TECHNICAL FIELD
[0001] The present application relates to the technical field of medical equipment, in particular to a flexible extrusion type sperm collection device for reproductive medicine. BACKGROUND
[0002] In assisted reproduction and andrology diagnosis, the collection quality of semen samples directly affects the detection results and treatment success rate. The commonly used collection method in clinical practice is manual or device-assisted sperm collection, and the semen is stored in a standard wide-mouth glass or plastic cup.
[0003] Most of the existing sperm collection devices on the medical market have complex internal structures (such as folds and dead angles) or cavity transition zones at the connection of the collection container during actual use, which causes the semen, especially the viscous part, to be left over, resulting in sample loss and measurement errors. In addition, the complex internal channels or elastic structures designed to provide stimulation are extremely difficult to clean and disinfect thoroughly, posing a risk of cross-infection. After collection, the sample needs to be transferred from one container to another standard detection container, increasing the operation steps, contamination risk, and sample exposure time. Therefore, there is an urgent need for a sperm collection device that can achieve full-path unobstructed flow guidance, integrated collection, and easy replacement or cleaning of key contact components. SUMMARY
[0004] The present application discloses a flexible extrusion type sperm collection device for reproductive medicine, which aims to solve the technical problems of existing medical sperm collection devices on the market, which need to be improved in work perfection and operation convenience.
[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solutions: A flexible extrusion type sperm collection device for reproductive medicine, comprising a body, wherein the middle part of the body is provided with a collector with a built-in vibration motor, and a disposable utensil is inserted and installed inside the collector, the disposable utensil comprises a collection box for receiving semen, the end of the collection box is screw-mounted with a box cover, the middle part of the box cover is provided with a condom, the condom and the collection box are connected through, and the outer side of the condom is fixedly sleeved with a sealing tube, in normal state, the condom is in an outwardly bulging state and is compressed and limited by the sealing tube, and the condom naturally expanded without being blocked by external objects will be extruded and fitted with the inner wall of the collector.
[0006] This device, unlike traditional collection devices, incorporates disposable supplies into existing medical sperm collection equipment. During use, the patient inserts the disposable supplies into the collector. The supplies are already inside the collector, and a condom connected directly to the center of the lid maintains a relatively sealed environment. Sperm movement is limited to the condom and the collection box, minimizing exposure time and improving collection quality. The naturally expanding condom fits snugly against the inner wall of the collector, maximizing user comfort and preventing direct contact between the user and the reusable collector, significantly improving hygiene compared to traditional equipment.
[0007] In a preferred embodiment, a through groove is provided in the middle of the cover, and a molding groove is provided on the inner wall of the through groove. A fixing elastic band is provided at one end of the safety sleeve, and the fixing elastic band is locked inside the molding groove. A pair of sliding covers are slidably installed on both sides of the through groove. When the sliding covers move, they press and push against both sides of the fixing elastic band, causing the fixing elastic band to disengage from the inside of the molding groove. A closing elastic band is provided at the other end of the safety sleeve, and the closing elastic band is locked onto the outer end of the collector.
[0008] By incorporating a channel structure in the center of the lid to provide a flow path for sperm, and with the condom and lid quickly connected via a fixing elastic band and a molding groove, the sperm discharged by the user flows directly into the collection box through the condom and channel. Then, the sliding covers on both sides of the channel compress the condom, causing it to detach from the collection box and sealing it. This significantly improves the ease of operation, functionality, and quality of the collected sperm.
[0009] In a preferred embodiment, the periphery of the through groove is provided with a dotted line break, the dotted line break is connected and fixed to the sealing tube, the inside of the condom is provided with irregular threads, the inside of the collector is provided with a chamber, the disposable device is installed inside the chamber, and the internal shape of the chamber is customized according to requirements.
[0010] When prefabricating this disposable device, a dotted line break is set on the periphery of the through groove to connect to the sealing tube. After the disposable device is inserted into the collector using the sealing tube, the sealing tube can be quickly removed through the dotted line break, which greatly improves the convenience of using the device. At the same time, the chamber set inside the collector and the threads inside the condom can improve the user's comfort, thereby improving the working efficiency of the device.
[0011] As can be seen from the above, the elastic compression type sperm collection device for reproductive medicine provided by the present invention has the following technical effects.
[0012] Firstly, by incorporating disposable devices into existing medical sperm collection equipment, this device differs from traditional collection devices. During actual use, the patient inserts the disposable device into the collector. The disposable device is already inside the collector, and a condom directly connected to the center of the lid maintains a relatively sealed environment, improving collection quality. Furthermore, the naturally expanding condom structure maximizes user comfort while preventing direct contact between the user and the reusable collector, significantly improving hygiene compared to traditional equipment.
[0013] Secondly, by setting a through groove structure in the middle of the box lid, the condom and the box lid are quickly connected to the outside of the through groove through a fixing rubber band and a molding groove. The sperm discharged by the user enters the inside of the collection box directly through the condom and the through groove. Then, the sliding cover set on both sides of the through groove squeezes the condom to disengage from the collection box and seal the collection box. This greatly improves the convenience, functionality and quality of the collected sperm during operation of the device. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0025] The elastic compression type sperm collection device disclosed in this invention is mainly used in scenarios where sperm is mechanically collected from doctors and patients.
