[0002] An artificial liver machine is an important medical device used to treat diseases such as liver failure. The metabolic and detoxification functions of the liver of patients with liver failure are severely damaged. The artificial liver machine temporarily replaces some of the liver's functions through extracorporeal circulation, helping to clear toxins and metabolic waste from the body, correct metabolic disorders in the body, buy time for the recovery of liver function, or create conditions for liver transplantation.

[0003] During the operation of the artificial liver machine, a large amount of waste liquid is generated, which needs to be properly collected and treated. In the existing technology, the artificial liver machine is usually connected to the waste liquid bag through a connecting tube, so that the waste liquid bag can collect the waste liquid generated during the operation of the artificial liver machine. However, in order to adapt to daily use, a longer part of the connecting tube will be hung or stacked on the artificial liver machine, which causes inconvenience in the daily work of medical staff and easily causes the connecting tube to fall off, resulting in leakage of waste liquid and pollution.

[0005] The utility model provides the following technical solution: a waste liquid bag for an artificial liver machine, comprising a waste liquid bag body and a connecting tube, wherein the waste liquid bag body is provided with a liquid inlet tube, and both ends of the connecting tube are respectively provided with a first connector and a second connector, the first connector and the second connector are respectively detachably connected to the liquid inlet tube and the liquid outlet tube of the artificial liver machine, the waste liquid bag body is detachably connected to a wiring harness mechanism for wiring the connecting tube, and the wiring harness mechanism is provided with a locking mechanism;

[0006] The wiring harness mechanism includes a contact block, a cylindrical member fixedly connected to the contact block, and a stopper fixedly connected to the cylindrical member. The diameter of the cylindrical member is smaller than that of the contact block and the stopper, and a portion of the connecting tube is wound around the cylindrical member.

[0007] Furthermore, the waste liquid bag body is provided with an adhesive piece, and the contact block is adhered to the waste liquid bag body through the adhesive piece.

[0008] Furthermore, the locking mechanism includes a bracket fixedly connected to the stop block, a rotating part rotatably connected to the bracket, an extrusion part fixedly connected to the rotating part, a groove opened on the stop block, and a limiting component provided on the contact block for limiting the extrusion part.

[0009] Furthermore, the limiting assembly includes a sliding sleeve fixedly connected to the contact block, a wedge block slidably connected in the sliding sleeve, and a spring connected between the sliding sleeve and the wedge block.

[0010] Furthermore, a pulling block is provided on one end of the wedge-shaped block away from the extrusion piece, and the pulling block is integrally formed with the wedge-shaped block.

[0011] Furthermore, the extrusion piece is cylindrical or elliptical.

[0012] Furthermore, the waste liquid bag also includes an adjustment mechanism arranged on the connecting tube, the adjustment mechanism includes a slide rail, a receiving groove opened on the slide rail, two sliders symmetrically slidingly connected on both sides of the slide rail, and a roller rotatably connected between the two sliders, a part of the roller is located in the receiving groove, and the connecting tube passes through the receiving groove.

As a result, the connecting tube wound around the cylindrical member cannot move along the radial direction of the cylindrical member through the action of the rotating member, thereby preventing the connecting tube from scattering from the cylindrical member. Further, the setting of the block can prevent the connecting tube wound around the cylindrical member from moving upward and scattering, thereby achieving the effect of arranging the connecting tube so that it is not easy to scatter. At the same time, the connecting tube can be torn off from the waste liquid bag main body through the bundle mechanism, so that the bundle mechanism can be used on the next waste liquid bag main body, thereby achieving the effect of saving costs.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] A waste liquid bag for an artificial liver machine, such as Figures 1-4 As shown, it includes a waste liquid bag body 1 and a connecting tube 4, wherein the waste liquid bag body 1 is provided with a liquid inlet tube 2, and a first connector 3 and a second connector 5 are respectively provided at both ends of the connecting tube 4, and the first connector 3 and the second connector 5 are respectively detachably connected to the liquid inlet tube 2 and the liquid outlet tube of the artificial liver machine, and the waste liquid bag body 1 is detachably connected to a wiring harness mechanism 6 for wiring the connecting tube 4, and the wiring harness mechanism 6 is provided with a locking mechanism 7;

[0026] The wiring mechanism 6 includes a contact block 62, a cylindrical member 63 fixedly connected to the contact block 62, and a stopper 64 fixedly connected to the cylindrical member 63. The diameter of the cylindrical member 63 is smaller than that of the contact block 62 and the stopper 64. A portion of the connecting tube 4 is wound around the cylindrical member 63.

