Abstract

This invention relates to adaptors designed to secure an infusion-type pump to an enclosure for delivery of fluids, including medicaments, and the like to a patient in need of such treatment. The enclosure is of a type designed to house a fluid reservoir and conduit extending from the fluid reservoir to the infusion-type pump. The adaptor forms a substantially planar plate having a back face and a front face. The front face includes guides and a support plate to align the pump onto the adaptor. Securing grips are provided to secure the pump onto the adaptor. The adaptor has a back face to reversibly engage the enclosure.

Claims

1. An adaptor to secure an infusion-type pump to an enclosure, the pump having an outer housing and a pump mechanism including tube engaging members for moving fluid through a tubing, wherein the enclosure is designed to house a fluid reservoir and the tubing extending from the reservoir to the infusion-type pump to deliver fluid medicament to a patient, the adaptor comprising:

a body having a front and a back, the front facing in an opposite direction to the back;

a pump mounting mechanism extending from the front of the body to mount the outer housing of the infusion-type pump to the body; and

a back projection extending from the back of the body sized to removably engage the enclosure.

2. An adaptor for use with an infusion-type pump and an enclosure comprising:

a body having a back face, a front face, a top end, a bottom end and two lateral edges;

at least two opposed guide walls positioned substantially perpendicular to and extending from the front face and positioned along the two lateral edges;

a support plate positioned at the top end of the adaptor and spaced from the front face to receive a portion of the infusion-type pump;

at least one securing grip at the bottom end of the adaptor to securably mount the infusion-type pump to the adaptor; and

a mounting device to allow selective mounting of the adaptor to the enclosure.

3. The adaptor of claim 2, wherein the support plate limits movement in two directions.

4. The adaptor of claim 2, wherein the guide walls extend down substantially the entire length of the adaptor.

5. The adaptor of claim 2, wherein the guide walls form guide bars positioned along the lateral edges of the adaptor.

6. The adaptor of claim 2, wherein the back face of the adaptor includes a pole mounting arrangement.

7. The adaptor of claim 2, wherein the back face includes at least one ridge sized for receipt in the enclosure.

8. The adaptor of claim 2, wherein the grip is an L-shaped clip.

9. The adaptor of claim 2, further comprising a second securing grip at the bottom end of the adaptor.

10. The adaptor of claim 9, wherein the securing grips extend from the bottom of the adaptor.

11. The adaptor of claim 2, wherein the mounting device includes the body defining a projection receiving slot.

12. The adaptor of claim 2, wherein a release bar extends from the front face of the support plate and wherein pressure applied to the release bar repositions the securing grip.

13. An infusion system comprising:

an infusion-type pump having an outer housing including a keyboard and a pump mechanism including tube engaging members for moving fluid through a tubing;

a substantially rigid enclosure sized to house a fluid reservoir and the tubing extending from the fluid reservoir to the infusion-type pump, the enclosure defining an opening, and

an adaptor securing the outer housing of the infusion-type pump to the enclosure at the opening so as to close the opening, wherein the keyboard is exposed for access by an operator when the enclosure receives the fluid reservoir and the tubing and the adapter secures the pump to the enclosure.

14. The system of claim 13, wherein the pump further comprises a control module and a pressure plate.

15. A method for assembling an infusion system comprising the steps of:

mounting an outer housing of an infusion-type pump onto a front of an adaptor;

placing a fluid reservoir and a tubing extending from the fluid reservoir through an opening into an enclosure wherein the tubing extends from the fluid reservoir to the infusion-type pump; and

after placing the fluid reservoir and the tubing into the enclosure, securing a back of the adaptor to the enclosure to close the opening, the front of the adaptor facing in an opposite direction to the back.

16. The method of claim 15, wherein the pump comprises a control module and a pressure plate.

17. The method of claim 15, wherein the adaptor comprises:

a substantially planar plate having a back face and a front face, the front face having guide walls and a support plate to position an infusion-type pump to the adaptor, at least one grip to securably mount the infusion-type pump to the adaptor and a locking mechanism to reversibly position the adaptor onto the enclosure.

18. The method of claim 15, wherein the securing step further comprises the steps of guiding the infusion-type pump onto the adaptor, positioning a portion of the pump under a support plate of the adaptor and engaging the pump with securing grips positioned on the adaptor.

19. The method of claim 15, further comprising the step of unsecuring the adaptor from the enclosure.

20. A method for securing a pump to an enclosure designed to house a fluid reservoir and a tubing extending from the fluid reservoir to the infusion-type pump, the pump having an outer housing and a pump mechanism including tube engaging members for moving fluid through the tubing, comprising the steps of:

securing the outer housing of the infusion-type pump to an adaptor;

mating the adaptor onto the enclosure wherein the enclosure houses a fluid reservoir and the tubing extending from the fluid reservoir to the infusion-type pump; and

locking the adaptor to the enclosure to secure the adaptor onto the enclosure.

21. The method of claim 20, further comprising the step of unlocking the adaptor from the enclosure.
