Formed in the outer periphery of the enlarged cylindrical plug portion 10 is an eccentric groove 12 adapted to receive the collar 7 which has an outer cylindrical surface and an eccentric opening therein providing a collar having a shape corresponding to the shape of the eccentric groove 12, for a purpose to be subsequently described. Projecting into the eccentric groove 12 from one side thereof is a projection or stop 15 which is received in a circumferentially extending slot 18 formed in one end of the collar 7, whereby when the collar 7 and plug 6 are properly assembled, the extent of rotation of the collar 7 relative to the plug 6 is limited by engagement of the ends of the slot 16 with the stop. Alternatively, the circumferentially extending slot 16′ may be intermediate the ends of the collar 7′ and the projection or stop 15′ may be a pin projecting into the slot from the bottom of the groove 12′ as shown in
The collar 7 is made of a flexible material which may be of plastic such as nylon, and is split as shown to facilitate assembly of the collar onto the plug, and insure frictional sliding contact between the collar and inner diameter of the outer member 2 even when the collar is concentric on the plug. Accordingly, rotation of the outer member 2 relative to the inner member 1 will cause the collar 7 to rotate with the outer member unless there is engagement between one end of the notch in the collar and the projection 15 on the plug precluding further rotation of the collar in an unlocking direction or the collar is already in the eccentric locking position precluding further rotation of both the collar 7 and outer member in the locking direction. The forward end 20 of the plug 6 may be tapered as shown to provide a ramp for sliding of the collar up onto the enlarged cylindrical portion 10 and into the groove 12 during assembly.
To assist in guiding of the outer member 2 along the inner member 1 during longitudinal adjustment, an end cap 21 is provided on the telescoping end of the outer member which has a close sliding fit with the outer diameter of the inner member 1 as shown in
From the foregoing, it will now be apparent that the cam lock of the present invention is easily operated by relatively rotating the telescopic members in one direction or the other to obtain locking and unlocking of such members. The lock has unidirectional characteristics providing to the user known directions for always tightening and untightening the lock, thereby substantially eliminating the chances of inadvertent overtightening or loosening of the lock.
Plastic stretch films are well known in the art (U.S. Pat. Nos. 8,435,622; 8,053,055; 7,682,683) and may take any convenient form. They may be opaque or substantially transparent. Alternatively, they may be colored, such as, for example, skin toned. The films may be composed of any suitable material, such as, for example, a polyolefin (i.e., polyethylene, polypropylene or polybutylenej, polyvinyl chloride or ethylene vinyl acetate.
Although the preferred embodiments of the invention have been illustrated and described in detail, it will be readily apparent to those skilled in the art that various modifications may be made therein without departing from the spirit of the invention or from the scope of the appended claims, For example, the system may be designed for single usage applications or for situations where multiple lengths of film are separately dispensed for applications to multiple sites; either on the same or different patients. Moreover, the film may assume any convenient shape, design or construction. For example, the film may be perforated, it being understood that the system is designed for multiple wrappings of the perforated sheet around the designated site so that the perforations overlap with non-perforated sections to provide a waterproof and protective covering. Also, those skilled in the art will appreciate that any convenient telescoping mechanism may be employed in the above described optional embodiment of the invention wherein the supply of film may be extended along the length of the handle to enable application of the film to hard-to-reach areas of the human or non-human animal undergoing treatment.
The mixture of manuka honey, activated charcoal and tea tree oil is preferably compounded in powdered form. Each of manuka honey, activated charcoal, and tea tree oil are available commercially in powdered form. Powdered manuka honey is available from Manuka Health Co. [Newmarket, Aukland, New Zealand]. Powdered tea tree oil and powdered activated charcoal may be obtained from Alibaba Group [San Mateo, Calif.].
The mixture, in its broadest aspect comprises, by weight, from about 5 to about 25% of powdered manuka honey, from about 15 to about 35% of powdered tea tree oil, and the remainder, powdered activated charcoal.
