Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical supplies, in particular to a portable hot compress and a preparation method and preparation equipment thereof. BACKGROUND

[0002] Sudden discomfort symptoms such as abdominal pain and diarrhea are common in daily life, especially for soldiers in the field. Such symptoms are difficult to relieve in time due to environmental restrictions and lack of medical resources. As a traditional and effective physical therapy method, hot compress can significantly alleviate the discomfort caused by symptoms such as abdominal pain and diarrhea by promoting local blood circulation and relieving muscle spasm, and has important medical value. In the field of medical device research, hot compress products are widely used in non-drug intervention therapy, and their portability, ease of use and stability of therapeutic effect are the core concerns in design and development. However, traditional hot compress medical devices, such as hot water bags or electric hot compress devices, are usually large in size and rely on external power or hot water sources, making it difficult to meet the needs of portability and immediacy in the field environment, especially in emergency medical scenarios, which cannot provide quick and effective support for soldiers.

[0003] In existing medical device technology, some portable hot compresses achieve self-heating function through chemical heating materials (such as iron powder oxidation reaction) and combine with ointment layers to enhance treatment effect. This type of hot compress is usually designed as a single-piece structure, directly attached to the affected area, with certain portability and medical applicability, widely used in home and outdoor scenarios. However, in the field medical environment, the existing portable hot compress still has the following technical limitations: first, the single-piece design is insufficient in terms of adhesion and fixation when covering a larger area of the affected area (such as the abdomen), especially in high-intensity exercise or dynamic environment, which is prone to slipping, affecting the treatment effect; second, the existing hot compress has a trigger mechanism for automatic heating after tearing open the package, lacking a controllable trigger method, users cannot flexibly choose the heating time according to the actual medical needs, limiting the intelligent and personalized application of the device; in addition, the existing products are mostly in flat or curled state when carried, occupying a large space, and after unfolding, it is difficult to quickly adjust to the shape suitable for the affected area, increasing the operation complexity in the field.

[0004] In view of the special medical needs of soldiers in the field environment, such as rapid deployment, portable storage and high efficiency of application, the medical device research field urgently needs to develop a new type of hot compress. The hot compress should optimize the adhesion and fixation on the basis of maintaining portability, provide a controllable heating trigger mechanism, and design a structure that adapts to dynamic environment, to meet the high standard requirements of efficient, convenient and reliable treatment in the field medical scene. This not only improves the health protection level of soldiers, but also provides a new research direction for the innovative design of portable medical devices. SUMMARY

DETAILED DESCRIPTION

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In this document, the term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0025] like Figures 1 to 6 As shown, the portable hot compress patch includes two hot compress components 3, two support plates 1, a flexible connector 2, and two trigger components 4. The hot compress components 3 are used to generate heat and apply it to the affected area through the ointment layer 305. The support plates 1 are used to fix and support the hot compress components 3. The flexible connector 2 is used to connect the two support plates 1 and realize the folding function. The trigger component 4 is used to trigger the heating layer 303 of the hot compress component 3 to generate heat.

[0026] Each hot compress assembly 3 includes a heating layer 303 and an ointment layer 305 .

[0027] Heating layer 303: The heating layer 303 is made of a material that can generate heat through a chemical reaction, specifically iron powder oxidation heating material. The thickness of the heating layer 303 is preferably 0.5 mm to 2 mm to ensure sufficient heat output and safety in use.

[0028] Ointment layer 305: The ointment layer 305 is disposed on the side of the heating layer 303 close to the affected area and contains medicinal ingredients. The thickness of the ointment layer 305 is preferably 0.2 mm to 1 mm to ensure that the medicine can effectively penetrate the affected area.

[0029] The two hot compress components 3 are respectively fixed to the inner surfaces of the two support plates 1, and the fixing method can be bonding.

[0030] The two support plates 1 are made of a lightweight yet rigid material, such as polypropylene (PP) or polycarbonate (PC), to provide structural support. Each support plate 1 is preferably 80 to 150 mm long, 50 to 100 mm wide, and 1 to 3 mm thick, to accommodate different affected areas (e.g., knees, waist, etc.). The inner surface of the support plate 1 is smooth, securing the hot compress assembly 3; the outer surface can be provided with a non-slip texture for easier handling and positioning.

