Description
Technical field
The utility model relates to technical field of medical equipment, and in particular to a kind of end-expiratory carbon dioxide patient monitor is matched
Part.
Background technique
End-expiratory carbon dioxide has been considered to be except body temperature, breathing, pulse, blood as a kind of hurtless measure monitoring technology
The 6th basic vital sign other than pressure, arterial oxygen saturation.We can be by measurement end-expiratory carbon dioxide come anti-
Reflect various variations such as patient ventilation, circulation, metabolism.
During end-expiratory carbon dioxide measurement, aqueous vapor ingredient is entered in end-expiratory carbon dioxide monitor host
Face will affect the exact value and damage machine itself of carbon dioxide.Traditional filter is to filter aqueous vapor by one sheet of film,
There is countless apertures above film, there is a small water accumulating cup below film.During the filtration process, gas passes through membrane filtration
Time is only zero point several seconds, and filtering is very incomplete, still has a large amount of aqueous vapor and enters in machine, for a long time, causes to lead
Machine damage, to influence measurement accuracy.And traditional filter needs to regularly replace ponding cup.
Utility model content
The purpose of this utility model is that: to avoid aqueous vapor from entering end-expiratory carbon dioxide monitor host, and to avoid
Filter is regularly replaced, a kind of gas dry pipe for end-expiratory carbon dioxide patient monitor is provided.
The technical solution of the utility model are as follows: a kind of gas dry pipe for end-expiratory carbon dioxide patient monitor, it is wrapped
It includes: fluoro containing polymers ion exchange membrane tube, the first connector and the second connector；
First connector is mounted on one end of fluoro containing polymers ion exchange membrane tube, the second connector be mounted on fluoro containing polymers from
The other end of proton exchange pipe；
Fluoro containing polymers ion exchange membrane tube is coated with one layer of netted protective case.
Fluoro containing polymers ion exchange membrane tube has very strong hydrophily, after breathing gas enters the present apparatus, fluorine-containing height
After molecular ion exchange membrane absorbs the vapor being passed through in it, vapor is concentrated on ionic membrane, and the vapor on ionic membrane is dense
Spend, vapor place diffusion from from the place of high concentration to low concentration, finally with height higher than the water vapor concentration in outside air
Fluoro containing polymers ion exchange membrane tube is discharged in the form of concentration vapor；To guarantee to be after present apparatus discharge when breathing gas
Dry gas.Protective case is socketed in outside fluoro containing polymers amberplex and shields, and which is provided with mesh, steams convenient for water
Gas discharge.
Specifically, the eyed structure of protective case is diamond shape, material is medical PVC.
Further, be guarantee drying effect, fluoro containing polymers amberplex pipe range 15cm, pipe thickness be 0.1~
0.15mm。
Specifically, the first connector is female Luer connector, for connecting nasal oxygen tube.
Second connector is public female Luer, for connecting the adapter of end-expiratory carbon dioxide patient monitor.
The utility model has the advantages that the utility model uses fluoro containing polymers ion exchange membrane tube as drying part, fluoro containing polymers
Ion exchange membrane tube has very strong hydrophily, and the vapor in expiration can reach the outside of film through membranous wall, to guarantee
The drying property of gas is discharged, the vapor the separated gas discharge high as humidity will not generate any condensed water.Benefit
With the utility model without periodic replacement, easy to operate, drying effect is good.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Wherein: 1- fluoro containing polymers ion exchange membrane tube, the first connector of 2-, the second connector of 3-, 4- protective case.
Specific embodiment
The following examples illustrate the utility model, but is not limited to the range of utility model.
