Description
Technical field
The present invention relates to disposable use medical instruments field, be specifically related to a kind of control system for radial artery hemostat, a kind of radial artery hemostat and this control system of a kind of use and operate the method for this radial artery hemostat.
Background technology
Along with growth in the living standard, coronary heart disease has become the mankind's main killer gradually, and coronary artery intervention diagnosis and treatment operation have become one of Main Means of diagnosis of coronary heart disease and treatment.At present, femoral artery and radial artery are mainly divided in the intervention path of coronary artery intervention diagnosis and treatment operation.1989, the pioneering Experience of Transradial of Canadian doctor Campeau carried out coronarography; 1992, Dutch doctor Kiemenij reported the result that adopts this approach to treat.Along with coronary artery intervention diagnosis and treatment operation popularizing in the world, trans-radial carries out coronary artery intervention and has been widely used in clinical crown cardiopathia intervention diagnosis and treatment, and little with its damage, Local Complications is few, the advantage of perioperatively to anticoagulant, antiplatelet drug little, the postoperative tube drawing immediately of restriction and needn't force to lie in bed 24 hours etc. more " Wicresoft " and patient and get involved doctor's favor extremely.China is carried out coronary artery intervention diagnosis and is treated operation by radial artery path having exceeded 500,000 examples every year at present.In addition, trans-radial path row nerve and peripheral blood vessel diagnosis and treatment operation also receive increasing concern.
Because arteriotony is higher, after arterial intervention diagnosis and treatment operation, need to carry out the long-time object that reaches hemostasis of oppressing to radial artery puncture point.In clinical operation, mainly contain three classes for the hemostatic device of radial artery puncture point compressing at present.
The first kind is air sac hemostatic device, carrys out the normal pressure between augmented airbag and point of puncture by full air in air bag.
Equations of The Second Kind is rotary haemostat, increases the normal pressure between compressing piece and point of puncture by adjusting knob.Document US2009281565 provides a kind of radial artery to compress device.The defect that this radial artery compresses device technique is: 1, this invention adopts rotation pressure method, and force value can not be carried out the measurement of science, is not easy to find suitable force value; 2, manually pressure release, increases medical personnel's work.
The 3rd class is binder formula haemostat, by regulating the hemostasis by compression of wrist strap degree of tightness.Document US4760846A provides a kind of radial artery pincers.The defect of these radial artery pincers is: 1, adopt experience setting method, pressure cannot be measured, and is not easy to find most suitable pressure; 2, pressure manual adjustments, increases medical personnel's work.
This three classes device all adopts the method for manual adjustments apparatus to carry out qualitative adjustment pressure, belongs to experience Hemostasis, can not carry out quantitative setup pressure value according to different patient's radial artery blood pressures.If pressure is too small, can not reach the effect of hemostasis; If pressure is excessive, easily cause Radial artery occlusion, local skin and nerve injury.Investigation demonstration, in the coronary artery intervention diagnosis that trans-radial carries out at present and treatment operation, approximately 10%～15% patient there will be Radial artery occlusion symptom in various degree, has increased the risk of performing the operation.
Part Study person also by all means, attempts realizing radial artery hemostatic with electronic equipment.But electronic section cost is too high and be not easy to recycle shortage practicality.
In sum, although the mentality of designing of multiple radial artery hemostat is provided in prior art, still have the following disadvantages:
(1) force value can not quantitatively be set.Studies have shown that, if radial artery local hemostasis point pressure can be controlled to radial artery mean arterial pressure level, can effectively stop blooding and can reduce the generation of complication.And current radial artery hemostat is all to exert pressure according to doctor's experience, be difficult for setting most suitable pressure according to different patients.
(2) manually pressure release.Current radial artery hemostat in use, all relies on manual mode to realize pressure and regulates.Such mode has increased doctor and nurse's workload.
(3) recycling rate of waterused is low.Current radial artery hemostat is mostly disposable use, and repeat usage is low, wastes resource, has also increased patient's economic pressures.
(4) complicated disinfecting process.Even if some electronics radial artery hemostats can reuse, but can bring complicated disinfecting process, and the cost of sterilization is also higher.
Therefore, current radial artery hemostatic product also possesses larger room for improvement at the aspect such as automatization, informationization.
