Description

A multifunctional massage bed for patient care with electric back lift and leg flexion

technical field

The invention relates to a patient bed, more specifically, to an electric multifunctional massage bed for patient care with back lifting and leg flexion.

Background technique

The traditional patient care bed includes a bed frame and a bed panel supported on the bed frame. The bed panel is usually a fixed board. The patient can only stay in the same position for a long time when lying in bed, that is, the state of lying flat, which is prone to decubitus and other diseases. And can cause the bodily function degeneration of patient, also bring larger workload to nursing staff simultaneously, and labor intensity is big.

In view of the problems referred to above, a new type of nursing bed has appeared on the market, which can improve the patient's self-care ability, reduce the work intensity of the nursing staff, and reduce the worries of family members. At present, most of these new nursing beds can be divided into two types, one is hand-cranked and the other is electric. The above two nursing beds basically have the following functions: 1) The backrest can be lifted and lowered to allow patients to sit and lie down. Adjustment; 2) The legs can be set up and down to realize the adjustment of the flexion and extension of the patient's legs; 3) The bed body can be set up and down, which is convenient for the work needs of medical staff.

With the continuous improvement of people's life expectancy, the aging population in society is increasing, and the demand for nursing beds for the elderly is also increasing. With the development of technology and the society's more attention to the elderly, there are more and more functional nursing beds, which provide various conveniences for the life of the elderly and the treatment of patients.

However, most of the current nursing beds use electric or manual methods to drive the corresponding parts of the bed board to move through the transmission chain, so that the human body is in postures such as sitting, lying, and lying; The corresponding part of the bed board moves to realize the position change of the bedridden person. The nursing bed of above-mentioned two kinds of structures generally all has the following defects:

(1) Using chain drive or connecting rod mechanism, the movement noise of the bed body is large, and multiple bed boards are connected by hinges. After a period of non-use, there will be a lot of noise when turning;

(2) It is driven by a servo motor. Due to the high price of the servo motor, the cost of the electric nursing bed is too high and it is difficult to promote;

(3) The transmission structure is relatively complex, prone to failure, and inconvenient to repair;

(4) The distance between the bending point of lifting the back and the bending point of the knees is fixed, which is difficult to be used by people of different heights. It is easy to find that the position of lifting the back is more comfortable, while the position of bending the legs is too far or too close, resulting in the inability to fully bend the legs or A condition in which the support of the thigh is reduced without discomfort.

In addition, for paralyzed patients, they usually have no ability to take care of themselves and need to lie in bed for a long time. Lying for a long time can easily cause pressure on the skin, ischemia and necrosis of subcutaneous tissue and muscles, and form bedsores. Massage is beneficial to promote blood circulation, promote venous return, promote metabolism, improve nerve function, prevent muscle atrophy and joint stiffness, and avoid the formation of bedsores. Therefore, patients with complete paralysis should be helped by nursing staff and family members to perform passive body movements and muscle massage. Generally, it takes 10 to 20 minutes each time, 2 to 3 times a day, which brings great trouble and labor intensity to medical staff and family members.

At present, in order to reduce the labor intensity of medical staff and patients' family members and improve the work efficiency of medical staff, many massage devices for paralyzed patients have appeared on the market, and have brought certain effects to the treatment of paralyzed patients. Many existing massage beds adopt the human body to lie flat on the bed body, and the massage device is arranged at the lower part of the bed body to massage the back of the human body. And the mechanical force method of massaging protrusions on the rolling wheel, by applying pressure on the meridians of the human body and stimulating various receptors, it can put pressure on hundreds of acupuncture points and meridian points all over the body, and exert pressure on the sore and numb muscles of the back, waist, and legs. Traction, extrusion, kneading and other whole body massage can gently stimulate the muscles, and massage the key parts back and forth repeatedly, so as to restore the fiber elasticity of the muscles, accelerate the blood circulation speed, adjust the balance of yin and yang in the human body, balance the circulation of qi and blood, and strengthen the viscera function, to promote the health of the human body, but the massage bed using this method, due to the weight of the human body, the massage device generally cannot control the massage force well, and cannot fully contact some parts of the body, so the massage parts are not comprehensive, and the massage method Single, the human body comfort level is low.
