Abstract

The utility model discloses a novel drainage bag. The upper end of a bag body is connected with the liquid outlet end of a three-way valve, and the other liquid outlet end of the three-way valve is connected with a sampling bottle. A change-over switch for controlling the liquid flowing direction is arranged on the three-way valve. A liquid inlet tube is in threaded connection with the upper end of the three-way valve, a moving bolt is fixed at the upper end of the liquid inlet tube, a transparent sleeve is arranged outside the liquid inlet tube and the moving bolt, the outer wall of the transparent sleeve is provided with scales, and a spring is arranged between the lower end of the transparent sleeve and the moving bolt. A drainage tube matched with the liquid inlet tube in a plugged mode is arranged above the liquid inlet tube. The upper end of the transparent sleeve is fixedly connected with the drainage tube through a rubber sleeve. The novel drainage bag is simple in structure, quick and convenient to operate, low in cost, accurate in drainage liquid metering and convenient to sample and further has remarkable practicability.

Description

Novel drainage bag
Technical field
This utility model relates to a kind of medical supplies, relates in particular to a kind of novel drainage bag.
Background technology
Existing drainage bag mostly carrys out the amount of liquid in metering bag by the scale on bag wall, due to drainage bag adopt made of plastic, can there is distortion in various degree with the difference of amount of liquid, finally cause amount of liquid and the corresponding larger discrepancy of mark scale existence.Also have in addition and adopt the scheme of weight metering to occur, it is to be provided with the electronic components such as pulling force sensor and corresponding power supply, display screen in drainage bag upper end, although this means can realize the object of accurate measurement, but structure is comparatively complicated, cost is higher, be unfavorable for being applied in this class of drainage bag and disappear on medical supplies soon, therefore be not used more widely.In addition, in drain process, often need the sample liquid taking a morsel in order to checking, existing drainage bag does not possess the function that samples liquid midway, and after drainage completes, the liquid in drainage bag takes out and also has certain operation easier, in the time sampling liquid, easily trickle down to outside, pollute.
Utility model content
For overcoming prior art deficiency, it is a kind of accurately, with low cost to amount of liquid metering in bag that this utility model provides, and sampling liquid more for convenience, the novel drainage bag of handling safety health.
For realizing above-mentioned technical purpose, this utility model by the following technical solutions: a kind of novel drainage bag, comprise bag, it is characterized in that: a liquid outlet of described bag upper end connecting tee valve, another liquid outlet of three-way valve is connected with a sampling bottle; Described three-way valve is provided with the permutator of controlling flow direction; Described three-way valve upper end is provided with the feed tube being threaded, the upper end of described feed tube is fixed with a trip bolt, the outside of feed tube and trip bolt is provided with a transparent casing, and the outer wall of described transparent casing is provided with scale, between the lower end of transparent casing and trip bolt, is provided with spring; Described feed tube top is provided with the drainage tube coordinating with its grafting; The upper end of transparent casing is fixedly connected with drainage tube by a gum cover.
The utlity model has following beneficial effect: the weight-driven trip bolt that bag and internal liquid thereof produce overcomes spring force and moves down, scale outside transparent casing corresponding to trip bolt position can show the volume of liquid, due to the only weight impact of liquid body of trip bolt position, and irrelevant with the change of shape of bag, therefore it is comparatively accurate to the metering of amount of liquid; Three-way valve is provided with the permutator of controlling flow direction, in drain process, can conveniently obtain appropriate sample by sampling bottle, and without getting from drainage bag; Three-way valve is threaded with feed tube, in drain process, can change easily drainage bag, after drain simultaneously completes, can seal drainage bag by three-way valve.It is simple in structure, convenient to operation, with low cost, to draining fluids accurate measurement, and convenient sampling, and then there is significant practicality.
