Abstract

A delivery device for delivering a medication to a patient includes a catheter with a catheter insertion mechanism, a housing, and a base with a surface for supporting a pump mechanism. A noise dampening member in or on the device inhibits noise and vibrations from the pump mechanism from transferring through the base and housing. The noise dampening member can be an elastomer that is coated on or adhered to the base. The noise dampening member can be molded in or on the base in a suitable location to dampen noise produced by the mechanical component. The noise dampening member can be between the base and the mechanical component or spaced from the mechanical component. The noise dampening member can be molded in a recessed area formed in the base and can have a top face that is recessed, aligned with or project from the top face of the base.

First claim

The invention claimed is:

1. A delivery device, comprising:
a housing;
a base coupled to said housing to form an enclosure between said housing and said base, a pump mechanism having at least one component, said base configured for supporting said at least one component of said pump mechanism within said enclosure, a cannula configured for delivering a substance to a patient, said cannula connected to said pump mechanism, and a reservoir for the substance to be delivered to the patient, and said reservoir connected to said pump mechanism;
said base having a recess defining an opening extending through said base between a top face and a bottom face configured for contacting a patient, at least one noise dampening member oriented in said recess of said base within said enclosure to dampen noise produced by said at least one component of said pump mechanism.

2. The device according to claim 1 , wherein said delivery device includes a catheter and said at least one noise dampening member is an elastomeric material, and where said at least one component of said pump mechanism is mounted over said elastomeric material.

3. The device according to claim 1 , wherein said at least one noise dampening member is a thermoplastic elastomeric material attached or adhered to said base in said recess, and where said at least one dampening member has a top face flush with the top face of said base.

4. The device according to claim 1 , wherein said at least one noise dampening member is a thermoplastic elastomeric material is molded directly to a surface of said base in said recess within a boundary of said base, and said noise dampening member has a top face projecting from the top face of the base.

5. The device according to claim 1 , wherein said at least one component of said pump mechanism is a gear box or electric motor of said pump mechanism.

6. The device according to claim 1 , wherein said at least one noise dampening member is spaced from said pump mechanism.

7. The device according to claim 1 , wherein said at least one noise dampening member is a separate member attached to said base by bonding or by an adhesive.

8. The device according to claim 1 , wherein said top face is coupled to said housing, and where said at bast one noise dampening member has a top face spaced from a top face of said base to define a recessed area in said top face to accommodate said pump mechanism, said at least one noise dampening member having a bottom face flush with said bottom face of said base.

9. The device according to claim 1 , further comprising a plurality of said noise dampening members, wherein at least one dampening member is formed on said base.

10. The device according to claim 1 , wherein said at least one noise dampening member is positioned in said recess of said base, said at least one noise dampening member having a bottom face flush with said bottom face of said base, wherein said at least one noise dampening member is oriented between said base and said pump mechanism, and said bottom face of said at least one noise dampening member has a plurality of tabs coupled to said base, or said base includes a plurality of tabs extending from said top face of said base coupled to said at least one noise dampening member.

11. The device according to claim 1 , wherein base includes a support extending from a top face of said base, said at least one component coupled to said support, said at least one noise dampening member spaced from said pump mechanism, and wherein said noise dampening member is a separate member attached to said base by bonding or by an adhesive.

12. A delivery device comprising:
a housing;
a pump mechanism for delivering a substance to a patient, a base coupled to said housing and defining an enclosure between said base and said housing for accommodating said pump mechanism within said enclosure for delivering a substance to the patient, said base having a top face supporting said pump mechanism, and a bottom face, a recess defining an opening extending between said top face and said bottom face; and
at least one noise dampening member formed in said recess of said base within said enclosure formed by said base and said housing, and where said pump mechanism is coupled to said top face of said base over said at least one noise dampening member.

13. The device according to claim 12 , wherein said at least one noise dampening member is a thermoplastic elastomeric material.

14. The device according to claim 12 , wherein said delivery device is a catheter infusion pump comprising a catheter connected to a pump mechanism for delivering the substance to the patient.

15. The device according to claim 12 , wherein said at least one noise dampening member is formed in said recess in said base and adhered directly to a surface of said base, and where said at least one noise dampening member projects into said enclosure and is spaced from said pump mechanism.

16. The device of claim 12 , wherein said at least one noise dampening member has a dimension and configuration complementing at least one component of the pump mechanism and is oriented between said base and said pump mechanism.

17. The device of claim 16 , wherein said at least one component of said pump mechanism is a gear box or electric motor of said pump mechanism.

18. The device of 16 , wherein said at least one noise dampening member is oriented within a boundary of said base.

19. The device of claim 12 , wherein said top face of said base is coupled to said housing to define said enclosure, and where said top face has a plurality of said noise dampening members in said base or on a top face of said base, and where at least one noise dampening member is spaced from said pump mechanism.

20. The device of claim 12 , wherein said top face of said base is coupled to said housing and where said recess s in said top face and where said at least one noise dampening member is formed in said recess.

21. The device of claim 20 , wherein said at least one noise dampening member has a top face spaced outwardly from said top face of the base.

22. The device of claim 12 , wherein said at least one noise dampening member is formed as a separate member and is attached to said top face of said base by bonding or by an adhesive.

23. The device of claim 22 , wherein said a least one noise dampening member has a top side and a bottom side for mating with the base, and where said bottom side has an adhesive layer for attaching said at least one noise dampening member to said base.
