Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of tracheal fixation devices, specifically referring to a tracheal fixation device that can prevent occult aspiration. Background Technology
[0002] Aspiration is divided into overt aspiration and covert aspiration. Overt aspiration is more obvious, and patients will have a series of obvious symptoms such as coughing, choking, and gagging when it occurs, which is easy to diagnose clinically. However, covert aspiration, which has a higher incidence, is generally difficult to detect because patients have atypical accompanying symptoms and is often missed due to difficulty in diagnosis.
[0003] Currently in clinical practice, it is difficult to determine whether there is a latent aspiration in the trachea based on the insertion of the endotracheal tube, and it is difficult to provide a prompt when the endotracheal tube is in place; furthermore, food or sputum adsorbed on the trachea cannot be effectively cleaned, which can easily lead to blockage and make it impossible to complete the entire process of cleaning and adsorption. Therefore, there is a need to propose an endotracheal fixation device that can prevent latent aspiration. Summary of the Invention
[0004] In order to overcome the shortcomings of the prior art, the present invention provides a tracheal fixation device that can prevent latent aspiration, effectively solving the problems that existing tracheal fixation devices cannot perform a complete series of cleaning and adsorption operations, and that it is difficult to determine whether there is a latent aspiration state in the trachea by the insertion of the tracheal tube.
[0005] The technical solution adopted by the present invention is as follows: The present invention provides a tracheal fixation device that can prevent latent aspiration, including a negative pressure generating component, a tracheal fixation body, a side fixing frame, a tracheal body and a bottom adsorption tube. The negative pressure generating component is disposed on the tracheal fixation body, the side fixing frame is disposed on the tracheal fixation body, the tracheal body is disposed on the side fixing frame, and the bottom adsorption tube is connected to the tracheal fixation body. An adjustment strap is provided on the outer wall of the tracheal fixation body for better fixation of the device.
[0006] Preferably, the negative pressure generating component includes an auxiliary spring, a spring base, a lower spring support, a connecting support, a capillary tube, a support frame, a top limiting plate, a piston rod, a piston plate, an internal delivery chamber, and a bottom opening. The lower spring support is connected to the top of the airway fixing body, the connecting support is connected to the top of the lower spring support, the spring base is fixed to the lower spring support, the support frame is embedded in the connecting support, the top limiting plate is fixed to the top of the support frame and the connecting support, a positioning hole is provided through the top limiting plate, the piston rod is fixed to the positioning hole, the piston plate is fixed to the bottom of the piston rod, the auxiliary spring is located between the spring base and the top limiting plate, the internal delivery chamber is located in the airway fixing body, the bottom opening is located on the side wall of the bottom adsorption tube, the capillary tube is located in the internal delivery chamber, and the capillary tube is connected between the connecting support and the bottom opening.
[0007] Furthermore, the tracheal fixation body includes a negative pressure generating container and a drainage tube. The negative pressure generating container is fixed to the side fixing frame, and the drainage tube is connected to the side wall of the negative pressure generating container to discharge the adsorbed hidden blockage.
[0008] The spring's lower support is connected to the top of the negative pressure generating container.
[0009] Furthermore, the piston plate is fitted and slidably disposed within the negative pressure generating container.
[0010] The internal conveying chamber is located on the connecting support, the support below the spring, the negative pressure generating container, and the bottom adsorption tube.
[0011] Preferably, the internal delivery chamber and capillary tubes are arranged in several groups to absorb and deliver excess fluid in the patient's esophagus from multiple angles.
[0012] Furthermore, the adjustment belt is equipped with an adjustment knob and an adjustment hole, and the adjustment knob and adjustment hole are matched.
