Abstract
The utility model belongs to the field of medical appliances, and particularly relates to a disposable infusion set capable of automatically stopping the infusion and exhausting the air. The infusion set comprises a drip chamber, the drip chamber is formed by an upper cover, a dripper chamber main body and a base, which is characterized in that: an infusion stopping filter film is arranged in the base, the outer edge of the infusion stopping filter film is welded on the inner wall of the base, the base is a hard base, an exhaust hole used for communicating the inner cavity of the drip chamber with the atmosphere is arranged on the wall of the base, and an exhaust piece is arranged on the drip chamber inner cavity end of the exhaust hole. The disposable infusion set has a simple and reasonable structure, the base and the infusion stopping filter film commonly form the automatic infusion stopping structure, and the infusion is automatically stopped after infusion of the medical liquid is finished; the exhaust hole on the base and the exhaust piece commonly form the automatic exhaust structure, and the air is automatically exhausted during the infusion process, and the air bubbles are prevented from entering into the infusion duct, so that the disposable infusion set is safe and convenient to use, and facilitates the treatment on clinical patients.
Description
Technical field
This utility model relates to a kind of disposable automatic liquid-stopping automatic-exhaust transfusion device, belongs to medical instruments field.
Background technology
At present, hospital carries out venous transfusion or when blood transfusion to clinical patients, generally uses disposable transfusion device, like this, and to preventing that the cross infection between patient from having played useful effect.Yet, use this disposable transfusion device also to exist weak point, be that current disposable transfusion device is after medicinal liquid infusion-completed, because there is no automatic-diversion closure function, to change in time medicinal liquid bottle (bag) or pull out transfusion needle, otherwise air will enter transfusion catheter, can bring unsafe factor to patient, be unfavorable for the treatment of clinical patients; In addition, when transfusion device herb liquid starts to enter dropping funnel, very easily form the mixture of gas and liquid, this gas-liquid mixture can enter rapidly in the infusion pipeline of dropping funnel below, bubble phenomenon while forming transfusion, the healthy of patient threatened, so medical personnel are when transfusion, after the bubble in transfusion catheter must being discharged completely, infuse again.Conventionally the method adopting is, bottle plug puncture unit is being thrust after transfusion bottle stopper, be inverted or extruding dropping funnel, medicinal liquid is entered in dropping funnel, in dropping funnel, be filled with half left and right liquid after rapidly dropping funnel is returned to normal operating condition again, nonetheless, on tube wall, also often adsorb bubble, also need medical personnel to pinch bubble with finger bullet, this kind of operational approach is comparatively loaded down with trivial details, to medical personnel, brings great inconvenience.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of rational in infrastructure, simple and efficient to handle and safe and reliable disposable automatic liquid-stopping automatic-exhaust transfusion device is provided.
Disposable automatic liquid-stopping automatic-exhaust transfusion device described in the utility model, comprise dropping funnel, dropping funnel is formed by upper cover, dropping funnel body and base combination, only liquid filter membrane is set in base, the only outward flange of liquid filter membrane and base inner wall welding, base adopts hard base, and the steam vent that is communicated with dropping funnel inner chamber and ambient atmosphere is set in base wall, and the dropping funnel inner chamber end of steam vent is provided with exhaust part.
Wherein, exhaust part is hydrophobic air filter membrane, and exhaust part is welded on base.
In the dropping funnel of this transfusion device, only liquid filter membrane is by being welded and fixed position in base, and hard base, only liquid filter membrane forms automatic liquid-stopping structure jointly; Base wall is provided with steam vent, and exhaust part is welded on base, by exhaust part and steam vent, jointly forms automatic exhausting equipment, prevents bubble to bring in transfusion catheter.
Only liquid filter membrane can intercept air after infiltrating and passes through, and plays automatic liquid-stopping function, thereby needn't worry that liquid walks sky.When many bottle liquid medicines of infusion, even do not change second bottle in time after the first bottle liquid medicine infused, when liquid flows in filter, owing to stopping liquid filter membrane, can separate air force liquid to stop flowing, avoid medicinal liquid to continue to walk sky, thereby avoided patient to occur blood back phenomenon.And after changing new bottle due to the steam vent on hard base wall from degassing function, the air that upstream can be got off is discharged automatically, thereby can make dropping funnel automatic liquid feeding and without manual operation, thus assurance can continue normal infusion.
The beneficial effect that this utility model compared with prior art had is:
This disposable automatic liquid-stopping automatic-exhaust transfusion device is simple and reasonable, and base, only liquid filter membrane forms automatic liquid-stopping structure jointly, after medicinal liquid infusion-completed, realizes automatic liquid-stopping; Steam vent on base, exhaust part form automatic exhausting equipment jointly, can automatic vent in infusion process, prevent bubble to bring in transfusion catheter, and safe and convenient to use, be conducive to the treatment to clinical patients.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, protective sleeve; 2, bottle plug puncture unit; 3, air inlet part; 4, transfusion catheter; 5, upper cover; 6, dropping funnel body; 7, exhaust part; 8, steam vent; 9, base; 10, stop liquid filter membrane; 11, conduit; 12, flow regulator; 13, modular connection; 14, venoclysis needle.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, this disposable automatic liquid-stopping automatic-exhaust transfusion device, automatic liquid-stopping automatic-exhaust transfusion device, comprise protective sleeve 1, bottle plug puncture unit 2, air inlet part 3, transfusion catheter 4, dropping funnel, conduit 11, flow regulator 12, modular connection 13 and venoclysis needle 14, dropping funnel is by upper cover 5, dropping funnel body 6 and base 9 combine, upper cover 5 and base 9 are arranged on respectively the upper of dropping funnel body 6, lower two ends and respectively with transfusion catheter 4, conduit 11 connects, the steam vent 8 that is communicated with dropping funnel inner chamber and ambient atmosphere is set on the wall of base 9, the dropping funnel inner chamber end welding exhaust part 8 of steam vent 8, only liquid filter membrane 10 is set in base 9, the only outward flange of liquid filter membrane 10 and base 9 inwall welding, base 9 adopts hard base.
During use; take off protective sleeve 1; bottle plug puncture unit 2 is inserted in medicinal liquid bottle or Blood bottle; liquid flows in dropping funnel through transfusion catheter 4; through stopping liquid filter membrane 10, then, in inflow catheter 11, utilize the flow velocity of flow regulator 12 scalable liquid; pass through again modular connection 13, finally by venoclysis needle 14, flow out.In the dropping funnel of this transfusion device, only liquid filter membrane 10 is by being welded and fixed position in base 9, and hard base 9, only liquid filter membrane 10 is common forms automatic liquid-stopping structure; Steam vent 8 in base wall, the common formation automatic exhausting equipment of exhaust part 7, prevent bubble to bring in conduit 11, and the exhaust part 8 in the present embodiment adopts hydrophobic air filter membranes.
