Abstract

The utility model discloses a many loops nose bile duct, including a body, body head end be the linear type, duodenum papillary part is an shape, the stomach is M shape, the nasal part is J shape, auricle portion is an shape. The multi-loop nasobiliary tube has the advantages of simple operation, firm fixation of the nasobiliary tube, difficult displacement, small damage to nasal mucosa, strong head mobility, easy replacement of fixation paste and strong observability.

Description

Multi-loop nasal bile duct

Technical Field

The utility model relates to a medical appliance, in particular to a multi-loop nasal bile duct.

Background

Endoscopic nasobiliary drainage is a clinical conventional endoscopic technique, and can be directly applied to treatment of obstructive jaundice, acute suppurative cholangitis, biliary leakage and other diseases. The postoperation indwelling nasal bile duct can fully drain bile, reduce the pressure of the biliary tract and reduce the probability of postoperation pancreatitis and cholangitis; meanwhile, the bile character and the outflow condition can be observed, and the sensitive antibiotics or hemostatics can be injected through the nasal biliary drainage tube for acute suppurative cholangitis, delayed biliary hemorrhage and the like, so the clinical effect is obvious.

The existing nose bile duct mainly comprises a straight tube or a single loop nose bile duct, and tension exists at certain positions with larger bending after the nose bile duct is implanted into a patient, so that the corresponding body part of the patient is forced or rubbed, and discomfort or complications are brought to the patient.

Disclosure of Invention

In light of the above noted deficiencies of existing nasobiliary tube designs, a multi-loop nasobiliary tube is provided.

The utility model discloses a technical means as follows: a many loops nasobiliary duct, includes the body, its characterized in that: the head end of the tube body is linear, the papillary part of duodenum is a-shaped, the stomach is M-shaped, the nose is J-shaped, and the auricle part is a-shaped.

Compared with the prior art, the utility model has the advantages of it is following:

1. the nasal tube body of the nasobiliary tube is J-shaped, so that the nasal part can be kept free of tension, compression of the tube body on nasal alar mucous membranes is avoided, and the nasal tube is better in comfort;

2. the tube body at the auricle of the nasobiliary duct is in an a shape, so that the tube body at the auricle can be kept free of tension and can be fixed on the cheek more easily;

3. the nasobiliary tube body is M-shaped, and the length of the tube body in the internal section of a patient can be changed, so that patients with different heights can keep the nasobiliary tube J-shaped tube body outside the nasal cavity.

Drawings

FIG. 1 is a schematic view of a multi-haptic nasobiliary tube.

Detailed Description

The multi-loop nasobiliary tube comprises a tube body, wherein the head end of the tube body is linear, the papillary part of duodenum is a-shaped, the stomach is M-shaped, the nose part is J-shaped, and the auricle part is a-shaped. Is prepared by molding.

The short wing of the I-shaped paster is wound at the nasobiliary tube nasolabial sulcus, and then the long wing is fixed on the nasal wing. Then the auricle part of the nose bile duct is sleeved on the auricle, the crossed part of the cheek part of the nose bile duct is wound by using a cross-shaped adhesive tape, and then the nose bile duct is fixed on the cheek. The nasal bile duct 20cm far away from the cheek is cut off, and the tail part is connected with the drainage bag through a connector; the elastic ring is wound below the joint of the drainage bag, and the nose bile duct is fixed on the clothes on the shoulder part through the pin.

The utility model can be widely popularized in the field of endoscope treatment of biliary pancreatic diseases and the like.

Claims

1. A many loops nasobiliary duct, includes the body, its characterized in that: the head end of the tube body is linear, the papillary part of duodenum is a-shaped, the stomach is M-shaped, the nose is J-shaped, and the auricle part is a-shaped.
