Description

Technical Field

[0001] The utility model relates to the technical field related to medical devices, and in particular to an adjustable head fixing belt structure of an oxygen therapy device. Background Art

[0002] Nasal high-flow humidified oxygen therapy equipment is mainly used for patients with spontaneous breathing, and is suitable for patients with mild to moderate dyspnea and respiratory distress caused by various diseases or accompanied by hypoxemia;

[0003] When in use, the patient connects one end of the nasal cannula to the oxygen supply device and the other end to the oxygen supply mask. The oxygen supply mask is fixed to the patient's head through a fixing belt. Then, under the action of the continuous high-flow breathing gas output by the oxygen supply device, continuous positive airway pressure can be generated to prevent alveolar shrinkage and collapse. For agitated patients, when the above structure is used for oxygen supply, if the patient's head cannot be fixed during oxygen inhalation, the nasal cannula may be easily dislocated.

[0004] Therefore, based on the above problems, the present invention provides an adjustable head fixing belt structure of an oxygen therapy device. Utility Model Content

The two oxygen supply tubes 2 are connected to the mounting plate 3 via two snap-fit ​​components 7.

[0030] The matching adjustment component 11 includes a driving motor 115, the model of the driving motor 115 is VYF-02, and a meshing gear 113 is fixed on the power output end of the driving motor 115. Both sides of the meshing gear 113 are meshed with rack plates 112, and the ends of the two rack plates 112 that are separated from each other are fixed with fixed blocks 114, and each fixed block 114 is movably hinged with a double connecting rod 111 between the corresponding arc-shaped side support plate 9. A rectangular through hole is opened on the mounting plate 3, and the driving motor 115 is installed in the rectangular through hole, and the opposite ends of the two rack plates 112 are both penetrated and slidably arranged on the mounting plate 3.

[0031] During specific use, when oxygen therapy is needed, the patient's head is fixed by supporting the patient's chin through the arc-shaped bottom support plate 4, adjusting according to the size of the patient's head, starting the drive motor 115, and driving the meshing gear 113 to rotate under the power output of the drive motor 115.

Two clamping grooves 72 are provided on the matching plate 73, and the two clamping grooves 72 are staggered. The clamping grooves 72 are arranged in a U shape.

[0037] In specific use, based on the first embodiment, the oxygen supply tube 2 is adjusted and fixed according to the oxygen inhalation requirements of different patients, and the operation is as follows:

[0038] When the oxygen supply tube 2 needs to be adjusted, the oxygen supply tube 2 is moved along the corresponding connecting hole. When it is moved to the required length, it is fixed. By rotating the fixing bolt 71, the fixing bolt 71 is driven to rotate along the mounting plate 3, thereby driving the two engaging grooves 72 on the mounting plate 3 to move. Since the two engaging grooves 72 are staggered, it is convenient to fix the adjusted oxygen supply tube 2, which is convenient for the subsequent oxygen inhalation operation.
