Abstract
A medical fluid injection device, a medical fluid transfer device and a method of administering and transferring a medical fluid are disclosed. The device and method may include a compressed gas canister in fluid communication with an expandable elastic bladder positioned within a vial of drug to provide a means to deliver drug through an injection cannula that is movable between a plurality of positions or through a transfer conduit.
Claims13
An injection device comprising:
- a. a vial holder configured to hold a vial containing a medical fluid;
- b. a canister holder configured to hold a compressed gas canister;
- c. a balloon;
- d. a balloon spike in fluid communication with the balloon and configured to be inserted into a vial positioned in the vial holder and to selectively communicate with the compressed gas canister positioned within the canister holder so that the balloon is inflated within the vial to pressurize medical fluid within the vial;
- e. an injection spike configured to be inserted into a vial positioned in the vial holder;
- f. an injection cannula in fluid communication with the injection spike so that medical fluid pressurized in the vial by inflation of the balloon flows through the injection cannula;
- g. a vial spike holder, where the balloon spike and the injection spike are secured to the vial spike holder and the vile spike holder is configured to move from a first position where the balloon and injection spikes are spaced from the vial and a second position where the balloon and injection spikes are inserted into the vial;
- and
- h. a holder driver including a gear rack connected to the actuation button, a gear rotatably mounted within the housing and a cam secured to the gear, where the gear rack engages and turns the gear as the actuation button moves from the first position to the second position so that the vial spike holder is moved from the first position to the second position by the cam.

A transfer device for transferring medical fluid from a vial comprising:
- a. a vial holder configured to hold a vial containing a medical fluid;
- b. a canister holder configured to hold a compressed gas canister;
- c. a balloon;
- d. a balloon spike in fluid communication with the balloon and configured to be inserted into a vial positioned in the vial holder and to selectively communicate with the compressed gas canister positioned within the canister holder so that the balloon is inflated within the vial to pressurize medical fluid within the vial;
- e. an injection spike configured to be inserted into a vial positioned in the vial holder;
- f. a transfer conduit in fluid communication with the injection spike so that medical fluid pressurized in the vial by inflation of the balloon flows through the transfer conduit;
- g. a vial spike holder, where the balloon spike and the injection spike are secured to the vial spike holder and the vile spike holder is configured to move from a first position where the balloon and injection spikes are spaced from the vial and a second position where the balloon and injection spikes are inserted into the vial;
- and
- h. a holder driver including a gear rack connected to the actuation button, a gear rotatably mounted within the housing and a cam secured to the gear, where the gear rack engages and turns the gear as the actuation button moves from the first position to the second position so that the vial spike holder is moved from the first position to the second position by the cam.
