SLEEVE PART AND MEASURING DEVICE
The two inflatable sleeve cushions (10) which can be arranged in the receiving tubes (9) are each connected by means of a connection (11) at the interface between sleeve part (2) and base part (3) to the pressure generation and pressure control system in the base part (3). A valve device is preferably provided on the connection (11). The channels (19) that connect the respective connection (11) to the respective sleeve cushion (20) are formed in the main body (21) of the receiving body, said main body being produced from plastic by means of injection moulding, and are covered towards the outside by means of a cover (20). The connections (11) are disposed one behind the other in the direction parallel to the axial direction of the receiving tubes (9). From there, each channel (19) is first guided upwards, then diagonally to the side, and finally downwards to the fluid access opening (22) of the respective sleeve cushion (10).

Dual Mode Non-Invasive Blood Pressure Management
The present specification describes methods and systems for on-inflate non-invasive blood pressure (NIBP) measurement suitable for cuffs of various sizes. In embodiments, an adapter hose connecting the cuff to the NIBP device is dynamically identified. Embodiments provide a restriction in at least one of the valves in the NIBP device to enable a controlled release of air from the device during the cuff inflation process.

Valve, gas control device, and sphygmomanometer
A gas control device includes a pump, a valve, a cuff, and a controller. The valve includes a first plate having a first vent hole and a first vent hole, a channel forming plate having an exhaust hole and an exhaust channel, a second plate having a second vent hole, and an edge separation plate. A manchette rubber tube in the cuff is joined to the periphery of the second vent hole in the second plate by an adhesive, and thus the valve is connected to the cuff. The exhaust hole is opened to the atmosphere. The pump includes a pump housing having a discharge hole and a discharge hole. The upper surface of the pump housing is joined to the bottom surface of the edge separation plate.

CONTROL DEVICE FOR CONTROLLING A MEASUREMENT SYSTEM FOR MEASURING BLOOD PRESSSURE
The invention relates to a control device for controlling a measurement system for measuring blood pressure and optionally hemodynamic parameters of a subject. In a first measurement time period T.sub.1, for measured pressure pulses, features are determined, which characterize the respective pressure pulse. Based on the features, start values are determined and, based on the start values, a start curve TPW_F-curve is formed. The measurement system is controlled such that, after the start curve has reached a first maximum, a second measurement time period T.sub.2 succeeds, wherein a blood pressure value is determined based on the pressure measured in the second measurement time period. It has been found that by using the maximum in the first measurement time period for defining a start point for the actual blood pressure measurement, a blood pressure value and optionally also hemodynamic parameters of a subject can be determined very accurately and fast.
