Definitions
- This invention relates generally t9 syringes such as are used to administer medication into the body cavity (other than by oral means) via a parenteral administration unit.
- Another object is to provide an imp oved syringe that is accordingly adaptable for onetime use thereby assuring against being refilled with an inferior medication.
- Yet another object is to provide an improved syringe for one time use which accordingly would contain a unit dose quantity of medication to assure administration of a correct amount thereof.
- FIGURE 2 is a similar view shown fragmentarily, and showing the device during a plunging operation
- FIGURE 3 is a view similar to FIGURE 1 showing the plunger fully depressed and unable to be returned toward the initial position
- FIGURE 4 is a fragmentary side view of a modified form of the invention
- FIGURE 5 is a similar view thereof in an alternate position.
- the reference numeral .10 represents a disposable single unit dose syringe with locking plunger according to the present invention, wherein there is a barrel 11 and a plunger 12.
- the barrel 11 made preferably of glass comprises a cylindrical member having a constricted neck 13 and outlet opening 14 at one end thereof. At its opposite end 15, a wide opening is provided for receiving a plunger head 16.
- the cylindrical side wall 17 of the barrel encloses a central chamber 18 wherein a single dose unit of medication 19 is stored adjacent the plunger head.
- a collar 20 made of rigid material such as non-flexing plastic is rigidly affixed over the end 15 after the plunger head has been assembled into the barrel.
- the collar 20 has an inwardly extending flange 21 having a central opening 22.
- the plunger 12 comprises a stern 23 secured at one end to the plunger head, the stem extending outwardly of the barrel and having an enlarged knob 24 at its other end.
- a collar unit 25 is rigidly secured around the plunger stem, the collar unit 25 comprising a non-flexing ring 26 and a disc 27 made of flexible material such as soft rubber or flexible plastic.
- the ring 26 has a circular, outer edge 28 which is slightly less in diameter than the opening 22 so to permit movement therethrough.
- the edge 28 may be downwardly tapered inwardly so to assure against the ring becoming hung up in abutment with the collar 20.
- the disc is adjacent the outer side of the ring and has an edge 29 of diameter greater than the opening 22 whereby it must be distorted when moved therethrough.
- the plunger In operative use, to administer the medication, the plunger is moved as indicated by the arrow 30 in FIGURE 2.
- the collar unit 25 reaches the barrel collar 20
- the ring 26 passes therethrough 'without engagement therewith, but the disc being larger in diameter must be fixed as shown in the figure so as to squeeze past.
- the disc Immediately after the disc has passed therethrough it straightens to its flat original position and at the same instant the plunger has traveled its full stroke into the barrel.
- the device is removed from the patient. Should now force be accident-ally applied to pull the plunger outwardly, the disc will abut against the underside of the collar 20 preventing outward movement of the plunger. It will be noted that the ring adjacent the inner side of the disc will prevent flexing of the latter, whereas flexing was unobstructed in the opposite direction.
- FIGURES 4 and 5 a modified form 40 of the invention is shown wherein the above described barrel collar 20 and collar unit 25 are substituted by a mechanical device which comprises a pair of pawls 41 each secured pivot-ally free at one end on a pin 42 mounted in tandem relation on the stem 43.
- a notch 44 is provided on opposite sides of the stem for the purpose of receiving the pawls completely flush within the general cylindrical contour of the stem, whereby the stem may slide freely downward through an opening 45 in a rigid collar 46 wherein accordingly the opening 45 may not be distorted.
- a compression coil spring 47 extending through a transverse extending opening 48 bears at its opposite ends against the pawls and normally urges them apart. Upon downward movement of the plunger, the pawls are pivoted into the notches by force of the edge of rigid collar 46. After passing through the collar, the pawls immediately again spring into outward position to prevent upward movement of the plunger again.
- a disposable single unit dose syringe comprising a barrel containing the medication to be administered and a plunger head mounted snugly for axial movement in the barrel, said plunger head having an actuating rod of smaller diameter extending through one end of the barrel, including a locking means mounted on the rod at a predetermined fixed distance from the plunger head, in further combination with a collar mounted on the end of the "barrel encompassing the rod, said collar having a central hole through which the rod passes, said locking means coacting with said collar to permit axial movement of said plunger head to a predetermined position in said barrel, wherein the locking means comprises a relatively inflexible member of smaller dimension than the collar hole and a relatively flexible portion larger than the hole extending radially beyond the inflexible member 'whereby said member can pass through the hole with said flexible portion flexibly engaging the collar to snap behind the collar when the plunger has been moved to the determined position.
