Abstract

The invention discloses a triple valve. The triple valve comprises a triple valve main body and a sealing rubber plug, wherein an accommodating cavity is formed in the triple valve main body; the triple valve main body is provided with a blood sampling end; a blood sampling opening which communicates with the accommodating cavity is formed in the blood sampling end; the sealing rubber plug is fixed to the blood sampling end and is used for sealing the blood sampling opening; the sealing rubber plug is also provided with an extruding gap; and when the blood sampling device is connected with theblood sampling end for blood sampling, the sealing rubber plug is extruded by the blood sampling device to enable the extruding gap to be opened and communicate with the blood sampling opening. The technical scheme of the triple valve disclosed by the invention aims to optimize the structure of the triple valve, and the operation of blood sampling is simplified through the triple valve.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a three-way valve. Background technique [0002] Three-way valves are generally used in conjunction with other medical devices for injection, infusion, blood transfusion, testing or blood drawing of patients, and are widely used in the medical field. For example, in the invasive pressure sensor, a three-way valve is set between the end of the invasive pressure sensor and the patient, so that continuous dynamic detection of the patient can be realized, and various parameters of the patient's blood pressure can be obtained directly. Physiological parameters; and the patient's blood can be collected through the three-way valve to avoid injury caused by multiple punctures to the patient and reduce the pain of the patient. However, the blood collection end of the existing three-way valve is threadedly connected to the valve body through a protective cap, so as to realize ...
