Description
Technical Field
The utility model relates to the technical field of medical equipment, especially, relate to a wheelchair pad of cushion and back of the body pad components of a whole that can function independently heating.
Background
The patient lacks exercise in the wheelchair and the ability to self-regulate body temperature is reduced. The patient sitting on the wheelchair for a long time has the problem of hypothermia, which is not favorable for the recovery of the body health of the patient. People generally adopt a mode of heating the wheelchair cushion to keep the temperature of patients. The heating of the wheelchair cushion in the prior art mostly adopts an integral heating wire heating cushion. The wheelchair cushion can not realize the split control of the cushion and the back cushion, has low thermoelectric conversion efficiency and poor use comfort. Therefore, there is a need to provide a new wheelchair cushion to solve the above-mentioned technical problems.
Disclosure of Invention
The utility model provides a technical problem lie in providing a cushion and back of the body fill up wheelchair pad of components of a whole that can function independently heating, this wheelchair pad separately sets up cushion and back of the body pad and all can independently move, and heating part adopts flexible graphite alkene heating film heating, has safe comfortable, the electric heat conversion rate is high, convenient to use's advantage.
In order to solve the technical problem, the utility model adopts the following technical scheme: the utility model provides a cushion and back of body pad components of a whole that can function independently heating's wheelchair pad which characterized in that: including cushion and the back of the body pad that can independent operation heating, adopt zipper device to connect between cushion and the back of the body pad, cushion and back of the body pad all include the ventilative cloth overcoat of sandwich, are located flexible graphite alkene heating film and the ventilative foam-rubber cushion in the ventilative cloth overcoat of sandwich, and flexible graphite alkene heating film is located and presses close to the front of health, and ventilative foam-rubber cushion is located and presses close to the back of wheelchair, and the flexible graphite alkene heating film of cushion and back of the body pad all is equipped with circuit connection plug, and circuit connection plug passes through the wire and is connected with the controller, and the controller passes through the wire and is connected with safety power supply.
Furthermore, a temperature sensor is arranged on the flexible graphene heating film.
Furthermore, the controller comprises a single chip microcomputer, an A/D converter connected with the single chip microcomputer, a key, an LCD display and a relay trigger circuit, and the relay trigger circuit is connected with circuit connecting plugs of the cushion and the back cushion through two wires respectively.
Compared with the prior art, the wheelchair of cushion and back of the body pad components of a whole that can function independently heating is filled up, separately sets up cushion and back of the body pad, all sets up the flexible graphite alkene heating film of independent operation on cushion and the back of the body pad, and cushion and back of the body pad can the exclusive use also can the simultaneous use. When the cushion and the back cushion are used simultaneously, the heating states of the two parts of flexible graphene heating films can be controlled independently, and a user can have more choices. The heating of flexible graphite alkene heating film is compared and is felt more comfortable in other modes of generating heat, and electric heat conversion efficiency is higher. The utility model discloses utilize the low voltage power supply to supply power, can ensure bed personnel's absolute safety, by the temperature of the flexible graphite alkene heating film of temperature sensor perception, utilize the controller to control the heating state of flexible graphite alkene heating film, it is more convenient to use. The utility model discloses utilize the principle of generating heat of flexible graphite alkene heating film under the low electric field effect, the far infrared thermal radiation that sends is deepened and is conducted inside the skin, more does benefit to the personnel of lying in bed recovered.
