Medical oxygen mask

Abstract

The invention relates to the technical field of medical equipment, in particular to a medical oxygen mask which comprises a mask body. Two mutually symmetric elastic bands are connected onto the maskbody, an upper breather pipe is mounted at the bottom end of the mask body, a lower breather pipe is arranged on the lower portion of the upper breather pipe, a rotary control ring is connected between the lower breather pipe and the upper breather pipe, an oxygen bag is mounted at the bottom end of the lower breather pipe, an upper embedded fixed plate is mounted inside the upper breather pipe, upper air holes are formed in the upper embedded fixed plate, and an upper sliding rail groove is formed around the surface of the upper breather pipe. The rotary control ring connected between the upper breather pipe and the lower breather pipe can manually and freely control the quantity of oxygen entering the upper breather pipe and the lower breather pipe, the respiratory capacity of patients can be adjusted according to specific circumstances of the patients by the aid of the same oxygen mask, oxygen supply requirements of different patients can be met, and clinical treatment is greatly facilitated.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a medical oxygen mask. Background technique [0002] As an important device in the medical field, oxygen masks are getting more and more attention from the market and medical institutions. Oxygen masks generally connect the cup of the mask to the oxygen generator through the connecting tube, and supply oxygen to the cup through the oxygen generator. The patient can pass through the cup. To breathe the required concentration of oxygen, the specifications and sizes of the existing oxygen masks are generally fixed, and the internal oxygen flow rate per unit time is generally maintained within a certain range, which leads to the fact that the same oxygen mask cannot be adjusted according to the specific conditions of the patient. The breathing volume of the patient requires the use of products of different specifications corresponding to different patients, which brings a c...