[0026] Reference Figures 1 to 9 A flexible compression type sperm collection device for reproductive medicine includes a body 1. A collector 2 with a built-in vibration motor is installed in the middle of the body 1. A disposable device 3 is inserted into the inside of the collector 2. The disposable device 3 includes a collection box 4 for receiving semen. A box cover 5 is screwed onto the end of the collection box 4. A condom 6 is provided in the middle of the box cover 5. The condom 6 and the collection box 4 are connected through. A sealing tube 7 is fixed to the outside of the condom 6. Under normal conditions, the condom 6 is in an outwardly expanded state and is compressed and limited by the sealing tube 7. When the condom 6 is not obstructed and expands naturally, it will squeeze and adhere to the inner wall of the collector 2.
[0027] In this embodiment: The patient goes to the medical room to collect disposable device 3 and carries it to the designated semen collection room. After washing their hands, the patient tears off the outer packaging of disposable device 3 and inserts the disposable device 3 into the collector 2 by holding the sealing tube 7. The patient then rotates and pries the sealing tube 7 to remove it from the outside of the condom 6. The specific steps are shown in the attached figure. Figure 2 As shown; however, the condom 6, no longer restrained by the sealing tube 7, will expand along the inside of the collector 2, as detailed in the attached diagram. Figure 8 As shown; thereafter, the patient inserts his / her genitals into the condom 6 and the system automatically collects semen. The semen discharged by the patient will flow into the collection box 4 through the condom 6.
[0028] The outer side of the collection box 4 is provided with a threaded groove 401, and the box cover 5 is screwed onto the outer side of the collection box 4 through the threaded groove 401. The threaded groove 401 makes it convenient for doctors to close and open the collection box 4. Specifically, a dotted line break 801 is provided around the periphery of the through groove 8.

A fixing elastic band 10 is provided at one end of the condom 6. The fixing elastic band 10 is locked inside the molding groove 9. A pair of sliding covers 11 are slidably installed on both sides of the through groove 8. When the sliding covers 11 move, they press and push against both sides of the fixing elastic band 10, causing the fixing elastic band 10 to disengage from the inside of the molding groove 9.
[0030] During use, the patient's semen flows along the inside of the condom 6, through the groove 8, into the inside of the lid 5 and the collection box 4. After collecting the semen, the patient pulls the condom 6 with their hand to remove the condom 6 and the collection box 4 from the outside of the collector 2. At the same time, the patient pinches the two sliding covers 11 with their fingers and pushes the sliding covers 11 along the inside of the groove 8. The moving sliding covers 11 will squeeze the fixing elastic band 10 at the end of the condom 6, causing the fixing elastic band 10 to disengage from the inside of the molding groove 9, thereby detaching the condom 6 from the lid 5. At the same time, the sliding covers 11, which move in the center, will close on the outside of the groove 8, thus sealing the lid 5.
[0031] Among them, some of the collectors 2 have a double-ended port structure, and the collection box 4 that has completed the semen collection can be adapted and taken out according to the structure of the collector 2.
[0032] Reference Figures 2 to 4 , Figure 6 In a preferred embodiment, the other end of the condom 6 is provided with a drawstring elastic band 12, which is snapped onto the outer end of the collector 2. The end of the collector 2 is screwed with an outer sleeve 202, which is snapped onto the outside of the drawstring elastic band 12.
[0033] The patient rotates and bends the sealing tube 7 to remove it from the outside of the condom 6. Without the sealing tube 7, the condom 6 will expand along the inside of the collector 2. At this point, the patient needs to remove the outer sleeve 202 of the collector 2, and simultaneously attach and secure the elastic band 12 at the end of the condom 6 to the outside of the collector 2. After re-secureing the outer sleeve 202 to the outside of the elastic band 12, the condom can be used again. The specific usage procedure is attached. Figure 2 To be continued Figure 3 As shown.
[0034] ReferenceFigure 8 In a preferred embodiment, the condom 6 has an irregular thread 601 inside, the collector 2 has a chamber 201 inside, the disposable device 3 is installed inside the chamber 201, and the internal shape of the chamber 201 is customized according to the requirements. The chamber 201 adopts a near-human structure and, together with the irregular thread 601, improves the user's comfort. This is prior art and will not be described in detail.
[0035] Working principle: During use, the patient goes to the medical room to obtain disposable device 3 and carries it to the designated semen collection room. After washing their hands, the patient tears off the outer packaging of disposable device 3 and inserts it into the collector 2 while holding the sealing tube 7. The patient then rotates and bends the sealing tube 7, causing it to break along the dotted line 801. The sealing tube 7 is then removed from the outside of the condom 6. Without the sealing tube 7, the condom 6 expands along the inside of the collector 2, as shown in the attached diagram. Figure 8 As shown; at this time, the patient needs to remove the outer cover 202 of the collector 2, and at the same time, attach and fix the elastic band 12 at the end of the condom 6 to the outside of the collector 2, and then re-secure the outer cover 202 to the outside of the elastic band 12. The specific usage procedure is as follows: Figure 2 To be continued Figure 3 As shown, the patient then inserts their genitals into the condom 6 for automatic semen collection. The patient's semen flows along the inside of the condom 6, through the channel 8, into the lid 5 and collection box 4. After collection, the patient pulls the condom 6 to remove the condom 6 and collection box 4 from the outside of the collector 2. At the same time, the patient pinches the two sliding covers 11 with their fingers and pushes the sliding covers 11 along the inside of the channel 8. The moving sliding covers 11 will squeeze the fixing elastic band 10 at the end of the condom 6, causing the fixing elastic band 10 to disengage from the inside of the molding groove 9, thereby detaching the condom 6 from the lid 5. At the same time, the moving sliding covers 11 will close on the outside of the channel 8, thus sealing the lid 5. The patient then hands the collection box 4 to the doctor.
