    Abstract: Low cost insulin injection syringes (20) are disclosed in which the low cost is achieved by separating the syringe into two types of components, namely, durable components that do not contact the fluid path and can be reused, and disposable or single-use components that contact the fluid path and are not reused. The ability to reuse the durable components reduces the effective per-unit cost of the syringe when multiple syringes are used. Since these components do not contact the fluid path, sterility is not affected. The disposal burden is also reduced because not all of the syringe components need to be disposed of each time a syringe is used. Two different syringe components—a reusable outer sleeve (24) containing scale markings (44) for the syringe, and a reusable syringe plunger (32)—are provided as durable components in embodiments of the present invention. Syringes (20) manufactured according to the present invention can employ one or both of these durable components. Methods for making, using and packaging such syringes are also disclosed.

    Abstract: An injection device is provided for delivering a liquid medicament. The injection device includes a housing with a first chamber for storing a supply of the medicament. The first chamber and a second chamber are coupled within the housing. The second chamber is in fluid communication with the first chamber. The system also includes an outlet port for dispensing the medicament outside the housing. The outlet port is coupled to the housing and in fluid communication with one of the first and second chambers.

    Abstract: A catheter configured to provide inherent antimicrobial properties includes a polyhydroxyalkanoate (PHA). In some embodiments, an extruded catheter body is fabricated of a PHA. In some embodiments, an extruded catheter body has an exterior layer containing PHA, an interior layer containing PHA, or both exterior and interior layers containing PHA. The PHA layer may be co-extruded with the catheter body. The PHA layer may be coating applied to the catheter body. Useful PHA materials to provide inherent antimicrobial properties include poly-4-hydroxybutyrate (P4HB) and copolymers of P4HB. The catheter may be an IV catheter, a urinary catheter, a dialysis catheter, or any other catheter introduced into a body lumen.

    Abstract: A pen needle assembly (10) includes a pen needle (12) with a hub body (16) having a needle shield (28) that covers a needle (26) and can be retracted to expose the needle during injection and return to the extended position after use and locked in the extended position. A spring (56) is provided to rotate the needle shield after use to a locked position. A locking member (84) can be provided on the needle shield that cooperates with the hub body (16) to prevent rotation after use. An attachment mechanism (38) for the pen needle provides a sensory indication when a needle-bearing hub body (16) is seated on a pen and limits further rotation of the pen needle relative to the delivery device.

    Abstract: Induction heating from an induction coil (108) is used to separate a metal medical sharp (144) from its holder (142) by applying a high-frequency oscillating magnetic field that excites eddy currents and resistance heating in the sharp. The heated metal sharp melts the adhesive or plastic securing the sharp to its holder. The use of induction heating is advantageous in that it does not require direct contact between the electrical circuit and the sharp or its holder. The heating can also act to sterilize the sharp and thereby render it less hazardous at the same time that it separates the sharp from its holder. The induction coil can have a stepped or conical shape to concentrate the RF energy at the interface between the metal sharp and its holder.

    Abstract: A pen needle is provided with a plastic non-patient end. Since the non-patient end needle does not contact the patient, the needle can be formed with a larger diameter, permitting more secure attachment to a medication pen and greater medication flow from the cartridge through the cannula. In addition, a two-part hub construction comprising a needle bearing sub assembly and an adapter for attachment to the pen body may be used to lower materials volume and costs, and reduce sharps disposal. In embodiments, a hub according to the invention may be provided with a shield that provides an audible and/or tactile indication when full penetration depth of the needle is achieved. Windows on the shield may reveal a color band on the hub at the full-penetration depth position to provide the user with a visual indication that the pen needle has been used.

    Abstract translation: 笔针设置有塑料非病人端。 由于非患者端针不接触患者，所以可以形成更大直径的针头，从而更可靠地附接到药物笔，并且从药筒通过插管获得更大的药物流动。 此外，可以使用包括滚针轴承子组件和用于附接到笔体的适配器的两部分轮毂结构来降低材料体积和成本，并且减少锐利处置。 在实施例中，根据本发明的轮毂可以设置有当达到针的全部穿透深度时提供听觉和/或触觉指示的护罩。 屏蔽上的窗口可以在全穿透深度位置处露出轮毂上的色带，以向用户提供笔针已被使用的视觉指示。

    Abstract: The subject invention provides a safety pen needle assembly which includes: a hub; a needle carrier; a needle fixed to the needle carrier; a shield; and, a first engageable locking arrangement for fixing the shield to the needle carrier. Upon a predetermined extent of distal movement of the shield relative to the hub, the first locking arrangement is engaged such that the shield becomes fixed to the needle carrier. Upon further distal movement of the shield relative to the hub beyond the predetermined extent of distal movement, the shield and the needle carrier move in concert together relative to the hub causing a proximal end of the needle to move distally relative to the hub to a retracted state. Advantageously, the subject invention provides a reliable, low-cost safety pen needle assembly which does not require a spring or other biasing element.

    Abstract translation: 本发明提供了一种安全笔针组件，其包括：轮毂; 针架; 针固定到针架上; 盾牌 以及用于将屏蔽件固定到针架上的第一可接合锁定装置。 在护罩相对于毂的预定程度的远端运动中，第一锁定装置被接合，使得护罩固定到针架上。 当护罩相对于轮毂进一步远离移动超过远程运动的预定范围时，护罩和针托架相对于轮毂相互一起移动，使得针的近端相对于轮毂向远侧移动到缩回 州。 有利地，本发明提供了一种可靠的低成本安全笔式针组件，其不需要弹簧或其它偏置元件。
