C. in the drainage process, the controller calculates the single real-time drainage quantity from the initial drainage to the current one, when the single real-time drainage quantity reaches the preset single drainage quantity, the controller adjusts the push plate 16 to the initial end of the stroke, at the moment, the drainage is finished, and the drainage tube 21 is extruded by the lower active pressure block 6 to keep a cut-off state, so that the quantitative drainage is realized;

in the negative pressure drainage mode, after drainage at every turn, the controller adjusts the push plate 16 to the stroke beginning, the technical characteristics of the utility model lie in that, when the negative pressure drainage is suspended or ended, after the push plate 16 is adjusted to the stroke beginning, the lower movable pressing block 6 is locked at the stroke end by the locking mechanism 20 to make the drainage tube 21 keep the blocking state, and the upper movable pressing block 8 and the middle movable pressing block 7 automatically reset to the respective stroke beginning, thereby not extruding the drainage tube 21, so that the drainage tube 21 in the tube placing gap can be automatically restored to the original state, namely cylindrical shape, the long-term flattening state is avoided, the elasticity is greatly reduced, and the stable proceeding of the subsequent negative pressure drainage is ensured.

When the intelligent medical clinical drainage control device is used clinically, in the negative pressure drainage process, the drainage adjusting component enables the upper movable pressing block 8, the middle movable pressing block 7 and the lower movable pressing block 6 to perform corresponding extrusion on the drainage tube 21 according to a specific rule under the regulation and control of the controller, so that negative pressure drainage is realized, and the negative pressure drainage state can be adjusted; in the negative pressure drainage process, the structure that fixed briquetting 10, upper movable briquetting 8, well activity briquetting 7, lower activity briquetting 6 and put drainage tube 21 in the pipe clearance and constitute can be regarded as a displacement pump, and theory of operation is very similar with the diaphragm pump, and based on this, the 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 specific theory of operation is as follows:

outputting the fluid:

when the drainage adjusting assembly causes the drainage tube 21 to finish the primary fluid suction, the push plate 16 is positioned at the initial end of the stroke, the upper movable pressing block 8 and the middle movable pressing block 7 are positioned at the initial ends of the respective strokes, and the lower movable pressing block 6 is locked by the locking mechanism 20 and positioned at the terminal end of the stroke; when the push plate 16 moves from the stroke beginning end to the stroke end under the control of the controller: when the push plate 16 passes through the front section of the stroke, as shown in fig. 5, the telescopic ejector rod 18 keeps the extension state and pushes the upper movable press block 8 to the stroke end step by step; when the push plate 16 passes through the middle section of the stroke, the telescopic ejector rod 18 continues to push the upper movable pressing block 8, so that the upper movable pressing block 8 is maintained at the stroke end, the telescopic ejector rod 18 is compressed passively along with the movement of the push plate 16, meanwhile, in the stage, the push plate 16 drives the locking mechanism 20 to release the locking effect on the lower movable pressing block 6, and the lower movable pressing block 6 automatically resets to the stroke starting end; after the lower active pressure block 6 is reset to the initial end of the stroke, at the moment, the lower active pressure block 6 and the middle active pressure block 7 do not extrude the drainage tube 21, the lower end of the drainage tube 21 in the tube placing gap is communicated with the drainage bag 22, the controller drives the push plate 16 to move at the rear section of the stroke, as shown in fig. 6, the upper active pressure block 8 is still maintained at the terminal end of the stroke to extrude the upper end of the drainage tube 21 in the tube placing gap to the blocking state, the telescopic ejector rod 18 continues to be compressed passively, meanwhile, in the stage, the push plate 16 pushes the middle active pressure block 7 and the lower active pressure block 6 to move towards the respective stroke terminals, the drainage tube 21 in the tube placing gap is extruded by the middle active pressure block 7 and the lower active pressure block 6 to change the volume, and the accumulated liquid in the drainage bag 22 flows, so that the fluid output is realized; in the fluid output process, before the lower movable pressing block 6 is reset towards the direction of the stroke starting end, the upper movable pressing block 8 is positioned and stopped at the stroke terminal end, so that the fluid in the drainage tube 21 can be prevented from flowing back;

fluid intake:

