Description

Technical Field

[0001] The present invention relates to the technical field of oxygen inhalation devices, in particular to a medical gas pipeline protection device. Background Art

[0002] Oxygen inhalation is a commonly used clinical treatment, primarily used to alleviate hypoxia, correct arterial hypoxia, and promote metabolism. Appropriate oxygen inhalation helps increase oxygen partial pressure and saturation, and assists in the treatment of a variety of conditions, such as respiratory failure, chronic bronchitis, cerebrovascular disease, and coronary heart disease. Even if 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 and shock, and for fetal monitoring.

[0003] A Chinese patent with patent publication number CN219921788U discloses a medical oxygen humidification 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 to a tank body, the inner side of the protective shell is provided with a slide groove, the outer surface of the tank body is fixedly connected to a slider, the surface of the slide groove is slidably connected to the slider, the upper surface of the protective shell is provided with a second fixed port, the surface of the second fixed port is provided with an oxygen outlet pipe, the lower surface of the oxygen outlet pipe is provided with a second plastic telescopic tube, the other end of the second plastic telescopic tube is provided in the tank body, and an oxygen inhalation mask is provided at the end of the oxygen outlet pipe away from the second fixed port, the inner wall of the outer surface of the protective shell is provided with a cavity, and the surface of the cavity is filled with sound insulation cotton. The patent achieves the purpose of improving the practicality of the device through the arrangement of a first spring, a micro switch, a top block and a signal transmission module, and achieves the purpose of improving the patient's rest comfort through the arrangement of sound insulation cotton.

[0004] However, the current pipeline protection device has the following problems: when the humidifier bottle is connected to the oxygen supply tube and used, the oxygen supply tube will be pulled out of the humidifier bottle connection due to external tension, resulting in an interruption of oxygen supply and the patient cannot get the required oxygen supply. This is especially true for critically ill patients or patients who need long-term oxygen inhalation. This will have a serious impact on the patient's treatment and recovery, and may lead to acute reactions such as hypoxia and suffocation. Therefore, we have proposed a medical gas pipeline protection device. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a medical gas pipeline protection device, which solves the problems raised in the above background technology.

[0006] To achieve the above object, the present invention is implemented through the following technical scheme: a medical gas pipeline protection device, comprising a humidifier bottle main body, the outer wall of the humidifier bottle main body is fixedly connected to a connecting pipe, the outer wall of the connecting pipe is sleeved with an oxygen supply pipe, the outer wall of the humidifier bottle main body is provided with a regulating valve, the outer wall of the humidifier bottle main body is provided with an anti-pull device, the anti-pull device comprises an arc plate, the inner arc surface of the arc plate is fixedly connected to the outer wall of the humidifier bottle main body, the top of the arc plate is fixedly connected to two placement frames, the inner walls of the two placement frames are slidably connected to movable arc blocks, the inner wall of the placement frame is fixedly connected to an elastic telescopic arc rod, the telescopic end of the elastic telescopic arc rod is fixedly connected to the side of the movable arc block, the top of the movable arc block is fixedly connected to a connecting short column, the top of the connecting short column is rotatably connected to a friction roller, the bottom of the friction roller is fixedly connected to a one-way bearing, and the outer wall of the friction roller is provided with a plurality of long grooves, When the staff puts one end of the oxygen supply tube on the connecting tube, the staff pushes the two friction rollers in the direction away from the connecting tube, and the movement of the friction rollers drives the movable arc block to squeeze the elastic telescopic arc rod through the connecting short column, and then the oxygen supply tube is put on the connecting tube. Then the staff no longer pushes the two friction rollers, so the elastic telescopic arc rod drives the movable arc block, the connecting short column and the friction roller to support the oxygen supply tube through its own elastic force, and the oxygen supply tube continues to move along the connecting tube toward the humidification bottle main body, driving the long slot to rotate until the oxygen supply tube is installed. When the oxygen supply tube is dragged by external force, the oxygen supply tube tends to drive the friction roller to rotate. Since the one-way bearing limits the one-way rotation of the friction roller, the one-way bearing limits the rotation of the friction roller.

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

[0008] According to the above technical solution, the inner wall of the one-way bearing contacts the outer wall of the connecting short column, the inner wall of the interference ring contacts the outer wall of the connecting pipe, and the interference ring is located on the displacement track of the oxygen supply pipe.

[0009] The L-shaped rod is fixedly connected to the top of the slider, and the end of the L-shaped rod away from the slider is fixedly connected to the semicircular protective plate. The side surface of the semicircular protective plate contacts the outer wall of the oxygen supply tube. Before the oxygen supply tube is put on the connecting tube, the staff moves the two semicircular protective plates in opposite directions through the two L-shaped rods. At the same time, the two L-shaped rods will drive the slider to squeeze the spring, so that the oxygen supply tube can be put on the connecting tube. When the oxygen supply tube is removed from the connecting tube, the spring will drive the slider, the L-shaped rod and the semicircular protective plate to reset through its own elastic force.

