In at least one example embodiment, the second part is releasably connected to the first part.
Claims22
An apparatus comprising:
- at least one pressure sensor unit including
- a housing having at least one pressure chamber and at least one catheter connector where a passageway is present from the catheter connector to the pressure chamber,
- at least one of said at least one pressure chamber includes a pressure sensor, and
- at least one electrical connector;
- a module including
- at least one module connector for releasably connecting to said at least one electrical connector of said at least one sensor unit, and
- a wireless transmitter in electrical communication with said at least one module connector;

- and
- a processor connected to said memory and said wireless transmitter.
7 more elements
A system for measuring and transmitting data to an external device, the system comprising:
- at least one catheter transferring fluid having a pressure;
- at least one pressure sensor connected to said at least one catheter, said at least one pressure sensor detecting the pressure of the fluid;
- at least one cassette housing said at least one pressure sensor and having a one way valve in fluid connection with one of said at least one catheter;
- and
- a transmitter releasably connected to said at least one cassette, said transmitter receiving an electrical signal representing a fluid pressure from said at least one pressure sensor and transmitting a signal based on the electrical signal to the external device.
2 more elements
An apparatus comprising:
- at least one cassette including
- a housing having a pressure chamber,
- a one-way valve connected to the pressure chamber,
- a catheter connecter connected to the pressure chamber at an end opposite to said one-way valve,
- a sensor in said housing and exposed to said pressure chamber such that said sensor can detect a pressure of fluid present in said pressure chamber, and
- an electrical connector connected to said sensor;
- a communications module including
- at least one connector releasably connected to one of said at least one electrical connector,
- a wireless transmitter connected to said at least one connector, and
- a radio frequency receiver;
- and
- wherein when said at least one electrical connector is connected to said at least one connector, an electrical pathway exists between said sensor and said transmitter.
9 more elements
