Description

Technical Field

[0001] This utility model relates to the field of medical flushing gun technology, and in particular to a medical flushing gun with adjustable pressure. Background Technology

[0002] In modern healthcare systems, it is necessary to rinse and disinfect patients' external trauma and surgical wounds. Compared to manually rinsing and wiping with cotton balls and gauze, medical rinsing guns can cover a larger wound area in a short time, greatly shortening the rinsing operation time and significantly improving efficiency. Doctors can rely on medical rinsing guns to customize rinsing plans for different patients based on the depth, area, and degree of infection of the wound, effectively removing dirt and bacteria, promoting wound healing from the depths, reducing the risk of infection recurrence, and improving the targetedness and effectiveness of treatment.

[0003] Traditional medical irrigation guns suffer from several drawbacks. They lack pressure regulation and are ill-suited for wounds of varying depths and complexities. For deeper wounds, the fixed low pressure prevents the irrigation fluid from penetrating to the bottom, leaving dirt, blood clots, and bacteria deep within the wound unremoved. This negatively impacts the wound healing environment and increases the risk of infection. Furthermore, if the flow rate is too low, the solution cannot evenly cover the wound, creating disinfection blind spots. Conversely, if the flow rate is too high, the fluid rushes across the wound too quickly, reducing the contact time between the solution and the wound and failing to guarantee sufficient sterilization duration, thus increasing the potential risk of wound infection. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an adjustable pressure medical irrigation gun, which aims to improve the problems in the prior art where the lack of pressure adjustment function and uncontrollable water flow lead to an impact on the wound healing environment and an increased risk of infection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable pressure medical flushing gun, comprising a hollow tube and a hollow barrel, wherein a pressure receiver is provided inside the hollow tube, a sealing plate is provided on the left side of the pressure receiver, a connecting plate is provided on the left side of the sealing plate, a threaded rod is threadedly connected to the left side of the connecting plate, a pressure gauge is provided on the left side of the outer wall of the hollow tube, a pressure pipe is connected to the right side of the pressure receiver, a connecting pipe is connected to the other end of the pressure pipe, a water pipe is connected to the right side of the pressure receiver, a manifold is connected to the right end of the pressure pipe, and an adjusting device is provided on the right side of the hollow barrel, the adjusting device being used to adjust the water flow.

[0006] As a further description of the above technical solution:

[0007] The adjusting device includes a fixing plate, a card on the right side of the fixing plate, a rotating handle rotatably connected to the right side of the card, a flow tank on the right side of the rotating handle, a plurality of guide pipes I connected to the right side of the flow tank, a plurality of guide pipes II connected to the right side of each of the plurality of guide pipes I, a baffle on the right side of each of the plurality of guide pipes II, a plurality of water outlet grooves opened on the right side of the baffle, and the right ends of each of the plurality of guide pipes II passing through the plurality of water outlet grooves, a splash-proof barrel I on the outer wall of the flow tank, and a splash-proof barrel II inside the splash-proof barrel I.

[0008] As a further description of the above technical solution:

[0009] A fixed handle is threaded to the top left side of the hollow barrel, and two hanging holes are opened on the front and back sides of the fixed handle.

[0010] As a further description of the above technical solution:

[0011] The hollow barrel has multiple threaded holes on the top left side, and multiple screws are threaded into the interior of each of the multiple threaded holes.

[0012] As a further description of the above technical solution:

[0013] The hollow barrel has a threaded hole two on its outer front side, and a threaded rod two is threadedly connected inside the threaded hole two.

[0014] As a further description of the above technical solution:

[0015] The threaded rod is provided with a rotating handle on the outside, and the hollow tube is provided with a hand grip at the bottom.

[0016] As a further description of the above technical solution:

[0017] A screw hole is provided on the top left side of the hand grip, and a screw is threaded into the screw hole.

[0018] As a further description of the above technical solution:

[0019] The right side of the grip is threaded with a handle pad, and the handle pad has multiple grooves on its upper and lower outer sides.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the threaded rod is connected to the connecting plate by a thread, which enables convenient pressure adjustment. Medical staff can make precise fine adjustments to the pressure according to the specific needs of the wound and by monitoring the pressure gauge in real time. The threaded adjustment can more accurately reach the required pressure value and adjust the pressure to a suitable value that allows the rinsing fluid to penetrate deep into the bottom of the wound, ensuring thorough removal of dirt and bacteria, thereby reducing the risk of infection recurrence and improving the pertinence and effectiveness of treatment.

[0022] 2. In this utility model, by rotating the handle and the card, medical staff only need to rotate the handle to drive the flow tank to move. The rotation of the flow tank changes the relative position with the guide tube, adjusts the flow rate of the rinsing fluid, meets the rinsing water flow requirements of different wounds, allows the rinsing fluid to better contact the wound, fully exerts the cleaning and disinfection effects, improves the rinsing effect, and thus ensures sufficient bactericidal action time, reducing the potential risk of wound infection.

A connecting plate 6 is located on the left side of the sealing plate 7, connecting the sealing plate 7 to the threaded rod 5 and transmitting the force of the threaded rod 5. The threaded rod 5 is threadedly connected to the left side of the connecting plate 6. By rotating the threaded rod 5, the connecting plate 6 and the sealing plate 7 can be pushed, thereby regulating the pressure inside the pressure receiver 8. A pressure gauge 4 is located on the left side of the outer wall of the hollow tube 1, which displays the pressure of the hollow tube 1 in real time. The internal pressure readings allow medical staff to easily understand the current pressure status. A pressure pipe 9 is connected to the right side of the pressure receiver 8. The pressure pipe 9 is responsible for transmitting the pressure adjusted by the pressure receiver 8 to subsequent components. The other end of the pressure pipe 9 is connected to a connecting pipe 10, which further directs the pressure and water flow to other parts. A water pipe 11 is connected to the right side of the pressure receiver 8. The water pipe 11 is used to introduce flushing water and provide a water source for flushing. A manifold 12 is connected to the right end of the pressure pipe 9. The manifold 12 can collect the water flow transmitted from the pressure pipe 9.
