B. in the drainage process, the controller enables the driving motor 17 to run at a low speed, and on the premise that the two transverse pressing blocks 12 are kept at initial positions, the position of the longitudinal pressing block 8 is adjusted, namely the extrusion degree of the upper telescopic part 9 opposite to the leading-in end of the drainage tube 20 in a tube gap is adjusted, so that the speed of effusion in the drainage tube 20 is increased or reduced, and finally the real-time drainage speed is approximately equal to the preset drainage speed, namely constant-speed drainage is realized;

C. in the drainage process, the controller calculates the single real-time drainage amount from the initial drainage to the current one, when the single real-time drainage amount reaches the preset single drainage amount, the controller adjusts the position of the longitudinal pressing block 8, so that the upper expansion part 9 extrudes the introduction end of the drainage tube 20 in the tube placing gap to a blocking state, and the quantitative drainage is realized when the drainage is finished;

(2) referring to fig. 5, 6, and 9, in the negative pressure drainage mode:

A. according to the preset drainage starting time, the controller regulates and controls the working state of the driving motor 17 to promote the output of the fluid and the suction of the fluid to be alternately carried out, and the fluid in the drainage tube 20 continuously flows towards the drainage bag, namely, the timing drainage is realized;

B. in the drainage process, the controller adjusts the working state of the driving motor 17 according to the real-time drainage speed, namely adjusts the running states of fluid output and fluid suction, and finally enables the real-time drainage speed to be approximately equal to the preset drainage speed, namely constant-speed drainage is realized; the operation states of the fluid output and the fluid suction comprise start-stop, duration and working frequency of the fluid output and the fluid suction;

C. in the drainage process, the controller calculates the single real-time drainage volume that this drainage is originated to reaching at present in real time, after single real-time drainage volume reaches preset single drainage volume, the controller will make driving motor 17 reverse output, until lower pars contractilis 6 with the end extrusion of drawing forth of drainage tube 20 to block the state and two horizontal briquettings 12 reset to the initial position after the stop motion, this time drainage end and drainage tube 20 was extruded by lower pars contractilis 6 and keep ending the state this moment, realize quantitative drainage promptly.

In the negative pressure drainage mode, after drainage is finished each time, the controller enables the driving motor 17 to reversely output until the lower telescopic part 6 extrudes the leading-out end of the drainage tube 20 to a blocking state and the two transverse pressing blocks 12 are reset to the initial positions and then stop running; the technical characteristics are that when the negative pressure drainage is suspended or finished, the leading-out end of the drainage tube 20 is extruded to a blocking state by the lower telescopic part 6 to avoid the effusion flowing in the drainage tube 20, and the two transverse pressing blocks 12 are both positioned at the initial positions and do not extrude the drainage tube 20, so that the drainage tube 20 in the tube placing gap can be automatically restored to the original state, namely, the cylindrical shape, the long-term flattening state is avoided, the elasticity is greatly reduced, and the stable performance of the subsequent negative pressure drainage is ensured.

Referring to fig. 2, 5 and 6, in the intelligent effusion drainage device, the driving motor 17 has two power output forms of 'forward output' and 'reverse output', and the two power output forms can promote the squeezing mechanism to complete two different effects on the drainage tube 20; the above-mentioned "forward direction" and "reverse direction" are only relative terms, and are only a reference of a power output direction set for convenience of description, because in the concrete implementation, the matching manner of the driving motor 17, the transmission mechanism, the squeezing mechanism and the drainage tube 20 is not limited to a specific one, and in the matching embodiment with different components, the actual turning direction of the output shaft of the driving motor 17 during the fluid output is not necessarily the same, and at the same time, in the matching embodiment with different components, the actual turning direction of the output shaft of the driving motor 17 during the fluid suction is also not necessarily the same; therefore, in the intelligent effusion drainage device, the output state when the drive motor 17 causes the fluid to be output is defined as "forward output", and conversely, "reverse output".

