A storage slot 101 is opened inside the box body 100. Sliding members 102 are arranged on both sides of the inner wall of the storage slot 101. A fingerprint recognition module 103 is arranged on the front of the box body 100. A controller 104 and a battery 105 are arranged inside the box body 100. The fingerprint recognition module 103 is electrically connected to the controller 104, and the battery 105 can supply power to the fingerprint recognition module 103 and the controller 104; a storage component 400, the storage component 400 includes a storage rack 401, an electromagnet 402, and a baffle 403.

[0040] In this embodiment, the fingerprints of medical staff are pre - entered, and the medical staff are divided according to their specialties. Since the storage components 400 are pre - stratified for biological samples of different specialties, when the fingerprint is recognized, it can be known which specialty the medical staff belongs to. Subsequently, the battery 105 is made to stop supplying power to the electromagnet 402 of the storage component 400 of this specialty, and then the electromagnet 402 loses magnetism. After the electromagnet 402 loses magnetism, it will not stop attracting the magnetic plate 404. The medical staff can pull the baffle 403 to drive the storage rack 401 to change its position under the sliding action of the sliding member 102, thereby realizing the taking and placing of biological samples. At this time, the medical staff can take and place the biological samples of their specialty, thus avoiding the loss caused by medical staff of other specialties taking the biological samples of this specialty; each time the fingerprint is recognized, the fingerprint recognition time is recorded by the timer 107, and this information is stored in the memory 108.

[0041] Please refer to Figure 2 、 Figure 3, Figure 4 , Figure 5 , Figure 7 and Figure 9 , in some embodiments, the refrigeration assembly includes a cold liquid tank 200 and a cold liquid pump 201.

A cold air pipe 206 and a cold liquid solenoid valve 207 are arranged inside the box body 100. The cold liquid solenoid valve 207 is arranged on the surface of the cold air pipe 206. A cold air vent hole 405 is formed inside the storage rack 401. The cold air vent hole 405 and the cold air chamber 202 are connected through the cold air pipe 206. The cold liquid pump 201, the refrigeration sheet 203 and the cold liquid solenoid valve 207 are all electrically connected to the controller 104. The battery 105 is used to supply power to the cold liquid pump 201, the refrigeration sheet 203 and the cold liquid solenoid valve 207.

[0042] In this embodiment, when refrigerating, the cold liquid pump 201 is started, so that the liquid in the cold liquid tank 200 flows through the first cold liquid pipe 204 and the second cold liquid pipe 205 in sequence and then flows back to the cold liquid tank 200. The refrigeration sheet 203 effectively reduces the temperature of the liquid in the cold liquid tank 200, and then makes the liquid emit cold air when it is located in the second cold liquid pipe 205. The cold air will flow through the cold air pipe 206 and the cold air vent hole 405 in sequence to cool the biological samples placed in the storage rack 401. The second cold liquid pipe 205 is bent in the cold air chamber 202, increasing the liquid circulation time, and then effectively increasing the cold air emission duration. The flow of the cold liquid pipe can be controlled by the cold liquid solenoid valve 207 according to the actual situation to avoid the influence of external impurities on the second cold liquid pipe 205.

[0043] Please refer to Figure 3 , Figure 4 , Figure 5 , Figure 8 and Figure 9, in some embodiments, the heating component includes a hot liquid tank 300 and a hot liquid pump 301. A hot air cavity 302 is formed inside the box body 100. Both the hot liquid tank 300 and the hot liquid pump 301 are arranged inside the box body 100. A heating element 303 is provided on the surface of the hot liquid tank 300. The input end of the hot liquid pump 301 is connected to a first hot liquid pipe 304, and the other end of the first hot liquid pipe 304 extends into the hot liquid tank 300. The output end of the hot liquid pump 301 is connected to a second hot liquid pipe 305, and the other end of the second hot liquid pipe 305 passes through the hot air cavity 302 and extends into the hot liquid tank 300. A hot air pipe 306 and a hot liquid solenoid valve 307 are arranged inside the box body 100. A hot liquid ventilation hole 406 is formed inside the storage rack 401. The hot liquid ventilation hole 406 and the hot air cavity 302 are connected through the hot air pipe 306. The hot liquid solenoid valve 307 is arranged on the surface of the hot air pipe 306. The hot liquid pump 301, the heating element 303 and the hot liquid solenoid valve 307 are all electrically connected to the controller 104. The battery 105 is used to supply power to the hot liquid pump 301, the heating element 303 and the hot liquid solenoid valve 307.

