[0002] Oxygen inhalation is a commonly used clinical treatment method, mainly used to relieve hypoxia, correct arterial oxygen deficiency, promote metabolism. Appropriate oxygen inhalation helps to increase the partial pressure of oxygen and oxygen saturation, and assist in the treatment of various diseases, such as respiratory failure, chronic bronchitis, cerebrovascular diseases, coronary heart disease, etc. Even if the symptoms are not obvious, hypoxia or oxygen debt may still exist, and oxygen inhalation is often required before and after surgery, in cases of massive hemorrhage shock, fetal monitoring, etc.

[0003] Chinese Patent with the patent publication number CN219921788U discloses a medical oxygen humidifying inhalation device, which relates to the technical field of oxygen inhalation devices, including a protective shell. The inner surface of the protective shell is slidably connected with a tank body. A chute is provided on the inner side surface of the protective shell. A slider is fixedly connected to the outer surface of the tank body. The slider is slidably connected to the surface of the chute. A second fixing port is provided on the upper surface of the protective shell. An oxygen outlet pipe is arranged on the surface of the second fixing port. A second plastic telescopic pipe is arranged on the lower surface of the oxygen outlet pipe. The other end of the second plastic telescopic pipe is arranged inside the tank body. One end of the oxygen outlet pipe away from the second fixing port is provided with an oxygen inhalation mask. A cavity is provided on the inner wall of the outer surface of the protective shell, and the surface of the cavity is filled with sound insulation cotton. Through the setting of the first spring, micro switch, top block and signal transmission module, the purpose of improving the practicability of the device is achieved. Through the setting of the sound insulation cotton, the purpose of improving the comfort of the patient's rest is achieved.

[0004] However, the current pipeline protection device has the following problems: When the humidifying bottle is connected to the oxygen supply pipe and used, the oxygen supply pipe will be subjected to an external pulling force and fall off from the connection of the humidifying bottle, which will cause the oxygen supply to be interrupted, making the patient unable to obtain the required oxygen supply. Especially for critically ill patients or patients who need long-term oxygen inhalation, this will have a serious impact on the treatment and rehabilitation of the patients, and may lead to acute reactions such as hypoxemia and asphyxia. Therefore, we have proposed a medical gas pipeline protection device. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a medical gas pipeline protection device to solve the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A medical gas pipeline protection device includes a humidifying bottle main body. An outer wall of the humidifying bottle main body is fixedly connected with a connecting pipe. An oxygen supply pipe is sleeved on an outer wall of the connecting pipe. A regulating valve is arranged on the outer wall of the humidifying bottle main body. An anti-pulling device is arranged on the outer wall of the humidifying bottle main body. The anti-pulling device includes an arc-shaped plate. An inner arc surface of the arc-shaped plate is fixedly connected to the outer wall of the humidifying bottle main body. Two placing frames are fixedly connected to a top of the arc-shaped plate. A moving arc block is slidably connected to an inner wall of each of the two placing frames. An elastic telescopic arc rod is fixedly connected to the inner wall of the placing frame. A telescopic end of the elastic telescopic arc rod is fixedly connected to a side surface of the moving arc block. A connecting short column is fixedly connected to a top of the moving arc block. A contact roller is rotatably connected to a top of the connecting short column. A one-way bearing is fixedly connected to a bottom of the contact roller. A plurality of long grooves are formed in an outer wall of the contact roller. Connect the humidifying bottle main body to an external gas transmission pipe, then sleeve one end of the oxygen supply pipe onto the connecting pipe, insert the other end of the oxygen supply pipe into the patient's nostril, and then adjust the patient's oxygen inhalation speed through the regulating valve; before the staff sleeves one end of the oxygen supply pipe onto the connecting pipe, the staff pushes the two contact rollers away from the connecting pipe. The movement of the contact roller will drive the moving arc block to squeeze the elastic telescopic arc rod through the connecting short column. Then sleeve the oxygen supply pipe onto the connecting pipe. Then the staff stops pushing the two contact rollers. Therefore, the elastic telescopic arc rod will drive the moving arc block, the connecting short column and the contact roller to support the oxygen supply pipe through its own elastic force. The continuous movement of the oxygen supply pipe along the connecting pipe towards the humidifying bottle main body will drive the long grooves to rotate until the installation of the oxygen supply pipe is completed. When the oxygen supply pipe is subjected to external dragging force, at this time, the oxygen supply pipe has a tendency to drive the contact roller to rotate. Since the one-way bearing will limit the one-way rotation of the contact roller, the one-way bearing will limit the rotation of the contact roller.

