Description

Technical Field

[0001] This utility model relates to the field of medical and nursing device technology, specifically a monitoring device for elderly patients getting out of bed. Background Technology

[0002] With the increasing aging of the population, the medical care needs of elderly patients are growing. Because elderly patients often experience mobility issues, decreased balance, and cognitive impairment, their unplanned attempts to get up or leave the bed during hospitalization can lead to falls and other accidents, seriously affecting their recovery process and even increasing medical risks. Given these unique characteristics of elderly patients, monitoring their unplanned getting up and leaving the bed is of significant practical importance. On the one hand, it allows for timely understanding of patients' needs to get out of bed, enabling caregivers and medical staff to respond quickly and provide necessary assistance; on the other hand, real-time monitoring of patients' getting up and leaving the bed allows for the timely detection of abnormalities and the implementation of appropriate measures, significantly reducing the incidence of falls and other accidents.

[0003] Currently, monitoring elderly patients' exit from bed in hospital wards primarily relies on manual care, i.e., nurses or caregivers making regular rounds or responding to requests through a patient call system. However, this approach has several limitations. Manual care cannot provide continuous real-time monitoring; patients may get out of bed unattended (especially at night), leading to accidents. Caregivers require significant time and effort, resulting in heavy workloads and a high risk of oversights. Some medical institutions are currently experimenting with mattress pressure sensors or camera monitoring for exit detection, but existing solutions are easily affected by patient movements such as turning over, leading to high false alarm rates. Furthermore, camera monitoring raises privacy concerns and is susceptible to interference from ambient light and obstructions.

[0004] Therefore, there is an urgent need for a timely, efficient, and false alarm-reducing monitoring solution for getting out of bed, so as to detect elderly patients' intentions or behaviors to get out of bed in real time, and promptly remind caregivers to intervene, thereby reducing the risk of accidents and alleviating the burden on medical staff. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology mentioned above by providing a monitoring device for elderly patients getting out of bed. By combining two sensing methods, when a change in body pressure signal is detected and a movement is detected, it can determine that the patient has gotten out of bed and promptly notify the nurse or caregiver. This device can sensitively detect movement while reducing the probability of misjudgment.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: A device for monitoring elderly patients getting out of bed includes an optical monitoring component placed on the bed rail, a pressure detection component placed on the bed surface, and a network module. The optical monitoring component includes an infrared sensing mechanism, a first mounting base, and a second mounting base. The first and second mounting bases are detachably mounted on the left and right side bed rails, respectively. The infrared sensing mechanism includes an infrared sensor and a reflector. The infrared sensor is mounted on the first mounting base, and the reflector is mounted on the second mounting base. The probe of the infrared sensor faces the reflector, and the infrared light from the sensor spans across the bed surface. The pressure detection component includes a pad and a thin-film pressure sensor, which is laid flat on the pad. Both the infrared sensor and the thin-film pressure sensor are connected to the network module, which is connected to a nursing station system or a smart terminal device.

[0007] Preferably, both the first mounting base and the second mounting base include a snap-fit ​​seat, the snap-fit ​​seat has a snap-fit ​​groove with an opening facing downwards, the snap-fit ​​groove is for the bed rail to be fitted into, and a locking element is provided on the side of the snap-fit ​​seat for locking the snap-fit ​​seat to the bed rail.

[0008] Preferably, the first mounting base includes a housing, which is disposed above the fastening seat, and the infrared sensor and network module are both integrated into the housing.

[0009] Preferably, the housing has a built-in control circuit board, and the outside of the housing has an on / off button and an indicator light. The infrared sensor, the thin-film pressure sensor, the on / off button and the indicator light are all electrically connected to the control circuit board. The on / off button controls the opening and closing of the infrared sensor and the thin-film pressure sensor, and the indicator light indicates the operating status of the infrared sensor and the thin-film pressure sensor through light.

[0010] Preferably, the first mounting base is further provided with a field alarm mechanism, which includes one or a combination of a light alarm, a voice alarm, and a prompt sound alarm. The field alarm mechanism is connected to an infrared sensor and a thin-film pressure sensor circuit.

[0011] Preferably, the on-site alarm mechanism includes a retractable light pole and a light alarm. The outer wall of the housing is provided with a vertically arranged light pole storage slot, and the top of the light pole storage slot is provided with a rotating shaft structure. The tail end of the retractable light pole is connected to the rotating shaft structure, and the light alarm is located at the head end of the retractable light pole. The retractable light pole can be flipped upward to an open state that extends vertically upward, and the retractable light pole can be flipped downward to a retracted state that is embedded in the light pole storage slot.

[0012] Preferably, the locking component includes a locking knob, which includes a locking rod and a manual knob. The locking rod is threadedly connected to the snap-fit ​​seat and extends from the outside of the snap-fit ​​seat into the snap groove. The manual knob is fixedly connected to the outer end of the locking rod. An anti-slip pad is provided on the inner wall of the snap groove opposite to the locking knob.

[0013] Compared with existing technologies, the elderly patient getting out of bed monitoring device using the above-mentioned technical solution has the following beneficial effects: A thin-film pressure sensor, which can be placed on the bed surface, can detect pressure changes when a patient gets up. Combined with an infrared sensor for transverse detection across the bed surface, the signals from both sensors are combined and calculated to more accurately determine whether a patient has gotten out of bed, avoiding misjudgments caused by simple turning over or other physical movements. By connecting to the nursing station or a smart terminal device (such as a mobile phone), nurses or caregivers can be notified promptly, enabling timely assistance or intervention for the patient and effectively preventing accidents caused by unplanned getting up or leaving the bed.

[0014] The optical monitoring components are detachably mounted on the bed rails and can be easily adjusted to a suitable position, providing greater flexibility in use.

[0015] The specially designed on-site alarm mechanism can be opened in monitoring mode, allowing the light alarm to extend vertically above the bed rail, making it convenient for nurses and caregivers to observe and quickly identify patients who have gotten out of bed. In non-monitoring mode, the light alarm can be flipped down for storage, reducing obstruction to the movement of patients and bedside personnel, and also reducing the probability of the light alarm being damaged by accident.

The manual knob 312 is fixedly connected to the outer end of the locking rod 313. The inner wall of the fastening groove 311 opposite to the locking knob is provided with an anti-slip pad 314.

[0024] The infrared sensing mechanism includes an infrared sensor 5 and a reflector 6. The infrared sensor 5 is mounted on a first mounting base 31, and the reflector 6 is mounted on a second mounting base 32. The first mounting base 31 includes a housing 315, which is fixedly mounted above a fastening seat 310. The infrared sensor 5 is integrated into the housing 315. The first mounting base 31 includes an additional housing corresponding to the height of the housing 315, which is fixedly mounted above the fastening seat 310. The reflector 6 is located on the inner wall of the additional housing. The probe of the infrared sensor 5 faces the reflector 6, and the optical path of the infrared sensor 5 emitting and receiving infrared light spans across the bed surface 2.

[0025] The pressure detection component 4 includes a pad 40 and a thin-film pressure sensor 41. The thin-film pressure sensor 41 is laid flat on the pad 40, which is placed on the bed surface 2 and located under the patient's buttocks and back.

[0026] The housing 315 houses a control circuit board and a network module. The control circuit board is a programmable control circuit board, and the network module is connected to the control circuit board. The infrared sensor 5 and the thin-film pressure sensor 41 are also connected to the control circuit board.
