Description

Technical Field

[0001] The utility model relates to an auxiliary device for converting nasal bile duct aspiration between mouth and nose, and belongs to the technical field of medical devices. Background Art

[0002] Endoscopic retrograde cholangiopancreatography (ERCP) is an important means for treating biliary tract diseases, and endoscopic nasobiliary drainage (ENBD) is widely used for biliary decompression of patients with biliary tract diseases. In order to complete ENBD after ERCP, the drainage catheter must be repositioned from the mouth to the nostril. The existing method for exchanging the nasal bile duct between the mouth and nose is that the traction tube inserted from the nasal cavity is clamped by fingers or the nasal bile duct is exchanged by using a guide wire bent into a horseshoe shape to assist the traction tube by hand; before the repositioning of ENBD, the mouthpiece of the sedated patient must be removed from the mouth. It may take a long time for the patient to wake up. In addition, the operator's finger may be bitten due to poor cooperation of the patient. During the operation, the stimulation to the posterior pharyngeal wall is relatively large, the patient's stimulation reaction is relatively large, which is likely to induce nausea and vomiting reactions, and even damage to the pharyngeal mucosa will increase the patient's pain, and it is easy for the patient to bite the operator's hand when closing the mouth; moreover, the traction tube is usually thin and located at the back, making it difficult to observe, and the operator also needs to operate a lighting device with one hand to illuminate the patient's oral cavity, resulting in a large operation difficulty and a low success rate of converting the nasal bile duct between the mouth and nose. Aiming at the above problems, the purpose of the utility model is to provide an auxiliary device with a simple structure, convenient use and capable of accurately realizing the conversion of the nasal bile duct between the mouth and nose. Content of the Utility Model

[0004] To solve the above technical problem, the technical solution of the utility model is: an auxiliary device for converting nasal bile duct aspiration between mouth and nose, including a nasal catheter and a suction device. A magnet block is fixedly connected to the head end of the nasal catheter. The suction device includes a housing, and a retractable magnet head is arranged on the housing for attracting the magnet block.

[0005] Preferably, scale lines for indicating the length are arranged on the nasal catheter.

[0006] Preferably, the magnet block is in the shape of a cylindrical tube and is coaxial with the head end of the nasal catheter.

[0007] Preferably, a notch is arranged on the magnet head, and the width of the notch is equal to the outer diameter of the magnet block.
