Abstract

The utility model discloses a kind of catheters, including tube body, one end of the tube body is catheter tip, other end connection is equipped with urine outlet and cleaning injection port, the cleaning injection port is equipped with syringe connection mouth, and guiding steel wire is equipped in the tube body, and the tube body is equipped with tip sacculus close to the position at the catheter tip, tube body between the tip sacculus and the catheter tip is equipped with urine filling mouth, and the tip sacculus is equipped with thrombolysis hole.The utility model compared with prior art the advantages of be: cost is relatively low, guiding steel wire has certain flexibility, narrow section or thrombus section can be passed through, color ultrasound guidance development is clear, tip balloon pressure is small, having certain compliance when taking bolt not will lead to the tearing of blood vessel, and there are thrombolysis Kong Houke that accurate thrombolysis can be carried out under color ultrasound guidance for tip sacculus.

Description

A kind of catheter

Technical field

The utility model relates to the field of medical instrument technology, in particular to a kind of catheters.

Background technique

Internal arteriovenous fistula is hemodialysis patients " lifeline ", and internal fistula is easy to appear thrombus in use and causes Internal fistula loses function, and existing Fogarty foley's tube takes effect in bolt preferable in internal fistula, but it is expensive, furthermore balloon pressure Excessive that vascular tear is easy to cause during taking bolt, how providing one kind, cost is relatively low, color ultrasound guidance development is clear and will not Leading to the catheter of vascular tear becomes research topic.

Utility model content

The purpose of this utility model is to solve the problems, such as to mention in background technique, and providing one kind, cost is relatively low, color ultrasound guidance Development is clear and not will lead to the catheter of vascular tear.

In order to solve the above technical problems, technical solution provided by the utility model are as follows: a kind of catheter, including tube body, institute The one end for stating tube body is catheter tip, and other end connection is equipped with urine outlet and cleaning injection port, and the cleaning injection port is set There is syringe connection mouth, is equipped with guiding steel wire in the tube body, the tube body is set close to the position at the catheter tip There is tip sacculus, the tube body between the tip sacculus and the catheter tip is equipped with urine filling mouth.

As a preferred embodiment, the tip sacculus is equipped with the thrombolysis of desirable hemodialysis thrombosis in arteriovenous fistula Hole.

The utility model compared with prior art the advantages of be: cost is relatively low, and guiding steel wire has certain flexibility, can be suitable Benefit is by narrow section or thrombus section, and color ultrasound guidance development is clear, and tip balloon pressure is small, has certain compliance will not when taking bolt Lead to the tearing of blood vessel, there are thrombolysis Kong Houke that accurate thrombolysis can be carried out under color ultrasound guidance for tip sacculus.

Detailed description of the invention

Fig. 1 is a kind of structural schematic diagram of catheter of the utility model.

It is as shown in the figure: 1, tube body, 2, catheter tip, 3, urine outlet, 4, cleaning injection port, 5, syringe connection mouth, 6, Guiding steel wire, 7, tip sacculus, 8, urine filling mouth, 9, thrombolysis hole.

Specific embodiment

The following describes the utility model in further detail with reference to the accompanying drawings.

In conjunction with attached drawing, a kind of catheter, including tube body 1, one end of the tube body 1 are catheter tip 2, other end connection Equipped with urine outlet 3 and cleaning injection port 4, the cleaning injection port 4 is equipped with syringe connection mouth 5, is equipped in the tube body 1 Guiding steel wire 6, the tube body 1 close to the catheter tip 2 position be equipped with tip sacculus 7, the tip sacculus 7 with Tube body 1 between the catheter tip 2 is equipped with urine filling mouth 8.

As a preferred embodiment, the tip sacculus 7 is equipped with the thrombolysis of desirable hemodialysis thrombosis in arteriovenous fistula Hole 9.

In the specific implementation, guide wire is guided by catheter increases catheter hardness to the utility model, makes Catheter can pass through internal fistula diseased region；Color ultrasound positioning narrow section or thrombus section in advance, determine pathological lumen diameter, select The catheter of suitable diameter cuts after local anaesthesia and does a stringer notch or detachment vein end at the nearly previous anastomotic of vein, by narrow Injection heparin saline enters tip sacculus after section or thrombus section, slowly pulls out catheter, is slowly pulling out in catheter procedure constantly Intracapsular water is adjusted, makes water pocket uniformly and vascular wall is close to being taken out thrombus using traction action of the water pocket to thrombus, so Repeatedly until being pulled out there is no thrombus.Color ultrasound examination if still there is lateral thrombus determines thrombi again in art, in water Capsule windowing, catheter water pocket position is sent to lateral thrombus, slowly inject urokinase in catheter-balloon side under color ultrasound guidance, Urokinase concentration is 50,000 U/ml, retains about after twenty minutes, takes bolt again with the above method.

The utility model and embodiments thereof are described above, this description is no restricted, shown in attached drawing Be also one of the embodiments of the present invention, actual structure is not limited to this.All in all if this field Those of ordinary skill is enlightened by it, without deviating from the purpose of the present invention, not inventively design with The similar frame mode of the technical solution and embodiment, all should belong to the protection range of the utility model.