[0007] According to the above technical solution, a rotating column is rotatably connected to a top of the contact roller. A bidirectional arc-shaped telescopic plate is fixedly connected to a top of the rotating column. An elastic telescopic plate is fixedly connected to a top of a fixed end of the bidirectional arc-shaped telescopic plate. A contact ring is fixedly connected to a telescopic end of the elastic telescopic plate. When the oxygen supply pipe moves on the surface of the connecting pipe, the oxygen supply pipe will push the contact ring to move. The movement of the contact ring will stretch the elastic telescopic plate. After the oxygen supply pipe is connected to the connecting pipe, the staff observes the contact between the contact ring and the oxygen supply pipe to ensure that the contact ring is in full contact with the oxygen supply pipe.

[0008] According to the above technical solution, an inner wall of the one-way bearing is in contact with an outer wall of the connecting short column. An inner wall of the contact ring is in contact with an outer wall of the connecting pipe. The contact ring is located on a displacement track of the oxygen supply pipe.

[0009] According to the above technical solution, a pollution prevention device is provided on the outer arc surface of the arc-shaped plate. The pollution prevention device includes an orbital block. A slider is slidably connected to the inner wall of the orbital groove of the orbital block. A spring is provided between the slider and the orbital block. The top of the slider is fixedly connected to an L-shaped rod. One end of the L-shaped rod away from the slider is fixedly connected to a semi-circular protection plate. The side surface of the semi-circular protection plate is in contact with the outer wall of the oxygen supply pipe. Before the oxygen supply pipe is sleeved onto the connecting pipe, the staff moves the two semi-circular protection plates in opposite directions through the two L-shaped rods. At the same time, the two L-shaped rods drive the slider to compress the spring, so that the oxygen supply pipe can be sleeved onto the connecting pipe. After the oxygen supply pipe is detached from the connecting pipe, the spring drives the slider, the L-shaped rod and the semi-circular protection plate to reset through its own elastic force.

[0010] According to the above technical solution, a sealing ring is fixedly connected to one end of the connecting pipe. The sealing ring is located on the displacement track of the semi-circular protection plate. The outer wall of the sealing ring is in contact with the inner wall of the oxygen supply pipe. The semi-circular protection plate presses the sealing ring.

[0011] According to the above technical solution, an anti-bending device is provided on the side surface of the orbital block. The anti-bending device includes an L-shaped telescopic plate. The telescopic end of the L-shaped telescopic plate is fixedly connected to the side surface of the orbital block. A cylinder ring is fixedly connected to the top of the L-shaped telescopic plate. Before the oxygen supply pipe is sleeved onto the connecting pipe, the oxygen supply pipe will pass through the cylinder ring first, and the cylinder ring will provide appropriate restraint force.

[0012] According to the above technical solution, a fixing block is fixedly connected to the top of the cylinder ring. A U-shaped rod is fixedly connected to the top of the fixing block. A support plate is fixedly connected to the side surface of the fixed end of the bidirectional arc-shaped telescopic plate. A long rod passes through and rotates on the side surface of the support plate. One end of the long rod close to the U-shaped rod is fixedly connected to an orbital column. A spiral groove is provided on the outer wall of the long rod close to the U-shaped rod. A support block is fixedly connected to the top of the contact ring. The movement of the contact ring will drive the support block to move at the same time. The movement of the support block will drive the internal moving block to move along the spiral groove, so that the long rod rotates. The rotation of the long rod will drive the orbital column to rotate. The rotation of the orbital column will cause the U-shaped rod to move back and forth along the orbital groove of the orbital column. The back-and-forth movement of the U-shaped rod drives the fixing block to move back and forth.

[0013] According to the above technical solution, a moving block in contact with the inner wall of the spiral groove is fixedly connected to the inner wall of the support block. One end of the U-shaped rod away from the fixing block is in contact with the inner wall of the orbital groove of the orbital column. The inner wall of the cylinder ring is in contact with the outer wall of the oxygen supply pipe.

