Estimating the term…
A disposable insertion tip for a body cavity cleaning or irrigation device includes at least one tear strip. Once attached to the cleaning device, the insertion tip is sealingly locked in a predetermined position permitting liquid to be dispensed into a body cavity and used liquid to be returned from the body cavity through respective interior chambers provided in the insertion tip. The tip cannot be removed without first tearing the tear strip, which once torn, disables the sealing capability of the tip relative to the cleaning device. The insertion tip is preferably made from a transparent material which permits a user to view the efficacy of a cleaning procedure and to note when removal of the tip is required.
A body cavity cleaning device, including a handpiece which receives a supply of liquid under pressure for cleaning a body cavity and an insertion tip, said tip being releasably attachable to said handpiece and including release means for selectively releasing said insertion tip from said hand piece wherein engagement of said release means prevents effective reuse of said insertion tip, said insertion tip further including a pair of interior chambers, an inlet chamber for discharging liquid into the body cavity from said handpiece and an outlet chamber for returning used liquid from the body cavity to a return line of said handpiece.
In combination, a disposable insertion tip for use with a body cavity cleaning device, said device including a handgrippable syringe which receives a supply of liquid under pressure for cleaning the body cavity and includes a return line for receiving used liquid and particulates from the body cavity, said insertion tip being releasably attachable to said syringe and including engageable release means for selectively releasing said insertion tip from said syringe, wherein engagement of said release means prevents effective reuse of said insertion tip in conjunction with said handgrippable syringe.
A disposable insertion tip which is releasably attachable to a body cavity cleaning device, said insertion tip including release means for preventing said insertion tip from being removed from the cleaning device without disabling said insertion tip so as to prevent reuse thereof.
A method for disabling the use of a syringe tip relative to an irrigation syringe, said method comprising the steps of:
A disposable insertion tip for use with a body cavity cleaning device, said insertion tip being adapted for releasable attachment to said device and including release means for selectively releasing said insertion tip from said device, wherein said release means upon engagement thereof prevents effective reuse of said insertion tip in conjunction with said device, said tip being capable of circulating liquid to and liquid and particulates from a body cavity, said tip further including means for filtering said particulates.
