Disclosed herein is a method of producing high purity pentagalloyl glucose (PGG), analogues or derivatives thereof, at least 99.9% pure, by washing with dimethyl ether. PGG may be provided in a kit, including a hydrolyzer for dissolving the PGG and a saline solution. Also disclosed herein is a device for delivery of a therapeutic solution to a blood vessel. The device may be a catheter having an upstream balloon and a downstream balloon. The upstream balloon may be expanded to anchor the catheter and occlude antegrade blood flow. The downstream balloon may be expanded to occlude retrograde blood flow, creating a sealed volume within the blood vessel. The downstream balloon may have pores configured to deliver a therapeutic inflation solution into the sealed volume or a portion thereof. The downstream balloon may be expanded by the expansion of a balloon disposed inside the downstream balloon.

A noise reduction structure for a ventilation treatment device and the ventilation treatment device are provided. The noise reduction structure comprises a first micropore plate; the first micropore plate has a first plate surface and a second plate surface which are opposite to each other, the first plate surface is used for forming a first chamber; the second plate surface is used for forming an air passage such that air in the air passage flows along the second plate surface; the first micropore plate has a plurality of first micro-vias through which the first chamber communicates with the air passage. The noise reduction structure is wide in noise reduction frequency band, may effectively reduce aerodynamic noise in the air passage, and improves the satisfaction degree of a patient using the ventilation treatment device.

Disclosed is a respiratory interface device (1) and components thereof. The respiratory interface device (1) comprises a body (2), a frame (3), and an inlet conduit (4).

The body (2) forms a chamber with the support platform (11) and comprises at least one nasal outlet (5), a base opening (7), and at least one further opening (6), through which the support platform (11) extends. The inlet conduit (4) comprises a connector (18) that clamps the body (2) and the support platform (11) together.

A device for irrigation of an oral cavity in a patient includes a suction element configured to be disposed in the oral cavity and configured to suction a fluid out of the oral cavity. The suction element also has one or more irrigation outlets configured to irrigate the oral cavity with the fluid. A suction line is fluidly coupled with the suction element and is configured to be fluidly coupled with a vacuum source. An irrigation line is fluidly coupled with the one or more irrigation outlets and is fluidly coupled with a source of the fluid.

Systems and methods for multi-chambered syringes are described. In some embodiments, a multi-chamber syringe includes a housing with an internal cavity and first and second plungers disposed at least partially within the internal cavity. The first and second plungers are slidably displaceable relative to the housing, and are associated with first and second chambers respectively. A barrier is disposed at least partially between the first and second plungers to form the first and second chambers. The barrier is slidably displaceable relative to the plungers and barrel to selectively place the first and second chambers including first and second materials respectively in fluid communication. When the barrier is displaced, the first and second materials mix in a combined volume of the first and second chambers. Displacing the first plunger, the second plunger, and the barrier may dispense the mixed materials from the combined volume.

A security tag can prohibit unauthorized usage of a device or product. The device may include an electronic nicotine delivery systems (“ENDS”) device, which may include aerosol delivery devices such as smoking articles that produce aerosol. The security tag can prevent usage until authorized. Attempts at usage without authorization can result in the device being unusable. The authorization may include identity confirmation or age verification.

The invention relates to a blood treatment device for carrying out an extracorporeal blood treatment in which blood is guided in a blood guidance device having a main blood line and at least one secondary line, the latter being fluidically connected to the main blood line and the main blood line having a dialyzer and, downstream from the dialyzer, a blood treatment element, wherein the blood treatment device has a control device; and a pump configuration, which is equipped for generating blood flows in the main blood line and also in the at least one secondary line, wherein the control device is designed to operate the pump configuration in such a way that a first blood flow rate in the dialyzer is decoupled from a second blood flow rate in the blood treatment element. Furthermore, the invention relates to a blood guidance device for cooperation with the blood treatment device as well as for a blood treatment system.

One aspect of the invention relates to an intubation aid (10). The intubation aid (10) comprises an elongated main part (12), and the intubation aid (10) is provided with an operating device (26). The main part (12) is designed to be curved in a first region (18) of the main part (12), and the main part (12) is additionally designed to be curved in a second region (20) of the main part (12), said second region being separated from the first region (18) and being arranged adjacently to the free end (16) of the main part (12). The main part (12) additionally comprises a positioning device (24) which is designed to limit a translational displacement of a tube (46) placed on the intubation aid (10) in at least one direction. A second aspect of the invention relates to an intubation aid which can be placed on an endoscope.

Methods of altering the surface energy of components of a mesh nebulizer are provided, comprising: a) depositing a metal surface layer on surfaces of the component; b) forming a hydrophobic coating layer comprising an organo-silicon or a self-assembled monolayer of an organophosphorus acid directly on the metal surface layer or indirectly on the metal surface layer through an intermediate organometallic coating; and either: i) removing select areas of the hydrophobic coating layer to expose the metal surface layer; or ii) forming a polymeric coating layer chemically bonded to and propagated from terminal functional groups on the hydrophobic coating layer that are capable of initiating polymer growth when exposed to a source of polymerizable monomer, on select areas of the components. Mesh nebulizers formed by such methods are also provided.
