Description

Technical Field

[0001] The present invention relates to the technical field of respiratory assistance, in particular to an auxiliary device for dyspnea in clinical anesthesia department. Background Art

[0002] Clinical anesthesia refers to the reversible inhibition of the patient's central nervous system or local nerves by professional anesthesiologists through drugs or other techniques during surgery or invasive procedures. It can prevent patients from suffering pain during surgery, reduce surgical stress reactions, and help patients go through the perioperative period more smoothly.

[0003] With the development of modern medicine, anesthesia has been widely used in clinical medicine as an effective means to isolate patients from pain. During the anesthesia process, since anesthetic drugs themselves will inhibit the patient's respiratory function, interfere with the normal regulation of the respiratory center, causing changes in respiratory frequency and depth, and even respiratory arrest, a clinical anesthesia department is needed to provide an auxiliary device for respiratory distress to ensure the patient's normal breathing.

[0004] At present, the auxiliary devices for breathing difficulties on the market are mainly composed of an air source, an inhalation tube, a breathing mask and an exhalation tube. When in use, the air source is used to provide oxygen, and the oxygen is transported to the exhalation mask through the inhalation tube, and the patient exhales through the exhalation tube. However, the edges of traditional masks are mostly made of hard silicone material, which can easily cause pressure damage to the bridge of the nose and cheekbones when worn for a long time. To solve the above problems, the existing technology uses an airbag composite edge design to enable the mask to fit tightly to the patient's face, ensuring sealing and reducing the sense of oppression. However, when patients are undergoing deep anesthesia, oral intubation is often required, and the patient will bite the tube during the intubation process, resulting in reduced gas circulation. The existing technology can prevent the patient from biting the tube by adding a gasket, but the patient cannot swallow during intubation, and the saliva in the mouth will flow into the airway along the tube wall, resulting in a sudden increase in ventilation resistance and causing suffocation, reducing the safety of the device and failing to meet the needs of users.

One end of the spring 483 is fixedly connected to the inner side of the inner cavity 45. The spring 483 can push the pawl 47 to engage with the ratchet 46.

[0037] Specifically, when using the device, first buckle the shell 1 on the patient's face, and then press the first guard plate 42 and the second guard plate 44 on both sides of the device to make it fit tightly with the patient's face, so as to more conveniently fix the device on the patient's face, and in the process of using the device, the spring 483 can push the pawl 47 to engage with the ratchet 46, thereby preventing the rotating rod 43 from rotating, ensuring that the device can be firmly fixed on the patient's face and avoiding loosening during use. When the device needs to be disassembled, the lever 481 is moved, and the lever 481 will drive the pawl 47 to rotate. The rotation of the pawl 47 will disengage from the meshing state with the ratchet 46, and the first guard plate 42 and the second guard plate 44 can be easily rotated to remove the device from the patient's face, so that medical staff can use the device more conveniently and quickly, thereby improving the convenience of using the device.

[0038] Reference Figure 4 and Figure 6 The suction mechanism 2 further includes a slide rail 29, two slide rails 29 are respectively fixedly connected to the upper and lower sides of the inner front end of the hollow block 21, and the inner side of the slide rail 29 is slidably connected to the frame 22.

[0039] Specifically, the slide rail 29 can provide support and guidance for the frame 22 , and the U-shaped plate 38 can provide guidance for the clamping block 36 , so that the clamping block 36 can accurately fix the oxygen tube 310 .

[0040] Reference Figure 1 and Figure 2 The protection mechanism 3 further includes a one-way valve 39, which is arranged on the right side of the front wall of the shell 1. One side of the multiple blocks 36 is provided with a common oxygen tube 310. The front end of the oxygen tube 310 sequentially passes through the sealing layer 5 and the shell 1.

[0041] Specifically, the gas exhaled by the patient can be discharged from the interior of the device through the one-way valve 39, and oxygen is provided to the patient through the oxygen tube 310.

[0042] Working principle: When using the device, the motor 273 drives the half gear 272 to rotate. Since the first racks 271 on both sides of the frame 22 are meshed with the half gears 272, when the half gears 272 rotate, the first rack 271 drives the left and right sides of the frame 22 to reciprocate, and the second rack 23 moves accordingly. Since the flat gear 25 is meshed with the second rack 23, when the second rack 23 moves, the flat gear 25 drives the transmission rod 24 to rotate back and forth, thereby driving the absorption head 26 to rotate left and right, thereby absorbing all the saliva around the patient's mouth, so that the saliva will not enter the airway, and by connecting to the external negative pressure equipment through the suction tube 282, negative pressure can be provided to the absorption head 26 through the connecting tube 281;

[0043] When using the device, the oxygen tube 310 is first inserted into the patient's trachea, and then the bite tube 31 is placed in the patient's mouth. The movable ring 373 is pushed forward, and the second toothed ring 374 is disengaged from the meshing state with the first toothed ring 372. At this time, the movable ring 373 is rotated, and the movable ring 373 drives the rotating ring 33 to rotate through the connecting column 375. When the rotating ring 33 rotates, it can push the plug-in column 35 to move through the curved groove 34. The movement of the plug-in column 35 can drive the clamping block 36 to move. The movement of the surrounding clamping blocks 36 can fix the oxygen tube 310, so that the oxygen tube 310 will not be disengaged or displaced during use.

[0044] Finally, when using the device, first place the shell 1 on the patient's face, and then press the first guard plate 42 and the second guard plate 44 on both sides so that the first guard plate 42 and the second guard plate 44 fit tightly against the patient's face, thereby more conveniently fixing the device, and when in use, the spring 483 pushes the pawl 47 to engage with the ratchet 46, so that the rotating rod 43 does not rotate, thereby ensuring that the device is firmly fixed and will not loosen, and when it needs to be disassembled, move the lever 481, and the lever 481 will drive the pawl 47 to rotate, so that the pawl 47 disengages from the ratchet 46, so that the first guard plate 42 and the second guard plate 44 can be easily rotated, thereby disassembling the device, allowing medical staff to use the device more conveniently and quickly.