[0031] The flexible connector 2 connects the two support plates 1, allowing them to fold relative to each other. The flexible connector 2 is preferably made of a flexible polymer material (such as silicone or thermoplastic polyurethane (TPU)). Its length is 20 to 50 mm, and its width is the same as that of the support plates 1. The thickness of the flexible connector 2 is preferably 0.5 to 2 mm to ensure both flexibility and durability. A crease may be provided in the middle of the flexible connector 2 to reduce folding resistance and ensure that the outer surface of the hot compress assembly 3 (i.e., the outer side of the heating layer 303) fits tightly together after the two support plates 1 are folded.

[0032] A trigger component 4 is provided on each support plate 1 for triggering the heating layer 303 of the corresponding hot compress component 3 to generate heat.

[0033] During actual use, the user places the hot compress patch on the affected area, allowing the ointment layer 305 to directly contact the skin and be located between the heating layer 303 and the affected area. The user operates the trigger component 4, activating the heating layer 303 to generate heat. The heat generated by the heating layer 303 is transferred to the affected area through the ointment layer 305, promoting the penetration of the medicinal ingredients in the ointment layer 305 and enhancing the therapeutic effect. When the patch needs to be stored or carried, the user folds the two support plates 1 using the flexible connector 2, so that the outer surfaces of the two hot compress components 3 (i.e., the outer sides of the heating layer 303) are in contact, thereby reducing the size and facilitating storage or carrying.

[0034] In this embodiment, the trigger component 4 is used to trigger the heating layer 303 of the hot compress component 3 to generate heat to achieve hot compress treatment, specifically including: The trigger assembly 4 includes a cover 401, a support arm 402, a limiting rod 403, a first spring 404, a base 405, an outer ring 406, a limiting ring 407, a column 411, a spike 412, a plurality of vent holes 413, an annular protrusion 414, a hole 417, and an inner ring 415. The structure and connection relationship of each component are as follows: Cover 401 forms the top structure of trigger assembly 4. Its smooth top facilitates user pressure. The bottom of cover 401 is securely connected to retaining ring 407 via adhesive or snap fasteners, while it is also connected to the top of outer ring 406 via threads or snap fasteners. Cover 401 is indirectly connected to retaining rod 403 via support arm 402, while outer ring 406 and retaining ring 407 are attached to support plate 1.

[0035] The support arm 402 is a component connecting the cover body 401 and the limiting rod 403. One end of the support arm 402 is connected to the inner side of the cover body 401, and the other end is connected to the top of the limiting rod 403.

[0036] The limiting rod 403 is a slender rod-shaped structure that passes through the inner ring 415 and is slidably connected to the inner ring 415 to play a guiding and limiting role. The two ends of the limiting rod 403 are fixedly connected to the bottom of the support arm 402 and the top of the base 405 respectively.

[0037] The first spring 404 is a compression spring that is sleeved on the limiting rod 403. One end of the first spring 404 abuts against the bottom of the inner ring 415, and the other end abuts against the top of the base 405. The first spring 404 provides elastic force to enable the inner ring 415 and the column 411 to return to their original position after movement.

[0038] The base 405 is the bottom structure of the trigger assembly 4 and is fixed to the outer surface of the support plate 1 by bonding or threading. The top of the base 405 is fixedly connected to the bottom of the limit rod 403 and serves as a support surface for the first spring 404.

[0039] The outer ring 406 is an annular structure and is arranged outside the limiting ring 407. The top of the outer ring 406 is connected to the bottom of the cover 401 through a thread, and the bottom is fixedly connected to the support plate 1 to protect the internal structure and enhance the overall stability.

[0040] The limiting ring 407 is an annular component, the top of which is fixedly connected to the cover 401, and the inner side is slidably connected to the outer surface of the column 411. The limiting ring 407 limits the movement direction of the column 411 to ensure that it slides along the axial direction.

[0041] The column 411 is a columnar structure that is slidably connected to the inner side of the limiting ring 407. The top of the column 411 is fixedly connected to the inner ring 415 through an annular protrusion 414, and the bottom is connected to the spike portion 412. A hole 417 is machined inside the column 411 to accommodate the inner ring 415 and the limiting rod 403.