[0010] According to the above technical solution, one end of the connecting pipe is fixedly connected to a sealing ring, which is located on the displacement track of the semicircular protective plate. The outer wall of the sealing ring contacts the inner wall of the oxygen supply pipe, and the semicircular protective plate will squeeze the sealing ring.

[0011] According to the above technical solution, an anti-bending device is provided on the side of the track block, and 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 of the track block, and the top of the L-shaped telescopic plate is fixedly connected to a tube ring. Before the oxygen supply tube is put into the connecting tube, the oxygen supply tube will pass through the tube ring first, and the tube ring will provide appropriate restraint force.

[0012] The top of the cylinder ring is fixedly connected to a fixed block, the top of the fixed block is fixedly connected to a U-shaped rod, the fixed end side of the bidirectional arc-shaped telescopic plate is fixedly connected to a support plate, the side of the support plate is penetrated and rotated by a long rod, the end of the long rod close to the U-shaped rod is fixedly connected to the track column, and the long rod is provided with a spiral groove near the outer wall of the U-shaped rod, and the top of the interference ring is fixedly connected to the support block, and the movement of the interference ring will also drive the support block to move, and the movement of the support block will drive the internal moving block to move along the spiral groove, thereby causing the long rod to rotate, and the rotation of the long rod will drive the track column to rotate, and the rotation of the track column will cause the U-shaped rod to move back and forth along the track groove of the track column, and the back-and-forth movement of the U-shaped rod drives the fixed block to move back and forth.

[0013] According to the above technical solution, the inner wall of the support block is fixedly connected with a movable block in contact with the inner wall of the spiral groove, the end of the U-shaped rod away from the fixed block is in contact with the inner wall of the track groove of the track column, and the inner wall of the tube ring is in contact with the outer wall of the oxygen supply pipe.

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

[0015] (1) The present invention uses the coordination of 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 to limit 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 the 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 coordination 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 cooperates with the cylinder ring and the oxygen supply tube so that the oxygen supply tube will pass through the cylinder ring first. The cylinder ring will provide 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 cooperation 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 will cause 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] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] See also Figure 1-Figure 7, one embodiment of the present invention is: a medical gas pipeline protection device, including a humidifier bottle main body 1, the outer wall of the humidifier bottle main body 1 is fixedly connected with a connecting pipe 2, the outer wall of the connecting pipe 2 is sleeved with an oxygen supply pipe 3, the outer wall of the humidifier bottle main body 1 is provided with a regulating valve 4, the outer wall of the humidifier bottle main body 1 is provided with an anti-pull device 5, the anti-pull device 5 includes an arc plate 51, the inner arc surface of the arc plate 51 is fixedly connected to the outer wall of the humidifier bottle main body 1, the top of the arc plate 51 is fixedly connected to two placement frames 52, the inner walls of the two placement frames 52 are slidably connected with a moving arc block 54, the inner wall of the placement frame 52 is fixedly connected with an elastic telescopic arc rod 53, the telescopic end of the elastic telescopic arc rod 53 is fixedly connected to the side of the moving arc block 54, the top of the moving arc block 54 is fixedly connected with a connecting short column 55, The top of the connecting column 55 is rotatably connected to a resistance roller 56, and the bottom of the resistance roller 56 is fixedly connected to a one-way bearing 57. The outer wall of the resistance roller 56 is provided with a plurality of long grooves 58. Through the arrangement of the above structure, the one-way bearing 57 will limit the rotation of the resistance roller 56, so that the resistance roller 56 can limit the displacement of the oxygen supply tube 3 caused by the dragging force, thereby avoiding the oxygen supply tube 3 from being dragged off from the connecting tube 2 by 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 recovery, 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, thereby further preventing the problem of the oxygen supply tube 3 falling off.

[0028] The top of the interference roller 56 is rotatably connected to a rotating column 59, and the top of the rotating column 59 is fixedly connected to a bidirectional arc-shaped telescopic plate 510, and the top of the fixed end of the bidirectional arc-shaped telescopic plate 510 is fixedly connected to an elastic telescopic plate 511, and the telescopic end of the elastic telescopic plate 511 is fixedly connected to a interference ring 512, and the inner wall of the interference ring 512 contacts the outer wall of the connecting pipe 2, and the interference ring 512 is located on the displacement trajectory of the oxygen supply pipe 3. Through the arrangement of the above structure, after the oxygen supply pipe 3 is connected to the connecting pipe 2, the staff observes the contact between the interference ring 512 and the oxygen supply pipe 3, thereby ensuring that the interference ring 512 is in full contact with the oxygen supply pipe 3, avoiding the problem that the oxygen supply pipe 3 is in a tilted state when it is sleeved on the connecting pipe 2, which easily causes the oxygen supply pipe 3 to fall off from the connecting pipe 2.