Referring to fig. 5, 6 and 9, when the intelligent effusion drainage device is clinically used, in the negative pressure drainage process, the driving motor 17 under the control of the controller causes the upper telescopic part 9, the lower telescopic part 6 and the two transverse pressing blocks 12 to perform corresponding extrusion action on the drainage tube 20 according to a specific rule, so that negative pressure drainage is realized and the negative pressure drainage state can be controlled; in the negative pressure drainage process, go up pars contractilis 9, pars contractilis 6 down, two horizontal briquettings 12 and be located two structures that constitute of putting drainage tube 20 in the pipe clearance and can regard as a displacement pump, theory of operation and diaphragm pump are very similar, and based on this, drainage adjusting part can realize the negative pressure drainage and can carry out corresponding control to the negative pressure drainage state under the regulation and control of controller, and concrete theory of operation is as follows:

outputting the fluid:

after the primary fluid suction is finished, the longitudinal pressing block 8 is positioned at the lower end of the stroke, and the two transverse pressing blocks 12 are positioned at the initial positions; as shown in fig. 5, when the controller makes the driving motor 17 output in the forward direction, the transmission mechanism drives the longitudinal pressing block 8 to move to the upper end of the stroke, at this time, the upper telescopic part 9 extrudes the introducing end of the drainage tube 20 to a blocking state, the lower telescopic part 6 does not extrude the leading end of the drainage tube, then the transmission mechanism drives the two transverse pressing blocks 12 to move away until reaching a separating state, the two transverse pressing blocks 12 respectively extrude the drainage tube 20 in the gap between the two tubes, the volume of the drainage tube 20 in the gap between the two tubes is gradually reduced, and the internal effusion flows to the direction of the drainage bag 21 through the leading end, thereby realizing fluid output; as shown in fig. 7, in the moving process of the longitudinal pressing block 8 from bottom to top, at the stage before the upper telescopic part 9 extrudes the introducing end of the drainage tube 20 to the blocking state, the leading end of the drainage tube 18 is always extruded by the lower telescopic part 6 to keep the blocking state, that is, the introducing end and the leading end of the drainage tube 18 cannot reach the conducting state simultaneously in the moving process of the longitudinal pressing block 8 from bottom to top, so that the backflow of the fluid in the drainage tube 18 can be avoided, and the one-way output of the fluid can be realized;

fluid intake:

after the primary fluid output is finished, the longitudinal pressing block 8 is positioned at the upper end of the stroke, the two transverse pressing blocks 12 are in a separated state, and the drainage tube 20 in the gap between the two placing tubes is in a flattened state; as shown in fig. 6, when the controller makes the driving motor 17 output reversely, the transmission mechanism firstly drives the longitudinal pressing block 8 to move to the lower end of the stroke, at this time, the lower telescopic part 6 extrudes the leading-out end of the drainage tube 20 to a blocking state, the upper telescopic part 9 does not extrude the leading-in end of the drainage tube, then the transmission mechanism drives the two transverse pressing blocks 12 to approach and finally reset to the initial position, the drainage tube 20 in the tube placing gap gradually recovers to a cylindrical shape by virtue of the elasticity of the drainage tube 20, and the effusion enters the drainage tube 20 in the tube placing gap from the leading-in end along with the gradual increase of the volume, thus realizing the fluid suction; meanwhile, the effusion in the human body also enters the drainage tube 20 along with the suction of the fluid;

the realization of negative pressure drainage:

as shown in fig. 5 and 6, when the fluid output and the fluid suction are performed alternately under the control of the controller, the fluid in the drainage tube 20 can be ensured to flow towards the drainage bag all the time, thereby realizing the negative pressure drainage;

adjusting the negative pressure drainage state:

when the controller enables the driving motor 17 to work in the manner, the negative pressure drainage is realized; when the driving motor 17 stops working and the leading-out end of the drainage tube 20 is extruded to a blocking state by the lower telescopic part 6, the negative pressure drainage is suspended or ended; when the frequency of the fluid output and the fluid suction is increased and the duration of the fluid output and the fluid suction is shortened, the drainage speed can be increased, and otherwise, the drainage speed is reduced.

