Description

Technical Field

[0001] The utility model relates to the field of hospital beds, in particular to an alarm bed based on an anti-hanging device for bedridden patients. Background Art

[0002] Mental patients commit suicide due to the influence of morbid thinking. Therefore, it is very necessary to design an alarm bed with an anti-hanging device for bedridden patients. Utility Model Content

[0003] In order to overcome the above-mentioned technical problems, the utility model aims to provide an alarm bed based on an anti-hanging device for bedridden patients, which senses the gravity above it through a gravity sensor, and transmits an electrical signal from the gravity sensor to a microprocessor. The microprocessor is used to receive and process the electrical signal of the gravity sensor, and control the operation of the alarm and the motor at the same time. When a hanging behavior is detected, an alarm is sounded through the alarm, so that by changing the guardrail structure at the head and foot of the bed, the gravity borne by the guardrail is monitored through the gravity sensor, and it is determined whether the mentally ill patient has hanged himself, and an alarm is sounded to promptly remind the guardian, and the motor drives the screw rod to rotate, drives the guardrail to move down, lowers the height of the guardrail, and reduces the force on the neck of the patient who hangs himself on the guardrail, thereby automatically taking rescue measures for the hanging patient to avoid the guardian's inability to respond in time.

[0004] The purpose of the utility model can be achieved through the following technical solutions:

[0005] A bed with an anti-hanging device alarm for bedridden patients, comprising a bed board, both ends of which are fixedly provided with guardrail assemblies, the guardrail assemblies comprising a hollow support rod, a reinforcement rod, a guardrail and a tightening knob, a lifting assembly movably arranged inside the hollow support rod, the lifting assembly comprising a base, a gravity sensor, a fixing seat, a motor and a screw rod, and a control box is fixedly installed on the lower surface of the bed board.

[0006] Furthermore, the four hollow support rods are respectively fixedly installed at the four corners of the outer surface of the bed board, and the lower ends of the guardrails are respectively movably arranged inside the two hollow support rods and are slidably connected to the hollow support rods.

[0007] Furthermore, a slide groove is provided at the upper end of the outer surface of the hollow support rod, a threaded hole is provided at the outer surface of the hollow support rod, a limiting hole is provided at the lower end of the outer surface of the guardrail, and the reinforcement rod is fixedly connected between the two hollow support rods.

[0008] Furthermore, the fastening knob passes through the threaded hole and is movably connected with the limiting hole, and the fastening knob is screwed together with the threaded hole, and a threaded groove is provided on the lower end surface of the guardrail.

[0009] Furthermore, the screw rod is movably arranged inside the thread groove and is screwed together with the thread groove, and the lower end of the screw rod is fixedly connected to the output end of the motor.

[0010] Furthermore, the gravity sensor is fixedly installed on the upper surface of the base, the fixing seat is fixedly installed on the upper surface of the gravity sensor, and the motor is fixedly installed on the inner side of the fixing seat.

[0011] Furthermore, a microprocessor and an alarm are fixedly arranged inside the control box, and the microprocessor is electrically connected to the alarm, the gravity sensor and the motor respectively.

[0012] Beneficial effects of the utility model:

[0013] 1. By screwing the fastening knob into the threaded hole, the position of the guardrail is limited so that it can be used by patients who do not have a tendency to hang themselves. When used by patients with a tendency to hang themselves, the fastening knob is removed so that the guardrail can be moved up and down.

[0014] 2. The gravity sensor senses the gravity above it. When the guardrail is subjected to a large gravity, the gravity sensor transmits an electrical signal to the microprocessor. The microprocessor is used to receive and process the electrical signal of the gravity sensor, and control the operation of the alarm and the motor at the same time. When a suicide attempt is detected, an alarm is sounded through the alarm. By changing the guardrail structure at the head and foot of the bed, the gravity sensor monitors the gravity borne by the guardrail, determines whether the mentally ill patient is in a suicide attempt, and sounds an alarm to promptly remind the guardian.

[0015] 3. The motor runs, driving the screw rod to rotate, and through the screw rod and the threaded groove, the guardrail is driven down to lower the height of the guardrail, thereby reducing the force on the neck of the patient who hangs himself on the guardrail, thereby automatically taking rescue measures for the patient who hangs himself to avoid the guardian's inability to respond in time.
