Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to an infection-preventing flushing device for surgery. Background Art

[0002] During medical surgery, flushing is an important step in preventing and controlling infection. Whether it is dental surgery, gynecological surgery or surgical wound treatment, a large amount of flushing fluid is required to clean the surgical site, kill or remove potential pathogens, and reduce the risk of postoperative infection. However, although the importance of flushing in surgery is self-evident, existing surgical flushing devices have exposed a series of problems and limitations in actual applications.

[0003] Firstly, the structure of human internal organs is complex and fragile. When flushing the body directly, if the water flow from the nozzle is not properly controlled, it is very easy to cause damage to some fragile organs and blood vessels in the body. This damage may not only cause immediate complications such as bleeding and pain, but also affect the normal function of the organs and even have adverse effects on the long-term health of the patient. Secondly, in surgical wound flushing, the treatment of wastewater after flushing is also a thorny problem. Traditional flushing methods often make it difficult to effectively recycle wastewater, resulting in a large amount of wastewater accumulating in the operating room, which not only increases the workload of postoperative cleaning, but also may become a new source of pollution.

[0004] Therefore, it is necessary to propose an anti-infection flushing device for surgery to solve the above problems, improve the effect and safety of surgical flushing, and provide better medical services for patients. Summary of the invention

[0005] The present invention provides an infection prevention and flushing device for surgery. The arc-shaped end of an outer tube guides the device to aim at a wound, cleans the wound of a patient, and achieves an efficient flushing effect. At the same time, a vacuum pump is started to suck the air in an inner tube to form a negative pressure environment. The flow of the air in the inner tube drives the flow of sewage, so that the sewage is directly recovered during the flushing process, reducing the possibility of the sewage contacting other skin of the patient. When surgery is performed on the patient's body, the sewage in the wound will not flow to other places in the body, thereby causing pollution to other places, so as to solve the problems raised in the background technology.

[0006] The technical solution of the present invention is as follows:

[0007] An infection prevention and flushing device for surgery, comprising: a base, a water storage tank is arranged on the top of the base, a chamber 1 and a chamber 2 are arranged in the water storage tank respectively, a cleaning component is arranged in the chamber 1, a drain valve is arranged at the bottom of the chamber 1, a nozzle is arranged at the position of the chamber 1 on the top of the water storage tank, a vacuum switching valve is arranged on one side of the water storage tank, and a flushing component is arranged on the top of the vacuum switching valve;

[0008] The flushing assembly includes an outer tube and an inner tube fixedly connected to the water tank, one end of the outer tube is connected to the chamber 2, and the inner tube is connected to the chamber 1. A water pressure pump is provided at one end of the outer tube close to the water tank, and a vacuum pump is provided at one end of the inner tube close to the water tank. An end of the inner tube away from the water tank extends into the outer tube.

[0009] Furthermore, a slide groove 1 is provided at the bottom of the water tank, and a partition is slidably connected in the slide groove 1. The partition is between the chamber 1 and the chamber 2, and the space between the chamber 1 and the chamber 2 can be flexibly utilized, so that the space occupied by the device is smaller than that occupied by an ordinary device, but more saline solution can be held. A slide groove 2 is provided on the side of the partition close to the chamber 1.

[0010] Furthermore, sealing strips are provided at the contact points between the partition plate and the inner wall of the slide groove 1 and the water tank, thereby ensuring the sealing between the chamber 1 and the chamber 2.

[0011] Furthermore, the cleaning component includes a slider slidably connected in the second slide groove, a rotating rod is rotatably connected in the slider, the rotating rod passes through the slider, a motor is arranged on the top of the rotating rod, the output end of the motor is fixedly connected to the rotating rod, a gear is fixedly connected to the rotating rod, the gear is between the slider and the motor, the rotating rod is fixedly connected to a soft plate at the bottom of the slider, and the connection between the soft plate and the rotating rod is arc-shaped to prevent dirt accumulation.

[0012] Furthermore, the partition is fixedly connected with a latch tooth at a top position of the slide groove, and the latch tooth is provided with a plurality of latch teeth and is in the shape of a rack. The gear meshes with the latch teeth, and when the gear rotates, it slides on the plurality of latch teeth, so that the rotating rod can rotate.

