Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a freezing and storing device for a sperm sample freezing carrier. Background Art

[0002] At present, the freezing carriers for sperm samples mainly include freezing rings, freezing tubes and freezing rods. After the sperm samples are stored in the freezing carriers and then frozen, the freezing carriers need to be immersed in liquid nitrogen for freezing preservation. Since the temperature of liquid nitrogen is relatively low (-196°C), and the temperature inside the freezing carrier is quite different from that of liquid nitrogen. If the freezing carrier is directly immersed in liquid nitrogen, due to the large temperature difference, it will have an impact on the sperm samples stored in the freezing carrier. Therefore, it is necessary to cool the freezing carrier to a temperature not much different from that of liquid nitrogen before immersing the freezing carrier in liquid nitrogen. At present, the existing method for cooling the sperm samples is mainly to fix the freezing carrier on a connecting rod, and then place the connecting rod on a freezing box filled with liquid nitrogen, so that the freezing carrier is at a certain height from the liquid level of liquid nitrogen, and the freezing carrier is cooled by the temperature above the liquid level of liquid nitrogen. After the temperature of the freezing carrier drops to a temperature not much different from that of liquid nitrogen, the freezing carrier is then immersed in liquid nitrogen. However, this cooling method cannot ensure the stepped cooling of the freezing carrier, resulting in a poor cooling effect on the sperm samples in the freezing carrier. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a freezing and storing device for a sperm sample freezing carrier, which can cool the freezing carrier step by step and thus has a better cooling effect on the sperm samples in the freezing carrier.

[0004] The purpose of the utility model is achieved by adopting the following technical scheme:

[0005] A freezing and storing device for a sperm sample freezing carrier includes a fixing frame, a connecting handle and a freezing platform. The fixing frame is used to be fixed on a freezing box for loading liquid nitrogen. The connecting handle is adjustably arranged on the fixing frame so that the connecting handle can move up and down along the height direction of the fixing frame. An installation part for installing a freezing carrier storing sperm samples is arranged on the freezing platform. The freezing platform is fixed on the connecting handle. An adjustment groove penetrating through the opposite surfaces of the fixing frame is formed on the fixing frame. The adjustment groove is arranged along the height direction of the fixing frame. A threaded hole penetrating through the opposite surfaces of the connecting handle and corresponding to the adjustment groove is arranged on the connecting handle. The fixing frame and the connecting handle are fixed on the fixing frame by a first fastener passing through the adjustment groove and the threaded hole in sequence and being threadedly connected and locked with the first fastener by a second fastener.

[0006] Furthermore, a dimension scale line is arranged on one side edge of the adjustment groove on the fixing frame.

[0007] Further, a hook is fixedly arranged at the top of the fixing frame.

[0008] Further, a clamping part for clamping and fixing on the inner wall of the freezing box is fixedly arranged on the fixing frame.

[0009] Further, a plurality of sample slots are arranged at intervals on the freezing platform to form the installation part.

[0010] Further, the sample slots are arranged on the surface of the freezing platform facing away from the liquid nitrogen.

[0011] Further, the freezing platform is detachably connected to the connecting handle.

[0012] Further, the freezing platform is fixedly arranged on the connecting handle.

[0013] Further, the freezing platform and the connecting handle are connected by welding.

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

[0023] Embodiment:

[0024] Please refer to Figures 1-3 , the present utility model shows a freezing storage device for a sperm sample freezing carrier, including a fixing frame 10, a connecting handle 20, and a freezing platform 30. The fixing frame 10 is used to be fixed on a freezing box for loading liquid nitrogen. The connecting handle 20 is adjustably arranged on the fixing frame 10 so that the connecting handle 20 can move up and down along the height direction of the fixing frame 10. An installation part for installing a freezing carrier storing a sperm sample is arranged on the freezing platform 30. The freezing platform 30 is fixed to the connecting handle 20. An adjustment groove 101 penetrating through its opposite surfaces is formed on the fixing frame 10. The adjustment groove 101 is arranged along the height direction of the fixing frame 10. A threaded hole 201 penetrating through its opposite surfaces and corresponding to the adjustment groove 101 is provided on the connecting handle 20. The fixing frame 10 and the connecting handle 20 are fixed to each other by a first fastener 40 (screw) passing through the adjustment groove 101 and the threaded hole 201 in sequence and being threadedly connected and locked with the first fastener 40 (screw) by a second fastener 41 (nut).

[0025] When the utility model is in use, the fixing frame 10 is fixed on the freezing box, and the height of the freezing platform 30 from the liquid level of liquid nitrogen in the freezing box is adjusted by adjusting the lifting height of the connecting handle 20. Since the freezing carrier storing the sperm sample is installed on the installation part of the freezing platform 30, the stepped cooling effect of the freezing carrier is realized, and thus the cooling effect of the sperm sample stored in the freezing carrier is better. The closer the freezing platform 30 is to the liquid level of liquid nitrogen, the lower its temperature is.

