[0026] Embodiment 1

[0027] A pneumatic limb circulation promoting device comprises a control end 1 and an output end 2, wherein the control end 1 is the control part of the whole device, comprising a main control board 3, a negative pressure pump 4, a touch display device 5, an air pressure sensor 6, a three-way valve 7, and an air filter element 8; the output end 2 is the output part of the device, which is mainly responsible for contacting with the patient's skin surface to output airflow or release air, forming a negative pressure space, and promoting lymph circulation; a main airway pipeline 9 is provided between the control end 1 and the output end 2, which is used to form an effective airflow channel and to connect the output end 2 and the control end 1;

[0028] At the output end 2, the main gas pipeline 9 is divided into a deflation pipeline 10 and an intake pipeline 11. The deflation pipeline 10 is used to adjust the pressure in the negative pressure cavity 12. When the pressure in the negative pressure cavity 12 is too high, deflation is performed to reduce the pressure. The outer shell of the output end 2 is composed of a handheld portion 13 and a negative pressure cavity 12 portion. The handheld portion 13 is a handheld end for medical staff. The medical staff holds or clamps this portion and gradually brings the negative pressure cavity 12 portion close to the patient's skin for nursing work. The negative pressure cavity 12 portion is made of transparent material, and the side adopts a V-shaped structure, which is convenient for adsorption and collection. This structure is convenient for adsorption and is beneficial to protecting the patient's skin without causing obvious indentations.

[0029] Specifically, an infrared distance sensor 14 is installed in the housing of the handheld part 13. When the adsorption pressure is too large, the distance between the infrared distance sensor 14 and the patient's skin will trigger a warning. The infrared distance sensor 14 transmits a signal to the main control board 3, and the main control board 3 reduces the pressure output by partially deflation or stopping the negative pressure pump 4.

[0030] Specifically, a main control board 3 is arranged inside the control terminal 1, and one end of the main control board 3 is connected to a touch display device 5, which is a touch display screen and can be used as an input or display terminal, mainly displaying various parameters; the other end of the main control board 3 is electrically connected to an air pressure sensor 6, an infrared distance sensor 14, an electric control valve 15 and a negative pressure pump 4, and controls them; at the same time, the power supply of the device is connected to an external power supply through a power adapter 16;

[0031] When in use, the user presses the touch display device 5 to start the negative pressure pump 4, and presses the negative pressure cavity 12 on the skin, and at the same time, the skin is adsorbed by pumping air. When the pressure is too high, the deflation pipe 10 is adjusted to deflate. Between suction and discharge, the circulation of endolymph fluid in the limbs is promoted. The overall volume is small and easy to carry, and it is suitable for different scenes.

[0032] The distance between the skin and the infrared distance sensor 14 is monitored in real time. If the distance is too close, the negative pressure pump 4 is controlled to deflate to adjust the adsorption strength.

[0033] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
