Description

Technical Field

[0001] This utility model relates to a catheter device, and more particularly to a catheter device for vascular interventional therapy. Background Technology

[0002] Interventional vascular therapy is a minimally invasive surgical technique that involves inserting a catheter into a blood vessel for diagnosis and treatment. It is widely used in the treatment of various vascular diseases, including arterial stenosis, thrombosis, aneurysms, and vascular malformations. The procedure requires inserting a catheter into the patient's body.

[0003] Patent CN 219355021 U discloses a catheter device for vascular interventional therapy. The device includes a fixing sleeve with multiple guide holes, and a guide post slidably connected within each guide hole. A guide block is fixedly connected to one outer wall of the guide post, and a fixing block is fixedly connected to the other outer wall. A support spring for supporting the push block is sleeved on the outside of the guide post. A rotating ring is rotatably connected to the outside of the fixing sleeve. This catheter device for vascular interventional therapy can effectively fix the position of the catheter body, preventing secondary injury to the patient due to accidental movement of the catheter body.

[0004] While the aforementioned technology can effectively fix the catheter left outside, the completely fixed catheter is restricted and makes it difficult for the patient to move. Even a slight movement can easily pull on the tube, making it impossible to move the catheter insertion site. Therefore, this technology has certain limitations. Hence, we have innovated this technology. Utility Model Content

[0005] The purpose of this invention is to provide a catheter device for vascular interventional therapy to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a catheter device for vascular interventional therapy, comprising a limiting ring, wherein telescopic tubes are fixedly connected to the top and bottom of the inner wall of the limiting ring, and fixed tubes are fixedly connected to the non-adjacent ends of the two telescopic tubes, wherein an opening is provided in the middle of the inner wall of the two fixed tubes, and extension rings are fixedly connected to the outer walls of the two fixed tubes, wherein multiple pressing blocks are fixedly connected to the adjacent ends of the two extension rings, pressure sensors are embedded in the top and bottom ends of the limiting ring, and an alarm is fixedly installed on the outer wall of the limiting ring.

[0007] As a preferred embodiment of the present invention, one of the pressure sensors is provided with a controller on one side, and the controller is embedded in a limiting ring.

[0008] In a preferred embodiment of this invention, the signal output terminals of both pressure sensors are electrically connected to the signal input terminal of the controller, and the signal output terminal of the controller is electrically connected to the signal input terminal of the pressure sensors.

[0009] As a preferred embodiment of this utility model, the two openings are of the same size, and the top ends of the two fixing tubes are symmetrically provided with multiple limiting strips, the multiple limiting strips being of the same size.

[0010] As a preferred technical solution of this utility model, a connecting plate is installed on the outer wall of the limiting ring, a U-shaped clamping plate is fixedly connected to one end of the connecting plate, a bolt is threaded to the top of the U-shaped clamping plate, and a pressing plate is rotatably connected to the bottom of the bolt through a set rotating shaft. The outer wall of the pressing plate is slidably connected to the inner wall of the U-shaped clamping plate.

[0011] As a preferred embodiment of this utility model, both the bottom end of the extrusion plate and the bottom end of the U-shaped card plate are fixedly connected with anti-slip pads, and the two anti-slip pads are of the same size.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, by connecting the catheter, a limiting ring, and a telescopic tube, and then using medical tape to wrap the limiting strip around the outer wall of the catheter to limit its position, ensures that the catheter remains in a fixed position outside the patient's body. The telescopic tube acts as a buffer against pulling at both ends of the catheter, preventing the insertion site from becoming completely immobile. Furthermore, a pressure sensor detects when the fixing tube is stretched, triggering an alarm to alert medical staff to severe catheter pulling, thus effectively improving the safety of the catheter when connected externally.

[0019] 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.

[0020] Example

[0021] Please see Figures 1-4 This utility model provides a technical solution:

[0022] The device includes a limiting ring 1, with telescopic tubes 2 fixedly connected to the top and bottom of the inner wall of the limiting ring 1. Fixed tubes 3 are fixedly connected to the non-adjacent ends of the two telescopic tubes 2. Openings 4 are opened in the middle of the inner walls of the two fixed tubes 3. Extension rings 6 are fixedly connected to the outer walls of the two fixed tubes 3. Multiple pressing blocks 7 are fixedly connected to the adjacent ends of the two extension rings 6. Pressure sensors 8 are embedded at the top and bottom of the limiting ring 1. An alarm 9 is fixedly installed on the outer wall of the limiting ring 1.

[0023] In this embodiment, a controller is provided on one side of one of the pressure sensors 8. The controller is embedded in the limiting ring 1. The signal output terminals of both pressure sensors 8 are electrically connected to the signal input terminals of the controller. When the conduit is pulled, it causes one set of telescopic tubes 2 to contract, which in turn causes one set of pressing blocks 7 to press between adjacent pressure sensors 8. After receiving the signal, the pressure sensor 8 transmits the signal to the alarm 9, thereby triggering the alarm 9 to sound an alarm and serve as a warning.

[0024] In this embodiment, the two openings 4 are of the same size, and the tops of the two fixed tubes 3 are symmetrically provided with multiple limiting strips 5. The multiple limiting strips 5 are of the same size. The limiting strips 5 themselves have a certain degree of flexibility and deformation ability. They can be wrapped around the outer wall of the conduit by moving the tape, thereby playing a role in limiting the conduit.

[0025] In this embodiment, a connecting plate 10 is installed on the outer wall of the limiting ring 1. A U-shaped clamping plate 11 is fixedly connected to one end of the connecting plate 10. A bolt 12 is threadedly connected to the top of the U-shaped clamping plate 11. A pressing plate 13 is rotatably connected to the bottom of the bolt 12 through a set rotating shaft. The outer wall of the pressing plate 13 is slidably connected to the inner wall of the U-shaped clamping plate 11. Anti-slip pads 14 are fixedly connected to the bottom of both the pressing plate 13 and the bottom of the U-shaped clamping plate 11. The two anti-slip pads 14 are the same size. By rotating the threaded bolt 12, the pressing plate 13 can be driven to descend, thereby adjusting the space inside the U-shaped clamping plate 11. This further provides the advantage of being applicable to beds of different sizes. In addition, the anti-slip pads 14 increase the friction between the device and the bed, thereby strengthening the stability of fixing the device to the bed.

[0026] Working principle: In use, the catheter is first inserted through the inner wall of the limiting ring 1 and the telescopic tube 2, and then through the opening 4. After the U-shaped clamping plate 11 is clamped to the edge of the bed, the threaded bolt 12 is rotated. With the cooperation of the rotating shaft, the squeezing plate 13 is driven to descend vertically, which further drives one of the anti-slip pads 14 to move closer to the other anti-slip pad 14, and clamps the edge of the bed in the U-shaped clamping plate 11 to fix the device. When fixing the catheter, medical tape can be used to wrap between the catheter and the limiting strip 5, so that the limiting strip 5 wraps around and limits the outer wall of the catheter. When the patient's insertion site moves slightly, the catheter is pulled. The movement of the catheter causes one of the telescopic tubes 2 to retract. When the pulling force is too great, the extension ring 6 drives the pressing block 7 to contact and press the pressure sensor 8 on the corresponding side, thereby triggering the alarm 9 to sound an alarm, so as to remind medical staff that the patient's catheter is being pulled too hard, thus facilitating timely treatment by medical staff.