when the drainage adjusting assembly prompts the drainage tube 21 to finish primary fluid output, the push plate 16 is positioned at the stroke terminal, and the upper movable pressing block 8, the middle movable pressing block 7 and the lower movable pressing block 6 are positioned at the respective stroke terminals; as shown in fig. 7, when the push plate 16 moves from the end of the stroke to the beginning of the stroke under the control of the controller: when the push plate 16 passes through the rear section of the stroke, the middle movable pressing block 7 moves towards the direction of the stroke starting end firstly, the lower movable pressing block 6 is still kept at the stroke end under the locking action of the locking mechanism 20, meanwhile, the telescopic ejector rod 18 extends along with the movement of the push plate 16, but the upper movable pressing block 8 is still kept at the stroke end; when the push plate 16 passes through the middle section of the stroke, the locking mechanism 20 is not driven to release the locking effect on the lower movable pressing block 6, namely, the lower movable pressing block 6 is still locked at the stroke end, the telescopic ejector rod 18 gradually extends to the longest state along with the movement of the push plate 16, but the upper movable pressing block 8 still continues to stay at the stroke end; when the push plate 16 passes through the front section of the stroke, the telescopic ejector rod 18 moves integrally along with the push plate 16, the upper movable pressing block 8 is gradually reset to the stroke starting end, even if the upper end of the drainage tube 21 in the tube placing gap is communicated with the human body, the lower movable pressing block 6 is continuously maintained at the stroke end to press the lower end of the drainage tube 21 in the tube placing gap to a blocking state, when the pushing plate 16 is reset to the stroke beginning end, the middle movable pressing block 7 and the upper movable pressing block 8 are reset to the respective stroke starting ends in sequence, and the drainage tube 21 in the tube gap is not extruded any more, the drainage tube 21 squashed by the upper movable pressing block 8 and the middle movable pressing block 7 in the previous fluid output process is gradually restored to be cylindrical by the elasticity of the drainage tube, the front end of the drainage tube 21 generates negative pressure along with the increase of the volume, and effusion in a human body is sucked into the drainage tube 21, so that the fluid suction is realized; in the process of fluid suction, before the upper movable pressing block 8 is reset towards the direction of the stroke starting end, the lower movable pressing block 6 is already positioned and stays at the stroke terminal end, so that the fluid in the drainage tube 21 can be prevented from flowing back;

the realization of negative pressure drainage:

as shown in fig. 6 and 7, when the drainage regulating assembly causes the drainage tube 21 to alternately circulate for fluid output and fluid suction, the fluid in the drainage tube 21 can be ensured to flow backwards all the time, i.e. negative pressure drainage is realized;

adjusting the negative pressure drainage state:

when the controller enables the drainage adjusting component to work according to the mode, the negative pressure drainage is realized; when the drainage adjusting assembly stops working and the push plate 16 is reset to the initial end of the stroke, the lower movable pressure block 6 extrudes the drainage tube 21 to a blocking state, and the negative pressure drainage is suspended or finished; when the operating frequency of fluid output and fluid suction is increased and the duration of the fluid output process and the fluid suction process is shortened, the drainage speed can be increased, and otherwise, the drainage speed is reduced.

Referring to fig. 2, 9 and 10, in the above-mentioned intelligent medical clinical drainage control device, 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 22 to make the drainage bag 22 in a suspension shape and have a basic function of containing drainage effusion during drainage, on the other hand, in the drainage process, the weighing sensor 15 in the weight-measuring type suspension support assembly 4 can output a weight signal reflecting the weight change state of the accumulated liquid in the drainage bag 22, basic data are provided for data processing of the controller, meanwhile, the weight-measuring suspension support assembly 4 can also adjust the height of the drainage bag 22 within a certain range, so that after the drainage bag 22, the drainage tube 21 and the intelligent medical clinical drainage control device are combined, the part of the drainage tube 21 between the eduction groove 5 and the drainage bag 22 can be adjusted to a natural stretching 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. 11, the weight-measuring suspension assembly 4 includes a sliding sleeve 24, a weighing rod 25, a load cell 15 and a suspension portion 3; the sliding sleeve 24 is fixed on the placing plate 12, an inner cavity with an open lower end and a blind upper end is arranged in the sliding sleeve 24, the middle upper part of the weighing rod 25 is positioned in the sliding sleeve 24 and the weighing rod and the sliding sleeve can only slide up and down relatively, and the weighing sensor 15 is fixed in the sliding sleeve 24 and provides upward support for the weighing rod 25; the upper end of the suspension part 3 is connected with the lower end of the weighing rod 25 in an inserting way, and a locking mechanism 23 for locking the relative positions of the suspension part and the weighing rod is arranged between the suspension part and the weighing rod; after the drainage bag 22 is fixedly connected with the hanging part 3, the weighing sensor 15 can pick up the weight change state of the accumulated liquid in the drainage bag 22 and output a corresponding weight signal;

