Description

Technical Field

[0001] This utility model relates to the field of heating and temperature control cabinet technology, specifically a heating and temperature control cabinet for medical care materials. Background Technology

[0002] In medical and nursing care, many nursing materials (such as medical hot compresses, pre-warmed infusion patches, and sterilized instrument packs) need to be maintained at a specific temperature (usually 37-40℃, close to human body temperature) to avoid discomfort caused by low-temperature materials coming into contact with the patient's skin, or to ensure the effectiveness of nursing care (such as the warming therapy effect of hot compresses).

[0003] Currently available medical and nursing material heating equipment has the following shortcomings:

[0004] Poor temperature uniformity: Most equipment uses a single heating source (such as a bottom heating plate), resulting in a large temperature difference between the upper and lower areas inside the cavity, which leads to insufficient or excessive heating of some materials;

[0005] Limited functionality: It can only heat a single type of material and cannot process materials with different storage requirements at the same time (such as dressings that need to be laid flat and instrument packs that need to be breathable).

[0006] Low thermal circulation efficiency: The airflow inside the cavity cannot circulate effectively, and heat tends to accumulate in local areas, resulting in energy waste and poor constant temperature stability.

[0007] Therefore, there is an urgent need for a medical care material heating thermostat that provides uniform temperature, allows for zoned material processing, provides intuitive temperature control, and has high thermal efficiency, in order to address the shortcomings of existing equipment.

[0036] Figures 1-4 The diagram shown is a structural schematic of the first embodiment of a medical care material heating and temperature control cabinet according to this utility model. Please refer to [link / reference]. Figures 1-4 This embodiment of a medical care material heating and temperature control cabinet includes a core structure comprising a shell. Through an internal partition design, multiple heating sources, and an airflow circulation system, it achieves uniform heating and constant temperature maintenance of the care materials. The specific structure is as follows:

[0037] Main structure: Shell 100 and partition design

[0038] The housing 100 is a sealed box structure, internally divided into an upper constant temperature chamber 110 and a lower constant temperature chamber 120. The two chambers are independent and can work synchronously, and can hold different types of nursing materials (such as dressings that need to be rotated and heated in the upper chamber, and instrument packs that need to be stable and breathable in the lower chamber), realizing the function of zoned processing.

[0039] Upper thermostatic cavity 110: Active heating and uniform rotation mechanism

[0040] Drive motor 130: An independent inner cavity installed between the upper constant temperature chamber 110 and the lower constant temperature chamber 120 (to avoid heat directly affecting the motor life), its output axis extends upward into the interior of the upper constant temperature chamber 110 to provide rotational power for the support platform 140;

[0041] The support platform 140 is fixed to the output end of the drive motor 130 and has a circular or square tray structure. It is used to place nursing materials to be heated (such as dressing rolls and small instrument boxes). The drive motor 130 can drive the support platform 140 to rotate at a low speed of 5-10 r / min to ensure that all surfaces of the material are in uniform contact with heat.

[0042] Heating plate 150: It is laid on the surface of the support platform 140 and adopts a silicone heating sheet or metal heating plate structure. After being powered on, it can directly heat the bottom of the material on the support platform 140 to supplement the heat of the side wall heating.

[0043] Heating rods 160: Multiple heating rods (usually 3-4) are provided and evenly distributed on the inner wall of the upper constant temperature cavity 110 (such as the front, back, left, and right sides). When powered on, they release heat to form a surrounding heating environment and prevent the local temperature of the upper constant temperature cavity 110 from being too low.

[0044] Temperature sensor 180: Installed on the top of the upper constant temperature cavity 110, it is used to detect the internal temperature of the upper cavity in real time and provide data support for constant temperature control.

[0045] Lower constant temperature chamber 120: airflow circulation heating mechanism

[0046] Gas distribution seat 170: Fixed to the bottom of the lower constant temperature chamber 120, it is a hollow rectangular or circular structure with multiple evenly distributed air outlets (hole diameter 2-5mm, spacing 3-5cm) on the top, used to evenly transport hot air to each area of ​​the lower constant temperature chamber 120.

