Description

Technical Field

[0001] This invention relates to the field of dressing technology, specifically to a wound dressing device. Background Technology

[0002] Currently, the application of medication to surgical wounds to promote healing and prevent infection often involves manually sprinkling the medication onto the wound before bandaging it. This method has the following drawbacks:

[0003] 1. Applying medication is mostly used in hospital procedures, but when nurses change dressings for patients in different wards at the same time, the manual labor intensity is high.

[0004] 2. If medical staff directly sprinkle the powder on the wound, too much powder may accumulate in one place. In this case, cotton swabs will be used to spread the excess powder evenly. Cotton swabs can cause pain when they come into contact with the wound and also increase the time spent on medical care.

[0005] 3. When used in low-temperature environments, existing devices cannot heat the medication, which can easily cause discomfort to the patient when the medication comes into contact with the wound.

[0006] For example, patent number CN210873667U, publication date June 30, 2020, discloses a disposable portable cervical powder sprayer, including a reservoir. The reservoir has a switch valve on its front outer surface, an airbag on one side of its outer surface, and a dispensing tube on the other side of its outer surface. One end of the dispensing tube has a dispensing hole. It also sprays the medicine evenly onto the cervical lesions or postoperative cervical wounds. However, its structure is simple, the spraying effect is poor, and it cannot mix or heat the medicine.

[0007] For example, patent number CN210384540U, published on 2020-04-24, discloses a syringe, including a syringe barrel, a connector at the top of the syringe barrel, a syringe needle on the connector, a syringe plunger inside the syringe barrel that is pushed from one end of the syringe barrel to the other end, and a medicine cartridge on the syringe barrel. The medicine cartridge is there so that when medicine powder or other liquid medicine is needed for wound care, the medicine powder can be sprinkled out to realize the multi-functional use of the injection.

[0008] Therefore, it is evident that current medical devices lack wound dressing devices to replace manual application of medication. To address this deficiency, we propose a wound dressing device. Summary of the Invention

[0009] The purpose of this invention is to provide a wound dressing device to solve the problems of how to replace manual application of medicine to patients' wounds and how to heat the medicine when used in low-temperature environments, thereby solving the problem of discomfort caused to patients when the medicine comes into contact with the wound.

[0010] To achieve the above objectives, the present invention provides the following technical solution: a wound dressing device, comprising a box body, wherein the top of the box body is provided with an inlet and the bottom with an outlet, the box body is provided with a mixing chamber for mixing one or more drugs, below the mixing chamber is a uniform dispensing chamber for distributing the mixed one or more drugs, and below the uniform dispensing chamber is a heating chamber for heating the dispensed one or more drugs, the outlet end of the heating chamber is located above the outlet, thereby satisfying the requirement that different drugs enter from the inlet at the top of the box body, are mixed inside the box body and discharged from the outlet. In use, the outlet is positioned above the wound and moved at a uniform speed.

[0011] In a preferred embodiment of the present invention: the mixing chamber includes a partition installed on the inner wall of the box for receiving the drug fed into the inlet. The top surface of the partition is arc-shaped. A first rotating shaft is installed above the partition. A stirring component is connected to the outer wall of the first rotating shaft. The end of the stirring component away from the first rotating shaft can slide against the arc-shaped surface of the partition. A valve is provided at the bottom of the partition for controlling the mixing time of the drug in the mixing chamber. A drive unit is provided on the box to drive the first rotating shaft to rotate. The first rotating shaft can drive the stirring component to maintain contact and slide against the arc-shaped surface of the partition while rotating, thereby achieving the effect of turning the drug on the arc-shaped surface.

[0012] In a preferred embodiment of the present invention: the stirring component includes multiple fixed shafts circumferentially distributed around the center of a first rotating shaft. The multiple fixed shafts are fixedly connected to the outer wall of the first rotating shaft. A rotating plate is connected to the fixed shaft via a torsion spring. The initial limit position of the rotating plate is parallel to the axis of the first rotating shaft. A lever is connected to the side wall of the box to rotate the rotating plate around the fixed shaft. The end face of the rotating plate contacts the lever on the side wall of the box, causing the rotating plate to rotate around the fixed shaft and compress the torsion spring. The powder on the rotating plate falls off and is turned over. As the first rotating shaft rotates continuously, the multiple sets of rotating plates continuously turn over the powder on the top of the partition.

