Description
Technical field
The present invention relates to medical field, the disc type regulation and control drop of more particularly to a kind of multifunctional adaptive continuous transfusion system
Pipe.
Technical background
Infusion apparatus is the common medical instrument injected for clinical vein, as shown in Figure 1, infusion apparatus is generally by bottle stopper puncture
Device protective case, bottle plug puncture unit, air filter, tongs, Murphy type burette, infusion long duct, flow regulator, liquid
Filter, exit conical connector composition.Infusion apparatus upper end is connected with infusion bottle, and lower end is matched with intravenous infusion needle,
Entire infusion process is completed under gravity.During actual clinical venous transfusion, there is usually one infusions for infusion apparatus
Channel, but generally require to carry out more bottles of infusion bottle continuous transfusions, since the cure mechanism of drug is different, the infusion of more bottles of infusion bottles
Sequence considered critical and must cannot be changed, and otherwise be likely to occur the feelings for interfering with each other and then reducing transfusion effect between drug
Condition.More bottles of infusion bottle continuous transfusions of Present clinical need to complete in the case where the operation of medical staff is intervened, and there are many to lack
Point and inconvenience, it is specific as follows：
First, medical staff needs manually to be vented infusion apparatus before infusion.The mode of exhaust is by luxuriant Fei Shi drops
Manage it is horizontal, when having enough liquid in dropper, with finger squeeze dropper, liquid is made to quickly enter infusion long duct, is passed through
Intravenous infusion needle discharges air, this is a very time-consuming process.In this process, once extruding action is careless slightly,
It will result in the infusion long duct inner wall on the downside of infusion apparatus Murphy type burette and have a large amount of minute bubbles, to discharge these bubbles,
Medical staff needs to flick the tube wall of infusion apparatus with finger, bothers very much and effect is not satisfactory.In addition, by squeezing woven hose
Wall way of discharge air outside the infusion apparatus may also can cause to damage to transfusion catheter, and the transfusion catheter of damage can influence defeated
The infusion performance of liquid device, so as to reduce the reliability of infusion apparatus；
Second, during more bottles of infusion bottle continuous transfusions, need the artificial replacement for constantly carrying out infusion bottle.It is replacing
During infusion bottle, if the liquid level of remaining liquid is less than the lower part of Murphy type burette in infusion apparatus, need to be vented again or again
It is injected intravenously：When liquid level is only lower than dropper a bit of, woven hose is usually wrapped in finger by medical staff from bottom to top
On, air is gradually squeezed out；When liquid level is one big section lower than dropper, medical staff then needs to open cone joint, from infusion
Air is discharged in long duct end, this process will necessarily cause the waste of liquid, while be easy to cause interface infection.Due to doctor
Shield personnel generally require to nurse the patient in multiple wards simultaneously, frequently repeat replacement infusion bottle and take a large amount of time and essence
Power, on the one hand be easy to cause that medical staff's body ＆ mind is tired out, is on the other hand likely to occur difference in cumbersome replacement process
Wrong (for example, not replaced according to correct infusion sequence), causes transfusion effect to have a greatly reduced quality or even cause medical thing
Therefore；
Third, Present clinical venous transfusion, it is impossible to be automatically stopped infusion.At the end of infusion, if medical staff sees
Not in time, liquid level decline is too low for shield, will result in blood back phenomenon, and severe patient causes gas to enter human body, and it is bad to cause aeroembolism etc.
Consequence.Liquid level is too low in order to prevent, and medical staff, patient and family members need to be nursed in real time, and it is unnecessary to cause three
Nervous and psychological burden；
4th, for blood transfusion or valuable liquid, medical staff is needed manually to carry out defeated preceding confirmation and defeated rear cleaning.
Before blood transfusion or valuable liquid, it is necessary to after first confirming that vein conveying is correct with physiological saline, formal conveying could be carried out；Defeated
At the end of liquid, often retentate portion liquid in woven hose needs to be rinsed with physiological saline and is just avoided that liquid waste.It is defeated
Preceding confirmation and defeated rear cleaning are required for professional that could complete, inconvenient.
5th, Present clinical venous transfusion, it is impossible to adjust automatically transfusion speed.Transfusion speed be according to age of patient,
What the combined factors such as the state of an illness and the property of drug determined, transfusion speed setting it is improper it is possible that cause chronic heart failure or other
Serious consequence.Present infusion speed is only with the flow velocity of artificial observation Murphy type burette inner liquid medicine, and adjust flow-rate adjustment dress manually
It puts to complete.On the one hand, flow velocity only is set by objective condition such as the profiles of medical staff with observation Murphy type burette
Limitation, it is impossible to ensure entirely accurate；On the other hand, it is adjusted on this condition in addition to medical staff has permission, patient and family
Belonging to entourage can equally adjust, and this unprofessional adjustment has the risk for upsetting normal infusion process.Have according to investigations
The 38.88% too fast situation of infusion is that patient voluntarily tunes up.
For more bottles of continuous transfusion situations, patent name is " differential to exempt to nurse automatic decanting infusion apparatus and monitor system "
(application number：CN103705998A it) is announced, major defect is：
First, it can only realize the continuous transfusion in the case of more bottles of continuous transfusions, reduce medical staff and replace infusion
The workload of bottle is not directed to the problem of being vented automatically, being automatically stopped infusion and prevent residual liquid in pipe；
Second, using the different modes for generating pressure differential of infusion bottle suspension height, on the one hand infusion space will be proposed
Very big requirement, on the other hand in more bottles of continuous transfusions, due to the limited height that patient to medical staff normally hangs, so will
Can be that nursing staff's suspension infusion bottle causes difficulty；
Third makes multiple floating valves generate pressure differential in a manner that floating valve suspension height is different, equally to infusion
Space and nursing staff hang infusion bottle and cause difficulty；
4th, in a manner that floating valve generates pressure differential as the unidirectionally controlled or different woven hoses of control, due to its knot
Structure is complicated, is influenced by infusion apparatus arrangement and infusion bottle arrangement, there are problems that reliability, reliability is for infusion apparatus
Be very important, if infusion bottle continuous transfusion does not timely enter infusion apparatus, make it is intermediate there are one section of air, will cause compared with
Big accident.
