Description

Technical Field

[0001] This utility model relates to the field of temperature detection equipment, and in particular to a passive medical refrigerator temperature calibration and testing instrument. Background Technology

[0002] A passive medical refrigerator uses highly efficient insulating materials for its body and stores a certain amount of refrigerant inside. In a sealed state, it can effectively maintain a low internal temperature for an extended period. A passive medical refrigerator with a built-in temperature display consists of three parts: the insulated body, the refrigerant, and a digital thermometer. Its internal volume is typically no more than 60L, and the operating ambient temperature should not exceed 55℃. Refrigerators are commonly used to store and transport items such as medicines, reagents, samples, blood, and biological products that require low-temperature storage and transportation.

[0003] Currently, there is a lack of a dedicated instrument for calibrating and testing the temperature of passive medical refrigerators. As a result, testing personnel often use constant temperature test chambers with operating ports to calibrate and test these refrigerators, which is cumbersome and costly. Therefore, providing a simple, low-cost instrument for calibrating and testing the temperature of passive medical refrigerators has become a pressing problem for those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to provide a passive medical refrigerator temperature calibration and testing instrument to solve the problems of cumbersome operation and high cost of existing refrigerator testing equipment.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

The inner box is installed inside the outer box, and clean water is stored in the gap between the outer box and the inner box. An electric heater for heating the clean water is installed at the bottom of the outer box. A digital thermometer is installed on the inner wall of the inner box, and a lid is installed on the top of the inner box. The passive medical refrigerator is placed inside the inner box. The main controller is electrically connected to the digital thermometer and the electric heater, respectively, and the main power supply supplies power to the electric heater.

[0009] Optionally, the temperature detection device includes a sub-controller, a temperature sensor, and a snap-fit ​​connector. The sub-controller and the temperature sensor are electrically connected, and the sub-controller and the main controller are wirelessly connected. A micro battery is connected to the sub-controller.

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

[0015] This equipment has a simple structure, consisting only of an operating box, a water temperature simulation chamber, and a temperature detection device. When calibrating the temperature of a passive medical refrigerator, simply attach the refrigerator's built-in digital temperature sensor to the temperature detection device. The device automatically detects the temperature inside the refrigerator and periodically transmits the detected temperature signal wirelessly to the operating box. The temperature is then displayed on the operating box's screen and compared with the data on the refrigerator's built-in temperature display to complete the temperature calibration. Compared to constant temperature test chambers with operating ports, this equipment is simpler to operate and less expensive.

[0035] The usage process of this utility model is as follows:

[0036] Temperature calibration:

[0037] S1: Placement of temperature sensor 3: Slide the latch 333 on the temperature sensor 3 to open the bottom opening of the cylinder 331. Insert the temperature probe of the digital thermometer that comes with the refrigerator into the cylinder 331 through the opening. Release the latch 333, and the latch 333 will reset under the action of the spring, closing the bottom opening of the cylinder 331.

[0038] S2: Low temperature detection operation. Based on step S1, a refrigerant is placed in the refrigerator, the refrigerator lid is closed, and the sub-controller 31 sends the temperature signal detected by the temperature sensor 32 to the main controller at regular intervals. The main controller calculates the temperature indication error of the refrigerator based on the temperature value displayed on the refrigerator and the temperature signal detected by the temperature sensor 32.

[0039] S3: Normal temperature detection operation: Based on step S1, open the lid of the refrigerator to make the temperature inside the refrigerator the same as the outside temperature. The sub-controller 31 sends the temperature signal detected by the temperature sensor 32 to the main controller at regular intervals. The main controller calculates the temperature indication error of the refrigerator based on the temperature value displayed on the refrigerator and the temperature signal detected by the temperature sensor 32.

[0040] S4: High temperature detection operation: Based on step S1, the refrigerator is placed in the inner box 22. The main controller controls the electric heater 23 to heat the water to a certain temperature. At this time, the sub-controller 31 sends the temperature signal detected by the temperature sensor 32 to the main controller at regular intervals. The main controller calculates the temperature indication error of the refrigerator based on the temperature value displayed on the refrigerator and the temperature signal detected by the temperature sensor 32.

[0041] Heat preservation time test: Place the temperature probe of the digital thermometer that comes with the refrigerator inside the temperature detection unit 3, place the refrigerator inside the inner box 22, and the main controller controls the electric heater 23 to heat the water to a certain temperature and start timing. The timing stops when the temperature signal wirelessly transmitted from the temperature detection unit 3 to the operating box 1 reaches a certain threshold, thus completing the heat preservation time test of the refrigerator.
