[0002] ENT diseases are common diseases. The common method of treating ENT diseases is to use drug spraying. For example, spraying is used to treat rhinitis. This method is generally spraying from the outside to the inside. A large amount of medicine is sprayed outside the diseased part, which causes waste. In addition, when there is a lot of accumulation of body fluids (such as nasal mucus and saliva), the sprayed medicine is easily carried away by the body fluids, affecting the efficacy.

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

[0016] Example 1, please refer to Figure 1 and Figure 2 The present embodiment provides an ear, nose and throat care spraying device, comprising a first catheter 1 and a second catheter 2, the first catheter and the second catheter can be made of existing medical plastic catheter materials, the first catheter is sleeved on the outside of the second catheter, so that a sandwich 3 is formed between the first catheter and the second catheter; a balloon 4 is fixed on the first catheter near the front end, the first catheter is provided with a vent 5 connected to the inside of the balloon, and an adsorption layer 10 is provided on the balloon, wherein the adsorption layer can be a sponge layer or a cotton layer, etc.; a sphere 6 is provided at the front end of the second catheter, and a spraying port 7 is provided on the sphere, the spraying port is connected to the inside of the second catheter, and there is a distance between the sphere and the first catheter; a liquid inlet pipe 8 and an air inlet pipe 9 are provided at the rear end of the first catheter, the liquid inlet pipe is connected to the inside of the second catheter, and the air inlet pipe is connected to the sandwich. Generally, the adsorption layer can be arranged at a position close to the outer edge of the balloon, corresponding to the position of the spray port, and the second catheter and / or the first catheter form a transition portion between the balloon and the ball head. A first elastic sheet 15 is arranged on the side of the balloon close to the adsorption layer, one end of the first elastic sheet is connected to the balloon, the other end is connected to the ball head, and both sides are connected to the transition portion so that a first cavity 16 is formed between the first elastic sheet and the transition portion; a second elastic sheet 17 is arranged on the side of the balloon away from the adsorption layer, one end of the second elastic sheet is connected to the balloon, the other end is connected to the ball head, and both sides are connected to the transition portion so that a second cavity 18 is formed between the second elastic sheet and the transition portion; a first air inlet pipe 19 is arranged at the rear end of the first catheter and the second air intake pipe 20, the first air intake pipe is connected to the first cavity, the second air intake pipe is connected to the second cavity. In this embodiment, the structure for connecting the first air intake pipe and the first cavity can use the existing structure, such as directly passing through the interlayer from the rear end of the first conduit to connect with the first cavity. Similarly, the second air intake pipe can also be arranged to directly pass through the interlayer from the rear end of the first conduit to connect with the second cavity; or the interlayer is isolated into a first interlayer, a second interlayer and a third interlayer, the air intake pipe and the air vent are connected to the first interlayer, the first air intake pipe is connected to the second interlayer, the second air intake pipe is connected to the third interlayer, and the front end of the first conduit is provided with a hole connecting the second interlayer and the first cavity and a hole connecting the third interlayer and the second cavity. Such connecting structure and method are well known to those skilled in the art and will not be described in detail here.

