The two independent duct cavities are together connected to one end of a three-way pipe, and other two ends of the three-way pipe are opened, wherein the duct cavity for medicine is connected with a first interface after one end of the duct cavity is extended, the other duct cavity which is connected with the ball bag is connected with a second interface at the other end of the three-way pipe, and the second interface is provided with a valve.
Description
Technical field
This utility model relates to a kind ofly imports the intravital medical apparatus and instruments of people with medium, refers in particular to a kind of nose bile duct that is used for the bile duct perfusion chemotherapy.
Background technology
In recent years, the bile duct malignant tumor rises year by year at the sickness rate of China.Owing to lack the specificity clinical manifestation, early diagnostic rate is low, during most of case-finding has been middle and advanced stage, at this moment, radical-ability and even enlarge radical surgery to prolong the effect of shorter survival limited, and the excision rate has only less than 50%, for great majority forfeiture surgical engine can the patient, 1 year survival rate of postoperative still is lower than 20%, the prognosis extreme difference.For the patient of operation back and the meeting of forfeiture surgical engine, chemotherapy is the vital means that prolong its life cycle.But it is, extremely insensitive to chemotherapy because the bile duct malignant cell shows the oncobiology characteristic of the strong wellability and the high rate of transform.How strengthening chemotherapeutic efficacy clinically, is the key that improves bile duct malignant tumor patient survival rate, becomes the research focus that people pay close attention to.Though release novel chemotherapeutics clinical and experimentally continuous, or use multiple drug regimen to improve chemosensitivity, its effect is not satisfactory or still difficult to be determined.On administering mode, method through bile duct perfusion chemotherapy medicine is still a blank spot at present, on administration device, existing research and the day by day sophisticated nose bile duct that uses in ERCP (ERCP) technology are single chambeies, only play the effect of drain, can't satisfy bile duct lower end blocking effect after the perfusion of needs in perfusion chemotherapy.At Chinese patent Granted publication CN2345224Y, Granted publication day is on October 27th, 1999 " an esophageal lumen internal therapy conduit ", disclosed a kind of can be in esophageal lumen local directly apparatus of administration, its main pipe is four cavities conduit pipes, be respectively absorbing cavity, medicinal liquid splashes into chamber, preceding balloon inflation lumen and rear gasbag inflatable chamber, its shortcoming is that structure is too complicated, and operation easier is big, can not satisfy the specific (special) requirements of bile duct perfusion chemotherapy medicine simultaneously.
The utility model content
The purpose of this utility model is to provide a kind of nose bile duct that is used for the bile duct perfusion chemotherapy.
The purpose of this utility model realizes by following technical method: a kind of nose bile duct that is used for the bile duct perfusion chemotherapy, comprise a conduit, near catheter tip a α ring that prevents that conduit from skidding off from biliary tract is arranged, described catheter interior is divided into two mutual isolated independent tube chambers, one of them opening that is used for the tube chamber of dabbling drug is positioned at the side of catheter tip, the opening of another one tube chamber leaves catheter tip a segment distance, this opening part is with the conduit that a circle elastic film wraps this open section, thin film is tightened at two ends up and down, after this tube chamber injects materials such as air or normal saline, enter in the elastic film that tighten at two ends up and down from the opening outflow, form sacculus thereby expand, described two independent tube chambers insert an end of a threeway simultaneously, other two ends in this threeway separate, wherein the medicine tube chamber end that stretches out this threeway connects first interface, and the tube chamber that is provided with sacculus connects second interface at this threeway other end place.
This utility model is all right: the described catheter opening that is used for dabbling drug has 2～8, diameter is 0.8mm, be spaced apart 12mm between the opening, described sacculus is positioned at from catheter tip 7～12cm place, balloon volume is 1.0～1.5ml, and sacculus two ends up and down respectively has not saturating x light becket, is used for determining that sacculus is in the intravital position of people, distance between two saturating x light beckets is 15mm, and second of connecting of sacculus tube chamber is equipped with a valve above the interface.
Compared with prior art, the beneficial effects of the utility model are: adopt topical, overcome the shortcoming of tradition and unsatisfactory curative effect big through the peripheral vein chemical therapy toxic side effect, chemotherapy effect obviously improves, overcome simultaneously that single chamber nose bile duct only plays drainage and the shortcoming of bile duct lower end blocking effect after can not satisfying the perfusion of needs in perfusion chemotherapy, the opening part elastic film expand into sacculus under materials such as normal saline or air full, dabbling medicine can be retained in cholic lesions position a period of time, reaching therapeutic effect, and prevent that medicine from flowing into intestinal and leading to complications.
