Generally, the lid of the incubator is a single piece, with operating openings on both sides. The lid and bottom are detachable for easy opening and operation.

[0003] Existing technology uses temperature-conducting plates to control temperature, which means that even with ventilation holes, insufficient oxygen is still a possibility.

[0004] As disclosed in Chinese Patent CN213964110U, a newborn transport incubator mattress is designed with a first air tube, an auxiliary air cushion, a patch, and a sponge pad. The newborn is placed on the sponge pad, and the auxiliary air cushion is located below the sponge pad. The auxiliary air cushion is relatively soft and suitable for transporting newborns. The auxiliary air cushion is inflated through the first air tube to assist in securing the newborn with the anchoring strap at an appropriate distance, providing a good environment for the newborn and achieving the goal of making the newborn more comfortable and ensuring safety during transport.

[0005] However, the constant temperature heating structures used in existing technologies are usually internal heating structures, and they achieve good heat preservation by using sealing. However, this can easily lead to insufficient air circulation, resulting in insufficient internal oxygen.

[0006] Therefore, we urgently need to provide a constant temperature transport bed for newborns. Summary of the Invention

[0007] The main objective of this invention is to provide a neonatal constant temperature transport bed that can effectively solve the problems mentioned above.

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] Example 1, as Figures 1-6 As shown, a neonatal constant temperature transport bed includes a bed body 1, a constant temperature mechanism 2 installed at the bottom of the bed body 1, a heat preservation mechanism 3 installed at the top of the bed body 1, and a buffer mechanism 4 installed inside the bed body 1.

[0030] The constant temperature mechanism 2 includes a heating box 21. A fan 22 is installed inside the heating box 21 near the front end. A filter plate 23 is installed inside the heating box 21 near the back end. A heating plate 24 is installed in the middle of the heating box 21. An air supply pipe 25 is connected to the middle of the front of the heating box 21. A guide shroud 26 is connected to the end of the air supply pipe 25 away from the heating box 21. A return pipe 27 is installed in the middle of the back of the heating box 21. A battery compartment 28 is installed at the bottom of the heating box 21. A controller 29 is installed in the middle of the right side of the bed 1 near the bottom.

[0031] The heating box 21 is fixedly installed in the middle of the bottom surface of the bed 1. The outer surface of the filter plate 23 is slidably connected to the inner wall of the rectangular hole on the left side of the heating box 21. The outer surfaces of the air supply pipe 25 and the return pipe 27 are connected to the inside of the round hole at the bottom of the bed 1. The air guide shroud 26 is fixedly installed inside the bed 1.

[0032] The heating plate 24 is equipped with S-shaped heating wires made of nickel-chromium alloy with a rated power of 50-80W. The outer surface of the heating plate 24 is covered with a high-temperature resistant insulating ceramic layer. The filter plate 23 has a solid ABS plastic frame and is equipped with three layers of filter screens, from the outside to the inside: a primary filter screen (50μm pore size), a medium-efficiency filter screen (10μm pore size), and a high-efficiency filter screen (0.3μm pore size). Granular activated carbon is filled between the medium-efficiency filter screen and the high-efficiency filter screen as an adsorbent filler. The controller 29 is an embedded single-chip microcontroller, model STM32F103, with an LCD display and temperature adjustment buttons (adjustment range 32-36℃, step size 0.5℃). The controller 29 is electrically connected to the heating plate 24 and the fan 22 via wires. An NTC thermistor temperature sensor is installed inside the bed 1 near the inner wall of the insulation cover 33. The temperature sensor is connected to the controller 29 to detect the internal temperature of the bed 1 in real time and feed it back to the controller 29. The control logic of the controller 29 is as follows: when the detected temperature is lower than the set temperature by -0.3℃, the heating plate 24 and the fan 22 are activated; when the detected temperature is higher than the set temperature by +0.3℃, the heating plate 24 is turned off, and the fan 22 switches to low speed to maintain air circulation. Two parallel lithium batteries are installed in the battery compartment 28, which can provide a battery life of ≥8 hours to meet the needs of short-distance transportation. When the battery is low, it can be charged through the Type-C charging interface.

