Abstract
Description
Technical Field
[0001] This invention relates to the technical field of medical devices, specifically to an intelligent anti-slip tube body restraint garment based on pressure sensing and adaptive adjustment. Background Technology
[0002] In clinical nursing, physical restraints are often used to prevent patients who are confused, agitated, or in the recovery phase from anesthesia from unconsciously removing life support tubes (such as endotracheal tubes, gastric tubes, and central venous catheters). Traditional restraint methods often involve using cotton restraint straps to fix the patient's wrists or ankles to the edge of the bed.
[0003] However, existing technologies have the following obvious drawbacks: 1. Physiological and psychological harm: The restraint straps directly bind the joints, which can easily lead to skin lacerations, poor blood circulation, and nerve damage. They also give patients a strong sense of "imprisonment," causing anxiety and resistance, which in turn increases the risk of extubation.
[0004] 2. Restraint failure: Traditional fixation methods are simple, and patients can loosen the restraints by repeatedly rubbing or twisting them, or even use their other hand to remove the tubes, resulting in poor restraint reliability.
[0005] 3. Lack of early warning: Nursing staff cannot keep track of patients' restraint status and agitation levels in real time, and can only discover problems during rounds, making it impossible to intervene in advance. Summary of the Invention
[0006] The purpose of this invention is to provide an intelligent anti-slip tube body restraint garment based on pressure sensing and adaptive adjustment to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, the present invention provides the following technical solution: an intelligent anti-slip body restraint garment based on pressure sensing and adaptive adjustment, comprising a restraint garment body, restraint flaps installed on both sides of the restraint garment body, an inner groove opened in the restraint flap, a restraint strap installed in the inner groove, the end of the restraint strap away from the restraint flap wrapped around the arm, a locking buckle installed on the side of the restraint strap away from the restraint flap, and a pulling member installed on the side of the restraint flap away from the restraint garment body, the pulling member being connected to the restraint strap.
[0008] Furthermore, the pulling component includes a restraining ring strap, which is installed on the side of the restraint flap away from the restraint garment body. The restraining ring strap is looped around the thigh. An inner groove is opened inside the restraint flap, and a movable component is installed in the inner groove. One end of the movable component is connected to the restraint strap, and a connecting pull strap is installed at the end of the movable component away from the restraint strap. The end of the connecting pull strap away from the movable component is connected to the restraint strap.
[0009] Furthermore, the movable component includes multiple movable rings, which are installed in the inner groove. A movable belt is slidably connected inside the movable ring, and both ends of the movable belt are connected to a constraint belt and a connecting pull belt, respectively.
[0010] Furthermore, a pressure sensor is installed on the restraint flap, and the pressure sensor is in contact with the connecting strap. A microprocessor module is installed on the outside of the restraint garment body. The microprocessor module is used to receive and process the signal from the pressure sensor. The microprocessor module is connected to a wireless communication module, and the wireless communication module is connected to the nurse station host. An audible and visual alarm is installed on the outside of the restraint garment body, and the audible and visual alarm is connected to the microprocessor module.
[0011] Furthermore, the restraint garment body has male and female hook and loop fasteners respectively installed on both sides of the front, and the male and female hook and loop fasteners are attached to each other.
[0012] Furthermore, an adjustable buckle is installed on the shoulder area of the front of the restraint garment, and a fixing strap is installed on the back of the restraint garment, the fixing strap being connected to the adjustable buckle.
[0013] Furthermore, the restraint suit body has a pipe opening on the front, and a life tube is inserted into the pipe opening. Multiple restraint rings are installed on the front of the restraint suit body, and the life tube is inserted into the restraint rings.
[0014] Furthermore, the restraint garment has a storage pocket installed inside, and the restraint flaps are disposed inside the storage pocket.
[0015] Furthermore, a magnetic ring is installed inside the restraint garment, and a magnetic buckle is installed on the side of the restraint flap facing the restraint garment body. The magnetic buckle and the magnetic ring are magnetically attracted to each other.
[0016] Furthermore, the restraint garment body has a breathable mesh opening on the back.