[0013] In a preferred embodiment of the present invention: the valve includes a plurality of first leakage channels arranged at equal intervals on the partition plate, and a slot through which the plurality of first leakage channels are formed on the partition plate. An insert plate for sealing the first leakage channels is inserted into the slot. The insert plate has a second leakage channel corresponding to the first leakage channels, and a driving part is provided in the box body to drive the insert plate to slide in the slot. By driving the insert plate to slide, the second leakage channel of the insert plate can selectively maintain communication with the first leakage channel. When the first leakage channel and the second leakage channel are in communication, the drug falls from the first leakage channel and the second leakage channel into the uniform feeding chamber. At the same time, the rotating plate above the partition plate moves to accelerate the discharge of the drug.

[0014] As a preferred embodiment of the present invention: the driving part for the insert plate to slide in the slot includes an electric telescopic rod installed on the inner wall of the box, a support rod is fixedly connected to the lower end face of the insert plate, the output end of the electric telescopic rod is fixed to the support rod, and a sliding groove for the support rod to slide is opened at the lower end of the partition plate. The insert plate is moved by the extension of the electric telescopic rod, so that the first leakage groove and the second leakage groove remain in communication.

[0015] As a preferred embodiment of the present invention: the uniform feeding chamber includes a U-shaped cover fixedly connected to the bottom of the partition. A propeller is rotatably arranged inside the U-shaped cover. The edge of the propeller slides against the arc-shaped inner wall of the U-shaped cover. Multiple sets of third discharge troughs are opened at the bottom of the U-shaped cover. There are interval areas for storing drugs between the multiple sets of third discharge troughs. The box body is provided with a drive unit for driving the propeller to rotate. When the propeller rotates selectively in both directions, it evenly distributes the drugs in the U-shaped cover into the multiple third discharge troughs and conveys them downward into the heating chamber. There are interval areas between the multiple sets of third discharge troughs. When the drugs fall into the interval areas, they remain in the U-shaped cover. Through the rotation of the propeller, the drugs in the interval areas are conveyed to the adjacent third discharge troughs, thereby achieving the effect of uniform feeding.

[0016] As a preferred embodiment of the present invention: the heating chamber includes two sets of symmetrically arranged heating chambers, the third discharge trough is located at the opening of the heating chamber, the bottom of the heating chamber is provided with a heating channel, the heating chamber and the heating channel are connected and a heat source is provided inside, the heating chamber is provided with a connecting component, the connecting component includes a second rotating shaft and multiple baffles fixedly connected to the second rotating shaft, a temporary storage cavity with a top opening is formed between two adjacent baffles and the second rotating shaft, the temporary storage cavity is used to hold the medicine falling from the third discharge trough, the box body is provided with a driving part for driving the second rotating shaft to rotate, the temporary storage cavity with a trapezoidal cross section is formed between two adjacent baffles and the second rotating shaft, by rotating the second rotating shaft, the temporary storage cavity gradually opens downward, thereby discharging the medicine inside from the heating channel, the heating chamber and the heating channel are connected inside, a heat source can be added inside, so that heat is generated inside to heat the medicine, and the function of setting the second rotating shaft and multiple baffles is to keep the medicine in the temporary storage cavity for a period of time for heating.

