The utility model discloses an automatic ventilation device for a sewage well, and provides a solution aiming at the problems of low manual ventilation efficiency and high energy consumption of the conventional sewage well. The device is mainly composed of a jacking pipe, an air bag and a gas exchange structure, the jacking pipe is vertically and slidably arranged below the well lid, the bottom of the jacking pipe is connected with the air bag, and the gas exchange structure rotating during jacking is arranged on the well lid. The structure comprises a containing groove and a ventilation plate rotating horizontally, and the top pipe is connected with the ventilation plate through a transmission structure composed of a gear and a rack. The jacking pipe is divided into a metal section and a plastic section, a guide block is arranged on the well wall to assist the jacking pipe in sliding, and a limiting piece is arranged to control the moving range. The air bag drives the jacking pipe to reciprocate through the change of water flow in the sewage pipeline, the ventilation plate is driven to rotate through the transmission structure, and continuous ventilation in the sewage well is achieved. The device does not need external power, can efficiently complete ventilation by means of natural change of water flow, effectively reduces energy consumption, solves the problem of ventilation of scattered sewage wells, and guarantees operation safety and surrounding environment health.

The invention relates to a ventilation system and a ventilation method for the artificial ventilation of a patient. Furthermore, the invention relates to a control arrangement and a control method for controlling a ventilation arrangement belonging to the ventilation system. An anesthetic dosing component (38) provides an anesthetic gas mixture (Ng) with a calculated target concentration (con req ) ready. A ventilator (12) delivers a breathable gas mixture with the anesthetic gas mixture (Ng) to a patient-side coupling unit. The target concentration (con req ) is calculated such that it is at most equal to an upper concentration barrier (con max ) is. The upper concentration barrier (con max The risk of condensation increases with the temperature in the anesthetic dosing unit (38), the ventilator (12), and / or the surrounding environment. The invention reduces the risk of anesthetic condensation.

A ventilation system and a ventilation process artificially ventilate a patient. A control arrangement and a control process control a ventilation arrangement belonging to the ventilation system. An anesthetic dispenser unit (38) provides an anesthetic gas mixture (Ng) with a predetermined target concentration (conreq) of an anesthetic (Nm). A ventilator (12) conveys a breathable gas mixture with the anesthetic gas mixture (Ng) to a patient-side coupling unit. The target concentration (conreq) is specified so that it is at most equal to a calculated upper concentration threshold (conmax). The higher the temperature in the anesthetic dispenser unit (38), in the ventilator (12) and / or in an environment, the greater is the upper concentration threshold (conmax). The risk of anesthetic (Nm) condensing is reduced.

The invention relates to a breathing machine capable of controlling temperature and humidity of a pipeline and a display unit of the breathing machine. The breathing machine pipeline of the breathing machine is provided with a humidity monitoring control system. The system comprises a breathing pipeline, a temperature and humidity detection unit and a display unit. The temperature and humidity detection unit is arranged beside the breathing tube close to one side of the patient and is used for detecting absolute humidity and temperature and displaying the absolute humidity and temperature on the display unit in a flickering manner; the display unit is integrated with a control module, and the control module sends first control information to the heating element and / or the breathing machine flow valve to regulate and control the temperature of the breathing gas, sends second control information to the breathing machine flow valve to regulate and control the humidity of the breathing gas, and starts the heating element for heating based on the second control information. And the gas flow increased by the flow valve of the breathing machine is not reduced. The problems that in the prior art, temperature and humidity regulation and control are not synchronous, and humidity is abnormal due to cooling are solved, dynamic coordinated regulation and control of the temperature and humidity of breathing gas are achieved, and the safety of manual ventilation is improved.

Title of the Invention: Non-Invasive Ventilation Monitoring System. The invention relates to a monitoring system for a person receiving non-invasive artificial ventilation (NIV) using a medical ventilator supplying a breathing mask with a respiratory gas. The medical ventilator provides ventilation variables. A computer server receives and processes these ventilation variables to determine several statistical indicators for each variable and derive a ventilation quality score using a mathematical model that compares these statistical indicators with stored thresholds obtained through machine learning. Finally, at least one significant ventilation variable is identified among these variables, impacting the ventilation quality score more than the other ventilation variables.
