Problems solved by technology

[0003] Although there are many kinds of knee orthoses, the upper and lower brackets can only rotate in one plane, which limits the human calf and thigh to only swing in one direction during use.
In actual situations, there are differences in the degree of knee joint deformity among patients, and the human calf rotates internally and externally relative to the thigh during exercise. As a result, the existing knee orthosis cannot be applied to some patients with large knee joint deformity. Due to the restriction of the internal and external rotation of the calf relative to the thigh, the user experience is poor
However, if the internal and external rotation of the calf relative to the thigh is not restricted, the resulting lateral twisting force may further aggravate the knee joint injury of the patient

Embodiment 1

[0040] Example 1: Preparation of PEGylated Oleanolic Acid / Magnolol Sustained Release Agent

[0041] The PEGylated oleanolic acid was dissolved in a mixed solution of propylene glycol: water = 1:3 to prepare a 5 mg / mL solution. Magnolol was dissolved in a mixed solution of propylene glycol: water = 1:3 to prepare a 5 mg / mL solution. The substrate was soaked in the above magnolol solution for 15 minutes, washed with water for 5 minutes, then soaked in PEGylated oleanolic acid solution for 15 minutes, and washed with water for 5 minutes. This alternate deposition process was repeated to obtain a PEGylated oleanolic acid / magnolol film.

Embodiment 2

[0042] Embodiment 2: Research on release kinetics in vitro

[0043] The PEGylated oleanolic acid / magnolol film obtained in Example 1 was soaked in a phosphate buffer solution for in vitro release experiments. Use 900mL of pH 5.8 phosphate buffer solution as the release medium, the rotation speed is 50 rpm, the temperature of the water bath is 37°C, sample 10mL every 100min, and at the same time supplement the release medium at the same temperature and volume, take out the sample release solution with a 0.45μm micrometer Pore ​​membrane filtration, take the subsequent filtrate as the test sample solution. Detect the concentration of PEGylated oleanolic acid in phosphoric acid buffer solution with high performance liquid chromatography, obtain the release kinetics curve of PEGylated oleanolic acid as follows figure 1 shown. It can be seen that the PEGylated oleanolic acid is always released at a constant rate, without burst release, and can be completely released.

Embodiment 3

[0044] Embodiment 3: the effectiveness experiment of pharmaceutical composition

[0045] 50 cases were selected, aged 40-70 years, 23 males and 27 females, 25 people in each group. Both groups of patients had similar degree of muscle soft tissue swelling and joint pain.

[0046] Treatment group: the drug slow-release preparation of this embodiment was applied to the affected area once a day for 7 consecutive days, and the effect on the 7th day and before treatment was observed.

[0047] Control group: Apply commercially available common joint pain relief ointment to the affected area, once a day, for 7 consecutive days, and observe the effect on the 7th day and before treatment.

[0048] Evaluation method: It is divided into three grades: cured, markedly effective, and ineffective. Cure: the swelling subsides completely, and the pain disappears; markedly effective: the swelling subsides obviously, and the pain relieves; ineffective: the swelling subsides not obviously, and th...

Abstract

The invention relates to the field of medical apparatuses, in particular to a knee joint orthotics capable of preventing lateral twisting force. The knee joint orthotics comprises a thigh supporting frame, a shank supporting frame, a first thigh supporting bar, a second thigh supporting bar, a first shank supporting bar and a second shank supporting bar, the first thigh supporting bar is rotatablyconnected with the first shank supporting bar, and the second thigh supporting bar is rotatably connected with the second shank supporting bar; a groove transversely penetrating through the shank supporting frame is formed above the shank supporting frame and is internally provided with a slide bar capable of sliding left and right in the groove, connecting sections extend to both ends of the slide bar, and threaded columns are arranged at the ends of the connecting sections; openings capable of sleeving the connecting sections of the slide bar are formed in the ends of the first shank supporting bar and the second shank supporting bar, springs further sleeve the portions, between the first shank supporting bar or the second shank supporting bar and the slide bar, on the connecting sections, and nuts are screwed on the threaded columns. By the adoption of the structure, on the condition that it is allowed that the shanks generate certain inward rotation and outward rotation, injuriesto the knee can also be effectively prevented when the distortion amplitude is too large, and the distortion time is long.

Description

technical field [0001] The invention belongs to rehabilitation physiotherapy equipment among medical instruments, in particular to a knee joint orthosis capable of preventing lateral twisting force. Background technique [0002] The knee joint is one of the important load-bearing joints of the lower limbs of the human body. In today's society, the internal structure of the knee joint is damaged due to external shocks or degenerative diseases, such as ligament damage, cartilage degeneration, and meniscus wear, which eventually lead to knee joint pain in patients. There are more and more cases of movement disorders, and knee orthoses for different lesions or injuries are also produced. [0003] Although there are many kinds of knee orthoses, the upper and lower brackets can almost only rotate in one plane, which limits the human calf and thigh to swing in one direction only during use. In actual situations, there are differences in the degree of knee joint deformity among pat...