[0013] Furthermore, one end of the outer tube away from the water tank is fixedly connected to a limiting block, and the inner tube passes through the limiting block and is fixedly connected to the limiting block.

[0014] Furthermore, the end of the outer tube away from the water tank is provided with an inward arc, and the end of the inner tube away from the water tank is 3 cm shorter than the outer tube. When the outer tube is aligned with the wound, the end of the inner tube will not scratch the wound.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention guides the wound with the arc at the end of the outer tube to clean the wound of the patient, thereby achieving an efficient flushing effect. At the same time, the vacuum pump is started to suck the air in the inner tube to form a negative pressure environment. The flow of air in the inner tube drives the flow of sewage, so that the sewage is directly recovered during the flushing process, reducing the possibility of sewage contacting other skin of the patient. When performing surgery on the patient's body, the sewage in the wound will not flow to other places in the body, thereby causing pollution to other places.

[0017] 2. The present invention ensures thorough cleaning of the inner wall of chamber one by scraping the inner wall of chamber one with a soft plate, removes stubborn stains that are difficult to remove with cleaning fluid, and when the rotating rod rotates, the gear is driven to rotate, the gear is engaged with the latching teeth, and drives the rotating rod and the slider to slide in the second slide groove, so that the bottom of the rotating rod cleans the bottom plate of chamber one. When the partition moves to the end of the first slide groove, the distance between the partition and the water tank is exactly the distance of a rotating rod plus half the soft plate. At this time, the rotating rod drives the soft plate to rotate to clean the inner wall of the end of the water tank, so that chamber one is completely cleaned. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] like Figure 1-Figure 5 As shown, the present invention provides an infection prevention and flushing device for surgery, comprising: a base 1, a water storage tank 2 is arranged on the top of the base 1, a chamber 3 and a chamber 2 4 are arranged in the water storage tank 2, a cleaning component 5 is arranged in the chamber 1 3, a drain valve is arranged at the bottom of the chamber 1 3, a nozzle is arranged at the position of the chamber 1 3 on the top of the water storage tank 2, a vacuum switching valve 6 is arranged on one side of the water storage tank 2, and a flushing component 7 is arranged on the top of the vacuum switching valve 6;

[0027] The flushing assembly 7 includes an outer tube 71 and an inner tube 72 fixedly connected to the water tank 2, one end of the outer tube 71 is connected to the chamber 2 4, and the inner tube 72 is connected to the chamber 1 3. A water pressure pump 73 is provided at the end of the outer tube 71 close to the water tank 2, and a vacuum pump 74 is provided at the end of the inner tube 72 close to the water tank 2. The end of the inner tube 72 away from the water tank 2 extends into the outer tube 71.

[0028] As a technical solution of the present invention, a chute 21 is provided at the bottom of the water tank 2, and a partition 22 is slidably connected in the chute 21. The partition 22 is between the chamber 1 3 and the chamber 2 4. The space between the chamber 1 3 and the chamber 2 4 can be flexibly utilized, so that the space occupied by this device is smaller than that occupied by an ordinary device, but more physiological saline can be loaded. A chute 23 is provided on the side of the partition 22 close to the chamber 1 3.

[0029] As a technical solution of the present invention, sealing strips 221 are provided at the contact points between the partition 22 and the chute 1 21 and the inner wall of the water tank 2 to ensure the sealing between the chamber 1 3 and the chamber 2 4 .

[0030] As a technical solution of the present invention, the cleaning component 5 includes a slider 51 slidably connected in the slide groove 23, a rotating rod 52 is rotatably connected in the slider 51, the rotating rod 52 passes through the slider 51, a motor 53 is arranged on the top of the rotating rod 52, the output end of the motor 53 is fixedly connected to the rotating rod 52, a gear 54 is fixedly connected to the rotating rod 52, the gear 54 is between the slider 51 and the motor 53, the rotating rod 52 is fixedly connected to a soft plate 55 at the bottom of the slider 51, and the connection between the soft plate 55 and the rotating rod 52 is arc-shaped to prevent dirt accumulation.

[0031] As a technical solution of the present invention, the partition 22 is fixedly connected with a latch tooth 541 at the top of the slide groove 21. The latch tooth 541 is provided with a plurality of latch teeth 541 and is in the shape of a rack. The gear 54 is meshed with the latch teeth 541. When the gear 54 rotates, it slides on the plurality of latch teeth 541, so that the rotating rod 52 can rotate.

