Description

Technical Field

[0001] This invention relates to the field of wound cleaning, specifically to an ultrasonic atomizing wound cleaning device. Background Technology

[0002] Epidermal abrasions are the most common superficial soft tissue injuries in daily life and clinical practice. They are mostly caused by everyday bumps, sports impacts, and scrapes from objects. The injury only affects the epidermal layer of the skin and often manifests as a superficial wound with a small amount of bleeding and foreign objects such as mud, dust, and clothing fibers adhering to the surface. If the wound is not cleaned in time or thoroughly, it is very easy to cause wound infection, delayed healing, and even leave scars, pigmentation, and other problems, which seriously affect the patient's skin appearance and healing experience.

[0003] During the operation of specific embodiments, the inventors discovered the following defects: The mechanical friction of cotton swabs can easily damage newly formed cells repairing the wound, exacerbating the patient's pain. Furthermore, cotton swab fibers can easily remain on the wound, creating foreign body irritation and hindering wound healing. At the same time, cotton swabs cannot reach deep into the tiny gaps of epidermal abrasions, making it difficult to achieve thorough cleaning. Especially for wounds with biofilms, the biofilm removal rate of conventional cotton swabs is less than 22%, which cannot effectively reduce the bacterial load and easily leads to infection recurrence.

[0004] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Summary of the Invention

[0005] 1. The technical problem that the invention aims to solve: This invention provides an ultrasonic atomization wound cleaning device to solve the technical problems existing in the background art.

[0006] 2. Technical Solution: To achieve the above objectives, the technical solution provided by the present invention is as follows: an ultrasonic atomizing wound cleaning device, comprising a sealing structure, disinfectant diversion structures provided on both sides of the top of the sealing structure, ventilation structures provided on both sides of the inner wall of the sealing structure, an atomizing structure provided inside the sealing structure, an air inlet pipe provided inside the sealing structure, and exhaust grooves provided on both sides of the outer wall of the air inlet pipe. The atomizing structure includes a mounting frame and a sliding bar. Integrated vibration components are provided at the four corners of the inner wall of the mounting frame, and microporous atomizing meshes are provided between the four integrated vibration components. A microporous atomizing mesh includes a substrate made of medical-grade corrosion-resistant material. The substrate has an array of micropores arranged on it. The micropores are fabricated using precision micro-nano processing technology and are tapered holes that penetrate the upper and lower surfaces of the substrate.

[0007] Furthermore, the sealing structure includes a housing, with cable ties on both sides of the outer wall of the housing, a flow divider compartment inside the housing, and a flow divider plate on the inner wall of the flow divider compartment, the flow divider plate being inclined.

[0008] Furthermore, mounting compartments are provided on both sides of the outer wall of the housing, a guide groove is provided directly below the mounting compartment, and an adhesive strip is provided at the bottom of the housing.

[0009] Furthermore, the top of the housing is provided with an atomizing shell, the inner walls of the atomizing shell are provided with atomizing chambers on both sides, the inner walls of the atomizing chambers are provided with horizontal grooves, and the top and bottom of the inner walls of the horizontal grooves are provided with slots.

[0010] Furthermore, the disinfectant diversion structure includes an inlet chamber located at the top of the atomizing shell, a guide plate at the bottom of the inlet chamber, a drip nozzle at the bottom of the guide plate, and a threaded tube at the top of the inlet chamber.

[0011] Furthermore, the ventilation structure includes two electric actuators, which are located inside the installation chamber. A lifting plate is provided between the two electric actuators. A connecting strip is provided at the bottom of the lifting plate, and a sealing block is provided at the bottom of the connecting strip.

[0012] Furthermore, sliders are provided on both sides of the mounting frame, and positioning rods are provided on the outer walls of both sides of the mounting frame. The sliders are slidably connected to the inside of the horizontal groove.

[0013] Furthermore, a sliding hole is provided in the middle of the sliding strip, and the sliding strip is slidably connected to the positioning rod through the sliding hole. The number of sliding strips is set to multiple, with two sliding strips forming a group.

[0014] Furthermore, the roller is slidably connected to the inner wall of the horizontal groove, and the roller is engaged with the slot.

