Description

Technical Field

[0001] The utility model relates to the technical field of venous pots, in particular to a hemodialysis machine venous pot with a pipeline separation type and not easy to coagulate blood. Background Technique

[0002] The venous pot is located in the venous pot clamp of the hemodialysis machine. There is a lot of blood in the venous pot, and there is a filtering device in the pot. When the human body undergoes hemodialysis, the blood is drawn out from the artery, flows through the venous pot through the pipeline, and after being filtered by the venous pot, the filtered blood returns to the human body through the following pipeline. However, the pipeline from the outlet of the venous pot to the back-infusion to the human body is prone to blood coagulation. The existing above-mentioned pipeline and the venous pot are integrated. If blood coagulation occurs inside the pipeline but not in the venous pot, the entire set of pipeline and venous pot need to be replaced again, which causes waste of the venous pot at this time, and the disadvantage of not being able to replace only the pipeline cannot be realized. At the same time, the filter screen in the existing venous pot is blocked by the thrombus of coagulated blood during use, affecting the reflux speed of the pipeline and the dialysis treatment of patients.

A switch valve 6 is provided on the lower connecting pipe 5; the conduit 7 is installed at one end of the lower connecting pipe 5; the connection component is used for connecting between the lower connecting pipe 5 and the conduit 7; the filtering and anti-blocking component is installed on one side of the end cover 3 and extends into the interior of the kettle body 1 to filter the thrombus that causes blood coagulation inside the kettle body.

[0020] Please refer to Figures 1-4 , the connection component shown in the figure includes an internal thread cylinder 8 fixedly sleeved on the outer side of the end of the lower connecting pipe 5. An external thread cylinder 9 is threadedly provided inside the internal thread cylinder 8. The external thread cylinder 9 is sleeved on the outer side of the conduit 7. One end of the external thread cylinder 9 is fixedly connected to one side of the screwing handle 10. The screwing handle 10 is fixedly sleeved on the outer side wall of the conduit 7.

[0021] When using the pipeline-separated, non-clotting hemodialysis machine venous kettle: first connect the end cover 3 with the kettle body 1, and when connecting, thread the internal thread 4 on the inner wall of the end cover 3 with the external thread 2 on the outer wall of the end of the kettle body 1. At this time, the filter anti-blocking component can be extended to the interior of the kettle body 1, and the filter anti-blocking component can be installed. At the same time, one end of the kettle body 1 is blocked. After the connection between the kettle body 1 and the end cover 3 is completed, the lower connecting pipe 5 and the catheter 7 are connected. When connecting, the internal thread tube 8 at the end of the lower connecting pipe 5 is threadedly connected with the external thread tube 9 on the outside of the catheter 7. At this time, the end of the catheter 7 can be inserted into the interior of the lower connecting pipe 5, and the connection between the lower connecting pipe 5 and the catheter 7 can be achieved. When the patient is using the dialysis device, if blood coagulation occurs inside the catheter 7 and the catheter 7 is blocked, the switch valve 6 on the lower connecting pipe 5 can be closed, and then the external threaded tube 9 and the internal threaded tube 8 can be disassembled to separate the catheter 7 from the lower connecting pipe 5. Then a new catheter can be taken, and the external threaded tube 9 on the outside of the new catheter can be connected to the internal threaded tube 8 on the outside of the lower connecting pipe 5. Then the catheter 7 at the end of the lower connecting pipe 5 can be replaced, and then the switch valve 6 can be opened for use. At this time, there is no need to replace or discard the kettle body 1, which can effectively reduce the waste of the kettle body 1, reduce the waste of resources, and increase the convenience of replacing the catheter 7 during use by medical staff.

[0022] Example 2

[0023] See also Figures 1-4 , this embodiment further explains Example 1, the kettle body 1, the lower pipe 5, the catheter 7, the connecting assembly and the filtering anti-blocking assembly shown in the figure, the top of the kettle body 1 is connected with an upper pipe, the side wall of the kettle body 1 at one end away from the upper pipe is provided with an external thread 2, the end of the kettle body 1 is provided with an end cover 3, and the inner wall of the end cover 3 is provided with an internal thread 4 adapted to the external thread 2; the lower pipe 5 is installed on the end cover 3 and is connected with the end cover 3, and the lower pipe 5 is provided with a switch valve 6; the catheter 7 is installed at one end of the lower pipe 5; the connecting assembly is used to connect the lower pipe 5 and the catheter 7; the filtering anti-blocking assembly is installed on one side of the end cover 3 and extends inside the kettle body 1 to filter the thrombus of blood coagulation inside the kettle body;

[0024] See also Figures 2-4 The filter anti-blocking assembly shown in the figure includes a filter screen 11 arranged on one side above the end cover 3. The filter screen 11 is funnel-shaped. One side of the filter screen 11 is connected to a collecting ball 12. The collecting ball 12 is provided with an overflow hole 13. The bottom of the collecting ball 12 is connected to a discharge pipe 14. One end of the discharge pipe 14 penetrates the end cover 3 and extends outward to be connected to a control valve 15.

[0025] See also Figure 3 and Figure 4 The side wall of the collecting ball 12 shown in the figure is fixedly connected to the inner wall of the end cover 3 through the support rod 16.

[0026] In this embodiment, a filtering and anti-blocking component is provided inside the kettle body 1, which can filter the coagulated thrombus in the blood inside the kettle body 1. After the end cap 3 is threadedly connected to the kettle body 1, the filter net 11 above the end cap 3 will be inserted into the kettle body 1 at this time and extend into the kettle body 1. The side wall of the filter net 11 contacts the inner wall of the kettle body 1, so that the blood flowing down from the back of the kettle body 1 can pass above the filter net 11. When the blood passes above the filter net 11, the coagulated blood clots will be filtered by the filter net 11 at this time. Since the filter net 11 is funnel-shaped, the filtered blood clots will fall into the collecting ball 12 with an intermediate connection at this time. The collecting ball 12 can collect the blood clots at this time. At the same time, the excess blood will overflow through the overflow holes 13 on the side wall of the collecting ball 12 and enter the kettle body 1, and flow into the lower connecting pipe 5 communicating with the end cap 3 together with the filtered blood. Then, it flows into the catheter 7 from the other end of the lower connecting pipe 5, and finally is transported to the patient's body from the other end of the catheter 7. After the collecting ball 12 collects the blood clots, the medical staff can observe the amount of blood clots inside the collecting ball 12 through the kettle body 1. If the amount of blood clots inside the collecting ball 12 reaches the connection with the filter net 11, the medical staff can open the control valve 15 on the discharge pipe 14 at this time, and then use a suction syringe to connect to one end of the discharge pipe 14 to suck out the blood clots inside the collecting ball 12, so as to realize the removal of the blood clots in the collecting ball 12, avoid excessive accumulation of blood clots inside it and cause blockage to the filtration, increase the smoothness of the blood filtration by the filter net 11, and at the same time avoid the blood clots blocking the filter net 11 and affecting the blood flow rate, thus increasing the safety of the patient's dialysis treatment.