[0032] As a technical solution of the present invention, the end of the outer tube 71 away from the water tank 2 is fixedly connected to the limiting block 711, and the inner tube 72 passes through the limiting block 711 and is fixedly connected to the limiting block 711 to prevent the inner tube 72 from being displaced when cleaning the patient's wound area.

[0033] As a technical solution of the present invention, the end of the outer tube 71 away from the water tank 2 is provided with an inward arc, and the end of the inner tube 72 away from the water tank is 3 cm shorter than the outer tube 71. When the outer tube 71 is aligned with the wound, the end of the inner tube 72 will not scratch the wound.

[0034] Working principle:

[0035] like Figure 1-Figure 2 and Figure 5As shown, first, the staff fills the chamber 2 4 with saline solution. During the filling process, the saline solution pushes the partition 22 to move toward the chamber 1 3, which can maximize the use of the space in the water storage tank 2 and store saline solution to the maximum extent, so as to facilitate the flushing of the surgical site during the operation and prevent insufficient saline solution during the operation, thereby affecting the progress of the operation. After the saline solution is filled, the system enters the air pressure balance stage. At this time, the staff starts the vacuum switching valve 6 to make the air pressure in the chamber 1 3 and the chamber 2 4 consistent, providing a stable air pressure environment for subsequent flushing operations, ensuring that the flushing liquid can be smoothly and stably sprayed from the chamber 2 4 through the outer tube 71 to the surgical site. At the same time, the air pressure balance also avoids problems such as unstable liquid injection or poor reflux caused by air pressure differences during the flushing process. When the surgical site needs to be cleaned, the staff accurately aligns the outer tube 71 with the wound, and then starts the water pressure pump 73 to pressurize the saline solution in the chamber 2 4 and spray it along the outer tube 71. When the saline solution reaches the end of the outer tube 71, it is sprayed by the outer tube 71. The arc at the end guides the wound to clean the patient's wound to achieve an efficient flushing effect. At the same time, the vacuum pump 74 is started to suck the air in the inner tube 72 to form a negative pressure environment. This negative pressure environment not only helps to suck the sewage after flushing into the inner tube 72, but also drives the flow of sewage through the flow of air in the inner tube 72, so that the sewage is directly recovered during the flushing process, reducing the possibility of sewage contacting other skin of the patient. When the patient's body is operated on, the sewage in the wound will not flow to other places in the body, thereby causing pollution to other places. Finally, the sewage is guided into the chamber 13. As the physiological saline in the chamber 24 is continuously discharged, the internal air pressure gradually decreases. Since the chamber 13 is not directly involved in the flushing process, its air pressure is relatively high. This air pressure difference prompts the partition 22 to slide in the slide groove 21 toward the chamber 13, providing a larger space for subsequent sewage recovery. As the partition 22 moves, the space of the chamber 13 gradually increases, providing a more spacious channel for the reflux of sewage, ensuring that the sewage can flow smoothly into the chamber 13.

[0036] like Figure 1-Figure 4As shown, then, when the cleaning is completed, the staff starts the drain valve in chamber 1 3 to drain the sewage in chamber 1 3, and then starts the nozzle on the top of the water storage tank 2 to spray clean water into chamber 1 3 to clean the environment in chamber 1 3, and then starts the motor 53 and the vacuum switching valve 6, so that a pressure difference occurs between chamber 1 3 and chamber 2 4, thereby causing the partition 22 to slide in the direction of chamber 1 3, and at the same time, the motor 53 drives the rotating rod 52 to rotate, and the rotating rod 52 drives the soft plate 55 to rotate, and the soft plate 55 scrapes against the inner wall of chamber 1 3, ensuring that the inner wall of chamber 3 is cleaned. The rotating rod 52 and the slider 51 are driven to slide in the second slide groove 23, so that the bottom of the rotating rod cleans the bottom plate of the chamber 3. When the partition 22 moves to the end of the slide groove 21, the distance between the partition 22 and the water tank 2 is exactly the distance of the rotating rod 52 plus half of the soft plate 55. At this time, the rotating rod 52 drives the soft plate 55 to rotate to clean the inner wall of the end of the water tank 2, so that the chamber 3 is completely cleaned.
