Abstract

The present invention relates to devices and methods for the filling syringes. One medical apparatus in accordance with the present invention include a body member for releasably holding syringe barrels and an actuator apparatus slidably mounted on the body member to engage syringe plungers to cause the syringe plunger to be retracted. A fluid delivery apparatus is releasably mounted to the body member. The fluid delivery apparatus has an inlet port and a plurality of outlet ports. The inlet port is in fluid communication with each of the plurality of outlet ports. One method for filling a plurality of syringes in accordance with the present invention includes the steps of mounting a plurality a syringes to a syringe holding member and connecting a fluid delivery apparatus to the syringe holding member to mate with each of the tips of the syringe barrels. The method also includes the steps of placing an inlet port of the fluid delivery apparatus in a fluid and moving an actuator apparatus to retract the syringe plungers to cause fluid to enter the syringe barrels.

Claims

1. A medical apparatus for filling a plurality of syringes, each of the syringes having a syringe barrel and a syringe plunger movably disposed within the syringe barrel, the medical apparatus comprising:

a body member for releasably holding the syringe barrels;

an actuator apparatus slidably mounted on the body member to engage the syringe plunger to cause the syringe plunger to be retracted; and

a fluid delivery apparatus releasably mounted to the body member, the fluid delivery apparatus having an inlet port and a plurality of outlet ports, the inlet port in fluid communication with each of the plurality of outlet ports.

2. The medical apparatus of claim 1 wherein the body member includes a plurality of recesses to releasably hold the syringe barrels.

3. The medical apparatus of claim 1 wherein the actuator apparatus include a drive member to engage the plunger heads of the syringe plungers so that the syringe plunger are moved when the actuator apparatus is moved.

5. The medical apparatus of claim 1 further comprising a stop member mounted to the syringe holding member to contact the actuating apparatus in its retracted position.

4. A medical apparatus for filling a plurality of syringes, each of the syringes having a syringe barrel and a syringe plunger movably disposed within the syringe barrel, the medical apparatus comprising:

a syringe holding member having an aperture extending therein;

at least one retaining member mounted to the syringe holding member, the at least one retaining member having a plurality of recesses adapted to receive and hold the syringe barrel of one of the syringes;

an actuating apparatus having a shaft slidably mounted in the aperture of the syringe holding apparatus;

a drive member mounted on the actuating apparatus, the drive member positioned to engage and move the syringe plunger when the actuating member is moved in an upward direction; and

a fluid delivery apparatus releasably mounted to the syringe holding member, the fluid delivery apparatus to transport fluid from an inlet port to a plurality of outlet ports when the syringe plunger is withdrawn.

6. A medical apparatus for filling a plurality of syringes, each of the syringes having a syringe barrel and a syringe plunger movably disposed within the syringe barrel, the medical apparatus comprising:

means for retaining a plurality of syringes;

means, slidably mounted to the retaining means, to engage and move the plunger syringe; and

means for fluidly connecting each of the syringe barrels to a fluid.

7. A method for filling a plurality of syringes with a fluid, each of the syringes having a syringe barrel and a syringe plunger movably disposed within the syringe barrel, the method comprising the steps of:

mounting the plurality a syringes to a syringe holding member;

connecting a fluid connecting member to the syringe holding member to mate with each of the tips of the syringe barrels;

placing an inlet port of the fluid connector member in a fluid; and

moving an actuator apparatus slidably mounted to the syringe holding member to retract the syringe plungers to cause fluid to enter the syringe barrels.

8. The method of claim 7 further comprising the step of moving the actuator apparatus until a desired amount of fluid is filled in the syringe barrel.

9. The method of claim 8 further comprising the step of removing the syringes from the syringe holding member.

10. A medical apparatus for filling a plurality of syringes, each of the syringes having a syringe barrel and a syringe plunger movably disposed within the syringe barrel, the medical apparatus comprising:

a syringe holding apparatus having an aperture extending therein;

a first retaining member, mounted to the syringe holding apparatus, having a plurality of recesses adapted to receive and hold the upper portion of the syringe barrels;

a second retaining member, mounted to the syringe holding apparatus, having a plurality of recesses adapted to receive and hold the lower portion of syringe barrels;

an actuating apparatus having a shaft slidably mounted in the aperture of the syringe holding apparatus;

a drive member mounted on the actuating apparatus, the drive member positioned to engage the syringe plunger;

a hand grip attached to an end of the actuating apparatus; and

a fluid delivery apparatus having releasably mounted to the syringe holding apparatus, the fluid delivery apparatus having an inlet port and a plurality of outlet ports; and

;

a plurality of delivery conduits attached to the inlet port and to each of the plurality of the outlet ports.
