retracting the needle shield in a first direction toward the body of the needle-based device to apply a first force in the first direction to cause the needle to emerge out of the needle shield to prepare the needle-based device for a second state of use thereof;

transitioning the needle-based device back to the first state of disuse thereof following the second state of use in accordance with applying a second force in a second direction diametrically opposite to the first direction;

securedly maintaining the encompassing of the entire protruding length of the needle by the needle shield in the first state of disuse of the needle-based device based on a coupling between the needle shield and the body of the needle-based device;

providing a lock button with a first end, the first end is either integrally formed with the needle shield or external to the needle shield and then coupled to the needle shield, and a length of the lock button is completely external to the needle shield; and

locking the needle shield with the lock button in the first state of disuse of the needle-based device based on:

the lock button comprising a hook at a second end thereof that passes through a groove formed on the needle shield and locks directly onto a top of the needle mount from which the needle protrudes such that, in the state of the locking of the needle shield:

the length of the lock button completely external to the needle shield is parallel to a length of the needle shield and the entire protruding length of the needle, and

the hook is perpendicular to the length of the needle shield, the length of the lock button and the entire protruding length of the needle.

10. The method of claim 9 , comprising the coupling between the needle shield and the body of the needle-based device being based on providing wings on lateral sides of one of: the needle mount and the body of the needle-based device.

11. The method of claim 9 , comprising the second state of use encompassing drawing of a fluid via the needle-based device.

12. The method of claim 9 , comprising the second state of use encompassing injection of a fluid via the needle-based device.

13. The method of claim 9 , comprising the coupling between the needle shield and the body of the needle-based device being based on providing a ring on an outer wall of one of: the body of the needle-based device and a body of the needle mount.

14. The method of claim 9 , comprising the coupling between the needle shield and the body of the needle-based device being based on providing a connector on one of: the body of the needle-based device and a body of the needle mount.

15. A method comprising:

protecting an entire length of a needle of a needle-based device protruding from a needle mount coupled to a body of the needle-based device based on providing a needle shield completely encompassing the entire protruding length of the needle in a first state of disuse of the needle-based device;
