Description
Technical field
This utility model relates to a kind of encapsulation of medical diagnosis sensor.Be a kind of sealing system of disposable medical diagnostic sensor specifically.
Background technology
When using various remote sensing technologies that the patient is carried out blood testing, must correctly calibrate just can make to sensor as everyone knows and measure the accuracy with expection.The development of clinical diagnosis has at present promoted the development of detection system, and sensor is packaged in and is used for carrying out disposable detection in the complete testing equipment.These equipment usually and reader connect together, can carry out interactive operation with equipment.Interactive operation comprises from each sensor extracts signal, and the motion of the liquid in the Selective Control equipment, for example according to sensor sample and calibration solution is positioned.The important feature of this sensor-based system is that equipment is regularly made and regularly delivered to the client.But device fabrication and the interval that uses can be the several months.Therefore, can indicate its shelf life under certain condition on the label after the device fabrication, under situation about existing at other conditions of storage, following six months of refrigeration condition, following fortnight of room temperature.
So under specified criteria, the shelf life of sensor may be restricted, but the stability of sensor and calibration solution stability is also unaffected, former because: for calibration solution, the concentration (as potassium concentration, partial pressure of carbon dioxide etc.) of calibration analyte thing is extremely important when keeping storing.One of this way to solve the problem is that calibration solution is stored in a sealed glass container or the ampoule.The sealed container wall is not easy to make gas or liquid to exchange.But for the convenience of using, as in the head of a bed or careful test environment, equipment is designed to the outward appearance with the glass container sealing, is unfavorable for practice.The not convenient fragility that comprises packing of this utilization, and glass assembly is packaged into testing cassete, as the caused a series of problems of disposable test box.Therefore, packing of plastic layer aluminium foil bag often arranged at present.For the structure of this kind sack, the paper tinsel shell depends on its barrier property as the selection of 40 μ m aluminum cylinders, namely transports the resistance of gas, steam and liquid.Aluminium foil becomes first-selected material because its pinhole diameter is very little.There are various optical detection means to distinguish needle pore defect at present.Plastic layer is salable and avoid the direct contacting metal thin film of liquid, therefore can not cause mixing of one or more calibration solution compositions.
Though the aluminium foil shell can be used as effective barrier usually, all gases such as oxygen, carbon dioxide and water vapour still dissolve in in various degree the plastics, penetrate in the plastics matrix with certain speed.Solvent and the density that feeds intake that the chemical constituent of this speed and temperature, pressure, plastics, plastics are thrown in have functional relation.If as the calibration sample, as calibrating the pCO2 sensor with known partial pressure of carbon dioxide pCO2, hyposmosis and deliquescent pCO2 sealing effectiveness are more with a certain specific gas.The volume of liquid storage bag packing is subjected to the restriction of closure size.Further problem is how by reducing the problem that driving force reduces gas exchange as far as possible, as analyte pressure and the concentration difference on sealing two sides.Reduce temperature and can reduce gas exchange, but owing to harmful effects such as the water that freezes in the capsule may cause that sealing is broken, must this way of careful use.Therefore, refrigeration is a kind of available compromise.
Summary of the invention
The purpose of this utility model provides the generation that the problems referred to above can be avoided or be reduced to greatest extent in an a kind of aspect.Reduce infiltration and dissolubility by the hyposmosis of employing improvement and the bag sealing technology of dissolubility gas such as carbon dioxide encapsulant on the other hand.
This utility model solves its above-mentioned technical problem and adopts following technical scheme: a kind of liquid storage bag with decrement gas exchange, it mainly is configured with: crimping marginal zone, upper strata paillon foil, lower floor's paillon foil, normal fluid, sealant bead, described upper strata paillon foil and lower floor's paillon foil are divided into aluminium foil layer and plastic layer, store normal fluid between upper strata paillon foil and the lower floor's paillon foil, weld by the crimping marginal zone between upper strata paillon foil and the lower floor's paillon foil, its crimping back gauge of crimping marginal zone is smaller or equal to 4mm.
Weld by the crimping marginal zone between above-mentioned upper strata paillon foil and the lower floor's paillon foil, its welding compound is sealant bead.
Above-mentioned upper strata paillon foil, lower floor paillon foil welding back constitute liquid storage bag, and it is disposable use test box, and contains a sensor at least.
Above-mentioned upper strata paillon foil, lower floor's paillon foil are by carrying out the ultrasonic bonding of heat and pressure crimping.
Above-mentioned upper strata paillon foil, lower floor's paillon foil pass through laser weld.
The beneficial effect that the utlity model has is: the convenient transportation of liquid storage bag, also be convenient to hospital and other users storage.According to typical scenario of the present utility model, in sack manufacturing process, used advanced bag sealing technology.The thin plate that direction is opposite such as aluminium foil are bonding mutually, form a big liquids and gases antiseepage interface at seam.Available sealing flow process comprises high-new sack Sealing Technologies such as heating power crimping, pressure crimping, heating power and pressure crimping, ultrasonic bonding, metal and metal solder and laser weld.
The further technology of this utility model shows that consequent sack integrity directly depends on the integrity of fluid such as calibration solution.That is to say that in sack making, sealing, use and testing process, the character of liquid must remain unchanged.This time difference can be several months.Therefore, the sealing of sack is most important to its integrity.