[0017] This invention provides an intelligent anti-slip tube body restraint garment based on pressure sensing and adaptive adjustment, which has the following beneficial effects: 1. This invention involves installing multiple movable rings within the restraint flap, and then installing a limiting strap on the side of the restraint flap away from the restraint garment body. The limiting strap is then placed around the thigh, and a movable strap is slidably connected within the movable rings. The two ends of the movable strap are connected to the restraint strap and the connecting pull strap, respectively. When the restraint strap is wrapped around the patient's arm via the locking buckle, the limiting strap and the restraint flap simultaneously pull on the restraint strap, reducing the probability of the patient unintentionally pulling out the tube. At the same time, the movable strap can move freely within the movable rings, thereby reducing the restraint on the patient's arm and increasing patient comfort. Furthermore, the pulling ring pulls on the restraint garment body through the restraint flap, thereby reducing the probability of the restraint garment body being moved.
[0018] 2. This invention installs a pressure sensor on the restraint flap. When the patient's arm moves involuntarily, the moving strap will not come into contact with the connecting strap, thus preventing the pressure sensor from triggering an alarm. When the patient removes the tube involuntarily, the moving strap and the connecting strap are aligned, and the patient's arm movement causes the connecting strap to come into contact with the pressure sensor and trigger an alarm, thereby increasing the accuracy of the pressure sensor triggering the alarm.

[0021] Please see Figures 1 to 6This invention provides a technical solution: an intelligent anti-slip body restraint garment based on pressure sensing and adaptive adjustment, comprising a restraint garment body 1, wherein the restraint garment body 1 has a breathable mesh 12 on the back to increase the breathability of the restraint garment body 1, restraint flaps 23 are installed on both sides inside the restraint garment body 1, and a storage pocket 5 is installed inside the restraint garment body 1, in which the restraint flaps 23 are placed to store the restraint flaps 23, preventing the restraint flaps 23 from falling off, and preventing the restraint flaps 23 from contacting the patient's body when removed from the restraint garment body, thereby reducing the damage to the patient, a magnetic ring 13 is installed on the inside of the restraint garment body 1, and a magnetic buckle 21 is installed on the side of the restraint flaps 23 facing the restraint garment body 1, the magnetic buckle 21 and the magnetic ring 13 are magnetically attracted, and the cooperation of the magnetic buckle 21 and the magnetic ring 13 prevents the restraint flaps 23 from falling out of the storage pocket 5 during daily transportation.
[0022] The restraint flap 23 has an inner groove 22, and a restraint strap 14 is installed in the inner groove 22. A locking buckle 15 is installed on the side of the restraint strap 14 away from the restraint flap 23. The end of the restraint strap 14 away from the restraint flap 23 is wrapped around the arm. After the restraint strap 14 is wrapped, the locking buckle 15 is used to restrict it and prevent the restraint strap 14 from falling off the arm. A restraint ring 17 is installed on the side of the restraint flap 23 away from the restraint garment body 1. The restraint ring 17 is put on the thigh and the thigh is used to restrict the position of the restraint ring 17, thereby pulling and restricting the restraint flap 23 and preventing the restraint flap 23 from moving at will. Multiple movable rings 18 are installed in the inner groove 22. A movable belt 20 is slidably connected in the movable rings 18. The two ends of the movable belt 20 are connected to the restraint strap 14 and the connecting pull strap 16, respectively. The movable belt 20, the restraint strap 14 and the connecting pull strap 16 form a triangular area. The movable belt 20 can slide in the multiple movable rings 18 as the patient's arm moves.
[0023] By installing multiple movable rings 18 inside the restraint flap 23, and then installing a limiting strap 17 on the side of the restraint flap 23 away from the restraint garment body 1, and placing the limiting strap 17 on the thigh, and then sliding a movable belt 20 inside the movable ring 18, with both ends of the movable belt 20 connected to the restraint strap 14 and the connecting pull strap 16 respectively, when the restraint strap 14 is wrapped around the patient's arm through the locking buckle 15, the limiting strap 17 and the restraint flap 23 simultaneously pull on the restraint strap 14, reducing the probability of the patient unconsciously pulling out the tube. At the same time, the movable belt 20 can move freely within the movable ring 18, thereby reducing the restraint on the patient's arm and increasing the patient's comfort. Furthermore, the pull ring pulls the restraint garment body 1 through the restraint flap 23, thereby reducing the probability of the restraint garment body 1 being moved.
