Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an anti-splash device for a pulse washer. Background Art

[0002] Pulse irrigation has a pressurization period and a decompression period between each pulse, which causes the tissue being irrigated to contract and relax at different times, accelerating the loosening of foreign bodies between tissues, and then causing foreign bodies, bacteria, debris and hematomas lurking in the tissues to detach from the tissue surface due to vibration and be washed away by the irrigation fluid, thus achieving the purpose of thorough debridement. In view of the significant advantages of pulse irrigation in clinical practice, its application in trauma, orthopedics, joints and other related departments is becoming increasingly widespread.

[0003] The splash guard of an orthopedic pulse irrigator is a device used to assist wound debridement and surgical site flushing in orthopedic surgery. The device is usually used in conjunction with a pulse irrigator, and is specifically designed to prevent the splashing of liquid generated during the flushing process, thereby protecting the occupational safety of surgical personnel and reducing the incidence of orthopedic type I incision infection. The design of the splash guard usually includes a protective cover or baffle to shield and guide the flushing liquid. This protective cover can be removable for easy cleaning and disinfection. At the same time, it can also be designed with adjustable angles and positions to meet the needs of different surgical sites. In addition, the splash guard of an orthopedic pulse irrigator can also be equipped with other auxiliary functions, such as a suction device or a filter, to further reduce the impact of splashed liquid on the surgical environment. These functions can be selected and configured according to specific needs and surgical requirements. In general, the splash guard of an orthopedic pulse irrigator is an important surgical auxiliary device that can improve the safety of surgery and reduce the impact of liquid splashing on surgical personnel and the surgical environment, thereby ensuring the success of the surgery and the safety of the patient.

[0004] The splash-proof device of the orthopedic pulse irrigator has not been widely used in the medical field. Its main purpose is to prevent splashing and splashing during the flushing process to protect the safety of medical staff and patients. However, the existing splash-proof device of the orthopedic pulse irrigator still has some shortcomings:

[0005] 1. Inadequate design: The existing splash-proof device is not well designed and cannot effectively prevent the flushing liquid from splashing, thereby increasing safety risks.

[0006] 2. Inconvenient operation: Some splash-proof devices are too complicated and not easy to operate. Medical staff need to spend more time and energy to operate the device, which affects work efficiency. Other splash-proof devices are too simple, and the liquid blocked by the splash-proof device may be splashed again, which reduces the actual efficiency of the device and fails to solve the theoretical problem well.

[0007] 3. Limited scope of application: The existing splash-proof device is only applicable to a specific type of orthopedic pulse irrigator, and is not applicable to other types of irrigators. This will limit the scope of use of the device, forcing some medical institutions to purchase different types of splash-proof devices to adapt to different irrigators.

[0008] The Chinese patent publication number is CN 213131210 U, and the publication date is May 7, 2021. The patent "A New Type of Flushing Nozzle" discloses a new type of flushing nozzle, including an inner tube, an outer tube, a nozzle and a splash shield. The inner tube is arranged on the inner side of the outer tube, and the front end of the inner tube and the nozzle connection end are connected to a liquid inlet pipe, and the front end of the outer tube and the splash shield connection end are connected to a liquid discharge pipe. The splash shield is provided with a pressure relief hole, and a second splash shield is also provided on the outside of the splash shield. The second splash shield is sleeved on the outer tube. Although the structure is provided with a second splash shield, the liquid will flow to the wound along the second splash shield, and the liquid cannot be effectively recovered.

[0009] Therefore, it is necessary to design a new splash-proof device to solve the above-mentioned problems of the prior art. Utility Model Content

[0010] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a splash-proof device for a pulse irrigator. Through various structural improvements and designs, when a pulse irrigator is used to irrigate a wound, it can prevent liquid splashing and recover liquid, and the device can be reused multiple times to reduce costs.

