The specific embodiment
As shown in Figure 1:
Bottle plug puncture unit 1 inserts infusion bottle, and bottle plug puncture unit 1 connects a fast actuator 2, drips a fast actuator 2 and connects fluid paths 3, below the only liquid film 4-1 of the delivery outlet of fluid path 3 in protection chamber 4, above baffle plate 4-2; Protection is fixedly connected with baffle plate 4-2 in chamber 4, baffle plate 4-2 is provided with liquid-leaking nozzle 4-2-1, floating block 4-3 floats in the liquid in protection chamber 4 while in protection chamber 4, medicinal liquid being arranged, protection chamber 4 interior during without medicinal liquid floating block 4-3 fall after rise and stop up outlet 4-4, in the middle of floating block 4-3, upper and lower all has outstanding tip or a pyramidal structure, the tip of top is for the liquid-leaking nozzle 4-2-1 on baffle plate 4-2, the tip of below is for outlet 4-4, the lowermost end in protection chamber 4 is provided with infusion pipeline 5, outlet 4-4 is communicated with infusion pipeline 5, only above liquid film 4-1, air space 8 is being arranged; 5 structure from the infusion bottle to the infusion pipeline so at least should have two in the present invention, and they be independently, separated; In this example, concrete and vivid in order to illustrate, be designed with three infusion bottles, respectively 3. number infusion bottle, 2. number infusion bottle, 1. number infusion bottle from left to right, wherein 1. number infusion bottle is the infusion bottle of first transfusion, its gas passage 6 directly connects air inlet 7,3. number infusion bottle, 2. gas passage 6 delivery outlets of number infusion bottle be inserted in protection chamber 4 and the air space 8 in liquid film 4-1 top only in; Protection chamber 4 has three, and also, each correspondence an infusion bottle for floating block 4-2, outlet 4-4, air space 8; Protection chamber 4 integral body are sealed.
Application process explanation of the present invention:
Three bottle plug puncture units 1 are inserted respectively to three infusion bottles i.e. 3. number infusion bottle, 2. number infusion bottle, 1. number infusion bottle, regulate respectively the fast actuator 2 of dripping of three infusion bottle belows and control a speed, discharge bubble in tube for transfusion, now the liquid in three infusion bottles all can the fluid path 3 in bottle plug puncture unit 1 utilizes gravity to take advantage of a situation to flow in each self-corresponding protection chamber 4; Now, liquid is full of in protection chamber 4, make floating block 4-3 be subject to buoyancy and float up to baffle plate 4-2 position, in the liquid-leaking nozzle 4-2-1 of the pyramidal structure of floating block 4-3 upper end from baffle plate 4-2, emerge, baffle plate 4-2 is fixing floating block 4-3 position, stops it to continue floating, because the pyramidal structure of floating block 4-3 lower end has been left outlet 4-4, outlet 4-4 is communicated with infusion pipeline 5, makes whole transfusion unimpeded; But now, owing to only having the gas passage 6 that 1. number infusion bottle is corresponding to be connected with ambient atmosphere by air inlet 7,1. the medicinal liquid in number infusion bottle starts transfusion; Due to the only effect of liquid film, medicinal liquid can not enter air space 8, and air space 8 still maintains the cavity state, and while only having air space 8 directly to communicate with external atmosphere pressure, next bottle just can start transfusion; Taken space because the protection chamber 4 corresponding with 1. number infusion bottle is interior by medicinal liquid; and 2. the gas passage 6 of number infusion bottle passes in the air space 8 in the protection chamber 4 of 1. number infusion bottle; 2. the gas passage 6 of number infusion bottle can not join with outside atmosphere by the gas outlet 7 that 1. the corresponding protection chamber 4 of number infusion bottle communicates; so 2. number infusion bottle does not start transfusion; in like manner, 3. number infusion bottle does not start transfusion yet.
As shown in Figure 2:
When 1. number infusion bottle medicinal liquid infusion-completed, its corresponding protection chamber 4 internal liquids reduce, and floating block 4-3 is subject to buoyancy and reduces on the one hand, falls the outlet 4-4 that stops up liquid in 4 cavitys of protection chamber after rise, prevents that air from entering tube for transfusion; 2. the interior air space 8 in the gas passage 6 of number infusion bottle to the protection chamber 4 that 1. number infusion bottle is corresponding being connected with ambient atmosphere by the protection chamber 4 that 1. number infusion bottle is vacated on the other hand, 2. number infusion bottle starts transfusion thus.In like manner, 2., after number infusion bottle infusion-completed, the floating block 4-3 in its corresponding protection chamber 4 stops up the outlet 4-4 of the interior liquid of cavity in protection chamber 4, and 3. number infusion bottle is connected with ambient atmosphere, and 3. number infusion bottle starts transfusion.
As shown in Figure 3:
When 3. number infusion bottle, 2. number infusion bottle, after 1. three infusion bottle inner liquid medicines of number infusion bottle all are totally lost; three the corresponding protection of infusion bottle chamber 4 interior floating block 4-3 all fall after rise; be inserted in the interior liquid outlet 4-4 of corresponding protection chamber 4 cavitys, stop up liquid-transport pipe-line 5, prevent that air from entering.
As shown in Figure 4:
Circular port in the middle of baffle plate 4-2 is upper can be fixed on relevant position by floating block 4-3, in the surrounding of circular port, is provided with liquid-leaking nozzle 4-2-1, and the top medicinal liquid can flow down by liquid-leaking nozzle 4-2-1.
As shown in Figure 5:
The structure of floating block 4-3 is a cylinder, and cylinder is upper and lower respectively a pyramidal structure.Cylinder and upper taper structural material density are less, and the pyramidal structure density of bottom is larger.While in protection chamber 4, being full of medicinal liquid, floating block 4-3 floating, the circular hole in the middle of the pyramidal structure at top and baffle plate 4-2 are upper agrees with, and the circular hole in the middle of baffle plate 4-2, emerges, control floating block 4-3 floating position, the medicinal liquid of baffle plate 4-2 top can flow to below by liquid-leaking nozzle 4-2-1; When protection chamber 4 is cavity, floating block 4-3 bottom pyramidal structure is agreed with mutually with cavity body structure, and with the form fit that exports 4-4, floating block 4-3 falls after rise and blocks outlet 4-4, has also just blocked liquid-transport pipe-line 5.
