[0002] With the improvement of modern medical level and people's higher requirements for wound healing quality, traditional wound dressings are gradually unable to meet clinical needs in many aspects. For example, although ordinary gauze dressings have good air permeability, they have poor moisture retention and are easy to adhere to the wound, which can easily cause secondary damage during dressing changes. Hydrogel dressings have good hydrophilicity, can absorb wound exudate and keep the wound moist, help promote cell migration and granulation tissue growth, thereby accelerating wound healing. They have broad application prospects in the care of various types of wounds such as burns, chronic ulcers, and postoperative wounds, making their market demand continue to rise;

[0003] During the stirring process, the various raw materials of the existing medical hydrogel dressings are stirred by rotating a stirring rod at a fixed angle, so that the various raw materials cannot be fully mixed, resulting in an imbalance in local concentrations. The final hydrogel dressing has component ratios in different parts that do not meet expectations, affecting the consistency of product performance. At the same time, after the mixing reaction of the various raw materials of the existing medical hydrogel dressings is completed, it is impossible to effectively filter out unreacted impurities, particles and other substances inside, thereby reducing the purity and safety of the product.

[0025] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] like Figure 1 As shown, a bottom plate 20 is fixedly connected to the lower surface of the filter box 2, and a plurality of supporting legs 21 are fixedly connected to the lower surface of the bottom plate 20;

[0028] The bottom plate 20 and the plurality of supporting legs 21 can provide reliable support for the entire hydrogel dressing preparation device, so that it can maintain a stable state during operation, thereby ensuring the stability of the hydrogel dressing preparation.

[0029] like Figure 1 and Figure 2 As shown, a preparation device for medical hydrogel dressing is provided, comprising a stirring box 1, a filter box 2 is fixedly connected to the lower surface of the stirring box 1, a feed pipe 3 is integrally formed on the left side of the upper surface of the stirring box 1, a control box 4 is fixedly connected to the left sides of the stirring box 1 and the filter box 2, a stirring chamber 5 is integrally formed inside the stirring box 1, a drive motor 6 is fixedly connected to the left side inside the control box 4, a hollow rod 7 is fixedly connected to the right end of the output shaft of the drive motor 6, a transmission chamber 8 is integrally formed inside the stirring box 1 and on the right side of the stirring chamber 5, the right end of the hollow rod 7 extends to the inside of the transmission chamber 8, a through-type slide groove 9 is opened on the front surface of the inner side wall of the hollow rod 7, a sliding tube 10 is sleeved on the outer side wall of the hollow rod 7, and a plurality of stirring blades 11 are fixedly connected to the outer side wall of the sliding tube 10;

[0030] First, various raw materials required for the hydrogel dressing are installed in a certain proportion and placed into the stirring chamber 5 through the set feeding pipe 3, and then the set driving motor 6 is started to control the rotation of the hollow rod 7. The hollow rod 7 drives the multiple stirring blades 11 to rotate through the set sliding tube 10, so that the raw materials can be stirred and mixed by the multiple stirring blades 11.

[0031] like Figure 1 and Figure 2 As shown, the inner wall of the feed pipe 3 is threadedly connected with a sealing cover 42;

[0032] The sealing cover 42 can effectively block and seal the feed pipe 3 after the raw materials are added into the stirring chamber 5, preventing dust, microorganisms, etc. from mixing into the raw materials being added, thereby ensuring the purity of the ingredients of the hydrogel dressing and thus ensuring its safety and effectiveness in medical applications.

