FIXATION CONTROL FOR A PATIENT INTERFACE

摘要

The present invention relates to a detector, a patient interface and a patient interface system comprising this detector, and a method for preventing the formation of red marks due to the wearing of a patient interface (12) that is pressing against the skin of the patient (18) for a longer time. With the detector and via the method, the blood flow and/or the occlusion of the blood vessels of the patient (18) are monitored, and the assessed degrees are used as a basis to adjust the patient interface (12) in order to reduce the force pressing against the skin of the patient (18), such that the formation of red marks is prevented.

主权项

1. Patient interface system, with
a patient interface for providing a patient with a flow of gas, with a headgear for attaching the patient interface to the patient, and at least one adjustment mechanism for regulation of a force for attaching the patient interface to the patient with the headgear, and a detector for monitoring a degree of blood flow through at least one blood vessel of the patient, with at least one sensor and at least one monitoring unit, wherein the at least one sensor is able to detect characteristic data of a blood flow through the at least one blood vessel and is connected to the at least one monitoring unit for transmitting the detected data to the at least one monitoring unit, wherein the at least one monitoring unit is able to receive the data from the at least one sensor and is able to assess the degree of blood flow through the at least one blood vessel based on these data, wherein the at least one monitoring unit is able to provide a signal based on the assessed blood flow through the at least one blood vessel, and wherein the at least one adjustment mechanism is configured to regulate the force for attaching the patient interface to the patient with the headgear based on the signal provided by the detector.
