Since May 2021,we developed and launched the fixed-needle type LDV(LDS) syringe which reduces the amount of liquid remaining inside the syringe in order to make use of precious doses of vaccine without waste.    
When medicine is injected, a little bit of it stays behind in the syringe. It’s not much, but depending on syringe design and the cost of the drug, this waste — or dead space — can add up to as much as $2,300 per year for a patient, according to a new study from researchers at the University of North Carolina at Chapel Hill and RTI International.      
Syringe dead space is the leftover fluid that remains inside the syringe after the plunger is fully depressed. In syringes with a lot of dead space, the leftover amount averages to three percent of the volume of the medication dose. In syringes with a low-dead-space design, the volume of leftover medication averages 10 times less at 0.3 percent.    
“It is a difference of fractions of a milliliter, but when some of these medications cost more than $20,000 a month, it adds up,” said Christine Oramasionwu, lead author of the study and an assistant professor in the nation’s No. 1 ranked UNC Eshelman School of Pharmacy. “Low-dead-space design, like those with an integrated needle or a cone-shaped plunger, should be adopted as the industry standard for all syringes in order to reduce preventable and expensive medication waste.”    
So,LDS syringe is the simple and effective solution for saving your cost.
