There is provided a method of making a fluidic system that comprises assembling a fluidic system comprising a first plate, a second plate and a membrane disposed between the first plate and the second plate; applying laser energy to the fluidic system to cause the first plate, the second plate and the membrane to melt at bonding areas; and allowing the bonding areas to cool down such that the first plate, the second plate and the membrane are bonded together.

The invention relates to a welding tool and to a method for pulse welding of plastic films for medical packs formed as bags. In general, the invention provides that the film material which is plastified during welding and thus free-flowing is specifically displaced into a deepened, edge-side inner region of the sealing surface by increasing the sealing surface area. The film material accumulated in the recess leads to an increase in the film thickness in the inner region (25i) of the weld seam (6, 7, 8). As a result, the mechanical stability of the medical pack formed as a bag can be improved.

The present invention provides an apparatus for producing and putting on gloves capable of producing gloves that fit an individual hand shape and also putting the glove on the hands, and a method for producing and putting on gloves. The apparatus for producing and putting on gloves comprises welding and cutting means which welds and cuts a first elastic film and a second elastic film at a position on the outer side of a contour of a user's hand in a state in which the user's hand is sandwiched between the first elastic film and the second elastic film.

Interfaces for positive pressure therapy having a mask assembly, a headgear assembly and a connection port assembly are disclosed herein. The connection port assembly has a ball joint connection with the mask assembly and includes a quick release button for easily disconnecting the gases source conduit from the mask assembly. The mask assembly may include a bias flow vent that is formed separately and attached to the mask assembly. The headgear assembly encircles the rear region of the user's head and may include at least some portions that are substantially non-stretchable.

A method of joining overlapping thermoplastic roofing membrane components in which a first thermoplastic roofing membrane component and a second roofing membrane component are positioned in overlapping relationship between a pair of complementary molding surfaces. Heat is generated in a metal substrate and transferred by thermal conduction from the metal substrate to overlapping portions of the first and second thermoplastic roofing membrane components to locally melt and coalesce a portion or more of the thermoplastic material of the first thermoplastic roofing membrane component and a portion or more of the thermoplastic material of the second thermoplastic roofing membrane component. The molten thermoplastic material of the first and second thermoplastic roofing membrane components forms a zone of coalesced thermoplastic material that, upon cooling, forms a solid weld joint.

A protective guard for a hand, finger or thumb includes a first thermoplastic layer heat welded to second thermoplastic layer. The second thermoplastic layer has a thickness that is greater than the thickness of the first thermoplastic layer.

The present invention relates to a device for making a pouch received in a wrapping, comprising a pouch making device which is adapted to produce a pouch containing brewable material in a water-permeable wrapping, and comprising a sealing station with two sealing jaws movable relative to each other for sealing the pouch in a wrapping formed by a wrapping material. This device is characterized in that it comprises a pouch handling device for removing the finished pouch from the pouch making device and a wrapping material handling device for handling the wrapping material during the U-shaped wrapping of the wrapping material, wherein the handling device and the wrapping material handling device are adapted such that the pouch held by the pouch handling device and the wrapping material held by the wrapping material handling device are introduced into the sealing station.

There are provided a synthetic resin joined body and a method of manufacturing the same, with which it is possible to secure both of sealing performance of a fluid passage and joint strength between synthetic resin parts, even if an area of a portion to be welded is reduced. The synthetic resin joined body includes: a baffle plate; an oil passage forming member which comes in contact with the baffle plate; an oil passage which is formed between the baffle plate and the oil passage forming member and through which lubricant flows; a sealing portion which is formed by welding the baffle plate and the oil passage forming member to each other on an outer side of the oil passage to seal a periphery of the oil passage; and a joint portion for joining the baffle plate and the oil passage forming member to each other.

The invention relates to a welding tool and a method for pulse welding films of plastic for medical packs formed as bags. The invention generally provides for the film material that has been plastified during welding, and is consequently free-flowing, to be specifically displaced by increasing the sealing surface area. The displaced film material can for instance compensate for dimensional and form tolerances. At the same time, however, the strength of the welded seam region, which adjoins the interior space of the bag, is not reduced.
