Description

 The invention relates to a device for measuring or recording for diagnostic purposes by retrieving information from the surface tissues of an organ or its parts and can be used in dentistry for depth probing of soft tissues (to a depth of 4-6 cm) when assessing the condition of periodontal and periodontal.

 A known sensor for determining the functional state of the oral mucosa, comprising a load tube, an elastic plate, a protective tube. The protective tube, the load tube and the elastic plate are coaxially mounted and cantilevered in the holder. A pusher with a support end is mounted on the working end of the elastic plate, which can be mounted in a hole made on the working end of the load tube, on which the support protrusion is located, around which the support ring is placed with a gap (autosw. N 1692543, class A 61 B 5/00, 1991).

 Known ophthalmic dynamometer containing a housing with a hole in which a rod with a tip, a spring and an indicator, a fixed and movable support, four strain gages, a second and third spring, a stop with a hole, coaxially mounted inside the housing coaxially with its hole, two stops fixed on the rod , the free end of which is made in the form of a support needle, a peak detector, the output of which is connected to the indicator, and an amplifier, the input of which is connected to the strain gauges, and the output with the input of the peak detector, a fixed support It is connected with the housing and through two strain gages with a movable support, a spring is located between the supports, the rod is located in the holes and fixed relative to the housing by springs located between the stops on the rod and the housing, and rests on the movable support, two strain gages are located on the fixed support, and the strain gages are connected by a compensation bridge circuit and the inputs of the amplifier are connected to the diagonal of the circuit (ed. St. N 1215660, class 61 B 5/02, 1984).

 A known sensor for determining the bioelectromagnetic reactivity index (BEMR) of soft tissues, containing a conical (or flat) tip, a sensing element, a weight nozzle, a connecting wire.

 The sensitive element is placed inside the rod (Bankov V.I. "Methodological manual for the use of pulsed complex modulated electromagnetic fields for treatment and diagnosis" Textbook - Yekaterinburg, Ural Medical Institute. 1992, p. 17, Fig. 2A and 2B prototype).

 The properties of a pulsed complex electromagnetic field (ISMEMP) were used to develop a method for diagnosing soft tissue pathology, based on the principle of measuring the spectral power density of the "response signal" of an organ interacting with the field, which allows obtaining information about the state of living tissue affected by a pathology close to clinical a picture of the disease.

 The known sensor is designed to collect information from the surfaces of tissues of an organ or its parts with a volume of not more than 1 cc, for example, from predetermined skin zones of Zakharyin-Ged or biologically active points (BAP).

 However, it is impossible to remove reliable information from the studied point of the oral cavity site with the known sensor, since the sensitive element of the sensor under the influence of the weight nozzle in different measurement points comes into contact with the tissue with uncontrolled force.

 An object of the invention is to increase the accuracy of determining the BEMR index of soft tissues by creating the ability to reliably equally affect the sensitive element on each studied point of the oral cavity.

 For this purpose, a longitudinal hole with a mark is made on the sensor housing, a rod with a tip (sensing element) is provided with a spring, which is rigidly fixed in the upper part of the housing and provided with a protrusion in the lower part for movement in the housing opening.

 To create the same effect of the sensing element on each test point, a rod with a tip is applied to the test point and when you click on the protrusion point of the spring, it is combined with the mark of the housing hole.

 The sensor is an element of the measuring oscillatory circuit of the diagnostic and treatment complex with a feedback channel "Malachite-010 P". Upon contact with the tissue site under investigation via the feedback channel, the spectral power density of the response signal is converted into the analog form recorded on the indicator of the complex as feedback voltage - IOS.

 Then, the Ios value indicator is translated into the BEMR index using a known standard graph. The values of the BEMR indices correspond to different levels of blood circulation and the structural and functional state of periodontal and periodontal tissues.

 The following notation is adopted in the drawing: body 1 with a hole 2 and a mark 3, a rod 4 with a tip 5, a spring 6, a protrusion 7.

 A rod 4 is inserted into the housing 1. The tip 5 of the rod 4 protrudes outward through a hole at the bottom of the housing 1. In the upper part of the housing 1, a longitudinal hole 2 is made. The lower part of the hole 2 has a mark 3 at a certain distance. The spring 6 is put on the rod 4. 6 is rigidly fixed to the upper part of the housing 1, the lower part of the spring 6 is provided with a protrusion 7, the protrusion 7 has the ability to move in the hole 2.

 The device operates as follows.

 To create the same effect on each investigated point with a sensitive element-tip 5, the rod 4 is applied to the studied point and the sensitive element-tip 5 of the rod 4 is pressed on the point until the protrusion 7 of the spring 6 coincides with the mark 3. When the tip 5 of the rod 4 is in contact with the studied tissue site (not shown in the drawing), the BEMP index response signal appears as a feedback voltage converted to an analog form on the complex indicator.

 Thus, the fixed pressure applied to the studied point of the oral cavity, allows to increase the accuracy of determining the BEMR index of soft tissues, as it is possible to equally act on the sensitive element on each studied point of the oral cavity. In addition, the design of the proposed sensor improves the usability of it and removes information about the state of the tissue from the "inconvenient" points of the oral cavity.
