Abstract
The utility model discloses a novel venous transfusion device, which comprises a Murphy's dropper (1) with a tapered outlet and a floating ball (4) arranged in the Murphy's dropper (1). The novel venous transfusion device is characterized by also comprising an alarm device (6); and the lower half part of the surface of the floating ball (4) in the Murphy's dropper (1) is coated with a metal layer (4-1), two electrode plates (5) are embedded in the outlet of the Murphy's dropper (1), the surfaces of the electrode plates (5) are arranged to be flush with the surface of the outlet of the Murphy's dropper (1), and the electrode plates (5) are respectively connected with the anode and the cathode of a power supply of the alarm device (6). When liquid medicine is almost completely injected, the liquid medicine outlet can be sealed automatically, air can be prevented from entering a human body, and alarms can be uttered automatically.
Description
Technical field
This utility model relates to imports the intravital apparatus of human body with medium, a kind of intravenous transfusion device of specific design.
Background technology
Present intravenous transfusion device comprises common Murphy type burette and tube for transfusion, and wherein, Murphy type burette is a transparent body, see through it and can observe the situation of transfusion, as: whether speed whether transfusion is normally carried out, infused and medicinal liquid are totally lost etc.Before its shortcoming was that medicinal liquid is totally lost, necessary careful observation of patient or nurse personnel dripped sky in order to avoid infuse, thereby causes air input thromboembolism or tube for transfusion blood back phenomenon to take place, and causes adverse consequences and brings unnecessary trouble for the medical care people to patient person.In order to overcome this problem, the patent No. is to disclose a kind of " multi-functional Murphy type burette " in 200520115348.6 the utility model patent description, its key that addresses the above problem is to be provided with a ball float in Murphy type burette, and the bottom medicine liquid outlet of Murphy type burette is done coning; When the medicinal liquid in the Murphy type burette soon was totally lost, ball float descended along with medicinal liquid and is plugged on the medicine liquid outlet, thereby avoids the air admission human body.It is simple in structure and convenient in use.But it still needs patient or nurse personnel constantly to observe, and in time notifies the nurse to pull out pin or replacing medicinal liquid when stopping with the box lunch transfusion.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of improved transfusion device, when it soon is totally lost at medicinal liquid, both can block medicine liquid outlet automatically, avoids the air admission human body, but auto-alarm-signal keying device again.
The technical scheme that this utility model solves the problems of the technologies described above is:
A kind of novel intravenous transfusion device, it comprises that outlet is conical Murphy type burette and places its interior ball float, is characterized in that described intravenous transfusion device also comprises a warning devices; The Lower Half on the ball float surface in the described Murphy type burette is coated with metal level, the outlet of described Murphy type burette is embedded with two electrode slices, the surface of this electrode slice is surperficial concordant with the Murphy type burette outlet, and is connected with the both positive and negative polarity of warning devices power supply respectively.
A kind of novel intravenous transfusion device described in the utility model, wherein, the surface of the episphere of described ball float scribbles the color that is easy to watch.When in the Murphy type burette body liquid being arranged, the ball float that has a color float over liquid above, under the effect of dropping liquid, do not stop activity, be convenient to observe fluid infusion velocity and whether unobstructed.
A kind of novel intravenous transfusion device described in the utility model, wherein, described electrode slice is magnetic sheet metal.Adopt the effect of carrying magnetic electrode slice to be, under before ball float drops to the natural enclosing liquid outlet gradually with medicinal liquid, will inhaling in advance, both can improve sealing effectiveness, can improve ball float again and be fixed in stability on the medicine liquid outlet.
A kind of novel intravenous transfusion device described in the utility model, wherein, described warning devices can be an independently phonetic alarm, also be to be a wireless alarm, this wireless alarm is made up of discharger and receiving system, wherein, the power positive cathode of discharger is connected on described two electrode slices, and receiving system is arranged to nurse station or therapeutic room.
In intravenous transfusion device described in the utility model, the Lower Half on ball float surface is coated with metal level, because the density of metal is big than the density at other positions of ball float, so ball float has the hemisphere of metal level to be positioned at the below when floating on the medicinal liquid in the Murphy type burette; When transfusion finished the medicinal liquid face and descends, band metal level hemispherical portion was plugged on the liquid outlet of taper and connects siren.This shows that this intravenous transfusion device can stop transfusion and send alarm signal automatically when transfusion is near completion.
Description of drawings
Fig. 1 and Fig. 2 are the structural representation of a kind of specific embodiment of novel intravenous transfusion device described in the utility model, and wherein Fig. 1 is a front view, and Fig. 2 is the enlarged drawing of the A-A profile of Fig. 1.
The specific embodiment
Referring to Fig. 1 and Fig. 2, intravenous transfusion device of the present utility model comprises a Murphy type burette 1, be connected its up and down two medicinal liquid input pipe 2 and medicinal liquid outlet tube 3 and be located at ball float 4 in it, wherein, it is conical that the outlet of Murphy type burette 1 is, be embedded magnetic electrode slice 5 in this outlet, the surface of this electrode slice 5 and the flush of outlet, the sealing effectiveness when dropping down onto this outlet with assurance ball float 4; The lower end of these two electrode slices 5 extends in the following body 1-1 of outlet, and in the both sides of this body 1-1 a kerf is set respectively, so that two electrode slices 5 are exposed, is convenient to be connected with the power lead of warning devices 6.Described ball float 4 is made by the plastics that density is lower than medicinal liquid, and its size is complementary with medicine liquid outlet, and the Lower Half on these ball float 4 surfaces is coated with layer of metal layer 4-1, and the first half is coated with chromatic colour, watches being convenient to.Described warning devices 6 is a wireless alarm, is made up of discharger and receiving system, and wherein, the both positive and negative polarity of the power supply of discharger is connected on above-mentioned two electrode slices, and receiving system is positioned in the nurse station.When medicinal liquid is about to be totally lost, ball float 4 descends with the medicinal liquid liquid level and drops down onto in the outlet of Murphy type burette, with this outlet shutoff and connect the power supply of discharger, discharger sends the signal that finishes of infusing, receive this signal and send voice suggestion by the receiving system in the nurse station, inform the bed label that the nurse infuses and finishes.
