Description

Technical Field

[0001] This utility model relates to the field of respiratory stent technology, specifically a retractable and expandable respiratory stent. Background Technology

[0002] A respiratory stent is a medical device typically used to support or maintain the airway, especially in cases of airway narrowing or obstruction caused by tumors, inflammation, trauma, or other diseases. A respiratory stent can help restore or maintain normal respiratory function, prevent airway collapse, maintain airway patency, ensure smooth airflow, and help patients breathe normally. For airway narrowing caused by tumors, inflammation, infection, congenital malformations, etc., the stent can reduce airway resistance, relieve breathing difficulties caused by airway narrowing, and improve the patient's breathing quality.

[0003] When the airway is narrowed or blocked due to tumors, inflammation, trauma or other diseases, a respiratory stent can prevent airway collapse or constriction, ensure smooth airflow, and ensure that the patient can breathe normally. The airway is not fixed and its diameter and shape change during breathing due to the airflow pressure during inhalation and exhalation. When the respiratory stent does not change with the changes in the airway, it is easy for the respiratory stent to become too tight, which can cause local compression damage or ischemia in the airway, leading to further damage or discomfort. Therefore, we propose a stretchable and expandable respiratory stent. Utility Model Content

[0004] The purpose of this invention is to provide a retractable and expandable airway stent to solve the problem that when the airway stent mentioned in the background art does not change with the changes in the airway, it is easy for the airway stent to become too tight, thereby causing local pressure damage or ischemia in the airway, leading to further damage or discomfort.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a retractable and expandable respiratory tract stent, comprising a respiratory tract stent body and an antibacterial coating, wherein the antibacterial coating is provided on the outer side of the respiratory tract stent body, and an airbag layer is bonded to the inner side of the respiratory tract stent body, wherein the two sides of the airbag layer are respectively connected to airbag rings, and the two airbag rings are respectively fixed to the two sides of the respiratory tract stent body.

[0006] Preferably, the air bladder ring on the upper side of the respiratory tract stent body is connected to one end of the inflation tube, and the other end of the inflation tube is connected to the inflation pump.

[0007] Preferably, the inner side of the air sac layer is connected to the suction tube, and the outer side of the suction tube is provided with a diversion hole.

[0008] Preferably, the upper end of the diversion hole is fixed to one end of the connecting hose, and the other end of the connecting hose is connected to the ring pipe.

[0009] Preferably, the upper side of the ring tube is connected to one end of the extraction tube, and the other end of the extraction tube is connected to the suction machine.

[0011] Preferably, the connecting hose, the ring tube, and the extraction tube are made of deformable silicone material.

[0012] Compared with the prior art, the beneficial effects of this utility model are: when the main body of the retractable airway stent moves to a narrow or blocked area of ​​the airway, the inflation pump is activated, causing the main body of the airway stent to extend and fit against the inner wall of the airway under the support of the airbag layer and airbag ring. When the diameter and shape of the airway change due to airflow pressure during breathing, the inflation pump can be controlled to pump air into or out of the airbag layer and airbag ring, causing the main body of the airway stent to extend or expand in accordance with the changes in the airway, thus allowing the main body of the airway stent to extend and expand with the deformation of the airway.

[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 Figures 1-4 This utility model provides a technical solution: a retractable and expandable airway stent, comprising an airway stent body 1 and an antibacterial coating 101. The antibacterial coating 101 is provided on the outer side of the airway stent body 1, and an airbag layer 2 is bonded to the inner side of the airway stent body 1. Both sides of the airbag layer 2 are connected to airbag rings 201, and the two airbag rings 201 are fixed to both sides of the airway stent body 1. The airbag ring 201 on the upper side of the airway stent body 1 is connected to one end of an inflation tube 202, and the other end of the inflation tube 202 is connected to an inflation pump. The inner side of the airbag layer 2 is connected to a suction tube 203. The suction tube 203 is connected to a shunt hole 2031 on its outer side. The upper end of the shunt hole 2031 is fixed to one end of the connecting tube 204, and the other end of the connecting tube 204 is connected to the ring tube 205. The upper side of the ring tube 205 is connected to one end of the extraction tube 206, and the other end of the extraction tube 206 is connected to the suction machine. The airway support body 1 and the suction tube 203 are made of titanium alloy, the air bag layer 2, the air bag ring 201 and the inflation tube 202 are made of deformable silicone, and the connecting tube 204, the ring tube 205 and the extraction tube 206 are made of deformable silicone.

