Description

Technical Field

[0001] The invention belongs to the technical field of medicine applying instruments, and in particular relates to a burn dressing change sprayer. Background Art

[0002] Burns generally refer to tissue damage caused by heat, including hot liquids (water, soup, oil, etc.), steam, high-temperature gases, flames, hot metal liquids or solids (such as molten steel, steel ingots), etc., mainly to the skin. In severe cases, subcutaneous or submucosal tissues such as muscles, bones, joints, and even internal organs may also be damaged. When a burn is sustained, the human body must undergo a series of professional treatments, including applying medicine and bandaging the affected area to avoid more serious consequences such as infection, inflammation, or ulceration. Before applying ointment to burn patients, doctors usually spray them with pain-relieving spray to alleviate the pain of the patient when applying the ointment. However, the above operation requires medical staff to first spray the pain-relieving spray with a spray bottle, then manually squeeze the ointment onto the affected area, and finally apply the ointment evenly with a cotton swab or brush. That is, the entire process requires frequent replacement of medicines and tools, which is very troublesome. Therefore, it is urgent to design a burn dressing sprayer that can combine the functions of spraying pain-relieving spray and applying ointment. Summary of the Invention

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0020] Reference Figure 1-2A burn dressing sprayer includes a shell 1, a liquid medicine storage tank 2 and an ointment storage tank 3 are detachably mounted on the top of the shell 1, the liquid medicine storage tank 2 is used to hold analgesic liquid, and the ointment storage tank 3 is used to hold scald ointment, an air-filled chamber 4 is provided inside the shell 1, a piston 5 is slidably mounted in the air-filled chamber 4, one end of the air-filled chamber 4 is connected to an air-filled main path 6, and the end of the air-filled main path 6 away from the air-filled chamber 4 is connected to two air-filled branches 7, the air outlet ends of the two air-filled branches 7 extend into the liquid medicine storage tank 2 and the ointment storage tank 3 respectively, and the air outlet ends of the two air-filled branches 7 are both equipped with a first one-way valve 8, the piston 5 is fixedly connected to the end away from the main inflation path 6 with a pressure rod 9, and the end of the pressure rod 9 away from the piston 5 passes through the through hole on the side wall of the inflation chamber 4 and extends to the outside of the shell 1. An air inlet pipe connecting the inflation chambers on both sides is provided in the piston 5, and the air inlet pipe is connected to a second one-way valve 10. An atomizing nozzle 11 and an ointment outlet 12 are provided on the end of the shell 1 away from the pressure rod 9. The atomizing nozzle 11 is connected to the liquid medicine storage tank 2 through a first delivery pipe 13, and the ointment outlet 12 is connected to the ointment storage tank 3 through a second delivery pipe 14. Normally closed switch valves 18 are respectively provided on the first delivery pipe 13 and the second delivery pipe 14.

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

[0022] In this embodiment, the shell 1 has a gun-like shape, and a handle is provided at the bottom thereof to facilitate operation by medical personnel.

[0023] In this embodiment, the directions allowed to pass through the two first one-way valves 8 are from the side close to the main inflation path 6 to the side away from the main inflation path 6, that is, it is ensured that the gas can only enter the two storage tanks through the first one-way valve 8, and cannot flow out of the two storage tanks through the first one-way valve 8. The direction allowed to pass through the second one-way valve 10 is from the side close to the pressure rod 9 to the side away from the pressure rod 9, so that when the piston 5 moves to the right, gas can be filled into the inflation chamber 4 on the left through the second one-way valve 10.

[0024] In this embodiment, an air inlet 15 communicating with the outside is opened on the side wall of the inflation chamber 4 away from the main inflation path 6, so that the inflation chamber 4 on the right side of the piston 5 is connected with the outside through the air inlet 15, thereby continuously replenishing air.

[0025] In this embodiment, a first mounting interface 16 and a second mounting interface 17 are respectively provided on the top of the shell 1, the inlet end of the first delivery pipe 13 and the air outlet end of one of the inflation branches 7 are both arranged inside the first mounting interface 16, the inlet end of the second delivery pipe 14 and the air outlet end of the other inflation branch 7 are both arranged inside the second mounting interface 17, the first mounting interface 16 and the second mounting interface 17 are both provided with internal threads, and the tank mouths of the liquid medicine storage tank 2 and the ointment storage tank 3 are both provided with external threads, the tank mouth of the liquid medicine storage tank 2 is threadedly connected to the first mounting interface 16, and the tank mouth of the ointment storage tank 3 is threadedly connected to the second mounting interface 17.

[0026] In this embodiment, a first sealing gasket is provided inside the first mounting interface 16 between the end face of the tank mouth of the liquid medicine storage tank 2 and the bottom surface of the first mounting interface 16, and a second sealing gasket is provided inside the second mounting interface 17 between the end face of the tank mouth of the ointment storage tank 3 and the bottom surface of the second mounting interface 17. The setting of 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 drug leakage.

[0027] In this embodiment, the normally closed on-off valve 18 includes a valve chamber disposed within the housing 1. The two sides of the valve chamber are connected to corresponding delivery pipes. A valve core 181 is slidably mounted within the valve chamber. The valve core 181 is in sealed sliding connection with the sidewalls of the valve chamber. A liquid passage hole 182 is provided 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. The button 184 extends to the outside of the housing through a through-hole in the housing. Pressing the button 184 pushes the valve core 181 to overcome the elastic force of the spring 183, thereby aligning the liquid passage hole 182 with the interfaces of the delivery pipes on both sides of the valve chamber, ensuring that the liquid or ointment can be discharged normally through the delivery pipes.

[0028] In this embodiment, the button 184 of the normally closed switch valve 18 connected to the first delivery pipe 13 is located at the top of the shell 1, and the button 184 of the normally closed switch valve 18 connected to the second delivery pipe 14 is located at the bottom of the shell 1. The two buttons 184 are respectively arranged at the top and top of the shell 1, which can prevent medical staff from pressing the wrong button.

[0029] In this embodiment, a mounting slot is defined on the housing 1 at the end away from the pressure rod 9, between the atomizing nozzle 11 and the ointment outlet 12. A rotating shaft 19 is fixedly connected between the top and bottom walls of the mounting slot. A mounting base 20 is rotatably connected to the rotating shaft 19. A brush rod 21 is detachably mounted on the mounting base 20. A brush head 22 is fixedly connected to the end of the brush rod 21 away from the mounting base 20. When the ointment needs to be evenly applied after application, the brush rod 21 can be rotated so that the brush head 22 faces the outside of the mounting slot, thereby facilitating even application of the ointment using the brush head 22. The brush rod 21 is detachably connected to the mounting base 20, facilitating removal and replacement after use.

[0030] In this embodiment, one end of the brush rod 21 is threadedly mounted in a threaded hole on the mounting base 20. In other embodiments, the brush rod 21 and the mounting base 20 may also be plugged in.

[0031] In this embodiment, the mounting seat 20 and the rotating shaft 19 are connected in a damped rotation manner.

[0032] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
