Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to a PSG fixing headgear for children. Background Art

[0002] Polysomnography (PSG) is a technology that simultaneously records and analyzes multiple sleep breathing physiological indexes for sleep medicine research and the diagnosis of sleep breathing diseases, and is known as the "gold standard" for diagnosing sleep breathing disorders. Its monitoring principle is to collect relevant vital sign parameters and physiological signals during sleep through electrodes and sensors attached to the patient's body. There are a total of 27 lead electrodes, and 13 parts are collected on the head and face: 8 for electroencephalogram, 2 for eye movement, and 3 for the mandible; in addition, 2 for grounding, 4 for leg movement, 2 for electrocardiogram, 1 for body position, 1 for blood oxygen saturation, 2 for chest and abdomen belts, 1 for thermosensitivity, and 1 for pressure sensor. Usually, it needs to be monitored for more than 8 hours.

[0003] At present, disposable surgical caps are mostly used as fixing headgears in clinical practice. The following problems are found during use: (1) The size of the headgear cannot be adjusted; (2) The headgear is prone to slipping and shifting upwards, resulting in falling off; (3) The mandibular strap cannot be adjusted; (4) It is easy to pull the lead wires when turning over. Chinese Patent CN 216984912 U discloses a PSG electroencephalogram positioning protection fixator, including a headgear. At least one upper rope body is provided above the headgear. A connection component is provided between the upper rope body and the headgear. A fitting piece is movably provided on the upper rope body, and slots are spaced at the bottom of the fitting piece; the connection component includes first magic tapes at both ends of the upper rope body, and second magic tapes are circumferentially provided on the outer side of the headgear. The first magic tape and the second magic tape are adhesively arranged; a lower rope body is provided below the headgear, and the lower rope body is fixedly connected to the headgear. A soft pad is fixedly provided in the middle of the lower rope body. Through the provided fitting piece, the fitting piece can be displaced so that the fitting piece corresponds to the electrodes on the patient's head, thereby fixing the electrodes and making the electrodes not easy to slide during use and being firmly fixed. However, due to the large difference in head circumferences of children of different ages, it is difficult for the above fixator to match the head circumferences of children of different ages at the same time. Moreover, most children are lively and active, which easily causes the upper rope body of the above fixator to fall off, resulting in inaccurate monitoring results.