[0042] The spike portion 412 is arranged below the column 411 and faces the heating layer 303. The spike portion 412 is conical or needle-shaped. When pressed, the spike portion 412 pierces the sealing structure of the heating layer 303, allowing oxygen to enter the heating layer 303 and trigger an oxidation heating reaction.

[0043] Multiple air holes 413 are evenly distributed throughout the column 411 and the spike portion 412. The air holes 413 allow air to enter the heating layer 303 through the column 411 and the spike portion 412 after being pressed, thereby controlling the rate of the heating reaction.

[0044] The annular protrusion 414 is a protrusion structure on the outer surface of the column 411 and is integrally formed with the column 411. The annular protrusion 414 is fixedly connected to the top of the inner ring 415. The outer side of the annular protrusion 414 is processed with grinding grooves, and the user can press or rotate the annular protrusion 414.

[0045] The hole 417 is a cavity inside the column 411, which is used to accommodate the inner ring 415, the limiting rod 403 and the first spring 404, ensuring the coordinated movement of these components during the pressing process.

[0046] The inner ring 415 is an annular component disposed in the hole 417 and fixedly connected to the inner wall of the hole 417. It is also slidably connected to the limit rod 403. The bottom of the inner ring 415 abuts against the top of the first spring 404, and the top is connected to the column 411 through the annular protrusion 414.

[0047] During actual use, the user presses the cover 401, and the cover 401 drives the limiting rod 403 to move downward through the support arm 402. The limiting rod 403 guides the inner ring 415 to slide along its axial direction, compressing the first spring 404, and at the same time pushing the column 411 to move downward. Under the constraint of the limiting ring 407, the column 411 slides axially, so that the spike portion 412 pierces the sealing structure of the heating layer 303. After puncture, air enters the heating layer 303 through multiple air holes 413, triggering an oxidation heating reaction and generating heat. The heat is transferred to the affected area through the ointment layer 305, promoting the penetration of the ointment ingredients and enhancing the therapeutic effect. After the pressing is completed, the elastic force of the first spring 404 resets the inner ring 415, the column 411 and the cover 401, and the spike portion 412 leaves the heating layer 303, but the air holes 413 maintain air circulation to ensure that the heating reaction continues. The base 405 and the outer ring 406 of the trigger assembly 4 are fixed to the support plate 1 to ensure the stability of the overall structure.

[0048] In this embodiment, the trigger assembly 4 further includes at least one first chute 408, at least one second chute 409, at least one piercing portion 416, and at least one water storage bag 410. The structure and connection relationship of each component are as follows: The first slide groove 408 is arranged along the circumference of the limiting ring 407 and is located on the inner side wall of the limiting ring 407. The end of the first slide groove 408 near the spike portion 412 is connected to one end of the second slide groove 409 to form a continuous slide groove path to guide the circumferential sliding of the piercing portion 416.

[0049] The second chute 409 is arranged along the axial direction of the limiting ring 407, located on the inner side wall of the limiting ring 407, and communicates with one end of the first chute 408. The second chute 409 guides the piercing portion 416 to slide axially, limiting the piercing portion 416 from contacting the water storage bag 410.

[0050] The piercing portion 416 is a slidable component fixedly connected to the outer surface of the column 411 and is capable of sliding within the first chute 408 and the second chute 409. When the piercing portion 416 slides axially within the second chute 409, the piercing portion 416 is positioned so that it cannot contact the water storage bladder 410. When the piercing portion 416 slides along the first chute 408 to the end away from the second chute 409, the piercing portion 416 is positioned so as to pierce the water storage bladder 410.

[0051] The water storage bag 410 is a bag-shaped structure for containing liquid and is fixedly connected to the bottom of the cover 401. The water storage bag 410 releases liquid after being punctured by the puncture portion 416. The liquid flows into the heating layer 303 and reacts with the material of the heating layer 303 to promote heating.

