Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a tube sealing training device. Background Technology

[0002] In clinical treatment, for patients who have undergone tracheotomy, when their condition improves and the tracheostomy tube needs to be removed, tube sealing training is required first. In normal human breathing, airflow enters through the nose, passes through the trachea, and reaches the lungs; however, in tracheotomy patients, airflow enters the lungs directly through the tracheostomy tube. The purpose of tube sealing training is to help patients adapt to inhaling air through the nasal cavity, assess their tolerance for nasal breathing, and thus determine whether they meet the extubation criteria. Currently, common tube sealing training methods often use simple methods such as sealing with wooden or rubber plugs, or directly wrapping and inserting / removing the tube with adhesive tape. These methods have significant drawbacks: they cannot dynamically adjust resistance and require frequent manual operation by medical staff, making it difficult to achieve a precise, programmed training plan. Immediately closing the trachea can cause patients to be unable to adapt, preventing the automatic gradual increase of resistance, making the training effect dependent on the experience of medical staff, and easily causing patient discomfort due to untimely operation. Therefore, there is an urgent need for a tube sealing training device with automated control capabilities that can adjust the rate of airway resistance increase according to a preset training plan.

[0003] Therefore, the existing medical device technology field needs further improvement. Utility Model Content

[0004] The purpose of this invention is to provide a endotracheal closure training device that can adjust the rate of increase of airway resistance to suit different patients, preset training programs according to individual patient differences, gradually reduce the airflow in the trachea, assist patients in completing adaptive training of respiratory muscles, improve the success rate of endotracheal closure, and reduce the workload of medical staff.

[0005] To achieve the above objectives, the present invention adopts the following solution: A tube sealing training device includes a device body, a flexible air tube obliquely disposed within the device body, a movable pressure roller assembly that moves toward the flexible air tube within the device body, a sealed cavity within the device body, an elastic pressure plate on the movable pressure roller assembly capable of compressing the space of the sealed cavity, a gas flow hole on the device body for communicating with the sealed cavity, and a control component on the device body for controlling the size of the gas flow hole.

[0006] Furthermore, the flexible air tube enters from one end of the device body and extends to the lower surface, and the moving pressure roller assembly gradually presses the obliquely arranged flexible air tube in a horizontal direction.

[0007] Furthermore, the movable pressure roller assembly includes a horizontal guide hole disposed on the device body, a horizontal push rod movably disposed in the horizontal guide hole, a wheel seat disposed at the inner end of the horizontal push rod, and a pressure roller installed in the wheel seat.

[0008] Furthermore, the horizontal push rod extends through the sealed cavity, and the elastic pressure plate includes a piston plate disposed on the horizontal push rod. The piston plate is movably disposed within the sealed cavity, and a spring structure is provided between the piston plate and the sealed cavity for pressing the piston plate toward the soft air tube.

[0009] Furthermore, the control component includes a rotating circular groove disposed on the lower surface of the device body, a rotating circular plate rotatably disposed in the rotating circular groove, an arc-shaped opening disposed at the edge of the rotating circular plate, and a gas flow hole disposed at an eccentric position at the center of the rotating circular groove and aligned with the arc-shaped opening.

[0010] Furthermore, a pull ring is provided at the outer end of the horizontal push rod.

[0011] In summary, the advantages of this utility model over the prior art are: This invention addresses the shortcomings in the existing medical device technology field. Through its structural design, it possesses the following advantages: precise resistance adjustment. This invention utilizes a pressure roller assembly to compress the flexible tubing, altering its diameter and adjusting the size of the gas flow orifice, thus creating a dual resistance regulation mechanism. Pre-set training programs can be customized to suit individual patient conditions, such as linear, stepwise, or exponential reduction modes to decrease airflow resistance, achieving progressive training of the respiratory muscles. Automated control reduces the frequency of intervention by medical staff, lowering the risk of infection. By adjusting the rate of increase in airway resistance to suit different patients, and by pre-setting training programs based on individual patient differences, the invention gradually reduces tracheal airflow, assisting patients in completing adaptive training of their respiratory muscles, improving the success rate of tube closure, and reducing the workload of medical staff.

[0013] 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.

[0014] Please see Figures 1-3 This utility model provides a tube sealing training device, including a device body 1, a flexible air tube 2 obliquely arranged inside the device body 1, a movable pressure roller assembly 3 that moves toward the flexible air tube 2 inside the device body 1, a sealed cavity 4 inside the device body 1, an elastic pressure plate 5 that can compress the space of the sealed cavity 4 on the movable pressure roller assembly 3, a gas flow hole 6 for communicating with the sealed cavity 4 on the device body 1, and a control assembly 7 for controlling the size of the gas flow hole 6 on the device body 1. Depending on the different circulation intensities, the control component 7 is adjusted to control the airflow volume of the gas flow hole 6. When the flow volume is smaller, the reset speed of the elastic pressure plate 5 is slower, and the speed at which the moving pressure roller assembly 3 presses down and reduces the ventilation volume of the soft tube 2 is also lower, thereby enabling the patient to gradually adapt to the ability of spontaneous nasal breathing after the soft tube 2 is removed. The front end of the flexible air tube 2 is provided with a connecting sleeve 300 for connecting with an external air tube. The outer end of the horizontal push rod 302 is provided with an external thread, and a limiting sleeve 400 is fitted and threaded onto the external thread. Adjusting the position of the limiting sleeve 400 can limit the stroke of the horizontal push rod 302 and fix the movement of the horizontal push rod 302.

[0015] When the flow rate of the gas flow hole 6 is greater, the reset speed of the elastic pressure plate 5 is faster. This is because the elastic pressure plate 5 needs to discharge the air in the sealed cavity 4 from the gas flow hole 6. Therefore, controlling the size of the gas flow hole 6 can change the speed of air discharge and achieve the purpose of automatically and gradually reducing the flow rate of the soft air tube 2.

[0016] The flexible air tube 2 of this invention enters from one end of the device body 1 and extends to the lower surface. The movable pressure roller assembly 3 gradually presses the obliquely arranged flexible air tube 2 in a horizontal direction.

[0017] The movable pressure roller assembly 3 of this utility model includes a horizontal guide hole 301 disposed on the device body 1, a horizontal push rod 302 movably disposed in the horizontal guide hole 301, a wheel seat 303 disposed at the inner end of the horizontal push rod 302, and a pressure roller 304 installed in the wheel seat 303.

[0018] The horizontal push rod 302 of this utility model extends through the sealed cavity 4. The elastic pressure plate 5 includes a piston plate 501 disposed on the horizontal push rod 302. The piston plate 501 is movably disposed in the sealed cavity 4. A spring structure 502 for pressing the piston plate 501 toward the soft air tube 2 is disposed between the piston plate 501 and the sealed cavity 4.

[0019] The control component 7 of this utility model includes a rotating circular groove 701 disposed on the lower surface of the device body 1, a rotating circular plate 702 rotatably disposed in the rotating circular groove 701, an arc-shaped opening 703 disposed at the edge of the rotating circular plate 702, and a gas flow hole 6 disposed at an off-center position of the center of the rotating circular groove 701 and aligned with the arc-shaped opening 703. Rotating the rotating circular plate 702 and driving the arc-shaped opening 703, the arc-shaped opening 703 and the gas flow hole 6 partially overlap or completely misalign, thereby achieving the blocking and adjustment of the airflow speed of the gas flow hole 6.

[0020] The horizontal push rod 302 of this utility model is provided with a pull ring 100 at its outer end.
