The invention relates to an auxiliary device for coronary angiography, which comprises a main structure, a puncture auxiliary device, a guide wire auxiliary device, a post-operation fixing device and asupport frame body 1; puncture auxiliary device, seal wire auxiliary device and postoperative fixing device all set up on supportingframe body 1. Because the patient needs to puncture the radial artery when performing the coronary angiography operation, and then the subsequent operation of the coronary angiography operation is facilitated, the progress of the coronary angiography operation can be directly influenced by the quality of the radial artery puncture effect, and the radial artery puncture is of great importance for the coronary angiography. The puncture auxiliary device that this device set up is used for assisting the doctor to puncture radial artery, before carrying out the radial artery puncture, need carry out the fixed operation to radial artery to select suitable radial artery puncture position, the puncture angle of optimization when carrying out the radial artery puncture and carry out the degree of depth that the radial artery punctured according to different patients' particular case, and then the guarantee when carrying out the radial artery puncture, can have a good puncture effect, with going on of the follow-up operation of guarantee coronary angiography operation. The guide wire auxiliary device of the device is used for assisting in a series-in task before and after a guide wire is arranged in a series-in mode after puncture, for example, the guide wire is assisted in entering a radial artery and a progressive operation after the guide wire enters the radial artery, so that the guide wire can safely and effectively enter the radial artery and safely reach the heart coronary artery, the dangerous condition that the inner wall of a blood vessel is damaged after the guide wire penetrates the radial artery is avoided, and the safety of coronary angiography is further guaranteed. The postoperative fixing device of this device is used for carrying on the coronary angiography operation and accomplishes the back, because the pulsating reason of radial artery can follow puncture department outflow blood, consequently need fix hemostasis to radial artery and handle, avoids appearing the radial artery puncture department and bleed too much phenomenon. Because the effective realization of above-mentioned device of will being convenient for, consequently, puncture auxiliary device, seal wire auxiliary device and postoperative fixing device all set up on supporting thesupport body 1, and then make and support the wrist position that supportbody 1 can be to patient's radial artery, and then the operation that the doctor of being convenient for carried out the coronary angiography operation.

Support frame body 1:

when the coronary angiography task is normally performed, the wrist of the patient needs to be correctly placed, so that the radial artery at the wrist of the patient is ensured to be exposed, and medical staff can conveniently perform the coronary angiography operation task. Consequently,support 1 center of support frame body and transversely be provided withrecess 2 that is used for placing patient's wrist, and then make the patient when carrying out coronary angiography operation, the patient places the wrist inside 2 ofsupport frame body 1, and then carries out the injecing of position to patient's wrist, possesses a comfortable position of placing in order to make the patient simultaneously, consequently the inner wall ofrecess 2 is bionical form for adaptation patient's wrist shape that the device can be fine makes things convenient for the patient to carry out the wrist and places. In order to realize the degree of automatic auxiliary control of the device, an integrated circuit board and a wireless signal receiving and transmitting device are arranged inside thesupport frame body 1 and connected with a remote control terminal, so that when a worker uses the device to assist in performing a coronary angiography operation task, the automatic control of the device can be realized, and the device can effectively assist a doctor in performing the coronary angiography operation. In order to ensure that when the supportingframe body 1 is used for assisting in coronary angiography, the operation of a doctor on the radial artery of a patient cannot cause the change of the position of the whole device relative to the radial artery, therefore, the fixing device is arranged on the supportingframe body 1 and used for fixing the supportingframe body 1, so that medical personnel cannot easily change the position of the device when performing the contraction operation of coronary angiography, and further ensure that the medical personnel cannot change the position relation between the supportingframe body 1 and the wrist of the patient due to operation, and further avoid dangerous accidents caused by dislocation; the fixing device selected by the device can select the winding belt as the fixing device, and when the fixing device is used for fixing, the winding belt can be directly wound and fixed on the frame body. Because the time required when the coronary angiography is performed is about 1-3 hours, and the wrist of the patient is placed in thegroove 2 of thesupport frame body 1 for a long time, the wrist of the patient is stiff and difficult to perform the hemostasis fixing operation after the subsequent operation is completed, thesupport frame body 1 is covered with the medical soft sponge, and the thickness of the medical soft sponge is 1-3 mm. After the wrist of the patient is placed in thegroove 2 of thesupport frame body 1 for a long time, the phenomenon that the wrist is stiff due to long-time placement is avoided, so that convenience in fixing and stopping bleeding of the radial artery in the follow-up process is guaranteed; and the thickness of restriction medical soft sponge is for, when fixing hemostasis to patient's radial artery, need the tourniquet tightly to fix radial artery's nearly heart end, avoid the patient to appear the phenomenon of a large amount of losses of blood, and restrict the thickness of medical soft sponge, not only can ensure when fixing hemostasis, the patient can not experience the sense of pain of tightening comparatively, simultaneously also can not appear because medical soft sponge is too thick, and the phenomenon that fixed hemostasis is not fastened appears.

