摘要:
L'invention se rapporte à un masque anesthésique pour enfants. Le masque comporte une paroi élastique (20) conçue de façon à entourer hermétiquement la région faciale de l'enfant se situant autour du nez et de la bouche. Une pièce de succion en forme de tétine (26) fait corps avec une partie (24) de la paroi (20) située au-dessous de l'ouverture transversale du masque destinée au passage du gaz.
摘要:
The present invention relates to a system, respectively a method for measuring the concentration of a substance in a solution or dispersion thereof, whereby the substance consists of a compound which is non-electrically conducting or very slightly conducting. The invention is primarily intended to be used for measuring the concentration of compounds or substances of medical interest, for example urea concentration in blood of a patient during for example hemodialysis, hemofiltration or hemodiafiltration. The conversion of the compound hereby occurs with a help of urease.
摘要:
An auto transfusion system for the collection, treatment and return of a patient's blood, comprising means for performing the respective steps, for example, a suction device (1) for drawing up blood and, where present, any rinsing fluids from an operation site or similar, a source (2) of anticoagulant, a source (2) of diluent, a collection vessel (3) for the to-be-treated blood, a filter (5) for the removal of a filtrate comprising a quantity of the diluent, and a storage vessel (8) for the treated blood. The system according to the invention is primarily characterized in that the said sources consist of a common storage vessel (2) for a mixture of anticoagulants and diluents. The system can further comprise a measuring device (9) for measuring the haematocrit- and/or Hb value of the treated blood.
摘要:
Suction device, preferably intended for auto transfusion and including means for supplying diluent and/or anticoagulant for mixing with drawn up blood within the suction device. The suction device is characterized by an integral valve arrangement with the help of which the mixing ratio can be varied.
摘要:
A dialysis system comprising means (41,41,43,44) for the conducting of dialysis liquid and blood respectively on either side of one or more membranes in a dialyser (37), means (61) for controlling one or more parameters of the dialysis liquid before the dialyser (37) and means (60) for measuring at least one parameter of the dialysis liquid after the dialyser (37). The dialysis system described is characterized by means for a comparison of the parameter measured after the dialyser with the set value of the corresponding parameter before the dialyser. The values measured may be used for the calculation of a blood parameter, which is altered as a function of the parameter measured, for the purpose of calculation and/or control of this blood parameter.
摘要:
An arrangement for the diffusion and/or filtration of substances between two fluids, comprising a stack of supporting plates (4) with membranes (5) arranged in between, contained in an outer enclosure (1) consisting of two enclosure parts (2,3) joined together to form a seal, the two enclosure parts (2,3) being held together by a retaining band (8) cast in situ. The invention is characterized in that the band (8) is so arranged within scores or channels (9-12), communicating with one another and contained in respective enclosure parts, that any possibility of the casting pressure acting in the direction of the stack is reduced or wholly eliminated. The arrangement in accordance with the invention is intended primarily to be used in connection with dialysis, haemodiafiltration, haemofiltration or similar extracorporeal procedures for the treatment of blood.
