[0001] This invention relates to the field of wound care technology, specifically to a disinfection and nursing device for wound care. Background Art

[0002] Disinfection and care in wound treatment are crucial for preventing infection and promoting healing. With the development of medical technology and the upgrading of nursing needs, higher requirements have been placed on the precision, safety, adaptability and scenario compatibility of disinfection and care. In the clinical care of head wounds, the safety of the disinfection process and the patient's comfort have always been key issues that need to be addressed.

[0010] Furthermore, a number of first through holes are provided through one side of the air outlet plate.

[0011] Furthermore, the blocking component includes a fourth bracket and an electric push rod fixed inside the fourth bracket. The fourth bracket is fixedly connected to the housing.

[0012] Furthermore, the ionization device includes a vertical rod and an anode rod fixed to one side of the vertical rod. A first connecting wire is fixedly installed at one end of the anode rod, and one end of the first connecting wire passes through and connects to the vertical rod and the cylinder.

[0018] 3. Pulsed plasma can penetrate into the cavities of pressure injuries, destroying the cell membranes of anaerobic bacteria. Continuous airflow covers the hair gaps in the abrasion area, avoiding the risk of infection caused by foreign objects blocking the flow. The focused beam precisely acts on the suture gaps of superficial wounds, and the synergy between the main and auxiliary jets improves the disinfection coverage.

[0019] 4.

[0020] 5. The moving and lifting components enable precise three-dimensional positioning of the shell, and the driving component drives the agitator to automatically part the hair, reducing manual intervention and reliance on the experience of medical staff.

[0021] 6. The main jet of the deflector forms a large-area plasma cloud covering the wound, and the plasma diverted by the air intake is supplemented by close-range jetting through the air outlet of the actuating component, ensuring that each area is treated by both the main jet and the auxiliary jet, thereby improving the disinfection and nursing effect.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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.

[0025] To address the technical challenge of effectively penetrating and killing pathogens deep within head wound cavities caused by the impact of saline and disinfectant solutions, which result in significant pain for patients, such as... Figures 1-8 As shown, the following preferred technical solutions are provided: like Figures 1-2As shown, a disinfection and nursing device for wound treatment includes a nursing bed 1 with a headrest installed on it. The patient can lie on the nursing bed 1 and rest their head on the headrest to improve the patient's comfort during wound treatment. A movable component 2 is provided at the bottom of one end of the nursing bed 1, and a lifting component 3 is installed on one side of the movable component 2. A housing 4 is provided on the surface of the lifting component 3. The movable component 2 and the lifting component 3 respectively drive the housing 4 to move left and right and up and down, which can significantly improve the accuracy, convenience and patient comfort of head wound care. It can achieve precise positioning, reduce manual intervention, adapt to personalized needs and strengthen standardization, making head wound disinfection and care safer, more efficient and comfortable, and giving full play to the performance advantages of the disinfection device.

[0026] A cylinder 5 is connected through one side of the housing 4. A gas supply component 6 is installed inside the housing 4, which provides helium gas to support precise care of head wounds. An air outlet plate 7 is fixedly installed inside the cylinder 5. A blocking component 8 is installed on one side of the air outlet plate 7. The blocking component 8 can both misalign and connect the air outlet plate 7. When the gas supply component 6 outputs helium, the parameters of the helium output need to be adjusted according to different wound types, such as pressure injuries and superficial wounds. The misalignment or connection design of the blocking component 8 and the air outlet plate 7 can form a secondary regulation. When the two are fully connected, helium passes through without obstruction, which is combined with the large flow output of the gas supply component 6. When the two are partially misaligned, the flow cross section is reduced, and the helium flow rate is increased due to the throttling effect, forming a more directional airflow. When the two are completely misaligned, the helium delivery can be temporarily blocked to avoid ineffective consumption or accidental injection. In the pulse injection mode, the blocking component 8 and the air outlet plate 7 can be quickly switched to the connected state, so that the helium can instantly form a high-pressure pulse.

