Abstract: The present invention belongs to the medical field, and relates to novel ?-lactamase inhibitors, for the treatment of bacterial infections in combination with ?-lactam antibiotics, including infection caused by drug resistant organisms and especially multi-drug resistant organisms. The present invention includes compounds according to formula (I): or pharmaceutically acceptable salts thereof, wherein M and R are as defined herein.

Abstract: A device for defibrillation and monitoring, a monitoring component, and a component for defibrillation and monitoring, are disclosed. The device for defibrillation and monitoring includes a host and a monitoring apparatus, which are assembled and disassembled through a detachably connection. The host is capable of independently performing defibrillation operations and display defibrillation information at least. Therefore, when it is necessary to go out for defibrillation operation alone, only the host is carried to medical assistance facilities. This monitoring apparatus can independently implement monitoring functions. When it is necessary to go out for implementing separate monitoring operations, just the monitoring apparatus is carried to the medical assistance facilities. Therefore, the user flexibly selects the devices they carry according to their requirements, improving the convenience of use.

Abstract: A method for scheduling and displaying three-dimensional annotations is provided, relating to the field of realistic three-dimensional visualization technology. The present disclosure covers data services, data scheduling schemes, data storage schemes, annotation avoidance schemes, and annotation efficient display schemes. Users can use this disclosure to schedule and display massive three-dimensional annotations in WebGL at high frame rates while consuming extremely low performance. It solves the problem of text inversion and non-hierarchical zooming of three-dimensional maps in traditional annotation and slicing services which can cause text to appear larger or smaller, breaking through the technical bottleneck that traditional annotation and slicing services that cannot be superposition displayed on 3D models.

Abstract: An injection pump and an infusion pump are provided. Display areas of screen assemblies of the injection pump and the infusion pump extend from the left sides of the center lines of the front sides of pump doors to the right sides of the center lines. Widths of the display of the screen assemblies of screen assemblies are greater than the heights thereof. Or the widths of the screen assemblies of the screen assemblies are greater than or equal to 70% of the widths of the front sides of the pump doors. By using the modes above, the screen assembly may form a roughly elongate display area. At least part of the display area also possesses a touch function, so that some physical buttons used for inputting instructions can be omitted, ensuring that the display area is larger, presentation of more information is displayed, and viewing of users is facilitated.

Abstract: The present disclosure provides a logistics route prediction method and apparatus. The method includes: obtaining chain network information of a logistics chain network corresponding to a logistics unit, and determining a target analysis domain and confidence node(s) of the logistics unit according to the chain network information; determining fast node(s) according to the chain network information, the target analysis domain, and a timeliness level of each of the logistics nodes in the logistics chain network; and determining a predicted logistics route corresponding to the logistics unit according to the chain network information, the target analysis domain, and the confidence node(s). In which, the fast nodes at which the logistics unit passing through is determined first, thereby improving the prediction efficiency, and the confidence nodes are used as the basis for determining the predicted logistics route among multiple possible flow routes, thereby improving the reliability of the prediction.

Abstract: A medical device and a storage box for a medical article are provided, where the medical device at least includes a main case having at least two exposed chamber outer walls and an accommodation compartment for accommodating a medical article. The at least two exposed chamber outer walls enclose an accommodation chamber to accommodate a functional module. The accommodation compartment is disposed on the main case and adjacent to the accommodation chamber. The accommodation compartment includes at least one exposed compartment outer wall, and the at least one exposed compartment outer wall is connected to the at least one chamber outer wall of the main case. The medical device enables the medical article to be well accommodated in the accommodation compartment, and the accommodation compartment can be flexibly configured onto the medical device to decrease the space occupied by the accommodation compartment.

Abstract: This invention provides a method for preparing a polycarbosilane by decomposition and rearrangement a cyclic silane compound or chain polysilane under the catalysis of a boron-containing catalyst in a trace amount (less than 1 wt %). In the method, poly(dimethylsilane) (denoted as PDMS) or a thermal decomposition product thereof, i.e., a liquid silane-carbosilane compound (denoted as LPS), is used as the raw material, less than 1 wt % of the boron-containing catalyst (with respect to the amount of the raw material) is added, and then the temperature is gradually increased to the reaction temperature under atmospheric pressure or high pressure to perform the thermal decomposition/rearrangement reaction so as to obtain solid polycarbosilane (PCS) with a higher ceramic yield.

Abstract: A method and device for coating a medical device, such as a stent, including rolling the stent against a ribbon or gravure roll impregnated with coating material. The ribbon and gravure roll may include a recessed pattern matching a strut pattern of the stent. The stent may also be rolled against a plate or cylinder while coating material is forced onto the stent through a pattern of holes or openings in the plate or cylinder matching a strut pattern of the stent.

Abstract: A two-part tool for reading and adjusting an implantable valve, and methods of use. The tool includes a locator-indicator component that, when placed matingly on the patient's skin over the valve, provides magnetic reading of the valve setting. The tool also includes an adjustor component that couples to the locator-indicator component and is rotatable to change a valve setting.
