referring to fig. 1, 6, 7 and 11, in the intelligent medical drainage device, the suspension beam 11 is supported by the lower part of the weighing rod 13 and is positioned below the placing plate 6, and the placing mode of the suspension beam 11 has two technical requirements, on one hand, the suspension beam 11 always extends along the width direction of the placing plate 6, thereby ensuring that the drainage bag 23 supported by the suspension beam and the placing plate 6 tend to be in the same plane, thereby reducing the space occupied by the intelligent medical drainage device in clinical use, and on the other hand, the suspension beam 11 can be adjusted up and down along the weighing rod 13 and can be locked, so that after the drainage bag 23, the drainage tube 21 and the intelligent medical drainage device are combined, the height of the drainage bag 23 can be adjusted according to the requirement, so that the part of the drainage tube 21 between the clamping groove 5 and the drainage bag 23 is in a natural extension state, and the acting force of the drainage tube 21 on the drainage bag 23 is reduced; based on the above two technical requirements, the connection mode of the suspension beam 11 and the weighing rod 13 can adopt the following structure:

Referring to fig. 2 and 3, a sleeve 17 is arranged in the middle of the suspension beam 11, the sleeve 17 is sleeved on the middle lower part of the weighing rod 13 and can only move up and down along the weighing rod 13, the lower end of the weighing rod 13 is provided with threads and is provided with an adjusting nut 18, and the adjusting nut 18 provides upward support for the sleeve 17; therefore, the height of the suspension support beam 11 can be conveniently adjusted by rotating the adjusting nut 18, and the operation is quick and convenient.

Referring to fig. 5, in the intelligent medical drainage device, the revolution modes of the two rollers 4 are divided into a forward revolution and a reverse revolution, wherein the forward and reverse are relative only and are referred to only as a rotation direction set for convenience of description, because in the specific implementation process, the relative position of the drainage tube 21 and the two rollers 4 is not limited to a specific one, and the actual revolution direction required by the rollers 4 to drive the effusion in the drainage tube 21 to flow from the human body to the drainage bag 23 is influenced by the relative position of the drainage tube 21 and the rollers 4, therefore, in the foregoing description, the rotation direction which can drive the effusion in the drainage tube 21 to flow from the human body to the drainage bag 23 in the revolution process of the rollers 4 is defined as the forward direction, and vice versa; meanwhile, the actual rotational directions of the two rolls 4 in the forward revolution are not necessarily the same due to the above reasons.

Referring to fig. 4 and 6, in the intelligent medical drainage device, a clamping groove 5 is formed in the front side of a placement plate 6, on one hand, the clamping groove 5 can fix the middle lower part of a drainage tube 21, so that external force interference caused by unstable factors such as shaking of the middle upper part of the drainage tube 21 on a drainage bag 23 is avoided, and the data accuracy and stability of real-time drainage speed and single real-time drainage quantity are improved; on the other hand, the clamping groove 5 is used for guiding the trend of the drainage tube 21, ensuring that the middle lower part of the drainage tube 21 can smoothly and sequentially pass through the two arc-shaped gaps 7, and improving the stability of the cooperation of the drainage tube 21 and the two tube rolling mechanisms.

Referring to fig. 5, 8 and 9, when the intelligent medical drainage device is used clinically, in the negative pressure drainage process, each roller 4 revolves in the positive direction for one circle to cause the drainage tube 21 to generate one fluid output, so that the fluid output generated by the same roller 4 in the continuous positive revolution process is pulse-type; however, in the intelligent medical drainage device, the two rollers 4 have the same shape and the same revolution radius, and the sum of the output angles β and α corresponding to the two rollers 4 is equal to 360 degrees, for example, in the negative pressure drainage process, the controller 9 makes the two rollers 4 revolve forward at the same rotation speed, and regulates and controls the revolution start time of the two rollers 4, that is, controls the timing when the two rollers 4 respectively make the drainage tube 21 output fluid, so that the two rollers 4 can make the drainage tube 21 output fluid alternately, that is, as shown in fig. 8 and 9, when one roller 4 makes the drainage tube 21 output fluid, the other roller 4 makes the drainage tube 21 rotate forward at the other side opposite to the arc-shaped gap 7 without making the drainage tube 21 output fluid, based on the above technical features and working modes, in the negative pressure drainage process, the two rollers 4 make the drainage tube 21 generate each fluid output capable of being connected without interval, the technical purpose of continuously moving the fluid in the drainage tube 21 backwards is realized, the pulse effect is weakened or even avoided, the flow rate of the accumulated fluid in the drainage tube 21 tends to be uniform in the negative pressure drainage process, and meanwhile, the backflow of the fluid in the drainage tube 21 is also avoided.

