Description

A double-sided threaded side branch venous pot connecting tube for hemodialysis

technical field

The utility model relates to the technical field of medical devices, in particular to a double-sided threaded side branch vein pot connecting pipe for hemodialysis.

Background technique

Under normal circumstances, the blood is drawn out through the arterial line driven by the blood pump, and then returned to the body through the venous line with the venous jug after passing through the dialyzer.

During dialysis without heparin or citrate anticoagulant dialysis, the venous jug is prone to coagulation, and the venous jug cannot be returned to blood after coagulation, which directly leads to the inability to return blood to the extracorporeal circulation, resulting in blood loss. The method of replacing the pipeline during coagulation is cumbersome, time-consuming, and easy to cause blood loss. When the pipeline is disconnected, blood drips and there is a risk of infection. At present, there is no better solution for coagulation other than preventing coagulation in clinical practice.

Utility model content

In order to achieve the above purpose, the present utility model provides the following technical solutions: a double-sided threaded side branch venous pot connecting pipe for hemodialysis, comprising a first connecting pipe, a second connecting pipe, a pre-filled head and a venous pot, the first connecting pipe; One end of the connecting pipe is provided with a first connecting head, and the other end is sealed with the inlet end of the venous pot; one end of the second connecting pipe is provided with a second connecting head, and the other end is sealed with the outlet end of the venous pot; the first The connecting head and the second connecting head are both provided with the same thread, the pre-filling head is a tubular member, and the pre-filling head is connected with the first connecting head through the thread; the inlet end of the intravenous pot is provided with a dosing port, and the dosing port is on the A threaded cap with internal threads is provided.

Preferably, a filter screen is provided in the vein pot.

Preferably, the first connecting pipe and the second connecting pipe are rubber pipes.

Preferably, the dosing port and the plug are connected by threads, and the threads in the dosing port and the threads of the first connecting head cooperate with each other.

Preferably, the top end of the pre-charging head is provided with a cap, and the outer side of the pre-charging head is provided with a fixing buckle.

Compared with the prior art, the beneficial effects of the present utility model are: when the utility model is in use, one end of the interface is connected with the dialysis pipeline venous pot connector, and the other end is connected with the patient's venous needle. The blood is connected in parallel to the outside of the venous pot where coagulation is blocked, so as to replace the original venous line; it can be used after coagulation occurs to avoid waste; at the same time, the filter in the venous pot can effectively prevent thrombus from entering In the patient's body, the safety of the blood return process is guaranteed.
