摘要:
A needle tip protective device for use with percutaneous entry needles. In one embodiment, the needle tip protective device includes a needle guard slidably mounted on a hypodermic needle, the latter having a needle tip located at the distal end thereof, and a change of profile formed medially there along. The needle guard is movable along the hypodermic needle and engageable with the change in profile formed thereon. The engagement with the change in profile is configured to correspond with the ability of the needle trap to entrap the needle tip once the needle trap has advanced the sufficient distance distally along the hypodermic needle. In further refinements, the needle trap may be biased toward the distal needle tip of the needle.

A method and apparatus for enhancing an applause is described. The present invention acts as a container for food or beverages and once the food or beverage is consumed may be converted into an apparatus to enhance an applause or boo. One embodiment of the present invention is an apparatus for holding a beverage container. The apparatus for holding the beverage container has a top, a bottom, and at least two sidewall sections which may be selectively detached and assembled with matching components. The device may be selectively adjustable to accommodate containers of various sizes and shapes. By detaching the sidewall sections in at least one place the sidewall sections may be open and closed. The open and closing motion may be done such that when the sidewall sections are closed upon one another they hit to make an audible sound.

This invention is a carpule-using syringe assembly having a needle protected to minimize the chance of accidental needle-stick. There is a carpule having a pierceable end and a syringe body for receiving and holding the carpule with the pierceable end adjacent an opening in an end portion of the syringe body. A cap is disposed over the pierceable end. The cap includes a support portion disposed in the opening. There are carpule-piercing portions for piercing the pierceable end of the carpule through the cap and a needle having a patient-piercing end. A retractable protective sleeve formed of a plurality of longitudinal slats is disposed over the patient-piercing end of the needle. Finally, there is provision for attaching the needle and the retractable protective sleeve in combination to the support portion with the needle in communication with an interior portion of the carpule through the carpule-piercing portions.

A needle guard assembly having a resilient arm extending from a base situated to slide along the shaft of a needle. In one implementation the needle guard has an elongate containment member that rides with the resilient arm and is co-operable with the resilient arm to effectuate a covering of the entire distal tip of the needle upon the needle being refracted into the needle guard.

A single use syringe in which the single use aspects are accomplished by a lumen spike which is forced into the lumen bore to seal the passageway from the syringe body to the hypodermic needle. Fail-safe characteristics to prevent bypassing the single use provisions are provided by having a frangible area of the endwall holding the lumen break out at a force less than that required to force the lumen spike out of the lumen bore. This aspect can also be used to improve other approaches to single use syringes. The lumen spike can be formed as part of the piston/plunger and the piston/plunger can be a unitary device useful in all syringes.
