DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1As shown, a schematic diagram of the structure of the multifunctional wearable pneumatic temperature-controlled blanket of the utility model is given, which is composed of a head air cushion 1, an upper body air cushion 2, two upper limb air cushions 3, two lower limb air cushions 4 and a controller 5. The upper body air cushion 2 realizes the support and bearing of the surgical patient, and the head air cushion 1, the upper limb air cushion 3 and the lower limb air cushion 4 respectively realize the support and bearing and wrapping of the patient. Due to the wrapping effect, a certain degree of heat preservation effect can be achieved for the patient. The head air cushion 1, the upper body air cushion 2, the upper limb air cushion 3 and the lower limb air cushion 4 shown are all composed of a first comb-shaped air cushion 7 and a second comb-shaped air cushion 8 that are interlaced and non-interconnected, as shown in FIG. Figure 2 As shown, a schematic diagram of the composition structure of the upper body air cushion of the utility model is given. The first comb-shaped air cushion 7 and the second comb-shaped air cushion 8 shown are both composed of a plurality of strip-shaped air bags 9, and the strip-shaped air bags 9 are connected through connecting air bags 10.

[0022] The first comb-shaped air cushion 7 and the second comb-shaped air cushion 8 in the head air cushion 1, upper limb air cushion 3 and lower limb air cushion 4 are connected to the first comb-shaped air cushion 7 and the second comb-shaped air cushion 8 in the upper body air cushion 2 through their respective connecting pieces 6. The controller 5 supplies air to the first comb-shaped air cushion 7 and the second comb-shaped air cushion 8 in the upper body air cushion 2 through the first air supply pipe 16 and the second air supply pipe 15 respectively. Due to the connecting effect of the connecting piece 6, the air supply to the first comb-shaped air cushion 7 and the second comb-shaped air cushion 8 in the head air cushion 1, the upper limb air cushion 3 and the lower limb air cushion 4 is also realized.

[0023] In this way, the controller 5 can supply air to all the first comb-shaped air cushions 7 during the process of supplying air through the first air supply pipe 16. When the first air supply pipe 16 changes the gas pressure, the gas pressure in all the first comb-shaped air cushions 7 can also be changed. Similarly, the controller 5 can supply air to all the second comb-shaped air cushions 8 during the process of supplying air through the second air supply pipe 15. When the second air supply pipe 15 changes the gas pressure, the gas pressure in all the second comb-shaped air cushions 8 can also be changed. In this way, by periodically and alternately changing the gas pressure in the first comb-shaped air cushions 7 and the second comb-shaped air cushions 8, the alternating change of the pressure at the patient's pressure site can be periodically changed to improve the blood circulation at the patient's pressure site and prevent the patient from developing pressure sores.

[0024] The head airbag 1 is fixed with a Velcro strap 12, and the head airbag 1 can be wrapped around the patient's head using the Velcro strap 12. The head airbag 1 is in an I-shape, so that after the head airbag 1 is wrapped around the patient's head, the patient's ears, eyes, nose and mouth can be exposed to avoid frostbite of the corresponding parts during cooling. The head airbag 1 is provided with an ice cube placement bag 14. When the patient is a critically ill patient who needs to protect the brain tissue for hypothermia treatment, cooling ice cubes 43 are placed in the ice cube placement bag 14 to maintain the low temperature of the patient's head.

[0025] The head air cushion 1 and the upper limb air cushion 3 are both detachably connected to the upper body air cushion 2 via a hook-and-loop connection belt 11. When the patient does not need the head air cushion 1 or the upper limb air cushion 3, they can be removed from the upper body air cushion 2. The upper limb air cushion 3 and the lower limb air cushion 4 are both fixed with straps 13, which can be used to tie and fix the upper limb air cushion 3 and the lower limb air cushion 4 to the patient's upper limbs and lower limbs.

The controller 5 shown is composed of a shell 26 and a first air pump 27, a second air pump 28, a heating chamber 32 and a control panel 29 arranged in the shell 26. A display screen 18, a pressure and temperature adjustment button 19, a mode selection switch 20 and a power cord 21 are arranged on the shell 26 of the controller 5. The power cord 21 is used to connect to the AC mains to realize power supply to the controller 5. The display screen 18 is used to display temperature and pressure information. The pressure and temperature adjustment button 19 is used to adjust the set pressure value and temperature value. The mode selection switch 20 is used to select between "constant pressure" and "variable pressure" modes. In the "constant pressure" mode, all air cushions are inflated with a constant pressure of a set pressure. In the "variable pressure" mode, after the inflation reaches the set value, the pressure is alternately reduced to no pressure relative to the outside world to realize alternating pressure variation of the first comb air cushion 7 and the second comb air cushion 8 in all air cushions.

The first air pump 27 and the second air pump 28 draw in external air through the first air intake pipe 30 and the second air intake pipe 31 to inflate the air cushion. At the same time, the gas in the air cushion can also be drawn out through the first air intake pipe 30 and the second air intake pipe 31 to reduce the pressure in the first comb-shaped air cushion 7 and the second comb-shaped air cushion 8 in the corresponding air cushion. The first air supply pipe 16 and the second air supply pipe 15 are both provided with temperature sensors for characterizing the temperature of the air cushion.
