Abstract

The utility model discloses an endoscopic mask. The endoscopic mask comprises an annular airbag (3), a soft rubber (2), a small hole (4), an oxygen connecting tube (8) and a mask body (9). The soft rubber (2) is connected with the mask body (9), the annular airbag (3) is connected with mask body (9), the small hole (4) is formed in the mask body (9), and the mask body (9) is provided with the oxygen connecting tube (8). The endoscopic mask is simple in structure, efficient and capable of achieving endoscopy, non-invasive ventilation and sputum suction simultaneously.

Description

A kind of endoscopy face shield

Technical field

This utility model relates to a kind of endoscopy face shield, belongs to field of medical devices.

Background technology

Along with the raising of medical skill, painless endoscopy, as a kind of simple noninvasive test mode, is to understand digestive tract by scope intuitive manner, is one of method that current digestive tract examining is the most effective, diagnosis is the highest, extensive use clinically.Bronchoscopy is the lower respiratory tract that elongated bronchoscope per os or nose are inserted to patient, through glottis, enters trachea and bronchus and far-end more, the pathological changes of directly observing trachea and bronchus, and check accordingly and treat according to pathological changes.Broadly comprise through the biopsy of bronchoscope focus, bronchical mucosa, through the saturating wall lung of bronchoscope biopsy (Transbronchial LungBiopsy, TBLB) and through Aspiration-needle biopsy (Transbronchial Needle Aspiration, TBNA).Most of pulmonarys and airway disorders, as tumor, interstitial lung disease, granulomatous disease and some infectious disease need to be by determining diagnosis through bronchoscopic biopsy, within 1897, Germany scientist Killian takes out foreign body with esophagoscope in trachea, and this is with hard scope, to enter the hard bronchoscopy that tracheal bronchus carries out for the first time in history.After this, hard bronchoscope has been continued to use nearly 70 years, because hard bronchoscopy is limited in scope, and needs to operate under general anesthesia, and its clinical practice is limited.

Along with fibre-optic development, engendered flexible scope.The scope that enters each branch of trachea has been designed in the Ikeda of Japanese OLYMPUS company in 1964, make the fiberoptic bronchoscope of standard, definite designation in 1967 is flexible branchofiberoscope (flexible bronchofibroscope), it can directly enter the lesions position of required inspection, takes pathological tissues and cytolgical examination.Because flexible branchofiberoscope is soft, patient is lying on the back or seat all can check, patient is without general anesthesia, and mirror body is elongated and can arrive tracheal bronchus and far-end more thereof, thereby has clear superiority in the diagnosis of air flue pathological changes and treatment.

The 1980s, along with the development of electronic technology, a kind of new Flexible bronchoscopy arises at the historic moment, i.e. electric bronchoscope.It is charge-coupled device (CCD) to be arranged on to scope front end replace original inner lens, replaces fibre bundle to pass picture, rather than conduct by prism or optical fibers by cable.In February, 1987, the listing of the first in the world platform electronics Flexible bronchoscopy.Electric bronchoscope operation Shi doctor no longer carries out facing to eyepiece, but facing to display screen, its image is more clear, picture is more true to nature, more convenient to operate.

At present, prior art is generally applied intravenous anesthesia mode sedation and analgesia clinically, to reach painless object.Yet while carrying out painless fiberoptic bronchial endoscopy, the anaesthetic using likely can cause respiration inhibition and respiratory tract obstruction, and severe patient also can cause cardiac arrest, if control not in time ventilation, implement assisted respiartion, can lead to disastrous consequence.

Utility model content

This utility model, for the shortcoming of prior art, provides a kind of for Endoscopic face shield, prevents that anaesthetic from causing respiration inhibition and respiratory tract obstruction, guarantees the safety of patient in art.

A kind of endoscopy face shield of this utility model, comprise annular air-pocket 3, soft rubber body 2, hole pipe 4, oxygen adapter 8 and mask body 9, it is characterized in that: soft rubber body 2 is connected with mask body 9, annular air-pocket 3 is connected with mask body 9, hole pipe 4 is on mask body 9, and oxygen takes over 8 on mask body 9.

Described soft rubber body 2 is provided with jack 6.

Described hole pipe 4, with external screw thread, is also provided with nut 10.

On described mask body 9, four are provided with column 1

Described soft rubber body 2 peripheries are provided with active rubber calotte 7, and active rubber calotte 7 can clog jack 6.

Described annular air-pocket 3 is communicated with Non-return air valve 5.

Compared with prior art a kind of endoscopy face shield of this utility model has the following advantages:

1. the many patients of pair oral secretion, have avoided mistake to inhale, and reduce patient suffering, guarantee patient safety;

2. simple, efficient, realize the effect that endoscopy, noinvasive ventilation, suction sputum carry out simultaneously.Improve Endoscopic efficiency, guaranteed the effective ventilation of patient in checking process, guaranteed the property checking.
