Detailed Description
As shown in FIGS. 1-4, a sealed urine culture device needs to be sterilized with ethylene oxide and then used for a valid period. Comprises a urinary catheter 1, a raw urine receiving mechanism 2 and a middle urine receiving mechanism 3. The ureter 1 comprises a ureter main body 1-1, the front end of the ureter main body 1-1 is closed, liquid inlets 1-2 are formed in two side walls of the ureter main body 1-1, a first pipe orifice 1-3 and a second pipe orifice 1-4 are respectively arranged at the rear portion of the ureter main body 1-1, and the first pipe orifice 1-3 and the second pipe orifice 1-4 are respectively in transition fit connection with a raw urine receiving mechanism 2 and a middle urine receiving mechanism 3. Because the ureter 1 needs to be inserted into the urethral orifice to extract urine, the end is set to be a smooth closed end, and a larger opening is arranged on the side wall, so that liquid can be conveniently fed, and discomfort caused when the end is inserted can be avoided. The first pipe orifice 1-3 and the second pipe orifice 1-4 are conveniently and rapidly connected with the original urine receiving mechanism 2 and the middle urine receiving mechanism 3, so that the urine can be taken out in a detachable mode.
The original urine receiving mechanism 2 and the middle urine receiving mechanism 3 are identical in structure and comprise injector syringes 4, the internal capacity of the injector syringes 4 is larger than the maximum urine volume, and redundant space is guaranteed to be reserved. A hollow piston push rod 5 is arranged in the syringe needle cylinder 4, a hollow piston 6 is arranged at the front end of the hollow piston push rod 5, and the hollow piston 6 is made of rubber. The central push rod 7 penetrates through the hollow piston push rod 5 and the hollow piston 6 and then is integrated with a piston press plate 8 with a hole. The central push rod 7 is arranged in the central hole of the hollow piston push rod 5, the section diameter of the central push rod 7 is equal to the diameter of the central hole of the hollow piston push rod 5, and the length of the central push rod 7 is three-half of the length of the hollow piston push rod 3. The piston presser plate 8 and the hollow piston 6 are made of the same material and have the same diameter and are closely attached to the side wall of the syringe cylinder 4. When the piston pressing plate 8 is attached to the hollow piston 6, the hole on the piston pressing plate 8 is abutted against the end face of the hollow piston 6; when the piston pressing plate 8 is pushed to the bottom end of the syringe needle cylinder 4, the hole on the piston pressing plate 8 is abutted against the inner end face of the syringe needle cylinder 4.
The working principle and the process are as follows:
1) and sterilizing by a conventional method.
2) And slowly inserting the urinary catheter 1 into the urethral orifice by applying the aseptic operation principle.
3) The hollow piston push rod 5 in the urine receiving mechanism 3 is pushed to the bottom end of the syringe needle cylinder 4, and thus, the central push rod 7 is also pushed to the bottom end of the syringe needle cylinder 4. This state is shown in fig. 5, at this time, the middle urine receiving mechanism 3 is in a blocking state, and urine cannot enter; the central plunger 7 in the raw urine collecting means 2 is pulled out a distance, so that the hollow plunger 5 is also pulled out a distance. This state is shown in fig. 6, in which the urine receiving mechanism 2 vacates a part of the space and the inner space is in a negative pressure state. The fore-stream urine is discharged and collected in the raw urine receiving mechanism 2.
4) The central push rod 7 in the original urine receiving mechanism 2 is pushed towards the bottom end of the syringe needle cylinder 4, and due to the through holes distributed on the piston pressing plate 8, most urine overflows into the space between the piston pressing plate 8 and the hollow piston 6, and only a small amount of urine is pushed out of the urine tube 1. When the central push rod 7 reaches the bottom end of the injector needle cylinder 4, the piston pressing plate 8 is pressed against the bottom surface of the injector needle cylinder 4 to form a plug, and urine cannot enter or exit the original urine receiving mechanism 2. This state is shown in fig. 7-8.
5) The central plunger 7 in the urine collecting device 3 is pulled out a distance, so that the hollow plunger rod 5 is also pulled out a distance. This state is shown in fig. 6, in which the middle urine receiving mechanism 3 partially empties into the space and the internal space is in a negative pressure state, and midstream urine is discharged and collected in the middle urine receiving mechanism 3.
6) The central push rod 7 in the middle urine receiving mechanism 3 is pushed to the bottom end of the syringe needle cylinder 4, and due to the through holes distributed on the piston pressing plate 8, most of urine overflows into the space between the piston pressing plate 8 and the hollow piston 6, and only a small amount of urine is pushed out of the urine tube 1. When the central push rod 7 reaches the bottom end of the injector needle cylinder 4, the piston pressing plate 8 is pressed against the bottom surface of the injector needle cylinder 4 to form a plug, and urine cannot enter or exit the urine receiving mechanism 3. This state is shown in fig. 7-8. Because the common syringe needle cylinder 4 is provided with the scales, the urine volume can meet the collection requirement.
7) After the operation is finished, the middle urine receiving mechanism 3 is unscrewed from the urinary catheter 1 and then can be directly sent for examination. And other parts can be directly processed according to the hospital feeling requirement.
