摘要:
A method and apparatus for supporting a patient on a mattress. The apparatus includes a mattress which has at least one controlled release chamber with a top face and a bottom face. A flexible film of a thin metal foil is linked to the top face, while at least one impedance varying device is linked to the bottom face of the chamber. The impedance varying device is an integral part of a measuring electronic bridge. Changes in the impedance as a result of movement of the top face with respect to the bottom face activates a servo control which increases or decreases the inflation pressure within the chamber to make certain that the distance between the top face and the bottom face of the chamber is maintained at a predetermined distance. The method of this invention includes the steps of providing a mattress having at least one closed or controlled release chamber having a top face and a bottom face, providing a measurement device which includes a flexible film of a thin metal foil linked to the top face of the chamber and cooperating with at least one impedance varying element linked to the bottom face of the chamber, the impedance varying element being integral with a measuring electronic bridge, and measuring spacing between the top face and the bottom face to provide control of the supporting action of the mattress as a function of the patient's morphology and position on the mattress.

The present invention relates to a method and apparatus for supporting a body element. The apparatus includes at least one support device with at least one closed or controlled-release chamber, a filling device and an emptying means device for filling said chamber with a filling fluid and emptying the fluid from the chamber, and a distance-measurement device for measuring the distance between a top face and a bottom face of the chamber. The apparatus further includes a reaction-measurement device for measuring the reaction of the support device relative to the morphological data of the body element to be supported, and a control system including a combination device for combining the measurement of the penetration distance d provided by the distance-measurement device and the measurement of the reaction provided by the reaction-measurement device. This combination is advantageously constituted by summing the two obtained measurements. The invention makes it possible to support the element to be supported substantially in a position of equilibrium corresponding substantially to a predetermined float line.

An apparatus for providing access to a computer via two or more alternative keyboard/monitor pairs. The invention comprises a switching box connected between the keyboard/monitor pairs and the computer for switching access between the keyboard/monitor pairs. Access is switched by depressing a key on the keyboard which a user wants to use. An automatic toggling function is executed which switches control to the keyboard upon which a key has been depressed.

摘要:
A fluidized patient support structure in which a mass of granular material is received within an open top container between a fluid diffuser plate and a flexible sheet on which the patient may lie in a supine position. Pressurized fluid passes through the diffuser plate and suspends the granular material in a fluidized form. The diffuser plate has a predetermined variable contour and a predetermined depth of fluidized material thereabove adequate to support a patient in a supine position.

A method and apparatus for rapidly inflating an inflatable chamber. The apparatus comprises inflation means 50 for inflating an inflatable chamber 14 defined by a support device 12 for supporting a patient P. The apparatus 10 comprises at least one first inflation means 52 for performing inflation at a high flow rate and at a low pressure so as to fill the volume of said chamber 14 substantially fully at a low pressure, and a second inflation means 54 for inflating at a low flow rate but at a high pressure to obtain said predetermined inflation pressure in said chamber 14. The invention makes it possible to inflate the chamber 14 rapidly, which is particularly important in medical applications.

A method and apparatus for rapidly deflating a chamber. The apparatus for rapidly inflating an inflatable chamber of determined inflation volume with an inflation fluid comprises an inflation device for inflating said inflatable chamber with an inflation fluid to a predetermined inflation pressure, and further comprises a rapid deflation device for rapidly deflating said chamber by sucking out said inflation fluid at a high flow rate, the rapid deflation device being used on deactivating said chamber, in particular so as to transport it with its volume being reduced to as small as possible.

The invention relates to a method and apparatus for supporting an element to be supported, in particular the body of a patient. The apparatus comprises a support device 20 essentially comprising only at least one closed or controlled-release chamber 21 together with inlet and outlet means 26 via which the filling fluid can be fed in or removed, and an independent control device 40 is provided disposed under the support device 20, said control device 40 comprising filling and emptying means for filling the chamber with filling fluid or for emptying said fluid therefrom and the control means proper 50, 41, 42 for controlling feeding in and removing the filling fluid. The invention makes it possible to simplify manufacture and management of a support for supporting an element to be supported such as the body of a patient.
