Abstract
A means to connect a hypodermic syringe to its bottle of medicament, so that the syringe is in proper alignment to pierce the bottle sealing diaphragm. The means also holds the syringe to the bottle so that a measured amount of medicament may be withdrawn. Also included are sealing caps to retain full sterility of all elements during use and also non-use. The means permits the entire volume of the medicament to be withdrawn in a plurality of measured doses.
Claims10
For use with a liquid-containing bottle having a perforatable closure diaphragm, and a syringe:
- an adaptor cap having means to attach said cap to the bottle above the diaphragm, said cap having a body and a hollow portion extending outwardly from said body and terminating in a larger opening, a guide portion spaced from said larger opening and having converging surfaces terminating in a smaller hole inwardly in said hollow portion, said syringe having a barrel, a projection fittable into said larger opening extending from said barrel and carrying a hollow needle, whereby a user may insert said needle into the larger opening of said hollow portion, and then into said smaller hole and into and through said diaphragm, while the syringe projection enters said larger opening and is retained therein, thereby causing the needle to be axially aligned and penetrate the diaphragm immediately below said hole and causing said syringe and bottle to be frictionally held together.
