Description

Technical Field

[0001] The invention relates to a restraint belt, in particular to a multifunctional induction alarm restraint belt. Background Art

[0002] In clinical practice, restraint belts are often used for patients with impaired consciousness or who are irritable and uncooperative. The restraint belts currently used have a simple structure, with wrist pads wrapped around the patient's limbs and Velcro wrapped around the pads to fix the pads. When patients experience large mood swings, they will pull on the restraint belts in various ways. If the restraints are slightly loosened, the patients will break free from the restraints. Some patients will unplug their own tubes after breaking free from the restraint belts, or even leave their beds and cause accidents. In mild cases, it will increase the risk of pain and infection for patients, and in severe cases, it may endanger the patient's life.

[0003] The existing restraints use Velcro to fix the soft pads. When the patient pulls the restraint agitatedly, the restraint wristband is easily loosened. In addition, the restraints do not have an alarm device. When the patient breaks free from the restraint at night, the nursing staff cannot be informed in time to stop the patient. Summary of the invention

[0004] The purpose of the present invention is to overcome the above-mentioned defects of the prior art and provide a multifunctional induction alarm restraint belt, which uses optical sensing technology and an alarm device to enable medical staff to promptly detect when the restraint ring is broken free, thereby improving the effectiveness of the use of the restraint ring.

[0005] The present invention provides a multifunctional induction alarm restraint belt, comprising: a restraint ring and an induction alarm module, a knob, and a strap arranged on the restraint ring; the restraint ring is wrapped around the patient's arm, and the strap is connected to the bed to restrict the patient's activities;

[0006] The sensing alarm module is provided with an optical sensor. The blood flow rate and volume will change, thereby affecting the amount of reflected light from the skin tissue. When the optical sensor receives the change in reflected light, it indicates that the restraint is worn normally. On the contrary, when the optical sensor does not receive the change in reflected light, it indicates that the restraint has been broken free. The optical sensor is connected to the signal processor, and the signal processor is connected to the alarm light. The optical sensor transmits the signal to the signal processor, which transmits the signal to the alarm light after analysis.

[0007] Furthermore, the restraint ring is a cotton fabric restraint ring, which is soft to the touch, easy to wash and maintain.

[0008] Furthermore, an inflatable airbag is arranged inside the restraint ring to provide a targeted compression and hemostasis effect. When the airbag on the restraint belt is inflated, it can be used for compression and hemostasis.

[0009] Furthermore, a gear is provided on the knob, and the gear is connected to the wire rope. When the knob is rotated clockwise, the wire rope is tightened, and when the knob is rotated counterclockwise, the wire rope is loosened. The knob can adjust the tightness of the constraint ring.

[0010] Furthermore, the knob is pressed down to lock and lifted up to unlock.

[0011] Furthermore, the induction alarm module is provided with a buzzer.

[0012] Furthermore, the buzzer is a piezoelectric buzzer.

[0013] Furthermore, when the restraint is normal, the warning light flashes green; when the restraint is abnormal, the warning light flashes red.

[0014] Furthermore, the optical sensor is a photoplethysmograph (PPG).

[0015] Furthermore, the optical sensor can emit green light or red light, which is reflected back to the optical sensor through skin tissue; and can detect changes in the intensity of the reflected or transmitted light, thereby reflecting changes in blood volume.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] (1) Intelligence improves the effectiveness of the restraint ring: This device uses optical sensing technology and an alarm device. Through optical sensing technology, the optical sensor will emit green or red light, which will be reflected back to the sensor through the skin tissue. When the heart beats, the blood flow rate and volume will change, which will in turn affect the amount of light reflected by the skin tissue. When the sensor receives the change in reflected light, it means that the restraint is worn normally; conversely, when the sensor does not receive the change in reflected light, it means that the restraint has been broken free. When the sensor does not receive the change in reflected light, it is transmitted to the sound and light alarm system through the connecting wire, so that medical staff can promptly discover that the restraint ring has been broken free, thereby improving the effectiveness of the restraint ring.

[0018] (2) A wide range of restraint uses: In addition to being used as a restraint, when the airbag on the restraint belt is inflated, it can also be used for compression and hemostasis.

[0019] (3) Restraint safety: The traditional restraint belt buckle Velcro method is abandoned and improved into a knob. It is connected to the wire rope through a gear. When the knob is turned clockwise, the wire rope is tightened, and the tightness of the restraint ring is fixed by pressing the button.

[0020] (4) Easy to clean: The induction alarm device can be removed, and the restraint ring is made of cotton fabric, which is soft to the touch and easy to wash and maintain. BRIEF DESCRIPTION OF THE DRAWINGS
