Hygienic attachments for therapy lasers

DETAILED DESCRIPTION OF THE INVENTION In FIG.
1, numeral 1 indicates a moulded plastic half-section of a direct beam laser therapy unit head, numeral 2 indicates a laser tube, functioning as a laser beam generator numeral 3 the ballast resistors and numeral 4 the multicore, shielded electrical cable which connects said head assembly to the laser power supply at control unit.
The laser output beam is indicated by numeral 5 as it propagates through the channel indicated by numeral 6 which is completed when the second half of the mould is attached to said bottom half 1.
Numeral 7 indicates the locating groove for correctly orientating the invention onto the laser therapy head whilst the groove indicated by numeral 8 is the one used to firmly attach said invention onto said head.
Numeral 9 indicates a groove to locate either an optically polished window or an optically polished laser beam attenuator which also acts as a stop for glass containers filled with various liquids which can be inserted in channel 6 and through which laser beam 5 can propagate.
Numeral 10 indicates the recess for the safety switch necesary on Class II therapy lasers to block beam 5 as required.
Numeral 11 indicates the moulded cradle which accepts the "O" ring mounting around the tube 2.
In FIG.
2, numeral 12 indicates the grooves in body 1 into which are positioned the springed conductors to complete the electrical circuits for the skin resistance electrodes used to locate the acupuncture points and activate the laser beam once they have been found.
Numeral 13 indicates the location points used to firmly clip the top and bottom sections 1 together prior to gluing.
In FIG.
3, numeral 14 indicates the body of the invention which fits over the end cone of body 1 shown in the previous Figures.
Numeral 15 indicates the circular rib which fits into groove 8 of the cone of body 1 shown in FIG.
1 so as to lock the invention into position during operation.
Numeral 16 indicates the central tube of the invention which fits into channel 6 of FIG