[0052] During actual use, the user presses the cover 401, causing the column 411 to slide axially, driving the piercing portion 416 to move axially within the second chute 409. At this point, the piercing portion 416 cannot contact the water reservoir 410 and does not puncture the water reservoir 410. This is the first mode, and the heating rate is slow. The user then rotates the cover 401, causing the column 411 to rotate, driving the piercing portion 416 from the second chute 409 into the first chute 408. It then slides along the first chute 408 to the end away from the second chute 409. At this point, the piercing portion 416 punctures the water reservoir 410, releasing the liquid. This puncture of the water reservoir 410, now in the second mode, accelerates the reaction of the heating layer 303 due to the release of liquid. The liquid flows into the heating layer 303 and reacts with the heating material, enhancing the heating effect. Heat is transferred to the affected area through the ointment layer 305, promoting the penetration of the ointment ingredients and improving the therapeutic effect.

[0053] In this embodiment, the hot compress assembly 3 is used to relieve muscle soreness, joint pain or promote blood circulation through heat therapy and medication. The structure, function and use of the hot compress assembly 3 are described in detail below.

[0054] The hot compress assembly 3 adopts a multi-layer structure, with the ointment layer 305, heating layer 303, first breathable protective layer 302, second breathable protective layer 306 and phase change material layer 304 sequentially wrapped in the non-woven fabric protective layer 301. The order of the layers from the side close to the affected area to the outside is: The second breathable protective layer 306: bamboo fiber non-woven fabric, gram weight 20-30g / m², air permeability 1800-2500g / m² / 24h, soft and skin-friendly, naturally antibacterial, and promotes ointment penetration.

[0067] Separate configuration: cavity one 3031: fill the exothermic mixture into the cavity wrapped with polypropylene microporous membrane on the outside, close to the phase change material layer 304. Cavity two 3032: fill sodium chloride into the cavity with polyethylene-polypropylene composite film (thickness 0.03-0.06 mm, tensile strength 10-15 MPa, puncture force ≤5 N) on the top, water-soluble polyvinyl alcohol (water-soluble polyvinyl alcohol) film (thickness 0.02-0.05 mm, dissolution time 5-10 seconds) on the side wall and bottom, close to the first breathable protective layer 302.

[0068] Cavity one 3031 and cavity two 3032 are separated by water-soluble polyvinyl alcohol film (thickness 0.02-0.05 mm).

[0069] Cavity 1 3031 and cavity 2 3032 are sealed as a whole in a non-breathable aluminum foil composite film bag (oxygen permeability <0.1 cm³ / m²·24h) to form a heating layer 303.

[0070] First mode (puncture air trigger): The trigger component 4 punctures the top of cavity 2 (polyethylene-polypropylene composite membrane), allowing oxygen to enter through the first breathable protective layer 302 and the single-sided breathable membrane of cavity 1, triggering a slow heat release (40-45°C, 5-6 hours). Second mode (puncture + water bladder trigger): The trigger component 4 punctures the top of cavity 2 3032 and opens the water storage bladder 410 (containing 4-6ml of water). Water is quickly injected, dissolving the water-soluble polyvinyl alcohol membrane and allowing sodium chloride solution to flow into cavity 1, triggering a rapid heat release (45-50°C, 4-5 hours).

[0071] Preparation of the first breathable protective layer 302: A polyester (PET) microporous membrane (thickness 0.02-0.05 mm, air permeability 1000-2000 g / m² / 24h) is used to form the first breathable protective layer 302. Preparation of the non-woven fabric protective layer 301: A polypropylene non-woven fabric (weight 35-45 g / m², thickness 0.2-0.4 mm) is used to form the non-woven fabric protective layer 301.

This formula balances the total weight (10g) and the amount of sesame oil (10ml), thus balancing efficacy and stability. This improves volatile oil retention by 10%, resulting in a uniform ointment suitable for general hot compresses.

[0080] Heating Layer 303: Cavity 1 (3031): Iron powder 55wt%, activated carbon microspheres 17wt%, vermiculite 10wt%, single-sided breathable film (polypropylene, air permeability 1500g / m² / 24h).

[0108] During actual use, the operator places the hot compress patch on the plane formed by the flap 501 and the pad 505 of the placement mechanism 5. The electric slide rail 7 drives the movable frame 8 to move along the straight groove 9, and the slide plate 506 slides under the guidance of the straight groove 9.

[0120] The connecting rod 611 is a transmission component, one end of which is fixedly connected with the lug 610, and the other end is fixedly connected with the scraper 612. The connecting rod 611 transmits the linear motion of the lug 610 to the scraper 612, and drives the scraper 612 to move.