in addition, generally speaking, most of the drainage bags 22 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 26 for matching with the hanging ring of the drainage bag 22, and in order to prevent the drainage bag 22 and the hanging part 3 from rotating relatively, the hook 26 can be made by bending a lath-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 22;

in the structure of the weight-counting suspension support assembly 4, the suspension part 3 cannot rotate relative to the placing plate 12, so that stable support can be provided for the drainage bag 22, and the phenomenon that the weight counting is not accurate due to the rotation or shaking of the drainage bag 22 in the drainage process is avoided; the hanging part 3 and the weighing rod 25 can transmit the weight change of the effusion in the drainage bag 22 to the weighing sensor 15; the hanging part 3 can be adjusted in position in the vertical direction so as to adjust the height of the drainage bag 22; 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. 6 and 7, when the intelligent medical clinical drainage control device is used clinically, in the negative pressure drainage process, the drainage tube 21 deforms through the self elastic capacity to provide necessary pressure for negative pressure drainage, generally speaking, the drainage tube 21 used clinically at present has better elasticity, and in the initial stage of negative pressure drainage, the elastic performance of the drainage tube 21 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 21 positioned in the tube placing gap is weakened, and the maximum negative pressure which can be provided by the self elastic capacity is reduced; however, in the use process of the intelligent medical clinical drainage control device, the intelligent medical clinical drainage control device can be placed at a position lower than a patient, in addition, the drainage adjusting component acts on the middle lower part of the drainage tube 21, the gravitational potential energy of effusion in the drainage tube 21 can relieve the requirement of required negative pressure, the negative pressure which needs to be additionally provided under the condition is smaller, and even if the elasticity of the drainage tube 21 in the tube placing gap is weakened, enough negative pressure can still be provided for negative pressure drainage.

Referring to fig. 9 and 10, in the clinical use of the intelligent medical clinical drainage control device, the weight of the drainage bag 22 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 22 and the effusion inside the drainage bag is finally transmitted to the weighing sensor 15, the weights of the hanging part 3 and the installed drainage bag 22 are constant and unchangeable in the drainage process, so that the weight change sensed by the weighing sensor 15 is all caused by the increase of the effusion in the drainage bag 22, so that the controller can calculate the weight of the effusion actually drained in unit time, that is, the real-time drainage speed according to the weight signal continuously fed back by the weighing sensor 15 in real time in the drainage process, and can calculate the accumulated weight increase of the effusion in the drainage bag 22 from the beginning of the drainage to the present period, that is, the single real-time drainage quantity, 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 15 in real time can be realized by adopting the prior art;

based on the working principle adopted by the intelligent medical clinical drainage control device, the output of two adjacent hydrops has a certain time interval in the drainage process, namely the hydrops 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 unit time is preferably a time period which can at least complete the output of two fluids; 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 21.

Referring to fig. 9 and 10, when the intelligent medical clinical drainage control device is used clinically, the drainage bag 22 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 22, the acting force may change along with the deformation of the drainage bag 22, and the force and the change of the force are inevitably picked up by the weighing sensor 15 and fed back to the 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 medical clinical drainage control device, before clinical drainage is implemented, the height of the drainage bag 22 can be adjusted through the hanging part 3, so that the part of the drainage tube 21, which is positioned between the lead-out groove 5 and the drainage bag 22, is in a natural extension state, the acting force of the lower end of the drainage tube 21 on the drainage bag 22 can be reduced, and the acting force between the drainage tube 21 and the drainage bag 22 tends to be constant, thereby reducing the influence of the factors on the data accuracy of real-time drainage speed and single real-time drainage quantity to the maximum extent.

Referring to fig. 2, 9 and 10, in the above-mentioned intelligent medical clinical drainage control device, the weighing sensor 15 can pick up the change state of the weight of the accumulated liquid in the drainage bag 22, 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 15 is a key factor that affects whether the intelligent medical clinical drainage control 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, 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 15 can be ensured only when the intelligent medical clinical drainage control device is horizontally placed, otherwise, the gravity generated by accumulated liquid in the drainage bag 22 is decomposed, and the weight signal output by the weighing sensor 15 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 medical clinical drainage control 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 15 can be ensured to be relatively accurate;

step back, even if the ground in the ward can not reach the requirement of tending to the horizontality, the ground can be adjusted by a mode of arranging articles below the base 1 in a cushioning mode, so that the intelligent medical clinical drainage control device is horizontally arranged, and the accuracy of the weight signal output by the retransmission sensor in the clinical drainage process is ensured.

