Their efficacy is mainly obtained through physical means, not through pharmacological, immunological or metabolic means, or although these means are involved, they only play an auxiliary role.

[0003] During gastrointestinal surgery, waste fluids are typically drained and collected using a gastrointestinal drainage device. However, existing gastrointestinal drainage devices are inconvenient to adjust internal pressure, and the dosage of drainage fluid cannot be accurately displayed. Therefore, there is an urgent need for a pressure-adjustable and display-reading gastrointestinal drainage device to overcome these shortcomings. Utility Model Content

[0004] The purpose of this invention is to provide a pressure-adjustable and display-reading gastrointestinal drainage device, which has the advantages of convenient adjustment and accurate display, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure-adjustable and display-reading gastrointestinal drainage device, comprising a drainage component, a display and measurement component, a pressurizing component, and a sealing component. The drainage component is disposed within the inner cavity of the display and measurement component, the pressurizing component is disposed to the right of the display and measurement component, and the sealing component is disposed to the right of the pressurizing component. The drainage component includes a drainage bag body, a drain valve, an electric control valve, a controller, and a pressure valve. The display and measurement component includes a positioning box, a control panel, a pressure sensor, and a first spring. The pressurizing component includes a sealing barrel, a piston, a pressure rod, a positioning groove, and a conduit. The sealing component includes an annular cylinder, an mounting rod, a second spring, a threaded tube, a sealing nut, and a sealing disc.

[0006] Furthermore, the drain valve is connected to the top of the drainage bag body, the electric control valve is connected to the right side of the top of the drainage bag body, the pressure valve is connected to the center of the top of the drainage bag body, and the controller is fixedly installed on one side of the top of the drainage bag body.

[0007] Furthermore, the control panel is fixedly installed on the front of the positioning box, and the first spring is evenly installed on the bottom of the drainage bag body, with the bottom of the first spring fixedly connected to the bottom of the inner cavity of the positioning box.

[0008] Furthermore, the pressure sensor is fixedly installed at the center of the bottom of the positioning box cavity, the conduit is connected to the top of the electric control valve, and the sealing barrel is connected to the right side of the conduit.

[0009] Furthermore, the positioning groove is formed at the top of the inner cavity of the sealing barrel, the piston is disposed in the inner cavity of the sealing barrel, and the pressure rod slides in the inner cavity of the positioning groove.

[0010] Furthermore, the bottom of the pressure rod is fixedly connected to the top of the piston, the annular cylinder is connected to the right side of the sealing barrel, the mounting rod is fixedly installed in the inner cavity of the annular cylinder, and the threaded pipe is connected to the right side of the annular cylinder.

[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:

[0013] This invention utilizes a drainage component to store drainage fluid, a display and measurement component to weigh the drainage fluid, and a control panel to provide prompts to operators. A pressurization component regulates the pressure within the drainage bag's inner cavity, and a sealing component controls the air intake and exhaust of the pressurization component. When pressurizing the inner cavity of the drainage bag, the pressure rod is first moved upwards, causing the piston to move upwards. The suction force pushes the sealing plate to the left and into the inner cavity of the drainage bag. Then, the controller opens the electric control valve. Next, the pressure rod is pressed, causing the piston to move downwards. The piston then guides the airflow through the conduit into the inner cavity of the drainage bag. Simultaneously, the mounting rod moves the sealing plate to the right, pressurizing the left side of the threaded tube. The system employs a sealing mechanism. When the pressure valve detects that the pressure has reached a certain level, the electric control valve closes, blocking the airflow into the inner cavity of the drainage bag. When the pressure inside the drainage bag is high, the drain valve is opened to release the fluid. When negative pressure needs to be applied to the inner cavity of the drainage bag, the sealing nut is connected to the threaded tube, the right side of the threaded tube is sealed, and the electric control valve is opened. The pressure rod is then raised to the designated position, and the suction force reduces the pressure inside the drainage bag. When weighing the drainage fluid, the pressure sensor measures the weight, which is then converted into a liquid level reading and displayed on the control panel. This system offers the advantages of convenient adjustment and accurate display, solving the problems of existing gastrointestinal drainage devices where it is inconvenient to adjust the internal pressure and the drainage fluid dosage cannot be accurately displayed.

