Description
Technical field
This utility model belongs to technical field of medical instruments, particularly relates to the drainage system that a kind of negative pressure is adjustable, easy to use.
Background technology
Because a lot of patient's Post operation internal organs wound is not effectively healed, now various liquid can be accumulated at intraperitoneal.The most common is exactly in clinical, in order to ensure that intestinal patient after surgery can rehabilitation as early as possible, just needs the Digestive system of the low pH value from stomach to excrete by drainage device.Current domestic and international market use usually disposable vacuum suction bag or mechanical type suction pump are drained to by body fluid external.But the negative pressure that this method produces is also unstable, and the pressure of attraction may have a greater change, and causes the effect of vacuum suction undesirable, even there is refluence phenomenon, and only have a drainage bag, existing drainage system function singleness, well can not coordinate operation, be further improved.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of negative pressure drainage system adjustable, easy to use, can regulate the pressure in drainage bag, and refluence phenomenon can not occur according to practical situation.
To achieve these goals, this utility model adopts following technical scheme:
A kind of negative pressure is adjustable, drainage system easy to use, comprise inner the first drainage bag for vacuum, described first drainage bag is connected with drainage tube, described drainage tube end is provided with draining hole, described first drainage bag top is provided with air vent, the bottom of described first drainage bag is provided with Outlet check valves, characterized by further comprising the second drainage bag, anti-down suction pipe, described second drainage bag is connected with described drainage tube, and be positioned near described first drainage bag, described second drainage bag inside is vacuum state, between described second drainage bag and described drainage tube, this has the first control valve, described anti-down suction pipe is provided with in described first drainage bag, described anti-down suction pipe one end is through being connected with described first drainage bag sealed bottom bottom described first drainage bag, the other end is positioned at described first drainage bag and Open Side Down.
Described second drainage bag is connected with negative pressure adapter by negative tube, and described negative tube is provided with the second control valve.
Described anti-down suction pipe is the pipe of inverted U.
Described first drainage bag is inwardly provided with the tooled joint of two longitudinal directions, arc from dual-side.
Described first drainage bag, described second drainage bag are respectively equipped with graduation mark.
Sealing-plug is provided with through the anti-suck tube portion bottom described first drainage bag.
Be positioned at the opening of the described anti-down suction pipe of described first drainage bag inside and the distance of described first draft tube bottom is 10-25mm.
The beneficial effects of the utility model are: the second drainage bag is vacuum state, can also be connected with negative pressure adapter, can be not only that the negative pressure of the first drainage bag regulates, the effect of slow pressure can also be played when pressure is large, when draining fluids is more, the second drainage bag can be used as general drainage bag and uses; Anti-down suction pipe plays the effect preventing draining fluids from returning human body, and when the first drainage bag pressure is very large, liquid is pressed into anti-down suction pipe, and the restriction of distance is convenient to will prevent liquid suck-back better; First drainage bag is provided with tooled joint, and the centre of the first drainage bag is divided into three equal parts sack from longitudinally, and when carrying liquid, just liquid can be divided into multiple region, just not have the phenomenon that liquid sinks protrudes outward, patient is more convenient when carrying.This utility model structure is simple, and effectively can prevent the suck-back in operation process, and can regulate negative pressure, patient is easy to use, painful little.

Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of detailed description of the invention of the present utility model is explained.
As Fig. 1, shown in Fig. 2, this utility model provides a kind of negative pressure adjustable, drainage system easy to use, comprise the first drainage bag 1, described first drainage bag 1 is connected with drainage tube 2, described drainage tube 2 end is provided with draining hole 3, described first drainage bag 1 top is provided with air vent 4, the bottom of described first drainage bag 1 is provided with Outlet check valves 5, characterized by further comprising the second drainage bag 6, anti-down suction pipe 7, described second drainage bag 6 is connected with described drainage tube 2, and be positioned near described first drainage bag 1, the first control valve 8 is provided with between described second drainage bag 6 and described drainage tube 2, described second drainage bag 6 is connected with negative pressure adapter 10 by negative tube 9, second drainage bag 6 provides and adjusting device as a negative pressure, it is vacuum state in it, simultaneously also as Assist drainage device, described negative tube 9 is provided with the second control valve 11, the pipe of inverted U is provided with as anti-down suction pipe 7 in described first drainage bag 1, the height at anti-down suction pipe 7 two ends is different, described anti-down suction pipe 7 one end is through being connected with described first drainage bag 1 sealed bottom bottom described first drainage bag 1, the other end is positioned at described first drainage bag 1 and Open Side Down, and be provided with the sealing-plug 12 being positioned at the first drainage bag 1 outside.
Described first drainage bag 1 is inwardly provided with the tooled joint 13 of two longitudinal directions, arc from dual-side.The centre of the first drainage bag 1 is divided into three equal parts from longitudinal direction, form the cavity that upper and lower left, center, right is through, such sack, when carrying liquid, just can be divided into multiple region liquid, just do not have the phenomenon that liquid sinks protrudes outward, patient is just more convenient when carrying.
Described first drainage bag 1, described second drainage bag 6 are respectively equipped with graduation mark 14.
The distance be positioned at bottom the opening of the described anti-down suction pipe 7 of described first drainage bag 1 and described first drainage tube 2 is preferably 10-25mm.
During use, drainage tube 2 inserts body operation position, drainage-fluid flows into the first drainage bag 1 along drainage tube 2, when the negative pressure in the first drainage bag 1 is not enough, opens the first control valve 8 and be communicated with in the second drainage bag 6, second drainage bag 6 and have certain negative pressure, suck-back can be prevented to a certain extent, when second drainage bag 6 negative pressure is lower, can open the second control valve 11, negative pressure adapter 10 can provide negative pressure; Also or when the pressure height of the first drainage bag 1 in drainage process, the second drainage bag 6 can be used as slow pressure device; After first drainage bag 1 filled with fluid, the second drainage bag 6 can be used as general drainage bag and uses.When second drainage bag 6 uses as negative pressure generator, occurring that the negative pressure of emergency situations as brief power outage in the first drainage bag 1 can play the effect of negative pressure adapter 10 time not enough, ensure that the safety of patient.
Above an example of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to this utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