[0027] Furthermore, the blocking components 8 are all connected through the shell 4 and one side of the cylinder 5. The cylinder 5 is equipped with an ionization component 9. The gas delivery component 6 serves as the core power source for helium delivery. Through the misalignment and connection adjustment of the blocking components 8 and the air outlet plate 7, secondary precise flow control is achieved. Finally, the gas enters the ionization component 9 to complete the low-temperature plasma conversion. The blocking components 8 and the air outlet plate 7 are completely connected, and the gas delivery component 6 outputs a large flow of helium. Pressure injuries often have hidden cavities, such as the gap between the edge and normal tissue. The helium flow through the discharge gap of the ionization component 9 is excited to generate a diffusion-type low-temperature plasma cloud. The light blue plasma cloud has gas diffusion properties and can penetrate into the cavity. It destroys the cell membrane of anaerobic bacteria through active oxygen such as hydroxyl radicals, solving the problem of blind area infection that is difficult to reach by traditional disinfection methods. The low-energy particles released by the plasma cloud can regulate local cytokines in the wound, reduce redness and swelling inflammation of pressure injuries, and stimulate fibroblast proliferation and accelerate granulation tissue formation, which is suitable for the repair of chronic pressure injuries.

[0028] Its high-frequency electric field can enhance the permeability of wound tissue and promote exudate absorption. At the same time, it decomposes necrotic tissue debris through oxidation, reduces the accumulation of necrotic tissue, and reduces the difficulty of subsequent debridement and patient pain. Head abrasions are often accompanied by foreign objects such as mud, sand, and hair. These foreign objects are prone to forming bacterial biofilms. The active particles of the plasma cloud can penetrate the biofilm structure, destroy the adhesion between bacteria, and make the foreign objects easier to detach with the help of airflow. The rupture of capillaries in abrasion wounds can easily lead to bleeding. The plasma cloud can promote platelet aggregation and shorten the hemostasis time. Bacteria can easily hide in the gaps between sutures in superficial wounds. The fine flow pattern of the plasma cloud can be precisely applied to the area around the sutures, killing bacteria in the gaps in a non-contact manner. This avoids the pulling of sutures caused by traditional wiping disinfection and avoids physical contact with the fragile scalp tissue. Therefore, it not only solves the pain and blind spots of traditional saline and disinfectant disinfection, but also realizes personalized care for different wound types, significantly improving the efficiency, safety and patient comfort of head wound care.

[0029] Inside the cylinder 5, near the ionization element 9, a fan 10 is fixedly installed. A guide hood 20 is installed at one end of the cylinder 5. Helium gas forms a pulse jet through the misalignment or connection between the blocking element 8 and the air outlet plate 7. After ionization, it forms a high-concentration plasma pulse. At this time, the fan 10 synchronously envelops the plasma pulse with airflow, which can reduce the diffusion loss of particles during transmission. For the latent cavities of pressure injuries, the airflow of the fan 10 can guide the plasma pulse to impact along the cavity direction. For bacterial biofilms on the abrasion surface, the impact force of the pulsed plasma, combined with the continuous push of the airflow of the fan 10, can destroy the membrane structure and prolong the retention time of active particles on the wound surface, ensuring that the bacteria inside the biofilm are completely killed. After the helium gas is ionized by the pulse jet and then acts on the fan 10, it can not only retain the instantaneous impact force and high concentration characteristics of the pulse jet, but also significantly improve the depth, accuracy and safety of disinfection through the directional guidance, range expansion and safety buffering effect of the fan 10. With the cooperation of the fan 10, it forms a more suitable solution for the nursing needs of complex head wounds.

