Embodiment 1

[0019] The arm bracket structure provided by the invention is as figure 1 As shown, it is composed of an upper arm support 1 and a forearm support 2. A position adjustment plate 3 is arranged at one end of the upper arm support 2. A plurality of limit cards 4 are arranged on the position adjustment plate 3. On the upper arm support 2, there are also The runner 6 and the runner 5 are movably connected with the forearm support 2, and the lower part of the forearm support 2 is provided with a support rod 5. When the support rod 5 is clamped on different limit cards 4, the upper arm support 1 and the forearm support 2 can be realized. maintain different angles. When in use, place the upper arm and the front wall on the upper arm support 1 and the forearm support 2 respectively, and adjust the angle between the two to meet different placement requirements.

[0020] Both the upper surfaces of the upper arm support 2 and the forearm support 2 are concave; they can better fit the ext...

example 1

[0027] (1), by weight, 7 parts of chitosan were dissolved in 2wt% dilute acetic acid aqueous solution to form 7wt% chitosan acetic acid aqueous solution;

[0028] (2) Heat the chitosan acetic acid aqueous solution in step (1) to 75°C under mechanical stirring, add 1 part of initiator potassium persulfate and keep it warm for 40 minutes, then add 10 parts of acrylic acid monomer to continue the reaction for 5 hours to obtain a reaction solution ;

[0029] (3), add 20 parts of ethanol to the reaction solution obtained in step (2), filter with suction, wash the obtained filter cake twice with ethanol, dry at 50°C, and then pulverize to obtain a pulverized dry product;

[0030] (4) Take 80 parts of mustard seeds, add 200 parts of water to heat and extract, filter the extract and spray dry to obtain mustard seed extract;

[0031] (5) Add 15 parts of dimethyl sulfoxide to the pulverized dry product obtained in step (3), stir and disperse evenly, then add 1 part of diisopropylcarbod...

example 2

[0035] The difference from Example 1 is that the microcrystalline cellulose is not modified in step (7), that is, polyethylene glycol is not added in step (6).

[0036] The resulting hydrogels were tested as follows:

[0037] (1) Gel strength: use the Lloyd material testing machine to measure the force required to penetrate the starch gel to a certain depth. When the gel is broken, the force applied by the probe to the gel is defined as the gel strength;

[0038] (2) Antibacterial performance: according to the antibacterial test method FZ / T01021-92 in the 1992 disinfection technical specification of the Ministry of Health;

[0039] (3) Wound healing experiment: male Wistar rats were used as experimental animals, and the observation points were 3, 5, 10, and 18 days after injury. The back of the rat was depilated with 8% sodium sulfide solution, anesthetized after 24 hours, and then scalded in an 80°C water bath for 15 seconds to cause deep second-degree skin scald on 10% of t...

Abstract

The invention relates to an arm bracket after hand surgery, belonging to the technical field of medical equipment. The arm bracket comprises an upper arm bracket and a forearm bracket, wherein a position adjusting plate is arranged at one end of the upper arm bracket; multiple limiting clips are arranged on the position adjusting plate; a turning wheel is also arranged on the upper arm bracket and is movably connected with the forearm bracket; a support rod is arranged below the forearm bracket; when the support rod is clamped on different limiting clips, different angles can be kept between the upper arm bracket and the forearm bracket; and hydrogel blocks are arranged on the upper surfaces of the upper arm bracket and the forearm bracket.

Description

technical field [0001] The invention relates to an arm support after surgery, and belongs to the technical field of medical instruments. Background technique [0002] Clinically, hand surgery patients with hand and forearm injuries or after surgery have severe limb swelling, and need to elevate the affected limb, and some need to observe blood supply. Nursing methods usually adopted after surgery include: 1. Routine nursing after brachial plexus or general anesthesia; Swelling; patients undergoing microsurgery must stay in bed for 10-14 days; 3. Closely observe the skin color, temperature, swelling, sensory movement and incision bleeding of the fingertips. [0003] CN204379641U discloses a nursing bracket for hand surgery, including a support plate and a support frame, the support plate is concave inward in an arc shape, the inner surface of the support plate is provided with a soft pad, and one end of the support plate is provided with a support portion , the other end ...
