DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] like Figure 1 and Figure 2 As shown, the hepatobiliary drainage and flushing device of this embodiment includes a solution box 1, an infusion pump 12, a drainage tube 11, a discharge tube 15 and a liquid valve 7. The solution box 1 is provided with a first solution chamber 8 for accommodating flushing liquid, a second solution chamber 9 for collecting drainage liquid and a third solution chamber 10 for collecting waste liquid. The solution box 1 is provided with a scale 6, which is used to measure the drainage liquid volume in the second solution chamber 9 so as to measure the drainage volume. In addition, hooks 2 for hanging are provided on both sides of the solution box 1 so that it can be hung on the side of the bed rail for convenient drainage and flushing.

[0027] The water inlet of the infusion pump 12 is connected with a suction tube 13, which extends into the first solution cavity 8, and the water outlet of the infusion pump 12 is connected with a liquid outlet tube 14; the drainage tube 11 is used to connect with the human body to drain the fluid; the discharge tube 15 is used to discharge the flushing liquid, and one end of the discharge tube 15 is connected with the third solution cavity 10; the liquid valve 7 has four interfaces, three of which are respectively connected with the liquid outlet tube 14, the drainage tube 11 and the discharge tube 15, and the other interface is connected with the second solution cavity 9. During drainage, the drainage tube 11 is connected to the second solution cavity 9 through the liquid valve 7, so as to collect the drainage fluid. When the drainage tube 11 is blocked, the infusion pump 12 is started to flush the drainage tube 11, dredge the drainage tube 11, and discharge the waste liquid into the third solution cavity 10 through the discharge tube 15, so as to collect the flushing waste liquid.

[0028] like Figure 3 to Figure 5 As shown, in order to prevent the drainage liquid in the second solution chamber 9 from backflowing and overflowing, the liquid-passing valve 7 includes a valve housing 701, a valve cover 711, a valve core 703, a spacer sleeve 707 and a first spring 702. The valve cover 711 is connected to the upper end of the valve housing 701, and the interface connected to the drainage tube 11 is located on the valve cover 711. The bottom of the valve housing 701 has an interface connected to the second solution chamber 9. The spacer sleeve 707, the valve core 703 and the first spring 702 are installed in the valve housing 701 from top to bottom. When the valve core 703 is connected to the spacer sleeve 707, the valve core 703 blocks the lower end of the spacer sleeve 707. There is a gap between the valve core 703 and the valve housing 701 for passing liquid. Side holes 710 connected to the interface of the liquid-passing valve 7 are arranged on both sides of the spacer sleeve 707. The liquid outlet pipe 14 and the discharge pipe 15 are connected to the spacer sleeve 707 through the side holes 710.

[0029] The spacer sleeve 707 forms a limiting effect on the valve core 703. Under the action of the first spring 702, the valve core 703 can block the through hole at the lower end of the spacer sleeve 707, so that the drainage liquid in the second solution chamber 9 cannot flow back. When the drainage liquid enters the spacer sleeve 707 from the drainage tube 11, under the action of the drainage liquid, the first spring 702 is compressed, the valve core 703 is separated from the spacer sleeve 707, and the drainage liquid passes through the gap between the valve core 703 and the valve housing 701 into the second solution chamber 9.

[0030] In addition, during the drainage process, the liquid outlet pipe 14 and the drain pipe 15 should be disconnected from the inside of the spacer sleeve 707. For this purpose, the liquid valve 7 also includes two groups of second springs 708, electromagnets 706 and suction blocks 709 arranged in the spacer sleeve 707. The second spring 708 is connected between the electromagnet 706 and the suction block 709. The suction block 709 is made of ferromagnetic material. A through hole is provided on the suction block 709. The through hole and the side hole 710 are misaligned. In this way, the electromagnet 706 can be energized to move the suction block 709 downward, thereby making the through hole and the side hole 710 overlap, thereby facilitating the control of the conduction between the liquid outlet pipe 14, the drain pipe 15 and the spacer sleeve 707.

