[0048] The quick-release cleaning component 11 is located above the external support frame 3. The quick-release cleaning component 11 is used to clean and absorb secretions generated in the trachea.

[0049] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 In a preferred embodiment, the quick-release cleaning assembly 11 includes:

[0050] Fixed tube 1101, the bottom end of fixed tube 1101 is fixedly connected to the top end of external support frame 3;

[0051] The bottom end of the visible tube 1102 is fixedly connected to the top end of the fixed tube 1101. The visible tube 1102 is connected to the fixed tube 1101, and the top end of the visible tube 1102 is an open end.

[0052] An extension tube 1106 is positioned above the visible tube 1102. One end of the extension tube 1106 is fixedly connected to a connecting pipe 1104, and the other end of the extension tube 1106 is fixedly connected to a fixed bottom tube 1107. The top end of the connecting pipe 1104 is detachably connected to the open end of the visible tube 1102 via a connector 1105. The extension tube 1106 is connected to the fixed bottom tube 1107 and the connecting pipe 1104.

[0053] The controller 1108 is located on one side of the fixed bottom tube 1107. The bottom end of the controller 1108 is fixedly connected to the secretion collection box 1111, and the top end of the secretion collection box 1111 is fixedly connected to the bottom end of the fixed bottom tube 1107.

[0054] In this invention, the quick-release cleaning assembly 11 further includes:

[0055] A sealing head 1103 is disposed inside the bottom end of the visible tube 1102 and is used to seal the visible tube 1102.

[0056] A connecting pipe 1104 is provided at the bottom end of the sealing head 1103. The bottom end of the connecting pipe 1104 is fixedly connected to the top end of the extension movable pipe 1106. The connecting pipe 1104 and the extension movable pipe 1106 are connected.

[0057] A negative pressure pump 1109 is fixedly connected to the top of the secretion collection box 1111. The suction end of the negative pressure pump 1109 is fixedly connected to a negative pressure tube 1110. A round hole is opened on the outside of the secretion collection box 1111. The bottom outer side of the negative pressure tube 1110 is fixedly connected to the inside of the round hole. The negative pressure tube 1110 is connected to the secretion collection box 1111.

[0058] In this invention, a connector 1105 is fixedly connected to the outside of the connecting pipe 1104. The top end of the connector 1105 is threaded to the bottom end of the visible tube 1102, and the sealing head 1103 is located inside the connector 1105. Multiple obliquely arranged elastic paddles 1112 are fixedly connected inside the connecting pipe 1104 to form a one-way valve structure.

[0059] In specific application scenarios, medical staff observe the inside of the patient's trachea through the visual tube 1102. When blood clots or sputum are seen inside, the sealing head 1103 inside the visual tube 1102 is removed. The connecting pipe 1104 is kept connected to the visual tube 1102 through the connector 1105. The negative pressure pump 1109 is started through the controller 1108. The negative pressure pump 1109 creates negative pressure inside the visual tube 1102 through the negative pressure pipe 1110. Under the action of negative pressure, the blood clots and sputum in the patient's trachea are adsorbed into the secretion collection box 1111 through the visual tube 1102 and the connecting pipe 1104. During this process, the elastic flap 1112 inside the connecting pipe 1104 prevents the adsorbed blood clots and other secretions from flowing back. The extension tube 1106 can be adjusted in length and position according to the patient's specific situation, such as body position and tracheal position, in order to better carry out the cleaning operation.

[0060] Specifically, the visual tube 1102 allows for direct observation of obstructions such as sputum and blood clots in the trachea. Connecting the tube 1104 and activating the negative pressure pump 1109 creates negative pressure, quickly drawing sputum, blood clots, etc., into the secretion collection box 1111, preventing them from accumulating in the tube and causing blockage, thus maintaining smooth ventilation.

[0061] It should be noted that the extension tube 1106 can be flexibly adjusted in length and position according to the patient's body and tracheal position, which can better target and clear the obstruction site, ensuring that all possible obstruction sites inside the cannula can be effectively cleared, thus ensuring normal ventilation function.

[0062] Reference Figure 1 , Figure 2 , Figure 3, Figure 4 , Figure 7 and Figure 8 In a preferred embodiment, the snap-fit ​​separation and debridement component 7 includes:

[0063] Arc-shaped clamp 701 is located on the outside of threaded connecting pipe 2;

[0064] An arc-shaped buckle 702 is provided on the outside of the threaded connecting pipe 2. Both ends of the arc-shaped buckle 701 have grooves inside, and both ends of the arc-shaped buckle 702 are engaged inside the grooves.

[0065] Two arc-shaped sliding plates 704 are both located below the arc-shaped snap connector 701 and the arc-shaped buckle 702. Arc-shaped sliding grooves are provided on the arc-shaped sliding plates 704, and sliding seats 706 are slidably connected inside the arc-shaped sliding grooves.

[0066] The cotton roller 708 is located below the sliding seat 706, and the outer side of the cotton roller 708 is in contact with the tracheal wound.

[0067] In this invention, the snap-fit ​​separation and debridement component 7 further includes:

[0068] The wound cleaning medicine box 713 is located above the sliding seat 706. A micro pump 712 is fixedly connected to the front end of the wound cleaning medicine box 713, and a medicine tube 710 is fixedly connected to the output end of the micro pump 712.

[0069] The medicine soaking tube 709 is movably connected to the inside of the cotton roller 708. The end of the medicine soaking tube 709 away from the threaded connecting tube 2 is fixedly connected to the bottom end of the medicine tube 710, and the medicine soaking tube 709 and the medicine tube 710 are connected. The medicine soaking tube 709 has multiple soaking ports.

[0070] Manual moving part 705 is fixedly connected to the top of sliding base 706.