Referring to fig. 9 and 11, in the above-mentioned intelligent effusion drainage apparatus, the weight-measuring suspension support assembly 4 mainly has two functions, on one hand, the weight-measuring suspension support assembly 4 provides stable support for the drainage bag 21, so that the drainage bag 21 is in a suspension shape and has a basic function of containing drainage effusion in the drainage process, and on the other hand, in the drainage process, the weighing sensor 19 in the weight-measuring suspension support assembly 4 can output a weight signal reflecting the change state of the effusion weight in the drainage bag 21, so as to provide basic data for the data processing of the controller; meanwhile, the weight-counting type suspension support assembly 4 can also adjust the height of the drainage bag 21 within a certain range, so that after the drainage bag 21, the drainage tube 20 and the intelligent effusion drainage device are combined, the part of the drainage tube 20 positioned between the lead-out groove 5 and the drainage bag 21 can be adjusted to be in a natural extension shape; in terms of the prior art, the weight-measuring suspension support assembly 4 can be obtained by slightly improving the structure of the existing electronic scale, and the specific structure has various implementation modes; however, in order to make the weighing suspension support assembly 4 more compact and more stable under the condition that the weighing suspension support assembly 4 meets the above requirements, the weighing suspension support assembly 4 is preferably implemented by adopting the following structure:

as shown in fig. 12, the weight-measuring suspension assembly 4 includes a sliding sleeve 23, a weighing rod 24, a weighing sensor 19 and a suspension portion 3; the sliding sleeve 23 is fixed on the placing plate 15, an inner cavity with an open lower end and a blind upper end is arranged in the sliding sleeve 23, the middle upper part of the weighing rod 24 is positioned in the sliding sleeve 23, the sliding sleeve 23 and the weighing rod 24 can only slide up and down relatively, and the weighing sensor 19 is fixed in the sliding sleeve 23 to provide upward support for the weighing rod 24; the upper end of the suspension part 3 is connected with the lower end of the weighing rod 24 in an inserting way, and a locking mechanism 22 for locking the relative positions of the suspension part and the weighing rod is arranged between the suspension part and the weighing rod; after drainage bag 21 is fixedly connected with hanging part 3, weighing sensor 19 can pick up the weight change state of the accumulated liquid in drainage bag 21 and output a corresponding weight signal;

in addition, generally speaking, most of the drainage bags 21 clinically used at present are provided with a hanging ring at the top for convenient hanging, so that the lower end of the hanging part 3 can be provided with a hook 25 for matching with the hanging ring of the drainage bag 21, and in order to prevent the drainage bag 21 and the hanging part 3 from relatively rotating, the hook 25 can be made of a bent strip-shaped material; meanwhile, the lower end of the hanging part 3 can also be provided with a clamping mechanism which can clamp and fix the upper end of the drainage bag 21;

in the structure of the weight-counting suspension support assembly 4, the suspension part 3 cannot rotate relative to the mounting plate 15, so that stable support can be provided for the drainage bag 21, and the phenomenon that the weight counting is not accurate due to the rotation or shaking of the drainage bag 21 in the drainage process is avoided; the hanging part 3 and the weighing rod 24 can transmit the weight change of the accumulated liquid in the drainage bag 21 to the weighing sensor 19; the hanging part 3 can be adjusted in position in the vertical direction so as to adjust the height of the drainage bag 21; the structure meets the basic function requirement of the weight-measuring type suspension support assembly 4, and has the advantages of simple structure, accurate measurement, small size, compactness and easy implementation.

