Description of drawings
Fig. 1 is the structural representation one of this utility model;
Fig. 2 is the structural representation two of this utility model;
Among the figure be: bottle plug puncture unit 1, air inlet pipe filter 2, outstanding gallbladder drift along that relief valve drips kettle 3, flow rate of liquid actuator 4, liquid medicine filter 5, intravenous needle 6, helmet 7, drips that the kettle liquid level is regulated air bag a, dripped kettle b, inclined-plane feed tube c, the stifled d of outstanding gallbladder suspension relief valve, squash type valve opening machine e, drip pot lid f, outstanding gallbladder water blocking 1., hollow adjusting plug counterweight chamber 2., the buoyancy air chamber 3..
The specific embodiment
Below in conjunction with accompanying drawing, this utility model is further described:
Like Fig. 1, shown in 2; Have the outstanding gallbladder relief valve that drifts along and drip the infusion set of kettle; Be with helmet 7 on the intravenous needle 6 that comprises bottle plug puncture unit 1 and flow rate of liquid actuator 4, is connected through the liquid pipe with flow rate of liquid actuator 4, the intravenous needle 6, it is characterized in that: the air inlet of the air inlet pipe 2 that is connected with liquid bottles through bottle plug puncture unit 1 is provided with air inlet pipe filter 2; Liquid pipe between bottle plug puncture unit 1 and the flow rate of liquid control valve 4 is provided with the outstanding gallbladder relief valve that drifts along and drips kettle 3; Liquid pipe between flow rate of liquid control valve 4 and the intravenous needle 6 is provided with liquid medicine filter 5.
The described outstanding gallbladder relief valve that drifts along drips kettle 3 and comprises and being connected with bottle plug puncture unit 1 usefulness flexible pipe and the inclined-plane feed tube c of hollow; Inclined-plane feed tube c penetrates and is positioned at the top that kettle b is deeply dripped in pot lid f central authorities of dripping of dripping kettle b top; Adopt the design of the feed tube on inclined-plane to avoid the stifled d of outstanding gallbladder suspension relief valve to suspend too high and entering that blocked liquid like this; With on the bottom liquid pipe that drips kettle b squash type valve opening machine e is installed, when relief valve d can not float voluntarily, available finger pushed squash type actuator e repeatedly, liquid in pipe can easily make progress to have dashed to open and hang gallbladder suspension relief valve and block up d, makes the transfusion device operate as normal.
Described cylinder infundibulate or the prism infundibulate that kettle b is the hard transparent material made.
Be connected with on described pot lid f and drip the liquid-feeding tube that kettle b inside communicates; Liquid-feeding tube is connected with and drips kettle liquid level adjusting air bag a; Such design had both made things convenient for and had added medicinal liquid at any time, had solved a kettle b again and itself can not be extruded, and regulated the problem of dripping liquid level in the kettle again; Dripping kettle b set inside has outstanding gallbladder suspension relief valve to block up d.
As shown in Figure 1, the buoyancy air chamber that the stifled d of described outstanding gallbladder suspension relief valve comprises top 3., 2. 3. the floating power air chamber be connected with hollow adjusting plug counterweight chamber; 1. 2. hollow adjusting plug counterweight chamber be connected with the outstanding gallbladder water blocking of bottom, and be provided with close gas in hollow adjusting plug counterweight chamber in 2. and move regulating piston; Will hang the stifled d of gallbladder suspension relief valve put into drip kettle b before; The close gas 2. interior through hollow adjusting plug counterweight chamber moves moving up and down of regulating piston; Regulate the 1. pressure of middle liquid of 3. interior buoyancy of buoyancy air chamber and outstanding gallbladder water blocking; And then reach when the stifled d of outstanding gallbladder suspension relief valve has liquid in dripping kettle and remain perpendicular to liquid level, when liquid is about to carry when finishing, the stifled d of outstanding gallbladder suspension relief valve sinks to and drips kettle b bottom; Liquid outlet is shut the most at last then, thereby has prevented backflow of blood and air admission and the danger that produces.
As shown in Figure 2; The buoyancy air chamber that the stifled d of described outstanding gallbladder suspension relief valve comprises top 3.; Floating power air chamber bottom 3. is an enclosed construction; Be positioned at hollow adjusting plug counterweight chamber simultaneously 2., and be full of hollow adjusting plug counterweight chamber 2., 1. 2. hollow adjusting plug counterweight chamber be connected with the outstanding gallbladder water blocking of bottom.Regulate gas-liquid proportion during use, through power buoyancy air chamber bottom 3. in hollow adjusting plug counterweight chamber moving up and down in 2., regulate outstanding gallbladder water blocking volume size 1., and then obtain the big or small adjusting of proportion of gas-liquid.
1. described outstanding gallbladder water blocking adopts the TR thin rubber film production to form, and sterile liquid is housed at outstanding gallbladder water blocking in 1..
Below in conjunction with accompanying drawing, manipulate explanation to this utility model is affected: the medical worker is in inspection transfusion effect duration and do not have under other abnormal conditions, and elder generation's closing liquid flow regulator 4 during use inserts infusion bottle with bottle plug puncture unit 1 then and hangs up properly; Then push repeatedly with hands and drip kettle liquid level adjusting air bag a, an adjusting kettle liquid level reaches about 2/3 in the kettle to be located, and makes tube for transfusion become " u " shape, and the flow rate of liquid actuator 4 that comes up drains air, closing liquid flow regulator 4; Pull out helmet 7, intravenous needle 6 is thrust the vein of the poison that disappeared, after fixing, untie tourniquet, the adjustment flow velocity, transfusion device begins operate as normal.
When one bottle of liquid was about to be totally lost, the outstanding gallbladder relief valve d that drifts along sank to shutting the liquid outlet that drips at the bottom of the kettle, from this moment; Transfusion stops automatically and blood back air inlet problem can not take place; If when needing to continue transfusion, as long as bottle plug puncture unit 1 is pulled up, the subsequent use infusion bottle that inserts the poison that disappeared immediately hangs up properly; The reuse hands pushes repeatedly and drips kettle liquid level adjusting air bag a, makes the interior liquid level of a kettle b reach about 2/3 in the kettle and locates.At this moment, relief valve d can not float voluntarily if outstanding gallbladder drifts along, as long as drip the squash type valve opening machine e or the infusion tube at place, kettle below with pointing extruding repeatedly, can easily upwards open and hang the floating relief valve d of gallbladder, and transfusion device begins operate as normal again.
This utility model is simple in structure, has fully solved when unmanned or the carelessness of infusing to forget that liquid is totally lost, and has caused the problem of blood back and air inlet, and then reduced the generation that endangers medical tangles such as patient's life and health safety.
Above embodiment only is used to explain the preferred implementation of this utility model; But this utility model is not limited to above-mentioned embodiment; In the ken that said field those of ordinary skill is possessed; Any modification of being done within spirit of this utility model and the principle, be equal to and substitute and improvement etc., it all should be encompassed within the technical scheme scope that this utility model asks for protection.
