Auxiliary fixing device for nasobiliary tube

Technical Field

The utility model relates to the field of medical supplies, specifically a nasobiliary tube assists fixing device.

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.

After the nose bile duct is led out of the nostril, the nose bile duct needs to be properly fixed, the nose bile duct is prevented from slipping and shifting, and the pain of a patient caused by the increase of the movement of the nose bile duct is prevented. At present, no effective method for fixing the nose bile duct exists clinically, the nose bile duct is generally fixed by a medical adhesive plaster, namely, the nose bile duct is directly stuck on the skin of a patient by the adhesive plaster, and the stability of the fixing mode is insufficient, so that the nose bile duct is easy to slip from the nasal cavity.

In addition, the tube body of the nose bile duct is hard, and after the nose bile duct is led out of the nostril, the tube body is tightly attached to the inner wall of the nasal cavity or the edge of the nostril for a long time, so that pressure injury is easily caused.

Therefore, how to improve the stability of fixing the nose bile duct and avoid the nose bile duct from causing pressure sores becomes an urgent problem to be solved in the field of medical supplies.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the problem that exists among the above-mentioned background art, provide a supplementary fixing device of nose bile duct, can stably fix the nose bile duct in the nasal cavity, prevent nose bile duct slippage or aversion, can also prevent that nose bile duct from oppressing nasal cavity inner wall or nostril edge, avoid producing the pressure nature damage.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a supplementary fixing device of nose bile duct, is including the support that is arranged in inserting the nasal cavity and the support piece that is used for supporting the nose bile duct, the support surface adopts flexible close skin material, and the support middle part is equipped with the passageway that is used for the nose bile duct to pass through, support piece is arranged in the passageway and support piece is connected with the support inboard, support piece still is equipped with the fixed establishment who is used for preventing the slippage of nose bile duct.

Preferably, the support is an annular air bag, and an inflation port is arranged on the inner side of the annular air bag.

Preferably, the support member is a lantern ring with the inner diameter not smaller than the outer diameter of the nasal bile duct, the lantern ring is elastically connected with the support, and in a natural state, the axle center of the lantern ring and the axle center of the channel are located on the same straight line.

Preferably, at least three springs are arranged between the outer wall of the lantern ring and the inner side wall of the bracket, and the springs are arranged at equal intervals in the circumferential direction.

Preferably, the fixing mechanism comprises at least one main fixing band, the surface of the main fixing band is provided with a sticky surface, and one end of the main fixing band is fixedly connected with the supporting piece.

Preferably, main fixed band is equipped with at least one vice fixed band, vice fixed band surface also is equipped with the stickness face, and vice fixed band is extended to the side by main fixed band main part.

Compared with the prior art, the auxiliary fixing device for the nasobiliary tube, which adopts the technical scheme, has the following beneficial effects:

firstly, a channel for the passage of a nose bile duct is formed in the nasal cavity through an annular support, the moving range of the nose bile duct is limited in the channel inside the support, and the tube body of the nose bile duct is prevented from contacting the inner wall of the nasal cavity or the edge of the nostril, so that the pressure injury is avoided.

The main fixing belt and the auxiliary fixing belt connected with the supporting piece can be tightly attached to and wound on the nose bile duct, so that the nose bile duct is prevented from being displaced and slipping from the nasal cavity, and higher stability is achieved compared with the mode that the nose bile duct is directly fixed on skin through adhesive tapes.

Elastic connection between support piece and the support can provide certain buffering for the activity of nose bile duct in the nasal cavity, prevents that nose bile duct from oppressing the nasal cavity suddenly when receiving great external force, alleviates the painful sense of patient, improves the comfortable degree of patient.