Puncture auxiliary device:

because the radial artery needs to be effectively punctured when a coronary angiography task is performed, the follow-up operation can be conveniently performed. In a radial artery puncture task under normal conditions, a doctor is required to firstly select an effective position for radial artery puncture according to experience. When a radial artery puncture task is performed, the optimal puncture position needs to be selected according to the beating conditions of different positions of the radial artery; the position with weaker pulse amplitude of the radial artery causes inconvenience for medical personnel to insert the puncture needle into the radial artery because the pulse amplitude is smaller; for the position with large radial artery pulsation amplitude, although the worker can insert the puncture needle into the radial artery most conveniently for puncture, after the coronary angiography is completed, the medical worker can not perform the hemostasis fixing operation because the pulsation amplitude is large, so that the position with the maximum radial artery pulsation amplitude is not the optimal position for puncture; as the optimal puncture position of the radial artery, the puncture position is the position between the maximum pulsation point and the minimum pulsation point, so that the puncture of medical personnel is facilitated, and the hemostasis fixing work after coronary angiography is also facilitated. Therefore, the upper end of thegroove 2 of thesupport frame body 1 is provided with the pressure detection cover plate 3, a relative sliding device is arranged between the pressure detection cover plate 3 and thesupport frame body 1, and the pressure detection cover plate 3 can be driven to slide back and forth on the upper end of thegroove 2. When the best position of radial artery puncture needs to be determined, after the wrist of a patient is placed in thegroove 2, the pressure detection cover plate 3 covers the radial artery of the wrist of the patient, and the pressure detection cover plate 3 is driven to move back and forth on the radial artery under the driving of the relative sliding device, so that the beating pressure of different positions of the radial artery is collected, and medical personnel can determine the best radial artery puncture position according to the detected radial artery beating pressure data. Because in this device, relative slider needs it to possess accurate slip ability, ensures that relative slider can realize accurate position change according to specific appointed, consequently, relative slider is the roller mechanism, the apron bottom surface bilateral symmetry of pressure detection apron 3 is provided with rolling wheel 9,support frame body 1recess 2 both sides are provided with the gyro wheel groove 108 with rolling wheel 9 matched with, be provided with in the rolling wheel 9 and be used for driving rolling wheel 9 pivoted steering wheel. Make pressure detection apron 3 can slide in the rolling groove according to the specific turned angle of steering wheel making rolling wheel 9, and then realize the accuracy nature of pressure detection apron 3 sliding position. Because the dynamics that everybody radial artery is beated can not be the same, and for make pressure detection apron 3 can the effectual radial artery of gathering different patients beat the power degree, consequently, be connected through electrictelescopic handle 12 between rolling wheel 9 and the pressure detection apron 3, and then ensure that the distance between pressure detection apron 3 and the sliding wheel can change, and then make pressure detection apron 3 can detect the radial artery change situation of beating of different patients. The limiting plate 11 that the rolling wheel 9 breaks away from the rolling groove is arranged at the upper end of the rolling groove, so that the rolling wheel 9 cannot break away from the sliding groove from an opening at the upper end of the sliding groove, and the strength of the pressure detection cover plate 3 which can accurately detect the radial artery pulsation is guaranteed. Because after the pressure detection of the radial artery is finished, in order to avoid the influence of the pressure detection cover plate 3 on the follow-up, the two end surfaces of the outer side of the rolling groove are opening end surfaces, so that the rolling wheel 9 can be arranged or slide out from the two end surfaces of the outer side of the rolling groove, and the task of detachably mounting the pressure detection cover plate 3 is further realized.

