Abstract

A system involving disconnectably connectable sensor and adaptor units which can be employed to allow for the collection and communication, along with ECG data, of other physiologic parameter data whose condition is helpful in a evaluating communicative ECG data. Connection between the adaptor and sensor units of the invention effects the establishment of circuitry which allows (a) for the use of conventional ECG lead conductors alone to be responsible for carrying all categories of data, (b) for providing fail-safe communication of ECG data, and (c) for defining through different interfacial connective structures the actual characters of other-parameter data that will be communicated outwardly from a subject.

Claims

1. Two-part apparatus for operative connection to the distal end of a set of conventional ECG lead conductors for collecting from a person, and for transferring to a region outside of that person in a manner which enables such transferring to take place solely via conductors which form part of such a lead conductor set, plural-parameter physiologic (PPP) data, including ECG data, said apparatus comprising

a first part including circuit substructure which is directly and operatively connectable to one or more conductors in such a lead-conductor set,

a second part which is detachably connectable to said first part, and which includes circuit substructure that is detachably connectable to the circuit substructure in said first part, and

person-proximity, plural-parameter, data-gathering sensor (PPP) structure carried on said second part and operatively connected to the circuit substructure in said second part,

attachment of said first and second parts producing operative joinder of said two circuit substructures into a cooperative co-action circuit which enables the transfer of gathered PPP data from said sensor structure to one or more conductors in such a lead-conductor set.

2. The apparatus of claim 1, wherein said sensor structure is designed to be capable of gathering, in addition to ECG data, at least two categories of other-parameter physiologic data, said first and second parts each includes an interface connector structure which connects with the interface connector structure associated with the other part when the two parts are connected, and these interconnect structures are configured in such a manner that other-parameter information which is communicated to the region of joinder between the two parts from the second part is selectively different from the related information which is received by the first part, and specifically in such a fashion that less than all of the other parameter-data made available by the second part is communicated through and by said first part.

3. The apparatus of claim 2, wherein the difference which exists between communicated and received other-parameter data with regard to communication between said first and second parts results from the fact that the physical structures of the two interface structures differ.

4. The apparatus of claim 1 which further includes power-source structure nominally disposed within one of said two parts, which power-source structure is inactive when said first and second parts are detached, and is active when said first and said parts are attached, to supply operational electrical power which flows in both of said circuit substructures.

5. The apparatus of claim 4, wherein said circuit substructures and said power-source structure are constructed in such a manner that when the first and second parts are attached, and the circuit substructures are joined, the active/inactive state of the power-source structure is irrelevant to the delivery of ECG data through the two parts.
