Specific embodiment

Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.

A kind of specimen collecting device of urinary system operation, including mesh grid cartridge filter 1 and pluggable mesh grid cartridge filter 1 Interior mesh grid extends cylinder 2, and it is unlimited setting which, which extends 2 both ends of cylinder, and is provided in mesh grid cartridge filter 1 Disposable filtering mesh bag 5 of the housing on mesh grid extension cylinder 2, wherein mesh grid extension 2 height of cylinder is lower than mesh grid cartridge filter 1 Highly, and 5 height of filtering mesh bag is greater than 1 height of mesh grid cartridge filter, then specimen collecting device is placed on use in operation In accepting the undertaking bucket entrance for excreting physiological saline in operation, the conduit outlet end for being used to export physiological saline is inserted into In specimen collecting device, that is, in insertion mesh grid extension cylinder 2 and it is extended to the over bottom in Filter-screen bag 5, then operation export Physiological saline enter in filtering mesh bag 5 and be filtered, wherein solid siltation bottom in filtering mesh bag 5, and liquid then leads to The aperture in the aperture and mesh grid cartridge filter 1 of crossing filtering mesh bag 5 drops in the undertaking bucket for accepting physiological saline.

It is respectively welded outwardly extending mounting ear 3 at 1 top both ends of mesh grid cartridge filter simultaneously, wherein mounting ear 3 can It is locked on the edge for accepting bucket feed inlet by bolt to reinforce its stability, and mesh grid cartridge filter in above process 1 can play support fixed function to filtering mesh bag 5 and mesh grid extension cylinder 2, prevent filtering mesh bag 5 and mesh grid from extending cylinder 2 It falls into accepting in bucket, and in order to enable 5 spread apart of filtering mesh bag, 2 have also been arranged radially in 1 bottom of mesh grid cartridge filter~ 4 groups arranged in a crossed manner and strut bar 7 for strut 5 bottom of filtering mesh bag, and multiple groups strut between 7 bottom end of bar in same level Face wherein strutting bar 7 in the door type structure of back-off setting, and struts 7 both ends of bar bottom corresponding with mesh grid cartridge filter 1 respectively Portion's sidewall weld, this also allows for 5 upper half of filtering mesh bag and is strutted by mesh grid extension cylinder 2, and its bottom is then by strutting bar 7 It struts, to prevent filtering mesh bag 5 from shrinking together, while filtering mesh bag 5 is strutted and is tightly attached to it by mesh grid extension cylinder 2 On the inner sidewall of mesh grid cartridge filter 1, and strutting 7 bottom end of bar will then strut filtering braiding 5 bottom end of mesh bag and be pressed on braiding In net filtration cylinder 1 on bottom.

And in order to reinforce stability of the filtering mesh bag 5 on mesh grid extension cylinder 2, mesh grid extends cylinder in the present embodiment The 2 lateral wall upper halves, which are recessed inwardly, a circle limiting slot 4, and outer be cased with is fixed in limiting slot 4 on filtering mesh bag 5 Retaining mechanism 6, wherein retaining mechanism 6 is rubber band and covers on the filtering mesh bag 5 in limiting slot 4.

The application method of the present embodiment: mesh grid cartridge filter 1 is inserted into the undertaking bucket feed inlet for accepting physiological saline, Middle mounting ear 3 can be locked on the edge for accepting bucket feed inlet to reinforce its stability, then by 5 sets of filtering mesh bag by bolt On mesh grid extension cylinder 2,5 upper half of filtering mesh bag extends cylinder 5 by mesh grid and struts at this time, and its bottom is then by strutting bar 7 strut, to prevent filtering mesh bag 5 from shrinking together, then by the housing rubber band on filtering mesh bag 5, pass through rubber band Elastic force by 5 bundled fixed of filtering mesh bag mesh grid extension cylinder 2 on, wherein rubber band be stuck in limiting slot 4 can prevent its It is slided on filtering mesh bag 5, while filtering mesh bag 5 is strutted and is tightly attached to it in mesh grid cartridge filter 1 by mesh grid extension cylinder 2 On side wall, then the conduit outlet end for being used to export physiological saline insertion mesh grid is extended in cylinder 2 and is extended to the over Filter-screen bag 5 Interior bottom, then derived physiological saline of performing the operation is entered in filtering mesh bag 5 and is filtered, wherein solid siltation is in filtering mesh bag Bottom in 5, and liquid then passes through the aperture of filtering mesh bag 5 and the aperture of mesh grid cartridge filter 1 and drops to for accepting physiology salt In the undertaking bucket of water, as shown in Figure 1, the upper end of filtering mesh bag 5 and mesh grid extension cylinder 2 is pinched by finger after the completion of operation It is extracted out out of mesh grid cartridge filter 1, can also be expanded filtering mesh bag 5 and braiding by lifting the top of filtering mesh bag 5 certainly Exhibition cylinder 2 is extracted out out of mesh grid cartridge filter 1, is then removed rubber band and is simultaneously taken out mesh grid extension cylinder 2 out of filtering mesh bag 5 Out, then the resulting articles in disposable filtering mesh bag 5 are sample object at this time.

It describes the invention in detail, but content is only the preferred embodiment of the present invention, cannot be recognized above For for limiting practical range of the invention.Any changes and modifications in accordance with the scope of the present application should all still return Belong within patent covering scope of the invention.
