TECHNICAL FIELD

[0001] The present application belongs to the technical field of medicine applying device, and particularly relates to a burn dressing change sprayer. BACKGROUND

[0002] Burn generally refers to thermal damage to tissues caused by hot liquids (water, soup, oil, etc.), steam, high-temperature gas, flame, molten metal liquid or solid (such as molten steel, steel ingot) and the like, mainly referring to the skin, and in severe cases, subcutaneous or submucosal tissues such as muscles, bones, joints and even internal organs can also be damaged. When a person is burned, a series of professional treatments must be performed, and medicine must be applied and the affected area must be bandaged to avoid more serious consequences such as infection, inflammation or ulceration. Before applying ointment to a burn patient, the doctor will generally first spray pain-relieving spray on the patient to reduce the patient's pain when applying medicine. However, the above operation requires medical personnel to first spray pain-relieving spray using a spray bottle, then manually squeeze the ointment to the affected area, and finally use a cotton swab or a brush to evenly apply the ointment. That is, the entire process requires frequent replacement of medicines and tools, which is very troublesome.

[0021] By reciprocating the pressure rod 9, the piston 5 can be driven to reciprocate in the inflation cavity 4, so that the gas in the inflation cavity 4 is pressed into the liquid medicine storage tank 2 and the ointment storage tank 3 through the inflation main road 6 and the inflation branch road 7, thereby pressurizing the liquid medicine storage tank 2 and the ointment storage tank 3. When applying medicine, the outflow of pressurized ointment and pressurized liquid can be controlled by pressing the corresponding normally closed switch valve 18.

[0022] In this embodiment, the casing 1 is gun-shaped, and a handle is arranged at the bottom to facilitate medical staff to operate.

[0023] In this embodiment, the two first check valves 8 allow gas to pass from the side close to the inflation main road 6 to the side away from the inflation main road 6, that is, the gas can only enter the two storage tanks through the first check valves 8, but cannot flow out of the two storage tanks through the first check valves 8. The second check valve 10 allows gas to pass from the side close to the pressure rod 9 to the side away from the pressure rod 9, so that during the movement of the piston 5 to the right, gas can be filled into the left inflation cavity 4 through the second check valve 10.

[0024] In this embodiment, an air inlet hole 15 is formed in the side wall of the end of the inflation cavity 4 away from the inflation main road 6, so that the inflation cavity 4 on the right side of the piston 5 is in communication with the outside through the air inlet hole 15, thereby continuously supplementing air.

[0025] In the embodiment, the top of the shell 1 is respectively provided with a first mounting interface 16 and a second mounting interface 17, the inlet end of the first conveying pipe 13 and the gas outlet end of one of the gas supply branches 7 are arranged in the first mounting interface 16, the inlet end of the second conveying pipe 14 and the gas outlet end of the other gas supply branch 7 are arranged in the second mounting interface 17, the first mounting interface 16 and the second mounting interface 17 are respectively provided with internal threads, the tank opening of the liquid medicine storage tank 2 and the tank opening of the ointment storage tank 3 are respectively provided with external threads, the tank opening of the liquid medicine storage tank 2 is threadedly connected to the first mounting interface 16, and the tank opening of the ointment storage tank 3 is threadedly connected to the second mounting interface 17.

[0026] In the embodiment, the first mounting interface 16 is provided with a first sealing gasket between the tank opening end surface of the liquid medicine storage tank 2 and the bottom surface of the first mounting interface 16, and the second mounting interface 17 is provided with a second sealing gasket between the tank opening end surface of the ointment storage tank 3 and the bottom surface of the second mounting interface 17. The first sealing gasket and the second sealing gasket can ensure the connection sealing of the liquid medicine storage tank 2 and the connection sealing of the ointment storage tank 3, thereby preventing air leakage and medicine leakage.

[0027] In the embodiment, the normally closed on-off valve 18 includes a valve cavity arranged in the shell 1, the valve cavity is communicated with the corresponding conveying pipe on both sides, a valve core 181 is slidably arranged in the valve cavity, the valve core 181 is in sealing sliding connection with the side wall of the valve cavity, a liquid passing hole 182 is arranged through the valve core 181, a spring 183 is fixedly connected to one end of the valve core 181, and a button 184 is fixedly connected to the other end of the valve core 181. The button 184 extends to the outside of the shell through the through hole in the shell. By pressing the button 184, the valve core 181 can be pushed to move against the elastic force of the spring 183, so that the liquid passing hole 182 is aligned with the interfaces of the conveying pipes on both sides of the valve cavity, and the liquid medicine or ointment can be normally discharged through the conveying pipe.

[0028] In the embodiment, the button 184 of the normally closed on-off valve 18 communicated with the first conveying pipe 13 is located at the top of the shell 1, and the button 184 of the normally closed on-off valve 18 communicated with the second conveying pipe 14 is located at the bottom of the shell 1. The two buttons 184 are respectively arranged at the top and the bottom of the shell 1, which can avoid the situation that the medical staff presses the wrong button.

[0029] In the embodiment, the housing 1 is provided with a mounting groove between the atomizing nozzle 11 and the ointment outlet 12 away from one end of the pressing rod 9. A rotating shaft 19 is fixedly connected between the top wall and the bottom wall of the middle part of the mounting groove. A mounting seat 20 is rotatably connected to the rotating shaft 19. A brush rod 21 is detachably mounted on the mounting seat 20. One end of the brush rod 21 away from the mounting seat 20 is fixedly connected with a brush head 22. When the ointment needs to be evenly coated after the medicine is applied, the brush rod 21 can be rotated so that the brush head 22 faces the outside of the mounting groove, thereby facilitating the use of the brush head 22 to evenly coat the ointment. The brush rod 21 and the mounting seat 20 are detachably connected, thereby facilitating the disassembly and replacement after use.

[0030] In the embodiment, one end of the brush rod 21 is threadedly mounted in a threaded hole on the mounting seat 20. In other embodiments, the brush rod 21 and the mounting seat 20 can also be connected in a plug-in manner.
