<p>The instrument comprises a cylindrical sleeve which contains a suppository and of which a front end is designed to enter the orifice. The rear end of the sleeve fits removably to the delivery end of a syringe so that the sleeve forms an axial extension of the syringe. When the syringe's piston is manually advanced, the front of the piston ejects the suppository from the front end of the sleeve into the orifice. Pref. the front end of the sleeve is formed as a nose-cone which is longitudinally split into several tongues which can be sprung open but normally resume the nose-cone profile. Pref. the sleeve is the package in which the suppository is distributed. The syringe is sterilisable and the sleeve, which can be disposable, provides hygienic protection for the suppository right up to the moment of insertion. Insertion is partic. effective so that the risk of subsequent, inadvertent ejection is reduced.</p> |
