Description

Technical Field

[0001] The present invention relates to the technical field of anesthesiology medical equipment, and in particular to an anesthesiology endotracheal tube fixing device and a use method thereof. Background Art

[0002] Anesthesiology is a branch of medicine that focuses on administering anesthesia during surgery or other medical procedures. The endotracheal tube, also known as an endotracheal tube or tracheal cannula, is a hollow, soft tube usually made of plastic (such as polyvinyl chloride). It has a certain degree of elasticity and toughness, and its shape is designed to be inserted into the human trachea. During general anesthesia, the patient's loss of consciousness, muscle relaxation, and tongue droop can easily lead to airway obstruction. After the endotracheal tube is inserted into the trachea, this situation can be effectively avoided, ensuring that air can flow in and out of the lungs smoothly.

[0003] In the prior art, the tracheal tube used in the anesthesiology department needs to be fixed when in use to prevent it from shifting or falling off. When fixing the tracheal tube used in the anesthesiology department, the adhesive tape fixing method is usually adopted. First, one end of the adhesive tape is torn off to form a Y shape, and the untorn side is pasted on one side of the patient's face, and then one of the torn adhesive tapes is pasted around the philtrum of the patient's face, and the other torn adhesive tape is pasted on the catheter and the articulator, and the catheter and the articulator are fixed, and the opposite side is fixed in the same way. When the patient has recovered spontaneous breathing and reached the indication for removing the tracheal tube, but the articulator needs to be retained to prevent the patient from biting the tongue, it is necessary to separate the catheter and the articulator and remove the tracheal tube. However, the tracheal tube and the articulator are fixed together by wrapping a double layer of adhesive tape. When separating the catheter and the articulator, it is necessary to tear off the double-layer wrapped and pasted tape, which increases the difficulty of separation and delays the treatment time for the patient, which is inconvenient.

[0004] Therefore, we propose an endotracheal tube fixing device for anesthesiology and a method of using the same, so as to solve the problems raised in the above background technology. Summary of the invention

The inner wall of the groove 420 is fixedly connected, the top ends of the two adjustment shafts 422 are respectively movably inserted through the two embedded grooves 427 to the top of the connection cover 401 and the fixed block 402, one end of the multiple elastic clamping rods 423 is respectively movably embedded in the multiple clamping sleeves 424, one end of the four sets of rotating rods 425 is respectively movably embedded in the four rotating grooves 426, the outer surface of the first tightening rope 409 is in contact with the outer surfaces of two of the limiting rods 429 and two of the limiting plates 430, the outer surface of the second tightening rope 414 is in contact with the outer surfaces of the other two limiting rods 429 and the other two limiting plates 430, and the outer surface of the first tightening rope 409 is movably embedded in the connection hole 428.

