Title: Cigarette
IPC: A24D1/10
Filed: 1991-03-12
Granted: 1992-11-10
Abstract: The invention relates to a cigarette consisting of a tubular wrapper, preferably of paper, which is filled with tobacco, with or without a filter unit, and the objective is deliberately to draw the attention of the smoker, as he smokes the cigarette, to the fact that, at the start of smoking of the cigarette, he inhales fewer harmful substances per unit of length than towards the end thereof. This is achieved in that markings are applied to the outside of the tubular wrapper which, as smoking of the cigarette progresses, refer to the increasing content of harmful substances for each unit of length of the cigarette smoked. <IMAGE>

Title: Syringe with a tubular housing for receiving an ampoule
IPC: A61M5/42
Filed: 1992-03-18
Granted: 1994-04-25
Abstract: The syringe has a tubular housing 1, for receiving an ampoule, and an injection needle 3, provided on the one end face. The syringe is operated by a plunger shank 4 projecting from the other end face of the housing 1. The end of the housing 1 bearing the injection needle 3 is received by a sleeve 12, with the respect to the end face of which the needle 3 projects somewhat. This end face has a peripheral collar, projecting with respect to the tip of the needle. The part of the housing 1 having the plunger shank 4 is received by a bushing 6, which is displaceable axially with respect to the housing 1. This bushing 6 extends approximately 2/3 over the length of the housing 1. Its base bears against the plunger shank. The end face facing the injection needle 3 has a collar 9 as a finger support. Arranged on the sleeve 12 are tongues 17, which are resilient on diametrically lying sides, extend in the axial direction of the sleeve 12 and the free edges of which protrude beyond the peripheral collar 16. With a syringe of this type, which has been developed in particular for diabetic persons, a disabled patient can inject with just one hand the insulin vital to him. With such a syringe, the necessary pinch of the skin is formed, the needle is inserted to the correct depth and the plunger is operated. <IMAGE>
