Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, and in particular to a pressurizable ventilation T-tube. Background Technology
[0002] The T-tube used clinically is a three-channel T-shaped tubing, mainly used for conditions such as upper tracheal stenosis, tracheomalacia, and tracheal injury reconstruction. The straight tube of the T-tube is inserted into the trachea through the tracheal incision, parallel to the trachea, while the horizontal tube is exposed outside through the tracheal incision, with its opening directly connected to the outside. This achieves airway reshaping while preserving the glottic ventilation function and ensuring safe ventilation through the horizontal tube. It maintains airway patency and sufficient ventilation, exercises the respiratory function of the pharynx, and allows for the suctioning of airway secretions through the horizontal tube, preventing airway obstruction by sputum. It is an important medical device in the treatment of upper tracheal diseases and has made significant contributions to patients' well-being.
[0003] However, in actual clinical use, the above-mentioned device has the following problems: After the T-tube is inserted into the airway, if the patient's condition changes and mechanical pressure ventilation is required, it cannot be performed because the device is a three-way tube and there is a gap between it and the trachea that leaks air. Furthermore, the horizontal tube cannot be matched and connected with the auxiliary ventilation tube, so the conditions for auxiliary pressure ventilation cannot be met. The T-tube must be removed and replaced with a tracheostomy tube to perform auxiliary pressure ventilation, which increases medical procedures, medical costs and medical risks. Summary of the Invention
[0004] To address the shortcomings of the existing technology, this invention provides a pressurized ventilation T-tube, which employs an airbag installed inside the upper branch tube and outside the lower branch tube, and a connecting tube installed at the opening of the outer branch tube, enabling mechanically assisted pressurized ventilation.
[0005] The technical solution adopted by the present invention to solve the above problems is as follows: a pressurizable ventilation T-tube, comprising a T-tube, a first airbag, a first inflation tube, and a first inflation component. The T-tube is a three-way tubing composed of an upper branch tube, a lower branch tube, and an outer branch tube. The first airbag is disposed within the cavity of the upper branch tube and fixed to one inner wall. The first inflation tube passes through the walls of the upper branch tube and the outer branch tube, with one end extending out of the upper branch tube wall and communicating with the first airbag, and the other end exposed outside the outer branch tube wall and communicating with the first inflation component. The first inflatable component is a self-closing switch device, which is open when connected to the syringe and automatically closes when disconnected. The syringe is connected to the first inflatable component, and air can be injected into or deflated from the first airbag via the first inflatable tube. Inflation causes the first airbag to expand and seal the upper branch tube lumen. Continued inflation ensures a tight seal between the first airbag and the inner walls of the upper branch tube lumen. When the pressure inside the first airbag exceeds the pressure for auxiliary pressurization ventilation, leakage through the upper branch tube lumen during auxiliary pressurization ventilation is prevented. Gas is released from the first airbag, causing the first airbag to collapse and the upper branch tube lumen to open. The pressurizable ventilation T-tube also includes a second airbag, a second inflation tube, a second inflation component, and a connecting tube. The second airbag is sleeved on the outside of the lower branch tube. The second inflation tube passes through the walls of the lower branch tube and the outer branch tube, with one end extending out of the lower branch tube wall and communicating with the second airbag, and the other end exposed outside the outer branch tube wall and communicating with the second inflation component. The second inflation component is a self-closing switch device, connected to the syringe. When connected, it is in the open state; when disconnected, it automatically closes. A syringe is used to connect to the second inflator, allowing air to be inflated or deflated into the second airbag via the second inflator tube. Inflating the second airbag causes it to expand and seal the gap between the lower branch tube and the trachea, preventing air leakage during assisted pressurized ventilation. Deflating the second airbag causes it to collapse, opening the gap between the lower branch tube and the trachea, reducing the pressure of the lower branch tube on the trachea wall. One end of the connecting tube connects to the outer branch tube, and the other end can connect to the auxiliary ventilation pipe.
