Embodiments of a present disclosure relate to a drug injection device and more particularly to an electronic smart syringe.
Many drugs are intended to be administered parenterally, because they are not resorbed sufficiently. A typical example includes peptide drugs like insulin. The pharmacological half-life of such drugs is very short which leaves the need for multiple daily injections. An insulin-dependent diabetic patient needs to inject multiple times a day at variable doses, adjusted to food intake and physical activity. Therefore, often the injections are performed by the patient himself instead of trained medical professionals. However, old age people may not be able to adjust the dosage of the insulin or end up wrongly adjusting the insulin dosage. Hence, to comfort the patients while dealing with frequent variable dose, variety of self-administrations drug delivery devices have been introduced. Also there are 0.5 to 1% patient deaths are due to wrong anaesthesia administered, and its not clear who administered the dosage and how much dosage was recommended based on age, weight or the like, with the currently available syringes in the market.
One such kind of self-administration drug delivery device is called “insulin pen”. Such pens are critical medical devices for the reason that both an overdose and under dose may lead to severe health problems including death. Also, such injection pen facilitates the multiple injections required. However, using such pens it is difficult and cumbersome for the patient to keep records of all parameters determining the insulin dose adjustment and dosage administered record. Also, such insulin pen does not notify to the condition of the insulin pen like the quantity of insulin or likes left, usage of the needle, last dosage, next dosage due, over dosage, under dosage, missed dosage and the like. Similarly, the insulin pen does not alert over missed or excess dosage to the patient or to their kith and kin and does not have an interface with the smart phone to send notifications to Kith and Kin, healthcare providers and to self. electronic smart syringe
Furthermore, currently available self-administration drug delivery device has security issues, as any unauthorised person may use the insulin pen to harm the patient.
Hence, there is a need for an improved electronic smart syringe to address the aforementioned issue(s).
In accordance with an embodiment of the present disclosure, an electronic smart syringe is provided. The electronic smart syringe includes a barrel. The barrel includes a slot on a proximal end. The electronic smart syringe also includes a needle coupled on a distal end of the barrel.
