Infection-free puncture needle

Abstract

The invention provides an infection-free puncture needle. The infection-free puncture needle is provided with a puncture needle head; the puncture needle head is of a symmetrical double-cavity structure, the upper cavity is a liquid suction channel, and the lower cavity is a liquid outlet channel; the liquid suction channel is connected with a liquid suction needle base, and the liquid outlet channel is connected with a liquid outlet needle base; the liquid suction needle base is connected with a liquid suction syringe, and the liquid outlet needle base is connected with a liquid outlet syringe; a liquid suction piston rod is arranged in the liquid suction syringe, a liquid outlet piston rod is arranged in the liquid outlet syringe, and symmetrical wings are arranged at the upper portion of the tail end of the liquid suction syringe and the lower portion of the tail end of the liquid outlet syringe. According to the infection-free puncture needle, liquid suction and medicine liquid injection can be conducted in different channels of the same puncture needle head respectively, and thus cross infection is avoided.

Description

technical field [0001] The invention belongs to the technical field of medical supplies, in particular to an infection-free puncture needle. Background technique [0002] Pericardiocentesis is a diagnosis and treatment technique that directly penetrates the pericardial cavity with the help of a puncture needle. Its purpose is to drain the effusion in the pericardial cavity and reduce the intrapericardial pressure. It is a first-aid measure for acute pericardial effusion; the pericardial effusion is extracted through puncture for biochemical determination, and smears are used to find bacteria and pathological cells. Bacterial culture is used to differentially diagnose pericardial diseases of various natures; pericardiocentesis, injection of antibiotics and other drugs, and treatment are carried out. However, the current puncture needles are ordinary puncture needles, most of which have only one lumen. After successfully extracting the effusion under the guidance of B-ultraso...

Problems solved by technology

However, the current puncture needles are ordinary puncture needles, most of which have only one lumen. After successfully extracting the effusion under the guidance of B-ultrasound, the drug needs to be delivered to the patient's body through the liquid aspiration needle, so the use of single-lumen needles is not suitable. Hygienic standards for medical infection prevention, so there is a need to improve
