Description

Technical Field

[0001] The utility model relates to the technical field of puncture needle protection, in particular to a protection device for a femoral artery puncture needle. Background Art

[0002] The femoral artery puncture needle is a medical device used for femoral artery puncture, which is a process of inserting a catheter into the femoral artery for cardiac catheterization, coronary angiography, interventional therapy, etc. The femoral artery is a major artery located on the inner side of the thigh that supplies blood to the thigh muscles and bones. Puncturing the femoral artery provides access to the vascular system, allowing medical staff to perform necessary examinations and treatments.

[0003] During the femoral artery puncture process, a femoral artery puncture needle is needed to puncture the femoral artery and insert a catheter. The operator stands on one side of the patient and feels the blood vessel pulsation with the index finger or middle finger. With the other hand, hold a syringe or puncture needle connected to the needle and insert it into the femoral artery at an angle of 30° to 40° against the direction of blood flow. When blood spurts out, slowly advance another 0.3 to 0.5 cm to prevent it from falling out.

[0004] The currently available femoral artery puncture needle does not protect the needle after the puncture is completed, which poses certain risks and may cause secondary injury or contamination. At the same time, the angle cannot be limited and measured during the puncture. Utility Model Content

[0005] The purpose of the utility model is to provide a protective device for a femoral artery puncture needle to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A protective device for a femoral artery puncture needle comprises a needle tube, one end of the needle tube is provided with a connector, one end of the connector is adapted to be provided with a needle, winding devices are fixedly provided on both sides of the connector, a telescopic wire is adapted to be provided on the surface of the winding device, a protective cap is fixedly provided at one end of the telescopic wire, and one side of the connector is adapted to be provided with an angler.

[0008] Furthermore, a connecting plate is fixedly provided on one side of the connector, a connecting groove is opened on one side of the connecting plate, and a connecting rod is embedded in the connecting groove.

[0009] Furthermore, the winding device includes a winding plate symmetrically installed on both sides of the connector, a winding ring is provided at one end of the winding plate, a return spring is provided on the surface of the winding ring, and the surface of the winding ring is fixedly connected to one end of the telescopic line.

[0010] Further, the protective cap is adapted to the needle.

[0011] Furthermore, the angler includes an angle shaft embedded in the surface of the connecting rod, an angle ring is adapted to be provided on the surface of the angle shaft, an angle groove is opened on one side of the angle ring, the angle groove is adapted to the angle shaft, and an angle pad is fixed to one end of the angle ring.

[0012] Furthermore, one side of the angle ring is adapted to be provided with a scale.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) In order to prevent the protective cap from affecting the use of the needle during use and to prevent the protective cap from falling off when protecting the needle, winding devices are symmetrically provided on both sides of the connector. When the needle needs to be protected after puncture, the protective cap is pulled so that the protective cap drives the telescopic wire to move, and the telescopic wire drives the winding ring to rotate, and applies tension to the reset spring on the surface of the winding ring to deform the reset spring. The reset spring drives the winding ring to reset through the elastic restoring force generated by the reset, and generates tension on the telescopic wire, so that the telescopic wire generates tension on the protective cap, ensuring that the protective cap is firmly mounted on the surface of the needle. When not in use, the elastic restoring force of the reset spring drives the winding ring to rotate, and the telescopic wire is wound up, so that the telescopic wire drives the protective cap to move, thereby reducing the impact on the needle during use.

[0015] (2) In order to facilitate the angle adjustment of the puncture needle and ensure the accuracy of the angle during use, an angle gauge is fixed on one side of the connector. When in use, the connector is connected to the angle gauge by inserting the connecting rod into the angle shaft, and the angle pad is brought into contact with the patient's skin. The needle tube is adjusted so that the connecting rod drives the angle shaft to adjust the angle in the angle groove so that the needle tip is between 30° and 40° to the patient's skin. After the adjustment is completed, the needle tube is pushed so that the needle tube and the needle tip move back and forth according to the connecting groove to complete the puncture work of the puncture needle.