Referring to fig. 5 and 6, when the intelligent effusion drainage device is clinically used, in the negative pressure drainage process, the drainage tube 20 deforms through the self elastic capacity to provide necessary pressure for negative pressure drainage, generally speaking, the drainage tube 20 clinically used at present has better elasticity, and in the initial stage of negative pressure drainage, the elastic performance of the drainage tube 20 is optimal to meet the aforementioned negative pressure requirement, but as the number of times of extrusion is increased, the elastic performance of the drainage tube 20 positioned in the tube placing gap is weakened, and the maximum negative pressure provided by the self elastic capacity is reduced; however, in the use process of the intelligent effusion drainage device, the intelligent effusion drainage device can be placed at a position lower than a patient, in addition, the extrusion mechanism acts on the middle lower part of the drainage tube 20, the gravitational potential energy of effusion in the drainage tube 20 can relieve the requirement of required negative pressure, the additionally provided negative pressure is smaller under the condition, and even if the elasticity of the drainage tube 20 in the tube placing gap is weakened, enough negative pressure can still be provided for negative pressure drainage.

Referring to fig. 9, 10 and 11, in the clinical use of the intelligent effusion drainage device, the weight of the drainage bag 21 and the effusion inside the drainage bag is almost borne by the hanging part 3, that is, almost the entire weight of the drainage bag 21 and the effusion inside the drainage bag is finally transmitted to the weighing sensor 19 through the hanging part 3, the weights of the hanging part 3 and the installed drainage bag 21 are constant and unchangeable in the drainage process, and thus the weight change sensed by the weighing sensor 19 is all caused by the increase of the effusion in the drainage bag 21, so that the controller can calculate the effusion weight actually drained in unit time, that is, the real-time drainage speed, and can calculate the accumulated weight increase of the effusion in the drainage bag 21 during the period from the beginning of drainage to the present time, that is, the single real-time drainage quantity according to the weight signal continuously fed back by the weighing sensor 19 in real time in the drainage process, therefore, the technical requirement that the controller 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;

based on the working principle adopted by the intelligent effusion drainage device, a certain time interval exists between two adjacent effusion outputs in the drainage process, namely the effusion flows in a pulse mode, so that the unit time based on which the controller calculates and obtains the data of the real-time drainage speed is not too short, and the controller is better to generate at least two fluid outputs in one unit time; in addition, although the effusion is pulsed in the drainage process, the effusion generally does not bring discomfort to the patient, and the pulse feeling generated in the drainage process can be reduced by additionally arranging a buffer container on the drainage tube 20.

Referring to fig. 9, 10 and 11, when the intelligent effusion drainage device is clinically used, a drainage bag 21 is fixedly connected with the tail end of a drainage tube 20 in the drainage process, the drainage tube 20 inevitably generates a certain acting force on the drainage bag 21, the acting force may change along with the deformation of the drainage bag 21, and the force and the change of the force are inevitably picked up by a weighing sensor 19 and fed back to a controller, so that the data accuracy of the real-time drainage speed and the single real-time drainage quantity is influenced to a certain extent; however, in the intelligent effusion drainage device, before clinical drainage is implemented, the height of the drainage bag 21 can be adjusted through the weight-measuring type suspension support assembly 4, so that the part of the drainage tube 20, which is positioned between the lead-out groove 5 and the drainage bag 21, is in a natural extension state, the acting force of the lower end of the drainage tube 20 on the drainage bag 21 can be reduced, and the acting force between the drainage tube 20 and the drainage bag 21 tends to be constant, thereby reducing the influence of the factors on the data accuracy of the real-time drainage speed and the single real-time drainage quantity to the maximum extent.

Referring to fig. 9, 10 and 11, in the above-mentioned intelligent effusion drainage device, the weighing sensor 19 can pick up the change state of the effusion weight in the drainage bag 21, and output a weight signal based on the change state, so as to provide a data basis for the controller to calculate parameters such as real-time drainage speed, single real-time drainage quantity and the like, and thus, the accuracy of the weight signal output by the weighing sensor 19 is a key factor influencing whether the intelligent effusion drainage device can accurately control the drainage process; the weight metering function part in the weight metering type suspension support assembly 4 can be regarded as a conventional weight metering mechanism, and as is well known, the weight metering mechanism can stably and accurately work only in a specific direction, namely, the accuracy of a weight signal output by the weighing sensor 19 can be ensured only when the intelligent effusion drainage device is horizontally placed, otherwise, the gravity generated by effusion in the drainage bag 21 is decomposed, so that the weight signal output by the weighing sensor 19 is inaccurate; generally speaking, with the gradual improvement of ward conditions of medical units, the ground in the ward is relatively flat and tends to be horizontal, so when the intelligent effusion drainage device is placed on the ground of the ward for use, the technical requirement of horizontal placement can be met, and the weight signal output by the weighing sensor 19 can be ensured to be relatively accurate;

