By providing positive pressure for the cavity between the sheath and the catheter, the medicine is slowly released from the sheath to the blood vessel, so that the effects of dilating local blood vessel and anticoagulation are achieved.
Preferably, the open end is disposed at the tail end of the sheath.
Preferably, a hemostatic valve is arranged in the sheath tube near the tail end of the sheath tube.
The hemostatic valve adopts an elastic member with a central gap hole, such as a silica gel member, when the catheter is penetrated, the hemostatic valve tightly packs the catheter by self elasticity to prevent blood from overflowing, and when the penetrating device is replaced, the hemostatic valve can tightly seal the gap hole by self elasticity to prevent blood from overflowing.
Preferably, the side wall of the sheath tube is provided with a side end inlet, and the side end inlet is connected with the pressure medicine supply assembly through a pipeline.
Preferably, the side end inlet is positioned in the front end direction of the hemostatic valve.
By arranging the side inlet channel in the front end direction of the hemostatic valve, the pressure drug supply assembly can avoid overflowing from the tail end of the sheath tube when providing positive drug supply pressure for the cavity between the sheath tube and the catheter.
Preferably, the pressure delivery assembly includes an elastic reservoir and a drug stored within the elastic reservoir.
Preferably, the drug is provided as a cocktail drug containing heparin sodium and nitroglycerin to prevent thrombosis.
The elastic liquid storage bag provides elastic retraction force, and the cocktail medicine containing heparin sodium and nitroglycerin is always pressed into the sheath tube during treatment.
The device for preventing thrombus formation in the hepatic artery perfusion chemotherapy sheath through radial artery access provided by the utility model has the advantages that the medicine is slowly released from the sheath to the blood vessel through automatic pressurization administration, so that the effects of dilating local blood vessel and anticoagulation can be achieved, and the problem of thrombus formation between radial artery and sheath can be effectively avoided. Can also be combined with subcutaneous injection of low molecular heparin to produce the aim of synergistic effect.
