[0002] Wound debridement and repair systems and atomizing nozzles are equipment components used in the medical field. Their core function is to atomize liquid medicine into tiny particles, evenly covering the wound surface to improve liquid medicine absorption efficiency and reduce the risk of spattering.

[0003] Existing atomizing nozzles are generally equipped with an anti-splash structure to prevent the drug solution from splashing onto non-wound areas of medical staff or patients due to improper injection pressure or operation angle, causing cross-infection or waste of drug solution. However, the anti-splash structure requires the entire nozzle to be disassembled for cleaning or replacement of parts, and the existing quick-release structure (such as threaded connection) requires multiple rotations and locking, which is inconvenient to operate.

[0004] To this end, we propose a wound debridement and repair system and a medical atomizing nozzle. Summary of the Invention

[0011] Furthermore, the arc-shaped plate is provided with movable grooves, and the movable plate rotates in two movable grooves at the same time, and the movable grooves and the movable plate are in an arc-shaped structure.

[0012] Furthermore, first magnetic plates are provided at both ends of the movable plate, and second magnetic plates are provided on the end surfaces of the two movable grooves to repel and cooperate with the first magnetic plates, and the corresponding surfaces of the first magnetic plate and the second magnetic plate are inclined.

[0013] Furthermore, a limiting ring groove is provided at the bottom of the arc-shaped plate, and a limiting ring is fixedly connected to the central axis of the protective cover and slides in the limiting ring groove.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] When the wound area and depth are serious and the impact of the disinfectant liquid is strong, a protective cover needs to be installed;

[0020] First, insert the two curved plates and the protective cover along the nozzle rod, and move the curved plates so that the two curved plates move along the movable plate at the same time.

[0042] 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.

[0043] See also Figures 1-19 The present invention provides a wound debridement and repair system and a medical atomizing nozzle thereof. In the wound debridement and repair system, a storage tank is used to store a disinfectant liquid (cleaning liquid) for flushing the wound. When flushing the wound, the medical staff holds the protective shell 1 and aligns the nozzle rod 4 and the spray hole slot 6 with the wound position. The disinfectant liquid in the storage tank enters the delivery pipe 23 through the delivery pump, and is accelerated through the booster device (the impact force of the disinfectant liquid is adjusted by the booster device, thereby adjusting the impact force according to the severity of the wound) to accelerate the delivery efficiency of the disinfectant liquid in the delivery pipe 23, so that the disinfectant liquid quickly enters the obliquely distributed connecting pipe 7, and the connecting pipe 7 is connected to the rotating cylinder 5. The disinfectant liquid enters the rotating cylinder 5 and is finally sprayed out through the spray hole slot 6 to impact the wound and clean the wound.

[0044] The diameter of the spray hole slot 6 gradually decreases from top to bottom, further increasing the impact effect of the disinfectant liquid and ensuring the debridement efficiency;

[0045] The connecting pipe 7 and the delivery pipe 23 are detachably connected, which is convenient for storage and cleaning;

[0046] The protective shell 1 of the medical atomizing nozzle is a hollow shell. The top inner wall of the protective shell 1 is a threaded groove. The external thread on the threaded joint 2 is threadedly connected to the threaded groove of the protective shell 1. The threaded joint 2 is connected to a flexible tube 15. A cable is arranged in the flexible tube 15. One end of the cable is connected to the power supply and the background control system (computer system) on the debridement workbench. The other end of the cable passes through the threaded joint 2 and is connected to the control board of the transducer 8. The control board of the transducer 8 is connected to the output plates of the two transducers 8 through another section of cable. The threaded joint 2 is provided with a buckle for fixing the local position of the cable to prevent excessive movement of the cable (the cable has a certain degree of slack and is not straight).

[0047] There are two semi-cylindrical movable cylinders 14 assembled with each other in the middle of the protective shell 1. The output piece of the transducer 8 is located in the movable cylinder 14. The output piece of the transducer 8 acts on both sides of the core 3 that penetrates the movable cylinder 14. The function of the transducer 8 is to generate ultrasonic vibration: the mechanical vibration generated by the transducer 8 is transmitted to the disinfectant liquid in the form of ultrasonic waves. This high-frequency vibration forms a standing wave on the surface of the disinfectant liquid, so that capillary waves are generated on the surface of the disinfectant liquid. When the amplitude of the wave reaches a critical value, the droplets fall off from the wave crest to form atomization. The transducer 8 in this application can use the ultrasonic atomization transducer manufactured by Beijing Dongfang Jinrong Ultrasonic Electric Co., Ltd.

[0048] The core 3 passes through the protective shell 1 and is fixedly connected to the nozzle rod 4, which is rotatably connected to the rotating cylinder 5. One end of the spray hole groove 6 of the nozzle rod 4 is located in the inner cavity of the rotating cylinder 5. The top and bottom ends of the rotating cylinder 5 are sealed with the nozzle rod 4. There is a certain gap between the middle of the inner cavity of the rotating cylinder 5 and the nozzle rod 4, which facilitates the disinfection liquid to enter the spray hole groove 6 through the gap;

[0049] A snap-fit ​​groove is provided on the side of the threaded joint 2, through which the flexible infusion tube is fixed to prevent the delivery tube 23 from shaking under the rapid action of the disinfectant liquid when flushing the wound;

[0050] In the present application, a detachable and installable protective cover 9 is also provided (a transparent protective cover 9, with an organic silicon coating applied on the protective layer: organic silicon compounds can also form a hydrophobic coating on the surface of the material, such as polydimethylsiloxane (PDMS), which is not only hydrophobic but also has good flexibility and chemical stability. In addition, polydimethylsiloxane appears as a colorless, transparent volatile liquid or a high-viscosity liquid at a low relative molecular mass, and has extremely high transparency and light transmittance).

