A blood access for dialysis includes a radially distensible support structure having an open lattice structure defining a support wall having interstitial open areas and defining exterior and luminal wall surfaces; a first porous polymeric portion having a plurality of pores, the first porous polymeric portion being securably disposed over at least a portion of the exterior wall portion of the support structure; a second porous polymeric portion having a plurality of pores, the second porous polymeric portion being securably disposed over at least a portion of the luminal portion of the support structure; and a biodegradable and / or bioabsorbable material disposed within the pores of the first polymeric portion and / or pores of the second polymeric portion.

A radar device has a transmitter having a field of view for transmitting a transmit signal and a receiver for receiving a received signal from the field of view of the transmitter. The transmit signal comprising first and second polarization components and multiple frequencies. There is a signal processor programmed to: detect received signal components comprising first and second polarization components and fundamental and harmonic frequencies corresponding to the first and second polarization components and multiple frequencies in the received signal; compare the received signal components to characterize the received signal and identify a remote device as a linear conductor or a non-linear conductor based on predetermined criteria; and generate a notification signal corresponding to the remote device when the remote device is identified.

A packaging system for improved management of cap inventory when different beverages, such as different types of milk (skim, 1%, 2% and whole) or water (spring, distilled, fortified, mineral etc.) are bottled in the same bottling lines at various facilities. The system includes maintaining a supply of standard caps, which may be free of colorants or pigments, and a supplies of reels of different colored (or differently printed) shrinkable band material. The different types of beverage are bottled in containers that have a single standard cap and standard uniform bottles, and the different contents of said bottles are differentiated from one another by the application of colored (or distinctively printed) bands. The cap and / or the bottle neck are adapted to be engaged by the band in a way that protects the bottle from being tampered with, and when threaded caps are used, helps prevent the inadvertent loosening of the caps during in shipment. In an alternative embodiment, a band is strapped over the top of the cap and is heat welded or otherwise adhered at both ends to the bottle neck, effectively restricting removal of the bottle cap without detaching at least one end of the band.

A multi-stage pump has a housing defining a plurality of stages each having an internal rotor enclosure with each enclosure having a non-pumping inlet and outlet. A plurality of rotor assemblies are operatably contained in housing extending through all of the stages. The rotor assemblies and rotor enclosures are shaped to provide a smaller inlet volumetric delivery rate at the last (downstream or outlet) stage than at the first (upstream or inlet) stage. A plurality of fluid lines connect the non-pumping chambers to enable the pump to handle liquid so that, as the rotor assemblies are rotated, a fluid stream entering the pump inlet is subjected to a pumping action to transport the fluid stream to exit through the pump outlet.

The invention discloses an electric film printing system based on DICOM, comprising an image device and an electric film printer, the image device is used for sending a shot electric film image to the electric film printer to print through a DICOM PRINT protocol, the electric film printer comprises an electric film printing server and at least a DICOM web camera, the electric film printing server is respectively connected the image device and the DICOM web camera. The invention also discloses an electric film management method based on DICOM, comprising the following steps: send a film image to the electric film printing server through the DICOMPRINT protocol by the image device; identify patient information from the film image by the server; store the file head and the image data body of the film image after the patient information is identified in the file system of the electric film printing server; when the patient needs to print the electric film, send the electric film to the DICOM web camera to print. Print on demand of the electric film is realized by the invention, thereby reducing the usage cost of the film and increasing the printing efficiency.

A heat exchanger and a manufacture method thereof are provided. Before a tank body and a core plate of a header tank of the heat exchanger are fastened to each other, a gel seal material or a liquid seal material is applied to at least one of a seal surface of the core plate and that of the tank body and hardened. Thus, a seal member which adheres to the seal surface due to the tackiness of the seal member is formed. The core plate and the tank body are fastened to each other in such a state that the part between the seal surface of the core plate and that of the tank body are sealed by the seal member having been hardened. Accordingly, the seal member can be restricted of twisting and position-deviating when the core plate and the tank body are fastened to each other.