[0031] In addition, the flushing liquid used to flush and clear the drainage tube 11 should not be discharged into the second solution chamber 9, which will cause inaccurate measurement of the drainage volume. The valve core 703 is made of ferromagnetic material, and protrusions 704 are provided on both sides of the valve core 703. Vertical slide grooves 705 are provided on both sides of the valve shell 701. The protrusion 704 can slide in the slide groove 705. The electromagnet 706 is located above the protrusion 704. When the electromagnet 706 is energized, the valve core 703 is firmly adsorbed, thereby sealing the hole at the lower end of the spacer 707. Even under the pressure of the flushing liquid, the valve core 703 will not move downward to compress the spring, so that the flushing liquid cannot flow into the second solution chamber 9, so that the measurement of the drainage liquid volume is more accurate.

[0032] A box cover 3 is provided at the upper end of the solution box 1 to block the first solution cavity 8, the second solution cavity 9 and the third solution cavity 10. The liquid-passing valve 7 is fixed through the middle of the box cover 3. The infusion pump 12, the liquid outlet pipe 14 and the discharge pipe 15 are fixed at the lower end of the box cover 3. Specifically, corresponding grooves are provided in the box cover 3 to embed the infusion pump 12, the liquid outlet pipe 14 and the discharge pipe 15 into the box cover 3. A mounting hole for mounting a valve shell 701 is provided in the middle of the box cover 3. A convex edge is provided at the lower end of the valve shell 701, and the size of the convex edge is larger than the aperture of the mounting hole. The upper end of the valve shell 701 passes through the box cover 3 and is threadedly connected to the valve cover 711, so that the liquid-passing valve 7 is fixed in the middle of the box cover 3. This can make the structure more compact. A negative pressure port 4 is provided on the box cover 3. The negative pressure port 4 is connected to the third solution cavity 10. The waste liquid that can be flushed and discharged can be drawn out by suction using negative pressure, which helps to open the drainage pipe 11. A control panel 5 is provided at the upper end of the box cover 3, and the control panel 5 is connected to the electromagnet 706 and the infusion pump 12 through a wire, so as to control flushing and discharge of waste liquid.

[0033] like Figure 6 and Figure 7As shown, a drain valve 16 is provided at the bottom of the second solution chamber 9, and the drain valve 16 includes a valve body 161, a third spring 163 and a valve stem 162. The valve body 161 is provided with a cross-shaped cavity, and the vertical cavity of the valve body 161 is connected to the second solution chamber 9. One end of the horizontal cavity of the valve body 161 is closed. The third spring 163 and the valve stem 162 are horizontally arranged in the valve body 161. The third spring 163 is connected between the valve body 161 and the valve stem 162. A through hole is provided on the valve stem 162, and the through hole is misaligned with the vertical cavity of the valve body 161. When the valve stem 162 is pressed, the through hole and the vertical cavity overlap to discharge the drainage liquid. A drain hole 17 and a hole plug 18 are provided at the lower end of the third solution chamber 10. The drain hole 17 is connected to the third solution chamber 10, and the hole plug 18 is blocked in the drain hole 17 to flush the waste liquid.

[0034] When in use, the solution box 1 is hung on the side of the bed rail through the hook 2, below the patient's axillary midline, and the drainage tube 11 is connected to the interface on the valve cover 711. After the drainage fluid enters the spacer sleeve 707, under the action of hydraulic pressure, the valve core 703 moves downward, so that the through hole at the lower end of the spacer sleeve 707 opens, and the second solution chamber 9 collects the drainage fluid. When the drainage tube 11 is blocked by sediment or blood clot during the drainage process, the end of the drainage tube 11 close to the body is clamped by a tube clamp, the negative pressure port 4 is connected to the negative pressure device, and then the infusion pump 12 is started by the control panel 5, and the electromagnet 706 on the side close to the first solution chamber 8 in the spacer 707 is energized to attract the suction block 709 on this side, so that the outlet tube 14 and the spacer 707 are connected, and at the same time, the suction block 709 attracts the valve core 703 to close the lower end of the spacer 707, and the flushing liquid of the first solution chamber 8 enters the drainage tube 11 to flush the drainage tube 11, and then the electromagnet 706 on the side close to the discharge pipe 15 is controlled to be energized to attract the suction block 709 on this side, and the spacer 707 is connected to the third solution chamber 10, and the flushing waste liquid is discharged to the third solution chamber 10 for collection, and finally the waste liquid can be discharged from the drainage hole 17, and the collected drainage liquid can be discharged by pressing the discharge valve 16. The device integrates flushing, drainage and wastewater collection, is convenient for drainage and flushing of the drainage pipe 11, and avoids pipe blockage.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
