Detailed Description

The present application is described in further detail below with reference to figures 1-5.

The embodiment of the application discloses drainage bottle 1 that can take a sample, including drainage bottle 1 itself, it is equipped with a sample connection 2 to run through on the upper end cover of drainage bottle 1 itself, can carry out the work of taking a sample when not influencing the normal drainage of drainage bottle 1, at a sample connection 2 detachable installation sampling device 3, sampling device 3 is including the link 4 and the sampling tube 5 of mutual intercommunication, link 4 is equipped with screw thread 8 on the lateral wall with 2 adaptation installations of sample connection, it passes through threaded 8 with sample connection 2, the clinical use demand of adaptation drainage bottle 1, need take a sample in real time to severe patient, can install sampling device 3 at sample connection 2, convenient sample, to some light disease patients, probably need not take a sample in real time or when not taking a sample, just can demolish sampling device 3, use as normal drainage bottle 1.

The connecting end 4 and the sampling tube 5 of the sampling device 3 are mutually communicated, in order to facilitate production, the sampling tube 5 and the connecting end 4 can be of an integrated forming or split inserting structure, one end of the connecting section end, which is far away from the sampling tube 5, is provided with an opening for inserting the sampler 10, the sampler 10 can adopt a device which is similar to an injector and can be drawn, and the drainage liquid in a drainage bottle is drawn through the sampler 10 to be taken as a sample.

Sampling tube 5 passes through the installation of link 4 and sample connection 2, and it is for the complete holding in drainage bottle 1 inside, and its one end of keeping away from link 4 extends to drainage bottle 1 bottom, no matter how much can both ensure sampler 10 and can sample in drainage bottle 1 interior hydrops, and its extraction is drainage bottle 1 bottom hydrops, does not influence drainage bottle 1's normal drainage work.

The utility model discloses preferred, the internal diameter of sampling tube 5 is 0.7mm-1.5mm, can adopt the internal diameter of sampling tube 5 of minimum specification, but the length of adaptation sampling tube 5 satisfies it and can reach drainage bottle 1 bottom, ensures simultaneously that sampler 10 carries out the extraction of hydrops in minimum extraction stroke.

In order to guarantee the airtight of drainage bottle 1, be equipped with a sealed lid 6 in sample connection 2 department, its sample connection 2 is in encapsulated situation all the time when not needing the sample, and is preferred, and the open-ended bore that sampling device 3's link 4 was seted up is unanimous with the bore size of sample connection 2, after guaranteeing sample connection 2 installation sampling device 3, its sealed lid 6 can the sealed sample opening of living of adaptation, further guarantees the leakproofness of drainage bottle 1, does not influence its normal work.

Be connected between sealed lid 6 and the sample connection 2 and be equipped with a splice bar 7, sample connection 2 upwards extends first-order mount table along the upper end cover of drainage bottle 1 itself, the one end of splice bar 7 is fixed on the mount table, the other end is fixed on sealed lid 6, adopt disjunctor structure between sealed lid 6 and the sample connection 2, guarantee to open the back, its sealed lid 6 can directly hang on sample connection 2, sealed lid 6 need not to be taken or place in addition, can avoid putting indiscriminately and lead to sealed lid 6 to lose, its sealed lid 6 can adopt push type structure or screw thread 8 connection structure and sample connection 2 or the sealed cooperation of opening, also can adopt current flip formula bottle lid.

In order to guarantee to open the back at sealed lid 6, prepare the in-process of sample, the air can not cause the pollution in entering into drainage bottle 1 from the sample opening, the utility model discloses it is preferred, be located to be equipped with a plurality of valves 9 on the one end passageway of being close to sampling tube 5 at link 4, a plurality of valves 9 evenly distributed are in the both sides of its passageway, and a plurality of valves 9 all set up along orientation sample liquid flow direction to make the passageway of link 4 be opening state along sample liquid flow direction, otherwise then be closing state, can play the effect of a one-way blocking circulation of air, guarantee the interior sterile condition of drainage bottle 1.

Valve 9 structural similarity is the artery valve structure, when the hydrops was extracted along sampling tube 5 and is got into the syringe, the valve 9 in 4 passageways of link 4 this moment is whole be present and is squeezed and open and be in the open mode by the extrusion, if when air is advanced in reverse by outside to drainage bottle 1, because valve 9 open orientation, the air will extrude valve 9 and make its both sides contradict each other, makes valve 9 opening be in the state of closing, is that the air can't get into in the drainage bottle 1.