[0033] like Figure 2 and Figure 3As shown, the outer wall of the hollow rod 7 and the interior of the transmission chamber 8 are fixedly connected with a bevel gear 12, the inner right side of the transmission chamber 8 is rotatably connected with a bevel gear 2 13, the upper surface of the inner wall of the transmission chamber 8 is fixedly connected with a fixed rod 14, the bottom end of the fixed rod 14 is rotatably connected with a bevel gear 3 15 through a rotating shaft, the outer wall of the bevel gear 3 15 is meshed with the outer wall of the bevel gear 2 13 and the outer wall of the bevel gear 1 12 respectively, a rotating rod 16 is fixedly connected at the left center of the bevel gear 2 13, the left end of the rotating rod 16 is rotatably connected with the inner left side of the hollow rod 7, the outer wall of the rotating rod 16 and the interior of the hollow rod 7 are integrally formed with a cam groove 18, the inner wall of the sliding tube 10 is fixedly connected with a limiting slider 19, the rear end of the limiting slider 19 passes through the slide groove 9, and is slidably connected with the inside of the cam groove 18;

[0034] When the hollow rod 7 is driven to rotate by the set driving motor 6, the rotation of the hollow rod 7 will drive the bevel gear 12 at its right end to rotate at the same time. The bevel gear 12 controls the rotation of the bevel gear 2 13 through the set bevel gear 3 15. The rotation of the bevel gear 2 13 can control the rotation of the rotating rod 16. When the rotating rod 16 rotates, the cam groove 18 also makes a circular motion, so that the limit slider 19 will slide in the cam groove 18. Under the constraint of the cam groove 18, the limit slider 19 will drive the sliding tube 10 to reciprocate along the slide groove 9. Therefore, the sliding tube 10 drives the multiple stirring blades 11 to rotate and stir, and also drives the multiple stirring blades 11 to move back and forth laterally inside the stirring chamber 5, so that the multiple stirring blades 11 can stir the raw materials in the stirring chamber 5 more comprehensively and fully.

[0035] like Figure 2 As shown, the outer wall of the hollow rod 7 is symmetrically fixedly connected to a connecting rod 45 located inside the stirring chamber 5, and the bottom ends of the two connecting rods 45 are fixedly connected to a scraper 46, and the outer wall of the scraper 46 is in contact with the inner wall of the stirring chamber 5;

[0036] When the hollow rod 7 rotates to control the multiple stirring blades 11 to stir the raw materials, due to factors such as the viscosity of the raw materials, some of the raw materials are easily attached to the inner wall of the stirring chamber 5. As the stirring continues, if these attached raw materials are not cleaned in time, they will accumulate more and more, which will not only cause waste of raw materials, but also may affect the quality of subsequent batches of products, leading to problems such as deviation in the proportion of ingredients. The scraper 46 can be used to scrape off the raw materials attached to the inner wall of the stirring chamber 5, so that they return to the stirring area to participate in mixing, thereby ensuring the full utilization of the raw materials and the consistency of the ingredients of each batch of products.

[0037] like Figure 2As shown, a frame 23 is provided inside the filter box 2, a filter screen 24 is provided on the lower surface of the frame 23, a plurality of through-type circular holes 25 are provided on the lower surface of the inner part of the stirring chamber 5, and electromagnetic valves 26 are provided inside the plurality of circular holes 25, and a discharge pipe 27 is integrally formed at the lower right side of the filter box 2;

[0038] When the raw materials in the stirring chamber 5 are fully stirred and mixed, the multiple electromagnetic valves 26 are opened to allow the raw materials to be transported to the inside of the filter box 2 through the multiple circular holes 25. At the same time, the multiple stirring blades 11 continue to rotate to control the rotation of the scraper 46 to scrape off the raw materials attached to the inside of the stirring chamber 5. Then, the hydrogel components with a particle size smaller than the aperture of the filter screen 24 and the liquid components therein can pass through the filter screen 24 smoothly and penetrate into the lower space of the filter box 2, while the impurities with a particle size larger than the aperture of the filter screen 24 are intercepted above the filter screen 24, thereby achieving the filtration and purification of the hydrogel dressing material, improving the purity of the product, and removing the impurities that may affect the quality and safety of the product. Finally, the filtered hydrogel can be transported to the outside through the discharge pipe 27 through the sloped design of the lower part of the filter box 2 for shaping and other processing steps.

