Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to an oxygen inhalation device with a dustproof protective cover. Background Art

[0002] An oxygen inhalation device is a combination of medical devices used to provide oxygen to patients. It primarily consists of an oxygen source (e.g., oxygen cylinder, oxygen concentrator, etc.), oxygen delivery tubing (e.g., nasal cannula, mask connection tube, etc.), and an oxygen regulator (e.g., flow control valve, etc.).

[0003] However, most of the oxygen inhalation devices on the market now have dust-proof protective covers. However, the current protective covers are generally composed of the airway tube and the mask directly, and their functions are relatively simple. They cannot adjust the size of the air flow of the airway tube. Different patients have different requirements for the inhaled oxygen flow rate. For this reason, we propose an oxygen inhalation device with a dust-proof protective cover. Utility Model Content

[0004] The purpose of the present utility model is to provide an oxygen inhalation device with a dustproof protective cover to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an oxygen inhalation device with a dustproof protective cover, comprising an oxygen inhalation device body and a breathing mask, an air guide tube being embedded on one side of the top of the oxygen inhalation device body, a connecting ring being fixedly connected to the outer surface of the arc-shaped end of the breathing mask, and the connecting ring being fixedly connected to one end of the air guide tube, a through groove being penetrated inside the connecting ring, an accommodating cavity being provided inside the connecting ring at the upper end of the through groove, a worm being rotatably connected to both sides of the inner wall of the accommodating cavity, and the worm extending through the side wall of the connecting ring to the outer end, a rotating rod being rotatably connected to the upper and lower inner walls of the through groove, and the top end of the rotating rod extending through the through groove into the interior of the accommodating cavity, a worm gear being fixedly connected to the top of one end of the rotating rod, and the worm gear being meshed with the worm gear, and the rod wall of the rotating rod being fixedly connected to a circular baffle arranged inside the through groove.

[0006] Preferably, an elastic band is fixedly connected between the edges on both sides of the opening end of the breathing mask.

[0007] Preferably, a plurality of air outlet holes are provided on both sides of the arc-shaped end of the breathing mask.

[0008] Preferably, a handle is fixedly connected to the top of one end of the worm, and a plurality of grooves are provided on the arc-shaped surface of the handle.

[0009] Preferably, the inner diameter of the air guide pipe and the through groove is adapted to the outer diameter of the baffle.

[0010] Compared with the prior art, the beneficial effects of the present invention are: first, the handle is rotated to drive the worm to rotate, and then through the arrangement of the worm gear, the rotating rod, the baffle, and the through slot, the rotation angle of the baffle inside the through slot can be adjusted, and then the size of the airflow rate can be controlled to adapt to different patients, thereby improving the practicality of the device.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1-4 The utility model provides a technical solution: an oxygen breathing device with a dust-proof protective cover, comprising an oxygen breathing device body 1 and a breathing mask 2, an air guide tube 11 is embedded on one side of the top of the oxygen breathing device body 1, and a connecting ring 3 is fixedly connected to the outer surface of the arc end of the breathing mask 2, and the connecting ring 3 is fixedly connected to one end of the air guide tube 11. A through groove 301 is formed inside the connecting ring 3, and an accommodating cavity 302 is formed inside the connecting ring 3 at the upper end of the through groove 301. Both sides of the inner wall of the accommodating cavity 302 are rotatably connected to a worm gear 31, and the worm gear 31 penetrates the side wall of the connecting ring 3 and extends to the outer end. The upper and lower inner walls of the through groove 301 are rotatably connected to a rotating rod 4, and the top end of the rotating rod 4 penetrates the through groove 301 and extends into the accommodating cavity 302. The top of one end of the rotating rod 4 is fixedly connected to a worm gear 41, and the worm gear 41 is meshed with the worm 31, and the rod wall of the rotating rod 4 is fixedly connected to a circular baffle 42 arranged inside the through groove 301.

[0018] Furthermore, an elastic band 21 is fixedly connected between the edges on both sides of the opening end of the breathing mask 2, and the breathing mask 2 can be tied to the head through the elastic band 21.

[0019] Furthermore, a plurality of air outlet holes 22 are provided on both sides of the arc-shaped end of the breathing mask 2 , and the patient can exhale carbon dioxide through the plurality of air outlet holes 22 .

[0020] Furthermore, a handle 32 is fixedly connected to the top of one end of the worm 31 , and a plurality of grooves 33 are provided on the arc-shaped surface of the handle 32 . The plurality of grooves 33 can increase the friction of the handle 32 .

[0021] Furthermore, the inner diameters of the air guide tube 11 and the through slot 301 are matched with the outer diameter of the baffle 42 , and the baffle 42 can rotate in the through slot 301 to adjust the size of the airflow.

[0022] Specifically, when using the present invention, the patient can first tie the breathing mask 2 to the head through the elastic band 21, and then start the oxygen inhalation device body 1 to supply air to the airway tube 11.
