Description

Technical Field

[0001] This utility model relates to the field of cryopreservation technology, and in particular to a sperm sealing cryopreservation tube. Background Technology

[0002] Sperm cryopreservation remains the only feasible method for preserving male fertility. Due to various treatment options and improved cure rates, the survival rate of cancer patients has increased significantly. However, cancer itself and its treatments, such as radiotherapy, chemotherapy, and certain surgical procedures, can be harmful to the gonads and may lead to testicular failure or ejaculatory dysfunction. Therefore, providing sperm cryopreservation for this group is crucial for their future fertility. At the same time, sperm cryopreservation can provide a clinical treatment option for patients with severe oligospermia and asthenospermia. Clinically, semen is collected through masturbation, a small amount is sampled for testing, and the remainder is stored in cryopreservation tubes with a preservative and finally placed in a liquid nitrogen tank for ultra-low temperature freezing.

[0003] Existing sperm cryopreservation tubes generally consist of a cap and a tube body connected by threads. This makes the threads prone to loosening, leading to sperm contamination by liquid nitrogen or air entering the tube, affecting the sperm preservation effect. Furthermore, the cap and tube body are connected by hand, which requires a certain amount of time to seal the injection port. When placing the cryopreservation tube after sperm collection, the lack of friction between the cryopreservation tube and the cryopreservation box means the cryopreservation tube may fall off due to tilting of the cryopreservation box. In addition, single cryopreservation tubes are often round at the bottom or long and thin, making them prone to tipping over during placement. Therefore, a sperm-sealing cryopreservation tube is needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the easy loosening of the threaded connection between the cap and the tube body, the inability to seal quickly, and the tendency to fall off or tilt and tip over. This invention proposes a cryopreservation tube for sealing sperm.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sperm cryopreservation tube includes a tube body, with fixing blocks symmetrically fixed to the inner side of the tube body. A cap is movably connected inside the tube body, and an inner sleeve is fixedly connected inside the cap. A pressing assembly is provided inside the inner sleeve, the pressing assembly including a pressing pestle and a button. A sealing sheet is movably connected inside the cap, and a movable plate is fixedly connected to the outside of the sealing sheet. A second spring is fixedly connected to the outside of the movable plate, with one end of the second spring away from the movable plate fixedly connected to the inner wall of the cap. A groove is formed on the inner wall of the tube body.

[0007] A third spring is symmetrically fixed to the outside of the tube. Each of the third springs, at the end furthest from the tube, is fixedly connected to a push plate. A sleeve is movably connected to the outside of the tube. By setting a pressing component, the sealing plate is pressed, causing it to slide on the inner sleeve and engage in the slot to seal the tube's injection port. This prevents the cap from falling off and causing liquid nitrogen contamination. It simplifies the process of hand-rotating the cap to seal the tube, quickly seals the tube's injection port, prevents excessive air from entering the tube, and ensures the preservation effect of sperm.

[0008] The above technical solution further includes:

[0009] The pressing pestle is movably connected to the outside of the inner sleeve. A first spring is fixedly connected to the inner wall of the inner sleeve. A limiting plate is fixedly connected to the outside of the pressing pestle. The first spring is movably connected to the limiting plate. A cam is fixedly connected to one end of the pressing pestle inside the inner sleeve.

[0010] The button is movably connected to the outside of the tube body, and a connecting tube is fixedly connected inside the inner sleeve. The button is movably connected inside the connecting tube, and the size of the button is adapted to the size of the opening of the connecting tube.

[0011] The connecting pipe has triangular grooves on its outer surface, and the number of these triangular grooves is in multiple groups and evenly distributed around the circumference. The connecting pipe also has elongated grooves on its outer surface, and the number of these elongated grooves is in multiple groups and evenly distributed around the circumference.

[0012] The sealing sheet is movably connected to the inside of the slot, and the size of the sealing sheet is adapted to the size of the slot opening. The movable plate is slidably connected to the cover.

[0013] The sleeve is movably connected to the outside of the tube body, and the sleeve is slidably connected to the push plate. The size of the push plate is adapted to the size of the sleeve opening.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, by setting a pressing component, the sealing sheet is pressed so that it slides on the inner sleeve and is locked into the slot to seal the tube injection port, preventing the cap from falling off and causing liquid nitrogen pollution. This simplifies the process of hand-rotating when sealing the cap and the tube, quickly sealing the tube injection port, preventing excessive air from entering the tube, and ensuring the sperm preservation effect.

