Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a flushing connector with flow monitoring and a nasal care device. Background Technology

[0002] Nasal irrigators are a commonly used nasal care device. With the technological advancements of recent years, some innovative desktop models have been widely used in wards and outpatient treatments. These devices consist of a main unit that provides power and fluid storage, and a connector that is inserted into the patient's nasal cavity and nostrils. There are flexible tubing of varying lengths connecting the main unit and the connector. Treatment staff should first ensure that the connector is securely connected to the patient's nostrils before turning on the main unit to operate the nasal irrigation treatment.

[0003] Because of the flexible tubing connection between the connector and the main unit, the position of the patient's nostril connector relative to the main unit's tubing interface is freely variable. With the treatment table and chair relatively fixed, due to differences in patient height, or changes in posture such as transitioning from sitting to standing, or from standing to prone on the table where the main unit is located, the difference between the height of the pump body (which provides the nasal irrigation fluid) relative to the ground and the height of the nostril relative to the ground is uncertain. If the pump's output power is fixed, then during operation at the same power level, the greater the height difference between the nostril and the pump body, the more effectively the fluid is pumped. The lower the flow rate into the nasal cavity, the smaller the flow rate per unit time. Conversely, the smaller the height difference between the nostrils and the pump body, the higher the flow rate of the liquid into the nasal cavity, and the larger the flow rate per unit time. Therefore, for the same person using the same equipment, changes in body position during treatment will lead to changes in the flow rate of the liquid entering the nasal cavity. These changes can cause irritation to the nasal cavity, resulting in extreme discomfort for the patient and thus interrupting the treatment. Alternatively, the flow rate may be maximized momentarily due to a decrease in the patient's body position, such as lying down, which can cause strong damage to the nasal mucosa and compromise the patient's treatment safety. Utility Model Content

[0004] The purpose of this invention is to provide a flushing connector and nasal care device with flow monitoring, in order to solve the problem that existing nasal care devices cannot detect flow, and therefore cannot adjust the flow of liquid entering the nasal cavity according to changes in the user's body position.

[0005] In view of the above objectives, in a first aspect, this application provides a flushing connector with flow monitoring, comprising: a housing, and a liquid supply line, a liquid extraction line, a first liquid flow detector, a second liquid flow detector and a control circuit board disposed in the housing;

[0006] The fluid supply line is used to deliver fluid into one nasal cavity, while the fluid aspiration line is used to deliver fluid drawn out through the other nasal cavity.

[0007] The first liquid flow detector is connected to the liquid supply pipeline and is used to detect the first liquid flow value in the liquid supply pipeline.

[0008] The second liquid flow detector is connected to the liquid extraction pipeline and is used to detect the second liquid flow rate value in the liquid extraction pipeline;

[0009] The control circuit board is electrically connected to the first liquid flow detector and the second liquid flow detector, respectively, and is used to collect the first liquid flow value and the second liquid flow value and convert them into electrical signals to be transmitted to the host.

[0010] Furthermore, the interior of the housing is provided with a cavity for accommodating the liquid supply line, the liquid extraction line, the first liquid flow detector, the second liquid flow detector, and the control circuit board;

[0011] The upper part of the housing is provided with a first interface and a second interface, wherein the liquid supply pipeline is connected to the first interface and the liquid extraction pipeline is connected to the second interface.

[0012] Furthermore, the housing is provided with a pipeline channel inside, which is located below and communicates with the receiving cavity. The pipeline channel is used to accommodate the liquid supply pipeline, the liquid extraction pipeline, and the circuit board of the control circuit board.

[0013] Furthermore, it also includes a flexible pipeline, one end of which is used to connect to the pipeline channel and the other end is used to connect to the main unit of the equipment. The liquid supply pipeline, the liquid extraction pipeline and the circuit board of the control circuit board are respectively placed inside the flexible pipeline.

[0014] Furthermore, the control circuit board is located between the liquid supply line and the liquid extraction line.

[0015] Furthermore, it also includes a flushing nozzle, which is connected to the first interface.

[0016] Furthermore, it also includes a suction nozzle, which is connected to the second interface.

[0017] Furthermore, the rinsing nozzle and the suction nozzle are made of a single piece of soft rubber.

[0018] Secondly, this application provides a nasal care device, including a main unit and the aforementioned flushing connector with flow monitoring.

[0019] The device host is equipped with a host circuit board and a flushing pump and a suction pump electrically connected to the host circuit board. The device host is equipped with a combination interface on the outside, which is divided into: a first interface connected to the flushing pump, a second interface connected to the suction pump, and an electrical interface electrically connected to the host circuit board.

[0021] The suction nozzle's suction line is connected to the second interface;

[0022] The end connectors of the circuits on the control circuit board are connected to the electrical interface.

[0023] Furthermore, the main circuit board is used to adjust the output power of the flushing pump and the suction pump respectively according to the received electrical signals of the first liquid flow rate value and the second liquid flow rate value, so that the first liquid flow rate value and the second liquid flow rate value are kept within a preset value range.

[0024] By adopting the above technical solution, the flushing connector with flow monitoring provided in this application has the following technical advantages compared with the prior art:

[0025] In this design, a fluid supply line delivers fluid into one nasal cavity, while a suction line delivers fluid extracted from the other nasal cavity. A first fluid flow detector, connected to the supply line, detects the first fluid flow rate. A second fluid flow detector, connected to the suction line, detects the second fluid flow rate. A control circuit board collects the first and second fluid flow rates and converts them into electrical signals, which are then transmitted to the main unit. During use, the two detectors monitor changes in nasal fluid flow rate in real time. The control circuit board transmits these signals to the main unit, which allows for adjustment of the fluid flow rate, effectively mitigating the adverse effects of changes in the patient's nostril position relative to the main unit.
