Problems solved by technology

[0002] Knee joint inflammation is a common clinical disease. The main symptoms are redness and swelling of the knee, knee soreness, knee joint snapping, etc. Knee joint stiffness and chills are also one of the symptoms of knee joint inflammation. By applying medicine to the knee joint Sticking the medicine into the skin and joints to treat knee joint inflammation is a commonly used method at present. Since the knee joint is a movable joint, the medicine application paste is usually not firm and not durable. In addition, the cold of the knee joint is the cause of knee joint inflammation A very important reason is that there are various dressings and protective devices developed based on knee health care on the market, which can keep warm and generate heat, but basically have no auxiliary effect of drug treatment.

Embodiment 1

[0027] figure 1 It is a schematic diagram of the structure of the dressing material for knee joint inflammation of the present invention. As shown in the figure, the dressing material includes a bionic support part 1 and a functional lining 2, and is used in conjunction with a drug patch 3. The bionic support part 1 is The solid shell material 3D printed according to the human knee joint data model, the functional lining 2 is a flexible lining material with a certain thickness 3D printed inside the bionic support part 1, the flexible lining The material is a flexible grid structure or a flexible braided structure, and the drug patch 3 is laid on the inner side of the functional liner 2 for attachment to the knee joint of a human body.

[0028] The method for preparing the above-mentioned dressing material by 3D printing includes:

[0029] Step S1: Use a 3D scanner to collect the user's knee information to obtain knee features; when collecting the user's knee information in th...

Embodiment 2

[0041] This embodiment is a further example of the 3D printing process used to print the bionic support part 1 and the functional lining 2. As mentioned above, in addition to fused deposition modeling, laser selective melting and photocuring molding are also preferred solutions. Specifically, Selective laser melting and photo-curing molding have more accurate profiling accuracy when manufacturing the bionic support part 1, and also have a higher success rate than fused deposition molding when preparing a grid structure with a certain design shape (not a simple weaving structure). Therefore, this embodiment adopts laser selective melting or photocuring molding to implement manufacturing. In specific manufacturing, laser selective melting or photocuring molding can be directly used to complete the preparation of the entire covering material, and laser selective melting or photocuring molding A grid with a lattice structure is produced by means of a method as the structure of the ...

Abstract

A dressing material for knee joint inflammation, used in conjunction with drug patches, including a bionic support part and a functional lining. The bionic support part is a solid shell material that is 3D printed according to the human knee joint data model, and the functional lining It is a flexible lining material with a certain thickness that is 3D printed on the inner side of the bionic support part. The flexible lining material is a flexible mesh structure or a flexible weaving structure. Attached, preferably, at least the material of the functional liner includes a functional material, the functional material preferably includes a gold-silver core-shell nanomaterial, and the functional liner can include a high-porosity first liner and a low-porosity second liner . According to the principle of bionics, the present invention utilizes the moldless and rapid prototyping characteristics of 3D printing to manufacture non-disposable dressing materials, which are used in conjunction with conventional disposable drug patches to protect and treat knee joints and provide good sticking effects. It also helps the medicine work.

Description

technical field [0001] The invention relates to the technical field of 3D printing of medical materials, in particular to a dressing material for knee joint inflammation. Background technique [0002] Knee joint inflammation is a common clinical disease. The main symptoms are redness and swelling of the knee, knee soreness, knee joint snapping, etc. Knee joint stiffness and chills are also one of the symptoms of knee joint inflammation. By applying medicine to the knee joint Sticking the medicine into the skin and joints to treat knee joint inflammation is a commonly used method at present. Since the knee joint is a movable joint, the medicine application paste is usually not firm and not durable. In addition, the cold of the knee joint is the cause of knee joint inflammation A very important reason is that there are various dressings and protectors developed based on knee health care on the market, which can keep warm and generate heat, but basically have no auxiliary effec...
