Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of otolaryngology nursing, specifically to a nasal irrigator for otolaryngology nursing. Background Technology
[0002] A nasal irrigator is a tool used to clean the nasal cavity. It typically utilizes the bactericidal properties of saline or hypertonic saline solution and the force of the water flow to expel abnormal secretions such as mucus, bacteria, allergens, and purulent discharge from the nasal cavity, restoring its normal physiological environment and thus protecting the nasal passages. Nasal irrigators come in various types, including simple bottle-type, handheld airbag-type, and electric water jet-type nasal irrigators.
[0003] Existing water-flow nasal irrigators utilize the bactericidal effect of saline or hypertonic saline and the impact force of the water flow to expel abnormal secretions such as nasal mucus, bacteria, allergens, and purulent discharge from the nasal cavity. However, they still have the following drawbacks: when there are many patients, the same bottle of saline or hypertonic saline may be used by two or more patients, increasing the risk of cross-infection. Utility Model Content
[0004] The purpose of this invention is to provide a nasal irrigator for ENT care, in order to solve the problem that the same bottle of saline or hypertonic saline may be used by two or more patients, increasing the risk of cross-infection.
[0005] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a nasal irrigator for ENT care, comprising a mounting post, an annular groove at one end of the mounting post, a replacement cylinder threadedly connected inside the annular groove, a mounting groove inside the mounting post, a water pump inside the mounting groove, a positioning groove at one end of the replacement cylinder, the positioning groove being rotatably inserted into the annular groove, a water extraction hole at the bottom of the positioning groove, a sealing sheet detachably installed inside the water extraction hole, a fixing cylinder fixed at one end of the replacement cylinder, a connecting hole at one end of the fixing cylinder, and an extraction tube fixed at one end of the fixing cylinder, the connecting hole and the central axis of the extraction tube being on the same straight line.
[0006] Preferably, a threaded cylinder is threadedly connected to the drain pipe of the water pump, and a nasal irrigation tube is fixed to one end of the threaded cylinder.
[0007] Preferably, the inner wall of the positioning groove is provided with a limiting groove, and the inner wall of the annular groove is fixed with a limiting ring, wherein the limiting ring and the limiting groove are slidably configured.
[0008] Preferably, a first sealing ring is fixed to one end of the mounting post, and a second sealing ring is fixed to one end of the inside of the threaded cylinder.
[0009] Preferably, the surface of the replacement cylinder is surrounded by an electric heating cup sleeve, and a loop is fixed on the electric heating cup sleeve.
[0010] Preferably, a temperature sensor is installed inside the electric heating cup sleeve, and a PLC controller is installed on the surface of the mounting column. The electric heating cup sleeve is electrically connected to the PLC controller, and the temperature sensor is electrically connected to the PLC controller.
[0011] Compared with existing technologies, a nasal irrigator for ENT care that adopts the above-mentioned technical solution has the following beneficial effects:
[0012] First, medical staff will align the positioning groove with the annular groove at one end of the replacement cylinder. Then, the staff will screw the end of the replacement cylinder in the positioning groove into the annular groove, thus fixing the mounting column and the replacement cylinder together. As the replacement cylinder is screwed into the annular groove, the end of the water pump's suction pipe gradually applies increasing pressure to the sealing plate. Since the sealing plate is fixed inside the suction hole through physical sealing and easy-open design, the sealing plate will be pushed out of the suction hole by the water pump's suction pipe. The cleaning fluid inside the replacement cylinder can then be extracted using the extraction pipe and the water pump. Medical staff can assign one or more replacement cylinders containing cleaning fluid to one patient, avoiding the reuse of replacement cylinders and reducing the risk of cross-infection.
[0013] 2. When medical staff screw the threaded cylinder onto the drain pipe of the water pump, the drain pipe of the water pump will squeeze one side of the second sealing ring, which will increase the sealing between the threaded cylinder and the drain pipe of the water pump. When the replacement cylinder and the mounting column are installed together, the first sealing ring will squeeze and fit between the mounting column and the inner end of the positioning groove, thereby increasing the sealing when the mounting column and the replacement cylinder are installed together.
[0014] Third, when using the nasal irrigation tube, medical staff will place the heating cup sleeve over the replaced tube to increase the temperature of the cleaning solution inside. As the heating cup sleeve heats the cleaning solution inside the tube, a temperature sensor monitors the temperature inside the heating cup sleeve in real time. When the cleaning solution inside the tube reaches a suitable temperature, the temperature sensor detects this and sends an electrical signal to the PLC controller. Subsequently, the PLC controller sends an electrical signal to the heating cup sleeve. Upon receiving the electrical signal, the heating cup sleeve will stop working to prevent the cleaning solution from becoming too hot, thus increasing the patient's comfort during nasal irrigation.

