Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] Please see Figures 1-6 The present invention will describe the above technical solution in detail through the following embodiments:

[0031] An intraoperative drainage device for operating room care, comprising:

[0032] A drainage support 1 is provided, and several drainage bottles 2 are attached to the outside of the drainage support 1. The drainage bottles 2 are connected in series through a drainage tube 3.

[0033] The drainage bracket 1 includes a column 13. The bottom end of the column 13 is connected to a movable wheel 12 via a support leg 11. Four brackets 14 are evenly fixedly installed on the bottom side of the column 13. The top surface of the bracket 14 is provided with a sliding groove 15. Each bracket 14 is fixedly installed with a buckle 16 by screws on the top of the bracket 14 and on the side of the column 13.

[0034] Both bracket 14 and buckle 16 are made of plastic and molded in one piece.

[0035] The drainage bottle 2 includes a bottle body 21, with a bottle cap 22 snapped onto the top of the bottle body 21. An inlet pipe 23 and a drain pipe 24 are provided through the middle of the bottle cap 22.

[0036] The bottom of the bottle body 21 is slidably connected to the slide groove 15, the bottom surface of the bottle body 21 abuts against the bracket 14, and the middle part of the bottle body 21 is engaged with the buckle 16.

[0037] Bottle body 21 is used to contain contaminated liquid. Bottle cap 22 is used to seal the top of bottle body 21.

[0038] The bottom of the inlet pipe 23 and the outlet pipe 24 extend into the bottle body 21, with the bottom surface of the inlet pipe 23 being lower than the bottom surface of the outlet pipe 24.

[0039] Liquid enters the bottle body 21 through the inlet pipe 23. When the liquid level is higher than the bottom of the outlet pipe 24, it will be discharged from the outlet pipe 24.

[0040] The drainage line 3 includes several connecting pipes 32. One end of the connecting pipe 32 is connected to the drainage bottle 2, and the other end of the connecting pipe 32 is connected to a selection line. The selection line is used to disconnect one or more of the drainage bottles 2 without affecting the operation of the drainage device.

[0041] The drainage pipe 3 includes a fixing box 31, which is fixedly installed on the top of the column 13 by screws. The connecting pipe 32 is snapped onto the side of the fixing box 31 and passes through the inner and outer sides of the fixing box 31.

[0042] There are eight connecting tubes 32 in total, and two on each side of the fixing box 31.

[0043] The heads of the inlet pipe 23 and the outlet pipe 24 are snapped into the connecting pipe 32.

[0044] The inlet tube 23 and outlet tube 24 of the same drainage bottle 2 are inserted into the two connecting tubes 32 on one side of the fixing box 31.

[0045] The drainage tube 3 also includes a negative pressure tube 33 and a suction tube 34. The negative pressure tube 33 is connected to the drain tube 24 of the first drainage bottle 2 through a connecting tube 32, and the suction tube 34 is connected to the inlet tube 23 of the last drainage bottle 2 through a connecting tube 32. The negative pressure tube 33 is used to connect to the negative pressure device, and the suction tube 34 is used to connect to the suction head.

[0046] The negative pressure device employs a well-known central negative pressure system, which is a known medical negative pressure system. Alternatively, a well-known negative pressure suction device can be used. The suction head is a well-known disposable Yankee suction head, connected to the connecting tube 32 via a disposable silicone tubing.

[0047] The selected pipeline includes a three-way valve. The middle pipe of the three-way valve is connected to the inlet pipe 23 of the drainage bottle 2 via a connecting pipe 32. The right pipe of the three-way valve is connected to the outlet pipe 24 of the second drainage bottle 2. The left pipe of the three-way valve is connected to a three-way valve 39.

[0048] The three-way valve uses a known medical disposable three-way valve and is made entirely of plastic.

[0049] When the pipe in the middle of the three-way valve is connected to the pipe on the right, the inlet pipe 23 of the first drainage bottle 2 is connected to the outlet pipe 24 of the second drainage bottle 2 through the three-way valve.

[0050] When the pipe in the middle of the three-way valve is connected to the pipe on the left, the inlet pipe 23 of the first drainage bottle 2 is connected to the three-way valve 39.

[0051] One end of the three-way valve 39 is connected to the three-way valve via a flexible hose, and the other end is connected to the drain pipe 24 of the third drainage bottle 2 via a connecting pipe 32. The last port is connected to a one-way valve, which is connected to the inlet pipe 23 of the drainage bottle 2 connected to the right side of the three-way valve via the connecting pipe 32.

[0052] When the middle pipe of the three-way valve is connected to the right-side pipe, the inlet pipe 23 of the drainage bottle 2 connected to the right-side pipe of the three-way valve is connected to the one-way valve. The one-way valve is connected to the outlet pipe 24 of the third drainage bottle 2 through the three-way valve 39. At this time, the negative pressure device is activated, and the contaminated liquid can enter from the inlet pipe 23 of the third drainage bottle 2, and then exit from the outlet pipe 24 of the third drainage bottle 2. After passing through the three-way valve 39, it enters the second drainage bottle 2 from the inlet pipe 23 of the second drainage bottle 2, and then enters the first drainage bottle 2 from the outlet pipe 24 of the second drainage bottle 2 through the three-way valve.

