Изобретение относитс к медицинской технике, в основном к устройству сфинктерометров , работающих на пневмоэлектрических элементах и предназначенных дл определени величины волевого тонуса, тонуса мышц в покое, а также момента пареза мышц при определении выбора метода лечени и оценки ближайших и отдаленных результатов лечени .The invention relates to medical technology, mainly to the device of sphincterometers, working on pneumoelectric elements, designed to determine the magnitude of volitional tone, muscle tone at rest, as well as the moment of muscle paresis when determining the choice of treatment method and assessing the immediate and remote results of treatment.

Известно устройство дл определени тонуса анального сфинктера, состо ш,ее из источника сжатого воздуха, блока измерени и регистрации давлени и воздуховода, который представл ет собой эластичную воронку . Это устройство не позвол ет точно определить величину волевого тонуса, тонуса мышц в покое, а также момент пареза мышц 1.A device for determining the tone of the anal sphincter, consisting of its source of compressed air, a unit for measuring and recording pressure, and a duct, which is an elastic funnel, is known. This device does not accurately determine the amount of volitional tone, muscle tone at rest, as well as the moment of muscle paresis 1.

Известен сфинктерометр, содержащий полый наконечник из эластичного материала , закрепленный на конце руко тки, котора имеет сквозной канал дл подачк сжатого воздуха, и блок регистрации 2.A sphincterometer is known, comprising a hollow tip of elastic material, fixed at the end of the handle, which has a through channel for compressed air intakes, and a recording unit 2.

К недостаткам известного сфинктерометра можно отнести сложность определени момента регистрации силы как наружного , так и внутреннего сфинктера.The disadvantages of the known sphincterometer include the difficulty of determining the moment of recording the force of both the external and internal sphincter.

Цель изобретени - упрощение определени момента регистрации силы сфинктера .The purpose of the invention is to simplify the determination of the moment of registration of the sphincter force.

Указанна цель достигаетс тем, что в полости упругого наконечника, соединенного с руко ткой, расположены контакты электроконтактного датчика, причем подвижной контакт выполнен в виде втулки с продольными прорез ми, котора одним концом жестко св зана с руко ткой и охватывает неподвижный контакт, бокова поверхность которого имеет гиперболическую форму.This goal is achieved by the fact that in the cavity of an elastic tip connected to the handle there are contacts of an electrocontact sensor, the movable contact being made in the form of a sleeve with longitudinal slots, which at one end is rigidly connected to the handle and encompasses a fixed contact, the side surface of which has a hyperbolic shape.

На чертеже представлен однн из вариантов конструкции сфинктерометра.The drawing shows one of the options for the design of the sphincterometer.

Сфинктерометр имеет руко тку 1 из электроизол ционного материала с каналом 2 дл сжатого воздуха. С руко ткой одним концом жестко св зан подвижный контакт 3, выполненный в виде втулки с продольными прорез ми, который охватывает неподвижный контакт 4. В неподвижном контакте имеютс продольный 5 и радиальные 6 каналы дл воздуха. Часть руко тки и контактную группу покрывает наконечник 7 из эластичного электроизол ционного материала. Контакты соединены с источником питани и средствами сигнализации электропроводом 8.The sphincterometer has a handle 1 of electrically insulating material with a channel 2 for compressed air. A moving contact 3, made in the form of a sleeve with longitudinal slits, which covers the fixed contact 4, is rigidly connected with the handle with one end. In the fixed contact there are longitudinal 5 and 6 radial air channels. The part of the handle and the contact group covers the tip 7 of elastic, electrically insulating material. The contacts are connected to a power source and signaling means by an electrical wire 8.

Сфинктерометр работает следующим образом.The sphincterometer works as follows.

Claims

When the sphincterometer is inserted into the rectum so that its tip above the contacts is covered by the sphincter, the sphincterometer is connected to the injection and recording device (not shown in the drawing). Reliable fixation of the sphincterometer is provided by the hyperbolic shape of the side surface of the non-iodine contact. In the initial position, the contacts will be closed. As the tip is filled with air in the system, the pressure will increase, and the tip volume will increase, and at the moment of incontinence of the sphincter the contacts open, as evidenced by the switching off of the light bulb. At this point, the system pressure is recorded. At the time of the onset of volitional contraction, the volume of the tip under the influence of the sphincter decreases, contacts close, as indicated by the electric light, and the force of the onset of volitional contraction is recorded, as well as. its maximum strength is both compression and volitional static holding. The use of the proposed sphypterometer to study the strength of the sphincter at rest, the volitional strength of the sphincter and the moment of paresis allows one device to conduct mass studies without sterilizing the device itself. Besides. All these parameters are determined with one procedure with a high degree of accuracy. The invention includes a sphincterometer comprising a hollow section of elastic material, closed at the end of a handle, having a through channel for supplying compressed air, and a recording unit, characterized in that, in order to simplify the determination of the moment of recording sphincter force, the recording unit is equipped with an electrical contact sensor, contacts which are located in the cavity of the tip, while the movable contact is made in the form of a sleeve with buttrodles, one end rigidly connected to the handle and covering a non-moving contact an act whose lateral surface has a hyperbolic 1 |) form.
