Description
Technical Field
The invention belongs to the technical field of rehabilitation equipment, and particularly relates to a bed and a sickbed using the bed.
Background
At present, a hospital bed adopted by a postoperative patient in a hospital, a rehabilitation facility and a home is mainly composed of a bed frame 101, a bedside guardrail 102, a tailstock guardrail 103, a side guardrail 104, a supporting leg 105, a bed board 106 and a pitching mechanism 107 as shown in fig. 1 and fig. 2, wherein the pitching mechanism 107 can adjust one bed board close to the bedside to perform pitching motion so as to assist the patient to keep a sitting posture or adjust to a lying state with the help of other people. For the postoperative patient, although the patient does not lose the ability of behavior, the patient needs to assist the family members and nurses to sit up and turn over in bed due to the conditions of physical weakness, pipeline carrying and the like, the workload of the family members and nurses of the patient is increased to a certain extent, and the waste of medical resources is caused. In the existing medical institutions and rehabilitation institutions, in order to assist patients such as family members and medical staff to turn over, the cloth belts shown in fig. 3 are generally adopted and mainly comprise upper cloth belts 201 positioned at the cervical vertebrae or clavicle positions of the patients at the bed head and lower cloth belts 202 bound on the bed tail; wherein, the upper cloth belt 201 is always positioned between the patient and the mattress, so in order to improve the comfort of the fitting, a silk cloth belt is often adopted; the lower cloth strap 202 is usually made of cloth strips temporarily bound to the bed tail, the two ends of the cloth strips are bound to the bed tail support, and the middle part of the cloth strips freely falls on the quilt for the patient to grasp. However, the bed set can provide certain help to family members and medical staff, but cannot be used by patients independently. For general postoperative patients, although the patients have the problems of weakness, the patients do not lose consciousness and basic behavior ability, but only have insufficient strength.
The prior patent CN110269781B provides a rehabilitation exercise air cushion bed, which is composed of an arm movement device, a leg movement device, a bed body, a massage device and a control box, wherein the arm movement device, the leg movement device and the massage device are respectively arranged at the upper end of the bed body, and the control box is arranged at the lower end of the bed body. The bed board and the bed frame are hinged, so that the adjustment can be carried out according to the body position of the patient, and the inclination degree of the bed board can be more visually seen through the scale plate; the arm motion device can exercise the back-and-forth swing or the up-and-down stretching of the arm, the leg massage device can exercise the knee bending motion and the ankle motion of the patient, and the massage device can massage the back, the hip and the legs of the patient to prevent the muscle atrophy or the arterial varicosity. However, the bed in this patent greatly encroaches on the space on the patient's bed for the patient to lie down, resulting in an obstruction to the post-operative recovery of the patient's mind and body.
The prior patent TW1690314B discloses a sickbed turning device, which comprises two movable protection frames, wherein each movable protection frame is respectively arranged at two opposite sides of a bed, each movable protection frame is provided with a base, a bed rod component, a rolling shaft component and two bed frame clamps, the rolling shaft component can be combined with a lining paper and can roll the lining paper by means of the operation of two motors so as to easily turn over a patient, the bed frame clamps can be arranged on any bed frame, the bed rod component can be overturned so as to conveniently move the patient to get on or off the bed, the movable protection frames can be disassembled and combined, and the movable protection frames can be placed into a containing device, so that the convenient sickbed turning device has the effects of labor saving, convenient assembly and convenient carrying. However, in the patent, the bed sheet needs to be wound to realize the side turning of the patient, which is inconsistent with the regulation in the conventional medical care work, namely the patient needs to move leftwards or rightwards and then turn over in the medical care specification, so that the discomfort of the patient is increased, and the recovery period of the patient is prolonged; meanwhile, the bed sheet folding method adapted to the turning-over device is inconsistent with the conventional folding method, which can cause the rule change of the whole medical system and is not beneficial to the popularization of products.
Therefore, according to the research and study of actual work, it is found that in medical institutions and rehabilitation institutions, a bed tool which can realize the patent functions without increasing the discomfort of patients after operation is needed to assist the patients to realize single-person getting up and lying down and turning over.
