Abstract
Abstract A blood bag or other container which is made of a flexible, hemocompatible, sterilizable plastic material free of blood-extractable plasticizer. The blood bag contains an insert member which comprises a non-toxic, sterilizable plastic formulation which contains from 5 to 70 percent by weight of a blood-extractable plasticizer selected from the group consisting of the dioctylphthalates and dioctyladipates. Such a blood bag is capable of reducing the plasma hemoglobin in stored blood, when compared with similar blood bags without the insert member.

Claim 2
Dependent Claim
71 words
A blood bag which comprises a flexible, translucent container equipped with access tubing and sealed access ports, said blood bag comprising: a flexible, hemocompatible, sterilizable plastic material, essentially free of blood-extractable plasticizer, said blood bag containing an insert member, said insert member comprising a non-toxic, sterilizable plastic formulation which contains from 5 to 70 percent by weight of a blood-extractable plasticizer selected from the group consisting of the dioctylphthalates and dioctyladipates.
Claim 3
Dependent Claim
12 words
The blood bag of claim 1 in which said plasticizer is dioctylphthalate.
Claim 4
Dependent Claim
12 words
The blood bag of claim 1 in which said plasticizer is di-2-ethylhexylphthalate.
Claim 5
Dependent Claim
12 words
The blood bag of claim 1 in which said plasticizer is di-2-ethylhexyladipate.
Claim 6
Dependent Claim
22 words
The blood bag of claim 1 in which said insert member is from 15 to 50 percent by weight of said plasticizer.
Claim 7
Dependent Claim
15 words
The blood bag of claim 5 in which said insert member is a plastic sheet.
Claim 8
Dependent Claim
18 words
The blood bag of claim 5 in which said insert member comprises a blood-compatible plasticized polyvinyl chloride formulation.
Claim 9
Dependent Claim
75 words
A blood container which comprises a hemo-compatible, sterilizable material, essentially free of blood-extractable plasticizer, said blood container containing an insert member, said insert member comprising a non-toxic, sterilizable plastic formulation which contains sufficient material selected from the group consisting of dioctylphthalates and dioctyladipates to cause blood stored in said blood bag for 21 days to exhibit a reduced plasma hemoglobin content when compared with blood stored in a comparable blood container free of said material.
Claim 10
Dependent Claim
75 words
A blood container which comprises a hemo-compatible, sterilizable material, essentially free of blood-extractable plasticizer, said blood container containing an insert member, said insert member comprising a non-toxic, sterilizable plastic formulation which contains sufficient material selected from the group consisting of dioctylphthalates and dioctyladipates to cause blood stored in said blood bag for 21 days to exhibit a reduced plasma hemoglobin content when compared with blood stored in a comparable blood container free of said material.
Claim 11
Dependent Claim
12 words
The blood container of claim 8 in which said plasticizer is dioctylphthalate.
Claim 12
Dependent Claim
12 words
The blood container of claim 9 in which said plasticizer is di-2-ethylhexylphthalate.
Claim 13
Dependent Claim
75 words
A blood container which comprises a hemo-compatible, sterilizable material, essentially free of blood-extractable plasticizer, said blood container containing an insert member, said insert member comprising a non-toxic, sterilizable, plastic formulation which contains sufficient antihemolytic agent, capable of leaching from said plastic formulation, to cause blood stored in said blood bag for 21 days to exhibit a reduced plasma hemoglobin content when compared with blood stored in a comparable blood container free of said antihemolytic agent.
Claim 14
Dependent Claim
75 words
A blood container which comprises a hemo-compatible, sterilizable material, essentially free of blood-extractable plasticizer, said blood container containing an insert member, said insert member comprising a non-toxic, sterilizable, plastic formulation which contains sufficient antihemolytic agent, capable of leaching from said plastic formulation, to cause blood stored in said blood bag for 21 days to exhibit a reduced plasma hemoglobin content when compared with blood stored in a comparable blood container free of said antihemolytic agent.
Claim 15
Independent Claim
85 words
The method of storing blood which comprises placing said blood for a period of days into a flexible, hemocompatible, sterilizable plastic material, essentially free of blood-extractable plasticizer, said blood bag containing an insert member, said insert member comprising a non-toxic, sterilizable, plastic formulation which contains a blood extractable antihemolytic agent in sufficient quantity to cause blood stored in said blood bag for 21 days to exhibit a reduced plasma hemoglobin content when compared with blood stored in a comparable blood container free of said material.
Claim 16
Independent Claim
85 words
The method of storing blood which comprises placing said blood for a period of days into a flexible, hemocompatible, sterilizable plastic material, essentially free of blood-extractable plasticizer, said blood bag containing an insert member, said insert member comprising a non-toxic, sterilizable, plastic formulation which contains a blood extractable antihemolytic agent in sufficient quantity to cause blood stored in said blood bag for 21 days to exhibit a reduced plasma hemoglobin content when compared with blood stored in a comparable blood container free of said material.
Claim 17
