When the air bubble in the communicating tube between the fixed tube 103 and the electronic infusion pump 101 flows through the fixed tube 103, the air bubble enters from the left side of the fixed tube 103, when the air bubble flows through the middle part of the fixed tube 103, the air bubble moves upwards along the inside of the fixed cylinder 301, the air bubble flows through the through hole of the rotating member 402 in the upwards moving process, flows into the fixed cylinder 301 through the through hole of the rotating member 402, and exchanges with the liquid medicine in the upper half part of the fixed cylinder 301 under the action of the upward rising of the air bubble, so that the upper half part of the fixed cylinder 301 is converted into the air bubble by the liquid medicine.
When the bubbles in the fixed cylinder 301 need to be cleaned, the electronic infusion pump 101 is used for controlling the second driving part 404 to rotate the rotating part 402, the rotating part 402 rotates 90 degrees, the flow blocking part 401 shields the through hole in the middle of the rotating part 402, the liquid medicine in the fixed cylinder 301 is separated from the liquid medicine in the fixed pipe 103, and the liquid medicine in the fixed cylinder 301 becomes an independent space.
The electronic infusion pump 101 controls the first driving part 304 to regularly pull or push the upper part of the electronic infusion pump upwards or downwards, so that bubbles in the fixed barrel 301 are regularly cleaned, when the first driving part 304 pushes the upper part of the electronic infusion pump downwards, the fixed plate 302, the second elastic part 305, the sliding plate 3051, the sliding frame 306 and the infusion tube 309 move downwards, and in the downward movement process of the sliding plate 3051, the bubbles in the fixed barrel 301 upwards surge from an air outlet in the middle of the sliding plate 3051, so that the bubbles enter between the sliding plate 3051 and the fixed plate 302.
When the lower side of the sliding frame 306 contacts with the liquid surface in the fixed cylinder 301, the sliding frame 306 floats on the liquid surface in the fixed cylinder 301 under the action of the floating force of the sliding frame 306, the fixed plate 302 and the upper parts thereof continuously move downwards, the sliding frame 306 and the blocking piece 307 gradually move upwards and block the air outlet in the middle of the sliding plate 3051, the liquid medicine below the sliding frame 306 is prevented from flowing into the upper part of the sliding plate 3051, and the liquid medicine in the fixed cylinder 301 is blocked from bubbles through the sealing fit of the blocking piece 307 and the sliding plate 3051, so that the liquid medicine in the fixed cylinder 301 is always kept below.
The U-shaped frame 308 is separated from the baffle 3011 in the downward moving process of the fixed plate 302, the U-shaped frame 308 moves upwards under the action of the adjacent springs, the U-shaped frame 308 is not contacted with the two one-way valves 3021, the second elastic piece 305 is extruded in the continuous downward moving process of the fixed plate 302, the second elastic piece 305 is in a compressed state, bubbles between the fixed plate 302 and the sliding plate 3051 are jacked in the downward moving process of the fixed plate 302, the two one-way valves 3021 on the fixed plate 302 are opened under the action of pressure, and the bubbles between the fixed plate 302 and the sliding plate 3051 are discharged outwards from the air outlet of the fixed plate 302, so that the bubbles in the fixed cylinder 301 are removed.
In the process of removing the bubbles in the fixed cylinder 301, the bubbles generated in the fixed tube 103 flow from the left part of the fixed tube 103 to the middle part of the fixed tube 103, and the bubbles generated in the fixed tube 103 are gathered on the lower side surface of the baffle 401 under the action that the height of the lower side surface of the baffle 401 is higher than the height of the liquid medicine in the fixed tube 103, so that the bubbles in the fixed tube 103 cannot flow into the connecting tube 105 in the process of removing the bubbles in the fixed cylinder 301.
When the bubbles between the fixed plate 302 and the sliding plate 3051 are removed completely, the two one-way valves 3021 are reset and closed, so that the fixed plate 302 is kept sealed, at this time, the liquid medicine is injected into the catheter 310 at regular time by the electronic infusion pump 101, in the process of injecting the liquid medicine into the catheter 310 by the electronic infusion pump 101, the first driving member 304 has pulled the lower part upward, the liquid medicine in the catheter 310 flows into the infusion tube 309, the liquid medicine in the infusion tube 309 before the liquid medicine is injected between the fixed plate 302 and the sliding plate 3051 into the infusion tube 309, under the action of the liquid guiding member 3093, the flow rate of the liquid medicine around the liquid guiding member 3093 is increased, and by the impact of the liquid medicine on the second sliding member 3092, the sliding housing 3091 and the U-shaped frame 308, the adjacent springs are compressed in the process of moving the U-shaped frame 308, and the one-way valve 3021 is pressed by the U-shaped frame 308, so that the one-way valve 3021 is not opened in the process of injecting the liquid medicine.
The chemical solution in the liquid transfer tube 309 flows between the fixed plate 302 and the sliding plate 3051, and the liquid transfer tube 309 supplements the chemical solution to the fixed plate 302 and the sliding plate 3051.
The sliding frame 306 gradually breaks away from contact with the liquid surface of the residual liquid medicine in the fixed cylinder 301 in the upward moving process, so that the blocking piece 307 breaks away from blocking the air outlet of the sliding plate 3051, and then the liquid medicine between the fixed plate 302 and the sliding plate 3051 flows into the lower part of the sliding plate 3051 to be fused with the residual liquid medicine in the fixed cylinder 301, and after the bubbles in the fixed cylinder 301 are discharged again, the capacity of the liquid medicine in the fixed cylinder 301 is kept unchanged.
When the U-shaped frame 308 moves into contact with the baffle 3011, the fixed plate 302 and its upper parts have moved to a base position, at which time the fixed cylinder 301 is filled with liquid medicine, the electronic infusion pump 101 has stopped replenishing liquid into the fixed cylinder 301, and the U-shaped frame 308 has pressed the two check valves 3021, causing the two check valves 3021 to remain closed.