[0017] In a preferred embodiment of the present invention: a third rotating shaft and a driving unit for driving the third rotating shaft to rotate are installed between the two heating channels. At least one fixed block is installed on the third rotating shaft. A clamp is connected to the fixed block through a telescopic rod. A spring with its two ends abutting against the fixed block and the clamp is sleeved on the telescopic rod. Multiple semi-cylinders are installed on the inner wall of the heating channel, and grooves are formed between the multiple semi-cylinders. The clamp moves across the multiple grooves and generates vibration. As the third rotating shaft rotates, it drives the fixed block to rotate, thereby further causing the clamp to move across the grooves between the multiple semi-cylinders, thereby causing the heating chamber to vibrate, and further causing the adapter to vibrate. Therefore, the drug particles located in the trapezoidal temporary storage cavity are automatically flipped, thereby ensuring uniform heating.

[0018] As a preferred embodiment of the present invention: the cross-section of the temporary storage cavity is trapezoidal. The trapezoidal storage cavity is more convenient for receiving materials at the top, and the central vibration amplitude is large when the short side of the trapezoid vibrates, which can effectively tumble the drug in the trapezoidal cavity from the center upwards, ensuring the uniformity of heating.

[0019] In a preferred embodiment of the present invention: a box body is installed on the side wall of the box body; wherein, the driving part for driving the first rotating shaft to rotate includes a first turntable rotatably connected to the outer wall of the box body, and one end of the first rotating shaft passes through the box body and is fixed to the first turntable; the driving part for driving the second rotating shaft to rotate includes a second turntable rotating on the outer wall of the box body, and one end of the second rotating shaft passes through the box body and is fixed to the second turntable, and meshing gears are fixed on both second rotating shafts; the driving part for driving the propeller to rotate and the driving part for driving the third rotating shaft to rotate both include a synchronous transmission component, which is used to keep the propeller and the third rotating shaft rotating synchronously with the first rotating shaft.

[0020] As a preferred embodiment of the present invention, the synchronous transmission component adopts a sprocket mechanism or a pulley mechanism.

[0021] As a preferred embodiment of the present invention: a drive source is installed on the side wall of the box, and the drive source drives the rotating parts in the mixing chamber and / or uniform feeding chamber and / or heating chamber to mix and feed materials. The drive source is manual or electric.

[0022] In a preferred embodiment of the present invention: the width of the inlet at the top of the box is greater than the width of the outlet at the bottom of the box; a cover is rotatably mounted on the inlet; a filter screen is provided inside the inlet; the box includes a first edge sidewall; a second edge sidewall fixedly connected to the upper end of the first edge sidewall, the second edge sidewall extending upward to form the inlet; and an arc-shaped plate connected to the bottom of the first edge sidewall, the arc-shaped plate moving inward and fixedly connected to a third edge sidewall, the third edge sidewall extending downward to form the outlet.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention adds a mixing chamber for mixing one or more materials into a handheld box, and sets a uniform feeding chamber at the bottom of the mixing chamber, and seals two heating chambers on both sides below the uniform feeding chamber. Thus, one or more drugs only need to be put into the feeding port, and the heated drugs can be evenly covered on the wound through processing inside the box. The present invention has the advantages of convenient use and easy portability because it installs multiple components in a compact combination in the box to heat the drugs and apply them evenly.

[0024] This invention adds a third rotating shaft that rotates synchronously with the first rotating shaft between the two heating channels. The clamp on the third rotating shaft engages with the semi-cylinders inside the two heating channels, causing the entire heating chamber to vibrate. This, in turn, causes the temporary storage cavity with a top opening formed by two adjacent baffles on the second rotating shaft to vibrate. The drug in the temporary storage cavity also vibrates, and the drug particles tumble irregularly inside, improving the drug heating efficiency.

[0025] This invention can be used in low-temperature environments and can mix different types of drugs. For example, it can fully mix honey and Chinese medicine granules used in traditional Chinese medicine poultices. Due to the fluidity of honey, the honey and Chinese medicine granules are fully mixed in the mixing chamber of this device. The Chinese medicine granules are then preheated in the heating chamber, causing the medicinal components to overflow and mix with the honey. After mixing, the medicine can be adjusted. When applied to the human body, the medicine can stay moist for up to a week, and the medicinal effect lasts for a long time without irritating the skin. This solves the problem of traditional poultices drying out quickly and not being effective. Attached Figure Description

[0036] The technical aspects of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0037] This invention relates to a wound dressing device, which includes a box body 1. The box body 1 has an inlet 11 at the upper end and an outlet 16 at the bottom. Different medicines enter from the inlet 11 at the top of the box body 1, are mixed and processed inside the box body 1, and are discharged from the outlet 16. When in use, the outlet 16 is positioned above the wound and moved at a uniform speed.

