When step motor 3 drives screw slider 5 to one side of standing groove 2 through threaded rod 4 when sliding, locating piece 9 can slide inside the constant head tank of seting up on external splint 8 lateral wall to accessible locating piece 9 is released the inside air of constant head tank, and then when the air passes through tubular whistle 10, the air can blow tubular whistle 10 and sound, and then the sound of accessible tubular whistle 10 reminds patient and attendant, make patient and attendant can be better observe the condition of infusion, in order to guarantee the leakproofness between locating piece 9 and the constant head tank simultaneously, can set up the rubber seal pad on the lateral wall of locating piece 9.
In the sliding process of the inner clamping plate 6, the positioning rod 11 can slide along with the inner clamping plate 6, and meanwhile, the inner clamping plate 6 can be enabled to be inclined in the sliding process due to the limitation of the positioning cavity on the positioning rod 11, so that the sliding of the inner clamping plate 6 is more stable.
After the bottle stopper puncture outfit of the infusion apparatus is placed in the placing groove 2, when the inner clamping plate 6 moves to one side of the placing groove 2, gas in the sliding cavity of the pushing plate 12 can enter the cavity of the inner clamping plate 6 through the gas inlet pipe 14, so that the air in the inner clamping plate 6 can be increased, the rubber soft sheet 13 can be used, the contact area between the inner clamping plate 6 and the infusion apparatus can be made to be larger, the fixing effect of the inner clamping plate 6 on the infusion apparatus can be made to be better, and meanwhile, the rubber sealing ring can be arranged on the periphery of the pushing plate 12 so as to enhance the sealing performance of the rubber soft sheet.
When the push plate 12 slides in the sliding cavity, and the positioning block 9 slides in the positioning groove, the sliding cavity of the push plate 12 and the positioning groove of the outer clamping plate 8 can be replaced with the outside air through the air guide pipe, and meanwhile, the air in the sliding cavity of the push plate 12 can enter the cavity of the inner clamping plate 6 through the air inlet pipe 14 more through the blocking of the blocking ball 15, and meanwhile, the air in the positioning groove of the outer clamping plate 8 can blow the tubular whistle 10 better through the blocking of the blocking ball 15.
When the bottle stopper puncture device punctures the bottle stopper of the infusion bottle, the liquid medicine in the infusion bottle possibly flows out of the infusion bottle, and the liquid medicine can be guided out of the placement groove 2 through the arrangement of the guide groove 17, so that the situation that the liquid medicine possibly pollutes the bottle stopper of the infusion bottle and causes the liquid medicine in the infusion bottle to be denatured is effectively avoided.
When the plugging ball 15 is attached to the side wall of the air duct, the rubber pad 18 can increase the contact area between the plugging ball 15 and the air duct, so that the sealing performance of the plugging ball 15 is stronger.
When the thread slider 5 slides inside the infusion bottle holder 1, the anti-abrasion ball 19 can change the sliding friction between the thread slider 5 and the infusion bottle holder 1 into rolling friction, so that the abrasion between the thread slider 5 and the infusion bottle holder 1 is less.
The front, rear, left, right, up and down are all based on fig. 1 in the drawings of the specification, the face of the device facing the observer is defined as front, the left side of the observer is defined as left, and so on, according to the viewing angle of the person.
