The central control operation panel 1 is provided with a power switch 01, a negative pressure meter 02, a display screen 03 and a plurality of buttons 04 in sequence along the length direction of the cabinet. The power switch 01 and the negative pressure meter 02 are arranged side by side, and the negative pressure meter 02 is located above the power switch 01.

[0053] The display screen 03 is a touch screen operation display screen 03 .

[0054] In this embodiment, there are six buttons 04 arranged in a 2x3 matrix.

[0055] An extension tube fixing disinfection device 2 for disinfecting the extension tube is provided next to the central control operation panel 1. The extension tube is plugged into and matched with the opening of the fixed disinfection device 2. By plugging the extension tube into the fixed disinfection device 2, the ultraviolet lamp in the fixed disinfection device 2 irradiates the extension tube for a preset time, thereby completing the disinfection of the extension tube.

[0056] The central control operation panel 1 and the extension tube fixing disinfection device 2 are arranged obliquely upward to reduce light reflection during observation.

[0057] Because the space for placing items on the patient's bedside table during drainage is limited, the cabinet is also provided with a locker 3 and an infectious waste cabinet 4. In this embodiment, there are two lockers 3 and one infectious waste cabinet 4. The lockers 3 and the infectious waste cabinet 4 are arranged side by side and located on the same side of the cabinet. The height of the locker 3 is half the height of the infectious waste cabinet 4.

[0058] An operation grid is also provided in the cabinet. There are at least two operation grids. In this embodiment, the operation grids are located on opposite sides of the storage cabinet 3 and the infectious waste cabinet 4. The operation grids include a first operation grid 5 and a second operation grid 6. The first operation grid 5 and the second operation grid 6 are arranged side by side, and the first operation grid 5 is located above the second operation grid 6. The height of the first operation grid 5 or the second operation grid 6 is the same as that of the infectious waste cabinet 4.

[0059] The two storage cabinets 3 and the first operating compartment 5 are located at the upper position of the cabinet, and the infectious waste cabinet 4 and the second operating compartment 6 are located at the lower position of the cabinet.

[0060] The interiors of the storage cabinet 3, the infectious waste cabinet 4 and the operating grid are smooth and made of corrosion-resistant materials to facilitate cleaning and disinfection.

[0061] The locker 3 is of a pull-out design. A mounting slot with a notch located on the front of the locker is provided inside the locker body. The locker 3 is slidably connected to the mounting slot and is engaged with the mounting slot. When stored in the mounting slot, the front size of the locker 3 matches the notch size of the mounting slot. An arc-shaped gripping slot 31 with a notch facing outward is provided on the front of the locker 3 at the center of the top edge, which conforms to the ergonomic design for the operator to hold and pull the locker 3.

[0062] The infectious waste cabinet 4 includes a waste trough opened in the cabinet body and a sealed door that closes the trough. A delivery port 41 is opened at the upper front of the sealed door. The delivery port 41 is closed by a cover plate 42. One side of the cover plate 42 is hingedly arranged at the inner top position of the delivery port 41.

[0063] A first door handle 43 is also installed on the sealed door to assist in opening the sealed door.

[0064] The opening of the operating compartment faces outward, and a cabinet door 10 is slidably connected in the operating compartment for closing the opening of the operating compartment. The inner bottom surface and the inner top surface of the operating compartment are fixedly installed with slide rails arranged parallel to the side edges, and the top and bottom surfaces of the cabinet door 10 are slidably connected between the two slide rails. When the cabinet door 10 is stored in the operating compartment, one side of the cabinet door 10 abuts against the inner side surface of the operating compartment facing the opening.

[0065] The cabinet door 10 is slidably arranged along the depth direction of the operating grid. When the cabinet door 10 slides to one end of the operating grid opening position, the cabinet door 10 is rotated and arranged in the operating grid. The cabinet door 10 is rotated around the end position and can be flipped 90 degrees toward the opening position of the operating grid.