[0020] In specific implementation, according to Figures 1-4When the airway is narrowed or blocked due to tumors, inflammation, trauma, or other diseases, and it is necessary to insert the airway stent body 1 into the airway, a bronchoscope or endoscope is inserted through the airway stent body 1, the cuff ring 201, and the ring tube 205. Then, an air pump is used to remove air from the cuff layer 2, cuff ring 201, inflation tube 202, connecting tubing 204, ring tube 205, and extraction tube 206. The cuff layer 2, cuff ring 201, and inflation tube 202 are made of deformable silicone material, as are the connecting tubing 204, ring tube 205, and extraction tube 206. This allows the airway stent body 1 to... The airway stent body 1 is inserted into the patient's body under the guidance of a bronchoscope or endoscope. When the airway stent body 1 moves to the narrowing or obstruction of the airway, the inflation pump is activated, causing the cuff layer 2, cuff ring 201, inflation tube 202, connecting tubing 204, ring tube 205, and extraction tube 206 to refill with gas. At this time, the airway stent body 1 extends under the support of the cuff layer 2 and cuff ring 201, allowing the airway stent body 1 to adhere to the inner wall of the airway. This prevents the airway from collapsing or constricting, ensuring that the patient can breathe normally. At this time, the two cuff rings 201... Located on either side of the airway narrowing or obstruction, two airbag rings 201 assist in confining the airway stent body 1 at the narrowing or obstruction point, preventing displacement of the airway stent body 1. When the diameter and shape of the airway change due to airflow pressure during respiration, the airbag layer 2 and airbag rings 201 can be deflated or inflated by controlling the inflation pump, controlling the extension or expansion of the airway stent body 1. This allows the airway stent body 1 to adapt to changes in the airway, and the airbag rings 201 prevent displacement of the airway stent body 1 when it changes, ensuring stability. The airway stent body 1 deforms in accordance with the airway. When sputum adheres to the inner side of the airway stent body 1, the suction machine is activated, allowing the suction machine to remove the sputum through the suction tube 206 and the suction tube 203. The suction tube 203 is made of titanium alloy, which makes the suction tube 203 more structurally strong and durable, and can prevent the suction tube 203 from collapsing during suctioning. The sputum can be separated into streams through the shunt hole 2031 to prevent sputum from blocking the connecting tube 204, the ring tube 205 and the suction tube 206, so that the airway stent body 1 can stably remove sputum. Thus, the airway stent body 1 can stably remove sputum even when it expands and contracts with the deformation of the airway.

[0021] In summary, when the respiratory stent body 1 moves to a narrow or blocked area of ​​the airway, the inflation pump is activated to refill the airbag layer 2, airbag ring 201, inflation tube 202, connecting hose 204, ring tube 205, and extraction tube 206 with gas, causing the respiratory stent body 1 to adhere to the inner wall of the airway. At this time, the two airbag rings 201 are located on both sides of the narrow or blocked area of ​​the airway, preventing the respiratory stent body 1 from shifting. When the diameter and shape of the airway change due to airflow pressure during breathing, the inflation pump can be controlled to pump air out or inhale air into the airbag layer 2 and airbag ring 201, allowing the respiratory stent body 1 to change with the changes in the airway. Thus, when the respiratory stent body 1 expands and contracts with the deformation of the airway, the contents not described in detail in this description are prior art known to those skilled in the art.

[0022] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