[0026] It should be noted that the groove surface of the adjustment groove 101, the outer surface of the fixing frame 10, and the outer surface of the connecting handle 20 are not smooth surfaces. The stability of the connection between the fixing frame 10 and the connecting handle 20 is ensured by the friction force during contact. During use, the contact between the fixing frame 10 and the connecting handle 20 can be reduced by screwing the second fastener 41, and then the position of the first fastener 40 in the adjustment groove 101 is adjusted to realize the adjustment of the height of the connecting handle 20.

[0027] Certainly, in other embodiments, the structure in which the connecting handle 20 is adjustably arranged on the fixing frame 10 can also be realized by the following structure: for example, a plurality of threaded holes are arranged at intervals on the fixing frame 10, and the size of the holes on the fixing frame 10 is the same as that of the threaded hole 201. In this way, the height adjustment of the connecting handle 20 is realized by the cooperation of the threaded hole 201 and the holes at different positions on the fixing frame 10. In addition, a plurality of clamping positions can be arranged at intervals on the fixing frame 10, and each clamping position is arranged along the height direction of the fixing frame 10. A plurality of buckle structures corresponding to each clamping position are arranged on the connecting handle 20, and each clamping position is adapted to each buckle structure. In this way, the connecting handle 20 and the fixing frame 10 can be connected through the cooperation of the buckle structure and the clamping position. Therefore, the structure in which the connecting handle 20 is arranged on the fixing frame 10 is not limited here. For those skilled in the art, by reasonably changing the structure in which the connecting handle 20 is arranged on the fixing frame 10, it should also fall within the protection scope of the present utility model.

[0028] In this embodiment, a size scale line is arranged on one side edge of the adjustment groove 101 on the fixing frame 10. Since the adjustment height of the freezing platform 30 depends on the groove length of the adjustment groove 101, by arranging the size scale line on one side edge of the adjustment groove 101, it is convenient to know the adjustment height of the freezing platform 30 in real time, and thus the height of the freezing carrier from the liquid nitrogen liquid level in the freezing box can be known in real time. Of course, the length of the adjustment groove 101 is designed by the inventor according to the height that the freezing platform 30 needs to be adjusted, and it is not limited here.

[0029] In this embodiment, a hook 103 is fixedly arranged on the top of the fixing frame 10. That is, when the cryopreservation device of the present utility model is in an idle state, the connecting handle 20 is removed from the fixing frame 10 to avoid occupying space during storage, and the hook 103 facilitates the hanging storage of the fixing frame 10; when the cryopreservation device of the present utility model completes the stepwise cooling process, the cryopreservation device can be taken out of the freezing box by lifting the hook 103, and then the sperm sample is transferred to a sealed freezing tank for storing the sperm sample to achieve the cryopreservation of the sperm sample. It should be noted that during the stepwise cooling process of the cryopreservation device, it is not necessary to ensure that the freezing box is completely closed, as long as the stepwise cooling effect is achieved.

[0030] In this embodiment, a clamping portion 102 for clamping and fixing on the inner wall of the freezing box is fixedly arranged on the fixing frame 10. That is, when the sperm sample freezing carrier cryopreservation device of the present utility model is in use, the cryopreservation device of the present utility model is clamped and fixed on the inner wall of the freezing box through the clamping portion 102, which plays a role in fixing the position of the cryopreservation device of the present utility model and facilitates the stepwise cooling process of the cryopreservation device of the present utility model. After the stepwise cooling of the sperm sample is completed, the cryopreservation device is taken out of the freezing box by lifting the hook 103, and then the sperm sample is transferred to a sealed freezing tank for storing the sperm sample to achieve the cryopreservation of the sperm sample.

[0031] In this embodiment, a plurality of sample slots 301 are arranged at intervals on the freezing platform 30 to form the above-mentioned installation portion. Among them, the cryopreservation carrier in this embodiment is a cryopreservation tube, and arranging a plurality of sample slots 301 can place a plurality of cryopreservation tubes, that is, one sample slot 301 places one cryopreservation tube. Further, the sample slots 301 are arranged on the surface of the freezing platform 30 facing away from the liquid level of liquid nitrogen. In this way, through these sample slots 301, it is convenient to install and place the cryopreservation tubes, and at the same time, the installation situation of the cryopreservation tubes can be observed.

[0032] Of course, in other embodiments, if the cryopreservation carrier is a freezing ring, then the structure of the installation portion also changes with the structure of the cryopreservation carrier. That is, the inventor can reasonably change the structure of the installation portion according to the actual situation, and it is not limited to the structure shown in the following drawings.

[0033] In this embodiment, the freezing platform 30 is detachably connected to the connecting handle 20, so that it is convenient to disassemble and assemble the freezing platform 30 and the connecting handle 20.

[0034] Of course, in other embodiments, the freezing platform 30 can also be fixedly arranged on the connecting handle 20, that is, the freezing platform 30 and the connecting handle 20 are connected by welding, and no limitation is made here.

[0035] The above embodiments are only the preferred embodiments of the present utility model, and the scope of protection of the present utility model cannot be limited thereby. Any non-substantial changes and substitutions made by those skilled in the art based on the present utility model fall within the scope of protection required by the present utility model.
