Description

Technical Field

[0001] This invention relates to the field of clinical nursing technology, and in particular to a multifunctional integrated wound debridement and negative pressure drainage nursing device for clinical nursing. Background Technology

[0002] Wound debridement refers to the treatment of removing non-living tissue, blood clots, foreign bodies, and other harmful substances from a wound or lesion. It is of great significance in preventing or reducing local infection, improving local blood circulation, and promoting the repair of damaged tissue. Negative pressure drainage, on the other hand, applies negative pressure to the wound to absorb exudate and promote wound healing. Effective wound management is crucial for patient recovery. Currently, wound debridement and negative pressure drainage are usually performed using different instruments, which is cumbersome and prone to secondary contamination of the wound during instrument switching.

[0003] To address the cumbersome operation of using different instruments, a certain flushing and negative pressure drainage debridement device on the market adopts an integrated design and has a certain market share.

[0004] A search revealed that patent CN217430541U discloses a handheld irrigation and negative pressure drainage debridement device. The handle contains two independent cavities: a first receiving cavity and a second receiving cavity, both open at both ends. The first and second receiving cavities are respectively equipped with an irrigation mechanism and a negative pressure drainage mechanism, which are slidably connected to the inner walls of the first and second receiving cavities. This debridement device offers multiple functions, integrating wound cleaning and negative pressure drainage, thus improving the speed of wound treatment and providing convenience for medical personnel during treatment, eliminating the need for frequent changes of medical devices.

[0005] Based on the above research, existing debridement and negative pressure drainage devices, when removing foreign bodies and necrotic tissue from deep wounds, sometimes have larger foreign bodies and tissues that are absorbed by the negative pressure device immediately and become stuck at the drainage tube opening. This can cause blockage of the drainage tube, resulting in insufficient drainage and affecting the overall use of the device. Therefore, a multifunctional integrated wound debridement and negative pressure drainage nursing device for clinical nursing is proposed to improve the above problems. Summary of the Invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that some large foreign objects and tissues are absorbed by the negative pressure device at the first time and get stuck at the drainage tube opening. This will cause the drainage tube to be blocked, resulting in insufficient drainage of the negative pressure drainage device and affecting the use of the entire device.

[0013] The present invention is further configured such that a first protective pad is fixed to the bottom of the protective cover, and a second protective pad is fixed to the bottom of the suction tube.

[0014] The present invention is further configured such that the integrated wound cleaning and drainage component includes a first mounting hole opened at the middle of the top of the two drainage cylinders, and a first drive shaft is rotatably connected to the inner wall of the first mounting hole via a sealed bearing; a second mounting hole is opened at the middle of the top of the suction cylinder, and a second drive shaft is rotatably connected to the inner wall of the second mounting hole via a sealed bearing; auger blades that fit against the inner walls of the suction cylinder and the drainage cylinder are installed on the outer walls of the second drive shaft and the outer walls of the first drive shaft; gears are installed at the top ends of the first drive shaft and the second drive shaft, and the three gears mesh in sequence; a driver for driving the second drive shaft to rotate is installed on the top of the support plate; a suction pipe communicating with the storage chamber is fixed on one side of the top of each of the two drainage cylinders, and a discharge pipe communicating with the storage chamber is fixed on one side of the top of the suction cylinder; a one-way valve is installed at the top end of the discharge pipe.

[0018] In summary, by adopting the above structure, the present invention has the following advantages compared with the prior art:

[0019] 1. By using the above-mentioned integrated wound cleaning and drainage component and nozzle component, the functions of wound cleaning and negative pressure drainage can be integrated. The ultrasonic generator inside the nozzle component effectively utilizes the cavitation effect of ultrasound to transform the cleaning fluid into microbubbles. When these bubbles come into contact with the wound, they burst and generate a strong impact force, effectively removing dirt, necrotic tissue, and bacteria from the wound surface. At the same time, the waste generated during cleaning is transported to the storage chamber for storage through negative pressure, improving nursing efficiency and reducing operation steps.

