Abstract
The utility model belongs to the field of medical instruments, and particularly relates to an automatic liquid stop and automatic exhaust infusion apparatus. The infusion apparatus comprises a dripping bucket, and is characterized in that a floating body is arranged in the dripping bucket, a sealing film capable of moving freely is arranged in the floating body, the sealing film is communicated with the outside through an opening in the bottom of the floating body, the dripping bucket consists of an upper cover, a dripping bucket body and a hard base, the base is provided with an exhaust hole for communicating the inner cavity of the dripping bucket with the external atmosphere, and an inner cavity end of the dripping bucket of the exhaust hole is provided with an exhaust piece. The automatic liquid stop and automatic exhaust infusion apparatus has a simple and reasonable structure, an automatic liquid stop structure is formed by the base, the floating body and the sealing film together, and automatic liquid stop is realized after the medicine liquid infusion is completed; and an automatic exhaust structure is formed by the exhaust hole and the exhaust piece on the base together, automatic exhausting can be realized in the infusion process, air bubbles are prevented from being taken into an infusion catheter, and the infusion apparatus is safe and convenient to use, and is conductive to the treatment on clinical patients.
Description
Technical field
This utility model relates to a kind of liquid automatic-exhaust transfusion device that ends automatically, belongs to the medical instruments field.
Background technology
At present, when hospital carries out venous transfusion or blood transfusion to clinical patients, generally use disposable transfusion device, like this, played useful effect to preventing the cross infection between the patient.Yet, use this disposable transfusion device also to exist weak point, be that current disposable transfusion device is after the medicinal liquid transfusion finishes, because there not being the automatic-diversion closure function, will in time change dressings liquid bottle (bag) or pull out transfusion needle, can bring unsafe factor to the patient otherwise air will enter transfusion catheter, be unfavorable for the treatment of clinical patients; In addition, when the transfusion device herb liquid begins to enter dropping funnel, very easily form gas and mixtures of liquids, this gas-liquid mixture can enter rapidly in the infusion pipeline of dropping funnel below, bubble phenomenon when forming transfusion, the healthy of patient threatened, so medical personnel infuse after the bubble in the transfusion catheter must being discharged fully when transfusion again.Usually the method that adopts is, after bottle plug puncture unit is thrust transfusion bottle stopper, be inverted or the extruding dropping funnel, medicinal liquid is entered in the dropping funnel, behind the liquid that charges in the dropping funnel about half, rapidly dropping funnel is returned to normal operating condition again, nonetheless, also often adsorb bubble on the tube wall, also need medical personnel to pinch bubble with the finger bullet, this kind operational approach is comparatively loaded down with trivial details, brings great inconvenience to medical personnel.
The 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 simple in structure, easy to use and safe and reliable automatic liquid automatic-exhaust transfusion device that ends is provided.
The technical scheme that its technical problem that solves this utility model adopts is: the described liquid automatic-exhaust transfusion device that ends automatically, comprise dropping funnel, be provided with buoyancy aid in the dropping funnel, the inside of buoyancy aid is provided with the sealed film that can move freely, sealed film communicates with the external world by the opening of buoyancy aid bottom, dropping funnel is combined by loam cake, dropping funnel body and hard base, and the steam vent that is communicated with dropping funnel inner chamber and ambient atmosphere is set on the base, and the dropping funnel inner chamber end of steam vent is provided with exhaust part.
In the dropping funnel of this transfusion device, buoyancy aid bottom by rivet welding with the sealed film fixed position in buoyancy aid, base, buoyancy aid, the common formation of sealed film are ended the liquid structure automatically, after the medicinal liquid transfusion finishes, after being whole outflow of medicinal liquid in the dropping funnel, buoyancy aid can fall to the bottom of dropping funnel automatically, and the sealed film of buoyancy aid bottom realizes ending automatically liquid with the transfusion catheter sealing that the dropping funnel bottom connects; Steam vent on the base, exhaust part constitute the automatic vent structure jointly, prevent from bubble is brought in the transfusion catheter.
Wherein:
Described base upper end rivet welding limited block prevents that the excessive height of buoyancy aid come-up from stopping up the inlet of dropping funnel.
Described exhaust part is the hydrophobic air filter membrane, and exhaust part is welded on the base.
The beneficial effects of the utility model are:
It is simple and reasonable that this ends the liquid automatic-exhaust transfusion device automatically, and base, buoyancy aid, sealed film formation jointly end the liquid structure automatically, and realization ended liquid automatically after the medicinal liquid transfusion finished; Steam vent on the base, exhaust part constitute the automatic vent structure jointly, can automatic vent in the infusion process, prevent from bubble is brought in the transfusion catheter, and safe and convenient to use, be conducive to the treatment to clinical patients.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, protective sleeve; 2, bottle plug puncture unit; 3, air inlet part; 4, transfusion catheter; 5, loam cake; 6, dropping funnel body; 7, limited block; 8, exhaust part; 9, steam vent; 10, base; 11, buoyancy aid; 12, sealed film; 13, transfusion catheter; 14, flow regulator; 15, liquid medicine filter; 16, 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; automatically end the liquid automatic-exhaust transfusion device; comprise protective sleeve 1; bottle plug puncture unit 2; air inlet part 3; transfusion catheter 4; dropping funnel; buoyancy aid 11; transfusion catheter 13; flow regulator 14; liquid medicine filter 15 and venoclysis needle 16; dropping funnel is by loam cake 5; dropping funnel body 6 and hard base 10 combine; loam cake 5 and base 10 be installed in respectively dropping funnel body 6 on; following two ends and respectively with transfusion catheter 4; 10 connect; the steam vent 9 that is communicated with dropping funnel inner chamber and ambient atmosphere is set on the base 10; the dropping funnel inner chamber end welding exhaust part 8 of steam vent 9; buoyancy aid 11 is arranged in base 10; but be provided with the sealed film 12 that easy on and off moves in the buoyancy aid 11; buoyancy aid 11 bottoms by rivet welding with sealed film 12 fixed positions in buoyancy aid 11; sealed film 12 communicates with the external world by the opening of buoyancy aid 11 bottoms; base 10 upper end rivet welding limited blocks 7 prevent that the excessive height of buoyancy aid 11 come-up from stopping up the inlet of dropping funnel.
During use; take off protective sleeve 1; bottle plug puncture unit 2 is inserted in medicinal liquid bottle or the Blood bottle; liquid flows in the dropping funnel through transfusion catheter 4; buoyancy aid 11 floats, and flows into then in the transfusion catheter 13, utilizes the flow velocity of flow regulator 14 scalable liquid; pass through liquid medicine filter 15 again, finally flow out by venoclysis needle 16.In the dropping funnel of this transfusion device, base 10, buoyancy aid 11, sealed film 12 common formations are ended the liquid structure automatically, after the medicinal liquid transfusion finishes, after being whole outflow of medicinal liquid in the dropping funnel, buoyancy aid 11 can fall to the bottom of dropping funnel automatically, the sealed film 12 of buoyancy aid 11 bottoms realizes ending automatically liquid with transfusion catheter 13 sealings that the dropping funnel bottom connects; Steam vent 9 on the base 10, exhaust part 8 common formation automatic vent structures prevent from bubble is brought in the transfusion catheter 13, and the exhaust part 8 in the present embodiment selects the hydrophobic air filter membrane.
