Description

Technical Field

[0001] The invention relates to the technical field of sperm transportation and preservation, and in particular to a sperm transportation and preservation device. Background Art

[0002] Sperm is a special protein with the ability to fertilize. Sperm needs to be refrigerated or frozen during transportation to maintain its vitality and quality. Normally, sperm can be refrigerated in an environment of 4-8°C for short-distance transportation. For long-distance transportation or long-term storage, sperm usually uses liquid nitrogen freezing technology. For example, a sperm freezing device with publication number CN110367245A uses liquid nitrogen to freeze sperm; a sperm collection and storage device with publication number CN211810973U uses cold air emitted by ice in combination with a temperature controller to put sperm in the test tube into hibernation more quickly.

[0003] In the current prior art, multiple sperm storage tubes of multiple people are usually placed in the same storage box. When taking or searching for some storage tubes, the box door needs to be opened for operation. However, opening the box door will accelerate the loss of cold air in the box, which will greatly affect the temperature in the box. If the storage box is cooled by refrigeration materials, the loss of cold air will easily lead to a decrease in the refrigeration effect, which will easily shorten the sperm storage time. If the storage box is cooled by electronic equipment such as a refrigerator, the refrigerator needs to be started if the cold air loss is large, which will easily increase energy consumption.

[0044] The outer box 1, the top door 7 and the box door 3 are all sealed, and the outer box 1 is made of heat-insulating material, and the inner box 2 is made of heat-conducting material. The refrigeration chamber is used to store refrigeration materials for refrigerating and preserving sperm. After putting refrigeration materials such as ice cubes or refrigerants into the refrigeration chamber, the top door 7 is closed, and the temperature of the refrigeration material is transmitted to the inner box 2 through the inner box 2 for refrigeration and preservation of the sperm storage tube in the inner box 2 during transportation.

[0045] A liquid nitrogen inlet pipe connected to the inside of the inner box 2 can also be fixed on one side of the outer box 1. During long-distance transportation, the liquid nitrogen inlet pipe is connected to a liquid nitrogen generator. A liquid nitrogen generator is a device that uses gas separation technology to produce liquid nitrogen. It usually includes components such as an air storage tank system, a nitrogen buffer system, a nitrogen-oxygen separation system, and an electrical control system. The working principle of the liquid nitrogen generator is to generate high-purity nitrogen through pressure swing adsorption (PSA) or other gas separation technologies, and then liquefy the nitrogen through a cooling process, and finally store or transport it as liquid nitrogen. The liquid nitrogen generator injects liquid nitrogen into the inner box 2 through the liquid nitrogen inlet pipe to achieve sperm cryopreservation, or:

[0046] A small liquid nitrogen generator is installed on the outer box 1, and the liquid nitrogen generator is always connected to the liquid nitrogen inlet pipe. A temperature control system and a power supply are installed on the outer box 1. The temperature control system is a temperature management system that realizes temperature energy saving and enhanced management through computer programmed control. The temperature control system can display the temperature in the inner box 2 in real time. When the temperature is lower than the set freezing temperature, the liquid nitrogen generator injects liquid nitrogen into the inner box 2 through the liquid nitrogen inlet pipe to maintain the sperm freezing temperature. The installation and specific working principle of the temperature control system, power supply and liquid nitrogen generator all use existing technologies and will not be further elaborated here.

[0047] like Figure 1-4 , Figure 6-11 As shown, a plurality of groups of storage components 4 distributed up and down are provided inside the inner box 2, and each group of storage components 4 includes a storage tray 41, and a plurality of placement grooves 42 and slide grooves 43 distributed in a rectangular array are provided on the top of the storage tray 41, and the slide groove 43 is provided between two adjacent placement grooves 42 on the left and right.

[0048] Next, a fixing mechanism 44 for fixing the sperm storage tube is provided in the placement groove 42, and each set of fixing mechanisms 44 includes two clamping blocks 441 distributed front and back in the placement groove 42, a bottom pad 48 is provided at the bottom of the clamping blocks 441, and a sliding rod 442 is fixed on the opposite sides of the two clamping blocks 441, and a spring 443 is sleeved on the outer side of the sliding rod 442. Each clamping block 441 is provided with a mounting groove 46 at both ends, and the sliding rod 442 extends into the mounting groove 46 and is slidably connected with the mounting groove 46. The spring 443 is arranged in the installation groove 46, and the two ends of the spring 443 are fixedly connected to the inner walls of the front and rear sides of the installation groove 46 respectively; the sperm storage tube is clamped in the placement groove 42 by the clamp block 441 under the elastic force of the spring 443. In practice, the side of the clamp block 441 that contacts the sperm storage tube can be processed into an arc surface that fits the outer wall of the tube more closely. At the same time, a rubber pad is fixed on the side of the clamp block 441 that contacts the sperm storage tube to improve the clamping force on the sperm storage tube and improve the stability of the sperm storage tube.

