[0103] The drug delivery system 2 provides power to deliver the drug solution. Simultaneously, by adjusting the position of the ocular drug delivery device, a height difference is created between the liquid level in the drug storage system 4 and the eye area. This height difference generates static pressure-assisted drug delivery. The drug storage system 4 includes, but is not limited to, a reservoir. For static pressure-assisted drug delivery, the drug storage system 4 is secured to the patient's head or an area above the eye using a wearable, bracket-like, or mounted structure. This creates a height difference ΔH between the liquid level in the reservoir and the eye area. This height difference ΔH generates a static pressure P = ρgΔH, where ρ is the density of the drug solution and g is the acceleration due to gravity. This pressure is then delivered to the eye area via the drug delivery system 1. In this embodiment, the reservoir of the drug storage system 4 is positioned above the eye. A liquid level sensor is located at the bottom of the reservoir to monitor the liquid level in real time and provide feedback of the ΔH value to the control unit of the control module 3 to ensure the stability of the static pressure-assisted delivery. When the ΔH value falls below a threshold, the control unit triggers an alarm, which indicates that the height adjustment is required. According to other embodiments of the present invention, the liquid reservoir may also be located at a position relatively at the same height as the eyes or at a position lower than the eyes.
[0104] The control device of the ocular drug delivery device controls the drug delivery system 2 in a manner including, but not limited to: wireless remote control, wired connection and / or independent operation to adapt to different usage scenarios and user needs.
[0105] Wireless remote control methods include, but are not limited to, optical communication, acoustic communication, and / or electromagnetic wave communication; communication protocols include, but are not limited to, Bluetooth, Wi-Fi, Zigbee, or Near Field Communication (NFC). Users can establish a wireless connection with the device via a smartphone, tablet, and / or dedicated remote control to remotely set the dosing regimen, adjust parameters, and monitor status.
