Referring to fig. 5 and 7, in the clinical auxiliary intelligent control device for drainage, a drainage tube 20 can be combined in a placement groove 11; on one hand, after the middle lower part of the drainage tube 20 is fixed by the placing groove 11, external force interference on the drainage bag 21 caused by unstable factors such as shaking of the middle upper part of the drainage tube 20 is effectively 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 arrangement groove 11 guides the direction of the drainage tube 20, ensures that the middle lower part of the drainage tube 20 can smoothly pass through the two arc-shaped gaps 13 in sequence, and improves the stability of the cooperation of the drainage tube 20 and the two tube rolling mechanisms.

Referring to fig. 6, 8 and 9, when the intelligent control device for clinical drainage assistance is used clinically, in the negative pressure drainage process, each roller 10 revolves in the positive direction for one turn to cause the drainage tube 20 to generate one fluid output, so that the fluid output generated by the same roller 10 in the continuous positive direction revolution process is pulse-type; however, in the clinical drainage auxiliary intelligent control device, the two rollers 10 have the same shape and the same revolution radius, the sum of the output angles β and α corresponding to the two rollers 10 is equal to 360 degrees, the controller 15 makes the two rollers 10 revolve in the positive direction at the same rotation speed in the negative pressure drainage process, and regulates and controls the revolution start time of the two rollers 10, so that the two rollers 10 alternately make the drainage tube 20 perform fluid output, that is, as shown in fig. 8 and 9, when one roller 10 makes the drainage tube 20 perform fluid output, the other roller 10 makes the positive revolution on the other side opposite to the arc gap 13 without making the drainage tube 20 perform fluid output, based on the above technical features and working modes, in the negative pressure drainage process, the two rollers 10 alternately make each fluid output generated by the drainage tube 20 perform non-interval connection, so that the fluid of the drainage tube 20 continuously flows backwards, the pulse effect is weakened or even avoided, so that the flow speed of the accumulated liquid in the drainage tube 20 tends to be uniform in the negative pressure drainage process, and meanwhile, the backflow of the fluid in the drainage tube 20 is also effectively avoided.

Referring to fig. 7 and 8, when the intelligent control device for clinical drainage assistance is used clinically, in the negative pressure drainage process, the necessary pressure difference needs to be provided for negative pressure drainage by means of the elastic capacity of the drainage tube 20, generally speaking, the drainage tube 20 used clinically at present has good elasticity, and in the initial use stage, the elastic performance of the drainage tube 20 is optimal, so that the negative pressure requirement can be met, but as the number of times of extrusion is increased, the elastic performance of the drainage tube 20 located in the arc-shaped gap 13 is weakened, and the negative pressure provided by means of the elastic capacity of the drainage tube 20 is reduced; however, in the use process of the intelligent control device for clinical drainage assistance, the intelligent control device can be placed at a position lower than a patient, and the tube rolling mechanism acts on the middle lower part of the drainage tube 20, so that the required negative pressure requirement can be relieved by the gravitational potential energy of effusion in the drainage tube 20 in the drainage process, the additionally provided negative pressure is smaller in the situation, and even if the elasticity of the drainage tube 20 is weakened, enough negative pressure can be still provided for negative pressure drainage.

Referring to fig. 7 and 11, in the clinical drainage auxiliary intelligent control device, in the use process, the weight of the drainage bag 21 and the accumulated liquid therein is almost all borne by the suspension beam 5, that is, almost all the weight of the drainage bag 21 and the accumulated liquid therein is finally applied to the weighing sensor 19, the weights of the weighing platform 2, the upright post 3, the suspension beam 5 and the drainage bag 21 after placement are constant and constant in the drainage process, and thus the change of the weighing signal output by the weighing sensor 19 is almost all caused by the increase of the accumulated liquid in the drainage bag 21, so that the controller 15 can calculate the weight change speed of the accumulated liquid in the drainage bag 21, that is, the real-time drainage speed, and also can calculate the accumulated weight increase of the accumulated liquid in the drainage bag 21 during the period from the beginning of the drainage to the present time, that is the drainage amount in a single time according to the change state of the weighing signal in the drainage process, therefore, the technical requirement that the controller 15 can calculate the corresponding real-time drainage speed and single real-time drainage quantity based on the change state of the real-time weighing signal can be realized by adopting the prior art;

if the drainage bag is not placed, in the drainage process, the upper end of the drainage bag 21 is fixedly connected with the tail end of the drainage tube 20, the drainage tube 20 inevitably generates certain acting force on the drainage bag 21, and the acting force can be changed along with the deformation of the drainage bag 21, so that certain influence is brought to the data accuracy of the real-time drainage speed and the single real-time drainage quantity; however, in the clinical drainage auxiliary intelligent control device, the setting plate 12 is supported by the telescopic rod 4, the height of the setting plate 12 can be adjusted and locked, and before clinical drainage is implemented, the height of the setting plate 12 is adjusted to enable the part of the drainage tube 20, which is positioned between the setting groove 11 and the drainage bag 21, to be in a natural extension state, so that the acting force of the lower end of the drainage tube 20 on the drainage bag 21 can be reduced, and the influence on the data accuracy of the real-time drainage speed and the single real-time drainage quantity is reduced.

