Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to an ear, nose and throat care spray device. Background Art

[0002] Ear, nose and throat diseases are common diseases. When treating ear, nose and throat diseases, the common method is to use drug spraying. For example, when using spray to treat rhinitis, this method generally sprays from the outside to the inside. A large amount of drug is sprayed outside the affected area, resulting in waste. In addition, when there is a large accumulation of body fluids (such as nasal discharge and saliva), the sprayed drug can be easily carried away by the body fluids, affecting the efficacy.

[0003] To this end, people have developed a spraying device, see application number 202210463091.7, invention name: Otorhinolaryngology medication device. This device delivers liquid medicine to the affected area through a catheter for spraying. Although this method solves the above technical problems, it still has the following technical problems:

[0004] Since there are bends in the ENT cavity, the front end of the device is easily blocked at the bend. Although the sphere can solve this problem to a certain extent, the effect is not ideal. In addition, when using a pull wire to fine-tune the position of the adsorption layer, the bend position affects the pull wire operation, resulting in unsatisfactory fine-tuning effect.

The trachea is connected to the interlayer; the second catheter and / or the first catheter form a transition portion between the balloon and the sphere, and a first elastic sheet is provided on the side of the balloon close to the adsorption layer, one end of the first elastic sheet is connected to the balloon, and the other end is connected to the sphere, and both sides are connected to the transition portion so that a first cavity is formed between the first elastic sheet and the transition portion; a second elastic sheet is provided on the side of the balloon away from the adsorption layer, one end of the second elastic sheet is connected to the balloon, and the other end is connected to the sphere, and both sides are connected to the transition portion so that a second cavity is formed between the second elastic sheet and the transition portion; both the first cavity and the second cavity can be inflated.

[0008] Optionally, a first air inlet pipe and a second air inlet pipe are provided at the rear end of the first conduit, the first air inlet pipe is communicated with the first cavity, and the second air inlet pipe is communicated with the second cavity.

[0012] Optionally, the adsorption layer is arranged near the outer edge of the balloon.

[0013] Optionally, the adsorption layer is arranged at a position corresponding to the spray port.

[0014] Optionally, the liquid inlet pipe is provided with a first joint, and a fourth valve is installed on the first joint or the liquid inlet pipe; the air inlet pipe is provided with a second joint, and a fifth valve is installed on the second joint or the air inlet pipe; and the first air inlet pipe is provided with a third joint;

[0016] Optionally, the width of one side of the balloon is greater than the width of the other side; the first catheter is arranged close to the side of the balloon with the larger width; and the adsorption layer is arranged on the side of the balloon with the smaller width.

[0017] When the ear, nose and throat care spray device provided by the present invention is used, the first catheter can be held in hand to push the ball into the cavity of the ear, nose and throat to the affected part, and air is supplied to the balloon through the air inlet pipe so that the balloon forms a support, and then the high-pressure liquid medicine is supplied to the liquid inlet pipe so that the medicine is sprayed on the affected part, saving resources; when there is a deviation between the spray port and the affected part, air is supplied to the first cavity through the first air inlet pipe so that the first elastic sheet moves in the direction away from the transition part, pulling the ball to rotate so that the spray port can rotate slightly toward the front end to spray forward, and air is supplied to the first cavity through the second air inlet pipe so that the second elastic sheet moves in the direction away from the transition part, pulling the ball to rotate so that the spray port can rotate slightly toward the rear end Rotating it causes it to spray backward, which can improve the accuracy of spraying. In the process of pushing the ball into the cavity of the ear, nose and throat, when the front end of the device is blocked at a bend: supplying air to the first cavity through the first air inlet pipe causes the first elastic piece to move away from the transition portion, pulling the ball to rotate. During the rotation of the ball, the part of the second conduit between the ball and the first conduit bends clockwise, which is conducive to avoiding obstacles on the side of the spraying port. Supplying air to the second cavity through the second air inlet pipe causes the second elastic piece to move away from the transition portion, pulling the ball to rotate. During the rotation of the ball, the part of the second conduit between the ball and the first conduit bends counterclockwise, which is conducive to avoiding obstacles on the side facing away from the spraying port.

