Medical care floor and method of use

The invention relates to a medical care floor, in particular to a medical care floor which uses floor pressure sensing technology to achieve fall or gait abnormality detection and remote monitoring by wireless transmission technology.

According to research, changes in daily behavior patterns may represent early signs of potential disease or physiological deterioration. Disease and physiological deterioration can lead to changes in behavioral levels at both the psychological and physiological levels, and as the age increases, the body's resistance and physiology become weaker, and the chance of contracting the disease is greatly enhanced.

As a result of the rapid industrialization and urbanization of society, the family structure has undergone tremendous changes, resulting in more and more elderly people living alone due to voluntary or involuntary factors. At present, there are 1,045 long-term care and security institutions for the elderly under the Ministry of the Interior and the counties and municipalities. The number of people entering the household is 42,2, accounting for 1.65% of the elderly population; in other words, 98.35% of the elderly are close to 2.56 million. Living in a home style such as a child, spouse or solitary living. In this regard, the latest investigation of the "Investigate of the Elderly" by the Ministry of the Interior was carried out in the second half of 1998. The sample of the elderly population at the end of June 1998 was sampled, and 5520 valid samples were actually completed. The survey results show that the family type is mainly three generations of families. It accounted for 37.9%, followed by the second-generation family, accounting for 29.8%, while the elderly living alone stood at 9.2%, the residential security or maintenance institutions accounted for 2.8%, and the number of people living alone was about 230,000, and the number of people per year increased.

The rapid increase in the elderly population has led to many important issues. For example, Parkinsons' disease (PD) is a progressive neurological disease associated with aging. Almost all patients with Parkinson's disease are affected by walking disorders. Slowness of movement, freezing of gait (FOG), shuffling steps, gait inconsistency, lack of balance, and reduced rotation of the trunk cause an increase in the risk of falling. At present, the research on fall detection is mainly divided into two types: portable and non-portable. The portable type is usually worn on the user or placed in the user's carry-on items, and the body posture change is used as a basis for judgment, for example. Detection methods such as inertial accelerometers and gyroscopes, application smart phones, multi-point RFID radio frequency identification technology fall, such detection methods are usually small, convenient to use and low in cost, but it also has to forget to carry and wear Inconvenience and disadvantages such as environmental restrictions (toilet, bathroom).

The other fixed type mainly uses the device to be in the environment in a fixed or embedded manner to judge the action or state of the subject. For example, an infrared sensor is arranged at the bedside to detect the situation in which the subject is going to bed; or a pressure sensor is placed on the bed to detect the number and movement of the subject to sleep and turn over. Although this type of detection can improve the shortcomings of the portable type, the installation is cumbersome, and the monitoring range is limited by the area where the sensor is installed, and the overall system structure is large and the cost is high. Furthermore, the setting of the fixed sensing device is liable to cause a dead space in the space, and it is possible that the situation of the subject to be tested cannot be detected. At present, in the research of anti-theft detection, most of the video and network monitoring systems combined with their applications are necessary equipment for home preservation. For example, the use of VoIP and security video surveillance systems, the monitoring mechanism built by the application of network cameras and network dynamic monitoring, etc., but the disadvantage is that the installation of cameras and network equipment will also cause the use of The issue of privacy.