[0014] The present invention provides a medical gas pipeline protection device. It has the following beneficial effects:

[0015] (1) The present invention cooperates with the placement frame, the elastic telescopic arc rod, the movable arc block, the connecting short column, the friction roller, the one-way bearing, and the long groove, so that the friction roller limits the displacement of the oxygen supply tube caused by the drag force, thereby preventing the oxygen supply tube from falling off the connecting tube due to the drag of external force, which will cause the oxygen supply to be interrupted and the patient cannot get the required oxygen supply, especially for critically ill patients or patients who need long-term oxygen inhalation. This will have a serious impact on the patient's treatment and rehabilitation, and may cause acute reactions such as hypoxia and suffocation. At the same time, the long groove will increase the friction between the oxygen supply tube and the connecting tube, thereby further preventing the problem of the oxygen supply tube falling off. At the same time, through the cooperation of the elastic telescopic plate, the friction ring, and the oxygen supply tube, after the oxygen supply tube is connected to the connecting tube, the staff observes the contact between the friction ring and the oxygen supply tube, thereby ensuring that the friction ring is in full contact with the oxygen supply tube, thereby avoiding the problem that the oxygen supply tube is in a tilted state when it is sleeved on the connecting tube, which easily causes the oxygen supply tube to fall off the connecting tube.

[0016] (2) The present invention cooperates with the track block, the slider, the spring, the L-shaped rod, and the semicircular protective plate so that the spring can drive the slider, the L-shaped rod, and the semicircular protective plate to reset through its own elastic force. The reset of the semicircular protective plate will block the pipe mouth of the connecting pipe, thereby preventing dust, impurities or other external substances from entering the humidification bottle body through the connecting pipe, keeping the environment inside the humidification bottle body clean, and preventing pollutants from affecting the gas transmission quality; at the same time, through the cooperation of the semicircular protective plate and the sealing ring, the semicircular protective plate will squeeze the sealing ring, thereby further sealing the pipe mouth of the connecting pipe.

[0017] (3) The present invention enables the oxygen supply tube to pass through the cylinder ring first through the coordination of the cylinder ring and the oxygen supply tube, and the cylinder ring provides appropriate restraining force to ensure that the oxygen supply tube will not be twisted or folded during the connection process, thereby ensuring the service life of the oxygen supply tube; at the same time, through the coordination of the cylinder ring, the fixed block, the U-shaped rod, the support plate, the long rod, the track column, the spiral groove, and the support block, the rotation of the track column causes the U-shaped rod to move back and forth along the track groove of the track column, the back and forth movement of the U-shaped rod drives the fixed block to move back and forth, and the back and forth movement of the fixed block drives the cylinder ring to move back and forth on the surface of the oxygen supply tube, thereby further ensuring that the oxygen supply tube will not be twisted or folded during the connection process.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] Please refer to Figures 1-7, an embodiment of the present invention is: a medical gas pipeline protection device, including a humidifying bottle main body 1, a connecting pipe 2 is fixedly connected to the outer wall of the humidifying bottle main body 1, an oxygen supply pipe 3 is sleeved on the outer wall of the connecting pipe 2, a regulating valve 4 is arranged on the outer wall of the humidifying bottle main body 1, and an anti-pulling device 5 is arranged on the outer wall of the humidifying bottle main body 1. The anti-pulling device 5 includes an arc-shaped plate 51, the inner arc surface of the arc-shaped plate 51 is fixedly connected to the outer wall of the humidifying bottle main body 1, two placement frames 52 are fixedly connected to the top of the arc-shaped plate 51, a moving arc block 54 is slidably connected to the inner wall of each of the two placement frames 52, an elastic telescopic arc rod 53 is fixedly connected to the inner wall of the placement frame 52, and the telescopic end of the elastic telescopic arc rod 53 is fixedly connected to the side surface of the moving arc block 54. A connecting short column 55 is fixedly connected to the top of the moving arc block 54, a resisting roller 56 is rotatably connected to the top of the connecting short column 55, a one-way bearing 57 is fixedly connected to the bottom of the resisting roller 56, and a plurality of long grooves 58 are formed in the outer wall of the resisting roller 56. Through the setting of the above structure, the one-way bearing 57 will limit the rotation of the resisting roller 56, so that the resisting roller 56 restricts the displacement that the oxygen supply pipe 3 will undergo due to the dragging force, thereby avoiding the oxygen supply pipe 3 falling off from the connecting pipe 2 due to external dragging force, which will cause the oxygen supply to be interrupted and the patient cannot obtain the required oxygen supply. Especially for critically ill patients or patients who need long-term oxygen inhalation, this will have a serious impact on the treatment and rehabilitation of the patient, and may cause acute reactions such as hypoxemia and asphyxia. At the same time, the long grooves 58 will increase the friction force with the oxygen supply pipe 3, thereby further preventing the problem of the oxygen supply pipe 3 falling off.

