65 is consistent with the installation direction of the air hose 51.

[0054] Specifically, to facilitate the installation of the limiting insert 64, a baffle 65 perpendicular to the limiting insert 64 can be provided on one side. During installation, the baffle 65 can be held to insert the limiting insert 64 into the limiting groove 63. Moreover, the baffle 65 is located at the end of the limiting insert 64 corresponding to the opening of the U-shaped notch 61, thereby blocking the installed air hose 51 and preventing the air hose 51 from being squeezed and deformed at the opening of the notch, thus affecting the airflow.

[0055] like Figure 5 and Figure 7 As shown, preferably, to facilitate the installation of functional accessories, a tail cap 42 and a parts box 40 are typically provided on the accessory end 11 of the equipment or container. Corresponding functional components are installed inside the parts box 40, which can be embedded in a groove on the accessory end 11. The tail cap 42 preferably covers the opening of the parts box 40, and the negative pressure generator 52 is disposed inside the parts box 40. To protect the components, the parts box 40 and tail cap 42 are preferably made of relatively hard materials, such as hard plastics, i.e., common thermosetting plastics, such as phenolic plastics, epoxy plastics, amino plastics, unsaturated polyesters, alkyd plastics, etc. Similarly, the negative pressure chamber 60 is preferably made of a relatively hard material to form a stable deformation cavity 54.

[0056] Secondly, the bottom of the parts box 40 is also provided with a through hole 41, allowing the air hose 51 to pass through the through hole 41, thereby connecting the negative pressure generator 52 inside the parts box 40 with the negative pressure deformation part 53 inside the flexible body 10. Other corresponding functional components, such as vibrators and heaters, can also be installed inside the parts box 40 as needed, and corresponding buttons 43 are provided on the tail cover 42 to control the functional components.

[0057] The optimized structure proposed in this application, which induces negative pressure deformation in flexible materials, has significant advantages over existing technologies, effectively solves the aforementioned technical problems, and brings multifaceted improvements to sperm collection equipment.

[0058] By innovatively incorporating a negative pressure deformation section 53 within the sidewall of the insertion portion 22, and in conjunction with a negative pressure generator 52, the negative pressure generator 52 drives the negative pressure deformation section 53 to form a negative pressure area. This creates negative pressure adsorption on the sidewall of the cylindrical space 30, causing corresponding deformation of the sidewall and altering the shape or volume of the cylindrical space 30. This design provides stronger binding force to the insertion portion 22, significantly enhancing sensory stimulation for insensitive patients. For men with low ejaculatory capacity, this enhanced binding force better simulates physiological stimulation, assisting patients in improving collection efficiency, significantly reducing collection time, and effectively alleviating physical and mental fatigue during the collection process.

[0059] Specifically, the air hose 51 in the negative pressure device 50 is connected at one end to the negative pressure generating port of the negative pressure generator 52 and at the other end to the negative pressure deformation section 53, ensuring stable transmission of negative pressure and enabling the negative pressure deformation section 53 to reliably generate a negative pressure area, driving the sidewall of the cylindrical space 30 to deform precisely. The negative pressure generator 52 uses a miniature negative pressure pump, which has the advantages of small size, low energy consumption, and high negative pressure generation efficiency, and can meet the equipment's requirements for portability and high efficiency.

[0060] The negative pressure chamber 60 of the negative pressure deformation section 53 corresponds to the side wall of the cylindrical space 30 through an opening on one side. The deformation cavity 54 formed inside is connected to the air passage hose 51. The air passage hose 51 draws air from the deformation cavity 54, creating a negative pressure state inside the cavity. This creates a negative pressure adsorption effect on the side wall of the cylindrical space 30, causing the side wall to extend from the opening into the deformation cavity 54 and deform, producing a suction effect. This further enhances the sensory stimulation intensity for insensitive patients, effectively assisting them in successfully completing the semen collection process.

[0061] The auxiliary component 55, installed in the negative pressure deformation section 53, is made of a flexible porous elastic material (such as sponge material) and has multiple functions. On the one hand, the auxiliary component 55 can effectively isolate the air hose 51 from the flexible body 10, preventing the flexible material of the flexible body 10 from adsorbing onto the inlet during the process of generating negative pressure by the air hose 51, ensuring the normal operation of the air hose 51, ensuring sufficient negative pressure and stable negative pressure area, thereby ensuring the deformation effect of the side wall of the cylindrical space 30. On the other hand, after the negative pressure is released, the auxiliary component 55 can use its own elasticity to restore its original shape, while simultaneously creating a compression and rebound effect on the side wall of the cylindrical space 30, helping the flexible body 10 on the side wall to quickly and normally restore its original shape.

[0062] Furthermore, using sponge as an auxiliary component 55 increases resilience, further assisting the flexible body 10 in rebounding after deformation; the porous structure of the sponge can create a sound-absorbing and noise-reducing effect, reducing the noise generated when the air hose 51 draws air, creating a quiet operating environment and improving the user experience. Moreover, sponge materials are relatively inexpensive; whether natural or synthetic sponge, they reduce the manufacturing cost of the equipment while ensuring performance, which is conducive to the promotion and application of the product.

[0063] In the installation design of the negative pressure chamber 60, a U-shaped notch 61 is provided at one end to facilitate the installation of the air hose 51, effectively preventing the side wall of the negative pressure chamber 60 from compressing the hose and affecting airflow. An L-shaped strip 62 is provided on the inner side wall of the U-shaped notch 61, forming a limiting groove 63 between the L-shaped strip 62 and the side wall of the negative pressure chamber 60. A limiting insert 64 is provided in the limiting groove 63, and the limiting insert 64 has a through hole 41 for the air hose 51 to pass through. The limiting insert 64 is detachably fixed to the limiting groove 63 by means of interference fit or snap connection, which further stabilizes the air hose 51. The baffle 65 provided at one end of the limiting insert 64 extends in the same direction as the installation direction of the air hose 51 and is located at the opening end of the U-shaped notch 61. This facilitates the installation of the limiting insert 64 and also provides protection for the air hose 51, preventing it from being squeezed and deformed at the notch opening, ensuring smooth airflow, and thus ensuring the stable and efficient operation of the entire negative pressure deformation system.

[0064] 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.