[0038] Please see Figures 1-5 The box body 1 is hollow. The width of the top inlet 11 is greater than the width of the bottom outlet 16 of the box body 1. The inlet 11 is rotatably fitted with a box cover 12. The inlet 11 is equipped with a filter screen 14. When the box cover 12 is opened, one or more drugs are put into the inlet 11 and enter the box body 1 through the filter screen 14.

[0039] It should be pointed out that, as Figure 8 As shown, the width of the inlet 11 at the top of the box body 1 is greater than the width of the outlet 16 at the bottom of the box body 1. It can be understood that the upper end of the first edge sidewall 111 of the box body 1 is fixedly connected to the second edge sidewall 112, the second edge sidewall 112 forms the inlet 11, and the top is provided with a box cover (12). The lower end of the first edge sidewall 111 is connected to the third edge sidewall 114 through the arc plate 113, the third edge sidewall 114 forms the outlet 16, and the presence of the arc plate 113 serves to gather the medicine towards the third edge sidewall 114 and discharge it from the outlet 16.

[0040] The box 1 contains a mixing chamber 3 for mixing one or more drugs, such as... Figure 2 As shown, below the mixing chamber 3 is a uniform feeding chamber 4 for distributing one or more mixed drugs, and below the uniform feeding chamber 4 is a heating chamber 5 for heating one or more drugs after feeding. After heating, the drugs are discharged from the outlet 16 at the bottom of the box 1. Specifically, the drugs are filtered through the filter screen 14 in the inlet 11 and then enter the mixing chamber 3 for mixing. Through the mixing of drugs, multiple drugs are evenly distributed on the patient's wound. The presence of the uniform feeding chamber 4 ensures that the drugs are evenly fed from the outlet 16 at the bottom of the box 1, avoiding the drugs being discharged from only one position in the outlet 16. The heating chamber 5 is optional. When heating is not required, the heating component is turned off, so it can be used as a transfer device. The internal structure of the box 1 will be described in detail below.

[0041] Please seeFigures 2-7 The mixing chamber 3 includes a partition 15 installed on the inner wall of the box 1 and located below the filter screen 14. The top surface of the partition 15 is arc-shaped, and the bottom surface of the partition 15 can be either flat or arc-shaped. A first rotating shaft 31 is installed above the partition 15. The first rotating shaft 31 is located between the filter screen 14 and the partition 15, and the first rotating shaft 31 is located above the center of the partition 15. A stirring component is connected to the outer wall of the first rotating shaft 31. The end of the stirring component away from the first rotating shaft 31 can slide against the arc-shaped surface of the partition 15. Thus, when the medicine falls from the filter screen 14 onto the arc-shaped surface of the partition 15, the rotation of the first rotating shaft 31 drives the stirring component to stir one or more medicines on the partition 15 to make them fully mixed. The function of the first rotating shaft 31 being located above the center of the partition 15 is to ensure that the stirring component always slides against the arc-shaped surface of the partition 15 when rotating and contacting it, thereby achieving the effect of turning the medicine on the arc-shaped surface.

