The New Delhi factories have been producing 2.5 billion syringes a year, increasing their capacity because of the coronavirus pandemic. Two thirds of the capacity is for the market in India but there is global demand, increased by stockpiling, from the US and Europe where investment focused on the vaccine development rather than syringe ...
Triacetin is the organic compound with the formula C 3 H 5 (OCOCH 3) 3.It is classified as a triglyceride, i.e., the triester of glycerol with acetic acid. [6] It is a colorless, viscous, and odorless liquid with a high boiling point and a low melting point.
This space can be as high as 84 micro liters in conventional syringes. [2] Conventional high dead space syringes have existed since the mass production of plastic syringes with removable needles in 1961. [3] However, there are problems associated with the dead space in syringes: medication waste, [4] disease transmission, [2] and inaccurate ...
Automatic syringes are known since the 1910s, [2] and many spring-loaded devices with needle protectors were patented in the first half of the 20th century, [3] but it was not until 1970s when they became economically feasible to mass-produce (simple syrettes were used instead before).
Glycerin suppositories for insertion into the rectum. A rectal "bulb" syringe for introducing a small amount of fluid into the rectum. Enema equipment for introducing a large amount of fluid into the colon via the rectum.
There are many types of safety syringes available on the market. [2] Auto Disable (AD) syringes are designed as a single use syringe, with an internal mechanism blocking the barrel once depressed so it cannot be depressed again. The other type of syringe with a re-use prevention feature is the breaking plunger syringe.

Like a ground glass stopcock, the two parts of a gas syringe should preferably not be interchanged with another gas syringe of the same volume, unless told otherwise by the distributor. [3] Gas syringes come in various sizes from 500 ml to 0.25 ml and tend to be accurate to between 0.01 and 1 ml, depending on the size of the syringe. [4]
