Description
Technical field
What the present invention relates to is a kind of medical apparatus and instruments, specifically a kind of at trans-radial interventional therapy postoperative to radial artery puncturing point hemostatic device.
Background technology
Radial artery is one of coronary angiography and the conventional approach of percutaneous coronary intervention (pci).The radial artery hemostat of clinical practice at present mainly contains three types: one type is the gasbag-type haemostat, increases pressure through increasing the airbag aeration amount; Another kind of is the rotary extrusion type spinning haemostat, through the direct Pressur hemostatic of adjusting knob; Last type is flat haemostat, through regulating the hemostasis by compression of wrist strap degree of tightness.Research confirms, if can radial artery local hemostasis point pressure be controlled at radial artery mean arterial pressure level (radial artery mean arterial pressure=diastolic pressure+1/3 pulse pressure difference), can effectively stop blooding and can reduce complication to take place.Existing haemostat pressure control can only rely on doctors experience; Hemostasis pressure is energy and accuracy controlling not; The pressure that often causes stopping blooding is excessive; Cause postoperative radial artery obturation, local skin and local complication such as nerve injury, tension force property blister and secondary infection to take place, prolong the hospital stays, increase hospitalization cost.
Summary of the invention
The object of the present invention is to provide a kind of pressure of using automatization's control pressurer system regulating and controlling effect in radial artery hemostasis point, reduce medical personnel's operation, reduce the automatic programmed pressure of operation risk and quantitatively control hemostasis device.
The objective of the invention is to realize like this:
Comprise air pump, electromagnetic valve, pressure transducer, be control core unit and alarm with the single-chip microcomputer; Air pump is connected with the air bag of tourniquet through pipeline; Pressure transducer, electromagnetic valve are arranged on the pipeline between the air bag of air pump and tourniquet; Pressure transducer is connected with the control unit signal of telecommunication, and three tunnel outputs of control unit are controlled electromagnetic valve, air pump and alarm respectively through the audion that connects.
The present invention can also comprise:
1, control unit also links to each other with liquid crystal display.
2, also comprise and measure the blood sheet metal, measure the blood sheet metal and be connected with the external interrupt mouth of single-chip microcomputer.
3, described pressure transducer is a silicon gauge pressure pressure transducer, connects the adjustable resistance that is used to return to zero on the silicon gauge pressure pressure transducer, and pressure transducer is connected with single-chip microcomputer through amplifying circuit.
4, the described blood sheet metal of measuring is two, and wherein one is connected with single-chip microcomputer external interrupt mouth and is connected to power supply through current-limiting resistance, and other one is connected to ground.
5, connect button for the control core unit through pull-up resistor with the single-chip microcomputer.
The present invention uses the pressure that automatization control pressurer system regulation and control hemostasis device acts on radial artery hemostasis point, has both overcome existing radial artery hemostat can't quantize the to stop blooding deficiency of pressure, again can automatic program control decompression in hemostasis, reduce medical personnel's operation.
The present invention couples together air pump, electromagnetic valve, pressure transducer through pipeline and air bag; With the STC12C5A60S2 single-chip microcomputer is the detection numerical value that its processing core obtains pressure transducer; System controls air pump automatically and electromagnetic valve work makes the pressure that acts on radial artery hemostasis point be controlled at the average radial artery pressure of patient value level, handles ideal hemostasis force value and the current force value that acts on radial artery hemostasis point that will set through single-chip microcomputer and shows at liquid crystal display screen.In program control decompression process, in case hemorrhage, two metallic conductors touch blood near the hemostasis point, make the input of single-chip microcomputer external interrupt, and single-chip microcomputer is controlled emergency pneumatic automatically, and gives the alarm.
Hemostasis device of the present invention can quantize regulating and controlling effect through automatization's control pressurer system and reach desired quantity in the force value of radial artery hemostasis point; Avoid existing haemostat only to exert pressure with doctors experience; Cause the radial artery blood flow to interrupt and thrombosis, reduce hemostasis related complication incidence rates such as radial artery obturation; In hemostasis, this hemostasis device can automatic program control decompression, reduces medical personnel's operation.In case it is hemorrhage; This device has emergency pneumatic and early warning system; Can avoid taking place because of pressure drop causes bleeding episode; Increase patient's trans-radial interventional therapy postoperative hemostatic effectiveness and safety, avoid prolonging with hospitalization cost and increasing creation huge social benefit and economic benefit because of the hospital stays due to the hemostasis related complication.
