Abstract

Invention belongs to the domain of medicine. The described stomach acidomechanical sensor consists of an elastic cylinder, installed on a stomach probe with a two-channel tube, and an active pH electrode with semi-spherical surface made of antimony. A power cord, which runs from the pH electrode, is positioned in one of the stomach probe channels, through which manometric analysis is executed. The other stomach probe channel is designed to suck out the contents of stomach. The stomach acidomechanical sensor synchronically reads acidity and agility from the same point of the examined organ. Because of close contact between pH electrode and the mucous membrane of the organ, the contact artifacts of electric signal are reduced.

Description

Išradimas priklauso medicininei sričiai. Aprašomas skrandžio acidomechaninis daviklis, skirtas sinchroniškai ir iš tos pačios skrandžio vietos registruoti dvi pagrindines organo funkcijas: rūgštingumą (aciditetą) ir judrą (motoriką, motilitetą).The invention relates to the medical field. Describes a gastric acidomechanical transducer for the simultaneous recording of two main functions of the organ: acidity (motility) and motility (motility, motility) at the same location in the stomach.

Žinomas pH-metrinis zondas (K).£. Jlen. pH ΜβτριίΗ xe.nyjKa. JleHHHrpaą, MeąiiuHHa, 1987, 144 crp.) turėjo aktyvuosius pH-elektrodus, patalpintus ant skrandžio zondo vamzdelio. Vykstant organo susitraukimams su po to sekančia relaksacija, skrandžio gleivinė atšokdavo nuo nejudraus ant zondo vamzdelio esančio pH-elektrodo, nutrūkdavo jų kontaktas ir susidarydavo registruojamo pH signalo kontaktiniai artefaktai. Be to, zondas neturėjo atsiurbiamojo kanalo ir įrenginio, registruojančio skrandžio judrą toje pačioje vietoje, kur buvo pH-elektrodas.Known pH-metric probe (K). £. Jlen. pH ΜβτριίΗ xe.nyjKa. JleHHHrpaa, MeąiiuHHa, 1987, 144 crp.) Had active pH electrodes placed on a stomach probe tube. During organ contraction with subsequent relaxation, the gastric mucosa bounced off the immobilized pH electrode on the probe tube, interrupted their contact and formed contact artefacts of the recorded pH signal. In addition, the probe did not have a suction duct and a device for recording gastric motility at the same location as the pH electrode.

Sukurtame AMA-daviklyje aktyvusis pH-elektrodas yra įmontuotas į ovalo formos elastinio baliono sienelę. Balionas yra patalpintas ant skrandžio zondo vamzdelio distatinės dalies. Zondo vamzdelis yra dvikanalis. Zondo vamzdelio vienas kanalas skirtas atsiurbti turinį (orą ir skystį), esantį apie balioną. Talpinant pK-elektrodą ant baliono ir atsiurbiant tūrinį, apie balioną susidaro nepertraukiamas kontaktas tarp aktyvaus pH-elektrodo ir tiriamosios organo sienelės dalies.In the developed AMA transducer, the active pH electrode is incorporated into the oval wall of an elastic balloon. The balloon is placed on the distal portion of the gastric tube. The probe tube is dual-channel. One channel of the probe tube is designed to suck up the contents (air and liquid) around the cylinder. Placing the pK-electrode on the balloon and suctioning the volume creates a continuous contact between the active pH-electrode and the test organ wall around the balloon.

Kitas AMA-daviklio privalumas - galimybė iš tos pačios tiriamojo organo vietos sinchroniškai registruoti dvi skrandžio funkcijas: rūgštingumą ir judrą. AMA-daviklio principinė struktūra pavaizduota schemoje (1 Fig.):Another advantage of the AMA sensor is the ability to synchronize two gastric functions, acidity and motility, from the same site of the test organ. The principle structure of the AMA sensor is shown in the diagram (Fig. 1):

Ant skrandžio zondo vamzdelio (1) distalinės dalies yra patalpintas elastinis ovalo formos plonasienis balionas (2) 5-7ml tūrio. Skrandžio zondo vamzdelis (1) yra dvikanalis, o jo distaliniame gale yra olyvos formos antgalis (3) su keliomis angomis. Elastinio baliono (2) sienelėje yra įmontuotas aktyvusis pH-elektrodas (4), turintis pusiausferinį išorinį paviršių iš stibio. Baliono (2) viduje nuo aktyviojo pH-elektrodo (4) eina elektrinis laidas (5) pro vieną skrandžio zondo vamzdelio kanalą (6). Baliono (2) ertmė yra susijungusi su šiuo kanalu, kuris proksimaliniame zondo gale susisiekia su manometrine aparatūra (7). Elektrinis laidas (5) proksimaliame zondo gale praeina pro kanalo (6) sienelę ir susijungia su pH-metru (8). Be to, į pH-metrą (8) įeina antrasis elektrinis laidas (9) iš atraminio pH-elektrodo, pritvirtinto prie tiriamojo paciento odos. Kitas skrandžio zondo kanalas (10) yra skirtas atsiurbti skrandžio tūrinį. Manometrine aparatūra (7) ir pH-metras (8) per analogas kodas keitiklį (11) susijungia su kompiuteriu (12).On the distal part of the gastric probe tube (1) is placed an elastic oval thin-walled cylinder (2) of 5-7ml volume. The gastric probe tube (1) is dual-channel and has an olive-shaped nozzle (3) at its distal end with several openings. The wall of the elastic balloon (2) is fitted with an active pH electrode (4) having a balanced outer surface of antimony. Inside the cylinder (2), the active pH electrode (4) passes through an electrical conductor (5) through a single channel (6) of the gastric probe tube. The cavity of the cylinder (2) is connected to this channel, which communicates with the pressure gauge (7) at the proximal end of the probe. The electrical wire (5) at the proximal end of the probe passes through the wall of the channel (6) and connects to the pH meter (8). In addition, the pH meter (8) includes a second electrical wire (9) from a support pH electrode attached to the skin of the patient under test. Another stomach probe channel (10) is designed to pump gastric volume. The manometer (7) and the pH meter (8) are connected to the computer (12) via an analogue code converter (11).

AMA-daviklio panaudojimo būdas. Skrandžio zondas su AMA-davikliu (vienu ar keliais) ištepamas glicerinu, iš baliono atsiurbiamas oras ir zondas įvedamas į skrandį. Per atsiurbiamąjį kanalą iš skrandžio yra pašalinamas turinys, kurį galima laboratoriškai ištirti. Balionas pripildomas puse savo tūrio oru, prie tiriamojo odos pritvirtinamas atraminis pH-eiektrodas ir zondas sujungiamas su matuojama aparatūra: pH-metru ir manometru. Registruojamų signalų konversija, kompiuterinis matematinis apdorojimas ir rezultatų spausdinimas vykdomas žinomais būdais ir metodais.Application of AMA sensor. The stomach probe, with one or more AMA transducers, is lubricated with glycerin, air is drawn from the cylinder, and the probe is introduced into the stomach. Through the suction duct, the contents are removed from the stomach and can be tested laboratory. The cylinder is filled with half its volume of air, a support pH electrode is attached to the skin of the subject and the probe is connected to the apparatus to be measured: pH meter and pressure gauge. The conversion of the recorded signals, the mathematical processing of the data and the printing of the results are carried out in known ways and methods.
