Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a hemostatic device for tunnel-type PICC catheterization. Background Art

[0002] PICC placement, short for peripherally inserted central catheterization, involves inserting a catheter into a vein in the arm. The catheter reaches directly into a large vein near the heart, preventing direct contact between chemotherapy drugs and the arm vein. The rapid blood flow in large veins can quickly dilute chemotherapy drugs and prevent them from irritating the blood vessels. Therefore, it can effectively protect upper limb veins, reduce the incidence of phlebitis, alleviate pain, and improve patients' quality of life. Before performing an intravenous catheterization procedure, a tourniquet is first used to bind the patient's arm to stop bleeding, allowing medical staff to perform the elbow puncture and catheterization procedure.

[0003] Traditional tourniquets are mostly tied together, requiring medical staff to exert considerable effort to tie the catheter. Furthermore, the effectiveness of the tie varies from patient to patient, impacting the safety of the surgical procedure. After the catheter is inserted into the patient, 10-15 cm of the catheter needs to be left outside the patient's body for subsequent use. To minimize the impact of the extended catheter on the patient's movements and prevent discomfort caused by swaying, medical staff often use tape to attach the catheter to the patient's body surface. However, the tape can easily become ineffective if the patient sweats or after being attached for a period of time, affecting the stability of the fixation. Therefore, those skilled in the art have provided a hemostatic device for tunneled PICC catheterization to address the problems raised in the aforementioned background technology.
