Multi-compartment apparatus for in-situ mixing of a plurality of components before use |
| 摘要 |
A multi-compartment syringe apparatus (500) for in-situ mixing of a plurality of products before use, the apparatus comprising: a tube; a hollowed flexible plunger (530); a one way filter piston (514), connected to the plunger (530), the piston confining a first compartment (502) at a side of a needle (540) of the apparatus, and a second compartment (510) at a side of the plunger, wherein the filter allowing passage of content only form the first compartment to the second compartment (510); a first product (506), stored in the first compartment (502); a second product (508), stored in a first breakable container (504) disposed in the plunger (530); thereby the second product (508) mixes with the first product (506); and the mixed products are then pushed out of the apparatus, through the needle (540). |

1. A multi-compartment syringe apparatus for in-situ mixing of a plurality of products before use, the apparatus comprising:
a tube; a hollowed flexible plunger; a sealed breakable first container disposed in said plunger; a one way filter piston connected to said plunger, said piston confining a first compartment at a side of a needle of said apparatus, and a second compartment at a side of said plunger, wherein said filter allowing passage of content only from said second compartment to said first compartment, while avoiding passage of pieces of said breakable first container from said second compartment to said first compartment; a first product stored in said first compartment; a second product stored in said first sealed breakable container, thereby upon blocking said needle, breaking said first sealed breakable container and pulling said plunger out of said tube, said second product enters through said filter piston into said first compartment and mixes with said first product, andupon unblocking said needle and pressing said plunger into said tube, said filter piston pushing the mixed products out of said apparatus, through said needle (540). |
