技术领域technical field
本发明涉及医疗器械技术领域，特别涉及一种三通阀。The invention relates to the technical field of medical instruments, in particular to a three-way valve.
背景技术Background technique
三通阀一般与其它医疗器械配套使用，作为对病患的进行注射、输液、输血、检测或者抽血等用途，其在医疗领域的应用十分广泛。例如，在有创压力传感器中，在有创压力传感器的末端与病患之间设置有三通阀，如此，既能实现对病患提供持续性的动态检测，直接获得病患的血压的各项生理参数；又能通过三通阀采集病患的血液，避免对病患的多次刺穿而造成伤害，减轻病患的痛苦。但是，现有的三通阀的采血端都是通过一保护帽与阀体螺纹连接，以实现对采血口的密封。当需要进行采血时，要取下保护帽，而采血完成后，还需要拧紧保护帽，这种结构使采血操作较为麻烦，且保护帽还容易丢失，影响使用。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 the sealing of the blood collection port. When blood collection is required, the protective cap needs to be removed, and after the blood collection is completed, the protective cap needs to be tightened. This structure makes the blood collection operation more troublesome, and the protective cap is easy to lose, which affects the use.
