Fiberoptic Bronchoscope Biopsy Hemostatic Balloon Sleeve

Abstract

The invention provides a device for the emergency hemostasis of acute massive hemorrhage in fiberoptic bronchoscopy, particularly a hemostatic balloon cannula for fiberoptic bronchoscopic biopsy. A polymer material is adopted to produce the device, so that the device has the characteristics of high elasticity, pressure resistance, breakage resistance and the like; structurally, the device is of a water bag structure shaped like a plurality of (two to three) strung beads, and can tightly wrap the lower end of a fiberoptic bronchoscope, the water bags are enlarged one by one, and the longitudinal section is shaped like a trapezoid. Because one section of each of water injection tubes connected with the water bags is on the operating end of the fiberoptic bronchoscope, when acute massive hemorrhage happens, normal saline can be rapidly injected by the operating end to block an organic cavity, preventing blood from further filling other bronchial trees, and thereby the hemostatic balloon cannula plays the role of emergency treatment.

Description

Technical field [0001] The invention relates to the technical field of medical treatment equipment, in particular to a hemostasis balloon sleeve for fiber bronchoscope biopsy. Background technique [0002] Bronchoscopy is a technique in which a bronchoscope with a diameter of about 0.6 cm is applied to the trachea through the mouth, nasal cavity or tracheotomy after local anesthesia is applied to the throat for examination or treatment. It is mainly suitable for the diagnosis and staging of a variety of lung diseases, especially lung cancer patients. The use of bronchoscope to make slices to obtain tissue diagnosis can make almost 50% of lung cancers diagnosed. This technology has become one of the important clinical examination items. At present, with the increase in air pollution, the prevalence of lung cancer in my country is increasing year by year, and the number of patients who need to undergo the examination is huge and increasing every year. However, this technique has ...

Problems solved by technology

[0003] Bleeding often occurs in fiberoptic bronchoscopic biopsy. Generally, negative pressure suction and local injection of hemostatic drugs can achieve hemostatic effect, but a small number of patients have a large amount of bleeding, and the above methods cannot be used to stop the bleeding. Due to the large and rapid bleeding, many patients Complete tamponade of the trachea and bronchial tree occurred within a few minutes, and the patient died of suffocation. The incidence of this complication was about 2-3 cases / 5000 people. Currently, there is no effective and rapid treatment equipment for this kind of hemorrhage

[0004] There is currently no effective hemostasis method for massive bleeding under bronchofiberoscopy. Some people try to stop the bleeding by inserting a bronchiectasis balloon through the treatment hole. However, due to the rapid bleeding, the local field of vision disappears after the bleeding, and the time it takes for the balloon to reach the bleeding site is slow, resulting in rescue failure.

In addition, when the treatment hole is acutely bleeding, blood needs to be continuously pumped. Inserting a catheter through the treatment hole obviously hinders timely and rapid rescue. Moreover, once bleeding occurs, pulling out the bronchoscope and reinserting the treatment mirror not only delays time but also whether there is blood gushing out. The field of view of the treatment mirror will disappear and endoscopy will fail; some people try to use an extra-long tracheal intubation tube to inflate and compress the main bronchus on the blocked side to stop bleeding, but it is also necessary to pull out the mirror and re-exit the endoscope, and its length is not suitable for most patients
