Abstract: A dropper syringe apparatus includes a cylindrical barrel, a plunger assembly, and a needle. The cylindrical barrel storing the fluid includes a flanged first opening and a second opening. The plunger assembly, inserted into the cylindrical barrel, includes a plunger shaft and a flexible hollow bulb. The plunger shaft includes a flanged upper end, a lower end, and a central lumen. The plunger shaft moves in an upward and a downward direction within the cylindrical barrel. The central lumen extends from the lower to the flanged upper end of the plunger shaft for accommodating the fluid. The flexible hollow bulb is fixedly attached to the flanged upper end and in fluid communication with the central lumen. An external force exerted on the flexible hollow bulb exerts a pressure on the fluid accommodated within the lumen. The needle draws or dispenses the fluid from or to the external body.

Abstract: A system for delivering an injection of a fluid into a void within a subject is disclosed. A barrel extends from a first end to a second end and forms a lumen extending from the first end to the second end. A plug and a floating seal are arranged within the lumen. A hollow needle includes a distal end with an opening for fluid to flow from the lumen. The plug, the barrel and the floating seal include material and dimensions selected based on a threshold flowrate for a fluid arranged within the lumen to: overcome a force opposed to a force being applied to the fluid in the lumen to move the floating seal and the hollow needle into a tissue of the subject, and succumb to the opposing force to displace the fluid through the opening into the void.

Abstract: 一种药物输送装置的防退机构，包括设置在推杆（4）上的卡槽、设置在药物输送装置内的卡位凸块（6）以及具有嵌入卡位凸块（6）的容纳腔的抱紧槽（7），其中，卡位凸块（6）设置在具有缺口的套环上且能够在受到挤压的情况下相对于推杆（4）抱紧。卡位凸块（6）能够在受到药物输送装置上筒架（1）的反推力时向注射相反方向移动，嵌入抱紧槽（7）抱紧并与卡槽以勾挂方式相连接锁死。该防退机构，由于药物输送装置上的筒架（1）受到挤压，使卡位凸块（6）位置产生变化，卡位凸块（6）被推入抱紧槽（7）中与卡槽抱紧，最终实现卡位凸块（6）与卡槽以勾挂方式相连接锁死来达到紧固防退、抱紧效果，以此预防出现推杆（4）倒退现象。

Abstract: A multi-piece plunger configured to be slideably advanced through a syringe barrel to expel fluid therefrom is provided. The plunger includes a head portion having a proximal end, a distal end, and an annular sidewall extending therebetween. The sidewall can define at least two annular grooves. The plunger also includes annular seals disposed within each of the at least two annular grooves, such that at least a portion of each of the annular seals protrudes radially beyond an outer surface of the sidewall to form a slideable seal with an inner sidewall of the syringe barrel. The head portion can be formed from a first material, such as a rigid plastic material, and the annular seals can be formed from a second material, such as a thermoset rubber or a thermoplastic elastomer. A prefilled syringe including the multi-piece plunger is also provided herein.

Abstract: An apparatus includes a syringe body, a plunger, a cap, and a dose gauge. The syringe body defines a volume configured to contain a medicament. The dose gauge is disposed about at least a portion of a side wall of the syringe body, and defines a window. The cap is coupled to a proximal end portion of the syringe body, and includes an engagement portion. The plunger has a distal end portion configured to move within the volume to convey the medicament. An engagement portion of the plunger is configured to interface with the engagement portion of the cap to prevent rotation of the plunger about a longitudinal axis of the plunger. An outer surface of the plunger includes a series of indicia. At least one of the indicium is visible through the window when the plunger is in a first position within the volume.
