Abstract
The utility model discloses a drainage bag which comprises a drainage bag body used for storing drainage liquid. A drainage bag connecting tube is arranged above the drainage bag body and connected with a urinary catheter. The drainage bag is characterized in that a one-way valve is arranged on the drainage bag connecting tube and only allows liquid and gas to flow into the drainage bag body; a discharging catheter is arranged below the drainage bag body, and a discharging valve is arranged at the lower end of the discharging catheter; an air catheter is further arranged above the drainage bag body and communicated with outside air, an air catheter valve is arranged on the air catheter, when the liquid in the drainage bag is discharged, the air catheter valve and the discharging valve are opened, internal and external air pressure difference of the drainage bag body is balanced, and therefore the discharging speed is increased.
Description
Technical field
This utility model relates to a kind of drainage bag, belongs to medical instruments field.
Background technology
General drainage bag, comprises the drainage bag main body that stores drainage-fluid at present, and drainage bag main body top is provided with drainage bag connection tube, and described drainage bag connection tube is connected with urinary catheter, and drainage bag below is provided with vent valves, for sampling or discharge drain.
In order to stop drainage-fluid to backflow, general drainage bag down discharge valve is generally check valve, only allows liquid outwards to discharge, and does not allow gas and liquid to backflow.Although this design has guaranteed the safe handling of drainage bag, when fluid discharge, because drainage bag main body inner and outer air pressure is poor, fluid discharge speed is slower, and usually can not be emptying all liq in bag, and mass rate of emission is uncontrollable, causes and uses inconvenience.
Summary of the invention
This utility model is in order to make up the defect of prior art, provides a kind of and can control fluid discharge speed in drainage bag, and the effective novel drainage bag of evacuation of liquid.
This utility model is achieved by the following technical solution:
A kind of drainage bag, comprise the drainage bag main body that stores drainage-fluid, drainage bag main body top is provided with drainage bag connection tube, and described drainage bag connection tube is connected with urinary catheter, it is characterized in that: described drainage bag connection tube is provided with check valve, only allow liquids and gases to flow in drainage bag main body; Drainage bag main body below is provided with discharge tube, and discharge tube lower end is provided with vent valves; Drainage bag main body top is also provided with air conduit, communicates with outside air, and air conduit is provided with air conduit valve, during the interior liquid of discharge drainage bag, opens air conduit valve and vent valves, and balance drainage bag main body inner and outer air pressure is poor, thereby accelerates mass rate of emission.
Be further characterized in that, flow speed controller is installed on discharge tube;
Be further characterized in that, drainage bag main body top is provided with and is linked with, and is printed on scale in main body.
The beneficial effects of the utility model are: this drainage bag is simple in structure, easy to operate, can under the prerequisite of safe handling, effectively improve fluid discharge speed, fully avoid backflowing, and can control drainage speed, adapt to the different user demands such as medical science sample examination or discharge drain.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is further described.
Fig. 1 is the schematic diagram of this utility model drainage bag.
In figure, 1 drainage bag main body, 2 drainage bag connection tubes, 3 check valves, 4 discharge tubes, 5 vent valves, 6 air conduits, 7 air conduit valves, 8 flow speed controllers, 9 are linked with.
The specific embodiment
Accompanying drawing has shown a kind of specific embodiment of the present utility model.This drainage bag comprises the drainage bag main body 1 that stores drainage-fluid, drainage bag main body 1 top is provided with drainage bag connection tube 2, described drainage bag connection tube 2 is connected with urinary catheter, it is characterized in that: described drainage bag connection tube 2 is provided with check valve 3, only allows liquids and gases to flow in drainage bag main body; Drainage bag main body 1 below is provided with discharge tube 4, and discharge tube 4 lower ends are provided with vent valves 5; Drainage bag main body 1 top is also provided with air conduit 6, communicate with outside air, air conduit 6 is provided with air conduit valve 7, opens air conduit valve 7 and vent valves 5 during the interior liquid of discharge drainage bag, balance drainage bag main body inner and outer air pressure is poor, thereby accelerates mass rate of emission.
Be further characterized in that, flow speed controller 8 is installed on discharge tube 4;
Be further characterized in that, drainage bag main body 1 top is provided with and is linked with 9, in main body 1, is printed on scale.
Above-mentioned example of the present utility model is only for this utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here cannot give all embodiments exhaustive.Every still row in protection domain of the present utility model of apparent variation that the technical solution of the utility model extends out or change that belong to.
