Description

Technical Field

[0001] The present invention relates to the technical field of sperm sampling, in particular to a sperm sampling device for reproductive medicine. Background Art

[0002] In the reproductive medicine departments of major hospitals, the physical characteristics of male semen, sperm motility and concentration are the main criteria for male semen testing. Therefore, when examining male reproductive health, it is necessary to collect and analyze the semen so that the hospital can analyze the patient's root cause through semen. In the process from semen collection to examination, there are high requirements for the safety and effectiveness of sperm. At present, the general existing method of semen sampling is for patients to collect sampling tubes and perform self-sampling, which can easily cause sampling difficulties and a difficult sampling process, and can easily cause fatigue. In addition, the test tubes after sampling do not have a heat preservation function, and sperm are very sensitive to the external temperature. Using a single-layer sampling tube can easily reduce sperm activity.

[0003] Existing sperm sampling devices, such as a semen sampler with a constant temperature function provided by publication number CN118356216A, include a mounting tube, which is equipped with symmetrically distributed insulation plates through hinges, and the mounting tube is respectively clamped with a sampling tube for collecting semen and a disposable silicone funnel sleeved on the tube mouth of the sampling tube, the symmetrically distributed insulation plates are all equipped with electric heating tubes, and the symmetrically distributed clamping plates are all equipped with temperature sensors for real-time monitoring of the temperature of the sampling tube; this application monitors the temperature of the sampling tube in real time through the temperature sensor, and automatically controls the start and stop of the electric heating tube through the temperature sensor, so that the temperature of the sampling tube is maintained within the range of 25°C-35°C to ensure sperm activity; but since this application is only designed for temperature control in the sampling tube, although it can solve the problem that existing products do not have a heat preservation function, it still cannot solve the problem that existing products are difficult to sample and that long-term holding of the sampler easily causes fatigue, and the sampling efficiency is low.

By designing a negative pressure suction massage component, the air is sucked in by the contraction and expansion of the airbag combined with a telescopic air inlet pipe, so that a negative pressure suction effect is formed in the sampling tube to improve the sampling efficiency. In combination with a fixing seat that can be fixed on various planes and a connecting hose, fatigue caused by long-term hand holding is reduced; by designing a heat preservation component, the inside of the sampling tube is heated and insulated by arranging multiple layers of heating plates and heat preservation layers on the outside of the sampling tube to ensure sperm activity.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0023] The inventors have found that the current method of semen sampling is for patients to collect sampling tubes and perform self-sampling, which can easily cause sampling difficulties and a difficult sampling process, and can easily cause fatigue. In addition, the tubes after sampling do not have a heat preservation function, and sperm is very sensitive to external temperature. Using a single-layer sampling tube can easily cause sperm activity to decrease. Some existing devices have made some improvements in maintaining sperm activity, but they still cannot solve the problem of sampling difficulties in existing products, and the problem that the sampler may easily become tired when holding the device for a long time.

[0024] Based on the above findings, the present application proposes a sperm sampling device for reproductive medicine, which designs a negative pressure suction massage component, slides and squeezes the airbag through the sliding ring, or pulls the airbag to expand, and combines the on-off mechanism to draw air from the sampling tube, so that a negative pressure suction effect is formed in the sampling tube, which can absorb semen and prevent it from adhering to the tube mouth of the sampling tube, and combines the massage ring located inside the sliding ring to squeeze the silicone ring to massage the sampler, thereby improving the sampling efficiency. By using a connecting hose and a fixing seat to fix the device on other planes, the fatigue problem caused by holding the device for a long time can be reduced; an insulation component is designed, and the inside of the sampling tube is heated and insulated by setting structures such as an insulation layer, a heating plate and an insulation layer to ensure the activity of sperm entering the sampling tube; it has the advantages of high sampling efficiency, good sample preservation effect, easy use, strong comfort and simple structure.