[0011] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0012] A splash-proof device for a pulse flusher comprises a cover body, characterized in that: the cover body comprises a hemispherical outer cover and an inner cover which are mutually nested in the outer and inner layers; the cover surface of the outer cover is spherical, and a first through hole for preventing backflow into the pulse flusher is provided at the top of the arc-shaped cover surface, and an elastic first sealing valve is fixedly provided in the first through hole, and a suction port is provided near the edge at the bottom end of the arc-shaped cover surface of the outer cover; the cover surface of the outer cover is hemispherical, and a second through hole for preventing backflow into the pulse flusher is provided at the top of the cover surface of the inner cover, and an elastic second sealing valve is fixedly provided in the second through hole, the cover surface of the inner cover is spherical, and a liquid suction hole is provided on the cover surface of the inner cover, and the liquid suction hole is trumpet-shaped with a small outside and a large inside, and the lower edge of the cover surface of the inner cover extends horizontally outward to form a horizontal edge of the inner cover.

[0013] Due to the adoption of the above new design scheme, the splash-proof device of the pulse washer provided by the utility model has the following beneficial effects:

[0014] 1. Highly efficient splash prevention: By setting a trumpet-shaped liquid suction hole on the cover surface of the inner cover, under the action of negative pressure, the flushing liquid can be sucked into the gap between the inner cover and the outer cover in a timely manner, and then flow from the suction port to the external liquid collection tank, so that it can still effectively prevent the flushing liquid from splashing again under high-pressure flushing, thereby protecting the surgical environment and the safety of the surgical team.

[0015] 2. Easy to operate and reusable: The edge of the inner cover and the lower edge of the outer cover are designed to be detachably connected, so that the inner cover and the outer cover can be disassembled, cleaned and disinfected after use, and can be reused, saving costs and simplifying the installation and adjustment steps of the splash-proof device, so that it can quickly and easily adapt to different surgical needs and reduce surgical risks.

[0016] 3. Strong adaptability: By designing an elastic and movable valve opening, it can be used at multiple angles to solve the problem of different depths of angles in different parts and improve the flexibility and efficiency of the operation.

[0017] 4. Visual operation: It uses transparent material with a trumpet-shaped suction hole to meet the doctor's visual operation requirements, does not affect the surgical process, and improves the doctor's acceptance. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Example

[0033] See also Figure 1-12The splash-proof device of the pulse flusher provided by the embodiment of the utility model is a targeted improvement design applied to the needs of surgical departments in hospitals, etc., and comprises an outer transparent cover body 1, which comprises an outer and inner hemispherical outer cover 2 and an inner cover 3 which are mutually nested and concentric; the cover surface of the outer cover 2 is spherical, and a first through hole 4 for preventing backflow of the pulse flusher is provided at the top of the arc-shaped cover surface, and an elastic first sealing valve 5 is fixedly provided in the first through hole 4, and a suction port 6 is provided at the bottom end of the arc-shaped cover surface of the outer cover 2 near the edge; the cover surface of the outer cover 2 is hemispherical, and a second through hole 7 for preventing backflow of the pulse flusher is provided at the top of the cover surface of the inner cover 3, and an elastic second sealing valve 8 is fixedly provided in the second through hole 7 The cover surface of the inner cover 3 is spherical, and a liquid suction hole 9 is arranged on the cover surface of the inner cover 3. The liquid suction hole 9 is small outside and large inside and is in the shape of a trumpet. The lower edge of the cover surface of the inner cover 3 extends horizontally outward to form a horizontal edge 10 of the inner cover; the first through hole 4 and the second through hole 7 are concentric and have the same diameter; the horizontal edge 10 of the inner cover is detachably connected to the lower edge of the outer cover 2; in this embodiment, the diameters of the first sealing valve 5 and the second sealing valve 8 are both 45mm; the diameter of the suction port 6 is 8mm, and the suction port 6 is also movably connected to a drainage tube with negative pressure; the cover surfaces of the inner cover 3 and the outer cover 2 are parallel to each other to form a concentric circle structure, and a gap is left between the inner cover 3 and the outer cover 2, and the two cover surfaces do not contact each other.

[0034] The diameter of the outer cover 2 is designed to be larger than the diameter of the inner cover 3 , and the cover surface of the outer cover 2 completely covers the cover surface of the inner cover 3 inside.

