Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments.

If the specific posture changes, the directional indications will also change accordingly.

[0028] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0029] Oxygen therapy involves inserting specially designed bilateral nasal cannulas into both nostrils to inhale oxygen. Its main function is to increase arterial oxygen partial pressure, improve the body's oxygen supply, and reduce the respiratory and circulatory burden caused by compensatory hypoxia.

[0030] In related technologies, existing oxygen delivery devices have low oxygen utilization rates. Due to the cumbersome methods of adjusting oxygen flow and disassembly, a large amount of oxygen is wasted or the desired breathing effect cannot be achieved.

[0031] To address some of the problems in related technologies, this application provides an adjustable flow oxygen delivery device. When the flow rate of the oxygen delivery pipe 12 needs to be adjusted, simply install the first limiting ring 14 and the second limiting ring 15 on the outer wall of the oxygen delivery pipe 12, and then insert the baffle 161 into the inner side of the clamping block 17. This allows the two sets of limiting rings to be installed on the outer wall of the oxygen delivery pipe 12. Rotating the screw 18 causes the pressure block 181, which is threaded to it, to descend, thereby squeezing the oxygen delivery pipe 12. Then, the operator controls the flow rate according to the position of the slide rod 19. This device has a simple structure, facilitates the adjustment of the flow rate of the oxygen delivery pipe 12, and also makes it easy to disassemble the adjustment mechanism, making it more convenient to use and increasing work efficiency.

[0032] This application is described below with reference to the accompanying drawings and specific embodiments:

[0033] Combination Figures 1-3 This application provides an adjustable flow oxygen delivery device, including an adjustment component 1. The adjustment component 1 includes: an oxygen delivery mechanism 11 with an oxygen delivery tube 12 disposed on its outer side; an oxygen delivery mask 13 disposed on the oxygen delivery tube 12; a first limiting ring 14 disposed on the outer side of the oxygen delivery tube 12; a second limiting ring 15 disposed on the outer side of the oxygen delivery tube 12 and connected to the first limiting ring 14 via a hinge; a fixing rod 16 disposed on the second limiting ring 15; a baffle 161 disposed on the outer side of the fixing rod 16; a locking block 17 disposed on the first limiting ring 14; a lead screw 18 rotatably disposed on the first limiting ring 14 and the second limiting ring 15 respectively; a pressure block 181 threadedly disposed on the outer side of the lead screw 18; a sliding rod 19 symmetrically disposed on the pressure block 181; and sliding grooves 191 symmetrically opened on the first limiting ring 14 and the second limiting ring 15 respectively.

[0034] When it is necessary to adjust the flow rate of the oxygen delivery tube 12, firstly, place the limiting ring 14 and the limiting ring 15 on the outer wall of the oxygen delivery tube 12. Since the limiting ring 14 and the limiting ring 15 are connected by a hinge, rotate the baffle 161, which is rotatably connected to the fixing rod 16, so that it inserts into the inner side of the locking block 17 set on one side of the limiting ring 14. The baffle 161 is locked into the inner side of the locking block 17 by friction. In this way, the two sets of limiting rings can be installed on the outer wall of the oxygen delivery tube 12. Then, rotate the screw 18, which is rotatably connected to the limiting rings. The screw 18 can drive the pressure block 181, which is threaded to it, to descend, thereby... The oxygen delivery tube 12 is squeezed, and the position of the pressure block 181 is determined according to the position of the slide rod 19 inside the slide groove 191. Then, the operator controls the flow rate according to the position of the slide rod 19. After adjustment, the oxygen mask 13 is put on the patient's face, and then the oxygen delivery mechanism 11 is used to deliver oxygen to the patient. The device has a simple structure, which makes it easy to adjust the flow rate of the oxygen delivery tube 12. It is also easy to disassemble the adjustment mechanism, making it more convenient to use and increasing work efficiency. The working principle of the oxygen delivery mechanism 11 is common knowledge and will not be described in detail here.

[0035] In some embodiments, an auxiliary component 2 is provided on the first limiting ring 14, the auxiliary component 2 including magnets 21 respectively disposed on the first limiting ring 14 and the second limiting ring 15.

[0036] Magnets 21 are installed inside the first limiting ring 14 and the second limiting ring 15 respectively. When the first limiting ring 14 and the second limiting ring 15 are closed, the two sets of magnets 21 can be used to limit the first limiting ring 14 and the second limiting ring 15 to a certain position, so as to facilitate subsequent operations and increase work efficiency.

[0037] In some embodiments, the auxiliary component 2 further includes: scales 22 symmetrically arranged on the slide groove 191.

[0038] The scale 22 is symmetrically set on both sides of the chute 191, so that the operator can adjust the position of the pressure block 181 according to the scale 22, so as to adjust the flow rate of the oxygen delivery tube 12 more precisely and make it more convenient to use.

[0039] In some embodiments, the slide bar 19 is a screw.

[0040] The slide bar 19 is set as a screw and threadedly connected to the pressure block 181. This makes it easy to disassemble and replace the slide bar 19 when it is damaged in the future. At the same time, since the pressure block 181 does not have a limiting mechanism after the slide bar 19 is disassembled, it can be taken out from the inside of the limiting ring for maintenance.

[0041] In some embodiments, the auxiliary component 2 further includes an anti-slip pad 23 disposed on the inner side of the card block 17.

[0042] An anti-slip pad 23 is provided on the inner side of the locking block 17. When the baffle 161 is locked on the inner side of the locking block 17, the anti-slip pad 23 can increase the friction and make the connection between the baffle 161 and the locking block 17 more stable.

[0043] In some embodiments, the fixing rod 16 is connected to the limiting ring 15 by bolts.

[0044] The fixing rod 16 and the limiting ring 15 are bolted together. This way, when the baffle 161 on the outer wall of the fixing rod 16 is damaged, the fixing rod 16 can be removed and replaced to avoid affecting subsequent use.

[0045] In some embodiments, the auxiliary component 2 further includes rubber pads 24 disposed inside the first limiting ring 14 and the second limiting ring 15, respectively.

[0046] Rubber pads are installed on the inner sides of limiting ring 14 and limiting ring 15 respectively. This increases the friction between the limiting rings and the oxygen supply pipe 12, making the connection between the limiting rings and the oxygen supply pipe 12 more stable. This prevents the limiting rings installed on the outer wall of the oxygen supply pipe 12 from moving during use, thus increasing the structural stability of the device.

[0047] In some embodiments, the auxiliary component 2 further includes pulleys 25 symmetrically arranged on the pressure block 181.

[0048] Pulleys 25 are symmetrically arranged on both sides of the pressure block 181. When the pressure block 181 moves, the pulleys 25 can slide, which can reduce the friction between the pressure block 181 and the limiting ring, making the movement of the pressure block 181 more stable.
