Description
Technical field
The utility model relates to the field of medical instrument technology, the especially micro infusion device of high-voltage pulse type thrombolysis.
Background technique
With the development of reform and opening-up, the living standard of the people is also increasingly improved, and various all kinds of delicacies, delicious food are also confused
Dining table confusingly has been brought up to, however, what is followed closely is the generation of various rich people's diseases, such as three Gao Wenti (i.e. blood glucose is high, blood lipid is high,
High blood pressure) caused by various diseases, be mainly formed by thrombus by substances such as blood lipid, bad cholesterol and plug blood vessel,
Lead to the generation of the diseases such as limbs blood supply insufficiency, diabetes, amputation in arterial disease.Lower limb deep venous thrombosis (deep
Vein thrombosis, DVT) it is vascular surgery common disease, pulmonary embolism caused by thrombosis can seriously threaten patient
Life, disease incidence obviously increases in recent years, operation, wound, hip fracture, and patient's hip, knee prosthesis are postoperative not to be taken
Precautionary measures, DVT disease incidence is up to 42.6%~48.4%, and wherein malignant tumour, advanced age, gestation, long-term bed are patient's hairs
Raw DVT common risk factor.Although Operative thrombectomy can directly open vein obstruction, shorten the obstructive symptom time, wound compared with
Greatly, medium sized vein incision causes vein wall damage thrombus to be easy to be formed again, and reverse pulling plug can cause vein valve different degrees of
Damage, and traditional simple anticoagulant, Operative thrombectomy, the Clinical efficacy and safety of system thromboembolism treatment are all not fully up to expectations,
Recently as the development of vascular surgery interventional therapeutic technique, Catheter Thrombolysis art (catheter directed
Thrombolysis, CDT) be increasingly being applied to the treatment of DVT, and can effective prevention of deep vein thrombosis sequelae hair
It is raw, there is good clinical effectiveness.Treatment for antithrombotic, although having the drug of various thrombus, and effect is good
Good, energy dissolve blood lipid rapid, significantly, cholesterol is formed by thrombus, and thrombus object accompanying on vascular wall is removed completely,
But it is often unsatisfactory to treat apoplexia disease effect, this is because thrombus object, after falling off, blocking blood vessel, which has formed
Blind pipe lacks fluid exchange, therefore thrombolytic drug is difficult to close to the thrombus object, thus curative effect is little or even fails, and thrombus is stifled
The time of plug is longer, and the degree for lacking the tissue damageds such as the nerve of blood supply is also more serious, to restore the hope of its normal function
It is more remote, through catheter contact thrombolysis, directly urokinase can be pumped into thrombus using the thrombolysis catheter of indwelling, hence it is evident that increase
The blood concentration of part, also substantially reduces hemorrhage complication while improving efficiency of thrombolysis, reduces the dosage of systemic drug.?
In vascular diseases treatment clinic, commonly using the method for minimally-invasive treatment, thrombolysis medical fluid is passed through into syringe or infusion pump and special
Thrombi of the catheter propelling into blood vessel, i.e., it is (opposite using high speed and high pressure by thrombolytic drug pressure injection to thrombi
For thrombi in blood) medical fluid impact make the thrombi fragmentation for blocking vascular access, however lesser thrombi exists
The lower ablation of thrombolysis medical fluid effect is to achieve the purpose that eliminate thrombi in blood vessel.But it is above-mentioned using conventional infusion pump or artificial
Injection system haves the defects that certain, pumps quantitative constant speed using conventional infusion and is infused the thrombi into blood vessel, but by
In medical fluid be quantitative constant speed, medical fluid for thrombi impact force continued for constant, cannot as manual injection by using
Thrust of different sizes impacts thrombi with different impact forces；And syringe is injected by hand, is inconvenient, and is especially often pushed away primary
It requires to unload syringe, has not only increased hygienic infection risk, but also increase medical staff's burden.
