Description
Technical field
A kind of medicine equipment is the utility model is related to, more particularly, to a kind of hyperthermic perfusion chemotherapy circulation line.
Background technology
Carcinous seroperitoneum is the most commonly seen adjoint disease of current late malignant tumour, and hyperthermic perfusion chemotherapy is as carcinous abdomen
The more effective a kind for the treatment of means of chamber hydrops, in wide clinical application.Thermo chemicotherapy circulation pipe line for hyperthermic perfusion chemotherapy
Be carry out hyperthermic perfusion chemotherapy must and important consumable material device, because carcinous seroperitoneum is local micro- from cancer cell destruction
Environment, the blood such as the moisture in a large amount of blood and lymph or even red blood cell and lymphocyte is caused to ooze out, diffusate is often high
It is solidifying, and contain more floccule, in hyperthermic perfusion chemotherapy, the adhesion for easily causing circulation line is blocked, and treatment can be caused to interrupt
Time is longer, influences therapeutic effect.In order to prevent blocking, people also using many methods, such as Publication No. CN1158111
Chinese patent disclose it is a kind of be used to treat the hot perfusion chemotherapeutic apparatus of intraperitoneal malignant tumour, including：Casing, reservoir are held
Device, decoction delivery pipe, heat-exchange device, attemperator, adjustable extruding charge pump.Attemperator includes exporting outside casing
The decoction exterior coating of pipe line pipe at end and the insulation water jacket positioned at two ligaments.Liquid storage container be provided with circulating medical solution reflux inlet and
Screen pack.The achievable perfusion solution closed circulation between abdominal cavity and device of the present invention, the heat lost in perfusion can be obtained constantly
It must supplement, the temperature of perfusion solution can be accurately controlled in required treatment temperature (42~43 DEG C).The technical scheme is by storing
Liquid container（That is liquid bag）The interior mode for setting screen pack reaches filter effect, to prevent from blocking.But by the equipment is used
Extrusion pump the characteristics of, the resistance of its entrance point side can not be excessive so that the mesh number of the screen pack in the technical scheme here
Can not be excessive so that its filtering is not clean, therefore, the problem of line clogging still often occurs.
The content of the invention
The utility model is mainly not thorough to circulating medical solution filtering present in solution prior art so that hot perfusionization
Treat circulation line and hold susceptible to plugging technical problem, there is provided it is a kind of simple in construction, it is easy for installation, can be to greatest extent to circulating medicine
Liquid is filtered so that perfusion chemotherapy circulation line does not allow susceptible to plugging antifouling type hyperthermic perfusion chemotherapy circulation line.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：A kind of antifouling type
Hyperthermic perfusion chemotherapy circulation line, including U-shaped heating tube, liquid bag, input pipe, output duct and extruding charge pump, its feature
It is that described extruding charge pump enters on conduit located at axle, the port of export of the extruding charge pump is provided with a filter, the filtering
Device includes a cavity, and the lower curtate of described cavity is provided with a deposit cavity, and the upside of the deposit cavity is provided with described cavity
Entrance point and the port of export separate screen pack.Extrude charge pump the port of export set filter to extruding charge pump in itself
Dynamic effect very little, so export direction of the technical program by filter located at extruding charge pump, is stayed by filter screen filtration
Under solid deposits in precipitation intracavitary so that solid matter is not left on screen pack to greatest extent, so as to will not
So that screen pack blocks.
Preferably, the inwall of described cavity is provided with annular guide plate, the annular guide plate cross section is arcuate structure,
The screen pack is provided with the mesopore of described annular guide pipe, described annular guide plate forms cavity with described screen pack
Partition.The solid matter that the technical program to leave by filter screen filtration largely can be in annular guide plate
Guide effect enters precipitation intracavitary.
Preferably, described partition is provided with upper and lower two, respectively upper partition and lower partition, wherein
The screen pack of upper partition is big mesh number screen pack, and the screen pack of lower partition is small mesh number screen pack.Big mesh number filtering
Net refers to the relatively fine screen pack of the mesh for being, small mesh number screen pack refers to the bigger screen pack of mesh, circulating medical solution elder generation
By small mesh number screen pack, first larger solid matter is filtered, allows less solid matter can be by, then by big mesh
Number screen pack is filtered, and less solid matter is filtered, this method can prevent the mutual shadow because of size material
Ring, cause the blocking of screen pack.
Preferably, the transverse width of described small mesh number screen pack is the 2/5-2/3 of big mesh number screen pack.Small mesh number mistake
For filter screen in filtering, liquid is higher by efficiency, can set bigger annular guide plate, solid matter is oriented to, and
The needs of big mesh number screen pack are a little big so that its can reach in small mesh number screen pack it is close pass through efficiency.
Preferably, the entrance point of described cavity is provided with, an inlet tube is direct, and the inlet tube is directly arranged in cavity bottom
The centre in portion, described deposit cavity are loop configuration, and its middle part is connectivity part of the inlet tube directly with cavity, the week of the connectivity part
Enclose and be provided with a ring baffle, the entirety of the ring baffle is in inverted cone-shaped structure.The structure can reduce circulation solid matter
Brought up out of deposit cavity, to improve the filter efficiency of screen pack.
The beneficial effect of the present utility model brought be solve present in prior art circulating medical solution is filtered it is not thorough
Bottom so that hyperthermic perfusion chemotherapy circulation line holds susceptible to plugging technical problem, realize it is a kind of simple in construction, it is easy for installation, can
Circulating medical solution is filtered to greatest extent so that perfusion chemotherapy circulation line does not allow the hot perfusionization of susceptible to plugging antifouling type
Treat circulation line.
