The utility model has the advantages that: the transfusion that this utility model provided is equipped with the air filtration film with being provided with steam vent and silica gel flexure strip in the automatic exhaust valve device in the steam vent.
1, the steam vent that the air filtration film is housed can make bubble or the complete emptying of air in the medicinal liquid, and the silica gel flexure strip can be realized the unidirectional fluid stopping of medicinal liquid; Thereby reduce the generation of aeroembolism, thrombosis, reduce medical treatment harm and malpractice.
2, this utility model can directly use or be installed in the optional position of transfusion apparatus (like transfusion device, remaining needle, intravenous needle, central venous catheter, prolongation pipe, blood exchange transfusion set etc.); Also can be with the parts of its apparatus that is designed to infuse, like the three-way piece of remaining needle, the liquid medicine filter parts of transfusion device; Use and convenient, can alleviate nurse's workload, quick administration when being particularly suitable for rescue patient, reduce the deflated time when promptly infusing.
Description of drawings
Below in conjunction with accompanying drawing and embodiment this utility model is further described:
Fig. 1 is the front view of this utility model embodiment one;
Fig. 2 is the left view of this utility model embodiment one;
Fig. 3 is the front view of this utility model embodiment two;
Wherein: 1-valve body, 11-inlet, 2-loam cake, 21-steam vent, 3-lower cover, 31-liquid outlet, 4-medicine liquid channel, 5-air filtration film, 6-silica gel flexure strip, 7-liquid medicine filtering membrane.
The specific embodiment
Embodiment one:
Fig. 1 and Fig. 2 have shown the specific embodiment of this utility model transfusion with automatic exhaust valve device; This device can be used for infusion medical apparatus and instruments such as transfusion device, remaining needle, intravenous needle, central venous catheter, prolongation pipe, also can it directly be processed infusion medical apparatus and instruments such as the transfusion device that has this device, remaining needle, intravenous needle, central venous catheter, prolongation pipe.
It comprises valve body 1, loam cake 2 and lower cover 3, and wherein loam cake 2 is installed on the valve body 1 with lower cover 3.
Said valve body 1 is provided with inlet 11, and lower cover 3 is provided with liquid outlet 31, and assembling is formed with medicine liquid channel 4 at valve body 1, loam cake 2 and 3 of lower covers after accomplishing, and this medicine liquid channel 4 is connected said inlet 11 with liquid outlet 31.
For the device that makes present embodiment has the automatic vent function; This example is shaped on two and is used for the bubble of medicine liquid channel or the steam vent 21 (steam vent 21 is connected with medicine liquid channel 4) of air eliminating on said loam cake 2, and in these two steam vents 21, air filtration film 5 is installed.Need to prove: the steam vent 21 on the said loam cake 2 also can be arranged to one, three, four or more, but produces and practice thrift cost for ease, and one or two generally only is set.
For the device that makes present embodiment has unidirectional fluid stopping function, this example is equipped with the silica gel flexure strip 6 that is arranged in the said medicine liquid channel 4 on said lower cover 3.Be specially: said medicine liquid channel 4 has a flexure strip chamber 41 (the flexure strip chamber is the part of medicine liquid channel), and said silica gel flexure strip 6 is arranged in this flexure strip chamber 41.
In addition, this example also is equipped with the liquid medicine filtering membrane 7 (this liquid medicine filtering membrane can adopt common filter membrane, also can adopt the secondary filter film) that is arranged in the said medicine liquid channel 4 on said valve body 1, to come the impurity in the filtering liquid medicine through this liquid medicine filtering membrane 7.
The assembling process of present embodiment is: earlier liquid medicine filtering membrane 7 is contained on the valve body 1, air filtration film 5 is contained on the loam cake 2, and silica gel flexure strip 6 is contained on the lower cover 3; Be installed in loam cake 2 and lower cover 3 on the valve body 1 then and get final product.
The operation principle of present embodiment is: the medicinal liquid at first inlet from the valve body 1 11 gets into medicine liquid channels 4, and the air when medicinal liquid arrives steam vent 21 places in the medicinal liquid excludes through air filtration film 5; After the medicinal liquid of the air of draining passed through liquid medicine filtering membrane 7, the impurity in it was filtered; The medicinal liquid that filters out impurity gets into the flexure strip cavity and contacts with silica gel flexure strip 6, and micro-deformation takes place silica gel flexure strip 6 under the contention effect of medicinal liquid gravity, and the liquid outlet 31 that medicinal liquid overflows through lower cover 3 through distortion place of silica gel flexure strip 6 flows out.In a single day the silica gel flexure strip 6 of distortion loses the contention effect of medicinal liquid gravity; Distortion can be restored immediately; Thereby with medicine liquid channel 4 sealing fluid stoppings (is under the silica gel flexure strip normality medicine liquid channel to be sealed fluid stopping; Under the contention effect of medicinal liquid gravity, produce distortion during work, medicinal liquid overflows through distortion place of silica gel flexure strip).
