Abstract
Description
Technical Field
[0001] The utility model relates to the field of vascular sheaths, in particular to a vascular sheath that is convenient to use. Background Art
[0002] Vascular sheath is a disposable medical device used for transvascular interventional treatment. It is used to establish a pathway for transvascular interventional angiography and treatment. Vascular interventional treatment is a relatively safe and widely used treatment option in recent years. These treatments require establishing a channel from the outside of the body to the blood vessel. The vascular sheath enters the vascular lumen through the guidance of a puncture guidewire. The valve body is outside the human body, thus establishing a channel from the outside of the body to the vascular lumen. It can be used for other products to enter the blood vessels for treatment. With the promotion of application, there are higher clinical use requirements for vascular sheaths. Better vascular sheath delivery performance makes treatment safer and surgery smoother.
[0003] However, the current vascular sheaths have some shortcomings. When the vascular sheath is placed, since the three-way valve is connected to the one-way valve body through the side branch tube, and the side branch tube has a certain toughness, there is a certain distance between the three-way valve and the vascular sheath body. Therefore, when holding the vascular sheath, in order to avoid the three-way valve from colliding with foreign objects, the three-way valve and the vascular sheath need to be grasped together, which is troublesome. Utility Model Content
[0004] The main purpose of the utility model is to provide a vascular sheath that is easy to use and can effectively solve the problems in the background technology.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A convenient-to-use vascular sheath comprises a one-way valve body and a vascular sheath body, wherein a side branch is fixedly mounted on the surface of the one-way valve body, the vascular sheath body is fixedly mounted on the lower surface of the one-way valve body, a three-way valve is fixedly mounted on one end of the side branch, and a cone sleeve is provided on the movable surface of the vascular sheath body.
[0007] Preferably, a connector is fixedly mounted on the surface of the one-way valve body, and an insert is fixedly mounted on the surface of the one-way valve body and below the connector.
[0008] Preferably, the cone sleeve comprises a cone tube, a ring and a buckle, the upper surface of the cone tube is fixedly mounted with the ring, the curved surface of the ring is provided with a slot, and the surface of the cone tube and the buckle is fixedly mounted at the upper part.
[0009] Preferably, the number of the inserting strips and the slots is two, the number of the buckles is three, and the three buckles are distributed on the surface of the cone tube in a triangular shape.
[0010] Preferably, the lower end of the insert is embedded in the slot, and the other end of the side branch pipe is fixed to the connector.
[0011] Preferably, the three-way valve is connected to the one-way valve body through a side branch pipe.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] In the utility model, a one-way valve body, a cone sleeve and a vascular sheath body are arranged in a manner that cooperate with each other. When the vascular sheath is not in use, the cone sleeve is moved downward. When the cone sleeve is lowered to a certain height, the end of the side branch tube is clamped in the buckle of the cone sleeve. In this way, when the vascular sheath is held, the three-way valve will not collide with foreign objects. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0019] like Figure 1-3 A convenient-to-use vascular sheath is shown, comprising a one-way valve body 1 and a vascular sheath body 2. A side branch tube 3 is fixedly installed on the surface of the one-way valve body 1, the vascular sheath body 2 is fixedly installed on the lower surface of the one-way valve body 1, a three-way valve 4 is fixedly installed on one end of the side branch tube 3, and a cone sleeve 5 is movablely provided on the surface of the vascular sheath body 2.
[0020] A connector 102 is fixedly installed on the surface of the one-way valve body 1, and an insert strip 101 is fixedly installed on the surface of the one-way valve body 1 and below the connector 102. There is a certain friction between the insert strip 101 and the slot 504, which can prevent the cone sleeve 5 from sliding down; the cone sleeve 5 includes a cone tube 501, a collar 502 and a buckle 503. The upper surface of the cone tube 501 is fixedly installed with a collar 502, and a slot 504 is provided on the curved surface of the collar 502. A buckle 503 is fixedly installed on the surface of the cone tube 501 and located above, and the buckle 503 can be used for fixing the side branch pipe 3; the number of the insert strip 101 and the slot 504 is two, and the number of the buckles 503 is three, and the three buckles 503 are distributed in a triangular shape on the surface of the cone tube 501; the lower end of the insert strip 101 is embedded in the slot 504, and the other end of the side branch pipe 3 is fixed to the connector 102; the three-way valve 4 is connected to the one-way valve body 1 through the side branch pipe 3.
[0021] It should be noted that the utility model is a vascular sheath that is easy to use. During use, when the vascular sheath is not in use, the cone sleeve 5 is moved down. After the cone sleeve 5 is lowered to a certain height, the end of the side branch tube 3 is clamped in the buckle 503 of the cone sleeve 5. In this way, when the vascular sheath is held, the three-way valve 4 will not collide with foreign objects. However, when the three-way valve 4 needs to be used, the three-way valve 4 is removed from the buckle 503, and then the cone sleeve 5 is moved up until the insertion strip 101 is inserted into the slot 504 of the cone sleeve 5. In this way, the cone sleeve 5 can be effectively placed when not in use.
[0022] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
