Description

Bedsore prevention device and bed

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a bedsore prevention device and a bedsore prevention bed.

Background

Bedsore, also called pressure sore and pressure ulcer, is caused by the fact that the skin of local body is pressed for a long time to influence blood circulation, so that the skin and subcutaneous tissues are lack of nutrition, and the bedsore is damaged, ulcerated and even necrotic, and is better at the pressed bone protrusion part. Bedsores are a common disease, especially in patients who are bedridden for a long time and have weak constitution, and are often caused in the stressed bony prominences, such as sacral coccyx, ischial tuberosity, femoral tuberosity, external malleolus and heel. Most of the anti-bedsore devices on the market are air cushion type, require the air cushion and the air pump to act together, have poor massage effect, and the air pump has noise during working, influence the rest of the patient and is not beneficial to the recovery of the patient

In order to solve the problems, the Chinese patent (publication No. CN106726261A) discloses a bedsore-preventing device and a bed, which comprises a motor, a transmission module and a movement module. The motor is used for driving the transmission module, and the transmission module is used for driving the movement module to move. The transmission module comprises a belt and a belt wheel, and the belt is sleeved on the belt wheel to form belt wheel transmission. The motion module comprises a plurality of moving parts and a plurality of control pieces, the control pieces are distributed along one circle of the periphery of the belt and are fixedly connected with the belt, and the moving parts are movably connected. The movable member is engaged with the control member. The motor drives the belt wheel to rotate, the belt wheel rotates to drive the belt and the control piece to move, and the control piece drives the moving piece to reciprocate in the direction vertical to the belt along with the movement of the belt, so that the moving piece has a massage effect on a patient.

Although above-mentioned scheme is small in noise, and has the function of massage from top to bottom, its massage mode is single, presses a face during the massage, can't press the position, and can't adjust pressing power and frequency, and massage effect is relatively poor, has the limitation.

Disclosure of Invention

The invention aims to provide an anti-bedsore device and a bed, which can meet the requirement of the anti-bedsore device and the bed for fully massaging patients, provide more comfortable experience for the patients and solve the problem that the paralyzed patients are easy to suffer from bedsore.

In order to solve the technical problems, the technical scheme of the invention is as follows:

a bedsore-proof device comprises a shell, wherein a motor is arranged in the shell, a supporting plate is arranged on one side of the motor, the motor is connected with a driving shaft penetrating through the supporting plate, a driving gear is arranged on the driving shaft, a plurality of rotating shafts parallel to the driving shaft are arranged in the shell and are rotatably connected with the shell, a driven gear is arranged in the middle of each rotating shaft, the driving gear is connected with the driven gear through a chain, opposite threads are arranged on the front section and the rear section of each rotating shaft, sliding blocks are respectively in threaded connection with the front section and the rear section of each rotating shaft, a sliding rail corresponding to the rotating shaft is arranged at the bottom of an inner cavity of the shell, the sliding blocks are in sliding connection with the sliding rails, an electric telescopic rod is arranged on the upper side of each sliding block, a lifting plate is arranged on the upper side of the lifting plate in an arc shape, a plurality of pressing blocks are arranged on the upper side of the shell, supporting rods extending into the inner cavity of the shell are arranged at the lower ends of the pressing blocks and are in sliding connection with the shell, the lower end of the supporting rod is provided with a limiting ball.

A bed, comprising the bedsore-proof device.

The principle and the effect of the technical scheme of the invention are as follows:

when the inconvenient motion of patient, when needing the long-time bed treatment, in order to prevent bedsore growth, can let the patient lie this device or install the bed of this device, then start electric telescopic handle, adjust and lift the board height, later starter motor, the motor drives drive shaft and driving gear and rotates, the driving gear passes through the chain and drives driven gear and pivot rotation, and then drive the slider and remove along the slide rail, the slider is along with the rotation direction round trip movement of motor, the slider removes the in-process extrusion and corresponds the pressing piece of point location and moves up, massage the patient.

Compared with the motor, the belt wheel, the belt and the movement module in the prior art, the bedsore-preventing device and the bedsore-preventing bed have the advantages that the massage effect is better, point position massage can be performed, and the comfort level of a patient is higher; the electric telescopic rod is further arranged, so that the height of the lifting plate can be flexibly adjusted, the massage force can be further adjusted, and the electric telescopic rod is wider in applicability; the sliding block is also provided with the arc-shaped lifting plate and the limiting ball, so that the sliding block has smaller interference force and smaller wear in the moving process.

Further, the one end that the motor was kept away from to the drive shaft is equipped with the flabellum, and the casing side is equipped with the guiding gutter that corresponds with the flabellum, and the guiding gutter inboard is opened there is the vent, and a plurality of bleeder vent has all been opened to the casing upside and according to the briquetting.

The motor drives the drive shaft pivoted like this, can drive the flabellum in step and carry out forward, reverse rotation, and in the flabellum corotation inhaled the casing with outside natural wind, the flabellum reversal, the outer gaseous in arranging the casing has promoted the circulation of air in the casing greatly, and the air in the casing passes through bleeder vent and patient's skin contact, provides sufficient oxygen for the pressurized part, has increased the gas permeability, can prevent growing of bedsore.

Furthermore, the sliding blocks on the adjacent rotating shafts are arranged in a relative staggered mode.

When the sliding block slides to massage, the adjacent massage points are staggered, and the massage effect is better.

Furthermore, the slide rail both sides are opened there is the spout, and slider downside both ends all rotate and are connected with the pulley, and the pulley is the level setting, pulley and spout slip joint.

The pulley and the slide rail designed in this way run more stably and smoothly, and the noise is low in the process of moving simultaneously.

Further, an ultrasonic generator is arranged in the shell.

Thus, the ultrasonic generator can be used for emitting ultrasonic waves to massage the patient; the ultrasonic wave acts on human tissues to generate mechanical action, thermal action and cavitation, so that the blood flow of local tissues of a human body is accelerated, the blood circulation is improved, the peristalsis of the blood vessel wall is increased, the permeability of a cell membrane is enhanced, ions are redistributed, the metabolism is vigorous, the hydrogen ion concentration in the tissues is reduced, the pH value is increased, the enzyme activity is enhanced, the tissue regeneration and repair capacity is enhanced, the muscles are relaxed, the muscle tension is reduced, and the pain is relieved or relieved.

Furthermore, a cushion pad is arranged outside the pressing block.

This reduces the pressure on the skin during the massage process by means of the cushion.

Further, still include portable control switch, portable control switch includes motor knob and electric telescopic handle knob.

Therefore, the rotation speed of the motor can be controlled through the movable control switch, so that the massage frequency is controlled, the height of the electric telescopic rod can be controlled, and the massage strength is controlled.
