After urine sampling collection is finished, the upper structure including the flared portion  1 , the guide tube  2 , the guide tube fixation plug  3  including the vent  31  and ventilation tube  32  is removed, and the cap  400  is placed over the upper part of the urine collection tube  4 , thus securely and more permanently sealing the urine inside the urine collection tube  4  for future use. 
     The above allows for a urine sampling from the discharge member, in which flared portion  1  for containing the urine, urine collection tube  4  taken through guide tube fixation plug  3  is temporarily fixed fixing plug, into the urine through the guide tube  2  take urine collection tube  4 , the gas from the urine collection tube  4  is discharged through the exhaust hole  32  and the exhaust pipe  31 , to avoid contamination of medical patients. The above provides for a simple structure that is low in cost, safe and reliable. 
     In another embodiment, as shown by  FIGS. 7, 8, 11, and 12 , a self-discharge funnel urine samples, including a bell shaped mouth section  1  for holding urine, provided at the lower end of the bell cavity and the guide tube  2  and a flared portion provided in the guide tube communicating with bell shaped mouth section  1   2  into the outer wall of the insert taken for urinary catheters  4  and can take the urinary catheter fixing mechanism exhaust gas discharged from conduit  4  within three. The exhaust duct fixing mechanism and the lower part  3  is set to take the upper end of the outer wall of urinary catheters  4  matches catheter lock chamber  31 , the catheter lock chamber  31  near the side of the bell section  1  of the sealed end  311 , cavity  31  away from the catheter fixing bell shaped mouth section  1  an open end  312  side. Lumen catheter fixed in the sealed end  311  side  31  and catheter fixing cavity  31  communicates with the exhaust pipe  32 . 
     When receiving the urine, the bell shaped mouth section  1 , reduces splashing of urine, urine spill and avoids spilling on to the patient&#39;s hands. Urine collected into the bell portion of the cavity, builds up to the bottom of the bell section  1  through the lumen of the guide tube  2  and flows into the taking of urine catheter lumen  4 . 
     The fixed duct cavity  31  and the upper urinary catheter outer wall  4  matches that take four sets of urinary catheters set sealing contact with the inner wall of the cavity  31  of the fixed duct  31  of the catheter after taking lock chamber and the outer wall of the upper urinary catheter  4 . The effect is: sleeve set into the fixed lumen catheter  31  to take temporary urinary catheters  4  can be fixed to avoid falling; when taken into the urine within the urinary catheter  4 , take air through the urine guide tube  2  and take urinary catheter conduit  4  within 4 after discharge gap lumen catheter into the lock chamber  31  into the air lock chamber  31  within the catheter can be discharged through the exhaust pipe and pipe fixing cavity  31  in communication  32 ; when taken within four urinary catheters filled with urine, the guide take the tube  2  into the urine excess urinary catheters  4  can be discharged through the exhaust pipe  32 . 
       FIGS. 7-10 , the exhaust pipe  32   4  disposed in the cavity  31  of fixed duct seal the end of the end portion  311 . This pollution takes urinary catheter structure  4  which are appropriate, urine collection tube  4  of the sealing membrane  5  is provided with a fissure, crack sealing film  5  to the central depression of the bowl-like structure, provided with a plurality of recessed bottom crack. If the force is consistent with the direction of the recess, crack opening, the guide tube  2  can smoothly enter the urine collection tube  4  are taken. Reverse by a smaller force, shrink cracks, fissures closed so enhanced, taking the urine of gas or liquid within the conduit  4  does not flow out. But the force is large solids can smoothly access. 
     After, the means to take urine collection tube  4  into the catheter end portion  31  of the lock chamber, an outer wall and an inner wall  31  takes urinary urine collection tube  4  is fixed in sealing contact, but the fissure sealing film  5  of the bowl-shaped recess formed basin body structure space, space is on the basin body sealing end  311  of the end portion of the bowl to take up space communication urine collection tube  4  and an exhaust pipe  32 . 
     Referring to  FIGS. 9 and 10 , will take before using urine collection tube  4  through cracks fissure sealing film  5  is set into the outer wall of the guide tube  2  and take home four sets of urinary catheters and catheter fixing the insert into the cavity  31  within which to take the top edge of urine collection tube  4  holding the ends of the catheter lock chamber  31  sealed ends  311 . Then the bell section  1  is on the urethra urination, urine in the trumpet section  1   l  protect concentrated at the bottom into the guide tube  2 , and  2  through the guide tube into the lumen of the catheter within the urinary take  4 . At the same time, take the urine  4  pipe gas through fissures in the membrane seal the gap between  2  and  5  of the guide tube is discharged into the basin body space fissure sealing film  5 , and then with the bowl-shaped space communicating the exhaust pipe  32  is discharged. 
     When taken within four urine filled urinary catheters, urinary catheters to stop urinating remove take  4  complete urine sample. When the patient is not found in time, proceed to take urine urinary catheter  4 , the excess urine along the gas discharge passage by the exhaust pipe  32 , inside the bell section  1  avoid the accumulation of excessive urine overflow easily contaminated patients hand. 
     Referring to  FIGS. 11 and 12 , and as shown in  FIG. 7  the exhaust pipe  32  is disposed near the sealed end of the conduit  311  fixed to the end portion of the side wall  8  cavity  31 . At the same time, the cavity  31  of fixed duct lumen sealed end  311  side end of the stopper  313 , the stopper  313  is not lower than the limit point of the exhaust gas inlet pipe  32 . 
