Description

Technical Field

[0001] This utility model relates to the field of arteriovenous puncture device technology, and in particular to a safe and efficient arteriovenous puncture device. Background Technology

[0002] Arterial and venous puncture needles are disposable medical devices consisting of an AVF needle tube, a rotatable core, an AVF rotatable protrusion, a clamp, an inner conical connector, a locking cap, and a blood collection tube. Arterial blood collection needles have a dorsal port, while venous blood collection needles do not; this design helps differentiate between and meet different clinical needs. Current safety-enhancing arterial and venous puncture devices typically involve inserting the needle tube into the blood vessel and then securing the needle and connecting tube to the arm with tape. Any excess connecting tube length is placed on the bed at the arm's position. However, when patients are asleep, slight arm movement may compress the excess connecting tube, potentially affecting blood circulation and treatment effectiveness. Utility Model Content

[0003] This invention provides a safer and more efficient arteriovenous puncture device, which solves the problems in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A safety-enhancing arteriovenous puncture device includes a connecting end disposed at one end of a connecting tube, a needle tube disposed at the other end of the connecting end, and pushers disposed on both sides of the connecting end. An installation block is connected to the surface of the connecting tube, and a strap is connected to one side of the installation block. A fixing block for receiving the connecting tube is installed on the surface of the strap. The surface of the fixing block is provided with a through hole, and one side of the fixing block is provided with a connecting groove that connects to the through hole.

[0005] As a further description of the above technical solution: The diameter of the connecting pipe is larger than the inner diameter of the connecting groove.

[0006] As a further description of the above technical solution: The surface of the connecting end is connected to a protective tube for protecting the needle tube.

[0007] As a further description of the above technical solution: The surface of the mounting block has a through groove, and the upper and lower parts of the through groove are respectively provided with positioning holes and mounting grooves. The top of the inside of the mounting groove is connected to a spring, and the bottom of the spring is connected to a fixing rod with a "T" shaped cross section. The surface of the strap has fixing holes that are equidistant from each other and are intended to contact the fixing rod.

[0008] As a further description of the above technical solution: The top end of the fixing rod is connected to a pull rod that is movably sleeved with the mounting block.

[0009] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: In this invention, the fixed block allows excess connecting tubes to be stored inside the through hole and fixed with tape. In addition, the strap, fixing hole, and fixing rod work together to fix the strap to the person's arm. This fixes the fixed block on the surface of the strap and the excess connecting tubes to one side of the arm, preventing excess connecting tubes from piling up on the bed and pressing on the connecting tubes when the arm moves slightly during sleep, thus affecting blood circulation and treatment effect.

[0012] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0013] Reference Figures 1-3A safety-enhancing arteriovenous puncture device includes a connecting end 2 at one end of a connecting tube 1, a needle tube 3 at the other end of the connecting end 2, and pushers 4 on both sides of the connecting end 2. A mounting block 5 is connected to the surface of the connecting tube 1, and a strap 6 is connected to one side of the mounting block 5. A fixing block 7 for receiving the connecting tube 1 is mounted on the surface of the strap 6. A through hole 14 is formed on the surface of the fixing block 7, and a connecting groove 15 connected to the through hole 14 is formed on one side of the fixing block 7. The device can be tied to the arm via the strap 6, and the fixing block 7 on the strap 6 can be positioned on one side of the arm, thereby allowing the connecting tube 1 to be deformed and moved through the connecting groove 15 to the penetrating artery. The inside of the perforation 14 is stored and fixed with tape, thus storing most of the excess connecting tube 1 and preventing it from piling up on the hospital bed, which could easily cause the arm to squeeze it, thereby affecting blood circulation and treatment effect. Of course, the surface of the connecting tube 1 is equally spaced with multiple mounting blocks 5, straps 6 and fixing blocks 7. The needle tube 3 is an ultra-thin-walled steel needle with a smooth puncture surface and tip design, which can effectively reduce pain and tissue damage. The pusher 4 is rotatable to adjust the puncture angle and puncture positioning, which can help doctors quickly and accurately find the blood vessel location. Different colors or model markings help to quickly identify and select the appropriate specifications.

[0014] Furthermore, the diameter of the connecting pipe 1 is larger than the inner diameter of the connecting groove 15. Since the connecting pipe 1 can deform, the deformed connecting pipe 1 can be moved through the connecting groove 15 into the through hole 14 for storage, and the connecting pipe 1 can be fixed by tape or the like.

[0015] Furthermore, the surface of the connecting end 2 is connected to a protective tube 17 for protecting the needle tube 3. The protective tube 17 is a corrugated tube that is retractable. It is designed to protect the exposed needle tube 3 from dust and other contaminants after the front end of the needle tube 3 is inserted into the blood vessel.

[0016] Furthermore, the surface of the mounting block 5 is provided with a through groove 8, and the upper and lower parts of the through groove 8 are respectively provided with positioning holes 9 and mounting grooves 10. The top of the inside of the mounting groove 10 is connected to a spring 11, and the bottom of the spring 11 is connected to a fixing rod 12 with a "T" shaped cross section. The surface of the strap 6 is provided with fixing holes 16 that are equidistant from the fixing rod 12, which facilitates the strap 6 to be passed through the through groove 8 and tied to the arm. With the action of the spring 11, the fixing rod 12 can be moved downward, so that the fixing rod 12 passes through the fixing holes 16 on the strap 6 and connects with the positioning holes 9, thereby tying the strap 6 to the arm.

[0017] Furthermore, the top end of the fixing rod 12 is connected to a pull rod 13 that is movably sleeved with the mounting block 5, which facilitates the removal of the fixing rod 12 from the inside of the fixing hole 16 by pulling the pull rod 13.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
