Description
Technical field
It is controlled the utility model is related to a kind of computer and drives blood formula interval inflating pressure post-operation lower limbs thrombus system, belong to doctor
Treat training equipment technical field.
Background technology
Lower-limb deep veins thrombus is the postoperative common complication of lower limb.The conventional means of control thrombosis have drug at present
Control and physical interventions.The most commonly used is intermittent inflating pressure system, binding modes to be for physical interventions:Patient is postoperative under double
Limb ties up gas cell (single blister cavities is similar to the cuff of sphygomanometers), by the inflator pump timing in monolithic processor controlled host apparatus
Level pressure is deflated to airbag aeration, plays the role of similar massage, promotes lower limb blood circulation to prevent thrombosis to reach
Effect.But this intermittent inflating pressure system is simple physical interventions, does not meet biology blood flow principle.Reason
It is:Since Pneumatic compression device is single air bag, therefore entire air bag region is by same pressure simultaneously when inflating pressure effect
The inflating pressure of effect acts on, and does not have ladder pressure, without distance sequencing, does not meet venous blood flow dynamics biology rule
Rule.
It is understood that thrombosis is mainly in vein, and the reflux direction of venous blood is close by remote, i.e., from from toe
Flow direction foot, ankle, shank distal, shank middle-end, shank proximal end reach knee, and receive returning for each section blood flow in the process
Stream, finally imports big vein.Traditional intermittent inflating pressure system includes ankle to each path of blood backflow when pressurizeing
Portion pressurizes simultaneously compared with veinlet, the medium vein of mid calf, the larger vein in shank proximal end etc., and the equal indifference of pressure.If
The blowing pressure is smaller just to be will appear a large amount of venous blood while flowing back so that and there is " blood gushes " phenomenon in pressure rise in reflux veins,
Cause to transport blood scarce capacity in the reflux veins short time, instead so that section of vein blood backflow obstruction and the stasis of blood is stagnant in blood vessel
In.On the contrary, when the blowing pressure is larger, then will appear entire air pressure capsule pressurised zone and meanwhile be under pressure and cause in short-term compared with
Veinlet be pressurized simultaneously closure, venous blood have little time reflux and the stasis of blood is stagnant in blood vessel.So traditional intermittent inflating pressure system
System will play a role, and pressure size wants moderate, aeration speed will be uniformly.But because the requirement of venous return pressure size can be because not
It is same position, different personal and cannot unify and the bad reasons such as grasp of venous return speed so that traditional intermittent to fill
Gas compression system is unable to exact operations, it is caused to have certain limitation in clinical application.
