Definitions
- This invention relates to low profile connectors especially useful in the biomedical field. More specifically, this invention relates to preferably rotatable, restriction fit electrode connectors or adapters that are particularly useful to connect transcutaneous electronic nerve stimulator (TENS) electrodes to suitable electrical signal generating means. (Electromyographic, and sensing, monitoring or stimulating electrodes could also be connected or coupled in a practice of this invention.) Even more particularly, this invention relates to restriction fit electrode connector assemblies or adapters in which a connector body slides over an upstanding member, e.g., a bulbous post, of an electrode, "snapping" into place so as to permit secure, rotatable electrical coupling between the connector and the electrode.
- TENS transcutaneous electronic nerve stimulator
- connectors used in the medical industry to connect various skin interface means, e.g., TENS electrodes, monitoring and diagnostic ECG electrodes, to separate electrical means.
- Such separate electrical means could include electrical pulse generators, or signal processors.
- these connectors permit the user to employ relatively inexpensive disposable electrodes with relatively more expensive connector means which can then be reused. None of these connectors have the advantages of the present invention, viz., a low profile, a secure coupling or connection, preferably rotatable restriction fit and ease of detachment from the electrode once the electrical measurement has been completed.
- the present invention is a connector for slidable and preferably rotatable conductive engagement with an upstanding connecting member of an electrode, the connector comprising: an at least partially conductive connector body having a multiplicity of sides, a top and a bottom, the connector body having therein a channel.
- the channel communicates with one side and the bottom of the body so as to slidably and restrictively receive the member while preferably permitting rotation between the body and the electrode.
- the channel has a widened portion opening to the one side and tapering to a narrower portion, the narrower portion of the channel having substantially non-parallel sides (including partially hemispherical) and a terminus at approximately the center of the connector body.
- the channel may also be characterized as interiorly concave so as to cooperate with and electrically and physically couple with the member; and electrical connector means for connecting said connector body to separate electrical input or output means.
- the connector body of the present invention has a grip means on the top thereof so a ⁇ to provide ease of connector-electrode coupling and decoupling.
- the connector body is substantially square, having four sides.
- this invention comprises a connector assembly comprising the above-described connector and a cooperative skin interface means having, as a minimuin, an upstanding member, stud or post.
- the cooperating, upstanding member provides electrical coupling to the electrode structure, itself.
- the skin interface means is a TENS electrode.

- FIG 1 shows a top view of a connector body 10 of the invention which, in this depiction, comprises a top 12 and four sides 14a-14d.
- a top view of a connector body 10 of the invention which, in this depiction, comprises a top 12 and four sides 14a-14d.
- FURNISHED UPON FILING As shown, primarily for NOT FURNISHED UPON FILING
- Connector body underside or bottom 28 has channel or groove 18 therein. Although channel 18 does not extend all the way through connector body 10 (nor through top 12) , it is conceivable that it could do so. Channel 18 is in communication with one side (14d) of connector body 10 and leads approximately to the center of the bottom 28 thereof. Channel 18 has a wider portion 18a adjacent the region where it intersects side 14d and narrows 18b to a semi-circular terminus or stop 30. Stop 30 would abut an upwardly projecting portion of a biomedical electrode, e.g., a bulbous post, and provide a secure restriction fit therefor.
- a biomedical electrode e.g., a bulbous post
- the composition of the connector body 10 is chosen so as to provide sufficient resilience or compressibility in the sides 18a-18b of channel 18 and stop 30 to cause, e.g., an electrode post, to "snap" into place adjacent stop 30, thereby providing a secure restriction fit.
- Electrode 31 comprises upstanding connecting member which, in this embodiment, is a circular, bulbous post 32. Electrode 31 further includes a backing member 34 which could be constructed of a flexible, breathable, material such as spunlace. Overlying the base portion of post 32 would be a conductive adhesive gel 36.
- the adhesive gel is a poly AMPS gel commercially available from the Promeon Division of Medtronic, Inc. under the designation RG-62D. Other commercially available polymeric or natural conductive gels would be suitable for this application.
- a release liner 38 is a release liner 38. Release liner 38 could, for example, be release coated "Mylar" polyester film.
- Post 32 is likely to have a larger, circular base section 33 (shown in shadow on Fig. 2) which provides current distribution capability to the electrode.
- Post 32 is silver plated plastic, thereby providing electrical connection to conductive gel 36.
- Post 32 may be made of any conductive plastic or other conductive material.
- the particular details of the construction of an electrode for use in the present invention are not critical with the exception that any such electrode must have an upstanding male connector member.
- United States Patent No. 4,273,135, the details of which are incorporated by reference herein, is one of many possible electrode constructions that could be used in the practice of this invention.
- the release liner 38 would be removed from the electrode and the electrode placed on a patient's skin. The electrode then would be electrically coupled or connected to an electronic nerve stimulator by means of connector 10.
- Fig. 4 shows a view of the present invention looking approximately straight into channel 18. Electrode 31 is shown after it has been "snapped" into connector 10. As is shown in Fig. 4, the sides or walls 19 of channel 18 are substantially non-parallel. Channel 18 is interiorly concave (as viewed essentially normal from bottom 28) , being, in the embodiment, approximately truncated triangular in cross section. The interior shape of channel 18 i ⁇ selected so as to prevent detachment or lifting off of connector body 10 from the cooperating upstanding member of the electrode which is employed. Various other concave configurations could be used for channel 18 provided connector body 10 is adequately secured to the upstanding member.
