Description
Technical field
The present invention relates to a kind of intravenous transfusion device is related to, specifically a kind of automatic liquid-stopping intravenous transfusion device.
Background technology
Traditional intravenous transfusion device it is general by intravenous infusion needle, infusion tube, liquid medicine filter, flow regulator, drop kettle,
Bottle plug puncture unit, air inlet pipe air cleaner composition, when transfusion is completed or transfusion group replaces, if processing is not in time, decoction
Flow to end and be easily caused blood backflow even air input body effect patient body health；The shield of medical worker has also been aggravated simultaneously
Working strength is managed, easily triggers doctor-patient dispute.With the increasingly raising continued to develop with clinical requirement of infusion techn, people
A safer more effectively good product is expected to have, automatic liquid-stopping transfusion apparatus is exactly a kind of a kind of new of replacement traditional infusion device
Intravenous transfusion device, is characterized in when liquid has been transfused soon, can automatic liquid-stopping, avoid air from entering vein automatically.It is existing from
Dynamic only liquid transfusion device mainly has two kinds of designs, and the first design is that float is set in drop kettle, float lower end shape correspondence drop kettle
Liquid outlet shape, declines float with liquid level and declines, and when decoction drips space-time, float is placed exactly in drop kettle lower end, cuts off going out for drop kettle
Liquid path, effectively prevents air from entering in patient body.But this design has the following disadvantages：One is when float is placed exactly in drop
Cut-out drop kettle in kettle lower end goes out liquid path, now automatic liquid-stopping, and in transfusion device tens of milliliters of decoction is blocked in below float
It can not continue to input human body, cause the waste of decoction.Two be to block drop kettle liquid outlet with float lower end, it is necessary to makes float lower end
With drop kettle liquid outlet Dock With Precision Position, extruding of the intravenous transfusion device in the links such as transport easily makes drop kettle, float deformation, caused close
Seal reliability not high, safety is low.Second of design is, in the effect using filter membrane surface tension force, to make atmospheric pressure and filter membrane table
When face tension force, hydrostatic pressing, human vein pressure reach balance, decoction is rested in transfusion device, so as to reach the function of automatic liquid-stopping.
It is this design exist deficiency be：Patient is difficult to discover and understands this design, causes the anxiety that patient is unnecessary.
The content of the invention
To solve the above problems, the invention provides a kind of automatic liquid-stopping intravenous transfusion device.
The technical solution adopted in the present invention is：The automatic liquid-stopping intravenous transfusion device includes bottle plug puncture unit 1, infuses soft
Pipe 2, drop kettle 3, flow regulator 4, intravenous infusion needle 5, drop kettle 3 are made up of upper drop kettle 6 and lower drop kettle 7, and lower drop kettle 7 is socketed in
Drip the lower end of kettle 6；The cavity of upper drop kettle 6 is vertebral body shape；The upper end of upper drop kettle 6 is provided with inlet 8, the upper drop cavity of kettle 6 and is provided with
Floating body 10, floating body 10 is spherical structure；The spherical structure of opening upwards, spherical structure are provided between upper drop kettle 6 and lower drop kettle 7
Diameter be equal to cavity lower end narrow opening length, be provided with liquid outlet 9 in the bottom of spherical structure；The lower end of lower drop kettle 7 is provided with
Total liquid outlet 11, side upper end is provided with air filter tube 12, and the outer end of air filter tube 12 is provided with switch 13.
The diameter of the floating body 10 is not more than the diameter of spherical structure.
The diameter of the floating body 10 is equal to the diameter of spherical structure.
The concave surface of the spherical structure scribbles the small material of coefficient of friction.
The outer surface of floating body 10 scribbles the small material of coefficient of friction.
The small material of the coefficient of friction is polytetrafluoroethylene (PTFE).
Compared with existing intravenous transfusion device, the beneficial effects of the invention are as follows：The cavity of upper drop kettle 6 is set to vertebral body
Shape so that the floating body 10 for being not more than spherical structure diameter can be with free movement in the cavity of upper drop kettle 6；The diameter of floating body 10 is little
In the diameter of spherical structure, the preferably diameter of floating body 10 is equal to the diameter of spherical structure, even if drop kettle 3 is slightly tilted, floating body
10 remain to completely cover liquid outlet 9, it is ensured that liquid is static, substantially increases the reliability of only liquid；Spherical structure and floating body 10
Surface scribbles the small polytetrafluoroethylmaterial material of coefficient of friction, can reduce friction system of the floating body 10 in spherical structure surface scrolls
Number；The lower end of liquid outlet 9 opens up air filter tube and switch, after decoction automatic liquid-stopping, lower drop kettle 7 is manually made by compressing switch and big
Gas UNICOM, the decoction now rested in transfusion device can continue to input human body, and effective guarantee therapeutic effect is more beneficial for enhancing
Sufferer promotes the harmony of nurse-patient relationship to the trust of nurse.The design has also taken into full account to be connected with traditional intravenous transfusion device
And cooperation, you can accessory is individually produced, also production can be installed additional with traditional intravenous transfusion device, the production to traditional intravenous transfusion device is set
Standby and process reform is little, the quick transformation of convenient tradition intravenous transfusion device manufacturing enterprise and upgrading.