[0049] A driving assembly 5 is provided inside the inner box 2. The driving assembly 5 is provided on one side of the storage assembly 4 and is used to drive the storage tray 41 to extend out or enter the preservation box to facilitate the taking and placing of the sperm storage tubes. Specifically, the driving assembly 5 includes an outer shell 51 fixed to one side of the inner box 2. The outer shell 51 is provided with the same number of driving parts as the storage assemblies 4, and each group of driving parts is respectively provided on one side of each group of storage assemblies 4. The outer shell 51 is provided with the same number of sliding grooves 55 as the storage assemblies 4 on one side close to the storage assemblies 4.

[0050] The driving part includes a screw rod 52 rotatably connected to the inside of the shell 51, the front end of the screw rod 52 extends out of the front end of the shell 51 and is fixed with a knob 56, a screw nut 53 is threadedly connected to the screw rod 52, a slider 54 is fixed to the side of the screw nut 53 close to the storage tray 41, the side of the slider 54 away from the screw nut 53 passes through a sliding groove 55 and is fixedly connected to the storage tray 41, and the slider 54 can slide back and forth along the sliding groove 55, and the side of the storage tray 41 away from the slider 54 is slidably connected to the other side wall inside the inner box 2 through a slide rail.

[0051] The box door 3 is provided with an opening 2 32 and a plurality of openings 1 31 penetrating through the box door 3, and the number of the openings 1 31 is the same as the number of the storage components 4. When the box door 3 cover is arranged at the front end of the preservation box, the front end of the storage tray 41 is stuck in the opening 1 31, and the storage tray 41 and the opening 1 31 are sealed. The front end of the shell 51 is stuck in the opening 2 32, and the shell 51 and the opening 2 32 are sealed. The knob 56 is arranged outside the preservation box. In order to prevent the knob 56 from being accidentally touched and rotated during transportation, a protective cover covering the outside of the knob 56 can be hingedly installed at the front end of the shell 51, or bolts or other structures for fixing the knob 56 can be installed on the shell 51, and the bolts can be loosened when the knob 56 needs to be rotated.

[0052] Next, an opening and closing mechanism 45 is provided in the slide 43 for driving the two clamping blocks 441 to open and close, and is used to drive the clamping blocks 441 to open synchronously when the storage assembly 4 extends out of the outer box 1, so as to facilitate the taking and placing of the sperm storage tube clamped by the clamping blocks 441; each set of opening and closing mechanisms 45 includes two slide plates 451 distributed front and back in the slide 43, an air bag 452 is fixedly attached between the two slide plates 451, and the two sides of each slide plate 451 are respectively fixed to the two clamping blocks 441 adjacent to the left and right thereof, and the bottom of each air bag 452 is fixedly connected to a branch pipe 453; the bottom of each row of slides 43 is connected to a through groove 47, and the through groove 47 is opened at the bottom of the storage tray 41, and multiple branch pipes 453 pass through the through groove 47 and are collected and connected to a main pipe 454, and the main pipe 454 is fixed to one side of the bottom of the storage tray 41, and a gas conveying member is provided on one side of the main pipe 454;

[0053] The gas conveying member includes an outer tube 455 and a piston rod 456, wherein the piston rod 456 is arranged inside the outer tube 455 and extends out of the rear end of the outer tube 455, the outer tube 455 is fixed to the side of the housing 51 close to the storage assembly 4, the top of the end of the piston rod 456 away from the outer tube 455 is fixed to the bottom end of the storage tray 41, so that the piston rod 456 can move with the storage tray 41, and the outer tube 455 is connected to the main pipe 454 through the connecting pipe 457. In order to facilitate the movement of the storage tray 41, the branch pipe 453, the main pipe 454, and the connecting pipe 457 are preferably selected from pipe fittings such as bellows that can be arbitrarily extended and bent.

