Description

Technical Field

[0001] This invention relates to the field of colloidal material preparation technology, specifically to a preparation process and equipment for a medical cosmetic repair gel. Background Technology

[0002] Medical cosmetic repair gel is mainly used for wound repair and care. It is primarily a gel material, usually prepared by combining hydrogel, moisturizer, and traditional Chinese medicine preparation liquid. When used, it replaces the traditional gauze and is applied to the wound site to form a disinfecting barrier film that adheres to the wound. It not only has antibacterial properties but also absorbs wound secretions, reduces the probability of wound infection, relieves patient pain, and effectively accelerates wound healing.

[0003] In existing medical cosmetic repair gel preparation processes, the mixing of various raw materials is relatively concentrated, failing to classify and premix the various materials according to their state before extracting each category of materials in proportion for final mixing. Current cosmetic gel preparation processes typically involve storing each category of materials in proportion during final mixing, followed by overall stirring. Furthermore, because the overall material is in a gel-like state, the stirring efficiency is low, easily leading to low preparation efficiency for existing cosmetic repair gels. Summary of the Invention

It has the advantages of pre-mixing various materials according to their state, and then mixing the pre-mixed materials in proportion.

[0008] 3) Extract the traditional Chinese medicine preparation liquid, gel matrix and moisturizer respectively in a weight ratio of 5-15:0.2-15:8-35 and inject them into the main mixing chamber. At the same time, inject 30%-75% distilled water into the main mixing chamber.

[0009] 4) Stir in the main mixing chamber for 25 to 60 minutes, then discharge the material.

[0029] The beneficial effects of the preparation process of the medical cosmetic repair gel of the present invention:

[0030] The preparation process of this medical cosmetic repair gel involves pre-mixing and stirring the materials separately, ensuring the uniformity of the mixing of raw materials of different properties, and avoiding sedimentation or stratification. Pre-mixing the raw materials before the main mixing maintains the uniformity of the classified raw materials, ensuring the quality of the prepared medical cosmetic gel. Furthermore, the classification process, which separates the raw materials into categories within a single overall process before main mixing, facilitates streamlined operations, effectively reducing the overall difficulty of the preparation process and improving the efficiency of the medical cosmetic gel.

[0031] The beneficial effects of the equipment for preparing the medical cosmetic repair gel of the present invention:

[0032] This equipment for preparing medical cosmetic repair gel uses a drive component to control the rotation of the inner moving tank and stirring shaft, achieving simultaneous and separate stirring of materials in three stirring chambers. This effectively improves work efficiency. Furthermore, by stirring the materials separately before the main mixing, it effectively avoids unevenness between the different categories of materials before the main mixing, thus ensuring the quality of the medical cosmetic repair gel obtained through the main mixing process.

[0033] The equipment for preparing this medical cosmetic repair gel uses an inner eccentric shaft to drive a movable mesh plate to rotate. The mesh openings of the movable mesh plate are used to squeeze and mix the gel inside the main shell, thus avoiding the influence of the high viscosity of the gel on the mixing process. This effectively improves the mixing effect and efficiency of the gel. At the same time, when the mesh openings of the movable mesh plate are closed, the mesh plate, which facilitates the closing of the mesh openings, squeezes and discharges the gel inside the main shell, effectively ensuring the discharge of the gel and avoiding the generation of a large amount of gel residue inside the main shell. This facilitates the complete discharge of the gel and thus effectively ensures the performance of the device. Attached Figure Description

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Example 1

[0048] This embodiment is the first embodiment of the present invention, which is a preparation process of a medical cosmetic repair gel, the steps of which include:

[0049] 1) Pre-prepared traditional Chinese medicine preparation solution, gel matrix, and humectant;

[0050] 2) The traditional Chinese medicine preparation solution, gel matrix and humectant are injected into the first stirring chamber, the second stirring chamber and the third stirring chamber respectively for separate premixing, and the stirring time is 15 min to 45 min;

[0051] 3) Extract the traditional Chinese medicine preparation liquid, gel matrix and moisturizer respectively in a weight ratio of 5-15:0.2-15:8-35 and inject them into the main mixing chamber. At the same time, inject 30%-75% distilled water into the main mixing chamber.

