Abstract
Description
Technical Field
[0001] This utility model relates to the field of tracheostomy device technology, and more specifically to a tracheostomy cannula plugging cap training device. Background Technology
[0002] A tracheostomy tube is a medical device used to maintain airway patency after tracheostomy. It is suitable for long-term mechanical ventilation, upper airway obstruction, or airway secretion management. Common tracheostomy tubes typically have only two modes of occlusion: "fully open" or "fully closed." The trachea must be closed before extubation. In this mode, the patient's trachea may not adapt to full occlusion immediately, potentially causing discomfort.
[0003] Clinically, to address this issue, endotracheal cannula occlusion caps, such as those disclosed in prior art publication CN222517486U, are used. These caps allow for adjustment of the air intake before extubation, helping patients gradually adapt to the complete endotracheal occlusion process. However, these caps are generally made of plastic and are disposable. Their complex design increases manufacturing difficulty and cost, potentially adding to the financial burden of treatment for patients.
[0004] Although some metal caps can be reused, they must be thoroughly disinfected after each use before they can be reused. Caps with complex structural designs are prone to creating blind spots for disinfection and cleaning, leading to increased disinfection time and costs. Utility Model Content
[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a tracheostomy tube plugging cap trainer. Through a detachable design, a reusable piston, hollow cylinder, and plug are installed inside the plugging cap, enabling air volume adjustment while reducing the difficulty of cleaning and disinfection. This helps to shorten disinfection time, reduce disinfection costs, and lower treatment expenses for patients, thereby solving the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a tracheostomy tube plugging cap trainer, including a tracheostomy tube connector fixed to the top of the tracheostomy tube, wherein a plugging cap for sealing the tracheostomy tube is threadedly connected to the outer wall of the top of the tracheostomy tube connector, and the plugging cap is provided with multiple through holes a, through which air enters the interior of the tracheostomy tube;
[0007] The sealing cap is detachably connected to a venting regulating plug for adjusting the air intake in the sleeve.
[0008] The venting regulating plug includes a hollow cylinder detachably connected inside the sealing cap. A piston is fixed at the bottom of the hollow cylinder, and a conical hole with a connecting sleeve is opened in the middle of the piston. Multiple through holes b with connecting conical holes and through hole a are opened on the outer wall of the hollow cylinder. A plug that matches the conical hole is provided inside the conical hole. After the plug moves up, air passes through through hole a and through hole b in sequence and enters the hollow cylinder. Then, it enters the sleeve through the gap between the conical hole and the plug. The air intake in the sleeve is proportional to the size of the gap between the conical hole and the plug. The larger the gap, the larger the air intake.
[0009] In a preferred embodiment, a threaded rod is fixed to the top of the plug, the top of the threaded rod passes through the sealing cap and extends beyond the top of the sealing cap, the outer wall of the threaded rod is connected to the sealing cap by threads, and the rotation of the threaded rod drives the plug to move up and down inside the hollow cylinder to adjust the size of the gap between the tapered hole and the plug.
[0010] In a preferred embodiment, the outer wall of the top of the hollow cylinder is machined with external threads, the top of the inner part of the sealing cap is provided with a groove, the inner wall of the groove is machined with internal threads, and the top of the hollow cylinder and the top of the inner part of the sealing cap are connected together by threads.
[0011] In a preferred embodiment, a sealing ring is embedded at the top of the sealing cap. After the top of the hollow cylinder is installed inside the groove, the sealing ring is squeezed between the hollow cylinder and the inner wall of the sealing cap to seal the gap between the hollow cylinder and the sealing cap, thereby enhancing the sealing performance of this invention.
[0012] In a preferred embodiment, the threaded rod has a handle detachably connected to its tip by a screw, and the handle is located on top of the sealing cap.
[0013] In a preferred embodiment, a fixing plate is fixed to the outer wall of the top end of the cannula. The fixing plate is located at the outer end of the cannula connector. Both ends of the fixing plate are provided with rope holes for connecting a binding rope. The cannula is fixed in the patient's airway by binding rope and fixing plate.