[0020] 2. Using the above-mentioned nozzle assembly, the bottom of the nozzle is designed as an upward-protruding umbrella shape, and the spray needle is designed as an inclined shape. This can concentrate the bubbles sprayed from the spray needle in one place, increase the impact force generated by the bursting of bubbles, and fully improve the wound cleaning effect. It also allows some of the bursting bubbles to be blown at high speed at the inlet of the suction tube, effectively removing and breaking up larger foreign objects and tissues absorbed by the suction tube. This avoids the problem that larger foreign objects and tissues are difficult to be absorbed by the negative pressure device, and prevents the entire drainage pipe from becoming blocked.

[0021] 3. The use of the aforementioned angle-adjustable components, annular groove, fixing ring, and spring allows for flexible adjustment of the angle between the outer shell and the protective cover. This facilitates operation by nursing staff according to different wound locations and angles, improving ease of use and adaptability. While ensuring adjustability, the height of the outer shell and nozzle can also be adjusted, ensuring that the nozzle assembly remains close to the wound when changing its angle, thus improving work efficiency.

[0022] 4. The miniature lighting described above can provide illumination during wound cleaning, allowing nursing staff to observe the wound condition more clearly, which helps to perform the operation more accurately and improve the cleaning effect.

[0023] 5. The aforementioned crushing blade can synchronously drive the crushing blade on the connecting shaft to rotate when the driver is working, which facilitates the crushing of waste materials entering the storage chamber, reduces the volume of waste materials, and facilitates subsequent discharge.

[0041] Reference Figures 1-12This invention provides a multifunctional integrated wound debridement and negative pressure drainage nursing device for clinical nursing, including a shell 1 and a protective cover 4. An angle-adjustable component is provided between the shell 1 and the protective cover 4. Two support plates 11 are fixed to the inner wall of the shell 1 near the bottom. A suction cylinder 13 and two drainage cylinders 14 are installed on the two support plates 11. The suction cylinder 13 is located between the two drainage cylinders 14 and in the middle of the shell 1. A suction tube 26 and a drainage tube 24 extending out of the shell 1 are respectively fixed to the bottom of the suction cylinder 13 and the bottom of the drainage cylinder 14. Two partition plates 16 are fixed to the inner wall of the shell 1, and the two partition plates 16 divide the upper part of the shell 1 into a material storage chamber 41 and a liquid storage chamber 40 from top to bottom. An integrated wound debridement and drainage component is provided inside the suction cylinder 13, the material storage chamber 41, the drainage cylinder 14, and the liquid storage chamber 40. The system includes a first mounting hole located at the middle of the top of the two drain cylinders 14, and a first drive shaft 22 is rotatably connected to the inner wall of the first mounting hole via a sealed bearing. A second mounting hole is located at the middle of the top of the suction cylinder 13, and a second drive shaft 27 is rotatably connected to the inner wall of the second mounting hole via a sealed bearing. Screw blades 23 that fit against the inner walls of the suction cylinder 13 and the drain cylinder 14 are installed on the outer walls of the second drive shaft 27 and the first drive shaft 22. Gears 44 are installed at the top of both the first drive shaft 22 and the second drive shaft 27, and the three gears 44 mesh in sequence. A driver 15 for driving the second drive shaft 27 to rotate is installed on the top of the support plate 11. A suction pipe 45 communicating with the storage chamber 40 is fixed on one side of the top of each of the two drain cylinders 14, and a discharge pipe 28 communicating with the storage chamber 41 is fixed on one side of the top of the suction cylinder 13. A one-way valve is installed at the top of the discharge pipe 28.