Referring to fig. 3 and 12, in the above-mentioned intelligent medical clinical drainage control device, the upper movable pressing block 8, the middle movable pressing block 7 and the lower movable pressing block 6 can respectively move in a linear stroke to move away from and close to the fixed pressing block 10, and the pushing plate 16 can move in a linear stroke to push the upper movable pressing block 8, the middle movable pressing block 7 and the lower movable pressing block 6; in terms of the prior art, the above technical features have various embodiments, for example, the above technical features can be implemented based on the sliding blocks 31 and the sliding rails 27 which are in sliding fit, that is, one or more sliding blocks 31 are respectively arranged on the upper movable pressing block 8, the middle movable pressing block 7, the lower movable pressing block 6 and the push plate 16, and the slide rails 27 which limit and guide each sliding block 31 are arranged on the installation plate 12, so that the technical requirements of the above technical features can be met; in addition, the technical characteristics can also be implemented by adopting linear guide rail mechanisms commonly used in other mechanical fields;

in addition, as shown in fig. 12, when the upper movable pressing block 8, the middle movable pressing block 7, and the lower movable pressing block 6 are engaged with the installation plate 12 through the structures of the sliding block 31 and the sliding rail 27, the ejector springs 19 for respectively driving the upper movable pressing block 8, the middle movable pressing block 7, and the lower movable pressing block 6 to be reset to the respective stroke starting ends may be installed in the corresponding sliding block 31 and the corresponding sliding rail 27, thereby facilitating to make the engaging structure of the upper movable pressing block 8, the middle movable pressing block 7, and the lower movable pressing block 6 with the installation plate 12 more compact.

Referring to fig. 5 and 6, in the above-mentioned intelligent medical clinical drainage control device, a telescopic ejector rod 18 is installed on the push plate 16, when the push plate 16 is located at the stroke start end, the telescopic ejector rod 18 does not provide an ejection function for the upper movable pressure block 8, when the push plate 16 moves from the stroke start end to the stroke end, at the stroke front section, the telescopic ejector rod 18 is in an extended state and can firstly eject the upper movable pressure block 8 to the stroke end, at the stroke middle section and the stroke rear section, the telescopic ejector rod 18 is passively compressed by the telescopic characteristic of the telescopic ejector rod 18, on one hand, the upper movable pressure block 8 maintains the stroke end, on the other hand, the push plate 16 can continuously move to eject the middle movable pressure block 7 and the lower movable pressure block 6, and finally, the drainage regulating assembly prompts the drainage tube 21 to complete fluid output;

as shown in fig. 13, based on the above functions of the telescopic ejector 18, it can be implemented by using the existing inserting and extending structure, that is, the telescopic ejector 18 includes a sleeve 34 and an ejector 32 that are inserted and matched to extend, the sleeve 34 is fixed on the push plate 16 and moves synchronously with the push plate 16, the ejector 32 is used for pushing the movable press block 8 to move towards the stroke terminal direction, and a telescopic spring 33 that drives the telescopic ejector 18 to automatically return to the extended state is arranged in the sleeve 34, when the intelligent medical clinical drainage control device is manufactured, the specific size and parameters of each component in the telescopic ejector 18 and the relative installation position of the telescopic ejector 18 and the push plate 16 are reasonably adjusted, so that the telescopic ejector 18 has the above functions without difficulty.

Referring to fig. 3 and 10, in the above intelligent medical clinical drainage control device, the electric feeding mechanism 17 is used for driving the push plate 16 to move, and the controller can adjust the position of the push plate 16 based on the control of the working state of the electric feeding mechanism 17; in the prior art, the above technical features are easy to implement and have various embodiments, but in order to make the structure of the electric feeding mechanism 17 compact, it is preferable to implement the following structure:

as shown in fig. 12, the electric feeding mechanism 17 includes a servo motor 28 fixed on the setting plate 12 and a screw mechanism composed of a screw 29 and a screw sleeve 30; the screw 29 is driven by the servo motor 28 to rotate, the threaded sleeve 30 is fixedly connected with the push plate 16, and when the servo motor 28 drives the screw 29 to rotate, the threaded sleeve 30 drives the push plate 16 to move in a linear stroke; the start-stop, the rotation direction and the rotation angle of the operation of the servo motor 28 are controlled by a controller; the above-mentioned electric feeding mechanism 17 achieves the required feeding requirement based on the cooperation of the servo motor 28 and the screw mechanism, and in addition, the specific structure of the electric feeding mechanism 17 can be implemented by those skilled in the art based on the cooperation of the servo motor 28 and the conventional mechanism such as a crank link mechanism, a cam mechanism, a rack and pinion mechanism, etc., and the technical requirements for the electric feeding mechanism 17 in the present embodiment can be achieved.

