Abstract
The utility model relates to a negative pressure sucking liquid gathering device for doctors for carrying out negative pressure sucking operation. The utility model comprises a rigid bottle body 1 which is provided with a liquid outlet 5, a negative pressure source interface 3 and a liquid inlet 2, a drain pipe 6 is connected to a liquid outlet, a one-way valve 8 is arranged on the lower part of the drain pipe and a plastic bag 9 with large capacity is sheathed on the lower part of the drain pipe. The utility model can be used for collecting blood, pus, secretion, etc. in body cavities of patients in the plastic bag by the suction of the bottle body and for operation or patient nursing operation and can be made into a disposable product.
Description
This utility model relates to the apparatus that a kind of doctor of confession carries out the vacuum suction operation, a kind of vacuum aspiration liquid collecting device.
After the vacuum suction apparatus system that generally uses in the hospital is at present connected by two jumbo vials, one end is connected with negative pressure source, the other end links to each other with patient's body cavity by attraction pipeline, attracts blood, pus, secretions and other dunghill in the patient's body cavity.After each use finishes, need pour out, clean then, sterilize, expend more man power and material by the dirt that the medical worker stays collection in the vial.If during the especial patients such as infectious disease of meeting and failing to clarify a diagnosis, just iatrogenic cross infection might take place.
The purpose of this utility model is the structure that proposes a kind of vacuum aspiration liquid collecting device.
This vacuum aspiration liquid collecting device comprises the bottle of a rigidity negative pressure source interface and inlet being arranged on the bottle, and there is a liquid outlet lower end, is connecting discharging tube, and there is a check valve lower end of discharging tube.
When this vacuum aspiration liquid collecting device uses, bottle is hung on the place of certain altitude, the discharging tube outlet is inserted in the big container, the negative pressure source interface links to each other with negative pressure source, connects suction catheter on the inlet, can attract to operate.After negative pressure source started, the check valve of discharging tube lower end was subjected to suction function and closes automatically, and suction catheter just can suck sucked liquid in the bottle.Enter the intravital liquid of bottle and rely on deadweight to flow to the bottle bottom, enter in the discharging tube from liquid outlet.Fluid accumulation in discharging tube is to certain height, and the pressure of fluid column is with one-way valve opens, in the container below liquid just flows into automatically.Continue this moment to attract, the liquid of being inhaled just constantly flows into through bottle in the container under the discharging tube, can be not too much in the bottle inner accumulated.When suction catheter is plugged, when negative pressure increased in the bottle, the check valve of discharging tube outlet was promptly closed automatically, thereby the liquid that can not suck-back is gone in the bottle.This vacuum aspiration liquid collecting device is because the volume of bottle can be less, such as, 300～500 milliliters of sizes get final product, and materials are province relatively just, can make disposable device.Bottle generally can be made of the transparent plastic of hard.
Accompanying drawing is the structure chart of this vacuum aspiration liquid collecting device.
As shown in the figure, this vacuum aspiration liquid collecting device comprises the bottle 1 of rigidity, the opening 3 at bottle top is the negative pressure source interface, opening 2 on the sidewall is an inlet, the opening of lower end is a liquid outlet 5, is connecting discharging tube 6, and there is a check valve 8 at 7 places, lower end of discharging tube, this check valve is open-minded downwards, upwards closes.The structure of check valve can be ball a---spring structure, is a bit of elastic soft tube shown in the figure.Jumbo plastic film bag 9 can overlapped in the discharging tube lower end, and the container as collecting liquid can hold more liquid, and the disposable use of entire device prevents that the effect of cross infection is just better.
As shown in the figure, can also have one to hang the little hook 4 of usefulness on the bottle 1, be convenient to bottle and hang.In addition, the diameter of liquid outlet 5 helps the intravital liquid of bottle and flows in the plastic bag smoothly greater than the diameter of inlet 2.
Claims (3)
1, a kind of vacuum aspiration liquid collecting device, the bottle (1) that comprises a rigidity has negative pressure source interface (3) and inlet (2) above, it is characterized in that there is a liquid outlet (5) the bottle lower end, liquid outlet is connecting discharging tube (6), and the lower end of discharging tube (7) have a check valve (8).
2, vacuum aspiration liquid collecting device as claimed in claim 1 is characterized in that a jumbo plastic film bag (9) is also being overlapped in the lower end of discharging tube (6).
3, vacuum aspiration liquid collecting device as claimed in claim 1 or 2 is characterized in that described bottle (1) upward also has one to hang the little hook (4) of usefulness, and the diameter of described liquid outlet (5) is greater than the diameter of inlet (2).