[0042] A threaded connector 25 is fixed to the bottom of the outer casing 1, and a nozzle assembly 12 is threaded onto the inner wall of the threaded connector 25. The nozzle assembly 12 includes a nozzle 1201 threaded into the threaded connector 25, and the bottom of the nozzle 1201 is designed as an upwardly convex umbrella shape. An insertion hole for the suction pipe 26 to pass through is opened at the middle of the bottom of the nozzle 1201. Multiple rows of equally spaced, annularly distributed spray needles 1202 are fixed to the bottom of the nozzle 1201, and the spray needles 1202 are designed as inclined. A super-fastener is installed on the inner wall of the bottom of the outer casing 1. The ultrasonic generator 1204 is equipped with an ultrasonic vibration plate 1203 installed at the bottom of the nozzle 1201. A sealing groove is formed on the top of the inner wall of the nozzle 1201, and a sealing ring 29 fitted into the sealing groove is installed at the bottom of the outer casing 1. A sealing gasket 31 is installed on the outer wall of the suction pipe 26, and the sealing gasket 31 is fitted into the middle of the bottom inner wall of the nozzle 1201. The second drive shaft 27 and the auger blade 23 on it are driven to rotate forward by the driver 15, and the gears are engaged. The meshing action of wheel 44 drives the first drive shaft 22 and its auger blades 23 to reverse, thereby causing the debridement fluid in the storage chamber 40 to be sprayed at high speed along the drain pipe 24 into the nozzle 1201 under the action of the auger blades 23 in the drain cylinder 14. The cavitation effect of the ultrasonic waves in the ultrasonic generator 1204 is used to convert the debridement fluid into microbubbles. When the bubbles come into contact with the wound, they burst and generate a strong impact force, which can remove dirt and other substances from the wound surface. At the same time, the auger blades 23 in the suction cylinder 13 create a negative pressure, which causes the debridement waste fluid and foreign objects to enter the storage chamber 41 along the drain pipe 28 for storage. The bubbles sprayed by the spray needle 1202 are concentrated in one place, which increases the impact force generated by the bursting of the bubbles and fully improves the debridement effect. Some of the bursting bubbles are blown at high speed at the opening of the suction pipe 26, which effectively removes and breaks up larger foreign objects and tissues absorbed by the suction pipe 26, avoiding the problem that larger foreign objects and tissues are difficult to be absorbed by the negative pressure device and preventing the entire drainage pipe from becoming blocked.

[0043] In this invention, a plurality of annular miniature lighting lamps 32 are installed on the bottom outer wall of the nozzle 1201, and the positions of the miniature lighting lamps 32 intersect with the positions of the spray needles 1202, such as... Figure 6 As shown, the aforementioned miniature lighting lamp 32 facilitates clear observation of the wound interior during the debridement process.

[0044] In this invention, the angle-adjustable component includes an annular support 3 installed on the inner wall of the top of the protective cover 4, and the inner wall of the annular support 3 is spherical. A universal ball 2, fitted to the inner wall of the outer shell 1, is located at the bottom of the outer wall of the outer shell 1. A central hole is formed in the middle of the universal ball 2, and the outer shell 1 passes through the central hole. An annular groove 36 is formed in the middle of the inner wall of the central hole. A fixing ring 37, inserted into the annular groove 36, is installed on the outer wall of the outer shell 1. Springs 39, evenly distributed, are installed at the bottom of the fixing ring 37 and the bottom of the annular groove 36. Guide holes, evenly distributed, are formed on the fixing ring 37, and guide posts 38, passing through the guide holes, are fixed to the inner wall of the annular groove 36. The protective cover 4 and the annular support 3 are designed to be transparent. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 and Figure 9 By using the aforementioned angle-adjustable components and spring 39, the angle between the outer shell 1 and the protective cover 4 can be flexibly adjusted, making it convenient for nursing staff to operate according to different wound locations and angles. While ensuring adjustability, the height of the outer shell 1 and the nozzle assembly 12 can also be adjusted, so that when changing the angle of the nozzle assembly 12, it can still be close to the wound, thus improving work efficiency.

[0045] In this invention, a first protective pad 5 is fixed to the bottom of the protective cover 4, and a second protective pad 30 is fixed to the bottom of the suction pipe 26, such as... Figure 1 , Figure 2 , Figure 5 and Figure 6 The first pad 5 and the second pad 30 mentioned above are used to protect the surfaces that come into contact with the patient, thus avoiding injury to the patient's body.

[0046] In this invention, a third mounting hole is provided at the middle position of each of the two partition discs 16, and a connecting shaft 21 is rotatably connected to the inner wall of the third mounting hole via a sealed bearing. The bottom end of the connecting shaft 21 is fixedly connected to the driving end of the driver 15, and a plurality of crushing blades 17 are mounted on the top end of the connecting shaft 21. The crushing blades 17 are located at the bottom of the storage chamber 41, such as... Figure 2 , Figure 3 , Figure 4 and Figure 11 By using the aforementioned connecting shaft 21 and crushing blade 17, the connecting shaft 21 and crushing blade 17 can be driven to rotate when the driver 15 is working. The crushing blade 17 crushes the waste material entering the storage chamber 41, reducing the volume of the waste material and facilitating its subsequent discharge.

