Abstract

The utility model relates to a medical apparatus, which is a face mask be made of transparent silicon rubber through compression casting. An integral respiratory mask is composed of an interface, a bowl cavity, a cylinder cavity and a hem cavity. The shape and wall thickness of the interface, the bowl cavity, the cylinder cavity and the hem cavity are smoothly transited. The wall thickness of the bowl cavity is twice of the wall thickness of the hem cavity. While in use, the respiratory mask is pressed directly to cover the nose and the mouth cavity of a patient, and no additional fixing device is needed. The respiratory mask is soft, so the respiratory mask can not hurt the patient. The variance in facial expression of the patient can be observed through the respiratory mask, so a doctor can treat and remedy the patient conveniently and timely.

Description

Respiratory mask

This utility model relates to a kind of medical apparatus face shield, breathing mask, uses when particularly the urgent patient being rescued oxygen therapy.

The different triangle of oxygen hood face shape profile that still continue to use and human body that existing most of medical institutions use, sealing is poor, the limit subdivision is easily overturn, oxygen easily leaks, for making its sealing, face shield must be held in patient's face, and patient is very uncomfortable, time has often been grown the facial embedding of patient has been hindered, and especially infant, neonate more is not suitable for.The aspect face shield is opaque in addition, can not in time observe the variation of patient mask expression, thereby incurs loss through delay processing and treatment to the state of an illness.

Patent announcement CN2045649 " oxygen uptake transparent face mask ", CN2056858 " the disposable anesthesia oxygen hood of air-cushion type ", CN2046388 " Dispoable medical cushion seals mask " have just solved above-mentioned existing variety of issue.But structure is complicated, also has the inflatable air bag of need, with the fixed member of patient head, uses also inconvenient.

The purpose of this utility model is to provide a kind of breathing mask, for transparent type, can in time observe the variation of patient's facial expression.Simple in structure, easy to use, patient's face can be directly be fixed on and patient can be do not injured again.

This utility model is achieved in that being right after a bowl chamber, cylindrical cavity and chamber, limit below the interface constitutes holistic breathing mask.

Fig. 1. structural representation of the present utility model.

Fig. 2. be the vertical view of Fig. 1.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

This breathing mask is made by transparent silicone rubber die casting, and is nontoxic, can carry out high temperature, autoclave sterilization, repeatedly uses.Be the middle cylinder interface (1) that through hole is arranged topmost, interface (1) size of adopting international standards, being right after the cylindrical wall below the interface (1) is the bowl chamber (2) of bowl-type cavity for conical, inner round wall, be right after columniform cylindrical cavity (3) below, cylindrical cavity (3) is right after half the lifesaving cast limit chamber (4) of shape as riving, bowl chamber (2) part wall thickness is about 2 times of chamber, limit (4) part wall thickness, and chamber, limit (4) wall thickness is 1mm.Interface (1), bowl chamber (2), cylindrical cavity (3), chamber, limit (4) four partial shapes and thickness is rounding off all, constitutes holistic breathing mask.

Interface during use (1) connects respirator resuscitator, and chamber, limit (4) directly are close to oral cavity and the nasal cavity position that covers patient.This breathing mask is mainly used in the suffocating or manually cure by oxygen therapy respiratory resuscitation during respiratory disorder and rescue and use of premature infant, neonate, infant, and also suitable adult cures by oxygen therapy and rescues and adopt during operation.

The utility model is compared with prior art: this breathing mask adopts silicon rubber to be cast into an integral manufacturing and forms, structure, technology are simple, do not need fixture, directly being close to patient's face just can use, can the embedding sick and wounded because of its softness, do not have discomfort yet, easy to use, safe and reliable, the variation of facial expression is convenient to the doctor and is in time processed and treatment in the time of observing again patient because it is transparent and cure by oxygen therapy.
