Combined cannulation

Medifix Limited combine cannulation with blood test strips to reduce lead time in early diagnosis to prevent morbidity

Never in the history of emergency medicine has been an incidence when diagnostic tests are not performed yet no corporation or company had the idea of incorporating both together. We in Medifix are thinking ahead and working towards changing theoretical idealism into practice. When a patient is admitted to hospital in emergency situation venous access is mandatory and certain blood tests are very important to help doctors offer correct treatment. Unnecessary blood tests are often requested by doctors in an emergency situation. Blood test like Haemoglobin (anaemia), Differential white count (infections), Erythrocyte sediment rate (heart attack), Glucose (diabetic), PH (metabolic problem), Liver function test (liver failure), Urea (kidney failure, dehydration), Electrolytes (kidney, heart, dehydration), Clotting (internal bleeding, liver failure), Blood culture (Infections) are performed without any logic explanation. This results in wasted disposables devices (two syringes, one or two phlebotomy needles or butterfly and plastic connectors).

Multiple puncture sites due to phlebotomy and increase access point for skin commensal to enter resulting in infections. Various blood tests performed in emergency situation are often confusing and are repeated as soon as the patient is stable. Collect blood through the cannula is often not possible as the thin plastic tube placed in
the vein will collapse when suction is applied through the syringe. This will result in blood clots in the cannula hub and loss of venous access. Few cannula manufacturers are marketing thin plastic wires to help doctors to clear the blocked cannula.

Saline flush through the hub increase chances of introducing infections and the life of cannula would reduce due to phlebitis (infection in the vein) occurring.

Venous access is very important in managing a critically ill patient and can be very stressful if doctors lose this life line. Most experienced doctors will try to protect the venous access as it helps them to manage patient better and will anxiously wait to get the blood test results.

Cannula helps doctors initially to introduce few emergency medications, fluid or blood but at times wait for diagnostic test results before they administer medication. We feel it would benefit patients, doctors and health care providers if we could develop a method to combine venous access with early diagnostic blood test. Diagnostic blood test strips are available and are often used in emergency situation. Blood withdrawn from another
venepunctures are used but this will take away nurses time and are often not reliable as partial treatment will be commenced after introducing cannula. Test strips help diagnose blood urea, sodium, potassium, and ammonia, bilirubin, presence of drugs, acidity and bacteria are available. New test strips to check enzymes, thyroid and other hormones are undergoing trial and may replace routine blood test.

We have now successfully combined these two in our new innovation “U-Cann ST™” to help doctors and patients. U-Cann
ST™ incorporate diagnostic test strips in the blood chamber.
Blood collected in the chamber during cannulation will be absorbed by the test strip and help in early diagnosis.
Conditions like blood glucose, sodium, potassium, jaundice, dehydration, internal bleeding, metabolic or respiratory failure and cardiac arrest can be diagnosed. Presence of virus, bacteria, toxins or drugs can also be incorporated. These results will help doctors to commence treatment as soon as the cannula is placed in the blood vessels and may reduce morbidity (disability resulting after resuscitation).

Doctors and nurses are under considerable amount of pressure and usually forget to discard used needles. Needles used in syringes and phlebotomy are not protected prior use and are open to cause needle stick injuries. Four to five blood collecting bottles and arterial gas capillaries (thin glass tubes) are often used and are subjected to injuries as some tubes are made of glass.

Expensive blood analysis equipments are used in UK, USA and Europe to analyse blood in accident and emergency, operation theatre and neonatal and critical care units. These equipments are very expensive and often require maintenance. Hospitals in developing nations cannot afford to equip their department with these blood analyzers. This results in high cost of providing care in developed nations and poor quality management in developing nations. Reducing morbidity in poorer nations is very important as they do not have resources to manage disabled people. We believe in “Do No Harm”, and are constantly working towards achieving our goal.