[0054] When taking the sperm storage tubes in each layer of the storage component 4, it is not necessary to open the box door 3. Only need to rotate the knob 56 on one side of the storage component 4. The rotation of the knob 56 drives the rotation of the lead screw 52, so that the lead screw nut 53 and the slider 54 on the lead screw 52 move forward, thereby driving the storage tray 41 of the storage component 4 to extend forward through the first opening 31 outside the storage box. When the storage tray 41 moves forward, the piston rod 456 at its bottom also moves forward, so as to push the air in the outer cylinder 455 into the airbag 452 through the connecting pipe 457, the main pipe 454 and the branch pipe 453, causing all the airbags 452 in the storage tray 41 to expand. The expansion of the airbag 452 drives the two sliding plates 451 outside the airbag 452 to open along the sliding groove 43, thereby driving the clamping block 441 to open. In this way, when the storage tray 41 extends outside the storage box, the clamping block 441 opens synchronously. At this time, it is convenient for personnel to take and place the sperm storage tubes in the storage tray 41. After the operation is completed, the personnel reverse the knob 56 to reset the above structure. When the storage tray 41 returns to the storage box, the clamping block 441 closes synchronously, so that the clamping block 441 fixes the sperm storage tube in the placement groove 42 under the elastic force of the spring 443, improving the stability of the sperm storage tube during transportation; at the same time, since it is not necessary to open the box door 3 when taking the sperm storage tubes in each layer of the storage component 4, the loss of cold air in the storage box is effectively reduced.

[0055] In order to further reduce the loss of cold air in the storage box when the storage tray 41 extends outside the storage box, as Figure 1 、 Figure 2 、 Fig.12 and Fig.13 shown, a suction component 6 with the same number as the first opening 31 is fixed at the rear end of the box door 3, and each suction component 6 is respectively arranged outside each first opening 31. The suction component 6 includes a U-shaped pipe 61 fixed at the rear end of the box door 3. The U-shaped pipe 61 is arranged outside the first opening 31. An air hole 62 communicating with the inner cavity of the U-shaped pipe 61 is opened on the inner side of the U-shaped pipe 61. An outer cover 63 is arranged on the side of the U-shaped pipe 61 far away from the second opening 32. The outer cover 63 is fixed on the rear side of the box door 3, and each outer cover 63 is respectively arranged at the bottom of the upper slide rail of each storage tray 41;

[0056] A micro fan 64 is fixed in the outer cover 63. The space behind the micro fan 64 in the outer cover 63 is the air intake cavity. The U-shaped pipe 61 is communicated with the air intake cavity through a connecting pipe 65. The space in front of the micro fan 64 in the outer cover 63 is the air outlet cavity. A plurality of through openings communicating with the air outlet cavity are opened on both sides of the outer cover 63;

[0057] A touch switch 8 is provided at the rear end of each storage tray 41, and the touch switch 8 is fixedly embedded in the inner wall of the inner box 2. The micro fans 64, the touch switch 8 on the front and rear sides of one storage tray 41 are connected in series with a battery in the same circuit. The battery can be installed at a suitable position on the outer box 1 as required. The touch switch 8 is a normally closed touch switch, which is in a closed state when not triggered, that is, the current can flow freely. When the switch is triggered, the switch will disconnect and prevent the current from flowing. That is, when the storage tray 41 presses the touch switch 8, the micro fan 64 is turned off, and when the storage tray 41 leaves the touch switch 8, the micro fan 64 is turned on.

[0058] When the storage tray 41 extends out of the storage box, the storage tray 41 does not press the touch switch 8, so that the micro fan 64 at the position of the storage tray 41 is turned on. The cold air around the opening 31 at the position of the storage tray 41 enters the outer cover 63 through the air holes 62, the U-shaped pipe 61, and the connecting pipe 65, so that a slight negative pressure is generated at the opening 31, effectively preventing the cold air in the storage box from escaping through the opening 31. The cold air absorbed by the micro fan 64 is then discharged into the storage box through the through port for circulation.

[0059] In addition, when the box door 3 is opened for maintenance or cleaning inside the storage box, in order to avoid the micro fan 64 working at this time, a main switch is connected in series in the series circuit of the micro fan 64, the touch switch 8, and the battery. Closing the main switch can make the micro fan 64 not work.
