Abstract
The utility model provides a disposable automatic exhaust infusion component for use in infusion. The infusion component consists of a liquid inlet tube (1), a liquid inlet (11), a liquid-gas separating disk (2), an exhaust hole (21), a liquid outlet tube (3) and a liquid outlet (31). During use, the disposable automatic exhaust infusion component is connected behind a liquid medicament filter of an ordinary infusion set, air is automatically separated from a liquid medicament after entering the liquid-gas separating disk (2) from the liquid inlet tube (1), air is exhausted in a single direction from the exhaust hole (31), and the liquid medicament enters a human body from the liquid outlet tube, so that an entire automatic exhaust process is completed, and the automatic exhaust function of an infusion set terminal is realized.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of disposable use automatic vent infusion part.
Background technology
Transfusion device is the medical apparatus and instruments of quantity maximum, and general infusion set can only be discharged at the pin place of connecing the air that enters below the Murphy type burette, exists the possibility of air embolism, liquid medicine contamination.At present clinically progressively adopt a kind of automatic-exhaust transfusion device (China Patent No.: 91214967.1 ZL03250374.1), this automatic-exhaust transfusion device is that adjunction liquid device separator and an exhaustor reach the purpose that automatic discharge enters the transfusion inner air tube on general infusion set and common infusion set.But must be in the stand up position state during liquid device separator air-discharging of this transfusion device, can not satisfy clinical situation complicated and changeable.00223155.7), but because complex structure does further improvement for this reason, designed a kind of device (patent No.:, manufacture difficulty and can't finish.
Summary of the invention
This utility model purpose provides a kind of disposable use automatic vent infusion part, the transfusion inner air tube can be discharged automatically from the transfusion device terminal during transfusion, strengthens the safety of transfusion patient.
The technical scheme that its technical problem that solves this utility model adopts is: disposable use automatic vent infusion part mainly is comprised of feed tube, inlet, liquid edema caused by disorder of QI separation disc, steam vent, drain pipe, liquid outlet.Behind the general infusion set liquid medicine filter, connect disposable use automatic vent infusion part during use, when air enters liquid edema caused by disorder of QI separation disc from feed tube, air is discharged from steam vent, liquid enters human body from drain pipe, thereby finished the automatic vent overall process, realized in the self-bleeding function of transfusion device terminal.
The beneficial effects of the utility model are: disposable use automatic vent infusion part can be discharged the air in the transfusion organ pipe from the transfusion device terminal automatically, overcoming existing general infusion set can not self-bleeding drawback, overcome the restriction that original automatic-exhaust transfusion device liquid-gas separator when air-discharging must be in erectility, optimize automatic ventilating function, can satisfy clinical situation complicated and changeable.This utility model can effectively prevent the air intravasation, and the possibility of avoiding air embolism to occur does not need air is guarded processing in infusion process, has further strengthened the safety of transfusion patient, has improved medical worker's work efficiency.Its effect is safe and reliable, simple to operate, and definite application value is arranged.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments.
Accompanying drawing is structural representation of the present utility model.
1 feed tube, 11 inlets, 2 liquid edema caused by disorder of QI separation discs, 21 steam vents, 3 drain pipes, 31 liquid outlets among the figure
The specific embodiment
This utility model is comprised of feed tube 1, inlet 11, liquid edema caused by disorder of QI separation disc 2, steam vent 21, drain pipe 3, liquid outlet 31.Feed tube 1 connecting fluid edema caused by disorder of QI separation disc 2 one ends, the other end of liquid edema caused by disorder of QI separation disc 2 connects drain pipe 3, and liquid edema caused by disorder of QI separation disc 2 central authorities are steam vents 21.Liquid outlet 31 all has automatic ventilating function in inlet 11 1 sides in all cases to guarantee disposable automatic vent infusion part.Each parts all selects medical macromolecular materials to make, and wherein steam vent 21 is selected medical hydrophobic membrane, has guaranteed the unidirectional discharge of air in the tube for transfusion, prevents that atmospheric air from entering.
Behind the general infusion set liquid medicine filter, connect disposable use automatic vent infusion part during use, because water and air specific weight differ, when air enters liquid edema caused by disorder of QI separation disc from feed tube, air separates automatically with medicinal liquid, air is from the unidirectional discharge of steam vent, medicinal liquid enters human body from drain pipe, thereby has finished the automatic vent overall process, has realized in the self-bleeding function of transfusion device terminal.
Claims (1)
1. disposable use automatic vent infusion part is comprised of feed tube (1), inlet (11), liquid edema caused by disorder of QI separation disc (2), steam vent (21), drain pipe (3), liquid outlet (31), it is characterized in that: feed tube (1) connecting fluid edema caused by disorder of QI separation disc (2) one ends, the other end of liquid edema caused by disorder of QI separation disc (2) connects drain pipe (3), liquid outlet (31) is in inlet (11) one sides, and liquid edema caused by disorder of QI separation disc (2) central authorities are steam vent (21).
