Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figs. 1-3 This utility model provides a constant temperature sterilization blood storage rack. The blood storage rack includes a rack body 1, a temperature control box 2, an isolation cover 5, an ozone generator 7, an ozone concentration sensor 8, and a semiconductor cooling chip 9.

[0034] The frame 1 is placed on the top layer of the temperature control box 2. The frame 1 has multiple blood collection tube insertion holes 4 for placing blood collection tubes.

[0035] The inner wall of the temperature control box 2 is provided with semiconductor refrigerating sheets 9; the top of the temperature control box is provided with a plurality of limiting grooves 22 corresponding to the blood collection tube insertion hole 4;

[0036] The isolation cover 5 is arranged outside the blood storage rack, the top of the isolation cover 5 is provided with an ozone release port 6, the ozone release port 6 is connected with the ozone generator 7 through a transmission pipeline 10;

[0037] The ozone concentration sensor 8 is arranged inside the isolation cover 5, for monitoring the ozone concentration in real time and sending data to the ozone generator 7.

[0038] In an embodiment, the inner wall of the blood collection tube insertion hole 4 is provided with a flexible rubber ring, which can play a shock-absorbing role. In specific implementation, when the blood collection tube is inserted, the inner wall of the flexible rubber ring can tightly adhere to the outer wall of the blood collection tube, preventing the blood collection tube from moving during transportation, and also playing a certain sealing role to prevent ozone leakage.

[0039] In an embodiment, the front of the temperature control box 2 is provided with a pull-out baffle 21, and the semiconductor refrigerating sheets 9 are detachably arranged on the inner wall of the temperature control box 2. When the semiconductor refrigerating sheets 9 need to be replaced due to failure, the pull-out baffle 21 is only needed to be opened, and the semiconductor refrigerating sheets 9 in the box can be replaced.

[0040] In an embodiment, the inner wall of the limiting groove 22 is uniformly provided with cold air output holes 23; the limiting groove 22 is sleeved with a heat preservation tube, the inner diameter of the heat preservation tube is larger than the outer diameter of the blood collection tube, and the upper tube opening of the heat preservation tube is in contact with the lower outer ring of the blood collection tube insertion hole 4.

[0041] In use, the blood collection tube can be directly inserted into the heat preservation tube through the blood collection tube insertion hole 4, and the inner wall of the flexible rubber ring on the inner wall of the blood collection tube insertion hole 4 tightly adheres to the outer wall of the blood collection tube, preventing the blood collection tube from shaking. Since the heat preservation tube is sleeved on the top of the limiting groove 22, the cold air output from the cold air output holes 23 is directly input into the heat preservation tube, realizing concentrated cooling of the blood collection tube.

[0042] In an embodiment, the front of the isolation cover 5 is also provided with a transparent openable baffle 51. In specific implementation, the transparent openable baffle 51 can be opened to work inside the isolation cover. When work is not needed, the transparent openable baffle 51 is closed to isolate the external environment; at the same time, the transparent design can facilitate the observation of the staff on the situation inside the cover, such as the placement number and position of the blood collection tubes.

[0043] In an embodiment, the ozone generator 7 is provided with a timing device and an automatic closing function. In specific implementation, the ozone generator can be set to work for 10 minutes or 1 hour, and automatically closed when the time is up.

The inner wall of the temperature control box 2 is also provided with a temperature sensor for monitoring the temperature in the temperature control box 2 in real time and feeding back the data to the microcomputer control system.

[0045] In specific implementation, when the temperature sensor monitors the actual temperature in the temperature control box and feeds back the data to the microcomputer control system, the microcomputer control system controls the operation of the semiconductor refrigeration piece 9 according to the set temperature. For example, when the temperature in the box is higher than the set temperature, the microcomputer control system starts the semiconductor refrigeration piece 9; when the temperature in the box is equal to the set temperature, the microcomputer control system controls the semiconductor refrigeration piece 9 to maintain a constant working value.

[0046] In an embodiment, the blood storage rack further comprises a heat insulation enclosure 3 arranged at the top of the temperature control box 2 around the rack body 1. In specific implementation, the heat insulation enclosure 3 can integrally insulate the four sides of the rack body 1, and is convenient to take off when placing the blood collection tube and install again after placing. The thermal insulation cotton layer of the outer wall can effectively reduce heat conduction, so that the cooling effect is more durable.

[0047] In an embodiment, the heat insulation enclosure 3 is inserted at the top of the temperature control box 2.

[0048] The use process of the utility model is as follows:

[0049] In actual use, the collected blood sample is placed in the blood collection tube, then the blood collection tube is inserted through the blood collection tube insertion hole 4 of the rack body 1 into the heat preservation tube, and the inner wall of the flexible rubber ring is tightly attached to the outer wall of the blood collection tube. The microcomputer control system detects the real-time temperature value in the temperature control box 2, compares the real-time temperature value with the preset temperature in the microcomputer control system, starts the semiconductor refrigeration piece 9 to perform refrigeration or heating operation according to the temperature condition in the temperature control box 2, and keeps the temperature in the temperature control box 2 constant. The ozone generator 7 is started, the generated ozone gas enters the inside of the isolation cover 5 through the ozone release port 6, and the rack body 1 and the blood collection tube are sterilized and disinfected; the ozone concentration sensor 8 monitors the ozone concentration in real time and feeds back to the control system, so as to ensure that the ozone concentration is within a safe and effective range; the ozone generator is set to work for 1 hour, and is automatically turned off at the time; after sterilization is completed, the ozone is gradually decomposed into oxygen, and the whole process is safe and efficient without manual intervention.
