Description
Technical field
This utility model relates to medical instruments field, particularly a kind of liver and gall pancreas drainage system.
Background technology
Attracting drainage technology (being called for short SD technology) is the device utilizing and having suction strength, will be free on internal a certain position
Inflammatory sepage, pus, blood or spill and leakage outer in digestive tract, there is the lead body effectively such as Digestive system destroying function of organization
Outward, cure diseases or the essential condition of complication prevention generation are created.
Basic demand to suction device should be clinically: lower negative pressure continuous and effective attracts safely.But the most clinically
Some electronic suction devices of application all also exist the practical situation attracting negative pressure the deepest.And the suction device of craft is only used for
Short time attracts and cannot be used for persistently attracting.
Summary of the invention
The purpose of this utility model is to provide a kind of liver and gall pancreas drainage system, draws meeting the surgery in curative activity
Stream demand.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model discloses a kind of liver and gall pancreas drain
Device, includes peristaltic pump and piston drainage device；Piston drainage device includes cylinder, piston, airway, liquid storage pipe, drainage tube,
Drain elastomeric bladder；Being provided with piston in cylinder, the end of piston is connected with peristaltic pump by airway, and drainage tube is y-type structure,
The end of drainage tube is connected with cylinder, and Y type end one end of drainage tube is connected with drain elastomeric bladder, and the other end is connected with liquid storage pipe.
Wherein, also including check valve, check valve is arranged on drainage tube, is positioned at Y type end and the drain elastomeric bladder of drainage tube
Between.
Wherein, liquid storage pipe top is provided with inner cap and enclosing cover, inside covers and is provided with air filter film air-vent, and air filter film is breathed freely
Aperture, hole is less than 0.22 μm；Drain elastomeric bladder is provided with conduction hole, a diameter of 3-4mm of conduction hole.
Preferably, drainage tube is degradable flexible drainage tube, and drainage tube uses polylactic acid-based degradable high polymer to prepare.
Preferably, liquid storage pipe, drainage tube, drain elastomeric bladder surface all use heparin class anticoagulant to process, and can effectively subtract
The adhesion of few internal liquid.
This utility model has the advantages that
1. this utility model is by by appropriate design, being free on the inflammatory sepage at internal a certain position, pus, blood
Or spill and leakage is outer in digestive tract, there is the lead body effectively such as Digestive system destroying function of organization outside, create cure diseases or prevention
The essential condition that complication occurs.
2. this utility model simple in construction, easy to use, easy and simple to handle, time saving and energy saving when carrying out drain to patient, carry
High drainage effect, alleviates the work difficulty of medical worker.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.
As it is shown in figure 1, the utility model discloses a kind of liver and gall pancreas drainage system, peristaltic pump 1 and piston drainage device.
Structure designs:
Piston drainage device includes cylinder 4, piston 2, airway 3, liquid storage pipe 6, drainage tube 5, drain elastomeric bladder 7；Cylinder 4
Inside being provided with piston 2, the end of piston 2 is connected with peristaltic pump 1 by airway 3, and drainage tube 5 is y-type structure, drainage tube 5
End is connected with cylinder 4, and Y type end one end of drainage tube 5 is connected with drain elastomeric bladder 7, and the other end is connected with liquid storage pipe 6, is positioned at
Being provided with check valve 12 between Y type end and the drain elastomeric bladder 7 of drainage tube 5, liquid storage pipe 6 top is provided with inner cap 10 and enclosing cover 9, interior
Being provided with air filter film air-vent 11 on lid 10, air filter film air-vent 11 aperture is less than 0.22 μm；Drain elastomeric bladder 7 is provided with
Conduction hole 8, a diameter of 3-4mm of conduction hole 8.
Operation principle:
During use, drain elastomeric bladder 7 is stretched into and need the position of drain, by operation peristaltic pump 1, gas is passed through airway
3 import in drainage tube 5, by drainage tube 5 inlet channel drain elastic bag 7, when the pressure transducer in peristaltic pump 1 senses
When pressure in drain elastic bag 7 reaches the value set, automatically switching to air-breathing mode, meanwhile, liquid passes through conduction hole 8
Enter in drainage tube 5, in the liquid storage pipe 6 of the other end then being entered Y type drainage tube 5 by check valve, this completes one
The process of secondary drain；After drain completes or liquid storage pipe 6 is filled, manually pull out drainage tube 5, change new liquid storage pipe 6, equipped with liquid
The liquid storage pipe 5 of body covers enclosing cover 9.
Wherein, liquid storage pipe 6, drainage tube 5, drain elastomeric bladder 7 surface all use heparin class anticoagulant to process, and can effectively subtract
The adhesion of few internal liquid, conveniently operates with；Drainage tube 5 uses polylactic acid-based degradable high polymer to prepare, and is to prevent
When drainage tube needs prolonged stay to be the stress avoiding producing foreign body in vivo, reduce the generation of local inflammation.
The above, only this utility model preferably detailed description of the invention, but protection domain of the present utility model is not
Being confined to this, any those familiar with the art, in the technical scope that this utility model discloses, can readily occur in
Change or replacement, all should contain within protection domain of the present utility model.