[0033] The designed constant temperature mechanism 2 uses heating plate 24 for heating, and fan 22 circulates hot air through air supply pipe 25, air guide 26 and return pipe 27, thereby ensuring internal air circulation while maintaining temperature.

[0034] During use, the temperature is set by the controller 29, which heats the heating plate 24. The fan 22 transports the heat, and the hot air enters the bed 1 through the air supply pipe 25. When the hot air enters the bed 1, the guide hood 26 guides the hot air, allowing the heat to flow along the heat insulation cover 33, effectively preventing the hot air from blowing directly on the newborn. The air inside the bed 1 flows back to the heating box 21 through the return pipe 27, thus completing the circulation of heat and ensuring a constant temperature. Since the heating box 21 has several ventilation holes on the left side, it ensures the circulation of fresh air. The filter plate 23 effectively filters the circulating air, preventing dust and impurities from entering the interior and affecting the health of the newborn.

[0035] Example 2: A neonatal constant temperature transport bed, the heat preservation mechanism 3 includes a sealing groove 31, a sealing gasket 32 ​​installed inside the sealing groove 31, a heat preservation cover 33 connected to the side of the sealing gasket 32 ​​away from the sealing groove 31, handles 34 installed in the middle of the left and right sides of the heat preservation cover 33, a limit ring 35 installed on the top of the heat preservation cover 33, and a movable cover 36 slidably connected inside the limit ring 35. The heat preservation cover 33 is made of transparent material, the bottom of the heat preservation cover 33 is snapped into the inside of the sealing groove 31, and the sealing groove 31 is fixedly installed on the outer surface of the bed 1.

[0036] The limiting ring 35 is fixedly installed on the top of the heat insulation cover 33, the bottom surface of the movable cover 36 is slidably connected to the top of the heat insulation cover 33, and the top of the heat insulation cover 33 has an operation port.

[0037] The buffer mechanism 4 includes a spring damping rod 41, a support plate 42 is mounted on the top of the spring damping rod 41, an air cushion 43 is mounted on the top of the support plate 42, and an insulation pad 44 is mounted on the top of the air cushion 43. The bottom end of the spring damping rod 41 is fixedly connected to the inner bottom surface of the bed frame 1, and the air cushion 43 is filled with dry and clean air.

[0038] The sealing gasket 32 ​​is made of medical-grade silicone with a Shore hardness of 30-40°. The damping coefficient of the spring damping rod 41 is 5-8 N·s / m, and the spring elasticity coefficient is 10-15 N / mm. There are 4 rods, which are installed at the four corners of the bottom of the support plate 42. The heat insulation pad 44 is made of an inner layer of medical cotton and an outer layer of waterproof and breathable non-woven fabric, and the surface is provided with breathable holes.

[0039] The heat preservation mechanism 3 and the buffer mechanism 4 are designed to improve the heat preservation effect by using the heat preservation cover 33. The heat preservation cover 33 is easy to disassemble and the movable cover 36 is easy for medical staff to operate on the newborn. The spring damping rod 41 and the air cushion 43 can effectively ensure the comfort of the newborn during the transfer.

[0040] After the newborn is placed inside the bed 1, the heat insulation cover 33 is engaged with the sealing groove 31 to reduce internal heat loss. The sealing gasket 32 ​​installed inside the sealing groove 31 effectively ensures the seal at the connection. The movable cover 36 slides in the gap between the limiting ring 35 and the heat insulation cover 33, making it easy for medical staff to operate on the newborn through the operating port on the top of the heat insulation cover 33. The heat insulation cover 33 can be quickly disassembled or installed by pulling the handle 34. After the newborn is placed inside the bed 1, the installation of the spring damping rod 41 and the dry, clean air filling the air cushion 43 can cushion the bumps during transportation. At the same time, the dry, clean air filling the air cushion 43 and the installation of the heat insulation pad 44 can effectively reduce heat loss and improve the heat preservation effect. The heat insulation pad 44 on the top of the air cushion 43 is made of medical cotton and waterproof and breathable non-woven fabric, which can reduce heat loss from the newborn's body surface and ensure breathability to avoid stuffiness and discomfort.
