Anti-backflow support for pipeline

Technical Field

The invention relates to a medical auxiliary instrument, in particular to a pipeline anti-reflux bracket.

Background

Biliary tract obstruction is a biliary tract obstruction disease caused by malignant tumors such as cholangiocarcinoma, gall bladder cancer and the like, and can cause rapid deterioration of liver function. At present, the treatment method of biliary tract obstruction mainly comprises excision operation and endoscopic treatment, and most patients choose endoscopic treatment because biliary tract obstruction is generally diagnosed at the later stage of tumor, excision difficulty is high, and excision rate is only 27%.

Along with the popularization of the endoscopic treatment, biliary stents are increasingly received by patients and family members. The existing biliary tract stent comprises a tubular stent body and a diaphragm, wherein the diaphragm is in a closed nipple shape, a closed bud shape or a horn mouth shape, and has the following defects: firstly, gaps exist among the split parts of the membrane split, the anti-reflux effect is poor, and when the pressure of the inner cavity at the downstream of the biliary tract stent is increased, liquid in the downstream pipeline is easy to reflux into the biliary tract to cause biliary tract infection and obstruction, so that complications such as jaundice, fever and abdominal pain are caused; secondly, when in diversion, the membrane flap is flushed with a through hole only by the dead weight of the liquid in the upstream bile duct, the smoothness is poor, and the diversion speed is low, so that the liquid in the upstream bile duct is gathered at the bracket, and then infection or obstruction is caused, and the illness state is aggravated. Thus, how to design an anti-reflux stent with good anti-reflux effect and good circulation is an important issue for the person skilled in the art to study.

Disclosure of Invention

The invention aims to provide a pipeline anti-reflux bracket with good anti-reflux effect and good circulation.

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

the invention relates to a pipeline anti-backflow bracket, which comprises a tubular bracket body and a diaphragm assembly arranged at one end of the bracket body, wherein the diaphragm assembly is of a horn-shaped structure, the diaphragm assembly comprises a permanent magnet valve and a milling steel valve which are hermetically connected to the bracket body through a hinge, the permanent magnet valve and the milling steel valve are of petal-shaped structures and are symmetrically arranged, a joint part of the permanent magnet valve and the milling steel valve is provided with a fixed compensation valve, and the fixed compensation valve is tightly attached to the inner surface of the permanent magnet valve and the milling steel valve; the inner surface of milling steel lamella is attached with the insulating film, the insulating film internal seal is provided with S-shaped coil, is close to the support body lateral wall internal seal that mills the steel lamella and is provided with the battery, with support body medial surface sealed interval of battery department is provided with upper contact and lower contact, the one end of S-shaped coil pass through first insulated wire with the contact electricity is connected down, its other end pass through the second insulated wire with upper contact electricity is connected, the battery is established ties on the second insulated wire.

The hinge is coated with a protective film.

The outer surface of the support body is provided with anti-skid patterns.

The outer side of the bracket body is coated with an antibiotic layer.

The invention has the advantages that when no liquid passes through, the permanent magnetic valve and the milling steel valve are magnetically attracted, so that the membrane valve assembly is in a closed state, the fixed compensation valve ensures that the membrane valve assembly is tightly closed, the liquid at the downstream of the bile duct is prevented from flowing back into the upstream of the bile duct, and the probability of infection and obstruction of patients is reduced; when there is liquid to circulate downwards in the bile duct upper reaches, when liquid submerges upper contact and lower contact, S-shaped coil circular telegram mills the steel lamella and takes magnetism, and permanent magnetism lamella and mill the steel lamella and arrange each other, and the lamella subassembly is in open condition for the liquid of bile duct upper reaches passes through the lamella subassembly fast, and the fluxion is good, effectively avoids upstream liquid to gather in lamella subassembly department, further reduces patient 'S infection and takes place the probability of obstruction, ensures patient' S safety.