[0052] 4) Stir in the main mixing chamber for 25 to 60 minutes, then discharge the material.

[0053] Specifically, the traditional Chinese medicine preparation solution includes the following ingredients: 12%–22% of *Gynostemma pentaphyllum*, 18%–22% of *Lonicera japonica*, 8%–16% of *Taraxacum mongolicum*, 8%–16% of *Impatiens balsamina*, 10%–18% of licorice, 10%–18% of *Cnidium monnieri*, 12%–22% of borneol, and 8%–18% of *Rhus chinensis*.

[0054] Take the following herbs in the specified proportions: golden sand vine, honeysuckle vine, dandelion, balsam flower, licorice, cnidium fruit, borneol, and gallnut. Add water and decoct at least twice, each time for 1 to 3 hours. Filter and collect the filtrate. Concentrate the filtrate under low temperature and reduced pressure to 1.6 to 1.7 g / ml of raw herbs.

[0055] Specifically, the main components of the gel matrix include 0.8%–1.8% carbomer, 3.5%–15% cellulose derivatives, 1.8%–3.6% alginate, 8%–17% polyethylene glycol, 10%–26% gelatin, 0.6%–2.2% chitosan, 0.8%–2.3% acrylic resin, and 22%–35% polyvinyl alcohol;

[0056] Moisturizers include one or more of glycerin, propylene glycol, sorbitol, polyethylene glycol, and butylene glycol.

[0057] In summary, by injecting the herbal preparation solution, gel matrix, and humectant into the first, second, and third mixing chambers respectively for separate pre-mixing, the raw materials are pre-treated separately. This ensures the uniformity of the mixture of raw materials with different properties, preventing precipitation or stratification. Inconsistent raw material composition during the mixing and injection of raw materials for medical cosmetic gel preparation can negatively impact the quality of the gel. Therefore, pre-mixing the raw materials before main mixing maintains the uniformity of the classified raw materials, ensuring the quality of the medical cosmetic gel. Furthermore, by classifying the raw materials for processing within a single overall process, and then using the classified raw materials for main mixing, streamlined operations are facilitated, effectively reducing the overall difficulty of the medical cosmetic gel preparation process and improving its efficiency.

[0058] Example 2

[0059] Please see Figure 1 and Figure 11 This embodiment is the second embodiment of the present invention, used in the mixing and stirring steps required in the preparation process of medical cosmetic repair adhesive. Specifically, it is a preparation device for medical cosmetic repair adhesive, including a support base 10. The top of the support base 10 is provided with a premixing mechanism 20 and a main mixing mechanism 30, which are interconnected. A material lifting mechanism 40 is fixedly installed on the outside of the support base 10.

[0060] The material lifting mechanism 40 is located near the premixing mechanism 20 and is used to inject raw materials from the raw material barrel or transition barrel into the premixing mechanism 20. The material lifting mechanism 40 is used for moving and lifting the raw material barrel or transition barrel.

[0061] The material lifting mechanism 40 includes a movable guide rail 41 fixedly connected to the outside of the support base 10, a movable bracket 42 movably connected to the top of the movable guide rail 41, a lifting platform 43 slidably connected to the outside of the movable bracket 42, and a fixed mechanical arm 44 for fixing the raw material barrel or the transition barrel is provided between the lifting platforms 43.

[0062] The movable guide rail 41 is equipped with a sliding drive for controlling the sliding of the movable support 42, and the movable support 42 is equipped with a lifting drive for controlling the lifting of the lifting platform 43. The fixed robotic arm 44 consists of a clamping plate and a threaded rod, with the threaded rod threadedly connected to the lifting platform 43. The sliding drive is a cylinder drive, and the lifting drive is a chain and hydraulic cylinder drive.

[0063] When mixing materials, the material bucket can be placed upside down on the lifting platform 43. The lifting platform 43 is equipped with a discharge port, which is equipped with a control valve block for controlling its opening and closing.

