Abstract

A first portable medical device is adapted for use in an interlocking system for interlocking the first medical device to a second medical device. The first device includes a housing having opposite sides, a selective element, a blocking element, and a clamp mechanism. At least one of the opposite sides includes a matable element to detachably attach a second medical device. The selective element restricts the attachment of the second device to only one side of the first device. The blocking element prevents a third medical device from attaching to the first and second devices once the first and second devices are attached. The clamp restricts the attachment of the second device to only one side of the first device when the clamp is attached to a support member. The clamp permits slide-ratcheting axial movement of a clamp shaft.

Claims

1. A system for interlocking a plurality of portable medical devices in a side-by-side relationship, the system comprising:

the plurality of portable medical devices including a first medical device and a second medical device;

the first medical device including a housing having opposite sides, at least one of the opposite sides including a matable element;

the second medical device including a housing having opposite sides, at least one of the opposite sides of the housing of the second medical device including a matable element for detachably interconnecting to the matable element on the first medical device housing and attaching the first and second medical devices;

wherein at least one of the medical devices includes a blocking means for preventing a third medical device from attaching to either one of the first medical device and the second medical device once the first medical device and the second medical device are attached; and

wherein the at least one of the medical devices is provided with only a single matable element, constituting the blocking means.

2. The system of claim 1, wherein the first medical device is provided with two matable elements, a first matable element being located on one of the first medical device housing sides and a second matable element being located on the first medical device housing opposite side.

3. The system of claim 2, wherein the blocking means includes a blocking element associated with the first medical device which blocks attachment of a third medical device to the first medical device once the first and second medical devices are attached.

4. The system of claim 1, wherein at least one of the medical devices includes a latch element which detachably locks the first and second medical devices together once the first and second medical devices are attached.

5. The system of claim 4, wherein a release element is operatively associated with the latch element, the release element permitting a user to selectively disengage the latch element.

6. The system of claim 4, wherein the first medical device includes the latch element, the first medical device is provided with two matable elements where one matable element is located on each of the first medical device housing opposite sides, and wherein the blocking means includes the latch element which extends

from

the first medical housing side that is not adjacent the attached second medical device, the latch element being secured in a position which prevents a third medical device from being added to the first medical device once the first and second medical devices are attached.

7. The system of claim 1, wherein the first and second medical devices each include a transceiver, the transceivers being aligned for communication between the medical devices once the first and second medical devices are attached.

8. A system in accordance with claim 1, wherein the matable element on the first medical device includes a ramped portion allowing the matable element on the second medical device to mate therewith when said matable elements are not precisely aligned.

9. A system in accordance with claim 1, wherein the matable element on the second medical device includes a tapered portion allowing the matable element on the first medical device to mate therewith when said matable elements are not precisely aligned.

10. A system in accordance with claim 1, wherein matable elements are corresponding male T-slides and female T-slots.
