The purpose of this utility model provides a kind of improved drainage bag, and it can overcome pouring in down a chimney of discharged liquid effectively and prevent that antibacterial from stretching.

The purpose of this utility model is achieved in that a kind of drainage bag, comprising: a drainage bag bag; One drainage tube that is arranged in bag top bag mouth and communicates with bag; The one fixing fixing glued membrane of drainage tube of drainage tube; Its characteristics are that described drainage bag bag adopts the vest shape of being convenient to hang; Also comprise: also be provided with one and prevent the reverse fluid stopping device that discharged liquid is poured in down a chimney in described drainage bag bag, described reverse fluid stopping device one end is communicated with drainage tube, and its other end communicates with bag.

In drainage bag of the present utility model, described reverse fluid stopping device is a sleeve formula film shape, it be positioned at bag bag mouth upper end centre and with drainage tube and drainage tube thereof fixedly glued membrane be enclosed in wherein, the bag mouth of its thin film outer surface of upper and bag is tightly connected.

This utility model both had been convenient to hang because the bag shape is adopted the vest shape, the bag capacity is multiplied and bag on flow scale easily reach accurate situation; Simultaneously because the reverse fluid stopping device of a shape such as sleeve formula is set in the bag mouth on bag top, it is enclosed in drainage tube on the top of its sleeve, and the lower end of sleeve is in closure state when no discharge opeing is dirty, thereby has prevented pouring in down a chimney of waste liquid and stretching of antibacterial; Because the drainage bag bag adopts the low-pressure polyethylene plastics of 0.03 millimeter thickness and makes through blow molding process, not only there is not pin hole in thin film and has stopped seepage, and does not discharge toxic gas, has saved raw material greatly because of reduced thickness again in addition.

Describe details and working condition thereof in detail below in conjunction with accompanying drawing, other purpose and advantage therefrom also of the present utility model as can be seen according to the concrete device of the preferred embodiment that the utility model proposes.

Fig. 1 is the structural representation according to the drainage bag that the utility model proposes.

Referring to accompanying drawing, wherein Fig. 1 has indicated the drainage bag bag, this bag 1 has adopted the vest shape, so not only can be convenient to be suspended on a side of bed, and bag 1 its capacity of vest shape can be multiplied, and its shape becomes orthogonal three-dimensional shape when liquid flows into this bag 1, makes the flow scale 11 on the bag 1 reach comparatively accurate state easily.Described drainage bag bag 1 usefulness low-pressure polyethylene plastics are made through blow molding process, and the thickness range of bag 1 is that the thickness range of low-pressure polyethylene plastic sheeting is between 0.02 millimeter to 0.04 millimeter.Be provided with a bag mouth 2 on bag 1 top, be inserted with a drainage tube 3 in bag mouth 2, take over 31 in the fixedly connected drain of the other end of drainage tube 3, this drain is taken over 31 and can be connected with the pipe of patient's discharge opeing drain on one's body.Be arranged at drainage tube 3 and be surrounded by one deck on drainage tube 3 tube walls of bag mouth 2 in order to the fixing glued membrane 4 of the drainage tube of fixing drainage tube 3.Also be provided with one and prevent the reverse fluid stopping device 5 that discharged liquid is poured in down a chimney in described drainage bag bag 1, the one end is communicated with drainage tube, and its other end communicates with bag.But reverse fluid stopping device 5 various ways, oppositely fluid stopping device 5 is a sleeve formula film shape in this utility model.It is positioned at bag 1 bag mouth 2 central authorities, the outer surface of upper of its sleeve formula thin film and the bag mouth 2 of bag 1 are tightly connected, and drainage tube 3 is positioned at the top sleeve of sleeve formula thin film, the bottom of sleeve formula thin film with top with the bag mouth sealing and fixedly connected and hang from above in bag 1.Any position is provided with a porus excretorius 6 on bag 1, and this porus excretorius 6 is arranged on the top of bag 1 in this utility model, covers one deck sealed Cellophane 7 on this porus excretorius 6.

This utility model drainage bag is to make like this, with blow molding process the low-pressure polyethylene plastics are made the bag 1 of vest shape earlier, put into the reverse fluid stopping device 5 of sleeve formula thin film then in bag mouth 2 upper end centre, and 1 heat-sealing of sleeve formula thin film outer surface of upper and bag is connected, and bag mouth is also sealed thereupon.Again drainage tube 3 is inserted the sleeve that is positioned at reverse fluid stopping device 5 sleeve formula thin film tops, bag 1 upper end, and be that abrasive paper links together drainage tube 3 and bag 1 with fixing glued membrane 4, drain on drainage tube 3 other ends is taken over 31 be connected with the pipe of patient's discharge opeing drain on one's body, the intravital waste liquid of patient just can be in drainage tube 3 inflow drainage bag bags 1.Because being tightly connected with top and bag mouth, the bottom of reverse fluid stopping device 5 sleeve formula thin film hangs from above in bag 1, the lower end of sleeve is in closure state when no waste liquid is dirty, therefore the waste liquid in the bag 1 can reversely not pour in down a chimney or flow out outside the bag under the obstruction of the sleeve lower end of reverse fluid stopping device 5 closures, thereby prevented stretching and air pollution of antibacterial, helped patient to get well.When waste liquid is filled with bag 1, the sealed Cellophane 7 at porus excretorius 6 places on the bag 1 is opened, just can easily the waste liquid in the bag 1 be discharged outside the bag 1.
