Abstract

The invention relates to a dispensing device for simultaneously dispensing fluid from at least two fluid containers fitted with plungers, wherein the device includes an actuating device having at least two output elements, a push element able to displace the output elements, a force element that acts on the push element in the direction of the fluid containers, and a brake element which acts on the push element and can be manually modified to cancel the effect of the force element.

Claims

1. A generally pistol-shaped delivery device for simultaneously delivering fluids from two fluid containers equipped with plungers, comprising a grip, and an actuator, the actuator comprising two output elements, a push element which moves said output elements, a force element which acts on said push element in the direction of said fluid containers, and a brake element which cancels out the effect of said force element unless said brake element is modified manually.

2. The delivery device of claim 1, wherein said force element is a spring.

3. The delivery device of claim 1, wherein said brake element comprises a spring acting on a braking surface area.

4. The delivery device of claim 1, wherein said fluid containers are syringe bodies.

5. The delivery device of claim 4, wherein said syringe bodies are arranged in parallel.

6. The delivery device of claim 1, wherein said delivery device comprises a hollow carrier and a grip.

7. The delivery device of claim 6, wherein a spindle supporting a brake lever is generally and openly arranged between said grip and said hollow carrier.

8. The delivery device of claim 7, wherein said brake lever comprises a long component and a short component, whereby said long component and said short component form an angle with each other, and support a braking surface area.

9. The delivery device of claim 8, wherein a locking mechanism prevents accidental actuation of said brake lever.

10. The delivery device of claim 9, wherein said brake element comprises said brake lever, said spindle, said locking mechanism, said braking surface area, and a spring, whereby when said long component of said brake lever is urged away from said grip by the force of said spring, said braking surface area acts on said push element, and cancels out the effect of said force element.

11. The delivery device of claim 1, wherein said fluid containers are immovably held in place.

12. The delivery device of claim 1, further comprising a cannula fitted into an outlet opening of each fluid container, whereby mixing of the two fluids does not occur until they are at a site to which they are applied.

13. The delivery device of claim 12, further comprising a supporting housing which contains the cannulas.

14. The delivery device of claim 12, further comprising a squirter, whereby the two fluids to be mixed are squirted onto a surface area.

15. The delivery device of claim 1, wherein said push element comprises a slider and a T-shaped plate, arranged at a distal end of said slider, whereby said T-shaped plate contacts a distal end of said output elements.

16. The delivery device of claim 15, wherein a braking surface area in contact with said slider cancels out the effect of said force element.

17. A method of using a delivery device for simultaneously delivering fluids from two fluid containers equipped with plungers, comprising:

providing the two fluid containers equipped with plungers, each container holding a fluid to be mixed;

providing the delivery device, the delivery device being generally pistol-shaped, and comprising a grip and an actuator, the actuator comprising two output elements, a push element which moves said output elements, a force element which acts on said push element in the direction of said fluid containers, and a brake element acting on said push element, which cancels out the effect of said force element unless said brake element is modified manually;

attaching said fluid containers to said delivery device so that said plungers are in contact with said output elements;

providing a surface to apply the fluids to; and

modifying said brake element, so that the effect of said force element is not cancelled, whereby said actuator forces fluid from an output end of the two fluid containers onto the surface.

18. The method of claim 17, whereby said braking element comprises a braking surface area which acts on said actuator to cancel out the effects of said force element, a brake lever, which carries said braking surface area, and a spring, attached to said brake lever, whereby the force of said spring holds said brake lever in a position where said braking surface area cancels out the effect of said force element.

19. The method of claim 17, wherein said force element is a spring.

20. The method of claim 17, wherein said push element comprises a slider and a generally T-shaped plate, arranged at a distal end of said slider, whereby said generally T-shaped plate contacts a distal end of said output elements.

21. A generally pistol-shaped delivery device for simultaneously delivering fluids from two fluid containers equipped with plungers, comprising a grip, and a generally hollow carrier, the carrier comprising two plunger rods, a slider, which moves said plunger rods, a spring which acts on said slider in the direction of said fluid containers, and a braking surface area acting on said slider, which cancels out the effect of said spring unless said brake braking surface area is modified manually.

22. The delivery device of claim 21, wherein said slider comprises a generally T-shaped plate arranged at a distal end of said slider, whereby said generally T-shaped plate contacts a distal end of said plunger rods.

23. The delivery device of claim 21, wherein, said generally hollow carrier is located on a generally central longitudinal axis.

24. The delivery device of claim 23, wherein said two fluid containers are each located on a longitudinal axis generally parallel to said generally central longitudinal axis of said generally hollow carrier.

25. The delivery device of claim 23, wherein said grip is located on a generally central longitudinal axis generally transverse to said generally central longitudinal axis of said generally hollow carrier.

26. The delivery device of claim 21, wherein said grip and said generally hollow carrier are generally perpendicular.
