Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a Eustachian tube insufflator with pressure display. Background Art

[0002] A Eustachian tube inflator is a medical device used to treat middle ear effusion, Eustachian tube obstruction, and retracted eardrums. Marketed, these devices are generally available in manual and electric versions, each consisting of a silicone nasal plug, an air pump / airbag, and an air tube. A typical Eustachian tube inflator works by tightening one nostril with a silicone plug and pressing the other with an index finger to prevent air leaks. Once both nostrils are sealed, the device is used to blow air into the nostril to create positive pressure, balancing the internal and external pressures of the Eustachian tube. However, commercially available Eustachian tube inflators have the following drawbacks:

[0003] First, the air pressure is uncontrollable, and constant pressure cannot be achieved, nor can the air pressure value be displayed in real time. Among them, if the electric type runs out of power and air pressure at a later stage, there will be no impact force, and multiple operations will be required to achieve the desired effect; and the manual transmission force is difficult to control, and excessive force increases the risk of secondary injury to the patient;

[0004] The second is a single silicone nasal plug. When the patient uses the Eustachian tube inflator, they have to press it with their index finger to prevent air leakage, which increases the risk of cross-contamination between the patient and the device.

[0005] The third is the electric Eustachian tube inflator, which is powered by dry batteries, which have a short lifespan and small capacity, requiring frequent battery replacement. At the same time, it is not environmentally friendly.

[0006] Therefore, it is more important to provide a Eustachian tube insufflator that can collect air pressure values, display them in real time, and prevent cross infection. Utility Model Content

[0007] In view of this, the present invention proposes a Eustachian tube insufflator with pressure display, aiming to solve the problems existing in the prior art.

[0008] Specifically, the utility model provides a Eustachian tube inflator with pressure display, comprising a housing and:

[0009] A silicone nose plug disposed on the top of the housing for inflating one nostril;

[0010] an air pump disposed inside the housing for generating an air flow;

[0011] An airway disposed inside the housing and configured to guide the airflow generated by the air pump to the silicone nasal plug;

[0012] a control panel disposed inside the housing for controlling the operation of the air pump;

[0013] An air pressure sensor disposed on the control panel for collecting air pressure data;

[0014] A lithium battery disposed inside the housing for providing a DC regulated power supply to the control panel;

[0015] and a control panel for parameter setting, which is arranged on one side of the housing and connected to the control panel.

[0016] Based on the above solution, the parameters include power, air pressure and air pump gear.

[0017] Based on the above solution, the silicone nasal plug includes an air-guiding nasal plug connected to the airway tube and a blocking nasal plug for closing one nostril.

[0018] On the basis of the above solution, it further includes a three-way connector provided on the airway tube for respectively connecting the air pump, the air pressure sensor and the air-guiding nasal plug.

[0019] On the basis of the above solution, it further includes: a constant voltage chip arranged on the control board for stabilizing the output voltage.

[0020] On the basis of the above solution, it also includes: a Type-C interface provided on the shell for charging the lithium battery.

[0021] On the basis of the above solution, the housing includes:

[0022] Front cover for fixing the control panel and protecting internal components;

[0023] A rear shell provided at the rear of the front shell for fixing the lithium battery, the air pump and the air duct;

[0024] An upper shell is arranged on the top of the front shell and the rear shell and is used to fix the silicone nasal plug and the airway.

[0025] On the basis of the above scheme, the silicone nasal plug is a pluggable airtight silicone nasal plug.

[0026] This new device can display air pressure in real time during use, providing doctors and patients with a basis for treatment plans and treatment results data. Each person's air-conducting and obstructing nasal plugs can be replaced during use, making them disposable or one-for-one, effectively preventing cross-infection. The airtight silicone nasal plugs can be directly plugged in and out, improving the work efficiency of medical staff. The use of a voltage-stabilizing chip ensures constant and stable air pressure, preventing the possibility of insufficient pressure, which can lead to unsatisfactory treatment effects, or excessive pressure, which can cause secondary harm to patients. Furthermore, this device is easy to operate, maintains stable air pressure, is safe to use, and has a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

It should be noted that, unless there is a conflict, the embodiments of the present invention and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] Example 1

[0035] like Figure 1-3 As shown, a Eustachian tube insufflator with pressure display includes a shell 1, a silicone nasal plug 2 arranged on the top of the shell 1 for inflating one nostril, an air pump 3 arranged inside the shell 1 for generating airflow, an air guide tube 4 arranged inside the shell 1 for guiding the airflow generated by the air pump 3 to the silicone nasal plug 2, a control board 5 arranged inside the shell 1 for controlling the operation of the air pump 3, an air pressure sensor 6 arranged on the control board 5 for collecting air pressure data, and a lithium battery 7 arranged inside the shell 1 for providing a DC regulated power supply for the control board 5.

