Background
The conventional urine tube has two types, one is closed type and comprises a test tube and a cover cap covering the mouth of the test tube, and the urine sample is stored in the test tube. In conducting the assay, the laboratory technician first needs to unscrew the cap, then uses a straw or other sampling device to aspirate the urine sample from the tube, and then injects it into the testing device for testing. The laboratory technician wears protective gloves when the operation, and the operation is very inconvenient when opening the block, still causes the urine sample to spill in case of losing one's hand to produce the pollution to surrounding environment and on-the-spot instrument.
Another type of urine tube is open, i.e., the urine tube is open, so that the odor of the urine sample can be emitted into the surrounding air to cause odor and pollution. Meanwhile, the long-term contact and volatilization of the urine sample with the air can cause the change of the concentration and the components of the urine sample, and the urine sample is also easily polluted, thereby influencing the test result.

Detailed Description
Example 1
As shown in fig. 1 to 3, a puncture type urinary catheter for facilitating sampling includes a test tube 1, a cap 2 covering a nozzle at the top of the test tube 1, and a septum 3 provided on the cap 2.
The cap 2 includes that threaded connection is at the outer nut 6 of the mouth of pipe of test tube 1 and stopper the intraoral stopper pipe 7 of the mouth of pipe of test tube 1, the top of nut 6 and the top fixed connection who fills up pipe 7, fill up pipe 7 and the sealed cooperation of test tube 1, diaphragm 3 is fixed to be set up in the bottom that fills up pipe 7. The plug tube 7 is in a conical cylinder shape, and the diameter of the upper end of the plug tube 7 is larger than that of the lower end of the plug tube 7.
Because the diaphragm 3 is arranged at the bottom end of the plug tube 7, the plug tube 7 extends into the test tube 1, thereby protecting the diaphragm 3 and preventing the diaphragm 3 from being broken due to accidental impact, and further causing the pollution caused by the overflow of the urine sample.
The material of nut 6 and stopper pipe 7 is HDPE (high density polyethylene), and when actual manufacturing, nut 6, stopper pipe 7 and sealing ring 5 formula as an organic whole adopt HDPE material injection moulding. The test tube 1 is injection molded by using high-transparency PP (polypropylene) or PS (polystyrene) material. The production process is simple, and is convenient for batch production and production cost reduction.
The diaphragm 3 is made of aluminum foil and is heated and then hot-pressed to the bottom of the plug tube 7, so that the diaphragm 3 and the plug tube 7 are bonded and sealed.
In use, the test person can puncture the septum 3 by holding a pipette or other sampling device, and then extend the tube 1 to take a urine sample for testing. In the process, the cap 2 does not need to be unscrewed, the operation is convenient and quick, the urine sample is not overflowed to cause pollution, and the testing efficiency is improved. Because the urine tube is closed, the urine can not volatilize into the air to generate peculiar smell, the concentration and the components of the urine sample can not be changed, and the urine sample can not be easily polluted by the surrounding environment.
Example 2
As shown in fig. 4 and 5, the present embodiment is different from embodiment 1 in that:
the section of the diaphragm 3 is corrugated, the shape of the diaphragm is similar to that of water waves, and the diaphragm 3 is distributed on the surface of the diaphragm in concentric circles.
Because the temperature of the urine sample during sampling and the environmental temperature during sampling are difficult to be consistent with the temperature during urine sample testing, the air in the urine tube can expand with heat and contract with cold, and the corrugated diaphragm 3 can well compensate the volume change of the air in the urine tube caused by expansion with heat and contraction with cold, and prevent the diaphragm 3 from being broken due to the pressure change generated by the expansion with heat and contraction with cold of the air in the urine tube.
Example 3
As shown in fig. 6, the present embodiment is different from embodiment 1 in that:
the diaphragm 3 is made of rubber, three notches 4 are formed in the middle of the diaphragm 3 at intervals of 120 degrees along the radial direction, and the three notches form a herringbone shape.
The three herringbone cuts can seal the test tube 1 and do not influence the suction tube and the sampling instrument to extract the urine sample from the test tube. When sampling, only a suction pipe or a sampling instrument is inserted from the incision 4, and the urine sample stored in the test tube 1 can be sucked out.
The above-mentioned embodiments are described in detail and specifically to show the preferred embodiments of the present invention, which are only used to illustrate the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the same, but not to limit the present invention, and the scope of the present invention should not be limited by the present embodiment, i.e. any equivalent changes or modifications made by the spirit of the present invention, for those skilled in the art, within the structure of the present invention, the local modifications inside the system and the changes, transformations, etc. between the subsystems are still within the scope of the present invention. At present, the technical scheme of the application has been subjected to pilot plant test, namely small-scale experiment before large-scale mass production of products; after the pilot test is finished, the investigation for the use of the user is carried out in a small range, and the investigation result shows that the satisfaction degree of the user is higher; the preparation of products for official production for industrialization, including intellectual property risk early warning research, has been set forth.
