The manufacture and application of modular multi-functional limb protector Wei Liangyun Wang Xiaoning Zhou Jun Jin Sufang Limb fracture is a common and frequently-occurring disease in orthopedics. One of the important factors affecting fracture healing is local blood supply. Because the treatment of fractures often requires internal and external fixators, plaster supports or tubes, splints and other appliances, how to maintain the temperature of the fractured limbs in winter and prevent poor blood circulation is a problem that nursing staff needs to solve. To this end, we have developed a modular multi-functional limb protector, which has been tested in more than 50 clinical cases and achieved good results. Now introduce the following 1 material commercially available cotton (or tarpaulin) styling cotton, Velcro, electric heating elements, thermostat, electric socket, blanket, T-sole (commercially available).
2 Manufacture 2.1 protective cover jacket () Cut the cotton cloth (or tarpaulin) into 2 pieces of ladder-shaped cloth with a length of 40cm, a bottom length of 50cm and a height of 55cm. The upper and the two sides are overlapped and stitched to form a sleeve. Then, two lines are sewed from top to bottom to form a trapezoidal sleeve with three openings (the zipper is opened at the opening), wherein the middle sleeve is 18 cm long and the lower bottom is 22 cm long, and the sleeves on both sides are the same size. Sew 5~6 pairs of Velcro on both sides of the trapezoidal sleeve. The protective cover jacket is mainly used for wrapping the lower part and the two sides of the injured limb, and the sleeve is filled with a cotton or an electric heating pad.
2.2 The upper layer cover () cut the cotton cloth (or tarpaulin) into 2 pieces of ladder-shaped cloth with a length of 18cm, a bottom length of 22cm and a height of 55cm. The upper and the two sides are overlapped and stitched to form a middle tube with the protective sleeve. The sleeves of the same size are mainly used for wrapping the upper part of the injured limb, and the sleeve can be stuffed with styling cotton or electric heating gasket.

Lower bottom limb protective sleeve outer layer cushion cover 2.3 Protection sock () Double cotton socks with cotton cloth (or tarpaulin), middle stopper cotton . The outer layer of the sole is sewn on the T-shaped sole, the outer layer of the sock is zippered on the outer side of the sock, and a curved movable piece is left at the toe, which is sealed with a Velcro fastener and connected to the upper.
2.4 Electric heating gasket () The shape and size of the upper layer is covered by two layers of felt. The electric heating element and the corresponding control circuit are sandwiched between the two layers of felt and fixed on one of the felts.

Thermostat protection sock heating pad 3 How to use each tube according to the temperature, individual difference and comfort requirements Insert a different thickness of styling cotton, or insert the electric heating gasket into the middle sleeve of the upper cushion and/or outer jacket. The patient can be removed during the activity, and the temperature of the electric heating pad can be maintained at 35~40 ° C. For the thinner affected limb, only the protective cover jacket can be used; for the fat limb or the limb with the plaster tube support, splint or traction, Add the upper layer cover. In addition, the upper cushion can also be used alone, padded in the lower part of the limb to relieve the patient's limb compression. The protective sock can be used alone or in combination with the outerwear.
When observing the peripheral blood supply, feeling, and temperature, you can open the curved piece of the toe.
4 Advantages 41 Flexible application, convenient operation and wide application: The limb protector is easy to remove and wash. The shaped cotton (or electric heating sheet) can be thickened and extracted at will. Each part can be used alone or combined according to different needs. Limitations of fracture sites, fat and thin and different treatments.
42 can reduce swelling and pain, promote fracture healing, prevent complications: soft and comfortable styling cotton can reduce limb compression and prevent acne. The constant temperature heating of the electric heating pad can heat the swollen limbs, reduce the swelling and pain of the limbs, promote local blood circulation, accelerate the growth of the bone cells at the fracture end, and promote the early healing of the limbs. At the same time, the T-shaped sole can make the affected limb in a functional position, reducing the occurrence of foot drop and limb tilt.
43 has a certain magnetic therapy effect: the protective sleeve adopts a reasonable circuit design, so that the fractured limb is in the magnetic field, and the magnetic therapy effect is used for a long time, which can accelerate the healing of the fracture. 111 44 ​​can be used in the field: modular structure is easy to fold, easy to carry, detachable and quick to install, easy to install, fast, time-saving and labor-saving, flexible for emergency use in field conditions. Moreover, the protective sleeve has a large room for modification and can be customized according to special needs.