step back, even ground in the ward can not reach the requirement that tends to the horizontally, but the accessible fills up the mode of establishing article in base 1 below and adjusts, makes intelligent hydrops drainage device be the level and places, guarantees the accuracy nature of the weight signal of retransmission sensor output among the clinical drainage process.

Referring to fig. 3, in the above-mentioned intelligent fluid-guiding control device, an upper telescopic part 9, a lower telescopic part 6 and a locking mechanism 7 are installed on a longitudinal pressing block 8, the upper telescopic part 9 and the lower telescopic part 6 can be contracted and can be automatically reset to an extended state, and the locking mechanism 7 can lock the upper telescopic part 9 and the lower telescopic part 6 in the contracted state; the arrangement of the upper telescopic part 9, the lower telescopic part 6 and the locking mechanism 7 is used for: on the other hand, as shown in fig. 5 and 6, when the negative pressure drainage is performed, the upper telescopic part 9 and the lower telescopic part 6 are adjusted to be in a telescopic state, and when the on-off state of the inlet end and the outlet end of the drainage tube in the opposite tube gap is switched, the upper telescopic part 9 and the lower telescopic part 6 are in a telescopic characteristic, so that the inlet end and the outlet end are not in a conducting state at the same time, and the backflow of the fluid in the drainage tube can be avoided; on the other hand, as shown in fig. 8, when the normal pressure drainage is performed, the locking mechanism 7 is used to adjust the upper telescopic part 9 and the lower telescopic part 6 to the contraction state, so that the upper telescopic part 9 can extrude the introducing end of the drainage tube in the tube gap to different degrees, and the lower telescopic part 6 can not extrude the leading end of the drainage tube, thereby realizing the adjustment and control of the normal pressure drainage state; in terms of the prior art, the specific structures of the longitudinal pressing block 8, the upper telescopic part 9, the lower telescopic part 6 and the locking mechanism 7 have various embodiments, for example, the upper telescopic part 9, the lower telescopic part 6 can be matched with the longitudinal pressing block 8 in a sliding telescopic manner, an elastic component for driving the upper telescopic part 9 and the lower telescopic part 6 to reset to the extended state is arranged in the longitudinal pressing block 8, and the locking mechanism 7 can be implemented by adopting a structure of a locking bolt; however, in order to make the matching structure of the longitudinal pressing block 8, the upper telescopic part 9, the lower telescopic part 6 and the locking mechanism 7 more compact and the operation more stable, the following method is preferably adopted:

as shown in fig. 13, the upper end and the lower end of the longitudinal pressing block 8 are respectively provided with a blind hole-shaped guide hole 27 extending up and down, the upper telescopic part 9 and the lower telescopic part 6 are respectively composed of a guide post 31 and a top pressing part 32 which are fixedly connected, the two top pressing parts 32 are respectively used for extruding the drainage tube in the gap between the two arranged tubes, the two guide posts 31 are respectively in sliding fit with the two guide holes 27, the guide posts 31 and the corresponding guide holes 27 can only move relatively in the axial direction and cannot be separated, the inner ends of the two guide posts 31 are respectively provided with a blind hole-shaped post cavity 30, and a top spring 28 is arranged between the bottom of the post cavity 30 and the bottom of the corresponding guide hole 27, so that the upper telescopic part 9 and the lower telescopic part 6 can be stretched relative to the longitudinal pressing block 8 and can automatically reset to the stretching state; when the upper telescopic part 9 and the lower telescopic part 6 are in a contracted state, the two guide columns 31 respectively abut against the bottoms of the two guide holes 27, and meanwhile, the two pressing parts 32 respectively abut against the upper end and the lower end of the longitudinal pressing block 8; two positioning pins 26 capable of manually adjusting the axial position are arranged on the longitudinal pressing block 8, and two positioning holes 29 are respectively arranged on the two guide columns 31; the axial position of the positioning pin 26 is manually adjusted, so that the positioning pin 26 does not form a barrier to the relative movement of the guide column 31 and the guide hole 27; when the upper telescopic part 9 and the lower telescopic part 6 are in a contracted state, the axial position of the positioning pin 26 is manually adjusted, so that the positioning pin 26 is matched with the corresponding positioning hole 29, and the relative positions of the guide post 31 and the guide hole 27 are locked.

