Description

Medical breathing mask

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a medical breathing mask.

Background

With the development of modern medical technology, endoscopes as extensions of eyes and hands of doctors have reached the state of 'no holes and no entering'. By endoscopy, the following diseases can be diagnosed: inflammation, ulceration, benign and malignant tumors occurring in the digestive tract (including esophagus, stomach, duodenum, small intestine and large intestine); benign and malignant lesions of liver, gallbladder and pancreas ductal system; and benign and malignant lesions of abdominal organs. For example, upper gastrointestinal endoscopy, also known as esophagogastroduodenoscopy or EGD, is the insertion of a small tube with lights and a camera at its tip into the upper gastrointestinal tract for viewing, the first part of the oesophagus, stomach and small intestine, the duodenum. In an examination, the patient is in a lateral sitting position, and the physician inserts the endoscope into the mouth and into the stomach via the esophagus (food conduit from the mouth to the stomach).

Insert and whole inspection process at all endoscopes, need the scope mouth pad to strut patient's mouth and make the body of incisor unable interlock scope, and the patient very easily secretes secretion or other body fluids in inspection process, especially when the patient takes place to chock and coughs, can't prevent the splash of secretion, can cause the pollution of medical personnel and environment.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a medical breathing mask which can realize insertion examination in cooperation with an endoscope and effectively prevent droplets.

The purpose of the utility model is realized by the following technical scheme:

the utility model provides a medical respirator, medical respirator is including being used for covering the regional respirator body of the facial region of wearer and anti-overflow leak pad subassembly, the respirator body wholly is to the evagination bowl form, and the inboard is formed with the recess, anti-overflow leak pad subassembly includes mouthful pad and anti-overflow device, mouthful pad is worn to establish on the respirator body just to the region of the wearer's mouth, it holds the oral pad passageway that the scope passes through to open in mouthful pad, mouthful pad passageway intercommunication is external and the recess, anti-overflow leaks the device setting and is in the tip of mouthful pad and is arranged in the recess. The wearer in the present invention means a patient.

The whole breathing mask body is arc-shaped and outwards convex bowl-shaped.

The mouth pad is of a hard tubular structure. The mouth pad can effectively help a wearer open the mouth so that an endoscope of an upper digestive tract can pass through the mouth pad channel in the mouth pad and then extend into the digestive tract for examination or treatment, and meanwhile, the mouth pad can prevent the wearer from biting the endoscope.

The anti-overflow device is of a rubber elastic one-way valve structure.

The anti-overflow device comprises a connecting seat, a connecting seat channel allowing an endoscope to pass through is arranged in the connecting seat, the front end of the connecting seat is connected with the mouth pad, a plurality of valve clacks with elasticity are arranged at the rear end of the connecting seat, the valve clacks are folded, and the connecting seat channel is sealed to be located at an opening far away from one side of the mouth pad. This connecting seat is as the basic part of whole anti-overflow hourglass device, be used for connecting the mouth pad, thereby accomplish the fixed arrangement of whole anti-overflow hourglass device, the connecting seat passageway realizes the entering and the withdraw from of scope, because the valve clack of closure state sets up the outside at the connecting seat, and extend to one side of keeping away from the mouth pad by the rear end of connecting seat, so can't directly realize switching on from the outside (the outside of valve clack is followed to this side indication), only prop open the valve clack of closure state from the inboard and just can realize switching on (this inboard indicates the inboard from the valve clack), guarantee the one-way conduction structure. This anti-overflow device can avoid the liquid or the gaseous direct discharge that the person of wearing produced, can prevent to pull out the mucus of adhesion on the scope body when withdrawing from the scope simultaneously.

The side edges of the adjacent valve clacks are mutually connected, so that the whole valve clack is in a state of opening at two ends, and the endoscope is better wrapped.
