Multi-functional air inflation lower limb abduction pillow

Abstract

A multi-functional air inflation lower limb abduction pillow is characterized by comprising a ladder-shaped pillow and a lower limb cushion. The ladder-shaped pillow comprises an antiparallelogram pillow body made of a flexible material and a fixing belt arranged on the antiparallelogram pillow body. Grooves with arc-shaped sections are arranged on two lateral walls of the antiparallelogram pillow body, and the sizes of the grooves are matched with those of human body lower limbs. The lower limb cushion comprises a base pad matched with the human body lower limbs and a vertical pad arranged outside the base pad, and an inner side of the vertical pad is in a shape of an inner concave arc face matched with the outside of the human body lower limbs. Compared with the prior art, the multi-functional air inflation lower limb abduction pillow has the advantages that during use, portions below knee joints are not easy to move, the pillow is comfortable, and side effects are small.

Description

Technical field: [0001] The invention relates to a medical device. Background technique: [0002] In order to prevent prosthetic dislocation after hip replacement, there are strict requirements on the patient's body position within 3 months after surgery, and different body positions must be adopted according to different surgical approaches: postoperative flexion greater than 90° should be avoided after posterolateral approach And excessive rotation, adduction; external rotation should be avoided after anterolateral approach surgery. [0003] In order to maintain this special treatment position, the current common clinical method is to put a soft pillow under the knee joint of the affected limb when the patient is in the supine position after operation, wear a neutral T-shaped shoe for the affected limb, and place a trapezoidal pillow between the legs , to maintain the neutral position of the affected limb and abduct 15 to 30 degrees, while avoiding external rotation, addu...

AI Technical Summary

Problems solved by technology

Trapezoidal pillows are mostly made of sponge or cotton. Neutral T-shaped shoes are mostly made of wood strips plus cloth shoes or made of plastic molds. Pillows under the knee joints are mostly made of sponge or cotton and air pillows; trapezoidal pillows, The soft pillow under the knee joint and the neutral T-shaped shoes are independent parts. However, in the clinical practice of this method, it is found that the soft pillow under the knee joint is easy to shift during use, and the two sides of the trapezoidal pillow placed between the legs are Right-angled, the calf part is uncomfortable. When the affected limb wears a neutral T-shaped shoe, the cleanliness, comfort and air permeability of the patient's foot are reduced, and it is easy to cause pressure sores on the heel. At the same time, the object is bulky and inconvenient to carry
