Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical appliances, in particular to a blood vessel bypass tube convenient for drug injection. Background Art
[0002] Limb blood vessel trauma is a common trauma, which is relatively common both in daily sudden events such as car accidents and industrial injuries and on the battlefield during wartime. At present, the main methods for dealing with limb blood vessel trauma are compression hemostasis, ligation hemostasis, and vascular anastomosis, etc. Among them, rescue measures such as compression hemostasis and ligation hemostasis need to be carried out in a hurry, and their purpose is to control bleeding and save lives. For the injuries of some important blood vessels such as carotid artery, iliac artery, and femoral artery, if only compression hemostasis and ligation hemostasis are given and vascular anastomosis cannot be carried out in time to restore blood supply, it will reduce the blood supply to the distal end of the limb, and even lead to serious consequences such as amputation, cerebral infarction, and death. Vascular anastomosis surgery is the preferred treatment plan after blood vessel injury, but it must have conditions such as sufficient time, good anesthesia, perfect instruments, and high surgical techniques. Therefore, before the limb blood vessel trauma occurs and the wounded are transferred to the hospital for vascular anastomosis surgery, it is necessary to maintain limb blood supply. Or when performing some arterial surgeries (such as carotid endarterectomy), it is necessary to cut open the blood vessel and block the blood flow. When the blood flow is blocked for a certain period of time, it will cause great damage to the patient. A blood vessel bypass tube is a medical device used to keep blood flow unobstructed in critical situations. Its main function is to establish blood vessel bypass during surgery and perform surgery on the premise of ensuring unobstructed blood flow at the distal end of the limb. When using a blood vessel bypass tube, heparin sodium and anticoagulants need to be injected into it. However, the existing blood vessel bypass tube has a relatively simple structure, is not convenient for drug injection, and the existing blood bypass tube cannot adjust the blood flow rate, and its applicability is poor. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is to overcome the above-mentioned technical defects and provide a blood vessel bypass tube convenient for drug injection.
[0004] To solve the above technical problem, the technical solution provided by the utility model is a blood vessel bypass tube convenient for drug injection: including a first tube body and a second tube body;

BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 It is a schematic structural diagram of a blood vessel bypass tube for convenient drug injection of the present utility model.
[0010] As shown in the figure:
[0011] 1. First tube body, 2. Second tube body, 3. First medical three-way cock, 4. Connecting tube, 5. First plug cap, 6. Second plug cap, 7. Second medical three-way cock. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0012] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Usually, the components of the embodiments of the present utility model described and illustrated herein can be arranged and designed in various different configurations.
[0013] Embodiment 1, in combination with the attached Figure 1 , a blood vessel bypass tube for convenient drug injection, including a first tube body 1 and a second tube body 2;
