Technical Field

[0001] The utility model relates to the technical field of sperm storage, and specifically, to a micro sperm freezing carrier rod. Background Art

[0002] Sperm freezing refers to the technology of storing sperm in an ultra-low temperature environment for a long time. Generally, it is stored in a liquid nitrogen tank at -196°C, which can temporarily make sperm out of the growth state and preserve sperm characteristics, and then resuscitate when needed. The micro freezing carriers for rare sperm mainly include empty zona pellucida, freezing loops, carrier-free droplets, freezing films, etc.

[0003] The utility model patent publication number CN205922672U discloses a closed freezing carrier rod device for freezing seminiferous tubules or sperm, including a carrier rod body and a carrier rod sleeve. The carrier rod body includes a handheld part and a connecting part, and the connecting part and the handheld part are integrally formed. The end of the connecting part is connected to a freezing groove through a flat connecting rod. The structure of the freezing groove is a circular groove, which is relatively small, and the loading capacity is increased by increasing the depth of the groove.

[0036] Example 1

[0037] As Figure 1 shown, a micro sperm freezing carrier rod includes a carrier rod body 1 and a carrier rod sleeve 2. The carrier rod body 1 includes a handheld part 11 and a connecting part 12. The handheld part 11 facilitates the operator to hold and operate the carrier rod body 1, ensuring stability during the sampling, storage, and transfer of sperm freezing liquid. The side of the connecting part 12 is used for pasting a label, and the information of the label includes the information of the sperm freezing liquid stored in the freezing part 13, such as: the identification number of the sperm sample or the patient's name, the collection date and time, the storage conditions, etc.

[0038] The handheld part 11 and the connecting part 12 are integrally formed, reducing the assembly steps of the carrier rod body 1, simplifying the production process, and improving the processing and production efficiency of the carrier rod body 1; the integrally formed structure has no seams or connection points, making the carrier rod body 1 more durable. The connecting part 12 is used to connect the handheld part 11 and the freezing part 13. Specifically, the end of the connecting part 12 is provided with the freezing part 13. The freezing part 13 is semi-cylindrical, having a strip-shaped long groove for storing sperm freezing liquid. The sperm freezing liquid storage capacity of the freezing part 13 is 20 microliters. It can be seen that in this solution, by designing the freezing part 13 as semi-cylindrical with a strip-shaped long groove, the sperm freezing liquid can be stored throughout the entire long groove, increasing the sperm freezing liquid storage capacity.

[0039] In this embodiment, the cross-section of the freezing part 13 is a semi-circular arc, and the radius of the semi-circular arc is 1 millimeter, increasing the structural stability of the freezing part 13 and reducing the risk of deformation during storage and operation.

[0040] The length of the freezing part 13 is 5 millimeters less than the length of the connecting part 12. Specifically, the length of the freezing part 13 is equal to 25 millimeters, and the length of the connecting part 12 is equal to 30 millimeters. The freezing part 13 has a certain length. Compared with the traditional small circular groove, the semi-cylindrical freezing part 13 can provide more space to store sperm freezing liquid.

[0041] The length of the handheld part 11 is not less than the length of the connecting part 12, and the shape of the handheld part is a multi-prism. Preferably, the cross-section of the handheld part is a rectangle, facilitating the operator to hold the handheld part 11 more stably during operation. Preferably, the length of the connecting part 12 is equal to 30 millimeters, and the length of the handheld part 11 is equal to 35 millimeters. The handheld part 11 and the connecting part 12 with comparable lengths help to maintain the balance of the entire carrier rod body 1, making the operator more stable during operation and reducing hand fatigue caused by uneven weight distribution.

[0042] As Figure 3As shown, the length of the carrier rod sleeve 2 is greater than the sum of the lengths of the connecting portion 12 and the freezing portion 13. In this embodiment, the length of the connecting portion 12 is equal to 30 millimeters, the length of the freezing portion 13 is equal to 25 millimeters, and the length of the carrier rod sleeve 2 is equal to 75 millimeters. Since 75 > 30 + 25, that is, the length of the carrier rod sleeve 2 is much greater than the sum of the lengths of the connecting portion 12 and the freezing portion 13, it can be avoided that after the carrier rod sleeve 2 is sleeved on the carrier rod body 1, the freezing portion 13 touches the closed-end of the carrier rod sleeve 2, resulting in damage to the freezing portion 13 and the sperm freezing liquid stored therein.

[0043] As Figure 2 shown, in order to ensure that the freezing portion 13 is not easily damaged when the carrier rod sleeve 2 is installed, the distance from the end of the freezing portion 13 to the closed-end of the carrier rod sleeve 2 is at least 15 millimeters. A marking area 131 is provided at the end of the freezing portion 13. The marking area 131 can be marked in black. When the carrier rod sleeve 2 is sleeved on the carrier rod body 1, since the carrier rod sleeve 2 is made of a transparent material, the operator can use the marking area 131 to know the position of the end of the freezing portion 13.

[0044] An annular boss 14 is provided between the hand-held portion 11 and the connecting portion 12. When the carrier rod sleeve 2 is sleeved on the connecting portion 12, the end of the carrier rod sleeve 2 abuts against the annular boss 14. The operator can quickly and accurately sleeve the carrier rod sleeve 2 on the connecting portion 12. The annular boss 14 serves as a physical stop to ensure that the carrier rod sleeve 2 will not be over-sleeved and damage the freezing portion 13 and the sperm freezing liquid stored therein. Due to the presence of the annular boss 14, the operator can quickly judge whether the carrier rod sleeve 2 has been correctly sleeved, reducing the time for repeated adjustment and improving the operation efficiency.

[0045] In this embodiment, one end of the carrier rod sleeve 2 forms a closed structure through a metal block 21, and the other end is an open end. The carrier rod sleeve 2 is sleeved on the carrier rod body 1 through the open end.
