4.THREE-WAY CONNECTOR
The connector is devised in such a way that by
turning the handle (which operates the screw) either of the 2 inlets can be connected with the
outlet whereas the remaining inlet is disconnected from the outlet. This facilitates administration of IV medications through one inlet while IV
fluids pass through the other inlet
The inlet which is connected to the outlet can
be determined by the direction of the arrows on the
handle
Uses :
o Administration of IV fluids & IV medications simultaneously by connecting the 3-way connector to the IV set.
o Exchange transfusion in case of Neonatal hyperbilirubinemia.
o Hemodialysis in case of renal failure or poisonings.
o Pleural or ascitic tap.

• Cirrhosis of Liver :
o Cryptogenic Cirrhosis Indian Childhood
Cirrhosis,Biliary Cirrhosis (Primary &Secondary)

o Malignancy :
o Leukemia,Lymphoma,Wilm’s
Tumour,Hepatoblastoma,Neuroblastoma
o Infiltration :
o Tuberculosis,Sarcoidosis ,Infections ,CMV, Herpes.
• Complications
CONTRAINDICATIONS :
• Hemorrhagic disorders
• Skin infection or recent radiation therapy at the sampling site.
• Bone disorders such as osteomyelitis or osteogenesis imperfecta.
The Three-way connector is a T-shaped device
containing 2 inlets & 1 outlet

Suction tube
Scalp Vein Needle :
41. Tony Krishnakumar
2010 MBBS Page 40
IV CANULA :
The advantages of IV canula over the scalp vein needle are :
Being plastic in nature, the IV canula does notdamage the endothelium of the vein longer- lasting than the scalp vein.
the plastic sheath being flexible can be inserted into thin & tortous veins easily (whereas the scalp vein being metallic & rigid would pierce these veins).
Tuberculin Syringe :
It is a 1 cc syringe with a white piston
Uses of the Tuberculin Syringe :
o To administer PPD for Mantoux Test.
o To administer BCG vaccine.
o To administer Test doses of drugs such as Penicillin.
o Provocative Testing — To test for allergens in Bronchial asthma, Atopy.
o Insulin injections in Diabetes Mellitus.
o Giving small doses of drugs e.g. Gentamicin, Phenobarbitone, Digoxin.
It consists of a
metallic needle attached to a
plastic tubing.
a butterfly-shaped plastic holder } At the junction of the needle & the tubing there is which facilities easy insertion of the scalp veinneedle into the vein.
o Flexible & colour-coded,
.
Uses :
Venipuncture for :
Collection of blood
Infusion of IV fluids, drugs, blood, etc.
