Description

one

The invention relates to the field of medicine, namely to the device for measuring muscle tone.

Known tonometers containing cor.nus, clock indicator, tnna with osioinone arrow, nodepress | IO of the case Io of the body glass ii at the bottom button

However, such tonometers are not obscure enough to take accurate measurements.

In order to fit-Nbn n specified deficiency nre, d, pagavmyG | The tonometer is equipped with an installed I, an irdicator with an additional driven arrow, O15 zannon ns means of a fricdnon with a roller, 5y, one wavelength H1) D | Ts, and an axial position in an axially equipped with a button, but in an initial position, but an axis, but with an axon bearing, equipped with a button, but in an initial position, but a lead, but an axis, equipped with a button, but in the starting position, but an axis. with a spring removing it from the engagement with the main arrow, and a latch interacting with the iodine; 11 | ru / cia cup and roller with a cushion needle.

Ma FIG. 1 shows the tonometer, side view, partial section; pa fng. 2 - the latch mechanism, the view of Sierre, di; in fig. 3 - the same, side view in a magnified scale; on f, ig. 4 shows an embodiment of a latch.

The tonometer contains an indicator / clock type on the sleeve 2, which carries the body 3, fastened with a screw 4. The button 7 is fixed on the indicator strip 5 by means of a threaded stud 6. . Coaxial with

About the case is installed a glass .9, iipeibMyoiecTvenno, transparent with a groove W node screw head 4; stack 9 is spring-loaded relation:: the case of the case is calibrated; //. On the outer surface of the case n the inner

10 the surface of the glass caused annular risks 12 and 13.

A stack of 14 pncats, resting on the distal ring 15 and fixed with a spring ring, is provided with a central

15 by a hole in which the sleeve / 6 is fixed, bearing a bolt / 7. In the sleeve 16 is mounted roller 18 with a button 19, zaklenlenn ring 20. The edge of the button 19 is provided with knurling IKO1. In the bore roller-knonka located

0 palik 21 with the head 22, carrying the arrow 23 with the leash 24, interacting with the arrow 25 of the indicator.

Between the ends of the button 19 and the sleeve 16 25 mounted spring 26, and between the ends of the roller 18 and the arrow 23 - spring 27; springs 26 and 27 are made mainly in the form of spring washers. The hole in the button 19 is closed by a lid 28. A window through which the hole passes is in the square / 7 lre30

the latch 29, the end of which enters the hole 30 in the edge of the glass 9. The latch 29 is provided with a ledge 31. interacting with the window of the square 17, and the limiter 32 n form a ring covering the latch; The knob of the latch is provided with a notch 33 for the finger.

The latch 29 can be placed iodine glass indicator and can be made in the form of a strap with an oblong hole for the passage of the roller 18, and the ledge 31 can be made interacting with the shoulder 34 of the roller 18 (see Fit. 4). The spring 35 is made spiral and the arrow 23 is connected with a roller 36 by a screw 37 and a spring 27. In the tonometer there is also an additional spring 38 for charging the latch; the end of the latter passes through the hole (not shown in the drawing) in the rim of the indicator and interacts with the glass 9.

The tonometer works as follows.

The end of the cup 9 is attached to the skin of the subject, while the cup 9 slides along the body 3, and the button 7 comes into contact with the skin and moves the indicator bar / and the arrow 25 associated with it, the latter leads through the leash 24 arrow 23. At the same time the cup 9 displaces the latch 29, the end of which rests against the bottom of the hole 30.

At the moment of combining treads 12 and 13, corresponding to the nominal pressure of the end face of the steel pipe 9 to the skin, step 31 leaves the window of the square 17, and the roller 18 with the button 19 is moved by the spring 26 in the sleeve 16 according to the drawing (in the embodiment of FIG. 4, the latch shoulder 31 extends out from under the shoulder 34, and the spring 35 retracts the roller 18 and the arrow 23 to the left), the lead 24 moves away from the arrow 25 of the indicator, and the arrow 23 is fixed in a position depending on the magnitude of the muscle being examined. The tonometer is retracted from the skin, while the cup 9 is retracted with the spring // to its original position, which allows for a sample to be produced under conditions convenient for the experiment, for example, to bring the device to a light source. Then, pressing the notch 33 of the latch head 29 to the right and

down, the latch is cocked, with this roller / (S is pressed to the right, and the leash 24 goes beyond the plane described by the indicator arrow 23. In the embodiment of Fig. 4, to retract the pad, just press the button 19,

This flange 34 moves to the right, and the ledge 31 of the latch extends under the collar due to the action of the spring 38. Then, rotating the roller / 6 by the button 19 against the clock hand, the lead 24 of the arrow 23 advances to the

the initial position of the arrow 25 indicator; The tonometer is ready for the next measurement. Roller 21 II spring 27 forms a friction connection between roller / 6 and arrow 23, excluding the possibility of breakage of arrows Irn

Turning the button 19 at the same large angle. In the embodiment of FIG. 4, the roller 21 is replaced with a screw 37 rigidly connected with the roller 18, relative to which the arrow 23 rotates freely, in this case the pointing of the arrow

provided by friction caused by pressing the arrow 23 by the spring 27 to the collar 34.

Prev 1 et and 3 about b ete n i

A tonometer comprising a housing, a dial gauge with a main hand, a cup springed relative to the body, and a spring-loaded measuring button, characterized in that, in order to increase

measurement accuracy; it is provided with an arrow installed in the indicator that is connected with a roller, which is axially movable in the axial direction and equipped with a rotation button, through a friction clutch.

to its original position, a leash with a spring leading the leash out of engagement with the main arrow, as well as a latch cooperating with a spring-loaded cup and a roller of the driven arrow.
