Abstract

Fluid storage apparatus for medical use is described that includes a length of tubing having a first end and a second end. A first sealable connector portion is provided at the first end and a second sealable connector portion is provided at the second end. The volume of fluid that can be stored within the apparatus is known and an infusate or therapeutic agent is contained within the apparatus. In this manner, a known volume of therapeutic agent can be infused to a patient. The use in neurosurgical applications is described.

Claims

1. Fluid storage apparatus for medical use, the apparatus comprising a length of tubing having a first end and a second end, a first sealable connector portion being provided at the first end and a second sealable connector portion being provided at the second end, wherein the volume of fluid that can be stored within the apparatus is known and in that an infusate is contained within the apparatus.

2. Apparatus according to claim 1, wherein one or both of the first and second sealable connector portions comprise a self-sealing connector portion.

3. Apparatus according to claim 2, wherein each self-sealing connector portion includes a septum.

4. Apparatus according to claim 2, wherein each self-sealing connector portion includes a twist lock member.

5. An apparatus according to claim 1, wherein the internal volume of the apparatus is selected to be equal to the volume of infusate to be delivered to a patient.

6. An apparatus according to claim 1, wherein the apparatus comprises a marking or label that indicates the internal volume of the apparatus.

7. An apparatus according to claim 1, wherein the length of tubing comprises flexible plastic tubing.

8. An apparatus according to claim 1, wherein the volume of infusate that can be stored within the apparatus is less than 10 ml.

9. An apparatus according to claim 1, wherein the infusate comprises a cytotoxic agent or a neurotrophic factor.

10. An apparatus according to claim 1, wherein the internal diameter of the length of tubing is less than 2 mm.

11. Fluid delivery apparatus, comprising an outlet tube from a fluid delivery device, a fluid storage apparatus according to claim 1 and an implantable catheter, wherein the outlet tube is connectable to the implantable catheter via the fluid storage apparatus.

12. Fluid delivery apparatus according to claim 11, wherein the cross-sectional area of the lumens of the outlet tube, the fluid storage apparatus and the implantable catheter are substantially equal.

13. A fluid storage kit comprising a plurality of fluid storage apparatus according to claim 1, wherein the plurality of fluid storage apparatus includes fluid storage apparatus storing different known volumes of infusate.

14. A method for storing a preset volume of fluid comprising a required dosage of therapeutic agent, the method comprising the steps of selecting a length of tubing having a volume equal to the preset volume of fluid, loading the fluid into the length of tubing and sealing each end of the length of tubing.

15. A method for dispensing a predetermined dosage of therapeutic agent to a subject, comprising the step of connecting a fluid dispensing pump to an implanted catheter via one or more fluid delivery tubes, wherein the method comprises the step of locating a storage tube in the fluid path from the pump to the catheter, the storage tube containing a known volume of therapeutic agent for delivery to the subject.
