The disposable syringe with a plunger rupture device and a washer-guide sealing barrel nozzle is supposedly safe, since the plunger breaks up and the piston is stuck an the bottom of the barrel, making impossible its reloading and avoiding the use of the product. The sequence for assembling the syringe is shown on page 12/13: fitting the pressure washer to the plunger-FIG. 12.1; fitting the rubber to the piston base-FIG. 12.2; fitting the plunger to the piston-FIG. 12.3; inserting the support bolt to the fitting of the set plunger/piston-FIG. 12.4; fitting the assembled set plunger/piston into the barrel-FIG. 12.5 and finally, the screening washer is sealed, sealing the syringe entirely-FIG. 12.6. The device is totally manufactured with materials similar to the ones used in common syringes and available in the market. Syringes with this device can be assembled in syringes with volume of 0.5 cc, i.e., in all kinds of available syringes, with small changes due to their sizes, as shown on page 13/13.