[0044] In this embodiment, during heating, the hot liquid pump 301 pumps the liquid in the hot liquid tank 300 to flow through the first hot liquid pipe 304 and the second hot liquid pipe 305 in sequence and then flow back to the hot liquid tank 300. The heating element 303 raises the temperature of the liquid in the hot liquid tank 300, so that the liquid emits heat when it is located in the second hot liquid pipe 305. The hot air flows through the hot air pipe 306 and the hot liquid ventilation hole 406 in sequence to heat up the biological samples placed in the storage rack 401. The second hot liquid pipe 305 is bent inside the hot air cavity 302 to increase the liquid circulation time, thereby effectively increasing the hot air emission duration. The flow of the hot liquid pipe can be controlled by the hot liquid solenoid valve 307 according to the actual situation to prevent the influence of external impurities on the second hot liquid pipe 305.

[0045] Please refer to Figure 1 , Figure 2 , Figure 3 Figure 5 , Figure 6 and Figure 9, in some embodiments, a storage cavity 407 and a card slot 408 are formed inside the storage rack 401. An infrared ranging sensor 409 is disposed at the bottom of the card slot 408. The cold air duct 206 and the hot air duct 306 are both communicated with the storage cavity 407. The infrared ranging sensor 409 is disposed below the card slot 408 and is electrically connected to the controller 104. The battery 105 can supply power to the infrared ranging sensor 409. A display screen 106 is disposed on the front surface of the box body 100. A timer 107 and a memory 108 are disposed inside the box body 100. The timer 107, the memory 108 and the display screen 106 are electrically connected to the controller 104. The battery 105 can supply power to the timer 107, the memory 108 and the display screen 106. It further includes a terminal which includes a display and a wireless communicator. The display and the wireless communicator are electrically connected. The controller 104 and the wireless communicator are communicatively connected. A charging cable 109 is disposed on the back surface of the box body 100. The charging cable 109 is used to supply power to the battery 105.

[0046] In this embodiment, the biological sample is placed in the card slot 408. Since the number of card slots 408 is limited, when the biological sample is placed in the card slot 408, the infrared ranging sensor 409 will be blocked. Thus, it can be known that there is a biological sample placed in the card slot 408 at this position. The signal is transmitted to the controller 104, and finally the storage quantity and the available storage quantity of the biological samples in different storage components 400 are displayed through the display screen 106. The controller 104 can transmit the data monitored by the temperature sensor 410 and the infrared ranging sensor 409, the fingerprint recognition time of the fingerprint recognition module 103 and the affiliated medical staff to the wireless communicator, and then display them through the display, so as to achieve the effect of remote monitoring. The charging cable 109 charges the battery 105, and then the battery 105 supplies power to the corresponding structures.

[0047] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 and Figure 9, in some embodiments, a motor 500 is disposed inside the box body 100. The number of the motors 500 is multiple, and the multiple motors 500 are divided into two groups. The output end of one group of motors 500 extends into the cold air cavity 202 and is connected with a fan blade 501. The center of this group of fan blades 501 is on the same horizontal line as the center of the cold air duct 206. The output end of one group of motors 500 extends into the hot air cavity 302 and is connected with a fan blade 501. The center of this group of fan blades 501 is on the same horizontal line as the center of the hot air duct 306. The motor 500 is electrically connected to the controller 104, and the battery 105 can supply power to the motor 500. A temperature sensor 410 is disposed inside the box body 100. The number of the temperature sensors 410 matches the number of the storage components 400. The temperature sensors 410 respectively monitor the temperature of the storage components 400 and the interval restricted by the storage slots 101.

[0048] In this embodiment, the motor 500 can drive the fan blade 501 to rotate, improving the air circulation speed. One group of motors 500 driving the fan blade 501 to rotate can make the cool air emitted by the second cold-use pipe 205 flow into the cavity through the cold air duct 206, increasing the refrigeration effect. Similarly, one group of motors 500 driving the fan blade 501 to rotate can make the hot air emitted by the second hot-use pipe 305 flow into the cavity through the hot air duct 306, increasing the heating effect. By using different temperature sensors 410 to respectively monitor the temperatures inside different storage components 400, since different biological samples are suitable for different storage temperatures, when the temperature sensor 410 monitors that the temperature is lower than the set temperature threshold, heating is required at this time. At this time, by controlling the cold-use solenoid valve 207 to close the cold air duct 206, that is, to stop the refrigeration effect, and by controlling the hot-use solenoid valve 307 to open the hot air duct 306, at this time the hot air can flow through the hot air duct 306, thereby achieving the heating effect. Similarly, when the temperature sensor 410 monitors that the temperature is higher than the set threshold, cooling is required. At this time, by controlling the cold-use solenoid valve 207 to open the hot air duct 306, the cool air will flow through the cold air duct 206 to achieve the cooling effect, and by controlling the hot-use solenoid valve 307 to close the hot air duct 306, thereby stopping the heating. During this process, the temperature will be within the appropriate temperature range in a short time to meet the storage requirements of biological samples.

