摘要:
A device and a method for spraying a certain quantity of fluid. The device includes a casing with a cavity for accommodating a liquid reservoir and a pump which delivers a specific quantity fluid upon activation. The device further includes a nozzle through which the flow of fluid passes in the form of spray droplets together with an activating device which acts upon the base of the reservoir due to the application of opposing forces to the casing, basically at right angles to the pumping movement of the device.

The present invention relates to a pump chamber (1) for a pump intended primarily for infusion systems for medical use, said pump chamber comprising walls (21, 28) delimiting said chamber and an inlet (22) and an outlet (23), a part of said walls of said pump chamber being formed by a flexible membrane (40, 90), said membrane being actuatable by a reciprocally movable actuating means (80), thus varying the volume of the pump chamber in accordance with the movements of said actuating means. The membrane (40, 90) has a convex domed shape projecting outwardly from said pump chamber (1) and is made of a resiliently flexible material, the apex of the domed membrane being acted upon by said actuating means, said actuating means having a stroke which may be adjusted to the amount of the dose to be administered. The invention also relates to a valve for a pump chamber.

A implant assembly (1) includes a frame structure (10) with an inwardly protruding support flange (16), a first frame portion (12) extending above the flange (16) and a second frame portion (14) extending below the flange (16). A first semipermeable membrane (20) is positioned on a first side of the flange (16) and a second membrane (30) is positioned on a second opposite flange side. A first seal (2) is formed at the first frame portion (12) and a second seal (3) is formed at the second frame portion (14) to form an enclosed inner chamber (18) defined by the membranes (20, 30) and the frame structure (10).
摘要:
A device for discharging cream or paste like material from a container, comprising a treat-like sleeve of a resilient material which has a mechanism for securing on an outlet on the container. The sleeve is intended for being provided in a depending position on the container. Inside the sleeve in the upper portion a body is provided, which is designed to be forced towards the container in case of an increase of pressure in the cream or paste-like material in the sleeve, and which is, via an elongated member, connected with the valve member at the lower end of the sleeve, the valve member cooperating with a discharge opening at the lower end of the sleeve. The body is dimensioned to be guided by the container outlet or another opening connected to the latter. A passage is provided through the body with an outlet opening inside the sleeve. A check valve is provided inside or near the channel or the passage. In a preferred embodiment the channel or passage is provided centrally in the body and cooperates with a channel or passage in the elongated member, and the outlet is then provided in a side wall of the elongated member.

Device for registration of temperature over an area by means of thermochromatic materials, which includes one, two or several layers (1, 3) with thermochromatical material, and one or several surrounding heat storing plastic layers (4, 6) that extend the reading time with maintained heat picture. In the case with several thermochromatic layers these preferably are of different termocromatical materials reacting at different temperatures and so chosen and so arranged that the termocromatic materials together constitute a scale of temperature areas. By means of a template the colors in the termocromatic layers can be interpreted to temperatures or temperature intervals and be noted.
摘要:
A moisture-heat exchange arrangement which is intended for connection to a patient to humidify and heat the air inhaled by the patient, wherein the arrangement includes a moisture-heat exchanger unit (5) and a humidifier means (11, 12) that connects with the unit (5) to increase the humidity of the inhalation air. The humidifying means includes a casing (3) which is connected with the moisture-heat exchanger unit (5) and which has a first opening (9) that communicates with the moisture-heat exchanger unit and an opposing opening (6) that communicates with the patient. The inner surface of the casing has provided thereon a water-absorbing and/or water-vapour permeable material (11) which delivers moisture to the air inhaled by the patient.
摘要:
A device for dispensing a flowable substance, which includes a rigid open channel or basin-shaped first main part having a dispensing channel with a dispensing opening, and a basin- or channel-like second main part which is comprised of a resilient material and has a shape complementary to the first main part, wherein the first main part and the second main part are joined together to form a closed dispensing container, and wherein the second main part has an end wall that includes a closure part which is complementary to the dispensing channel of the first main part and which lies resiliently against the dispensing opening. Pressure applied to the upper part of the end wall causes it to pivot on pivot points causing the closure part to swing upwardly and open the dispensing opening to permit discharge of the substance.
摘要:
A spray device including a casing and a spray bottle. A closing element is arranged in a nozzle. The closing element substantially fills the nozzle in order to minimize residual amounts of a drug in the nozzle. The overall purpose is to protect the spray device from contamination and evaporation. A method for manufacturing with as few parts as possible a spray device that by usually manual action causes the spray bottle to effect a pumping movement which triggers a spray dose through the nozzle. The device is intended to increase dose accuracy and facilitate the actual pumping.
摘要:
The present invention relates to a spray mouthpiece arranged on the outer free end of a spray tube. The mouthpiece is adapted by means of intersecting flow passages to atomize liquid which is fed to the spray tube under pressure. The arrangement according to the invention comprises an elongated sleeve which is adapted to be carefully placed on the free end of the spray tube. The sleeve is designed with an end face on which is a centrally located mouthpiece opening. In the sleeve is a cylindrical body connecting to the end face. The body has grooves with which the sleeve forms at least two ducts communicating with the tube. From the tube end, the ducts run approximately axially up to the end face. By means of the intersecting flow passages formed on the end face of the body, the ducts are connected to a chamber that connects to the mouthpiece opening.
