Abstract
Description
Technical Field
[0001] This utility model relates to the field of physical cooling instrument testing technology, and in particular to a physical cooling instrument testing device. Background Technology
[0002] Water-circulating physical cooling devices are common for reducing patient fever and are widely used in clinical treatment. However, their factory testing process has long been plagued by numerous problems. Traditional testing methods often rely on fixed-point measurements using a single temperature sensor, a method that is overly simplistic and limited.
[0003] From the perspective of simulating thermal conduction characteristics, the human body is a complex heat exchange system. Different parts of the body exhibit varying thermal conduction characteristics, and the heat exchange process between the skin and the cooling device is influenced by multiple factors, such as blood circulation and skin humidity. Fixed-point measurements using a single temperature sensor cannot comprehensively and realistically simulate these complex thermal conduction characteristics, leading to significant discrepancies between laboratory test data and actual clinical efficacy. This results in some cooling devices passing all indicators in laboratory testing but failing to achieve the expected cooling effect in actual clinical applications, impacting patient experience and treatment outcomes.
[0004] Furthermore, traditional testing methods lack effective means to detect the vibration and noise generated by physical cooling devices during operation. During operation, internal components such as the water pump and motor of a physical cooling device generate vibration and noise. In a quiet ward environment, excessive noise may disturb patients' rest, affecting their mood and recovery process; while vibration may cause unstable contact between the cooling device and the patient's body, affecting the cooling effect and potentially even impacting the device's lifespan. These problems are particularly pronounced in specialized departments with high environmental requirements, such as intensive care units and neonatal wards. Therefore, we have proposed a physical cooling device testing device to address these issues. Utility Model Content

Detailed Implementation
[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0038] Reference Figure 1-6 The physical cooling instrument testing device includes a testing box body 12. A fixing plate 4 is fixed to the upper end of the testing box body 12. Telescopic mechanisms are connected to both sides of the fixing plate 4. A clamping mechanism is connected to the telescopic mechanism. A vibration detection mechanism is installed on the clamping mechanism. A temperature detection mechanism is connected to one side of the testing box body 12. A noise sensor and a humidity sensor are installed on the side wall of the testing box body 12. The noise sensor can capture various noise signals generated during the operation of the physical cooling instrument in real time and accurately, providing data support for evaluating its quietness during operation. The humidity sensor can monitor the humidity changes of the testing environment, because humidity may have a certain impact on the performance of the physical cooling instrument. By monitoring the humidity in real time, the working condition of the physical cooling instrument under different environmental conditions can be better analyzed.
[0039] A control panel 14 is connected to one side of the detection box body 12. The control panel 14 is connected to the vibration detection mechanism, temperature detection mechanism, noise sensor and humidity sensor. The control panel 14 is the control and data processing center of the entire detection device. It can not only receive data from various sensors, but also analyze, process and display these data. Operators can intuitively understand the various performance indicators of the physical cooling instrument through the control panel 14, and can control and adjust the detection process as needed.
[0040] The telescopic mechanism includes an electric telescopic rod 3 fixed on both sides of the fixed plate 4. One end of the electric telescopic rod 3 is connected to a T-shaped slider 1. The upper end of the T-shaped slider 1 is slidably connected to the top inside the detection box body 12. The electric telescopic rod 3 has a precise telescopic control function, which can accurately adjust the distance between the two clamping plates 2 according to the different specifications of the physical cooling instrument. The sliding connection between the T-shaped slider 1 and the top inside the detection box body 12 ensures the smoothness of the slider sliding and restricts its sliding direction to avoid deviation.
[0041] The clamping mechanism includes a movable plate 6 fixed to the lower end of the T-shaped slider 1. Two guide rods 7 are provided through the movable plate 6. A clamping plate 2 is fixed to one end of the guide rod 7. A spring 9 is sleeved on the guide rod 7. One end of the spring 9 abuts against one side of the movable plate 6. The guide rod 7 provides precise guidance for the movement of the clamping plate 2, ensuring that it will not tilt during the movement. The spring 9 plays a role in buffering and self-adaptation. When clamping the physical cooling device, the spring 9 can be appropriately compressed according to the shape and size of the physical cooling device, making the clamping more stable and avoiding damage to the physical cooling device.
[0042] The vibration detection mechanism includes a silicone pad 8 set on one side of the moving plate 6. Multiple vibration sensors 5 are embedded in the silicone pad 8.

Multiple temperature sensors 16 are evenly spaced on the flexible PCB substrate. The detection cloth 15 has good flexibility and can be tightly wrapped around the cooling band of the physical cooling device to ensure that the temperature sensors 16 can accurately measure the temperature of the cooling band. The use of the flexible PCB substrate not only facilitates the installation and wiring of the temperature sensors 16, but also can adapt to the bending and deformation of the detection cloth 15, ensuring the stability of temperature detection.

The heat insulation layer 10 is made of polyurethane foam material, and the biomimetic thermal conductivity layer 11 is made of silicone-based composite material. The main function of the heat insulation layer 10 is to reduce the heat exchange between the inside and outside of the detection chamber, so as to maintain a relatively stable temperature in the detection environment, thereby improving the accuracy of temperature detection. The biomimetic thermal conductivity layer 11 can simulate the heat conduction mode in the body of organisms, and more effectively conduct the heat generated by the physical cooling device to ensure the thermal balance of the detection environment.
[0045] An opening is provided on one side of the test chamber body 12, and a cover 13 is hinged to the opening. The cover 13 enables the test chamber to form a relatively closed test environment, reducing the interference of external factors on the test results.

By controlling the extension and retraction of the electric telescopic rod 3, the T-shaped slider 1 is moved to slide within the detection box body, thereby adjusting the distance between the two clamping plates 2 to ensure that physical cooling devices of different specifications can be securely clamped.
[0049] 3. Testing stage: Start the physical cooling device and close the cover 13 to create a relatively closed testing environment in the testing chamber. At this time, the testing device begins to monitor the physical cooling device comprehensively.
[0050] Temperature monitoring: Multiple temperature sensors 16 inside the detection cloth 15 collect the temperature data of the physical cooling device's cold compress in real time and transmit the data to the control panel 14;
[0051] Vibration monitoring: The vibration detection mechanism includes a silicone pad 8 set on one side of the moving plate 6. Multiple vibration sensors 5 are embedded in the silicone pad 8. When the physical cooling device is working, the vibration is transmitted to the silicone pad 8 through the clamping plate 2 and the moving plate 6.
