Safety device for connection of a syringe with the mouth or opening of a bottle containing a drug or a small tube for drug delivery from the syringe

摘要

The invention relates to a device to one end of which a syringe can be connected and to the other end of which the mouth or opening of a bottle containing a drug or medicine can be connected. The device comprises a closed chamber having enclosed therein a needle which is in connection with the syringe. Members are provided by means of which the mouth or opening of the bottle is steadily connected to the device and means enabling the needle to perforate a seal plug and then a small rubber plug mounted on the bottle only when the device is blocked onto the bottle so that in any case it cannot be disconnected therefrom. Such a device can be disconnected from the bottle only after the needle has been caused to reenter the closed chamber, so as to prevent any possible dripping of the liquid outside of the device.
