Semi-isolated arteriovenous pot device

Abstract

The invention discloses a semi-isolated arteriovenous pot device. The device comprises a bottle body used for loading normal saline, a semi-permeable membrane provided with a blood flow cavity and a bottle cap used for closing the bottle body, wherein an exhaust port is formed in the top of the bottle body; the bottle cap is arranged at the bottom of the bottle body; two through holes are formed in the bottom of the bottle cap; the through holes communicate with a blood inlet and a blood outlet of a circulation blood path; the semi-permeable membrane is located in the bottle body; and the cavity communicates with the through holes. According to the device, the semi-permeable membrane and the saline water which are better compatible with blood are utilized, so that contact between air and blood is effectively separated, an original air-blood contact interface is changed into an air-water-blood contact interface, the air in the blood can be exhausted more effectively, and the thrombus occurrence probability can be reduced. Therefore, the device can effectively reduce the phenomena of blood retention and blood coagulation in an arteriovenous pot.

Description

technical field [0001] The invention relates to the technical field of blood purification, more specifically, to a semi-isolated arteriovenous jug device. Background technique [0002] In the prior art, arterial jugs and venous jugs can be used to collect and separate blood 02 and air 01 during dialysis. The sources of air 01 mainly include the following three sources, one is the remaining air 01 in the circulation pipeline, the other is the air 01 infiltrated when the joints are not sealed well, and the third is the gas released from the blood 02. If these gases directly enter the human body without treatment, different clinical manifestations will occur depending on the content of air 01 in the blood vessels. If the amount of air 01 entering the blood vessel is small, the bubbles will quickly dissolve in the blood 02 and be quickly excreted through blood 02 metabolism, which will not have a serious impact on the human body. However, if more air 01 enters the blood vessel...

Problems solved by technology

[0004] However, due to the structure of the bottle body 1, the blood 02 in the upper part of the bottle body 1 cannot return to the human body in time. A ring-shaped thrombus is formed on the contact surface with the blood 02, and the ring-shaped thrombus will gradually grow up. If the patient is prone to coagulation, the thrombus will grow faster, which may block the filter screen or dialyzer, resulting in the failure of dialysis treatment. Ultimately affect the patient's treatment safety
