Detailed Description

The invention will be further described with reference to the following drawings and specific embodiments:

example (b):

referring to fig. 1, the present embodiment provides a device for treating blood coagulation in a venous pot in hemodialysis, which comprises a dialysis machine body 1, a main venous pot 2 mounted on the dialysis machine body 1; the upper end and the lower end of the main venous pot 2 are respectively communicated with a blood inflow pipe 21 and a blood outflow pipe 22; the upper end of the main vein pot 2 is also communicated with an air pressure monitoring pipe 23; the filter screen 24 is arranged at the lower position in the main vein pot 2; the method is characterized in that: an overflow branch pipe 3 communicated with the interior of the main vein pot 2 is arranged on the main vein pot 2 at a position higher than the filter screen 24; the other end of the overflow branch pipe 3 is communicated to an emergency venous pot 4; the liquid outlet end of the emergency venous pot 4 is communicated with the blood outflow pipe 22 through a connecting pipe.

A first valve 31 is arranged in the overflow branch 3. The first valve 31 is arranged to prevent blood from directly flowing into the emergency venous pot 4 along the overflow branch pipe 3 when the coagulation phenomenon does not occur in the main venous pot to form a double-loop structure, so that the emergency venous pot 4 can be put into a use state at first, and the service life of the emergency venous pot is shortened.

The first valve 31 is a pressure valve, and a control branch pipe 231 is arranged on the air pressure monitoring pipe 23; and the control end of the pressure valve is controlled by the pressure in the control branch pipe 231. The pressure valve is arranged as the first valve 31, and the opening and closing of the first valve are controlled by the controlled branch pipe 231, so that the first valve 31 can be automatically controlled by the phenomenon that the pressure in the pipeline is increased when blood coagulation occurs, and the smoothness of the operation of the device is ensured; reducing the labor intensity of medical care personnel.

The overflow branch pipe 3 is a three-way pipe, and two pipelines of the three-way pipe are respectively communicated with the main venous pot 2 and the emergency venous pot 4; the third pipeline is communicated with the pre-filled normal saline bag 5, and a second valve 51 is arranged on the pipeline connected with the pre-filled normal saline bag. In a conventional hemodialysis system, a pre-flushing pipeline connected with a normal saline bag is used as an auxiliary pipeline for pre-flushing before dialysis operation, and the overflow branch pipe 3 is arranged as a three-way pipe and can be connected with the pre-flushing normal saline bag arranged on the dialysis machine body 1 so as to provide a pre-flushing effect for the main venous pot 2 and the emergency venous pot 4; the utility model provides a second valve 51 is a manual valve, can avoid being impressed the normal saline bag at the in-process blood that carries out hemodialysis through setting up this manual valve.

When the device is used for hemodialysis operation, the first valve 31 and the second valve 51 are firstly opened, the pipeline systems of the main vein pot 2 and the emergency vein pot 4 are pre-flushed by the physiological saline in the pre-flushing physiological saline bag, and the air in the pipeline systems is taken out; after the pre-flushing is finished, the first valve 31 and the second valve 51 are closed, the dialysis machine pipeline is connected to the blood pipe of the patient for dialysis operation, when the blood coagulation phenomenon occurs at the filter screen at the bottom of the main venous pot 2, the pressure in the pipeline system is increased, the first valve 31 is opened through the control branch pipe 231, so that the blood can enter the emergency venous pot 4 from the overflow branch pipe 3 at the upper part of the main venous pot 2, and the blood flows back to the body of the patient along the blood outflow pipe 22 after being filtered by the emergency venous pot 4, thereby finishing the emergency hemodialysis operation.