[0018] For situations where there is a lot of body fluid, the drug solution can be applied or sprayed on the adsorption layer, and then the balloon can be driven to the diseased area through the ball, and gas can be supplied through the air inlet pipe to expand the balloon, and the adsorption layer can be pressed against the diseased area, and it can stay for a period of time to allow the drug to take effect. When there is a deviation in the front and back 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 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 and the balloon are pulled to rotate, so that the adsorption layer can rotate slightly toward the front end. In this way, the position of the adsorption layer can be fine-tuned. The invention is convenient for operation; 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 of 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 degree of deformation 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.

DETAILED DESCRIPTION

[0024] 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1, please refer to Figure 1 and Figure 2This embodiment provides an ear, nose and throat care spray device, including 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, and a vent 5 connected to the interior of the balloon is provided on the first catheter. 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 spray port 7 is provided on the sphere, and the spray port is connected to the interior 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 interior 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 conduit and / or the first conduit form a transition portion between the balloon and the sphere. A first elastic sheet 15 is provided 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 sphere, 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 provided 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 sphere, 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 provided at the rear end of the first conduit. And the second air intake pipe 20, the first air intake pipe is connected to the first cavity, and 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. This connecting structure and method are well known to those skilled in the art and will not be repeated here.

[0026] When the above-mentioned ear, nose and throat care spray device is used, the first catheter can be held in hand to push the ball into the cavity of the ear, nose and throat to the affected part, and air is supplied to the balloon through the air inlet pipe to form a support. Then, high-pressure liquid medicine is provided to the liquid inlet pipe to spray the medicine at the affected part, saving resources. When there is a deviation between the spray port and the affected part, air is supplied to the first cavity through the first air inlet pipe, so that the first elastic sheet moves away from the transition part, pulling the ball to rotate, so that the spray port can rotate slightly toward the front end to spray forward. Air is supplied to the first cavity through the second air inlet pipe, so that the second elastic sheet moves away from the transition part, pulling the ball to rotate, so that the spray port can rotate slightly toward the rear end. The spray is directed backwards, thereby improving the accuracy of the spray. When the sphere is pushed into the cavity of the ear, nose, and throat, if the front end of the device is blocked at a bend, air is supplied to the first cavity through the first air inlet pipe, causing the first elastic sheet to move away from the transition portion, pulling the sphere to rotate. During the rotation of the sphere, the portion of the second conduit between the sphere and the first conduit bends clockwise, which is conducive to avoiding obstacles on the side of the spray nozzle. Air is supplied to the second cavity through the second air inlet pipe, causing the second elastic sheet to move away from the transition portion, pulling the sphere to rotate. During the rotation of the sphere, the portion of the second conduit between the sphere and the first conduit bends counterclockwise, which is conducive to avoiding obstacles on the side facing away from the spray nozzle.

[0027] For situations where there is a lot of body fluid, the drug solution can be smeared or sprayed on the adsorption layer, and then the balloon can be driven to the diseased area through the sphere, and gas can be supplied through the air inlet pipe to expand the balloon, and the adsorption layer can be pressed against the diseased area, and it can stay for a while 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 sphere and the balloon 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 sphere and the balloon 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 degree of deformation 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. When the nasal and throat anti-inflammatory device is used, it can be used in conjunction with an endoscope when it cannot be directly observed with the naked eye. This is easy for those skilled in the art to think of.

[0028] For ease of use, a first connector 11 may be provided on the liquid inlet pipe, and a fourth 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 fifth valve 14 may be installed on the second connector or the air 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 the 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 the 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.

[0029] 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 that of 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, causing the gas to 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 area.

[0030] 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.

[0031] 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 and second cavities 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 being connected to the first cavity, and the second air outlet being connected to the second cavity; a first valve 21 is installed on the first air outlet, a second valve 22 is installed on the second air outlet, and a third valve 25 is installed on the vent. The first, second, and third valves are all solenoid valves or intelligent valves. This structure supplies air to the first and second cavities and the balloon by adjusting the valves, resulting in a simpler structure. During use, the first and second cavities can be simultaneously supplied with air to form a support structure that cooperates with the balloon support, making the sphere more stable during drug dispensing.

[0032] It should be noted that the inflation structure of the first cavity and the second cavity in the above embodiment can 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.
