This method brings the following advantages: (1) In order to solve the problem that the existing gynecological and obstetrics nursing catheterization device is difficult to automatically seal the urine container, the present invention proposes an automatic catheterization collection component, which is provided with a separation layer, and uses the properties of water-soluble paper in combination with a magnetic shielding plate to realize the movement of the stretching sealing layer 1 and the stretching sealing layer 2 during the diversion of urine through the diversion groove. Several groups of stretching sealing layers 1 and 2 made of silicone material are wrapped on the catheterization diversion head and the catheterization port to block the catheterization port. While diverting urine, the stretching sealing layer 1 and 2 that are automatically moved and blocked can prevent the sample from spilling during the diversion process, thereby greatly reducing the pollution to the surrounding environment. (2) After the urine diversion is completed, the internal adhesive layer is dissolved with water, and the stretch sealing layer 1 and the stretch sealing layer 2 are separated, but the stretch sealing layer 1 will not fall off. When the urine sample needs to be taken out, several groups of stretch sealing layer 1 and stretch sealing layer 2 are pulled downward to make several groups of sliding steel balls separate from the magnetic adsorption of the adsorption magnet. At this time, the stretch sealing layer 1 is no longer adhered to the stretch sealing layer 2, and the stretch sealing layer 1 is peeled off from the urinary catheter diversion head. Therefore, the suspended solids in the urine remaining near the urinary catheter opening or around the urinary catheter diversion head during the previous diversion process are caught by several collecting hooks. After the entire stretch sealing layer 1 is peeled off, the suspended solids in the urine are also collected by the collecting hooks; (3) This solution only uses a urinary catheter to achieve automatic sealing of the sampling container and automatic classification and collection of solids and liquids in urine samples, which can prevent the spread of urine odor and provide an automated experience.

One end of the first stretching sealing layer 19 is connected in a circumferential array to the top of the collection protection housing 22. One end of the second stretching sealing layer 21 is connected in a circumferential array to the top of the collection protection housing 22. One end of the internal adhesive layer 20 is connected in a circumferential array to the top of the collection protection housing 22. The first stretching sealing layer 19 and the second stretching sealing layer 21 are pasted through the internal adhesive layer 20. The other ends of the first stretching sealing layer 19, the internal adhesive layer 20, and the second stretching sealing layer 21 are connected to the sliding steel balls 18.

[0025] As Figure 3 and Figure 4 shown, the internal collection assembly 2 includes a urinary catheterization through opening 23, a urinary catheterization diversion head 24, and a bottom urine container 25. The bottom urine container 25 is fixedly connected through the adjustment support plate 7. The urinary catheterization diversion head 24 is communicatively disposed on the top of the bottom urine container 25. The urinary catheterization through openings 23 are arranged in a circumferential array on the side of the urinary catheterization diversion head 24.

[0026] As Figure 10 shown, the separation layer 16 is made of water-soluble paper.

[0027] As Figure 12 shown, the first stretching sealing layer 19 and the second stretching sealing layer 21 are made of silica gel. Collection hooks 27 are arrayed on the first stretching sealing layer 19. The internal adhesive layer 20 is made of water-soluble paper and can separate the first stretching sealing layer 19 and the second stretching sealing layer 21 after melting in water.

[0028] As Figure 1 and Figure 2 shown, guide wheels 26 are provided on the side wall of the lifting sliding table 6. The lifting sliding table 6 is fitted and slidably disposed on the moving bracket 3 through the guide wheels 26. One end of the lifting chain 10 is disposed on the moving bracket 3, and the other end of the lifting chain 10 is disposed on the lifting sliding table 6.

[0029] As Figure 3 and Figure 4As shown, the collection protection housing 22 is fixed to the top of the bottom urine container 25.

[0030] As Figure 3 , Figure 4 and Figure 12 As shown, the branch skeleton 11 is fixedly connected to the top of the bottom urine container 25, the top adsorption disc 12 is arranged on the top of the urinary catheter diversion head 24, the stretching sealing layer 19 moves and fits on the branch skeleton 11, and the branch skeleton 11 is located outside the urinary catheter diversion head 24.

[0031] As Figure 13 As shown, there is a magnetic adsorption connection between the sliding steel balls 18 and the adsorption magnet 13, and the sizes of the steel ball seat cushions 15 and the sliding steel balls 18 match.

[0032] During specific use, first move this device to one side of the patient's hospital bed through the moving bracket 3, control the output end of the electric push rod 5 to retract, so one end of the lifting chain 10 connected to the lifting sliding table 6 extends downward, causing the lifting sliding table 6 to slide downward along the moving bracket 3 through the guide wheel 26, so that the adjusting support plate 7 drives the automatic urine collection assembly 1 and the internal collection assembly 2 to move downward synchronously, to adjust the position of the automatic urine collection assembly 1 for convenient subsequent urine collection. Connect to the diversion groove through an external urinary catheter to perform urine collection on the patient. Urine enters the urine collection port 23 along the diversion groove. Initially, the separation layer 16 remains in its original state because it has not come into contact with water. At this time, the separation layer 16 is separated from the sliding steel balls 18 on the branch skeleton 11 through the magnetic shielding plate 17 at its center. The adsorption magnet 13 cannot adsorb a number of groups of sliding steel balls 18 around at this time. At this time, a number of groups of sliding steel balls 18 cannot drive the stretching sealing layer 19, the internal adhesive layer 20, and the stretching sealing layer 21 to move upward. At this time, the urine collection port 23 cannot be blocked by the stretching sealing layer 19, the internal adhesive layer 20, and the stretching sealing layer 21. Dissolve the separation layer 16 with water, so the magnetic shielding plate 17 at its center falls off, enabling the adsorption magnet 13 to normally perform magnetic adsorption on the surrounding sliding steel balls 18. Then a number of groups of sliding steel balls 18 slide along the branch skeleton 11 and are adsorbed into the steel ball seat cushions 15 in the adsorption storage port 14. At this time, the stretching sealing layer 19, the internal adhesive layer 20, and the stretching sealing layer 21 follow the sliding steel balls 18 to stretch and move. A number of groups of stretching sealing layers 19 and stretching sealing layers 21 made of silica gel wrap the urinary catheter diversion head 24 and the urine collection port 23 to block the urine collection port 23. While guiding the flow of urine, the stretching sealing layer 19 and the stretching sealing layer 21 that can perform automatic moving sealing can block the urine collection port 23 to prevent the diffusion of urine odor; After the urine treatment is completed, the internal adhesive layer 20 is melted with water, and the first stretching sealing layer 19 and the second stretching sealing layer 21 are separated. However, the first stretching sealing layer 19 will not fall off. When it is necessary to take out the urine, several groups of the first stretching sealing layer 19 and the second stretching sealing layer 21 are pulled downward, so that several groups of sliding steel balls 18 are separated from the magnetic adsorption of the adsorption magnet 13. At this time, the first stretching sealing layer 19 is no longer adhered to the second stretching sealing layer 21. The first stretching sealing layer 19 is peeled off from the urine guiding and diverting head 24. Then, the suspended solids in the urine remaining near the urine guiding opening 23 or around the urine guiding and diverting head 24 during the previous diversion process are hooked by several collecting hooks 27. After the first stretching sealing layer 19 is completely peeled off, the solid substances in the urine are collected by the collecting hooks 27.
