According to the pressure ulcer prevention electric wheelchair, a patient can control the electric wheelchair to walk through the control switches arranged on one armrest, compression air is introduced into the seat cushion through the air pump switch control arranged on the armrest, and is firstly intermittently delivered into an air flow chamber through an air supply packing auger, then gas is made to enter a vibration chamber by being shunted through the blocking plate, the vibration motor is driven to knock at the surface of a seat cushion bag in the irregular motion direction to massage the hip of the patient, and the patient is effectively prevented from having pressure ulcer.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an anti-decubitus electric wheelchair. Background technique [0002] Electric wheelchairs are upgraded on the basis of traditional manual wheelchairs, using high-performance power drive devices, intelligent control devices, batteries and other components. Extensive, currently the wheelchairs on the market have a variety of functions, some have the function of going to the toilet, assisting in eating, hand and foot massage, and adjusting the function of lying down. However, passengers or patients who cannot stand at all spend almost all day in wheelchairs.

Problems solved by technology

It is characterized in that: the I / O port of the massage control single-chip microcomputer is connected with the air bag control unit, the power inverter unit and the abnormality protection unit respectively; program to drive its various units to work under control; using the technical solution provided by the invention, a large number of electronic control devices are integrated on the electric wheelchair to drive the massage device to massage the patient's buttocks according to the preset program. This technical solution increases the manufacturing cost, and it is difficult to popularize and apply, and the massage method is still set according to the predetermined program. Since the program designer cannot personally feel the pain of the patient, he cannot know the position that the patient needs to massage. However, if the same preset program is used for a long time to massage the patient's buttocks, the massage parts are repeated too much, so that the patient still feels uncomfortable.
