Description

Neurological hammer

The utility model relates to medicine, in particular to neurology, and relates to the construction of neurological hammers designed to study deep or propriceptive reflexes, surface or exteroceptive reflexes, their properties and degree of difference, as well as the surface sensitivity and functions of the cranial nerves.

The construction of a neurological hammer (KaWe Trömner neurological hammer) is known, which is a drummer, inside of which there is a needle with an external blunt and internal pointed tips, a replaceable double-sided hammer made of rubber, and also a handle at the end of which there is a brush with Frey bristles.

The closest in design to the claimed neurological hammer is the neurological hammer according to the patent [RU 2050831, 12/27/1995], which contains a drummer with a handle and is configured to accommodate a needle wheel, scapula, needle, brush with bristles Frey, a striker in the form of a cylindrical a rod made of rubber, under which a piezoelectric transducer interacting with the striker is placed. The piezoelectric transducer converts the mechanical force of the shock into electrical signals and transmits them to the electronic unit. The handle of the hammer is made in the form of a hollow cylinder, in which the electronic block of the digital code with the digital scoreboard and the block of the light indexing unit, containing the green, yellow, and red LEDs, are placed. In addition, a thermometer with a contact sensor, as well as an optical

one

system including a power source, incandescent lamp, color filters - green, blue, red. Color filters are a segment of a strip of thin flexible light-conducting material with rounded ends, having a hole at one end for attaching a slide moving up and down along a longitudinal groove made in the wall of the handle. In addition, the lower part of the handle contains a nut, inside of which a transparent glass lens is fixed, having a concave surface on the inside, and a switch button.

The main disadvantage of the above neurological hammer is that the device for determining the patient’s perception of the color gamut, or the optical system, is a rather complicated and unreliable design when using with color filters made of thin and flexible material associated with a slide moving in the longitudinal groove of the handle, the lower part of which contains a nut with a lens.

As a disadvantage of the neurological hammer described above, one can note the complexity of its design, caused by the saturation of various functional elements, some of which are not necessary for the practitioner. So, in the hammer there is a device for measuring the force of impact on the patient’s reflexogenic zones, including not only a piezoelectric transducer, but also an indication system, both digital and color. As a rule, when diagnosing, the force of impact in the indicated areas is determined by the weight of the falling projectile, and it should be constant. It depends on the experience and qualifications of the doctor. The presence of a device for measuring the force of impact, accompanied by a color indication, can be used more for the purposes of training a novice doctor, and not in the process of a real examination that requires stable force of impact. Accommodation

the needle wheel at one end of the drummer makes the hammer traumatic, especially when you consider that the doctor wears it, as a rule, in the side pocket of the robe.

Thus, the objective of the utility model, in relation to the main improvement regarding the device for determining the patient's perception of the color gamut (optical system), is to increase its operational reliability and simplify the design.

The essence of the utility model is that the proposed neurological hammer contains a drummer with a handle, and is configured to accommodate a needle wheel, a Frey brush, a needle and an optical system consisting of a light source with a lamp and filters connected through a switch to a battery. The drummer, on the side of each of its ends, contains coaxially made cavities, one of which is closed by a main striker made of an elastic material, made with the possibility of placing a light source and a fixed disk with filters of different colors, located behind an opaque screen made in in the form of a rotary disk with a through hole located coaxially with the light filters. The handle is made into two parts, the first of which (the holder) carries the hammer and is designed to accommodate a double-sided needle and conical tip with an obtuse angle, and the second is the handle itself, made with the possibility of placing a retractable rotary needle in the end groove at the end of the handle wheels mounted to move along the axis of the handle and the exit of the needles beyond it.

The second cavity of the striker is made with the possibility of placing an additional striker made of elastic material bearing on

the opposite end of the brush, both strikers have a detachable connection with the hammer, and the main striker consists of a work surface and base.

In the drawings attached to the description, are depicted:

- in FIG. 1 - Structural diagram of a neurological hammer;

- in FIG. 2 - Rechargeable lamp with a color selection system (increased);

- in FIG. 3 - Needle wheel in working position;

- in FIG. 4 - Axial section of the handle on the needle wheel. The neurological hammer (Fig. 1) includes a drummer 1, which

the sides of each of its ends, contains coaxially made cavities, one of which is closed by the main striker 2, having a shock part with a developed working surface 3 of elastic material, for example, porous rubber, and the base 4 of the striker made of hard rubber (polymer) with detachable connecting element 5 (Fig. 2). Under the removable main striker 2 are batteries 6 with a light source 7 that turns on the button 8. The light flux passes through the filters 9 mounted on the fixed disk 10. In front of the fixed disk 10 there is a rotary screen 11 in the form of a rotary disk with one through hole located coaxially with the filters . The handle is made with the possibility of a connector into two parts, the first of which is a holder 12 carrying a hammer 1 and is configured to accommodate a double-sided needle 13 with blunt and pointed tips. The second part of the handle is the handle 14 itself, inside of which, on the side of the holder 12, an additional conical tip 15 is mounted to study a number of physiological and pathological reflexes of the patient's hands and feet. The second cavity of the hammer 1 is arranged to accommodate an additional

the hammer 16 of elastic material connected to the hammer 1 by means of a collet 17 and carrying at the opposite end a brush 18 with Frey 19 bristles for studying tactile sensitivity. At the same time, both the main firing pin 2 and the additional firing pin 16 have a detachable connection with the hammer 1. The handle 14 is made with the possibility of placing at its end a rotary wheel 20 equipped with needles 21. The wheel 20 is retractable for the purpose of increase the comfort of use and eliminate the possible risk of injury to both the patient and the doctor. For this, the wheel 20 is mounted on the sliders 22 installed in the groove 23, which allows it to move along the axis of the handle 14 and thus exit the needles 21 beyond its limits.

A neurological hammer is used as follows.

To study the direct and reverse photoreactions, color perception, and external assessment of the organ of vision, the striker 2 is removed from the striker 1. Then, the light source 7 is turned on, by means of the button 8 and by turning the screen 11 its through hole with one of the filters of the fixed disk 10 is informed. deep reflexes, the drummer 1 lowers at low speed onto the reflexogenic zone with the main striker 2 and, due to the increased flat working surface 3 and the flexibility of its material (polymer), a deep reflex is achieved the patient has virtually no pain in the study area, not to mention the possibility of injury (hematoma, cracking of the bone or cartilage with a concomitant pathology of bone-mineral metabolism, etc.). In this case, due to the base of the striker 4, made of more rigid rubber (polymer) and the mass of the striker 1, acting indirectly on the reflexogenic zone, the degree of reliability of the called reflex does not deteriorate

compared to using a traditional stiffer striker. A removable needle 13 with a blunt and pointed tip located inside the holder 12 is used for local examination of sensitivity, surface reflexes, pathological synkinesias, etc. Small detachable firing pin 16 is used to study the reflexes of oral automatism. Small detachable firing pin 16 has a collet 17, which provides quick removal / installation of a small firing pin 16, at the opposite end of which there is a brush 18 with Frey 19 bristles, used to study tactile sensitivity. The movable wheel 20 located at the bottom of the ergonomically comfortable handle 14 with the needles 21 arranged along its circumference is lowered by means of the fixed sliders 22 from the upper edge of the groove 23 into the working position and is used to study the surface sensitivity of the patient, after which it is removed inside the groove 23 of the handle 14 and is fixed by the sliders 22 in a non-hazardous non-working position. In addition, to study foot pathological and physiological reflexes, the doctor can use an additional conical tip 15 (made blunter than the upper tip of the needle 13), holding the hammer by the hammer 1 and removing the removable handle 14.
