Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a nephrology dialysis catheter stent. Background Technology

[0002] A dialysis catheter stent is a medical device used to support and secure long-term dialysis catheters. These stents are typically made of biocompatible materials and can be placed under the skin to ensure the catheter remains stable, reduce catheter movement and skin irritation, thereby improving the patient's quality of life. They are used for long-term hemodialysis patients who require regular hemodialysis treatment to sustain their lives.

[0003] Existing nephrology dialysis catheter stents use a cannula to bind the inflow and outflow channels together, and then attach it to the skin with a patch for fixation. Blood is filtered through a dialysis machine. Because the inflow and outflow channels are bound together, they become fused together. When connected to the dialysis machine, either the inflow or outflow channel can obstruct the connection, making it difficult to connect. Furthermore, the placement of the inflow or outflow channel can affect the progress of the surgery. Therefore, a new type of nephrology dialysis catheter stent has been proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a nephrology dialysis catheter stent that is easy to connect to a dialysis machine.

[0005] To achieve the aforementioned goal of facilitating connection with a dialysis machine, this utility model provides the following technical solution: a nephrology dialysis catheter support, comprising a base, a sleeve seat fixedly connected to the top of the base, a sleeve fixedly connected to the inner wall of the sleeve seat, an inflow tube provided on the inner wall of the sleeve, and an outflow tube provided on the inner wall of the sleeve and outside the inflow tube, and an opening component provided on the base, the inflow tube and the outflow tube for facilitating connection with a dialysis machine for blood filtration.

[0006] Furthermore, the spreading assembly includes a threaded rod, a movable seat, a lower connecting seat, a connecting rod, and an upper connecting seat. The threaded rod is rotatably connected to the side wall of the base. The movable seat is threadedly connected to the outer surface of the threaded rod. The lower connecting seat is wrapped around the bottom of the inlet pipe and the outlet pipe. The connecting rod is hinged between the movable seat and the lower connecting seat on opposite sides. The upper connecting seat is wrapped around the top of the inlet pipe and the outlet pipe and is combined with the lower connecting seat.

[0007] Furthermore, the inflow pipe and the outflow pipe are fixed to each other, and the lower connecting seat and the upper connecting seat are both fan-shaped, and the lower connecting seat and the upper connecting seat are adapted to the side close to the inflow pipe and the outflow pipe.

[0008] Furthermore, a connecting screw that is threadedly connected to the lower connecting seat is inserted through the upper connecting seat, a handle is fixedly installed at the head of the threaded rod, and a guide rod that is slidably connected to the movable seat is fixedly connected to the side wall of the base.

[0009] Furthermore, both the inlet and outlet pipes are connected to plugs at their ends, the base has a membrane at its tail, and the sidewalls of the membrane are connected to lugs.

[0010] Compared with the prior art, this utility model provides a nephrology dialysis catheter stent with the following features:

[0011] Beneficial effects:

[0012] This nephrology dialysis catheter stent, through the inclusion of an opening component, moves the movable seat by rotating the threaded rod. The connection between the connecting rod, the movable seat, and the lower connecting seat allows the movement of the movable seat to open the inflow and outflow tubes on the lower connecting seat, making them face forward and backward respectively. This facilitates docking with the dialysis machine for hemodialysis filtration and avoids obstruction caused by one of the inflow or outflow tubes being docked with the dialysis machine.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-2A nephrology dialysis catheter stent includes a base 1, a sleeve seat 2 fixedly connected to the top of the base 1, a sleeve 3 fixedly connected to the inner wall of the sleeve seat 2, an inlet tube 4 provided on the inner wall of the sleeve 3, and an outlet tube 5 provided on the inner wall of the sleeve 3 and outside the inlet tube 4. Blood is filtered through a dialysis machine, and blood can be injected into or drained from the inlet tube 4 and the outlet tube 5, respectively. The inlet tube 4 and the outlet tube 5 are fixed to each other, and each end of the inlet tube 4 and the outlet tube 5 is connected to a plug 9 for insertion into the subcutaneous tissue.

[0018] The base 1 has a mucosa 10 at its tail end, which is convenient for fixing to the skin. The side wall of the mucosa 10 is connected to a lug 11, which makes it easy to tear the mucosa 10 apart.

[0019] Please see Figure 1-2 The base 1, inlet pipe 4, and outlet pipe 5 are equipped with a support assembly 6 for easy connection to a dialysis machine for blood filtration. The support assembly 6 includes a threaded rod 61, a movable seat 62, a lower connecting seat 63, a connecting rod 64, and an upper connecting seat 65. The threaded rod 61 is rotatably connected to the side wall of the base 1. A handle 7 is fixedly installed at the head of the threaded rod 61 to facilitate rotation of the threaded rod 61. The movable seat 62 is threadedly connected to the outer surface of the threaded rod 61. Rotation of the threaded rod 61 can drive the movable seat 62 to move. A guide rod 8 is fixedly connected to the side wall of the base 1 and slidably connected to the movable seat 62 to guide and support the movable seat 62, so that the movable seat 62 can only move and will not rotate.

[0020] Furthermore, the lower connecting seat 63 is wrapped around the inflow tube 4 and the outflow tube 5 below. The connecting rod 64 is hinged between the movable seat 62 and the lower connecting seat 63 on opposite sides. With the connection of the connecting rod 64, the movable seat 62 can push the inflow tube 4 and the outflow tube 5 on the lower connecting seat 63 to bend outwards respectively, so that the dialysis machine tubing can be easily connected to the inflow tube 4 or the outflow tube 5, and also reduce the obstruction of the inflow tube 4 or the outflow tube 5 by the patient's body, thus improving the patient's comfort.

[0021] Meanwhile, the upper connecting seat 65 wraps around the inflow pipe 4 and the outflow pipe 5 and is combined with the lower connecting seat 63, which can hold the inflow pipe 4 and the outflow pipe 5 in place, allowing the inflow pipe 4 and the outflow pipe 5 to open on their own. Both the lower connecting seat 63 and the upper connecting seat 65 are fan-shaped and are adapted to each other on the side close to the inflow pipe 4 and the outflow pipe 5. A connecting screw that is threaded onto the upper connecting seat 65 and connected to the lower connecting seat 63 is inserted thereon to connect the lower connecting seat 63 and the upper connecting seat 65.

[0022] In this embodiment, when the handle 7 is turned, the threaded rod 61 drives the movable seat 62 to move. With the connection of the connecting rod 64 to the movable seat 62 and the lower connecting seat 63, the lower connecting seat 63 drives the inflow tube 4 and the outflow tube 5 to separate from each other, so that the dialysis machine can be connected to the inflow tube 4 or the outflow tube 5 for hemodialysis.

[0023] The beneficial effects of the above embodiments are as follows:

[0024] This nephrology dialysis catheter stent, through the setting of the opening component 6, after the opening component 6 is used, the rotation of the threaded rod 61 drives the movable seat 62 to move. With the connection of the connecting rod 64 with the movable seat 62 and the lower connecting seat 63, the movement of the movable seat 62 can push the inflow tube 4 and the outflow tube 5 on the lower connecting seat 63 to open up to each other, so that the inflow tube 4 and the outflow tube 5 face forward and backward respectively, which facilitates docking with the dialysis machine for hemodialysis filtration and avoids the obstruction caused by one of the inflow tube 4 and the outflow tube 5 docking with the dialysis machine.
