Problems solved by technology

[0003] However, since the lower limb protectors restrict the movement of the lower limbs, the muscles will not move and cause muscle atrophy. Therefore, it is urgent to propose a lower limb protector that can prevent muscle atrophy, so as to protect the lower limbs from secondary injuries. Prevent and delay lower extremity muscle atrophy

Embodiment 1

[0028] see figure 1 , shows a lower limb supporter in the first embodiment of the present invention, including a thigh support 10 that can be wrapped around the thigh and a calf support 20 that can be wrapped around the calf, and the thigh support 10 is movably connected to the calf support 20 , and in addition, the lower limb supporter also includes an airbag assembly 30 .

[0029] The airbag assembly 30 includes an airbag cushion 31 arranged on the inner wall of the calf support 20, an airbag ring 32 that can be sleeved on the thigh, and a conduit assembly 33 connecting the airbag cushion 31 and the airbag ring 32. The airbag cushion 31 is pre-filled with gas. The catheter assembly 33 is provided with an electric control assembly 34 that can control the gas in the airbag cushion 31 to be inflated into the airbag ring 32 or control the gas to flow back into the airbag cushion 31 .

[0030] Specifically, the catheter assembly 33 includes a main trachea 331 and two bronchi 332...

Embodiment 2

[0035] The second embodiment of the present invention also provides a lower limb supporter. The lower limb supporter in this embodiment is different from the lower limb supporter in the first embodiment in that:

[0036] Since the above-mentioned first embodiment uses the blocking time to control the deflation of the airbag ring, but the influence of the blocking time on the lower extremities is also different due to the differences in the blood and other factors of different patients. If the fixed blocking time is uniformly used, it may cause Some patients have insufficient blocking effect or cause necrosis in some patients. Therefore, in order to solve this technical problem in this embodiment, the lower limb supporter also includes a blood pressure monitoring device (not shown in the figure). The blood pressure monitoring device is used to monitor the venous blood pressure of the lower extremity. The control component 34 controls the gas in the airbag cushion 31 to be inflat...

Embodiment 3

[0040] see Figure 2-Figure 3 , shows the lower limb supporter in the third embodiment of the present invention. The difference between the lower limb supporter in this embodiment and the lower limb supporter in the first embodiment is:

[0041] The airbag cushion 31 is provided with a plurality of airbag chambers 311 spaced in sequence along the axial direction of the calf bracket 20 . The plurality of airbag chambers 311 are sequentially connected from the lower end to the upper end of the airbag cushion 31 , and the main air pipe 331 communicates with the airbag chamber 311 at the lowermost end of the airbag cushion 31 The advantage of the airbag chamber 311 in this layout is that when inflating the airbag ring 32, the gas in the airbag chamber 311 at the lower end is pumped first, and then upwards in turn to form a gradual release from bottom to top, which is related to the blocking of blood flow. The resulting swelling changes correspondingly, and the feeling of comfort i...

Abstract

The invention provides a lower limb protection tool which comprises a thigh support and a shank support which are movably connected, the lower limb protection tool further comprises an air bag assembly, the air bag assembly comprises an air bag cushion arranged on the inner wall of the shank support, an air bag ring capable of being arranged on the thigh in a sleeving mode and a catheter assembly connecting the air bag cushion and the air bag ring, and the air bag cushion is pre-filled with air. The catheter assembly is provided with an electric control assembly capable of controlling air in the air bag cushion to be inflated into the air bag ring or controlling the air to flow back into the air bag cushion. By arranging the lower limb protector capable of preventing and delaying lower limb muscle atrophy, the lower limbs are protected from secondary injury, and meanwhile the lower limb muscle atrophy can be well prevented and delayed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a lower limb supporter. Background technique [0002] In real life, after the lower limb is injured, in order to avoid secondary injury to the lower limb, the hospital usually wears a lower limb protective gear on the injured lower limb of the patient to protect the lower limb through the restraint of the lower limb protective gear, so as to prevent the lower limb from suffering secondary injuries. secondary damage. [0003] However, because the lower limb protector has a certain movement restriction on the lower limb, it will cause the muscles to be immobile and cause muscle atrophy. Therefore, it is urgent to propose a lower limb protector that can prevent muscle atrophy, so as to protect the lower limb from secondary injuries while maintaining a high level of flexibility. Prevent and delay lower limb muscle atrophy. SUMMARY OF THE INVENTION [0004] Based on this, ...
