Description

Technical Field

[0001] The utility model relates to the technical field of equipment calibration, in particular to a wireless temperature calibration device for a blood type card incubator. Background Art

[0002] Blood type card incubators are widely used in hospitals, medical centers, biological laboratories, blood stations, etc. The main function of the blood type card incubator is to incubate the microcolumn gel cards carried by the card box at a timed and constant temperature. During operation, the top surface of the incubator is opened, and the card box containing the microcolumn gel cards to be incubated is placed on the bottom plate of the card box. The inside of the shell is heated by a heating device to maintain a certain temperature. The heating device uses a heating wire and a fan to form hot air heating, and also uses a Kapton heating film attached to the bottom of the metal block for heating. However, due to the lack of a unified calibration method and calibration device, the manufacturer generally only performs point detection on the card slot when leaving the factory. The user will not calibrate the blood type card incubator during use. However, the temperature accuracy of the blood type card incubator will decrease during long-term use. If it is not calibrated, it will affect the blood type test results, thereby affecting blood transfusion and causing serious medical accidents.

[0003] Due to the special card slot design of the blood type card incubator, there is currently no dedicated temperature calibration device. When performing temperature calibration, a patrol meter is used to insert the temperature probe into the incubation card slot, but there are two problems: 1. The probe size does not match the card slot and cannot fit, and is greatly affected by the air. The tested temperature is not the actual temperature state during the incubation of the blood type reagent card; 2. The top cover needs to be opened during use, which is greatly affected by the ambient temperature. Therefore, there is an urgent need for an accurate temperature calibration device that can fit the card slot and is not affected by the external ambient temperature. Utility Model Content
