Embodiment
In order to illustrate more clearly of the embodiment of the present application or technical scheme of the prior art, below in conjunction with the accompanying drawings and specifically
Embodiment further illustrates to the utility model.
Embodiment 1
A kind of vim and vigour reagent bag of multi-layer film structure as Figure 1-Figure 2, including reagent bag 1, set on the reagent bag 1
There is an outlet 2, the reagent bag 1 includes reagent bag film 3, and the reagent bag film 3 is the multi-layer film structure mutually to fit, the multilayer
Membrane structure includes polyethylene film 41, coextrusion-lamination film 42, pure aluminium film 43 and nylon membrane 44, and bonding agent is provided between each adjacent film
Layer 45, the polyethylene film 41 is at least two layers, and the coextrusion-lamination film 42, pure aluminium film 43 and nylon membrane 44 are in two strata second
Between alkene film 41.
In embodiment 1, coextrusion-lamination film and nylon membrane reduce the oxygen transmission rate of reagent bag and resistance moisture rate, pure aluminium film carry
Hardness support is supplied, reagent bag film uses polyethylene film two layers up and down, has both reduced the oxygen transmission rate and resistance moisture of reagent bag
Rate, the outer surface of reagent bag film is also set to be advantageous to heat sealing processing.So made of composite membrane both ensured can reagent bag intensity,
By oxygen transmission rate and moisture vapor permeable rate are preferably minimized, so as to ensure that reagent saves and not degenerate for a long time, vim and vigour calibration stable reagent is reliable.
Using the technical scheme of embodiment 1, due to using multi-layer film structure, making its oxygen transmission rate and resistance moisture rate that geometry be presented
Series reduces, and substantially prolongs reagent storage and useful life, avoids reagent from being scrapped during use because rotten in longer, drops
Low manufacturing cost and use cost, check valve make reagent to be flowed to out of bag outside bag, avoid the pollution of reagent.
Embodiment 2
On the basis of embodiment 1, the outlet 2 is provided with check valve 20.The switching device of reagent bag and blood gas analyzer,
Using one-way valve structures, the blood gas analyzer of clinical diagnosis continuously or discontinuously can extract reagent out of reagent bag automatically.
Further, the thickness of the multi-layer film structure is 0.10-0.12mm.Using the multi-layer film structure of above-mentioned thickness,
Its oxygen transmission rate and resistance moisture rate substantially reduce, and its manufactured vim and vigour reagent bag thickness is moderate, it is not easy to deformation and leakage.
Further, the reagent bag 1 includes two layers of reagent bag film 3, and the edge 30 of two layers of reagent bag film 3 carries out heat
Sealing.The jacket of reagent bag is carried out using heat-sealing vocal imitation skill, technique is simple, it is not easy to leakage, low manufacture cost.
Further, the coextrusion-lamination film 42 is multi-layer co-extruded high-barrier composite membrane.Multi-layer co-extruded high-barrier composite membrane,
The fields such as packaging for foodstuff, industrial goods packaging are widely used in, multi-layer co-extruded high-barrier composite membrane has preferably resistance dampness gas, well
Pliability, the function such as heat sealability and the transparency.
The multi-layer co-extruded high-barrier composite membrane that the present embodiment is applied, specifically a kind of EVOH multi-layer co-extruded high-barriers are compound
Film, it is the copolymer of vinyl alcohol and ethene, its co-extrusion film composition：PE/PA/EVOH/PA/PE, PE/PA/EVOH/PA/PE/PE/
The forms such as PE, if the coextrusion-lamination film only with individual layer, on the one hand, composite membrane is very thin（0.075mm）, intensity do not reach reagent
Packaging standard requirement, be on the other hand not met by vim and vigour reagent to high-gas resistance, high resistant is wet and gas barrier light requirement, so stilling need
Compound other film layers again.
Further, the lamination order of the multi-layer film structure is polyethylene film, pure aluminium film, nylon membrane, multi-layer co-extruded height
Obstruct composite membrane and polyethylene film.
Polyethylene stable chemical performance, polyethylene film, which is placed on innermost layer and outermost reason, is:One is easy for reagent bag
Heat-sealing fitting, second, to avoid packing material and reagent reacting, causes reagent to go bad.In multi-layer co-extruded high-barrier composite membrane is placed on time
Layer, air-liquid can be obstructed to greatest extent and penetrates into PA layers and corrosion pure aluminium film, it is ensured that reagent bag meets standard requirement.Using upper
The lamination order stated, by verification experimental verification, transport standard requirement, 2-3 times of its life longer are stored by reagent.
Embodiment 2 is when in use, first multiple once again with bonding agent by multi-layer co-extruded high-barrier composite membrane, pure aluminium film and nylon membrane
Synthesize the reagent bag film that thickness is 0.10-0.11mm；Hot edge seal for reagent bag is firm, each multiple again in the outside of above-mentioned composite membrane
Layer of polyethylene film is closed.So made of composite membrane both ensured can reagent bag intensity, by by oxygen transmission rate and moisture vapor permeable rate drop
To minimum, so as to ensure that reagent saves and not degenerate for a long time, vim and vigour calibration stable reagent is reliable.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
