Claims (2)

чающие возможность травматизации стенок мочеточника концами пластин. Устройство работает следующим образом . Трубчатое основание 2 с помощью эластичной трубки 3 вт гиваетс  в катетер 1, увлека  за собой пластины 8 и 9, которые укладьгоаютс  ;внутри катетера 1. В таком состо нии устройство ввод т в просвет мочеточника с помощью катетеризационного цистоскопа. После введени  устройства /: в мочеточник подвижную часть устройства с помощью трубки 3 вьгоод т из катетера 1, как показано на чертеже. Пластины 8, 9 разгибаютс  и утолщени  1О касаютс  стенок мочеточника. При сокращении мочеточни ка происходит деформаци  упругих пластин 8 и 9, котора  передаетс  на консольную балку 6. Деформаци  консольной балки 6 измер етс  с помощью закрепленных на ней тензорезисторов 7. Электрический сигнал, пропорциональный измер емой сжимающей силе мочеточника, передаетс  от тензоре- зисторов 7 к измерительной аппаратуре по проводникам 4. Утолщени  10, расположенные . на концах упругих пластин 8 и 9, вь полн ютс  в виде полусфер так. что при вь т гивании трубчатой основы 2 в катетер 1 они образуют сферу, котора  закрывает отве{ стие на конце катетера. Такое устройство более удобно вводить в исследуемый opraw. Предлагаемое устройство может примен тьс  не только дл  измерени  сжимающей силы трубчатых мышечных органов, но и цл  измерени  вьшужденной перестальтики кровеносных сосудов, например артерий, без нежелательной обтурации. По результатам этих измерений можно судиТь зб эластичности этих органов, а значит диагностировать атересклероз и другие заболевани . Формула изобретени  1. Устройство дл  измерени  сократительной силы трубчатых органов человека, содержащее катетер, эластичную трубку с проводниками внутри катетера и с жестким трубчатым основанием на конце, внутри которого закреплена одним концом консольна  балка с тензорезисторами, отличающеес  тем, что, с целью повышени  чувствительности устройства к сократительной силе исследуемых органов, оно имеет две упругие пластины, одна из которых закреплена на свободном конце консольной балки, а друга  на жестком трубчатом основании эластичной трубки. those that may traumatize the walls of the ureter by the ends of the plates. The device works as follows. The tubular base 2 is pulled into the catheter 1 by means of an elastic tube 3, which carries the plates 8 and 9, which are placed inside the catheter 1. In this state, the device is inserted into the lumen of the ureter using a catheterization cystoscope. After insertion of the device /: into the ureter, the movable part of the device with the help of the tube 3 from the catheter 1, as shown in the drawing. Plates 8, 9 are unbendable and the thickenings 1O touch the walls of the ureter. With contraction of the ureter, the deformation of the elastic plates 8 and 9 occurs, which is transmitted to the cantilever beam 6. The deformation of the cantilever beam 6 is measured using resistance strain gages 7 fixed to it. An electrical signal proportional to the measured compressive force of the ureter is transmitted from the strain resistances 7 to measuring equipment on the conductors 4. Thickness 10, located. at the ends of the elastic plates 8 and 9, they are filled in the form of hemispheres as follows. that when the tubular base 2 is pulled into the catheter 1, they form a sphere that covers the response at the end of the catheter. Such a device is more convenient to enter into the opraw under study. The proposed device can be used not only to measure the compressive force of the tubular muscular organs, but also to measure the force-induced over-muscle of blood vessels, such as arteries, without undesirable obturation. According to the results of these measurements, it is possible to judge the elasticity of these organs, and thus to diagnose atherosclerosis and other diseases. Claim 1. Device for measuring the contractile force of human tubular organs, comprising a catheter, an elastic tube with conductors inside the catheter and a rigid tubular base at the end, inside which is fixed with one end a cantilever beam with resistance strain gages, characterized in that, in order to increase the sensitivity of the device to the contractile force of the studied organs, it has two elastic plates, one of which is fixed on the free end of the cantilever beam, and the other on the rigid tubular base of the elas egg tube. 2. Устройство по п. 1, отличаюеес  тем, что на свободных концах пругих пластин вьшолнены утолщени  в иде полусфер. Источники информации, прин тые во вниание при экспертизе: 1. Авдеева Д. К. и др.
