Abstract

An instrument is disclosed for transferring specified amounts of fluids from a container to a syringe without dependency on eyesight.

Claims

1. An instrument for transferring specified amounts of fluids from a container to a syringe without dependency on eyesight comprising:

a. a frame upon which said syringe may rest; and

b. extraction preparation means slidably attached to said frame to transfer said fluids from said container to said syringe; and

c. stop means secured to said frame to prevent more than a predetermined amount of said fluids to be transferred from said container to said syringe;

d. container holding means slidably attached to said frame and rigidly attached to said extraction preparation means and capable of holding said container;

e. said frame further comprising side guides transversely slidably mounted on said frame, slidably adjustable for holding syriNges of different diameters on said frame;

whereby said instrument is adjustable for syringes of varying lengths and capable of use by persons with differing quality of eyesight, including blind persons.

2. An instrument according to claim 1 wherein said container holding means comprises a trough.

3. An instrument according to claim 1 in which said frame further comprises syringe stop stops rigidly mounted on said frame for restricting lateral movement of said syringe on said frame.

4. An instrument according to claim 2 in which said frame further comprises side guides slidably mounted on said frame, slidably adjustable for holding syringes of different diameters on said frame.

5. An instrument according to claim 1 in which said frame further comprises syringe stop stops rigidly mounted on said frame for restricting lateral movement of said syringe on said frame.

6. An instrument according to claim 4 in which said frame further comprises syring stop stops rigidly mounted on said frame for restricting lateral movement of said syringe on said frame.

7. An instrument according to claim 1 in which said extraction preparation means comprises:

a. a rest for the top of said container; and

b. adjustable sliding means rigidly attached to said rest and slidably attached to said frame whereby the tip of the needle of said syringe may be placed at a pre-determined needle position with respect to said rest, whereby when said top of said container is placed on said rest, said tip of said needle will pierce said top of said container.

8. An instrument according to claim 7 in which said extraction preparation means further comprises alignment means for determining said pre-determined needle position for said needle of said syringe to be placed with respect to said rest whereby when said top of said container is placed in said rest said tip of said needle will pierce said top of said container.

9. An instrument according to claim 8 wherein said alignment means are needle alignment arrows.

10. An instrument according to claim 8 in which said rest further comprises top stop means to restrict said top of said container to a pre-determined top position on said rest whereby when said needle has been placed in said pre-determined needle position and when said top of said container is placed within said rest, said tip of said needle will pierce said top of said container.

11. An instrument according to claim 7 in which said adjustable sliding means comprises:

a slide member, containing openings, rigidly connected to said rest; and

b. a slide piece rigidly mounted on said slide member; and

c. slide guide means within said frame through which said slide piece may slide; and

d. attachment means extending through said openings to attach said slide member to said frame, whereby said attachment means may be loosened for slidable adjusting and tightened for fixing a rigid position.

12. An instrument according to claim 11 wherein said attachment means are screws.

13. An instrument according to claim 1 in which said stop means comprises a plunger stop slidably mounted on said frame restricting the movement of the plunger of said syringe beyond a a pre-determined stopping point on said frame.

14. An instrument according to claim 13 in which said stop means further comprises a plurality of adjustable plunger stops slidably mounted on said frame whereby specified amounts of fluids may be transferred from each of a plurality of containers by the movement of the plunger of said syringe to each of a plurality of pre-determined stopping points determined by each of said plurality of adjustable plunger stops.

15. An instrument according to claim 13 in which said plunger stop may be secured to said frame by use of stop attachment means.

16. An instrument according to claim 15 wherein said stop attachment means comprises a screw.

17. An instrument according to claim 14 where the attachment of said plurality of said adjustable plunger sTops are slidably attached to said frame by adjustable attachment means comprising:

a. hinge means attached to said adjustable plunger stop; and

b. connecting means attached to said hinge means and slidably mounted on said frame.

18. An instrument according to claim 6 in which said adjustable sliding means comprises:

a. a slide member, containing openings, rigidly connected to said rest; and

b. a slide piece rigidly mounted on said slide member; and

c. slide guide means within said frame through which said slide piece may slide; and

d. attachment means extending through said openings to attach said slide member to said frame, whereby said attachement means may be loosened for slidable adjusting and tightened for fixing a rigid position.

19. An instrument according to claim 11 in which said stop means further comprises a plurality of adjustable plunger stops slidably mounted on said frame whereby specified amounts of fluids may be transferred from each of a plurality of containers by the movement of the plunger of said syringe to each of a plurality of pre-determined stopping points determined by each of said plurality of adjustable plunger stops.

20. An instrument according to claim 6 in which said stop means further comprises a plurality of adjustable plunger stops slidably mounted on said frame whereby specified amounts of fluids may be transferred from each of a plurality of containers by the movement of the plunger of said syringe to each of a plurality of pre-determined stopping points determined by each of said plurality of adjustable plunger stops.

21. An instrumnet according to claim 7 in which said rest further comprises a plurality of needle point protectors rigidly connected to said adjustable sliding means located above said rest, whereby when said needle lies in said pre-determined needle position, no requirement exists for said tip of said needle to be touched and sterility may be maintained.
