摘要： A syringe has a retractable needle and a barrel having an open proximal end and an open distal end defining a receiver with an inward shoulder. The barrel has a hollow bore, an elongate plunger with a proximal end and a distal open end with a cavity therewithin. A stopper occludes the open end of the cavity. The syringe has an elongate hub with a proximal flange. The hub is within and sized for slidable movement within the receiver at the distal end of the barrel with the flange defining a distal end of a chamber. There is a sleeve sized to fit with a clearance about the hub disposed between the shoulder and the flange when the hub is in the receiver, the sleeve having a sharpened proximal end disposed against the flange. The needle has a pointed distal end and a proximal end connected to the passageway of the hub with the pointed end of the needle extending outwardly. There is a spring disposed about the hub compressed to provide a bias between the receiver and the flange so that when a force greater than required to expel fluid from the chamber is applied, the plunger causes the cutting surface to cut through the flange and stopper and expose the cavity to allow the spring to urge the hub into the cavity in the plunger and retract the needle to a position within the syringe.
摘要翻译：注射器具有可缩回的针和具有敞开的近端的筒体和限定具有向内的肩部的接收器的敞开的远端。桶具有中空孔，具有近端的细长柱塞和具有其中的腔的远端开口端。塞子封闭空腔的开口端。注射器具有带近端凸缘的细长毂。轮毂位于筒体的远端处的接收器内滑动运动的内部并且具有尺寸，其中凸缘限定了腔室的远端。当轮毂在接收器中时，存在一个套筒，该套筒的尺寸适于围绕设置在肩部和凸缘之间的毂的间隙，套筒具有靠近凸缘设置的尖锐的近端。针具有尖的远端和连接到轮毂的通道的近端，针的尖端向外延伸。有一个弹簧设置成围绕毂被压缩以在接收器和法兰之间提供偏压，使得当施加大于从腔室排出流体所需要的力时，柱塞使切割表面穿过凸缘和塞子，并且暴露空腔以允许弹簧将毂推入柱塞中的空腔中并将针缩回到注射器内的位置。

摘要： A hypodermic syringe with a selectively retractable includes an elongate barrel having an open proximal end and a distal end that defines a receiver with an inwardly projecting shoulder. The syringe has a hollow elongate plunger with an open proximal end and a closed distal end. There is an elongate plug extending distally into the hollow plunger from the open proximal end forming an enclosed cavity within the plunger. The syringe has an elongate hub having a passageway therethrough, a distally extending stem, and a proximal flange with an engagement for engaging said barrel. The syringe has an elongate needle having a fluid path therethrough, a sharpened distal end and a proximal end. The needle is mounted in the passageway so that the sharpened distal end projects. The syringe has an elongate spring disposed about the stem of the hub that is compressed between the flange and the inwardly projecting shoulder of the receiver to provide a bias. There is a hollow sleeve sized to fit within the receiver over the elongate spring with a proximal sharpened end disposed in the groove of the flange. When a user applies a sufficient force, the hub is sufficiently moved distally in the receiver for the cutting edge of the sleeve to cut through the flange and the closed distal end of the plunger to expose the cavity for withdrawal of the needle into the syringe.

摘要： A retracting needle assembly for use with a syringe barrel having a distally-facing annular sealing surface includes an outer hub having a conduit therethrough, a proximally facing annular sealing surface and means for connecting the outer hub to the syringe barrel. An inner hub having a passageway therethrough is provided. The inner hub includes a distally extending stem and a proximal flange for releasably engaging the outer hub. A needle having a sharp distal end and a proximal end is mounted in the passageway of the inner hub so that the sharp distal end projects distally outwardly. An elongate spring is disposed about the stem of the inner hub and is deflected to provide a bias between the inner hub and the outer hub. A hollow sleeve sized to fit within the conduit of the outer hub over the spring is provided. The sleeve has a sharp edge at its distal end for cutting through the flange to activate the retracting needle feature.

摘要： A hypodermic syringe with a selectively retractable needle includes an elongate barrel defining a receiver and a hollow bore. The syringe has a plunger with an elongate cavity open to the proximal end. The plunger is sized to fit within the bore of the barrel for a slidable movement to define a chamber for receiving and expelling fluids. The inside diameter of the cavity in the plunger is sufficient to accept telescopically at least a part of a first portion of the plunger. A second portion and the first portion are joined at an attachment to form a shoulder extending outwardly from the first portion, with the plunger being telescopically collapsible by movement of the second portion into the cavity by of sufficient distal force to frangibly disrupt the attachment. The syringe includes an elongate sleeve sized to fit over the first portion of the plunger and extend from the shoulder. The plunger includes a stopper to a form fluid tight seal with the barrel. The sleeve has a cutting surface inside of the stopper. The syringe includes a hub with a proximal flange and a passageway within the receiver. The syringe has a needle with a pointed distal end mounted in the passageway of the hub extending distally outwardly. When sufficient distal force is applied to collapse the plunger, the cutting surface of the sleeve cuts through the stopper and through the flange of the hub and releases it from the receiver to retract the needle.
摘要翻译：具有可选择性缩回针的皮下注射器包括限定接收器和中空孔的细长筒。注射器具有柱塞，其具有向近端开口的细长空腔。柱塞的尺寸设置成装配在筒的孔内以进行可滑动运动，以限定用于接收和排出流体的室。柱塞中的空腔的内径足以可伸缩地接收柱塞的第一部分的至少一部分。第二部分和第一部分在附件处连接以形成从第一部分向外延伸的肩部，其中柱塞通过足够的远端力使第二部分进入空腔而被可伸缩地收缩，以易于破坏附件。注射器包括细长的套筒，其尺寸适于装配在柱塞的第一部分上并从肩部延伸。柱塞包括一个止动件，以形成与桶相当的流体密封。套筒在塞子内部具有切割表面。注射器包括具有近侧凸缘和接收器内的通道的毂。注射器具有安装在毂的通道中的尖端远端的针向远侧向外延伸的针。当施加足够的远端力以使柱塞塌陷时，套筒的切割表面穿过止动器并穿过毂的凸缘并将其从接收器中释放出来以使针头收缩。

摘要： A dynamic subsidence plate is described having a first plate member and a second plate member in sliding engagement that may infinitely subside between a first and second assembled position. The plate includes a lock assembly associated with the first and second plate members. The lock assembly includes a ramp portion, an interference portion, and a bearing member situated between the ramp portion and the interference portion. The lock assembly of the plate is configured to allow movement of the first member with respect to the second member in a first direction in an infinite number of positions between a first assembled position and a second assembled position. Further, the lock assembly alternatively prevents movement of the first member with respect to the second member in an opposite second direction between the first and second assembled positions.