[0042] In this embodiment, when in use, the first tightening rope 409 is located at the upper position, and the second tightening rope 414 is located at the lower position. Figure 5 The movable gear 421 is located in the middle of the tightening gear 419. Fig.10 As shown in the left figure. Under the action of the limit rod 429 and the limit plate 430, the first tightening rope 409 and the second tightening rope 414 are limited respectively. At the same time, the two adjustment shafts 422 are pulled upward to drive the multiple elastic clamping rods 423 to move upward together, so that the elastic clamping ball at one end of the elastic clamping rod 423 is pulled out from the clamping sleeve 424. When the sound of the elastic clamping ball being pulled out is heard, stop pulling the adjustment shaft 422. At this time, the two movable gears 421 are driven by the adjustment shaft 422 to move upward together, from the middle position inside the tightening gear 419 to the upper position, as shown in FIG. Fig.10The middle figure shows. Then, the two adjustment shafts 422 are rotated to drive the multiple elastic clamping rods 423 to rotate above the clamping sleeve 424, and drive the two movable gears 421 to rotate together, and further drive the two tightening gears 419 to rotate, and respectively wind and tighten the first tightening rope 409 and the second tightening rope 414. As the first tightening rope 409 and the second tightening rope 414 are tightened, the square moving plate 405 and the arc moving plate 410 will be driven to move relative to each other, and the reset plate 415 will be driven to move, so that the reset spring 416 is squeezed and contracted together, and at the same time, the square fixing clamp 407 and the arc fixing clamp 412 are driven to move relative to each other through the first connecting rod 406 and the second connecting rod 411, so that the square rubber pad 408 contacts the outer surface of the articulator body 2, and the arc rubber pad 413 In contact with the outer surface of the catheter body 1, as the first tightening rope 409 and the second tightening rope 414 are further tightened, the square fixing clamp 407 and the arc-shaped fixing clamp 412 respectively clamp the articulator body 2 and the catheter body 1 together, and finally press the two adjustment shafts 422 downward, push the elastic clamping rod 423 to be clamped into the clamping sleeve 424 again, and the movable gear 421 moves to the middle of the tightening gear 419 again. Through the cooperation of the elastic clamping rod 423 and the clamping sleeve 424, the adjusting shaft 422 and the movable gear 421 are limited, thereby limiting the two tightening gears 419 after tightening to prevent self-rotation and affect the tightening state of the first tightening rope 409 and the second tightening rope 414, thereby completing the fixation between the catheter body 1 and the articulator body 2. When the catheter body 1 needs to be removed, the two adjustment shafts 422 are pulled upward again to pull the elastic clamping rod 423 out of the clamping sleeve 424, and the adjustment shaft 422 is pulled upward continuously to make the elastic clamping rod 423 enter the inner groove 427 and contact the top surface of the inner groove 427. When the adjustment shaft 422 can no longer be pulled, the movable gear 421 is completely removed from the tightening gear 419. Fig.10The middle right figure shows that at this time, the tightening gear 419 loses its limit, the square moving plate 405 and the arc moving plate 410 lose their tension, and the reset spring 416 starts to rebound, pushing the reset plate 415 to move in the opposite direction to reset, and at the same time driving the square moving plate 405 and the arc moving plate 410 to move in the opposite direction to reset, further pulling the first tightening rope 409 and the second tightening rope 414 to move, thereby driving the two tightening gears 419 to rotate and release the first tightening rope 409 and the second tightening rope 414. While the square moving plate 405 and the arc moving plate 410 move, the square fixing clamp 407 and the arc fixing clamp 412 are driven to move in the opposite direction through the first connecting rod 406 and the second connecting rod 411, loosening the clamping fixation of the catheter body 1 and the articulator body 2, and the medical staff can pull the catheter body 1 out of the patient's mouth and pass it through the fixing hole 404. Under the action of the connecting and fixing component 4, the clamping and fixing of the catheter body 1 can be automatically loosened by pulling the adjusting shaft 422, so that the medical staff can take out the catheter body 1 conveniently. The operation is simple and convenient, which saves time and can treat the patient faster. It solves the problem that when the endotracheal tube used in the anesthesia department is in use, the tube and the articulator are fixed by tape. When the patient has recovered spontaneous breathing and the endotracheal tube needs to be taken out and the articulator needs to be retained, the double-layer wrapped tape needs to be torn off, which makes separation difficult, delays the treatment time of the patient, and is quite inconvenient.

[0044] In this embodiment, when in use, the fixing cover 301 is sleeved on the outer surface of the catheter body 1 and the articulator body 2, so that the catheter body 1 and the articulator body 2 pass through the fixing hole 404, and then the binding belt 303 at the upper left corner is wound from the position above the ear to the back of the patient's head, and then the binding belt 303 at the upper right corner is also wound around the back of the patient's head and covered on the binding belt 303 at the upper left corner, so that the Velcro fur surface 305 is attached to the Velcro hook surface 304, and the connection of the upper set of binding belts 303 is completed. Repeat the above operation process, and the lower set of binding belts 303 are wound from the lower ear to the position behind the patient's head for connection, so that the fixing cover 301 is fixed to the patient's mouth, and the soft cushion 306 is soft to prevent the fixing cover 301 from causing discomfort to the patient's skin. Under the action of the basic fixing component 3, the catheter body 1 and the articulator body 2 can be more firmly fixed to the patient's mouth, and there is no need to use adhesive tape to directly stick them on the patient's face to avoid irritation to the patient's skin. Then, the catheter body 1 and the articulator body 2 can be fixed together through the connection and fixing component 4. By rotating the threaded cover 431, it rotates upward on the outer surface of the connection cover 401, driving the threaded ring 432 to rotate upward in the thread groove 308. When the top of the threaded cover 431 contacts the bottom of the fixing block 402, the threaded ring 432 is completely screwed out of the thread groove 308, and the connection and fixing component 4 can be separated from the basic fixing component 3. When part of the structure is damaged, a certain component can be replaced separately, and all of them do not need to be replaced, which improves the utilization rate of the connection and fixing component 4 and the basic fixing component 3 and reduces resource waste.

