After the urine is taken out, the urine can be inverted into a urinal or toilet from the urine collection bag opening 12, and then the cover 3 and the inner bag 2, that is, the connecting component of the two, can be placed in a medical waste storage tube.
[0019] A stirring mechanism is provided on the top of the inner bag 2 and the cover 3, and a preservative adding mechanism is provided on the lower right side of the inner bag 2. The preservative adding mechanism is used to add preservatives to the urine stored in the inner bag 2, and the stirring mechanism is used to stir the preservatives and urine;
[0020] A liquid level monitoring mechanism is provided on the sleeve 1 , and the liquid level monitoring mechanism is used to monitor the amount of urine in the inner bag 2 in real time.
[0021] See also Figure 1 , Figure 2 and Figure 3 The stirring mechanism includes a rotating rod 4 slidably inserted in the top center of the inner bag 2 and the center of the cover 3. A limiting ring 5 is integrally arranged on the rotating rod 4 and close to the inner top of the inner bag 2 and the top of the cover 3. The limiting ring 5 slides in contact with the inner top of the inner bag 2 and the top of the cover 3. The rotating rod 4 and the limiting ring 5 are made of medical grade PVC. Under such a setting, the rotating rod 4 can be limited from moving up and down on the cover 3. A stirring blade 6 is evenly and integrally arranged in an annular direction at the bottom of the rotating rod 4.
[0022] When the preservative is injected into the inner bag 2, the stirring blade 6 is rotated in the inner bag 2 by rotating the rotary rod 4, so that the urine and the preservative are evenly mixed, thereby achieving effective mixing of the urine and the preservative.
[0023] See also Figure 1 and Figure 2 The preservative adding mechanism includes a connecting piece 7 integrally arranged on the right side of the lower part of the inner bag 2, an opening is opened on one side of the lower part of the sleeve 1 and the connecting piece 7 passes through the opening, a squeezing bag 8 is integrally arranged on the right side of the connecting piece 7, and urine preservative liquid is quantitatively stored in the squeezing bag 8, and a discharge pipe 9 is integrally arranged at the bottom of the squeezing bag 8, the lower end of the discharge pipe 9 is interference-connected with the liquid inlet end of the one-way valve 10, and the discharge end of the one-way valve 10 is interference-connected with the discharge pipe 2 11, and the discharge pipe 2 11 is integrally connected with the inner bag 2.
[0024] After the patient collects urine for the first time, the squeezing bag 8 can be squeezed so that the urine preservative in the squeezing bag 8 is discharged into the inner bag 2 through the discharge pipe 1 9 and the discharge pipe 2 11. The one-way valve 10 can prevent urine from entering the squeezing belt 8.
[0025] See also Figure 3 and Figure 4The liquid level monitoring mechanism includes a fixed strip 13 embedded in the front and rear parts of the right side of the sleeve 1, wherein an infrared receiver 14 is evenly embedded vertically on one of the fixed strips 13, and an infrared light emitting head is evenly embedded vertically on the other fixed strip 13, and the infrared receivers 14 and the infrared light emitting heads correspond to each other one by one, and are arranged on the fixed strip 13 with a spacing of 0.2 mm;
[0026] The liquid level monitoring mechanism also includes an installation box arranged at the front of the sleeve 1, an industrial computer 16 arranged at the front of the installation box, and a development board arranged in the installation box. A processing module is arranged on the development board. The processing module is used to receive the response signal of each infrared receiver 14 in real time, and obtain the urine level of the inner bag 2 according to the analog mark analysis of each infrared receiver 14, and then calculate the urine volume.
[0027] The processing module includes a diversity access module, which is used to receive the response signals of each infrared receiver 14 in real time; the diversity access module is connected to the analog mark corresponding module, which is used to demarcate the received signal and the unreceived signal in the response signal according to the mark, and simulate it in the mark model in real time, obtain the closest received signal and unreceived signal boundary in the mark model through simulation, and obtain the liquid level according to the ordinate height corresponding to the boundary demarcation area; the analog mark corresponding module is connected to the gross removal module, which is used to calculate the urine volume based on the liquid level obtained by the analog mark corresponding module and the cross-sectional area of the inner bag 2, and then calculate the actual volume of urine based on the volume occupied by the stirring mechanism under different urine liquid level conditions.

[0028] Among them, the marking model is based on the distribution position of the infrared receiver 14 and the infrared light transmitting head and the corresponding height value setting. When the urine is higher than the infrared receiver 14 and the infrared light transmitting head at a certain level, the infrared receiver 14 cannot receive the infrared light emitted by the infrared light transmitting head due to the liquid barrier. At this time, the infrared receiver 14 at this level sends a signal of non-receiving signal to the diversity access module, and the analog marking corresponding module establishes the signal in the marking model in real time, and obtains the position corresponding to the signal of the nearest non-receiving signal and the signal of the receiving signal from the marking model in real time, and directly obtains the height value corresponding to the position. At this time, the height value is used to measure the urine level;
[0029] The gross volume removal module is used to calculate the initial volume b of urine by multiplying the measured liquid level by the cross-sectional area of the inner bag 2. The volume of the inner bag 2 occupied by the rotating rod 4 and the stirring blade 6 at different urine liquid level heights is known, and the gross volume removal module stores the volume r occupied by the rotating rod 4 and the stirring blade 6 corresponding to each liquid level, which is the gross volume information. At any liquid level height, the corresponding volume is r. n Therefore, in the calculation process, the obtained liquid level information is matched with the liquid level in the stored gross volume information, and the corresponding volume f occupied by the rotating rod 4 and the stirring piece 6 is obtained, and finally the urine volume t=br is calculated. n .
[0030] With the help of the printing processing module, the industrial computer 16 displays the urine level height and the confirmed urine volume in real time, which is convenient for nursing staff to count.
[0031] When in use, the inner bag 2 is placed in the sleeve 1, and the patient urinates into the inner bag 2 from the urine collecting bag opening 12. After the patient collects urine for the first time, the squeezing bag 8 can be squeezed to allow the urine preservative in the squeezing bag 8 to be discharged into the inner bag 2 through the discharge pipe 1 9 and the discharge pipe 2 11. By operating the stirring mechanism, the stirring sheet 6 stirs the urine preservative and urine in real time, and with the help of the liquid level monitoring mechanism, the urine level and urine volume are calculated in real time and displayed, thereby facilitating statistics for nursing staff.
