DETAILED DESCRIPTION

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings in the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application and not all the embodiments. The components of the embodiments of the present application described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, every other embodiment obtained by a person skilled in the art without creative work belongs to the scope of protection of the present application.

[0020] First, the application scenarios applicable to the present application are introduced. The present application can be applied to the technical field of therapeutic instruments.

[0021] The physical compression cold and hot compress therapeutic instrument is a medical device using semiconductor refrigeration technology. Its working principle is that the host adjusts the treatment liquid to a specific temperature through the semiconductor refrigeration sheet, and the working water pump delivers it to the external sheath. The sheath is wrapped around the patient's affected area for cold or hot compress, thereby achieving the treatment effect.

[0022] However, in the existing production and assembly links of the device, due to the different technical levels of personnel or non-standard operation, various hidden faults are easily buried. For example, improper operation may cause hidden damage (such as virtual connection of wires, internal cracks) when installing the semiconductor refrigeration sheet, which may cause it to be unable to run at full power, affecting the temperature rise and fall rate; when installing the water circuit, bending or screwing may occur, causing the pipe to be partially or completely blocked; in addition, the water pump itself may also have faults. These problems will directly affect the treatment liquid circulation and heat exchange efficiency, and ultimately result in abnormal temperature rise and fall rate. The traditional fault diagnosis method needs to detect each module one by one, which is tedious, inefficient and extremely labor-intensive.

[0023] Based on this, the embodiments of the present application provide a therapeutic instrument self-checking method, device, electronic device and medium, which aims to overcome at least one of the above defects.

[0024] Referring to Figure 1 , Figure 1 A flowchart of a self-checking method of a therapeutic instrument provided by an embodiment of the present application. As shown in Figure 1 , the self-checking method of the therapeutic instrument provided by the embodiment of the present application comprises: S101, controlling a heat / radiation pump and a treatment pump of the therapeutic instrument to operate according to feedback data of at least one of a liquid level sensor of the therapeutic instrument, a flow sensor of the therapeutic instrument and a pressure sensor of the therapeutic instrument, to determine whether the water circuit of the therapeutic instrument is working normally.

[0025] Here, the heat / radiation pump and the treatment pump are controlled to operate according to a specific control signal, and the heat / radiation pump, the treatment pump and the water circuit are determined to be abnormal by comparing the predetermined flow sensor value and the pressure sensor value (as shown in the following table).

[0026]

[0027] Specifically, a water circuit diagram of the therapeutic instrument is shown in Figure 2 . The left loop is a heat / radiation water circuit, and the right side is a treatment water circuit. The treatment water circuit is identified according to a sheath, the sheath type is identified, the water amount of the treatment water tank is controlled according to the sheath type, and the water circuit can start the self-checking program through the upper computer after adding water.

[0028] Before step S101, it also comprises: controlling the water pump of the therapeutic instrument to perform forward rotation and reverse rotation operation, and acquiring signal changes of the first liquid level sensor and the second liquid level sensor of the therapeutic instrument in the process of the water pump performing forward rotation and reverse rotation operation; if the signals of the first liquid level sensor and the second liquid level sensor both produce expected changes, it is determined that the liquid level function of the therapeutic instrument is normal.

[0029] Specifically, after manually adding water to the connected main water tank and auxiliary water tank, the change of the first liquid level sensor 1 is observed, and then the change of the second liquid level sensor 2 is observed by adding water through the forward and reverse water pump. If the first liquid level sensor 1 and the second liquid level sensor 2 both change, the test is passed, proving that the liquid level function of the therapeutic instrument is normal.

[0030] S102, after determining that the water circuit is normal, a plurality of semiconductor refrigeration pieces of the therapeutic instrument are started in turn, and the electrical performance parameters and temperature parameters of each semiconductor refrigeration piece when working are collected, and based on the electrical performance parameters and temperature parameters of each semiconductor refrigeration piece, it is determined whether the polarity connection and power output of the semiconductor refrigeration piece are normal.

[0031] Among them, the plurality of semiconductor refrigeration pieces are electrically connected in a series-parallel combination manner.

[0032] Here, since the power of a single semiconductor is limited, the application adopts a combination of series and parallel, and after self-checking starts, each group of semiconductor chips will be opened one by one, the temperature detection plate installed on the water cooling head is used to detect the temperature of the front and back surfaces to determine the polarity of the semiconductor, and the power management chip is used to read the power (voltage and current) of the semiconductor. After testing the polarity and power of all semiconductors, the results are displayed.

[0033] In a preferred example of the application, whether the polarity connection and power output of each semiconductor refrigeration sheet are normal is determined by the following method: The temperature detection unit installed on the water cooling head of the therapeutic instrument is used to collect the temperature of the cold surface and the hot surface of each semiconductor refrigeration sheet to determine whether the polarity connection of the semiconductor refrigeration sheet is correct. The power management chip of the therapeutic instrument is used to collect the working voltage and working current of each semiconductor refrigeration sheet to calculate the actual output power of each semiconductor refrigeration sheet and compare it with the rated power range of the therapeutic instrument to determine whether the power output of the semiconductor refrigeration sheet is normal, so as to screen out semiconductor refrigeration sheets with abnormal power.

[0034] S103, after determining that the semiconductor refrigeration sheet is normal, controlling the therapeutic instrument to perform at least one temperature change cycle to obtain the temperature rise and fall time length, and collecting the temperature data of the temperature sensor of the therapeutic instrument at the target temperature point to determine whether the overall temperature control performance of the therapeutic instrument meets the preset requirements according to the temperature rise and fall time length and the temperature data.

[0035] In a preferred example of the application, the temperature rise and fall time length is obtained by the following method: The therapeutic instrument is controlled to switch from the first temperature stable operating point to the second temperature stable operating point, and the time length required from the start of switching to reaching the second temperature stable operating point is recorded as the temperature rise and fall time length.

[0036] The overall temperature control performance of the therapeutic instrument is determined by the following method: After the therapeutic instrument is stably operated at the target temperature point, a plurality of temperature samples of the therapeutic instrument are collected within a predetermined time period. From the plurality of temperature samples, the average of a plurality of maximum temperature values and the average of a plurality of minimum temperature values are calculated respectively. According to the difference between the two averages, it is determined whether the temperature stability of the therapeutic instrument at the target temperature point meets the requirements.

[0037] Here, after determining that the semiconductor refrigeration sheet is working normally, the overall operation of the therapeutic instrument is controlled to perform systematic temperature performance verification: the target temperature points are set at different temperature values including 4℃, 20℃, 30℃, 35℃ and 42℃; after each target temperature point reaches stability, 300 temperature samples are collected during continuous sampling; then all the temperature samples are sorted, and the arithmetic mean values of the 10 largest and 10 smallest samples are calculated respectively; finally, according to whether the difference between the two arithmetic mean values is within the preset technical requirement range, it is judged whether the temperature stability of the therapeutic instrument at the target temperature point is qualified.

[0038] After the above self-checking method is implemented, a performance parameter report is printed, avoiding the hidden danger of single device inspection qualified and then failure again, and improving the overall qualified rate and production inspection efficiency.
