Description
Technical field
This utility model relates to technical field of medical instruments, more particularly to a kind of disposable transfusion device.
Background technology
The disposable transfusion device being currently widely used in hospital is all to drip speed formula, infusion flow needs to hold by experienced doctor or nurse, judge the size of infusion flow by observing the speed dripping speed during transfusion, infusion flow when but the transfusion device of this fast formula is difficult to intuitively and accurate assurance is infused, the requirement that the very difficult satisfied modern times infuse.
Utility model content
For solving above-mentioned problems of the prior art, this practicality provides a kind of disposable transfusion device that can very intuitively and the most accurately read infusion flow.
The technical solution of the utility model is: a kind of disposable transfusion device, including bottle cap perforator, infusion tube and the flow regulator being located on infusion tube, also include catheter, the upper end of described catheter is connected with described bottle cap perforator, the lower end of described catheter is connected with described infusion tube, the inwall of described catheter stretches out and forms at least one flat-shaped body, described flat-shaped internal being from top to bottom provided with along described catheter inwall and the internal guiding gutter connected of described catheter, the outer surface of described flat-shaped body is provided with graduation mark；Being provided with the circular buoyancy post moved up and down with liquid level in described catheter, the side of described circular buoyancy post is uniformly provided with at least three spiral lamination grooves connected with described guiding gutter, described circular buoyancy post is additionally provided with the circle indicatrix corresponding to described graduation mark.
Described spiral lamination groove extends to bottom from shallow to deep in the middle part of circular buoyancy post.
Described guiding gutter from top to bottom becomes larger in the described flat-shaped internal degree of depth.
The upper end of described catheter is provided with upper limit mouth；The lower end of described catheter is provided with lower limit mouth.
Described graduation mark includes dripping speed/minute track line and ml/hour graduation mark.
The disposable transfusion device that the utility model proposes is by arranging catheter and the flat-shaped body formed that stretched out by the inwall of catheter, the outer surface of flat-shaped body is provided with graduation mark, flat-shaped internal from top to bottom it is provided with along catheter inwall and the internal guiding gutter connected of catheter, circular buoyancy post it is provided with in catheter, the outer surface of circular buoyancy post is provided with the circle indicatrix corresponding to described graduation mark, and the side of circular buoyancy post is uniformly provided with at least three spiral lamination grooves connected with guiding gutter.So very directly perceived and the most accurately can read infusion flow by the graduation mark that the indicatrix on circular buoyancy post is corresponding and set capacity during transfusion.

Detailed description of the invention
As depicted in figs. 1 and 2, the disposable transfusion device that the utility model proposes, including catheter 1, bottle cap perforator 4, infusion tube 5, the flow regulator 6 being located on infusion tube 5, liquid medicine filter 7 and intravenous needle, bottle cap perforator 4 is provided with air inlet 41, the upper end of catheter 1 is connected with bottle cap perforator 4, the lower end of catheter 1 is connected with infusion tube 5, the inwall of catheter 1 stretches out and forms at least one flat-shaped body 2, catheter 1 and flat-shaped body 2 are all transparent, the upper end of catheter 1 is provided with upper limit mouth 11, and the lower end of catheter 1 is provided with lower limit mouth 12.From top to bottom being provided with the guiding gutter 22 that connect internal with catheter 1 along catheter 1 inwall in flat-shaped body 2, the outer surface of flat-shaped body 2 is provided with graduation mark 21.Being provided with the circular buoyancy post 3 moved up and down with liquid level in catheter 1, circular buoyancy post 3 is additionally provided with the circle indicatrix 31 corresponding to graduation mark 21, indicatrix 31 is located at the upper end of circular buoyancy post 3.
The guiding gutter 22 degree of depth in flat-shaped body 2 from top to bottom becomes larger, and the reading of corresponding graduation mark 21 is the biggest, represents that flow is the biggest.
In the present embodiment, the inside and outside extension of the outer wall of catheter 1 forms two symmetrical flat-shaped bodies 2, and graduation mark 21 includes dripping speed/minute track line and ml/hour graduation mark.
As shown in Figure 3, the bottom of circular buoyancy post 3 is tip, the side of circular buoyancy post 3 is uniformly provided with at least three spiral lamination grooves 32 connected with guiding gutter, so makes whole transfusion device air communication, and spiral lamination groove extends to bottom from shallow to deep in the middle part of circular buoyancy post.
Operation principle of the present utility model is:
As shown in Figure 4, when aneroid is closed, circular buoyancy post can get lodged at lower limit mouth.
As shown in Figure 5 and Figure 6, during transfusion, medicinal liquid can pour in catheter from top to bottom, and then medicinal liquid can be flowed in infusion tube through spiral lamination groove from guiding gutter, after being full of medicinal liquid in infusion tube, medicinal liquid contacts with circular buoyancy post, circular buoyancy post will float and moves upward along catheter, until the thrust of medicinal liquid flow velocity be subject to circular buoyancy post buoyant equilibrium time, circular buoyancy post just stops in catheter, and the reading that now indicatrix on circular buoyancy post is corresponding with graduation mark is exactly the most per minute speed and flow per hour.If the flow regulator now tightened up on regulation infusion tube, flow velocity will diminish, and now circular buoyancy post rises, until circular buoyancy post reaches to stop in catheter during balance again, now corresponding graduation mark reading will diminish；If the flow regulator now unclamped on regulation infusion tube, flow velocity will become big, now the flow velocity thrust of the faster medicinal liquid of circular buoyancy major gene will decline, and during until circular buoyancy post reaches to stop in catheter during balance again, corresponding graduation mark reading will become big.
If as it is shown in fig. 7, close flow regulator in infusion process, will be full of medicinal liquid in mozzle, circular buoyancy major gene does not has the promotion of medicinal liquid flow velocity to rise to get lodged at upper limit mouth.
Above specific embodiment is only in order to illustrate design of the present utility model, and those of ordinary skill in the art can make various deformation and change under design of the present utility model, within these deformation and change are included in protection domain of the present utility model.
