[0005] 2. The collected bodily fluids cannot be measured accurately; only estimates are possible.

[0006] 3. The straw at the end that touches the body is not secured, posing a risk of it falling and becoming contaminated.

[0007] 4. The collection device has too few collectors, which is insufficient and affects the efficiency of the operation.

[0008] To address this issue, a body fluid collection device is designed to provide an alternative technical solution. Utility Model Content

[0017] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.

[0018] At the same time, through the above technical solutions, this utility model has at least the following beneficial effects:

[0019] This utility model provides a body fluid collection device. Through the cooperation of a flow meter, a collector, a one-way valve, a gas-liquid separator, a slide valve, an end suction tube, and a slip ring, the body fluid can enter the slide valve through the end suction tube in one go. The slide valve then selects which connecting pipe to enter. After water and gas separation by the gas-liquid separator, the fluid enters the corresponding flow meter. The flow meter detects the amount of flowing body fluid, while the one-way valve prevents backflow during the flow.

[0020] By using slip rings and clips, the connecting tube and the end straw can be held on the object by the corresponding slip rings and clips when not in use, thereby preventing the end straw from falling to the ground and causing pollution.

[0021] By cooperating with the sliding shell, the regulating column, and the closing valve, body fluid is allowed to enter the input end of the sliding shell. At this time, the movement of the regulating column drives the closing valve to move, and the sealing plug achieves a sealing effect at the connection, thereby closing one of the output ends of the sliding shell.

[0022] By using a support shell, an adjusting plate, and multiple supporting plates in combination, the height of the adjusting plate inside the support shell can be adjusted according to the different heights of the gas-water separator. In turn, the bottom of the gas-water separator is supported by multiple supporting plates, thereby preventing the instability of the gas-water separator from causing the connected pipes to loosen.

[0035] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0036] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0037] Example 1

[0038] Reference Figures 1-6 A body fluid collection device includes a base 1. Each of the four corners of the bottom of the base 1 is provided with a brakeable universal wheel, which allows the device to be moved by the brakeable universal wheel. At the same time, the device can be stopped by the brake pedal of the brakeable universal wheel. A handle 7 is fixed to one end of the top of the base 1, so that the device can be moved by pushing the handle 7.

[0039] A bracket 2 is fixed to one end of the top of the base 1. A positioning frame is bolted to the top of the bracket 2. A pressure reducing valve 8 is fixed inside the positioning frame. A main valve 9 is provided on one side of the pressure reducing valve 8, so that the pressure reducing valve 8 can be closed through the main valve 9. Vertical plates 3 are evenly fixed to the top of the base 1, so that the vertical plates 3 are evenly distributed at the other end and both sides of the top of the base 1. A retaining ring 5 is fixed to the top and bottom of one end of the vertical plate 3. A base plate 6 is fixed to the inner side of the retaining ring 5 at the bottom end. A collector 11 is provided on the inner side of the retaining ring 5, so that the collector 11 can only move up and down. Then, the bottom of the collector 11 is supported by the base plate 6.

[0040] The top of the other end plate 3 has a slot 4, and a flow meter 10 is fixed inside the slot 4. The output end of the flow meter 10 is connected to the collector 11 through a pipe. One end of the collector 11 is connected to a pressure reducing valve 8 through a pipe. The pressure reducing valve 8 allows the body fluid, after being detected by the flow meter 10, to enter the collector 11 through the pipe. The input end of the flow meter 10 is connected to a one-way valve 12. The input end of the one-way valve 12 is connected to a gas-liquid separator 13 through a pipe, thus connecting the input end of the one-way valve 12 to the liquid discharge pipe of the gas-liquid separator 13. The input end of the water separator 13 is connected to the connecting pipe 14 through the pipeline, so that the gas-liquid mixture entering the gas-water separator 13 through the connecting pipe 14 can be filtered by the gas-water separator 13 and discharged through the gas output end, and the filtered liquid can be entered into the one-way valve 12 through the pipeline. One end of the two connecting pipes 14 is equipped with a slide valve 15, and the output end of the slide valve 15 is provided with a terminal suction pipe 17, so that the liquid can enter the inside of the slide valve 15 through the terminal suction pipe 17, and after the slide valve 15 is adjusted, it enters the inside of one of the connecting pipes 14.

[0041] In this embodiment, the collector 11 is a disposable sterile collector, and the top cover is provided with an inlet connector and an outlet connector.

[0042] In this embodiment, the gas-water separator 13 and the connecting pipe 14 are connected by a fixing part, which consists of two semicircular plates and bolts. The two semicircular plates are placed symmetrically to form a circle, and the two sides of the two semicircular plates are connected by bolts.

[0043] In this embodiment, the flow meter 10 is a wireless electronic flow meter that can display the flow rate and total flow. The flow meter 10 can also be used multiple times after disinfection.

[0044] In this embodiment, the one-way valve 12 is an existing device, which can be a spring one-way valve, a diaphragm one-way valve, or a duckbill one-way valve.

[0045] A slip ring 19 is provided on the outside of the connecting tube 14. The slip ring 19 is a silicone sliding sleeve. The inner diameter of the slip ring 19 is slightly smaller than the outer diameter of the connecting tube 14, so that the slip ring 19 can slide back and forth against friction on the outside of the connecting tube 14. A clip 20 is connected to one side of the slip ring 19 through a hanging ring. The clip 20 is made of disposable sterile stainless steel, so that the connecting tube 14 is fixed to the bed to prevent it from falling off.

