Description

Sealing cover of infusion bag

Technical Field

The utility model relates to a medical appliance, in particular to a medical infusion bag.

Background

The infusion bag has the characteristics of good chemical stability, excellent air tightness and high temperature resistance, and the packaging quality and the quality guarantee storage period of the medicine are better improved. Infusion bag usually includes the bag body (usually adopt the PP film preparation) and interface (usually adopt the PP material preparation), still need set up the sealed lid of the gasket of sealed usefulness and fixed gasket on the interface, and sealed lid center is equipped with the opening so that the syringe needle of transfusion system pierces, but causes the gasket to warp the evagination when pulling out the syringe needle easily to the seepage appears, consequently needs to improve.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the not enough among the above-mentioned background art, provide a sealed lid of infusion bag, should seal the lid and should be able to firmly fix the gasket to have simple structure, simple to operate's characteristics.

The technical scheme of the utility model is that:

the infusion bag sealing cover comprises a cover ring and a cover plate arranged at the top of the cover ring, an inner hole is formed in the middle of the cover plate, and a clamping edge which protrudes downwards and surrounds in the circumferential direction is arranged on the inner side of the cover plate; the method is characterized in that: the cover plate also extends a plurality of distances toward the center of the inner hole to form an annular reinforcing ring.

The thickness of the reinforcing ring is smaller than that of the cover plate.

The width of the reinforcing ring is 1.0-1.5 mm.

The utility model has the advantages that:

the utility model can provide enough clamping force, ensure that the gasket is firmly fixed between the interface and the sealing cover, and can not move when the needle head is pulled out, thereby effectively ensuring the product quality; in addition, the device also has the characteristics of simple structure and convenience in installation.

Detailed Description

The present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following embodiments.

As shown in fig. 1, the sealing cover for the infusion bag comprises a cover ring 1 and a cover plate 2 arranged at the top of the cover ring, wherein an inner hole 3 is formed in the middle of the cover plate, and a clamping edge 4 which protrudes downwards and surrounds in the circumferential direction is arranged on the inner side of the cover plate. The cover plate also extends towards the center of the inner hole for a plurality of distances to form an annular reinforcing ring 5, the thickness of the reinforcing ring is smaller than that of the cover plate, the width of the reinforcing ring is 1.0-1.5mm (preferably 1.25mm), and the radius of the inner hole is 3.5-4.0mm (preferably 3.75 mm).

As shown in fig. 5, the end surface of the gasket 6 is provided with a groove 7 and three recesses 8. As shown in fig. 3, the gasket is fixed in the sealing cover of the infusion bag, the clamping edge of the sealing cover of the infusion bag is embedded into the groove of the gasket, and the reinforcing ring of the sealing cover of the infusion bag covers the groove part of the gasket, so that the support of the gasket is enhanced, the gasket is ensured to be firmly positioned on the inner side of the sealing cover, and the gasket is prevented from deforming and turning outwards.
