Adamhaling-opnemerAdamhaling sensor
De uitvinding betreft êen apparaat, dat de verandering in omtrek van de borst en de buik, tijdens de ademhaling, 5 meet, hetgeen korreleert met de ademfrekwentie en amplitude.The invention relates to an apparatus which measures the change in circumference of the chest and abdomen during breathing, which correlates with the respiration frequency and amplitude.
Bestaande opnemers meten o, a. de temperatuursverandering van de luchtstroom d.m.v. een temperatuursgevoelige weerstand in de neus aangebracht, of het luchtvolume dat de mond of de 10 neus in-en uitgaat. Ze geven geen afzonderlijke informatie over de borst- of de buikademhaling, noch over de relatie tussen deze twee vormen van ademhaling. Meting van de ademhaling d.m.v. temperatuursverandering van de luchtstroom heeft bovendien als een artefact de toename van de kern-15 temperatuur van het lichaam bij inspanning, en variaties in de omgevingstemperatuur.Existing sensors measure, among other things, the temperature change of the air flow by means of a temperature-sensitive resistor placed in the nose, or the volume of air entering and exiting the mouth or nose. They do not provide separate information about chest or abdominal breathing, nor the relationship between these two forms of breathing. Measurement of respiration by In addition, temperature change of the airflow has as an artifact the increase in the core temperature of the body during exercise, and variations in the ambient temperature.
Ben andere methode zoals beschreven door Brokr *74 waarbij eveneens de variatie in de omtrek van de borst en de buik als maat voor de ademhaling werd geregistreerd, was 20 met een siliconenslangetje gevuld met kwik. Deze methode had als nadelen dat vrij regelmatig vervanging van het kwik en de elektroden aan de uiteinden van de kwikkolom nootzakelijk was door oxidatie van het kwik en reaktie met de elektroden. Daarnaast was er een zekere niet-lineariteit en een hysterese 25 effekt, tengevolge van de rek en inkrimping van het slangetje.Another method as described by Brokr * 74, which also recorded the variation in the circumference of the chest and abdomen as a measure of respiration, was with a silicone tube filled with mercury. The drawbacks of this method were that fairly frequent replacement of the mercury and the electrodes at the ends of the mercury column was beneficial through oxidation of the mercury and reaction with the electrodes. In addition, there was some non-linearity and hysteresis effect due to the stretch and contraction of the tubing.
Dan is er verder nog een methode,-die de weerstandsverandering van de huid, t.g.v. de uitrekking van de huid bij inademer^ meet. Nadelen hiervan zijn allereerst die, welke inherent zijn aan het gebruik van huidelektroden, zoals het 30 verlopen van de overgangsweerstand tussen elektrode en de huid, en ten tweede, de variaties die optreden t.g.v. zweet-sekretie en variaties in kamertemperatuur*Then there is a further method, which measures the change in the resistance of the skin, as a result of the stretching of the skin when inhaled. Disadvantages of this are first of all those inherent in the use of skin electrodes, such as the passage of the transition resistance between the electrode and the skin, and secondly, the variations that occur as a result of sweat secretion and variations in room temperature *
Het doel van de uitvinding is, een meer stabiele en meer 35 reproduceerbare meting van borst en buik ademhaling afzonderlijk, te verkrijgen, welke niet beïnvloed wordt door genoemde faktoren, en daarnaast veilig en niet onprettig is voor de patient of proefpersoon* 40 Dit werd bereikt door de volgende konstruktie. Zie tekening.The object of the invention is to obtain a more stable and more reproducible measurement of chest and abdominal breathing separately, which is not influenced by said factors, and in addition is safe and not unpleasant for the patient or subject * 40 This has been achieved by the following construction. See drawing.

KonstruktiebeschrijvingConstruction description
De opnemer bestaat uit een niet-rekbare, instelbare band (15), van b.v. katoen, om de borst, iets onder de beide tepels of mammae, of om de buik, plm.3 cm onder de navel, •5 die aan de voorzijde onderbroken is door een stuk soepel rekbaar elastieke band van plm. 20 cm. (13)The sensor consists of a non-stretchable, adjustable strap (15), e.g. cotton, around the breast, slightly under both nipples or breast, or around the belly, approx. 3 cm below the navel, • 5 which is interrupted at the front by a piece of supple elastic elastic band of approx. 20 cm. (13)
De beide uiteinden van de niet-rekbare band (15), en dus ook van de elastische band (13), wijken uiteen bij inademing en komen dichter bij elkaar bij uitademing.Both ends of the non-stretch band (15), and thus also of the elastic band (13), diverge on inhalation and come closer together on exhalation.
