[0002] Medical carts, also known as treatment carts, are medical devices used for protective transport within patient wards. They are widely used in large hospitals, clinics, pharmacies, psychiatric hospitals, and other similar facilities, and are common mobile carts. They significantly reduce the workload for nursing staff. In practice, treatment carts are often used to transport medications or instruments requiring specific temperature conditions, such as coupling agents and traditional Chinese medicine solutions that need to be kept warm for use, as well as vaccines and live bacteria medications that require low-temperature storage.

[0003] For example, a medical trolley with publication number CN120713720A includes a medical trolley frame, with four casters fixed at the lower corners of the frame, a handle fixed at the upper side of the frame, a brake lever rotatably mounted on the handle, a brake lever wheel coaxially fixed on the brake lever, a mounting plate fixed at the lower end of the frame, a sliding rod inserted into the mounting plate, a spring fitted around the sliding rod, and a brake disc fixed at the lower end of the rod.

[0004] In summary, the following technical problems exist in the existing technology: During the use of the existing technology, medicines are usually stored in conjunction with refrigeration or constant temperature equipment. However, when medical staff open the equipment, they generally need to reach into the trolley to open the equipment and retrieve the stored medicines. The interior space of the trolley is narrow, making it difficult to find the medicines directly. At the same time, directly reaching into the trolley will also contaminate the internal environment.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Example 1

[0022] Reference Figure 1-6 A medical trolley integrating refrigeration and constant temperature control includes two mutually fixed frames 1 and a storage cabinet 2 fixed to one side of the top of the frame 1. Multiple storage drawers 3 are evenly distributed on one side of the frame 1. Multiple medicine storage compartments 4 are opened on the inner side of each storage drawer 3.

[0023] The temperature control mechanism includes a triggering component and an extension component. A baffle 5 is mounted on the inner side of the frame 1. A triggering component is mounted between the baffle 5 and the frame 1, and an extension component is mounted between the triggering component and the frame 1. The triggering component includes a folded plate 6, a vertical groove 7, a first transverse groove 8, a first sliding column 9, a second sliding column 10, and an L-shaped corner plate 11.

The vertical grooves 7 and first transverse grooves 8 are connected. The first sliding column 9 and the second sliding column 10 are slidably connected to the inner side of the vertical grooves 7.

Example 2

[0027] Further optimizations to Example 1, specifically, such as... Figure 2 and Figure 7 As shown, the temperature control device 21 includes a refrigeration device 22, a heating device 23, a humidification device 24, a storage cavity 25, and a dehumidification device. The refrigeration device 22, heating device 23, humidification device 24, storage cavity 25, and dehumidification device are arranged inside the temperature control device 21. The heating device 23 is used to raise the temperature inside the storage cavity 25, the refrigeration device 22 is used to lower the temperature inside the storage cavity 25, the humidification device 24 is used to increase the humidity inside the storage cavity 25, and the dehumidification device is used to decrease the humidity inside the storage cavity 25. A controller 26 is fixed to the top of one of the vehicle frames 1, and an alarm 27 is fixed to the top of each of the two storage cabinets 2. The controller 26 is electrically connected to the temperature control device 21 and the alarm 27 via wires. A support frame 28 is fixed to the top of one of the vehicle frames 1, offset from the controller 26. Multiple file boxes 29 are evenly distributed and fixed to the top of the support frame 28. The heating device 23 typically uses an electric heating element, such as a heating wire or heating tube. When the temperature inside the storage cavity 25 is lower than the set value, the controller 26 triggers the heating device 23 to convert electrical energy into heat energy and increase the temperature inside the storage cavity 25.

[0028] Refrigeration unit 22: Similar to the refrigeration system of a refrigerator, it includes a compressor, condenser, and evaporator. The refrigerant circulates in the system, absorbing heat from the storage cavity 25 through phase change and lowering the temperature.

[0029] Temperature sensor: Installed inside storage cavity 25, it monitors temperature changes in real time and feeds the data back to controller 26.

[0030] Controller 26: Based on the feedback from the temperature sensor, it compares the temperature with the set value and adjusts the operation of the heating and cooling device 22 through a PID algorithm (proportional, integral, derivative control) to ensure that the temperature remains stable within the set range.

[0031] Work process: 1. Heating process: When the temperature sensor detects that the temperature inside the storage cavity 25 is lower than the set value, the controller 26 starts the heating device 23. The heating device 23 starts to work, converting electrical energy into heat energy to increase the temperature inside the storage cavity 25.

[0032] 2. Cooling Process: When the temperature sensor detects that the temperature inside the storage cavity 25 is higher than the set value, the controller 26 starts the cooling device 22, and the compressor starts working, compressing the low-temperature, low-pressure refrigerant into a high-temperature, high-pressure gas. Then, the gas dissipates heat through the condenser, and the refrigerant liquefies. The liquid refrigerant enters the evaporator through a capillary tube or expansion valve, rapidly vaporizes, and absorbs a large amount of heat, thereby lowering the temperature inside the storage cavity 25.

[0033] Humidification device 24: Usually a steam generator or an ultrasonic atomizer is used. The steam generator converts water into water vapor by heating, while the ultrasonic atomizer atomizes water through high-frequency vibration, thereby increasing the humidity in the storage cavity 25.

[0034] Dehumidification device: Using the evaporator in the refrigeration system, the air in the storage cavity 25 is cooled to below the dew point, causing water vapor to condense into water droplets and be discharged outside the storage cavity 25, thereby reducing humidity.

[0035] Humidity sensor: Installed inside storage cavity 25, it monitors humidity changes in real time and feeds the data back to controller 26.