[0046] In this embodiment, the connecting tube 14 is a disposable sterile tubing. In other embodiments, a positioning protrusion is fixed on the outer side of the connecting tube 14 near the slide valve 15, thereby restricting the sliding of the slide ring 19 on the outer side of the connecting tube 14 by the positioning protrusion.

[0047] The sliding valve component 15 includes a pressure plate 16, a closing valve 18, a sliding shell 28, a positioning shell 29, a sealing plug 30, and an adjusting column 31. The input end of the sliding shell 28 is connected to the end suction tube 17, and the output end of the sliding shell 28 is connected to the connecting pipe 14, so that the body fluid inside the end suction tube 17 is diverted inside the sliding shell 28 into one of the output ends, and then into one of the corresponding connecting pipes 14. The positioning shell 29 is fixed inside the end of the sliding shell 28 away from the end suction tube 17. The adjusting column 31 is provided inside the positioning shell 29. The adjusting column 31 is T-shaped. The top of the adjusting column 31 passes through the positioning shell 29 and is fixed with the pressure plate 16, so that the adjusting column 31 can be moved inside the positioning shell 29 by pulling the pressure plate 16.

[0048] Both sides of the positioning shell 29 are fixed with sealing plugs 30. The two sides of the adjusting column 31 are fixed with closing valves 18 through the sealing plugs 30. The sealing plugs 30 can prevent body fluid inside the positioning shell 29 from entering the inner side of the positioning shell 29. The closing valves 18 are slidably connected to the sliding shell 28, so that the movement of the adjusting column 31 drives the two closing valves 18 to move at the same time. This allows one of the closing valves 18 to close one of the output ends of the sliding shell 28, and allows the other output end of the sliding shell 28 to open.

[0049] In this embodiment, the connecting pipe 14 and the sliding valve 15 can be an integral pipe, and the connecting pipe 14, the sliding valve 15 and the end suction pipe 17 can also be an integral pipe. In other embodiments, the connecting pipe 14, the sliding valve 15 and the end suction pipe 17 can also be connected.

[0050] The process of using the body fluid collection device provided by this utility model is as follows: First, the collector 11 is connected to the flow meter 10 and the pressure reducing valve 8 through pipes, and fixed with medical straps. Then, the main valve 9 on the pressure reducing valve 8 is connected to the main pipe of the hospital vacuum system and fixed with medical straps. Then, the main valve 9 is opened, so that the pressure reducing valve 8 adjusts the pressure. Then, the end suction tube 17 is used to draw the corresponding body fluid, so that the body fluid enters the inner side of the slide valve 15 through the end suction tube 17. At this time, by pushing the adjusting column 31, one of the output ends inside the sliding shell 28 is opened, so that the body fluid inside the sliding shell 28 enters the interior of one of the connecting pipes 14 through one of the output ends, and then passes through the corresponding gas-liquid separator. After water-air separation by device 13, the body fluid enters the flow meter 10 through the one-way valve 12. The flow meter 10 allows for precise and rapid monitoring of flow rate and total flow to facilitate appropriate surgical interventions. The one-way valve 12 also prevents backflow of the body fluid. The fluid then enters the collector 11 for storage through the flow meter 10 and the corresponding pipe. When the collector 11 is full, the regulating column 31 is moved by the pressure plate 16, which in turn moves the two closed valves 18. This allows the body fluid inside the sliding shell 28 to enter the other connecting pipe 14 through another output end, and then into other collectors 11. When not in use, the connecting pipe 14 is fixed to the bed by the clamp 20 to prevent it from falling and causing contamination and infection.

[0051] Example 2

[0052] Reference Figures 7-8A body fluid collection device has a base 1 with a support shell 21 bolted to the other end of the top. An adjusting plate 22 is slidably connected to the top of the support shell 21. Support plates 23 are evenly bolted to the top of the adjusting plate 22 at positions corresponding to the gas-liquid separator 13. The bottom of the gas-liquid separator 13 is supported by the support plates 23, and the arc-shaped surface at the top of the support plates 23 prevents the gas-liquid separator 13 from falling inside the multiple support plates 23. An adjusting mechanism for raising and lowering the adjusting plate 22 is installed inside the support shell 21. The adjusting mechanism includes an adjusting drive motor 24, a first gear 25, a second gear 26, and an adjusting threaded column. 27. An adjustment drive motor 24 is fixed at the bottom inside the support shell 21. The output end of the adjustment drive motor 24 is connected to a first gear 25. Both sides of the first gear 25 are meshed with second gears 26. The bottom end of the second gear 26 is rotatably connected to the support shell 21. An adjustment threaded post 27 is fixed at the top end of the second gear 26. The outer side of the top end of the adjustment threaded post 27 is threadedly connected to the adjustment plate 22, so that the rotation of the first gear 25 drives the two second gears 26 to rotate, and the rotation of the two second gears 26 drives the adjustment threaded post 27 to rotate, so that the rotation of the two adjustment threaded posts 27 simultaneously drives the adjustment plate 22 to rise or fall.

[0053] The process of using the body fluid collection device provided by this utility model is as follows: According to the required installation height of the gas-water separator 13, the first gear 25 is rotated by adjusting the power of the drive motor 24. The rotation of the first gear 25 drives the meshing second gear 26 to rotate. The rotation of the second gear 26 drives the adjusting threaded column 27 to rotate. The rotation of the two adjusting threaded columns 27 simultaneously drives the adjusting plate 22 to rise or fall. When the adjusting plate 22 rises, it drives the multiple support plates 23 connected by the top bolts to rise. The rising of the support plates 23 is located on the outer side of the bottom end of the gas-water separator 13, thereby supporting the height of the gas-water separator 13.
