Description
Technical field
The utility model belongs to the field of medical instrument technology, in particular to a kind of disposably to stop liquid exhaust gas filter infusion apparatus.
Background technique
Commonly used a kind of medical instrument when infusion apparatus is treatment disease, required when being infused patient using
Infusion apparatus.Currently, the common general infusion set of medical field is by contact pin, air inlet pipe, upper tubing, dropping funnel, lower infusion tube, adjusting
Switch, filter and intravenous needle composition.General infusion set is when infusion has just started, medical fluid enters dropping funnel, since medical fluid is by weight
The double influence of power and pressure, easily forms the gas-liquid mixture of gas and medical fluid, which can enter rapidly simultaneously
In transfusion catheter below dropping funnel, bubble phenomenon when forming infusion.At the same time, since the micro-bubble in lower infusion tube has
Surface tension, these micro-bubbles can be adsorbed on the inner wall of lower infusion tube in infusion process, exclude the bubble ratio therefore generated
It is more difficult.These bubbles have the danger into patient's body in infusion process, cause the danger for leading to patient's aeroembolism because of bubble
Evil.
Therefore, medical staff is before being infused, it is necessary to be infused again after being completely exhausted out the bubble in lower infusion tube.Usually
The manual method for excluding gas is: after bottle plug puncture unit is inserted into transfusion bottle stopper, first squeezing dropping funnel with hand, medical fluid is made to enter dropping funnel
It is interior, while dropping funnel being hung upside down, after being filled with a certain amount of medical fluid in dropping funnel, dropping funnel is disposed vertically rapidly, a large amount of gas can be prevented
The generation of bubble；Another method is first to close adjuster, after being filled with a certain amount of medical fluid in dropping funnel, then slowly opens and adjusts
Device, to reduce the generation of bubble.These manually operated methods are all comparatively laborious, time-consuming, are not easy the air in infusion apparatus
Discharge；And after the operation that medical staff completes the air in exclusion infusion apparatus, often also remains a small amount of air and be infused
In device, due at this time, it may be necessary to medical staff again excludes the air remained in infusion apparatus bit by bit, exhaust
Stability it is also not high, be unfavorable for promptly be infused and rescue critically ill patient.
Now also there is exhaust apparatus or have only liquid device, but this product, during clinical use, function is all relatively single.
Utility model content
Disposably stop liquid exhaust gas filter infusion apparatus the purpose of this utility model is to provide a kind of, which can be automatic
It is exhausted, while having the function of only liquid and filtering, so that medical staff shortens in this way it is not necessary that infusion apparatus is exhausted
Former evacuation time, facilitate medical staff it is easy to operate, save the waiting time, increase working efficiency.
The utility model is to be achieved through the following technical solutions:
A kind of disposably only liquid exhaust gas filter infusion apparatus, including puncture outfit and with the sequentially connected top hose of puncture outfit,

Shell and lower case are fixed, and only the lower part of liquid filter membrane is contacted with supporting table.
The only liquid filter membrane supports to form umbrella-shaped structure by supporting table.
The upper housing and lower case is screwed or is plugged and fixed；Top connection and lower contact are quick connector or Shandong
That connector.
The supporting table is frustum structure, and drainage trough is vertically arranged along the outer wall of supporting table.
It is provided with spiral interface outside lower contact, is equipped with internal screw thread inside spiral interface.
The exhaust hole number is one or more.
The gassing prevention device includes the diversion column being arranged in dropping funnel, and diversion column is provided centrally with to be connected to bottom hose
Through-hole, diversion trench is provided at the top of diversion column, diversion trench is connected to dropping funnel inner cavity and through-hole.
The distance of the water conservancy diversion trench bottom to water conservancy diversion column bottom is dropping funnel length1/3~1/2。
The puncture outfit is two, two puncture outfit bottom connections.
Compared with prior art, the utility model has technical effect beneficial below:
The utility model disposably stops liquid exhaust gas filter infusion apparatus, including critical component gassing prevention device and medical filtration
Device, gassing prevention device eliminate infusion apparatus medical fluid and enter the bubble in front tube, and medical fluid enters the mistake of liquid medicine filter by bottom hose
It in filter chamber body, is dropped on only liquid filter membrane, due to stopping the filtering of liquid filter membrane, liquid can be along the center of only liquid filter membrane to four
Week uniformly flows down and is filtered, and prevents the clogging of dropping liquid process, effectively raises the efficiency of filtering.In addition, root
According to mechanics fluid principles, the gas vent of filter cover can will timely enter the surplus air in filter and be discharged, and eliminate
Bubble in medical fluid, improves the efficiency of exhaust.Finally, due to which drainage trough is arranged in supporting table top, dropping liquid process liquids
Portion of residual is had on the only film surface of liquid filter membrane, the only liquid filter membrane after filtering liquid is due to membrane material tension force effect, two sides
Equilibrium air pressure is formed, when liquid has been transfused fastly, automatic liquid-stopping avoids air from entering human body.Have only to realize infusion apparatus
Liquid, exhaust, the effect for filtering three-in-one.The transfusion system structure is simple, design is reasonable, has retention high-efficient, and cross filtering velocity
Spend big feature.
It further, is beveled structure due to stopping liquid filter membrane when filtering liquid with this millipore filter, when filtering drips
It is beveled structure due to stopping liquid filter membrane, liquid can be uniform around along the center of only liquid filter membrane on only liquid filter membrane
Leave and be filtered, beveled structure increases the contact area of filtering, eliminates eddy effect, prevents the stifled of dropping liquid process
Phenomenon is filled in, the efficiency of filtering is effectively raised.Therefore filtering flow resistance is small, and will not result in blockage situation, on the other hand also reduces
Micropore blocking effect caused by little particle absorption.
Further, supporting table is frustum structure, and drainage trough is vertically arranged along the outer wall of supporting table, guides liquid along frustum knot
Drainage trough on structure, which enters in lower contact, to be discharged, and the clogging in lower contact is eliminated.
Further, gas can be discharged from dropping funnel in time in time for gassing prevention device, effectively prevent starting dropping liquid mistake
Bubble inputs the harm of human body in infusion apparatus when journey.Effectively realize the effect of preliminary exhaust bubble.
