Description

Bed warning medical bed

The present invention relates to a monitoring system for use in a medical bed, and more particularly to a medical bed device having a patient out of bed warning.

With the advancement of medical technology and technology, the average life expectancy of human beings has been extended by 3 to 5 years compared with a decade ago, but as life expectancy increases, it also means that the chances of human illness increase, even though modern medicine can treat Most of the illnesses allow the patient to recover, but before he recovers, the patient still has to undergo a certain medical process to recover.

When the patient's condition is more serious or complicated, some patients must be in bed for medical treatment or observation. Some patients may have difficulty or can't get out of bed. Of course, there are still a few patients who can take care of themselves. It is a place of birth, but the above-mentioned patients still need care or observation from the side of the caregiver or medical staff. Therefore, the workload of nursing or medical staff in the hospital is often becoming more and more important.

According to the statistics of the research center, the number of cases of nursing staff caring for patients will increase the mortality rate of patients within 30 days by 7% for each additional one. If the hospital increases the average number of patients cared for by nursing staff from 4 to 6 Patients will have an opportunity of more than 14% of deaths. If they are added to care for 8 patients, the patient's mortality rate will increase sharply to 31%.

It is conceivable that in the future social pattern of rapid population structure, the number of bedridden patients and bedtime will increase significantly, and the relative demand for nursing staff and care workload will increase a lot. The hospital has a problem of insufficient medical staff.

If a caregiver needs to take care of several patients, for a seriously ill patient who cannot leave the hospital, if the patient accidentally falls over the bed and the safety situation is endangered, the nursing staff is busy taking care of other patients, but I don’t know. If a seriously ill patient falls down the bed, it is easy to delay the first aid and regrets happen. In view of the many inconveniences in the use of traditional medical beds, it is necessary to improve and innovate.

The main object of the present invention is to provide a medical bed capable of monitoring the state of leaving the bed and providing a warning warning.
