Title: Needle unloading device capable of greatly reducing needle stick injury risk to increase safety and efficiency of executing operaiton
Inventor: Qu fu-ling
IPC: A61M5/32
Filed: 2021-10-06
Abstract: The invention provides a needle unloading device for unloading needles of recovery syringes and drip infusion cannulas. The needle unloading device includes a needle unloading cover, a collection box, and a cover. The needle unloading cover has functions of rotating and cutting the unloaded needle at the same time. The needle unloading device defines a needle unloading hole with a rubber ring so that the needle can be unloaded through rotation. The needle unloading device includes a cutting knife set disposed in the needle unloading cover and having fixed stop blocks that are sandwiched in pairs to form a trapezoidal space. Tool carriers are symmetrically arranged in the trapezoidal space and can slide along the fixed stop blocks. A cutting knife is mounted on the tool carriers. An elastic element is fixedly disposed between the tool carriers or between the tool carrier and the needle unloading cover to provide a restoration force. One end of a pressing component is configured to push the tool carrier while the other end is exposed to the needle unloading cover. A fixed rail is disposed on an inner surface of the collection box. The cover is placed outside the collection box when it is not in use. The cover passes through a cover hole of the collection box to place it on the fixed rail while removing the needle unloading cover and the collection box, preventing needle stick injury risks caused by removing the needle unloading cover. Accordingly, the invention can effectively resolve the needle stick injury while removing needles in the existing nursing operations. At the same time, the needle unloading cover can be repeatedly used with the collection box to reduce costs.

Abstract: Some image sensors include pixels with capacitors. The capacitor may be used to store charge in the imaging pixel before readout. The capacitor may be a metal-insulator-metal (MIM) capacitor that is susceptible to dielectric relaxation. Dielectric relaxation may cause lag in the signal on the capacitor that impacts the signal on the capacitor during sampling. The image sensor may include dielectric relaxation correction circuitry that leverages the linear relationship between voltage stress and lag signal to correct for dielectric relaxation. The image sensor may include shielded pixels that operate with a similar timing scheme as the imaging pixels in the active array. Measured lag signals from the shielded pixels may be used to correct imaging data.
