67 results about "Sterility assurance level" patented technology

In microbiology, sterility assurance level (SAL) is the probability that a single unit that has been subjected to sterilization nevertheless remains nonsterile. It is never possible to prove that all organisms have been destroyed, as the likelihood of survival of an individual microorganism is never zero. So SAL is used to express the probability of the survival. For example, medical device manufacturers design their sterilization processes for an extremely low SAL, such as 10⁻⁶, which is a 1 in 1,000,000 chance of a non-sterile unit. SAL also describes the killing efficacy of a sterilization process. A very effective sterilization process has a very low SAL.

Terminal sterilization of injectable collagen products

Methods of sterilizing dermal fillers and injectable collagen material have been developed which reduce the level of active biological contaminants or pathogens without adversely affecting the material, i.e., wherein the dermal fillers and injectable collagen material retain their same properties before and after its terminal sterilization. In one embodiment the method for sterilizing the dermal filler or injectable collagen material that is sensitive to radiation contains the steps of protecting the filler or material from radiation, and irradiating the filler or material with a suitable dose of radiation for a time and at a rate effective to sterilize the filler or injectable material. In a preferred embodiment the method for sterilizing the dermal filler or injectable collagen material that is sensitive to radiation includes the steps of a) freezing the filler or material at a temperature below its freezing temperature, which is generally below 0° C. and b) irradiating the filler or material with a suitable dose of radiation at an effective rate for a time effective to sterilize the filler or material. The exposure of the radiation differs depending upon the density of the filler or material, but is preferably between 5kGy and 12kGy and more preferably between 6kGy and 8kGy. These doses result in a sterility assurance level (SAL) of 10−6 SAL for the filler or material.

Netilmicin sulfate injection and preparation method thereof

The invention relates to a netilmicin sulfate injection and a preparation method thereof. The netilmicin sulfate injection is characterized in that: every 1,000 ml of injection contains 50,000,000 units of netilmicin sulfate, 0.5-2g of an antioxidant and 0.1-1g of a complexing agent, and the pH value of the netilmicin sulfate injection is 5.3-5.7. A preparation process of the netilmicin sulfate injection comprises the following steps of: cooling an appropriate amount of water for injection to below 30 DEG C under the condition that the air cleanliness is in a hundred level; introducing nitrogen to remove oxygen; adding a prescription dose of the antioxidant and the complexing agent into the water for injection for completely dissolving; adding a prescription dose of the netilmicin sulfate into a solution; stirring for completely dissolving; adsorbing with 0.05-0.2 percent (g/ml) needle active carbon; primarily filtering with one set of 1mum filter for removing carbon; adjusting the pH to 5.3-5.7 with a sodium citrate solution; stirring uniformly; fixing the volume to a full dose by using the water for injection; finely filtering with one set of 0.22/0.22mum polypropylene foldable filter core filter and two sets of 0.22/0.22mum polyether sulfone microporous membrane filter core filters for removing bacteria; embedding under a hundred-level condition (introducing nitrogen in the entire process); assisting in sterilizing at the temperature of 100 DEG C; and performing lamp inspection and packaging. Due to the adoption of a scientific formula and process, the stability of the netilmicin sulfate injection is ensured; and due to the adoption of a sterile assistant sterilization preparation method, the sterile guarantee level of a medicament is raised.

Vinpocetine injection and preparation method thereof

The invention relates to a vinpocetine injection and a production method thereof. The vinpocetine injection comprises 10 to 20 parts of vinpocetine, 0.1 to 0.45 parts of ascorbic acid, 1 to 5 parts of one or more antioxidants, 6 to 15 parts of one or more cosolvents and 2000 parts of water. The preparation method comprises the following steps of 1, filtering 80% of injection water to remove oxygen, heating to a temperature of 40 to 50 DEG C, adding ascorbic acid, the one or more cosolvents and the one or more antioxidants into the injection water, and stirring for complete dissolution, 2, adding vinpocetine into the solution obtained by the step 1, stirring for full dissolution, supplying enough injection water, and carrying out stirring adsorption by 0.3% of active carbon, and 3, carrying out disinfection at a temperature of 121 DEG C for 15 minutes, and carrying out filling under nitrogen atmosphere. The vinpocetine injection obtained by the preparation method can be subjected to sterilization at a temperature of 121 DEG C for 15 minutes. A result of detection shows that impurity content is not improved obviously and thus the vinpocetine injection is stable and can be used for industrial production. Compared with the original vinpocetine injection, the vinpocetine injection obtained by the preparation method can be subjected to overkill sterilization at a temperature of 121 DEG C for 15 minutes so that a sterility assurance level of the vinpocetine injection can be ensured.
