Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a kind of embodiment of the utility model, rather than whole realities
Apply example.Based on the embodiment in the utility model, those of ordinary skill in the art institute under the premise of creative work is not made
The every other embodiment for obtaining, belongs to protection domain of the present utility model.
As depicted in figs. 1 and 2, the anti-blood back self-closed type transfusion device includes Mo Feishi droppers 1 and is arranged on Mo Feishi drops
Self-styled closure in pipe 1；In specific implementation, the material of self-styled closure can be consistent with the material of Mo Feishi droppers 1, is disposed as
Medical polymer material；When liquid level declines in Mo Feishi droppers 1, liquid is gone out by self-styled closure blocking Mo Feishi droppers 1
Mouthful, prevent air from into woven hose 5, it is to avoid blood back phenomenon.
Self-styled closure includes that barrel shape drips cup 2 and is connected to the distal guide wire 4 of barrel shape drop cup 2 lower end, in specific implementation, far
End seal wire 4 is located in woven hose 5, and dripping cup 2 to barrel shape by distal guide wire 4 positions；Barrel shape drop cup 2 outer wall shape with not
The inner wall shape of Fei Shi droppers 1 is identical, and the outer bottom 7 of barrel shape drop cup 2 fits with the inner bottom surface 8 of Mo Feishi droppers 1, Neng Gouchong
Air point is effectively prevented from into woven hose 5.
The volume of the barrel shape drop inner chamber body 3 of cup 2 of the anti-blood back self-closed type transfusion device is 2 ~ 4ml, and barrel shape drips the density of cup 2
It is 0.75*103 kg/m3~0.85*103kg/m3；Wherein, the height of barrel shape drop cup 2 is the 1/3 ~ 1/2 of the height of Mo Feishi droppers 1,
The density of the density less than water of barrel shape drop cup 2, when filling a certain amount of liquid in the Mo Feishi droppers 1, barrel shape drop cup 2 just can be
In the presence of buoyancy, in suspended state.
The outer wall shape of barrel shape drop cup 2 is identical with the inner wall shape of Mo Feishi droppers 1, barrel shape the drop outer wall of cup 2 and Mo Feishi
Spacing d between the inwall of dropper 1 is 2 ~ 2.5mm, and in specific implementation, when normal infusion, liquid first instills cavity 3, treats chamber
It is upper with gap water level during just overflow to barrel shape drips the gap between the outer wall of cup 2 and the inwall of Mo Feishi droppers 1 after body 3 is full
Rise, when the gravity that barrel shape drips cup 2 drips the buoyancy suffered by cup 2 with the gravity sum of the water of filling in cavity 3 less than barrel shape, bucket
The outer bottom 7 of type drop cup 2 is just separated with the inner bottom surface 8 of Mo Feishi droppers 1, and now, liquid flow to human vein from woven hose 5.
As shown in figure 1, when transfusion liquid is less, when liquid level begins to decline in Mo Feishi droppers 1, barrel shape drips cup 2 with liquid
The liquid level of body declines together, when liquid level would fall to Mo Feishi 1 bottoms of dropper, the outer bottom 7 and Mo Feishi drops of barrel shape drop cup 2
The inner bottom surface 8 of pipe 1 is brought into close contact, under the gravity of the water filled in the gravity and cavity 3 of barrel shape drop cup 2, by Mo Feishi droppers 1
Liquid outlet block, and barrel shape drop cup 2 bottom material be hydrophilic material so that barrel shape drip cup 2 outer bottom 7 and Mo Feishi
The laminating of the inner bottom surface 8 of dropper 1 is even closer, forms good sealing effectiveness.
Because liquid level is no longer reduced, pressure necessary to having maintained and stabilized transfusion thoroughly solves asking for transfusion blood back
Topic, reduces the Psychological phobia of patient；And prevent air from into woven hose 5, medical personnel no longer need exhaust, reduce work
Measure.
The bottom of the barrel shape drop cup 2 of the anti-blood back self-closed type transfusion device is provided with a colored portion 6, in specific implementation, can
Red as resolution color；The 2/3 of the pipe interior diameter of a diameter of woven hose 5 of distal guide wire 4, both ensure that and had dripped cup 2 to barrel shape
Ground effectively positioning, in turn ensures that the usual of liquid stream；In specific implementation, guidewire length can be set in Mo Feishi droppers 1 manage
The difference of height and the barrel shape drop cup height of cup 2 adds 10mm again.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or new using this practicality
Type.Various modifications to these embodiments will make it will be apparent that defined herein for those skilled in the art
General Principle can in other embodiments be realized in the case of the spirit or scope for not departing from utility model.Therefore, originally
Utility model will not be limited and the embodiments shown herein, and be to fit to and principles disclosed herein and novelty
The property consistent scope most wide of feature.
