Description

Lifting guardrail for bed

Technical Field

The utility model belongs to the technical field of bed guardrails, and particularly relates to a lifting guardrail for a bed.

Background

Fall of inpatients is one of common nursing adverse events, and fall/falling prevention management of inpatients is always a focus of attention in the fields of medical treatment, nursing and rehabilitation at home and abroad. Literature shows that falling down is very easy to happen during hospitalization of patients, the falling down is a common safety problem for hospitalized patients, and falling down has become an important cause of non-lethal injury and death for the elderly. Cerebral apoplexy hemiplegia patient and tumour patient who has dyskinesia and consciousness disturbance very easily take place to fall to the bed condition, old patient is the high incidence crowd who falls to the bed equally, has reported to show that about 2.4 thousandth old inpatient appears falling to the bed, and the elder that loses intelligence disability, unconsciousness, restlessness, epileptic seizure, involuntary ability and incoordination treatment is more easily taken place to fall to the bed incident, and falls to the bed incidence and the old age increase and be positive correlation. Serious complications are easy to occur after the patient falls down to the bed, and complications such as brain trauma or organism injury and the like are sometimes caused, even death is caused, and the problems such as medical disputes and the like can be caused. The falling event can also increase the economic burden of the family of the patient, prevent the fall of the inpatient, reduce the occurrence rate of injury of grade 2 or more caused by the fall, reduce the medical cost of the patient and shorten the inpatient time.

The hospitalization safety of children is always a focus of attention, and according to statistics, the reasons for the 3 first positions of the children's accidental injuries are accidental falling injuries, traffic accidents and accidental falling respectively, in the event of falling down to the bed injuries, the head injuries are the most 70.0%, and researches show that 81.6% of the hospitalized children fall down to the bed, and the falling down of the children to the bed is 91.5% due to the fact that the bed rail is not pulled up or is too low; bed guard rails are a common tool for preventing patients from falling down to the bed in hospitals. Because most of clinically used bed guardrails are short, and guardrails at the head and the tail of the bed are missing, patients can easily fall down from the gap of the head or the tail of the bed. Because most of pediatric use of many comprehensive hospitals without accompanying management is adult sickbeds, gaps among guardrails of many adult sickbeds are 35cm in width and 42cm in height, head circumference of children aged 2 are 48cm, chest circumference is 49cm, body mass is 12-13 kg, head circumference and chest circumference diameters of children aged 2 are smaller than the gaps of the guardrails, and danger of falling from the gaps of the guardrails is felt slightly carelessly.

However, if the higher child bed guard rail is used for special people such as hemiplegia, tumor, consciousness disturbance, children and the like, the nursing of patients by family members and medical staff is inconvenient. Therefore, the guardrail structure with adjustable height appears, when a user uses the nursing bed, the guardrail structure rises to prevent the user from falling from the nursing bed, and when the user gets on or off the bed or nursing personnel performs nursing, the guardrail structure is reduced, and the use is more convenient.

Although the existing guardrail has a lifting function, the following defects also exist: the guardrail has no locking structure, and the guardrail is supported through the lifting driving piece, and the bearing effect of guardrail is poor, and the reliability is lower, if use high-power lifting driving piece then manufacturing cost is high.