After determining the completion of the puncture location, a puncture is made to the patient's radial artery using the puncture. Because the beating strength of the radial artery and the thickness of the cortex on the radial artery of each person can be different, the conventional puncture needle inserting method controls the entering angle and the depth of a puncture needle through the long-term practical experience of doctors, is convenient for some old doctors to carry out, but for some young doctors with less practical experience, the expected puncture effect can not be achieved by puncturing once, and the injury can be caused to the peripheral vascular tissue of the memory of the radial artery. Therefore, the two limitingrods 4 are symmetrically arranged at two sides of thegroove 2 and are positioned on the same horizontal line; a relative sliding device is arranged between the limitingrod 4 and thesupport frame body 1, and the limitingrod 4 can be driven to slide back and forth at the upper end of thegroove 2 through a relative sliding mechanism. The end faces, close to the proximal ends, of the two limitingrods 4 are connected withguide tubes 5, and the included angle between eachguide tube 5 and each limitingrod 4 is 30-40 degrees. The relative sliding mechanism arranged here is the same as the relative sliding mechanism, and is used for adjusting the position of the limitingrod 4, so that medical staff can change the position of thecatheter 5 according to the optimal puncture position of the radial artery of different patients. The limitingrod 4 is vertically connected with the electrictelescopic rod 12 through an automatic telescopic device, so that the position change of theguide pipe 5 relative to the direction of thevertical groove 2 can be changed through the automatic telescopic device, and theguide pipe 5 is accurately arranged above the radial artery.

Thecatheter 5 is arranged here for limiting the puncture angle of the puncture needle, and when the puncture needle is used for radial artery puncture, the arrangement of thecatheter 5 plays a role of guiding; and when the conventional radial artery is punctured, the angle of the puncture needle head entering the radial artery is 30-40 degrees, so that the puncture needle can be easily punctured into the radial artery, and a follow-up guide wire is favorably conveyed into the radial artery from the puncture needle, so that the follow-up operations of heart stents and the like are facilitated. Because when carrying out the radial artery puncture, need assist to press radial artery both sides for the radial artery is outside protruding, conveniently carries out the radial artery puncture, consequently, two the nearly end that faces of 4 bottom surfaces of gag lever post all is provided withpresses chamber 13,press chamber 13 bottom surface opening, and inside is provided withpresses piece 14,press piece 14 and press to being connected through automatic telescoping device between thechamber 13. When carrying out the radial artery puncture task, the setting can be pressed the skin of radial artery both sides downwards according to thebriquetting 14 in pressingchamber 13 for the radial artery is prominent, and then makes things convenient for medical personnel to carry out the puncture task. The automatic telescoping device that here set up can drive transmission mechanisms such as lead screw nut for electric putter or servo motor and stretch out and draw back, and then realizes pressing down reciprocating ofpressure piece 14 in pressing downchamber 13 to guarantee that automatic telescoping device can press according to the condition of pressing of different patient radial artery departments, guarantee going on smoothly of radial artery puncture. In order to ensure that when thepressing block 14 presses the skin around the radial artery, the pressing end surface of thepressing block 14 is an arc-shaped soft end surface because the pressing force greatly affects the skin around the radial artery, so that thepressing block 14 can conveniently press the skin around the radial artery, and the arc-shaped soft end surface can prevent thepressing block 14 from excessively affecting the skin around the radial artery.

