    • A blood collection assembly for receiving a blood sample from a patient but for preventing the blood from flowing out once it has been received. This assembly includes an evacuated receptacle, such as a blood collecting tube, for the reception and retention of a sample of blood. An opening is included in the receptacle into which a penetrable stopper is sealably positioned to maintain the evacuated condition inside the receptacle. Located inside the evacuated receptacle is a unidirectional flow valve through which blood entering the receptacle must pass. When the stopper is penetrated by a sharp cannular instrument carrying blood the pressure on the side of the valve facing the stopper is greater than the pressure in the evacuated receptacle, thereby causing the valve to open so that blood flowing from the instrument flows through the valve and into the receptacle. If the pressure in the receptacle changes so that it is greater than the pressure on the other side of the valve, the valve is operable to close to thereby prevent blood from backflowing into the patient.
    • 一种用于从患者接收血液样本但用于防止一旦接收到血液而流出的血液采集组件。 该组件包括用于接收和保留血液样本的抽真空的容器,例如采血管。 在容器中包括开口,其中可穿透的塞子被密封地定位,以将抽空状态保持在容器内。 位于抽真空的容器内的是一个单向流量阀,血液进入容器必须经过。 当塞子被携带血液的尖锐的管状仪器穿透时,面向塞子的阀侧的压力大于抽真空的容器中的压力,从而导致阀打开,使得从仪器流出的血液流过阀门 并进入容器。 如果容器中的压力变化使得其大于阀的另一侧上的压力,则阀可操作以关闭,从而防止血液回流到患者体内。

    • A hypodermic syringe assembly comprises a barrel with an axial bore, a hollow tip integral with the barrel having an internal surface defining a passageway communicating with the axial bore and also having a tapered external surface adapted to mate with the female tapered surface of a conventional needle hub, a needle hub having a bore therethrough removably positioned in and occupying substantially the entire volume of the passageway and a hollow needle secured within the bore of the hub in fluid communication with the axial bore of the barrel. The syringe assembly may be used with the unique hub positioned within the passageway to provide a substantially air-free syringe or the hub and needle may be removed from the tip to permit a conventional needle hub to be placed thereon.
    • 皮下注射器组件包括具有轴向孔的筒,与筒一体的中空尖端,其具有限定与轴向孔连通的通道的内表面,并且还具有适于与常规针的阴锥形表面配合的锥形外表面 轮毂,具有穿过其可拆卸地定位在并且占据通道的整个体积的孔的针孔;以及固定在毂的孔内的空心针,其与筒的轴向孔流体连通。 注射器组件可以与定位在通道内的独特的轮毂一起使用,以提供基本上无空气的注射器,或者可以从尖端移除轮毂和针,以允许常规的针座放置在其上。

    • An intravenous catheter assembly for use in the administration of fluids to a patient includes a compressible, flexible hub having a bore therethrough. One end of the bore is adapted to receive a hollow tube such as an intravenous catheter so that fluid is flowable through the bore and the tube. A pair of generally oppositely extending wing sections is connected to the hub, at least one of the wings being hingedly connected to the hub to allow that wing to fold over the hub. On the hingedly connected wing is a pinching protuberance for contact with the hub when the wing is folded thereover whereby, in use, the folded wing urges the protuberance against the flexible hub causing it to collapse and occlude the bore and thereby restrict fluid from passing therethrough.
    • 用于向患者施用流体的静脉内导管组件包括具有穿过其中的孔的可压缩柔性轮毂。 孔的一端适于容纳诸如静脉导管的中空管,使得流体可以通过孔和管流动。 一对大致相对延伸的翼部连接到轮毂,至少一个翼铰接地连接到轮毂,以允许翼折叠在轮毂上。 在铰接连接的机翼上,当机翼折叠在其上时,是用于与轮毂接触的夹紧突起,由此,在使用中,折叠的翼将突起推动抵靠柔性轮毂,从而使其塌陷并闭塞孔,从而限制流体从其中穿过 。

    • A self-packaged medical device has a hollow body and an operative element inside for controlling the dispensing of fluids from the device. A handle, partly inside and partly outside of the body is connected to the operative element and is provided with a frangible seal at the point where the handle passes through a hole in the wall of the body. This seal allows maintenance of cleanliness of the interior of the body during storage, but does not interfere with the use of the handle to operate the element within the body once the seal is broken. The seal is formed by a continuous, frangible film adhering to the body and the handle, and is broken by motion of the handle, whereupon the device is ready for use. A hydrodermic syringe is desirably self-packaged in this fashion.A method of making a self-packaged hypodermic syringe includes assembling a piston, with a piston rod connected to it, into a bore of a tubular barrel so that the rod extends out of the barrel. A clearance space is left between the rod and the inside wall of the barrel. This assembly is dipped, piston rod extension facing downward, into a bath of curable liquid plastic to a sufficient depth to cause a column of liquid plastic to rise into the clearance space in the barrel. Following withdrawal of the assembly from the bath, the liquid plastic is cured to a solid form, thereby providing a seal for the self-packaged syringe.
    • 自包装医疗装置具有中空体和内部的操作元件,用于控制来自装置的流体分配。 部分内部和部分在身体外部的手柄连接到操作元件,并且在手柄通过身体的壁中的孔的点处设置有易碎密封件。 该密封件允许在储存期间维持身体内部的清洁度,但是一旦密封件破裂,则不会干扰使用手柄来操作元件。 密封件是由连续易碎的胶片形成的,粘贴在主体和把手上,并被手柄的运动所破坏,于是该装置准备使用。 流体动脉注射器理想地以这种方式自包装。 制造自包装皮下注射器的方法包括将活塞与其连接的活塞杆组装成管状筒的孔,使得杆延伸出筒体。 杆和桶的内壁之间留有间隙。 该组件将活塞杆延伸面向下浸入可固化液体塑料浴中至足够的深度,使一列液体塑料进入筒体的间隙空间。 在将组件从浴中取出之后,液体塑料固化成固体形式,从而为自包装注射器提供密封。

    • A polymeric tube for a medical catheter is provided with elongated metal stripes extending lengthwise along the tube by illuminating the exterior surface of the tube patternwise and treating metal responsive to the illumination. The tube may be covered with a photoresist and moved axially past a plurality of light beams while rotating the tube about its axis so as to form a helical pattern. After development of the photoresist, the metal is deposited or removed in a pattern corresponding to the pattern formed in the photoresist, so as to leave helical metallic stripes. The metallic stripes may have varying helical pitch, varying width or both along the length of the tube, and may serve as electrical connectors and physical reinforcements for the tube wall.
    • 用于医疗导管的聚合物管设置有沿着管长度方向延伸的细长金属条,通过以图案方式照亮管的外表面并且响应于照明来处理金属。 管可以被光致抗蚀剂覆盖并且沿着其轴线旋转管以轴向移动通过多个光束以形成螺旋图案。 在光致抗蚀剂显影后,以对应于在光致抗蚀剂中形成的图案的图案沉积或去除金属,以便留下螺旋状的金属条纹。 金属条可以沿着管的长度具有变化的螺距,变化的宽度或两者,并且可以用作管壁的电连接器和物理增强件。
