Medication is prefilled into the syringe barrel. When the plug at the end of the barrel is advanced to the head of the barrel it discharges and releases the contents through the needle or into the lumen of the tubing. The carpuject competed with the tubex injection system developed by Wyeth. It has been redesigned several times to comply with ...
Researchers developed a new jet injection design by combining the drug reservoir, plunger and nozzle into a single-use disposable cartridge. The cartridge is placed onto the tip of the jet injector and, when activated, a rod pushes the plunger forward. This device is known as a disposable-cartridge jet injector (DCJI). [2]
Luer taper, a standardized fitting system used for making leak-free connections between syringe tips and needles. Needle exchange programme , is a social policy based on the philosophy of harm reduction where injecting drug users (IDUs) can obtain hypodermic needles and associated injection equipment at little or no cost.
Microneedles (MNs) consist of micro-sized needles arrays that are made of various materials exhibiting different characteristics and are suitable in the synthesis of different types of MNs. The selection of materials for formation of MNs greatly depends on the strength of skin penetration, manufacturing method, and rate of drug release.
An inoculation needle is an essential tool in inoculating a stab culture. [4] [7] A sterile stab culture cap is removed and the open end is flamed. The needle tip and its length is then pushed into the stab media and stopped once the needle tip reaches 0.5 inches away from the bottom of the stab media. [7]
A syringe with a male luer lock fitting, and a needle with female luer lock fitting (purple) which screws into it. The Luer taper is a standardized system of small-scale fluid fittings used for making leak-free connections between a male-taper fitting and its mating female part on medical and laboratory instruments, including hypodermic syringe tips and needles or stopcocks and needles.
The needles are generally manufactured with an outer protective plastic shell, which is used by a person to attach the needle to the pen, and an inner plastic shell protecting the needle itself. Instruction on how to properly attach and use needles is the responsibility of the doctor or pharmacist to ensure proper use. [2] [7]
Hypodermic needles are normally made from a stainless-steel or Niobium tube [17] through a process known as tube drawing where the tube is drawn through progressively smaller dies to make the needle. The end of the needle is bevelled to create a sharp pointed tip, letting the needle easily penetrate the skin. [18] A hypodermic needle tip under ...
