Technical Field

[0001] The utility model belongs to the technical field of blood collection, in particular to a blood collection and cooling test tube rack. Background Art

[0002] Platelet-rich fibrin (PRF) is a platelet-rich biomaterial that is different from traditional platelet-rich plasma (PRP) technology. PRF can promote bone formation, especially improve the healing rate of bone transplant wounds. When PRF is used in tooth repair, the patient's blood is collected and cooled and centrifuged to obtain S-PRF serum and A-PRF jelly. The S-PRF serum, bone powder and part of the A-PRF jelly are mixed to prepare viscous bone, and the remaining part of the A-PRF jelly is flattened to prepare a solid plasma matrix membrane. The viscous bone and the solid plasma matrix membrane are used in combination for tooth repair. At present, when collecting blood from patients, the blood is collected into a test tube and then placed in a 4°C refrigerator for refrigeration. The purpose of cooling the blood immediately cannot be achieved. The current blood collection test tube rack is cooled by cooling water, or placed in a 4°C refrigeration device for cooling using an integral design structure.

[0014] Figure 3 It is a top view of the utility model. DETAILED DESCRIPTION

[0015] The utility model is described in detail below in conjunction with specific implementation methods:

[0016] like Figures 1 to 3 The blood collection and cooling test tube rack shown in the figure comprises a split test tube rack 1, an elastic annular belt 7 and a positioning pin 3. The split test tube rack 1 is provided with a buried hole on the inner side. Two split test tube racks 1 cooperate to form a test tube rack body. The split test tube racks 1 cooperate to form a test tube placement hole 2. One end of the positioning pin 3 is fixedly installed in the buried hole of one of the split test tube racks 1, and the other end of the positioning pin 3 is slidably installed in the buried hole of the other split test tube rack 1. The split test tube rack 1 is provided with a liquid injection port 12 with a sealing cover, and the elastic annular belt 7 is sleeved and installed on the two split test tube racks 1 of the split test tube rack 1 to fix the two.

[0017] A first notch 11 is provided on the outside of the split test tube rack 1, and the liquid injection port 12 is provided in the first notch 11. A limiting plate 13 is also fixedly provided in the first notch 11. A limiting bayonet is formed between the limiting plate 13 and the split test tube rack 1. The elastic annular band 7 is placed in the limiting bayonet. The liquid injection port 12 and the elastic annular band 7 are both located in the first notch 11. This can prevent the protruding liquid injection port 12 from getting stuck with the insulation bag when the test tube rack body is placed in the insulation bag, and can also reduce the size of the insulation bag. The limiting plate 13 can prevent the elastic annular band 7 from falling off and being lost from the split test tube rack 1 after the split test tube rack 1 is disassembled.

[0018] It also includes a tray 6, a second notch 14 is provided at the bottom of the split test tube rack 1, a raised limit strip 15 is provided at the bottom of the split test tube rack 1, the raised limit strip 15 is located in the second notch 14, and a limit slot matching the raised limit strip 15 is provided on the inner side of the vertical surface of the tray 6. The tray 6 is mounted on the raised limit strip 15 at the bottom of the two split test tube racks 1 through its limit slot. The tray 6 can limit the extreme position of the downward movement of the blood collection test tube to prevent the lower part of the blood collection test tube from exceeding the bottom of the test tube rack body and affecting the cooling effect.

[0019] The outer side of the split test tube rack 1 is fixedly covered with a plush cloth pad 5. The blood sampling personnel can pinch the plush cloth pad 5 on both sides of the low-temperature test tube rack body with their hands to improve the comfort of operation.

[0020] One end of the positioning pin 3 is screwed and fixed in a buried hole of one of the split test tube racks 1 . By rotating the positioning pin 3 , the gap between the two split test tube racks 1 can be adjusted to meet actual use requirements.

[0021] The left and right sides of the test tube rack body are provided with arc-shaped notches 4 that penetrate vertically, and the fingers of the blood collector are inserted into the arc-shaped notches 4 to facilitate the removal of the elastic annular band 7 from the test tube rack body.

[0022] The split test tube rack 1 is placed in a refrigeration device at 4°C for cooling. When in use, two split test tube racks 1 are taken to form a test tube rack body, and the two split test tube racks 1 are fixed by the elastic annular band 7. The blood collection test tube is placed in the test tube placement hole 2 in the test tube rack body, and the collected blood can be timely cooled by the low-temperature test tube rack body.
