Description

Technical Field

[0001] The utility model relates to a double-layer collagen membrane freeze-drying mold, belonging to the field of freeze-drying molds. Background Art

[0002] Collagen is the main component of the extracellular matrix, a natural biopolymer material, and the most abundant and widely distributed protein in mammals. Collagen has a special triple helical fiber structure, low immunogenicity, good biocompatibility, strong cell affinity, biodegradable absorption, and can promote the proliferation and growth of epithelial cells and fibroblasts, aggregate platelets to produce coagulation, accelerate granulation tissue formation and wound healing, etc. Therefore, collagen dressings are widely used in wound management.

[0003] In oral applications, the collagen membrane used needs to have a double-layer structure, with one layer being dense and smooth and the other layer being loose and rough, to meet clinical needs. However, the existing collagen membrane freeze-drying molds are all single-layer freeze-drying molds and cannot form a double-layer collagen membrane. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a double-layer collagen membrane freeze-drying mold.

[0005] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0006] A double-layer collagen membrane freeze-drying mold comprises a base, a frame plate 1 and a support plate are provided on the top of the base, a top plate is fixed in the middle of the side of the support plate, a frame plate 2 is provided on the top plate, a mounting groove is provided in the middle of the top plate, slide grooves are provided on both sides of the mounting groove, a mounting plate is provided in the mounting groove, slide bars matching the slide grooves are provided on both sides of the mounting plate, and a clamping mechanism matching the frame plate 2 and the frame plate 1 is provided on the top of the side of the support plate.

[0007] Furthermore, the clamping mechanism includes a fixed plate fixed on the side of the support plate, a support frame is fixed to one side of the top of the fixed plate, a rotating plate is movably connected to the top of the support frame, a traction rope is provided at the other end of the rotating plate, a hook is provided at the other end of the traction rope, and a hanging ring matching the hook is provided at the top of the base.

[0008] Furthermore, a sliding sleeve is slidably connected to the rotating plate, and a vertical plate is movably connected to the outer surface of the sliding sleeve. The bottom end of the vertical plate passes through the bottom of the fixed plate and is connected and fixed to a pressure plate. The pressure plate cooperates with both the frame plate 2 and the frame plate 1.

[0009] Furthermore, the fixed plate is provided with a through hole matching with the vertical plate, protrusions are fixed on both sides of the through hole, spring grooves are provided on both sides of the outer surface of the vertical plate, springs are provided on both sides of the spring groove, and the other end of the spring is squeezed together with the protrusion.

[0010] Furthermore, a limiting hole penetrating into the interior of the slide groove is opened at the top of the top plate, a limiting groove matching with the limiting hole is opened at the top of the slide bar, a limiting rod is inserted into the limiting hole, and the bottom end of the limiting rod penetrates into the limiting groove.

[0011] Furthermore, the top of the mounting plate and the top of the top plate are located in the same horizontal plane, and the space enclosed by the mounting plate and the frame plate cooperates with each other.

[0012] Beneficial effects of the utility model:

[0013] Through the detachable design of the top plate and the mounting plate, when producing the collagen membrane, the top plate and the mounting plate can be matched together to form a flat surface, which can provide a support surface for the frame plate 2. When the two collagen membranes need to be pressed together, the mounting plate can be pulled out so that the two collagen membranes can be fitted together. At the same time, it is also convenient for the pressing mechanism to enter from the mounting groove into the interior of the frame plate 1 to press the two collagen membranes together.

[0014] Through the design of the clamping mechanism, when the two collagen membranes need to be compressed, the rotating plate can be pressed down, and the rotating plate descends to squeeze the sliding sleeve, so that the sliding sleeve drives the vertical plate to descend, and the vertical plate descends and drives the pressing plate to descend at the same time. When the pressing plate descends, it enters into the interior of the frame plate through the installation groove to press the two collagen membranes together.

[0015] Through the design of the traction rope, the hook and the hanging ring, the rotating plate that rotates downward can be limited, and then the pressing plate that presses down can be indirectly limited, so that the two collagen membranes can be subjected to stable and continuous pressure, so that the two collagen membranes can be tightly pressed together.

[0016] By designing the limiting rod, the limiting hole and the limiting groove, the top plate and the mounting plate can be limited together when the mounting plate is inserted into the mounting groove.

[0017] Through the design of the spring, power can be provided for the rotation and reset of the rotating plate. BRIEF DESCRIPTION OF THE DRAWINGS