[0028] A rotating column 59 is rotatably connected to the top of the resisting roller 56, a bidirectional arc-shaped telescopic plate 510 is fixedly connected to the top of the rotating column 59, an elastic telescopic plate 511 is fixedly connected to the top of the fixed end of the bidirectional arc-shaped telescopic plate 510, a resisting ring 512 is fixedly connected to the telescopic end of the elastic telescopic plate 511, the inner wall of the resisting ring 512 is in contact with the outer wall of the connecting pipe 2, and the resisting ring 512 is located on the displacement track of the oxygen supply pipe 3. Through the setting of the above structure, after the oxygen supply pipe 3 is connected to the connecting pipe 2, the staff observes the contact between the resisting ring 512 and the oxygen supply pipe 3, so as to ensure that the resisting ring 512 is in full contact with the oxygen supply pipe 3, avoiding the problem that the oxygen supply pipe 3 is in an inclined state when sleeved on the connecting pipe 2 and is likely to fall off from the connecting pipe 2.

[0029] The outer arc surface of the arc-shaped plate 51 is provided with a pollution prevention device 6. The pollution prevention device 6 includes an orbital block 61. A slider 62 is slidably connected to the inner wall of the orbital groove of the orbital block 61. A spring 63 is arranged between the slider 62 and the orbital block 61. The top of the slider 62 is fixedly connected with an L-shaped rod 64. One end of the L-shaped rod 64 far from the slider 62 is fixedly connected with a semi-circular protection plate 65. The side surface of the semi-circular protection plate 65 is in contact with the outer wall of the oxygen supply pipe 3. Through the setting of the above structure, the reset of the semi-circular protection plate 65 will block the pipe orifice of the connecting pipe 2, thereby preventing dust, impurities or other external substances from entering the humidifying bottle main body 1 through the connecting pipe 2, keeping the environment inside the humidifying bottle main body 1 clean, and preventing pollutants from affecting the gas transmission quality.

[0030] One end of the connecting pipe 2 is fixedly connected with a sealing ring 66. The sealing ring 66 is located on the displacement track of the semi-circular protection plate 65. The outer wall of the sealing ring 66 is in contact with the inner wall of the oxygen supply pipe 3. Through the setting of the above structure, the semi-circular protection plate 65 will squeeze the sealing ring 66, thereby further sealing the pipe orifice of the connecting pipe 2.

[0031] When in use, the humidifier bottle body 1 is connected to the external air supply pipe, and then one end of the oxygen supply pipe 3 is sleeved on the connecting pipe 2, and the other end of the oxygen supply pipe 3 is inserted into the patient's nostril, and then the patient's oxygen inhalation speed is adjusted by the regulating valve 4; when the staff sleeves one end of the oxygen supply pipe 3 on the connecting pipe 2, the staff pushes the two friction rollers 56 away from the connecting pipe 2, and the movement of the friction rollers 56 drives the moving arc block 54 to squeeze the elastic telescopic arc rod 53 through the connecting short column 55, and then the oxygen supply pipe 3 is sleeved When the oxygen supply tube 3 is connected to the connecting tube 2, the staff no longer pushes the two friction rollers 56, so the elastic telescopic arc rod 53 will drive the movable arc block 54, the connecting short column 55 and the friction roller 56 to support the oxygen supply tube 3 through its own elastic force. The oxygen supply tube 3 continues to move along the connecting tube 2 toward the humidification bottle body 1, which will drive the long groove 58 to rotate until the oxygen supply tube 3 is installed. When the oxygen supply tube 3 is dragged by external force, the oxygen supply tube 3 has a tendency to drive the friction roller 56 to rotate. Since the one-way bearing 57 will limit the friction roller 56 from rotating The one-way bearing 57 can limit the rotation of the friction roller 56, so that the friction roller 56 can limit the displacement of the oxygen supply tube 3 caused by the drag force, thereby preventing the oxygen supply tube 3 from being dragged by external force and falling off from the connecting tube 2, which will cause the oxygen supply to be interrupted and the patient cannot get the required oxygen supply, especially for critically ill patients or patients who need long-term oxygen inhalation, which will have a serious impact on the patient's treatment and rehabilitation, and may cause acute reactions such as hypoxia and suffocation. At the same time, the long groove 58 will increase the friction between the oxygen supply tube 3 and the oxygen supply tube 3. When the oxygen supply tube 3 moves on the surface of the connecting tube 2, the oxygen supply tube 3 will push the abutment ring 512 to move, and the movement of the abutment ring 512 will stretch the elastic expansion plate 511. After the oxygen supply tube 3 is connected to the connecting tube 2, the staff observes the contact between the abutment ring 512 and the oxygen supply tube 3 to ensure that the abutment ring 512 is in full contact with the oxygen supply tube 3, thereby avoiding the problem that the oxygen supply tube 3 is in a tilted state when it is sleeved on the connecting tube 2, which may easily cause the oxygen supply tube 3 to fall off from the connecting tube 2.

