Description

Technical Field

[0001] This utility model relates to the field of nasal cavity cleaning technology, and in particular to a nasal cavity cleaning device for pediatric clinical use. Background Technology

[0002] When children have illnesses such as colds or rhinitis, their nasal cavities produce secretions that form nasal mucus. Because young children do not know how to forcefully blow out the mucus blocking their nasal cavities like adults, the mucus cannot be blown out and will absorb foreign objects and dry up over time, blocking the nostrils and affecting breathing. Therefore, it is necessary to clean the nasal cavity.

[0003] According to patent number CN215308248U, a utility model patent for a nasal cavity cleaning device for pediatric clinical use includes a base plate. The base plate is characterized by: a lower end of a support plate fixedly connected to the upper middle portion of its upper side; a material cylinder fixedly connected to the lower middle portion of its upper side; a vertical plate of an L-shaped plate fixedly connected to the upper side of the material cylinder; a motor fixedly connected to the middle portion of one side of the vertical plate of the L-shaped plate; the output shaft of the motor passing through the middle portion of the vertical plate of the L-shaped plate; and the end of the motor's output shaft fixedly connected to the center of a first bevel gear, which meshes with a second bevel gear. This utility model relates to the field of nasal cavity cleaning equipment, specifically to a nasal cavity cleaning device for pediatric clinical use. This device can prevent saline solution from entering deep into the nasal cavity of children due to the obstruction of an umbrella-shaped shielding disc, reducing discomfort for children.

[0004] While the above-mentioned technical solution can complete the cleaning of the nasal cavity of pediatric patients, when recycling the cleaning waste liquid, the inlet and outlet holes of this structure are similar in size, and the diameter of the umbrella-shaped shielding plate is much larger than the diameter of the double-hole tube. Therefore, it is difficult to successfully recycle the cleaning waste liquid during the cleaning process. In addition, the saline solution and the cleaning waste liquid share the same container, which will eventually cause the pollutants in the waste liquid to adhere to the inner wall of the container and contaminate the saline solution. Utility Model Content

[0005] The purpose of this invention is to provide a nasal cavity cleaning device for pediatric clinical use, which can not only clean the patient's nasal cavity and recycle the waste liquid after cleaning, but also prevent the waste liquid from contaminating the normal cleaning solution.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A nasal irrigation device for pediatric clinical use includes a support frame and a reservoir cylinder detachably connected to the upper end of the support frame. The reservoir cylinder has a hollow structure between its upper and lower ends. The reservoir cylinder includes a cylinder body with an opening at the lower end, a partition along the height direction of the inner wall of the cylinder body dividing it into a reservoir chamber and a waste liquid chamber, and a sealing cap that mates with and is detachably connected to the opening end of the cylinder body. The inner walls of the reservoir chamber and the waste liquid chamber are slidably connected to pistons along their length. The upper end of the outer wall of the cylinder body has downward-facing sliding holes at the positions of the reservoir chamber and the waste liquid chamber. Each piston has a sliding rod extending out of the corresponding sliding hole and slidably connected to its upper end. The inner wall of each sliding hole is fitted with a sealing ring. An electric push rod is installed at the upper end of the support frame, passing through the hollow part of the reservoir cylinder and extending out of its upper end. The upper end of the electric push rod is detachably connected to a fixing component for fixing the sliding rod. Each sliding rod is detachably connected to the fixing component.

[0008] A control valve connected to the lower end of one side of the outer wall of the liquid storage chamber is installed therein. A connecting pipe is connected to the upper part of one side of the outer wall of the waste liquid chamber. A cleaning assembly is provided on one side of the outer wall of the liquid storage cylinder. The cleaning assembly includes an operating pipe with an open upper end, an inlet hole and an outlet hole respectively opened on the left and right sides of the bottom of the operating pipe. A guide pipe connected to the inlet hole and extending out of its front end is provided inside the operating pipe. A drain pipe connected to the outlet hole is provided at the bottom of the outer wall of the operating pipe. A first water guide pipe connected to the rear end of the control valve and the guide pipe is detachably connected. A second water guide pipe connected to the rear end of the connecting pipe and the drain pipe is detachably connected. A water distribution assembly is provided between the left and right sides of the open end of the operating pipe. A control panel is provided on one side of the upper end of the support frame. The electric push rod is electrically connected to the control panel.

