Description
Technical field
This utility model belongs to technical field of medical instruments, relates in particular to a kind of external ascites turn of tidal stream bag.
Background technology
Patients with advanced malignant tumor is often with malignant ascite, and patient, because of increased abdominal pressure, causes many symptoms, causes quality of life significantly to decline.Main Therapeutic Method has at present: diuresis method, abdominal paracentesis are put ascites and three kinds of methods of peritoneovenous shunt.The data result of diuresis ruling by law treatment malignant ascite is far from each other, the research report of Lee etc., 61% internist has applied diuretic therapy malignant ascite clinically, but only there is 45% doctor to think that it is effective, there is no at present reliable method and predict which patient will benefit from diuretic theraphy, and long-time diuresis, there will be the complication such as electrolyte disturbance.Abdominal paracentesis discharge ascites can be alleviated rapidly the symptom relevant with ascites, there will be a series of complication such as PD, Electrolyte imbalance, hypovolemia, renal function injury but put in a large number ascites.
Utility model content
Technical problem to be solved in the utility model is to provide a kind ofly can introduce intraperitoneal ascites in vein, reduce patient body adverse effect, simple structure, external ascites turn of tidal stream bag that cost is low.
In order to solve the problems of the technologies described above, the technical scheme that this utility model adopts is: a kind of external ascites turn of tidal stream bag, comprise the bag that can hold ascites, described bag one end is provided with the abdominal cavity pipe that can be connected with abdominal cavity, the other end be provided with can with the duct of Arantius of Connect of Vein, in described bag, manage with abdominal cavity the side being connected and be provided with turn of tidal stream valve, described turn of tidal stream valve is blade, described blade one end is flexibly connected with bag, and the length of blade makes can open or seal abdominal cavity pipe at the promotion lower blade of liquid.
Described duct of Arantius end-enclosed, duct of Arantius side is provided with the otch that can flow out for liquid.
Described duct of Arantius is provided with pump.
Described abdominal cavity pipe and duct of Arantius diameter are 2cm.
A technical scheme tool in technique scheme has the following advantages or beneficial effect, ascites can be introduced to vein, and minimizing is put ascites patient body is endangered, and there will not be PD, Electrolyte imbalance, hypovolemia, renal function injury; Simple structure, low price; Simple to operate, be just equivalent to venipuncture+peritoneocentesis, the doctor of all section office all can use; During if there is complication, can stop at any time turn of tidal stream; After ascites remission, can transfer at any time blood shunting device; Can repeatedly install and use, when blocking appears in turn of tidal stream valve, can change at any time.
Brief description of the drawings
The structural representation that Fig. 1 is the external ascites turn of tidal stream bag that provides in this utility model embodiment;
Labelling in above-mentioned figure is: 1, bag, 11, turn of tidal stream valve, 2, abdominal cavity pipe, 3, duct of Arantius, 31, otch, 4, pump.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, this utility model embodiment is described in further detail.
Referring to Fig. 1, a kind of external ascites turn of tidal stream bag, comprise the bag 1 that can hold ascites, bag 1 one end is provided with the abdominal cavity pipe 2 that can be connected with abdominal cavity, the other end be provided with can with the duct of Arantius of Connect of Vein 3, in bag 1, manage 2 sides that are connected with abdominal cavity and be provided with turn of tidal stream valve 11, turn of tidal stream valve 11 is blade, blade one end is flexibly connected with bag 1, and the length of blade makes can open or seal abdominal cavity pipe 2 at the promotion lower blade of liquid.Adopting in abdominal cavity pipe 2 one sides blade is set, can realize the effect of one-way flow, can only be that ascites flows into vein again from abdominal cavity pipe 2 inflow duct of Arantius 3, and the blood in vein can not reflux, and prevents backflow of blood.
Duct of Arantius 3 end-encloseds, duct of Arantius 3 sides are provided with the otch 31 that can flow out for liquid.Adopt the passage of notch-cut type, also can realize the effect of one-way flow, liquid is when managing interior outflows, and pressure struts otch 31, realizes and circulating.If adverse current, pressure, by closure of incisions 31, is realized the object of holding back, and prevents adverse current.
Duct of Arantius 3 is provided with pump 4.Pump 4 can provide power for turn of tidal stream bag, and ascites is introduced to vein.
Abdominal cavity pipe 2 and duct of Arantius 3 diameters are 2cm.Suitable puncture.
When use, by the method for puncture, vein end is inserted in superior vena cava, again abdominal end is inserted into intraperitoneal, if a large amount of ascites of intraperitoneal, intra-abdominal pressure increases, and ascites is just pushed the blade of turn of tidal stream valve 11 open, flow to superior vena cava from abdominal cavity, ascites just reduces gradually, and abdominal pressure reduces gradually, when ascites pressure ratio vein pressure low, the blade of turn of tidal stream valve, with regard to self-return, prevents backflow of blood.
Adopt after above-mentioned structure, ascites can be introduced to vein, minimizing is put ascites patient body is endangered, and there will not be PD, Electrolyte imbalance, hypovolemia, renal function injury; Simple structure, low price; Simple to operate, be just equivalent to venipuncture+peritoneocentesis, the doctor of all section office all can use; During if there is complication, can stop at any time turn of tidal stream; After ascites remission, can transfer at any time blood shunting device; Can repeatedly install and use, when blocking appears in turn of tidal stream valve, can change at any time.
By reference to the accompanying drawings this utility model is exemplarily described above; obviously this utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
