A kind of vena cava filter device that discharges thrombolytic drugTechnical field
Patent of the present invention belongs to medical apparatus and instruments, is specially a kind of vena cava filter device that discharges thrombolytic drug.
Background technology
For the generation of prevention pulmonary infarction effectively, place defecator at caval vein, the free embolus in interception blood, the extensive use at home of this technology.
Current vena cava filter is intercepted after thrombosis in patient's body, conventionally uses the method for retaining venipuncture, and thrombolytic drug is injected to vein, treatment thrombosis.And the treatment of retaining venipuncture thrombolytic, patient not only will suffer the misery of secondary puncture, and needs medical personnel must have skilled operating technology, due to catheter retaining intravenous, the complication such as infection and conduit obstruction that conduit is relevant especially easily occurs.
Summary of the invention
The present invention seeks to solve existing vena cava filter and can only in caval vein, tackle thrombosis, can not treat thrombosis, patient thrombosis, need to do secondary venipuncture operation, bear the deficiency of secondary puncture operation risk, provide a kind of rational in infrastructure, reliable, easy to operate, a kind of vena cava filter device that discharges thrombolytic drug that security performance is high.
advantage of the present invention and beneficial effect:
A kind of vena cava filter device that discharges thrombolytic drug provided by the invention, by the drug release head with multiple irregular holes, be placed in filter central authorities, release head connects drug delivery pipe and is placed in filter body connecting pipe, and the drug delivery pipe other end is provided with medicine and injects hole.This device utilizes vena cava filter interception thrombosis, thrombolytic drug is injected to hole by medicine, inject the drug delivery pipe in filter body connecting pipe, if filter is intercepted thrombosis, by multiple irregular holes, thrombolytic drug is directly injected to thrombosis, to venous patient puncture thrombolytic, reduce patient's secondary injury without again, the risk of avoiding venous patient puncture for treating to bring is a kind of vena cava filter device that interception thrombosis, while thrombolytic effect are united two into one.
Brief description of the drawings
fig. 1 is that the present invention forms structural representation
fig. 2 is the head of drug release shown in Fig. 1 enlarged drawing
fig. 3 is the enlarged drawing of drug delivery pipe shown in Fig. 1
Detailed description of the invention
As can be seen from Figure 1, a kind of vena cava filter device that discharges thrombolytic drug, comprises filter main body, and the other end of the drug release head in multiple irregular holes, the drug delivery pipe of Connection Release head, drug delivery pipe is provided with medicine and injects hole.
Feature of the present invention is that the described drug release head with multiple irregular holes is placed in filter central authorities, as shown in Figure 2; The drug delivery pipe of Connection Release head is placed in filter body connecting pipe, and carrier pipe one end is provided with medicine and injects hole, as shown in Figure 3.
The present invention utilizes vena cava filter to intercept thrombosis in patient's caval vein, thrombolytic drug is injected to hole injection of medicine carrier pipe from medicine, thereby directly inject to thrombosis by being positioned at multiple irregular holes on drug release head, without again to venous patient puncture thrombolytic, reduce patient's secondary injury, avoid venous patient puncture smelting to treat the risk of bringing, it is a kind of vena cava filter device that interception thrombosis, while thrombolytic effect are united two into one, this device is simple to operate, safe, is applicable to promoting the use of.