In the intelligent effusion drainage device, when the driving motor 17 outputs positive direction, the transmission mechanism firstly drives the longitudinal pressing block 8 to move to the upper end of the stroke, and then drives the two transverse pressing blocks 12 to be far away to a separation state; when the driving motor 17 reversely outputs, the transmission mechanism firstly drives the longitudinal pressing block 8 to move to the lower end of the stroke, and then drives the two transverse pressing blocks 12 to approach to the initial position; in terms of the prior art, the technical features are various embodiments, for example, as shown in fig. 14 and 15, the transmission mechanism may be composed of a transmission assembly a and a transmission assembly B, the transmission assembly a is used for driving the longitudinal pressing block 8 to move, the transmission assembly B is used for driving the two transverse pressing blocks 12 to move away from and close to each other, the transmission assembly a is in transmission connection with a driving motor 17 through a torque limiter, the transmission assembly B is in transmission connection with the driving motor 17 through a clutch mechanism, and the clutch mechanism is automatically switched to a closed state when the torque limiter is in an overload protection state; as shown in fig. 14, when the driving motor 17 outputs, power is preferentially transmitted to the transmission assembly a, the transmission assembly a drives the longitudinal pressing block 8 to move, the clutch mechanism is in a separation state, so that the transmission assembly B has no power input, and the two transverse sliding blocks 9 cannot move; as shown in fig. 15, after the longitudinal pressing block 8 reaches the upper end or the lower end of the stroke, the transmission assembly a cannot continue to operate normally because the longitudinal pressing block 8 cannot continue to move, and then the torque limiter provides constant torque to the transmission assembly a, so that the longitudinal pressing block 8 keeps a constant position, and meanwhile, after the torque limiter is in an overload protection state, the clutch mechanism is switched to a closed state, and the transmission assembly B is driven by the driving motor 17 to drive the two transverse pressing blocks 12 to move away from or close to each other; thus, the technical purpose can be achieved;

the transmission assembly A and the transmission assembly B are transmission mechanisms with the function of converting rotary motion into linear motion, the torque limiter and the clutch mechanism are conventional transmission mechanisms commonly used in the electromechanical field, and the working state of the clutch mechanism is determined by the working state of the torque limiter and is easy to realize by adopting the prior art.

Referring to fig. 5, 6 and 9, in the intelligent effusion drainage device, the controller can make the driving motor 17 alternately perform forward output and reverse output, and make the fluid output and the fluid suction alternately perform, thereby implementing negative pressure drainage; in terms of the existing electromechanical control technology, it is not difficult to achieve the above technical purpose, for example, the driving motor 17 adopts a servo motor, the controller can control the output rotation angle and the output direction of the output shaft of the servo motor, in the negative pressure drainage process, the controller enables the driving motor 17 to perform forward output and reverse output according to a preset rotation angle, and after each fluid output is completed, namely two transverse press blocks 12 reach a separation state, the driving motor 17 does not continue to perform forward output any more, but switches to reverse output; after the fluid suction is finished each time, namely after the two transverse pressing blocks 12 are reset to the initial positions, the driving motor 17 does not continue to output reversely, but is switched to output in the forward direction; therefore, the alternation of fluid output and fluid suction can be realized; the specific angle value corresponding to the aforementioned "predetermined rotation angle" is easily determined by calculation and adjustment.

