Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a nursing bed capable of realizing out-of-bed alarm. Background Technique

[0002] Clinically, due to disease factors, the physical condition of inpatients, such as after radiotherapy and chemotherapy, significantly declines. For example, hypoglycemic patients may experience dizziness, and transient hypotension may occur when changing body positions when getting up. These phenomena make it easy for patients to fall beside the bed when getting out of bed, endangering their safety. For elderly people with limited mobility, it is even more likely to occur when getting up or getting out of bed. Therefore, sufficient attention should be paid to the falls of elderly patients and patients with dementia, especially, and prevention should be emphasized. The purpose of prevention is to prevent the risk of patients falling without interfering with their daily activities and autonomous functions.

[0003] Currently, most hospital ward beds are designed with bed rails, and the bed rails of the beds usually need to be manually pulled up or down.

[0004] However, the accompanying family members and medical staff cannot always monitor whether the patient gets out of bed. Therefore, it is necessary to design a device for monitoring patients. CN211382323U discloses a hospital bed with a bed rail alarm. A touch rod is vertically arranged at the bottom of one end of a cross bar. This end is the end where the cross bar is staggered from the vertical bar after folding. A receiving groove is opened on the upper surface of the bed body opposite to this end, and a switch button is arranged in the receiving groove. The switch button is touched by the touch rod inserted into the receiving groove when the cross bar is folded. The switch button is connected to a controller, and the controller is connected to an alarm. The alarm and the controller are both arranged on the bed body, which can monitor the placement situation of the guardrail and improve the safety of using the hospital bed. However, for CN211382323U, the touch rod and the switch button will still come into contact and trigger an alarm when the accompanying family members and medical staff do not need an alarm beside the hospital bed.

[0005] Therefore, there is an urgent need for a nursing bed that can realize controllable out-of-bed alarm. Content of the Utility Model