[0032] Before slipping the oxygen supply tube 3 onto the connecting tube 2, the staff move two semi-circular protection plates 65 in opposite directions through two L-shaped rods 64. At the same time, the two L-shaped rods 64 drive the sliders 62 to squeeze the springs 63, enabling the oxygen supply tube 3 to be slipped onto the connecting tube 2. After the oxygen supply tube 3 is detached from the connecting tube 2, the springs 63 drive the sliders 62, L-shaped rods 64, and semi-circular protection plates 65 to reset through their own elastic forces. The reset of the semi-circular protection plates 65 shields the nozzle of the connecting tube 2, preventing dust, impurities, or other external substances from entering the humidifying bottle body 1 through the connecting tube 2, maintaining the cleanliness of the environment inside the humidifying bottle body 1, and preventing pollutants from affecting the gas transmission quality. At the same time, the semi-circular protection plates 65 squeeze the sealing rings 66 to further seal the nozzle of the connecting tube 2.

[0033] Please refer to Figures 1-7 , based on the above embodiments, in another embodiment of the present invention, an anti-bending device 7 is provided on the side of the track block 61. The anti-bending device 7 includes an L-shaped telescopic plate 71. The telescopic end of the L-shaped telescopic plate 71 is fixedly connected to the side of the track block 61, and a cylinder ring 72 is fixedly connected to the top of the L-shaped telescopic plate 71. Through the setting of the above structure, the oxygen supply tube 3 will first pass through the cylinder ring 72, and the cylinder ring 72 will provide appropriate restraint force to ensure that the oxygen supply tube 3 will not be distorted or folded during the connection process, thereby ensuring the service life of the oxygen supply tube 3.

[0034] A fixing block 73 is fixedly connected to the top of the cylinder ring 72, and a U-shaped rod 74 is fixedly connected to the top of the fixing block 73. A support plate 75 is fixedly connected to the side of the fixed end of the bidirectional arc-shaped telescopic plate 510. A long rod 76 penetrates and rotates through the side of the support plate 75. One end of the long rod 76 close to the U-shaped rod 74 is fixedly connected to an orbital column 77. A spiral groove 78 is formed on the outer wall of the long rod 76 close to the U-shaped rod 74. A support block 79 is fixedly connected to the top of the contact ring 512, and a moving block in contact with the inner wall of the spiral groove 78 is fixedly connected to the inner wall of the support block 79. One end of the U-shaped rod 74 away from the fixing block 73 is in contact with the inner wall of the track groove of the orbital column 77, and the inner wall of the cylinder ring 72 is in contact with the outer wall of the oxygen supply tube 3. Through the setting of the above structure, the back-and-forth movement of the U-shaped rod 74 drives the fixing block 73 to move back and forth, and the back-and-forth movement of the fixing block 73 drives the cylinder ring 72 to move back and forth on the surface of the oxygen supply tube 3, further ensuring that the oxygen supply tube 3 will not be distorted or folded during the connection process.

[0035] In use, before the oxygen supply pipe 3 is sleeved onto the connecting pipe 2, the oxygen supply pipe 3 will first pass through the cylinder ring 72, and the cylinder ring 72 will provide appropriate restraint force to ensure that the oxygen supply pipe 3 will not be distorted or folded during the connection process, thus ensuring the service life of the oxygen supply pipe 3; the movement of the abutting ring 512 will simultaneously drive the support block 79 to move, and the movement of the support block 79 will drive the internal moving block to move along the spiral groove 78, so that the long rod 76 rotates. The rotation of the long rod 76 will drive the track column 77 to rotate, and the rotation of the track column 77 will cause the U-shaped rod 74 to move back and forth along the track groove of the track column 77. The back-and-forth movement of the U-shaped rod 74 drives the fixed block 73 to move back and forth, and the back-and-forth movement of the fixed block 73 drives the cylinder ring 72 to move back and forth on the surface of the oxygen supply pipe 3, thereby further ensuring that the oxygen supply pipe 3 will not be distorted or folded during the connection process.

[0036] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
