Abstract
A disposable pressure sensor system includes a disposable sensor assembly having at least one sensing element, carried on a housing or frame, and at least one electrical connector and/or mechanical connector for connecting the sensing element(s) to an external apparatus or device. The mechanical and/or electrical connectors are integrated in the housing or frame so that both the connector(s) and sensing element(s) are packaged in a single part. The assembly can be integrated in or attachable to a fluid carrying module, such as a dialysis cartridge, such that the sensing element(s) can sense the fluid in the module.
Claims20
A disposable pressure sensor for use in conjunction with an apparatus that includes a fluid chamber, the disposable pressure sensor comprising:
- a single piece molded plastic housing having one or more traces thereon;
- a pressure sensor secured relative to the single piece molded plastic housing, wherein the pressure sensor includes one or more electrical signals that are electrically connected to corresponding traces of the single piece molded plastic housing;
- at least one wire bond for electrically connecting the one or more electrical signals of the pressure sensor to the corresponding traces of the single piece molded plastic housing;
- a port integrally formed with the single piece molded plastic housing for transmitting a fluid pressure to the pressure sensor;
- a mechanical connector integrally formed with the single piece molded plastic housing, the mechanical connector configured to cooperate with a corresponding mechanical connector of the apparatus to snap or latch the single piece molded plastic housing to the apparatus such that the pressure sensor would be in fluid communication with the fluid chamber of the apparatus via the port;
- and
- an electrical connector integrally formed with the single piece molded plastic housing, the electrical connector configured to cooperate with a corresponding electrical connector of the apparatus to mechanically guide and electrically connect the one or more traces of the single piece molded plastic housing to one or more conductors of the corresponding electrical connector of the apparatus.
A disposable pressure sensor for use in conjunction with an apparatus that includes a fluid chamber, the disposable pressure sensor comprising:
- a housing having one or more conductors;
- a pressure sensor secured relative to the housing, wherein the pressure sensor includes one or more electrical signals that are electrically connected to corresponding conductors of the housing;
- a mechanical connector integrally formed with the housing, the mechanical connector configured to cooperate with a corresponding mechanical connector of the apparatus to mechanically connect the housing to the apparatus such that the pressure sensor is in fluid communication with the fluid chamber of the apparatus;
- and
- an electrical connector integrally formed with the housing, the electrical connector configured to cooperate with a corresponding electrical connector of the apparatus to mechanically guide and electrically connect the one or more conductors of the housing to one or more conductors of the corresponding electrical connector of the apparatus.
