Description

Protection device for fixing diabetic foot by using full-contact gypsum

Technical Field

The invention belongs to the technical field of nursing instruments, and particularly relates to a protective device for fixing diabetic feet by using full-contact gypsum.

Background

Full contact gypsum is a gypsum application technology used for helping diabetic foot ulcer healing and protecting fracture malposition of Charcot feet in the early stage. The full contact plaster can realize the distribution of the load on the whole sole to reduce the local abnormal stress, thereby promoting the healing of DFU. The full contact plaster is fully conformed to the outline of the foot, so the name 'full contact plaster'. The full contact of the plaster can evenly distribute the pressure on the sole of the foot and avoid the concentrated pressure on the stressed part. The plaster bandage is shaped completely according to the outline of the foot, from heel to arch and then toe, and fits completely. Therefore, the force-bearing surface is enlarged, and the pressure of the original abnormal force-bearing portion is reduced. The pressure that is originally concentrated on the raised portion of the sole is distributed over the entire sole, thereby avoiding the pressure that is the main cause of ulcer formation.

The traditional method of TCC (total contact plaster) is that a patient lies on the stomach on a plaster bed, the lower leg is upright upwards, a proper thin dressing is selected to cover the patient according to the ulcer wound condition, then a thin-layer tubular bandage is used for protection, a plaster liner is used for protection between toes, the plaster liner is wound up all the way around the lower limb, and the apophysis, the medial and lateral malleoli, the anterior tibia and the like are covered by two layers of foam liners. After the pad is finished, plaster is applied to completely cover toes, feet and lower limbs, and the depressed parts are filled with plaster to make the plaster sole flat.

However, the full-contact plaster is often not accurate enough to make the foot of the patient not uniformly stressed by an empirical method, and the foot of the patient can move in the plaster to cause a new pressure lesion part, and the 3D printing technology can solve the problem, so that it is necessary to design a protective device for fixing the diabetic foot by using the full-contact plaster.