Referring to fig. 3, in the above intelligent medical clinical drainage control device, a locking mechanism 20 is disposed on the placement plate 12, and when the lower movable pressing block 6 moves to the stroke end, the locking mechanism 20 can automatically lock the lower movable pressing block 6, so that the lower movable pressing block 6 stays at the stroke end; as shown in fig. 7, during the fluid suction, while the push plate 16 moves toward the stroke start end, the push plate 16 does not cause the locking mechanism 20 to release the locking action on the lower active pressure block 6, that is, the lower active pressure block 6 is always at the stroke end, and the lower end of the internal draft tube 21 in the tube placement gap is kept in the blocked state; as shown in fig. 6, when the push plate 16 moves toward the stroke end and passes through the middle of the stroke during fluid delivery, the push plate 16 causes the locking mechanism 20 to release the locking action on the lower movable pressure block 6, so that the lower movable pressure block 6 is reset toward the stroke start end to bring the lower end of the tube placing gap internal drainage tube 21 into a conducting state;

based on the above functions of the locking mechanism 20, the locking mechanism 20 may be implemented based on a combination of a positioning mechanism and a one-way driving mechanism, for example, the locking mechanism 20 may be implemented based on a positioning mechanism and a one-way driving mechanism, which are commonly used, when the lower movable pressing block 6 is located at the stroke end, the positioning mechanism performs positioning, when the pushing plate 16 moves towards the stroke end, the one-way driving mechanism provides sufficient driving force for the positioning mechanism, so that the positioning mechanism releases the locking effect on the lower movable pressing block 6, when the pushing plate 16 moves towards the stroke start end, the one-way driving mechanism does not provide driving force for the positioning mechanism, and the positioning mechanism maintains the locking effect on the lower movable pressing block 6;

meanwhile, the embodiment of the locking mechanism 20 having the advantages of compact structure, good stability, etc. is also provided in the present embodiment, and the specific structure is as follows:

as shown in fig. 14 and 15, the locking mechanism 20 includes a locking pin 38 and an unlocking mechanism; the locking pin 38 is limited in a pin seat 39 arranged on the setting plate 12 and can float, a thrust spring 40 which is propped against the inner end of the locking pin 38 is arranged in the pin seat 39, and when only the lower movable pressing block 6 moves to the stroke end, the upper end of the locking pin 38 extends out of the pin seat 39 to block the lower movable pressing block 6 from moving towards the stroke initial end; the unlocking mechanism comprises a central wheel 35, a ring gear 36 and a rack part 37, the central wheel 35 is rotationally fixed on the placing plate 12 through a wheel shaft, the central wheel 35 is connected with a locking pin 38 through a crank arm 41, the ring gear 36 is sleeved outside the central wheel 35, and the central wheel 35 and the ring gear are matched through a ratchet mechanism; rack portion 37 is provided on push plate 16, and rack portion 37 meshes with ring gear 36 at and only when push plate 16 passes through the middle of the stroke; when the push plate 16 moves towards the stroke terminal direction and passes through the stroke middle section, the ring gear 36 drives the central wheel 35 to synchronously rotate, and the central wheel 35 drives the locking pin 38 to retract into the pin seat 39 through the crank arm 41; when the push plate 16 moves in the stroke start direction and passes through the middle of the stroke, the ring gear 36 does not rotate the center wheel 35.

Referring to fig. 9, the intelligent medical clinical drainage control 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 aim of full-automatic drainage control is fulfilled, the labor burden is saved, and the safety, stability and accuracy of drainage operation are improved; the intelligent medical clinical drainage control device is matched with the conventional drainage bag 22 and the drainage tube 21 for use, and the existing structures of the drainage bag 22 and the drainage tube 21 are not required to be changed, so that the intelligent medical clinical drainage control device is easier to popularize and use; the intelligent medical clinical drainage control 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 clinical drainage control device has the advantages of small volume, convenient movement, convenient carrying, small occupied space, high flexibility and great clinical popularization value.

