Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a nasal irrigation circulation system. Background Technology

[0002] Nasal drug delivery is a treatment method that achieves drug absorption through the nasal mucosa. To improve the absorption and distribution of drugs delivered via the nose, the optimization of nasal administration of low-dose nasal corticosteroids and antibiotics involves extensive testing and design of the spray device's kinetic energy and droplet morphology to maximize drug absorption and distribution. However, for some traditional Chinese medicines and herbal ingredients that require a large dose and prolonged residence in the nasal cavity to exert their effects, a nasal drug circulation treatment method and device are needed. This device works by using two tubing connected to the left and right nostrils and the device via a motor-driven pump to deliver the medication to one nasal cavity. The medication is then drawn from the opposite nasal cavity, filtered, and re-injected into the previously used nasal cavity, repeating this cycle to achieve a prolonged, high-dose residence of the medication within the nasal cavity. This method aligns with the slow absorption characteristics of large doses of traditional Chinese medicine preparations, playing a positive role in the treatment of nasal diseases with traditional Chinese medicine and reducing the widespread use of antibiotics and corticosteroids.

[0003] However, in the process of treating a large number of patients in medical institutions, disinfection and prevention of cross-infection are particularly important issues, and also the weak links of this method. In some Chinese medicine hospitals and clinics, when using drug circulation equipment to perform 10-20 minute circulation treatment of Chinese medicine in the nasal cavity, disposable nasal contact nozzles are used to prevent cross-infection. However, the internal tubing of the equipment that provides circulation energy cannot be replaced. Even if the tubing is disinfected with disinfectant before each use, there is still a risk of incomplete disinfection and easy cross-infection. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0060] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the nasal irrigation circulation system provided in this application includes at least one irrigation pump 1, at least one suction pump 2, an irrigation tubing system, and a circulation tubing system;

[0061] The output of the irrigation pump 1 is used to supply liquid into one nasal cavity; the input of the suction pump 2 is used to extract liquid into the other nasal cavity.

[0062] The flushing pipeline system includes a first liquid supply pipeline 9 and a first discharge pipeline 3. The first liquid supply pipeline 9 is connected between the liquid supply tank 4 and the input end of the flushing pump 1, so that the flushing pump 1 can draw first liquid from the liquid supply tank 4 through the first liquid supply pipeline 9. The first discharge pipeline 3 is connected between the waste liquid tank 5 and the output end of the suction pump 2, so that the suction pump 2 can discharge the waste liquid drawn from the nasal cavity into the waste liquid tank 5 through the first discharge pipeline 3.

[0063] The circulation pipeline system includes: a second supply pipeline 6 and a second discharge pipeline 7. The second supply pipeline 6 is connected between the circulation tank 8 and the input end of the flushing pump 1, so that the flushing pump 1 can draw the second liquid from the supply tank 4 through the second supply pipeline 6. The second discharge pipeline 7 is connected between the circulation tank 8 and the output end of the suction pump 2, so that the suction pump 2 can discharge the circulating medicine solution drawn from the nasal cavity into the circulation tank 8 through the second discharge pipeline 7, which facilitates the recycling of the medicine solution. In addition, the circulation tank 8 is equipped with a filtration device, which can adopt a filter screen or other structure to filter the liquid entering the circulation tank 8.

[0064] When applying this solution, take physiological saline as the first liquid and Chinese / Western medicine or disinfectant as the second liquid as an example.

[0065] In the rinsing mode, the rinsing pump 1 draws the first liquid through the first liquid supply line 9 and supplies it into one nasal cavity. The suction pump 2 discharges the liquid drawn from the other nasal cavity into the waste tank 5 through the first discharge line 3. In this mode, secretions, crusts, inhaled pathogens, autologous pathogens and other substances in the patient's nasal cavity can be removed. It can also clean the nasal cavity environment for the next circulation mode and reduce the number and concentration of pollutants during the circulation process.

[0066] In circulation mode, taking the second liquid as a Chinese / Western medicine treatment agent as an example, the rinsing pump 1 draws the second liquid through the second liquid supply line 6 and supplies it into one nasal cavity, while the suction pump 2 discharges the liquid drawn from the other nasal cavity into the circulation tank 8 through the second discharge line 7. In this mode, drug circulation treatment can be performed, so that the drug can fully contact the nasal mucosa and meet the treatment requirements of sufficient drug contact time with the nasal mucosa.

[0067] Taking the second liquid as a disinfectant as an example, the flushing pump 1 draws the second liquid through the second liquid supply line 6 and supplies it into one nasal cavity. The suction pump 2 draws the liquid from the other nasal cavity and discharges it into the circulation tank 8 through the second discharge line 7. In this mode, the second liquid is a medical disinfectant. After the circulation process reaches the specified time, the pathogens and contaminants attached to the inner wall of the pipeline system will be removed to meet the requirements of medical disinfection standards.

[0068] In this solution, the nasal irrigation circulation system is independent of each other because the first supply pipe 9 and the first discharge pipe 3 in the irrigation pipeline system, the second supply pipe 6 and the second discharge pipe 7, the supply tank 4, the circulation tank 8 and the waste tank 5 in the circulation pipeline system are all independent. This can effectively alleviate the problem in the prior art where the internal pipelines of the equipment providing circulation power are irreplaceable and different agents are used in the same pipeline system, which poses a risk of cross-infection.