[0051] When the wound area and depth are more serious and the impact force of the disinfectant liquid is strong, a protective cover 9 is needed to prevent the medical staff from splashing back to the position where the protective shell 1 is held;

[0052] First, insert the two curved plates 10 and the protective cover 9 along the nozzle rod 4. The two curved plates 10 are placed on the outer wall of the rotating cylinder 5 and touch the inclined connecting pipe 7.

[0053] Then, the thumb and ring finger are used to move the paddle block on the arc-shaped plate 10, so that the two arc-shaped plates 10 rotate toward each other, and the two arc-shaped plates 10 move simultaneously along the movable plate 13. The two second magnetic plates 18 simultaneously move toward the two first magnetic plates 17, thereby moving the two first through holes 11 away from each other, making it easier for the connecting pipe 7 to pass through the two first through holes 11 away from each other and enter the second through hole 12. The length of the movable plate 13 is set so that the two ends of the movable plate 13 will never leave the movable groove 16. When moving the paddle block, no excessive force is required, and the arc of rotation of the arc-shaped plate 10 does not need to be too large.

[0054] Finally, release the force applied by your fingers on the curved plate 10. Under the repulsive action of the first magnetic plate 17 and the second magnetic plate 18, the two first through holes 11 are reunited. The cooperation of the two first through holes 11 and the second through hole 12 presses the connecting pipe 7 together, so that the inner wall of the curved plate 10 and the middle part of the protective cover 9 are attached to the outer wall of the rotating cylinder 5. At the same time, the cooperation of the first through holes 11 and the second through holes 12 on the connecting pipe 7 further strengthens the stable connection between the rotating cylinder 5 and the protective cover 9. This method is convenient and quick to operate.

[0055] It is worth noting that the two first through holes 11 are of different sizes and are assembled into a semi-cylindrical shape, so that the contact point of the two curved plates 10 is located on the side of the connecting tube 7, not on the central axis of the connecting tube 7 (deviation relationship). The connecting tube 7 presses against the two curved plates 10 and is prevented from being pressed out of the two first through holes 11. The connecting tube 7 can only be released by manually moving the curved plates 10 to open the first through holes 11, effectively ensuring that the protective cover 9 is stably mounted on the rotating cylinder 5.

[0056] When the arc plate 10 rotates, the arc plate 10 is restricted by the limiting ring groove 19 at the bottom of the arc plate 10 and the limiting ring 20 at the center axis of the protective cover 9 to ensure smooth rotation of the arc plate 10;

[0057] The corresponding surfaces of the first magnetic plate 17 and the second magnetic plate 18 are inclined. Under the action of the repulsive force, the top of the movable plate 13 is pressed against the top of the movable groove 16, so that the top of the movable plate 13 is pressed against the two curved plates 10, ensuring the relative position of the two curved plates 10 and preventing the two curved plates 10 from automatically moving closer to each other (without the force applied by the fingers).

[0058] Among them, inclined surfaces 21 are provided on both sides of the bottom of the limiting ring 20. When the connecting pipe 7 is located in the two first through holes 11 and the second through hole 12, the connecting pipe 7 reacts on the arc plate 10 to make the limiting ring groove 19 on the arc plate 10 move in the vertical direction away from the limiting ring 20, so that the inclined surface 21 is pressed and contacted with the inclined groove of the limiting ring groove 19. The contact surface of the upward-moving inclined surface 21 and the limiting ring groove 19 is a friction surface. The inclined surface 21 is pressed and contacted with the inclined groove of the limiting ring groove 19 to prevent the limiting ring 20 from sliding on the limiting ring groove 19 in the horizontal direction, thereby ensuring the splicing and matching of the two first through holes 11 and the second through hole 12, and firmly pressing the connecting pipe 7.

[0059] It is worth noting that: the end of the limiting ring 20 is an elastic extrusion end 22, and the elastic extrusion end 22 of the limiting ring 20 is extruded and matched with the connecting pipe 7. When the connecting pipe 7 is located in the second through hole 12, the elastic extrusion end 22 of the limiting ring 20 presses on the connecting pipe 7, and the pressing position is located above the central axis of the connecting pipe 7. The pressing direction effectively makes the connecting pipe 7 tightly pressed in the second through hole 12, and the elastic extrusion end 22 and the limiting ring groove 19 are frictionally matched. The connecting pipe 7 reacts on the elastic extrusion end 22 of the limiting ring 20, so that the elastic extrusion end 22 of the limiting ring 20 is squeezed and deformed (the elastic deformation amount is constant and does not exceed the yield strength and elastic modulus), so that the deformed elastic extrusion end 22 of the limiting ring 20 directly presses and contacts the limiting ring groove 19, reducing the sliding between the elastic extrusion end 22 and the curved plate 10;

[0060] Among them, the elastic extrusion end 22 of the limiting ring 20 is a detachable and replaceable structure, which can be replaced by plugging or gluing to avoid permanent deformation and excessive wear of the elastic extrusion end 22, which would affect its functional use.