[0049] It should be noted that for the fingerprint recognition module 103, the controller 104, the battery 105, the electromagnet 402, the cold liquid pump 201, the refrigeration chip 203, the cold solenoid valve 207, the hot liquid pump 301, the heating element 303, the hot solenoid valve 307, the infrared ranging sensor 409, the motor 500, the temperature sensor 410, the display screen 106, the timer 107, the memory 108, the wireless communicator, and the display, the specific model specifications need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail; its power supply and principle are clear to those skilled in the art and will not be described in detail here; the connection and installation of each part and the signal transmission principle belong to the well-known technology in this field. Among them, the terminal can be a mobile phone, a tablet, a computer, etc., and the communication connection can be 4G, 5G, WIFI, local area network, Bluetooth, etc.

[0050] Specifically, the working principle of a storage device for biological samples provided in this application is as follows:

[0051] Fingerprints of medical staff are pre-entered in advance, and medical staff are classified according to their specialties. Since the storage components 400 are pre-layered with biological samples of different specialties, when the fingerprint is recognized, it can be known which specialty the medical staff belongs to. Subsequently, the battery 105 stops supplying power to the electromagnet 402 of the storage component 400 of this specialty, and the electromagnet 402 loses its magnetism. After the electromagnet 402 loses its magnetism, it will no longer attract the magnetic plate 404. The medical staff can pull the baffle 403 to drive the storage rack 401 to change its position under the sliding action of the sliding member 102, thereby realizing the taking and placing of biological samples. At this time, the medical staff can take and place the biological samples of their specialty, thus avoiding the loss caused by medical staff of other specialties taking the biological samples of this specialty;

[0052] Each time after fingerprint recognition, the timer 107 records the fingerprint recognition time and stores this information in the memory 108. Once a biological sample is lost, the information stored in the memory 108 is retrieved, and then the fingerprint recognition personnel can be screened within the set time, thereby reducing the difficulty of tracing the source;

[0053] Among them, the biological sample is placed in the card slot 408. Since the number of card slots 408 is limited, when the biological sample is placed in the card slot 408, it will block the infrared ranging sensor 409, and then it can be known that there is a biological sample placed in this card slot 408. This signal is transmitted to the controller 104, and finally the storage quantity and the available storage quantity of biological samples in different storage components 400 are displayed through the display screen 106;

[0054] When refrigerating, start the cooling liquid pump 201, so that the liquid in the cooling liquid tank 200 flows through the first cooling pipe 204 and the second cooling pipe 205 in sequence and then flows back to the cooling liquid tank 200. The cooling fin 203 effectively reduces the temperature of the liquid in the cooling liquid tank 200. Then, when the liquid is located in the second cooling pipe 205, it emits cool air. The cool air will flow through the cold air pipe 206 and the cooling ventilation hole 405 in sequence to cool the biological samples placed in the storage rack 401. A group of motors 500 drive the fan blades 501 to rotate, which can make the cool air emitted by the second cooling pipe 205 flow into the cavity through the cold air pipe 206, increasing the refrigeration effect;

[0055] When heating, start the heating liquid pump 301, so that the liquid in the heating liquid tank 300 flows through the first heating pipe 304 and the second heating pipe 305 in sequence and then flows back to the heating liquid tank 300. The heating element 303 raises the temperature of the liquid in the heating liquid tank 300. Then, when the liquid is located in the second heating pipe 305, it emits hot air. The hot air will flow through the hot air pipe 306 and the heating ventilation hole 406 in sequence to heat the biological samples placed in the storage rack 401. A group of motors 500 drive the fan blades 501 to rotate, which can make the hot air emitted by the second heating pipe 305 flow into the cavity through the hot air pipe 306, increasing the heating effect;

[0056] Use different temperature sensors 410 to monitor the temperatures in different storage components 400 respectively. Since the suitable storage temperatures of different biological samples are different, when the temperature sensor 410 monitors that the temperature is lower than the set temperature threshold, heating is required. Close the cold air pipe 206 by controlling the cooling solenoid valve 207, that is, stop the refrigeration effect. Control the heating solenoid valve 307 to make the hot air pipe 306 in circulation. At this time, the hot air can flow through the hot air pipe 306, thereby achieving the heating effect. Similarly, when the temperature sensor 410 monitors that the temperature is higher than the set threshold, cooling is required. At this time, control the cooling solenoid valve 207 to make the hot air pipe 306 in circulation, and the cool air will pass through the cold air pipe 206 to achieve the cooling effect. Control the heating solenoid valve 307 to close the hot air pipe 306, thereby stopping the heating. During this process, the temperature will be within the suitable temperature range for a short time to meet the storage of biological samples.
