In hospitals, blood samples are often taken from patients through tubes (blood lines) connected to their veins. These tubes are filled with saline (salt water) to keep them clear, but before collecting blood, this saline must be flushed out. That means drawing extra blood past the sampling point—then returning it to the patient afterward. However, current systems risk introducing air into the blood line, which can be extremely dangerous—even fatal.
The
Solution
This invention is a smart syringe-like reservoir designed to collect, store, and return blood safely. Its most important feature is a special air filter that lets air out but blocks it from getting back in—especially once it comes into contact with blood. This prevents harmful air from reaching the patient. The device also minimizes empty spaces where air can hide, ensuring it’s fully cleared before blood flows in. Some versions even use springs or gas chambers to control movement smoothly and automatically.
What’s
New
The breakthrough lies in the self-sealing filter. Unlike older devices that risk air bubbles or require extra tools to block air, this system automatically seals when wet—no switches or user intervention required. The reservoir’s internal design also ensures all air is expelled before blood reaches the filter, making it safer and more foolproof.
Benefits
- Prevents deadly air bubbles from entering the patient
- Reduces blood loss by allowing drawn blood to be returned
- Easy to use and compatible with existing medical systems
- Transparent design lets staff visually confirm blood levels
- Single-turn or pull-push operation for quick, hygienic use
