The specific embodiment
As shown in Figure 1, Figure 2 and Figure 3, the transfusion bag alarm for infusion with isolator mainly comprises reminiscences 1 and isolator 2; Reminiscences 1 hangs on transfusion bag 3 and uses, and reminiscences mainly comprises snap ring 11, fuselage 12; Fuselage 12 is provided with air inlet and spigot joint 13, is provided with air flue in fuselage, and an end of air flue communicates with spigot joint 13, and the other end is provided with pressure transducer; Also be provided with alarm device and control device in fuselage; Pressure transducer is connected to control device by holding wire.
As shown in Figure 4, Figure 5 and Figure 6, isolator 2 comprise signal pipe 21, lower spigot joint 22 and be positioned at the middle part air bag 23; Air bag is upper signal pipe and lower spigot jointly separate fully, upper signal pipe 21 and spigot joint 13 sockets, and an end socket of lower spigot joint and air inlet pipe 4, the other end of air inlet pipe communicates with the top of a capsule 5.
Air bag can be under the effect of negative pressure spigot joint direction compression downwards; The distortion of air bag causes the space enlargement in the signal pipe cavity, thereby produces negative pressure, and negative pressure signal transmits air intake duct by spigot joint 13, thereby passes to pressure transducer.
The hollow utricule that described air bag is an end opening, opening and lower spigot joint communicating, blind end is towards upper signal pipe, medicinal liquid in transfusion bag has flowed, and drips medicinal liquid in capsule when dirty, and the air that can make to drip in capsule produces negative pressure, air bag is subject to the impact of negative pressure, spigot joint Direction distortion, reduce the negative pressure of dripping in capsule downwards, makes medicinal liquid can continue lower.
The wall of described air bag is provided with a plurality of parallel fold, can flexural deformation, and when air bag is out of shape to opening, these fold can overlap.
Medicinal liquid in transfusion bag down flows into and drips kettle 5 by upper dropper 6, because transfusion bag can be shunk, medicinal liquid flows away, make the air pressure in bag be less than the external world, external atmosphere pressure just can be flattened transfusion bag accordingly, inside and outside air pressure is consistent, also make medicinal liquid can continue drop rhythmically and enter a kettle 5, flow to human body by the lower dropper 7 communicated with a kettle again, in infusion process before medicinal liquid in transfusion bag has flowed, drip the liquid that remains certain capacity in kettle, usually occupy and drip 1/2 to 2/3 of kettle capacity.Drip the medicinal liquid that keeps certain capacity in kettle, not only can prevent that the dropper dropping liquid from causing dripping the air intravasation in kettle not in time, after can also the medicinal liquid in transfusion bag flow, continue to have medicinal liquid to input blood vessel, to the nursing staff, set apart and replace transfusion bag.
The medicinal liquid dripped in kettle 5 flows to lower dropper 7, the pressure balance of dripping in kettle is broken, the air of medicinal liquid top thins out, form negative pressure, at this moment, because air inlet pipe 4 communicates with dripping kettle and air bag, the air in air inlet pipe 4 and air bag also thins out, form negative pressure, air bag is spigot joint direction compression downwards under the effect of negative pressure; The distortion of air bag causes the space enlargement in the signal pipe cavity, thereby produces negative pressure, and negative pressure signal transmits air intake duct by spigot joint 13, thereby passes to pressure transducer, and pressure transducer output pressure signal is to control device.Formed negative pressure owing to dripping in kettle, will inhale medicinal liquid in transfusion bag and enter to drip in kettle and supplemented, thereby make the pressure dripped in kettle reach balance, corresponding, the pressure of air inlet pipe and air bag Air also is balanced, the pressure signal disappearance.When control device is received the pressure signal that pressure transducer is passed back, control device is analyzed judgement to signal, when pressure signal lower than predefined parameter value, although or pressure signal reaches predefined parameter value, but at N below second, control device can not opened alarm device and report to the police the lasting time.
Medicinal liquid in transfusion bag has flowed, the medicinal liquid dripped in kettle also can continue to carry toward human body under the effect of gravity, drips the kettle herb liquid and reduces, and from the medicinal liquid of transfusion bag, does not splash into supplementary again, the pressure balance of dripping in kettle will be broken, the air of medicinal liquid top thins out, and forms negative pressure, corresponding, air in air inlet pipe and air bag also thins out, form negative pressure, pressure transducer detects the variation of pressure, and by pressure signal transmission to control device.Along with the medicinal liquid dripped in kettle reduces, the signal that pressure transducer passes to control device is more and more stronger.
The pressure signal detected from pressure transducer when control device continues N more than second, and/or pressure signal meets or exceeds predefined parameter value, control device will be opened alarm device and report to the police, and reminds sufferer and nurse's transfusion to complete, and must process in time.
Control device can also combine with the nurse call system of hospital, when control system is opened alarm device warning reminding sufferer, can also pass through the original nurse call system of hospital, directly alarm signal is issued to the nurse.
When negative pressure reaches certain degree, just can inhale the capsule spigot joint Direction distortion downwards of taking offence, thereby the air space of medicinal liquid top is reduced, air pressure is increased, but air pressure still is less than the pressure from blood vessel, thereby the speed of medicinal liquid input is slowed down, when the medicinal liquid in dripping capsule and lower dropper further reduces, air bag continues spigot joint Direction distortion downwards, all the time form certain pressure above medicinal liquid, make medicinal liquid can input lentamente human body on the one hand, can also prevent because of the too small blood backflow caused of air pressure above medicinal liquid simultaneously in lower dropper.
As shown in Figure 3, reminiscences 1 hangs over transfusion bag 3 belows and uses, the annular that snap ring 11 is a side opening, and snap ring is stuck on the bottleneck of Soft Roll; Lower limb at snap ring is provided with the contiguous block 14 to downward-extension, and the lower limb of contiguous block is connected with the roof of fuselage 12, makes fuselage hang over the snap ring below.
When snap ring is stuck on bottleneck, fuselage is positioned at the bottle neck below.
As shown in Figure 4, can also fuselage towards on dropper groove 15 is set on the end face of dropper 6, the dropper groove is semicircle, its diameter is greater than the diameter of dropper; During use, upper dropper is positioned at the dropper groove, contributes to stablize upper dropper and drips a kettle, and in minimizing, dropper and a kettle rocks.
Employing, with the transfusion bag alarm for infusion of isolator, needn't arrange the special messenger to check the transfusion progress again, has alleviated sufferer and family members' pressure, and sufferer can feel at ease to have a rest, and busy also can the settling down to of family members processed.The work that makes the nurse is effective percentage more also, has reduced the time of checking in advance the waste of transfusion progress, and also corresponding the minimizing changed the liquid waste caused in advance, can also effectively prevent blood backflow.
Because infusion apparatus is all disposable, but reminiscences is need to be reusable, in order to prevent the cross infection that may cause that is connected between infusion apparatus and reminiscences, therefore, disposable isolator is set between reminiscences and infusion apparatus, just can effectively prevents the cross infection that may cause that is connected between infusion apparatus and reminiscences.