[0071] In this invention, the bottom ends of the arc-shaped snap connector 701 and the arc-shaped buckle 702 are both fixedly connected to the extension frame 703. The bottom ends of the extension frame 703 are both fixedly connected to the top end of the arc-shaped sliding plate 704. The top end of the sliding seat 706 is fixedly connected to the bottom frame 711. The top end of the bottom frame 711 is fixedly connected to the bottom end of the wound cleaning medicine box 713. The bottom end of the sliding seat 706 is fixedly connected to the connecting frame 707. The inner side of the bottom end of the connecting frame 707 is fixedly connected to both ends of the medicine soaking tube 709. The connecting frame 707 has a hole on the side away from the threaded connecting tube 2. The outer side of the medicine tube 710 is fixedly connected to the inside of the hole.

[0072] In specific application scenarios, when it is necessary to regularly disinfect and clean a patient's tracheal wound, first, fix the arc-shaped clamp connector 701 and the arc-shaped buckle 702 to the outside of the threaded connecting pipe 2. Utilizing the cooperation between the grooves at both ends of the arc-shaped clamp connector 701 and the ends of the arc-shaped buckle 702, the snap-on separation debridement component 7 is quickly and securely installed. Then, start the micro pump 712. Under the action of the micro pump 712, the medicine inside the debridement medicine tank 713 flows into the medicine infiltration tube 709 through the medicine infiltration tube 710. Since the medicine infiltration tube 709 and the medicine infiltration tube 710 are connected, the medicine can smoothly reach the medicine infiltration tube 709. The cotton roller 708 is movably connected to and in contact with the medicine soaking tube 709. It absorbs the medicine seeping from the multiple soaking ports on the medicine soaking tube 709, making itself saturated with disinfectant. Medical staff operate the manual moving part 705 to drive the sliding seat 706 to slide in the arc-shaped groove of the arc-shaped sliding plate 704. When the sliding seat 706 moves, the bottom frame 711 connected to it drives the wound cleaning medicine box 713, the connecting frame 707 drives the medicine soaking tube 709, and the cotton roller 708 also moves. During the movement, the cotton roller 708, which is saturated with medicine, comes into contact with the tracheal wound to wipe, clean and disinfect the wound.

[0073] Specifically, the cotton roller 708 comes into direct contact with the wound, and together with the medicine seeping from the medicine soaking tube 709, it can effectively remove dirt from the wound and disinfect it at the same time, reducing the risk of infection. In addition, the cotton roller 708 is made of soft material and is gentle when it comes into contact with the wound, reducing irritation and discomfort to the patient's wound and improving the patient experience.

[0074] It should be noted that the arc-shaped connector 701, arc-shaped buckle 702, and extension frame 703 form a stable structure, ensuring that the components will not shake or fall off during use, thus guaranteeing operational safety.

[0075] Reference Figures 1-4 In a preferred embodiment, rectangular holes are provided at both ends of the external support frame 3, and fixed rings 4 are fixedly connected inside the rectangular holes. The opposite sides of the fixed rings 4 are fixedly connected to one end of the flexible straps 5. Velcro 6 is fixedly connected to the ends of the two flexible straps 5 away from the fixed rings 4. A connecting ring 10 is fixedly connected to the outside of the threaded connecting tube 2. The connecting ring 10 is connected to the threaded connecting tube 2. A drug inlet tube 8 is fixedly connected to the outside of the connecting ring tube 10. A drug inlet 9 is fixedly connected to the top of the drug inlet tube 8. The drug inlet 9 is connected to the drug inlet tube 8.

[0076] Working principle: When using the tracheostomy device, the inner tube 1 is inserted into the patient's tracheostomy incision. One end of the flexible strap 5 is fixed through the fixing rings 4 in the rectangular holes at both ends of the external support frame 3. Then, the Velcro 6 at both ends of the flexible strap 5 is wrapped around the back of the patient's neck and fixed, so that the entire device is securely worn on the patient's neck and the device will not shift during use.

[0077] If it is necessary to inject medication into the patient's trachea, the medication can be poured in through the inlet 9, through the inlet tube 8 and the connecting ring tube 10, and finally flow into the threaded connecting tube 2, thus penetrating deep into the patient's trachea;

[0078] Medical staff observe the patient's trachea through the visual tube 1102. When blood clots or sputum are found inside the visual tube 1102, the sealing head 1103 inside the bottom of the visual tube 1102 is removed first. Then, the connecting pipe 1104 is connected to the visual tube 1102 through the connector 1105. Next, the negative pressure pump 1109 is started through the controller 1108. Under the action of negative pressure, secretions such as blood clots and sputum in the visual tube 1102 are adsorbed and enter the secretion collection box 1111 through the connecting pipe 1104, the extension tube 1106, etc., and through the negative pressure tube 1110. The extension tube 1106 can be flexibly adjusted in length and position to adapt to the tracheal condition of different patients. The elastic flap 1112 in the connecting pipe 1104 can effectively prevent the adsorbed secretions from flowing back and ensure the cleaning effect.

[0079] When it is necessary to disinfect and clean the tracheal wound regularly, first fix the arc-shaped clamp 701 and arc-shaped buckle 702 to the outside of the threaded connecting pipe 2, start the micro pump 712, and deliver the medicine in the wound cleaning medicine box 713 to the medicine soaking tube 709 through the medicine pipe 710. After the cotton roller 708 absorbs the medicine seeping from the soaking port on the medicine soaking tube 709, the medical staff operates the manual moving part 705 to drive the sliding seat 706 to slide in the arc-shaped groove of the arc-shaped sliding plate 704, so that the cotton roller 708 full of medicine contacts and moves with the tracheal wound, realizing the wiping, cleaning and disinfection of the wound.

[0080] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