[0006] Compared with the prior art, the advantages of the present invention are as follows: By setting up the first airbag, the second airbag and the connecting tube, when assisted pressure ventilation is required after the airway is inserted, the first airbag and the second airbag are inflated to seal the upper branch tube lumen and the gap between the lower branch tube and the trachea, preventing air leakage during assisted pressure ventilation. Assisted pressure ventilation can be performed by connecting the mechanical assisted ventilation to the connecting tube. The gas in the airbag is withdrawn, and the three-way ventilation state is restored. This avoids the disadvantage of having to replace the tracheostomy tube to perform assisted pressure ventilation, and reduces medical operations, medical costs and medical risks.

[0008] Figure 2 is a three-dimensional structural diagram of the airbag of the present invention after inflation. Detailed Implementation
[0009] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but this is not intended to limit the present invention.
[0010] Example 1: As shown in the figure, a pressurizable ventilation T-tube includes a T-tube 1, a first airbag 5, a first inflation tube 6, and a first inflation component 7. The T-tube 1 is a three-way tube composed of an upper branch tube 2, a lower branch tube 3, and an outer branch tube 4. The first airbag 5 is disposed in the cavity of the upper branch tube 2 and fixed to one side of the inner wall. The first inflation tube 6 passes through the walls of the upper branch tube 2 and the outer branch tube 4, with one end protruding from the wall of the upper branch tube 2 and communicating with the first airbag 5, and the other end exposed on the wall of the outer branch tube 4. The first airbag 5 is connected to the first inflation component 7. A syringe connected to the first inflation component 7 can be used to inflate or deflate the first airbag 5 via the first inflation tube 6. Inflation causes the first airbag 5 to expand and seal the upper branch tube 2. Continued inflation ensures a tight seal between the first airbag 5 and the inner walls of the upper branch tube 2. When the pressure inside the first airbag 5 exceeds the pressure for auxiliary pressurization, it prevents air leakage through the upper branch tube 2 during auxiliary pressurization. Conversely, deflation causes the first airbag 5 to... The collapse opens the lumen of the upper branch pipe 2; the pressurized ventilation T-tube also includes a second airbag 8, a second inflation tube 9, a second inflation component 10, and a connecting tube 11. The second airbag 8 is sleeved on the outside of the lower branch pipe 3. The second inflation tube 9 passes through the walls of the lower branch pipe 3 and the outer branch pipe 4, with one end protruding from the wall of the lower branch pipe 3 and communicating with the second airbag 8, and the other end exposed outside the wall of the outer branch pipe 4 and communicating with the second inflation component 10. A syringe is used to connect to the second inflation component 10 and the second inflation tube 11. The trachea 9 can inflate or de-inflate the second airbag 8. Inflation causes the second airbag 8 to expand and seal the gap between the lower branch tube 3 and the trachea, preventing air leakage through the gap between the lower branch tube 3 and the trachea during assisted pressurized ventilation. Conversely, de-inflation causes the second airbag 8 to collapse, opening the gap between the lower branch tube 3 and the trachea, reducing the pressure of the lower branch tube 3 on the tracheal wall. One end of the connecting tube 11 is connected to the outer branch tube 4, and the other end can be connected to the auxiliary ventilation pipeline for assisted pressurized ventilation.
[0011] Example 2: As shown in the figure, a pressurizable ventilation T-tube is used. The other structures are the same as in Example 1. The difference is that the first inflation component 7 and the second inflation component 10 are both self-closing switch devices. When connected to the syringe, they are in the open state, and air can be inflated or deflated to the first airbag 5 and the second airbag 8 through the first inflation tube 6 and the second inflation tube 9 via the first inflation component 7 and the second inflation component 10. When disconnected from the syringe, they automatically close, which can prevent gas from entering or leaving the first airbag 5 and the second airbag 8, so as to keep the first airbag 5 and the second airbag 8 in an inflated or collapsed state.
[0012] It is worth noting that the above description is only a preferred embodiment of the present invention and does not limit the scope of patent protection of the present invention. The present invention can also improve the materials and structure of the above-mentioned components, or replace them with technical equivalents. Therefore, any equivalent structural changes made using the description and illustrations of the present invention, or direct or indirect applications to other related technical fields, are similarly included within the scope of the present invention.
