Abstract
An unblocking mechanism used in the thermal perfusion therapy of tumor is composed of a flexible reflux tube, a liquid medicine bag and a refluxing peristaltic pump with outlet connected to liquid medicine bag via tube and inlet connected to said flexible reflux tube with clamp-type detector. Said clamp-type detector has an internal elastic trigger to make the peristaltic pump to rotate reversely, so unblocking the reflux tube.
Description
Technical field
The present invention relates to chemotherapy of tumors equipment, the unimpeded mechanism in particularly a kind of tumor thermal perfusion therapy.
Background technology
It is the treatment means commonly used that development in recent years is got up that the circulation of tumor body cavity adds thermochemotherapy, can occur causing the return duct phenomenon of blocking because of the lump edge comes off in therapeutic process.User solves the method that blockage problem is taked at present, and the one, increase refluxing opening, adopt two to four inlets; The 2nd, increase the infusion bottle that flows backwards in addition, so that the liquid of reverse flow to be provided.These the two kinds methods that solve blockage problem are only judged by range estimation, rather than are detected automatically with anti-blocking.
Summary of the invention
Task of the present invention provides the unimpeded mechanism in a kind of tumor thermal perfusion therapy, and it has solved, and detecting circulates heats the return duct blockage problem that occurs in the chemotherapy process, and only is the problem that obstruction rather than automatic detection and unimpeded are judged in range estimation.
Technical scheme of the present invention is as follows:
Unimpeded mechanism in a kind of tumor thermal perfusion therapy, it comprises peristaltic pump, liquid storing bag and flexible pipe, described peristaltic pump is the backflow peristaltic pump, flexible pipe is the backflow flexible pipe, the port of export of backflow peristaltic pump is connected with liquid storing bag by drug liquid tube, the entrance point of backflow peristaltic pump connects the backflow flexible pipe, in the pipe side of backflow flexible pipe folder formula detector is housed, and in folder formula detector the elasticity touch device is housed;
Described elasticity touch device is equipped with an elastic rod and a microswitch, and the crooked shape rod body dividing potential drop of elastic rod is put on the tube wall of flexible pipe, and elastic rod installs around on a fulcrum and is connected to microswitch;
Backward rotation by the backflow peristaltic pump flows backwards medicinal liquid and then the realization unimpeded.
Unimpeded mechanism in the tumor thermal perfusion therapy of the present invention can detect the return duct clogging that occurs in the circulation heating chemotherapy process automatically, and get rid of automatically as a kind of blood circulation that has feedback information.Adopt detection of the present invention and unimpeded mechanism, stop up, just can get rid of automatically in case return duct takes place.
Description of drawings
Fig. 1 is the unimpeded structural scheme of mechanism in a kind of tumor thermal perfusion therapy of the present invention.
Fig. 2 is the elasticity touch device structural representation in Fig. 1 unimpeded mechanism.
The specific embodiment
Referring to Fig. 1, the present invention is the unimpeded mechanism in a kind of tumor thermal perfusion therapy, and it is equipped with backflow peristaltic pump 1, liquid storing bag 2 and backflow flexible pipe 3.The port of export of backflow peristaltic pump 1 is connected with liquid storing bag 2 by drug liquid tube 4, and the entrance point of backflow peristaltic pump 1 then connects backflow flexible pipe 3.Pacify clamped detector 5 in the pipe side of backflow flexible pipe 3, in folder formula detector 5, the elasticity touch device is installed.
Referring to Fig. 2, the elasticity touch device is equipped with an elastic rod 6 and a microswitch 7, and the crooked shape rod body dividing potential drop of elastic rod 6 is put on the tube wall of flexible pipe 3, and elastic rod 6 installs around on a fulcrum 8 and is connected to microswitch 7.When blockage phenomenon, flat depression in the tube wall meeting of flexible pipe 3, the end movement therewith of elastic rod 6 drives whole elastic rod 6 simultaneously around fulcrum 8 fine rotation, the contact of microswitch 7 is just oppressed and touched to elastic rod 6 other ends, and microswitch 7 is promptly sent signal.
In order to strengthen the elasticity of elastic rod 6, the shaft that is preferably in elastic rod 6 close fulcrum 8 places partly is connected and installed a spring 9, by the elasticity that is used for strengthening elastic rod 6 of spring 9.
Backflow peristaltic pump 1 in this mechanism flows liquid in pipe by extruding backflow flexible pipe 3, makes the chemotherapy medicinal liquid flow into liquid storing bag 2 from people's body cavity simultaneously.Elastic rod 6 in the folder formula detector 5 moves along with flexible pipe 3 caving in of tube wall, and then touches microswitch 7; Microswitch 7 is sent signal and is sent to Control Computer, because backflow peristaltic pump 1 is connected with Control Computer by circuit, Control Computer receives the signal from microswitch 7, Control Computer can be ordered 1 counter-rotating a period of time of backflow peristaltic pump, liquid instead flows thereupon in the flexible pipe 3, and its purpose is to wash open the foreign body that is blocked in 3 mouthfuls of flexible pipes.This automatically tackling blockage process system is finished by the counter-rotating of backflow peristaltic pump, and the backward rotation by the backflow peristaltic pump flows backwards medicinal liquid and then realizes unimpeded.
The time period of backflow peristaltic pump counter-rotating can be set by the people-machine dialog interface of computer within the specific limits by the user at interval.The time length of medicinal liquid refluence just can be set by people-machine dialog interface of Control Computer by the user.After the setting-up time of backflow peristaltic pump counter-rotating had arrived, Control Computer promptly ordered the backflow peristaltic pump to recover just to change, and enters normal operating conditions.
Claims (3)