[0036] Controller 26: Based on the feedback from the humidity sensor, it compares the result with the set value and adjusts the operation of the humidifier 24 and the dehumidifier using a PID algorithm to ensure that the humidity remains stable within the set range.

[0037] Work process: 1. Humidification process: When the humidity sensor detects that the humidity inside the storage cavity 25 is lower than the set value, the controller 26 starts the humidification device 24. The water vapor generator or ultrasonic atomizer starts working, converting water into water vapor, increasing the humidity inside the storage cavity 25.

[0038] 2. Dehumidification process: When the humidity sensor detects that the humidity inside the storage cavity 25 is higher than the set value, the controller 26 starts the dehumidification device. The evaporator in the refrigeration system starts working, cooling the air inside the storage cavity 25 to below the dew point, causing water vapor to condense into water droplets and be discharged outside the storage cavity 25, thereby reducing the humidity.

[0039] The controller 26 comprises the following components: Temperature controller: Used to set and control the temperature inside storage compartment 25.

[0040] Humidity controller: Used to set and control the humidity inside the storage compartment 25.

[0041] PID controller: Precisely regulates temperature and humidity and reduces fluctuations through proportional, integral, and derivative algorithms. The user interface is a touchscreen or button-based interface, allowing users to easily set parameters and view operating status.

[0042] Work process: 1. Parameter setting: Users can set the required temperature and humidity values ​​through the operation interface.

[0043] 2. Real-time monitoring: Temperature and humidity sensors monitor the temperature and humidity inside the storage cavity 25 in real time and feed the data back to the controller 26.

[0044] 3. Automatic adjustment: The controller 26 adjusts the operation of the refrigeration device 22, heating device 23, humidification device 24 and dehumidification device according to the difference between the set value and the real-time monitoring value, so as to ensure that the temperature and humidity in the storage cavity 25 are stable within the set range.

[0045] 4. Fault Alarm: When the system detects an abnormal situation (such as sensor failure, refrigerant leakage, etc.), the controller 26 will control the alarm 27 to sound an alarm and stop the operation of the relevant equipment to protect the equipment and samples. Through the synergistic effect of cooling and heating, precise control of temperature and humidity inside the storage chamber 25 is achieved.

[0046] One end of the frame 1 has a receiving cavity 30, and the inside of the receiving cavity 30 is provided with a waste collection drawer 31. A cooling fan 32 is fixed at one end of the frame 1 and at the position corresponding to the temperature control device 21. The cooling fan 32 is connected to the inside of the frame 1. The cooling fan 32 can dissipate heat from the inside of the frame 1, which can make the operation of the temperature control device 21 more stable. Medical waste can be temporarily collected in the waste collection drawer 31 with the help of garbage bags, making the whole cart cleaner.

[0047] In summary: This invention addresses the technical problem of existing technologies that typically use refrigeration or temperature-controlled equipment to preserve medicines. However, medical personnel usually need to reach into the trolley to access the equipment and retrieve the stored medicines. The trolley's interior is cramped, making it difficult to locate medicines directly, and reaching into the trolley can also contaminate the internal environment. The invention employs the technical solutions described in the above embodiments. Furthermore, the implementation process of the above technical solutions is as follows: All electrical components in this device are existing technologies, and their models are only one of them. Any electrical component that can achieve the purpose of this device can be used. Connect all electrical components in the device to their compatible power supply through wires. In addition, a suitable controller should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection between each electrical component should be completed in the order of operation. The detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and will not explain the electrical control. During use, medical staff push the handle of the baffle 5, causing the baffle 5 to move the first sliding column 9 downwards along the inner side of the vertical groove 7, and simultaneously move the second sliding column 10 along the inner side of the first transverse groove 8. This causes the second sliding column 10 to move the L-shaped angle plate 11 along the bottom inner side of the frame 1. When one end of the baffle 5 pushes one end of the transmission rod 16, the transmission rod 16 rotates. Because the strip groove 17 is slidably connected to the second guide column 15, and the second guide column 15 is slidably connected to the second transverse groove 12, the transmission rod 16 can push the second guide column. The movement of 15 causes the return spring 19 to be stretched and deformed. As the second guide post 15 and the first guide post 14 move along the inner side of the second transverse groove 12, the movable plate 13 can move out from the inner side of the frame 1, thus enabling the movable plate 13 to extend. After the movable plate 13 is fully extended, the medical staff take out the medicine from the storage cavity 25, and then pull the handle of the baffle 5 so that the baffle 5 is no longer in contact with the transmission rod 16. At this time, the return spring 19 returns to its original position, which enables the movable plate 13 to drive the temperature control device 21 to move back to its original position until the baffle 5 closes the frame 1.

[0048] With the above-mentioned settings, this application will certainly solve the above-mentioned technical problems, and at the same time achieve the following technical effects: 1. Through the structural design of the temperature control mechanism, the present invention makes it easy to extend the movable plate 13 to the outside by pushing the baffle 5, so that the temperature control device 21 can make it easy for medical staff to intuitively find the medicines stored in the storage cavity 25, thereby speeding up the work efficiency and improving the flexibility of the device.

[0049] 2. Through the structural design of the temperature control device 21, this invention enables the device to adjust the working status of the cooling device 22, heating device 23, humidifying device 24 and dehumidifying device according to the real-time temperature and humidity feedback in the storage cavity 25, so as to achieve precise control of the temperature and humidity in the storage cavity 25. At the same time, it can preset the temperature threshold in the storage cavity 25. When the temperature accidentally exceeds the set threshold, it can remind medical staff through the alarm 27, which is beneficial to use.