[0025] See Figure 1-Figure 3 ,as well as Figure 14 The present application discloses a sperm sampling device for reproductive medicine, comprising a first shell 1, a second shell 2 and a base 3 connected to each other by threads, see Figure 10 The first shell 1 is made of a high-strength plastic or lightweight metal material. The first shell 1 can be regarded as a hollow cylindrical structure with no covers at both ends. A plurality of threaded groove structures are provided at both ends along the inner side wall of the first shell 1. A circular baffle structure is provided near one end. Four shell pipelines 101 are provided in the baffle structure. At the same time, two slide grooves 102 parallel to the central axis of the first shell 1 are provided at the end away from the baffle structure and on opposite sides. The second shell 2 is a hollow cylindrical structure with a cover at one end. The material of the second shell 2 is the same as that of the first shell 1. The uncovered end of the second shell 2 is provided with a raised threaded ring structure that cooperates with the threaded groove structure at one end of the first shell 1 near the annular baffle structure, so that the second shell 2 and the first shell 1 can be connected and fixed by threaded engagement. The base 3 is a hollow cylindrical structure without a cover of a certain thickness. In some embodiments, the outer wall and the inner wall of the base 3 are provided with a threaded ring structure. The threaded ring on the outer wall of the base 3 cooperates with the threaded groove at the end of the first shell 1 away from the second shell 2. At the same time, its inner wall is also connected to a fixing ring 301 through the threaded ring structure. The inner wall of the fixing ring 301 is provided with a threaded groove for installing the silicone ring 4. The silicone ring 4 can be inserted along the center of the fixing ring 301 and fixed in the base 3 by a threaded connection. When a sampler who needs to undergo a reproductive medical examination completes sampling using this device, the silicone ring 4 and the fixing ring 301 can be unscrewed from the base 3 to replace the new silicone ring 4. By setting fixing rings 301 with different inner diameters, silicone rings 4 of different diameters can be installed, thereby improving the scope of application of this device.

