Clamp safety lock with printable area

Clamp safety lock with printable area description/claims

This application claims the priority to the U.S. Provisional Application Ser. No. 60/957,343, entitled “Clamp Safety Lock with Printable Area,” filed on Aug. 22, 2007. The specification of the above-identified application is incorporated herewith by reference.

Catheters are commonly used to supply or withdraw fluids to internal areas of the body. Certain catheters are left in place to provide repeated access for such fluid transfers. In these cases, a proximal end of the catheter which remains accessible outside the body must be sealed between uses to prevent fluids from leaking out and contaminants from entering the body.

Tubing clamps are used with many such catheters having proximal ends located at diverse parts of the body. As such catheters may be left in place for extended periods, the clamps may be accidentally opened (e.g., by patient activity). This may cause significant problems, such as infection due to foreign contaminants entering the catheter and contamination of external surfaces by bodily fluids.

In addition, because of the many applications for catheters, it is often useful to provide information regarding the specific use of a catheter. As multiple catheters may be used on a patient for different purposes, easily distinguishing the catheters becomes important.

In one aspect the present invention is directed to a safety lock for a clamp closing a therapeutic fluid conduit, the clamp comprising a clamping end and a locking end which wrap around a fluid conduit receiving space wherein, when in a clamped position, the locking end mates with the clamping end to maintain a clamping projection in the fluid conduit receiving space, the lock comprising a first attachment at a first end thereof, the first attachment being sized and shaped to receive therein a portion of the clamping end, the first attachment abutting the clamping projection to define a maximum travel of the lock along the clamping end toward the locking end and a second attachment at a second end thereof preventing the locking end from moving away from the clamping end.