[0064] When the material bucket is placed, the threaded rod of the fixed mechanical arm 44 is turned, and the threaded rods on both sides push the clamping plate to fix and hold the material bucket, so that the material bucket is fixed on the lifting platform 43. The lifting platform 43 is controlled to move upward, so that the position of the material bucket is higher than that of the premixing mechanism 20.

[0065] Then push the movable support 42 closer to the premixing mechanism 20. When the movable support 42 moves to the appropriate position, control the lifting platform 43 to move downward so that the material bucket connects with the feed port 24 of the premixing mechanism 20.

[0066] Repeat the above steps until all materials are classified and injected into the premixing unit 20.

[0067] It also includes classifying and placing various materials into a transition bucket, inverting and fixing the transition bucket on the lifting platform 43, and injecting the materials from the transition bucket into the premixing mechanism 20 at once.

[0068] Example 3

[0069] Please see Figure 2-5 The difference from the previous embodiment lies in the premixing of materials. Specifically, the premixing mechanism 20 includes an outer shell 21, with an inner movable barrel 22 rotatably connected inside the outer shell 21. The inner movable barrel 22 has three stirring chambers. A movable cover 23 is fixedly connected to the top of the inner movable barrel 22. The movable cover 23 is adapted to the three stirring chambers and is provided with three feed ports 24 respectively. Rotating stirring shafts 25 are respectively provided in the three stirring chambers of the inner movable barrel 22. A drive assembly for driving the inner movable barrel 22 and stirring shafts 25 to rotate is provided at the bottom of the inner movable barrel 22 and the stirring shafts 25. A feeding mechanism is provided at the bottom of the inner movable barrel 22. The feeding mechanism is used to inject the materials from the three stirring chambers of the inner movable barrel 22 into the main mixing mechanism 30 respectively.

[0070] The three mixing chambers are configured as a first mixing chamber, a second mixing chamber, and a third mixing chamber, which are used to store classified medical cosmetic repair adhesive materials. The materials are mixed by rotating and stirring in the first mixing chamber, the second mixing chamber, and the third mixing chamber through a set stirring shaft 25.

[0071] The drive assembly is used to drive the inner movable barrel 22 to rotate inside the outer shell 21, and at the same time drive the stirring shafts 25 inside the three stirring chambers to rotate.

[0072] The drive assembly includes a sun gear 28, a planet gear 27, and an external gear ring 29. The external gear ring 29 is fixedly connected inside the outer shell 21. A positioning frame 26 for support is provided outside the planet gear 27 and the sun gear 28. The positioning frame 26 is rotatably connected to the outer shell 21. The planet gear 27 is meshed between the sun gear 28 and the external gear ring 29. A drive motor for driving the rotation of the sun gear 28 is provided outside the sun gear 28. The drive motor is a low-speed motor.

[0073] The stirring shaft 25 passes through the inner movable barrel 22 and is fixedly connected to the shaft of the planetary gear 27;

[0074] The working process of the drive assembly driving the inner movable tank 22 and the stirring shaft 25 is as follows:

[0075] The drive motor is located at the bottom of the outer casing 21 and is fixedly mounted on the top of the support base 10. The drive motor drives the sun gear 28 to rotate, and the sun gear 28 drives the planet gear 27 to rotate. Since the planet gear 27 meshes inside the outer gear ring 29, when the planet gear 27 rotates, the planet gear 27 rotates inside the outer gear ring 29. At the same time, the planet gear 27 drives the stirring shaft 25 to rotate, and under the action of the planet gear 27, the planet gear 27 drives the inner movable barrel 22 to rotate inside the outer casing 21.

[0076] When the planetary gear 27 rotates, the positioning frame 26 is used to support the planetary gear 27. At the same time, the positioning frame 26 is also used to assist in supporting the inner movable barrel 22 to rotate inside the outer shell 21. When the planetary gear 27 rotates around the star gear 28, the positioning frame 26 rotates with the planetary gear 27.

