Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a blood gas measuring indwelling needle device. Background Art

[0002] In the intensive care unit, blood gas testing is a common clinical procedure.

[0003] Some high-risk patients require more frequent blood gas testing. However, frequent blood gas testing can damage the patient's blood vessels, ultimately making it impossible to collect blood gas. If blood gas is measured using an existing arterial catheter, the fluid inside the catheter can mix with the blood sample for analysis, potentially affecting the results. In actual clinical practice, some blood may be wasted, as a syringe draws blood and pushes it into a waste container. Therefore, we propose a blood gas measurement catheter device.