[0069] The following describes several different structural forms of the nasal irrigation circulation system in practical applications:

[0070] Example 1

[0071] like Figure 1 As shown, in the nasal irrigation circulation system provided in this embodiment, one irrigation pump 1 and one suction pump 2 are each configured;

[0072] The output ends of the first liquid supply line 9 and the second liquid supply line 6 are connected to the input end of the flushing pump 1 via the first tee structure 10 and then via the pipeline A11.

[0073] The input ends of the first discharge pipeline 3 and the second discharge pipeline 7 are connected to the output end of the suction pump 2 via the second tee structure 12 and then via pipeline B13.

[0074] In the rinsing mode, the rinsing pump 1 sequentially draws the first liquid through the first liquid supply line 9 and the line A11 and supplies it into one nasal cavity. The suction pump 2 sequentially discharges the liquid drawn from the other nasal cavity into the waste tank 5 through the line B13 and the first discharge line 3.

[0075] In circulation mode, the flushing pump 1 sequentially draws the second liquid through the second liquid supply line 6 and line A11 and supplies it into one nasal cavity. The suction pump 2 sequentially discharges the liquid drawn from the other nasal cavity through line B13 and the second discharge line 7 to the circulation tank 8.

[0085] In the rinsing mode, the rinsing pump A15 draws the first liquid through the first liquid supply line 9 and supplies it into one nasal cavity. The suction pump 2 discharges the liquid drawn from the other nasal cavity into the waste tank 5 through the line C19 and the first discharge line 3.

[0086] In circulation mode, the flushing pump B16 draws the second liquid through the second liquid supply line 6 and supplies it into one nasal cavity. The suction pump 2 draws the liquid from the other nasal cavity and discharges it into the circulation tank 8 through the line C19 and the second discharge line 7.

[0087] In addition, solenoid valves 14 are respectively installed on the first discharge pipe 3 and the second discharge pipe 7 to regulate the opening and closing of the first discharge pipe 3 and the second discharge pipe 7 respectively.

[0089] In circulation mode, the solenoid valve 14 on the first discharge pipe 3 is closed, and no liquid flows in the pipe. The solenoid valve 14 on the second discharge pipe 7 is open, allowing liquid to flow in the pipe.

The suction pump A20 discharges the liquid drawn from the other nasal cavity into the circulation tank 8 through the second discharge pipeline 7.

[0098] In addition, solenoid valves 14 are respectively installed on the first liquid supply line 9 and the second liquid supply line 6 to regulate the opening and closing of the first liquid supply line 9 and the second liquid supply line 6 respectively.

[0099] For example, in the flushing mode, the solenoid valve 14 on the first liquid supply line 9 is in the open state, allowing liquid to flow in the line, while the solenoid valve 14 on the second liquid supply line 6 is in the closed state, and no liquid flows in the line.

[0108] The second discharge pipe 7 is connected between the circulation tank 8 and the output end of the suction pump C27;

[0109] In the rinsing mode, the rinsing pump C25 draws the first liquid through the first liquid supply line 9 and supplies it into one nasal cavity, while the suction pump C27 discharges the liquid drawn from the other nasal cavity into the waste tank 5 through the first discharge line 3.

[0110] In circulation mode, the flushing pump D26 draws the second liquid through the second liquid supply line 6 and supplies it into one nasal cavity, while the suction pump C27 discharges the liquid drawn from the other nasal cavity through the second discharge line 7 to the circulation tank 8.

[0111] The nasal irrigation circulation system provided in this application also includes a first nozzle cannula 31 and a second nozzle cannula 32. Both nozzle cannulas can be disposable nasal contact nozzle cannulas.

[0113] The input end of the suction pump 2 draws liquid into the other nasal cavity through the second nozzle cannula 32.

[0114] When the first nozzle insertion tube 31 and the second nozzle insertion tube 32 described above are used in Embodiments 1 to 4, they can be configured as follows:

[0115] Reference Figure 1In the nasal irrigation circulation system provided in Embodiment 1, the output end of the irrigation pump 1 is connected to the first nozzle cannula 31 for supplying liquid to one nasal cavity; the input end of the suction pump 2 is connected to the second nozzle cannula 32 for extracting liquid to the other nasal cavity.

[0116] Reference Figure 2 In the nasal irrigation circulation system provided in Embodiment 2, the output ends of irrigation pump A15 and irrigation pump B16 are connected to the third three-way structure 17 via a pipeline. The output end of the third three-way structure 17 is connected to the first nozzle insertion tube 31 for supplying liquid to one nasal cavity. The input end of suction pump 2 is connected to the second nozzle insertion tube 32 for extracting liquid to the other nasal cavity. In addition, a one-way valve is installed on the pipeline between the output ends of irrigation pump A15 and irrigation pump B16, and a one-way valve can also be installed between the input end of suction pump 2 and the second nozzle insertion tube 32 to prevent backflow of liquid.

[0119] In summary, the nasal irrigation and circulation system provided in this application allows for switching between irrigation and circulation modes. After the disposable nasal nozzle cannula seals into the nostril without repeated insertion and removal, before administering medication for nasal circulation, an independent irrigation mode is used to rinse with a primary liquid (physiological saline) to thoroughly remove nasal pathogens before starting the circulation mode, i.e., nasal medication circulation therapy. This addresses the issue of incomplete disinfection of the tubing after patients use the circulation device, where excessive nasal secretions and pathogens easily adhere to the tubing.
