Description

Therapeutic device for motion sickness

This utility model is a kind of electronic installation that is used for the treatment of motion sickness.

Dizzy sea, dizzy sky, carsickness, space sickness and other similar sick general designation motion sickness.This disease be since people by ship or during other vehicle, its motion jolts the human body vestibular nerve produced stimulates institute extremely.The trouble motion sickness has a strong impact on passenger's operate as normal and life, and the people is very painful.From the angle of military significance, serious motion sickness meeting obviously reduces the fighting capacity of army.The inventor once designed a kind of electronic vestibule-regulating device, though curative effect is preferably arranged for dizzy and motion sickness, but because this instrument acts on the human body vestibular nerve is a constant signal, thereby for the particularly heavy motion sickness weak curative effect of motion sickness, show to run in the above navigation of fresh gale that people can not control dizziness fully, feel sick, vomit.

The purpose of this utility model, design exactly and a kind ofly can be transformed into therapeutic apparatus opposite with the suffered direction that irritates in the refreshing footpath of vestibule, equal-sized alternating current to the motion vector of the vehicle of sensing such as hull, reach effective therapeutic effect, so that remove the misery of jolting and bringing, guarantee people's operate as normal and life to people by motion.

This utility model comprises three parts: 1, take advantage of and carry the movement of tool sensing state that jolts, 2, act on the pair of electrodes at mastoid process position behind the ear, 3, dc source.

The utility model will be further described below in conjunction with accompanying drawing:

The taking advantage of of this therapeutic equipment carried jolt sensing state and dc source of a movement of tool and is contained in the box. This box (1) is made up of lid and box body. Take advantage of and carry the movement of tool sensing state that jolts and formed by pendulum angle amplifier (I), alternating current generator (II). Pendulum angle amplifier (I) comprises gear train A, additional wheel (19), pendulum (17). If gear train is two-wheeled, its radius ratio is 9:1. Alternating current generator (II) comprises light source (13), two pairs of photosensitive tubes (14), arc support (15), potentiometer (20), double-pole single-throw (D.P.S.T.) power switch (6), two groups of output indicators (4) that light emitting diode forms. Wherein photosensitive tube all adopts the 3DU5C type, and potentiometer R is 47K Ω, and voltage meter is 10V, and dc source (22) is 3V, and dc source (21) is 9V or 25V. If this power supply is bought inconvenience, can be replaced by the electronic increasing apparatus.

Take advantage of and carry the movement of tool sensing state each several part connection of jolting and be: connect pendulum (17) on the wheel rim of gear wheel (16), intermesh with pinion (18) in its inboard, and engagement is very tight between two-wheeled, the coaxial installation additional wheel of pinion (18) (19), fill a light source (13) on this outside zero line of taking turns, this light source passes through K switch₂Be connected with dc source (22), form a closed circuit. Two pairs of photosensitive tubes (14) are connected with an arc support (15), and with the vertical range of light source (13) be 3cm, be equidistant simultaneously. With reference to Fig. 2, described two pairs of photosensitive tubes, wherein photosensitive tube LD₁Colelctor electrode and LD₃Colelctor electrode connect LD₁Emitter stage and LD₄Colelctor electrode connect LD₂Colelctor electrode and LD₃Emitter stage connect LD₂Emitter stage and LD₄Emitter stage connect. After these two pairs of photosensitive tubes that connect, voltage meter, the mutual parallel connection of potentiometer, pass through K switch₁Be connected LD with dc source (21)₁With LD₃Common colelctor electrode connect positive pole one end of power supply, LD₂With LD₄Common emitter stage connect negative pole one end of power supply. Two light emitting diodes of each group of output indicator are mutually in parallel and end to end, and the one end is connected with tie point a, the b of photosensitive tube respectively, and the other end is connected with electrode socket (7) respectively. Potentiometer (20) is turned round (5) with the output intensity accent and is connected. Scale on the gear wheel (2) expression hull vibration angle shows that by throw mouthful (2) show, the voltage on the voltage meter indication circuit shows that by intensity mouthful (3) show.

With reference to Fig. 4, adhesive type electrode (10) is made up of the lead (11) that adhesive cushion (27), an end plug head. Wherein adhesive cushion (27) is that to mould thin slice (26) compressed together by soft mould thin slice (24), tin platinum paper (25), middle with hole oval soft of ellipse, be filled with conductive paste in the hole, scribble adhesive sticker on the face of adhesive cushion, and attached subsides one plastic sheeting (28), tin platinum paper is connected with the lead (11) that an end is equipped with plug.

With reference to Fig. 2, Fig. 3, principle of the present utility model is illustrated: the swing of hull on left and right directions reaches induction installation when ship jolts.The gear wheel of gear train makes pinion do revolution around gear wheel because the effect of pendulum remains the vertical line position, but rotates with respect to the box shell thus, rotation simultaneously.Because the radius ratio of gear wheel and pinion is 9:1, so induction installation is accepted the variation of minute angle (2 °-5 °), will cause the rotation of pinion wide-angle, its pivot angle amplification is 1:9, plays the effect that pivot angle amplifies.Closed double-pole single-throw (D.P.S.T.) on and off switch, light source luminescent.Along with the swing of hull, light source is done swing with pinion, makes light source change to the exposure rate of photosensitive tube, causes its resistance to change, and excursion is at 4 kilo-ohms to hundreds of kilo-ohms, thereby has changed the size of electric current.Its resistance minimum when light source direct projection photosensitive tube, the electric current maximum.When light source oblique fire photosensitive tube, with the variation of illumination angle, its resistance increases gradually, and electric current diminishes gradually.When hull was put the equilbrium position, light source did not almost have effect to two pairs of photosensitive tubes, its resistance maximum, and electric current goes to zero.Produced alternating action just because of light source with the swing of hull, made at photosensitive tube LD to two pairs of photosensitive tubes ₁LD ₂During conducting, photosensitive tube LD ₃LD ₄End.On the contrary, at photosensitive tube LD ₃LD ₄During conducting, photosensitive tube LD ₁LD ₂End.Like this, 4 photosensitive tubes constitute variable electric bridge, thereby produce the alternating current that constantly changes the sense of current, size and have or not with hull vibration.Utilize conducting, the cut-off state of two groups of light emitting diodes of output indicator, this alternating current is shown.Simultaneously,, act on mastoid process position behind the human body ear, play and suppress or offset the effect of vestibular nerve, thereby the elimination patient's is dizzy because of irritated by the external world to produce excited or the variable signal that suppresses by this alternating current that the adhesive type electrode will produce.In addition,, regulate the power of output signal, produce better therapeutic effect by regulator potentiometer.

This utility model is used for the treatment of the particularly heavy motion sickness of motion sickness curative effect preferably.This instrument has that sensitivity is good, simple in structure, volume is little, operation and characteristics easy to carry, safe in utilization.Be convenient to go by ship and the person's of travelling on a plane use.