[0047] In this invention, a device housing 8 is installed at the top of the outer casing 1, and a battery 19 and a controller 18 are installed inside the device housing 8. Multiple heat dissipation grooves 7 are provided on one side of the device housing 8, the side of the outer casing 1 near the driver 15, and the side of the outer casing 1 near the ultrasonic generator 1204. A handle pad 6 is installed on the outer wall of the outer casing 1. Figure 1 As shown, the heat dissipation slot 7 described above can dissipate the heat generated during equipment operation in a timely manner, ensuring the normal operating temperature of components such as battery 19 and controller 18, and extending the service life of the equipment.

[0048] In this invention, a first through hole 42 is provided on the top of one side of the storage chamber 41, and a second through hole 43 is provided on the top of one side of the liquid storage chamber 40. A sealing head 20 is attached to one side of both the first through hole 42 and the second through hole 43. A connecting frame 35 extending from the first through hole 42 and the second through hole 43 is fixed to one end of the sealing head 20. A pressing plate 9 is installed at the end of the connecting frame 35. Two rows of equidistant elastic telescopic rods 34 and corrugated protective tubes 10 are installed on one side of the outer wall of the pressing plate 9 and the outer wall of the outer shell 1. The corrugated protective tubes 10 are sleeved on the elastic telescopic rods 34. A control switch 33 is installed on the outer wall of the outer shell 1 near the bottom of the pressing plate 9. The control switch 33 is activated by the pressing plate 9. The control switch 33, controller 18, battery 19, ultrasonic generator 1204, and driver 15 are electrically connected. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 , Figure 10 and Figure 12 As shown, the pressing plate 9, elastic telescopic rod 34 and corrugated protective tube 10 described above can be used to operate the control switch 33 to start, and can also open the first through hole 42 and the second through hole 43 to facilitate the discharge of residual liquid and waste.

[0049] In summary, the working principle of this invention is as follows: First, hold or pinch the pressing plate 9 with one hand to disengage the sealing head 20 from the second through hole 43, and inject the debridement fluid into the reservoir 40 through the second through hole 43;

[0050] During operation, hold the entire instrument with one hand, ensuring the protective cover 4 and the first pad 5 cover the wound. Use the omnidirectional ball 2 to adjust the angle of the instrument, aligning the nozzle assembly 12 with the wound cleaning area. Then, firmly squeeze the pressure plate 9 to open the first through hole 42 and the second through hole 43, and press the entire instrument to its height, gradually bringing the nozzle assembly 12 and suction tube 26 closer to the wound cleaning area. Activate the pressure control switch 33 while the pressure plate 9 is in motion. The controller 18 drives the driver 15 and the ultrasonic generator 1204. The driver 15 drives the second drive shaft 27 and its auger blades 23 to rotate forward, which, in conjunction with the meshing of the gear 44, drives the first drive shaft 22 and its auger blades 23 to rotate in reverse, thus... Under the action of the auger blades 23 inside the drain cylinder 14, the debridement fluid in the storage chamber 40 is sprayed at high speed along the drain pipe 24 into the nozzle 1201. The cavitation effect of the ultrasonic waves in the ultrasonic generator 1204 is used to convert the debridement fluid into microbubbles. When the bubbles come into contact with the wound, they burst and generate a strong impact force, which can remove dirt, necrotic tissue and bacteria from the wound surface. At the same time, the auger blades 23 inside the suction cylinder 13 create a negative pressure, which allows the debridement waste fluid and foreign objects to enter the storage chamber 41 along the discharge pipe 28 for storage. Under the operation of the driver 15, the connecting shaft 21 and the pulverizer 17 are rotated. The pulverizer 17 pulverizes the waste entering the storage chamber 41, reducing the volume of the waste and facilitating subsequent discharge.

[0051] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
