A kind of pressurization intravenous transfusion device

Technical field

This utility model relates to a kind of medical apparatus and instruments, specifically, relates to a kind of pressurization intravenous transfusion device.

Background technology

Present employed intravenous transfusion device is by the medicinal liquid bottle, Murphy's burette, the transfusion sebific duct, dripping fast controller and syringe needle constitutes, when transfusion, the medicinal liquid bottle is positioned over eminence, infusion pressure when forming transfusion, the size of infusion pressure is normally controlled by the height of medicinal liquid bottle, the speed of transfusion is controlled by dripping fast controller, when needs are infused fast, sometimes a fast controller being reached maximum still can not meet the demands, can only increase the speed of transfusion this moment by the height of heightening the medicinal liquid bottle, regulate the height of medicinal liquid bottle, operate cumbersome, and the adjusting of medicinal liquid bottle will be subjected to the restriction of various conditions highly usually, present employed transfusion device scarcely has the alarm device of infusing when finishing, when transfusion, usually all need special personnel and nurse, prevent that medicinal liquid gas after transfusion finishes from entering vein generation malpractice, increased nursing staff's labor intensity.

The utility model content

Problem to be solved in the utility model is at above problem, and a kind of speed that can regulate transfusion by pressue device is provided, and transfusion finishes and can produce warning, easy to operate pressurization intravenous transfusion device.

For addressing the above problem, the technical scheme that this utility model adopted is: a kind of pressurization intravenous transfusion device, comprise medicinal liquid bottle, Murphy's burette, transfusion sebific duct, drip fast controller and syringe needle, transfusion sebific duct between described medicinal liquid bottle and the Murphy's burette is provided with the electromagnetism pressue device, and described Murphy's burette is provided with alarm device.

As a kind of prioritization scheme, described electromagnetism pressue device comprises rubber tube, check valve and electric magnet, and the mobile armature of described electric magnet is connected with pressing plate, and described rubber tube passes between mobile armature and pressing plate, and described check valve is arranged at the two ends of rubber tube.

As a kind of prioritization scheme, described alarm device comprises floating circle, Metal Ball, first make contact, second contact point and the warning circuit that is electrically connected with first make contact, second contact point, described floating circle is arranged in the Murphy's burette, described Metal Ball is connected in the bottom of floating circle, and the described first make contact and second contact point are arranged at the exit of Murphy's burette bottom.

A kind of concrete prioritization scheme, described warning circuit comprises first lead and second lead, described first lead, one end is connected with first make contact, and described second lead, one end is connected with second contact point, is in series with power supply and loudspeaker between the other end of the other end of described first lead and second lead.

This utility model is taked above technical scheme, have the following advantages: because transfusion device is provided with the electromagnetism pressue device, so, transfusion speed is not subjected to medicinal liquid bottle height and drips the restriction of fast controller, can pressurize automatically by pressue device as required, regulate the speed of transfusion, the frequency of moulding pressure and pressurization can be regulated automatically, easy to operate, again because Murphy's burette is provided with alarm device, when transfusion floating circle and Metal Ball swim in the medicinal liquid in the Murphy's burette, after transfusion finishes, under the action of gravity of Metal Ball, floating circle and Metal Ball move downward, and when Metal Ball is run into the first make contact and second contact point, warning circuit are connected, loudspeaker send the sound and produce warning, have improved the safety of transfusion.

The utility model is described in further detail below in conjunction with drawings and Examples.
