Abstract

The utility model discloses a drainage bag which can measure accurately. The drainage bag comprises a drainage tube, a bag body and a switch, wherein, a scale mark is arranged on the bag body. The drainage bag is characterized in that: (1) a small fractional pack which is matched with the bag body and is provided with the scale mark is arranged in the bag body; (2) the corners of the bag body are of circular arc shapes. The drainage bag is an improvement based on the prior applied drainage bag, not only facilitates the accurate measurement drainage, but also can observe the drainage amount in the unit time, thereby being accurate and objective, facilitating the observation, enabling to develop the strong points and avoid the weak ones, and being more practical in clinic.

Description

The drainage bag of energy accurate measurement

Technical field

This utility model relates to the drainage bag technical field, is specifically related to the drainage bag of a kind of energy accurate measurement.

Background technology

The existing general measurement error that exists partially of drainage bag that uses clinically at present, its reason are that the drainage bag of closed can be because atmospheric pressure, along with drawing of drain night produces negative pressure and cause the drainage bag distortion, make that liquid level is irregular and can't accurately measure; Be exactly that some critical patients need tight monitoring unit interval output in addition, a sack drain of traditional drainage bag just can not reach the purpose of accurate metering of unit interval.And four square edges that present drainage bag is taked, after pouring out liquid, all can there be residual liquid in four corners at every turn, and the radix that causes measure next time is forbidden and can't accurately be measured.Moreover now present drainage bag all is 1000ML Fixed Design, and fixed big drainage bag baseline then is 100ML, just more can't accurate counting when failing to reach graduation mark under the smaller situation of draining fluids amount.

The utility model content

Technical problem to be solved in the utility model is the drainage bag how accurate measurement of a kind of energy is provided, and this drainage bag can address the above problem, and simple and reasonable, and production cost is low, suitable for mass production.

The technical problem that this utility model proposed is to solve like this: the drainage bag that the accurate measurement of a kind of energy is provided, comprise drainage tube, bag and switch, wherein bag is provided with graduation mark, it is characterized in that: be provided with the little branch pack of the work of being mated in the 1. described bag, this little branch pack is provided with metering scale; 2. the corner of described bag is set to circular arc.

Drainage bag according to energy provided by the utility model accurate measurement is characterized in that, described little branch pack is arranged on the lower end of described bag, is connected as a single entity with described bag, and described switch is provided with the lower end of little branch pack.

Drainage bag according to energy provided by the utility model accurate measurement is characterized in that, described little branch pack is arranged on the inside of described bag, this little branch pack upper end open, bottom sealing, the back side are being paid on the big drainage bag one side inner face, and the upper end is by pipeline and described drainage tube UNICOM.

Drainage bag according to energy provided by the utility model accurate measurement is characterized in that the top of described bag is provided with vent openings, in this opening piston is installed.

Drainage bag according to energy provided by the utility model accurate measurement is characterized in that the top of described bag is provided with lanyard or movable multi-functional hook.

Drainage bag according to energy provided by the utility model accurate measurement, it is characterized in that, described piston comprises interior valve, piston opening and last valve, and described interior valve can move up and down control piston and close, and described upward valve is provided with the gap can make piston communicate with atmosphere.

Drainage bag that can accurate measurement provided by the utility model is to improve on the basis of using drainage bag at present, has both solved to make things convenient for the accurately problem of metering of drain, can observe the problem of drainage flow again in the unit interval, accurately objective, the convenient observation maximized favourable factors and minimized unfavourable ones it, and be clinical more practical.

Fig. 2 is the structure chart of second kind of embodiment of drainage bag that can accurate measurement provided by the utility model;

Fig. 3 is the used structure of piston sketch map of this utility model.

Wherein, 1, drainage tube, 2, replace, 3, switch, 4, the pack of little branch, 5, piston, 501, the piston opening, 502, go up valve, 503, interior valve.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is further described.

The drainage bag of this energy accurate measurement, drainage tube 1, bag 2 and switch 3, bag 1 is provided with graduation mark, and be provided with the little branch pack 4 of the work of being mated, and little branch pack 4 is provided with metering scale, and the corner of bag 2 is set to circular arc, (first embodiment of the present utility model) as shown in Figure 1, little branch pack 4 is arranged on the lower end of 1 bag 2, is connected as a single entity with bag 2, and switch 3 is provided with the lower end of little branch pack 4.(second embodiment of the present utility model) as shown in Figure 2, little branch pack 4 is arranged on the inside of bag 4, and little branch packs 4 upper end open, the bottom sealing, the upper end is by pipeline and drainage tube 1 UNICOM,

The top of bag 2 is provided with vent openings, piston 5 is installed in this opening, piston 5 comprises interior valve 503, piston opening 501 and last valve 502, and interior valve 503 can move up and down control piston and close, and valve is provided with the gap piston is communicated with atmosphere on 502.

This utility model is exactly with four jiaos of obtuse angles that are modified into radian of original drainage bag, add a piston that is communicated with atmosphere again in the upper end, a straight tube, an obtuse angle drainage bag, pouch, lower end one tapping switch are protruded in lower end one, another kind then is on this basis, in big drainage bag, add a little branch pack, when the drain liquid stream is gone in the drainage bag, even under the few situation of drain liquid measure, in the pouch below liquid runs down arc obtuse angle flows into, also can accurately measure amount of liquid.Piston switch communicates with atmosphere, flow of liquid is fashionable can not to change the drainage bag shape because of atmospheric pressure makes drainage bag produce negative pressure, simultaneously because be piston switch, thereby can only air admission and do not allow liquid leakage in the drainage bag with regard to restriction, it is exactly drainage bag built-in one little branch pack, when coming out, the liquid drain at first enters in the little branch pack, under the few situation of drainage flow, can be by observing the scale above the little branch pack, calculate the drainage flow in the unit interval, when need zero clearing liquid counts again when hydroful in the pack of little branch or after the unit interval, only need big drainage bag and little branch pack one are squeezed, upset pours out that liquid get final product in the pack of little branch gently, and is convenient and swift, is difficult for pollution.

This utility model also can be made various mounting means, more than by the specific embodiment by the accompanying drawing illustrated embodiment, be to further describing that foregoing of the present utility model is made, but this should be interpreted as that the scope of the theme that this utility model is above-mentioned only limits to described example.Do not breaking away under the above-mentioned technological thought situation of this utility model, various replacements and change according to ordinary skill knowledge and customary means are made all should be included in the scope of the present utility model.
