Right Warmth. Right Sample.
NeoWarm™ is India’s first infant heel warmer, designed to provide controlled heel warming before capillary blood collection. It helps reduce haemolysis risk, improve sample quality and lower procedural pain during heel-prick procedures.
Heats to 40.5°C

Bend. Activate. Apply.
Designed for NICU workflows
Supports routine heel-prick sampling, screening and repeated collection needs.
Controlled heel warming
Provides a standardised alternative to improvised warming methods.
For trained HCP use
Use only as per hospital protocol and approved instructions for use.
The Problem
Poor heel perfusion can compromise the sample before it reaches the lab.
Premature and low birth weight neonates can struggle to maintain peripheral temperature. Poorly perfused heels make capillary sampling difficult and may lead to squeezing or “milking” of the heel.
Excessive squeezing can dilute the specimen with tissue fluid and increase the probability of haemolysis. A rejected sample often means another prick, more delay and more nursing time.
One weak sample can create three avoidable problems.
NeoWarm™ addresses the pre-analytical step where warming and capillary flow matter.
Sample rejection
Up to 70% of rejected samples in NICUs may be due to haemolysis.*
Pseudohyperkalaemia concern
Haemolysis can elevate potassium and possible repeat testing.
Repeat heel prick
A rejected or clotted sample may lead to repeat prick, additional pain, delayed reporting and extra nursing effort.
Standardized practice
Heel warming is part of good capillary sampling technique.
-
WHO guidance notes that specimens requiring a skin puncture are best obtained after ensuring the baby is warm. CLSI GP42 provides standardised procedures for capillary blood specimen collection.

-
Supports local blood flow Heal warming can increase arterial blood flow up to 7 times and can reduce dependence on squeezing
-
Helps protect sample quality Free-flowing capillary blood collection can reduce tissue-fluid contamination and haemolysis risk.
-
Supports first-prick collection When used with correct puncture site, lancet depth and collection technique, warming can support smoother collection.
Clinical use cases
When NeoWarm™ makes the biggest difference
Three everyday NICU situations where controlled heel warming can support better collection workflow.
Routine blood sampling
Venous admixture or tissue-fluid contamination can compromise pH and gas values.
-
Controlled therapeutic warming supports superior capillary perfusion.
-
Supports more reliable pH and gas values when used with correct technique.
Prolonged NICU stay
Repeated heel pricks can compromise heel integrity over time.
-
Warming preserves heel tissue integrity and may reduce pain and crying duration.*
-
Supports a gentler sampling process in babies needing repeated tests.
Newborn screening
Slow capillary flow can lead to clotting, incomplete spots and repeated pricks.
-
Heel warming helps maintain capillary flow during collection.
-
Promotes easier collection and fewer mid-procedure interruptions.
How NeoWarm™ works
Bend. Activate. Apply.
A simple activation step makes NeoWarm™ easy to integrate into NICU blood collection protocols.
-
Bend the internal metal disc Activate the pouch by bending the disc inside the warmer.
-
Exothermic warming begins The sodium acetate system starts warming after activation.
-
Apply around the heel Wrap around the infant’s heel using the attached strip.
-
Wait 3–5 minutes, then collect Proceed with the heel-prick procedure after the recommended warming period.
-
Dispose after use NeoWarm™ is single-use. Dispose after the procedure as per hospital biomedical waste protocol.
Standardise heel warming before every indicated heel prick.
Used in NICUs across India. Review the detailed product monograph for published clinical evidence, instructions for use and approved claim references.
