Abstract
Description
Technical Field
[0001] This utility model relates to the field of rehabilitation equipment, and in particular to a breathing exercise device for tracheotomy patients. Background Technology
[0002] With the rapid development of my country's economy and medical care, the cure rate for patients has greatly improved. However, this has been accompanied by more invasive procedures. Tracheotomy, a key treatment for patients with severe respiratory failure, neuromuscular diseases, or upper airway obstruction, effectively maintains airway patency in critical situations. However, because it bypasses the natural anatomical structure of the upper airway, patients cannot effectively clear airway secretions through physiological coughing, resulting in long-term disuse of respiratory muscles. Statistics show that over 60% of tracheotomy patients experience varying degrees of atelectasis, pulmonary infection, and diaphragmatic atrophy post-surgery, significantly prolonging hospital stays and increasing medical costs. Currently, pulmonary rehabilitation for tracheotomy patients typically utilizes respiratory training equipment (such as three-ball respirators). The training device (also known as a spirometer or spirometer) is primarily designed for patients with chronic obstructive pulmonary disease (COPD) or after thoracic surgery. Its working principle relies on training airflow resistance generated by oral occlusion. However, for tracheostomy patients, traditional devices cannot effectively generate controllable positive airway pressure due to the mismatch between the interface shape and the resistance generation mechanism. To address this, a one-way valve ventilation resistance training device has emerged on the market. Its principle is to wear a one-way valve ventilation valve on the tracheostomy cannula. During inhalation, the valve opens, and at the end of inhalation, the valve automatically closes. During exhalation, the airflow passes between the outer periphery of the tracheostomy cannula and the tracheal wall, and is expelled through the mouth and nose via the vocal cords. However, this device lacks sufficient oxygen support for tracheostomy patients, which can lead to hypoxia during training. It also cannot visually demonstrate the training effect, resulting in poor rehabilitation effects and reliability. Utility Model Content
[0003] The purpose of this invention is to provide a breathing exercise device for tracheotomy patients. This invention features an oxygen channel to prevent hypoxia, and uses a closed resistance balloon to create sufficient resistance. The expansion size further indicates the exercise effect, resulting in a device with excellent rehabilitation effects and high reliability.
[0004] The technical solution of this utility model is as follows: A breathing exercise device for tracheotomy patients includes an intubation tube, with an oxygen inlet and an air inlet respectively on both sides of the lower part of the intubation tube, an exhaust port on the upper part of the intubation tube, and a resistance balloon on the top of the intubation tube; a first one-way valve is provided on the air inlet, which conducts from the outside to the inside of the intubation tube; a second one-way valve is provided on the exhaust port, which conducts from the inside of the intubation tube to the outside; and a third one-way valve is provided in the middle of the inner cavity of the intubation tube, which conducts from the oxygen inlet and air inlet side to the resistance balloon side.
[0005] In the above-mentioned breathing exercise device for tracheostomy patients, the top of the intubation tube is provided with a threaded connecting cap, and the resistance balloon is connected to the connecting cap.
[0006] In the aforementioned breathing exercise device for tracheostomy patients, the oxygen inlet is provided with a connecting tube, which is inclined and its lower end faces the bottom of the intubation tube.
[0007] In the aforementioned breathing exercise device for tracheostomy patients, the bottom insertion end of the endotracheal tube is conical.
[0008] In the aforementioned breathing exercise device for tracheostomy patients, there are two exhaust ports, symmetrically arranged on both sides of the intubation tube.
[0009] In the aforementioned breathing exercise device for tracheotomy patients, the first one-way valve, the second one-way valve, and the third one-way valve are all composed of multiple thin-film elastic valves.
[0010] Compared with existing technologies, this invention uses a cannula fixed to the patient's tracheostomy tube opening, with the oxygen inlet connected to an oxygen source. During inhalation, the negative pressure inside the cannula causes the first one-way valve at the air inlet to open, while the third one-way valve remains closed, allowing oxygen to be inhaled from the mixed oxygen inlet, thus preventing hypoxia. During exhalation, the first one-way valve remains closed, while the third one-way valve opens. The exhaled airflow passes through the third one-way valve and enters the resistance balloon. The resistance balloon expands, generating elasticity to create resistance against the patient's exhalation, effectively exercising lung function. Furthermore, the expansion of the resistance balloon allows for external observation of the recovery process. As the pressure above the third one-way valve increases, the second one-way valve opens, gradually expelling the internal gas. Upon exhalation, the patient inhales again, the third one-way valve closes again, and the first one-way valve opens again. The elasticity of the resistance balloon restores its deformation, forcing the gas back out and further expelling it through the exhaust port via the second one-way valve for the next exhalation exercise. This invention provides an oxygen channel to prevent hypoxia, and uses a closed resistance balloon to create sufficient resistance. The expansion size further reflects the exercise effect, resulting in excellent rehabilitation effects and reliability. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.
