Abstract

The invention discloses a disposable blood collection tube for blood gas analysis. The disposable blood collection tube comprises a sample storage device, a core rod, a needle head, a hollow needle sleeve, a sealant pouring needle sleeve, and a dual-purpose cap cover, wherein an additive is arranged in the sample storage device, a needle head fixing tube is arranged at the initial end of the sample storage device, and a handle is arranged at the tail end of the sample storage device; the core rod is arranged in an inner cavity of the sample storage device, a piston is arranged at the initial end of the core rod and is sheathed into the inner cavity of the sample storage device, and a press handle is arranged at the tail end of the core rod; the hollow needle sleeve and the sealant pouring needle sleeve are sheathed onto the needle head, and an inert glue is arranged in the sealant pouring needle sleeve; the dual-purpose cap cover is sheathed onto the initial end of the sample storage device, and can also be sheathed onto the press handle; a plug is arranged at the bottom end of the inner cavity of the dual-purpose cap cover and corresponds to the end port of the needle head fixing tube. The disposable blood collection tube has the advantages that the blood collection tube is simultaneously suitable for collecting blood of arteries and veins; the cost of a patient is reduced; the sealing property is strong, and the accuracy of detection result is higher; the operability is good, and the operation time is shortened; the one-time puncturing success rate is high.

Description

technical field [0001] The invention relates to a blood collection tube for blood gas analysis. Background technique [0002] At present, only the arterial blood collection device is the only disposable special device for blood gas analysis, and other devices are required for venous blood collection. There is a lack of instruments that can be adapted to both arterial and venous blood collection. [0003] At the same time, the operation steps of arterial blood collection are: puncture blood collection after getting ready; fix the syringe after blood return, and when the blood collection volume reaches the standard, one hand pulls out the needle while the other hand holds the cotton swab to pressurize the bleeding; After the sample bubbles, immediately insert the needle into the rubber block to block and seal it; remove the needle and screw on the needle seat cap; shake the sample evenly before sending it for inspection. As an accessory of the arterial blood sampling device,...
