摘要:
The invention relates to a system for performing in vivo pressure measurements, comprising one or more pressure sensors (14), a connector module (20) provided with one or more electrical coupling elements for the one or more pressure sensors and one or more coupling means (10) for a catheter. The one or more coupling means for a catheter are each provided with at least three ports and a tap for coupling two of the three ports as desired. According to the invention each of the one or more coupling means is embodied as a coupling module which is releasably connectable to the connector module, and the pressure sensors (14) are arranged on the coupling modules (10). The invention also relates to a coupling module (10) for a catheter as described as component of the system (1) according to the invention.

A catheter procedure system includes a base and a robotic mechanism having a longitudinal axis and being movable relative to the base along the longitudinal axis. The robotic mechanism includes a robotic drive base including at least one drive mechanism, a cassette operatively secured to the robotic drive base, a rigid guide coupled to the cassette and fixed relative to the robotic mechanism and a flexible track having a distal end, a proximal end and a plurality of reflective sections. At least a portion of the flexible track is disposed within the rigid guide. The robotic mechanism also includes a position detector mounted to the robotic drive base and positioned beneath the flexible track. The position detector is configured to detect light reflected off of the reflective sections of the flexible track and to determine the position of the distal end of the flexible track based on the detected reflected light.

Valve devices are provided for draining fluids from and/or infusing fluids into a patient's body that include a housing including first, second, and third connectors, a primary fluid path communicating between the first and second connectors, and a secondary fluid path communicating from the primary fluid path to the third connector. First and second valve members are movable within the housing between first positions wherein the valve members do not obstruct the primary fluid path and second positions wherein the primary fluid path is at least partially closed. The third connector may be configured to prevent fluid flow therethrough unless a mating connector is fully coupled thereto. The valve members may be selectively closed to isolate portions of the flow path to allow a source of vacuum or fluid coupled to the third connector to aspirate or infuse fluid along portions of the primary fluid path.

A treatment tool is made to protrude at an appropriate position with respect to an endoscope while maintaining a high flexibility. Provided is a medical tube (1) including: a first lumen (4) that forms an endoscope channel by penetrating through a tube main body (2), which is constituted of a material possessing flexibility, in a longitudinal-axis direction; a plurality of second lumens (5 and 5a) that are capable of forming treatment-tool channels by penetrating through the tube main body (2) in the longitudinal-axis direction at a periphery of the first lumen (4) with spacings therebetween in a circumferential direction; a first indicator (12) that is provided on an inner surface in the vicinity of a distal end of the first lumen (4) and that specifies a circumferential-direction position of any one of the second lumens (5 and 5a) with respect to the first lumen (4); and a second indicator (13) that is provided at a proximal end of the tube main body (2) and that indicates the second lumen (5a) specified by the first indicator (12).

A connector includes a connector main body (10) having a flow path (17), an insertion body (23) having a tip serving as a connection opening (24) for the flow path (17), a valve body (22) formed of an elastic body and arranged on the tip of the insertion body (23) to block the connection opening (24), and a cap (21) which holds the valve body (22) together with the insertion body (23). The valve body (22) includes a valve main body (30) having slits (32, 33), an inner projection (35) formed in an annular shape having an outer diameter smaller than the inner diameter of the insertion body (23) and projecting from a bottom face (30b) of the valve main body (30), and a pair of outer projections (36) arranged point-symmetrically to each other with respect to the axis of the inner projection (35), each of the pair of outer projections (36) projecting from the bottom face (30b) on the outer side in the radial direction with respect to the inner projection (35) and being arranged on the inner side of the insertion body (23).

A connector (10) for connecting a medical tube set to a medical container, comprises a collar (12) connectable to a container, a cap (14) comprising at least one opening (30) for receiving a tube of a tube set, and an annular seal (16). The cap (14) is located in the collar (12) between an inner surface of the collar and the seal (16). The cap (14) is rotatable relative to the collar (12). The collar (12) comprises a generally cylindrical side wall open at its upper and lower ends and an annular flange projects inwardly from the side wall at the upper end. The cap (14) comprises a disc defining at least one opening and having an outer annular rim which locates between a lower surface of the annular flange on the collar (12) and the seal (16).
