Technical Field

[0001] The utility model belongs to the technical field of medical appliances, and in particular relates to a pad for preventing pressure injuries of lower limbs. Background Art

[0002] Pressure injury refers to local damage to the skin and subcutaneous tissue due to pressure or pressure combined with shear force. It usually occurs where the body contacts the supporting surface, such as the heel, sacrum, buttocks, etc., and is mainly manifested by redness, breakage, and even ulcers.

[0003] For patients who are bedridden for a long time, have difficulty in moving, or suffer from certain diseases, due to long-term pressure on the lower limbs, limited mobility, greater pressure on the lower limbs, poor blood circulation and nerve function, they are often prone to heel pressure sores, causing pain to the patients. Currently, in order to prevent patients from developing heel pressure sores, a gel ring or a decompression ring is usually put on the outside of the patient's lower limb, so that the heel is suspended in the air, and the gel ring or the decompression ring can be driven to rotate as the patient's body position changes, which not only prevents pressure injuries on the heel, but also makes it convenient for patients to use.

[0004] Although the gel ring or decompression ring in the prior art can effectively reduce the patient's pressure injury, the size of the gel ring or the decompression ring cannot be adjusted in actual use. When some obese patients use it, since the obese patients' lower limbs are relatively thick, the gel ring or the decompression ring will squeeze the patients' lower limbs, causing discomfort to the patients and weakening the blood circulation in the lower limbs. Therefore, a pad for preventing lower limb pressure injuries is proposed to address the above problems. Utility Model Content

[0010] The beneficial effect of this improvement is that by fixing the square block at one end of the push rod and then making the slide groove guide the square block, the square block can only slide inside the slide groove, avoiding the rotation of the push rod, thereby achieving the fixation of the locking member.

[0011] In order to facilitate fixing the angle between the first connecting part and the second connecting part;

[0012] As a further improvement of the above technical solution: a spring is connected between the inner wall of the slide groove and the square block.

[0013] The beneficial effect of this improvement is that after the angle between the receiving part 1 and the receiving part 2 is adjusted, the square block can be loosened by hand, and at this time, under the elastic action of the spring, the locking rod automatically rebounds into the inside of the socket.

[0014] In order to increase the patient's comfort and facilitate the replacement of the protective cushion;

[0015] As a further improvement of the above technical solution: a protective cushion is detachably connected to the inner wall of the receiving member.

[0016] The beneficial effects of this improvement are: the provision of the protective cushion increases the patient's comfort level, and the detachable connection between the protective cushion and the receiving part facilitates the disinfection and replacement of the protective cushion and the receiving part.

[0017] In order to make the protective cushion adapt to the size change of the receiving part;

[0018] As a further improvement of the above technical solution: the length of the protective cushion is greater than the length of the receiving member.

[0019] The beneficial effect of this improvement is that when the size of the receiving member is changed, since the length of the protective cushion is greater than the length of the receiving member, the protective cushion can fit with the receiving member as the receiving member adjusts its size, thereby avoiding direct contact between the receiving member and the skin.

[0020] In order to facilitate the insertion of the locking rod into the socket;

[0021] As a further improvement of the above technical solution: one end of the locking rod is provided with a cone tip portion, and the insertion hole is provided with a flared portion.

[0022] The beneficial effect of this improvement is that the setting of the conical tip portion on the locking rod and the setting of the flared portion on the socket allows the locking rod to quickly enter the socket when inserted into the socket, avoiding the locking rod from being inserted between two adjacent sockets.