referring to fig. 6 and 8, when the intelligent medical drainage device is used clinically, in the negative pressure drainage process, the drainage tube 21 needs to provide necessary pressure for negative pressure drainage by means of the elastic capacity of the drainage tube 21, generally speaking, the drainage tube 21 used clinically at present has better elasticity, and in the initial use stage, the elasticity of the drainage tube 21 is optimal, so that the negative pressure requirement can be met, but as the number of times of extrusion is increased, the elasticity of the drainage tube 21 located in the arc-shaped gap 7 is weakened, and the maximum negative pressure provided by means of the elastic capacity of the drainage tube is reduced; however, in the use process of the intelligent medical drainage device, the intelligent medical drainage device can be placed at a position lower than a patient, in addition, the tube rolling mechanism acts on the middle lower part of the drainage tube 21, the gravitational potential energy of accumulated liquid in the drainage tube 21 can relieve the requirement of required negative pressure in the drainage process, the additionally provided negative pressure is smaller in the situation, and even if the elasticity of the drainage tube 21 is weakened, enough negative pressure can be still provided for negative pressure drainage.

Referring to fig. 6, 7 and 11, in the clinical use process of the intelligent medical drainage device, the weight of the drainage bag 23 and the accumulated liquid therein is almost completely borne by the suspension beam 11, that is, almost the entire weight of the drainage bag 23 and the accumulated liquid therein is finally transmitted to the weighing sensor 19 through the weighing rod 13, the weights of the weighing rod 13, the suspension beam 11 and the drainage bag 23 after being arranged are constant and constant in the drainage process, so that the weight change sensed by the weighing sensor 19 is almost completely caused by the increase of the accumulated liquid in the drainage bag 23, so that the weight change speed of the accumulated liquid in the drainage bag 23, that is, the real-time drainage speed can be calculated by the controller 9 according to the weight signal continuously fed back by the weighing sensor 19 in real time in the drainage process, the accumulated weight of the accumulated liquid in the drainage bag 23 during the period from the beginning of the current drainage, namely the single real-time drainage quantity, therefore, the technical requirement that the controller 9 can calculate the real-time drainage speed and the single real-time drainage quantity based on the weight signal continuously fed back by the weighing sensor 19 in real time can be realized by adopting the prior art;

referring to fig. 6 and 7, if the drainage bag 23 cannot be placed, the drainage bag 23 is fixedly connected with the tail end of the drainage tube 21 in the drainage process, the drainage tube 21 inevitably generates a certain acting force on the drainage bag 23, and the acting force may change along with the deformation of the drainage bag 23, so that the data accuracy of the real-time drainage speed and the single real-time drainage quantity is influenced; however, in the intelligent medical drainage device, the height of the suspension beam 11 can be adjusted and locked, and before clinical drainage is implemented, the height of the suspension beam 11 is adjusted to enable the part of the drainage tube 21 between the clamping groove 5 and the drainage bag 23 to be in a natural extension state, so that the acting force of the lower end of the drainage tube 21 on the drainage bag 23 can be reduced, and the influence of the acting force on the data accuracy of real-time drainage speed and single real-time drainage quantity is reduced.

