How to use the cassette bottle
Cassette bottle (also known as borosilicate glass sleeve for pen syringe) is mainly used in the fields of genetic engineering, bioengineering and insulin injection, etc. Its use should follow the following steps and precautions:
Preparation stage
Cassette bottle should be kept in the original packaging, room temperature (20-22 ℃) stored away from light, no special treatment before use.
If disinfection is required, only use 70% ethanol or 91% isopropanol moistened gauze to gently wipe the rubber membrane, not soak, so as not to contaminate the liquid by penetration of disinfectant.
Installation and Injection
Fit the cassette bottle into the matching fish-shaped e-pen syringe, making sure that the rubber stopper aluminium cap at the mouth of the bottle and the rubber piston at the end are sealed intact. 1
The injection requires several operations (usually 6-15) to complete the dose push, which is a cumbersome process.
Temperature control
It is sufficient to keep the medication at room temperature without the use of a thermostat. Heating may cause vasopressor failure or patient discomfort (e.g., burning sensation).
Risks and Precautions
Dislodgement or leakage of the stopper: may result in venous embolism or contamination of the medication.
Particle contamination of the stopper: Repeated puncture of the stopper may produce particles mixed with the drug solution, which may be hazardous to health after injection.
Comparison of pre-filled packaging
The cost of cassette bottles is lower, but the operation is complicated and risky; pre-filled syringes are safer and more convenient, and are suitable for drugs that require precise dosage (e.g. growth hormone).
Special applications (oral anaesthesia)
Oral ampoules (similar to cassette bottles) need to avoid high-pressure sterilisation, and the sealing wax is easily damaged by high temperature. The sealing wax is easily damaged by high temperature. When used, it can be taken out from the sealed package directly and put into the syringe.