A guide wire auxiliary device:

in the coronary angiography operation, the guide wire is strung into the radial artery for the purpose of subsequent installation of the vascular sheath and theangiography catheter 5, so that the guide wire needs to be strung into the radial artery accurately to avoid influencing subsequent operation. When the traditional guide wire is strung in, medical staff needs to slowly send the guide wire into the radial artery through the needle hole of the puncture needle, so that the subsequent operation of coronary angiography is facilitated. When a radial artery guide wire feeding task is carried out, the damage to blood vessels around the radial artery is avoided, the vasospasm phenomenon caused by too fast feeding is avoided, a doctor is required to judge the speed of the guide wire to be fed into the radial artery according to long-time practical experience, and the doctor is not easy to better carry out the feeding task of the guide wire. Therefore, the guide wire auxiliary device comprises aguide wire tube 6 and aspeed measuring wheel 7, wherein wheel grooves 8 are symmetrically arranged on the side wall of the outer side end of theguide wire tube 6, and thespeed measuring wheel 7 is arranged inside the wheel grooves 8. When the guide wire passes through theguide wire tube 6 and is strung into the radial artery from the puncture needle, the guide wire is contacted with thespeed measuring wheels 7 on two sides of theguide wire tube 6, and then thespeed measuring wheels 7 are driven to rotate, so that the feeding amount of the guide wire in unit time is obtained. The tachometer is arranged in thetachometer wheel 7 arranged in the device, and the feeding amount in unit time when the guide wire is accurately detected to be serially connected to the radial artery, so that whether the feeding speed of the guide wire can damage the radial artery or not is detected, and whether the normal serial-in speed is met or not is judged. It should be noted here that the guide wire used after coronary angiography puncture is composed of a steel wire with strong toughness inside for supporting, and a medical silica gel wrapping the steel wire outside. Because when the supplementary task of going into of seal wire is assisted in installation seal wire auxiliary device, need be in the same direction as going into with the seal wire at the tip of pjncture needle, consequently, guidewire pipe 6 can be dismantled the connection and set up the needle-inserting end tip atpipe 5, and then makes after accomplishing the pjncture needle puncture, is connected topipe 5's tip withguide wire pipe 6 again, conveniently carries out the operation that the seal wire went into. When a guide wire stringing task is carried out, in order to ensure that the stringing of the guide wire can effectively drive thespeed measuring wheel 7 to rotate, slidinggrooves 15 are transversely and symmetrically arranged on the groove surfaces on two sides of the wheel groove 8, slidingblocks 16 matched with the slidinggrooves 15 are arranged in the slidinggrooves 15, and a rotating shaft of thespeed measuring wheel 7 is rotatably connected with the slidingblocks 16; the outer end face of the slidinggroove 15 is provided with aspring 17 connected with a slidingblock 16. When the guide wire is threaded in, the guide wire drives thespeed measuring wheels 7 on the two sides to rotate, and due to the arrangement of thespring 17, thespring 17 can generate an effective thrust based on thespeed measuring wheels 7, so that an interaction force is generated between the guide wire and thespeed measuring wheels 7, and thespeed measuring wheels 7 are driven to rotate effectively; and because the types of the guide wires are different, the slidinggroove 15 is matched with the slidingblock 16, so that the position of thespeed measuring wheel 7 can be changed, and the guide wires are suitable for being connected with the guide wires with different diameters in a serial mode. Thespring 17 provided here has a coefficient of elasticity that cannot be too large, so as to avoid the phenomenon that the guide wire cannot smoothly cross into the guide wire when crossing into the guide wire, and the coefficient of elasticity is preferably such that the twotachometer wheels 7 can just contact each other without crossing into the guide wire. In order to enable thespeed wheel 7 to effectively rotate when the guide wires are threaded in, the wheel surface of thespeed wheel 7 is a rough wheel surface, and the guide wires are threaded in to effectively drive thespeed wheel 7 to rotate. In addition, when a guide wire is strung into a task, in order to ensure that the position of the guide wire cannot be dislocated, the center wheel surface of thevelocity measuring wheel 7 is provided with an inward-concave guidewire limiting groove 18, so that the position of the guide wire cannot be deflected when the guide wire is strung into the velocity measuring wheel, and the guide wire can be effectively strung into the velocity measuring wheel. When themeasuring wheel 7 detects that the guide wire is fast in serial speed, medical personnel are effectively reminded, therefore, themeasuring wheel 7 is connected with analarm 19, and then the use rate is too fast to be effectively observed by the medical personnel. And after the guide wire is completely strung, theguide wire tube 6 is disassembled, the puncture needle is pulled out, the guide wire is left in the radial artery, the puncture auxiliary device is disassembled, and then a space for subsequent installation of a vascular sheath and stringing operation of theangiography catheter 5 is reserved.