[0042] The specific stirring component includes multiple fixed shafts 32 arranged circumferentially around the center of the first rotating shaft 31. These fixed shafts 32 are fixedly connected to the outer wall of the first rotating shaft 31. Rotating plates 33 are connected to the fixed shafts 32 via torsion springs. The initial limit position of the rotating plates 33 is parallel to the axis of the first rotating shaft 31. This can be understood as the end face of the rotating plates 33 being parallel to the axis of the first rotating shaft 31 in its natural state. Without external force, it can flip the powder on the arc-shaped surface of the partition 15 from the bottom to the upper edge. As the first rotating shaft 31 continues to rotate, the end face of the rotating plate 33 contacts the lever 34 set on the side wall of the box 1, causing the rotating plate 33 to rotate around the fixed shaft 32 and compress the torsion spring. The powder on the rotating plate 33 falls and is turned over. As the first rotating shaft 31 continues to rotate, multiple sets of rotating plates 33 continuously turn over the powder on the top of the partition 15. Multiple fixed shafts 32 are perpendicular to the axis of the first rotating shaft 31. The advantage of this setting is that it can improve the smoothness of the contact between the rotating plate 33 and the lever 34.

[0043] like Figure 3 , 4As shown in Figures 5 and 7, after the drugs are mixed in the mixing chamber 3, a valve is installed at the bottom of the mixing chamber 3 to facilitate the entry of the drugs in the mixing chamber 3 into the uniform feeding chamber 4. The valve controls the mixing time of the drugs in the mixing chamber 3, thereby improving the uniformity of mixing. Specifically, multiple first discharge grooves 35 are provided on the partition plate 15, and the multiple first discharge grooves 35 are arranged at equal intervals. A slot 36 is provided at one end of the partition plate 15, which passes through the multiple first discharge grooves 35. A plate 37 is inserted into the slot 36 to block the first discharge grooves 35. In order to ensure the uniformity of mixing, the first discharge grooves 35 are sealed. The first leakage trough 35 serves as a leakage channel. Therefore, a second leakage trough 371 corresponding to the first leakage trough 35 is provided on the insert plate 37. A driving part is provided in the box body 1 to drive the insert plate 37 to slide in the slot 36. By driving the insert plate 37 to slide, the second leakage trough 371 of the insert plate 37 can selectively maintain communication with the first leakage trough 35. When the first leakage trough 35 and the second leakage trough 371 are in communication, the medicine falls from the first leakage trough 35 and the second leakage trough 371 into the uniform feeding chamber 4. At the same time, the rotating plate 33 above the partition plate 15 moves to accelerate the discharge of the medicine.

[0044] like Figure 3 and Figure 7 As shown, the drive unit that drives the insert plate 37 to slide in the slot 36 is preferably an electric telescopic rod 38 installed on the inner wall of the box body 1. A support rod 39 is fixedly connected to the lower end face of the insert plate 37. The output end of the electric telescopic rod 38 is fixed to the support rod 39. A sliding groove for the support rod 39 to slide is opened at the lower end of the partition plate 15.

[0045] Please see Figures 2-7 This embodiment discloses a specific implementation of the uniform feeding chamber 4, which includes a U-shaped cover 41 fixedly connected to the bottom of the partition 15. A propeller 42 is rotatably installed inside the U-shaped cover. The edge of the propeller 42 slides against the arc-shaped inner wall of the U-shaped cover 41, so that the medicine in the U-shaped cover 41 can be moved and dropped into multiple sets of third discharge troughs 43 opened at the bottom of the U-shaped cover 41. Thus, when the propeller 42 rotates selectively in both directions, the medicine in the U-shaped cover 41 is evenly distributed in multiple third discharge troughs 43 and conveyed downward into the heating chamber 5. There are interval areas between the multiple sets of third discharge troughs 43. When the medicine falls into the interval area, it remains in the U-shaped cover 41. Through the rotation of the propeller 42, the medicine in the interval area is conveyed to the adjacent third discharge trough 43, so as to achieve the effect of uniform feeding.

