Description

Technical Field

[0001] This invention relates to the field of wound cleaning nozzle structure technology, specifically to a wound cleaning and repair system and a medical atomizing nozzle. Background Technology

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

[0003] Existing atomizing nozzles are generally equipped with anti-splash structures to prevent the medication from splashing onto non-wound areas of medical staff or patients due to improper spray pressure or operating angle, which could lead to cross-infection or waste of medication. However, the anti-splash structure requires the entire nozzle to be disassembled for cleaning or replacement of parts, and existing quick-release structures (such as threaded connections) require multiple rotations to tighten, which is inconvenient.

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

[0005] The purpose of this invention is to provide a wound debridement and repair system and a medical atomizing nozzle to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides a medical atomizing nozzle for a wound debridement and repair system, comprising a protective shell and a threaded connector, wherein the threaded connector is threadedly connected to the top of the protective shell, a core is movably inserted through the middle of the protective shell, and a nozzle rod is provided at the bottom of the core;

[0007] It also includes a rotating cylinder, the nozzle rod has a spray hole groove, the rotating cylinder is fixedly connected to a connecting pipe, the inner cavity of the rotating cylinder is connected and fitted with the spray hole groove, the threaded joint is provided with a transducer, and the output shaft of the transducer is connected and fixed to the core.

[0008] The protective cover is sleeved with the rotating cylinder. The central axis of the protective cover is rotatably connected to two arc-shaped plates. The arc-shaped plates have two first through holes, and the protective cover has a second through hole. The two first through holes and the second through hole cooperate to engage the connecting pipe. A movable plate is slidably engaged between the two arc-shaped plates.

[0009] Furthermore, the protective housing contains two movable cylinders that are interlocked with each other, and the transducer has two output plates distributed on both sides of the movable cylinders. The transducer's control board is snapped between the two movable cylinders.

[0010] Furthermore, a flexible tube containing a cable is fixedly connected to the protective housing, the control board of the transducer is connected to the cable, and the threaded joint is provided with a buckle to restrict the cable.

[0011] Furthermore, the arc-shaped plate is provided with movable grooves, and the movable plate rotates simultaneously in two movable grooves, with the movable grooves and the movable plate forming an arc-shaped structure.

[0012] Furthermore, the movable plate is provided with a first magnetic suction plate at both ends, and the end faces of the two movable slots are provided with a second magnetic suction plate that repulses and cooperates with the first magnetic suction plate. The corresponding surfaces of the first magnetic suction plate and the second magnetic suction plate are inclined at an angle.

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

[0014] Furthermore, inclined surfaces are provided on both sides of the bottom of the limiting ring, and the contact surface between the upward-moving inclined surface and the groove of the limiting ring is a friction surface.

[0015] Furthermore, the end of the limiting ring is an elastic extrusion end, which is extruded into the connecting pipe and frictionally engaged with the groove of the limiting ring.

[0016] Furthermore, the two first through holes are of different sizes, and the two first through holes are pieced together to form a semi-cylindrical shape.

[0017] A wound debridement and repair system includes a medical atomizing nozzle for the aforementioned wound debridement and repair system, and a delivery pipe connected to a connecting pipe. The delivery pipe has a storage tank at its end, a delivery pump on the storage tank, a pressurizing device in the middle of the delivery pipe, and a snap-fit ​​groove on the side of the threaded joint for engaging with the delivery pipe.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] When the wound area and depth are relatively serious and a strong impact of disinfectant is required, a protective shield needs to be installed.

[0020] First, insert the two arc-shaped plates and the protective cover along the nozzle rod. Move the arc-shaped plates so that they move simultaneously along the movable plate. Under the action of the first and second magnetic suction plates, the two first through holes move away from each other, making it easier for the connecting tube to enter the second through hole. Finally, under the repulsive action of the first and second magnetic suction plates, the two first through holes merge back together. The cooperation of the two first through holes and the second through hole together presses against the connecting tube. The inner wall of the arc-shaped plate and the middle of the protective cover fit against the outer wall of the rotating cylinder, further strengthening the stable connection between the rotating cylinder and the protective cover. This method is convenient and quick to operate.

[0021] The elastic extrusion end acts on the connecting pipe and the limiting ring groove, and the inclined surface cooperates with the limiting ring groove to enhance the stability of the protective cover after installation. Attached Figure Description

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0043] Please see Figures 1-19 This invention provides a wound cleaning and repair system and its medical atomizing nozzle. In the wound cleaning and repair system, the storage tank is used to store disinfectant liquid (cleaning solution) for rinsing the wound. When rinsing the wound, medical staff hold the protective shell 1 and align the nozzle rod 4 and the spray slot 6 with the wound. Through the delivery pump, the disinfectant liquid in the storage tank enters the delivery pipe 23. Through the pressurization device (which adjusts the impact force of the disinfectant liquid according to the severity of the wound), the delivery efficiency of the disinfectant liquid in the delivery pipe 23 is accelerated, so that the disinfectant liquid quickly enters the inclined connecting pipe 7. The connecting pipe 7 connects to the rotating cylinder 5. The disinfectant liquid enters the rotating cylinder 5 and is finally sprayed out through the spray slot 6 to impact the wound and clean it.

[0044] The diameter of the spray nozzle 6 gradually decreases from top to bottom, further increasing the impact of the disinfectant liquid and ensuring the efficiency of wound cleaning.

[0045] The connecting pipe 7 and the conveying pipe 23 are detachably connected, making them easy to store and clean.