[0039] like Figure 2 , Figure 4 and Figure 5 As shown, the left and right sides of the filter box 2 are integrally formed with sliding chambers 28, the interiors of the two sliding chambers 28 are slidably connected with piston plates 29, the opposite sides of the two piston plates 29 are fixedly connected with movable plates 30, the opposite ends of the two movable plates 30 are rotatably connected to the left and right sides of the frame 23 respectively through rotating shafts, the inner lower surface of the control box 4 is fixedly connected with an electric telescopic rod 31, the top end of the output shaft of the electric telescopic rod 31 is fixedly connected with a movable plate 32, the upper surface of the movable plate 32 is fixedly connected with an extrusion box 33, the inner upper surface of the extrusion box 33 is integrally formed with a through-type giving way groove 34, the interior of the extrusion box 33 is slidably connected with a piston plate 23, and the movable plate 30 is fixedly connected with the piston plate 23. The upper surface of the plug plate 35 is rotatably connected to a connecting plate 36 via a rotating shaft, the top of the connecting plate 36 passes through the clearance groove 34, the outer wall of the hollow rod 7 and the main gear 37 is fixedly connected inside the control box 4, the right side of the extrusion box 33 is fixedly connected to an L-shaped support plate 38, the upper left side of the L-shaped support plate 38 is rotatably connected to a slave gear 39, the lower left side of the slave gear 39 is rotatably connected to the upper right side of the connecting plate 36 via a rotating shaft, the lower inner surface of the extrusion box 33 and the inside of the sliding chamber 28 on the left side of the filter box 2 are fixedly connected to a gas hose 40, and a plurality of through-type pressure relief holes 43 are provided on the right side of the sliding chamber 28 on the right side of the filter box 2;

[0040] When the multiple electromagnetic valves 26 are opened to allow the raw materials to be transported to the interior of the filter box 2 through the multiple circular holes 25, the main gear 37 will also rotate when the hollow rod 7 rotates. Then, the moving plate 32 is controlled to slide upward by controlling the extension of the electric telescopic rod 31. When the moving plate 32 moves, it will also drive the extrusion box 33 and the L-shaped support plate 38 to move upward together, so that the slave gear 39 can be moved to the bottom of the main gear 37, so that the slave gear 39 is controlled to rotate repeatedly by the main gear 37, and the slave gear 39 rotates through the provided connecting plate 36 to control the piston plate 2 35 to slide up and down inside the extrusion box 33. The piston plate 1 29 moves simultaneously, and the two piston plates 1 29 can control the frame 23 and the filter screen 24 to move back and forth through the movable plate 30, thereby making the impurities accumulated on the filter screen 24 relatively loose, preventing them from being over-compacted and clogging the filter screen 24, so that more hydrogel materials blocked by impurities can be filtered through the filter screen 24, thereby improving the filtering efficiency.

[0041] like Figure 5 As shown, a limit frame 17 is fixedly connected inside the control box 4 and above the movable plate 32;

[0042] The limit frame 17 can effectively limit the sliding height of the movable plate 32, ensuring that the upper internal components of the control box 4 can always maintain stable operation, thereby providing an effective power source for the filter screen 24 to move back and forth.

[0043] like Figure 1 As shown, a control center 44 is provided on the right side of the mixing box 1;

[0044] The control center 44 is provided to facilitate operators to control the operation of the equipment in an intelligent and programmed manner.

[0045] like Figure 1 As shown, the front surface of the mixing box 1 is integrally formed with an observation window 22, and the front surface of the filter box 2 is rotatably connected with a sealing door 41 through a hinge;

[0046] The observation window 22 is provided to facilitate the operator to observe the mixing status of the raw materials inside the stirring chamber 5 in real time. At the same time, the sealing door 41 is provided to facilitate the operator to disinfect and clean the inside of the filter box 2 or remove and clean the filter screen 24 to ensure that the device can be reused later.

[0047] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
