Embodiment 1

[0032] A method for detecting a prone position of a piezoelectric sensor, which cooperates with a pressure sensor group arranged on a bed board or other equipment for a user to maintain a prone position. The pressure sensor group includes a single set of head pressure detection area, waist pressure detection area, and back pressure detection area, shoulder pressure detection area, arm pressure detection area, hip pressure detection area, thigh pressure detection area, calf pressure detection area set in pairs Ankle pressure detection area. The relative positions of head pressure detection area, back pressure detection area, waist pressure detection area, shoulder pressure detection area, arm pressure detection area, hip pressure detection area, thigh pressure detection area, calf and ankle pressure detection area and the user's head The relative positions of the pressure detection area on the back, waist, shoulders, arms, buttocks, thighs, calves and ankles are respectively co...

Embodiment 2

[0041] A nursing device applying the lying posture detection method of the piezoelectric sensor as described in Embodiment 1, specifically a home care bed; the home care bed includes a bed structure, a wheelchair structure, an LCD screen, a single-chip microcomputer and a power amplifier speaker. The bed structure is provided with a gap; the wheelchair structure can be deformed into a flat bed shape. The wheelchair structure can enter the bed structure into the gap and be deformed into a planar bed plank; at this time, the bed structure and the top surface of the wheelchair structure are spliced ​​to form a complete bed surface.

[0042] The bed structure includes a main body, a rollover structure 1, a guardrail structure 3 and a locking structure 4; a rectangular relief gap is opened in the middle of the left and right sides of the main body. The tail end of the main body part of the gap is communicated, and the head end of the main body part is not connected. The two rollov...

Abstract

The invention discloses a prone position detection method of a piezoelectric sensor and nursing equipment applying the method. The detection method comprises the following steps: when a user lies on the pressure sensor group, taking a data measured by each pressure sensor as a frame of data; integrating all data into a one-dimensional array; and expanding each element in the one-dimensional array to a corresponding position in the two-dimensional array according to the actual position of the corresponding pressure sensor. The two-dimensional array is converted into an image, elements at different positions in the two-dimensional array correspond to pixel values of different pixel points on the image respectively, and the image reflecting the prone position of the user is obtained. And judging the posture change condition of the user according to the pressure change condition of each pressure detection area. According to the invention, the prone position of the user is identified by using the change condition of the plurality of pressure sensors, and the posture change condition of the user can be detected, so that the real-time monitoring of the critical state of the user is realized.

Description

technical field [0001] The invention belongs to the technical field of medical rehabilitation, and relates to a method for detecting a prone position of a piezoelectric sensor and nursing equipment applying the method. Background technique [0002] In the context of an aging population, the country, society, and families have an increasing demand for nursing bed products, especially for nursing beds with high intelligence, good performance, and multiple functions. Due to the late start, my country's nursing bed industry is still in a relatively backward position compared with developed countries, and the existing nursing bed products generally have the shortcomings of imperfect functions and single functions. Contents of the invention [0003] The object of the present invention is to provide a method for detecting a prone position of a piezoelectric sensor and a nursing device applying the method. [0004] In a first aspect, the present invention provides a method for de...