[0026] See Figure 4-Figure 6 ,as well as Figure 15 The first shell 1 is provided with a negative pressure suction massage component 6 for improving the sampling efficiency. The negative pressure suction massage component 6 includes a sliding ring 601 slidably arranged on the first shell 1. Figure 11 In some embodiments, the sliding ring 601 can be regarded as a three-layer hollow cylindrical structure as a whole. A slider 6011 capable of sliding along the slide groove 102 on the first shell 1 is provided between the outermost layer and the middle layer. A ring structure with a certain thickness is fixed between the innermost layer and the middle layer. One end of the ring structure and one end of the slider 6011 can form a relatively flat surface, and the surface is fixedly connected to one end of the airbag 602 provided in the first shell 1. During installation, the airbag 602 can be regarded as being sleeved on the outside of the silicone ring 4, and the end of the airbag 602 away from the sliding ring 601 is fixed to the base 3. Therefore, when the silicone ring 4 and the fixing ring 301 are replaced, the airbag 602 will not be affected. When the sliding ring 601 slides along the first shell 1, the airbag 602 can be squeezed or stretched. One end of the airbag 602 is provided with four sets of gas pipes evenly distributed along the circumference. Meanwhile, the annular structure of the sliding ring 601 is provided with four sets of exhaust pipes 603 and intake pipes 604. The gas pipes on the airbag 602 are inserted into the corresponding exhaust pipes 603 and intake pipes 604 to form a communication. When the airbag 602 is squeezed or stretched, gas can be transferred between the gas pipes and the exhaust pipes 603 or intake pipes 604. Each exhaust pipe 603 and intake pipe 604 is provided with an on-off mechanism 605 which can automatically switch on and off in conjunction with the contraction and expansion of the airbag 602. Figure 7-9 The on-off mechanism 605 includes an exhaust valve seat 6051 and an intake valve seat 6052 fixed to the exhaust pipeline 603 and the intake pipeline 604 at one end away from the airbag 602. The exhaust valve seat 6051 and the intake valve seat 6052 are tubular structures with an axial diameter at both ends larger than the axial diameter in the middle. The overall length of the intake valve seat 6052 is larger than the overall length of the exhaust valve seat 6051. At the same time, a telescopic sleeve 606 is sleeved on the intake valve seat 6052, and the end of the telescopic sleeve 606 away from the intake valve seat 6052 is connected to the shell pipeline 101 on the first shell 1, so that the intake pipeline 603 is connected to the sampling tube 5 located in the second shell 2 through the intake valve seat 6052, the telescopic sleeve 606 and the shell pipeline 101, and when the airbag 602 contracts or expands, the telescopic sleeve 606 can keep the intake valve seat 6052 and the shell pipeline 101 always connected; The on-off mechanism 605 has the same structural composition in the exhaust pipe 603 and the intake pipe 604, except that a first steel ball 6053 is provided at one end of the intake pipe 604 near the intake valve seat 6052, a first spring 6054 is fixed to the side of the first steel ball 6053 away from the intake valve seat 6052, and the other end of the first spring 6054 is fixed to the end of the intake pipe 604 near the airbag 602; at the same time, a second steel ball 6055 is provided at one end of the exhaust pipe 603 away from the exhaust valve seat 6051, a second spring 6056 is fixed to the side of the second steel ball 6055 away from the exhaust valve seat 6051, and the other end of the second spring 6056 is fixed to the end of the exhaust pipe 603 near the exhaust valve seat 6051. That is, the on-off mechanism 605 is arranged in completely opposite directions in the exhaust pipe 603 and the intake pipe 604; See again Figure 7 When the airbag 602 is squeezed, the first steel ball 6053, under the action of the gas in the airbag 602 being discharged outward, blocks the connection between the intake pipe 604 and the intake valve seat 6052. Then, the gas in the airbag 602 blows the second steel ball 6055 in the exhaust pipe 603 and squeezes the second spring 6056. At this time, it can be seen that the exhaust pipe 603 is connected to the outside through the exhaust valve seat 6051, thereby exhausting the gas in the airbag 602. Figure 6 When the airbag 602 is stretched by the sliding ring 601, the airbag 602 will first absorb some air from the outside through the exhaust pipe 603. At the same time, the second steel ball 6055 slides in the opposite direction under the action of the second spring 6056 and the external air, thereby blocking the connection between the exhaust pipe 603 and the airbag 602. At this time, the airbag 602 turns to attract the first steel ball 6053 in the air intake pipe 604 and squeeze the first spring 6054. At this time, it can be regarded as that the air intake pipe 604 is connected to the telescopic sleeve 606 and even to the inside of the sampling tube 5 through the air intake valve seat 6052. The airbag 602 can then extract the gas in the sampling tube 5, forming a negative pressure state inside the sampling tube 5, thereby generating a certain suction force on the body parts of the sampler, which can promote the discharge of semen, thereby effectively improving the sampling efficiency. It is worth mentioning that due to the overall size limitation of the sliding ring 601 and the first shell 1, the negative pressure generated inside the sampling tube 5 by the sliding ring 601 each time it slides back and forth is relatively small, so that the device can improve the sampling efficiency while not causing damage to the body parts of the sampler, thereby ensuring safety.

[0027] In some embodiments, a massage ring 607 with multiple protrusions is provided on the innermost side of the sliding ring 601. When the sliding ring 601 slides along the first shell 1, the massage ring 607 can squeeze the silicone ring 4, thereby squeezing and massaging the body parts of the sampler, which can improve the sampler's comfort during use, thereby further improving the sampling efficiency.

[0028] In some embodiments, a sealing ring 608 may be optionally provided at the connection between the second housing 2 and the first housing 1 , see Figure 12 The sealing ring 608 can be regarded as a double-layer annular structure with a cavity in the middle. A through hole is opened on the sealing ring 608 to allow the shell pipeline 101 of the first shell 1 to pass through. By setting the sealing ring 608, the sealing effect between the first shell 1 and the second shell 2 can be improved, and the negative pressure effect generated by the negative pressure suction massage component 6 on the sampling tube 5 can be further improved.

