AI Technical Summary

Problems solved by technology

Failure of both sides of the clamp to fully engage can reduce the clamping force on the conduit by up to 50% and prevent the mating sealing surfaces from coming together

Embodiment Construction

[0021] first reference figure 1 and 2 , which shows conduit clamp 1 in the open state. The conduit clamp 1 comprises a base 2 and a cover 3 pivotably mounted to the base 2 at 10 . The conduit clamp 1 is arranged to receive the conduit 20 into the vertical through hole / port 7 and into the open channel 8 which communicates with the through hole 7 . The channel 8 comprises an inclined part and a (lower) horizontal part. The through hole 7 and channel 8 are substantially the outer diameter of the catheter and form a tight fitting path for the catheter. When the cap 3 is closed to form a pinch, the lower portion 9 of the cap 3 pushes the conduit into the passage 8 and deforms the conduit within the passage without appreciably reducing the cross-sectional area through which fluid can flow through the conduit. This controlled deformation of the catheter advantageously allows the catheter to be securely clamped.

[0022] The cover 3 comprises towards its free end two spaced apart...

Abstract

A catheter clamp (1) comprising a base (2) and a pivotable cover (3), the cover arranged to be capable of adopting an open condition and a clamped condition, the clamp further comprising a resiliently biased displaceable latch (12) to releasably retain the cover in the clamped condition, wherein the latch displaceable on and relative to a support surface (11) which supports the latch, so as to release the cover from the clamped condition.

Description

technical field [0001] The present invention relates to conduit clamps. Background technique [0002] We have realized that there are various disadvantages in the function and efficiency of the known methods for fastening the covers of conduit clamps into the clamped state. [0003] Broadly speaking, known catheter clamps consist of two (plastic) elements: a base and a cover / cover, which are hinged together so that when in the open state, the catheter can pass through the base and the base is in the skin insertion position Adhesively adheres to the patient's skin all around. The cover can be manually pivoted to clamp the conduit and the retaining clip means operated to hold the cover in a clamped condition. [0004] The retaining clip device usually comprises two lugs forming the elastic part of the cover. As the cover approaches the clamped state, the lugs are deflected by the hole-defining surface in the base. When the lug has passed through the hole, the lug springs b...
