Puncturing device for deep vein catheterization

Abstract

The invention discloses a puncture device for deep vein catheterization, which comprises a puncture fixing device and a puncture needle. Needle, the bottom end of the syringe connector is located on the outer wall of the puncture needle and is sleeved with a push block, through the puncture fixing device, it is convenient for the doctor to use the puncture to puncture the patient, and the angle of the puncture needle can be adjusted by adjusting the angle of the puncture fixing device , so as to ensure the puncture angle of the puncture needle when using the subclavian vein puncture method and the internal jugular vein puncture method, and avoid accidentally injuring other blood vessels of the patient when the puncture needle is used for puncture. It can control the penetration speed of the puncture needle, and can also control the puncture needle to complete the needle return, which reduces the labor intensity of the doctor and makes the puncture go smoothly.

Description

technical field [0001] The invention relates to the technical field of venous catheterization, in particular to a puncture device for deep vein catheterization. Background technique [0002] The technique of deep vein catheterization is widely used clinically because it is simple and convenient to operate and does not require special equipment. It is usually used for the following types of patients: 1. critically ill patients such as severe trauma, shock, and acute circulatory failure; For patients treated with infusion or intravenous antibiotics, 3. patients who need total parenteral nutrition, 4. patients who need to receive a large amount of fast blood transfusion and fluid replacement, the measurement of central venous pressure can be used to adjust the input volume and speed at any time. In the operation of deep vein catheterization, two puncture methods are commonly used at present, one is the subclavian vein puncture method, and the other is the internal jugular vein ...

[0002] The technique of deep vein catheterization is widely used clinically because it is simple and convenient to operate and does not require special equipment. It is usually used for the following types of patients: 1. critically ill patients such as severe trauma, shock, and acute circulatory failure; For patients treated with infusion or intravenous antibiotics, 3. patients who need total parenteral nutrition, 4. patients who need to receive a large amount of fast blood transfusion and fluid replacement, the measurement of central venous pressure can be used to adjust the input volume and speed at any time. In the operation of deep vein catheterization, two puncture methods are commonly used at present, one is the subclavian vein puncture method, and the other is the internal jugular vein puncture method, but these two puncture methods are currently being used to treat patients. When puncturing, it is necessary to control the puncture position and the included angle of the puncture needle, otherwise it is easy to cause inaccurate puncture position of the puncture needle during the puncture process, resulting in the puncture of the patient's artery or other blood vessels, and failure to complete the treatment. It will increase the pain of the patient. At the same time, when performing puncture, the puncture needle needs to be needled back, which will not only increase the labor intensity of the operating doctor, but also make it difficult to grasp the puncture speed of the puncture needle. Therefore, we propose a Puncture device for deep vein catheterization