[0046] The protective housing 1 of the medical atomizing nozzle is a hollow housing. The inner top wall of the protective housing 1 is a threaded groove. The external thread on the threaded connector 2 is threadedly connected to the threaded groove of the protective housing 1. A flexible tube 15 is connected to the threaded connector 2. A cable is installed inside the flexible tube 15. One end of the cable is connected to the power supply and the background control system (computer system) on the wound cleaning workbench. The other end of the cable passes through the threaded connector 2 and connects 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 cable. The threaded connector 2 is provided with a buckle to fix the local position of the cable to prevent the cable from moving excessively (the cable has a certain degree of slack and is not taut).

[0047] The protective housing 1 has two semi-cylindrical movable cylinders 14 that are assembled with each other in the middle. The output plate of the transducer 8 is located in the movable cylinder 14. The output plate of the transducer 8 acts on both sides of the core 3 that penetrates into 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, which causes capillary waves to be generated on the surface of the disinfectant liquid. When the amplitude of the wave reaches the critical value, the droplets fall off from the wave crest and form atomization. The transducer 8 in this application can be an ultrasonic atomizing transducer manufactured by Beijing Dongfang Jinrong Ultrasonic Electric Co., Ltd.

[0048] The core 3 extends out of the protective shell 1 and is connected and fixed to the nozzle rod 4. The nozzle rod 4 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 to 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 disinfectant liquid to enter the spray hole groove 6 through the gap.

[0049] The threaded connector 2 has a snap-fit ​​groove on one side, which is used to snap and fix the flexible infusion tube to prevent the delivery tube 23 from shaking under the action of the rapid disinfectant liquid when rinsing the wound.

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

[0051] When the wound area and depth are relatively serious and a strong impact of the disinfectant liquid is required, the protective cover 9 is needed to prevent back splashing onto the position of the protective shell 1 held by medical staff.

[0052] First, fit the two arc-shaped plates 10 and the protective cover 9 along the nozzle rod 4. The two arc-shaped plates 10 are fitted onto the outer wall of the rotating cylinder 5 and touch the inclined connecting pipe 7.

[0053] Then, by using the thumb and ring finger to move the lever on the arc plate 10, the two arc plates 10 rotate closer to each other. The two arc plates 10 move along the movable plate 13 at the same time, and the two second magnetic plates 18 move closer to the two first magnetic plates 17 at the same time, so that the two first through holes 11 move away from each other, so that the connecting tube 7 can pass through the two distant first through holes 11 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, and when moving the lever, excessive force is required, and the rotation arc of the arc plate 10 does not need to be too large.

[0054] Finally, the force applied to the arc plate 10 is released. Under the repulsive action of the first magnetic plate 17 and the second magnetic plate 18, the two first through holes 11 are rejoined. The cooperation of the two first through holes 11 and the second through hole 12 together presses against the connecting pipe 7, thereby making the inner wall of the arc plate 10 and the middle part of the protective cover 9 fit against the outer wall of the rotating cylinder 5. At the same time, the cooperation of the first through hole 11 and the second through hole 12 with 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 pieced together to form a semi-cylindrical shape. This causes the contact points of the two arc plates 10 to be located on the side of the connecting pipe 7, not on the central axis of the connecting pipe 7 (offset relationship). This causes the connecting pipe 7 to press against the two arc plates 10, preventing it from being pushed out of the two first through holes 11. This means that the connecting pipe 7 can only be released by manually moving the arc plates 10 to open the first through holes 11, effectively ensuring that the protective cover 9 is stably installed on the rotating cylinder 5.

[0056] When the arc plate 10 rotates, the limiting ring groove 19 opened at the bottom of the arc plate 10 and the limiting ring 20 at the central axis of the protective cover 9 ensure the smooth rotation of the arc plate 10.

[0057] The surfaces of the first magnetic plate 17 and the second magnetic plate 18 are inclined at an angle. Under the action of repulsive force, the top of the movable plate 13 presses against the top of the movable groove 16, thereby pressing the top of the movable plate 13 against the two arc plates 10, ensuring the relative position of the two arc plates 10, and preventing the two arc plates 10 from automatically moving closer to each other (without the force of the fingers).

[0058] The limiting ring 20 has inclined surfaces 21 on both sides of its bottom. 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 to the arc plate 10, causing the limiting ring groove 19 on the arc plate 10 to move vertically away from the limiting ring 20. This causes the inclined surface 21 to press against the inclined groove of the limiting ring groove 19. The contact surface between the upward-moving inclined surface 21 and the limiting ring groove 19 is a friction surface. The pressing contact between the inclined surface 21 and the inclined groove of the limiting ring groove 19 prevents the limiting ring 20 from sliding on the limiting ring groove 19 in the horizontal direction, thereby ensuring the splicing and cooperation of the two first through holes 11 and the second through hole 12, and providing a stable pressing effect on the connecting pipe 7.

[0059] It is worth noting that the end of the limiting ring 20 is an elastic compression end 22. The elastic compression end 22 of the limiting ring 20 is in compression fit with the connecting pipe 7. When the connecting pipe 7 is located in the second through hole 12, the elastic compression end 22 of the limiting ring 20 presses against the connecting pipe 7, and the pressing position is located at the upper part of the central axis of the connecting pipe 7. The pressing direction effectively makes the connecting pipe 7 tightly press against the second through hole 12. The elastic compression end 22 is in friction fit with the limiting ring groove 19. The connecting pipe 7 reacts to the elastic compression end 22 of the limiting ring 20, causing the elastic compression end 22 of the limiting ring 20 to be compressed and deformed (the elastic deformation is constant and does not exceed the yield strength and elastic modulus). Thus, the deformed elastic compression end 22 of the limiting ring 20 directly presses against the limiting ring groove 19, reducing the sliding between the elastic compression end 22 and the arc plate 10.

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