Application of Plastic-Steel Veterinary Syringes in Aquaculture Industry

Our plastic-steel veterinary syringes are made of high-quality pharmaceutical-grade plastics, resistant to various types of drugs, not easy to break, do not use corrosive metal materials, use silicon O-rings, accurate and continuously adjustable doses, comfortable and ergonomic handles , It can be installed and disassembled quickly and easily, and the filling pressure can be adjusted gently. The metal parts are made of stainless steel, which will not rust and chemically react with the liquid medicine to change the properties of the liquid medicine. The needle interface and the syringe are integrated, and no leakage will occur. The structure is simple, and each part can be disassembled, which is convenient for cleaning and disinfection.

Check for water leaks before using plastic-steel veterinary syringes. Then try to draw clean water several times; lightly press the outlet of the syringe with the index finger of the left hand, hold the cannula with the thumb and the other three fingers, and gently pull the handle with the right hand to a certain distance, you can feel a certain resistance, and then release the handle The piston can automatically return to its original position, which means that all joints are tight and there will be no water leakage, so you can use it with confidence. If there is no resistance when pulling the handle, loosen the handle, and the piston cannot return to its original position, it indicates that the connection is not tight. At this time, you should check whether the fixing screw is tightened upright, or whether the piston is too loose. until the requirements are met.

When installing the needle, you need the sterilized needle. Use medical tweezers to grab the needle seat, put it on the syringe needle seat, rotate half a circle clockwise and apply a slight downward pressure, and the needle is installed. Apply a slight outward pull to remove the needle. Pumping medicine Use vacuum to suck the medicine from the medicine container into the tube. When filling the medicine, pay attention to inject an appropriate amount of air into the container first, so as to avoid the negative pressure in the container and the medicine cannot be sucked. The filling volume is generally controlled at about 50% of the maximum filling volume. After inhaling the medicine, the needle is directed upwards to empty the air in the tube, and finally the metering bolt is adjusted to the required scale according to the required dose, and adjusted once for each animal injected.

Exhaust method: generally use the syringe upside down or pat the syringe lightly to make the air bubbles float up, and then turn the nipple of the syringe upward to exhaust the air. Another method is to make the syringe contain about one-fifth of the volume of gas after extracting the liquid medicine from the syringe, and then roll the syringe horizontally for a circle so that the air bubbles attached to the wall of the syringe can quickly fuse with the gas, and then point the needle of the syringe towards the gas. Push the air out. If it still doesn't work, try adjusting the small air inlet on the syringe.