[0066] When the cabinet door 10 is opened, the cabinet door 10 slides outward from the inside of the operating grid, and when the cabinet door 10 slides to the end of the slide rail, the two ends of the side of the cabinet door 10 that contacts the operating grid are respectively rotated and connected to the outward ends of the two slide rails. At this time, the cabinet door 10 is flipped 90 degrees toward the opening position of the operating grid, and the cabinet door 10 completely closes the opening of the operating grid.

[0067] When storing the cabinet door 10, the cabinet door 10 is flipped 90 degrees toward the opening position away from the operating grid, and the cabinet door 10 slides along the slide rail toward the inside of the operating grid until one side of the cabinet door 10 abuts against the inner side surface of the operating grid facing the opening, so that the cabinet door 10 can be stored inside the operating grid when not in use.

[0068] The cabinet door 10 is an anti-ultraviolet glass door, which can not only play a sealing role, but also facilitate the staff to observe the situation inside the operating grid.

[0069] A second door handle 52 is fixed to a side of the cabinet door 10 facing the outside of the drainage device, for assisting in opening the cabinet door 10 .

[0070] The first and second electronic scales 51 and 61 are respectively installed on the inner bottom surfaces of the first and second operating grids 5 and 6. The output ends of the first and second electronic scales 51 and 61 are electrically connected to the display screen 03 of the central control operation panel 1 via the microcontroller.

[0071] The drainage device body is fixedly installed in the cabinet body in the external space area of ​​the storage cabinet 3, the infectious waste cabinet 4, the first operation compartment 5 and the second operation compartment 6.

[0072] A spare drainage tube storage box 8 with an opening facing upward is fixedly installed at the center of the upper part of the side of the cabinet. The spare drainage tube storage box 8 is in a long strip shape. The height of the spare drainage tube storage box 8 is greater than or equal to the length of the drainage tube in the unfolded state. It is used to store the drainage tube in the unfolded state, so that the operator does not need to unfold the drainage tube when performing the drainage operation, which reduces the preparation time and is conducive to efficient rescue. In this embodiment, the height of the spare drainage tube storage box 8 is equal to the length of the drainage tube in the unfolded state.

[0073] A general waste storage bucket 7 is fixedly installed at the lower center position of the side of the cabinet. The general waste storage bucket 7 is semi-cylindrical, and the opening of the general waste storage bucket 7 is upward. The opening of the general waste storage bucket 7 is closed by a cover plate, and one side of the cover plate is hingedly set on the side of the cabinet.

[0074] Pulleys 9 are fixedly mounted at the four bottom corners of the bottom surface of the cabinet, and the pulleys 9 are universal pulleys 9 that can be braked.

[0075] Reference Figure 2 The drainage device body includes a negative pressure suction cup 62 and a drainage tube 64 . The negative pressure suction cup 62 is fixedly installed in the second operation grid 6 through a fixing frame 65 . The drainage tube 64 is unfolded and placed in the second operation grid 6 .

[0076] The air inlet of the negative pressure suction cup 62 is connected to the drainage tube 64, the air outlet of the drainage tube 64 is connected to an air pump, the input end of the air pump is electrically connected to the microcontroller, a plurality of buttons 04 correspond to different negative pressure values, the input end of the microcontroller is electrically connected to the buttons 04, and the output end of the microcontroller is electrically connected to the negative pressure meter 02 and the input end of the air pump.

[0077] The plurality of buttons 04 include an adult mode button / a child mode button / a baby mode button / a high power button / a low power button, which provide the user with a stable and safe negative pressure value with one button, which is convenient and quick.

[0078] Some buttons 04 can also be remotely configured and expanded according to different usage needs.

[0079] A suction hole 63 is provided at the end of the drainage tube 64 close to the patient, and the suction hole 63 is a negative pressure suction hole.

