Cannula or catheter assembly
First Claim
1. A cannula or catheter assembly having a cannula or catheter tube (1, 22) to be inserted in a patient, and a socket (2, 23) therefor which has a straight passageway (3, 24) to which the tube is connected, wherein a connecting housing (4, 27) is formed integral with or is releasably attached to the socket (2, 23) and has a straight through-channel (5, 28) which is surrounded by a wall and is coaxial with the passageway of the socket and connected at one end to said passageway, its opposite end being provided with connecting means (6, 29) for coupling a hose, a syringe or the like, wherein said through-channel of the connecting housing accommodates an easily flexible hose section (7, 31) sealing against the channel wall, wherein the wall of the connecting housing that surrounds said channel is provided at a location between the ends of said hose section with at least one through-opening in which a pressure body (9, 32) is movable between one position at which said pressure body projects into said channel and maintains a portion of the hose section in a compressed closing state, and another position in which said portion of the hose section is substantially unaffected by said pressure body, and wherein a slide member (11, 35) mounted on the outer side of the wall surrounding said channel is movable back and forth in the longitudinal direction of the channel and has an oblique surface (14, 33) facing said pressure body and adapted, when said slide member is moved to displace the pressure body between said two positions.

Abstract
A cannula or catheter assembly has a cannula or catheter tube in a socket with a straight passageway. In order to equip such an assembly with a cheap and safe closure device which is easy to maneuvre without causing any movements injurious to the assembly, a connecting housing is fixedly or releasably connected to the socket and has a straight through-channel which is connected to the passageway of the socket and accommodates a hose section which seals against the channel wall and, to permit closing the through-channel, can be compressed at a location between its ends by means of at least one pressure body disposed in an opening in the wall of the through-channel and operable by means of a slide member movable in the axial direction of the through-channel on the outer side of the connecting housing.
