An in-plane metal microneedle array and a manufacturing method therefor is disclosed. A large-size metal sheet is cut into small metal sheets. Inner sides of the upper and the lower cover plates of the tooling are provided with grooves matched with the sizes of the small metal sheets. Through holes are formed at edges around the cover plates. The metal sheets are placed in the grooves and fastened through bolts. The geometry and the size of a sheet microneedle array are designed, and a CAD model of the plane microneedles is built. A wire path is cut according to the CAD model. A few materials are reserved on both sides of substrates of the microneedle array without cutting. The unprocessed parts on both sides of the microneedle substrate are cut to obtain an in-plane metal microneedle array with a plurality of microneedle bodies.

A headgear for securing a mask to a user's face is described. The headgear requires a first load force to elongate the headgear and, when fitted to a user, applies a balanced fit force that substantially equals a load force applied to the headgear during respiratory therapy. In some embodiments, the headgear includes an elastic portion configured to provide a retraction force, a non-elastic portion configured to be inelastic in comparison to the elastic portion, and a restriction mechanism connected to the non-elastic portion and to the elastic portion. The restriction mechanism is configured to apply a first resistance force to the user's head on elongation of the headgear and a second resistance force to the user's head on retraction of the headgear.

A “clip-on” flow controller for IV lines automatically controls flow rate over a range of pressures through a self-contained valve and flow sensor. By eliminating a pump, a lightweight system with a long operating life can be produced, as well as a system that can be self-supported on the IV line yet still provide institutional-level flow accuracy without accurate elevation of the IV bag or careful monitoring.

The disclosure belongs to medical devices and particularly to soluble microneedle patches and small dose medical injection devices for transdermal injections of medical and cosmetic materials to patients. It also belongs to micro-electro-mechanical systems technology (MEMS). The materials can include vitamins, proteins, glycerides, vaccines, mono-, oligo- or polysaccharides, organic acids and its salts, as well as combinations of the said materials and their derivatives. The disclosed micro-needle patch can be used for medical purposes in hospitals, outpatient and home conditions.

A microrobot of which a drug release is controlled by a sound wave applied from outside, and a method of manufacturing the microrobot are disclosed. The method includes mixing and storing magnetic nanoparticles and a drug in a biodegradable resist, and forming a microrobot having a three-dimensional (3D) porous structure at the resist through two-photon polymerization (TPP). The microrobot is formed to control a release rate of the drug stored in the resist by a sound wave applied from the outside.

An aerosol delivery device may include a rechargeable power source configured to provide power to generate an aerosol, device electronics configured to generate the aerosol responsive to application of the power from the power source, and an authentication module. The authentication module may include a separate chip or circuit board relative to the device electronics. The authentication module may be inserted into the aerosol delivery device between the power source and the device electronics to control provision of the power to the device electronics for generation of the aerosol or between the power source and a charge port of the aerosol delivery device to control charging of the power source.

This disclosure relates to a medical device including, a hard part, a converter, and a conductive path. The hard part has fluid paths for guiding a medical fluid, in particular blood, through the hard part. The converter is arranged to measure a characteristic of the medical fluid while the fluid is present in one of the fluid paths. At least a first section of the converter or of the conductive path is applied to or superimposed on the hard part by a first additive application method. At least a second section of the converter or of the conductive path is applied to the hard part by a second application method. The first and the second additive application methods differ from each other.

Disclosed herein are rolled-membrane microfluidic diffusion devices and corresponding methods of manufacture. Also disclosed herein are three-dimensionally printed microfluidic devices and corresponding methods of manufacture. Optionally, the disclosed microfluidic devices can function as artificial lung devices.

The invention relates to a nozzle for use in a device for administering a liquid medical formulation, to a method for producing the nozzle in the form of a microfluidic component and to a tool for producing microstructures of the microfluidic component. The nozzle is formed by a plastics plate with groove-like microstructures which are covered by a plastics cover on the longitudinal side in a fixed manner. The production method includes a moulding process in which a moulding tool is used, which moulding tool has complementary metal microstructures which have been produced from a semiconductor material in an electrodeposition process by means of a master component.
