Hemostatic components

Abstract

The invention relates to a hemostatic assembly. The hemostatic assembly includes a cannula assembly, a first infusion tube, a second infusion tube, a guide strip and a lantern ring. The cannula assembly comprises a support body, an inner bag and an outer bag, wherein a working channel for an endoscope to move is formed in the support body, and the inner bag and the outer bag are separately connected with the support body. The first infusion tube is communicated with the inner bag, and the second infusion tube is communicated with the outer bag. The guide strip is used for pushing the cannula assembly to move along the endoscope, and the lantern ring is used for sleeving the endoscope so that the guide strip can penetrate through the lantern ring to fit the endoscope. According to the hemostasis assembly, physiological saline can be injected into the outer bag first when massive hemorrhage happens in endoscopic diagnosis or treatment, and the endoscopic examination or treatment is continued if bleeding stops; if the outer bag is expanded through infusion but still cannot stop bleeding, the endoscope can be withdrawn from the working channel, and physiological saline is injected intothe inner bag through the first infusion tube to completely block the bronchus or the branches thereof, so that bleeding parts are limited to the lung on one side or one lung lobe, and therefore thetime for saving the life of a patient is obtained.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a hemostatic component. Background technique [0002] Bronchoscopy generally uses a bronchoscope with a diameter of about 6 mm. After local anesthesia is applied, the bronchoscope is inserted into the trachea through the oral cavity, nasal cavity or tracheotomy for inspection or treatment. With the increasing number of patients, the incidence of major bleeding related to bronchoscopic diagnosis and treatment in clinical work also increases. Among them, the acute massive hemorrhage of the lower respiratory tract with a single bleeding volume ≥ 100ml caused by bronchoscopic diagnosis and treatment operation is called "bronchoscopic diagnosis and treatment related massive bleeding", which is the most serious complication of bronchoscopic diagnosis and treatment operation, and is also the The leading cause of death in medical procedures. It occurs suddenly and can quickly...

AI Technical Summary

Problems solved by technology

However, after the balloon 12 is placed in this method, the bronchus will be completely closed, so that the bronchoscope can no longer enter the distal end of the balloon 12, and further examination, evaluation and treatment of the distal end cannot be performed.
