Traditional hemodialysis patient blood sampling method
(1) Puncturing an arteriovenous internal fistula;
(2) connecting a 20mL syringe with an arteriovenous puncture needle, and drawing blood;
(3) opening a rubber plug of the blood sampling test tube;
(4) then injecting the blood of a 20mL syringe into the blood sampling test tube;
(5) and then plugging a rubber plug to finish the blood sampling test tube in sequence.
Traditional hemodialysis patient blood sampling method
(1) Puncturing an arteriovenous internal fistula;
(2) connecting a 20mL syringe with an arteriovenous internal fistula puncture needle for blood drawing;
(3) sleeving a 20mL syringe on a needle of a 5mL syringe;
(4) then, the blood from the 20mL syringe was sequentially injected into the blood sampling test tube.
According to the first method, the rubber plug is opened, so that the negative pressure of the blood sampling test tube disappears, the blood sample is easy to spill out in the transportation process, and the blood sample is wasted.
In the second method, the needle head is replaced, so that the blood drawing cost is increased, and the repeated needle pulling and needle inserting during the operation easily cause the puncture injury of a blood drawing person, so that the occupational risk is increased.
In addition, both methods have the risk of inaccurate extraction volumes and increased contamination of the blood sample.
In order to better solve the problems, a special hemodialysis blood collector is created.
