When 50 syringes are used, 1.99ml-4.53ml. 5 Muscle is deeper than skin, so the needle used for these shots must be thicker and longer.
As an example, a reasonable amount of hub loss from a vial when 10 syringes are used is 0.1ml-1.07ml. Intramuscular injections go directly into a muscle. Based on our data, a reasonable range of hub loss depends on the number of syringes used to draw from a single vial, with the volume per draw not significantly affecting hub loss. of 0.26 mm while the 26s gauge needle has an O.D. For example, a 26 gauge needle has an O.D. (inner diameter) for the needle and a thicker needle wall for better durability. The aim of this study was to establish a reasonable range of hub loss to monitor the usage of controlled substances. Note: The ‘s’ on a 22s needle represents a smaller I.D. The inconsistency may have been due to real world variables such as imprecise starting vial volumes, interpersonal variability, air bubbles, and unstable pressure within vials. These wide ranges display inconsistent amounts of hub loss per vial. For the deltoid muscle route, the needle gauges are 22 to 25 with a length of 5/8 to 1 inch. Of the recorded hub loss, the range of all datasets ranged from 0.1 to 2.9. When 10 syringes were used to draw out half of a 10ml vial, there was a mean of 0.5ml of hub loss. When 50 syringes were used to draw out half of a 10ml vial, there was a mean of 3.3ml of hub loss. The trend of these tests showed an increase in hub loss as the number of syringes used increased. After calculating the hub volume of each syringe, we tested expected hub loss from 10ml and 20ml vials. The hubless tuberculin syringe had a mean of 0ml of hub loss. The two conventional 1ml syringe types used had means of 0.068ml and 0.066ml of hub loss. Prior to finding the hub loss per vial, we calculated the hub volume of three different syringe and needle types. Additionally, we tested the effects of interpersonal variability, number of syringes used per vial, volume drawn up in each syringe, and other real world conditions. We calculated and measured the hub volume using a variety of different syringes and vial volumes to determine the anticipated substance loss. Little information is known about the true amount of hub loss that is expected from a given vial of controlled substances. As a result, the substance remaining in the hub is inevitably wasted and difficult to account for. Improvement of needle-point sharpness and improved injection comfort for patients remain active areas of research. This space collects liquid that once drawn up, cannot be plunged out.
The design of a conventional syringe includes a dead space between the needle and barrel of the syringe called the hub. The syringe enables accurate measuring of the liquid and an easier way to get a young child to swallow the oral medication than a medicine cup or pill.