[0015] 3. Beneficial effects: Compared with the prior art, the technical solution provided by this invention has the following advantages: This invention generates vibration through an integrated vibration component. The vibration cuts the disinfectant or saline solution dripping onto its surface. When the liquid is squeezed through the micropores by the vibration, it is sheared into uniform micron-sized droplets. Then, the micron-sized droplets move downwards and come into contact with the abrasions on the skin surface, so that the disinfectant or saline solution can fully contact the inside of the tiny gaps in the epidermal abrasions. The four-corner symmetrical integrated vibration components are driven synchronously to solve the problem of uneven vibration of a single oscillator; together with the conical microporous atomizing mesh, it generates uniform micron-sized droplets that can penetrate into tiny gaps and biofilms that are inaccessible by traditional methods, greatly improving the removal rate of bacteria and foreign objects and reducing the risk of infection. The atomizing structure adopts a quick-installation design with sliding installation and torsion spring self-locking, which can be quickly disassembled and replaced to avoid cross-infection. It is suitable for clinical disposable aseptic operation requirements, and the self-locking structure is resistant to high-frequency vibration and loosening, ensuring stable and reliable operation. All parts that come into contact with the medication and the human body are made of medical-grade corrosion-resistant and biocompatible materials, making them compatible with various clinical wound cleaning and disinfection solutions. They can be fixed with cable ties to fit wounds on the limbs, torso, and other parts of the body, and can be used in various scenarios such as hospital emergency rooms, community healthcare, and home care.

[0022] See attached document Figure 1-6 An ultrasonic atomizing wound cleaning device includes a sealing structure 1, disinfectant diversion structures 2 are provided on both sides of the top of the sealing structure 1, ventilation structures 3 are provided on both sides of the inner wall of the sealing structure 1, an atomizing structure 4 is provided inside the sealing structure 1, an air inlet pipe 5 is provided inside the sealing structure 1, and exhaust grooves 6 are provided on both sides of the outer wall of the air inlet pipe 5. The atomizing structure 4 includes a mounting frame 401 and a sliding bar 406. Integrated vibration components 402 are provided at the four corners of the inner wall of the mounting frame 401, and microporous atomizing mesh 403 is provided between the four integrated vibration components 402. The microporous atomizing mesh 403 includes a substrate made of medical-grade corrosion-resistant material. The substrate has an array of micropores, which are fabricated by precision micro-nano processing technology. The micropores are tapered holes that penetrate the upper and lower surfaces of the substrate. The integrated vibration assembly 402 consists of four sets, which are fixedly installed at the four corners of the inner wall of the mounting frame 401 of the atomizing structure 4. The four sets of components are arranged in a symmetrical encircling layout, with a microporous atomizing mesh 403 fixedly installed in the middle to form a stable vibration drive structure.

[0023] This component is the core power unit for the device's atomization function, providing a high-frequency, synchronous mechanical vibration source for the microporous atomizing mesh 403, and is the core driving component for realizing drug liquid atomization.

[0024] The four integrated vibration components 402 adopt a synchronous drive mode, which can drive the microporous atomizing mesh 403 to generate overall and uniform high-frequency resonance, avoiding the problems of uneven mesh vibration and unstable atomization effect caused by single-unit drive, and ensuring the consistency of droplet size and the stability of atomization effect.

[0025] The microporous atomizing mesh 403 uses a substrate made of medical-grade corrosion-resistant material, which can be used with various medical debridement liquids such as disinfectant and saline. It will not cause problems such as material corrosion or release of harmful substances in medical settings, and meets medical biosafety requirements.

[0026] The substrate has an array of uniformly arranged micropores. The micropores are conical holes that penetrate the upper and lower surfaces of the substrate and are the core execution structure for drug atomization. The conical hole structure design can optimize the squeezing and shearing effect of the drug, and improve atomization efficiency and droplet uniformity.

[0027] The micropores are fabricated using precision micro-nano fabrication technology, which ensures the accuracy of the pore size, the consistency of the pore shape, and the uniformity of the array arrangement, providing a core structural basis for generating micron-sized droplets with uniform particle size.

[0028] The microporous atomizing mesh 403 is fixed between four integrated vibration components 402 and can generate high-frequency vibration synchronously with the vibration components to achieve continuous atomization treatment of the surface liquid.