[0030] Furthermore, a driving component 30 is fixedly installed on the surface of the flow guide hood 20, and the driving component 30 is fixedly connected to one end of the cylinder 5. A toggle component 40 is installed on one side of the driving component 30. Two air inlets 50 are installed inside the flow guide hood 20, and both air inlets 50 are connected to the toggle component 40. An air outlet 60 is opened through one side of the toggle component 40. The driving component 30 drives the two toggle components 40 to mechanically move the hair on the head, ensuring that the hair around the incision is completely parted and falls to both sides. This active combing action solves the core problem of hair covering the wound in traditional disinfection. Fan 10 The ionized low-temperature plasma cloud is blown toward the incision through the guide hood 20. The air inlet 50 guides the plasma cloud into the actuating component 40, and then sprays it out at close range through the air outlet 60. The main path plasma cloud continuously covers the wound surface, and the air outlet 60 replenishes the spray as it moves, ensuring that each area is treated by both the main spray and the auxiliary spray. A high-definition vision sensor 70 is fixedly installed on the surface of the cylinder 5. The high-definition vision sensor 70 can identify pressure injuries, abrasions and superficial wounds on the head wound. The high-definition vision sensor 70 is electrically connected to the blocking component 8 through the controller.

[0031] like Figures 3-4 As shown, the movable component 2 includes an electric slide rail 21 and a slider 22 slidably connected to one side of the electric slide rail 21. The electric slide rail 21 can drive the slider 22 to move, which can adjust the position of the slider 22. The electric slide rail 21 is fixedly connected to the bottom of one end of the nursing bed 1. An L-shaped plate 23 is fixedly installed on one side of the slider 22. A first bracket 24 is fixedly installed on one end of the L-shaped plate 23. A first motor 25 is fixedly installed inside the first bracket 24. A threaded rod 26 is fixedly installed at the output end of the first motor 25, and the threaded rod 26 is rotatably connected to the L-shaped plate 23. The electric slide rail 21 can drive the slider 22 to move, and the movement of the slider 22 can drive the movement of the L-shaped plate 23, thereby adjusting the position of the L-shaped plate 23 and driving the flow guide 20 to move left and right. The first motor 25 can drive the threaded rod 26 to rotate, and the rotation of the threaded rod 26 can drive the lifting component 3 to adjust its position, which can drive the flow guide 20 to move back and forth, making it easier to adjust the position of the flow guide 20 and improving its applicability.

[0032] The lifting component 3 includes a frame plate 31 and a screw plate 32 fixed to one end of the frame plate 31. The screw plate 32 is threadedly connected to the threaded rod 26 and slidably connected to the L-shaped plate 23. A cylinder 33 is fixedly installed inside the frame plate 31. A connecting block 34 is slidably connected inside the frame plate 31. Vertical blocks for limiting are installed on both sides of the connecting block 34. The vertical blocks are slidably connected to the frame plate 31, which allows the connecting block 34 to slide stably inside the frame plate 31. The output end of the cylinder 33 is fixedly connected to the connecting block 34. A second bracket 35 is fixedly installed on one side of the connecting block 34. A second motor 36 is fixedly installed inside the second bracket 35. The housing 4 is rotatably connected to the connecting block 34 and is fixedly connected to the output end of the second motor 36. The connecting block 34 can be moved up and down by the cylinder 33, which can adjust the height of the guide shroud 20. The housing 4 can be rotated by the second motor 36, which is suitable for lateral head wounds and improves applicability.

[0033] like Figures 5-7 As shown, a partition 41 is fixedly installed inside the housing 4. The gas supply component 6 includes a third bracket 61 and a helium tank 62 fixed inside the third bracket 61. The third bracket 61 is fixedly connected to the housing 4, and the third bracket 61 stably fixes the helium tank 62 inside the housing 4 to prevent the helium tank 62 from shaking due to device movement or external force collision. One end of the helium tank 62 is connected to a connecting pipe 63, and the connecting pipe 63 passes through and connects to one side of the housing 4. A pad 64 is fixedly installed inside the housing 4, and an air pump 65 is fixed to one side of the pad 64. When the air pump 65 is working, it will generate high-frequency vibration. The pad 64 is usually made of rubber or silicone material to absorb vibration energy, prevent vibration from being transmitted to the housing 4 and causing other parts to loosen, and at the same time reduce vibration noise and improve environmental comfort. The connecting pipe 63 is connected to the air pump 65, and one end of the air pump 65 passes through and connects to one side of the partition 41. The helium tank 62 serves as the core of the gas source, storing high-pressure helium inside, and is fixed to the housing 4 by the third bracket 61. When the air pump 65 is started, the helium gas inside the helium tank 62 is transported to the inside of the cylinder 5 through the connecting pipe 63.

