Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
247 words
A cannula or catheter assembly having a cannula or catheter tube to be inserted in a 100 patient, and a socket therefor which has a straight passageway to which the tube is connected, wherein a connecting housing is formed integral with or is releasably attached to the socket and has a straight through-channel which is 105 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 for coupling a hose, a syringe or the like, wherein said 110 through-channel of the connecting housing accommodates an easily flexible hose section sealing against the channel wall, wherein the wall of the connecting housing that surrounds said channel is provided at a location between the ends 115 of said hose section with at least one throughopening in which a pressure body is movable between one position in 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 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 facing said pressure body and adapted, when said slide member is moved, to displace the pressure body between said two positions.
Claim 2
Dependent Claim
247 words
A cannula or catheter assembly having a cannula or catheter tube to be inserted in a 100 patient, and a socket therefor which has a straight passageway to which the tube is connected, wherein a connecting housing is formed integral with or is releasably attached to the socket and has a straight through-channel which is 105 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 for coupling a hose, a syringe or the like, wherein said 110 through-channel of the connecting housing accommodates an easily flexible hose section sealing against the channel wall, wherein the wall of the connecting housing that surrounds said channel is provided at a location between the ends 115 of said hose section with at least one throughopening in which a pressure body is movable between one position in 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 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 facing said pressure body and adapted, when said slide member is moved, to displace the pressure body between said two positions.
Claim 3
Dependent Claim
34 words
Assembly as claimed in claim 1, wherein said oblique surface is arranged on a resilient portion of the slide member in order that the slide member be pressed elastically yieldingly against said pressure body.
Claim 4
Dependent Claim
49 words
Assembly as claimed in claim 1 or 2, wherein the wall of the connecting housing that surrounds said through-channel has two diametrically opposed openings each accommodating a pressure body, and wherein said slide member has two opposed oblique surfaces each of which abuts on one of said pressure bodies.
Claim 5
Dependent Claim
33 words
Assembly as claimed in claim 3, wherein said slide member is substantially U-shaped in cross section, having a web and two flanges on the inner sides of which said oblique surfaces are arranged.
Claim 6
Dependent Claim
233 words
Assembly as claimed in claim 3 or 4, which is in the form of an infusion cannula assembly with a cannula tube of flexible material and which also includes a p uncture needle unit having a head releasably accommodated in the connecting 9Ei means of said connecting housing and a metal puncture cannula tube which projects from said head and is sharp-pointed at its free end remote from said head and which passes from this head through said through- channel of the connecting housing, said hose section disposed therein, said passageway of said socket and on through the flexible cannula tube to project slightly with said sharp-pointed end from the distal end of said flexible cannula tube with respect to the connecting housing, the head of the puncture needle unit being provided with two finger grip wings of elastic material which extend from said head in the same direction on either side of the connecting housing in the longitudinal direction thereof, wherein the facing surfaces of said wings are provided with cam surfaces which are adapated, as the puncture cannula tube of the puncture needle unit is extracted from the infusion cannula tube, the socket and the connecting housing, yieldingly to entrain the slide member 4 GB 2 034 185 A 4 and displace it on said connecting housing to a position in which the pressure bodies are pressed against the hose section.
Claim 7
Dependent Claim
24 words
