Packaging lining plate

Abstract

The invention relates to a packaging lining plate. The packaging lining plate comprises a bearing plate and a limiting piece, a storage groove is formed in the bearing plate, at least part of a to-be-packaged object is placed in the storage groove, the limiting part comprises an attaching part and a holding part, at least part of the attaching part is attached to the bearing plate, the holding part can be dissociated out of the bearing plate, the bearing plate is provided with a groove structure matched with the attaching part, the assembling and disassembling functions of the bearing plate and the attaching part are achieved through horizontal sliding, a sliding direction of the limiting part is not parallel to an initial taking-out direction of the to-be-packaged object relative to the bearing plate, and an included angle between the sliding direction and the initial taking-out direction is defined as theta, wherein theta meets the following mathematical formula that theta is greater than 0 degree and less than or equal to 90 degrees, and the to-be-packaged object can be limited in a space defined by the storage groove and the limiting part. The packaging lining plate is wide in application range, free of damage during dismounting, high in safety and capable of achieving effective fixing, and meanwhile personalized customization for different shape requirements can be achieved conveniently.

Description

technical field [0001] The invention belongs to the field of packaging, and in particular relates to a packaging liner used for separating and fixing an occluding plate and an anchor frame of an occluder. Background technique [0002] At present, there are many products on the market in the field of medical devices that are dumbbell-shaped as a whole, and have two upper and lower parts in structure, and the upper and lower parts are connected by a "waist" formed by relatively small connectors, such as The vast majority of left atrial appendage occluders, atrial septal stents, ventricular septal defect occluders, and atrial septal defect occluders are almost all in the shape of an "I" shape with upper and lower parts. [0003] Taking the commonly used "disc cover" left atrial appendage occluder as an example, it includes two parts, the anchor frame and the occlusion disk. The anchor frame is usually equipped with a tip barb for anchoring the left atrial appendage. When squee...

Problems solved by technology

[0003] Take the commonly used "disc cover" left atrial appendage occluder as an example, which includes two parts, the anchor frame and the occlusion disk. The anchor frame is usually equipped with a tip barb for anchoring the left atrial appendage. When squeezed, the barbs on the anchoring frame can easily puncture the flow-blocking membrane on the blocking disc, resulting in product defects. At the same time, the product may not return to its original shape or even break after being squeezed for a long time. lead to potential safety hazards in the product

These problems are fatal to the occluder. Once the defective occluder is implanted in the patient's body, it will cause irreparable damage to the patient's life and health.

The existing packaging design on the market is relatively complicated, and the protection range is limited, and it is difficult for users to operate, and it is difficult to solve the problems faced by the product in the existing packaging method. For example, the patent CN209650816U relates to a packaging partition, which has The following questions:

[0004] Before assembly: a) The shape of the two slot tabs of the upper partition is T-shaped, the shape of the receiving openings of the two slots of the lower partition is double L-shaped, and the width of the two slot tabs of the upper partition is larger than that of the lower partition The width of the receiving openings of the two double L-shaped card slots on the panel requires that the card slot tabs of the upper partition be forcibly bent before they can be put into the receiving openings of the lower partition board. The bent tabs of the card slots will Form sharp corners and damage the objects to be packaged; b) The two slot tabs of the upper partition and the two double L shapes of the lower partition are rotating structures (need to rotate 90°), so that the objects to be packaged and the rotating structure need to be kept Only a certain distance can ensure that the goods to be packaged are not affected, thereby increasing the design space of the lower partition and increasing the cost; c) The bending structure of the lower partition is only formed by bending a flat sheet, and the strength is insufficient, and it will grow after bending. There will be a certain recovery effect under static time, which will cause the deformation of the protective cavity formed by the bending structure, and cannot effectively protect the object to be packaged
