Abstract
The utility model discloses a novel device for thrombolysis treatment of arteriovenous internal fistula, which belongs to the field of medical equipment. The novel device comprises a ureteral catheter, a Y-shaped puncture guide needle and a scalp needle, wherein the diameter of the ureteral catheter is less than that of the needle head of the Y-shaped puncture guide needle, one end of the ureteral catheter penetrate \ the needle head of the Y-shaped puncture guide needle after passing through the side hole of Y-shaped puncture guide needle, the other end of the ureteral catheter is connected with the needle point of the scalp needle, the other end of the scalp needle is connected with an injector A, and holes are formed on the ureteral catheter. The ureteral catheter is sent into the arteriovenous internal fistula through the side hole of the Y-shaped puncture guide needle, the Y-shaped puncture needle is pulled out, and the pumping push of thrombolysis medicine can be carried out through the injector A, so that local thrombolysis therapy through high-concentration medicine can be carried out. The novel device for thrombolysis treatment of arteriovenous internal fistula has the advantages of simple structure, convenience in operation, and high thrombolysis efficiency.
Description
Technical field
This utility model relates to a kind of thrombolytic apparatus, particularly a kind of internal arteriovenous fistula thrombolytic device.
Background technology
The thromboembolism treatment of internal arteriovenous fistula generally is the systemic vein thrombolytic clinically, and the side effect of whole body thrombolytic is many, weak effect.The needle point of being is also arranged towards the internal fistula direction tremulous pulse that directly punctures, inject thrombolytic drug and carry out thrombolytic, but thrombolytic drug can't touch thrombosis at once like this, thrombolytic efficient is low.Nurse's tremulous pulse difficulty that punctures, arterial pressure is big, forms hematoma easily, and patient's arm in the thrombolytic process can not move simultaneously, also reduces patient's treatment compliance.
In addition, ureteral catheter is a medical apparatus and instruments commonly used clinically, but generally is not used in thrombolytic.
The utility model content
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of simple in structure, easy to use, novel internal arteriovenous fistula thrombolytic device that thrombolytic efficient is high.
The technical solution adopted in the utility model is such: a kind of novel internal arteriovenous fistula thrombolytic device, comprise ureteral catheter, Y type puncture guiding needle and scalp acupuncture, the diameter of described ureteral catheter is less than the diameter of Y type puncture guiding needle syringe needle, the side opening of one end of described ureteral catheter by Y type puncture guiding needle passes from the syringe needle of Y type puncture guiding needle, the other end of ureteral catheter links to each other with the needle point of scalp acupuncture, the other end of described scalp acupuncture also connects a syringe A, also has the hole on the described ureteral catheter.
As preferably: described ureteral catheter external diameter is 1mm, and the diameter in the hole on the described ureteral catheter is 0.45mm, and the internal diameter of described scalp acupuncture is 0.55mm.
As further preferred: described Y type puncture guiding needle also connects a syringe B.
Carry out the ultrasonic examination of internal fistula thrombosis before the thrombolytic earlier, measure thrombosis length, prick the hole then on ureteral catheter, ureteral catheter matter is soft, and it is easy to prick pore volume, adjusts the length of pricking the hole according to thrombosis length; The Y type puncture guiding needle of dark Vein Tube is punctured into internal fistula, ureteral catheter is sent into internal arteriovenous fistula from the side opening of Y type puncture guiding needle, the side opening of an end by Y type puncture guiding needle that is ureteral catheter passes from the syringe needle of Y type puncture guiding needle, send into the length of internal arteriovenous fistula and adjust, can operate by the scale of observing on the ureteral catheter according to thrombosis length.Connect the ureteral catheter other end with scalp acupuncture, connect syringe A again, pump pushes away thrombolytic drug, can carry out high local concentrations medicine thromboembolism treatment.Y type puncture guiding needle connects a syringe B, and the effect of syringe B is when Y type puncture guiding needle enters internal fistula, with syringe B pumpback blood is arranged, and can assist to judge guide needle in internal fistula, and the assistance of syringe B is arranged, the more convenient operation of Y type puncture guiding needle.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are: ureteral catheter originally has only two side openings of head end, can obviously increase the area that thrombosis contacts with urokinase after manually pricking the hole in treatment, carry out thrombolytic faster, thrombolytic efficient improves greatly; Ureteral catheter head end circle is blunt, can injured blood vessel, owing on the ureteral catheter scale is arranged, one lattice are represented 1cm, and every 10cm has individual mark, can measure the length that conduit is sent into easily, and ureteral catheter matter is soft, patient's arm in the thrombolytic process can move, and is more convenient, the misery of having avoided the puncture tremulous pulse to bring to the patient.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Labelling among the figure: 1 is ureteral catheter, and 2 is the hole, and 3 is Y type puncture guiding needle, and 4 is scalp acupuncture, and 5 is syringe A, and 6 is syringe B.
The specific embodiment
Below in conjunction with accompanying drawing, this utility model is done detailed explanation.
In order to make the purpose of this utility model, technical scheme and advantage clearer,, this utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation this utility model, and be not used in qualification this utility model.
As shown in Figure 1, carry out the ultrasonic examination of internal fistula thrombosis before the thrombolytic earlier, measure thrombosis length, on ureteral catheter 1, prick out a sector hole 2, the diameter in each hole 2 is 0.45mm, adjust the length in the hole of being pricked on the ureteral catheter 12 according to thrombosis length, the Y type puncture guiding needle 3 of dark Vein Tube is punctured into internal fistula, the side opening of an end by Y type puncture guiding needle 3 that is ureteral catheter 1 passes from the syringe needle of Y type puncture guiding needle 3, ureteral catheter 1 is sent into internal arteriovenous fistula from the side opening of Y type puncture guiding needle 3, to all send in the thrombosis of internal arteriovenous fistula according to that section ureteral catheter 1 that thrombosis length is pricked hole 2, extract Y type puncture guiding needle 3, on the ureteral catheter 1 scale is arranged, (its internal diameter is 0.55mm with No. 5 half a head sword-shaped needles 4, length is 20mm) needle point connect ureteral catheter 1 other end, the other end of scalp acupuncture 4 connects syringe A5, pump pushes away thrombolytic drug, can carry out high local concentrations medicine thromboembolism treatment, Y type puncture guiding needle 3 also connects a syringe B6, when Y type puncture guiding needle 3 enters internal fistula, with syringe B6 pumpback blood is arranged, can assist to judge that guide needle is in internal fistula, and the assistance of syringe B6, the more convenient operation of Y type puncture guiding needle arranged.
The above only is preferred embodiment of the present utility model; not in order to restriction this utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
