Abstract

A pulse oximetry sensor having an elongate flexible body, an emitter and a detector mounted adjacent the lower surface of the body in a spaced apart relation. First and second attachment members are mounted on the upper surface of the body and are aligned respectively with the emitter and detector. A disposable flexible member has an adhesive on one side and first and second couplers spaced apart a distance equal to that between the first and second attachment members. Each coupler is constructed and arranged to couple to one of the attachment members for coupling the body to the flexible disposable member in cooperation with the adhesive. The member is constructed and arranged to mount the body on a patient with the emitter and detector opposite one another.

Claims

1. A physiologic condition sensor comprising

an elongate flexible body having upper and lower surfaces, an emitter and a detector mounted on the body in a spaced apart relation adjacent to the lower surface thereof,

first and second attachment members mounted on the upper surface of the body and being aligned respectively with the emitter and the detector,

a disposable flexible member having an adhesive on one side thereof, and first and second couplers spaced apart a distance equal to that between the first and second attachment members and each being constructed and arranged to couple to one of the attachment members for coupling the body to the flexible member in cooperation with said adhesive, the flexible member being constructed and arranged to mount the body on a patient'"'"'s tissue with the emitter and detector on the opposite sides thereof,

each attachment member and coupler defining a coupled pair aligned respectively with the emitter and detector, each coupled pair extending above the surface of the flexible member and being visible when the flexible member and the body are mounted on the patient'"'"'s tissue to permit alignment of the emitter and the detector on the opposite sides thereof.

2. The sensor set forth in claim 1 and including a support extending from one end of the body, at least one conductor connected to each of the emitter and detector and extending through the flexible body and onto the support in a spaced apart relation, and a connector having means for receiving the support and contacts for electrically engaging the conductors.

3. The sensor set forth in claim 2 wherein the flexible member also engages the connector when coupled to the body to secure the connector to the body.

4. The sensor set forth in claim 1 wherein the first and second couplers each include a hole in the flexible member sized to receive, respectively, said first and second attachment members therethrough.

5. The sensor set forth in claim 4 wherein said attachment members each includes a stem portion extending from said body and an enlarged head portion, said holes being smaller than the head portions and sized to be received over said stem portions.

6. A physiologic condition sensor comprising:

an elongate flexible body having upper and lower surfaces, an emitter and a detector encapsulated in the body in a spaced apart relation and adjacent to the lower surface thereof, a substrate extending from one end of the flexible body, at least one conductor connected to each of the emitter and the detector and extending through the flexible body and onto the substrate in a spaced apart relation, a connector including a housing having an opening for receiving the substrate, contacts disposed in the housing for electrically engaging the conductors, at least one resilient latch member disposed in the housing, a catch member mounted on the body and engageable with the latch member when the substrate is received in the opening for being engaged by the latch member to latch the body to the connector, and an operator engageable with the latch member and operative when manually engaged to flex the latch member out of engagement with the catch member so that the body can be separated from the connector.

7. The sensor set forth in claim 6 and including first and second attachment members mounted on the upper surface of the body and being aligned, respectively, with the emitter and the detector, a disposable flexible member having an adhesive on one side thereof, and first and second couplers spaced apart a distance equal to that between the first and second attachment members and each being constructed and arranged to couple to one of the attachment members for coupling the body to the flexible member in cooperation with said adhesive, the flexible member being constructed and arranged to mount the body on a patient'"'"'s tissue with the emitter and the detector on the opposite sides thereof, each attachment member and coupler defining a coupled pair aligned respectively with the emitter and the detector, each coupled pair extending above the surface of the flexible member and being visible when the flexible member and the body are mounted on the patient'"'"'s tissue to permit alignment of the emitter and the detector on the opposite sides thereof.

8. The sensor set forth in claim 7 wherein the flexible member also engages the connector when coupled to the body to secure the connector to the body.

9. A physiologic condition sensor comprising:

a flexible body having upper and lower surfaces, and an emitter and a detector mounted on the body in a spaced apart relation adjacent to the lower surface thereof;

first and second attachment members mounted on the upper surface of the body and being aligned respectively with the emitter and the detector;

a flexible member having an adhesive on one side thereof and first and second couplers spaced apart a distance equal to that between the first and second attachment members, each coupler being constructed and arranged to couple to one of the attachment members so as to couple the body to the flexible member, the flexible member being constructed and arranged to mount the body on a patient'"'"'s tissue with the emitter and detector on the opposite sides thereof;

each attachment member and coupler defining a coupled pair aligned respectively with the emitter and detector, each coupled pair extending above the surface of the flexible member and being visible when the flexible member and the body are mounted on the patient'"'"'s tissue to permit alignment of the emitter and the detector on the opposite sides thereof.
