Ultrasonic drive unit can include control circuit, signal generating circuit, frequency selection circuit, power drive amplifying circuit, resonance impedance match circuit.Wherein, control circuit is connected with control unit, for according to from the signal behavior output of control unit, operating frequency, pulse/continuous ultrasound wave mode etc.；Signal generating circuit and frequency selection circuit collectively form oscillation drive circuit, and the signal that oscillation drive circuit produces is amplified by power amplification circuit after control circuit, then drive ultrasonic transducer 26 to send ultrasound wave through resonance impedance match circuit.Owing to ultrasonic drive unit can use known structure, therefore it is not described in detail at this；It will be clear that the concrete structure of each circuit in ultrasonic drive unit should ensure that ultrasonic transducer can work in above-mentioned parameter area.
Input block can be the device that keyboard, mouse, button, knob, touch screen etc. have human-computer interaction function, for selecting ultrasonic parameters (output, operating frequency, pulse/continuous ultrasound wave mode etc.) for user and controlling equipment.
Display unit can be the device that display screen (such as LCDs) etc. has display function, and it is used for showing ultrasonic parameters, equipment state, uterine contraction situation etc., in order to user understands status of equipment and rehabilitation situation.
Uterine contraction measuring unit is connected with control unit (wherein uterine contraction signal processing circuit may be provided in main frame) also by uterine contraction signal processing circuit, thus would indicate that the signal of uterine contraction situation shows on the display unit by control unit, for user reference.
Certainly, may also include the parts such as shell, fan, switch in main frame, owing to the concrete shape of main frame, structure etc. can use known technology, and it is not the emphasis of the present invention, therefore describes in detail the most one by one at this.
Preferably, the postpartum rehabilitation device of the present embodiment may also include that the electrical stimulation unit for puerpera carries out the electricity irritation involution of uterus；And/or for the gas-pressure massaging unit that puerpera is massaged.Electrical stimulation unit and gas-pressure massaging unit can use existing structure, and can be connected with main frame and being uniformly controlled of controlled unit.This electrical stimulation unit and gas-pressure massaging unit can carry out postpartum recovery by electricity irritation and massage auxiliary puerpera respectively, thus can comprehensively utilize different rehabilitation maneuvers, improve the rehabilitation efficacy of the postpartum rehabilitation device of the present embodiment further.
It is first turned on host switch when using the postpartum rehabilitation device of the present embodiment, control unit starts to initialize equipment, parameter needed for user is inputted by input equipment afterwards (includes the operating frequency of transducer, output power density, working method etc.), control unit sends ultrasound wave according to the state modulator ultrasonic launching head inputted, user determines position at the bottom of maternal uterine palace, and labelling body surface view field, ultrasonic coupling agent is repasted after view field's spraying ethanol, the sound passing membrane of ultrasonic launching head is fixed on view field, slightly firmly pressure ensures that it is combined closely with skin down, ultrasound wave is sent to uterine region；In use, pressure transducer continuous Real-time Feedback uterine contraction situation also shows on the display unit, and user adjusts parameter and rehabilitation scheme in real time according to this uterine contraction situation.After use completes, ultrasonic launching head can be closed, after getting ready continuation parameter current carry out on once use.
Rehabilitation test data
Randomly select 120 example puerperas as subjects, puerpera age is all between 21 to 40 years old, it is primipara, pregnant all 37 to 42 weeks, without pregnancy complication and complication, puerperal direct rooming-in, breast feeding, be randomly divided into ultrasonic group (81 example) and matched group (39 example) according to admission number.Matched group does not carry out recovering aid, complete clear-cutting forestland.The ultrasonic group of postpartum rehabilitation device using above-described embodiment 2 carries out ultrasonic rehabilitation, every day 1 time, each 30 minutes, totally 3 times (i.e. 3 days), wherein 41 examples use continuous ultrasonic, 40 examples use pulse ultrasonic waves, use middle according to uterine contraction situation and puerpera experience above-mentioned each in the range of adjust parameter in real time.The data of test gained are shown in Table 1.
The rehabilitation efficacy synopsis of the postpartum rehabilitation device of table 1 present invention
In table 1, palace is high also known as height of fundus, and unit be centimetre, its for phalanx associating upper limb to the distance at the bottom of palace, the front puerpera's empty bladder of measurement every time, and massage after uterus makes it shrink and use tape measuring again.Average palace High variation refers to that first day average palace height deducts the 3rd day high value in average palace, and its value the biggest expression uterine contraction degree is the biggest, and the involution of uterus is the best.
The VAS pain scores that VAS value is made for puerpera, wherein 0 point of expression is painless, and 3 points of following presentation have mild pain, and 4 ~ 6 points represent that pain is more serious but still can stand, and 7 ~ 10 points represent hurt like hell.Mean VAS scores change refers to that the Mean VAS scores of first day deducts the value of the Mean VAS scores gained of the 3rd day, and its value the biggest expression pain slows down the most obvious, and postpartum recovery effect is the best.
If postpartum vaginal bleeding time is more than 42 days, regarding as the involution of uterus bad, the involution of uterus bad number schedule of proportion illustrates that the bad puerpera's number of existing restoration of old ways accounts for the percentage ratio of whole puerpera's number.
Visible, in table 1, the palace High variation of ultrasonic group is significantly greater than matched group, and the bad ratio of the involution of uterus is then significantly lower than matched group, and this shows that the postpartum rehabilitation device of the present embodiment has significantly effect for the involution of uterus.
Meanwhile, in table 1, the VAS value of ultrasonic group changes also greater than matched group, and this shows that the postpartum rehabilitation device of the present embodiment also has certain effect for slowing down post-partum pain.
Simultaneously, the average palace High variation of ultrasonic group and matched group is carried out t inspection, result, represent that the P of data degree of correlation statistically is 0.001, this shows that data have the strongest statistical significance (generally using P < 0.05 as the standard with statistical significance), and the postpartum rehabilitation device of its gap strictly the present embodiment causes；And the bad ratio of the involution of uterus of ultrasonic group and matched group is carried out X 2 test, result, representing that the P of data degree of correlation statistically is 0.034, this shows that data have the strongest statistical significance, and the postpartum rehabilitation device of its gap strictly the present embodiment causes；Wherein, two above statistics all contrasts with matched group with ultrasonic group, and does not differentiates between continuous ultrasound and impulse ultrasound.
In a word, the postpartum rehabilitation device of the present embodiment has obvious effect for the postpartum recovery of women.
It is understood that the principle that is intended to be merely illustrative of the present of embodiment of above and the illustrative embodiments that uses, but the invention is not limited in this.For those skilled in the art, without departing from the spirit and substance in the present invention, can make various modification and improvement, these modification and improvement are also considered as protection scope of the present invention.
