Description

Technical Field

[0001] The present invention relates to the technical field of medical beds, in particular to a multifunctional safety electric bed. Background Art

[0002] Medical bed system is a kind of equipment used to carry patients in hospital wards. At present, medical beds used in hospitals in developed countries are basically automated, and multifunctional electric beds are also used in home beds and community hospital beds. Some medical beds can change their shape through external force to assist in adjusting the patient's position, and some of the accessories have the effect of promoting patient recovery.

[0003] Most of the existing automated beds are mainly designed to facilitate bedridden patients due to physical disabilities to get up, so when designing the bed, an angle-adjustable frame is designed at the head of the bed frame to support the patient, so that the patient can eat or get up conveniently in bed. For example, many patients with physical disabilities have difficulty getting up when they need to go to the toilet due to physical inconvenience, and need help from medical staff or bedside attendants. Automated beds can solve this problem, but most of these patients can still solve the problem of needing to go to the toilet independently by using auxiliary tools (such as crutches, wheelchairs, etc.), while some patients with severe physical disabilities cannot get out of bed to go to the toilet even with auxiliary tools or the help of medical staff. Therefore, a multifunctional auxiliary bed needs to be designed for such patients, so that some patients who cannot get out of bed to go to the toilet can solve the problem of needing to go to the toilet with the help of the bed.

[0016] First, in the present application, the upper body of a patient lying in bed can be raised, allowing the patient to change from a lying position to a sitting position. First of all, this can bring physical benefits to patients who need to stay in bed for a long time, such as facilitating blood return to the heart and reducing the burden on the heart. For example, it can increase the patient's chest cavity volume and lower the diaphragm, which is beneficial to the expansion of the lungs and makes breathing smoother, etc. Secondly, it can also help patients who can get out of bed and move around to get out of bed, such as allowing patients to implement the three-step getting up method, which allows patients to get out of bed in a more comfortable and convenient way. Finally, The patient can change from a lying position to a sitting position by solving the problem of urination and defecation on the bed frame. The bed board of the bed in the present application is provided with bed board holes, in which a bed hole mat or a bedpan can be placed. The bedpan allows the patient to solve the problem of urination and defecation while sitting on the bed, which is a problem that patients lying in bed cannot solve by themselves. The bed hole mat can fill the bed board holes when the patient does not need to urinate or defecate, so that the bed will not make the patient feel uncomfortable when lying in bed due to the bed board holes. The present application solves the problem that the multifunctional beds in the prior art cannot allow bedridden patients to solve the problem of urination and defecation on the bed.

[0017] Secondly, in the present application, the inflatable latex cover arranged on the bed rails can play multiple roles. First, the inflatable latex cover is soft and elastic, which can play a cushioning role and reduce the damage caused by collision to the patient's body, especially for children, the elderly or unconscious patients, and can effectively reduce the risk of injury; secondly, when the patient leans his arms or body on the bed rails, the inflatable latex cover can evenly disperse the pressure to avoid excessive local pressure causing poor blood circulation or indentation, thereby improving the patient's comfort; finally, latex has good air permeability, which allows air to circulate to a certain extent, so that the patient will not feel too stuffy or cold when touching the bed rails, and can regulate the temperature to a certain extent, providing a relatively comfortable body feeling.

[0032] In the present application, a multifunctional bed is designed to facilitate bedridden patients to solve the problem of urination and defecation in the bed. The bed in the present application itself is similar to the bed structure in the prior art, the difference is that the bed head is provided with a lifting and adjusting structure, which can make the upper body of the patient lying on the bed rise, so that the patient can change from a lying position to a sitting position. First of all, this can bring physical benefits to patients who need to stay in bed for a long time, such as facilitating blood return to the heart and reducing the burden on the heart. For example, it can increase the patient's chest cavity volume and lower the diaphragm, which is beneficial to the expansion of the lungs and makes breathing smoother, etc. Secondly, it can also help patients who can get out of bed to move around, such as allowing patients to achieve three The step-by-step getting-up method allows the patient to get out of bed in a more comfortable and convenient way. Finally, allowing the patient to change from a lying position to a sitting position allows the patient to solve the problem of urination and defecation on the bed frame 1. The bed board of the bed in the present application is provided with a bed board hole 12, and a bed hole mat 6 or a bedpan 7 can be placed in the bed board hole 12. The bedpan 7 allows the patient to solve the problem of urination and defecation while sitting on the bed, which is a problem that patients lying in bed cannot solve by themselves. The bed hole mat 6 can fill the bed board hole 12 when the patient does not need to urinate or defecate, so that the bed body will not cause the patient to feel uncomfortable when lying in bed due to the bed board hole 12. The bed in the present application needs to be provided with a mattress matching the bed board when it is used.

[0036] Step 2: Sit for 30 seconds to 1 minute

[0037] After lying flat for 30 seconds to 1 minute, the patient's upper body is slowly lifted by the headboard 11 and then the patient is changed from lying position to sitting position on the bed, and the sitting position is maintained for 30 seconds to 1 minute to allow the brain to adapt to the change from lying position to sitting position and prevent dizziness and discomfort caused by sudden standing.

[0038] Step 3: Stand for 30 seconds to 1 minute

[0039] During the second step, the patient can turn the body so that the legs fall on one side of the bed and touch the ground, and then slowly stand up and maintain the standing position for 30 seconds to 1 minute to ensure that the body has fully adapted to the change in position and avoid symptoms such as dizziness and fainting.

[0040] In this application, the above three steps are used to help the elderly or other people who are prone to falls gradually adapt to changes in body position, thereby reducing the risk of falling due to sudden standing up. When performing these steps, adjustments should be made based on personal health conditions and health needs. For example, people with poor physical conditions or specific diseases can appropriately extend the time of each step, or make corresponding adjustments under the advice of a doctor.
