Description

Nasobiliary tube exchange assembly

Technical Field

The utility model relates to a medical instrument especially relates to nose bile duct exchange assembly.

Background

Endoscopic Nasobiliary Drainage (ENBD) is established on the basis of the diagnostic retrograde cholangiography (ERCP) technique, and is a more commonly used Endoscopic biliary Drainage method. It is inserted into bile duct via duodenal papilla under endoscope, and the other end is led out from nostril via duodenum, stomach, esophagus, pharynx, etc. to establish the extracorporeal drainage path of bile. ENBD is a simple and effective method for relieving biliary obstruction, and achieves the purposes of pressure reduction, yellow reduction and inflammation diminishing through drainage.

In the ERCP operation, the endoscope is withdrawn while the lower cannula is seen through, and the other end of the nose bile duct which is placed to the drainage position is led out from the mouth. In order to facilitate the management of the drainage tube after operation and improve the comfort of the patient, a catheter is inserted into the nose and taken out from the mouth, and the nasobiliary tube is guided out of the nostril by the guide of the catheter and is properly fixed.

In clinical operation, the sputum suction tube is frequently placed in the oral cavity through the nose, and the sputum suction tube serves as a nasal guide tube to be led out of a nasal bile duct. One end of the sputum suction tube is usually taken out of the oral cavity by two methods, namely, the sputum suction tube is taken out by a clamp under a visual laryngoscope, and the other method is that a doctor extends the oral cavity to the posterior pharyngeal cavity by fingers, grabs the front end of the sputum suction tube and pulls the front end out of the oral cavity. Both methods have operational disadvantages. The sputum suction tube is usually attached to the pharyngeal cavity of a patient close to the tracheal catheter after being placed through the nose, so that the sputum suction tube is difficult to expose, and the operation difficulty is increased. When the forceps are used, the tissue is easy to be clamped in the oral cavity to cause tissue damage, and the fingers are often used to cause the patient to feel strong nausea and vomiting and even bite the hands of the operator uncontrollably. Meanwhile, when the nose bile duct is exchanged, the nose bile duct is difficult to fix due to the thin nose bile duct, so that the nose bile duct is separated from the biliary tract.

Therefore, there is a need to design an exchanger that can be easily found and quickly removed in the mouth without damaging the tissue and causing discomfort to the patient.

The technical scheme of the utility model is that: the air bag type air-conditioning device comprises an exchange tube and an auxiliary mechanism, wherein the exchange tube comprises a hollow tube, an air bag and a one-way valve, the air bag and the one-way valve are respectively arranged at two ends of the hollow tube, an air passage is arranged on the inner wall of the hollow tube, one end port of the air passage is positioned in the air bag, the other end port of the air passage is communicated with the one-way valve, and the one-way valve is used for connecting an injector;

the auxiliary mechanism comprises a sleeve and a push-pull rod, the push-pull rod is positioned in the sleeve, two ends of the push-pull rod respectively extend out of the sleeve, one end of the push-pull rod is provided with a handle, and the other end of the push-pull rod is provided with a clamping hook.

The positioning column is arranged in the sleeve, a through hole is formed in the positioning column, and the push-pull rod is located in the through hole.

The sleeve is provided with a sliding hole, the push-pull rod is provided with a sliding rod, and the sliding rod is located in the sliding hole.

The exchange tube is made of silica gel.

The utility model discloses after ERCP operation, draw forth the postfixation with nose bile duct intranasal guiding tube (exchange tube promptly), play the effect of drainage bile. When the nose bile duct is exchanged, firstly, the air sac end of the exchange tube is placed in the oral cavity through the nose, the air is inflated into the air sac through the one-way valve, so that the air sac is inflated in the oral cavity, and the exchange tube is convenient to find and take out from the oral cavity; then the auxiliary mechanism acts to extend the sleeve and the push-pull rod into the oral cavity, the handle drives the push-pull rod to act, the hook hooks the exchange tube, the exchange tube is fixed between the hook and the sleeve, and the exchange tube is clamped and pulled out of the oral cavity; finally, the nasal bile duct penetrates into the exchange tube, and the nasal bile duct is led out from the nasal cavity after the air bag exhausts.

The utility model discloses convenient and fast operates reliably.
