Embodiment 1

[0033] A double-layer infusion bag vacuum detection method, comprising the following steps:

[0034] (1) Place the double-layer infusion bag that has formed a vacuum state in the testing room, the vacuum index of the packaging of the infusion bag is 0.5Mpa, and keep the air pressure in the testing room at normal pressure;

[0035] (2) If the double-layer infusion bag has a paper packaging box, remove the paper packaging box of the double-layer infusion bag, expose the outer layer 1 of the double-layer infusion bag, and glue the outer layer of the infusion bag near the infusion tube 3 Sealing tape 4, the sealing tape is made of viscous silica gel, which can be closely bonded to the outer layer of the infusion bag and has certain flexibility.

[0036] (3) After the sealant is bonded tightly, the sampling needle 5 of the vacuum detection device is sequentially pierced through the sealant and the outer layer of the infusion bag, so that the sampling needle enters the interlayer be...

Embodiment 2

[0041] A double-layer infusion bag vacuum detection method, comprising the following steps:

[0042] (1) Place the double-layer infusion bag that has formed a vacuum state in the testing room, the vacuum index of the packaging of the infusion bag is 0.5Mpa, and keep the air pressure in the testing room at normal pressure;

[0043] (2) Remove other packaging of the double-layer infusion bag, such as boxes and boxes, to expose the outer layer of the double-layer infusion bag, and stick a sealant on the outer layer of the infusion bag near the infusion tube. Choose viscous silica gel for the sealant. The viscous silica gel contains 0.5% sodium alginate and 0.5% sodium chloride. You can add the formula amount of sodium alginate and sodium chloride during the preparation of the silica gel.

[0044] (3) After the sealant is bonded tightly, the sampling needle of the vacuum detection device is sequentially pierced through the sealant and the outer layer of the infusion bag, so that t...

Embodiment 3

[0049] A double-layer infusion bag vacuum detection method, comprising the following steps:

[0050] (1) Place the double-layer infusion bag that has formed a vacuum state in the testing room. The vacuum index of the packaging of the infusion bag is 1Mpa, and the air pressure in the testing room is kept at normal pressure; the temperature in the testing room is controlled at 20 ° C, and the humidity is controlled at 60 %.

[0051] (2) Remove other packaging of the double-layer infusion bag, such as boxes and boxes, to expose the outer layer of the double-layer infusion bag, and stick a sealant on the outer layer of the infusion bag close to the infusion tube. The interlayers of the bags are connected. Choose viscous silica gel for the sealing tape, which can be tightly bonded to the outer layer of the infusion bag and has certain flexibility.

[0052] (3) After the sealant is bonded tightly, the sampling needle of the vacuum detection device is sequentially pierced through t...

Abstract

The invention discloses a vacuum degree detection structure and detection method of an external compound packaged five-layer coextrusion infusion bag. The vacuum degree detection method includes the following steps that: a double-layer infusion bag is arranged in a detection room; the outer layer of the double-layer infusion bag is exposed, a sealing adhesive patch is pasted on a position on the outer layer of the infusion bag, where the position on the outer layer of the infusion bag is adjacent to an infusion tube; after the sealing adhesive patch is tightly pasted, the sampling needle of a vacuum detection device pierces the sealing adhesive patch and the outer layer of the infusion bag sequentially, so that the sampling needle can enter the interlayer of the infusion bag; and a vacuum degree parameter can be obtained; after detection is finished, the sampling needle is pulled out, and the sealing adhesive patch is squeezed to seal a sampling needle hole. According to the vacuum degree detection structure and detection method of the invention, the sealing adhesive patch is pasted on the external package of the infusion bag, and the infusion bag is plugged into the interlayer, and therefore, whether the vacuum degree of the infusion bag satisfies requirements can be accurately detected, and the defect that the inner-layer package of the infusion bag is pierced can be avoided, and the sampling needle hole can be sealed through silica gel, and the detected package can be also repeatedly detected, so that vacuum decay data can be obtained.

Description

technical field [0001] The invention relates to the technical field of infusion packaging quality detection, in particular to a method for detecting the vacuum degree of a five-layer co-extrusion infusion bag with an outer composite bag. Background technique [0002] The infusion bag is a commonly used medical device. The infusion bag is packaged in two layers of inner and outer packaging. First, it can prevent the inner packaging from being scratched and allow bacteria to enter the inner packaging; second, it can draw a vacuum between the inner packaging and the outer packaging. [0003] Because the inner packaging may have extremely thin leak holes that bacteria can enter, because in the capillary-like micro-slits, when the surface tension formed by the viscosity of the liquid medicine and the pressure of the liquid medicine reach a relative balance, the leakage of the liquid medicine will be very slow , Subtle and not visible to the naked eye for a short time. By drawing...