[0014] In a preferred embodiment, the sealing cap is made of plastic and is used as a disposable consumable. The piston, hollow cylinder, plug, threaded rod, and handle are all made of reusable materials, making them reusable and reducing usage costs.
[0015] In a preferred embodiment, the outer diameter of the piston is equal to the inner diameter of the sleeve joint. After the sealing cap is installed at the outer end of the sleeve joint, the piston contacts the inner wall of the sleeve joint. This is used to prevent air from entering the sleeve when the plug seals the tapered hole, thereby achieving the sealing of the air pipe.
[0016] The technical effects and advantages of this utility model are as follows:
[0017] 1. By controlling the raising and lowering of the plug to adjust the amount of air in the conical hole, it is convenient to control the amount of air entering the cannula from large to small before sealing, helping the patient to gradually adapt to full sealing and reducing the patient's discomfort during the sealing process.
[0018] 2. The sealing cap in this utility model is made of plastic, has a simple structure, low manufacturing cost, and can be used as a disposable consumable without the burden of cleaning. Furthermore, through a detachable design, reusable pistons, hollow cylinders, and plugs are installed inside the sealing cap, which reduces the difficulty of cleaning and disinfecting reusable parts while achieving gas volume regulation. This helps to shorten disinfection time, reduce disinfection costs, and help reduce patients' treatment expenses.
[0019] 3. The sealing cap and ventilation regulating plug in this utility model have a simple structural design, which can reduce the manufacturing difficulty while meeting the requirements for adjusting the ventilation volume, thereby further reducing the overall manufacturing cost of this utility model and enhancing its economic applicability.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Refer to the instruction manual appendix Figure 1 and Figure 2 This utility model provides a tracheostomy tube plugging cap training device, including a tracheostomy tube connector 3 fixed to the top of the tracheostomy tube 1, and a fixing plate 2 fixed to the outer wall of the top of the tracheostomy tube 1. The fixing plate 2 is located outside the tracheostomy tube connector 3. Both ends of the fixing plate 2 are provided with rope holes for connecting the binding rope. When establishing an artificial airway for a patient, the tracheostomy tube 1 needs to be inserted from the tracheostomy, and then the fixing plate 2 is attached to the skin of the patient's neck. Then the binding straps at both ends of the fixing plate 2 are wrapped around the outside of the patient's neck, tied, and then fixed to achieve the effect of fixing the tracheostomy tube 1.
[0030] The tracheotomy made by the doctor allows the exchange of air between the outside and the patient's lungs, ensuring the patient's airway is clear. Before removing the tracheostomy tube, the doctor will gradually try to block the tube, forcing the patient to breathe through the mouth and nose. Therefore, this utility model also has a sealing cap 4 for sealing the tracheostomy tube 1 by threading the outer wall of the top of the tracheostomy tube connector 3. The tracheostomy tube 1 can be sealed by screwing on the sealing cap 4.
[0031] When occluding the tube, to avoid discomfort to the patient caused by direct occlusion, such as... Figures 1-6 As shown: This utility model has multiple through holes a6 on the sealing cap 4. Inside the sealing cap 4, there is a detachable air regulating plug 5 for adjusting the air intake in the sleeve 1, so that the air intake in the sleeve 1 can be controlled from large to small during the tube blocking process, so that the patient can gradually adapt to the tube blocking process, thereby reducing the patient's discomfort.
[0032] Specifically, the venting adjustment plug 5 includes a hollow cylinder 53 detachably connected inside the sealing cap 4. A piston 51 is fixed at the bottom of the hollow cylinder 53. A conical hole 52 connecting the sleeve 1 is opened in the middle of the piston 51. A plurality of through holes b57 connecting the conical holes 52 and the through hole a6 are opened on the outer wall of the hollow cylinder 53. A plug 54 adapted to the conical hole 52 is provided inside the conical hole 52. A threaded rod 55 is fixed at the top of the plug 54. The top of the threaded rod 55 passes through the sealing cap 4 and extends out of the top of the sealing cap 4. The outer wall of the threaded rod 55 is connected to the sealing cap 4 by threads.
