The one-way valve comprises a valve seat and a valve cover which is fixedly connected with the valve seat. A valve cavity is formed between the valve seat and the valve cover. The valve cover is provided with a liquid inflow channel which is communicated with the valve cavity. The valve seat is provided with a liquid outflow channel which is arranged to directly face to the liquid inflow channel. The interior of the valve cavity is provided with the central membrane which prevents liquid from flowing adversely. The edge of the central membrane is provided with a plurality of through holes. The valve seat is provided with a plurality of supporting projections which are located at the surrounding of the inlet of the liquid outflow channel. The accessory provided by the utility model employs the one-way valve disposed at the part, at the liquid inflow end of the infusion cavity, of the housing, thereby preventing the medicine liquid from flowing adversely under the pressure during the adding of medicine. The accessory provided by the utility model employs the medicine liquid filter disposed at the part, at the liquid outflow end of the infusion cavity, of the housing, can filter particles in the medicine liquid, and effectively lock an intravenous infusion needle.
Description
Technical field
This utility model relates to a kind of medical apparatus, particularly a kind of Quick-adding medicine accessory.
Background technology
At present clinically in when transfusion, by injection member, to injectable drug in transfusion device, from patient end, distant and medicinal liquid enters after tube for transfusion by injection member injection member, under pressure easy upruss; For need fast injection medicinal liquid patient, there is the patient of infusion reaction and the patient of first aid, if injection member, from patient apart from too far away, can cause the waste of rescue time, simultaneously, if accessory can make the weight of transfusion device increase too much on transfusion device, be unfavorable for the packing of product and deposit.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, proposes a kind of medicinal liquid generation adverse current while stoping dosing, can enter fast the Quick-adding medicine accessory of human body.
The technical problems to be solved in the utility model is achieved through the following technical solutions.This utility model is a kind of Quick-adding medicine accessory, be characterized in: comprise a housing with transfusing chamber, on the housing of transfusing chamber liquid outlet, be provided with the liquid medicine filter with outer cone locked joints, on the housing of transfusing chamber liquid feeding end, be provided with check valve, the valve gap that check valve comprises valve seat and is fixedly connected with valve seat, between valve seat and valve gap, be provided with valve pocket, on valve gap, be provided with the feed pathway communicating with valve pocket, on valve seat, be provided with feed pathway just to the liquid outlet channel arranging, in valve pocket, be provided with the middle diaphragm that prevents liquid countercurrent, be provided with several through holes at the edge of middle diaphragm, on valve seat, be provided with some support protrusion around liquid outlet channel entrance, on the sidewall of housing, be provided with needleless connector.
In a kind of Quick-adding medicine accessory of this utility model technical scheme, further preferred technical scheme feature is:
1, described needleless connector comprises connection body and Bacteria-prevention cap, is provided with in the outer end that connects body the union joint coordinating with Bacteria-prevention cap, connects in body and is provided with sealing member in a side of union joint.
2, described sealing member is provided with the nosing of protruding union joint, and the diameter of section of nosing is larger than the internal diameter of tube body of union joint.
3, the through hole of described middle diaphragm is circular or square or rhombus.
4, described through hole is uniformly distributed.
5, described support protrusion is evenly distributed.
Compared with prior art, this utility model utilization is arranged on the check valve on transfusing chamber liquid feeding end housing, the adverse current of medicinal liquid under pressure-acting can effectively stop dosing time; Utilization is arranged on the liquid medicine filter with outer cone locked joints on transfusing chamber liquid outlet housing, and the microgranule in can filtering liquid medicine effectively locking venoclysis needle, prevent from making because pressure is excessive venoclysis needle to disconnect in the time of dosing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands this utility model further, and do not form the restriction of its power.
Embodiment 1, with reference to Fig. 1, a kind of Quick-adding medicine accessory, comprise a housing 1 with transfusing chamber, on the housing of transfusing chamber liquid outlet, be provided with the liquid medicine filter 7 with outer cone locked joints 8, on the housing of transfusing chamber liquid feeding end, be provided with check valve 4, the valve gap that check valve 4 comprises valve seat and is fixedly connected with valve seat, between valve seat and valve gap, be provided with valve pocket, on valve gap, be provided with the feed pathway communicating with valve pocket, on valve seat, be provided with feed pathway just to the liquid outlet channel arranging, in valve pocket, be provided with the middle diaphragm 3 that prevents liquid countercurrent, be provided with several through holes at the edge of middle diaphragm, on valve seat, be provided with some support protrusion 2 around liquid outlet channel entrance, on the sidewall of housing, be provided with needleless connector.Diaphragm 3 in the middle of described support protrusion 2 can support, is not blocked liquid outlet channel by middle diaphragm 3, the position of support protrusion 2 is uniformly distributed around liquid outlet channel entrance; In the middle of described, diaphragm 3 is arranged in valve pocket and its external diameter of a circle is slightly less than the diameter of valve pocket, the mid portion of middle diaphragm is solid section, in the time having medicinal liquid adverse current, due to pressure between move and block feed pathway on diaphragm, just can effectively stop medicinal liquid adverse current; In the time of medicinal liquid forward flow due to pressure between diaphragm move down, support protrusion 2 prop up in the middle of diaphragm 3, medicinal liquid, by the through hole above middle diaphragm and space proper flow around, just can stop medicinal liquid adverse current effectively.The liquid medicine filter 7 of described outer cone locked joints 8 can directly effectively lock venoclysis needle, prevents from making because pressure is excessive venoclysis needle to disconnect in the time of dosing.
