The use of a large amount of liquid is usually heated and insulated by devices such as a constant temperature cabinet, but this heating method cannot precisely control the heating temperature. Precise temperature control of the liquid is required in some surgeries. For example, in cartilage repair surgery, the buffer solution is first heated to an appropriate temperature (such as human body temperature), and then the enzyme is inserted and the cartilage tissue removed from the patient is used for the enzyme reaction. , to decompose cartilage tissue to obtain cartilage cells covered by cartilage tissue, and then the step of implanting cartilage cells can be carried out.

However, most of the heating methods used in the above-mentioned situations still use a water bath for heating. Since the water bath is not usually placed in the operating room, the buffer solution needs to be heated outside the operating room and then manually moved into the operating room. This heating method can greatly increase the risk of surgical infection by causing the buffer to become contaminated due to uncleaning of the water bath or during movement. Therefore, there is an urgent need for a heating device that can be sterilized and disposed of to effectively reduce the possibility of infection.

FIG. 4 is a block diagram of the second embodiment of the dry heating device according to the present invention. In the second example, the connection relationship of each element is similar to that in the previous embodiment, and will not be repeated here. The main difference from the first embodiment is that the dry heating device 101 proposed in the second embodiment further includes a warning element 190 .

It can be seen from FIG. 1 , FIG. 2 and FIG. 4 , when the user uses the second heating tank 120 to heat, and after the timer element 180 counts down for 20 minutes, the timing element 180 will transmit the second timing completion signal 182 to the processing module 170 . , the processing module 170 transmits the first warning signal 178 to the warning element 190 based on the second timing completion signal 182 , and the warning element 190 will emit a warning sound at a first predetermined interval (for example, 2 seconds) until the processing module 170 receives the fourth detection signal After 142, the processing module 170 will transmit the second stop signal 177 and the third stop signal 179 to the second heating control element 160 and the warning element 190, respectively, to stop the heating and warning operations. However, the present invention is not limited to this, that is to say, the warning element 190 can also set the warning status according to the needs of the user.
