Abstract

The system comprises an intracavity device with an insertable portion having on its outer surface a sensor module which comprises at least a sensor of temperature, humidity or both; a second group of sensors comprising at least a volume sensor, a pressure sensor or both, wherein the fluid flows through the volume and/or pressure sensors; a fluid insufflation module; and a monitoring and control of the homeostasis module connected to the sensor module and to the second group of sensors and which comprises a processing unit. The method comprises insufflating fluid into the cavity, to maintain a working volume and maintain the homeostasis of the cavity in a continuous manner, in particular the distensibility, temperature and humidity.

Claims19

Dependent claims

A modular system for the monitoring of the homeostasis in cavities for endoscopic procedures, comprising:

at least one intracavity device, having an insertable portion to be arranged in the interior of a cavity and a channel for the passage of fluid towards the cavity;
at least one sensor module, the at least one sensor module comprising at least one temperature or humidity sensor, or both, configured to measure the temperature and/or humidity inside the cavity;
a variable output humidifier and heating module;
a fluid insufflation module configured to infuse a fluid into the interior of the cavity;
a second group of sensors, comprising at least a volume sensor, and at least a pressure sensor, the second group of sensors being arranged so that the fluid being insufflated flows through the volume sensor and the pressure sensor;
a monitoring and control of the homeostasis module connected to the at least one sensor module, to the second group of sensors, and to the fluid insufflation module, and which comprises a processing unit;
and
at least a first conduit which has a first end, connected to the monitoring and control of the homeostasis module, and a second end connected to the intracavity device;
the processing unit being configured to control the modular system to implement the following actions:
a) insufflate fluid into the cavity during a predetermined period;
b) measure a volume of insufflated fluid;
c) close a passage of fluid to the cavity when a predetermined volume is reached;
d) record a pressure increase in the cavity which has been generated by this volume increase;
e) repeat a) to d);
f) based on the obtained volume and pressure measures, determining a distensibility curve of the cavity and a point of inflection of the distensibility curve beyond which the same increase in volume results in a greater increase of the pressure in the cavity;
and,
g) determine a range of optimal volumes as a range of volumes below the point of inflection or about the point of inflection;
and the processing unit being configured to control the modular system to additionally implement the following actions:
operate the humidifier and heating module to modify the temperature and/or the humidity of the fluid being insufflated based on the data obtained by the sensor module;
record in the processing unit a working volume to be maintained in the cavity;
operate the fluid insufflation module to insufflate fluid into the cavity;
obtain a measure of the volume of the cavity based on the data obtained by the second group of sensors;
compare the measured volume of the cavity with the recorded working volume;
responsive to a difference, in absolute value, between the measured volume and the recorded working volume being above a predetermined threshold, insufflate fluid to the cavity or extract fluid from the cavity to reestablish the recorded working volume in the cavity.
