USPTO Abstract
A device 1 for unsheathing the needle of a syringe has a cylindrical housing on which is mounted a driver sleeve 13 that can be moved along the outside of the housing. The driver is coupled to resilient fingers which form a collar on the inside of the housing. A syringe with a sheath covering its needle can be inserted into the housing through an opening 12 to engage with a syringe carrier (28, figure 5). To remove the sheath, the driver is pulled rearwardly until it meets a step 15 in the housing, causing the fingers to ride over the sheath and engage a gap between the top of the sheath and the syringe barrel. The driver is then pushed forwards, back to its original position, causing the fingers to push the sheath off the needle (figure 11).
