Description

Technical Field

[0001] This invention belongs to the field of medical device disinfection technology, specifically a disinfection device for controlling nosocomial infections. Background Technology

[0002] Disinfection refers to methods that kill pathogenic microorganisms, but not necessarily bacterial spores. It uses physical or chemical methods to eliminate pathogens that remain on different transmission media, thereby cutting off transmission routes, preventing and controlling the occurrence of infection, and avoiding possible cross-infection between surgical instruments and patients. Therefore, disinfection is particularly important in controlling nosocomial infections. Currently, medical instruments used in nosocomial surgeries include surgical knives, surgical scissors, surgical forceps, hemostats, needle holders, tissue forceps, retractors, gastric forceps, and other surgical tools.

[0003] In existing technologies, these used instruments are usually placed in specific sterilization equipment for disinfection and sterilization. However, the process is generally carried out using static methods, which makes it difficult to disinfect the connecting parts of the surgical instruments, such as crevices and hinges. As a result, the aforementioned disinfection methods require a long time to achieve complete disinfection, and such disinfection methods cannot improve efficiency. Summary of the Invention

[0004] To address the problems mentioned in the background section, the present invention provides a disinfection device for controlling nosocomial infections.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a disinfection device for controlling nosocomial infections, comprising a disinfection cabinet with a hinged door at the top. The disinfection cabinet contains an instrument disinfection section, which includes two hooks fixedly connected to the inner wall of one end of the disinfection cabinet. Gastric forceps are attached to the rods of both hooks. A motor is fixedly connected to the outer wall of one end of the disinfection cabinet, and a rotating rod is fixedly connected to the motor shaft. The rotating rod is movably sleeved onto one end of the disinfection cabinet. Specifically, the rotating rod also has two meshing gear discs, which are fixedly connected to one end of the rotating rod. A protective plate is movably sleeved onto the rotating rod, and the protective plate is fitted outside the gear discs. The two gear discs have a reciprocating structure for opening and closing the gastric forceps, and each gear disc also has a squeezing and rinsing structure.

[0006] Preferably, each of the two reciprocating structures includes a rocker arm fixedly connected to the gear disk. One side of the rocker arm is movably connected to the protective plate, and the other side of the rocker arm is slidably connected to a T-shaped rectangular groove plate one and a T-shaped rectangular groove plate two. Limiting groove plates are slidably connected to the plates of both the T-shaped rectangular groove plate one and the T-shaped rectangular groove plate two.

[0007] Preferably, one end of each of the two limiting slot plates is fixedly connected to the inner walls of both ends of the disinfection chamber, and a guide rod is fixedly connected to the outer wall of one end of the gear disk below, and the guide rod is movably connected to the inner wall of one end of the disinfection chamber.

[0008] Preferably, a frame plate is fixedly connected to both outer walls of the bottom end of the T-shaped rectangular groove plate, and an arc-angle U-shaped plate is fixedly connected to one side wall of each of the two frame plates. The inner wall of each arc-angle U-shaped plate can be fitted and connected to the two gastric forceps rods respectively.

[0009] Preferably, the squeezing and rinsing structure includes a short rectangular plate fixedly connected to one end of the T-shaped rectangular groove plate. Corrugated pipes are fixedly connected to the outer walls of both ends of the short rectangular plate, and long rectangular plates are fixedly connected to the other ends of the two corrugated pipes. One end of each of the two long rectangular plates is fixedly connected to the inner wall of one end of the disinfection chamber.

[0010] Preferably, the T-shaped rectangular groove plate II and the long rectangular plate are connected in a through sliding connection, and each of the two corrugated pipes has a liquid inlet pipe fixedly connected to its adjacent sidewall, and each of the two liquid inlet pipes has a one-way valve fixedly connected to its pipe body.

[0011] Preferably, each of the two rectangular plates has a liquid outlet pipe fixedly connected through to its side wall, and each of the two liquid outlet pipes has a one-way valve fixedly connected to its body. The other end of each of the two liquid outlet pipes has a perforated plate fixedly connected through to its body.

[0012] Preferably, two springs are fixedly connected to the outer walls on both sides of the other end of each of the slotted plates, and a connecting plate is fixedly connected to the other end of each set of springs.

[0013] Preferably, a brush plate is fixedly connected to one end of the outer wall of each set of connecting plates, and the bristles of each set of brush plates can intermittently slide and adhere to the inner walls of the upper and lower ends of the two gastric forceps.

[0014] Preferably, each of the arc-angle U-shaped plates is made of natural rubber.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] This invention activates a motor installed on the sterilization chamber, causing it to rotate a rotating rod. This, in turn, drives two gear discs to rotate in a mutual transmission, which in turn drives corresponding rocker arms to rotate synchronously. The rotating rocker arms slide within the T-shaped rectangular groove plate one and T-shaped rectangular groove plate two, thereby causing both plates to move back and forth vertically and horizontally along their respective groove walls. This also causes the connected frame plate and the arc-angle U-shaped plate to move vertically, thereby causing the clamped gastric forceps to expand and merge in opposite directions. This allows for better and faster cleaning and sterilization of the crevices and hinges of the gastric forceps that are difficult to sterilize.