- a keyhole shaped interior i.e., cross-like in section
- the configuration for channel 18 adjacent stop 30 permits it to receive and restrictively hold the upstanding member of an electrode.
- Electrode 31, by virtue of the present invention and the fact that upstanding member 32 is circular, can be freely rotated with respect to connector 10. This is particularly advantageous in application because it permits the patient to be mobile without interrupting the intended therapy.
- Fig. 5 shows a fragmentary section taken along line 5-5 in Figs. 1 and 4.
- Fig. 5 shows wire 22 insulatively enshrouded by insulator 24.
- metal sheath 40 which, in construction of the invention, is wrapped around wire 22 to enhance electrically coupling to connector body 10.
- Metal sheath 40 is a preferred means to integrally connect wire 22 to connector body 10 because it provides a more secure anchor therewith.
- FIG. 7 i ⁇ a fragmentary section taken along line 7-7 of
- FIG. 8 is a top plan view of this embodiment of the invention.
- a connector 50 having an electrical lead 51 which provides an electrical connection with an electrical input or output (not shown) .
- the electrical lead 51 comprises a strain relief portion 52 and a wire portion 53.
- the electrical lead 51 may be positioned elsewhere on the connector 50; for example, in the position of the electrical lead 51a.
- a raised central portion 54 to which indicia (not shown) may be optionally applied, such as, for example, the trademark of the manufacturer.
- Fig. 9 is an elevational view of the embodiment of Fig. 8. Depicted in Fig. 9 is the connector 50,the electrical lead 51, and the raised central portion 54. Also depicted is a channel 55 having a wider portion 56 and a narrower portion 57.
- Fig. 10 is a bottom plan view of the embodiment of Fig. 8.
- Fig. 10 depicts the connector 50 and the electrical lead 51 with strain relief portion 52 and wire portion 53.
- the wire 58 extends from the connector block 59 to the narrower portion 57 of the channel 55 and along the narrower portion 57 and the stop portion 57a such that electrical contact may be achieved between the wire 58 and the upstanding connecting member 32 shown in Fig.
- first recesses 60 and second recesses 61 are present due to the use of pins in the mold (not shown) to retain the wire 58 in a correct portion during the molding process for the connector 50 and do not serve any function in the finished connector 50.
- Fig. 11 is a sectional side view taken along line 11-11 of Fig. 10. Depicted in Fig. 11 is the connector 50 and the electrical lead 51 with its strain relief portion 52 and wire portion 53. Also depicted is the central raised portion 54, the metal wire 58, a second recess 61, and the channel 55 with its stop portion 57a. It should be noted that a pin in the mold (not shown) which formed the second recess 61 during the molding process that formed the connector 50 has provided support for the wire 58 such that the wire 58 is located at the surface of the stop portion 57a of the channel 55 and such that the wire 58 may be in electrical contact with the upstanding connecting member 32 when it is fully received in the channel 55 against the stop portion 57a.
- Fig. 12 is a sectional rear elevational view taken along line 12-12 of Fig. 10.
- Fig. 12 depicts the connector 50, the raised central portion 54, the channel 55 at the narrower portion 57, the wire 58 and first recesses 60.
- pins in the mold which formed the first recesses 60 during the molding process that formed the connector 50 provided lateral support for the wire 58 during the molding process such that the wire 58 is located at the surface of the narrower portion 57 of the channel 55 and that such electrical contact may be achieved between the wire 58 and the upstanding connecting member 32 when in Fig. 3 when the upstanding connecting member 32 i ⁇ received in the narrower portion 57 of the channel 55.
- FIG. 13 is a sectional rear elevational view taken along line 13-13 of Fig. 10.
- Fig. 13 depicts the connector 50, the raised central portion 54, the channel 55 at the narrower portion 57, the wire 58 and second recesses 61. Again, the pins in the mold (not shown) which formed the second recesses 61 provided support for the wire 58 during the molding of the connector 50.
- the connector or adaptor of this invention may comprise conductive thermoplastic.
- a preferred material for use in molding the part is carbon loaded polypropylene. This material, which is easy to work with and which is readily commercially available, is particularly electrically suited to the TENS application.
- Many other conductive thermoplastic or thermosetting polymeric (or other) materials may be employed to produce the present connector within the teaching of this invention.
- Unmoldable conductive materials e.g., metal, may also be employed. It is noted from the several views, that electrical connector 20 projects into connector body 10, and is offset and on the same side (14d) as channel 18. As discussed above, connector 20 is molded into connector body 10. This is done by conventional insert molding techniques. If a non-moldable conductive material is used, a suitable orifice connector would have to be prepared. While the separation between channel 18 and the connector 20 is not particularly critical, it should be on the order of about 0.15 cm.
- channel 18 and electrical connector 20 are on the same side of connector body 10 or are at least adjacent each other depending upon the shape of connector 10. It is conceivable that channel 18 and electrical connector 20 could be spatially separates.
- the connector or adaptor of the present invention i ⁇ low profile. A ⁇ the name suggests, this simply means that this connector permits efficient electrical connection with an electrode without upwardly projecting a substantial distance from the back of such electrode. This is particularly advantageous because in this manner interference with clothing and other patient activities is minimized.