[0033] Before use, this utility model needs to be assembled. The specific operation is as follows: First, pass the top end of the threaded rod 55 through the inside of the sealing cap 4 so that the top end of the threaded rod 55 can protrude from the top of the sealing cap 4. Then, use screw 58 to fix the handle 56 to the top end of the threaded rod 55. Next, insert the top end of the hollow cylinder 53 through the bottom of the plug 54. The outer wall of the top end of the hollow cylinder 53 of this utility model is machined with external threads, and the top end of the sealing cap 4 is provided with a groove 59. The inner wall of the groove 59 is machined with internal threads. After insertion, the top of the hollow cylinder 53 is screwed into the groove 59, so that the top of the hollow cylinder 53 and the inner top of the sealing cap 4 are connected together by threads, realizing the installation between the hollow cylinder 53 and the sealing cap 4. Moreover, a sealing ring 510 is embedded in the inner top of the sealing cap 4. When the top of the hollow cylinder 53 is installed in the groove 59, the sealing ring 510 can be squeezed between the hollow cylinder 53 and the inner wall of the sealing cap 4, thereby sealing the gap between the hollow cylinder 53 and the sealing cap 4 and enhancing the sealing performance of this utility model.
[0034] When adjusting the ventilation volume inside the cannula 1, the plug 54 can be moved upward inside the hollow cylinder 53 by rotating the threaded rod 55. After the plug 54 moves upward, a gap is formed between it and the conical hole 52. Gas flow between the trachea and air or oxygen can be achieved through this gap, thereby ensuring the patient's airway is unobstructed. Moreover, the size of the gap between the conical hole 52 and the plug 54 can be adjusted by rotating the threaded rod 55. The air intake volume in the cannula 1 is directly proportional to the size of the gap between the conical hole 52 and the plug 54. That is to say, the larger the gap between the plug 54 and the conical hole 52, the more air can enter the patient's airway. Conversely, during the tube blocking operation, the air intake volume in the patient's airway can be controlled from large to small by controlling the plug 54 to move downward inside the hollow cylinder 53, so that the patient can gradually adapt to the tube blocking process.
[0035] Since the outer diameter of the piston 51 in this invention is equal to the inner diameter of the sleeve joint 3, when performing a complete blockage, the plug 54 can be directly screwed into the conical hole 52, so that the gap between the plug 54 and the conical hole 52 is sealed. At this time, the outer wall of the piston 51 contacts the inner wall of the sleeve joint 3, which can also prevent air from entering the sleeve 1 through the gap between the piston 51 and the hollow cylinder 53, thereby blocking air or oxygen from entering the sleeve 1 and achieving a complete blockage of the patient's trachea.
[0036] In the above process, to facilitate the rotation of the threaded rod 55, such as Figure 4 and Figure 5 As shown: A handle 56 is detachably connected to the top of the threaded rod 55 by a screw 58, and the handle 56 is located on the top of the sealing cap 4. During the cannulation process, medical staff can easily rotate the handle 56 from the outside to adjust the height of the plug 54 and the air intake in the cannula 1.
[0037] The sealing cap 4 in this utility model has a simple structure, which can reduce the manufacturing difficulty. The sealing cap 4 is made of plastic and can be used as a disposable consumable, reducing the cost of each use.
[0038] Piston 51, hollow cylinder 53, plug 54, threaded rod 55 and handle 56 are all made of reusable materials. Piston 51 and plug 54 can be made of rubber to ensure sealing, while hollow cylinder 53, threaded rod 55 and handle 56 can be made of metal. The high strength of metal materials can increase the number of times the parts can be used, thereby reducing the cost of each use and alleviating the medical burden on patients.
[0039] After each use, the hollow cylinder 53 and the plug 54 can be disassembled for separate disinfection and cleaning. By disassembling the parts, the complex structure of this utility model is simplified, which can avoid disinfection dead corners, reduce the difficulty and cost of disinfection and cleaning, and further reduce the cost of each use of this utility model, thereby enhancing its economic applicability.
[0040] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
