摘要:
A method for at least partially inserting a plug into a hole, said method comprising the steps of a) providing a at least one substrate with at least one hole wherein said at least one hole has a largest dimension of from 1 μm to 300 μm, b) providing a piece of material, wherein said piece of material has a larger dimension than said at least one hole, c) pressing said piece of material against the hole with a tool so that a plug is formed, wherein at least a part of said piece of material is pressed into said hole, d) removing the tool from the piece of material. There is further disclosed a plugged hole manufactured with the method. One advantage of an embodiment is that an industrially available wire bonding technology can be used to seal various cavities. The existing wire bonding technology makes the plugging fast and cheap.
摘要:
A high-sensitivity analyzer for nitric oxide in exhaled breath at levels of 200 ppb or less with a sensor containing cytochrome C is rendered capable of multiple uses without the need for installing a new sensor for each use. This capability is achieved by regenerating the analyzer after each use by purging the sensor and surrounding regions with NOx-free air in a controlled manner, preferably in pulses separated by equilibration periods.
摘要:
A handheld, small but accurate and reliable device for diagnostic NO measurements using a NO sensor, where the parameters governing the taking of the sample are different from the parameters optimal for the accuracy of said NO sensor I described. By temporarily storing a portion of the exhaled air, and feeding this to the sensor at a flow rate adapted to the NO sensor, the accuracy and sensitivity of a system/method involving NO sensors, in particular electrochemical NO sensors, can be increased. The method for diagnostic NO measurements comprises steps for controlling the inhalation of NO free air, as well as the exhalation, both by built-in means and by audible and/or visual feedback to the patient.
摘要:
It has surprisingly been found that nasal NO release is greatly increased by the presence of a an oscillating airflow in healthy subjects. Accordingly, a device comprising means for generating and/or maintaining an oscillating airflow is described and suggested for use in the diagnosis of a condition of the upper airways of a human. The invention also encompasses method wherein the concentration and/or flow of at least one gaseous component in nasally exhaled air is determined and recorded in the presence and absence of an oscillating airflow acting on the upper airways or parts thereof.
摘要:
A scrubber for eliminating NO from air flowing through the scrubber, comprising a housing (1) having at least one inlet hole (2) and an outlet hole (4) and which is comprising filtering material (6). A second outlet hole (9) is provided in the housing (1) at a position situated at a distance from the first outlet hole (4) and any inlet hole (2) so that the air leaving the second outlet hole (9) will have flown at least through a depth of the filtering material (6) substantially corresponding to the depth of the filtering material (6) for the air flowing from the inlet hole (2) to the first outlet hole (4).
摘要:
Device and method for collecting endogenous gaseous nitric oxide (NO), in the urogenital tract, for example in the urinary tract and in the uterus and oviducts. According to one embodiment, a NO permeable, liquid impermeable inflatable body (16) is positioned in the urethra (5) surrounded by the prostate gland (17), whereby an additional inflatable body (4) positioned in the bladder (2) serves to seal off the bladder from the urethra and helps in the positioning of the device. The present invention further relates to a method and a system for use in the diagnosis of inflammatory states in said organs.
