Technical Field
[0001] The utility model relates to the field of urine catheterization sampling for nephrology, in particular to a urine catheterization sampling device for nephrology. Background Art
[0002] In the clinical treatment of renal diseases, catheterization is often used to drain the urine of patients. The principle is to insert a catheter into the patient's bladder and lead the urine into a urine storage bag through the catheter. During the treatment process, when we sample the patient's urine, we need to remove the catheter from the catheter bag and then insert the catheter into the sampling cup for sampling. This sampling method has the following defects: first, the urine flowing out of the catheter is easy to spill; second, the operation is cumbersome and requires repeated plugging and unplugging of the connecting tube. In view of this, we provide a nephrology catheterization sampling device for quick and hygienic catheterization sampling.
[0003] In order to solve the above problems, we propose a urinary catheterization sampling device for nephrology, which improves the deficiencies of the existing technology. Utility Model Content

[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. Example
[0021] like Figure 1-5 As shown, a urinary catheter sampling device for renal internal medicine comprises a urinary catheter 1 and a urine storage bag 2. The end of the urinary catheter 1 is connected to the urine storage bag 2 through a sampling mechanism. The sampling mechanism comprises a urine-passing tube 3, a side tube 4, a sealing block 5, a urine outlet tube 7, a limiting rod 8 and a reset spring 9. One side of the urine-passing tube 3 is sealed and connected to the side tube 4. A sealing block 5 is arranged in the side tube 4. A through hole 6 of an L-shaped structure is opened in the sealing block 5. The urine outlet tube 7 is also arranged on the sealing block 5. Two limiting rods 8 that can be pulled laterally are inserted into the side wall of the side tube 4, and a reset spring 9 is sleeved on the limiting rod 8. The upper end of the through hole 6 penetrates to the upper surface of the sealing block 5, and the lower end of the through hole 6 penetrates to the side surface of the sealing block 5. The urine outlet tube 7 is sealed and connected to the lower end of the through hole 6. The outer end of the urine outlet tube 7 extends to the outside of the side tube 4. The urine outlet tube 7 can be pulled on the side tube 4, and the upper and lower ends of the reset spring 9 are respectively fixed to the inner walls of the sealing block 5 and the side tube 4. The upper and lower ends of the urine tube 3 are respectively connected with an upper connecting pipe 10 and a lower connecting pipe 12. The upper connecting pipe 10 is provided with a connecting female head 11. The urinary catheter 1 is sealed and plugged into the connecting female head 11, and the lower connecting pipe 12 is sealed and plugged into the connecting female head of the urine storage bag 2. Two directly opposite plates 13 are also fixed on the urine outlet tube 7. The width of the sealing block 5 is greater than the internal width of the urine tube 3 and smaller than the internal width of the side tube 4. The structure of the urine catheter sampling device for nephrology is formed as a whole. The operation is simple and hygienic during sampling, and there is no urine spillage. There is no need to repeatedly plug and play the connecting pipe. It is extremely convenient to use and can meet the needs of patients with renal diseases to frequently take urine samples during catheterization.
[0022] The principle and advantages of the utility model are as follows: the upper end of the urinary catheter 1 is inserted into the bladder of a patient with a renal disease, and the urinary catheter 1 is used to drain the urine in the patient's body into the urine storage bag 2. When it is necessary to sample the derived urine, the tube mouth of the sampling tube is first sleeved on the outer port of the urine outlet tube 7, and then the thumb is attached to the side of the urine tube tube 3 away from the side tube tube 4, and the index finger and middle finger are clamped on both sides of the urine outlet tube 7, and then the index finger, middle finger and thumb are used to pinch the sampling mechanism together. At this time, Figure 5 As shown, the urine outlet tube 7 presses the sealing block 5 inwardly and pushes the sealing block 5 into the urine tube 3, blocking the urine tube 3 and preventing urine from flowing down through the urine tube 3. The reset spring 9 is stretched, and the urine in the urinary catheter 1 can be directly discharged into the sampling cup through the through hole 6 and the urine outlet tube 7. After the sampling is completed, the three fingers are released and the sealing block 5 is pulled back to its original position by the tension of the reset spring 9. Figure 2As shown, the urinary catheter tube 3 is opened, and the urine in the urinary catheter 1 flows into the urine storage bag 2, and finally the sampling cup is taken away. The sampling operation is simple and hygienic, there will be no urine spilling, and there is no need to repeatedly plug and unplug the connecting tube. It is extremely convenient to use and can meet the needs of patients with renal diseases to frequently take urine samples during catheterization, thereby improving practicality.
