Description

Respiratory treatment mask

The present invention relates to a mask, in particular to a respiratory treatment mask, which can be connected to a breathing tube of a breathing apparatus, and can make the breathing tube rotate universally, so that the patient can rotate regardless of the position of the breathing apparatus relative to the breathing apparatus. In the proper direction, avoid excessive bending of the breathing tube and cause the gas supply to be unsmooth, and even cause the mask to leak due to pulling.

A respiratory treatment mask is a type of wear on the patient's head for the patient to connect to a breathing apparatus for breathing through the breathing apparatus. US Patent Publication No. 2009/0044808 discloses a respiratory treatment mask having a cover body and a headband disposed at a nose of a patient, and a mask on the body of the mask for respectively abutting and Slightly extend into the nostrils to ensure that oxygen can be delivered to the patient's nasal cavity. The outer cover body can be connected to the breathing tube of a breathing apparatus so that the breathing apparatus can deliver oxygen to the patient's nasal cavity. The headband is placed on the mask body and can be attached to the patient's head to ensure that the mask body can be securely attached to the patient's nose.

However, the above-mentioned mask body and the breathing tube are fixed only in a generally fixed manner, and the breathing tube cannot be rotated relative to the mask body. When the relative position of the breathing device changes to the patient, the breathing tube must be bent in different directions. If the bending degree is too large, the internal passage of the breathing tube will be narrowed to affect the flow rate of oxygen delivery, and even the breathing tube is too curved and easy to The breathing apparatus is separated from each other or accidentally detached from the mask body, causing treatment interruption and endangering the life of the patient.

The present inventors have invented a respiratory treatment mask in view of the problem that the conventional breathing treatment mask and the breathing tube cannot be rotated relative to each other, thereby causing the breathing tube to be easily bent to affect the oxygen delivery, and improving the deficiency and deficiency thereof.

The main object of the present invention is to provide a respiratory treatment mask which can be connected to a breathing tube of a breathing apparatus and can rotate the breathing tube in a universal direction so that the patient can rotate to an appropriate direction regardless of the position of the breathing apparatus. To avoid excessive bending of the breathing tube, resulting in poor oxygen supply or even accidental separation of the breathing tube from the respiratory treatment mask.