[0017] When the T-shaped rectangular groove plate is passively moved laterally in this invention, it will drive the short rectangular plate to move synchronously, causing the two corrugated pipes to extend and retract respectively. This allows the disinfectant water in the disinfection chamber to be drawn in through the installed liquid inlet pipe. Then, during the reciprocating squeezing process, the squeezing impact force causes the water to be sprayed out from the perforated groove plate and sprayed onto multiple connection points in the center of the gastric forceps. It also causes the brush plate to contact the open biting part of the gastric forceps and clean it. Attached Figure Description

[0028] 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.

[0029] like Figures 1 to 7 As shown, the present invention provides a disinfection device for controlling nosocomial infections, including a disinfection housing 1, with a hinged door 11 at the top of the disinfection housing 1. The disinfection housing 1 is provided with an instrument disinfection section 2, which includes two hooks 21 fixedly connected to the inner wall of one end of the disinfection housing 1. Gastric forceps 22 are attached to the rods of the two hooks 21. A motor 23 is fixedly connected to the outer wall of one end of the disinfection housing 1. A rotating rod 24 is fixedly connected to the shaft of the motor 23. The rod of the rotating rod 24 is movably sleeved with one end of the disinfection housing 1. The rod of the rotating rod 24 is also provided with two meshing gear discs 25. The gear discs 25 are fixedly connected to one end of the rod of the rotating rod 24. A protective plate is movably sleeved on the rod of the rotating rod 24 and is sleeved outside the gear discs 25. The two gear discs 25 are provided with a reciprocating structure for opening and closing the gastric forceps 22. Both gear discs 25 are also provided with a squeezing and rinsing structure.

[0030] The above solution involves opening the door 11 of the sterilizer housing 1, hanging the gastric forceps 22 sequentially on the hooks 21, and then fitting the handle of the forceps into the corresponding U-shaped plate 231 for overall positioning. The door 11 is then closed, and the motor 23 installed on the sterilizer housing 1 is started, causing the rotating rod 24 to rotate. This, in turn, drives the two gear discs 25 to rotate, which in turn drives the corresponding rocker arm 26 to rotate synchronously. The rotating rocker arm 26 slides within the T-shaped rectangular groove 27 and the second T-shaped rectangular groove 28, thus causing both to move back and forth vertically and horizontally along their respective groove walls. This also drives the connected frame plate 230 and the U-shaped plate 231 to move forward. The vertical movement of the plate causes the clamping forceps 22 to expand and merge in opposite directions, thus enabling better and faster cleaning and disinfection of the crevices and hinges of the forceps 22, which are difficult to disinfect. When the T-shaped rectangular groove plate 28 passively moves horizontally, it drives the short rectangular plate 232 to move synchronously, causing the two corrugated pipes 234 to extend and retract respectively. This allows the disinfectant water in the disinfection chamber 1 to be drawn through the installed liquid inlet pipe 235. Then, during the reciprocating squeezing process, the squeezing impact force causes the water to be sprayed out from the perforated groove plate 239, spraying onto multiple connection points in the center of the forceps 22, and causing the brush plate 242 to contact the opening clamping parts of the forceps 22 for cleaning.

[0031] Both reciprocating structures include a rocker arm 26 fixedly connected to the gear disk 25. One side of the rocker arm 26 is movably connected to the protective plate, and the other side of the rocker arm 26 is slidably connected to a T-shaped rectangular groove plate 27 and a T-shaped rectangular groove plate 28. Limiting groove plates 29 are slidably connected to both the T-shaped rectangular groove plate 27 and the T-shaped rectangular groove plate 28. One end of each limiting groove plate 29 is fixedly connected to the inner walls of both ends of the sterilization chamber 1. Next, a guide rod is fixedly connected to one end of the outer wall of the lower gear disk 25. The guide rod is movably connected to one end of the inner wall of the sterilization box 1. A frame plate 230 is fixedly connected to both sides of the bottom end of the T-shaped rectangular groove plate 27. An arc-angle U-shaped plate 231 is fixedly connected to one end of the side wall of each of the two frame plates 230. Each arc-angle U-shaped plate 231 is made of natural rubber. The inner wall of each arc-angle U-shaped plate 231 can be fitted and connected to the two gastric forceps 22 rods respectively.

[0032] Using the above scheme: By starting the motor 23 installed on the disinfection machine box 1, it drives the rotating rod 24 to rotate, thereby driving the two gear disks 25 to rotate in mutual transmission. When the gear disk 25 is directly driven to rotate clockwise, the meshed lower gear disk 25 will rotate in the opposite direction, thereby driving the corresponding rocker arm 26 to rotate synchronously. The rotating rocker arm 26 will slide within the T-shaped rectangular groove plate 1 27 and T-shaped rectangular groove plate 28, thereby driving both to move back and forth vertically and horizontally along the path of their own groove walls. The passive reciprocating movement of both is guided horizontally by the limiting slot plate 29 connected and installed on the sterilization box 1. It is worth noting that when the T-shaped rectangular slot plate 27 moves up and down, it will simultaneously drive the connected frame plate 230 and the arc-angle U-shaped plate 231 to move up and down, thereby driving the clamping gastric forceps 22 to expand and merge in the opposite direction, thus realizing the path movement of the gastric forceps 22 when working, so as to better and faster clean and disinfect the gaps and hinges of the gastric forceps 22 that are not easy to be disinfected, and change it from a static state to an active state.