Referring to fig. 8 and 9, in the above-mentioned intelligent effusion drainage device, when performing normal pressure drainage, the controller makes the driving motor 17 run at a low speed, and adjusts the position of the longitudinal pressing block 8, that is, adjusts the degree of extrusion of the upper telescopic part 9 on the introduction end of the drainage tube, on the premise that the two transverse pressing blocks 12 are kept at the initial positions; in terms of the existing electromechanical control technology, it is not difficult to achieve the technical purpose, for example, the driving motor 17 adopts a servo motor, the controller can control the output rotation angle, the output direction and the rotation speed of the output shaft of the servo motor, in the normal pressure drainage process, the controller enables the driving motor 17 to carry out forward output and reverse output in a preset rotation angle range, so as to ensure that the longitudinal pressing block 8 can move between the initial position and the upper end of the stroke, and after the longitudinal pressing block 8 extrudes the leading-in end of the drainage tube to a blocking state, the driving motor 17 cannot continue to carry out forward output; therefore, the two transverse pressing blocks 12 can be kept at the initial positions without extruding the drainage tube 20 in the adjusting process of the normal-pressure drainage state; the angle value corresponding to the aforementioned related rotation angle range is easy to be determined through calculation and debugging.

The intelligent effusion 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 the clinical drainage operation, so that the aim of full-automatic drainage control is fulfilled, the labor burden is saved, and the safety, the stability and the accuracy of the drainage operation are improved; the intelligent effusion drainage device is matched with the conventional drainage bag and drainage tube for use, and the existing structures of the drainage bag and the drainage tube are not required to be changed, so that the intelligent effusion drainage device is easier to popularize and use; the intelligent effusion 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 effusion drainage device is small in size, convenient to move, carry, small in occupied space, high in flexibility and high in clinical popularization value.

Example 2

Referring to fig. 11, in the intelligent effusion drainage device disclosed in embodiment 1, the accuracy of the weighing signal output by the weighing sensor 19 is greatly influenced by whether the intelligent effusion drainage device is horizontally arranged; although the accessible fills up the mode of establishing article and solving in base 1 below when meeting ground levelness relatively poor, nevertheless the operation is got up comparatively trouble, wastes time and energy, for this reason, this embodiment still has following improvement on the structure basis of the intelligent hydrops drainage device that the embodiment disclosed:

as shown in fig. 16 and 17, a first rotating shaft 35 extending horizontally and backwardly is fixed at the rear side of the installation plate 15, and a swing seat 34 is fixed through the first rotating shaft 35 and can swing left and right with a small amplitude; the upper end of the weight-measuring suspension support assembly 4 is connected with the swing seat 34 through the second rotating shaft 33, so that the weight-measuring suspension support assembly 4 can swing back and forth in a small range; the first rotating shaft 35 and the second rotating shaft 33 are vertical to each other; when drainage bag 21 is fixed by hanging part 3, weight-measuring type hanging support assembly 4 is driven by gravity to always maintain a specific direction, and weight sensor 19 can accurately pick up the weight change state of accumulated liquid in drainage bag 21 in the specific direction; the weighing sensor 19 and the controller can adopt wires to transmit data, and can also adopt a wireless technology to transmit data;

after the intelligent effusion drainage device is improved by adopting the structure, the weight-measuring suspension support component 4 has an automatic direction adjusting mechanism, even if the intelligent effusion drainage device is not horizontally arranged in clinical use, the weight-measuring suspension support component 4 can automatically adjust to and maintain a specific direction through left-right swinging and front-back swinging, so that the weighing sensor 19 can stably and accurately work;

in the improved structure, the swing seat 34 can swing left and right in a small range, the weight-measuring suspension assembly 4 can swing front and back in a small range, and the front and back swing and the left and right swing are both in a small range, which means that the change of the relative position of the mounting plate 15 and the weight-measuring suspension assembly 4 is limited in a small range, and the inconvenience brought to the operations of mounting, carrying and the like of the intelligent effusion drainage device due to the unstable relative position of the mounting plate 15 and the weight-measuring suspension assembly 4 is avoided; the specific swing angle range of the small amplitude has no accurate requirement, and the purpose is to ensure that the intelligent effusion drainage device can stably and accurately work under most ground conditions;

