摘要： In one aspect, a safety pen needle assembly is provided herein which includes a hub with a needle fixed to the hub, the needle having a distal end, formed for insertion into a patient, and a proximal end. The assembly further includes a shield and a biasing member disposed between the hub and the shield configured to urge the shield distally. A protrusion extends from at least one of the hub and the shield with a channel being formed in at least the other of the hub and the shield. The channel is formed to accommodate the protrusion. The shield is movable from a first position to a second position. In the first position, the shield is spaced from the distal end of the needle such that the distal end of the needle is exposed. In the second position, the shield covers the distal end of the needle. The channel guides the protrusion as the shield moves from the first position to the second position. With this arrangement, a shield may be directed to move in a desired path with stability. In addition, the distal end of the needle may be initially exposed to permit visual confirmation of priming, while allowing the shield to cover a majority of the needle to minimize any needle-related anxiety.
摘要翻译： 在一个方面，本文提供一种安全笔针组件，其包括具有固定到轮毂的针的轮毂，所述针具有形成用于插入患者体内的远端和近端。 组件还包括屏蔽件和设置在毂和屏蔽件之间的偏压构件，其构造成向远侧推动屏蔽件。 突起从毂和屏蔽件中的至少一个延伸，其中通道形成在毂和屏蔽件中的至少另一个中。 通道形成为容纳突起。 护罩可以从第一位置移动到第二位置。 在第一位置，护罩与针的远端间隔开，使得针的远端露出。 在第二位置，护罩覆盖针的远端。 当护罩从第一位置移动到第二位置时，通道引导突起。 利用这种布置，屏蔽可以被引导以在所需的路径中稳定地移动。 此外，可以最初暴露针的远端以允许目视确认起动，同时允许护罩覆盖大多数针以最小化针头相关的焦虑。

摘要： A safety pen needle assembly is provided herein which includes a hub and a needle fixed to the hub. Further, a first shield is provided, along with a second shield which has a biasing element disposed to urge the second shield proximally towards a proximal end of the needle. The assembly further includes a releasable retaining assembly for releasably retaining the second shield in an initial position against the force of the biasing element. A predetermined extent of movement of the first shield causes the retaining assembly to release the second shield, and, wherein, with the second shield being released, the second shield is urged proximally by the biasing element to a second position where the second shield covers the proximal end of the needle. Advantageously, with the subject invention, an assembly is provided which allows for passive activation of a shield on a non-patient end of a pen needle assembly by a patient-end shield.

摘要： A safety pen needle assembly is provided herein which includes a hub; a needle fixed to the hub having a distal end, formed for insertion into a patient, and a proximal end; a shield; a biasing means disposed to urge the shield from a first position to a second position; and, at least one adjustable tab or locking finger on the hub, the tab or finger being adjustable from a first state to a second state. With the tab or finger being in a first state, the tab or finger interferingly engages the shield so as to restrict movement thereof. The tab or finger in the first state retains the shield in its first position with the proximal end of the needle being exposed. With the tab or finger being in the second state, the tab or finger does not interferingly engage with the shield. As such, the shield is permitted to be urged proximally to the second position by the biasing means. In the second position, the shield covers the proximal end of the needle. Advantageously, with the subject invention, a mechanism is provided for shielding a proximal, or non-patient, end of a pen needle, particularly after use.

摘要： A system for medication delivery comprises a package containing a medication and a dosing device for delivering a dose of the medication, formulated as a multiparticulate, microspheres, a powder or a liquid. The package comprises a bottle, a bottle insert that covers a bottle opening and includes a dispense nozzle. The dispense nozzle is sealed using a valve that opens when the dosing device is engaged with the bottle. A closure covers the bottle insert and closes the bottle. The dosing device, similar to an oral syringe, comprises a barrel with a valve at a distal end of the barrel, a plunger and a dose control clip for attachment to the plunger. After the dosing device is connected to, the valve of the dispense nozzle, withdrawal of the plunger causes the dosing device to receive the dose of the medication, a user pushes the plunger which pushes the medication through the valve of the barrel and into a patient's mouth.

摘要： A stopper adapted for attachment with a plunger rod for use within a syringe barrel is disclosed. The stopper includes a main body defining an open rearward end and a closed front end. The open rearward end is adapted to receive a front forward end attachment portion of the plunger rod. The stopper also includes a core member integrally formed with the main body adjacent the closed front end. The core member includes a nose portion having a conical tip configured for entering an outlet opening of the syringe barrel. The closed front end of the stopper has a profile configured to cooperate with an internal surface of the syringe barrel wall to prevent reflux and reduce dead space within the barrel.

摘要： A stopper adapted for attachment with a plunger rod for use within a syringe barrel includes a main body portion defining an open rearward end configured to receive the plunger rod. The main body portion is manufactured from a rigid or semi-rigid polymeric material having an elastic modulus in the range of about 0.01 GPa to about 5 GPa. When fluid pressure is increased inside the syringe barrel during an injection, at least one of the following actions occurs: a) a flexible roof of the main body portion expands in a radial direction toward an inner wall of the syringe barrel; b) a first perimetrical skirt extending around an outer circumference of the main body portion is forced against an inner wall of the syringe barrel; and c) an engagement between the plunger rod and an engagement portion provided along an inner circumference of the main body portion.

摘要： A paintball gun comprised of a simplified firing system that eliminates many of the seals and complexity of a typical gun that uses the bolt as a spool type valve. The gun contains a bolt with a gas chamber around it, one seal inside of it, and one seal on its outside. A cylinder rod inside the bolt pushes the bolt forward against a spring using pressurized gas routed via a pilot valve, moving the bolt into the fire position. In the fire position the rear of the bolt moves off the inner seal, allowing compressed gas stored around the bolt to move into and thru the bolt, firing the paintball. Releasing pressure from behind the cylinder rod allows the spring to push the bolt rearward and seal the gas chamber. The simplified mechanism should be more consistent, allow more shots per tank and require less maintenance than other guns.
