Abstract
A ball combination module capable of detecting and regulating a posture pressure has the requirement of regulating individual independent ball pressures and lifting and lowering functions and mainly includes one or multiple sets of pressure controlling ball modules. Each pressure controlling ball module is connected to a cylinder connected to an external pressure source and is configured with an independent inflating/deflating electromagnetic valve set including a pressure-sensing intake control electromagnetic valve of controlling inflation, a deflation control electromagnetic valve of regulating deflation and a pressure sensor. The external pressure source has a pressure regulator providing a stable pressure gas source. A main gas supply conduit connected to multiple shunts provides inflation and deflation for all the pressure controlling ball modules. The pressure controlling ball modules are combined to constitute a large-area support region and achieve the dot-like pressure regulating and lifting and lowering functions for the comprehensive single ball.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0022] Referring concurrently to
[0023] Upon implementation, the combination board 10 can be directly formed by a plate having a required area size, or by bridging multiple small plates having inverse-U shaped cross-sections into an integrally large-area type and forming equally spaced fixing holes 11 on the surface of the combination board 10, so that it can be combined with the ball 22 and the cylinder 23 simply and conveniently.
[0024] Referring to
[0025] Referring also to
[0026] The inflating/deflating electromagnetic valve set 30 includes a gas conduit 31 connected to a deflation control electromagnetic valve 33 and a pressure-sensing intake control electromagnetic valve 32. The pressure-sensing intake control electromagnetic valve 32 has one end connected to the cylinder 23, and the other end that can be connected to an external pressure source 40 providing the inflation conduit and control. A free end of the deflation control electromagnetic valve 33 provides the deflation conduit. The inflating/deflating electromagnetic valve set 30 is further provided with electromagnetic valve control lines 321 and 331, and the pressure-sensing intake control electromagnetic valve 32 is provided with a pressure sensor 34 at an air inlet connected to the ball 22. The pressure sensor 34 has a sensor transmission cable 341 to be connected to the external computer apparatus, so that the detected pressure of each pressure controlling ball module 20 obtained by the pressure sensor 34 is inputted to the computer apparatus for determining the bearing pressure and time, and further regulating the support mode with the softness formed by the lifting and lowering of the cylinder 23 and the regulated pressure of the pressure controlling ball 21.
[0027] The external pressure source 40 is a large gas supply source, which may be actually, for example, a high pressure steel bottle containing a high-pressure gas, an air compressor or the like. Also, the external pressure source 40 has a pressure regulator 41, a main gas supply conduit 42 and multiple shunts 43 connected together to provide gas pressure sources for all the pressure-sensing intake control electromagnetic valves 32, respectively. The pressure regulator 41 can regulate the maximum pressure to be used, and provide the inflating source to the pressure-sensing intake control electromagnetic valve 32 of each pressure controlled ball module 20 through the main gas supply conduit 42 and all shunts 43.
[0028] Referring again to
[0029] Upon implementation of forming the anti-pressure-ulcer board pad 1 by a fixing board 10 having the required size and the pressure controlling ball module 20, the pressure regulator 41 firstly regulates the highest pressure value upon use. Next, the high-pressure gas is provided to the inflation gas sources for all the pressure controlled balls 21 from the main gas supply conduit 42 through the shunts 43 and through the external pressure source 40.
[0030] At this time, the circuit control system 50 enables the electromagnetic valve controller 51 to open all the pressure-sensing intake control electromagnetic valves 32 and inflate the pressures in the balls 22 to the pressure values set by the pressure regulator 41. The pressure sensor 34 at the gas inlet portion on the pressure-sensing intake control electromagnetic valve 32 detects and feeds back the pressure signal to the circuit control system 50, which checks whether the pressure value is correct, and the pressure-sensing intake control electromagnetic valve 32 is closed when the set pressure value is reached. If the pressure in the ball 22 is higher than the set pressure value, then the deflation control electromagnetic valve 33 is enabled to deflate. Each pressure sensor 34 transfers the pressure signal to the signal analyzing processor 52 and the circuit control system 50, and the pressure parameters are calibrated. Then, the fast switch operation of the inflating/deflating electromagnetic valve set 30 is used to regulate the pressure of the gas source of each pressure controlling ball 21 entering the gas volumes of the ball 22 and the cylinder 23. Thus, it is possible to regulate the lifting and lowering effects of the cylinder 23 best fit with the support of the human body and the pressure regulation function of the softness of the ball 22.
[0031]
[0032] According to the above-mentioned explanation, it is obtained that the invention adopts multiple independent pressure controlled balls having the independent height and pressure regulating functions, and the modularized design can freely construct the mattress structure by longitudinal or transversal combinations. It is possible to take one single set of pressure controlled ball modules to constitute a small-type board pad pattern to function as the wheelchair cushion according to the actual usage requirement, or to take multiple pressure controlled ball modules to constitute a board pad pattern with a large surface area to function as a mattress. Furthermore, the pressure controlled ball module has multiple independent electromagnetic valves provided with pressure sensors to independently detect the local single-point pressure values of the human body contacting the pressure controlled ball, wherein the detected pressure values are analyzed to individually control the balanced pressures in the pressure controlled ball and the soft/hard modes.