[0077] The drive motor controls the rotation of the inner movable tank 22 and the stirring shaft 25 via the drive assembly, achieving synchronous and separate stirring of the materials inside the three stirring chambers. This effectively improves work efficiency. Furthermore, by stirring the materials separately before the main mixing, it effectively avoids unevenness in the different categories of materials before the main mixing. This, in turn, ensures the quality of the medical cosmetic repair gel obtained through the main mixing.

[0078] Upon completion of mixing, the material from each mixing chamber needs to be injected into the main cavity of the main housing 31 via the injection mechanism. Specifically:

[0079] The injection mechanism includes an annular plunger pump 212, and discharge pipes 210 fixedly connected to the bottom of the three mixing chambers of the inner movable barrel 22, respectively. Connecting rings 211 are fixedly connected to the bottom of the three discharge pipes 210, and the connecting rings 211 are rotatably connected to the top of the annular plunger pump 212.

[0080] The annular plunger pump 212 is fixedly connected to a connecting injection pipe 213 at its outlet end. The annular plunger pump 212 introduces the material into the main mixing mechanism 30 through the connecting injection pipe 213. A feed hole is provided on the top side of the discharge port of the annular plunger pump 212. A one-way valve plate is provided inside the feed hole. A connecting hole is provided on the connecting ring 211 at the position of the discharge pipe 210. The diameter of the connecting hole and the feed hole are matched. A control valve is provided on the connecting ring 211 at the position of the discharge pipe 210 to control the closure of the top opening of the discharge pipe 210 of the three mixing chambers of the inner movable barrel 22.

[0081] During the mixing process, the discharge pipes 210 corresponding to the three mixing chambers rotate on top of the annular plunger pump 212 via connecting rings 211. Upon completion of mixing, the control valve of the discharge pipe 210 corresponding to the inlet of the annular plunger pump 212 is opened, and the annular plunger pump 212 is activated to draw material from the mixing chamber connected to it. As the annular plunger pump 212 advances, it pumps the material into the inner cavity of the main housing 31.

[0082] The three mixing chambers and the feed port of the annular plunger pump 212 are controlled in sequence, and the materials inside the three mixing chambers are pumped into the inner cavity of the main housing 31 by the annular plunger pump 212.

[0083] By setting the pumping part of the injection mechanism to an annular plunger pump 212, it is convenient to place the annular plunger pump 212 at the bottom of the housing 21, and the amount of material transferred by the annular plunger pump 212 in a single pumping is effectively increased.

[0084] Example 4

[0085] Please see Figure 6-10 The difference from the previous embodiment lies in the main mixing of the material. Specifically, the main mixing mechanism 30 includes a main housing 31, an inner eccentric shaft 32 is rotatably connected inside the main housing 31, a movable mesh plate 33 is movably connected to the side of the inner eccentric shaft 32, a top sealing plate 35 is fixedly connected to the top of the main housing 31, a main discharge port 37 is fixedly connected to the bottom of the outer side of the main housing 31, a connecting injection pipe 213 connects to the inner cavity of the main housing 31, and an annular plunger pump 212 pumps the material from the three mixing chambers of the inner movable barrel 22 into the inner cavity of the main housing 31 through the connecting injection pipe 213.

[0086] The inner eccentric shaft 32 has a movable groove, and the movable screen plate 33 is slidably connected in the movable groove. A return spring 34 is provided between the movable screen plate 33 and the inner eccentric shaft 32. The two ends of the return spring 34 are fixedly connected to the movable screen plate 33 and the inner eccentric shaft 32 respectively. The depth of the movable groove is adapted to the width of the movable screen plate 33. The inner eccentric shaft 32 fits against the inner wall of the main housing 31 near the main discharge port 37. The bottom and top of the movable screen plate 33 fit against the bottom of the main housing 31 and the bottom of the top sealing plate 35 respectively.

[0087] The inner eccentric shaft 32 has a drive wheel 36 that passes through the bottom of the main housing 31. A main drive assembly is provided outside the drive wheel 36. The main drive assembly is used to drive the inner eccentric shaft 32 to rotate through the drive wheel 36. The drive wheel 36 includes, but is not limited to, the driven pulley. The main drive assembly includes, but is not limited to, the driving pulley and the servo motor outside the driving pulley. The driving pulley and the driven pulley are connected by a belt.