[0017] When the above-mentioned ear, nose and throat care spray device is used, the first catheter can be held and the ball head can be pushed into the cavity of the ear, nose and throat to the affected part, and the balloon can be supplied with air through the air inlet pipe so that the balloon forms a support, and then the medicine can be sprayed on the affected part by providing high-pressure liquid medicine through the liquid inlet pipe, thereby saving resources; when there is a deviation between the spray port and the affected part in front and behind, the first air inlet pipe is used to supply air to the first cavity so that the first elastic sheet moves away from the transition part, and the ball head is pulled to rotate so that the spray port can be slightly rotated toward the front end direction to spray forward, and the second air inlet pipe is used to supply air to the first cavity so that the second elastic sheet moves away from the transition part, and the ball head is pulled to rotate so that the spray port can be slightly rotated toward the rear end direction. The spray is made to spray backward, which can improve the accuracy of spraying. When the front end of the device is blocked at the bend during the process of pushing the ball head into the cavity of the ear, nose and throat, the first air inlet pipe is used to supply air to the first cavity so that the first elastic sheet moves away from the transition part and pulls the ball head to rotate. During the rotation of the ball head, the part of the second conduit between the ball and the first conduit is bent in the clockwise direction, which is conducive to avoiding obstacles on the side of the spraying port. The second air inlet pipe is used to supply air to the second cavity so that the second elastic sheet moves away from the transition part and pulls the ball head to rotate. During the rotation of the ball head, the part of the second conduit between the ball and the first conduit is bent in the counterclockwise direction, which is conducive to avoiding obstacles on the side of the spraying port. In the case of a large amount of body fluid, the drug solution can be smeared or sprayed on the adsorption layer, and then the balloon is driven to the diseased area through the ball body, and gas is provided through the air inlet pipe to expand the balloon, and the adsorption layer is pressed against the diseased area, and it stays for a period of time to allow the drug to take effect. When there is a deviation in the front and rear positions of the adsorption layer, the first air inlet pipe is used to supply air to the first cavity, so that the first elastic sheet moves away from the transition part, and the ball head and the balloon are pulled to rotate so that the adsorption layer can rotate slightly toward the rear end. The second air inlet pipe is used to supply air to the second cavity, so that the second elastic sheet moves away from the transition part, and the ball head and the balloon are pulled to rotate so that the adsorption layer can rotate slightly toward the front end. In this way, it is convenient to fine-tune the position of the adsorption layer. The fine-tuning effect is more ideal; when acting on the nasal cavity, nasal ventilation can be achieved through the liquid inlet tube. This method is also applicable to the method of using powder. Since the diameter of the second catheter is smaller than that of the first catheter, it is easy to deform relative to the first catheter. Therefore, when the ball is blocked at the bend of the cavity to the ear, nose and throat, the part of the second catheter between the ball and the first catheter is easy to deform so that the ball can continue to move along the bend of the cavity, thereby driving the position of the airbag to the bend, so as to facilitate the adsorption layer to align with the diseased part. The deformation degree of the part of the second catheter between the ball and the first catheter can be further adjusted by inflating the first cavity or the second cavity, thereby improving the ability of the device to pass the bend. The nasopharyngeal anti-inflammatory device can be used in conjunction with an endoscope when it cannot be directly observed by the naked eye, which is easy for those skilled in the art to think of.

[0018] For the convenience of use, a first connector 11 may be further provided on the liquid inlet pipe, and a first valve 12 may be installed on the first connector or the liquid inlet pipe; a second connector 13 may be provided on the air inlet pipe, and a second valve 14 may be installed on the second connector or the liquid inlet pipe, so that the opening and closing of the liquid inlet pipe can be controlled by the first valve, and the first connector is convenient for connecting to a corresponding liquid supply device, and the opening and closing of the air inlet pipe can be controlled by the second valve, and the second connector is convenient for connecting to a corresponding air supply device; of course, a third connector 23 may also be provided on the first air inlet pipe, and a third valve may also be installed on the third connector or the first air inlet pipe; a fourth connector 24 may also be provided on the second air inlet pipe, and a fourth valve may also be installed on the fourth connector or the second air inlet pipe.

[0019] As a preferred embodiment, weak portions are provided at positions on the balloon corresponding to the first cavity and the second cavity, wherein the weak portions can be set to have a thickness slightly smaller than the thickness at other positions, or to have existing forms such as a cross mark. In this way, once the gas pressure in the balloon is too high, the weak portion will be damaged first, and the gas will enter the first cavity and the second cavity, so that the gas will flow in a directional manner toward the first cavity and the second cavity to form a buffer, thereby preventing the balloon from directly exploding in an undirectional manner and impacting the diseased part.

[0020] As a preferred embodiment, the width of one side of the balloon is greater than that of the other side; the first catheter is arranged close to the side of the balloon with a larger width; the adsorption layer is arranged on the side of the balloon with a smaller width, which facilitates the adjustment of the position of the adsorption layer.

[0021] Example 2, see Figure 3 , the structure of Example 2 is roughly the same as that of Example 1, except that the inflation structure of the first cavity and the second cavity is different, specifically: the front end of the first catheter is provided with a first air outlet and a second air outlet, the first air outlet is connected to the first cavity, and the second air outlet is connected to the second cavity; the first air outlet is installed with a first valve 21, the second air outlet is installed with a second valve 22, and the vent is installed with a third valve 25, and the first valve, the second valve and the third valve are all solenoid valves or intelligent valves. This structure supplies air to the first cavity, the second cavity and the balloon by adjusting the valve, and the structure is simpler. When in use, the first cavity and the second cavity can be simultaneously supplied with air to form a support to cooperate with the balloon support to make the ball head more stable when discharging medicine.

[0022] It should be noted that the inflation structure of the first cavity and the second cavity in the above embodiment may also be implemented in other ways, as long as the function of both the first cavity and the second cavity being inflatable can be achieved, and no specific limitation is made here.
