Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a peripheral vascular catheterization blocker. Background Technology

[0002] With the continuous development of extracorporeal circulation technology, the extracorporeal circulation technology of large cardiac centers has become increasingly mature, and secondary and minimally invasive surgeries are becoming more and more common, which inevitably leads to peripheral cannulation. Due to the fact that these are secondary or minimally invasive surgeries, the surgical field and anatomy are difficult, which brings many challenges to cannulation in these surgeries, especially the cannulation block, which requires dissecting deep blood vessels and adding a clasp, making the procedure difficult and risky. Utility Model Content

[0003] The main purpose of this invention is to provide a peripheral vascular catheterization occlusion device, which aims to improve the convenience and safety of the procedure.

[0004] To achieve the above objectives, this utility model proposes a peripheral vascular catheterization occlusion device, comprising:

[0005] Intubation;

[0006] A connection interface is located at the proximal end of the cannula, and a side hole is provided on the outer peripheral wall of the connection interface;

[0007] A catheter, movably inserted into the cannula through the side port and extending to the distal end of the cannula, the proximal end of the catheter being adapted to communicate with a gas supply device; and

[0008] A blocking balloon, connected to the catheter and located at the distal end of the catheter, is used to block blood vessels.

[0009] Optionally, the peripheral vascular catheterization occluder further includes a connector, one end of which is connected to the proximal end of the catheter, and the other end of which is adapted to be connected to the gas supply device.

[0010] Optionally, a protective sleeve is fitted over the portion between the conduit and the connector to prevent air leakage and to protect the conduit.

[0011] Optionally, the protective cover is a medical plastic bag cover.

[0012] Optionally, the medical plastic bag is secured to the catheter by a cable tie.

[0013] Optionally, the connector is a three-way plug valve.

[0014] Optionally, the connection interface is a Luer interface.

[0015] Optionally, the distal outer peripheral wall of the cannula is provided with multiple through holes that allow fluid to pass through.

[0016] Optionally, the plurality of the through holes are evenly distributed in the circumferential and axial directions of the blocking airbag.

[0017] Optionally, the proximal end of the cannula is provided with a flared section, and one end of the connection interface is inserted and fixed in the flared section.

[0018] In this invention, the peripheral vascular catheterization occluder includes a cannula, a connecting interface, a catheter, and an occluder balloon. The connecting interface is located at the proximal end of the cannula, and a side hole is provided on the outer peripheral wall of the connecting interface. The catheter is movably inserted into the cannula through the side hole and extends to the distal end of the cannula. The proximal end of the catheter is adapted to communicate with an air supply device. The occluder balloon is connected to the catheter and located at the distal end of the catheter, and is used to occlude the blood vessel. This invention designs a peripheral vascular catheterization occluder. During the procedure, cannulation can be completed first using ordinary peripheral cannulation. Then, a slender catheter with an occluder balloon is inserted into the side hole of the connecting interface at the proximal end of the cannula. After the catheter extends out of the peripheral venous cannula, the occluder balloon is inflated by inflating the catheter, thus completing the occlusion of the peripheral cannula. It is evident that by using this invention, the peripheral vascular catheterization occluder effectively avoids the dangerous and difficult steps of dissecting deep blood vessels and applying an occlusion band, thereby greatly improving the convenience and safety of the procedure.

[0030] This invention proposes a peripheral vascular catheterization occlusion device.

[0031] Reference Figures 1 to 3In one embodiment of the present invention, the peripheral vascular catheter occlusion device includes a cannula 10, a connecting interface 20, a catheter 30, and an occlusion balloon 40; the connecting interface 20 is located at the proximal end of the cannula 10, and a side hole 20a is provided on the outer peripheral wall of the connecting interface 20; the catheter 30 is movably inserted into the cannula 10 through the side hole 20a and extends to the distal end of the cannula 10, and the proximal end of the catheter 30 is adapted to communicate with an air supply device; the occlusion balloon 40 is communicated with the catheter 30 and located at the distal end of the catheter 30, and the occlusion balloon 40 is used for vascular occlusion.

[0032] In this embodiment, to allow blood flow, multiple through holes 10a can be provided on the distal outer peripheral wall of the cannula 10 to allow fluid passage. The multiple through holes 10a are evenly distributed in the circumferential and axial directions of the blocking airbag 40, which is not limited here.

[0033] In this embodiment, the connection interface 20 can be a common Luer interface, and there is no limitation here. The catheter 30 can preferably be a slender medical catheter 30, similar to a Frey urinary catheter, or a clean and unused Frey urinary catheter can be used directly, and there is no limitation here.

[0034] This invention relates to a peripheral vascular catheterization occlusion device. During the procedure, a standard peripheral cannula 10 is first inserted. Then, a slender catheter 30 with an occlusion balloon 40 is inserted into the side hole 20a of the proximal end connection interface 20 of the cannula 10. After the catheter 30 extends beyond the peripheral venous cannula 10, the occlusion balloon 40 is inflated by inflating the catheter 30, thus occluding the peripheral cannula 10. It is evident that by employing this peripheral vascular catheterization occlusion device, the dangerous and difficult steps of dissecting deep blood vessels and applying an occlusion band are effectively avoided, thereby greatly improving the convenience and safety of the procedure.

[0035] For easy connection of cannula 10 and connection interface 20, refer to Figures 1 to 3 In some embodiments, the proximal end of the cannula 10 may be provided with a flared section 101, and one end of the connecting interface 20 is inserted and fixed in the flared section 101.

[0036] To facilitate the connection of the conduit 30 to the gas supply device and improve the convenience and safety of the procedure, refer to Figures 1 to 3 In one embodiment, the peripheral vascular catheterization occluder may further include a connector 50, one end of which is connected to the proximal end of the catheter 30, and the other end of which is adapted to be connected to a gas supply device.

[0037] In this embodiment, the connector 50 can be a three-way plug valve or the like, but is not limited here.

[0038] Furthermore, a protective sleeve 60 may be provided between the conduit 30 and the connector 50 to prevent air leakage and protect the conduit 30.

[0039] To save on surgical costs, the protective sleeve 60 can be made from a medical plastic bag. It is understandable that most components of this peripheral vascular catheterization occluder can be sourced locally, using commonly available hospital instruments or items, resulting in very low costs and convenient operation for the surgeon during the procedure.

[0040] In this embodiment, the medical plastic bag is secured to the catheter 30 by a cable tie 70 to ensure the stability of the medical plastic bag installation.

[0041] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
