Abstract

The present disclosure describes a syringe assembly including a syringe including a Luer connection and a tip, a plunger, a tip cap, a tamper evident cap disposed over the tip cap, and a film including a frangible connection. The film secures the tamper evident cap to the Luer connection, where the frangible connection can break under a force applied to the tamper evident cap such that the tamper evident cap disengages from the Luer connection when the frangible connection breaks.

Claims (41)

1. A syringe assembly, comprising:

a syringe having a barrel body that extends from a proximal end to a distal end and defines a chamber extending along an axial direction therethrough, a luer connection at the distal end, and a tip extending from the distal end along the axial direction and defining an outlet in fluid communication with the chamber, wherein the chamber contains a material;

a plunger received within the chamber of the syringe to create a fluid seal within the barrel body;

a tip cap defining a central passage configured to receive a portion of the tip such that the tip cap creates a fluid seal over the outlet;

a tamper evident assembly, comprising:

a tamper evident cap disposed over the tip cap, wherein the tamper evident cap has a main body that defines a proximal end defining an opening, a closed distal end opposite the proximal end along the axial direction, an outer surface, and an inner surface opposite the outer surface that defines a passage extending from the opening of the proximal end configured to receive the tip cap; and

a film including a frangible connection and configured to secure the tamper evident cap to the luer connection,

wherein the frangible connection is configured to break under a force applied to the tamper evident cap such that the tamper evident cap is configured to disengage from the luer connection when the frangible connection breaks.

2. The syringe assembly of claim 1 , wherein the film is shrink-wrapped over a portion of the tamper evident cap and at least a portion of the luer connection.

3. The syringe assembly of claim 1 , wherein the film includes a color-coded portion that comprises a color selected from a plurality of colors that each correspond to a different material.

4. The syringe assembly of claim 3 , wherein the color of the color-coded portion corresponds to the material in accordance with ASTM D4774.

5. The syringe assembly of claim 1 , wherein the film is adhesive-bonded to the tamper evident cap.

6. The syringe assembly of claim 1 , wherein the film is adhesive-bonded to the luer connection.

7. The syringe assembly of claim 1 , wherein the tamper evident cap includes a plurality of ribs extending radially outwards from the outer surface and configured to secure the film to the tamper evident cap.

8. The syringe assembly of claim 1 , wherein the film is configured to engage the distal end of the syringe.

9. The syringe assembly of claim 1 , wherein the luer connection includes a plurality of ribs extending outwards from an outer surface and configured to secure the film to the luer connection.

10. The syringe assembly of claim 1 , wherein a portion of the main body defines a color-coded portion that comprises a color selected from a plurality of colors that each correspond to a different material.

11. The syringe assembly of claim 1 , wherein the tamper evident cap is spaced in an entirety from the syringe when the tamper evident cap engages the tip cap.

12. The syringe assembly of claim 1 , wherein a portion of the tamper evident cap is in contact with the tip cap.

13. The syringe assembly of claim 12 , wherein the fluid seal over the outlet is not compromised when the tamper evident cap is in contact with the tip cap or when the frangible connection is broken.

14. The syringe assembly of claim 1 , wherein the material includes an active ingredient that is (a) a therapeutic agent selected from a group consisting of anti-infectives, anesthetics, analgesics, anticoagulants, chemotherapeutics, hormones, antihypertensives, anti-inflammatories, antiemetics, bronchodilators, adrenergics, immunoglobulins, antipsychotics, and antidepressants or (b) a diagnostic agent selected from a group consisting of x-ray, MRI and ultrasound contrast agents, cholecystokinetics, and vasodilators.

15. The syringe assembly of claim 1 , wherein the material includes an active ingredient selected from a group consisting of an opioid, benzodiazepine, α2-adrenergic receptor agonist, beta blocker, morphine, hydromorphone, hydrocodone, oxycodone, oxymorphone, codeine, buprenorphine, naloxone, naltrexone, fentanyl, remifentanil, sufentanil, alfentanil, meperidine, rocuronium, vecuronium, midazolam, lorazepam, diazepam, neostigmine, atropine, glycopyrrolate, dexmedetomidine, cisastracurium, ropivacaine, lidocaine, propofol, ketamine, succinylcholine, moxifloxacin, linezolid, levofloxacin, levetiracetam, vancomycin, cefepime, aztreonam, cefoxitin, ceftriaxone, cefazolin, cefotaxime, ceftazidime, gentamicin, oxacillin, nafcillin, penicillin, cefuroxime, ticarcillin, clavulanic acid, piperacillin, tazobactam, azithromycin, meropenem, ertapenem, tigecycline, micafungin, metronidazole, fluconazole, itraconazole, posaconazole, heparin, enoxaparin, dalteparin, theophylline, acetaminophen (paracetamol), ibuprofen, acetylcysteine, decitabine, azacitidine, docetaxel, pemetrexed, palonosetron, aprepitant, fosaprepitant, famotidine, amiodarone, nitroglycerin, nicardipine, clevidipine, dobutamine, esmolol, labetalol, metroprolol, somatropin, liraglutide, abaloparatide, semaglutide, teriparatide, degarelix, sumatriptan, epinephrine, ephedrine, vasopressin, methotrexate, testosterone, and hydroxyprogesterone.

16. A method of filling a syringe with a material, the method comprising:

receiving a syringe having a barrel body extending from a distal end having a luer connection and a tip, wherein the tip defines an outlet having a tip cap placed thereon, to an open proximal end, the barrel body defining a chamber that extends along an axial direction therethrough;

filling the chamber with the material through the open proximal end;

placing a plunger at the open proximal end of the chamber;

placing, after placing the plunger at the open proximal end of the chamber, a tamper evident cap over the tip cap; and

attaching a film to the tamper evident cap and the luer connection such that the film secures the tamper evident cap to the luer connection.

17. The method of claim 16 , wherein attaching the film includes shrink-wrapping the film over the tamper evident cap and the luer connection.

18. The method of claim 16 , wherein attaching the film includes attaching the film to the syringe.

19. The method of claim 16 , wherein the film includes a color-coded portion that comprises a color selected from a plurality of colors that each correspond to a different material.

20. The method of claim 19 , wherein the color of the color-coded portion corresponds to the material in accordance with ASTM D4774.

21. The method of claim 16 , further comprising:

bonding the film to the luer connection via an adhesive.

22. The method of claim 16 , further comprising:

bonding the film to the tamper evident cap via an adhesive.

23. The method of claim 16 , wherein the film includes a frangible connection configured to break under a force applied to the tamper evident cap such that the tamper evident cap is configured to disengage from the luer connection when the frangible connection breaks.

24. A tamper evident assembly, comprising:

a tamper evident cap having a main body that defines a proximal end defining an opening, a closed distal end opposite the proximal end along an axial direction, an outer surface, and an inner surface opposite the outer surface that defines a passage extending from the opening of the proximal end configured to receive a tip cap and a luer connection of a syringe; and

a film including a frangible connection and configured to secure the tamper evident cap to the luer connection, wherein the frangible connection is configured to break under a force applied to the tamper evident cap such that the tamper evident cap is configured to disengage from the luer connection when the frangible connection breaks.

25. The tamper evident assembly of claim 24 , wherein the frangible connection extends circumferentially around the tamper evident cap.
