Description

Technical Field

[0001] The utility model relates to the technical field related to medical devices, in particular to a midstream urine aseptic collection and retention device. Background Art

[0002] In modern medicine, testing plays an increasingly important role, and the accuracy of test reports plays a decisive role in the diagnosis and treatment of diseases. In clinical practice, urine culture requires the collection of midstream urine.

[0003] The existing collection and retention device has the following shortcomings when used: the delivery tube is directly inserted into the collection tube, and the midstream urine is subsequently collected through a set valve. However, the port of the collection tube is closed, and when urine enters the collection tube, the internal pressure increases, resulting in the subsequent urine being unable to enter smoothly. Utility Model Content

[0004] The purpose of the present utility model is to provide a midstream urine collection and retention device aseptically to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a mid-stream urine aseptic collection and retention device, comprising a conveying component, a collection tube connected to the conveying component, and a collection box, wherein the conveying component as a whole is composed of a first conduit, a second conduit, and a third conduit, a urine collector is provided at the upper end of the first conduit, a connector is provided at the lower end of the first conduit, the upper ends of the second conduit and the third conduit are both connected to the connector, the collection tube is connected to the lower end of the second conduit, the exhaust pipe provided at the upper end of the collection tube is connected to the third conduit through a fourth conduit, and the collection box is connected to the lower end of the third conduit.

[0006] Preferably, a two-position three-way valve is provided on the connecting head.

[0007] Preferably, the upper end of the collection tube is provided with a movable cover through a thread, a rubber plug is provided at the center of the movable cover, and the lower end of the second conduit and the lower end of the exhaust pipe are both passed through the rubber plug and placed inside the collection tube.

[0008] Preferably, the lower end of the second conduit is fixedly connected to the exhaust pipe via a connecting frame.

[0009] Preferably, a scale is provided on the wall of the collection tube.

[0010] Preferably, a one-way valve is installed in the middle of the fourth conduit.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. By setting an exhaust pipe at the upper end of the collection tube and connecting the lower end of the exhaust pipe to the interior of the collection tube, the air inside the collection tube is discharged through the exhaust pipe during sample collection, ensuring that the middle urine in the second catheter can smoothly enter the collection tube. At the same time, the exhaust pipe and the second catheter are connected through a connecting frame, which makes it convenient and quick to disconnect the second catheter, the exhaust pipe and the collection tube;

[0013] 2. By setting up a fourth conduit, the two ends of the fourth conduit are connected to the exhaust pipe and the third conduit respectively. During use, when the urine in the collection tube is full, the subsequent urine enters the collection box through the exhaust pipe, the fourth conduit, and the third conduit, without having to operate the two-position three-way valve again. At the same time, the one-way valve set on the fourth conduit can effectively prevent the previous urine from entering the collection tube through the third conduit, the fourth conduit, and the exhaust pipe.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-2 The utility model provides a technical solution: a mid-stream urine aseptic collection and retention device, comprising a conveying component and a collection tube 1 and a collection box 2 connected to the conveying component. The conveying component as a whole is composed of a first conduit 3, a second conduit 4 and a third conduit 5. The upper end of the first conduit 3 is provided with a urine collector 13, the lower end of the first conduit 3 is provided with a connector 6, the upper ends of the second conduit 4 and the third conduit 5 are both connected to the connector 6, the collection tube 1 is connected to the lower end of the second conduit 4, the exhaust pipe 7 provided at the upper end of the collection tube 1 is connected to the third conduit 5 through a fourth conduit 8, and the collection box 2 is connected to the lower end of the third conduit 5.

[0019] The connector 6 is provided with a two-position three-way valve 9 .

[0020] The upper end of the collection tube 1 is provided with a movable cover 10 through a thread, and a rubber plug is provided at the center of the movable cover 10. The lower end of the second conduit 4 and the lower end of the exhaust pipe 7 are both passed through the rubber plug and placed inside the collection tube 1.

[0021] The lower end of the second conduit 4 is fixedly connected to the exhaust pipe 7 via a connecting frame 11 .

[0022] The wall of the collection tube 1 is provided with scales.

[0023] A one-way valve 12 is installed in the middle of the fourth conduit 8 .

[0024] Specifically, when using the present invention, the collection tube 1 is connected to the second conduit 4 and the exhaust pipe 7. Initially, the two-position three-way valve 9 is adjusted to connect the first conduit 3 with the third conduit 5, and urine is collected through the urine collector 13. The urine enters the interior of the collection box 2 through the first conduit 3, the connector 6, and the third conduit 5. Subsequently, the two-position three-way valve 9 is adjusted to connect the first conduit 3 with the second conduit 4. At this time, midstream urine enters the interior of the collection tube 1 through the first conduit 3, the connector 6, and the second conduit 4, completing the collection of the midstream urine sample.

[0025] Since the exhaust pipe 7 is connected to the interior of the collection tube 1, it is ensured that urine enters the interior of the collection tube 1. When the collection tube 1 is full of urine, the subsequent urine enters the interior of the collection box 2 through the exhaust pipe 7 and the fourth conduit 8. Finally, the collection tube 1 is separated from the second conduit 4 and the exhaust pipe 7.
