Description

Technical Field

[0001] The utility model relates to the field of oxygen pillows, and particularly relates to a double-joint oxygen pillow. Background Art

[0002] In the design and application fields of traditional oxygen pillows, there are obvious limitations, especially in the mixed use of oxygen filling and oxygen supply functions, inconvenient adjustment of oxygen supply speed, poor connection and sealing performance, and lack of an effective pressure maintaining mechanism. Most traditional oxygen pillows adopt a single oxygen filling / supply interface, which not only reduces the efficiency of the oxygen filling and supply processes, but also reduces the utilization efficiency and safety of oxygen due to the inability to effectively prevent oxygen leakage after oxygen filling, posing potential risks to patients and medical staff. In terms of adjusting the oxygen supply speed, existing oxygen pillows often lack flexibility, using fixed flow rates or manual control methods, and are unable to finely adjust according to the actual needs of patients, restricting the scope of application and use effect of the oxygen pillow, especially in medical scenarios where precise control of the oxygen supply volume is required.

[0003] In addition, the connection method between the oxygen delivery tube and the gas storage pillow of traditional oxygen pillows is simple, lacking effective sealing and rotation mechanisms, resulting in frequent problems of oxygen leakage and pipeline entanglement during use, reducing the use safety and convenience, and increasing the operation burden of medical staff. Finally, traditional oxygen pillows often rely on manual pressing or external pressure sources to ensure the oxygen supply pressure before use, which is inconvenient and inefficient to operate. Especially in emergency situations, this manual-dependent operation method may delay treatment and pose a threat to the life safety of patients.

[0004] In view of the above limitations, there is an urgent need to innovate the design of oxygen pillows to improve their use efficiency, safety, operation convenience, and stability. To address these needs, this patent proposes a double-joint oxygen pillow, which solves the problems existing in traditional oxygen pillows through innovative design, realizes the efficient separation of oxygen filling and oxygen supply, flexible adjustment of oxygen supply speed, optimization of connection and sealing performance, and introduction of an internal pressure maintaining mechanism, significantly improving the use efficiency, safety, operation convenience, and stability of the oxygen pillow, and providing a more efficient and safe oxygen supply solution for medical, first aid, and other scenarios.

After filling oxygen, the gas supply and oxygen delivery pipe 2 can prevent the internal oxygen from flowing out of the air storage pillow 1 through the oxygen delivery head 3, and can export the oxygen through the oxygen supply side pipe 4 for the patient to use. Moreover, the gas supply and oxygen delivery pipe 2 can limit the supply flow rate of oxygen through the flow - limiting clip 28, so that the oxygen pillow can be used for oxygen filling and oxygen supply respectively through the double - joint, making the use of the oxygen pillow more convenient.

[0040] Preferably, a plurality of internally hollow extrusion through holes 23 penetrate through the upper and lower parts of the storage pillow 1, and the plurality of extrusion through holes 23 are all connected to the outer walls of the upper and lower ends of the storage pillow 1. A plurality of elastic extrusion ropes 24 penetrate through the plurality of extrusion through holes 23, and the plurality of extrusion ropes 24 are evenly distributed left and right inside the plurality of extrusion through holes 23.

A plurality of elastic teeth 27 are fixedly connected to the inner wall of the limiting snap ring 26, and the plurality of elastic teeth 27 are all located outside the squeezing pull rope 24. Since one end of the squeezing pull rope 24 is fixedly connected with the squeezing limiting ring 25 and the other end is provided with the limiting snap ring 26, and the squeezing limiting ring 25 cannot pass through the inside of the squeezing through hole 23, the squeezing pull rope 24 can be tightened inside the plurality of squeezing through holes 23, so as to squeeze the oxygen pillow. At the same time, the other end of the squeezing pull rope 24 can be fixed in position through the plurality of elastic teeth 27 arranged inside the limiting snap ring 26. Since the plurality of elastic teeth 27 are arranged in an arc shape and the end close to the squeezing pull rope 24 is arranged in an arc surface, when the squeezing pull rope 24 is pulled upward, it can slide between the plurality of elastic teeth 27. When the squeezing pull rope 24 is released, the squeezing pull rope 24 slides downward under the action of elasticity. At this time, the upper ends of the elastic teeth 27 will deform toward the middle under the drive of the outer wall of the squeezing pull rope 24, so as to form a squeeze on the squeezing pull rope 24, and further fix the position of the squeezing pull rope 24.