[0021] More specifically, by setting the sealing component 4 to control the air intake and exhaust of the pressurizing component 3, when pressurizing the inner cavity of the drainage bag body 11, the pressure rod 33 is first moved upward, and under the action of the pressure rod 33, the piston 32 moves upward. Under the action of suction, the airflow pushes the sealing disc 46 to the left and enters the inner cavity of the drainage bag body 11. Then, under the action of the controller 14, the electric control valve 13 is controlled to open. Immediately afterwards, the pressure rod 33 is pressed, and the pressure rod 33 drives the piston 32 to move downward. Under the action of the piston 32, the airflow is introduced into the inner cavity of the drainage bag body 11 through the conduit 35. At the same time, the mounting rod 42 drives the sealing disc 46 to move to the right to seal the left side of the threaded tube 44. When the pressure valve 15 detects that the pressure has reached a certain level, the electric control valve 13 closes, blocking the airflow from entering the inner cavity of the drainage bag body 11. When the pressure inside the drainage bag body 11 is high, the drain valve 12 is opened to discharge the fluid. When it is necessary to draw negative pressure into the inner cavity of the drainage bag body 11, the sealing nut 45 is directly connected to the threaded pipe 44, the right side of the threaded pipe 44 is blocked, and the electric control valve 13 is opened. The pressure rod 33 is then raised to the designated position, and the pressure inside the drainage bag body 11 is reduced under the action of suction. When the drainage fluid is weighed, the pressure sensor 23 weighs the fluid and converts the weight into liquid level. The measured reading is displayed on the surface of the control panel 22, which has the advantages of convenient adjustment and accurate display.

More specifically, the drainage bag body 11 is weighed by setting the pressure sensor 23.

[0025] In some embodiments, the positioning groove 34 is formed at the top of the inner cavity of the sealing barrel 31, the piston 32 is disposed in the inner cavity of the sealing barrel 31, and the pressure rod 33 slides in the inner cavity of the positioning groove 34. More specifically, the positioning groove 34 is used to limit the pressure rod 33 to prevent the pressure rod 33 from shaking during movement.

[0026] In some embodiments, the bottom of the pressure rod 33 is fixedly connected to the top of the piston 32, the annular cylinder 41 is connected to the right side of the sealing barrel 31, the mounting rod 42 is fixedly installed in the inner cavity of the annular cylinder 41, and the threaded tube 44 is connected to the right side of the annular cylinder 41.

[0028] Working principle:

[0029] Step 1: When pressurizing the inner cavity of the drainage bag body 11, first move the pressure rod 33 upward. Under the action of the pressure rod 33, the piston 32 moves upward. Under the action of suction, the airflow pushes the sealing disc 46 to the left and enters the inner cavity of the drainage bag body 11. Then, under the action of the controller 14, the electric control valve 13 is controlled to open. Next, press the pressure rod 33, which drives the piston 32 to move downward. Under the action of the piston 32, the airflow is introduced into the inner cavity of the drainage bag body 11 through the conduit 35. At the same time, the mounting rod 42 drives the sealing disc 46 to move to the right to seal the left side of the threaded tube 44.

[0030] Step 2: When the pressure valve 15 detects that the pressure has reached a certain requirement, the electric control valve 13 closes, blocking the airflow into the inner cavity of the drainage bag body 11. When the pressure inside the drainage bag body 11 is high, the drain valve 12 is opened to discharge the fluid. When it is necessary to draw negative pressure into the inner cavity of the drainage bag body 11, the sealing nut 45 is directly connected to the threaded pipe 44, the right side of the threaded pipe 44 is blocked, and the electric control valve 13 is opened. The pressure rod 33 is raised to the designated position. Under the action of suction, the pressure inside the drainage bag body 11 is reduced. When the drainage fluid is weighed, the weight is measured under the action of the pressure sensor 23, and the weight is converted into liquid level. The measurement reading is displayed on the surface of the control panel 22, which has the advantages of convenient adjustment and accurate display.
