Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and more specifically, to a high-flow oxygen inhalation device with nebulization function. Background Technology
[0002] A high-flow-rate oxygen (HFORO) device is a medical device that provides a high flow rate of oxygen and is commonly used to treat various respiratory diseases. This device is characterized by its ability to provide a warm, moist air-oxygen mixture, to offer different concentrations of oxygen, even pure oxygen, and to deliver a high flow rate exceeding 60 L / min. It provides the same non-invasive CPAP effect as 6 cmH2O, flushing out the physiological dead space in the airway and slightly improving carbon dioxide retention.
[0003] High-flow oxygen therapy devices are mainly used in clinical treatment of patients with respiratory diseases, such as acute respiratory distress syndrome, acute respiratory failure, and chronic obstructive pulmonary disease. High-flow oxygen therapy devices can provide patients with a large amount of oxygen, so that patients can receive sufficient oxygen support and relieve breathing difficulties.
[0004] However, most high-flow oxygen therapy devices deliver oxygen directly into the nasal cavity through a tube, making it inconvenient for patients with rhinitis to inhale. Furthermore, prolonged high-speed oxygen delivery can cause discomfort and pressure sores on the nasal cavity walls. Additionally, traditional high-flow oxygen therapy devices cannot provide nebulized medication during oxygen delivery, further complicating their use.
[0005] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content
[0006] The purpose of this invention is to provide a high-flow oxygen inhalation device with nebulization function, which improves comfort and enhances oxygen inhalation effect, further realizing nebulized drug therapy.
[0007] This utility model provides a high-flow oxygen inhalation device with nebulization function, including a main unit. The high-flow oxygen inhalation device also includes a mask assembly, a high-flow nasal cannula assembly, and a nebulization drug delivery assembly. The mask assembly includes a main mask and a sealing pad. The main mask is hollow inside with an opening at the rear end. Two nasal cannula insertion ports are provided at the front of the main mask. A sealing pad is provided at the edge of the rear opening of the main mask, and installation notches are provided on both sides of the sealing pad. The high-flow nasal cannula assembly includes an elastic band, a high-flow nasal tube, and a connecting part. The two ends of the elastic band are provided with... The surgical patch has a connecting part fixedly connected to the middle of the front of the elastic bandage; two high-flow nasal cannulas are connected to the side of the connecting part; a connecting hole is provided on the top of the connecting part; the connecting hole is connected to the nebulizer drug delivery assembly through a conduit; the nebulizer drug delivery assembly and the high-flow nasal cannulas are in communication; the other end of the nebulizer drug delivery assembly is connected to the main unit through a connecting tube; both ends of the elastic bandage pass through the mounting notches on both sides of the sealing pad; the elastic bandage is wrapped around the front of the main body mask; and the two high-flow nasal cannulas are inserted into the two nasal cannula insertion ports respectively.
[0008] Using the above technical solution, the main mask is placed over the patient's face and secured with elastic straps and Velcro; a sealing pad adheres to the patient's face, improving comfort and sealing; the main unit provides a humidified air-oxygen mixture or oxygen of different concentrations; the combination of the main mask and a high-flow nasal cannula solves the technical problems of direct insertion of the high-flow nasal cannula into the patient's nasal cavity, causing discomfort and making it difficult for rhinitis patients to inhale oxygen, thus improving comfort and enhancing oxygenation effect; in addition, the nebulizer dispensing component contains therapeutic medication, and the air inlet tube at the lower end of the nebulizer dispensing component is connected to the main unit via a connecting tube, further realizing nebulized drug therapy while supplying oxygen.
[0009] Further, the nebulizing dosing assembly includes an upper cup body, a lower cup body, a connecting sleeve, an air inlet tube, an inhalation tube, a connecting rod, an arc-shaped baffle, and a cross-shaped bracket; the upper cup body is a hollow cylinder with an air outlet on its upper surface, the air outlet being connected to the connecting hole via a conduit; the cross-shaped bracket is connected to the air outlet, the lower end of the cross-shaped bracket is vertically connected to the connecting rod, and the other end of the connecting rod is connected to the arc-shaped baffle; the lower end of the upper cup body... The upper end is provided with a connecting sleeve. The lower end cup body is a cylinder with an open upper end and a hollow interior. The connecting sleeve is inserted into the upper opening of the lower end cup body. The lower end face of the upper end cup body is provided with an insertion port. The air intake pipe passes through the bottom surface of the lower end cup body. The head of the air intake pipe passes through the insertion port.

The required medication is added inside the lower cup, and then the cup body and cup cover are tightened. The main unit injects oxygen into the air inlet tube. The rapidly flowing oxygen enters the air inlet tube. According to the Venturi principle, the liquid inside the lower cup flows into the air inlet tube through the inhalation tube and is sprayed out from the small air jet at the head of the air inlet tube, hitting the arc-shaped baffle and forming mist-like particles. These particles are discharged from both sides of the arc-shaped baffle, i.e., inside the upper cup, and flow towards the air outlet. They then enter the nasal cannula through the conduit and enter the main mask for nebulization treatment.

Furthermore, the nebulization drug delivery component contains therapeutic medication, and the air inlet pipe at the lower end of the nebulization drug delivery component is connected to the main unit via a connecting pipe, further enabling nebulized drug therapy while supplying oxygen.
