Abstract
The utility model relates to a liquid collecting device for the negative-pressure suction in medical care. The utility model comprises a bottle stopper (3), a liquid inlet pipe (2), an air pumping pipe (7), a liquid collecting bag (1), a liquid storing bag (4) and a liquid outlet (6). The utility model is matched with a glass bottle, the liquid which needs to be sucked is sucked in the liquid collecting bag, and then the liquid is flowed into the liquid collecting bag out of the bottle. The whole negative-pressure suction liquid-collecting device together with the liquid in the negative-pressure suction liquid-collecting device are disposed after the suction is finished, and the glass bottle is repeatedly used without being polluted. The utility model has the advantages of sanitation and convenience.
Description
This utility model relates to the liquid collector of using when vacuum suction is done in a kind of confession medical treatment and nursing.
Vacuum suction is the common operation in the hospital, can be with the hemorrhage absorption in secretions in the patient's body cavity or the operation process by attraction.Vacuum suction utensil at present commonly used is a high capacity vial (about 2500 milliliters), and its and a vacuum source are joined, and makes to produce a negative pressure in the bottle,, and is stored in the vial secretions or blood sucking-off by suction catheter, with complete, still needs by manually being cleaned.If meet the infectious disease of not timely diagnosis or the secretions or the blood of other especial patients, just might cause transmission of disease and popular.
The purpose of this utility model is to propose a kind of disposable medical negative pressure suction liquid collecting device.
This Dispoable medical vacuum aspiration liquid collecting device comprises liquid-collection bag, feed tube, exhaust tube, drain pipe, bottle stopper and liquid storing bag, liquid-collection bag is fixed on the inboard of bottle stopper, feed tube passes bottle stopper, inserts in the liquid-collection bag, and exhaust tube inserts in the liquid-collection bag from bottle stopper, with liquid-collection bag jack-up, and pass from the bag top, in bag and outside the bag, an opening being arranged all, the upper end of drain pipe links to each other with bottle stopper, the liquid storing bag of ining succession below, there is a check valve lower end of drain pipe.
The use that matches with a vial of this attraction liquid collecting device.Vial is inverted, the liquid-collection bag that attracts liquid collecting device is inserted in the bottle, with stopper and glass bottle opening jam-pack, exhaust tube and vacuum extractor are connected together, feed tube links to each other with suction catheter.Start vacuum extractor, just formed negative pressure in vial and the liquid-collection bag, suck liquid in the feed tube, the check valve of drain pipe lower end is closed because of negative pressure in managing, and liquid just sucks in the liquid-collection bag from feed tube.When the liquid in the liquid-collection bag reaches a certain amount of, in case stop to attract or feed tube in when entering air in certain amount, negative pressure reduces in the liquid-collection bag, liquid relies on the one-way valve opens of the gravity of self with the drain pipe lower end, enters in the liquid storing bag.After attracting to finish, liquid all flows in the liquid storing bag, transfer to bottle stopper, whole vacuum aspiration liquid collecting device can be fallen together with the liquid handling of the inside, vial is then reusable, liquid all is limited in the vacuum aspiration liquid collecting device in the whole attraction process, and vial only plays the usefulness of the certain space of maintenance with evacuation, can not polluted.
Accompanying drawing 1 is the structure chart of this Dispoable medical vacuum aspiration liquid collecting device;
Accompanying drawing 2 is a kind of structure chart of drain pipe lower end check valve;
Accompanying drawing 3 is the structure chart of another kind of check valve.
As shown in Figure 1, (1) is liquid-collection bag, and it is fixed on the inboard of bottle stopper (3).Feed tube (2) passes bottle stopper and inserts in the liquid-collection bag.Also from bottle stopper inserted liquid-collection bag, the upper end of exhaust tube passed from the top of liquid-collection bag exhaust tube (7), linked to each other with the liquid-collection bag top, with liquid-collection bag jack-up, and an opening (8), (9) was all arranged in that bag is inside and outside.The upper end of drain pipe (6) links to each other with bottle stopper.The lower end liquid storing bag (4) of ining succession, the exit, lower end of drain pipe is check valve (5).Whole vacuum aspiration liquid collecting device can be made of plastic, and wherein bottle stopper, exhaust tube, feed tube, drain pipe can be used harder plastics, and the then available flexible plastic of liquid-collection bag and liquid storing bag is made, and chain-dotted line is depicted as the vial that is used among the figure.
As shown in Figure 2, the check valve (5) in described drain pipe exit can be a plastic film cover (10), and there is an opening its lower end.When being in vacuum negative pressure condition in the liquid-collection bag, this plastic film cover is taken out flat, and the outlet of drain pipe is blocked, and when the liquid-collection bag internal pressure increased, the liquid that the inside is gathered strutted plastic film cover (10), and liquid can flow down.
Check valve (5) can also be made with several sections plastic tubes (11), (12) and bead (13) as shown in Figure 3, when being vacuum in the liquid-collection bag, bead (13) is upwards inhaled, block outlet, the liquid-collection bag internal pressure increases, bead (13) is pushed down, and liquid can flow out from the side opening (14) of plastic tube (11).
Claims (2)
1, a kind of Dispoable medical vacuum aspiration liquid collecting device, comprise bottle stopper (3), feed tube (2), exhaust tube (7), it is characterized in that it also comprises liquid-collection bag (1), liquid storing bag (4) and drain pipe (6), liquid-collection bag is fixed on the inboard of bottle stopper, feed tube passes bottle stopper and inserts in the liquid-collection bag, exhaust tube inserts in the liquid collecting liquid from bottle stopper, with liquid-collection bag jack-up, and pass from the bag top, in bag and outside the bag, an outlet is arranged all, the upper end of drain pipe links to each other with bottle stopper, the lower end liquid storing bag of ining succession, and there is a check valve (5) in the exit, lower end of drain pipe.
2, medical negative pressure suction liquid collecting device as claimed in claim 1 is characterized in that described check valve is a plastic film cover (10), and there is an opening its lower end.
