ABSTRACT:
This invention pertains to improvements in an intermixing syringe with isolation storage. The outer housing is similar to the conventional syringe and has a relatively constant diameter barrel with a hub at one end and wing portions at the other. A rigid insert is provided at the forward end of the housing, said insert made an air-tight fit by an O-ring. This insert includes a one-way valve to inhibit flow into the housing, a filter to remove all unwanted particles, a plurality of small passageways and a cone-like projection used to break a glass ampule in which the powder is stored prior to breaking and intermixing. A tubular member is slidably carried in this housing and contains the diluent. A plunger end closes this tubular member and a through passageway is closed at its lower end by a one-way valve that is closed when the plunger end is moved forwardly. A short passageway is also provided in the plunger end and provides flow communication for air from the outside into the tubular member. This passageway is closed by another one-way valve that is closed to the flow of diluent but open to an inflow of air when needed during the transfer of diluent to the housing.