[0024] A pressure sensor 19 is installed on the restraint flap 23. The pressure sensor 19 is in contact with the indirect connection strap 16. A microprocessor module 3 is installed on the outside of the restraint garment body 1. The microprocessor module 3 is used to receive and process the signal from the pressure sensor 19. The microprocessor module 3 is connected to the wireless communication module. The wireless communication module is connected to the nurse station host. An audible and visual alarm 2 is installed on the outside of the restraint garment body 1. The audible and visual alarm 2 is connected to the microprocessor module 3. The audible and visual alarm 2 serves as a reminder. When the patient exhibits unconscious extubation behavior, it alerts the surrounding nurses and doctors. At the same time, the microprocessor module 3 transmits the signal to the nurse station host through the communication module. The nurse station host provides real-time monitoring.
[0025] By installing a pressure sensor 19 on the restraint flap 23, when the patient's arm moves unconsciously, the moving strap 20 will not contact the connecting strap 16, thus preventing the pressure sensor 19 from triggering an alarm. When the patient unconsciously pulls out the tube, the moving strap 20 and the connecting strap 16 are aligned, and the patient's arm moving strap 20 and the connecting strap 16 contact the pressure sensor 19 and trigger an alarm, thereby increasing the accuracy of the pressure sensor 19 triggering the alarm.
[0026] The restraint garment body 1 has a male Velcro face 6 and a female Velcro face 4 installed on both sides of the front. The male Velcro face 6 and the female Velcro face 4 fit together, making it easier for the patient to wear the restraint garment body 1. An adjustable buckle 8 is installed at the shoulder position on the front of the restraint garment body 1, and a fixing strap 9 is installed on the back of the restraint garment body 1. The fixing strap 9 is connected to the adjustable buckle 8. The fixing strap 9 and the adjustable buckle 8 work together to fix the restraint garment body 1 to the patient's body, thereby locking the position of the restraint garment body 1 on the patient's body.
[0027] The restraint suit body 1 has a pipe opening 10 on the front, and a life pipe 11 is inserted into the pipe opening 10. Multiple restraint rings 7 are installed on the front of the restraint suit body 1. The life pipe 11 is inserted into the restraint rings 7. The restraint rings 7 are used to restrict the position of the life pipe 11 and reduce the probability of the life pipe 11 shaking.
[0028] In summary, this intelligent anti-slip body restraint garment based on pressure sensing and adaptive adjustment is used by first putting the restraint garment body 1 on the patient, then using the cooperation of the male side 6 and the female side 4 of the Velcro to fix the restraint garment body 1 to the patient's waist, using the cooperation of the adjustable buckle 8 and the fixing strap 9 to fix the restraint garment body 1 to the patient's shoulders, and taking the restraint flap 23 out of the storage pocket 5 and putting the restraint strap 17 on the patient's thigh. After the restraint garment body 1 is fixed, the life tube 11 is inserted from the tube opening 10.
[0029] Then, using the locking buckle 15, the restraint strap 14 is wrapped around the patient's wrist. When the patient's arm moves unconsciously, if the patient's arm is not moving towards the life tube 11, but is just a normal unconscious movement, the moving strap 20 and the connecting pull strap 16 are not aligned, so they cannot contact the pressure sensor 19 and trigger the alarm. Since the moving strap 20 slides within the moving ring 18, when the patient's arm moves unconsciously, the moving strap 20 can move within the moving ring 18, thereby increasing the range of motion of the restraint strap 14 and the connecting pull strap 16, making it easier for the patient's arm to move freely without getting close to the chest, increasing the range of motion of the patient's arm, and increasing the patient's comfort.
[0030] When a patient's arm moves unconsciously toward the lifeline 11 or attempts to remove the tube, the fixed lengths of the moving strap 20, restraint strap 14, and connecting strap 16 prevent the arm from moving beyond its fixed range of motion. When the patient needs to move their arm to their chest, the connecting strap 16 moves closer to their chest. As the connecting strap 16 moves closer to their chest, it aligns with the restraint flap 23 and comes into contact with the pressure sensor 19 mounted on the restraint flap 23. This causes the restraint pressure sensor 19 to detect the patient's unconscious removal of the tube and send a signal to the microprocessor module 3. Upon receiving the signal, the microprocessor module 3 sends a signal to the audible and visual alarm 2, which then sounds an alarm to alert nearby doctors and nurses.
