Nowadays, there are many kinds of prefilled syringe products on the market, with different quality. So how can we choose the most suitable prefilled syringe scientifically? Now make the following brief analysis based on some of its characteristics:
First of all, the current prefilled syringes are mainly made of glass and plastic materials. Plastic prefilled syringes are gradually replacing glass prefilled syringes, which mainly have lower cost and higher safety than glass syringes, and it is not easy Broken, relatively high-quality infusion products have a relatively advanced production technology, generally speaking, injection molding technology is used to produce infusion products. The products produced by the injection molding process are molded at one time, with no leftovers, accurate product size and uniform weight.
Second, the pre-filled syringe has high requirements on the tightness. When selecting the infusion device, it should be tested for its tightness. Inject half of the water into the infusion device, insert the piston into the syringe, remove the protective cap, and eliminate residual air. Then block with a protective cap, and apply an axial pressure of 30N on the push rod rubber plug inside the syringe through the push rod, and keep it for thirty seconds. There should be no leakage at the seal of the protective cap and the piston seal.
Third, the pre-filled syringe must be in direct contact with the drug, so its sterility must be guaranteed. Generally, the infusion device should be produced in a clean workshop that meets national standards. In addition, in order to ensure its sterility, if the veterinary drug manufacturer is For higher requirements, additional ethylene oxide sterilization or cobalt 60 irradiation sterilization can be performed.
In the course of clinical treatment of diseases, injection is usually used for treatment. The injection method is a method of administration that uses a syringe to directly inject the liquid medicine into the body. It mainly has the advantages of precise dosage, rapid effect, avoiding the trouble of oral administration and reducing the efficacy of medicine. The most commonly used syringes are plastic syringes.
The common capacity of plastic syringes are mainly 5, 8, 10, 20, 30, 60ml and other specifications. If a large volume injection is used, a larger infusion bottle is generally used. Plastic syringes are divided into different models according to their inner diameter and length. When using, select the appropriate plastic syringe according to the animal type and the injection dose, and check whether the plastic syringe is damaged, whether the syringe and the push rod fit well, and whether there is any leaking of the seal.
It is necessary to carefully check the quality of the medicine before injection, whether there is any deterioration, turbidity, or precipitation. If two or more liquid medicines are mixed, attention should be paid to whether there are any contraindications.