[0034] The air outlet plate 7 has several first through holes 71 through one side, which facilitates helium gas to pass through and enter the next stage. The blocking component 8 includes a fourth bracket 81 and an electric push rod 82 fixed inside the fourth bracket 81. The fourth bracket 81 is fixedly connected to the housing 4. The output end of the electric push rod 82 is connected through one side of the housing 4. A support rod 83 is fixedly installed at the output end of the electric push rod 82 and is connected through one side of the cylinder 5. A baffle 84 is fixedly installed at one end of the support rod 83 and is slidably connected to the air outlet plate 7. Several second through holes 85 corresponding to the first through holes 71 are through the surface of the baffle 84. T-shaped blocks 86 are fixedly installed on both sides of the baffle 84 and are slidably connected to the air outlet plate 7.

[0035] In the initial state, the baffle 84 is in a default semi-misaligned state. The first through hole 71 and the second through hole 85 partially overlap. The T-shaped block 86 is embedded in the groove of the air outlet plate 7 to ensure that the baffle 84 fits stably. When the high-definition vision sensor 70 identifies the wound type, such as pressure injury, abrasion or superficial wound, it sends an adjustment command to the electric push rod 82 through the controller (the controller is existing technology and is not shown in the figure). The fourth bracket 81 provides rigid support for the electric push rod 82 to avoid shaking during driving. Pressure injury treatment: pulsed high-pressure jet is required. The electric push rod 82 drives the support rod 83 to reciprocate at high frequency, causing the baffle 84 to slide on the surface of the air outlet plate 7. When the second through hole 85 is fully aligned with the first through hole 71, helium gas forms a high-pressure airflow through all the through holes. When the baffle 84 slides to the point where the through holes are completely misaligned, the airflow is temporarily blocked. The pulse jet is formed by the rapid switching between connection and misalignment, which is suitable for the deep disinfection needs of the cavities.

[0036] Abrasion treatment: Continuous airflow is required. The electric push rod 82 fixes the baffle 84 in the connected position, and the second through hole 85 is fully connected with the first through hole 71. The T-block 86 restricts the deviation of the baffle 84, ensuring that the second through hole 85 and the first through hole 71 are stably aligned. Helium is continuously output, taking into account both foreign object removal and gentle stimulation.

[0037] For superficial wound treatment: a focused beam is required. The electric push rod 82 drives the baffle 84 to a small-area connected state. The second through hole 85 and the first through hole 71 are in a semi-connected state. By reducing the flow cross-section, the helium flow rate is increased, which can be precisely applied to the area around the suture line and reduce the impact on healthy tissue. Therefore, the plasma action mode can be dynamically adapted according to the wound type.

[0038] The ionization device 9 includes a vertical rod 91 and an anode rod 92 fixed to one side of the vertical rod 91. A first connecting line 93 is fixedly installed at one end of the anode rod 92, and one end of the first connecting line 93 passes through and connects the vertical rod 91 and the cylinder 5. A high-frequency power supply 94 is fixedly installed on one side of the housing 4. The first connecting line 93 is electrically connected to the high-frequency power supply 94. An annular cathode plate 95 is fixedly installed on the inner wall of the cylinder 5 near the anode rod 92. A second connecting line 96 is fixedly installed on one side of the annular cathode plate 95, and the second connecting line 96 is electrically connected to the high-frequency power supply 94.