[0029] Furthermore, the sealing structure 1 includes a housing 101, with cable ties 102 on both sides of the outer wall of the housing 101. A flow-diverting chamber 103 is formed inside the housing 101, and a flow-diverting plate 104 is provided on the inner wall of the flow-diverting chamber 103. The flow-diverting plate 104 is inclined. Installation chambers 105 are formed on both sides of the outer wall of the housing 101, and a guide groove 106 is formed directly below the installation chamber 105. An adhesive strip 107 is provided at the bottom of the housing 101. The top of the housing 101 is provided with an atomizing shell 108. Atomizing chambers 109 are provided on both sides of the inner wall of the atomizing shell 108. A horizontal groove 110 is provided on the inner wall of the atomizing chamber 109. The top and bottom of the inner wall of the horizontal groove 110 are provided with slots 111. When a patient has superficial soft tissue injury and needs to be disinfected and the wound cleaned, the straps 102 on the outer wall of the housing 101 are connected to each other, so that the adhesive strip 107 at the bottom of the housing 101 fits against the patient's skin to fix the housing 101.

[0030] Furthermore, the disinfectant diversion structure 2 includes an inlet chamber 201, which is located at the top of the atomizing shell 108. A guide plate 202 is located at the bottom of the inlet chamber 201, and a drip nozzle 203 is located at the bottom of the guide plate 202. A threaded tube 204 is located at the top of the inlet chamber 201. The opened saline solution is then inserted into the threaded tube 204, and the saline solution enters the inlet chamber 201 and is diverted by the guide plate 202, so that the drip nozzle 203 at the bottom of the guide plate 202 drips the saline solution into the atomizing shell 108.

[0031] Furthermore, the ventilation structure 3 includes two electric actuators 301, which are located inside the installation chamber 105. A lifting plate 302 is provided between the two electric actuators 301. A connecting strip 303 is provided at the bottom of the lifting plate 302, and a sealing block 304 is provided at the bottom of the connecting strip 303. The sealing block 304 is slidably connected to the inner wall of the guide groove 106. During wound cleaning, the electric actuators 301 are activated, causing the lifting plate 302 to slide on the inner wall of the installation chamber 105. The lifting plate 302 also causes the connecting strip 303 to move upward. The connecting strip 303 causes the sealing block 304 to retract into the inner wall of the guide groove 106, opening both sides of the housing 101. Oxygen is discharged through the opening, thus guiding the atomized saline solution. The integrated vibration assembly 402 employs four sets of piezoelectric ceramic vibrators. A high-frequency drive signal is synchronously output by an external controller (such as a microcontroller or multi-channel signal generator) to cause all four sets of vibrators to vibrate simultaneously, achieving uniform resonance of the microporous atomizing mesh 403. The electric push rod 301 is electrically connected to the controller, which controls its extension and retraction according to the debridement process sequence, thus achieving automatic opening and closing of the ventilation structure 3.

[0032] Furthermore, sliders 404 are provided on both sides of the mounting frame 401, and positioning rods 405 are provided on the outer walls of both sides of the mounting frame 401. The sliders 404 are slidably connected to the inside of the horizontal groove 110. A sliding hole 407 is provided in the middle of the sliding strip 406. The sliding strip 406 is slidably connected to the positioning rod 405 through the sliding hole 407. The number of sliding strips 406 is set to multiple, with two sliding strips 406 forming a group. Rotating strips 408 are rotatably connected to the top and bottom of a group of sliding strips 406. Rollers 409 are rotatably connected between two rotating strips 408. 409 is slidably connected to the inner wall of the horizontal groove 110. The roller 409 is engaged with the slot 111. Then, the atomizing structure 4 is installed inside the sealing structure 1. The mounting frame 401 is pushed into the interior of the atomizing shell 108 from the notch on one side of the top of the atomizing shell 108, so that the mounting frame 401 enters the interior of the horizontal groove 110. A torsion spring is provided at the connection position of the sliding bar 406 and the rotating bar 408. The torsion spring resets and drives the sliding hole 407 inside the sliding bar 406 to slide on the positioning rod 405. The sliding bar 406 drives the rotating bar 408 to rotate and push the roller 409 into the inner wall of the slot 111 for fixation. The integrated vibration assembly 402 is activated, which drives the microporous atomizing mesh 403 to vibrate. The vibration breaks the saline solution into particles and passes through the microporous atomizing mesh 403, so that the saline solution is atomized and enters the interior of the housing 101. The oxygen tube is connected to the air inlet pipe 5, and the oxygen enters the interior of the air inlet pipe 5 and is discharged through the exhaust groove 6. The oxygen carries the atomized saline solution through the diverter plate 104 for guidance and then contacts the wound to clean the inner wall of the wound.

