2）输液初始时，将斜置排气针头10在靠近医用压力传感器9的触头上部处插入输液管8中，这时，在通大气管2所提供的大气压力作用下，通过竖立针头7，输液管8中的液柱向下流动，当斜置排气针头10开始流出药液并持续2-3秒钟后，将斜置排气针头10从输液管8中拔下，输液管8中的药液不会再向外流，而医用压力传感器9的触头可以检测到吊瓶3及输液管中药液的压力变化。2) At the beginning of infusion, insert the oblique exhaust needle 10 into the infusion tube 8 at the upper part of the contact close to the medical pressure sensor 9. , the liquid column in the infusion tube 8 flows downward, when the oblique exhaust needle 10 starts to flow out the liquid medicine and lasts for 2-3 seconds, pull the oblique exhaust needle 10 from the infusion tube 8, and the infusion tube 8 The medicinal liquid in the bottle will not flow out again, and the contact of the medical pressure sensor 9 can detect the pressure change of the medicinal liquid in the hanging bottle 3 and the infusion tube.
本实用新型的有益效果是，一种用于输液自动报警的压力传感装置，与控制装置和语音报警装置共同构成输液自动报警装置；压力传感装置是由竖立针头、输液管、医用压力传感器和斜置排气针头组成，竖立针头插入吊瓶橡胶盖，输液管上部与竖立针头连接，输液管下部与医用压力传感器连接，医用压力传感器与控制装置相连接；输液过程中，吊瓶中液体通过竖立针头、输液管形成液柱对医用压力传感器产生静压力，压力传感器向控制装置传送压力变化的信息，当药液逐渐减少，吊瓶中液体的重力小于控制装置中预置的报警压力时，控制装置控制语音报警装置发出报警语音。The beneficial effect of the utility model is that a pressure sensing device for automatic alarming of infusion constitutes an automatic alarming device for infusion together with a control device and a voice alarm device; the pressure sensing device is composed of a vertical needle, an infusion tube, a medical pressure sensor Composed of an oblique exhaust needle, the vertical needle is inserted into the rubber cap of the hanging bottle, the upper part of the infusion tube is connected to the vertical needle, the lower part of the infusion tube is connected to the medical pressure sensor, and the medical pressure sensor is connected to the control device; during the infusion process, the liquid in the hanging bottle The liquid column formed by erecting needles and infusion tubes generates static pressure on the medical pressure sensor, and the pressure sensor transmits pressure change information to the control device. When the liquid medicine gradually decreases and the gravity of the liquid in the hanging bottle is lower than the preset alarm pressure in the control device , the control device controls the voice alarm device to send out an alarm voice.
很显然，上述实施例只是为了说明本实用新型所列举的实例，任何本领域内普通的技术人员的简单更改和替换都是本实用新型的保护之内。Apparently, the above-mentioned embodiments are only for illustrating examples of the utility model, and any simple modifications and replacements by those skilled in the art are within the protection of the utility model.