[0088] The boring stirring process inside the main housing 31 is as follows: the servo motor drives the driven pulley to rotate through the active pulley and belt, and the driven pulley is set as the transmission wheel 36.

[0089] The transmission wheel 36 drives the inner eccentric shaft 32 to rotate. During the rotation, the inner eccentric shaft 32 drives the movable mesh plate 33 to rotate within the cavity of the main housing 31. Under the action of the return spring 34, the movable mesh plate 33 is always in contact with the inner cavity wall of the main housing 31. The cavity where the return spring 34 is located is formed by the bottom plate of the main housing 31, the top sealing plate 35, the two side walls of the movable groove of the inner eccentric shaft 32 and the side wall of the movable mesh plate 33, which prevents the colloid from entering the cavity where the return spring 34 is located, thereby ensuring that the main housing 31 can be stably rotated and mixed.

[0090] When the transmission wheel 36 drives the inner eccentric shaft 32 to rotate, the space between two adjacent movable mesh plates 33 changes from small to large and then from large to small. When the space between two adjacent movable mesh plates 33 decreases, the colloid in the gradually shrinking space is squeezed, causing the colloid to pass through the mesh of the movable mesh plate 33 into the adjacent area. The colloid inside the main shell 31 is segmented and squeezed through the mesh of the movable mesh plate 33. Compared with the traditional method of stirring using the stirring shaft 25, this method can effectively avoid the influence of the viscous properties of the colloid, thereby effectively improving the stirring effect of the colloid and increasing the mixing efficiency of the colloid.

[0091] Furthermore, the movable mesh plate 33 includes an outer plate 331 and an inner plate 332. The inner plate 332 is slidably connected inside the outer plate 331. A through mesh is provided between the outer plate 331 and the inner plate 332. When the through mesh of the outer plate 331 and the inner plate 332 overlap, the movable mesh plate 33 is a rectangular plate with a number of mesh holes. When the through mesh of the outer plate 331 and the inner plate 332 are completely misaligned, the movable mesh plate 33 is set as a closed rectangular plate.

[0092] An oil injection pipe 333 is provided on the outside of the outer plate 331. An oil injection chamber is provided between the outer plate 331 and the inner plate 332. The oil injection pipe 333 is connected to the oil injection chamber. The oil injection pipe 333 controls the position of the inner plate 332 inside the outer plate 331 by controlling the amount of oil injected into the oil injection chamber. The oil injection pipe 333 penetrates the axis of the inner eccentric shaft 32 and is connected to an external control oil pump.

[0093] When the material mixing inside the main shell 31 is completed, oil is injected into the oil injection chamber through the oil injection pipe 333. The oil pressure pushes the inner plate 332 to slide inside the outer plate 331, thereby controlling the misalignment of the through mesh of the inner plate 332 and the outer plate 331, achieving the effect of sealing the mesh of the movable mesh plate 33, making the movable mesh plate 33 a rectangular plate with closed mesh. At this time, the main discharge port 37 is opened. When the inner eccentric shaft 32 rotates, the movable mesh plate 33 with closed mesh shrinks in the area of ​​the movable mesh plate 33 with closed mesh, thereby squeezing the colloid out from the injection port, completing the preparation of medical cosmetic repair colloid.

[0094] The inner eccentric shaft 32 drives the movable mesh plate 33 to rotate, and the mesh openings of the movable mesh plate 33 are used to squeeze and mix the colloid inside the main shell 31. This avoids the influence of the high viscosity of the colloid on the stirring process, effectively improving the stirring effect and efficiency. At the same time, when the mesh openings of the movable mesh plate 33 are closed, the movable mesh plate 33, which facilitates the closing of the mesh openings, squeezes and discharges the colloid inside the main shell 31, effectively ensuring the discharge effect of the colloid and avoiding the generation of a large amount of colloid residue inside the main shell 31. This facilitates the complete discharge of the colloid and thus effectively ensures the performance of the device.

[0095] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
