Description
Technical field
The invention belongs to gynaecological and obstetrical instrument technical field, more particularly to a kind of gynaecology's hemostatic bag.
Background technology
Postpartum haemorrhage is the most common complication of obstetrics, wherein because of postpartum uterine contractions fatigue or separation of placenta and bleeding accounts for
More than 80%, amount of bleeding is very big sometimes, jeopardizes puerpera's life security, for that purpose it is necessary to carry out drug therapy.When Hemostatics are invalid
When, generally use intrauterine packing gauze stops blooding, and this is a kind of very original and simple Hemostasis.Filling process takes phase
Work as length, and to the pain stimulation weight of puerpera, under non-narcotization patient more unbearably by, if moreover, Via vagina is clogged, can not
Avoid sliver contact vaginal wall and be contaminated sterile sliver, greatly increase uterine cavity infection risk.In addition, for medical condition
For poor different medical unit, for massive haemorrhage, it is necessary to it can rapidly stop blooding, the time transferred from one hospital to another can be won, in order to
Hemostasis is using water pocket come to oppress uterine hemostasis be more effective means.The existing easy leak of water pocket, it is impossible to persistently press comprehensively
Compel uterus, make uterus still bleeding, and puerperal cervix uteri relaxes, and intrauterine water pocket is easy to skid off, and causes hemostasis by compression to be lost

The reparation and regeneration of road epithelium, comparatively fast reach the purpose for curing vaginitis；Intelligent gynecological therapeutic equipment collection inspection of the present invention is with controlling
Treat in one, simple in construction, esy to use, safe and reliable, low manufacture cost.
The present invention is modified to the transmission function of the present invention, realized defeated by adding PID control in control device
Go out the quick tracking and change of pressure, so as to eliminate the steady-state error of the operating pressure of gynaecology's hemostatic bag, realize gynaecology
Adjusted with the actual working pressure of hemostatic bag steady, accurate, fast.It ensure that gynaecology with hemostatic bag at work to patient safety.
PID controller is used for the deviation e according to gynaecology with the pressure value y and default pressure value r of hemostatic bag reality output,
Calculate the controlled quentity controlled variable u of pressure, and adjust and control the actual pressure in gynaecology hemostatic bag accordingly, make actual pressure value y with
Default pressure value r is equal or levels off to equal.
Pressure sensor is used for the pressure value y for monitoring reality output in real time, and feeds back to PID controller.
The rational pid parameter of PID control chip offer (including rate mu-factor Kp, integral coefficient Ki, differential coefficient
Kd).Pid parameter can enter Mobile state adjustment according to the empirical parameter of reality, can also be dynamic with hemostatic bag process according to gynaecology
Step response enters Mobile state adjustment.
Below to doing an explanation using above-mentioned compress control method；
During hemostatic bag, the pressure value of reality output is gathered in real time using pressure sensor.
Assuming that in kth (k is positive integer) individual sampling instant, default air pressure value is r (k), and pressure sensor is adopted
The pressure collected is set to y (k), after the actual pressure value y (k) is fed back in control circuit, PID control chip calculate this
The pressure divergence e (k) at k moment：
E (k)=r (k)-y (k).
PID controller obtains rational pid parameter Kp, Ki and Kd according to e (k) values being calculated.
Meanwhile PID controller, according to the scope of e (k) values, reasonable selection starts ratio control (P controls), integration separation
PID control (PD control), proportional plus integral control (PI controls), derivative-precedence PID or the PID control with dead band：
(1) when e (k) values are very big, typically when hemostatic bag just works, controlled using P；
(2) as e (k) → 0, using the PID control with dead band, vibrations are introduced to avoid system frequent movement, now,
Hemostatic bag pressure enters dynamic stability working condition；
(3) when e (k) values are larger, using PD control, integral action is temporarily cancelled, again can be with to avoid excessive overshoot
System is set to have faster reaction；
(4) when e (k) values are smaller, controlled using PID control or PI, to ensure the control accuracy of system；
(5) when needing to adjust preset value r (k), using derivative-precedence PID, differential only is carried out to output quantity y (k)
Control, to avoid preset value caused system concussion when lifting, improve the dynamic characteristic of system.
For (3), (4) two kinds of situations, a threshold value can be preset to e (k) values.
In the case of (3), (4) two kinds, the controlled quentity controlled variable u (k) of air pressure is calculated according to the following formula：
Wherein, u0 is default air pressure value.
The controlled quentity controlled variable u (k) that air-pressure controlling system calculates according to PID controller, adjust actual pressure, make its with it is pre-
If pressure it is equal (i.e. e=0).
Pressure is constantly so gathered, and is simultaneously and dynamically adjusted, so that it may so that operating pressure all-the-time stable is pre-
The pressure value first set.
Using technical solutions according to the invention, or those skilled in the art's opening in technical solution of the present invention, give,
Similar technical scheme is designed, and reaches above-mentioned technique effect, is to fall into protection scope of the present invention.