meanwhile, the technical requirements that the weight-measuring suspension assembly 4 and the swing seat 34 can only swing back and forth and swing left and right within a small amplitude range are met, and the technical requirements can be easily met by arranging corresponding angle limiting mechanisms 36 between the weight-measuring suspension assembly 4 and the swing seat 34 and between the swing seat 34 and the mounting plate 15;

for the technical requirement that the weight-measuring type suspension support assembly 4 can be automatically adjusted to and maintained in a specific direction under the drive of gravity, when the intelligent effusion drainage device is manufactured, the specific structural form of the weight-measuring type suspension support assembly 4 is debugged, and a standard operation mode is set for the connection mode of the suspension part 3 and the drainage bag 21, so that the technical requirement is realized without difficulty; the specific direction refers to that the gravity generated by the accumulated liquid in the drainage bag 21 tends to be totally fed back to the weighing sensor 19 under the condition that the weight-measuring type suspension support assembly 4 is arranged under the specific direction, so that the weighing sensor 19 can accurately pick up the weight change state of the accumulated liquid in the drainage bag 21.

Example 3

Drainage is a medical means which is commonly used in clinic at present, the clinical drainage process is mostly carried out in a ward, and an intelligent effusion drainage device needs to be frequently moved back and forth between wards and instrument rooms; when the intelligent effusion drainage device disclosed by the embodiment is clinically used, as shown in fig. 1 and 2, the whole device can be stably supported by the base 1, the base 1 is necessarily large and heavy, the intelligent effusion drainage device is labor-consuming to move integrally and is influenced by the base 1, the intelligent effusion drainage device is large in integral volume, large in occupied space during use and poor in flexibility;

generally speaking, the infusion support is a necessary medical device in a ward, the structure is relatively simple, the occupied space is small, and if the intelligent effusion drainage device can be used with the infusion support by removing a heavy base 1 part, a great deal of convenience is brought to the clinical drainage operation; based on the above reasons, the present embodiment has further improvements to the clinical drainage control device disclosed in the foregoing embodiments, and the specific implementation structure is as follows:

referring to fig. 18 and 19, the intelligent effusion drainage device further includes a clamping member 38 that can be clamped and fixed on a transfusion rod 42 of a transfusion stand; a combined seat 41 is arranged at the rear side of the placing plate 15, and the combined seat 41 is connected with the upper end of the upright post 2 in a detachable way; an assembling mechanism is arranged between the clamping member 38 and the combination base 41, and when the clamping member 38 is connected with the combination base 41, the intelligent effusion drainage device can be supported by the infusion rod 42 to work; the combined seat 41 and the upright post 2 can adopt an inserting structure to realize the technical purpose of disassembly and assembly, and the disassembly and assembly operation is more convenient;

from this one, in clinical use, intelligence hydrops drainage device can not rely on base 1 to provide the support, and can cooperate the infusion support that the ward all possesses usually to carry out work for intelligence hydrops drainage device's removal is more convenient, uses more in a flexible way, and the operation is more convenient.

In the above improved structure, the fastening member 38 and the combination seat 41 can be connected by means of the assembling mechanism, in order to ensure that the fastening member 38 can provide sufficient and stable support for the intelligent effusion drainage device, as for the prior art, the assembling mechanism has various embodiments, but in order to ensure the stability after the fastening member 38 and the combination seat 41 are combined and the convenience of disassembling and assembling, the assembling mechanism preferably adopts the following design, and the specific structure is as follows:

as shown in fig. 18, the assembling mechanism is composed of a T-shaped groove 40 disposed on one side of the combining seat 41 and a T-shaped rib 39 disposed on the clamping member 38, the T-shaped groove 40 extends up and down, the upper end is a blind end, the lower end is an open end, the T-shaped rib 39 and the T-shaped groove 40 can be combined, and the damping pad 37 for clamping the T-shaped groove 40 is disposed at the lower end of the T-shaped rib 39;