Referring to fig. 6, 7 and 11, in the intelligent medical drainage device, the weighing sensor 19 indirectly senses the change state of the weight of the accumulated liquid in the drainage bag 23 through the weighing rod 13, the suspension beam 11 and other components, and outputs a weight signal to provide a data basis for the controller 9 to calculate parameters such as real-time drainage speed, single real-time drainage quantity and the like; therefore, the accuracy of the weight signal output by the weighing sensor 19 is a key factor influencing whether the intelligent medical drainage device can accurately control the drainage process; the structure and the functions formed by the weighing sensor 19, the weighing rod 13 and the suspension beam 11 can be regarded as a conventional weighing mechanism, and as is well known, the metering precision of the weighing mechanism is greatly influenced by the arrangement direction, namely, the weighing rod 13 is kept vertical in the clinical use process of the intelligent medical drainage device, so that the precision of a weight signal output by the weighing sensor 19 can be improved to the maximum extent; along with the gradual improvement of ward conditions of medical units, the ground in the ward is relatively flat and tends to be horizontal, meanwhile, the existing infusion support is relatively accurate to manufacture, and the extension direction of the infusion rod 22 tends to be vertical, so that the technical requirement that the weighing rod 13 is vertical after the mounting plate 6 is fixed on one side of the infusion rod 22 by the aid of the clamping and fixing piece 15 is relatively easy to realize, and the accuracy of weight signals output by the retransmission sensor can be ensured;

in a step-by-step manner, even if the ground in the ward cannot meet the requirement of approaching to the horizontal state, the infusion rod 22 can be made to approach to the vertical state by adjusting the placement mode of the infusion support base, so that the accuracy of the weight signal output by the retransmission sensor in the clinical drainage process is ensured; moreover, the infusion support used at present has increasingly rich functions, and the bases of many infusion supports have the function of adjusting the levelness, so that the adjustment of the vertical degree of the infusion rod 22 is very convenient and fast.

referring to fig. 1 and 11, in the intelligent medical drainage device, the controller 9 can adjust the revolution state of the two rollers 4 by adjusting the working state of the driving device 16, the revolution state includes the start and stop, the rotation direction and the rotation speed of the revolution, and the position of the roller 4 can be adjusted based on the control of the revolution state, as for the prior art, the driving device 16 can be composed of a servo motor and a speed reducer, in the prior art of electromechanical control, the working state of the servo motor is adjusted by the controller 9, and the technical requirements are not difficult to achieve.

referring to fig. 6 and 11, the intelligent medical drainage device adopts an intelligent design, and can realize functions of timed drainage, constant-speed drainage, quantitative drainage and the like according to preset drainage parameters in clinical drainage operation, so that the purpose of intelligent automatic drainage control is achieved, the labor burden is saved, and the safety, stability and accuracy of drainage operation are improved; the intelligent medical drainage device is matched with the conventional drainage bag 23 and the drainage tube 21 for use, and the existing structures of the drainage bag 23 and the drainage tube 21 are not required to be changed, so that the intelligent medical drainage device is easier to popularize and use; the intelligent medical drainage device has two working modes of normal-pressure drainage and negative-pressure drainage, can meet different drainage operation requirements of pleural effusion drainage, abdominal effusion drainage and the like, and has stronger applicability and wider application range; meanwhile, the intelligent medical drainage device is small in size, convenient to move and carry, small in occupied space and high in flexibility, and has great clinical popularization value, and the intelligent medical drainage device is matched with the infusion rod 22 for use in clinical use.

therefore, the roller 4 can float along the radial direction of the revolution wheel 2, has a tensioning function, can provide sufficient extrusion for the drainage tube 21 to ensure the output efficiency of accumulated liquid when passing through the arc-shaped gap 7, and can prevent the drainage tube 21 from being damaged due to overlarge pressure applied by the roller 4.

Referring to fig. 4, in the intelligent medical drainage device disclosed in embodiment 1, the separation of the drainage tube 21 from the two tube rolling mechanisms can only be performed when the two rollers 4 are at the initial positions, and if any one of the components, such as the controller 9, the power supply component 14, the driving device 16, and the tube rolling mechanisms, fails, the two rollers 4 cannot be smoothly moved to the respective initial positions when the intelligent medical drainage device is shut down, so that the drainage tube 21 cannot be smoothly separated from the two tube rolling mechanisms, the medical operation efficiency is reduced, and even the medical treatment time may be delayed, for this reason, the present embodiment further improves the rollers 4, and the specific implementation structure is as follows:
