Detailed Description
The present invention will be described in further detail with reference to the following examples and drawings.
Example 1
As shown in fig. 1-2, embodiment 1 of the present invention provides a nasobiliary tube with transparent scales and a flushing port, comprising a tube body 1, a flushing port 2 and a drainage bag 3 in a vacuum state before use, wherein the tube body 1 is made of transparent plastic, and the tube wall is provided with scales 11; the flushing connector 2 comprises a pipe body joint 21, a liquid injection joint 22 and a liquid outlet joint 23 which are mutually communicated, the pipe body joint 21 is connected with the pipe body 1, a water stop valve 24 is arranged on the liquid injection joint 22, the liquid outlet joint 23 is connected with a liquid inlet of the drainage bag 3, an elastic sealing plug 25 is arranged in the liquid outlet joint 23, one side of the sealing plug 25 is connected with a plug rod 26, an outlet 31 tightly attached to the plug rod 26 is arranged at the bottom of the drainage bag 3, and the end part of the plug rod 26 sequentially penetrates through the liquid outlet joint 23 and the drainage bag 3 and extends out of the outlet 31; the bottom of the drainage bag 3 is also provided with a drain valve 32.
The nasobiliary duct is used for ERCP (diagnostic retrograde cholangiography) or ENBD (endoscopic nasobiliary drainage) established on the basis thereof. When the device is used, the tube body 1 is inserted into a patient from the nose and placed correctly, the inserted position can be conveniently judged through the scales 11, then an injector for injecting contrast fluid or sterile water is connected to the liquid injection connector 22, the liquid outlet connector 23 is sealed by the sealing plug 25, the liquid injection connector 22 and the tube body connector 21 form a passage in the flushing interface 2, and the contrast fluid can be injected for radiography or the sterile water can be injected for flushing; after radiography or flushing is finished, the water stop valve 24 is closed, the plug rod 26 is pulled outwards from the bottom, the sealing plug 25 is pulled out from the liquid outlet connector 23 and enters the drainage bag 3, and due to the fact that the flushing connector 2 and the pipe body 1 are filled with liquid and the drainage bag 3 is in a vacuum state, negative pressure is generated in the liquid outlet connector 23 at the moment that the sealing plug 25 is separated from the liquid outlet connector 23, suction is generated on the liquid in the flushing connector 2, and therefore radiography liquid, sterile water or bile are sucked out of the drainage bag. When the amount of liquid is too large or a sample needs to be collected for an assay, the drain valve 32 at the bottom of the drainage bag 3 may be opened to drain the collected liquid to another container.
In a preferred mode of flushing the interface, the pipe body joint 21 and the liquid outlet joint 23 are located on the same straight line, the liquid injection joint 22 and the pipe body joint 21 and the liquid outlet joint 23 are located on the same plane, and the liquid injection joint 22 is perpendicular to the pipe body joint 21 and the liquid outlet joint 23. The design can maximize the negative pressure generated when the plug rod is drawn, thereby ensuring the smooth drainage.
The nose bile duct that this embodiment provided makes up traditional drainage tube, the three-way valve, drainage bag and be used for making the syringe of negative pressure into a whole, except annotating the liquid operation, need not carry out the operation of equipment plug repeatedly in whole drainage process, also need not additionally use the syringe to make the negative pressure, a large amount of repetitive work of dismouting equipment among the traditional operating method has been saved, and the weeping hidden danger that repeated plug equipment caused has been reduced, moreover, the steam generator is simple in structure, and convenient operation, save time, and greatly reduced the fault rate in the operation, suitable popularization and application.
Example 2
As shown in fig. 3 to 6, in the present embodiment 2, a transparent nasobiliary tube with scales and a flushing port is provided based on embodiment 1, and in the present embodiment 2, a tubular sliding bag 33 surrounding the stopper rod 26 is further disposed on an inner wall of one side of the drainage bag 3, and an inner diameter of a top opening of the sliding bag 33 is larger than an outer diameter of the stopper rod 26 and smaller than an outer diameter of the sealing plug 25; the inner side and the outer side of the sliding bag 33 are completely isolated, the bottom of the sliding bag is connected with the bottom of the drainage bag 3, and the outlet 31 is arranged at the bottom of the sliding bag 33.
