This injection device comprises a housing having a handgrip for operating it. A collapsible fluid container is adapted to fit in the housing under the pressure element of the handgrip. The container has a fill opening with a closure and an injection stem extending out of the housing so that when the handgrip is squeezed, the collapsible fluid container will compress the fluid within it and drive the fluid out through the stem. Conversely when the fluid container is compressed the stem can be submerged, in fluid and the handgrip spread to enlarge the container and suck fluid into the container.

Why it's free to use
- Filed March 28, 1994 and granted August 12, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 28, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 28, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
