Abstract
A catheter clamp comprises a base (1) for securing by adhesion to the skin, a hole (2) in the base for passage of a catheter tube (3), a curved tube support surface (14) for supporting the tube which is bent in use through about 90.degree., and an arm (6) pivoted at (8) between parallel upstanding side walls (4) on the base. The arm (6) has a curved portion (22) extending eccentrically of the pivot (8) which urges a tube portion (23) above the hole (2) into a vertical channel provided in a post (12), and grips the tube when the arm is pivoted to an operative clamping position. The arm is held by retention means (24, 25) in the clamping position. In another embodiment (FIGS. 8, 9) the manually operable clamping means is provided by a slider (50).
Claims20
A catheter clamp comprising a base adapted to be secured to the skin, an aperture in the base through which a catheter tube can be inserted, curved tube support means for supporting in use a curved portion of the tube with said tube support means having a passageway whose longitudinal center extends through an arc, manually operable clamping means which is manually displaceable relative to the base from an inoperative position, in which movement of the tube passing through said aperture is substantially unrestricted by the clamping means, to an operative clamping position in which the tube is gripped between first and second clamping surfaces and with at least one of the surfaces curved along a longitudinal direction of the passageway, one of said clamping surfaces being provided on the clamping means, and the other of said clamping surfaces being provided on an abutment which is fixed relative to the base.
A catheter clamp including a base housing to be secured to a patient's skin, comprising:
- an aperture having a center line longitudinal aperture axis in said base housing through which a catheter tube can be inserted;
- a curved support structure smoothly curved along a longitudinal axis of a passageway to support the catheter tube passing through the aperture in said base, said curved support structure longitudinal axis diverging from the center line longitudinal aperture axis;
- and
- manually operable clamping means which is displaceable relative to said base housing and when engaged to the catheter tube the tube is gripped between a first and a second clamping surface, said first clamping surface being provided on said clamping means and said second clamping surface being provided on an abutment fixed relative to said base housing.