[0080] The drainage tube 64 is connected to the negative pressure suction tank 62 via an anti-backflow device 621 for preventing backflow of drainage fluid. In this embodiment, the anti-backflow device 621 can be a one-way valve, one end of which is connected to the air outlet of the drainage tube 64 and the other end is connected to the air inlet of the negative pressure suction tank 62.

[0081] The drainage device body also includes a negative pressure liner. The negative pressure liner is located in the negative pressure suction tank 62. The real-time weight measured by the electronic scale is obtained, and based on the weight of the negative pressure liner and the weight of the flushing fluid, the weight of the drainage fluid = the real-time weight - (the weight of the negative pressure liner + the weight of the flushing fluid). There is no need to obtain the weight of the drainage fluid through personal experience evaluation and observation of the liquid level scale, and the weight of the drainage fluid can be accurately recorded, which is conducive to providing accurate prompts for clinical judgment.

[0082] In this embodiment, the flushing liquid can be empty, in which case the weight of the flushing liquid is the weight of the empty cup; the flushing liquid can be sterile saline, in which case the weight of the flushing liquid is the weight of the sterile saline plus the weight of the empty cup.

[0083] The purpose of measuring the weight of the drainage fluid can also be achieved by adding or subtracting the weight of the negative pressure liner and the weight of the flushing fluid during a specific drainage process.

[0084] Therefore, with the help of the negative pressure instrument 02 and the electronic scale, the drainage negative pressure value and the drainage fluid weight can be displayed in real time on the central control operation panel 1.

[0085] The mobile intelligent negative pressure drainage device can also alarm based on the preset negative pressure threshold and drainage fluid weight threshold, and provide fault alarm type and handling suggestions.

[0086] Specifically, based on the doctor's historical drainage data and diagnostic data, a summary is made, and the negative pressure threshold, the corresponding fault type and the corresponding processing suggestions are preset to form a negative pressure monitoring table, and the drainage fluid weight threshold, the corresponding fault type and the corresponding processing suggestions are preset to form a weight monitoring table; the microcontroller obtains the real-time negative pressure value measured by the negative pressure instrument 02 and the drainage fluid weight value measured by the electronic scale, and compares them with the negative pressure monitoring table and the drainage fluid monitoring table, respectively.

[0087] When the real-time negative pressure value is within the negative pressure threshold range, the microcontroller searches the negative pressure monitoring table for the corresponding fault type and corresponding processing suggestions, and displays the real-time negative pressure value, the corresponding fault type and the corresponding processing suggestions on the display screen 03.

[0088] When the drainage fluid weight value is within the drainage fluid weight threshold range, the microcontroller searches the weight monitoring table for the corresponding fault type and corresponding processing suggestions, and displays the drainage fluid weight value, the corresponding fault type and the corresponding processing suggestions on the display screen 03.

[0089] A liquid level sensor is installed in the negative pressure inner tank, the output end of the liquid level sensor is electrically connected to the input end of the microcontroller, and the output end of the microcontroller is connected to an alarm.

[0090] In this embodiment, the liquid level sensor may be a float type liquid level sensor, which is mounted on the drainage device body through a connecting flange and is located inside the negative pressure liner. The float type liquid level sensor floats on the drainage liquid surface based on the principle of equal volume of displaced liquid. When the drainage liquid level changes, the float type liquid level sensor also moves up and down, and changes the liquid level position into an electrical signal.

[0091] When the liquid level measured by the liquid level sensor exceeds a preset safety value, the microcontroller receives a trigger signal from the liquid level sensor and inputs a control signal to the alarm. The alarm responds to the microcontroller and sounds an alarm to automatically remind you to replace the negative pressure liner.

[0092] In this embodiment, a safety warning line is printed at 2 / 3 of the height of the negative pressure inner tank, so that the height value corresponding to the safety warning line is used as a preset safety value.

[0093] Therefore, the negative pressure liner not only has an anti-backflow function to prevent liquid from overflowing into the instrument; it also has the function of automatically reminding you to replace the liner after reaching the safety warning line, thereby achieving the purpose of double protection.
