Description

TECHNICAL FIELD

[0001] The utility model belongs to air bag hemostasis mechanism technical field, especially the air bag hemostasis mechanism of catheter for airway respiratory intervention. BACKGROUND

[0002] Guide sheath (GS) as an extended working channel has been widely used in radial ultrasonic bronchoscopy and navigation bronchoscopy for diagnosing peripheral lung lesions, which simplifies the repeated positioning problem of biopsy, improves the operation efficiency and reduces the operation time. However, there is no effective compression hemostasis method when airway bleeding occurs during guide sheath airway operation, which even leads to serious complications and reduces the safety of guide sheath use.

[0003] The airway hemostasis balloon is a medical device for treating airway bleeding. In bronchoscopy operation, if the amount of lower respiratory tract bleeding reaches or exceeds 100 milliliters, it may cause serious complications such as airway obstruction. The airway hemostasis balloon can be quickly used in such cases to block bleeding and prevent rapid decrease of blood oxygen saturation. The existing airway hemostasis mechanism is an independent structure, which needs to be pre-placed in the airway during use, increasing the operation steps and affecting the work efficiency. In addition, when airway bleeding occurs during guide sheath airway operation, the pre-placed hemostasis balloon cannot guarantee 100% correct introduction to the bleeding target site, resulting in ineffective hemostasis. Therefore, the airway hemostasis mechanism for catheter for airway respiratory intervention is proposed.

[0004] The prior art document has the following problems:

[0005] The prior art document has some disadvantages when used, such as: the existing guide sheath for airway respiratory intervention does not have a hemostasis mechanism; the guide catheter with a hemostasis mechanism has a pre-confirmed size of the air bag part, which is not convenient to change the size of the air bag when used on patients, so the size of the air bag needs to be adjusted multiple times in advance according to the target bronchial diameter, which reduces the work efficiency of the guide catheter, and the existing air bag part is relatively soft, which is not convenient for insertion and guidance of the air bag part when the guide catheter is used, thereby reducing the convenience of the guide catheter when used. In view of this, we propose an air bag hemostasis mechanism for catheter for airway respiratory intervention. UTILITY MODEL CONTENTS