[0029] See Figure 13 In some embodiments, an annular mounting block can be fixed outside the first shell 1 and close to the second shell 2, and a connecting hose 8 can be used to fix it. A fixing seat 9 is provided at the other end of the connecting hose 8 to fix the entire device to other planes, thereby reducing the fatigue of the patient's arm caused by holding the device for a long time. The length and angle of the connecting hose 8 are adjustable, which can improve the flexibility of the device to a certain extent.

[0030] The second shell 2 is provided with an insulation component 7 for heating and keeping the sampling tube 5 warm. The insulation component 7 includes an insulation layer 701 sleeved on the outside of the sampling tube 5. The insulation layer 701 is a hollow cylindrical structure with a cross-sectional shape close to the "I" shape. A heating layer 702 is sleeved on the outside of the insulation layer 701. The heating layer 702 is a more common heating product, and its thickness can be just nested on the outside of the insulation layer 701. The heating layer 702 is sleeved on the outside of the insulation layer 703. The outside of the insulation layer 703 is in contact with the inside of the second shell 2. The walls are fixedly connected by means of snap-fitting or threaded connections. In addition, a controller 704 electrically connected to the heating layer 702 is provided on the outside of the second shell 2. The controller 704 is a common control panel structure, and a power supply capable of providing power input to the heating layer 703 is provided inside. By using the controller 704, the temperature and heating time of the heating layer 702 can be adjusted, and the temperature inside the sampling tube 5 can be adjusted to a range that can maintain sperm activity, thereby avoiding sperm inactivation, which in turn requires repeated sampling and places a burden on the sampler.

[0031] A method for using a sperm sampling device for reproductive medicine, comprising the following steps: S1. Fix the device to another plane through the connecting hose 8 and the fixing base 9. Then the sampler extends the body part along one end of the base 3 into the silicone ring 4 and slides the sliding ring 601 axially along the first shell 1; S2. When the sliding ring 601 slides, it can stretch or squeeze the airbag 602 and extract the air in the sampling tube 5 through the air inlet pipe 604, so that a negative pressure state is formed in the sampling tube 5. In combination with the massage ring 607, the sampler is massaged to improve the efficiency of sperm sampling; S3. After the semen is discharged into the sampling tube 5, the first shell 1 is separated from the second shell 2, and a sealing plug that can seal the sampling tube 5 is installed on the second shell 2. The internal temperature of the sampling tube 5 is adjusted by the controller 704 to maintain sperm activity. Before sampling, the controller 704 can also be used to preheat the inside of the sampling tube 5. Practical application cases

[0032] When the sampler needs to undergo a reproductive medicine examination, or when the sampler needs to take samples by himself in a place other than a hospital, he can first choose to fix the device to other planes through the fixing base 9 and adjust the position of the device through the connecting hose 8. In addition, the controller 704 can be used to preheat the sampling tube 5. The heat can be dissipated into the first shell 1 through the second shell 2, thereby providing a certain heating effect on the silicone ring 4, which is also conducive to improving the sampling efficiency. The sampler inserts a body part into the silicone ring 4 and manually slides the sliding ring 601 axially along the first shell 1. When the sliding ring 601 slides, a negative pressure state is gradually formed inside the sampling tube 5 through the action of the airbag 602 and the air inlet pipe 604. At the same time, the massage ring 607 on the sliding ring 601 can squeeze the silicone ring 4, providing a massage effect on the sampler's body part, thereby promoting the sampler's semen discharge; When semen is discharged into the sampling tube 5, the first shell 1 is separated from the second shell 2, and the sealing cover structure is screwed on the second shell 2 to seal the inside of the sampling tube 5. The temperature inside the sampling tube 5 is set by the controller 704 to ensure the activity of sperm inside the sampling tube 5 so that the sampler can be transported to the hospital for examination.
