Description

Устройства дл  измерени  и регистрации внутриполостного давлени , выполиенные в виде зонда с чувствительной головкой, известны.Devices for measuring and recording intracavitary pressure, made in the form of a probe with a sensitive head, are known.

В .предлагаемом устройстве, в отличие от известных, установлен малогабаритный датчик, преобразующий давление в электрический сигнал.In the proposed device, in contrast to the known ones, a small-sized sensor is installed that converts pressure into an electrical signal.

Така  конструкци  устройства удобна дл  его введени  в сосуд.This design of the device is convenient for its introduction into the vessel.

На фиг. 1 изображен корпус устройства в двух проекци х; на фиг. 2-рамка устройства.FIG. 1 shows the device case in two projections; in fig. 2-frame device.

Устройство состоит из корпуса /, рамки 2 и мем.браиы с тензодатчиком . Корпус 1 выполнен в виде головки 3 со штуцером 4. Рамка 2 представл ет собой пластинку с пр моугольным окном. Мембраной служит основа тензодатчика-.пленка из лака. Воспринимающим элементом тензодатчика  вл етс  тонюий слой висмута, нанесенного на пленку-мембрану испарением в вакууме.The device consists of a body /, frame 2 and a memory bar with a strain gauge. The housing 1 is designed as a head 3 with a fitting 4. The frame 2 is a plate with a rectangular window. The membrane is the basis of a strainer-film of lacquer. The sensing element of the strain gauge is a thin layer of bismuth deposited on the membrane film by evaporation in a vacuum.

Тензодатчик наклеиваетс  на рамку 2, а рамка приклеиваетс  к корпусу Л так что часть основы тензодатчика с воспринимающим элементом образует мембрану пр моугольной формы, соответствующей форме окна в рамке 2.The load cell is glued to frame 2, and the frame is glued to housing L so that a part of the load cell base with the sensing element forms a rectangular membrane corresponding to the shape of the window in frame 2.

На щтуцер 4 корпуса / навинчиваетс  полихлорвинилова  трубказонд , котора  служит дл  соединени  полости датчика с атмосферой рпри введении датчика в полость, в которой нужно измерить давление. В случае необходимости, через трубку в полость корпуса может быть подан калибровочный сигнал давлени . Через трубки выведены также провода от тензодатчика. Тензодатчик включен в одно из плеч моста Уитстона. Сигнал от моста с тензюдатчиком подаетс  на регистрирующий прибор, представл ющий собой тензометрический усилитель с самопищущим прибором на выходе. Корпус датчика используетс  как электрод дл  записи электрокардиогра.мм.A PVC pipe is screwed onto the housing 4 of the casing / screwed on, which serves to connect the sensor cavity with the atmosphere when the sensor is inserted into the cavity in which pressure is to be measured. If necessary, a pressure calibration signal can be fed through the tube into the body cavity. Through the tube also removed the wires from the load cell. The load cell is included in one of the shoulders of the Wheatstone bridge. The signal from the bridge with the strain gauge is fed to a recording device, which is a strain gauge amplifier with a self-searching device at the output. The sensor body is used as an electrode for recording electrocardiogram.