     If setting stopper  313 , take  4  urinary catheters inserted catheter lock chamber  31  easy to make too deep within the exhaust pipe  32  of the gas inlet pipe  4  is taken on the edge of the outer wall of the urinary blockage, would not achieve the effect of exhaust, leading to urinary failure. If we take  4  urinary catheters inserted catheter lock chamber  31  is too shallow, poor urinary catheter  4  is secured to take effect, easy prolapse;  31  and the inner wall of the outer wall  4  to take urinary catheters and catheter lock chamber is also prone to poor sealing contact effect occurs in urine was taken by urinary catheter slit  431  and the inner wall of the outer wall of the cavity between the catheter fixing leaking, leading to contamination of urine taken  4  outer urinary catheters, patient hands contaminated urine. 
     It is set so that the stopper  313  is fixed to take the urine catheter lumen catheter  31  to achieve the best depth, both to ensure the exhaust gas inlet pipe  32  will not be taken on the edge of the outer wall of the urinary catheter  4  jam. But also to ensure the fixed effects take urinary catheters  4 , it avoids taking urinary catheters  4  off. But also to ensure the take urinary catheters and catheter fixing the outer wall  4  wall sealing cavity  31 , to avoid contamination of urine taken urinary catheters  4  outer wall. 
     It need to be reminded that, when the end of the urine sample, taken at the upper urinary levels of  32  and an exhaust pipe conduit  4  fissure sealing film  5  may accumulate a small amount of urine. But with the guide pipe  2  taken from urinary catheters pulled within four, taking the urine will form a negative pressure within the catheter  4 , the above accumulated urine adsorption housed in urinary catheters  4  are taken. In the specific embodiment, the guide tube  2  into the substance of the volumetric capacity to take  4  urinary catheters should be greater than the volume of accumulated urine in order to avoid a small amount of urine leakage, to avoid contamination of patients. Meanwhile, in order to ensure the existence of a gap between the use of crack sealing film  2  and the guide tube  5 , fissure sealing film  5  should not be too small, and the outer diameter of the guide tube  2  should not be too large. If the urine is not set up to take fissure sealing inner catheter  4  film  5 , the utility model can also be used normally, but the end of the urine sample, taken unplug urine collection tube  4  and inspection process required to be very careful to avoid contamination of urine splashing operator hand. 
     The above provides a urine sample from the exhaust funnel, its bell unit  1  received for holding urine, take temporarily urinary catheter  431  fixed to the lower fixed bell  1  through the catheter lumen, the urine through the guide tube  2  take the urine into the urine collection tube  4 , take the gas in the urine collection tube  4  gas through the guide tube  2  and  4  take lumen catheter urinary void discharged into the vent  31  and ventilation tube  32  is discharged through the exhaust pipe. When there is too much urine, excess urine will overflow through the ventilation tube  32 , to avoid the risk of contamination of health care. 
     In yet another embodiment, as shown in  FIGS. 15-18 , a urine sampling bag includes a urine sampling funnel in the form of a urine sampling bag  1  for collecting urine, and urine collection tube  4  can be fixed at its upper portion to the lower portion of the sampling bag  1  at the guide tube in the form of a guide tube fixation member  2 . The catheter is fixed within a lumen of the guide tube  2  and the sampling bag  21  and the interior cavity I ventilation tube  22 . 
     Before urine collection, a urine collection tube  4  is tightly fixed and sealed to a guide tube in the form of a fixation member  2 . Both a guide tube  21  and a ventilation tube  22  are located in the inside of the fixation member  2  and the sealing member is fixedly connected to the fixed conduit, the urine guide tube of the catheter taken through the lumen of the urine collection tube  4  provided on the fixed body  221  and the discharge hole  22  and the sampling bag I are in communication. Sampling bags placed in front of the I urethra when the urine sample extraction, open the bag, the bag avoid physical contamination of urine splashing. Agglomeration into the urine in the sampling bag  1  at the bottom of the sampling bag through the guide tube  21  into the conduit  2  fixed urine collection tube  4  to take the urine catheter lumen; At the same time, taking urinary catheters gas in the urine collection tube  4  through the conduit  2  fixed body in the ventilation tube  22  is discharged, thereby completing the taking of urine. 
     To ensure the smooth extraction of urine, the length of the ventilation tube  22  located at the guide tube fixation member  2  of the sampling bag  1  is the same length as that of the guide tube  21 , so when the urine flows into the bottom of the bag, the inlet of the guide tube  21  is situated at a position lower than that of the inlet of the ventilation tube  22 , urine can first flow to the first inlet guide tube  21  into the urine collection tube  4 , preventing the clogging of the ventilation tube  22 , making gas discharge from the urine collection tube  4  poor. 
     In order to ensure that the gas inside the urine collection tube  4  is discharged freely, the length of the guide  21  on the side of the catheter away from the fixed sampling bag body than on the same side of the vent hole  22  long tube. urine collection tube  4  taken in the urinary catheters, the air located above the urine, an exhaust vent port portion  22  than the guide tube  21  higher, to facilitate the smooth discharge of air. When the urinary catheter takes the urine level rises urine collection tube  4  blocked the vent exhaust port  22 , the residual gas in the conduit urinary collection tube  4  to stop taking the urine discharged, taking the end of the urine.
