Abstract
Abstract An EKG monitor/recorder and defibrillator which are contained in separate housings are mechanically interconnected by a tongue member located on an exterior surface of the housing of the EKG monitor/recorder and a groove member located on an exterior surface of the housing of the defibrillator. The groove member receives the tongue member with a translative, sliding fit to also permit easy disconnection and separation of the EKG monitor/recorder and the defibrillator. Electrical interconnection between the EKG monitor/recorder and the defibrillator is afforded by a pair of novel electrical slide connectors respectively located in the exterior surfaces of the housings in proximity to the tongue and groove members, with each electrical slide connector including a plurality of spaced-apart leaf spring contacts which, in assembly, extend parallel to the direction of translative movement of the EKG monitor/recorder and defibrillator housings. Circuitry is provided within the EKG monitor/recorder and defibrillator for providing EKG monitoring through paddle electrodes of the defibrillator by coupling the paddle electrodes to the EKG monitor/recorder through the pair of electrical slide connectors.

Claim 1
Independent Claim
273 words
A portable electronic physiological instrument including: a. separable first and second components, said first component comprising an EKG monitor having a pair of signal inputs, and said second component comprising a defibrillator having a pair of paddle electrodes, wherein said components have separate housings, each of said housings having a plurality of exterior surfaces; b. tongue member means coupled to the housing of one of said first and second components and extending from one of said plurality of exterior surfaces thereof; c. groove member means coupled to the housing of the other of said first and second components and extending from one of said plurality of exterior surfaces thereof, said groove member means receiving said tongue member means with a translative, sliding fit to provide mechanical interconnection between said first and second components; d. first and second electrical slide connectors located, respectively, in the housings of said first and second components in proximity to said tongue member means and said groove member means, said first and second electrical slide connectors each including first and second electrical contacts, said first and second electrical contacts of said first and said second electrical slide connectors contacting each other upon said tongue member means being received in said groove member means to provide electrical interconnection between said first and second components; and e. said first component further comprising means for electrically connecting said pair of signal inputs to said first and second contacts of said first electrical slide connector, and said second component further comprising means for electrically connecting said pair of paddle electrodes to said first and second electrical contacts of said second electrical slide connector.
Claim 2
Dependent Claim
273 words
A portable electronic physiological instrument including: a. separable first and second components, said first component comprising an EKG monitor having a pair of signal inputs, and said second component comprising a defibrillator having a pair of paddle electrodes, wherein said components have separate housings, each of said housings having a plurality of exterior surfaces; b. tongue member means coupled to the housing of one of said first and second components and extending from one of said plurality of exterior surfaces thereof; c. groove member means coupled to the housing of the other of said first and second components and extending from one of said plurality of exterior surfaces thereof, said groove member means receiving said tongue member means with a translative, sliding fit to provide mechanical interconnection between said first and second components; d. first and second electrical slide connectors located, respectively, in the housings of said first and second components in proximity to said tongue member means and said groove member means, said first and second electrical slide connectors each including first and second electrical contacts, said first and second electrical contacts of said first and said second electrical slide connectors contacting each other upon said tongue member means being received in said groove member means to provide electrical interconnection between said first and second components; and e. said first component further comprising means for electrically connecting said pair of signal inputs to said first and second contacts of said first electrical slide connector, and said second component further comprising means for electrically connecting said pair of paddle electrodes to said first and second electrical contacts of said second electrical slide connector.
Claim 3
Dependent Claim
53 words
An instrument as recited in claim 1, wherein said tongue member means is formed as an integral part of the housing of one of said first and second components, and wherein said groove member means is formed as an integral part of the housing of the other of said first and second components.
Claim 4
Dependent Claim
174 words
An instrument as recited in claim 1, wherein said tongue member means includes a tongue member extending substantially perpendicularly from a first one of said plurality of exterior surfaces of the housing of one of said first and second components, said tongue member having a side surface substantially parallel to said first one surface, and upper and lower surfaces extending from said side surface to said first one surface, said tongue member defining first and second opposing, substantially aligned tongues aligned on said upper and said lower surfaces thereof; and, wherein said groove member means includes a first hook-like member extending substantially perpendicularly from a second one of said plurality of exterior surfaces of the housing of said other of said first and second components and defining a first groove extending along and adjacent said second one surface for receiving said first tongue, and a second hook-like member extending substantially perpendicularly from said second one surface and defining a second groove extending along and adjacent said second one surface for receiving said second tongue.
Claim 5
Dependent Claim
69 words
An instrument as recited in claim 3, wherein said groove member means includes a side surface extending between said first and said second hook-like members, said side surface of said groove member means being complementary to said side surface of said tongue member so that said respective side surfaces are proximate to each other when said groove member means receives said tongue member means with a translative, sliding fit.
Claim 6
Dependent Claim
45 words
An instrument as recited in claim 3, wherein said groove member means further includes a stop member which closes the groove defined by at least one of said first and said second hook-like members at one end thereof for limiting translative movement of said housings.
Claim 7
Dependent Claim
101 words
An instrument as recited in claim 5, wherein said tongue member includes a recessed portion located at and terminating in one end of said side surface thereof, said recessed portion having a surface substantially parallel to said side surface to form a first locking member, and wherein said groove member means further includes a projection extending from said second one surface located adjacent said stop member to form a second locking member, said second locking member having a surface complementary to said surface of said first locking member so that said surfaces thereof frictionally engage upon translative movement of said housings.
Claim 8
Dependent Claim
64 words
An instrument as recited in claim 5, wherein said first tongue has defined therein a notch at one point along its length, and further comprising a rotatable latch means supported in said first hook-like member, said rotatable latch means having a dependent arm extending into said first groove formed by said first hook-like member for engaging said notch upon translative movement of said housings.
Claim 9
