Abstract

In a hospital bed with guardrails and a hospital bed control method, two guardrails are respectively arranged on both sides of the main body of the hospital bed; when the guardrails are raised, the raised guardrails partially or completely protect the edge of the main body of the hospital bed; when the guardrails are lowered, the edge of the main body of the hospital bed is open; a guardrail control switch independently controls the raising and lowering of a guardrail; the position of the guardrail control switch and the position of the guardrail controlled by the guardrail control switch are respectively arranged on both sides of the longitudinal center section or longitudinal center line of the main body of the hospital bed, or the position of the guardrail control switch is arranged on the opposite side of the guardrail controlled by it. Non-same-side control guardrails avoid the situation that the patient will approach the edge of the bed when the same-side control is used, thereby avoiding the situation that the patient accidentally falls from the bed; it takes into account the patient's autonomous control intention and avoids the accidental fall when the same-side control is used.

Description

Sickbed with guardrails and sickbed control method

Technical Field

The invention belongs to the technical field of medical sickbeds or household nursing beds. In particular to a sickbed or nursing bed with guardrails.

Background

The sickbed has a narrow width because of the limited space for placing the sickbed in the ward. In order to prevent patients from accidentally falling from a sickbed, lifting guardrails are usually arranged on two sides of the sickbed, and are lifted when the patients need to be protected, and are put down when the patients get on or off the sickbed.

In the prior art, a control switch for controlling the lifting of the guardrail is arranged on the guardrail or arranged at the bottom or the side of the bed on the same side of the guardrail.

For the control switch arranged at the bedside, when the patient himself or herself controls the control switch at the same side, the patient is generally required to be relatively close to the guardrail. When a patient moves from the center of a sickbed to the position close to the bedside, sometimes, the body often contacts with the guardrail or is very close to the guardrail, after the control switch is controlled, the guardrail is put down, the gravity center is easily lost carelessly and falls from the bedside, and especially for the elderly, the patient or the disabled, the body or the spirit is in a uncomfortable pathological state, and the falling is more easy to occur under the condition that the body is controlled to be moved very conveniently or very flexibly.

In order to avoid direct control of patients on the sickbed, the guardrail switch of some sickbeds in the prior art is arranged under the sickbed. Such design is intended to facilitate the control of the guardrail state by the attendant, but does not take into account the patient's willingness to autonomously control the guardrail state. A patient, especially a patient who has a certain mobility of himself, even for elderly, patients or disabled persons, is often more willing to control the status of the guard rail by himself, in case he is at his own right, than to ask for help from an outsider, especially in case the caretaker is at rest in the middle of the night, which request may give the patient an unnecessary mood. However, for the control switch arranged at the bottom of the bed, namely when the control switch is arranged below the bed main body, when a patient goes to operate the control switch, the upper part of the patient needs to cross the guard rail, the patient can cross the edge of the bed by carelessness, and accidents of falling from the sickbed can occur more easily. The design described above therefore tends to increase the probability of a fall accident.

There is a great need for a hospital or care bed that allows the patient to control the condition of the guard rail autonomously while preventing the patient from falling.
