Description
Technical field
The present invention relates to a kind of breathing intubation artificial nose, for the air filtration of artificial respiration's air flue, belongs to medical apparatus and instruments
Manufacture technology field.
Background technology
Tracheal intubation is used for the clinical existing long period, when various respiratory failures and anesthesia surgery is treated, is both needed to
To use breathing intubation, but due to air malignant bacteria in institute, viral more and human airway will to the multiple of suitable gas
Ask, so in breathing intubation arrange artificial nose, also known as hot and humid area filter more, it is that one kind is connected to breathing intubation outer end,
For the device that human body supplies warm and moist gas, cardinal principle is to stop and adsorb antibacterial and virus by filter element, and will
The temperature of characteristics of contaminated respiratory droplets gas and moisture carry out damp and hot exchange with suction gas, to supply the gas of more suitable human body.Existing
The artificial nose of Clinical practice, the pore grenadine how to be made using several layers of absorbent material and hydrophilic compounds or Double layer corrugated paper sample
Filter element carries out air filtration, can collect the heat in characteristics of contaminated respiratory droplets gas and aqueous vapor and retain a part, inhales in human body
During gas to warm, the state of humidifying bring in air flue, but this kind of artificial nose filter effect is poor, if under certain area increase
The filter element number of plies such as refinement hole pattern yarn or corrugated paper, can strengthen filter effect to a certain extent, but hinder human body respiration
Power is increased, and easily causes dyspnea to patient and the problem for hypoxgia.
For solving the deficiency of above-mentioned artificial nose, China Patent No. 201020282722.8 discloses a kind of artificial nose, including
Housing, heating plate, absorbing membrane, filter membrane, the artificial nose have filtration to antibacterial and pathogenic bacteria, and to entering the external world of housing
Gas has the function of warming and humidifying.But the patent is not disclosed under limited filter area both to have been realized preferably filtering effect
Really, reduce the technical scheme of respiratory resistance again, do not solve the technical contradiction of above-mentioned filter area and respiratory resistance.
In order to solve the number of drawbacks of Traditional Man nose, medical apparatus and instruments research staff needs badly and develops a kind of breathing vapour lock
The excellent breathing intubation artificial nose of little, filter effect.
Content of the invention
It is an object of the invention to provide a kind of breathe intubation artificial nose, the artificial nose not only effectively increases filter area
Reduce breathing vapour lock, realize the filter effect for stopping antibacterial and virus, also there is gas to external world to carry out the function of heating and moistening,
The final gas for the suitable suction of human body supply.
The present invention provides a kind of breathing intubation artificial nose, and including filter assemblies, the filter assemblies include the first filtration
Part, first filter element are tightly connected in join domain by filtration membrane and are formed, after being tightly connected formed by filter membrane
The internal cavities that piece is wrapped up out are filter element inner chamber, filter at least provided with one first on the filtration membrane of the first filter element
Component openings, the first filter element open at one end and filter element intracavity inter-connection, the other end can with person's windpipe stoma or
Breathing intubation is connected.After ambient atmos are through filtration membrane filtration, filter element inner chamber entered, is then opened by the first filter element
