Description

Technical Field

[0001] This utility model relates to the field of medical packaging technology, specifically to an anti-collision packaging structure for medical knee joints. Background Technology

[0002] The knee joint, composed of the medial and lateral condyles of the femur, the medial and lateral condyles of the tibia, and the patella, is the largest and most complex joint in the human body, and is also prone to injury. It is a trochlear joint. Artificial knee joints are widely used in the medical field today. However, current packaging methods for artificial knee joints suffer from poor stability, inadequate packaging effect, poor shock absorption, and insufficient protection for the artificial knee joint.

[0003] For example, the announcement number CN214296973U is titled "Medical Knee Joint Packaging Structure". The device includes an outer box, an inner blister box that is snapped into the outer box, the opening of the inner blister box facing upwards and having a detachable blister cover at the opening, and a detachable protective part inside the inner blister box. Through the arrangement of the inner blister box and the outer box, the artificial knee joint is wrapped and protected by the protective part, which improves the protection effect of the artificial knee joint and reduces its damage rate.

[0004] The aforementioned devices offer low protection during use and are frequently subjected to bumps and swaying during falls or transportation, which can easily lead to damage to the artificial joint and reduce its protective effect. Therefore, we propose a shockproof packaging structure for medical knee joints to address the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a shockproof packaging structure for medical knee joints, in order to solve the problem mentioned in the background art that the above-mentioned devices have low protection during use, and are often subject to bumps and shaking during falls or transportation, which can easily lead to damage to the artificial joint and thus reduce protection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shockproof packaging structure for medical knee joints, including a packaging box;

[0007] Also includes:

[0008] A protective cylinder is installed inside a packaging box, with an open upper end. A storage box is movably engaged inside the protective cylinder, with an open upper end and a gap between the storage box and the protective cylinder. Several airbags are arranged in a circular array around the inner wall of the protective cylinder within the gap between the protective cylinder and the storage box. A limiting plate is installed at the bottom of the storage box, movably engaging with the bottom of the protective cylinder. An air pump is installed on one side of the inner wall of the packaging box, and a ventilation groove is provided on one side of the outer wall of the packaging box, with the air pump connected to the ventilation groove. A filter screen is installed on the outer side of the ventilation groove. The air pump is connected to the protective cylinder via an air supply pipe. A cover plate is installed at the top of the packaging box, and the cover plate is hinged to the top of the packaging box.

[0009] Preferably, the protective cylinder has a connecting groove around its interior, and the air supply pipe is connected to the interior of the connecting groove. A through groove is provided between the connecting groove and the airbag, and the through groove is connected to both the connecting groove and the interior of the airbag.

[0010] Preferably, the cover plate has a movable groove on the side surface near the packaging box, and a pressing plate is movably engaged inside the movable groove. One side of the pressing plate protrudes from the outside of the movable groove, and when the cover plate is closed, the pressing plate is attached to the outside of the protective cylinder and the storage box.

[0011] Preferably, the interior of the movable groove is equipped with several evenly distributed springs, and the other end of the springs is connected to the pressing plate.

[0012] Preferably, a locking tongue is provided on the outer side of the cover plate, and a lock box is provided on the outer side of the packaging box, with the lock box and the locking tongue being connected.

[0013] Preferably, a foam filling layer is provided in the gap between the protective cylinder and the packaging box.

[0014] Preferably, a rubber pad is adhered to the side of the packaging box that contacts the cover.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) By installing a protective cylinder inside the packaging box, and a storage box inside the protective cylinder, the artificial knee joint is placed inside the storage box. An airbag is set between the protective cylinder and the storage box, and an air pump is installed on one side inside the packaging box. The air pump is connected to the airbag. When transporting, the airbag is inflated and presses against the protective cylinder and the storage box. At the same time, a limiting plate is set at the bottom of the storage box. The airbag is inflated and engages the limiting plate to limit the movement of the storage box. When it is necessary to take out the storage box, the airbag is released so that there is no limitation around the limiting plate, and the storage box can be taken out.

[0017] (2) By setting a pressing plate on the inside of the cover plate, the pressing plate moves in the movable groove inside the cover plate. A spring is installed inside the movable groove. When the cover plate is closed, the pressing plate presses against the top of the storage box to limit and lock the storage box. Attached Figure Description
