Description

Technical Field

[0001] The utility model relates to the technical field of alarms, in particular to a plug-in type alarm for preventing falling out of bed. Background Art

[0002] Falls from bed occur frequently in hospitalized patients with cardiovascular and cerebrovascular diseases. According to relevant statistics, the incidence of falls from bed at night is much higher than that during the day. Most of the time, patients need to urinate or defecate, or move independently when resting at night, and they get out of bed and move around alone without informing their family members. Due to poor lighting, many obstacles, and insufficient self-care ability of patients (weakness, hemiplegia, etc.), they eventually fall from bed, causing injuries such as fractures and subcutaneous hematomas, thereby prolonging the patients' recovery and hospitalization time, and increasing the financial burden on patients.

[0003] In the prior art, the existing plug-in type fall prevention alarm is either too complicated, or imposes too much constraints on patients, and the comfort and economic experience of patients is too poor, or the installation is complicated. Utility Model Content

[0004] The utility model mainly provides a plug-in type bed-fall prevention alarm which is simple to assemble and connect, can be assembled once, and the alarm device can be reused to improve the utilization rate; and the alarm can be triggered in the first time before the patient gets out of bed to notify the patient's family members.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a plug-in type alarm for preventing falling from bed, comprising a strap, Velcro is provided at both ends of the outer wall of the strap, a connecting strap is fixed on the outer wall of the strap, the layers in the connecting strap are fixed by snap fasteners, an insertion rod is fixed on the top of the connecting strap, an alarm body is provided on the outer side of the insertion rod, a slot matching the insertion rod is opened at one end of the alarm body, limiting structures for limiting the insertion rod are provided on both sides of the inner wall of the slot, an infrared transmitter is installed at one end of the slot, an infrared receiver is installed at the other end of the slot, a controller is installed on the inner wall of the slot on one side of the insertion rod, a buzzer is installed on one side of the controller, splints are provided on both sides of one end of the alarm body, and a driving structure for driving the two splints to move toward or oppositely is provided in the alarm body.

[0006] Preferably, the limiting structure includes an inner cavity opened at both ends of the inner wall of the slot, springs are fixed on the inner walls of the two inner cavities, and clamps are fixed at opposite ends of the two springs. The opposite ends of the two clamps pass through the inner cavity and are arranged on both sides of the insertion rod, and slots matching the two clamps are opened at both ends of the outer wall of the insertion rod. When the insertion rod is inserted into the slot opened in the alarm body, the two clamps will shrink into the inner cavity due to their arc-shaped settings and the arc-shaped settings of the insertion ends of the insertion rod. When the slots at both ends of the insertion rod move to the position of the two clamps, the two clamps will enter the two slots due to the thrust of the springs, thereby limiting the insertion rod and preventing the insertion rod from accidentally moving out of the alarm body.

[0007] Preferably, the driving structure includes a bidirectional screw arranged in the alarm body, and movable plates are threadedly connected on both sides of the outer wall of the bidirectional screw, and both ends of the two movable plates are slidably connected to limiting columns, and one end of the two movable plates is fixed with a connecting block, and the ends of the two connecting blocks away from the movable plates penetrate the alarm body and are respectively fixed to the two clamping plates. Through the rotation of the bidirectional screw, the two movable plates move toward each other under the limit of the two limiting columns, thereby driving the two clamping plates connected by the two connecting blocks to move toward each other, so that the alarm body can be clamped and installed on the head of the bed, avoiding the problem of unstable placement or troublesome bolt installation, and is more practical.

[0008] Preferably, limiting blocks are fixed at both ends of the outer wall of the card plate, and limiting grooves matching the limiting blocks are opened at both ends of the inner wall of the inner cavity. Through the setting of the limiting blocks and the limiting grooves, the card plate can be limited to prevent the card plate from moving out of the inner cavity as a whole due to the thrust of the spring.

[0009] Preferably, a connecting column is fixed at one end of the bidirectional screw, and the end of the connecting column away from the bidirectional screw passes through the outer wall of the alarm body and is fixed with a rotating plate. Through the arrangement of the connecting column and the rotating plate, the user can rotate the rotating plate to drive the connecting column to rotate, thereby driving the bidirectional screw to rotate.

[0010] Preferably, the other end of the bidirectional screw is rotatably connected to the alarm body, and both ends of the limit column are fixed to the alarm body. A movable groove matching the connecting block is provided on the outer wall of the alarm body. Through the setting of the movable groove, the two connecting blocks can stably move toward or oppositely to avoid principle errors.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] In the utility model, the strap can be tied to the user's arm through the setting of Velcro. At this time, the insertion rod connected to the connecting strap is inserted into the alarm body to achieve the alarm effect, so that the alarm device can be assembled once and can be reused to improve the utilization rate. When the patient is about to get out of bed, if the amplitude is too large, the insertion rod connected to the connecting strap will be driven to separate from the alarm body. At this time, the infrared light emitted by the infrared transmitter is no longer blocked by the insertion rod, but will be received by the infrared receiver. When the infrared receiver receives the signal, it will be transmitted to the controller through the external circuit, and the buzzer will be controlled by the controller to achieve the effect of triggering the alarm in the first time before the patient gets out of bed. In addition, the device drives the connecting column to rotate by the user, thereby driving the bidirectional screw to rotate, so that the two movable plates move toward each other under the limit of the two limit columns, thereby driving the two clamping plates connected by the two connecting blocks to move toward each other, so that the alarm body can be clamped and installed on the bedside, avoiding the problem of unstable placement or troublesome bolt installation, and the utility model is more practical.
