Technical Field
[0001] This utility model belongs to the field of constant temperature chamber technology, specifically a novel adjustable temperature constant temperature chamber device after limb replantation surgery. Background Technology
[0002] Limb replantation is a highly challenging surgery in orthopedics, and the survival and recovery of the severed limb are closely related to the ambient temperature. A suitable and stable temperature promotes local blood circulation in the severed limb, reduces the risk of vasospasm and thrombosis, and aids in tissue repair and regeneration, thus improving the success rate of replantation. Traditional postoperative care for severed limbs is relatively rudimentary in terms of temperature control, relying heavily on routine room temperature regulation in the ward, which fails to accurately meet the specific temperature requirements of the severed limb. With the development of medical technology and the increasing demands for postoperative care after limb replantation, adjustable temperature incubators have emerged, designed to provide a stable and suitable local microenvironment for the severed limb, ensuring its proper recovery.
[0003] The existing heating and cooling components of the constant temperature chamber are not distributed reasonably, which can easily cause large temperature differences in different parts of the chamber. If different parts of the amputated limb are in different temperature environments, their cell metabolism and tissue repair speed will be inconsistent, which may lead to poor overall recovery of the amputated limb, or even damage or delayed recovery of local tissues due to temperature discomfort.
[0004] To address the problems raised in the background art, those skilled in the art have proposed a novel adjustable temperature constant temperature chamber device for limb replantation surgery. Utility Model Content

Several water-cooled plates are arranged on the side of the temperature regulating tank, and the water-cooled plates and resistance wires are arranged alternately. The water-cooled plates are connected to the water-cooling assembly.

[0027] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0028] Example 1: This utility model provides a novel adjustable temperature constant temperature chamber device after limb replantation surgery, including a chamber body 1 and a temperature control component;
[0029] As attached Figure 1 Appendix Figure 3 Appendix Figure 5 and attached Figure 7 As shown, a drive box 2 is connected to the end of the box 1. A temperature regulating groove 101 is provided in the inner wall of the box 1. The temperature regulating groove 101 is connected to the drive box 2. The drive box 2 can control the box 1. The temperature regulating groove 101 is irregularly ring-shaped and wraps around the periphery of the limb placement part of the box 1. By arranging temperature control components in the temperature regulating groove 101, the temperature control components can be evenly distributed, thereby forming a uniform constant temperature space at the wound.
[0030] The temperature control component includes a heating component and a cooling component, and both the heating component and the cooling component are installed inside the housing 1 and the drive housing 2;
[0031] As attached Figure 5As shown, the heating component includes a resistance wire 7 and an electric heating element 11. The resistance wire 7 is arranged in a ring array in the temperature regulating tank 101. The electric heating element 11 includes a power supply and a temperature controller. The resistance wire 7 is electrically connected to the power supply and the temperature controller respectively. A power interface 14 is provided on the side wall of the drive box 2. By arranging the resistance wire 7 in an array in the temperature regulating tank 101, and with the power supply and the temperature controller, the heating of the resistance wire 7 can be stably controlled, and the temperature can be adjusted to a suitable temperature. By connecting to the power supply through the power interface 14, the heating component can effectively keep the limbs at a temperature suitable for human physiological function in cold environments.
[0032] The cooling component includes a water-cooled plate 8 and a water-cooled component 12. Several water-cooled plates 8 are arranged on the side of the temperature regulating tank 101, and the water-cooled plates 8 and the resistance wire 7 are arranged alternately. The water-cooled plates 8 and the water-cooled component 12 are connected. The cooling component can cool the inside of the box 1 in a high-temperature environment, thereby keeping the limbs at a temperature suitable for human physiological functions.
[0033] As attached Figure 6 As shown, the water-cooling assembly 12 includes a water tank, a water pump, a radiator, a temperature sensor, and a controller. The inner surface of the water-cooling plate 8 is provided with several sealing partitions 9. Two sets of water guide holes 10 are opened on the side wall of the water-cooling plate 8. The water guide holes 10 and several sealing partitions 9 form a water-cooling flow channel. The water-cooling flow channel is connected to the water pump. The side wall of the drive box 2 is provided with heat dissipation holes 13.
