摘要： A trocar is disclosed which comprises a housing assembly having an upper end and a lower end and a cannula assembly attached to the lower end of the housing assembly to define an axial bore therethrough. The disclosed trocar also includes an obturator for sliding engagement in the bore. The housing assembly includes an access port formed on the upper end which is axially aligned with the bore of the trocar. Communication via the access port of the housing is regulated by a flapper valve having a closed position and a range of open positions. The flapper valve comprises a metal flapper door having a male/female configuration formed around the protrusion. In the closed position, the protrusion of the flapper door engages the male/female configuration of both door and port mesh resulting in a metal-to-metal seal across the access port. The metal-to-metal seal provides enhanced resistance to mechanical, heat, and chemical wear encountered during surgical and sterilization operations.
摘要翻译：公开了一种套管针，其包括具有上端和下端的壳体组件和连接到壳体组件的下端以限定穿过其中的轴向孔的插管组件。所公开的套针还包括用于在孔中滑动接合的闭塞器。壳体组件包括形成在上端上的进入端口，其与套管针的孔轴向对准。通过壳体的进入口的通信由具有关闭位置和一定程度的打开位置的挡板阀调节。挡板阀包括具有围绕突起形成的阳/阴构造的金属挡板门。在关闭位置，挡板门的突起与门和端口网的阳/阴配置接合，从而在接入端口上形成金属对金属的密封。金属对金属密封件提供了增强的抗外科手术和灭菌操作中遇到的机械，热和化学磨损的能力。

摘要： An inhalator including an inhalator body including a powder receiving chamber for receiving a powder, an air-powder mixture reservoir for temporarily storing an air-powder mixture flowing from the powder receiving chamber, and a diluent air passage for introducing a diluent air into the air-powder mixture reservoir. The air-powder mixture is formed within the powder receiving chamber when an air is introduced into the powder receiving chamber. The air-powder mixture within the air-powder mixture reservoir is admixed with a diluent air introduced thereinto through the diluent air passage. The diluted air-powder mixture is discharged from an air-powder mixture outlet into a user's oral or nasal cavity. A powder composition for inhalators includes at least two kinds of fine particles different in particle diameter.
摘要翻译：一种吸入器，包括：吸入器主体，包括用于接收粉末的粉末接收室;用于临时存储从粉末接收室流出的空气 - 粉末混合物的空气 - 粉末混合物储存器;以及用于将稀释空气引入空气的稀释空气通道粉末混合物储层。当空气被引入到粉末接收室中时，空气 - 粉末混合物形成在粉末接收室内。将空气 - 粉末混合物储存器内的空气 - 粉末混合物与通过稀释剂空气通道引入的稀释空气混合。稀释的空气 - 粉末混合物从空气 - 粉末混合物出口排出到用户的口腔或鼻腔中。用于吸入器的粉末组合物包括至少两种粒径不同的细颗粒。

摘要： A hemostatic device for sealing blood vessels, particularly for use in angioplasty comprises: (1) a barrel including: (a) a cylindrical portion; and (b) a terminal tapered portion, the terminal tapered portion being divided by at least one slot cut therein so that the tapered portion expands radially when force is applied to it; and (iii) an aperture at the narrow end of the terminal tapered portion; (b) a proteinaceous powder in the cylindrical portion of the barrel, the proteinaceous powder including at least one protein that promotes hemostasis in a blood vessel, the aperture in the terminal tapered portion being for flow of the proteinaceous powder; and (c) a plunger inserted into the barrel, the plunger including: (i) a narrow portion including therein means for guiding a guidewire; and (ii) a conical portion extending from the narrow portion so that, when the plunger is inserted into the barrel, the large end of the conical portion is located closest to the tapered portion of the barrel. The proteinaceous powder can be fibrin, thrombin, or fibrinogen. In use, the device is inserted into the tissue in the vicinity of an artery during the performance of angioplasty over a guidewire and leaves a plug in the tissue to seal the artery.