Example 2

Referring to fig. 2 and 9, in the intelligent medical clinical drainage control device disclosed in embodiment 1, it has been clarified that the accuracy of the weighing signal output by the weighing sensor 15 is greatly influenced by whether the intelligent medical clinical drainage control device is horizontally placed; if meet ground levelness when relatively poor although the accessible fills up the mode of establishing article and solve below base 1, 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 medical clinical drainage control device of intelligence that the embodiment disclosed:

as shown in fig. 16 and 17, a first rotating shaft 44 extending horizontally and backwardly is fixed at the rear side of the installation plate 12, and a swinging seat 43 is fixed through the first rotating shaft 44 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 swinging seat 43 through the second rotating shaft 42, so that the weight-measuring suspension support assembly 4 can swing back and forth in a small range; the first rotating shaft 44 and the second rotating shaft 42 are perpendicular to each other; when the drainage bag 22 is fixed by the hanging part 3, the weight-measuring type suspension support assembly 4 is driven by gravity to always maintain a specific direction, and the weight change state of the accumulated liquid in the drainage bag 22 can be accurately picked up by the weight sensor 15 in the specific direction;

after the intelligent medical clinical drainage control device is improved in structure, the weight-measuring suspension support assembly 4 has an automatic direction adjusting mechanism, and even if the intelligent medical clinical drainage control device is not horizontally arranged in clinical use, the weight-measuring suspension support assembly 4 can be automatically adjusted to and maintained in a specific direction through left-right swinging and front-back swinging, so that the weighing sensor 15 can work stably and accurately;

in the improved structure, the swinging seat 43 can swing left and right with small amplitude, the weight-measuring suspension component 4 can swing front and back with small amplitude, and the front and back swing and the left and right swing are both small amplitude, which is intended to limit the change of the relative position of the mounting plate 12 and the weight-measuring suspension component 4 within a small range, and avoid the inconvenience for the mounting, carrying and other operations of the intelligent medical clinical drainage control device caused by the unstable relative position of the mounting plate 12 and the weight-measuring suspension component 4; the specific swing angle range of the small amplitude has no accurate requirement, and the aim is to ensure that the intelligent medical clinical drainage control device can stably and accurately work under most ground conditions;

meanwhile, the technical requirements that the weight-measuring suspension assembly 4 and the swinging seat 43 can only swing back and forth and left and right within a small amplitude range are met, and the technical requirements can be easily met by arranging corresponding angle limiting mechanisms 45 between the weight-measuring suspension assembly 4 and the swinging seat 43 and between the swinging seat 43 and the mounting plate 12;

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 medical clinical drainage control 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 22, so that the technical requirement is realized without difficulty; the specific direction is that the gravity generated by the accumulated liquid in the drainage bag 22 tends to be totally fed back to the weighing sensor 15 when the weight-measuring type suspension support assembly 4 is in the direction, so that the weighing sensor 15 can accurately pick up the weight change state of the accumulated liquid in the drainage bag 22.

Example 3

Referring to fig. 9, drainage is a medical means commonly used in clinical practice at present, the clinical drainage process is mostly performed in a ward, and the intelligent medical clinical drainage control device needs to be frequently moved back and forth between wards and instrument rooms; when the intelligent medical clinical drainage control device is used clinically, the whole device can be stably supported by the base 1, the base 1 is necessarily large and heavy, the intelligent medical clinical drainage control device is difficult to move integrally and is influenced by the base 1, the intelligent medical clinical drainage control device is large in overall size, 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 medical clinical drainage control device can remove the heavy base 1 part and can be used by being matched with the infusion support, 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:

as shown in fig. 18 and 19, the intelligent medical clinical drainage control device further comprises a clamping member 47 which can be clamped and fixed on the infusion rod 51 of the infusion support; a combined seat 50 is arranged at the rear side of the placing plate 12, and the combined seat 50 is connected with the upper end of the upright post 2 in a detachable way; an assembling mechanism is arranged between the clamping piece 47 and the combined seat 50, and when the clamping piece 47 is connected with the combined seat 50, the intelligent medical clinical drainage control device can be supported by the infusion rod 51 to work; the combined seat 50 and the upright post 2 can adopt a splicing structure to realize the technical purpose of disassembly and assembly, and the disassembly and assembly operation is also convenient;

from this one, in clinical use, the medical clinical drainage controlling means of intelligence 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 the removal of the medical clinical drainage controlling means of intelligence is more convenient, uses more in a flexible way, and the operation is more convenient.
