Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a high-concentration oxygen mask.
Background
High concentration oxygen masks, also known as non-rebreathing masks, are commonly used when high concentrations of oxygen are needed, e.g., critical patients, unstable patients; the patient breathes through the face guard, and the inspiratory valve is opened, makes oxygen follow the suction in the oxygen storage bag, and the patient exhales through the expiratory valve, when the oxygenerator breaks down or the oxygen generation raw materials are lacked, can lead to the patient to suffocate even die.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: the technical problem that a patient is easily suffocated when oxygen supply is insufficient in a traditional high-concentration oxygen mask is solved.
The invention provides a high-concentration oxygen mask which comprises a body, wherein an oxygen storage bag is arranged on the body, and a safety valve is also arranged on the body; the safety valve comprises a valve core and a through hole arranged on the body, wherein an installation rod is arranged in the through hole and divides the through hole into a first through hole and a second through hole, the central position of the valve core is fixedly connected with the installation rod, one part of the valve core extends out of the through hole and is adhered to the outer wall of the body to cover the first through hole, and the rest part of the valve core extends into the through hole and is adhered to the inner wall of the body to cover the second through hole.
The oxygen storage bag is connected with the medical oxygen supply machine through a hose, and the medical oxygen supply machine fills oxygen into the oxygen storage bag; in a conventional state, the second through hole is connected with the valve core; when a patient inhales, the air pressure in the body is reduced, the first through hole is connected with the valve core, when the patient exhales, the air pressure in the body is increased, and the valve core part covering the first through hole is bent outwards, so that the exhaled air is led out from the first through hole; when the oxygenerator breaks down or the oxygen preparation raw materials disappearance leads to the oxygen suppliment not enough, the negative pressure that the patient produced through breathing in makes the case part that covers the second through-hole crooked to body inside to make indoor air admission oxygen mask, solved the patient and led to the problem of suffocating because of the oxygen suppliment is not enough.
Furthermore, the first through hole is provided with a stop lever connected with the mounting rod, and the arc-shaped wall of the second through hole is provided with a stop block. The arrangement of the stop lever prevents the valve core part covering the first through hole from extending into the body; the setting of dog not only can avoid covering the case part of second through-hole and stretch out the body outside, and the dog is equipped with the interval with the installation pole moreover, is convenient for the case installation.
The patient through oxygen treatment needs to record respiratory frequency, but often estimates inaccurately and leads to the record bad, so this problem is solved in further improvement, specifically, still install transparent pipe on the body, transparent pipe bottom with body coupling and intercommunication, transparent pipe top is sealed, the inside instruction ball that is equipped with of transparent pipe. The indication ball is used as a visual index of the respiratory frequency, the oxygen flow entering the oxygen mask pushes the indication ball to the top of the transparent tube, and the negative pressure generated when a patient inhales pulls the indication ball to the bottom of the transparent tube, so that the patient can see the indication ball immediately after breathing every time, and the accuracy of recording the respiratory frequency of the patient is improved.
Further, a pipe cap is connected to the top of the transparent pipe in a threaded manner. Due to the arrangement of the pipe cap, the processing difficulty of the transparent pipe is reduced, and the transparent pipe is convenient to clean and the indicating ball is convenient to replace.

Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
As shown in fig. 1, the invention is a high concentration oxygen mask, comprising a body 1, an oxygen storage bag 2 is arranged at the lower end of the body 1, and two symmetrically arranged safety valves 3 are arranged on the body 1; as shown in fig. 2, the safety valve 3 includes a valve core 31 and a through hole 11 disposed on the body 1, as shown in fig. 5, a mounting rod 12 is disposed in the through hole 11, the mounting rod 12 divides the through hole 11 into a first through hole 111 and a second through hole 112, as shown in fig. 2, the central position of the valve core 31 is fixedly connected with the mounting rod 12, a part of the valve core 31 extends out of the through hole 11 to be attached to the outer wall of the body 1 and cover the first through hole 111, and the rest of the valve core 31 extends into the through hole 11 to be attached to the inner wall of the body 1 and cover the second through hole 112;