[0020] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0021] like Figures 1-4 As shown, a nasal irrigator for ENT care includes a mounting post 1. One end of the mounting post 1 has an annular groove 3, and a replacement cylinder 2 is threadedly connected inside the annular groove 3. The mounting post 1 has a mounting groove 4 inside, and a water pump 5 is installed inside the mounting groove 4. One end of the replacement cylinder 2 has a positioning groove 6, which is rotatably inserted into the annular groove 3. The bottom end of the positioning groove 6 has a water extraction hole 7, and a sealing plate 8 is detachably installed inside the water extraction hole 7. One end of the replacement cylinder 2 is fixed with a fixing cylinder 9, and one end of the fixing cylinder 9 has a connecting hole 10. One end of the fixing cylinder 9 is fixed with an extraction tube 11. The central axis of the connecting hole 10 and the extraction tube 11 are on the same straight line. A threaded cylinder 12 is threadedly connected to the drain pipe of the water pump 5, and a nasal irrigation tube 13 is fixed to one end of the threaded cylinder 12.
[0022] During use, medical staff first align the positioning groove 6 with the annular groove 3 at one end of the replacement cylinder 2. Then, the staff screws the end of the replacement cylinder 2 in the positioning groove 6 into the annular groove 3, thus fixing the mounting column 1 and the replacement cylinder 2 together. As the replacement cylinder 2 is screwed into the annular groove 3, the end of the water pump 5's suction pipe gradually applies increasing pressure to the sealing plate 8. Since the sealing plate 8 is fixed inside the suction hole 7 through physical sealing and easy-opening design, the sealing plate 8 will be pushed out of the suction hole 7 by the water pump 5's suction pipe. The cleaning fluid inside the replacement cylinder 2 can then be extracted using the extraction pipe 11 and the water pump 5. Medical staff can use one or more bottles of the replacement cylinder 2 containing cleaning fluid for each patient, avoiding the reuse of the replacement cylinder 2 and reducing the risk of cross-infection.
[0023] like Figures 2-4 As shown, a limiting groove 15 is formed on the inner wall of the positioning groove 6, and a limiting ring 14 is fixed on the inner wall of the annular groove 3. The limiting ring 14 and the limiting groove 15 are slidably arranged. A first sealing ring 16 is fixed at one end of the mounting column 1, and a second sealing ring 17 is fixed at one end of the threaded cylinder 12.
[0024] During use, when medical staff screw the threaded cylinder 12 onto the drain pipe of the water pump 5, the drain pipe of the water pump 5 will press against one side of the second sealing ring 17, which will increase the sealing between the threaded cylinder 12 and the drain pipe of the water pump 5. When the replacement cylinder 2 and the mounting column 1 are installed together, the first sealing ring 16 will press against one end of the mounting column 1 and the positioning groove 6, thereby increasing the sealing when the mounting column 1 and the replacement cylinder 2 are installed together.
[0025] like Figure 2 and Figure 4 As shown, the surface of the replacement cylinder 2 is surrounded by an electric heating cup sleeve 18, and a loop 19 is fixed on the electric heating cup sleeve 18. A temperature sensor 20 is installed inside the electric heating cup sleeve 18. A PLC controller is installed on the surface of the mounting column 1. The PLC controller is a Siemens 6ES7511-1AK02-0AB0. The electric heating cup sleeve 18 is electrically connected to the PLC controller, and the temperature sensor 20 is electrically connected to the PLC controller.
[0026] During use, when medical staff use the replacement tube 2, they will put the electric heating cup sleeve 18 on the replaced replacement tube 2 to increase the temperature of the cleaning fluid inside the replacement tube 2. When the electric heating cup sleeve 18 heats the cleaning fluid inside the replacement tube 2, the temperature sensor 20 will monitor the temperature inside the electric heating cup sleeve 18 in real time. When the cleaning fluid inside the replacement tube 2 is heated to a suitable temperature, the temperature sensor 20 will detect it and send an electrical signal to the PLC controller. Subsequently, the PLC controller will send an electrical signal to the electric heating cup sleeve 18. After receiving the electrical signal, the electric heating cup sleeve 18 will stop working to avoid the cleaning fluid temperature from becoming too high, thus increasing the patient's comfort during nasal irrigation.
[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
