Specific embodiment
Automatic cut-off acoustic conductance dropping funnel, connect and form disposable automatic cut-off acoustic conductance intravenous transfusion device with outside upper tubing and outer subordinate's tube for transfusion, the design discharge of disposable automatic cut-off acoustic conductance intravenous transfusion device is much larger than the actual flow of venous transfusion, therefore in infusion process, all the time have pressure in disposable automatic cut-off acoustic conductance intravenous transfusion device, come round in acoustic conductance tympanum 1-2-4 reason acoustic conductance mouth 1-2-3 and the outside of automatic cut-off acoustic conductance dropping funnel, therefore the pressure in acoustic conductance tympanum 1-2-4 is normal pressure, be less than tympanum 1-2-5, the medicinal liquid pressure that lower tympanum 1-2-7 is outer, in transfusion, lower tympanum will upwards have been opened, leave following go out fluid catheter 1-3-2 go out fluid catheter inlet 1-3-3, after medicinal liquid is totally lost the decline of medicinal liquid face, overpressure will disappear naturally, and the lower tympanum of heaving will restore to the original state, and again covers out the fluid catheter inlet, cut-off state occurs.
Disposable automatic cut-off acoustic conductance intravenous transfusion device is in infusion process, identical with common disposable intravenous infusion set operation sequence, the hand-held new disposable intravenous transfusion device of medical personnel, first automatic cut-off acoustic conductance dropping funnel is inverted, to wear bottle is needled in medicinal liquid bottle again, medicinal liquid will flow in automatic cut-off acoustic conductance dropping funnel by upper tubing, while in the medicinal liquid face, rising to the given medicinal liquid face graduation mark of automatic cut-off acoustic conductance dropping funnel, slowly automatic cut-off acoustic conductance dropping funnel is turned again, come round in acoustic conductance tympanum 1-2-4 reason acoustic conductance mouth 1-2-3 and the outside of automatic cut-off acoustic conductance dropping funnel, therefore the pressure in acoustic conductance tympanum 1-2-4 is normal pressure, be less than tympanum 1-2-5, the medicinal liquid pressure that lower tympanum 1-2-7 is outer, at this moment the interior lower tympanum 1-2-7 of automatic cut-off acoustic conductance dropping funnel 1 will upwards expand and heave under pressure, what break away from its below goes out fluid catheter inlet 1-3-3 or spool inlet opening 2-3-4-2, form the water conservancy diversion cavity, medicinal liquid can flow out from going out fluid catheter, flow in outer subordinate's tube for transfusion.
Be positioned at dropping funnel inside because of acoustic conductance tympanum 1-2-4 in infusion process, medicinal liquid drips and can directly drop on tympanum 1-2-5, perhaps drop on the medicinal liquid face directly contacted with upper tympanum, drop sound is received in to the greatest extent in acoustic conductance tympanum 1-2-4, and provides acoustic conductance mouth 1-2-3 to conduct to outside corollary system to provide information for the venous transfusion monitoring administration.
Disposable automatic cut-off acoustic conductance dropping funnel intravenous transfusion device, after medicinal liquid approaches the automatic cut-off of being totally lost, liquid level no longer descends, the transfusion halted state appears, the medicinal liquid of now staying in automatic cut-off dropping funnel and lower tube for transfusion still maintains certain pressure, has avoided air to enter in lower tube for transfusion and anti-generation of flowing back to the blood phenomenon.
If continue transfusion, the continuous bottle of rear operator that change dressings only need gently pinch the dropping funnel epimere of automatic cut-off acoustic conductance dropping funnel, and closed downcomer inlet 1-3-3 or spool liquid outlet 2-3-4-3 will open, and medicinal liquid starts to flow, and enters the continuation transfusion state.
In process of production, the structural member in this utility model adopts conventional production technology to produce, and manufacturability is strong, and production cost is low; Adopt the manufacture of multimode injection moulding, on production efficiency under tympanum 1-2-4 tympanum 1-2-7 can adopt latex or silicone rubber elastomeric material to make, guarantee and elastic effect.
Automatic cut-off acoustic conductance dropping funnel provided by the utility model, its modern design, be skillfully constructed, and takes full advantage of the characteristic of liquid and pressure, gravity, negative pressure acoustic conductance principle, reached the automatic cut-off of venous transfusion, sound conduction, the purpose of blood return prevention; Its automatic cut-off acoustic conductance structure is spacing at liquid outlet one end in dropping funnel inside, do not affect formation and the observing effect of drop in dropping funnel, similar to the traditional appearance of common disposable intravenous infusion set dropping funnel, sound conduction structure does not affect the flow effect of automatic cut-off effect and medicinal liquid.
Be equipped with disposable intravenous infusion set of the present utility model, do not change medical personnel's work habit, its operation sequence is identical with disposable intravenous infusion set, is easy to learn and use; Compared to other stopper, have simple in structure, good sealing effect, the characteristics such as manufacturability is strong; Can effectively reduce medical personnel's labor intensity in clinical practice, save a large amount of human resources who takies for observing the transfusion progress, make more standard of infusion management, nurse more intimate.
