In order to solve the technical problem, the utility model provides a pair of prevent hemodialysis process venous catheter blocking device, including the pipe body, the one end fixedly connected with first joint of pipe body, the other end fixedly connected with second of pipe body connects, first joint and second connect all to communicate with the pipe body mutually, the inside fixedly connected with filter of pipe body.
Preferably, the outside of pipe body intercommunication has the connecting pipe, the one end fixedly connected with silica gel head of connecting pipe.
Preferably, the length of the catheter body is 10 cm.
Preferably, the diameter of the filtering hole of the filtering plate is 0.5 mm.
Preferably, the catheter body has an internal diameter of 3 mm.
Compared with the prior art, the utility model provides a pair of prevent that hemodialysis process venous catheter from blockking up device has following beneficial effect:
1. during the use, connect pipe body and dialysis tube with the second through first joint, blood will pass through the pipe body then can filter blood when blood passes through the filter like this, just so can prevent fibrin, clot and omentum majus fat entering dialysis tube, prevent that the dialysis tube from blockking up, has reached the effect of preventing the jam from this.
2. When the filter plate is used for a long time, certain blockage can be caused, at the moment, the needle head can pass through the silica gel end socket by using the injector, then the needle head enters the inside of the catheter body through the connecting pipe, then a blockage on the filter plate is sucked into the injector through the injector, then the needle head is pulled out, so that the blockage of the filter plate can be dredged, the tightness can be continuously guaranteed after the needle head is pulled out through the silica gel end socket, and the blockage dredging effect is achieved.
2. In the dialysis, this device can filter blood, even take place to block up like this, also is the preferential jam of this device, if the condition that can't dredge stifled takes place, can directly dismantle this device and change, and need not pull out the dialysis syringe needle and puncture again, has reached from this and has prevented to carry out the effect of a lot of punctures.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments; based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the first embodiment, as shown in fig. 1-4, the present invention includes a catheter body 1, a first connector 2 fixedly connected to one end of the catheter body 1, a second connector 3 fixedly connected to the other end of the catheter body 1, both the first connector 2 and the second connector 3 being connected to the catheter body 1, and a filter plate 4 fixedly connected to the interior of the catheter body 1.
Specifically, the catheter body 1 is connected with the dialysis catheter through the first connector 2 and the second connector 3, so that blood can pass through the catheter body 1 and then can be filtered when the blood passes through the filter plate 4, and the blockage of the dialysis catheter is prevented.
In the second embodiment, on the basis of the first embodiment, the outside of the catheter body 1 is communicated with a connecting pipe 5, and one end of the connecting pipe 5 is fixedly connected with a silica gel end socket 6.
Specifically, when the filter 4 live time is longer, can cause certain jam, at this moment can pass through the syringe with the syringe needle and pass silica gel head 6, then get into pipe body 1's inside through connecting pipe 5, then inhale the syringe through the plug of syringe on with filter 4, then extract the syringe needle, just so can dredge stifled to filter 4, and can continue to guarantee the leakproofness after extracting through 6 syringe needles of silica gel head.
In the third embodiment, the length of the catheter body 1 is 10cm based on the first embodiment.
In particular, the catheter body 1 is moderate in length and convenient to use.
In the fourth embodiment, the diameter of the filter holes of the filter plate 4 is 0.5mm based on the first embodiment.