[0047] Temperature sensor 180: Installed on the top of the lower constant temperature chamber 120, it has the same function as the temperature sensor 180 in the upper constant temperature chamber 110, and detects the temperature of the lower chamber in real time;

[0048] Airflow circulation assembly: includes a fan 200 and a connecting pipe 210. The fan 200 is fixed to the top of the housing 100. Its air inlet is connected to the upper constant temperature chamber 110 through the connecting pipe 210, and its air outlet is connected to the hollow inner cavity of the air distribution seat 170 through another connecting pipe 210. It can draw the hot airflow from the upper constant temperature chamber 110 to the lower constant temperature chamber 120 to realize the heat exchange between the two chambers.

[0049] Auxiliary structure: sealing and control components

[0050] Sealing door 190: Installed at the openings of the upper thermostatic chamber 110 and the lower thermostatic chamber 120 respectively (connected by hinges). The edge of the door is equipped with a silicone sealing strip. When closed, it can ensure that the chamber is sealed and reduce heat loss.

[0051] Display screen 191: Installed on the surface of the sealed door 190 (usually a touch-screen LCD display 191) to display the current temperature of the upper and lower constant temperature chambers 120 in real time, and can also serve as an operating interface for medical staff to set the target constant temperature value;

[0052] Control system: includes a controller (built into the housing 100, such as a PLC controller), the signal output terminal of the temperature sensor 180 is connected to the controller, and the signal output terminal of the controller is connected to the display screen 191, the fan 200, the drive motor 130, the heating plate 150, and the heating rod 160 respectively, to realize an automated closed loop of "temperature detection-signal processing-actuator control";

[0053] Combination Figures 1-4The working principle of a medical care material heating and temperature control cabinet according to this embodiment is as follows:

[0054] Heating Start-up Phase

[0055] Medical staff open the sealed door 190 and place the materials to be heated into the support platform 140 of the upper constant temperature chamber 110 (such as dressings) and the placement rack (such as instrument packs) of the lower constant temperature chamber 120 respectively. After closing the sealed door 190, they set the target constant temperature value (such as 38°C) through the display screen 191.

[0056] After receiving the target temperature signal, the controller synchronously starts the heating plate 150, heating rod 160, drive motor 130, and fan 200 in the upper constant temperature chamber 110.

[0057] Upper constant temperature cavity 110: heating plate 150 directly heats the surface material of support platform 140, heating rod 160 releases heat to form a surrounding thermal environment, drive motor 130 drives support platform 140 to rotate slowly so that the material is heated evenly on all sides.

[0058] Airflow circulation: After the fan 200 is started, it draws hot air from the upper constant temperature chamber 110 through the air inlet connecting pipe 210, and then transports the hot air to the air distribution seat 170 of the lower constant temperature chamber 120 through the air outlet connecting pipe 210. The hot air diffuses to the lower constant temperature chamber 120 through the uniform air outlet at the top of the air distribution seat 170, heating the material inside the chamber.

[0059] Constant temperature maintenance phase

[0060] Temperature sensors 180 at the top of the upper and lower constant temperature chambers 120 detect the temperature inside the chambers in real time and transmit the temperature signal to the controller.

[0061] When the detected temperature is lower than the target temperature, the controller controls the heating plate 150 and heating rod 160 to increase the power, while keeping the fan 200 speed stable to ensure heat replenishment.

[0062] When the detected temperature is higher than the target temperature, the controller reduces the power of the heating plate 150 and heating rod 160 (or stops heating), while the fan 200 continues to work to maintain airflow circulation in the cavity and avoid local overheating.

[0063] The display screen 191 receives temperature data transmitted from the controller in real time and displays the current temperature of the upper and lower cavities simultaneously for medical staff to monitor in real time.

[0064] Stopping phase

[0065] After the medical staff confirms that the materials have been heated, they turn off the equipment via the display screen 191. The controller simultaneously cuts off the power to the heating plate 150, heating rod 160, drive motor 130 and fan 200.

[0066] Open the sealed door 190, remove the heated nursing material, and then close the sealed door 190.
