Beneficial effect
The invention provides a kind of disposable intravenous infusion set automatic cut-off dropping funnel, it utilizes gravity and law of buoyancy, in the time that infusion unit titrimeter inner liquid medicine is soon totally lost, can prevent medicinal liquid face excessive descent and cause counter flow back to blood phenomenon occur; Compared to other stopper, have simple in structure, good sealing effect, the feature such as manufacturability is strong; In clinical practice, can effectively reduce medical personnel's labor intensity, save a large amount of human resources who takies for observing transfusion progress, make more standard of infusion management, nurse more intimate.
Specific embodiment
In venous transfusion, the tube for transfusion inner liquid medicine flow of disposable intravenous infusion set, because being subject to the Flow-rate adjustment restriction of tiny piercing needle and flow control valve, in most transfusions, can not flow by the maximum stream flow of design, making has pressure to exist in the inherent whole infusion process of tube for transfusion; Liquid soup in infusion unit titrimeter, in having pressure, also has buoyancy; Material lower than medicinal liquid density will produce buoyancy in its medicinal liquid, towards medicinal liquid face floating, and simultaneously also can be along with medicinal liquid face declines and declines; If floating agents design is become to specific shape, can seal identical with dropping funnel liquid outlet, in the time that medicinal liquid face declines, it will be along with medicinal liquid face declines, sealing infusion unit titrimeter liquid outlet, stops medicinal liquid face to continue to decline, and realizes cutoff function, make the positive/negative pressure that in stop surface tube for transfusion once, maintenance varies in size from top to bottom, thereby avoid anti-generation of flowing back to blood phenomenon.
The dropping funnel of cut-off certainly 1 in this case, be linked and packed with upper tubing 2 and lower tube for transfusion 4, form disposable from cut-off intravenous transfusion device, in infusion process, identical with common disposable intravenous infusion set operation sequence, the hand-held disposable automatic cut-off intravenous transfusion device of medical personnel, first automatic cut-off dropping funnel 1 is inverted, to wear bottle is needled in medicinal liquid bottle again, medicinal liquid will flow in automatic cut-off dropping funnel 1 in upper tubing 2, while rising to the middle medicinal liquid face graduation mark of automatic cut-off dropping funnel 1 in medicinal liquid face, slowly automatic cut-off dropping funnel 1 is turned again, at this moment the sealing float 1-2-6 in automatic cut-off dropping funnel 1 will produce buoyancy and upwards floats, its latex seal membrane 1-2-6-4 will depart from dropping funnel and go out liquid sealing 1-2-7, medicinal liquid will go out liquid sealing 1-2-7 from dropping funnel and flow in tube for transfusion, and then flow in patient's vein blood vessel, enter transfusion state,
In transfusion process, under the combined effect of sealing float 1-2-6 and buoyancy spacing at the spacing edge 1-2-5 of float, be suspended in the spacing hollow out vestlet of float 1-2-3 always, when the medicinal liquid in medicinal liquid bottle is totally lost, when medicinal liquid face in automatic cut-off dropping funnel 1 starts to decline, sealing float 1-2-6 will decline thereupon, its latex seal membrane 1-2-6-4 will drop on dropping funnel go out liquid sealing 1-2-7 above, and it is airtight, produce cut-off, after cut-off, medicinal liquid is no longer mobile, liquid level no longer declines, there is transfusion halted state, now stay the medicinal liquid in automatic cut-off dropping funnel 1 and lower tube for transfusion 3, still maintaining certain pressure has avoided air to enter in lower tube for transfusion and anti-generation of flowing back to blood phenomenon.
If continue transfusion, continuous bottle change dressings after the operator middle and upper part that only need gently pinch automatic cut-off dropping funnel 1, then unclamp fast, automatic cut-off dropping funnel 1 will suck the medicinal liquid in medicinal liquid bottle fast, supplement lower medicinal liquid face in dropping funnel, sealing float 1-2-6 is picked up simultaneously, dropping funnel goes out liquid sealing 1-2-7 and is opened, medicinal liquid starts to flow, and enters continuation transfusion state.
Automatic cut-off dropping funnel 1 assembles one with the negative pressure threeway conduction device 3 of separate case application, forms from cut-off threeway negative pressure conduction device; After it is connected with upper tubing 2 and lower tube for transfusion 4, form disposable automatic cut-off negative pressure conduction intravenous transfusion device.Disposable automatic cut-off negative pressure conduction transfusion device, in the time that transfusion stops, can conducting negative pressure, supports corollary system work.
In process of production, the structural member in this case adopts conventional production technology to produce, and manufacturability is strong, and production cost is low; Adopt the manufacture of multimode injection moulding, production efficiency; Sealing float 1-2-6 can adopt the material that density is less to make, and to increase buoyancy, can reduce cap volume simultaneously, increases overall appearance effect; Latex seal membrane 1-2-6-4 adopts soft latex material, guarantees sealing effectiveness;
Automatic cut-off dropping funnel 1 provided by the present invention, good sealing effect, stable and reliable for performance; 1-2-6 is spacing in the liquid outlet one end in dropping funnel inside for its sealing float, does not affect formation and the observing effect of drop in dropping funnel, does not increase the volume of dropping funnel and affects outward appearance, similar or close to the traditional style of disposable general infusion set dropping funnel; Dropping funnel liquid outlet can directly connect with lower tube for transfusion, or connects with negative pressure conduction device, does not affect the flow effect of medicinal liquid, and its amount of flow is more than or equal to defined flow standard in GB.
Be equipped with disposable intravenous infusion set of the present invention, 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 feature such as manufacturability is strong; In clinical practice, can effectively reduce medical personnel's labor intensity, save a large amount of human resources who takies for observing transfusion progress, make more standard of infusion management, nurse more intimate.