[0035] The inner cover 3 and the outer cover 2 of the cover body 1 are both hemispherical components made of transparent PVC medical plastic, which is convenient for users to observe the situation.

[0036] The liquid suction holes 9 are multiple, evenly spaced and distributed on the cover surface of the inner cover 3 , and are trumpet-shaped through holes, with an inner hole diameter of 6 mm and an outer hole diameter of 3 mm, forming a through hole array.

[0037] In this embodiment, the arc diameter of the outer cover 2 is 120 mm, and the arc diameter of the inner cover 3 is 110 mm; a cavity with a distance of 10 mm is left between the outer cover 2 and the inner cover 3, so that the outer cover 2 and the inner cover 3 do not contact each other.

[0038] Specifically, the inner cover edge 10 is detachably connected to the lower edge of the outer cover 2, and the inner cover edge 10 and the lower edge of the outer cover 2 can be threaded or snap-connected, so that they can be disassembled, cleaned and disinfected after use, and can be reused. The first through hole 4 and the second through hole 7 are concentric and have the same diameter, so that the barrel of the pulse flusher can be directly inserted into the inner cover along the through hole to clean the wound. The inner cover 3 is concentric with the outer cover 2, and the diameter of the outer cover 2 is larger than that of the inner cover 3. The diameter of the outer cover 2 is 120mm, the diameter of the outer hole of the inner cover 3 is 110mm, and the diameter of the suction port 6 is 8mm. The suction port 6 is movably connected to the drainage tube with negative pressure, so that a parallel gap is formed between the inner cover 3 and the outer cover 2, thereby ensuring the stability of the negative pressure. At the same time, the splashed liquid can flow along the gap to the suction port 6 along the attraction of the negative pressure, and then flow to the drainage pipe liquid storage tank. The cover body 1 adopts transparent PVC The medical plastic is made of transparent material and does not hinder the doctor's sight, thus meeting the doctor's visual operation requirements and not affecting the operation process. The doctor's acceptance is improved. The first sealing valve 5 and the second sealing valve 8 have a diameter of 45 mm. Because the first and second sealing valves are elastic and are arranged on the first through hole 4 and the second through hole 7, when the pulse flusher barrel passes through the through hole, the valve can wrap the pulse flusher barrel well to prevent the splashing liquid from splashing through the gap between the barrel and the through hole. Moreover, the sealing valve has a diameter of 45 mm, which can be suitable for different types of pulse flusher barrels. The barrel can be used at multiple angles to solve the problem of different depths of angles in different parts and improve the flexibility and efficiency of the operation. The liquid suction holes 9 are trumpet-shaped through holes evenly distributed on the cover surface of the inner cover 3 with an inner hole diameter of 6 mm and an outer hole diameter of 3 mm, which can make the splashing liquid quickly sucked into the cavity between the inner cover 3 and the outer cover 2.

[0039] The working principle of the utility model is: before flushing, the sterilized outer cover 2 and the inner cover 3 are connected by threading or clamping, the pulse flusher gun barrel is passed through the through hole of the outer cover 2 and the inner cover 3 through the gap of the sealing valve, the drainage tube with negative pressure connected to the external liquid storage tank is connected to the suction port 6 of the outer cover 2, and then the pulse flushing is performed on the wound, and the external negative pressure device is started at the same time. When the liquid generated during the flushing process splashes, the splashed liquid is quickly sucked away from the suction hole 9 of the inner cover 3 by the attraction of the drainage tube, so as to prevent the flushing liquid from splashing out for the second time and avoid splashing on the medical staff, so as to protect the safety of the operating environment and the operating team. After flushing, the inner cover 3 and the outer cover 2 can be disassembled for cleaning and disinfection, and can be reused many times to save costs.

[0040] In summary, the utility model focuses on improving the safety of surgery and reducing the impact of liquid splashing on surgical personnel and the surgical environment through multi-faceted structural improvement designs, thereby ensuring the success of the surgery and the safety of the patient. It can be reused multiple times to save costs.
