The utlity model has following advantage:
This utility model transfusion device, by the reservoir with anti-air embolism is set between cork perforator and Murphy's burette, when air enters reservoir through cork perforator, thromboembolism can move down along with liquid level, until the outlet at bottom of just in time blocking reservoir, and while moving down along with liquid level, form negative pressure in the Murphy's burette, add the original venous pressure of human vein, liquid level is also no longer moved down, can prevent effectively that air from moving down.
Description of drawings
Fig. 1 is the structural representation of this utility model transfusion device;
Fig. 2 is the cutaway view of baffle plate 2 among Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, this utility model transfusion device, comprise cork perforator 1, pass through Murphy's burette 8 and syringe and the flow regulator on conduit 9 between Murphy's burette 8 and the syringe 10 that conduit is communicated with cork perforator 1 successively, be provided with the reservoir 3 that is used for anti-air embolism between cork perforator 1 and the Murphy's burette 8, reservoir 3 inside are separated into upper plenum 4 and following cavity 5 by the baffle plate with holes 2 of horizontally set; Be provided with the conical thromboembolism 6 that matches with following cavity 5 bottoms in the following cavity 5, the bottom of thromboembolism 6 is provided with a lead-in wire 7, the process auxiliary balance thromboembolism 6 that is used for water conservancy diversion and is infusing.
The density of thromboembolism 6 is less than the density for the treatment of loading liquid, with the outlet that prevents that thromboembolism 6 stops up reservoir 3 bottoms in the infusion process; In order to reach better sealing effectiveness, the density on thromboembolism 6 tops is more preferably greater than the density of thromboembolism 6 bottoms, and the average density of thromboembolism 6 is less than the density for the treatment of loading liquid; Density as thromboembolism top can be greater than the density for the treatment of loading liquid, and the density of thromboembolism 6 bottoms can be less than the density for the treatment of loading liquid, and the average density of thromboembolism 6 is less than the density for the treatment of loading liquid; Thromboembolism 6 can be suspended in when transfusion treat in the loading liquid that when medicinal liquid was totally lost, buoyancy disappeared, and because the density on thromboembolism 6 tops is bigger, can produce better sealing.The material of thromboembolism 6 is preferably selected the material of stable in properties for use, reacts with medicinal liquid avoiding.Concrete thromboembolism 6 can adopt two kinds of different materials of density to make, and the material of density greater than medicinal liquid density to be measured adopted on thromboembolism 6 tops, and the material of density less than medicinal liquid density to be measured adopted in thromboembolism 6 bottoms, and the average density of thromboembolism 6 is got final product less than the density for the treatment of loading liquid; Perhaps, adding one thromboembolism 6 the higher authorities that adopt density less than the material preparation of the density for the treatment of loading liquid adopts density greater than the material for the treatment of loading liquid density.