10 Aan beide uiteinden is nu een nylon koortje(7a,b) bevestigd. Beide koortjes gaan een doosje (10), dat midden op de elastische band is bevestigd, en dus midden op de borst of buik staat, binnen, elk aan een kant, door een gaatje in het doosje, waarin een glijringetje zit vastgeklonken (9a,b).' 15 Bik koortje loopt nu in het doosje over een afzonderlijk snaarwielsegment. Koortje 7a. loopt over segment 4b. en zit bevestigd aan haakje 17. Koortje 7b. loopt over segment 4a. en zit bevestigd aan haakje 16.10 A nylon cord (7a, b) is now attached to both ends. Both cords enter a box (10), which is mounted in the middle of the elastic band, and thus stands in the middle of the chest or abdomen, each on one side, through a hole in the box, in which a sliding ring is fixed (9a, b). " 15 Bik choir now runs in the box over a separate belt wheel segment. Choir 7a. runs over segment 4b. and is attached to hook 17. Choir 7b. runs over segment 4a. and is attached to hook 16.
Segment 4a. zit met de punt vastgesoldeerd (s) aan de draai-20 as van de potentiometer (1), en roteert door het spannen van X· het koortje 7b, rechtsom. Het segment wordt teruggetrokken door het veertje 6a,. dat bevestigd is tussen haakje 11,op het segment, en haakje 18 aan de wand van het 'doosje.Segment 4a. sits with the tip soldered (s) on the rotary axis of the potentiometer (1), and rotates the chord 7b clockwise by tightening X ·. The segment is withdrawn by the spring 6a. which is attached between hook 11 on the segment and hook 18 on the wall of the box.
25 De met. name belangrijke bijzonderheid van de uitvinding is de volgende. De lineaire potentiometer (1) is in plaats van gefixeerd, zoals gebruikelijk is, in deze konstruktie vrij roteerbaar opgesteld in zijn bevestigingsmoer (2), welke'^ vastgesoldeerd is aan het chassis (3). Dit chassis zit vast 30 aan het doosje. Door deze uitzonderlijke konstruktie is ook het huis van de potentiometer roteerbaar ten opzichte van het doosje. Aan dit huis van de potentiometer zit nu het andere segment (4b) gesoldeerd, waarover koortje 7a. loopt. Dit segment wordt teruggehouden met veertje 6b, dat bevestigd 35 is tussen haakje 12, en haakje 19.25 The with. Particularly important feature of the invention is the following. The linear potentiometer (1), instead of being fixed, as is customary, is freely rotatable in this construction in its mounting nut (2), which is soldered to the chassis (3). This chassis is attached to the box. Due to this exceptional construction, the potentiometer housing is also rotatable relative to the box. The other segment (4b) is now soldered to this housing of the potentiometer, over which ripple 7a. runs. This segment is held back with spring 6b, which is attached 35 between bracket 12 and bracket 19.
Door deze konstruktie wordt het mogelijk de verandering van de omtrek van de linkerzijde'en de rechterzijde van de borst of buik op te tellen, waardoor schok- en schuife'ffekt-40 en van de band t.g.v. wrijving met de huid en de kleding, 79 0 8 2 0 6 4 - 3 - vrij gering zijn., en niet in de registratie waarneembaar.This construction makes it possible to add the change in the circumference of the left and right sides of the chest or abdomen, resulting in shock and shear effects 40 and of the belt due to friction with the skin and clothing. 0 8 2 0 6 4 - 3 - are quite minor., And not noticeable in the registration.
Het doosje zal ook niet verschuiven als de ademamplitude van de ene flank groter is dan van de andere.Also, the box will not shift if the breathing amplitude of one flank is greater than the other.
5 Het doosje van de opnemer wordt midden op de borst, ter hoogte van het os xyphoideus, of op de buik iets onder de navel geplaatst. De band (15) wordt om de patient heen gevoerd, en vastgezet met klem 16, zodanig, dat bij diepe inademing de markeringskraaltjes (8a,b), die aan de nylon 10 koortjes zijn bevestigd, juist iets van het doosje afzitten.5 The sensor box is placed in the middle of the chest, at the level of the ox xyphoid, or on the abdomen slightly below the navel. The strap (15) is passed around the patient and secured with clamp 16 such that, upon deep inhalation, the marker beads (8a, b) attached to the nylon cords are slightly off the box.
Op de niet-rekbare band is eventueel nog een schaalverdeling aan te brengen, die een maat is voor de gemiddelde borst- of buikomvang van de patient of proefpersoon.If necessary, a scale can be applied to the non-stretchable belt, which is a measure of the average breast or abdominal circumference of the patient or subject.
