It is more safe and efficient during row pushes away medicine repeatedly.
It is provided with medical fluid dropping funnel 7 and medical fluid flow regulator 8 in perfusion tube main body 1, passes through setting for medical fluid flow regulator 8
It sets, can be used to adjust the speed that control medical fluid flows in perfusion tube main body 1, at the center of 7 upper and lower ends of medical fluid dropping funnel
It is respectively arranged with communicating pipe 701 and lower communicating tube 702, the upper end of the upper communicating pipe 701 and the lower end of lower communicating tube 702 are equal
It is connect with perfusion tube main body 1, and was provided with Three-way medicine feeding dropper 9 within upper communicating pipe 701, the setting of Three-way medicine feeding dropper 9, side
Just other drugs are added in the medical fluid into perfusion tube main body 1,7 inside center of medical fluid dropping funnel is vertically arranged with cylindrical type
Floating ball pipe 10 is limited, the lower end of the limit floating ball pipe 10 is open, and is all provided on limit 10 upper surface of floating ball pipe and side wall
Several liquid through-holes 11 are equipped with, the setting of liquid through-hole 11 realizes medical fluid in medical fluid dropping funnel 7 and limits medical fluid in floating ball pipe 10
Between connection limit floating ball pipe 10 to realize medical fluid to the suspension effect of floating plug ball 12 and be internally provided with floating plug ball 12, limit
The setting of position floating ball pipe 10, limits position of the floating plug ball 12 in medical fluid dropping funnel 7, so that floating plug ball 12 is in medical fluid dropping funnel 7
Under the action of medical fluid, it can only be moved on the vertical center position of medical fluid dropping funnel 7, avoid medicine of the floating plug ball 12 in medical fluid funnel 7
Liquid surface suspends movement everywhere, and when moving to 702 top of lower communicating tube, floating plug ball 12 not lower communicating tube 702 just on
Side, therefore cannot rapidly realize the blocking effect to 702 top of lower communicating tube, the air that will cause sub-fraction enters lower company
The inside of siphunculus 702, then as perfusion tube main body 1 enter inside of human body a possibility that, the setting of floating plug ball 12 can avoid
After medical fluid water clock in medicine bottle is complete, fails to find in time, air is caused to enter inside of human body, cause the danger of air embolism.
The working principle of floating plug ball 12 is as follows:
Floating plug ball 12 swims in the surface of medical fluid in medical fluid dropping funnel 7, lands with the decline of medical fluid in medical fluid dropping funnel 7,
Until the pressure inside 1 lower half portion of perfusion tube main body can be smaller and smaller, certain during medical fluid reaches lower communicating tube 702
Under suction function, floating plug ball 12 can be inhaled on the top of lower communicating tube 702,702 top of lower communicating tube be sealed, to avoid sky
Gas enters, and ensure that the infusion safety of the infusion apparatus.
The lower section of the medical fluid flow regulator 8 is provided with the liquid medicine filter 13 of circular configuration, the liquid medicine filter
13 are internally provided with the double-deck polyethersulfone filter film 14, and the perfusion tube main body 1 passes through the top of the double-deck polyethersulfone filter film 14,
And the inside of the double-deck polyethersulfone filter film 14 is extended to, the setting of liquid medicine filter 13 plays the medical fluid inside perfusion tube main body 1
The effect for having arrived filtering, avoids the foreign matter adulterated in drug as medical fluid enters inside of human body, causes additional injury to human body,
Poly (ether sulfone) film has good hydrophily and flux, good chemical stability and inertia, and alkaline PH stablizes, and double-layer structure is set
It sets, have that pollutant carrying capacity is strong, filter opening is regular, uniform, filtering precision is high, will not generate foreign matter and fall off, is small to drug adsorption,
The good feature of drug compatibility, the medical fluid come by the conveying of perfusion tube main body 1 pass through the filtering of the double-deck polyethersulfone filter film 14 work
It is delivered in human vein blood vessel with rear, then by perfusion tube main body 1.
Setting is respectively provided with there are two circular exhausting-gas hole 15 in two circular exhausting-gas holes 15 on the liquid medicine filter 13
There is PTFE polyester to block water film 16, circular exhausting-gas hole 15 is arranged, it can be achieved that excluding to the bubble contained in medical fluid, so that medicine
The flowing of liquid is more smooth, is blocked water film 16 using PTFE polyester, bacterium and particle in environment are effectively prevented while blocking water
Into into the liquid.
Medical fluid surge flask 17, and the medical fluid surge flask are provided between the medical fluid dropping funnel 7 and medical fluid flow regulator 8
Connection between connection relationship between 17 internal structure and each structure and the internal structure and each structure of medical fluid dropping funnel 7
Relationship is identical, and the setting of medical fluid surge flask 17 further improves the security performance of the infusion apparatus, so that medical fluid in medicine bottle
Water clock is complete, when failing to be found in time, can be avoided air and enter in human body, by being total to 7 internal structure of medical fluid dropping funnel
Same-action enhances the reliability of the infusion apparatus.
The diameter of the floating plug ball 12 is less than the diameter of limit floating ball pipe 10, but is greater than the diameter of lower communicating tube 702, guarantees
Floating plug ball 12 under the suspension effect of medical fluid, can move up and down along limit floating ball pipe 10, and when moving to lower communicating tube
When on 702, the top of lower communicating tube 702 can be blocked, the sealing effect to lower communicating tube 702 is realized, to avoid air
Into.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new