[0009] By adopting the above technical solution, when using the device, first power it on, operate the control panel to extend the electric push rod on the support frame and drive the corresponding piston to move upward along the inner wall of the reservoir and away from the sealing cap through the slide rod. Then, add physiological saline into the reservoir through the control valve, and then connect the first water guide tube to the control valve. Next, operate the control panel to shorten the electric push rod at a constant speed and drive the two slide rods to slide down through the fixing component. The physiological saline in the reservoir is sent to the inlet hole of the operating tube of the cleaning component through the first water guide tube and the air in the water guide tube is discharged. After the air is discharged, the medical staff hold the operating tube and insert it into the nasal cavity of the patient or child.

[0010] During this process, the saline solution sprayed from the infusion tube is dispersed by the water-spreading component to moisten the nasal cavity of the child patient. The moistened saline waste liquid flows into the operating tube and then into the waste liquid chamber through the drain tube and the second infusion tube. As the piston in the waste liquid chamber slides down, a negative pressure is formed between the upper end of the piston and the upper end of the inner wall of the storage chamber, so the waste liquid can be drawn into the waste liquid chamber quickly and rapidly. After use, the slide rod can be separated from the fixing component first, and the fixing component can be removed from the electric push rod. Then the storage cylinder can be removed from the support frame, and the sealing cap can be removed to clean and disinfect the cylinder body and piston.

[0011] A further feature of this invention is that the upper end of the inner wall of the support frame is provided with a first internal thread, the lower end of the outer wall of the cylinder is provided with a first external thread that is threadedly connected to the first internal thread, the outer wall of the sealing cover is provided with a second external thread, and the lower end of the inner wall of the cylinder is provided with a second internal thread that is threadedly connected to the second external thread.

[0012] By adopting the above technical solution, it is easy to quickly disassemble and assemble the liquid storage cylinder and sealing cap.

[0013] A further feature of this invention is that the fixing component includes a connecting rod, positioning holes on the left and right sides of the upper end of the connecting rod, fixing blocks on the left and right sides of the upper end of the connecting rod, threaded holes on one side of the outer wall of each fixing block, and fixing bolts threadedly connected to the threaded holes. Each sliding rod has a fixing hole on the upper end of one side of its outer wall that mates with the corresponding fixing bolt.

[0014] By adopting the above technical solution, not only can the corresponding slide bar be flexibly fixed, but when the waste liquid in the waste liquid chamber is discharged, the corresponding slide bar in the storage chamber can be loosened, reducing the workload of the electric push rod and accelerating the discharge of waste liquid.

[0015] A further feature of this invention is that the water distribution assembly includes an arc-shaped, inwardly recessed water distribution plate and support rods respectively disposed on the left and right sides of the lower end of the water distribution plate.

[0016] A further feature of this invention is that a conical water-breaking needle is provided at the middle position of the upper end of the inner wall of the water distribution plate.

[0017] By adopting the above technical solution, the water column sprayed on the water distribution plate can be broken up to reduce the impact force, and after contacting the water distribution plate, the diffused water body can be further diffused and the impact of the water flow can be reduced again, thus avoiding discomfort to children.

[0018] In summary, this utility model has the following beneficial effects:

[0019] Firstly, this utility model can not only clean the patient's nasal cavity and recycle the waste liquid after cleaning, but also prevent the waste liquid from contaminating the normal cleaning solution.

[0020] Secondly, the liquid storage cylinder of this utility model can not only store waste liquid and physiological saline at the same time without affecting each other, but also can be removed after use for thorough cleaning and disinfection to avoid residue causing pollution.

[0021] Thirdly, the operating tube of this utility model not only makes it convenient for medical staff to clean the nasal cavity of children, but also allows waste liquid to be smoothly transported to the waste liquid chamber through the internal space of the operating tube;

[0022] Fourth, the fixing component of this utility model can not only control the lifting and lowering of two pistons simultaneously, but also allow the corresponding piston to work individually according to the actual situation and different working devices. Attached Figure Description

The fixing component 27 includes a connecting rod 28, positioning holes 29 on the left and right sides of the upper end of the connecting rod 28, fixing blocks 3 on the left and right sides of the upper end of the connecting rod 28, threaded holes 31 on one side of the outer wall of each fixing block 3, and two fixing bolts 32 that are threaded to the threaded holes 31 respectively. Each sliding rod 23 has a fixing hole 24 on the upper end of one side of its outer wall that mates with the corresponding fixing bolt 32. Each sliding rod 23 can be detachably connected to the positioning holes 29 on the connecting rod 28.

