Safety Syringes

Unishot - Safety Syringe

Description of our product and advantages in comparison with other safety syringes

  1. it has a standard exterior appearance, the same appearance as a normal disposable syringe
  2. It is utilized as a standard disposable syringe. The only difference is the automatic needle retraction inside the plunger at the end of a normal injection by performing soft pressure on the piston.
  3. It is supplied with a double click as requested by U.S. sanitary operators. In fact, in order to retract the needle, it is necessary to perform two different clicks. With the first, the needle is hooked and the graduated barrel is completely emptied; with the second click the automatic mechanism for needle protection is activated.
  4. The automatic mechanism for needle protection is very soft and it is made by a particular tension spring inserted inside the hollow plunger. This plunger has a white colour in order to hide the mechanism that may frighten a sensitive patient. 
  5. The plunger which has a cylindrical shape is a particular characteristic that is much appreciated on the American market; the white colour helps to read through the transparent graduated scale.  
  6. It has a double safety block. After being utilized it not only insets the needle into an inaccessible position but the plunger is locked into a zero position.
  7. It is composed of only one more component (co-moulded puller spring) in comparison to a standard syringe and this component can be produced and manufactured automatically.
  8. Our experience indicates that during production it requires lower tolerances in comparison with other safety syringe products with needle protection after use.
  9. It has profitable production costs since it doesn´t require unusual and expensive components. The O-Ring gasket should have a lower cost when compared to a standard rubber gasket.
  10. Our working group doesn´t offer a new pilot plant but a plant that has already successfully produced in the past (1993); therefore we do not propose a prototype installation but a tested installation.

Why a disposable safety syringe with retractable self-locking needle?

  1. The production of disposable safety syringes with retractable self-locking needles is one of the most important realities emerging in the medical sector on a world-wide level .
  2. The social demand for disease prevention and for safety in the working environment, together with the economical necessity of reducing  various costs caused by bloodborne pathogen transmittal in hospitals, calls for the substitution of standard disposable syringes with new safety syringes
  3. The problem of accidental needlesticks alarms all government throughout the world not only because these injuries can infect the sanitary operators  with invalidating infirmities such as hepatitis B, hepatitis C, AIDS, etc., but also because the cost of treating the diseases increase the cost of National Health Insurance and  private insurances.
  4. In a joint declaration, WHO (World Health Organisation), UNICEF (United Nations Children´s Fund), UNFPA (United Nations Population Fund) and IFRC (International Federation of Red Cross and  Red Crescent Societies) entrust that all countries should use AD syringes (AD = Auto Disable - disposable syringes that cannot be utilized more than one time) to administer vaccinations and have already declared that the AD syringes exclude the risk of infection of bloodborne disease from person to person because these can not be reused.


Techno-Transfer S.r.l., in co-operation with RMB Ergon S.r.l. and with Marcolini S.n.c., intend to:


  1. offer production lines throughout the world with complete machinery set-up, training, etc., this is the clause "turn-key"
  2. trade our existing patents throughout the world together with new future patents for industrial inventions by forming agreements and granting production and commercial licenses in order to collect important cash royalties. 
  3. design even more modern sophisticated production lines for para-pharmaceutical safety products with retractable self-locking needles and will  expand this activity in the different fields of the pharmaceutical industry.
  4. register new patents for industrial inventions concerning the pharmaceutical sector in Italy and in foreign countries in order to increase sales proceeds.
  5. when required and if believed convenient, we will enter into joint-ventures with our licensees in order to prove the complete confidence we place in our patents and machinery.
