Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
Introduction
At present, most of the domestic disposable infusion and blood transfusion device components use cyclohexanone-based adhesives, and cyclohexanone is used in the formulation. the Lord. Some enterprises directly draw cyclohexanone when they are bonded, and there will be an excess of cyclohexanone in the operation, so that a large number of rings remain in the tube wall and the inner cavity. Hexanone.
The data indicate that cyclohexanone has a central nervous system inhibitory effect and a high concentration of cyclohexanone has an anesthetic effect. Cyclohexanone vapor on mucous membrane It has a strong stimulating effect, and long-term skin contact with cyclohexanone liquid can cause skin irritation and severe conjunctival irritation.
At present, the national standards and industry standards for infusion and blood transfusion devices in China do not specify the limit requirements for cyclohexanone adhesives.
A variety of analytical methods can be used to determine the amount of cyclohexanone dissolved, typical methods include gas chromatography (GC), gas chromatography/mass spectrometry Usage (GC/MS), etc. This standard uses top air phase chromatography as the basic method and gives the test procedure.
Although the type of adhesive used in infusion and blood transfusion apparatus is not limited to cyclohexanone, this standard only gives a method for measuring the amount of cyclohexanone dissolved. another In addition, the clinical application of the device varies greatly. In some cases, the published literature methods include the methods given in this standard.
Not necessarily for all instruments. Therefore, any method that demonstrates reliable analysis can be used. "Reliable analysis" means that the device is specific When the extraction liquid obtained under the leaching medium and the conditions is analyzed for the amount of cyclohexanone eluted, the selected method has sufficient precision, accuracy, and Linearity, sensitivity and selectivity.
1 Scope
This standard specifies the method for determining the amount of cyclohexanone dissolved in infusion and blood transfusion equipment.
This standard applies to infusion and blood transfusion devices using cyclohexanone as a binder.
2 Normative references
The following documents are indispensable for the application of this document. For dated references, only dated versions apply to this document. For undated references, the latest edition (including all amendments) applies to this document.
GB/T 6682 Analytical laboratory water specifications and test methods
3 General
3.1 The room temperature in this standard, if not specified, should be 10 ° C ~ 30 ° C.
3.2 The test water in this standard shall meet the requirements of GB/T 6682.
3.3 Containers used in this standard shall be borosilicate glass containers unless otherwise specified.
3.4 The precision measurement referred to in this standard shall be taken by pipettes that meet the accuracy requirements of the corresponding national standards.
4 Preparation of extract
4.1 General
For the preparation of extracts of cyclohexanone dissolved in medical devices using cyclohexanone as a binder, consideration should be given to the clinical use of the medical device.
The use conditions in the selection of suitable extraction liquid preparation methods, such as extraction solvent, time, temperature and mode of action.
It is advisable to demonstrate the preparation method of the extract to prove that the extraction conditions selected for the instrument represent the most important product brought to the patient in the intended use. Big risk.
4.2 Screening and leaching
The sample was cut into 1 cm long sections, added to a glass container, water was added in a ratio of 0.2 g/mL, and sealed at 150 ° C/min at 37 ° C.
Shake for 24 h, then take a part of the extract as a test solution.
Note. If the screening test results exceed the maximum allowable dose of the human body, consider using the simulated extraction (4.3) to prepare the extract for further testing.
1) or other methodologically validated alternative fluids, such as the alternative solvent. water.
4.3 Simulated leaching
The leaching is carried out using the liquid 1) which is the most unfavorable clinical contact, and the leaching method and conditions, and then the part is taken. The extract is used as a test solution.
Due to the large difference in the clinical use of the device, especially the actual contact medium of the infusion device is varied,
