Description
Technical field
This utility model relates to medical instruments field, relates in particular to a kind of automatically device of control of air bag inlet and outlet that is widely used in.
Background technology
Department of obstetrics and gynecology are when delivering a child for the puerpera, in second stage of labor, the abdominal muscle and the diaphram that need the puerpera firmly to shrink oneself increase intra-abdominal pressure, thereby force the delivery of baby in the abdomen, abdominal pressure is the main power of fetus of giving birth to, and when puerpera self abdominal pressure deficiency, need to be by the help of external force.At present the normal way that adopts is that the practise midwifery personnel manually press puerpera's abdominal part with hands and increase abdominal pressure clinically, with this to puerpera's increasing coelica pressure practise midwifery power.
The mode of above-mentioned Manual pressurizing, because its pressure size, pressure distribution, rhythmicity, harmony are wayward, undue force also can affect uterus blood circulation and strength of uterine contraction.Therefore, executing abdominal pressure with air bag in recent years, to add the method that belt replaces the practise midwifery personnel to press with hands more and more, and the many air bags of various forms of abdorminal pressure air sacs such as monosaccate emerge in an endless stream.Yet the existing air bag mode majority of exerting pressure is limited to the purpose that manually adds, reduces pressure and execute abdominal pressure to reach to the air bag inlet and outlet, and also there is certain inconvenience in it in control operation.
Engendered on the market that at present some execute the device of abdominal pressure automatically, it is more accurate with respect to the device of manually executing abdominal pressure, and sensitivity is safe and reliable.Yet existingly have following problem with the fully-automatic midwifery device of executing abdominal pressure automatically for the abdorminal pressure air sac inlet and outlet: (1) signal filtering is to utilize puerpera and the larger contact surface of air bag to uterine contraction, filters high-frequency signal and signal shaping with air bag itself.Because the puerpera breathes, if the signal that the interference factors such as cough and body action form, persistent period is short, the rate of rise is large, frequency change is large, and the signal that the distortion of puerpera's abdominal part forms during uterine contraction is stronger, longer duration, the rate of rise is more slow, frequency is more stable, utilize single-chip microcomputer to carry out Statistical self similarity by above-mentioned distinguishing characteristics, to distinguish interfering signal and uterine contraction signal, thereby calculate contraction power and the frequency in uterus, it can not go to disturb with methods such as Statistical self similarities in time domain preferably, therefore be difficult to correctly judge puerpera's uterine contraction and accurately detect current contraction strength, therefore can't accurately apply abdominal pressure according to puerpera's needs and ability to bear.(2) thus connecting electric Proportion valve with a single air pump executes abdominal pressure automatically to air bag inlet and outlet control.Therefore the mode of this series connection is unfavorable for the quick control of air bag inlet and outlet speed because air pump and electric Proportion valve have the restriction of pressure, flow, is unfavorable for realizing accurately the fast purpose of real-time decompression.(3) power supply and air pump use alternating current mostly, and the power safety performance is not done further processing, and there is certain potential safety hazard in medical use.(4) whole device can only be controlled air bag, can't make the analysis judgement to puerpera and fetus physiological situation.
