Abstract

A syringe-assist device including a housing portion, an actuator portion, and a syringe-supporting member. The housing portion includes body defining an axial passage. The actuator portion is connected to and is partially disposed within the axial passage of the body. The syringe-supporting member is movably-disposed within the axial passage. The syringe-supporting member fluidly separates the axial passage into a first, proximal passage portion and a second, distal passage portion. The actuator portion is movably-disposed within the second, distal passage portion of the axial passage. The syringe-supporting member defines a fluid-flow passage that fluidly-connects the first, proximal passage portion of the axial passage to the second, distal passage portion of the axial passage. A method is also disclosed.

Claims

1. A syringe-assist device, comprising:

a housing portion that defines an axial passage;

an actuator portion partially disposed within the axial passage of the housing portion, wherein the actuator portion includes;

an actuator member having a proximal end and a distal end,

a head member connected to the proximal end of the actuator member, and

a cap member connected to the distal end of the actuator member, wherein the cap member includes an outer side surface and an inner side surface, wherein the inner side surface defines the cap member to include an inner diameter that is slightly greater than a body diameter defined by an outer surface of the housing portion, wherein the cap member includes a first locking hole and a second locking hole; and

a syringe-supporting member movably-disposed within the axial passage, wherein the syringe-supporting member fluidly separates the axial passage into a first passage portion and a second passage portion, wherein the actuator portion is movably-disposed within the second passage portion of the axial passage, wherein syringe-supporting member defines a fluid-flow passage that fluidly-connects the first passage portion of the axial passage to the second passage portion of the axial passage.

2. The syringe-assist device according to claim 1, wherein the housing portion is a tube-shaped body having a proximal end portion, a distal end portion and a side portion extending between the proximal end portion and the distal end portion, wherein each of the proximal end portion, the distal end portion and the side portion are defined by an outer surface and an inner surface such that the tube-shaped housing portion is defined by a thickness extending between the outer surface and the inner surface.

3. The syringe-assist device according to claim 2, wherein the inner surface defines the axial passage, wherein the axial passage extends through the tube-shaped housing portion along a central axis between the proximal end portion and the distal end portion of the tube-shaped housing portion, wherein the inner surface defines the axial passage to form an axial passage diameter, wherein the outer surface defines the tube-shaped housing portion to form a body diameter.

4. The syringe-assist device according to claim 2, wherein the tube-shaped housing portion forms a first opening and a second opening each extending through the thickness of the tube-shaped housing portion, wherein the first opening is formed in the distal end portion of the tube-shaped housing portion and is axially-aligned with the central axis, wherein the second opening is formed in the side portion of the tube-shaped body.

5. The syringe-assist device according to claim 4, wherein the second opening extends along a portion of a length of the tube-shaped body, wherein the second opening is approximately equal to but slightly greater than half of a circumference of the tube-shaped body.

6. The syringe-assist device according to claim 1, wherein the syringe-supporting member includes a handle extending from the syringe-supporting member.

7. The syringe-assist device according to claim 1, wherein the syringe-supporting member includes a diameter that is slightly less than an axial passage diameter formed by the axial passage of the tube-shaped housing portion.

8. The syringe-assist device according to claim 1, further comprising:

a base member connected to a proximal end portion of the housing portion.

9. The syringe-assist device according to claim 1, wherein a first portion of the actuator portion is movably-disposed within the second passage portion of the axial passage, wherein a second portion of the actuator portion is arranged exterior of the housing portion.

10. The syringe-assist device according to claim 1, wherein the actuator member includes a piston rod that is movably-disposed within a cylinder.

11. The syringe-assist device according to claim 10, wherein the piston rod contains a gas.

12. The syringe-assist device according to claim 1, wherein the head member includes a diameter that is slightly less than a diameter of the axial passage of the housing portion.

13. The syringe-assist device according to claim 1, wherein the first locking hole and the second locking hole are arranged in a diametrically-opposing relationship.

14. The syringe-assist device according to claim 1, wherein each of the first locking hole and the second locking hole include an L-shaped geometry.

15. The syringe-assist device according to claim 14, further comprising:

a first flange and a second flange located at a distal end portion of the housing , wherein when the cap member is selectively-arranged upon the distal end portion of the housing such that the first flange and the second flange are respectively-arranged within the first locking hole and the second locking hole the cap member is selectively-coupled to the distal end portion of the housing.

16. A method, comprising the steps of:

providing a syringe-assist device according to claim 1;

removably-disposing a container within the first passage portion of the axial passage such that the container is in fluid communication with a proximal opening of the fluid-flow passage;

removably-disposing a syringe within the second passage portion of the axial passage such that the syringe is in fluid communication with a distal opening of the fluid-flow passage; and

actuating the actuator portion for discharging a fluid contained within the syringe through the fluid-flow passage and into the container.

17. The method according to claim 16, wherein the removably-disposing the container step includes:

arranging a lower end surface of the container adjacent a proximal end portion of the tube-shaped housing portion; and

arranging a proximal end surface of the syringe-supporting member adjacent an upper end surface of the container.

18. The method according to claim 16, wherein the removably-disposing the syringe step includes:

disposing a distal tip of a wheel filter attached to a proximal end of the syringe in the fluid-flow passage of the syringe-supporting member.

19. The method according to claim 16, wherein the actuating the actuator portion step includes:

applying a pushing force to the distal end of the actuator portion.

20. The method according to claim 19, wherein the actuator member includes a piston rod movably-disposed within a cylinder and wherein the applied pushing force results in the piston rod engaging with a plunger of the syringe and the piston rod retracting into the cylinder.

21. The method according to claim 19, further comprising the steps of:

twisting the distal end of the actuator portion for locking the distal end of the actuator portion to a distal end portion of the housing portion.

22. The method according to claim 21, further comprising the steps of:

extending the piston rod from the cylinder and toward the plunger of the syringe for discharging the fluid contained within the syringe through the fluid-flow passage and into the container.