[0013] Furthermore, the connecting support is made of water-soluble paper, which can absorb and transport excess liquid in the patient's esophagus through capillary tubes. The connecting support absorbs the liquid in the capillary tubes a second time. After the connecting support melts, it can no longer restrict the extension and contraction of the auxiliary spring through the support frame. The auxiliary spring drives the piston rod and piston plate to move upward through the top limiting plate, so that negative pressure is generated in the negative pressure generating container. Negative pressure is formed at the bottom opening of the bottom adsorption tube, thereby adsorbing the hidden blockage in the patient's esophagus and preventing the patient's lung infection.
[0014] The bottom of the support frame does not contact the support component below the spring, so that after the connecting support component melts, it drives the top limiting piece to move upward through the auxiliary spring.
[0015] The beneficial effects achieved by the present invention using the above structure are as follows: This solution provides a tracheal fixation device that can prevent latent aspiration, effectively solving the problems of existing tracheal fixation devices being unable to perform a complete series of cleaning and adsorption operations, and the difficulty in determining whether latent aspiration exists in the trachea based on the insertion status of the tracheal tube. This method brings the following advantages: (1) This invention proposes a negative pressure generating component. The capillary can absorb and transport excess liquid in the patient's esophagus. The connecting support can absorb the liquid in the capillary a second time. The connecting support made of water-soluble paper cannot restrict the extension and contraction of the auxiliary spring through the support skeleton after melting. The auxiliary spring can generate an upward restoring force. The auxiliary spring can drive the piston rod and piston plate to move upward through the top limiting plate, so that negative pressure is generated in the negative pressure generating container. Negative pressure is formed at the bottom opening of the bottom adsorption tube, thereby adsorbing the hidden blockage in the patient's esophagus and preventing the patient's lung infection. The hidden blockage enters the negative pressure generating container through the bottom adsorption tube. The hidden blockage can be discharged and cleaned through the drainage tube, thereby realizing a series of complete operations of cleaning and adsorption, effectively preventing the hidden aspiration of critically ill patients in an unconscious state, and providing an automated experience. (2) Several sets of internal transport chambers and capillary tubes surround the esophagus to absorb and transport excess fluid from multiple angles; (3) The bottom of the support frame does not contact the support component below the spring, so that after the connecting support component melts, the top limiting piece moves upward through the auxiliary spring.

Therefore, they should not be construed as limitations on this invention.
[0021] like Figure 1 , Figure 2 and Figure 7 As shown, the present invention provides a tracheal fixation device for preventing latent aspiration, including a negative pressure generating component 1, a tracheal fixation body 2, a side fixing frame 3, a tracheal body 4, and a bottom adsorption tube 5. The negative pressure generating component 1 is disposed on the tracheal fixation body 2, the side fixing frame 3 is disposed on the tracheal fixation body 2, the tracheal body 4 is disposed on the side fixing frame 3, and the bottom adsorption tube 5 is connected to the tracheal fixation body 2. An adjustment strap 6 is provided on the outer wall of the tracheal fixation body 2 for better fixation of the device.
[0022] like Figures 1-6As shown, the negative pressure generating component 1 includes an auxiliary spring 7, a spring base 8, a lower spring support 9, a connecting support 10, a capillary tube 11, a support frame 12, a top limiting plate 13, a piston rod 14, a piston plate 15, an internal delivery chamber 16, and a bottom opening 17. The lower spring support 9 is connected to the top of the air pipe fixing body 2, and the connecting support 10 is connected to the top of the lower spring support 9. The spring base 8 is fixed to the lower spring support 9, and the support frame 12 is embedded in the connecting support 10. The top limiting plate 13... The top of the plate 13 is fixedly connected to the support frame 12 and the connecting support member 10. The top limiting plate 13 is provided with a positioning hole 18. The piston rod 14 is fixedly connected to the positioning hole 18. The piston plate 15 is fixedly connected to the bottom of the piston rod 14. The auxiliary spring 7 is located between the spring base 8 and the top limiting plate 13. The internal delivery chamber 16 is located in the air tube fixing body 2. The bottom opening 17 is opened on the side wall of the bottom adsorption tube 5. The capillary tube 11 is located in the internal delivery chamber 16. The capillary tube 11 is connected between the connecting support member 10 and the bottom opening 17.