[0036] The Eustachian tube insufflator uses a single silicone nasal plug to insufflate the Eustachian tube on the side that needs treatment. Figure 4 As shown, the silicone nasal plug 2 includes an air-conducting nasal plug 2-1 and a blocking nasal plug 2-2, wherein the air-conducting nasal plug 2-1 is connected to the airway 4 for inflation, and the other blocking nasal plug 2-2 plays a positioning role.

[0037] As a specific embodiment, it also includes a control panel 8 for parameter setting provided on the housing 1, which can display the data collected by the air pressure sensor, battery management, air pressure value display and air pump gear adjustment.

[0038] Specifically, the housing 1 includes a front housing 1-1 for securing the control panel 5 and protecting the internal components; a rear housing 1-2 disposed at the rear of the front housing 1-1 for securing the lithium battery 7, air pump 3, and airway tube 4; and an upper housing 1-3 disposed atop the front and rear housings 1-1, 1-2 for securing the silicone nasal plug 2 and airway tube 4. The silicone nasal plug 2 is used for the application portion of the patient's treatment, ensuring close contact with both nostrils and a sealed state. To ensure airflow through a predetermined channel, the silicone nasal plug 2 must have a certain sealing performance. The air pump 3 generates airflow to regulate the pressure in the Eustachian tube, helping to balance the air pressure in the middle ear and alleviate the symptoms of otitis media.

[0039] In order to stabilize the input voltage at a constant output voltage without being affected by changes in the input voltage and load, as a specific implementation scheme, it further includes: a constant voltage chip arranged on the control board 5.

[0040] like Figure 4-5 As shown, as a specific embodiment, it also includes a three-way connector 9 provided on the airway tube 4 for connecting the air pump 3, the air pressure sensor 6 and the silicone nasal plug 2 respectively. When the device is in operation, the air pressure sensor 6 transmits data to the control board 5. At the same time, the air pressure sensor 6, the air pump 3, and the lithium battery 7 are all electrically connected to the control board 5 via wires. The control panel 8 is connected to the control board 5, and the air pressure value, the air pump gear position, the battery level, etc. are displayed on the control panel 8.

[0041] In this embodiment, the control panel 8 can adopt conventional commercially available equipment, which does not belong to the innovation of the present invention and will not be described in detail here.

[0042] In order to meet the charging requirements of the lithium battery 7 , the device further includes: a Type-C interface 10 provided on the housing 1 for charging the lithium battery 7 .

[0043] Example 2

[0044] Based on Example 1, the present application provides a detailed operating instruction for a Eustachian tube inflator with a pressure display. The button functions include sw1: PWM adjustment of the air pump speed; sw2: pressing the button to start the air pump, and releasing the button to stop the air pump; sw3: long pressing to turn the machine on and off (shutdown is the STM32 standby mode, and the measured standby current of this board is 4.5uA);

[0045] LED lights: The first row of two digital tubes displays the air pressure value in kPa; the second row of two lights are air pump gear indicator lights, 1st gear PWM 50% duty cycle, one light is on; 2nd gear PWM 100% duty cycle, two lights are on; the third row of one light is always on when the power is turned on and off when the power is turned off.

[0046] When the device is turned off, inserting a Type-C cable activates the motherboard (wakes up from standby mode), and the first exhaust pressure indicator light serves as a charging indicator light, with a progress bar dynamically displaying how much power is currently charged. When the device is turned on, inserting a USB cable switches directly to charging and displays the charging status.

[0047] During normal operation, the air pump gear position is written into FLASH and can be saved when the power is off; when the battery voltage is lower than 3.7V, the machine will automatically shut down; after the machine is turned on, the countdown will start 3 minutes, and if no key is pressed, the machine will automatically shut down.

[0048] The Eustachian tube inflator of this utility model can display the air pressure in real time when used by the patient, and can provide the basis for the treatment plan and the treatment result data for the doctor and the patient; when in use, each person has two replaceable silicone nasal plugs, which can be used as disposable or one-person-one-use, effectively preventing cross infection, and the airtight silicone nasal plugs can be directly plugged in and out, improving the work efficiency of medical staff; the voltage stabilizing chip is used, and the air pressure is continuously stable, which solves the problem of insufficient pressure, failure to achieve the expected treatment effect or excessive pressure, causing secondary harm to the patient.

[0049] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