Postoperative fixing device:

the postoperative fixing device that this device set up is used for stopping bleeding fixedly to radial artery puncture department. After coronary angiography is performed, the radial artery needs to be fixed for hemostasis, so that the radial artery after coronary angiography cannot bleed in a large amount. The conventional coronary angiography hemostasis method is characterized in that a tourniquet is fixed at the proximal end of a radial artery, so that the radial artery does not bleed in a large amount, but the tourniquet is used for hemostasis, so that the radial artery at the wrist of a patient and blood of peripheral blood vessels do not circulate, the wrist of the patient is stiff, and the subsequent normal recovery of the wrist of the patient is not easy. The mode that adopts the gasbag area to fix conveniently fixes, and can make wrist department hemostasis gasbag possess a best hemostasis fastening degree, but the hemostasis mode uncertainty of hemostasis gasbag can be very big, and the operation when aerifing is no longer comparatively troublesome, and inconvenient medical personnel operate. Therefore, the postoperative fixing device comprises aninflator pump 20 and afastening belt 21, wherein theinflator pump 20 is arranged on one side of thesupport frame body 1, theinflator pump 20 is connected with a strip-shapedair bag belt 22, thefastening belt 21 wraps the outer side of the strip-shapedair bag belt 22, and a hangingring 23 is arranged at the outer end of thefastening belt 21; the fixing end face of thefastening belt 21 is provided with a hemostaticair bag belt 24, the strip-shapedair bag belt 22 is communicated with the hemostaticair bag belt 24, and the other side of thesupport frame body 1 is provided with ahook 25 matched with the hangingring 23. After the coronary angiography operation is completed, when the radial artery of a patient needs to be subjected to hemostasis fixing, the hangingring 23 at the outer end of thefastening belt 21 is hung on thehook 25 of thesupport frame body 1, and then the subsequent inflation hemostasis is convenient. And because thefastening band 21 wrapping the strip-shapedair bag band 22 plays a role in limiting the strip-shapedair bag band 22 from excessively deforming during inflation, a large amount of air is prevented from existing in the strip-shapedair bag band 22, so that the air can normally play a role, and therefore, the strip-shapedair bag band 22 is made of a non-elastic material. So that the gas in the inflator 20 can be more fully flushed into thetourniquet air bag 24, and the gas can fully exert the function. When the radial artery hemostatic belt is used, theinflator 20 is used for flushing gas into the strip-shapedair bag belt 22, and the strip-shapedair bag belt 22 is used for flushing gas into the hemostaticair bag belt 24, so that the inflation quantity is determined according to the radial artery hemorrhage condition of a patient. When inflating, in order to avoid making a large amount of gas rush intotourniquet belt 24 with faster speed because of aerifing, make medical personnel can not be fine control speed of inflating, consequently,strip gasbag area 22 is provided withelectronic overflow valve 26 with the junction oftourniquet belt 24, and then avoids appearing a large amount of gas rush intotourniquet belt 24 and make medical personnel's unable normal control speed of inflating's phenomenon.

The using method comprises the following steps:

when using, placesupport frame body 1'srecess 2 with patient's wrist level in, and use fixing device to carry out effective fixed with this device, and then carry out follow-up operation.
