Description
Technical field:
The present invention relates to medical instruments field, specifically a kind of infusion device with automatic liquid-stopping structure.
Background technique:
Existing infusion device needs patient or family members to watch close when medical fluid soon drips off, and medical fluid in medicine bottle is prevented to be finished
It changes bottle not in time, admits air into bottom hose under dropping funnel or blood backflow, increase infusion risk.
Currently, also having many structures for stopping liquid for infusion device, one kind as disclosed in Patent No. CN101905052A
Infusion fixator and safe infusion stop liquid device, are located at the plug part below floating part including floating part, one, the floating part
Extend a hollow connector with accommodating space and down, the positioning hole of transfusion fixator is passed through by connector.But
It is complex that liquid device structure should be stopped, higher cost.
For another example a kind of safety drop piston disclosed in Patent No. CN2601096, the integral position of drop plug are placed in bottle
It is that cavity, drop plug float on the top of a dropping liquid at the top of drop plug in liquid, the top of drop plug is " J " word shape of cavity,
So the technical issues of solving drop liquid stream complete obstruction bottleneck, can be easier.The drop plug stops that liquid effect is poor, blocks the effect of bottleneck
Fruit is unobvious, however it remains medical fluid drips off in the bottom hose admitted air under dropping funnel or the medical-risk of blood backflow.
Summary of the invention:
The object of the invention is in order to solve existing issue, and provide a kind of infusion dress with automatic liquid-stopping structure
It sets, medical fluid can be prevented to flow down when medical fluid will be finished, in the bottom hose for preventing air from entering under dropping funnel or blood backflow, guarantee
Infusion safety.
Technology solution of the invention is as follows:
A kind of infusion device with automatic liquid-stopping structure, including Perfusion drip funnel, be arranged in the Perfusion drip funnel from
Dynamic only liquid structure and the top hose, the bottom hose that are connected with the Perfusion drip funnel, the automatic liquid-stopping structure includes buoyancy portion
It is greater than the gravity in the buoyancy portion, the buoyancy portion with the gravity in the only liquid portion being located at below the buoyancy portion, the only liquid portion
Radius be greater than the bottom hose caliber, it is described only liquid portion can extend into the bottom hose.
Above-mentioned technical proposal stops liquid structure, in the more situation of dropping funnel inner liquid medicine amount, only liquid knot by being arranged in dropping funnel
Structure is swum on medical fluid liquid level under the action of buoyancy, and with the reduction of liquid volume, only liquid structure will fall the liquid for blocking dropping funnel
Body outlet, carries out only liquid.The gravity in the only liquid portion is greater than the gravity in the buoyancy portion, guarantees that stopping liquid portion is always positioned at lower section,
Ensure that only liquid portion is matched with bottom hose.
Only liquid portion includes the only liquid zone being connected with the buoyancy portion and stops positioned at described described in as a preferred embodiment of the above solution,
The tube wall of boot section below liquid zone, the only liquid zone and the bottom hose is in sealing contact.
The diameter of the boot section is less than the internal diameter of the bottom hose as a preferred embodiment of the above solution,.
The length of the only liquid zone is at least 0.3cm as a preferred embodiment of the above solution, and only the leakproofness of liquid structure, is improved
Only liquid effect guarantees infusion safety.
The only link position in liquid portion and the buoyancy portion, which is equipped with, as a preferred embodiment of the above solution, surrounds the connection position
The only liquid film for the outer ring setting set, further increases the leakproofness of only liquid structure, improves and stop liquid effect, guarantee infusion safety.
It is provided with extension between the buoyancy portion and the only liquid portion as a preferred embodiment of the above solution, enables to medicine
Liquid there are also it is a small amount of when, just play prevention effect, be further ensured that infusion safety.
The beneficial effects of the present invention are: effectively medical fluid can be prevented to flow down when medical fluid will be finished, and prevent air from entering
In bottom hose under dropping funnel or blood backflow, guarantee infusion safety.

In addition, only the link position in liquid portion 202 and buoyancy portion 201, which is equipped with, surrounds the connection in order to reinforce only liquid effect
The only liquid film of the outer ring setting of position, as only liquid portion 202 is gradually extend into bottom hose 30, due to downward liquid flow, only
Liquid film can be also adhered on the lower surface of dropping funnel under the action of liquid, play the role of sealing to medical fluid, reinforce stopping liquid effect
Fruit.
It should only liquid device (claiming float) immerse 3/4 in liquid, and expose 1/4, because above there is the drop constantly instilled, and essentially
The centre of funnel can generate outside wave, there is a kind of outside wave strength when drop drop is in liquid surface moment, to
In the depth to funnel outer wall of outer, and the wave strength to center can be generated, having arrived all strength in center can offset, so center
Strength it is minimum, therefore float is generally on the instillation face of drop, in addition, float can generate up and down with the instillation of drop
Movement, as jumping, because there is color, it is obvious that.
The above is only intended to understand method and core concept of the invention, it is noted that for the art
, without departing from the principle of the present invention, can be with several improvements and modifications are made to the present invention for those of ordinary skill, this
A little improvement and modification also fall into the protection scope of right of the present invention.
