The gun barrel includes a straight gun barrel and a bent gun barrel. The handle assembly of the integrated medical spray gun includes a switch, a pusher, a mounting seat, a handle, a spring, a mechanical valve, a pneumatic joint, an air outlet pipe, and an air inlet pipe.

[0005] The air guide joint of the integrated medical spray gun is installed with sealing ring 1, and after the tail end is installed with silicone tube 2, it is inserted into the gun rack connection. The water guide joint of the integrated medical spray gun is installed with silicone tube 1, silicone tube 1 is inserted into the medicine bottle, and the water guide joint is inserted into the gun rack connection. Preferably, the rubber Y-shaped ring is pressed and sealed through the spray gun head socket.

[0006] The front end of the gun barrel of the integrated medical spray gun is installed with a spray head. Preferably, the spray head is inserted into sealing ring 4 and pressed to seal. The knob of the gun barrel adopts a knurled design to enhance its anti-slip property. The tail end of the gun barrel is installed with sealing ring 3. After the gun barrel is installed, it is inserted into the water guide joint and fixed by rotating the limiting block into the card slot. Preferably, sealing ring 5 is installed and pressed to seal. More preferably, the gun rack connection is integrally formed to prevent the leakage of the liquid medicine due to the internal pressure and avoid affecting the spraying effect. The gun rack connection is preferably made of medical stainless steel or plastic by integral molding.

[0007] For the integrated medical spray gun described above, the gun holder is connected to the required medicine bottle through a screw groove. Preferably, a sealing ring limiting boss structure is designed at the connection of the lower end and the medicine bottle to fix the sealing ring 5 from the inner circle and prevent the sealing ring 5 from falling off after the medicine bottle is unscrewed. Preferably, two sealing rings 2 are installed at the tail end of the gun holder connection for double-layer sealing to enhance the sealing stability. After installation, the whole is inserted into the installation seat.

[0008] For the integrated medical spray gun described above, preferably, the straight barrel or the bent barrel is inserted into the card slot of the gun holder connection, and the rotating barrel limiting block is snapped into the card slot for fixation.

[0009] When the pusher of the integrated medical spray gun is pushed forward, the required gun body can be replaced. When the button is released, the hook of the replacement button will hook the square convex block of the gun body, and the square convex block restricts the rotation and movement of the gun holder connection pipe for better fixation.

[0010] The switch of the integrated medical spray gun is arranged at the bend of the gun body. By pressing it, the contact of the mechanical valve is touched, and it shares the same internal fixed point of the handle with the replacement pusher. One end of the spring is connected to the pusher, and the other end is connected to the internal fixed point of the handle. One end of the air outlet pipe is connected to the installation seat, and the other end is connected to the mechanical valve. The air inlet pipe is connected to the pneumatic joint of the mechanical valve and extends to the outside of the handle to connect to an external air source.

[0011] The beneficial technical effects achieved by the present utility model: The integrated medical spray gun provided by the present utility model adopts a rotating medical structure when installing the barrel, which is convenient for quickly replacing different types of barrels, saving the time for replacing the barrel. In addition, the gun holder is integrally molded by die-casting, optimizing the structure of the traditional spray gun and making the performance of the spray gun more stable.
