Description

Electric therapeutic equipment for fracture

This utility model is a kind of electronic medical apparatus and instruments that is mainly used in set a broken bone, fixing, treatment behind the location that is specially adapted to fracture and rehabilitation.

The traditional remedies of fracture be after bone reduction being made as the master, must be fixing for a long time, cause local blood circulation to lower, metabolism descends, ankylosis, even cause phenomenon such as amyotrophy, these all are unfavorable for the healing of fracturing.Fixation of fractures and functional exercise are combined together, quiet, moving in conjunction with the desirable armarium that promotes union of fracture, be in the bone healing to be looked forward to always.

The purpose of the present utility model is in order to improve the defective of existing fracture electric therapeutic equipment, design a kind of scientific and reasonable, practical and convenient, the orthopaedics therapy apparatus that clinical efficacy is good, it is painful that patient with bone fracture is reduced, healing as early as possible, well-being.

Electrical heating splice in the present utility model (or claiming electric hot plate) can be heated for the fracture limbs, promotes local blood circulation.Electric vibrator produces the mechanicalness vibration, make the vibration of fracture site machine meat tissue persistence, reaches the local organization relative motion, and purpose promotes local metabolic.Because muscular tissue continues vibration, reduced neural not slightly the threshold of pain, good detumescence is arranged, analgesic effect.

Eccentric block in the motor oscillating device connects the another side of motor, press close to flexible, slick transmission diaphragm are installed on the eccentric block, the change vibrator is fixed on the axis direction on the electric hot plate, makes the transmission diaphragm, place on the electric hot plate, electric vibrator can be implemented massaging action to the patient.Like this, the electronic fracture therapeutic equipment mode that not only can vibrate or massage is treated diseases such as fracture; Can also treat diseases such as muscle fatigue, soft tissue injury, arthritis, or be used for aspects such as rehabilitation, health care.

The operation principle of electronic fracture therapeutic equipment is seen Figure of description 1.It is to be made of control circuit part (fine line institute frame part among the figure) electric hot plate part (fine dotted line frame H) and vibrator part (fine dotted line frame P).The connection mode that the design's instrument adopts as shown in Figure 1.The appliance component of selecting for use can select structure to arrive from the market.

When using civilian alternating current power supply, voltage becomes 2 * 16.5V by 220V, and power supply heating clamping plate and diode rectification are used.The power supply that the electrical heating clamping plate use exchanges safe voltage as 33V, the Circuits System of regulating and controlling temperature, and the Circuits System of timing automatic control electric vibrator is the 12V unidirectional current.The power supply that micromotor in the electric vibrator adopts is the 9V unidirectional current.The debugging of the automatic control circuit by electronic fracture therapeutic equipment, the steady temperature of electric hot plate can be according to the requirement of patient treatment, automatically be controlled on 4 temperature class commonly used such as 35,37,39,41 ℃, also can the arbitrary temperature value of debugging control in 35-41 ℃ of interval on.The running speed of electric vibrator is controlled by potentiometer, and the frequency during vibration is 15-41HZ, and amplitude is 0.13-0.18mm.The every work 40-50 of vibrator minute, ended 10-20 minute, continue circulation operation automatically.Adopt the shape that changes eccentric block in the vibrator, size or quality also can make the patient obtain the satisfied vibration or the dynamics of massage.

In the outlying district or the family of not powering as yet, can directly use the dc source of 36V.Electric appliance circuits figure can be referring to Figure of description 1.

The structure of electric vibrator is seen accompanying drawing 2-3, and it is by motor 2, shell 1, and a silk 4, eccentric block 3 and fixed lug 5 are formed.Accompanying drawing 2,3,4,5 is a kind of form of the example and the masseur of vibrator, and it is by the eccentric block another side at the connection motor, and modes such as deposited or bonding are installed a flexibility, slick leather transmission diaphragm 6 is formed to tie up to be close to eccentric block.

For an electronic fracture therapeutic equipment, can prepare a vibration, the dual-purpose vibrator of massage, two utensils of also configurable vibrator and the single use of masseur.The transmission diaphragm that massage treatment is used is allowanced for bark beyond the leather goods, and woollen goods felt, silk linen-cotton, nylon chemical fibre product etc. all can be used.The structure of eccentric block and design size are seen accompanying drawing 4-5 in the vibrator, generally select for use metal material processing to make.

The electrical heating clamping plate play a part fix bone position, attemperation, sense vibration or massage in therapeutic process.The shape of electric hot plate can be according to the physiological need at patient treatment position, make suitable electrical heating clamping plate of different shape or clamping plate combination, and normally used have strip, lamellar and their combined splint.The winding mode of electric heating wire has the widely different formula of laying etc. of returning of reciprocal wound form and plane that brings out line by on the electrical heating clamping plate, sees accompanying drawing 14～15.

This utility model application object is compared with existing electronic fracture therapeutic equipment, has obviously expanded multiple use, and the damage automatic control is convenient, and the science health is without any side effects, safety durable, and range of application is wide.This electronic fracture therapeutic equipment is observed through clinical trial more than a year, proves tangible pain relieving, detumescence, promotes growth of spur; the effect of accelerating union of bone fracture; generally reflected by medical worker and patient's welcome patient, using this therapeutic instrument has comfort, is reluctant after the start to shut down.The case of two hospital clinical tests of comprehensive areas of Shenyang, statistical result show that the total effective rate that 73 routine fracture patients are treated is 86.4%, and obviously efficient 56.4% has shortened treatment time, does not have other side effect.
