Abstract: A stacked package structure and a manufacturing method thereof are provided. The stacked package structure includes an upper redistribution layer, a first chip, and an upper molding layer. The first chip is disposed on the upper redistribution layer and is electrically connected to the upper redistribution layer. The upper molding layer is disposed on the first chip and the upper redistribution layer, and is configured to package the first chip. The upper molding layer includes a recess, the recess is recessed relative to a surface of the upper molding layer away from the upper redistribution layer, and the recess is circumferentially formed around a periphery of the upper molding layer.

Abstract: A disposable pre-filled syringe has a protecting tube, a medication filling tube, a separating plug, a pushing module, and a needle module. The medication filling tube is made of chemically inert material and is mounted in the protecting tube. The separating plug is mounted in an end of the medication filling tube. The pushing module is slidably inserted into the medication filling tube opposite to the separating plug. The needle module is mounted on an end of the protecting tube.

Abstract: A safety syringe has a barrel, a pushing element, a retracting element, and a needle group. The barrel is hollow and has a needle-group mounting end, an operating grip end, and a barrel lumen. The pushing element is retractably mounted in the barrel lumen and has a pushrod chamber. The retracting element is airtightly and slidably mounted in the pushrod chamber. The needle group is connected to the needle-group mounting end of the barrel. The present invention can pull the retracting element to move relative to the pushing element to form a low pressure condition in the pushrod chamber as a vacuum status. After the injection, a vacuum attraction force in the pushrod chamber can retract the used needle group into the pushrod chamber for safe use of the safety syringe.

Abstract: A needle protecting module of an injection device in connecting with a syringe has a needle base, a needle body a tube module, a mounting tube, an elastic unit, and a stopping unit. The syringe has a tube body and an axis. The needle body transfixes the needle base and communicates with the tube body for medication injection. The needle base is removably engaged with the tube body and bearing the needle protecting module is transfixed by the needle body. The tube module is mounted around the needle base and has an annular space. The mounting tube is movably inserted into the annular space. The elastic unit is mounted in the annular space and abuts both the mounting tube and the needle base bilaterally. The stopping unit is moveably mounted in the annular space and is selectively engaged with the mounting tube.