[0027] When the waste liquid bag needs to be used, the operator can first connect the first connector 3 of the connecting tube 4 to the liquid inlet tube 2. The first connector 3 and the liquid inlet tube 2 can be threadedly connected. In other embodiments, the liquid can also be directly plugged in. Then, a part of the connecting tube 4 can be wrapped around the cylindrical member 63 as needed, thereby achieving the effect of tidying up the connecting tube 4 and preventing the medical staff from accidentally pulling the connecting tube 4 during work, causing the connecting tube 4 to fall off and causing waste liquid leakage. Then, the second connector 5 of the connecting tube 4 is connected to the liquid outlet pipe of the artificial liver machine. The second connector 5 and the liquid outlet pipe of the artificial liver machine can be threadedly connected. In other embodiments, direct plugging can be performed, and the waste liquid will flow into the waste liquid bag body 1 through the connecting tube 4, thereby achieving proper collection of the waste liquid. After the second connector 5 is connected to the liquid outlet pipe of the artificial liver machine, the operator can operate the locking mechanism 7 to limit the connecting tube 4 wrapped around the cylindrical member 63 to prevent the connecting tube 4 wrapped around the cylindrical member 63 from scattering. The first connector 3 is detachably connected to the liquid inlet pipe 2, which makes it convenient for the operator to replace the waste liquid bag body 1. The setting of the block 64 can prevent the connecting tube 4 wrapped around the cylindrical member 63 from moving upward and scattering.

[0028] The waste liquid bag body 1 is provided with an adhesive member 61 , and the contact block 62 is adhered to the waste liquid bag body 1 through the adhesive member 61 .

[0029] Among them, the operator can tear off the protective film of the adhesive piece 61, and then stick the contact block 62 on the adhesive piece 61, thereby connecting the contact block 62 to the waste liquid bag body 1. When the waste liquid is collected, the operator can tear off the wire bundling mechanism 6 from the waste liquid bag body 1 and use the wire bundling mechanism 6 on the next waste liquid bag body 1, thereby saving costs.

[0030] The locking mechanism 7 includes a bracket 71 fixedly connected to the stop block 64, a rotating member 72 rotatably connected to the bracket 71, an extrusion member 73 fixedly connected to the rotating member 72, a groove 74 provided on the stop block 64, and a limiting component provided on the contact block 62 for limiting the extrusion member 73; the limiting component includes a sliding sleeve 75 fixedly connected to the contact block 62, a wedge block 76 slidingly connected in the sliding sleeve 75, and a spring 78 connected between the sliding sleeve 75 and the wedge block 76; a pulling block 77 is provided on the end of the wedge block 76 away from the extrusion member 73, and the pulling block 77 and the wedge block 76 are integrally formed; the extrusion member 73 is cylindrical or elliptical.

[0031] After the operator has wound the connecting pipe 4 around the cylindrical member 63, the operator can rotate the rotating member 72 to rotate it in the direction close to the contact block 62. The rotation of the rotating member 72 drives the extruding member 73 to rotate together. The extruding member 73 will contact the wedge block 76 during rotation. At this time, the extruding member 73 will squeeze the wedge block 76. The wedge block 76 moves and the spring 78 stretches. Finally, the extruding member 73 will pass over the wedge block 76 and the spring 78 will reset. The reset of the spring 78 drives the wedge block 76 to move in the direction close to the extruding member 73. The wedge block 76 will block the extruding member 73. Thus, through the action of the rotating member 72, the connecting pipe 4 wound around the cylindrical member 63 will not be able to move along the radial direction of the cylindrical member 63, thereby preventing the connecting pipe from 4 is scattered from the cylindrical member 63. When it is necessary to remove the connecting tube 4 from the cylindrical member 63, the operator can use the pulling block 77 to move the wedge block 76 away from the extrusion member 73. The spring 78 is stretched, and the wedge block 76 will no longer block the extrusion member 73. At this time, the operator can rotate the rotating member 72 into the groove 74. The groove 74 can prevent the rotating member 72 from affecting the medical staff in winding the connecting tube 4 around the cylindrical member 63 or removing it from the cylindrical member 63. Then the operator releases the pulling block 77, the spring 78 is reset, the wedge block 76 is also reset, and the rotating member 72 rotates into the groove 74. The rotating member 72 will no longer block the connecting tube 4. The operator can then remove the connecting tube 4 from the cylindrical member 63.