Referring to fig. 2 and 11, in the clinical drainage auxiliary intelligent control device, the controller 15 can adjust the revolution state of the two rollers 10 by adjusting the working state of the driving device 18, the revolution state includes the start and stop of revolution, the rotation direction and the rotation speed, for this purpose, the driving device 18 can be composed of a servo motor and a speed reducer, and in terms of the existing electromechanical control technology, the working state of the servo motor is adjusted by the controller 15, so that the technical requirements are not difficult to achieve.

Referring to fig. 7 and 11, the intelligent control device for assisting clinical drainage 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 control device for clinical drainage assistance is matched with the conventional drainage bag 21 and the drainage tube 20 for use, and the existing structures of the drainage bag 21 and the drainage tube 20 do not need to be changed, so that the intelligent control device is easier to popularize and use; this supplementary intelligent control device that uses of clinical drainage has two kinds of mode of ordinary pressure drainage and negative pressure drainage, can satisfy different drainage operation demands such as pleural effusion drainage, abdominal cavity hydrops drainage, and the suitability is stronger, and application scope is wider, has great clinical spreading value.

Example 2

Referring to fig. 8, in the clinical drainage assistance intelligent control device disclosed in embodiment 1, the roller 10 can extrude the drainage tube 20 in the arc gap 13 to a blocking state after entering the arc gap 13 each time during the forward revolution, and then can move by rolling the drainage tube 20 from the beginning to the end to drive the fluid in the drainage tube 20 to flow backward; in the process, the pressure applied to the draft tube 20 by the roller 10 should be appropriate, on one hand, the draft tube 20 should be squeezed towards the arc-shaped side wall 7 as much as possible, so as to improve the effusion output efficiency, and on the other hand, the roller 10 should be prevented from causing excessive pressure to the draft tube 20, so as to avoid the draft tube 20 located in the arc-shaped gap 13 from being damaged, in order to ensure that the above two effects are balanced, the present embodiment has a further improvement on the matching mode of the two rollers 10 and the two common runners 8, and the specific implementation structure is as follows:

as shown in fig. 12, the roll 10 is fixed in the roll fork 23 through a rotating shaft, a radial hole 26 with a square cross section is formed inwards in the side wall of the common wheel 8, a tensioning pin 24 which is in a square column shape and is in sliding fit with the radial hole 26 is defined in the radial hole 26, a tensioning spring 25 which provides thrust for the tensioning pin is arranged at the bottom of the radial hole 26, and the outer end of the tensioning pin 24 is fixedly connected with the top of the roll fork 23; when the roller 10 and the arc-shaped side wall 7 extrude the drainage tube 20, the tension spring 25 is in a compressed state and is not completely compressed;

therefore, the roller 10 can float along the radial direction of the revolution wheel 8, has a tensioning function, and can improve the effusion output efficiency to the maximum extent and prevent the drainage tube 20 from being damaged due to overlarge pressure exerted by the roller 10 when passing through the arc-shaped gap 13.

Referring to fig. 5, in the clinical drainage assistance intelligent control device disclosed in embodiment 1, the separation of the drainage tube 20 from the two tube rolling mechanisms can be performed only when the two rollers 10 are at the initial positions, and if any one of the components, such as the controller 15, the power supply assembly 17, the driving device 18, and the tube rolling mechanisms, fails, when the clinical drainage assistance intelligent control device is turned off, the two rollers 10 cannot be smoothly moved to the respective initial positions, so that the drainage tube 20 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 embodiment further improves the rollers 10, and the specific implementation structure is as follows:

as shown in fig. 12, a manual turning handle 22 is respectively installed at the outer sides of the roller forks 23 of the two rollers 10, and the two rollers 10 can be manually driven to revolve by the two manual turning handles 22, so that the positions of the two rollers 10 can be adjusted according to clinical requirements, when the clinical drainage auxiliary intelligent control device is turned off and the two rollers 10 cannot be automatically reset, the two rollers 10 can be manually reset by the two manual turning handles 22, and the operation is convenient and fast.

as shown in fig. 13, a signal line 27 for transmitting a weighing signal is connected between the weighing sensor 19 and the controller 15, a threading cavity 29 for extending the signal line 27 is formed in the base 1, the telescopic rod 4 and the setting plate 12, a portion of the signal line 27 located in the telescopic rod 4 has a telescopic section 28 in a shape of a coil spring, and the telescopic section 28 can be telescopic together with the telescopic rod 4.
