Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a deep vein puncture tube with a hemostatic device. Background Art

[0002] At present, the deep vein puncture kit used clinically is composed of a syringe, a special puncture needle, a guide wire, a deep outer needle, a suture, a skin suture needle and a scalpel. To complete a deep vein puncture, it is necessary to go through the following steps: ① disinfection, ② laying a sterile towel, ③ trying to penetrate the deep vein with the inner needle, ④ puncturing with a thick puncture needle, ⑤ inserting a guide wire from the hollow tail of the syringe or the opening of the thick puncture needle after the thick puncture needle has drawn back a large amount of venous blood, ⑥ withdrawing the puncture needle, inserting a deep vein catheter along the guide wire, ⑦ suturing the skin, bandaging, etc. There are the following technical defects: 1. There is no better way to stop bleeding after the insertion of the intravenous catheter. Bleeding after the deep vein catheter is inserted will cause greater damage to the tissues around the deep vein. If it is accidentally inserted into the artery, it can cause local hematoma or even massive bleeding that endangers life; 2. The deep vein catheter can only be fixed externally, and there is no internal fixation solution.

[0003] Therefore, how to design a deep vein puncture tube with a hemostatic device has become an urgent problem to be solved. Utility Model Content

[0004] In view of the problems existing in the prior art, the utility model provides a deep vein puncture tube with a hemostatic device to solve at least one of the above technical problems.

[0005] The technical solution of the utility model is: a deep vein puncture tube with a hemostatic device, comprising a Y-shaped catheter, the closed end of the Y-shaped catheter is fixedly connected to a hemostatic sheath, the outer ring of the hemostatic sheath near the open end of the Y-shaped catheter is provided with an airplane wing, at least one balloon is provided between the hemostatic sheath and the airplane wing, pipelines are provided in the hemostatic sheath to respectively connect the balloon and an inflation device, the inflation device comprises a trachea, one end of the trachea is connected to an inflation ball, and the other end of the trachea is connected to the pipeline; the two open ends of the Y-shaped catheter are respectively connected to infusion connectors.

[0006] The utility model adopts a closed end of a Y-shaped catheter and a hemostatic sheath for fixed connection, and a balloon structure is provided. For patients with coagulation dysfunction and patients with deep vein catheter bleeding after puncture, the purpose of hemostasis can be achieved by inserting a hemostatic sheath and inflating a balloon, and the airplane wing plays a fixing role. For the femoral vein and clavicular vein (the puncture needle entry point is far from the vascular puncture point), internal fixation can be achieved by inflating the balloon, and there is no need to fix the airplane wing. It can be fixed by applying a transparent dressing on the outside in combination with the balloon internal fixation. BRIEF DESCRIPTION OF THE DRAWINGS
