Description

Low-frequency electrotherapeutical instument for enuresis

This utility model belongs to a kind of medical electronic machine, especially for the treatment and the rehabilitation of enuresis sufferers.

Enuresis is commonly called as bed-wetting, all is more important commonly encountered diseases in department of pediatrics and urology department.Data at home and abroad is added up preschool child's sickness rate up to more than 10%, adult patients is arranged between also.This disease performance is obstinate, long patient and very big spirit of family members Dai Lai and the sensual misery of giving of the course of disease.Both at home and abroad this sick etiological study and diagnosis and treatment technology are all attached great importance to, but still do not had desirable measure in the treatment at present.The psychotherapy of reporting on the foreign literature, operation reconstruction, intravesical pressure training.Biofeedback control etc. mostly lacks curative effect, adopts the physiotherapy cure rate the highest less than 15%.Drug therapy once adopted strongly fragrant dose of anti-interference abroad, anticholinergic or intend sympathetic class medicine such as imipramine, DDAVP, ephedrine.Atropine etc. all have the different effect of paying of degree, and high curative rate 14% and effect are difficult to lastingly.

Consistently both at home and abroad at present think that the needle stimulus therapy is the most desirable, Ionescu acupuncture treatment 108 examples for example, cure rate 34.20%, institute of acupuncture and moxibustion, Shanghai and Shanghai institute of traditional Chinese medicine combined treatment 240 routine cure rates 31.2%.But difficulty is big on the acupuncture law technology, and the operation technique similarities and differences often have influence on therapeutic effect.And bring certain damage and misery to the patient, be difficult for obtaining especially child patient's cooperation of patient.

The purpose of this utility model provides a kind of not damaged, no pain, easy and simple to handle, and the special-purpose electrical medical apparatus that cure rate is high can be medical workers at different levels even patient oneself operation treatment easily.Basic design of the present utility model is to utilize the particular low frequency ripple to improve neural signal conduction block, thereby makes the patient can recover normal control ability to urinary system effectively, tackles the problem at its root.Design key of the present utility model is to have been filtered out by a large amount of medical practices the effective impulse parameter of particular low frequency ripple.Specifically at selected low frequency wave generator (B), it produces frequency is 1-15Hz, and pulse width is the pulse square wave of 0.3-0.6ms, or the intermittent pulse square wave.For guaranteeing medical effect, make patient's no pain simultaneously, square wave its crest voltage after regulating circuit output should be able to reach 100V, and its negative pulse voltage should not be higher than-10 volts.Ordinary circumstance should be regulated peak forward voltage at 60-100V, simultaneously oppositely between the negative pulse voltage maintenance-10V--20V.

Overall structure comprises four parts, power supply (A), and particular low frequency wave producer (B), adjusting output circuit (C) and moist electrode (P1, P2).According to different use occasions, power supply can be direct current, interchange, or alternating current-direct current hybrid power supply mode, can become multichannel output when output regulating circuitry is used in hospital and treat a plurality of patients simultaneously to adapt to.

How further specify the purpose of this utility model below in conjunction with accompanying drawing realizes.

Fig. 3 is an oscillogram

This electro-therapeutic apparatus is divided into four parts on the overall structure, power supply (A), particular low frequency wave producer (B), output voltage regulation circuit (C), moist electrode (P1, P2), according to different use occasions, power supply can be made direct current, exchange, alternating current-direct current also can be made multichannel output, to treat simultaneously a plurality of patients when being used for hospital.

The given particular low frequency square-wave generator of embodiment (Fig. 2) comprises the two large divisions, when K switch 3 is placed the b position, the self-excitation transformer manifold type oscillating circuit of forming by BG2 work only, produce a low-frequency square-wave, by output terminal electrode (P1, P2) output comes, and its concrete waveform of its pulse width L1=0.3-0.6ms can be referring to Fig. 3 (f).(P1 P2) directly is placed on the acupuncture point that the patient selectes output voltage, selects suitable pulse width and output voltage amplitude can reach satisfied effect according to conditions of patients again by two moist electrodes.

Among the given embodiment of Fig. 2, given particular low frequency wave producer is made up of two parts independent circuits, so design mainly consider in the medical practice need be at different situations and in order further to consolidate medical effect.A part is by audion (BG2) and transformator (T) primary coil (L1, L2) self-excited oscillator of Zu Chenging, it can produce pulse width is the pulse square wave (Fig. 3 (f)) of 1-15Hz for the 0.3-0.6ms frequency, its frequency parameter is regulated by potentiometer W4 and the C3 capacity is selected, this agitator is used for can receiving satisfied effect for normal children's patient treatment by pulse square wave of transformator secondary side coil (L3) output when waver K3 places the b position.

Needs of patients to some state of an illness stubbornness is repeatedly treated, in order to overcome the continuous impulse square wave is produced adaptability, in square-wave generator, also designed modulation generating circuit (B1), it is by an integrated circuit (555) and resistance R 1, R2 potentiometer W1, W2 capacitor C 1, C2, diode 2CP overlap joint forms and can produce the rectangular wave of a pulse width for the about 1:1 of 0.1-1.3s dutycycle, but adjusting the W1 pulse-width regulates, the effect of W2 is to regulate dutycycle, and thereby the adjusting square wave (d) of generation be added in by audion BG1 makes on the base stage of BG2 and produces the secondary side coil output of a step pulse square wave (e) by transformator (T).The effect of potentiometer (W3) is the frequency of regulating self-excited oscillator, and batch (-type) pulse square wave and continuous square pulse fit applications can make to be brought up to more than 90% the effective percentage of patient treatment.

Be output voltage regulation circuit in the empty frame (C) in the embodiment circuit, it is by secondary side coil (L3) and the resistance R 7 of transformator (T), potentiometer W5, W6 forms a partial pressure type circuit, there are two taps to select strong and weak output on the secondary side coil by K switch 2, cooperate the W5 coarse adjustment, the W6 fine tuning can realize that the output voltage peak value is adjustable in 60-100V, guarantee simultaneously negative pulse be controlled at-10--20V between.(P1 P2) exports patient's selected treatment acupuncture point to pulse voltage, makes patient's not damaged, and no pain also plays significant curative effect by moist electrode.

Utilize this utility model treatment patient 100 examples, cure rate reaches 52%, and rate 16% closely more, inefficiency only 4% is a kind of special-purpose electrical medical apparatus of promotional value that has.
