Description

Technical Field

[0001] This utility model relates to the field of medical consumables technology, and in particular to disposable sidewall multidirectional catheter sheaths. Background Technology

[0002] The catheter sheath is one of the auxiliary guiding devices for peripheral and intracardiac minimally invasive interventional procedures, playing a crucial role in percutaneous coronary intervention, percutaneous interventional closure, and atrial septal puncture. It is used to establish a connection between the body's blood vessels and the external environment, assisting in the delivery system to transport diagnostic or therapeutic instruments to the target lesion site.

[0003] Current catheter sheaths are either single-tube designs or multi-tube channels formed by connecting multiple valve bodies, but these valve bodies are relatively large and the operation is also quite cumbersome. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the current catheter sheath is a single tube design, or a multi-tube channel is formed by connecting multiple valve bodies, but such valve bodies are relatively large and the operation is also relatively complicated.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a disposable sidewall multidirectional catheter sheath, including a catheter sheath body, a main valve body and an expander installed on the catheter sheath body, the interior of the main valve body is connected to the interior of the catheter sheath body, the interior of the main valve body has an integrally structured funnel-shaped internal material guide cover, the outer side of the main valve body is provided with a lateral receiving groove, and a flip-close cover plate and a drainage tube are movably assembled inside the lateral receiving groove.

[0006] One end of the drainage tube is fixedly installed on the outer arc surface of the funnel-shaped inner material guide cover, and the other end of the drainage tube is fixedly connected to the inner wall of the flip-closed cover plate.

[0007] The main valve body has an integrally structured lateral limiting block located at the opening of the lateral receiving groove on its outer side.

[0008] The outer side of the main valve body is provided with an arc-shaped operating groove at the opening of the lateral storage groove, which facilitates the flipping and closing of the cover plate.

[0009] A lateral isolation plate is fixed between the main valve body and the funnel-shaped internal material guide cover.

[0010] An inner locking frame is fixed on the inner side of the flip-close cover.

[0011] The beneficial effects of this utility model are:

[0012] (1) The disposable sidewall multidirectional catheter sheath of this utility model has a lateral storage groove set on the outside of the one-way valve, and a flip-closed cover plate with a built-in drainage tube is movably assembled inside the lateral storage groove. The opening and closing can be controlled by flipping the flip-closed cover plate inward and outward.

[0013] (2) The main valve body has an integrated funnel-shaped internal guide cover. The gap between the funnel-shaped internal guide cover and the main valve body is used to accommodate the drainage pipe, making reasonable use of the lateral space, resulting in a more reasonable layout and a smaller size. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] Figure 1 This is a schematic diagram of the structure of this utility model.

[0016] Figure 2 This is a schematic diagram of the internal structure of the main valve body in this utility model. Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Figure 1 and Figure 2 The disposable sidewall multidirectional catheter sheath shown includes a catheter sheath body 1, a main valve body 2 and an expander 3 installed on the catheter sheath body 1, the interior of the main valve body 2 is connected to the interior of the catheter sheath body 1, the interior of the main valve body 2 has an integrally structured funnel-shaped internal material guide cover 4, the outer side of the main valve body 2 is provided with a lateral receiving groove 5, and the lateral receiving groove 5 is movably fitted with a flip-close cover plate 6 and a drainage tube 7.

[0020] To facilitate connection, one end of the drainage pipe 7 is fixedly installed on the outer arc surface of the funnel-shaped inner guide cover 4, and the other end of the drainage pipe 7 is fixedly connected to the inner wall of the flip-closed cover plate 6.

[0021] By controlling the flip-closed cover plate 6 to flip outward, the drainage tube 7 is unfolded. By inserting the external guide tube into the opening on the outside of the drainage tube 7, the material can be guided into the catheter sheath body 1.

[0022] To facilitate lateral positioning, the outer side of the main valve body 2 has an integral lateral positioning block 21 located at the opening of the lateral receiving groove 5.

[0023] When the flip-closed cover 6 is flipped and inserted into the side storage slot 5, the flip-closed cover 6 is limited from the outside by the side limiting block 21.

[0024] To facilitate the outward movement of the flip-closed cover 6 in the closed state, the outer side of the main valve body 2 is provided with an arc-shaped operating groove 22 at the opening of the lateral storage groove 5 to facilitate the movement of the flip-closed cover 6.

[0025] To enhance the lateral support strength of the funnel-shaped internal material guide cover 4, a lateral isolation plate 8 is fixed between the main valve body 2 and the funnel-shaped internal material guide cover 4.

[0026] To ensure a tight closure after inward flipping, an inner locking frame 9 is fixed on the inner side of the flip-close cover plate 6.

[0027] After the flip-closed cover plate 6 flips inward, the inner locking frame 9 presses inward against the inner section of the drainage tube 7, thus closing and locking the drainage tube 7.

[0028] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
