Abstract
The utility model discloses a double-channel injector. The utility model is composed of a needle cylinder (1) and an inner core (2), wherein, the needle cylinder is provided with two channels (4) and (5), each channel of the two channels is provided with a one-way valve, the one-way valves are provided with opposite directions and are opened by air thrust. The utility model can realize continuous extraction and discharge of hydrothorax and ascites, air exhaustion of closed pneumothorax punctures, pressure transfusion, cleanness of open body cavities and deeper wounds, suction of amniotic fluid in an oral cavity and a respiratory tract of newborn babies, and sputum suction and oral cavity cleanness of coma patients.
Description
This utility model relates to a kind of syringe.
The syringe that uses at present is single channel, and its finite capacity and fixing can not be realized continuous suction action, as suction to hydrothorax ascites, take off syringe after can only being pumped to the fixed amount of syringe, discharge and connect syringe again behind the aspirate and aspirate, move discontinuous.
The purpose of this utility model is a kind of syringe that can carry out the suction action continuously of design.
This utility model syringe is made up of syringe (1) and inner core (2), and two passages (4,5) are arranged on the syringe, and two passages respectively have direction check valve opposite and that opened by air thrust.
This utility model can be realized the continuous extraction of hydrothorax ascites, and the closed pneumothorax puncture is bled.When extracting hydrothorax ascites, plunger (2) is drawn back, piston (6) closing passage (5), and hydrothorax ascites is by being evacuated to syringe through passage (4) in the body; Plunger is pushed ahead, and piston (3) is subjected to air thrust closing passage (4), and hydrothorax ascites is discharged by passage (5).
Equally, this utility model can carry out following operation:
1, pressure transfusion is particularly suited for importing at short notice the situation of big quantity of fluid, and can accurately controls input speed.
2, open body cavities reaches and cleans than gash.Can pressurize to wash continuously and improve cleaning performance, and can save cleaning liquid greatly.
3, amniotic fluid in sucking-off neonate oral cavity and the respiratory tract; Coma patient is inhaled expectorant and oral cavity cleaning.
4, disposable dual pathways syringe portably uses conveniently, is particularly useful for some special environment, as the battlefield, and rescue and relief work, and do not possess situation such as sterilization supply condition.
Accompanying drawing is this utility model structural representation.
This utility model embodiment as shown in drawings, piston (3) can be by air thrust closed channel (4), piston (6) can be by air suction closed channel (5).
Claims (1)
1, a kind of dual pathways syringe is made up of syringe (1) and inner core (2), it is characterized in that having on the syringe two passages (4,5), and two passages respectively have direction check valve opposite and that opened by air thrust.
