Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
The utility model provides a kind of Chemical indicative card for monitoring lumen class apparatus sterilizing effect, including gas passage
Layer 1, chemical indicator coating 4 and basal layer 5, the gas passage layers 1 have tortuous gas passage 2, and the gas leads to
The lower part of channel layer 1 is tightly connected with the basal layer 5；The chemical indicator coating 4 is set on basal layer 5, and package is in institute
It states in gas passage 2, the Chemical indicative card is equipped with air admission hole 3, and the air admission hole 3 connects the extraneous and gas passage 2.
In the utility model, basal layer 5 can be synthetic plastic, such as the basal layer 5 is that polyester, polystyrene etc. have
Conducive to the material of chemical indicator attachment.
In the utility model, the chemical indicator coating 4 includes chemical indicator by coating or printing configuration in institute
It states on basal layer 5.The method of wherein described coating is not particularly limited, and can be a variety of known coating methods, such as can be with
It is screen type brushing, roller coating；The method of the printing is not particularly limited, and can be a variety of known printing processes, such as can
To be silk-screen printing, intaglio printing, flexible version printing etc..It should be noted that the prior art can be used in the chemical indicator
It realizes, is easily selected according to the difference of sterilizing methods, this is conventional means, and this practicality for those skilled in the art
Novel not make improvements, this will not be detailed here.For example, the chemical indicator can be steamed for detecting hydrogen peroxide
The indicator magma of the cryogenic gas class sterilizing methods such as vapour sterilizing or ethylene oxide sterilizing.
The shape of the chemical indicator coating 4 is corresponding with the gas passage, to realize chemical indicator coating 4
Package is in the gas passage so that chemical indicator is not directly exposed under sterilizing gas.
In the utility model, 1 bottom surface of gas passage layers has the gas passage 2 of the continuous complications of recess, gas passage 2
The structure of simulating shape tube chamber class instrument, such as the gas passage 2 are horizontally arranged in continuous U-shaped, 2 length of gas passage and curved
Number of tracks can carry out different designs according to challenge difficulty.Specifically, the cross-sectional area of gas passage 2（Width * height）It is long with channel
Degree is needed according to specific sterilizing methods, and sterilising cycle is set.Basic principle is：1）Cross-sectional area is smaller, and channel is longer,
Number of bends is more, then sterilization process is challenged bigger；2）Color change creeps distance should be proportional to sterilising cycle time length.
For example, if cross section is excessive, gas passage 2 is too short, and when sterilizing does not complete, chemical indicator coating 4 changes colour completely, then
It may not be usable for instruction sterilization process.But in view of the visuality of observation figure layer color change, gas passage width is not less than
1mm.Consider the feasibility of manufacture craft, 2 height of gas passage should not exceed gas passage width.Vapor path length can pass through
Increase number of bends to increase length.
In the utility model, the lower part of the gas passage layers 1 and the substrate can be realized by any appropriate means
Layer 5 is tightly connected, and the means include but not limited to heat-sealing, adhesive, sound wave welding or magnetic induction sealing.Preferably, institute
It states and adhesive is coated on basal layer 5, the gas passage layers 1 are connected to by adhesive seal on basal layer 5, wherein described viscous
The adhesive of such as acrylate resin, epoxyn, polyurethane adhesive ambient temperature curable may be selected in mixture.
It is highly preferred that the lower part of the gas passage layers 1 passes through on hot melting cohesion to the basal layer 5.
In the utility model, it is expected that the outside of the chemically instruction card of chemical indicator coating 4 is visible, so as to observation
Indicator discoloration is learned, while in order to realize that chemical indicator is not directly exposed under sterilizing gas, the upper end of the gas passage
It is that closing is transparent.
In the utility model, air admission hole 3 is additionally provided on the Chemical indicative card, the air admission hole 3 connects extraneous and described
Gas passage 2.Specifically, the air admission hole 3 can be set in gas passage layers 1, can also be set on basal layer 5.Into
Sealed adhesive paper 6 is equipped on stomata 3, air admission hole 3 can be sealed with sealed adhesive paper 6, open sealed adhesive paper again when in use
6, enter gas passage oxidation chemistry indicator coating 4 to reduce air.
Refering to Fig. 1-3, the air admission hole 3 is at least 2, is respectively arranged on the both ends of gas passage 2, it is preferable that it is described into
Stomata 3 is 2.When in gas passage 24 color of chemical indicator coating from outside to inside all change colour when then may determine that sterilizing into
Work(；If chemical indicator coating 4 does not change colour completely in gas passage, illustrate that sterilizing gas does not reach complete sterilizing pipeline
It is internal, it can be determined that sterilizing failure.
Refering to Fig. 4-6, in the utility model, the air admission hole 3 can be 1, described set on one end of gas passage 2
Index line is additionally provided in gas passage layers 1.When 4 color change of chemical indicator coating then may be used more than index line in gas passage 2
To judge to sterilize successfully, otherwise sterilizing failure.
It should be noted that the Chemical indicative card of 1 air admission hole than two or more air admission holes Chemical indicative card to going out
The challenge of bacterium technique is big, there is the apparatus sterilizing of cecum tube chamber available for simulation.
For the utility model in sterilization process, sterilizing gas diffuses into gas passage 2 and gas passage by air admission hole 3
Chemical indicator coating 4 in 2, which carries out reaction, makes its discoloration.It is elongated since gas passage 2 is narrow, simulate tube chamber class instrument
Structure, gas diffusion to tube chamber depths needs the time.So the chemical indicator at gas access can first change colour.When going out
When the bacterium time is long enough that gas fully diffuses to tube chamber depths, can just it change colour far from the chemical indicator at gas access.By
This, by observing the color change interval of chemical indicator, we may determine that whether sterilizing gas can diffuse to tube chamber instrument depth
Place.
The Chemical indicative card of the utility model utilizes the sterilization process of cryogenic gas particularly suitable for monitoring, as such as peroxidating
Hydrogen low-temperature plasma sterilization, low temperature formaldehyde steam sterilizing process, ethylene oxide sterilizing process or ozone sterilization process.
Embodiment described above only expresses the embodiment of the utility model, and description is more specific and detailed, but simultaneously
Cannot the limitation to the utility model patent range therefore be interpreted as, as long as the form institute using equivalent substitution or equivalent transformation
The technical solution of acquisition should all fall and be within the protection scope of the utility model.
