Fetal head vacuum suction deviceTechnical Field
The invention relates to the technical field of medical treatment, in particular to a fetal head vacuum suction device.
Background
The fetal head aspirator used by the obstetrician in early hospital during dystocia is connected with a rubber hose through a glass injector, and the negative pressure is generated in the fetal head aspirator by repeated extraction, which is generally completed by two or more persons in cooperation, which brings certain difficulty to work, and if the glass injector is not properly processed and is easy to break, unnecessary virus and bacterial infection is caused, and the generated negative pressure cannot reach an accurate negative pressure value because of no accurate measurement, so that the head of a fetus is easy to slide or be too tight when being pulled by the fetal head sucker, a certain danger is brought to the fetus, and the fetus is choked or dead when serious.
Along with the technical development, the palm negative pressure pump is invented, negative pressure suction is generated by manual pressing, the vacuum buoy is arranged, the negative pressure value range is distinguished through different colors on the vacuum buoy, the negative pressure value can be controlled by observing the color area on the vacuum buoy, the situation that the palm negative pressure pump is too tight and too loose is avoided, and compared with the early technology, the palm negative pressure pump is greatly improved.
However, the existing common head-up vacuum suction device in the market still has a plurality of inconveniences when in use, for example, when the device is inserted into a parent, people are required to manually pinch the suction disc to plug in, and negative pressure values are controlled in a manual reading mode, the negative pressure values are high, manual pressure release is needed, at the moment, the ultrahigh negative pressure has an influence on infants, the situation that the position of the fetal head is sucked cannot be observed in the traction process of the existing device, accidents of the position of the fetal head which is sucked cannot be known in time in some cases, the device can be detached after the traction work is ended, so that the situation that the fetal head cannot be known and treated at the first time when accidents occur is caused, and potential safety hazards exist.