[0053] When the middle pipe of the three-way valve is connected to the left pipe, the drain pipe 24 of the third drainage bottle 2 is connected to the three-way valve via the three-way valve 39, thus connecting to the inlet pipe 23 of the first drainage bottle 2. At this time, the negative pressure device is activated, allowing contaminated liquid to flow from the drain pipe 24 of the third drainage bottle 2, through the three-way valve 39, and into the first drainage bottle 2 via its inlet pipe 23. Due to the presence of the check valve, the second drainage bottle 2 does not participate in drainage and can be removed. After removal, outside air cannot enter the pipe through the check valve.

[0054] Selectable pipelines can be stacked. When stacked, the middle pipe of the three-way valve of the second selected pipeline is connected to the tee 39 of the previous selected pipeline, and the tee 39 of the previous selected pipeline is no longer connected to the connecting pipe 32.

[0055] In this embodiment, two selection pipelines are included, wherein the three-way valve includes a first three-way valve 37 and a second three-way valve 38, and the one-way valve includes a first one-way valve 35 and a second one-way valve 36.

[0056] The middle pipe of the first three-way valve 37 is connected to the inlet pipe 23 of the first drainage bottle 2 via the connecting pipe 32. The pipe on the left side of the first three-way valve 37 is connected to the first one-way valve 35 via the three-way valve 39. The pipe on the right side of the first three-way valve 37 is connected to the drain pipe 24 of the second drainage bottle 2 via the connecting pipe 32. The first one-way valve 35 is connected to the inlet pipe 23 of the second drainage bottle 2 via the connecting pipe 32.

[0057] The three-way valve 39 between the first three-way valve 37 and the first one-way valve 35 is connected to the middle pipe of the second three-way valve 38. The pipe on the right side of the second three-way valve 38 is connected to the drain pipe 24 of the third drainage bottle 2 through the connecting pipe 32. The pipe on the left side of the second three-way valve 38 is connected to the second one-way valve 36 through the three-way valve 39. The second one-way valve 36 is connected to the drain pipe 24 of the third drainage bottle 2 through the connecting pipe 32.

[0058] The three-way valve 39 between the second three-way valve 38 and the second one-way valve 36 is connected to the drain pipe 24 of the last drainage bottle 2 via the connecting pipe 32. The drain pipe 24 of the last drainage bottle 2 is connected to the suction pipe 34 via the connecting pipe 32.

[0059] In this embodiment, when using this device, the operator should ensure that all pipe connections are secure, and snap the ends of the inlet pipes 23 and outlet pipes 24 of the four drainage bottles 2 into the connecting pipes 32. The inlet pipe 23 and outlet pipe 24 of the same drainage bottle 2 are inserted into the two connecting pipes 32 on one side of the fixing box 31.

[0060] Connect the negative pressure tube 33 to the negative pressure device using a flexible hose, and connect the suction tube 34 to the suction head using a flexible hose.

[0061] The middle and right pipes of the first three-way valve 37 are connected, and the middle and right pipes of the second three-way valve 38 are connected. At this time, the four drainage bottles 2 are connected in series.

[0062] Activate the negative pressure device and insert the suction head into the liquid to be suctioned. The contaminated liquid enters the last drainage bottle 2 from the inlet pipe 23. After the last drainage bottle 2 is full, the liquid is discharged from the drain pipe 24 of the last drainage bottle 2. After passing through the three-way valve 39 and the second one-way valve 36, it enters the third drainage bottle 2 through the inlet pipe 23. When the third drainage bottle 2 is full, the liquid is discharged from the drain pipe 24 of the third drainage bottle 2. After passing through the second three-way valve 38, the three-way valve 39 and the first one-way valve 35, it enters the second drainage bottle 2 through the inlet pipe 23.

[0063] At this point, you can choose to replace the already full third drainage bottle 2. For example... Figure 5As shown, the middle pipe and the left pipe of the control second three-way valve 38 are connected. At this time, the negative pressure of the negative pressure device is not transmitted through the third drainage bottle 2, but directly to the three-way valve 39 between the second three-way valve 38 and the second one-way valve 36. Due to the presence of the second one-way valve 36, the third drainage bottle 2 does not participate in the drainage. The liquid in the last drainage bottle 2 is discharged from the drain pipe 24, passes through the three-way valve 39, and then passes through the second three-way valve 38, the three-way valve 39 and the first one-way valve 35, and enters the second drainage bottle 2 from the inlet pipe 23.

[0064] At this point, disconnect the inlet pipe 23 and outlet pipe 24 of the third drainage bottle 2 from the connecting pipe 32 and remove the third drainage bottle 2. After replacing it with a new drainage bottle 2, connect the middle pipe and the right pipe of the second three-way valve 38. At this time, the liquid will enter the new drainage bottle 2.

[0065] Alternatively, you can wait until the second drainage bottle 2 is full of liquid before replacing it. The replacement method is to connect the middle pipe and the left pipe of the first three-way valve 37, then remove the second drainage bottle 2 and replace it with a new one, and then connect the middle pipe and the right pipe of the first three-way valve 37 again.

[0066] Alternatively, you can choose to replace the two middle drainage bottles 2 at once. This requires ensuring that the middle pipes of the first three-way valve 37 and the second three-way valve 38 are connected to the left-side pipe. Remove the two middle drainage bottles 2 and replace them with new ones, then ensure that the middle pipes of the first three-way valve 37 and the second three-way valve 38 are connected to the right-side pipe.
