Description

Anti-falling bed baffle capable of lifting in gravity sensing manner and vital sign monitoring sickbed capable of infrared sensing

Technical Field

The invention belongs to the technical field of sickbeds, and particularly relates to a gravity-sensing lifting anti-falling bed baffle and an infrared-sensing vital sign monitoring sickbed.

Background

With the continuous development and popularization of information technology application, the development of concepts such as telemedicine makes hospitals develop towards intelligence and informatization. In order to improve the service quality and the comprehensive strength of the hospital, the upgrading of software and hardware in the hospital is imperative;

in view of the current hospital bed, there is the unsuitable patient of specification, the bed keeps off tong, can not effectively prevent potential safety hazard and the weak problem of function such as weighing down the bed, prior art has alone to keep off to the bed and improves, for example: 1. only the gap between the tail plate of the bed and the guardrail is filled, but the gap between the guardrails of the adult sickbed is not improved, the gap between the guardrails of the adult sickbed is larger, the gap is still a potential risk factor for children with smaller body sizes, and the children still can slide out of the gap between the guardrails to fall down. 2. The gaps at two sides of the sickbed are filled by utilizing the spongy cushion or the resin baffle, the gaps of the guardrails are effectively filled, but the baffle is large in size, not only occupies a large amount of storage space, but also increases the exposed area, increases the bacterial scattering, and increases difficulty for cleaning, disinfecting and sterilizing of the hospital, so that the hospital feel is not easily controlled. 3. The guard rails are transversely provided with one or more detachable guard rails to separate the guard rail gap, but the steps of installing and detaching the guard rails consume time, and the device is not convenient and simple. Because the existence of the guard rail prevents the guardrail of the sickbed from being normally placed, great inconvenience is brought to the daily operation and use of medical care personnel and family members. And it is worth noting that the improvement on the bed bumper is mostly that the patient cannot independently use the bed bumper, and the bed bumper saves labor and time. The prior art lacks improvement on prediction and warning of falling-off risk, and rarely carries out integral optimization improvement aiming at the sickbed, and does not fully excavate other functions of the sickbed.

Due to the weak consciousness and the natural mobility of the crisis of children, the influence of chronic diseases and medicines on some old patients and the like, the falling-off event is very easy to occur when the accompanying family members are busy and careless and cannot pay attention to the condition of the patients in the hospital bed all the time. At present, the falling bed in the hospital belongs to one of the frequently-occurring adverse events. The existing sickbed barrier is only suitable for patients who can move independently or nursing families of bedridden patients, and the sickbed barrier cannot automatically identify and evaluate falling risk factors to adjust the barrier in time to protect the patients. The emergence of falling the bed not only can aggravate patient's the state of an illness, increases its painful of being in hospital and delays normal treatment process even, also can increase medical care risk simultaneously, thereby is unfavorable for medical personnel to ensure the safety of infant patient and reduces the satisfaction of nursing. Secondly, vital signs such as body temperature, pulse rate, heart rate, breathing of the patient during the period of being in hospital often need nurse to pay close attention to, but because nurse's work is busy and can only look over regularly, can't realize real-time dynamic monitoring and timely analysis, feedback monitoring result, often can cause can not in time notice patient's results such as new change on the course of illness.
