Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, specifically to a nasal positive pressure ventilation device that reduces the pressure on patients. Background Technology

[0002] With the development of technology and the continuous development of industry, the air quality on which people depend for survival is gradually declining. As a result, the number of patients with respiratory infections is constantly increasing. Treatment for respiratory patients involves the use of medical supplies such as ventilation devices or nasal masks. Continuous positive pressure ventilation devices should have a good seal and a stable and reliable fixation method when in contact with the patient's nose, and should also have a gentle contact characteristic; otherwise, it will cause discomfort to the patient. This is especially important when the patient is an infant or even a premature baby, whose skin is delicate.

[0003] Existing methods for tracheal oxygen delivery use nasal cannulas. For example, application number 202420427548.3 describes an oxygen delivery nasal cannula with an anti-dislodgement structure. In use, the nasal plug needs to be inserted into the nasal cavity, and a strap is inserted through the structure and then tied to the head. This method of fixation helps the nasal mask to make closer contact with the face and bridge of the nose, achieving a good seal. However, both the contact with the nasal cavity and the close contact between the strap and the face may cause discomfort for some patients with sensitive skin. Currently, a more comfortable fixation method is the nasal mask structure shown in application number 201420742933.3, which uses a universal flexible tube for fixation. Although theoretically the universal flexible tube has good plasticity—meaning it can be stretched to a fixed shape and held in place by hand—in actual use, it usually has some springback. This can prevent the nasal mask from achieving a good seal with the patient's nasal cavity. Application number 200680051620.1 describes a nasal mask and generator body that are typically interference-fitted or glued together. The problem with this is that the interference fit is often difficult to control. Too little interference results in a loose connection and air leakage, while too much interference makes installation difficult. Using glue for bonding significantly limits its clinical application. Different patients have different facial features and nasal sizes, leading to variations in the nasal mask that fits them, and glued nasal masks are difficult to replace.

[0004] To address the shortcomings of the existing technologies, a new solution is proposed, aiming to provide a solution that is gentle on the patient's face, offers various fixation methods, and allows for convenient and reliable connection between the nasal mask and the generator body. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a nasal positive pressure ventilation device with a simple structure that prevents it from falling off.

[0006] To solve the above-mentioned existing technical problems, the present invention adopts the following solution: a nasal positive pressure ventilation device, including a nasal mask connecting seat and an air tube, wherein the nasal mask connecting seat is formed by splicing connecting seat A and connecting seat B, and an air tube is sleeved on both connecting seat A and connecting seat B.

[0007] Preferably, the outer ring of the nose mask connector is provided with an inverted buckle.

[0008] Preferably, the connecting seat A is provided with a plurality of connecting shafts, and the surface of the connecting seat A is provided with an outer stepped groove.

[0009] Preferably, the connector B has several connecting holes and an inner stepped groove is provided on the surface of the connector B.

[0010] Preferably, the back of the nose mask connector is provided with several fixed corners, and a limiting block is provided on the inner side of the fixed corner, forming an anti-detachment structure between the fixed corner and the limiting block.

[0011] Preferably, the nose mask connector is equipped with a nose mask body, the nose mask body is provided with straps, and the straps are provided with nose mask thread holes on both sides.

[0012] Preferably, the nose mask body has a recessed annular groove.

[0013] This utility model provides a nasal positive pressure ventilation device using the above-mentioned technical solution. Through optimized adjustment structure design, it facilitates quick assembly and disassembly, reduces the risk of infection, and has the following advantages compared with the prior art: 1. The nasal mask and the nasal mask connector are respectively equipped with a nasal mask threading hole and a fixing angle. The nasal mask can be fixed to achieve a better seal, while the nasal mask connector can be fixed to improve the patient's facial comfort and improve the adaptability of the nasal positive pressure ventilation device to the patient.

[0014] 2. The nasal mask and nasal mask connector are respectively equipped with concave ring grooves and buckles, which makes the fixation more secure and also allows for easy replacement of different models of nasal masks. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the structure of this utility model. Figure 2 This is a structural diagram of the back of the present invention. Figure 3 This is a partial schematic diagram of the connector A of this utility model. Figure 4 This is a partial schematic diagram of the connector B of this utility model. Figure 5 This is a partial schematic diagram of the nose mask body of this utility model.

[0016] In the figure, the components are: 1. Nasal mask connector; 2. Trachea; 3. Connector A; 4. Connector B; 5. Inverted buckle; 6. Connecting shaft; 7. Outer step groove; 8. Connecting hole; 9. Inner step groove; 10. Fixing angle; 11. Limiting block; 12. Nasal mask body; 13. Strap; 14. Nasal mask threading hole; 15. Recessed ring groove. Detailed Implementation like Figures 1 to 5 As shown, a nasal positive pressure ventilation device includes a nasal mask connector 1 and an airway 2. The nasal mask connector 1 is formed by splicing a connector A3 and a connector B4. An airway 2 is fitted onto both connector A3 and connector B4. The outer ring of the nasal mask connector 1 is provided with a buckle 5. The connector A3 is provided with several connecting shafts 6. The surface of the connector A3 is provided with an outer stepped groove 7. The connector B4 is provided with several connecting holes 8. The surface of the connector B4 is provided with an inner stepped groove 9. The back of the nasal mask connector 1 is provided with several fixing angles 10. The inner side of the fixing angles 10 is provided with a limiting block 11. An anti-detachment structure is formed between the fixing angles 10 and the limiting block 11. A nasal mask body 12 is installed on the nasal mask connector 1. The nasal mask body 12 is provided with a strap 13. The strap 13 is provided with nasal mask thread holes 14 on both sides. The nasal mask body 12 is provided with a concave annular groove 15.

[0017] In actual operation, several connecting shafts 6 are provided inside the connecting seat A3. The connecting seat A3 is connected and fixed to the connecting holes 8 on the connecting seat B4 through the connecting shafts 6, and the outer stepped groove 7 and the inner stepped groove 9 are fitted together to form the nose mask connecting seat 1. An inverted buckle 5 is provided on the outside of the nose mask connecting seat 1. The nose mask body 12 is installed and connected to the nose mask connecting seat 1, so that the concave annular groove 15 in the nose mask body 12 is fastened on the inverted buckle 5, which increases the stability of the nose mask body 12 installation. A strap 13 is installed on the nose mask body 12, and nose mask threading holes 1 are provided on both sides of the strap 13. 4. When using, place the nasal mask body 12 on the patient's face, pass the strip through the nasal mask threading hole 14 and then around the patient's head or neck for fixation. Then pass the strip through the fixing corner 10 on the back of the nasal mask connector 1 and similarly around the patient's head or neck for fixation. Since the nasal mask body 12 is made of silicone, it will fit snugly against the patient's face. Through the installation method of the nasal mask threading hole 14 and the fixing corner 10, a certain distance can be created between the strip and the patient's face, so that the strip will not directly contact the patient's face and avoid discomfort to the patient.
