Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of transfusion device.
Background technology
Transfusion device is the conventional intravenous injection device of hospital, and our common transfusion device mainly comprises puncture needle, Murphy's burette, speed-regulating switch, syringe needle and connects their tube for transfusion at present.Generally, this common tube for transfusion can meet the needs of patient infusion completely.But for some special patients, the amount to transfusion liquid and transfusion speed have strict requirement, nursing staff can only judge amount of infusion and transfusion speed by range estimation and personal experience in the past, can not meet like this disease human needs.
Summary of the invention
The purpose of this utility model is by the improvement to traditional infusion device, makes nursing staff can have control more accurately to amount of infusion and transfusion speed.
For achieving the above object, this utility model adopts following technical scheme: a kind of quantitatively/control fast transfusion device, comprise successively from top to bottom puncture needle, upper tubing, Murphy's burette, lower tube for transfusion and syringe needle, on described lower tube for transfusion, be provided with speed-regulating switch, on described upper tubing, be from up to down disposed with gauge tap, volumetric bottle and lower gauge tap, a side of the hollow shell of described speed-regulating switch is provided with graduation mark, on the friction pulley of speed-regulating switch, be decorated with the straight line through the center of circle, described graduation mark with friction pulley is positioned through fitting a straight line of the center of circle.
On upper tubing, have additional upper and lower gauge tap and volumetric bottle, can first by opening upper gauge tap, the liquid in transfusion bag be put into volumetric bottle quantitatively like this, then open lower gauge tap, carry out normal infusion operation, this structure can have more accurately and grasp the amount of transfusion liquid.On traditional by-pass cock, improve simultaneously, be provided with passing through fitting a straight line of the center of circle and can realize the location to friction pulley on graduation mark and friction pulley in the side of hollow shell, thereby can control more accurately the speed of transfusion.
Volumetric bottle top is provided with the steam vent with cap, can guarantee that liquid enters volumetric bottle smoothly.For the ease of processing, volumetric bottle adopts regular cylindrical plastic bottle.According to dripping the residing position of friction pulley under speed fixing, determine the straight line that passes through the center of circle on the graduation mark box friction pulley of hollow shell side, preferably drip speed and be chosen in 10 droplets/point, 30 droplets/point, 50 droplets/point.
The beneficial effects of the utility model: can overcome in common transfusion process and be difficult to defect quantitative and that speed can not accurately be controlled, guarantee the effect of infusion treatment, this utility model is simple in structure, easy to make.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model specific embodiment;
Fig. 2 is the structural representation of speed-regulating switch in Fig. 1;
Wherein, 1, upper puncture needle, 2, Murphy's burette, 3, lower tube for transfusion, 4, syringe needle, 5, upper tubing, 6, speed-regulating switch, 7, upper gauge tap, 8, volumetric bottle, 9, lower gauge tap, 61, hollow shell, 62, friction pulley, 81, exhaustor.
The specific embodiment
Also further illustrate by reference to the accompanying drawings below by embodiment:
As shown in Figure 1, the utility model discloses a kind of quantitatively/control fast transfusion device, its structure is followed successively by by order from top to down: the tube for transfusion of upper puncture needle 1, upper gauge tap 7, volumetric bottle 8, lower gauge tap 9, Murphy's burette 2, speed-regulating switch 6, syringe needle 4 and connection said structure, tube for transfusion is divided into upper tubing 5 and lower tube for transfusion 3 take Murphy's burette 2 as boundary.Wherein, the switch that upper and lower gauge tap 7 is " opening " and " pass " two states, can control liquid and enter volumetric bottle 8 and complete quantitatively.Described volumetric bottle 8 is cylindrical plastic structure, and its surface is marked with the scale of express liquid volume, is also provided with the exhaustor 81 with cap at its top.Speed-regulating switch 6 is added with the positioner of friction pulley 61 on common speed-regulating switch, described positioner is the graduation mark being engraved in respectively on hollow shell 61 and friction pulley 62, both are used in conjunction with the location that can complete friction pulley, drip speed thereby can control exactly.
In the time of patient infusion, open gauge tap 7 keep simultaneously lower gauge tap 9 close and volumetric bottle 8 on exhaustor 81 open, liquid enter volumetric bottle 8 complete to transfusion liquid quantitatively.Gauge tap 7 is closed in pass, open lower gauge tap 9 simultaneously, after regulating, start transfusion, at this moment need to regulate speed-regulating switch 6 to carry out regulating transfusion speed as required, in the time that the graduation mark on friction pulley 61 aligns with the graduation mark on hollow shell 61, represent that friction pulley 62 located, transfusion speed is fixed, this utility model is provided with the anchor point of three friction pulleys, corresponding 50 droplets/point respectively, 30 droplets/point, 10 droplets/point drip speed.
Claims (4)
- One kind quantitatively/control fast transfusion device, comprise successively from top to bottom puncture needle (1), upper tubing (5), Murphy's burette (2), lower tube for transfusion (3) and syringe needle (4), on described lower tube for transfusion (3), be provided with speed-regulating switch (6), it is characterized in that: on described upper tubing (5), be from up to down disposed with gauge tap (7), volumetric bottle (8) and lower gauge tap (9), a side of the hollow shell (61) of described speed-regulating switch (6) is provided with graduation mark, on the friction pulley (62) of speed-regulating switch (6), be decorated with the straight line through the center of circle, graduation mark on described speed-regulating switch (6) with friction pulley (62) is positioned through fitting a straight line of the center of circle.
