Abstract
Provided is a syringe which inhibits hydrogen peroxide from decomposing. The invention is a prefilled syringe prefilled with a hydrogen peroxide solution, the prefilled syringe comprising a syringe and the hydrogen peroxide solution contained within the syringe. The hydrogen peroxide solution comprises hydrogen peroxide and water. The syringe includes a part where the syringe comes into direct contact with the hydrogen peroxide solution, the material of the syringe part being a cycloolefin polymer (COP) or a cycloolefin copolymer (COC).
Claims (16)
1. A prefilled syringe prefilled with a hydrogen peroxide solution, the prefilled syringe comprising: a syringe; and the hydrogen peroxide solution contained within the syringe, wherein a portion of the syringe which is in contact with the hydrogen peroxide solution is made of cycloolefin polymer (COP) or cycloolefin copolymer (COC), wherein the hydrogen peroxide solution comprises hydrogen peroxide and water; and wherein the contact of the hydrogen peroxide solution with the cycloolefin polymer (COP) or the cycloolefin copolymer (COC) limits decomposition of hydrogen peroxide in the hydrogen peroxide solution contained in the syringe.
2. The prefilled syringe according to claim 1, wherein the hydrogen peroxide solution further comprises an additive.
3. The prefilled syringe according to claim 1 or 2, further comprising a nozzle in a needle mounting part of the syringe.
4. The prefilled syringe according to claim 3, wherein the nozzle comprises a nozzle part and an adapter part connected to the needle mounting part of the syringe, and the nozzle part is a needle or a spray nozzle.
5. The prefilled syringe according to claim 4, wherein the needle has a groove with an echogenic pattern groove on an outer surface thereof.
6. The prefilled syringe according to claim 4 or 5, further comprising a protector, wherein the nozzle part is covered with the protector.
7. The prefilled syringe according to claim 6, wherein the protector comprises a support member, a nozzle protection part connected to one end of the support member, and an engagement part connected to the other end of the support member, and the nozzle protection part comprises a space capable of accommodating the nozzle part.
8. The prefilled syringe according to claim 7, wherein the engagement part comprises a movable part and is movably connected to the other end of the support member via the movable part.
9. The prefilled syringe according to claim 7 or 8, wherein the space is positioned on a side wall of the nozzle protection part.
10. The prefilled syringe according to claim 7, wherein the support member comprises a first arm, a second arm, a first movable part, a second movable part, and a third movable part, one end of the first arm is movably connected to the nozzle protection part via the first movable part, the other end of the first arm is movably connected to one end of the second arm via the second movable part, and one end of the second arm is movably connected to the engagement part via the third movable portion.
11. The prefilled syringe according to claim 8, wherein the movable part comprises a rail part connected to the nozzle protection part and a rail holding part connected to the engagement part, and the rail holding part holds the rail part slidably.
12. The prefilled syringe according to claim 10 or 11, wherein the space is positioned inside the nozzle protection part, and the nozzle protection part has a hollow structure.
13. The prefilled syringe according to any one of claims 1 to 12, wherein the concentration of the hydrogen peroxide in the hydrogen peroxide solution is 0.01 to 40% (w/v).
14. A kit comprising: the prefilled syringe according to claim 1, and a nozzle.
15. The kit according to claim 14, further comprising a protector for covering the nozzle part.
16. The kit according to claim 14 or 15, further comprising a syringe pump. [