[0033] The drip nozzle 203 at the bottom drips evenly onto the surface of the microporous atomizing mesh 403 of the atomizing structure 4, completing the uniform supply of the medicine. The four integrated vibration components 402 are started synchronously, generating high-frequency mechanical vibration and driving the microporous atomizing mesh 403 to resonate at a high frequency as a whole. The high-frequency vibration continuously cuts the medicine on the surface of the microporous atomizing mesh 403. Under the action of vibration and compression, the medicine flows into the conical micropores of the microporous atomizing mesh 403. In the process of passing through the through conical micropores, it is sheared into micron-sized droplets with uniform particle size, completing the ultrasonic atomization process of the medicine.

[0034] After the saline solution is atomized, oxygen continuously enters the interior of the housing 101 to expel the saline solution. Then, disinfectant is placed inside the threaded tube 204, and the wound is disinfected according to the above procedure.

[0035] The mounting frame 401 of the atomizing structure 4 is pushed into the atomizing chamber 109 from the side notch of the atomizing shell 108, so that the sliders 404 on both sides of the mounting frame 401 are embedded in the horizontal groove 110; the torsion spring resets and drives the sliding bar 406 to slide along the positioning rod 405, pushing the rotating bar 408 to rotate, so that the roller 409 is locked into the slot 111 to complete the self-locking installation of the atomizing structure 4.

[0036] Seal and connect the medical saline and disinfectant containers to the threaded tube 204, and seal and connect the medical oxygen pipeline to the external air inlet end of the air inlet pipe 5 to complete the pipeline connection.

[0037] Align the adhesive strip 107 at the bottom of the housing 101 with the outer periphery of the patient's epidermal abrasion wound, and secure it by wrapping the limb with the straps 102 on both sides, so that the adhesive strip 107 fits tightly with the skin, forming a sealed debridement cavity between the shunt chamber 103 and the wound, preventing leakage of medication and intrusion of contaminants.

[0038] Open the medicine container, and the saline solution and disinfectant enter the inlet chamber 201 through the threaded tube 204. After being diverted by the guide plate 202, they are evenly dripped onto the upper surface of the microporous atomizing mesh 403 through the array of drip nozzles 203.

[0039] Four sets of integrated vibration components 402 are activated to synchronously generate high-frequency ultrasonic vibrations and drive the microporous atomizing mesh 403 to resonate as a whole; the high-frequency vibration cuts the liquid medicine, and the liquid medicine passes through the conical micropores under the vibration and compression, and is sheared into micron-sized droplets with uniform particle size, thus completing the liquid medicine atomization.

[0040] The atomized droplets enter the diversion chamber 103 from the atomization chamber 109. The oxygen valve is opened, and oxygen enters the diversion chamber 103 through the air inlet pipe 5 and is sprayed out in a direction through the exhaust slot 6. The droplets are driven to evenly cover the wound surface along the inclined diversion plate 104, penetrating into the tiny gaps in the epidermis and the interior of the biofilm, achieving thorough wound cleaning and disinfection without contact. During the disinfection and cleaning process, the ventilation structure 3 is also in the open state.

[0041] After completing the atomized debridement, the drug supply and integrated vibration component 402 are turned off, and the electric push rod 301 is activated to drive the sealing block 304 to slide upward and disengage from the vent, opening the airflow channel between the diversion chamber 103 and the outside world; oxygen is continuously introduced to drive the humid airflow in the cavity to be discharged, so as to achieve rapid drying of the wound and complete the entire debridement operation.

[0042] The above-described embodiments are merely illustrative of certain implementations of the present invention, and are described in a relatively specific and detailed manner. However, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