[0016] 2. In this utility model, by setting a sleeve, the push plate is driven to open and tighten, and the squeezing force is applied to the inner side of the tube body and the cryopreservation box placement hole to prevent the tube body from falling off due to the tilt of the cryopreservation box. In addition, when placing a single tube body, opening the push plate increases the contact space of the base and increases the friction to prevent tilting and falling. Attached Figure Description

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] like Figure 1-6 As shown, the present invention proposes a sperm cryopreservation tube, comprising a tube body 1, a fixing block 2 symmetrically fixed to the inner side of the tube body 1, a cap 3 movably connected inside the tube body 1, an inner sleeve 4 fixedly connected inside the cap 3, a pressing assembly inside the inner sleeve 4, the pressing assembly including a pressing pestle 5 and a button 9, a sealing sheet 13 movably connected inside the cap 3, a moving plate 14 fixedly connected to the outside of the sealing sheet 13, a second spring 15 fixedly connected to the outside of the moving plate 14, one end of the second spring 15 away from the moving plate 14 fixedly connected to the inner wall of the cap 3, a slot 16 opened on the inner wall of the tube body 1, a third spring 17 symmetrically fixed to the outside of the tube body 1, a push plate 18 fixedly connected to the end of each third spring 17 away from the tube body 1, and a sleeve 19 movably connected to the outside of the tube body 1.

[0027] The pressing pestle 5 is movably connected to the outside of the inner sleeve 4. A first spring 6 is fixedly connected to the inner wall of the inner sleeve 4. A limiting plate 7 is fixedly connected to the outside of the pressing pestle 5. The first spring 6 is movably connected to the limiting plate 7. A cam 8 is fixedly connected to one end of the pressing pestle 5 inside the inner sleeve 4. A button 9 is movably connected to the outside of the tube body 1. A connecting tube 10 is fixedly connected to the inside of the inner sleeve 4. The button 9 is movably connected inside the connecting tube 10. The size of the button 9 is adapted to the size of the opening of the connecting tube 10. A triangular groove 11 is provided on the outside of the connecting tube 10. There are multiple sets of triangular grooves 11 evenly distributed around the circumference. A long groove 12 is provided on the outside of the connecting tube 10. There are multiple sets of long grooves 12 evenly distributed around the circumference. A sealing sheet 13 is movably connected to the inside of the slot 16. The size of the sealing sheet 13 is adapted to the size of the opening of the slot 16. A moving plate 14 is slidably connected to the cover 3.

[0028] The working principle of a sperm cryopreservation tube based on Embodiment 1 is as follows: When button 9 is pressed, because the end edge of button 9 is serrated, the end of cam 8 also has a corresponding toothed protrusion. Button 9 moves down, causing cam 8 to move down and rotate slightly according to the serrated inclined surface. As button 9 is pressed, cam 8 causes pressing pestle 5 to move down. When cam 8 moves down to a certain extent, the toothed protrusion at the end of cam 8 enters the triangular groove 11 along the inclined surface of the triangular groove 11 opened on the connecting tube 10. At this time, pressing pestle 5 is in the inserted state, the first spring 6 is compressed, and pressing pestle 5 and the first spring 6 are limited by limiting plate 7. At this time, pressing pestle 5 pushes sealing plate 13 to slide on inner sleeve 4, and provides support through moving plate 14. Second spring 15 tightens, and sealing plate 13 is inserted into the groove to lock and seal the injection port of cryopreservation tube.

[0029] Pressing button 9 again moves cam 8 and rotates it slightly. At this time, the toothed protrusion at the end of cam 8 enters the long groove 12 along the inclined surface of the long groove 12 opened on the connecting tube 10. Thus, it is pushed by the first spring 6 to push the pressing pestle 5 back, canceling the seal of the cap 3 on the tube body 1. This sealing method prevents the cap 3 from falling off and causing liquid nitrogen pollution. It simplifies the process of using hand rotation when sealing the cap 3 and the tube body 1, and quickly seals the injection port of the tube body 1, preventing too much air from entering the tube and ensuring the sperm preservation effect.

[0030] Example 2

[0031] like Figure 6 As shown, based on Embodiment 1, the sleeve 19 is movably connected to the outside of the tube body 1, and the sleeve 19 is slidably connected to the push plate 18. The size of the push plate 18 is adapted to the size of the opening of the sleeve 19.

[0032] In this embodiment, the design is such that when the cryopreservation tube needs to be placed into the cryopreservation box, the sleeve 19 is moved downwards, and the inclined surface on the inner side of the sleeve 19 causes the push plate 18 to tighten. At this time, the third spring 17 is in a tightened state. When it is placed into the cryopreservation box, the sleeve 19 is moved upwards, and the clamping force of the sleeve 19 on the push plate 18 is released. The push plate 18 is opened by the rebound force of the third spring 17, and the squeezing force is applied to the cryopreservation tube and the inner side of the cryopreservation box placement hole to prevent the tube 1 from falling off due to the tilt of the cryopreservation box. In addition, when placing a single tube 1, the push plate 18 is opened, which increases the contact space of the base and increases the friction to prevent tilting and falling.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