[0046] Please see Figures 5-6This embodiment discloses a specific implementation of the heating chamber 5, which includes two symmetrically arranged heating chambers 51. Each heating chamber 51 has a heating channel 53 at its bottom and a connecting component 52 inside. The connecting component 52 includes a second rotating shaft and multiple baffles fixedly connected to the second rotating shaft. A temporary storage cavity with a trapezoidal cross-section is formed between two adjacent baffles and the second rotating shaft. Rotation of the second rotating shaft causes the temporary storage cavity to gradually open downwards, allowing the internal drug to be discharged from the heating channel 53. The heating chambers 51 and the heating channel 53 are internally connected, allowing for the addition of a heat source to generate heat for heating the drug. The second rotating shaft and multiple baffles are designed to keep the drug in the temporary storage cavity for a period of time before heating. To ensure effective and uniform heating of the drug in the storage cavity, a third rotating shaft 6 is installed between the two heating channels 53, and one or more fixing blocks 61 are installed on the third rotating shaft 6. The fixing blocks 61 are used to support the clamping head 62. Figure 6 As shown, multiple semi-cylinders 54 are installed on the inner wall of the heating channel 53, forming grooves between them. A clamp 62 is used to engage in the grooves. The fixing block 61 is connected to the clamp 62 via a telescopic rod 63. A spring 64 is sleeved on the telescopic rod 63, with its two ends abutting against the fixing block 61 and the clamp 62 respectively, providing support for the clamp 62. As the third rotating shaft 6 rotates, it drives the fixing block 61 to rotate, thereby causing the clamp 62 to move across the grooves between the multiple semi-cylinders 54, causing the heating chamber 51 to vibrate, which in turn causes the adapter 52 to vibrate. Therefore, the drug particles in the trapezoidal temporary storage cavity are automatically flipped, ensuring uniform heating. The trapezoidal storage cavity is more convenient for receiving materials at the top, and the central vibration amplitude is large when the short side of the trapezoid vibrates, which can effectively tumble the drug in the trapezoidal cavity from the center upwards, ensuring uniform heating.

[0047] It should be noted that, in order to disperse and heat the drug in this embodiment, the above-mentioned multiple sets of third discharge troughs 43 are set as two in each set and arranged symmetrically. The opening end of each heating chamber 51 is placed in the multiple third discharge troughs 43. Therefore, when the propeller 42 rotates, the drug in the interval area falls from the two third discharge troughs 43 in each set into the corresponding heating chamber 51, and is heated by receiving the drug through the temporary storage cavity formed between the multiple baffles on the adapter 52.

[0048] It should be noted that, in this invention, a housing 2 carrying a drive source is installed on the side wall of the housing 1. The housing 2 contains a drive source for driving the first rotating shaft 31, the second rotating shaft, the propeller 42, and the third rotating shaft 6 to rotate, such as... Figure 9As shown, this embodiment discloses a manually driven method, which includes a first turntable 21 and a second turntable 23 installed outside the housing 2. One end of the first rotating shaft 31 passes through the housing 2 and is fixed to the first turntable 21. The second rotating shaft of the adapter 52 extends through the housing 2 to the outside and is fixed to the second turntable 23. Since the second rotating shaft is symmetrically arranged, meshing gears (231) are fixed on both second rotating shafts. The advantage of this arrangement is that the mixing heating and spreading can be operated separately, and the first rotating shaft 31, the propeller 42 and the third rotating shaft 6 are connected by a synchronous transmission component 22. The synchronous transmission component 22 can be a sprocket mechanism or a pulley mechanism, so that after rotating the first turntable 21, the first rotating shaft 31, the propeller 42 and the third rotating shaft 6 rotate synchronously. If a sprocket mechanism is used, sprockets are installed on the first rotating shaft 31, the propeller 42 and the third rotating shaft 6 respectively, and chains are connected between multiple sprockets to achieve synchronous rotation. The synchronous transmission mechanism 22 and the gears (231) can be hidden inside the housing 2.

[0049] Alternatively, the driving source can be achieved by using a combination of a drive motor and a reducer. An internal controller can be set up to control the drive motor to realize the operation of the entire device. Since electric drive is a common method in this field, it will not be elaborated on here.