[0035] A control valve 33 is installed at the lower end of one side of the outer wall of the liquid storage chamber 19 and communicates with it. A connecting pipe 34 is connected to the upper side of one side of the outer wall of the waste liquid chamber 2. A cleaning assembly 35 is provided on one side of the outer wall of the liquid storage cylinder 11. The cleaning assembly 35 includes an operating pipe 36 with an open upper end, two inlet holes 37 and an outlet hole 38 respectively opened on the left and right sides of the bottom of the operating pipe 36. The diameter of the outlet hole 38 is larger than the diameter of the inlet hole 37. A guide pipe 39 is provided inside the operating pipe 36, which communicates with the inlet hole 37 and extends out of its front end opening. A drain pipe 4 is provided at the bottom of the outer wall of the operating pipe 36, which communicates with the outlet hole 38. The control valve 33 and the rear end of the guide pipe 39 are detachably connected. There is a first water guide pipe 41 that is connected to the operation pipe 34. A second water guide pipe 42 that is connected to the operation pipe 36 is detachably connected to the operation pipe 34 and the drainage pipe 4. A water distribution assembly 43 is provided between the left and right sides of the opening end of the operation pipe 36. The water distribution assembly 43 includes an arc-shaped and inwardly recessed water distribution plate 44 and support rods 45 respectively provided on the left and right sides of the lower end of the water distribution plate 44. A conical water breaking needle 46 is provided at the middle position of the upper end of the inner wall of the water distribution plate 44. One end of the liquid guide pipe 39 that extends out of the operation pipe 36 corresponds to the water breaking needle 46. A control panel 47 is provided on one side of the upper end of the support frame 1. The electric push rod 26 is electrically connected to the control panel 47.

[0036] Usage: When using the device, first turn it on, operate the control panel 47 to extend the electric push rod 26 on the support frame 1, and drive the corresponding piston 21 along the inner wall of the reservoir 11 and the partition 13 to move upward and away from the sealing cover 14. Then, add physiological saline into the reservoir 19 through the control valve 33. Then connect the first water guide tube 41 to the control valve 33. Next, operate the control panel 47 to shorten the electric push rod 26 at a constant speed, and drive the two slide rods 23 along the sliding hole 22 through the fixing component 27. The physiological saline in the reservoir 19 is sent to the inlet hole 37 of the operating tube 36 of the cleaning component 35 through the first water guide tube 41, and the air in the guide tube 39 is expelled. After the air is expelled, the medical staff holds the operating tube 36 and inserts its front end into the nasal cavity of the patient or child.

[0037] During this process, the saline solution sprayed from the guide tube 39 is dispersed by the water-spreading component 43 and spreads to the surrounding area to moisten the nasal cavity of the child patient. The saline solution column sprayed from the guide tube 39 first contacts the water-breaking needle 46 and is initially broken and dispersed by the water-breaking needle 46. Then, the water-spreading plate 44 on the support rod 45 blocks the impact of the water flow and allows the water flow to spread outward along the inner wall of the water-spreading plate 44. The moistened saline waste liquid flows into the operating tube 36 and flows into the waste liquid chamber 2 along the drain pipe 4 on the outlet hole 38 and the second guide tube 42. Since the piston 21 in the waste liquid chamber 2 forms a negative pressure between the upper end of the piston 21 and the upper end of the inner wall of the storage chamber 19 during the downward movement, the waste liquid can be drawn into the waste liquid chamber 2 quickly and rapidly. The sealing ring 25 in the sliding hole 22 can further ensure the negative pressure state in the waste liquid chamber 2.

[0038] After use, first rotate the fixing bolt 32 in the threaded hole 31 on the corresponding rotating fixing block 3 on the liquid storage chamber 19 and move it away from the fixing hole 24 on the corresponding slide rod 23. Then extend the electric push rod 26 and remove the second water guide pipe 42 from the drain pipe 4 to drain the waste liquid in the waste liquid chamber 2. Then loosen the fixing bolt 32 on the waste liquid chamber 2 so that both slide rods 23 are separated from the positioning hole 29 on the connecting rod 28. Then remove the fixing component 27 from the electric push rod 26. Then rotate the first external thread 15 of the cylinder body 12 away from the first external thread 15 on the support frame 1 to remove the liquid storage cylinder 11 from the support frame 1. Then rotate the sealing cover 14 so that the second external thread 17 is away from the second internal thread 18 to remove the sealing cover 14. Then the inner wall of the cylinder body 12 and the piston 21 can be cleaned and disinfected.

[0039] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