[0045] The usage and working principle of the present invention are as follows: pull the two adjustment shafts 422 upward at the same time, drive the multiple elastic clamping rods 423 to move upward together, so that the elastic clamping ball at one end of the elastic clamping rod 423 is pulled out from the clamping sleeve 424. When the sound of the elastic clamping ball being pulled out is heard, stop pulling the adjustment shaft 422. At this time, the two movable gears 421 are driven by the adjustment shaft 422 to move upward together, from the middle position inside the tightening gear 419 to the upper position. Then, the two adjusting shafts 422 are rotated to drive the multiple elastic clamping rods 423 to rotate above the clamping sleeve 424, and drive the two movable gears 421 to rotate together, and further drive the two tightening gears 419 to rotate, and respectively wind and tighten the first tightening rope 409 and the second tightening rope 414. As the first tightening rope 409 and the second tightening rope 414 are tightened, the square moving plate 405 and the arc moving plate 410 are driven to move relative to each other, and the reset plate 415 is driven to move, so that the reset spring 416 is squeezed and contracted together. At the same time, the square fixing clamp 407 and the arc fixing clamp 412 are driven to move relative to each other through the first connecting rod 406 and the second connecting rod 411, so that the square rubber pad 408 and the articulator are engaged. The outer surface of the main body 2 is in contact, and the arc-shaped rubber pad 413 is in contact with the outer surface of the catheter body 1. As the first tightening rope 409 and the second tightening rope 414 are further tightened, the square fixing clamp 407 and the arc-shaped fixing clamp 412 respectively clamp the articulator body 2 and the catheter body 1 together, and finally press the two adjustment shafts 422 downward to push the elastic clamping rod 423 to be clamped into the clamping sleeve 424 again, and the movable gear 421 moves to the middle of the tightening gear 419 again. Through the cooperation of the elastic clamping rod 423 and the clamping sleeve 424, the adjusting shaft 422 and the movable gear 421 are limited, thereby limiting the two tightening gears 419 after tightening to complete the fixation between the catheter body 1 and the articulator body 2. When it is necessary to remove the catheter body 1, pull the two adjusting shafts 422 upward again to pull the elastic clamping rod 423 out of the clamping sleeve 424, and continue to pull the adjusting shaft 422 upward so that the elastic clamping rod 423 enters the inner groove 427 and contacts the top surface inside the inner groove 427. When the adjusting shaft 422 can no longer be pulled, the movable gear 421 is completely moved out from the tightening gear 419, and the reset spring 416 begins to rebound, pushing the reset plate 415 to move in the opposite direction and reset, while driving the square movable plate 405 and the arc movable plate 410 to move in the opposite direction and reset, further pulling the first tightening rope 409 and the second tightening rope 414 to move, thereby driving the two tightening gears 419 to rotate, and releasing the first tightening rope 409 and the second tightening rope 414. While the square movable plate 405 and the arc-shaped movable plate 410 move, the square fixing clamp 407 and the arc-shaped fixing clamp 412 are driven to move in the opposite direction by the first connecting rod 406 and the second connecting rod 411, thereby releasing the clamping fixation of the catheter body 1 and the articulator body 2.Under the action of the connection and fixing component 4, by pulling the adjustment shaft 422, the clamping and fixing of the catheter body 1 can be automatically loosened, which is convenient for medical staff to take out the catheter body 1. The operation is simple and convenient, saving time, and the patient can be treated faster. The fixed cover 301 is put on the outer surface of the catheter body 1 and the articulator body 2, and then the binding belt 303 in the upper left corner is wound from the position above the ear to the back of the patient's head, and then the binding belt 303 in the upper right corner is also wound around the back of the patient's head and covered on the binding belt 303 in the upper left corner, so that the Velcro fur surface 305 is attached to the Velcro hook surface 304, and the connection of the upper group of binding belts 303 is completed. Repeat the above operation process, and the lower group of binding belts 303 are wound from the lower ear to the position behind the patient's head for connection, so that the fixed cover 301 is fixed at the patient's mouth. The soft pad 306 is soft to prevent the fixed cover 301 from causing discomfort to the patient's skin. There is no need to use adhesive tape to directly stick it on the patient's face to avoid irritation to the patient's skin. By rotating the threaded cover 431, the threaded ring 432 is driven to rotate upward in the threaded groove 308. When the top of the threaded cover 431 contacts the bottom of the fixing block 402, the threaded ring 432 is completely screwed out of the threaded groove 308, and the connecting fixing component 4 can be separated from the basic fixing component 3. When part of the structure is damaged, one component can be replaced separately without replacing all of them.
