Method and system for controlling pressurization of a patient cavity using a pressure sensor of a medical appliance

A method comprising:

• positioning a medical appliance having a primary pressure sensor at or within a patient incision site;
• supplying an insufflation fluid to a patient cavity;
• a receiving one or more signals indicative of pressure measurements in the patient cavity by the primary pressure sensor;
• controlling the supply of insufflation fluid by an insufflator to the patient cavity based at least on the one or more signals indicative of pressure measurements;
• determining, by a processor associated with the insufflator, that the one or more signals indicative of pressure measurements may be inaccurate by determining at least one of:
• whether at least one of the one or more of the received signals indicative of pressure measurements is not within a predefined range of accuracy;
• whether any error data is received, the error data indicating at least one of:
• an error occurred due to an interference from a power signal;
• a wrong number of bits is received;
• data is received in a wrong format;
• or
• data is received with an improper spacing;
• whether any proper acknowledgment bits are not received;
• whether a received signal is not within an expected voltage range;
• and
• whether any updated status bits are not received;
• and
• in response to determining that the one or more signals indicative of pressure measurements may be inaccurate, controlling, by the insufflator, the supply of the insufflation fluid to the patient cavity based at least on a pressure measured by a backup pressure sensor.

An insufflator comprising:

• a pressurized fluid source;
• a processor;
• and
• a computer-readable media having logic stored thereon, the logic operable, when executed on the processor, to:
• receive one or more signals indicative of pressure measurements from a primary pressure sensor positioned on, in, or through a medical appliance, wherein:
• the medical appliance is positioned at or within a patient cavity;
• and
• the one or more received signals are indicative of a pressure of the patient cavity;
• control a supply of insufflation fluid from the pressurized fluid source to the patient cavity based at least on the one or more signals indicative of pressure measurements from the primary pressure sensor;
• and
• determining that the one or more signals indicative of pressure measurements from the primary pressure sensor may be inaccurate by determining at least one of:
• whether at least one of the one or more received signals indicative of pressure measurements is not within a predefined range of accuracy;
• whether any error data is received, the error data indicating at least one of:
• an error occurred due to an interference from a power signal;
• a wrong number of bits is received;
• data is received in a wrong format;
• or
• data is received with an improper spacing;
• whether any proper acknowledgment bits are not received;
• whether a received signal is not within an expected voltage range;
• and
• whether any updated status bits are not received;
• and
• in response to determining that the one or more signals indicative of pressure measurements from the primary pressure sensor may be inaccurate, control the supply of the insufflation fluid by the pressurized fluid source to the patient cavity based at least on a pressure measured by a backup pressure sensor.
