Technical Field
The utility model relates to a medical care technical field, in particular to face guard for noninvasive ventilator.
Background
The noninvasive ventilator is also called Continuous Positive Airway Pressure (CPAP), and the acronym is used for Continuous Positive Airway Pressure (CPAP). CPAP is clinically used for treating Sleep Apnea Syndrome (SAS) and related diseases, which cause blood oxygen saturation reduction, sympathetic tone increase, parasympathetic tone reduction, blood carbon dioxide concentration increase, PH value decrease and intrathoracic negative pressure increase, and seriously affect various important organ functions. In particular, brain function and cardiovascular function are affected by the disease.
The CPAP mainly comprises a single-loop respirator and a double-loop respirator, and in the using process of the respirator, because the pressure in the mask needs to be detected and oxygen is supplied according to the detected pressure, the breathing mask is not provided with air leakage holes (the double-loop respirator) or the diameter of the breathing air leakage holes is smaller (the single-loop respirator), so that the detection data is accurate and the oxygen can be supplied with high quality; when the patient uses the dual-loop respirator, it is more common that a gastric tube (i.e., a nasogastric tube) needs to be prepared, wherein the gastric tube needs to pass through the breathing mask and the face of the patient, so that a larger gap is formed between the breathing mask and the face of the patient, the accuracy of the detection data of the pressure in the breathing mask is lower, and the oxygen supply effect is also poorer.

Detailed Description
The mask for noninvasive ventilator provided by the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more fully apparent from the following description and appended claims. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention. The same or similar reference numbers in the drawings identify the same or similar elements.
A mask for noninvasive ventilator, as shown in fig. 1 to 4, comprising a mask body 1 and a ventilation tube 2 communicated with the mask body 1, wherein the structures of the mask body 1, the ventilation tube 2, devices for pressure detection and oxygen supply, etc. are consistent with those of conventional devices in the market, and are not repeated herein; the cover body 1 on with the cover body 1 communicates with each other and is provided with connecting cylinder 3, connecting cylinder 3 is the cavity shape that both ends are the open-ended, the inner wall of connecting cylinder 3 is provided with annular soft connection piece 4, the outer peripheral edges of soft connection piece 4 with the interior wall connection of connecting cylinder 3, the internal periphery is provided with the elastic connection ring 5 of loop configuration.