[0032] like Figure 5As shown, the waste liquid bag also includes an adjusting mechanism 8 provided on the connecting tube 4, the adjusting mechanism 8 includes a slide rail 81, a receiving groove 84 provided on the slide rail 81, two sliders 82 symmetrically slidingly connected on both sides of the slide rail 81, and a roller 83 rotatably connected between the two sliders 82, a portion of the roller 83 is located in the receiving groove 84, and the connecting tube 4 passes through the receiving groove 84.

[0033] When the operator needs to adjust the flow rate of waste liquid entering the waste liquid bag body 1, the operator can slide the roller 83. The sliding of the roller 83 will squeeze the connecting tube 4, thereby flattening the connecting tube 4 at the adjustment mechanism 8, and the flow rate of the waste liquid will become smaller. When the flow rate does not need to be adjusted, the sliding roller 83 can be used to stop squeezing the connecting tube 4.

[0034] like Figure 6 As shown, the waste liquid bag also includes a liquid locking mechanism 9 arranged on the liquid inlet tube 2, and the liquid locking mechanism 9 includes a planar portion 91, a wedge-shaped portion 95 arranged on the side of the planar portion 91 close to the liquid inlet tube 2, a first arc-shaped portion 92 and a second arc-shaped portion 93 respectively arranged on both sides of the planar portion 91, and a locking portion 96 and a bending portion 94 respectively arranged on the first arc-shaped portion 92 and the second arc-shaped portion 93, and the liquid inlet tube 2 passes through the first arc-shaped portion 92 and the second arc-shaped portion 93 in sequence.

[0035] When it is necessary to cut off the flow of waste liquid into the waste liquid bag main body 1, the operator can press the bent portion 94, and the wedge-shaped portion 95 and the bent portion 94 will squeeze the liquid inlet pipe 2, so that the waste liquid will not be able to flow into the waste liquid bag main body 1. Then, the bent portion 94 is pressed into the inner side of the clamping portion 96. The clamping portion 96 can limit the bent portion 94 to prevent the bent portion 94 from rebounding and loosening the liquid inlet pipe 2. When it is no longer necessary to cut off the flow of waste liquid into the waste liquid bag main body 1, the operator can move the bent portion 94 out of the inner side of the clamping portion 96, so that the bent portion 94 rebounds to the outer side of the clamping portion 96, and the bent portion 94 will no longer squeeze the liquid inlet pipe 2, so that the waste liquid flows into the waste liquid bag main body 1.

[0036] To sum up, by winding the connecting tube 4 around the cylindrical member 63, and then rotating the rotating member 72 to rotate it in the direction close to the contact block 62, the rotation of the rotating member 72 drives the extruding member 73 to rotate together, and the wedge block 76 blocks the extruding member 73. As a result, through the action of the rotating member 72, the connecting tube 4 wound on the cylindrical member 63 will not be able to move along the radial direction of the cylindrical member 63, thereby preventing the connecting tube 4 from scattering from the cylindrical member 63. Further, the setting of the stop block 64 can prevent the connecting tube 4 wound on the cylindrical member 63 from moving upward and scattering, thereby achieving the effect of arranging the connecting tube 4 so that it is not easy to scatter. At the same time, it can be torn off from the waste liquid bag main body 1 through the wiring mechanism 6, so that the wiring mechanism 6 can be used on the next waste liquid bag main body 1, which can achieve the effect of saving costs.

In this specification, schematic representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0038] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
