    Abstract: A device intended to be positioned close to a joint between two parts, the device including a first interface carried by a first of the two parts and a second interface carried by a second of the two parts, the device including at least one connection between the first interface and the second interface. The connection includes two cylinders mounted in parallel so that each cylinder is connected by its output rod to the first interface and by its body to the second interface, the simultaneous displacement of the two output rods allowing, when in use, movement of the second part of the joint relative to the first part of the joint. A general system including the device as well as a fluid-supply unit for said device are also provided.

    Abstract: A gas circuit control system of a pneumatic cardiopulmonary resuscitation pressing device comprises a gas control valve (3) communicating with a piston cylinder (2) of the pneumatic cardiopulmonary resuscitation pressing device, and a spool of the gas control valve (3) controls gas charging and discharging of the piston cylinder (2) when reciprocating; and at least one end of the spool of the gas control valve (3) is provided with a gas cavity, the gas cavity communicates with a gas source through a miniature electronic control valve (4), and the miniature electronic control valve controls gas charging and discharging of the gas cavity to drive the spool of the gas control valve (3) to reciprocate. The gas circuit control system of a pneumatic cardiopulmonary resuscitation pressing device can greatly reduce the power consumption of electronic control pneumatic pressing devices

    Abstract: A stimulation device is described having a pressure field generating device which has a cavity and a medium influencing arrangement. The stimulation device uses a first check valve arrangement, arranged inside the cavity between the application opening and the medium-influencing arrangement, and is movable at least in sections in the direction of the application opening and away from it and has a first check valve which is designed to close in the direction of the application opening and to open in the direction of the medium influencing arrangement, wherein the cavity has a first section and a second section, and a second check valve arrangement, which connects the first section of the cavity to an outside of the stimulation device and has a second check valve.
