Abstract
The utility model discloses a medical heat and humidity exchange device, including casing and a pair of sponge filter, the casing includes pipy casing body, and a pair of sponge filter sets up the both ends at the casing body respectively, wherein, each sponge filter's whole surface is equipped with hydrophilic coating. Hydrophilic coating has better lock waterborne ability, also can remain the temperature in the gas better simultaneously to medical heat and humidity exchange device's the nice and warm humidification effect that adds has been improved.
Description
Technical field
This utility model is related to medical heat and humidity exchange.
Background technology
Medical heat and humidity exchange（HME）It is a kind of clinical conventional medical apparatus and instruments, is mainly used in anesthesia disease
In the medical care path of people, ICU intensive care units patient etc..At present, it is little less than 72 when the time of patient's expection intubation breathing
When, under artificial ventilation state intubation breathing patient typically by hot and humid area dress is added on artificial airway device
The mode put is heated to gas and is humidified.The operation of hot and humid area device is by retaining temperature in the gas that breathes out from patient
Degree and humidity, and patient is given by most of temperature and humidity for retaining in upper once expiratory phase.
Common medical heat and humidity exchange include housing and a pair of sponge filter cores.Housing includes the housing of tubulose
Body and the mouthpiece for enclosure body is connected with the tracheal intubation of human body, mouthpiece are arranged on the centre of enclosure body
Position, a pair of sponge filter cores are separately positioned on the two ends of enclosure body.The gas of patient's exhalation enters through tracheal intubation, mouthpiece
Enter in the inner chamber of enclosure body, the heat carried in gas and moisture are absorbed by a pair of sponge filter cores respectively.Once inhale upper
During gas, the humidity and temperature preserved in a pair of sponge filter cores is entered in suction gas, changes the suction of humidity and temperature
Enter gas to enter back in human respiratory tract.
Existing medical heat and humidity exchange in terms of heating and the effect for humidifying need further to improve.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of doctor with good heating and humidifying effect
With heat and humidity exchange.
To solve above-mentioned technical problem, technical solution adopted in the utility model is：
Medical heat and humidity exchange, including housing and a pair of sponge filter cores；Housing includes the enclosure body of tubulose,
A pair of sponge filter cores are separately positioned on the two ends of enclosure body；Wherein, the whole outer surface of each sponge filter core is provided with hydrophilic coating.
After above-mentioned technical proposal, this utility model at least has following technique effect：
1st, set on the surface of a pair of sponge filter cores according to the medical heat and humidity exchange of this utility model embodiment
There is hydrophilic coating, hydrophilic coating has more preferable water lock performance, while also can preferably retain the temperature in gas, so as to improve
Heating and the humidifying effect of medical heat and humidity exchange；
2nd, according to the enclosure body of the medical heat and humidity exchange of this utility model embodiment in positive docking port pipe
Inner wall surface be provided with distributary division such that it is able to the gas for breathing out the patient flowed into from mouthpiece is to enclosure body two ends point
Stream, makes temperature that a pair of sponge filter cores positioned at enclosure body two ends are retained and moisture relatively uniform, and then makes to enter into people
The temperature and humidity of the suction gas in body respiratory tract is also more uniform, both improves heating and humidifying effect, also improves trouble
The comfort of person.
Description of the drawings
Fig. 1 is the overall appearance schematic diagram of the medical heat and humidity exchange according to one embodiment of this utility model.
Fig. 2 and Fig. 3 are respectively illustrated according to the medical heat and humidity exchange of one embodiment of this utility model not
With the cross-sectional view of angle.
Specific embodiment
This utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Refer to Fig. 1 to Fig. 3.Housing is included according to the medical heat and humidity exchange of one embodiment of this utility model
1 and a pair of sponge filter cores 2.
Housing 1 includes the enclosure body 11 of tubulose, and a pair of sponge filter cores 2 are separately positioned on the two ends of enclosure body 11, respectively
The whole outer surface of sponge filter core 2 is provided with hydrophilic coating.As hydrophilic coating has more preferable water lock performance, while also can be more preferable
Ground retains the temperature in gas, so as to improve heating and the humidification effect of this utility model medical heat and humidity exchange
Really.
In the present embodiment, the central through hole 110 of the enclosure body 11 of tubulose is shaped as ellipse, each sponge filter core 2
Cross sectional shape be circular or oval；110 interference fit of central through hole of each sponge filter core 2 and enclosure body 11.Preferably
It is that the stop part 3 being respectively arranged at two ends with for backstop sponge filter core 2 of enclosure body 11, stop part 3 are connected with enclosure body 11
Connect.
Further, include using according to the housing 1 of the medical heat and humidity exchange of one embodiment of this utility model
In the mouthpiece 12 that enclosure body 11 is connected with the tracheal intubation of human body, mouthpiece 12 is arranged on the interposition of enclosure body 11
Put；Enclosure body 11 is provided with for the gas that will be flowed into from mouthpiece 12 to enclosure body in the inner wall surface of positive docking port pipe 12
The distributary division 13 of 11 two ends shunting.The shape of cross section of distributary division 13 includes but is not limited to isosceles triangle, circular arc etc..
The gas of patient's exhalation divides in the central through hole 110 that tracheal intubation, mouthpiece 12 enter into enclosure body 11
The gas of the exhalation can be shunted by stream portion 13 to 11 two ends of enclosure body, make a pair of the sponge filter cores 2 positioned at enclosure body two ends
The temperature and moisture for being retained is relatively uniform.In upper once breathing process, the humidity preserved in a pair of sponge filter cores 2 and temperature
Enter in suction gas, make the temperature and humidity for sucking gas entered in human respiratory tract also more uniform, both improved
Heating and humidifying effect, also improve the comfort of patient.
