A kind of chamber system hydrops drainage systemTechnical field
This utility model relates to medical surgical instrument technical field, particularly a kind of chamber system hydrops drainage system.
Background technology
In the tumor patient postoperative reparation phase, meeting generation cavity system hydrops, usual way uses lancet puncture and connect drainage tube to flow in drainage bag, and the puncture needle used now is hard, after drain terminates, puncture needle need be pulled out, contact pin is again needed when next drain, if syringe needle is retained in patient body, because it is hard, possible patient harm.
Utility model content
This utility model provide a kind of can chamber system hydrops drainage system in indwelling patient body.
For achieving the above object, this utility model have employed following technical scheme:
Chamber system of the present utility model hydrops drainage system, comprise central venous catheter, drainage tube and drainage bag, drainage tube two ends connect central venous catheter and drainage bag respectively, central venous catheter and drainage tube are flexibly connected, the position be connected with drainage tube in central venous catheter tube wall arranges four valves, four valves form the disk of central cross opening, have circular protrusion in central venous catheter tube wall near free end.
As decision design, position, drainage tube stage casing arranges the projection of cryptomere, and form dsah-pot, dsah-pot top is provided with air inlet pipe, and plug is installed at air inlet pipe place, also comprises the flow control valve be arranged between dsah-pot and drainage bag.
Compared with prior art, the beneficial effects of the utility model are:
1) use central venous catheter to replace original hard syringe needle, by detained central venous catheter in patient body, the hydrops in drainage bag can be outwelled or change drainage bag in drainage process.
2) position be connected with drainage tube in central venous catheter, inside has four valves, and four valves form the disk of central cross opening, when drainage tube is inserted central venous catheter, push four valves open, hydrops flows in drainage bag by central venous catheter through drainage tube; Extract drainage tube after drain terminates, four valves reset and form disk, and shutoff central venous catheter, avoids hydrops to flow out, and can change drainage tube or drainage bag at this moment; Maybe can by detained central venous catheter in patient body, until hydrops reach certain capacity need drain time, insert drainage tube and drainage bag carries out drain.As the central venous catheter of Deep venou transfusion purposes as in indwelling tube indwelling patient body, each drain need not intubate again, reduces intubate number of times, reduces doctor's amount of labour, and reduce the misery of patient, reduce injury.
3) central venous catheter and drainage tube are flexibly connected, central venous catheter interface position has circular protrusion, drainage tube can be blocked, and can extract easily, the more needs of hydrops are frequently changed to the situation of drainage tube and drainage bag, this kind of structure operation is simple, convenient, reduces the workload of medical worker and family members.
4) position, drainage tube stage casing arranges the projection of cryptomere, form dsah-pot, dsah-pot top is provided with air inlet pipe, plug is installed at air inlet pipe place, before dsah-pot and drainage bag, flow control valve is installed, similar with the structure of tube for transfusion, while replacing drainage bag, can close flow control valve, and open the plug of dsah-pot top air inlet pipe, hydrops flows in dsah-pot temporary, flow control valve is opened after changing drainage bag, and block air inlet pipe with plug, hydrops is flowed in the drainage bag changed, when changing drainage bag, do not interrupt drain.

Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described in further detail.
Embodiment 1
As depicted in figs. 1 and 2, chamber system of the present utility model hydrops drainage system, comprise central venous catheter 1, drainage tube 2 and drainage bag 3, drainage tube 2 two ends connect central venous catheter 1 and drainage bag 3 respectively, central venous catheter 1 and drainage tube 2 are flexibly connected, the position be connected with drainage tube 2 in central venous catheter 1 tube wall and interface 10 place arrange the disk that four valves, 5, four valves 5 form central cross opening, have circular protrusion 6 in central venous catheter 1 tube wall near free end.
As decision design, position, drainage tube 2 stage casing arranges the projection of cryptomere, and form dsah-pot 4, dsah-pot 4 top is provided with air inlet pipe 7, and plug 8 is installed at air inlet pipe 7 place, also comprises the flow control valve 9 be arranged between dsah-pot 4 and drainage bag 3.
Use central venous catheter 1 to replace original hard syringe needle, can central venous catheter 1 is retained in patient body in drainage process, outwell the hydrops in drainage bag 3 or change drainage bag 3.
The position be connected with drainage tube 2 in central venous catheter 1, inside has the disk that four valves, 5, four valves 5 form central cross opening, when drainage tube 2 is inserted central venous catheter 1, push four valves 5 open, hydrops flows in drainage bag 3 by central venous catheter 1 through drainage tube 2; Extract drainage tube 2 after drain terminates, four sections of valves 5 reset and form disk, and shutoff central venous catheter 1, avoids hydrops to flow out, and can change drainage tube 2 or drainage bag 3 at this moment; Maybe can central venous catheter 1 be retained in patient body, until hydrops reach certain capacity need drain time, insert drainage tube 2 and drainage bag 3 carries out drain.As the central venous catheter 1 of Deep venou transfusion purposes as in indwelling tube indwelling patient body, each drain need not intubate again, reduces intubate number of times, reduces doctor's amount of labour, and reduce the misery of patient, reduce injury.
Central venous catheter 1 and drainage tube 2 are flexibly connected, central venous catheter 1 interface position has circular protrusion 6, drainage tube 2 can be blocked, and can extract easily, the more needs of hydrops are frequently changed to the situation of drainage tube 2 and drainage bag 3, this kind of structure replace tubes is simple, convenient, reduces the workload of medical worker and family members.
Position, drainage tube 2 stage casing arranges the projection of cryptomere, form dsah-pot 4, dsah-pot 4 top is provided with air inlet pipe 7, plug 8 is installed at air inlet pipe 7 place, before dsah-pot 4 and drainage bag 3, flow control valve 9 is installed, similar with the structure of tube for transfusion, while replacing drainage bag 3, can close flow control valve 9, and open the plug 8 of dsah-pot 4 top air inlet pipe 7, hydrops flows in dsah-pot 4 temporary, flow control valve 9 is opened after changing drainage bag 3, and block air inlet pipe 7 with plug 8, hydrops is flowed in the drainage bag 3 changed, when changing drainage bag 3, do not interrupt drain.