[0034] A water pump guides the water cooled by the radiator into the water-cooling channel, where it circulates. The cooled water is evenly distributed within multiple sets of water-cooling plates 8. Since the water-cooling plates 8 surround the limb, the wound area is kept at a stable temperature, ensuring protection of the limb in high-temperature environments. Furthermore, the use of sealing partitions 9 in conjunction with the water-cooling plates 8 ensures the overall sealing performance of the water-cooling assembly 12, preventing abnormal situations caused by water leakage.
[0035] The heat generated by the radiator can be transferred to the outside of the box through the heat dissipation holes 13, effectively ensuring the stability of the radiator's operation.
[0036] A control panel 3 is installed on the upper surface of the housing 1. The control panel 3 is electrically connected to the temperature control component. A support pad 6 is provided on the inner surface of the housing 1. A heat insulation layer 4 is provided between the housing 1 and the drive box 2. The operating temperature of the device can be quickly set through the control panel 3. The support pad 6 can effectively support the limbs. The heat insulation layer 4 can effectively prevent the temperature of the components in the drive box 2 from being conducted into the housing 1, ensuring that the temperature inside the housing 1 is stable.
[0037] As can be seen from the above, in a low-temperature environment, the severed limbs should be properly placed on the support pads 6 inside the box 1 to ensure that the severed limbs are placed stably and in a suitable position so as to be heated evenly.
[0038] Set the target temperature through the control panel 3, for example, to 36℃, which is close to the normal human body temperature and conducive to the recovery of severed limbs.
[0039] The power supply is connected to the drive box 2 through the power interface 14 to power the heating component 11; the thermostat in the heating component 11 controls the resistance wire 7 to start working according to the temperature set on the control panel 3. The resistance wire 7 is arranged in a ring array in the temperature regulating tank 101 and heats up rapidly after being powered on; since the temperature regulating tank 101 is irregularly ring-shaped and wraps around the limb placement part, the heat can be evenly diffused in the box 1.
[0040] As heat dissipates, the temperature inside chamber 1 gradually rises; the temperature sensor monitors the temperature inside chamber 1 in real time and feeds the data back to the control panel 3; when the temperature approaches 36℃, the temperature controller adjusts the power of the resistance wire 7 to maintain the temperature at a lower power, avoiding excessive temperature, providing a suitable warm environment for the amputated limb, and promoting blood circulation and tissue repair of the amputated limb.
[0041] In high-temperature environments, relatively low temperatures are required to prevent limbs from being damaged by overheating;
[0042] When the water-cooling assembly 12 is started, the water pump starts working and the water in the built-in water tank of the water pump is drawn into the water-cooling channel of the water-cooling plate 8. The water-cooling channel is composed of two sets of water guide holes 10 on the side wall of the water-cooling plate 8 and several sealing baffles 9 on the inner surface.
[0043] Cold water circulates within the water-cooled plate 8. Because the water-cooled plate 8 and the resistance wire 7 are alternately arranged around the limb placement part on the side of the temperature regulating tank 101, they can efficiently absorb the heat inside the box 1.
[0044] The temperature sensor continuously monitors the temperature. When the temperature is higher than 36℃, the controller adjusts the water pump flow rate and radiator speed according to the data fed back by the temperature sensor to control the cooling rate. When the temperature drops to 36℃, the water pump flow rate and radiator speed return to normal, maintaining a stable cooling effect and keeping the amputated limb in a suitable low-temperature environment to avoid problems such as cell metabolic disorders caused by high temperature.
[0045] Example 2: As shown in the attached document Figure 4 As shown, a bottom groove 15 is provided on the bottom surface of the drive box 2. An adjustment plate 16 is hinged to the inner wall of the bottom groove 15. A screw 17 is rotatably connected to the top side wall of the bottom groove 15. A slider 18 is threaded around the screw 17. A support rod 20 is hinged between the slider 18 and the adjustment plate 16. One end of the screw 17 extends to the surface of the drive box 2. A knob 19 is fixedly connected to one end of the screw 17.
[0046] As can be seen from the above, the screw 17 can be rotated by the knob 19, the screw 17 drives the slider 18 to slide, and the slider 18 drives the support rod 20 to move, thereby lowering the adjustment plate 16. As the adjustment plate 16 is lowered, the drive box 2 is supported, realizing the adjustment of the support angle of the box 1, which makes it easier for the patient to position the limb and improves the comfort of limb positioning.
