Automatic tuning bed

Abstract

The invention relates to an automatic turnover sick bed, which comprises bed support, motor, connecting rod, lead screw transmitter, friction wheel transmitter, sensor, control circuit, and electromagnetic clutch, wherein the operation panel of control circuit has lifting, lifting incline, bending leg control buttons; when the button is operated, the electromagnet of electromagnetic clutch is powered to absorb the bearing sheath magnet; the inner hole of bearing and the friction wheel step of friction wheel transmitter are fixed with clamping spring; the magnet moves to the electromagnet to slide the friction wheel on lead screw, to match the friction wheel, to provide positive pressure; then starting motor, the lead screw will rotate to move nut on lead screw; the transmitting nut will swing the connecting rod with connecting support; the connecting rod and the clamper form hinge to pushing bed. The invention can realize automatic operation.

Description

【Technical field】 [0001] The invention relates to a medical device, in particular to an automatic turning sick bed capable of controlling motions such as standing up, turning sideways and bending legs. 【Background technique】 [0002] There are about 7 million paralyzed patients in the world, and there are about 1.4 million people in China alone. With the aging of the global population and the continuous improvement of the quality of human life, it is becoming more and more necessary to have a bed that can automatically turn over for paralyzed patients. However, in the hospital at present, many patients, such as coma, hemiplegia, cancer patients, orthopedic patients and other bedridden patients who have been bedridden for a long time, cannot turn over on their own. The resulting lack of oxygen to the tissue can lead to cell death or to the patient's body suffering from very painful bedsores, which in their most severe stages can expose bone and lead to wound infection, which ...

Problems solved by technology

However, in the hospital at present, many patients, such as coma, hemiplegia, cancer patients, orthopedic patients and other bedridden patients who have been bedridden for a long time, cannot turn over on their own. Deprivation of oxygen to the tissue can lead to cell death or painful bedsores on the patient's body, which in their most severe stages can expose bones and lead to wound infection, which can be life-threatening in severe cases

Therefore, turning over bedridden patients every 2 hours is very important to prevent bedsores; in hospitals at all levels, turning over patients with early spinal cord injury, paraplegia and major surgery is also an important nursing work. It is time-consuming and labor-intensive to operate jointly by several nurses, and it is easy to damage the spinal cord again

The existing turning beds are divided into manual type, electric type and remote control type. The manual turning bed requires human manual operation during the whole turning process, which is not cheap for the medical staff, and it is time-consuming and laborious to use. The cost is about 10,000 yuan, and the price is 2,000 yuan; the electric bed is equipped with complex parts such as electric control box, motor reducer, gear, clutch, etc. The bed is very heavy and inconvenient to move, and it is difficult to maintain It is also very inconvenient. The supporting equipment takes up a lot of space, and the cost is generally too high. The cost is about 6,000 RMB, and the price is 8,000 RMB. The price is 40,000 RMB

Therefore, most of the current turning beds with automatic functions are more expensive, ranging from tens of thousands to hundreds of thousands, making it difficult for ordinary families to bear the high cost; manual sick beds are cumbersome to operate and labor-intensive
