Description
Technical field
The present invention relates to single use medical instruments field, be specifically related to a kind of radial artery hemostat.
Background technology
Along with the raising of living standards of the people, coronary heart disease has become the primary killers of the mankind gradually, and the operation of Percutantnoeus coronary intervention Diagnosis and Treat has 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 Percutantnoeus coronary intervention Diagnosis and Treat operation.1989, Canadian doctor Campeau initiated Experience of Transradial and carries out coronarography; 1992, Dutch doctor Kiemenij reported and adopts this approach to carry out the result for the treatment of.Along with Percutantnoeus coronary intervention Diagnosis and Treat operation popularizing in the world, trans-radial carries out Percutantnoeus coronary intervention and has been widely used in clinical crown cardiopathia intervention diagnosis and treatment, and little with its damage, Local Complications is few, perioperatively is to anticoagulant, antiplatelet drug little, the postoperative tube drawing immediately of restriction and need not force the more advantage of " Wicresoft " and the extremely patient and get involved the favor of doctor such as bed 24 hours.Current China carries out the operation of Percutantnoeus coronary intervention Diagnosis and Treat more than 500,000 examples by radial artery path every year.In addition, trans-radial path row nerve and the operation of peripheral blood vessel Diagnosis and Treat also receive increasing concern.
Because arteriotony is higher, arterial intervention Diagnosis and Treat Post operation, needs to carry out to radial artery puncture point the object that long-time compressing reaches hemostasis.In current clinical operation, the hemostatic device for radial artery puncture point compressing mainly contains three classes.
The first kind is air sac hemostatic device, carrys out the normal pressure between augmented airbag and point of puncture by air full in air bag.Document CN201768010U discloses a kind of radial artery hemostat, it comprises: adjusting rod, cushion, air bag, inner side fixing head, outside fixing head, fixing band, fixedly take back and wear thread gluing, inner side fixing head and outside fixing head are by fixing band and fixedly take back and wear thread gluing and be connected and fixed, wherein, adjusting rod is equiped with spring, air bag and cushion are connected to adjusting rod end successively, and be fixed on the fixing head of inner side by adjusting rod, air bag is connected with electron pressure pump block by pressure connection tube, and electron pressure pump is worn thread gluing fix by fixedly to be taken back.This radial artery hemostat is can Self-pressurizing agri hemostasis and self-timing, fixed point, the quantitative object reduced pressure by reaching the program setting of electron pressure pump.Air bag realizes electromechanical conversion by electron pressure pump, can alleviate the workload of clinical worker, after realizing trans-radial intervene operation, and the standardization of radial artery nursing.The defect of this radial artery hemostat is: 1, reusing is poor, can introduce complicated electronic equipment disinfecting process in practical operation; 2, complex structure, is not easy to observe wound.
Equations of The Second Kind is rotary haemostat, increases the normal pressure between compressing block and point of puncture by adjusting knob.Document US2009281565 provides a kind of radial artery hold down gag.The defect that this radial artery compresses device technique is: 1, this invention adopts and rotates pressure method, and force value can not carry out the measurement of science, is not easy to find suitable force value; 2, manual pressure release, increases the work of medical personnel.
3rd class is bandage type 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 this radial artery pincers is: 1, adopt experience setting method, pressure cannot measure, and is not easy to find most suitable pressure; 2, pressure manual adjustments, increases the work of medical personnel.
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 pressure.If pressure is too small, the effect of hemostasis can not be reached; If pressure is excessive, easily cause Radial artery occlusion, local skin and nerve injury.Investigation display, in the Percutantnoeus coronary intervention Diagnosis and Treat operation that current trans-radial carries out, the patient of about 10% ~ 15% there will be Radial artery occlusion symptom in various degree, adds the risk of operation.
Part researcher also by all means, is attempted using electronic equipment to realize radial artery hemostatic.But electronic section cost is too high and be not easy to recycle, lack practicality.This class device as described in document CN201120253679.7 (utility model patent publication number: CN202146329U).The document provides a kind of automatic program-controlled pressure quantitative-controlled hemostasis device, comprise tourniquet and air bag, also comprise air pump, electromagnetic valve, pressure transducer, take Single Chip Microcomputer (SCM) system as the control unit of core, air pump is connected with the air bag of tourniquet by pipeline, pressure transducer, electromagnetic valve are arranged on the pipeline between air pump and the air bag of tourniquet, pressure transducer is connected with the control unit signal of telecommunication, and three tunnels of control unit export audion Controlling solenoid valve, air pump and the alarm respectively by connecting.This automatic program-controlled pressure quantitative-controlled hemostasis device acts on the pressure of radial artery hemostatic point, has both overcome the deficiency that existing radial artery hemostat cannot quantize haemostatic pressure, can reduce pressure by automatic programme control again, reduce medical personnel's operation in hemostasis.But defect is: 1, this invention product repetition profit is not high; If 2 reuse, then can bring the complicated links such as sterilization, if single use, then involve great expense, poor practicability.
In sum, although provide the mentality of designing of multiple radial artery hemostat in prior art, still have the following disadvantages:
(1) force value can not quantitatively set.Research proves, if radial artery local hemostasis point pressure can be controlled in radial artery Mean Arterial voltage levels, effectively can stop blooding and can reduce the generation of complication.And current radial artery hemostat is all exert pressure according to the experience of doctor, not easily set most suitable pressure according to different patients.
