Description

Technical Field

[0001] This utility model relates to the field of tube-blocking devices, specifically a tube-blocking device for tracheotomy. Background Technology

[0002] Tracheostomy is a commonly used emergency technique in clinical practice, usually performed when the airway is obstructed or normal breathing is impossible. By cutting open the trachea in the patient's neck and inserting a tracheostomy tube, a direct breathing channel is provided, ensuring oxygen supply and preventing respiratory failure. Once the patient's condition stabilizes and respiratory function recovers, the tracheostomy tube will be removed. However, before extubation, a trial of endotracheal occlusion must be performed to encourage the patient to establish a normal airway ventilation pattern, i.e., breathing through the mouth and nose, no longer relying on the tracheostomy tube at the tracheostomy site. This ensures that the patient's cardiopulmonary function can operate normally after the tracheostomy tube is removed.

[0003] Currently, there is no standardized, dedicated tube-closing device for patients requiring tracheostomy tube occlusion in clinical practice. Medical staff in various departments often improvise tube-closing devices using readily available materials, then seal the tracheostomy tube from the inside or outside of the end. Materials used for these improvised devices include: fat emulsion, amino acid, and glucose injection ports, Murphy drip tubes, heparin caps, disposable drainage bags, protective caps for enteral nutrition infusion sets, syringe plungers, infusion bags, corks, application patches, disposable latex urinary catheter valve sections, disposable ventilator circuit extension caps, and gastric tube caps, among others.

[0004] However, homemade airway blockers made from the aforementioned materials typically require visual estimation of the inner or outer diameter of the tube, followed by repeated adjustments on-site to achieve the desired blockage. Both external and internal blockages completely seal the artificial airway. However, for some patients with prolonged tracheotomy, complete closure of the artificial airway at once can easily cause breathing difficulties, decreased lung ventilation, and hypoxemia due to long-term reliance on the artificial airway. In severe cases, it can even lead to suffocation, necessitating a second tracheotomy. This not only increases patient suffering but also makes the second tracheotomy more difficult and riskier than the first. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a tracheostomy tube blocking device, which can progressively block the tracheostomy tube, facilitating disease recovery and successful extubation.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a tracheotomy tube plugging device, comprising an externally threaded tube, one end of which is connected to an insertion component for inserting a sleeve, and the other end of which is connected to a fixing plate. The top of the fixing plate has a sliding groove communicating with the externally threaded tube, and two opposing stops for opening and closing the opening of the externally threaded tube are slidably connected in the sliding groove. A rotating ring is threadedly connected to the externally threaded tube, and a rotating groove is opened on the rotating ring. The bottom of the fixing plate has two sliding holes corresponding to the stops, and two transmission components that pass through the sliding holes and are connected to the stops are slidably connected on the rotating groove. Rotating the rotating ring drives the transmission components to move the stops closer to or further away from each other on the sliding groove.

[0009] Furthermore, the transmission assembly includes a connecting rod, one end of which is rotatably connected to a connecting frame that is connected to a stop block, and the other end of which is rotatably connected to a slider that is slidably connected to a slide groove.

[0010] Furthermore, the insertion component includes a cannula, the outer wall of which has multiple annular grooves, and anti-slip rings are provided in the grooves.

[0011] Furthermore, a limiting ring for upper limit positioning of the sleeve is provided on the outer wall of the insert near the external threaded tube.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a tracheostomy tube occlusion device, which has the following beneficial effects:

[0014] This tracheostomy tube-blocking device uses a rotating ring to drive a sliding block to connect a connecting rod. The connecting rod then slides along a groove on a fixed plate via a connecting bracket stop. This allows the two stops to gradually block the opening of the externally threaded tube as needed, which is beneficial for the patient's recovery and facilitates successful tube removal.

[0018] 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.

[0019] Please see Figure 1-2 The present invention discloses a tracheotomy tube plugging device, comprising an externally threaded tube 1, one end of which is connected to an insertion component 3 for inserting a sleeve, and the other end is connected to a fixing plate 2. The top of the fixing plate 2 has a sliding groove 4 that communicates with the externally threaded tube 1, and two cross-shaped stops 5 that are used to open and close the opening of the externally threaded tube 1 are slidably connected in the sliding groove 4. A rotating ring 6 is threadedly connected to the externally threaded tube 1, and a T-shaped rotating groove 7 is opened on the top end face of the rotating ring 6. The bottom of the fixing plate 2 has two sliding holes that correspond to the stops 5 respectively, and two transmission components 8 that pass through the sliding holes and are connected to the stops 5 are slidably connected on the rotating groove 7.

[0020] The transmission assembly 8 includes a connecting rod 9, with connecting holes at both ends. A connecting frame 10 is installed on one end of the connecting hole. The connecting frame 10 is U-shaped and has a first connecting shaft that passes through the connecting hole, so that the connecting rod 9 and the connecting frame 10 are rotatably connected. A slider 11 is installed on the other end of the connecting hole. The lower part of the slider 11 is T-shaped and is placed in the slide groove 4, and can slide in the slide groove 4. The upper part is provided with a U-shaped groove, and a second connecting shaft connected to the slider 11 is provided in the U-shaped groove. The second connecting shaft is placed in the connecting hole of the connecting rod 9 and can rotate.

[0021] By rotating the rotating ring 6, the slider 11 is driven to rotate in the rotating groove 7, shortening or increasing the distance between the rotating ring 6 and the fixed plate 2, so that the connecting rod 9 rotates on the slider 11 and the connecting frame 10, driving the stop block 5 to slide in the sliding groove 4, which is used to open and close the pipe opening of the external threaded pipe 1.

[0022] The insertion component 3 includes a tube 12, one end of which is fixedly connected to the external threaded tube 1. The outer wall of the tube 12 has multiple annular grooves, and the grooves are provided with rubber anti-slip rings 13. A limit ring 14 is fixedly connected to the outer wall of the tube 12 near the external threaded tube 1.

[0023] When the insertion tube 12 is inserted into the sleeve, the anti-slip ring 13 is deformed by the compression of the insertion tube 12 and the sleeve, so that the device is firmly installed on the sleeve. The limiting ring 14 limits the depth of the insertion tube 12 into the sleeve, preventing the external thread tube 1 from entering the sleeve, thereby facilitating the rotation of the rotating ring 6.

[0024] In summary, when using this tracheostomy tube occlusion device, the intubation tube 12 is inserted into the tracheostomy tube at the patient's incision site until the limiting ring 14 contacts the end of the tracheostomy tube.

[0025] Then, rotate the rotating ring 6 on the external threaded pipe 1. The rotating ring 6 moves along the external threaded pipe 1, while the slider 11 slides in the rotating groove 7 of the rotating ring 6. As the distance between the rotating ring 6 and the fixed plate 2 changes, the connecting rod 9 rotates on the slider 11 and the connecting bracket 10, causing it to tilt and push the stop block 5 to slide in the sliding groove 4 of the fixed plate 2. Adjust the distance between the two stop blocks 5, thereby adjusting the area of ​​the two stop blocks 5 covering the opening of the external threaded pipe 1, so as to gradually seal the external threaded pipe 1 according to the usage requirements.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
