therefore, by continuously operating the gas pressure control cabinet 4, the gas in the high-pressure chamber in the inner cavity of the gas pressure control cabinet 4 enters the inner cavity of the gas cavity 825 through the connecting pipe 824, so that the pressure in the inner cavity of the gas cavity 825 is increased, the second concave ring 822 moves upwards, the fourth pulley 831 and the third pulley 96 are driven to synchronously move, at the moment, the high-damping rubber ring 812 is separated from the inner surface of the first connecting hole 961 and enters the inner cavity of the second connecting hole 832 to be connected with the fourth pulley 831, the second motor 81 can drive the fourth pulley 831 to rotate, and the medical silica gel sucker 11 can move left and right;

on the contrary, by operating the gas pressure control cabinet 4, the high pressure chamber is closed, the low pressure chamber is opened, the air in the inner cavity of the air chamber 825 is pumped out through another connecting pipe 824 to generate negative pressure, and then the pulley 831 and the pulley 96 are dragged to move downwards, so that the inner cavity of the high damping rubber ring 812 is separated from the inner cavity of the connecting hole 832, enters the inner cavity of the connecting hole 961, and drives the adjusting mechanism two 9, and then the front and back positions of the medical silica gel sucker 11 can be adjusted, and under the cooperation of the gas pressure control cabinet 4, the electric control valve between the low pressure chamber and the medical silica gel sucker 11 is opened, the electric control valve between the inner cavity of the air chamber 825 and the low pressure chamber is closed, so that the external air enters the low pressure chamber through the medical silica gel sucker 11, and then the head of the newborn can be adsorbed and pumped out backwards, and finally the midwife and the like are completed under the cooperation of the midwife and the like.

It should be noted that the specific installation method, the circuit connection method and the control method of the gas pressure control cabinet 4, the first motor 66, the second motor 81, the second pulley 95, the third pulley 96, the medical silica gel suction cup 11 and the first pulley 942 adopted in the first embodiment and the fourth pulley 831 adopted in the second embodiment are all conventional designs, and will not be described in detail in the present invention.

The foregoing shows and describes the general principles and features of the present invention, together with the advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