[0121] The scraper 612 is a functional component with a hollow design and multiple openings 614 on the bottom. The scraper 612 is connected to the second rack 607 through a connecting rod 611 and a bump 610, and is connected to the glue injection tube 613. The scraper 612 is used to apply glue.

[0122] The glue injection tube 613 is a glue delivery component that is connected to the hollow structure of the scraper 612. The glue injection tube 613 delivers external glue to the scraper 612 and releases it to the surface of the hot compress through the opening 614.

[0123] A plurality of openings 614 are provided below the scraper 612, are evenly distributed, and are connected to the hollow structure of the scraper 612. The openings 614 are used to evenly apply the glue delivered by the glue injection tube 613 to the surface of the hot compress patch.

[0124] The rod 615 is a guide component, fixedly connected to the first outer frame 603, passing through the hole in the inner wall of the first rack 602, and slidingly connected to the first rack 602. The rod 615 guides the vertical sliding of the first rack 602.

[0125] The second spring 616 is an elastic component that is sleeved on the rod body 615. One end is fixedly connected to the first rack 602, and the other end is fixedly connected to the first outer frame 603. The second spring 616 provides elastic force to reset the first rack 602 after movement.

[0126] The resistance wire 617 is a heating component, which is arranged in or near the pressing surface of the hot pressing mechanism 6. The resistance wire 617 is heated by an electrical signal and is indirectly driven by the electric push rod 12 through the transmission system to perform hot pressing on the hot compress patch on the placement mechanism 5.

[0127] During actual use, the operator places the hot compress patch on the placement mechanism 5 and starts the device through the console 10. The electric push rod 12 drives the connecting plate 13 to move downward, driving the connecting block 601 and the first rack 602 to slide vertically along the rod body 615. When the resistance wire 617 is pressed onto the hot compress patch, the first rack 602 can no longer drive other structures to move downward. Instead, the first rack 602 moves downward by itself and squeezes the second spring 616. The second spring 616 is compressed and provides a restoring elastic force. The sliding of the first rack 602 drives the first gear 604 to rotate, which drives the second gear 606 to rotate through the connecting shaft 605. The second gear 606 drives the second rack 607 to slide horizontally along the limit bar 608. The second rack 607 drives the scraper 612 to move through the protrusion 610 and the connecting rod 611. The glue injection tube 613 transports the glue to the hollow structure of the scraper 612 and applies it to the surface of the hot compress patch through multiple openings 614. Simultaneously, the resistance wire 617 is heated under the control of the control console 10, hot-pressing the thermal compress into shape. The combined effects of heat and pressure ensure the quality of the thermal compress. After hot pressing is complete, the electric push rod 12 drives the connecting plate 13 to return to its original position. The second spring 616 resets the first rack 602, and the scraper 612 stops applying glue. The operator then removes the formed thermal compress.

[0128] It is worth noting that the shape of the resistance wire 617 is the same as the shape of the hot compress patch to be hot pressed, and the composition of the glue in the scraper 612 is: Acrylate copolymer (thermosensitive pressure-sensitive adhesive matrix): 55%. Provides low tack at room temperature (peel strength 0.5-1 N / cm) and high tack upon heating (peel strength 3-5 N / cm at 40-50°C). Low molecular weight polydimethylsiloxane (PDMS) (silicone adhesive): 25%. Provides fluidity at room temperature (viscosity 500-1000 cP), ensuring even application and leak-proof folding. Rosin ester (tackifier): 12%. Enhances the adhesive's adhesion to skin and heat pack materials. Citrate ester (plasticizer): 6%. Adjusts the adhesive's softness and prevents cracking during folding / unfolding. Nanosilica (filler): 1.5%. Optimizes rheological properties and enhances adhesive stability. BHT (antioxidant) (stabilizer): 0.5%. Prevents adhesive aging at high temperatures. The glue with this formula allows the user to peel the heat pack after applying and folding it. The glue's heat and pressure-sensitive properties ensure that its adhesion is primarily enhanced (peel strength 3-5 N / cm) upon heating (40-50°C, the heat pack's operating temperature) for adhesion to the skin. During the folding and tearing stages (typically performed at room temperature), the glue is still relatively unheated, maintaining a low viscosity and making it easier to tear.