[0023] like Figure 1 , Figure 2 and Figure 4 As shown, the tracheal fixation body 2 includes a negative pressure generating container 19 and a drainage tube 20. The negative pressure generating container 19 is fixed to the side fixing frame 3, and the drainage tube 20 is connected to the side wall of the negative pressure generating container 19 for discharging adsorbed hidden blockages.
[0024] like Figure 2 and Figure 6 As shown, the spring-lower support 9 is connected to the top of the negative pressure generating container 19; the internal conveying cavity 16 is connected to the support 10, the spring-lower support 9, the negative pressure generating container 19 and the bottom adsorption tube 5.
[0025] like Figure 2 and Figure 3 As shown, the piston plate 15 is fitted and slidably disposed in the negative pressure generating container 19.
[0026] like Figure 6 and Figure 8 As shown, the internal delivery chamber 16 and capillary tubes 11 are arranged in several groups to absorb and deliver excess fluid in the patient's esophagus from multiple angles.
[0027] like Figure 7 As shown, the adjustment belt 6 is provided with an adjustment knob 21 and an adjustment hole 22, and the adjustment knob 21 and the adjustment hole 22 are matched.
[0028] like Figures 2-6As shown, the connecting support 10 is made of water-soluble paper. It can absorb and transport excess liquid in the patient's esophagus through the capillary tube 11. The connecting support 10 absorbs the liquid in the capillary tube 11 a second time. After the connecting support 10 melts, it can no longer restrict the extension and retraction of the auxiliary spring 7 through the support frame 12. The auxiliary spring 7 drives the piston rod 14 and piston plate 15 to move upward through the top limiting plate 13, so that negative pressure is generated in the negative pressure generating container 19. Negative pressure is formed at the bottom opening of the bottom adsorption tube 5, thereby adsorbing the hidden blockage in the patient's esophagus and preventing the patient's lung infection.
[0029] like Figure 5 and Figure 6 As shown, the bottom of the support frame 12 does not contact the support member 9 below the spring, so that after the connecting support member 10 melts, it drives the top limiting piece 13 to move upward through the auxiliary spring 7.
[0030] In practical use, first position the device above the patient's head using the adjustment knob 21 and adjustment hole 22 on the adjustment belt 6. Then, insert the trachea body 4 into the appropriate position through the trachea fixing body 2, allowing the bottom suction tube 5 to enter the patient's esophagus. When the excess liquid in the patient's esophagus accumulates to the height of the bottom opening 17, it indicates that the patient is experiencing latent aspiration. If left untreated for a long time, it can easily lead to lung infection. At this time, the capillary tube 11 can absorb and transport the excess liquid in the patient's esophagus. The connecting support 10 performs secondary absorption of the liquid in the capillary tube 11. After the water-soluble paper connecting support 10 melts, it cannot restrict the extension and retraction of the auxiliary spring 7 through the support frame 12. The auxiliary spring 7 can generate an upward restoring force, which in turn can drive the piston rod 14 through the top limiting plate 13. The piston plate 15 moves upward, creating negative pressure in the negative pressure generating container 19. This negative pressure forms at the bottom opening of the bottom adsorption tube 5, thereby adsorbing hidden blockages in the patient's esophagus and preventing lung infection. The hidden blockages enter the negative pressure generating container 19 through the bottom adsorption tube 5 and can be discharged and cleared through the drainage tube 20, thus realizing a complete series of operations of cleaning and adsorption. This effectively prevents hidden aspiration in critically ill patients who are unconscious or otherwise in an automated state. Several sets of internal delivery chambers 16 and capillaries 11 surround the area, allowing for the absorption and delivery of excess liquid in the patient's esophagus from multiple angles. The bottom of the support frame 12 does not contact the support member 9 below the spring, so that after the connecting support member 10 melts, it drives the top limiting plate 13 to move upward through the auxiliary spring 7.