[0029] The outer arc surface of the arc plate 51 is provided with an anti-pollution device 6, which includes a track block 61. The inner wall of the track groove of the track block 61 is slidably connected to a slider 62. A spring 63 is provided between the slider 62 and the track block 61. The top of the slider 62 is fixedly connected to an L-shaped rod 64. The end of the L-shaped rod 64 away from the slider 62 is fixedly connected to a semicircular protective plate 65. The side of the semicircular protective plate 65 contacts the outer wall of the oxygen supply tube 3. Through the setting of the above structure, the resetting of the semicircular protective plate 65 will block the pipe mouth of the connecting tube 2, thereby preventing dust, impurities or other external substances from entering the humidification bottle main body 1 through the connecting tube 2, keeping the environment inside the humidification bottle main body 1 clean, and preventing pollutants from affecting the gas transmission quality.

[0030] A sealing ring 66 is fixedly connected to one end of the connecting pipe 2. The sealing ring 66 is located on the displacement track of the semicircular protective plate 65. The outer wall of the sealing ring 66 contacts the inner wall of the oxygen supply pipe 3. Through the setting of the above structure, the semicircular protective plate 65 will squeeze the sealing ring 66, thereby further sealing the pipe mouth 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 moving 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 an 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 off from the connecting tube 2 by the 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 recovery, 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 is connected to the connecting tube 2, the staff observes the contact between the friction ring 512 and the oxygen supply tube 3 to ensure that the friction 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 the oxygen supply tube 3 is put on the connecting tube 2, the staff moves the two semicircular protective plates 65 in opposite directions through the two L-shaped rods 64. At the same time, the two L-shaped rods 64 will drive the slider 62 to squeeze the spring 63, so that the oxygen supply tube 3 can be put on the connecting tube 2. When the oxygen supply tube 3 is removed from the connecting tube 2, the spring 63 will drive the slider 62, the L-shaped rod 64 and the semicircular protective plate 65 to reset through its own elastic force. The reset of the semicircular protective plate 65 will block the pipe mouth of the connecting tube 2, thereby preventing dust, impurities or other external substances from entering the humidification bottle main body 1 through the connecting tube 2, keeping the environment inside the humidification bottle main body 1 clean, and preventing pollutants from affecting the gas transmission quality; at the same time, the semicircular protective plate 65 will squeeze the sealing ring 66, thereby further sealing the pipe mouth of the connecting tube 2.

[0033] See also Figure 1-Figure 7 On the basis of the above embodiment, 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. The top of the L-shaped telescopic plate 71 is fixedly connected to a tube ring 72. Through the setting of the above structure, the oxygen supply tube 3 will pass through the tube ring 72 first. The tube ring 72 will provide appropriate restraint force to ensure that the oxygen supply tube 3 will not be twisted or folded during the connection process, thereby ensuring the service life of the oxygen supply tube 3.

[0034] The top of the cylinder ring 72 is fixedly connected with a fixed block 73, the top of the fixed block 73 is fixedly connected with a U-shaped rod 74, the fixed end side of the bidirectional arc telescopic plate 510 is fixedly connected with a support plate 75, the side of the support plate 75 is penetrated and rotated with a long rod 76, the end of the long rod 76 close to the U-shaped rod 74 is fixedly connected to a track column 77, the outer wall of the long rod 76 close to the U-shaped rod 74 is provided with a spiral groove 78, the top of the interference ring 512 is fixedly connected with a support block 79, the inner wall of the support block 79 A moving block is fixedly connected to the inner wall of the spiral groove 78, and the end of the U-shaped rod 74 away from the fixed block 73 is in contact with the inner wall of the track groove of the track column 77. The inner wall of the tube ring 72 is in contact with the outer wall of the oxygen supply pipe 3. Through the arrangement of the above structure, 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 tube 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 twisted or folded during the connection process.

[0035] During use, before the oxygen supply tube 3 is put onto the connecting tube 2, the oxygen supply tube 3 will first pass through the tube ring 72, and the tube ring 72 will provide appropriate restraining force to ensure that the oxygen supply tube 3 will not be twisted or folded during the connection process, thereby ensuring the service life of the oxygen supply tube 3; the movement of the interference ring 512 will also 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, thereby causing the long rod 76 to rotate, and 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, and 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 tube ring 72 to move back and forth on the surface of the oxygen supply tube 3, thereby further ensuring that the oxygen supply tube 3 will not be twisted or folded during the connection process.

[0036] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
