Important and life-saving use
Air embolism, also known as a gas embolism, generally arises in a hospital setting. Medical practitioners can very well prevent its occurrences if they know its possible causes.
However, if not avoided, it can lead to death. The presence of one or more air bubbles in a vein or artery causes an air embolism and possibly blocks the involved blood vessel. Medically, a venous air embolism occurs when an air bubble enters a vein; an arterial air embolism results when an air bubble enters an artery.
Air could accidentally enter a patient’s blood circulation in several ways. These are surgical, pain management, diagnostic procedures, and intravenous infusion therapy. The manufacturing and healthcare market introduction of the IV infusion set with auto air stop address the prevention of air embolism caused by any form of intravenous infusion therapy. The device, for one, reduces the workload of healthcare workers. It may appear lowly and without a critical role, but it can save lives.
Parts, functions, and benefits
Auto air stop filter
The auto air stop mechanism works inside the drip chamber. The filtration membranes located at the bottom of the drip chamber and with pore diameters of 15 microns screen out particulates and prevent the entry of air into the fluid or infusion line when the intravenous bottle is empty or when the infusion liquid runs out.
In addition, the auto air stop filter maintains a constant level of fluid in the drip chamber. It prevents air bubbles from entering the patient’s venous system via the infusion line. Hence, no air can get through to the patient.
The special priming filter ensures fluid fills the infusion line (auto priming). However, the infusion line remains closed until a medical worker connects it to the patient. This safety feature helps to prevent healthcare-associated infections (HAI) by reducing the amount of liquid subject to potential bacterial colonization.
In addition, spillage of intravenous fluid over the hands, floor, and beddings does not occur. The prevention of spillage reduces the wastage of intravenous fluid and admixed medications.
Universal plastic spike with air vent and cap
The plastic spike anchors the intravenous set into the intravenous bottle. It is a universal spike that works well with all intravenous bottles. The spike has a tubular structure where the fluid passes through, and designers equipped it with a protector cap. Medical workers find it at the proximal end of the infusion set. Polyethylene makes up the protector cap that keeps the plastic spike sterile at all times. The air vent serves as the inlet of air. The air that enters through this vent helps to push the fluid downwards.
Drip chamber ring
The designers equipped the drip chamber with a ring that provides secure gripping. The ring prevents accidental dropping of the intravenous set. In addition, it helps health workers to exert more force in inserting the spike into the intravenous bottle.
Double drip chamber
The double drip chamber, made of ABS and DEHP-FREE PVC, allows easy and fast priming, providing a drop rate of 20 drops/ml. The flexible chamber allows for quick and easy compression.
DEHP free infusion lines
DEHP-FREE PVC makes up the tube, and it has a length of 150 cm. Designers made the tube transparent, so medical workers could easily see the fluid flow. It has a smooth interior wall to prevent the formation of air bubbles.
“Y” injection port
The “Y” injection port allows the administration of intermittent medications. Designers used latex-free materials to prevent the occurrences of allergies.
Roller clamp
Medical health workers find the roller clamp between the drip chamber and the infusion connector. This structure controls and regulates the liquid flow without disfiguring the intravenous tube. It provides a port to insert the spike and tube. The roller clamp slows or stops the fluid flow by compressing the tube depending on the patient’s needs. Medical workers can regulate the liquid flow from zero to the maximum allowable rate.
The Luer lock connector ensures that medical workers securely join the intravenous needle or cannula to the infusion tube, preventing leaks. The intertwining between the hub of the female fitting and the sleeve of the male fitting brings about a stable and secure connection. The stable connection prevents accidental removal of the intravenous needle.
