Description

Multifunctional nursing bed

Technical field

The invention relates to the technical field of medical device structural design, in particular to a multifunctional nursing bed.

Background technique

A nursing bed is a bed that is used by patients with inconvenient mobility during hospitalization or home care. Its main purpose is to facilitate the care of the nursing staff and facilitate the rehabilitation of the patient. At present, the nursing bed in the prior art has a single function and can only meet part of the needs of patient care, and the parts of the nursing bed have some limitations. For example, the traditional nursing bed guardrail is inactive, which brings a lot of inconvenience to the nursing staff. In the prior art, there are more active railing-type movable guardrails, which are composed of beams and support columns, which are easy to shake and have low safety and are laid down. It is inconvenient to receive care that affects the caregiver. Moreover, the care bed armrest frame in the prior art is inactive and has limited functions. Another example is that the lumbar support of the nursing bed in the prior art supports the back of the patient, and the patient's body fails to leave the bed and easily causes hemorrhoids.

For example, a multifunctional automatic nursing bed provided by Chinese patent CN103083051A is composed of a chassis, a bed frame, a head bed board, a back bed board, a hip bed board, a leg bed board, a foot bed board, a double folding guardrail, and a toilet folding mechanism. . The back bed plate and the hip bed plate are chain plate type bed plates, and the toilet folding mechanism is installed under the back leg plate of the bed frame. The front double folding guardrail is installed on the front bed plate bracket composed of the head bed plate and the back bed plate, and the rear double folding fence plate Installed on the bed frame. The back plate and the hip plate are chain plate plates. The two plates are longitudinally divided into three blocks, and the middle is a fixed bed plate. The two bed plates on both sides are mounted on the side frame, and the side frame hinges the frame link and the side frame swing arm. The two bed plates on the two sides pushed by the frame electric push rod can be folded upward at any angle of 0-90 degrees. The multifunctional automatic nursing bed utilizes the overall folding movement of the bed board to realize the nursing operation for the patient to turn over and sit up. When the patient is in operation, the patient cannot completely escape from the bed and the ventilation effect is not achieved, and the patient is prone to acne. Moreover, the functional limitations of other parts of the multifunctional automatic nursing bed cannot meet the needs of the patient's daily activities.

For example, a multifunctional nursing bed provided by the Chinese patent CN104257474A includes a bed frame and a bed plate provided on the bed frame, and the bed frame is further provided with a cleaning device for cleaning the patient's urine and urine, and a turning body for driving the patient to automatically turn over. The device and the backing device for driving the patient to automatically sit up, the toilet plate is provided with a hole in the middle of the bed plate and a defecation box is directly below the hole, and the cleaning component comprises an automatic opening and closing hole for sensing the patient's urine and urine And a switch door for supporting the patient, the bed board comprises a first plate area, a second plate area and a third plate area, wherein the back, the buttocks and the legs of the patient are sequentially located in the first plate area, the second board area and the third board On the area, the hole is opened on the second board area. The turning device and the automatic backing device of the multifunctional nursing bed utilize the support of the bed board to realize the turning over and the back, and the patient's body does not leave the mattress when turning over and back, and the effect of completely venting is not achieved, and the acne is easily caused.
