Description

Technical Field

[0001] This utility model relates to the field of puncture catheter technology, specifically a puncture catheter. Background Technology

[0002] A puncture catheter is a medical tool used to enter blood vessels, body cavities, or tissues in the human body for diagnosis, treatment, or monitoring.

[0003] A search revealed a patent, CN220530093U, which discloses a puncture catheter. The catheter includes a skin protective pad with plastic fixing plates at both ends of one side. Each plastic fixing plate has a plastic fixing element at its upper end. A connecting piece is located at the upper end of one side of the plastic fixing element, and an arc-shaped support piece is located at the lower end of the connecting piece. A first conduit is located below the arc-shaped support piece, and a second conduit is located at the end of the skin protective pad furthest from the first conduit. This invention has a simple and reasonable structure, improving the stability of the puncture catheter and preventing it from loosening or falling out due to patient sweating or movement, thus reducing patient discomfort.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative documents use springs and arc-shaped clamping sleeves to hold and fix the puncture catheter. However, in reality, the tip of the puncture catheter needs to be inserted into the human body at a certain angle, and the angle varies from person to person. In the aforementioned comparative documents, the angle of the arc-shaped clamping sleeve after clamping the puncture catheter is difficult to change. If it is necessary to tilt the puncture catheter to match the angle, the skin protection pad fixed to the patient's skin needs to be removed, and the fixation position needs to be readjusted before fixing, which reduces the efficiency of puncture. Therefore, there is an urgent need in the art to improve the puncture catheter to overcome the shortcomings of the prior art. Utility Model Content

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.

[0028] Please see Figures 1-6 A puncture catheter includes a rear connecting catheter 1 and a front puncture catheter 2. A rigid catheter 3 is fixedly connected between the rear connecting catheter 1 and the front puncture catheter 2. Two symmetrical clamping plates 4 are provided on the side of the rigid catheter 3 for clamping and fixing the rigid catheter 3. A connecting part 5 with a gap between it and the side of the rigid catheter 3 is provided below the rigid catheter 3. The connecting part 5 is used to connect to the patient's skin. Two fixing plates 6 are provided on the upper part of the connecting part 5, located on opposite sides of the rigid catheter 3. Movable seats 7 are provided on opposite sides of the two fixing plates 6. Rotating grooves 8 are opened on opposite sides of the two movable seats 7. Rotating balls 9 are rotatably connected in the rotating grooves 8. The rotating balls 9 are fixedly connected to one side of the clamping plates 4.

[0029] Specifically, when a patient needs to be punctured, the puncture site is determined, and the connecting part 5 is fixed to the side of the puncture site with tape or adhesive. Two clamping plates 4 are used to hold the rigid catheter 3 in place. The rigid catheter 3 is made of a hard material, and after the two clamping plates 4 are clamped to the side of the rigid catheter 3, the rigid catheter 3 is not easily deformed. The rotating ball 9 can rotate within the rotating groove 8, and there is a gap between the rigid catheter 3 and the connecting part 5. When it is necessary to adjust the angle of the front puncture catheter 2, the angle of the clamping plate 4 can be changed by rotating the rigid catheter 3. When it is necessary to adjust the angle of the front puncture catheter 2, it is not necessary to remove the connecting part 5, thereby improving the efficiency of puncture.

[0030] As a technical optimization of this utility model, a movable column 10 is passed through the fixed plate 6, and one side of the movable seat 7 is connected to one end of the movable column 10. A pull plate 11 is fixedly connected to the end of the movable column 10 away from the movable seat 7. An elastic element 12 with elasticity is provided on one side of the fixed plate 6 and the movable seat 7. The elastic element 12 is sleeved on the side of the movable column 10. A positioning bolt 13 is threadedly connected to the side of the movable seat 7. One end of the positioning bolt 13 abuts against the side of the rotating ball 9.

[0031] Specifically, when it is necessary to clamp and fix the rigid conduit 3, pull the two pull plates 11 in opposite directions. The two pull plates 11 drive the moving column 10 to move in opposite directions. At this time, the elastic element 12 is compressed. The elastic element 12 is specifically a spring. The two clamping plates 4 move in opposite directions. The rigid conduit 3 is placed between the two clamping plates 4. Release the pull plates 11. At this time, the tension of the elastic element 12 pushes the clamping plates 4 to move. The two clamping plates 4 clamp and fix the rigid conduit 3. The distance between the two clamping plates 4 can be adjusted for clamping and fixing. In this way, it is possible to clamp and fix rigid conduits 3 of different sizes, thereby improving the applicability of the overall device. When it is necessary to fix the angle position of the rigid conduit 3, the positioning bolt 13 is locked. One end of the positioning bolt 13 is tightly pressed against the side of the rotating ball 9, thereby fixing the angle of the rigid conduit 3.

[0032] As a technical optimization of this utility model, elastic pads 14 are provided on the opposing sides of the two clamping plates 4. The elastic pads 14 are elastic. A plug strip 15 is fixedly connected to the side of the elastic pad 14 near the clamping plate 4. A plug groove 16 adapted to the plug strip 15 is opened on the side of the clamping plate 4. A limiting bolt 17 with one end abutting against the side of the plug strip 15 is threadedly connected to the side of the clamping plate 4 away from the elastic pad 14.

[0033] Specifically, by setting up elastic pads 14, it is possible to clamp and fix rigid conduits 3 of different sizes without damaging the side of the rigid conduits 3. If it is necessary to clamp and fix rigid conduits 3 of different sizes, elastic pads 14 of different sizes are installed, the plug strip 15 on one side of the elastic pad 14 is inserted into the plug groove 16, and then the limiting bolt 17 is locked. One end of the limiting bolt 17 abuts against the side of the plug strip 15 to limit and fix the plug strip 15, thereby expanding the applicable range of clamping and fixing rigid conduits 3 of different sizes.

[0034] As a technical optimization of this utility model, both ends of the connecting part 5 are provided with straps 18. The straps 18 are elastic and their ends are provided with matching Velcro. Several hanging posts 19 are fixedly connected to the upper part of both ends of the connecting part 5. Anti-drop ball 20 is fixedly connected to the upper end of each hanging post 19. One side of one end of the strap 18 is provided with a through hole 21 and a moving card interface 22 that are interconnected. The through hole 21 is adapted to the anti-drop ball 20, and the moving card interface 22 is adapted to the hanging post 19.

[0035] Specifically, if puncture is required in the patient's leg or arm, the Velcro at both ends of the strap 18 can be used to fasten the strap 18 to the side of the leg or arm, improving the stability of the overall device after installation. When the strap 18 is needed, the through-hole 21 at one end of the strap 18 is fitted onto the anti-drop ball 20. After the through-hole 21 is fitted onto the side of the hanging post 19, the strap 18 is pulled away from the connecting part 5. The movable card interface 22 slides on the side of the hanging post 19. The hanging post 19 is located on the side of the movable card interface 22, and the strap 18 is hung on the side of the strap 18 in conjunction with the anti-drop ball 20. The two straps 18 are tightened again to fix them, improving the applicability of the overall device.
