Clinical use case
In strict accordance with doctor's operation working specification and technician's operation working specification, technician opens high pressure injector and embodiment
1 intelligent high-pressure injector handle installation's power source, the intelligence of the high pressure injector and embodiment 1 of being bought market by connecting line
The connection of high pressure injector handle apparatus, doctor carry out percutaneous coronary bracket to 72 years old male patient.
Patient's basic condition
Patient male, insult х х, 72 years old, because " 10 years after percutaneous transluminal coronary stent implantation, then sending out pectoralgia 2 days " is in 2018-02-09
Take in our hospital.There is precordial fullness pain suddenly in 10 Nian Qianwu inducement of patient, and to squeeze sample, paroxysmal breaks out continue 20-30 every time
Minute, it with palpitaition, feels suffocated and whole body cold sweat, does not radiate to elsewhere, cannot be relieved after rest, with dizzy, big belly, Zeng Yu
Local hospital is medical, looks into electrocardiogram prompt " acute inferior myocardial infarction ", blood troponin I positive is diagnosed as " coronary heart disease, urgency
Property lower wall myocardial infarction ", give the treatment such as " nitroglycerin, aspirin, Plavix ", above-mentioned symptom is relieved, but still is had
Slighter above-mentioned symptom, in August, 2009 are gone to a doctor in our hospital, and row coronary angiography shows triple vessel disease, are implanted into 5 pieces of bracket altogether.
Postoperative patient restores good, the long-term oral medicaments for coronary disease treatment of rule.Aspirin, Lipitor are oral so far, Plavix mouth
It takes 1 year.The morning 8:00 patient of on February 07th, 2018 is without bored pain under obvious inducement burst xiphoid-process, and range is in fist size, without him
Place's radiation, with slight dizzy, limbs fatigue, without sweat all over, Nausea and vomiting, amaurosis, headache, palpitaition, the discomforts such as shortness of breath, hold
Gradually alleviate after 1 hour continuous.The patient assessment of on February 08th, 2018 illustrates II, III, aVF lead pathologic in outer court, row electrocardio
Q wave, ST sections are raised 0.05mv.CKMB 17.52ng/ml, cTnI 17.51ng/ml, Myo 122.4ng/ml.Consider the acute heart
Flesh infarct, remaining ticagrelor load treatment.The present takes in my lesion for further treatment.
The past diabetes medical history, it is specifically unknown.Physical examination: Bp:106/60mmHg, weight 59kg, height 164cm.Biochemistry inspection
It looks into and shows creatinine: 94.21umol/L, hematocrit value: 37.3%.Electrocardiogram shows without exception.Color Sonography shows LVEF57%,
Meet the change of coronary heart disease ultrasound, Diastole Function decline, slight mitral regurgitation.
It is with the maximum contrast tolerance dose that the maximum contrast dose assessment system-computed of embodiment 1 goes out the patient
136.40ml。
Maximum injection total amount is infused as 136.40ml, single maximum in the art for setting contrast agent on the display of embodiment 1
Firing association's amount is 4ml, single maximum injection flow is 3ml and single maximum injection pressure is 700psi.It can also be by wirelessly passing
Defeated system connect injection handle with computer, then sets the above-mentioned injection data of contrast agent on computers.
In art: 02-11 row coronary angigraphy+percutaneous coronary intervention (pci), it is preoperative to give 0.9% physiological saline
500ml aquation, Results of Coronary Arteriography show narrow 70%, the LAD in the tail portion LM opening narrow 70%, the visible bracket shadow in nearly middle section, branch
Narrow 60%, the LCX opening of distal section and the narrow 50-60% of proximal segment diffusivity, the narrow 60-90% of distal section diffusivity in frame.Row LAD-
LM, LCX row PCI treatment are sent into 2 2.5*33mm drug stent of Firebird in LCX distal section lesion, are sent into the distal end LAD
Happy general 3.5*18mm drug stent.
Operation terminates, and technician closes high pressure injector and medicinal intelligent high pressure injector handle apparatus power supply, closes connection
Line 1.
Postoperative: the maximum contrast tolerance dose of patient is 136.40ml, and performs the operation and actually used 120ml contrast agent,
Patient checks creatinine 95.77umol/L (preoperative creatinine: 94.21umol/L) after returning to ward, and not sent creatinine is significantly raised, nothing
Radiographic contrast nephropathy occurs.
By above-mentioned clinical case as it can be seen that the intelligent high-pressure injector handle device of the present embodiment 1 can guarantee surgical procedure
The total amount for injecting contrast agent to patient is no more than its maximum contrast tolerance dose, avoids causing to suffer from because injecting excessive contrast agent
The compromised kidneys of person.
Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model rather than to this realities
With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is common
It will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this reality
With the spirit and scope of new technique scheme.
