Abstract

A mounting clip is provided for removable mounting of a medication infusion pump of the type used to deliver a selected medication such as insulin to a patient. In the preferred form, the mounting clip comprises a belt clip with a pair of pivotally interconnected and spring-loaded legs adapted for mounting onto a belt or other item of clothing worn by a patient. One leg of the belt clip includes a dovetail key for slide-fit reception into a mating dovetail slot formed in the housing of a medication infusion pump. A detent button is carried on the belt clip at the distal end of a spring arm for snap-fit reception into a detent seat formed in the pump housing, to lock the pump onto the belt clip. The spring arm is manually accessible to permit fingertip retraction of the detent button from the seat, and thereby permit easy sliding removal of the pump housing from the belt clip.

Claims

1. A mounting clip for removably supporting a medication infusion pump on a patient, said mounting clip comprising:

a mounting plate having slide-fit means including a dovetail key formed on said mounting plate for slide-on mounting and slide-off removal of the pump with respect to said plate, and detent means for locking the pump on said plate when the pump is slidably mounted thereon;

said detent means being manually releasible to permit slide-off removal of the pump from said plate; and

means for mounting said plate onto a patient.

2. The mounting clip of claim 1 wherein said detent means comprises a spring arm carried by said plate and having a detent buttom generally at a distal end of said spring arm.

3. The mounting clip of claim 2 wherein said plate and spring arm are integrally formed.

4. The mounting clip of claim 2 wherein said plate and spring arm are formed from molded plastic.

5. The mounting clip of claim 1 wherein said mounting means is adapted for removable mounting of said plate onto a selected article of clothing worn by the patient.

6. The mounting clip of claim 1 wherein said mounting means comprises a leg member pivotally interconnected to said mounting plate whereby said mounting plate and leg member cooperatively define a belt clip for removable mounting onto a belt worn by the patient.

7. The mounting clip of claim 1 wherein said detent means includes a spring arm defining a detent member thereon, said spring arm further defining an edge surface protruding outwardly beyond the pump when said pump is mounted and locked onto said mounting plate, said edge surface being manually accessible to retract said spring arm relative to the pump to manually release said detent means.

8. The mounting clip of claim 7 wherein said edge surface of said spring arm is a serrated edge.

9. A mounting clip for removably supporting a medication infusion pump on a patient, said mounting clip comprising:

a mounting plate having a dovetail key thereon for slide-fit reception into a dovetail slot formed in a housing of the medication infusion pump;

said mounting plate further including a spring arm having a detent button thereon for snap-fit reception into a detent seat formed in the pump housing when said dovetail key is substantially fully received into the dovetail slot, whereby the pump housing is slidably mountable onto said mounting plate and locked thereon upon snap-fit reception of said detent button into the detent seat, said spring arm being positioned for manual retraction relative to the pump housing to retract said detent button from the detent seat and thereby permit slide-off removal of the pump housing from said mounting plate; and

means for mounting said plate onto an article of clothing worn by a patient.

10. The mounting clip of claim 9 wherein said plate and spring arm are formed from molded plastic.

11. The mounting clip of claim 9 wherein said mounting means comprises a leg member pivotally interconnected to said mounting plate whereby said mounting plate and leg member cooperatively define a belt clip for removable mounting onto a belt worn by the patient.

12. The mounting clip of claim 9 wherein said spring arm further defines an edge surface protruding outwardly beyond the pump when said pump is mounted and locked onto said mounting plate, said edge surface being manually accessible to retract said spring arm relative to the pump to manually release said detent means.

13. In combination:

a medication infusion pump for delivery of a selected medication to a patient, said pump including a pump housing; and

a mounting clip for mounting onto the patient and including a mounting plate;

said mounting plate and pump housing defining interengageable slide-fit means including a dovetail key formed on one of said pump housing and mounting plate, and a matingly shaped dovetail slot formed on the other of said pump housing and mounting plate, said slide-fit means being for slide-on mounting and slide-off removal of the pump housing with respect to said mounting plate;

said mounting plate and pump housing further defining interengageable detent means for snap-fit locking of the pump housing onto said mounting plate when said slide-fit means is substantially fully engaged;

said detent means being manually releasible by the patient to unlock the pump housing from said mounting plate and permit slide-off removal therefrom.

14. The combination of claim 13 wherein said detent means comprises a detent button formed on one of said pump housing and mounting plate, and a mating detent recess formed on the other of said pump housing and mounting plate.

15. A mounting clip for removably supporting a medication infusion pump on a patient, said mounting clip comprising:

a mounting plate having slide-fit means for slide-on mounting and slide-off removal of the pump with respect to said plate, and detent means for locking the pump on said plate when the pump is slidably mounted thereon;

said detent means beging manually releasible to permit slide-off removal of the pump from said plate; and

means for mounting said plate onto a patient;

said detent means on said mounting plate comprising a spring arm having a detent member thereon, said spring arm defining an edge surface protruding outwardly beyond the pump housing when said pump housing is mounted and locked onto said mounting plate, said edge surface being manually accessible to retract said spring arm relative to the pump housing to manually release said detent means.

16. The combination of claim 15 wherein said edge surface of said spring arm is a serrated edge.

17. A mounting clip for removably supporting a medication infusion pump on a patient, said mounting clip comprising:

a mounting plate having slide-fit means for slide-on mounting and slide-off removal of the pump with respect to said plate, and detent means for locking the pump on said plate when the pump is slidably mounted thereon;

said detent means beging manually releasible to permit slide-off removal of the pump from said plate; and

means for mounting said plate onto a patient;

said slide-fit means comprising an open-ended dovetail slot formed in the pump housing and a mating dovetail key formed on said mounting plate, and wherein said detent means comprises a detent recess formed in said pump housing at a position generally in-line with said dovetail slot and a spring arm forming a portion of said mounting plate and having a detent button for snap-fit reception into said detent recess.

18. The combination of claim 17 wherein said pump housing comprises at least two housing members assembled to each other by at least one mounting screw, said mounting screw being received in a counterbore formed in one of the housing members, said counterbore defining said detent recess.

19. A mounting clip for removably supporting a medication infusion pump on a patient, said mounting clip comprising:

a mounting plate having slide-fit means for slide-on mounting and slide-off removal of the pump with respect to said plate, and detent means for locking the pump on said plate when the plate is slidably mounted thereon;

said detent means being manually releasible to permit slide-off removal of the pump from said plate; and

means for mounting said plate onto a patient;

said detent means including a spring arm defining a detent member thereon, said spring arm further defining an edge surface protruding outwardly beyond the pump when said pump is mounted and locked onto said mounting plate, said edge surface being manually accessible to retract said spring arm relative to the pump to manually release said detent means.

20. The mounting clip of claim 19 wherein said edge surface of said spring arm is a serrated edge.