[0016] Example 1: A breathing exercise device for tracheostomy patients, as shown in the attached document. Figure 1 and attached Figure 2 As shown, the device includes an intubation cannula 1, with oxygen inlets 2 and air inlets 3 on both sides of the lower part of the cannula 1. Two symmetrically positioned exhaust ports 4 are located on the upper part of the cannula 1. A drag balloon 5 is fixed to the top of the cannula 1. A first one-way valve 6, which connects from the outside to the inside of the cannula 1, is bonded to the air inlet 3. A second one-way valve 7, which connects from the inside to the outside of the cannula 1, is bonded to the exhaust port 4. A third one-way valve 8, which connects from the oxygen inlet 2 and air inlet 3 to the drag balloon 5, is bonded to the middle of the inner cavity of the cannula 1. The first, second, and third one-way valves are all multi-piece thin-film elastic valves arranged in a cone shape. When the cone apex acts in the opposite direction, the resistance between the valve pieces prevents deformation and keeps the valve closed. When in positive action, no compression occurs between the valve pieces, causing deformation and flipping under force, forming an opening between the valve pieces to achieve conduction. This is a technical component well-known and mastered by those skilled in the art, and will not be described in detail here. The top of the cannula 1 is threaded with a connecting cap 12, and the resistance balloon 5 is adhered to the connecting cap 12. The resistance balloon can be disassembled, and the inside of the resistance balloon and the cannula can be disinfected and cleaned. The oxygen inlet 2 has an integrally formed connecting tube 13, which is inclined and its lower end faces the bottom of the cannula 1, ensuring that the oxygen flow can be quickly directed to the patient side. The outer end of the connecting tube is connected to the oxygen source through a tubing with a Luer connector. The bottom insertion end of the cannula 1 is conical, which facilitates quick insertion into the tracheostomy cannula.
[0017] Example 2: Based on Example 1, an elastic airflow guide plate 9 with a width greater than the exhaust port 4 is bonded to the inner wall of the cannula 1 above the third one-way valve 8. The upper part of the elastic airflow guide plate 9 is bent inward and corresponds to the position of the exhaust port 4. During the blowing process, the elastic airflow guide plate is impacted and blown to cover the exhaust port 4, preventing the airflow from being directly discharged. All the gas enters the resistance balloon, causing it to expand, thereby forming greater resistance to obtain a better training effect. The elastic airflow guide plate is made of low-density, high-elasticity, and airtight material (such as medical silicone, polyurethane, etc.). Its thin sheet shape has a smaller mass and a sufficiently large area, making it easy for exhaled airflow to pass through. The lower third of the area of the balloon is bonded to the inner wall of the cannula to ensure the reliability of the connection and the force process. A guide ring 10 is bonded to the inner wall of the cannula 1 above the third one-way valve 8. The inner ring surface of the guide ring 10 is a conical surface with a bottom inner diameter larger than the top inner diameter. The inner ring of the guide ring 10 corresponds to the upper part of the elastic airflow guide plate 9. When the exhaled airflow passes through the conical surface, the cross-sectional area is reduced, which can form a larger and more concentrated airflow, and thus make it easier to push the elastic airflow guide plate. The top outer edge of the elastic airflow guide plate 9 has a guide arc surface 11, which guides the airflow expelled after the resistance balloon recovers its deformation, making it easier for it to enter the exhaust port.
[0018] Working principle: When the patient inhales, a negative pressure is formed inside the intubation tube 1. The first one-way valve 6 of the air inlet 3 opens because the external air pressure is greater than the internal air pressure. The air pressure on one side of the resistance balloon 5 is relatively high, and the third one-way valve 8 remains closed. External air enters the intubation tube 1 through the opened first one-way valve 6. At the same time, the oxygen inlet 2 is connected to the oxygen source through the connecting tube 13. Oxygen flows into the intubation tube 1 along the lower end of the inclined connecting tube 13 toward the bottom of the intubation tube 1. The two mix in the intubation tube 1 and are inhaled by the patient to avoid hypoxia. When the patient exhales, the air pressure inside the intubation tube 1 increases. The first one-way valve 6 closes because the internal air pressure is greater than the external air pressure, preventing the exhaled air from flowing back from the air inlet 3. The third one-way valve 8 opens under the push of the exhaled airflow, causing the airflow to flow towards the resistance balloon 5. After passing through the third one-way valve 8, the exhaled airflow is guided into the resistance balloon 5. As gas accumulates, the resistance balloon 5 expands, and the elasticity generated by its expansion forms resistance, resisting the patient's exhalation and exercising lung function. As the pressure above the third one-way valve 8 increases, the second one-way valve 7 opens, gradually expelling the internal gas. The degree of expansion of the resistance balloon 5 can be observed externally, visually reflecting the exercise effect; the greater the expansion, the stronger the patient's exhalation force. After exhalation, the patient inhales again, creating negative pressure inside the intubation tube 1. The third one-way valve 8 closes, preventing the gas in the resistance balloon 5 from flowing back to the middle of the intubation tube 1. The first one-way valve 6 opens again, starting a new round of inhalation. Due to its own elasticity, the resistance balloon 5 deforms and pushes the internal gas back into the intubation tube 1. The pushed-back gas enters the exhaust port 4 and is discharged outward from the intubation tube 1 through the second one-way valve 7.