[0033] The squeezing and rinsing structure includes a short rectangular plate 232 fixedly connected to one end of the T-shaped rectangular groove plate 28. Corrugated pipes 234 are fixedly connected to the outer walls of both ends of the short rectangular plate 232, and long rectangular plates 233 are fixedly connected to the other ends of the two corrugated pipes 234. One end of each of the two long rectangular plates 233 is fixedly connected to the inner wall of one end of the sterilization chamber 1. The T-shaped rectangular groove plate 28 and one long rectangular plate 233 are connected through... Through sliding connection, inlet pipes 235 are fixedly connected to the adjacent side walls of the two corrugated pipes 234, and one-way valve 236 is fixedly connected to the pipe body of the two inlet pipes 235. Outlet pipes 237 are fixedly connected to the side walls of the two long rectangular plates 233, and one-way valve 238 is fixedly connected to the pipe body of the two outlet pipes 237. A perforated plate 239 is fixedly connected to the other end of the pipe body of the two outlet pipes 237.

[0034] Using the above scheme: When the T-shaped rectangular groove plate 28 passively moves horizontally, it will drive the short rectangular plate 232 to move synchronously, causing the corrugated pipes 234 at both ends to extend and contract respectively under the limit of the corresponding long rectangular plate 233. This allows the disinfectant water in the disinfection chamber 1 to be drawn through the installed liquid inlet pipe 235. Then, during the reciprocating squeezing process, the water is input into the liquid outlet pipes 237 installed on the two long rectangular plates 233. Immediately afterwards, the water is sprayed out from the perforated groove plate 239 by the squeezing impact force and sprayed onto the multiple connection points in the center of the gastric forceps 22, so as to achieve a better and faster cleaning effect, which complements the cleaning effect achieved by opening the gastric forceps 22 mentioned above.

[0035] Two springs 240 are fixedly connected to the outer walls on both sides of the other end of each slot plate 239. A connecting plate 241 is fixedly connected to the other end of each set of springs 240. A brush plate 242 is fixedly connected to the outer wall of one end of each set of connecting plates 241. The bristles of each set of brush plates 242 can intermittently slide and adhere to the inner walls of the upper and lower ends of the two gastric forceps 22.

[0036] Using the above solution: the sprayed water will cause the connecting plate 241 and the brush plate 242 connected by the spring to move horizontally, thereby causing the brush plate 242 to contact the biting part of the open stomach forceps 22 and clean it, thus achieving a better cleaning effect.

[0037] One point that needs to be added is: such as Figure 5 As shown, only the upper rocker arm 26 has a T-shaped rectangular groove plate 28 and a corresponding limiting groove plate 29.

[0038] The working principle and usage process of this invention are as follows: Open the door 11 of the sterilizer housing 1, hang the gastric forceps 22 sequentially on the hooks 21, and then fit the handle of the forceps into the corresponding U-shaped plate 231 for overall positioning. Afterwards, close the door 11, start the motor 23 installed on the sterilizer housing 1, causing it to drive the rotating rod 24 to rotate, thereby driving the two gear discs 25 to rotate in mutual transmission. This, in turn, drives the corresponding rocker arm 26 to rotate synchronously. The rotating rocker arm 26 will rotate within the T-shaped rectangular groove plate 27 and the T-shaped rectangular groove... The plate 28 slides within the limit, thereby driving both of them to move up and down and left and right along the path of their own groove walls. During the passive reciprocating movement of the two, the limit groove plate 29 connected and installed on the sterilization box 1 will guide them horizontally. It is worth noting that when the T-shaped rectangular groove plate 27 moves up and down, it will simultaneously drive the connected frame plate 230 and the arc-angle U-shaped plate 231 to move up and down, thereby driving the clamping gastric forceps 22 to expand and merge in the opposite direction, thus realizing the path movement of the gastric forceps 22 when it is working.

[0039] Meanwhile, when the T-shaped rectangular groove plate 28 passively moves horizontally, it drives the short rectangular plate 232 to move synchronously. This causes the corrugated pipes 234 at both ends to extend and contract respectively under the limit of the corresponding long rectangular plate 233. This allows the disinfectant water in the disinfection chamber 1 to be drawn in through the installed liquid inlet pipe 235. Then, during the reciprocating squeezing process, the water is input into the liquid outlet pipes 237 installed on the two long rectangular plates 233. Immediately afterward, the water is sprayed out from the perforated groove plate 239 by the squeezing impact force, spraying onto multiple connection points in the center of the gastric forceps 22. The sprayed water also drives the connecting plate 241 and the brush plate 242 connected by the spring to move horizontally. This causes the brush plate 242 to contact the opening biting part of the gastric forceps 22 and clean it, thus achieving a better cleaning effect.
