Evaluation of the functions of the temporary catheter with various tip types
Bibliographic record
Abstract
INTRODUCTION: A temporary catheter (TC) is used short-term and for emergencies. There are some cases when we cannot withdraw blood immediately after inserting the catheter in our patients. The reason is said to be the tips of the TC sticking to the vascular walls. OBJECTIVE: We evaluated examined 3 catheters with different tip shapes in a simulation circuit to assess the effect on the blood flow. METHODS: Water was circulated in the simulation circuit at 1 L/minute. Next, we inserted each TC into the model, and the TCs were connected to the dialysis circuit at 200 mL/minute. We put gold powder into the simulation circuit. We visually observed the movement of the gold power at the head of the catheter and measured the recirculation rate. RESULT: The uplift type TC was able to perform blood removal and reinfusion with the least difficulties. All recirculation rates were less than 1%. The hindrance caused by hitting a vascular wall is believed to have been reduced. CONCLUSION: With the manipulation of the catheter tip shapes, blood was able to circulate smoothly. We expect less blood clots and a decrease in sticking to the vascular wall. We plan to study these 3 catheters at clinical tests in the future.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