[0039] The plasma is generated through the discharge action of the anode rod 92 and the annular cathode plate 95, combined with the energy supply of the high-frequency power supply 94. The high-frequency power supply 94 supplies power to the anode rod 92 through the first connecting line 93 and to the annular cathode plate 95 through the second connecting line 96, forming a closed circuit. The first connecting line 93 passes through the vertical rod 91 and the cylinder 5 to ensure a stable connection with the anode rod 92. The second connecting line 96 directly connects the annular cathode plate 95 and the high-frequency power supply 94 to reduce energy transmission loss. The vertical rod 91 fixes the anode rod 92, keeping it at the axial position of the cylinder 5 and forming a uniform discharge gap with the annular cathode plate 95. Helium gas, after being adjusted by the baffle 84 and the air outlet plate 7, enters the interior of the cylinder 5 and flows along the inner side of the annular cathode plate 95, uniformly surrounding the anode rod 92. At this time, the helium gas fills the discharge gap under the action of the airflow, providing a stable gas source environment for plasma generation.

[0040] The high-frequency high-voltage electricity output by the high-frequency power supply 94 creates a strong electric field between the anode rod 92 and the annular cathode plate 95. Helium molecules are ionized under the action of the strong electric field, and electrons are released from helium atoms to form positively charged ions and free electrons. At the same time, active particles such as hydroxyl radicals are excited and generated. Due to the inert properties of helium and the precise control of the discharge gap, the plasma temperature can be stabilized at a low temperature plasma below 35°C, avoiding thermal damage to the head wound. The generated low-temperature plasma is ejected from the cylinder 5 outlet under the propulsion of the airflow and guided to the head wound through the guide hood 20. At the same time, part of the plasma enters the actuating component 40 through the air inlet 50 and acts on the wound surface between the hairs through the air outlet 60, forming a dual disinfection of main spray and auxiliary spray. This achieves efficient and low-temperature ionization of helium. The generated plasma has both high activity and safety, and is precisely adapted to the diverse disinfection needs of head wounds. While improving the sterilization effect, it maximizes the patient's comfort.

[0041] To address the technical problem of incomplete coverage during disinfection and nursing care, such as Figure 8 As shown, the following preferred technical solutions are provided: The driving component 30 includes a frame 301 and a third motor 302 fixed to one end of the frame 301. A bidirectional screw 303 is fixedly installed at the output end of the third motor 302, and the bidirectional screw 303 is rotatably connected to the frame 301. The third motor 302 drives the bidirectional screw 303 to rotate, and the rotation of the bidirectional screw 303 can drive the two actuating components 40 to move relative to each other. As the bidirectional screw 303 rotates, the two actuating components 40 move stably under the guidance of the frame 301. The actuating components 40 are inserted into the hair on the head. For areas with dense hair, the actuating components 40 slowly approach and push the hair to both sides to form an unobstructed channel, which facilitates the direct action of plasma on the wound surface.

[0042] The agitator 40 includes a movable plate 401 and a support plate 402 fixed to one side of the movable plate 401. The support plate 402 is threadedly connected to the bidirectional screw 303 and slidably connected to the frame 301. Several comb teeth 403 are fixedly installed on one side of the movable plate 401. The support plate 402 can play a connecting role and the hair is parted to both sides through the gaps between the comb teeth 403.

[0043] The air intake component 50 includes two horizontal pipes 501 and an air inlet 502 extending through the surface of the horizontal pipes 501. Both horizontal pipes 501 are connected to both sides of the flow guide 20. Telescopic hoses 503 are installed at both ends of the horizontal pipes 501 and are connected to the moving plate 401. When the low-temperature plasma generated by ionization enters the flow guide 20 through the cylinder 5, most of the plasma is sprayed toward the head wound through the main channel of the flow guide 20, and some of the plasma enters the moving plate 401 through the air inlet 502 on the surface of the horizontal pipes 501. The telescopic hose 503 is made of medical-grade silicone, which has good flexibility and sealing properties. It always maintains a connection with the moving plate 401 to avoid plasma leakage caused by movement. The plasma delivered by the telescopic hose 503 eventually enters the interior of the moving plate 401 and is ejected through the vent 60 on the surface of the moving plate 401. Because the moving plate 401 is precisely fitted to the hair around the wound, the vent 60 can spray plasma at close range into the gaps between hairs, wound edge folds and other areas, forming a three-dimensional coverage with the main jet of the guide hood 20.