[0050] In use, the user holds the handheld part 13, which may be equipped with a control switch or other components to control the start and stop of the device. The medicine is then filtered through the filter screen 14 in the feed inlet 11 and enters the mixing chamber 3 for mixing. Specifically, the first rotating shaft 31 is rotated electrically or manually. As the first rotating shaft 31 continues to rotate, the end face of the rotating plate 33 contacts the lever 34 located on the side wall of the housing 1, causing the rotating plate 33 to rotate around the fixed shaft 32 and compress the torsion spring. The powder on the rotating plate 33 then falls off, achieving a flipping effect. As the first rotating shaft 31 rotates continuously, multiple rotating plates 33 continuously tumble the powder on top of the partition 15. After tumbling for a period of time, the electric telescopic rod 38 pushes the support rod 39 to move, thereby driving the insert plate 37 to slide within the slot 36. This allows the second discharge trough 371 of the insert plate 37 to selectively maintain communication with the first discharge trough 35. When the first discharge trough 35 and the second discharge trough 371 are in communication, the medicine falls from the first discharge trough 35 and the second discharge trough 371 into the uniform feeding chamber 4. At the same time, the rotating plate above the partition 15... The movement of the propeller 42 accelerates the discharge of the drug, which enters the U-shaped shroud 41. The propeller 42 selectively rotates in both directions, evenly distributing the drug within the U-shaped shroud 41 into multiple third discharge troughs 43 and conveying it downwards into the heating chamber 5. The rotation of the second shaft causes the storage chamber to gradually open downwards, discharging the drug from the heating channel 53. The heating chamber 51 and the heating channel 53 are interconnected, allowing for the addition of a heat source to generate heat and heat the drug. The second shaft and multiple baffles are designed to maintain... The drug is placed in the temporary storage chamber for a period of time for heating. In order to ensure that the drug in the storage chamber is heated effectively and evenly, the rotation of the third rotating shaft 6 drives the fixed block 61 to rotate, thereby causing the clamp 62 to move in the groove between multiple semi-cylinders 54, which in turn causes the heating chamber 51 to vibrate, and further causes the adapter 52 to vibrate. As a result, the drug particles in the temporary storage chamber with a trapezoidal cross section are automatically flipped, thereby ensuring uniform heating. After heating, the drug is evenly spread on the patient's wound from the discharge port 16.

[0051] This invention adds a mixing chamber 3 for mixing one or more materials inside a handheld box 1, and a uniform feeding chamber 4 at the bottom of the mixing chamber 3. Two heating chambers 5 are sealed and connected to both sides below the uniform feeding chamber 4. Thus, one or more drugs only need to be put into the inlet 11, and the heated drugs can be evenly applied to the wound through the internal processing of the box 1. This invention has the advantages of being convenient to use and easy to carry because it combines multiple components in a compact structure and installs them in the box 1 to heat the drugs and apply them evenly.

[0052] The present invention adds a third rotating shaft 6 between the two heating channels 53, which rotates synchronously with the first rotating shaft 31. The clamp 62 on the third rotating shaft 6 cooperates with the semi-cylinder 54 inside the two heating channels 53 to make the entire heating chamber 5 vibrate. This causes the temporary storage cavity with a top opening formed by two adjacent baffles on the second rotating shaft to vibrate. The drug in the temporary storage cavity also vibrates, and the drug particles tumble irregularly inside, improving the drug heating efficiency.

[0053] For those skilled in the art, this wound dressing device is not limited to the medical field. It can also be used for applications such as mixing Chinese herbal granules and honey into a paste. For example, the honey and Chinese herbal granules used in traditional Chinese medicine dressings are thoroughly mixed. Due to the fluidity of honey, the honey and Chinese herbal granules are fully mixed in the mixing chamber 3 of this device. The Chinese herbal granules are then preheated in the heating chamber 5, causing the medicinal components to overflow and mix with the honey. After mixing, the medicine is adjusted. When applied to the human body, the medicine can stay on for up to a week, and the medicinal effect lasts for a long time without irritating the skin. This solves the problem of traditional dressings drying out quickly and not being effective. It should be noted that the heat source of the heating chamber 3 in this solution may include a heating module for heating the interior of the heating chamber 3, and an adjustment module for adjusting the heating temperature of the heating module to meet the temperature requirements for different drug ratios.
