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 the single real-time drainage volume reaches preset single drainage volume, the position of vertical briquetting 8 will be adjusted to the controller, make lower pars contractilis 6 will put the leading-out end extrusion of drainage tube 21 to the state of blocking in the tub clearance, guarantee simultaneously that pars contractilis 9 does not constitute the extrusion to the leading-in end of drainage tube 21 in putting the tub clearance, then adjust two horizontal briquettings 12 to initial position, this time drainage is ended and drainage tube 21 is pushed and is kept ending the state by lower pars contractilis 6 this moment, realize quantitative drainage promptly.

In a negative pressure drainage mode, after drainage is finished, the controller adjusts the position of the longitudinal pressing block 8, so that the lower telescopic part 6 extrudes the leading-out end of the drainage tube 21 to a blocking state, meanwhile, the upper telescopic part 9 is ensured not to extrude the leading-in end of the drainage tube 21, and then the two transverse pressing blocks 12 are adjusted to initial positions; the technical characteristics are that when the negative pressure drainage is suspended or finished, the leading-out end of the drainage tube 21 is extruded to a blocking state by the lower telescopic part 6 to avoid the backflow of accumulated liquid in the drainage tube 21, and the upper telescopic part 9 and the two transverse pressing blocks 12 do not extrude the drainage tube 21, so that the drainage tube 21 in the tube placing gap can be automatically restored to an original state, namely a cylindrical shape, the phenomenon that the drainage tube is in a flattened state for a long time and the elasticity is greatly reduced is avoided, and the follow-up negative pressure drainage can be stably carried out.

Referring to fig. 6, 7 and 9, when the intelligent drainage control device is used clinically, in the negative pressure drainage process, the drainage adjusting assembly under the control of the controller causes the longitudinal pressing block 8 and the two transverse pressing blocks 12 to perform corresponding squeezing action on the drainage tube 21 according to a specific rule, so that negative pressure drainage is realized and the negative pressure drainage state can be adjusted; 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 drainage tube 21 that put in the pipe clearance constitutes can be regarded as a displacement pump, and theory of operation is very similar with the diaphragm pump, 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:

when one-time negative pressure suction is finished, the longitudinal pressing block 8 is positioned at the lower end of the stroke, the lower telescopic part 6 extrudes the leading-out end of the drainage tube 21 to a blocking state, the upper telescopic part 9 does not extrude the leading-in end of the drainage tube 21, and the two transverse pressing blocks 12 are positioned at the initial position; as shown in fig. 6, when the controller adjusts the position of the longitudinal pressing block 8 to move the longitudinal pressing block 8 to the upper end of the stroke, the upper telescopic part 9 extrudes the leading-in end of the drainage tube 21 in the tube placing gap to a blocking state, the lower telescopic part 6 does not extrude the leading-out end of the drainage tube, at this time, the leading-out end of the drainage tube 21 in the tube placing gap is communicated with the drainage bag 22, when the two transverse pressing blocks 12 are far away, the drainage tube 21 in the tube placing gap is respectively extruded by the two transverse pressing blocks 12 to change the volume, and the internal effusion flows to the direction of the drainage bag 22, thereby realizing the fluid output; as shown in fig. 5, 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 to the blocking state, the leading end of the drainage tube 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 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 21 can be avoided, and the unidirectional output of the fluid can be realized;

fluid intake:

when the drainage regulating assembly prompts the drainage tube 21 to finish primary fluid output, the longitudinal pressing block 8 is positioned at the upper end of the stroke, at the moment, the upper telescopic part 9 extrudes the introduction end of the drainage tube 21 to a blocking state, the lower telescopic part 6 does not extrude the extraction end of the drainage tube 21, and the two transverse pressing blocks 12 are in a far state to flatten the drainage tube 21 between the introduction end and the extraction end; as shown in fig. 7, when the controller adjusts the position of the longitudinal pressing block 8, the lower telescopic part 6 presses the leading-out end of the drainage tube 21 in the tube placing gap to a blocking state, the upper telescopic part 9 does not press the leading-in end of the drainage tube, the leading-in end of the drainage tube in the tube placing gap is in a conducting state and is communicated with the human body, after the two transverse pressing blocks 12 approach and reset to the initial position, the drainage tube 21 which is originally positioned between the leading-out end and the leading-in end and is squashed by the two transverse pressing blocks 12 can gradually restore to a cylindrical shape by virtue of the elasticity of the drainage tube, and the front end of the drainage tube 21 generates negative pressure along with the increase of the volume, so that effusion in the human body is sucked into the drainage tube 21, namely;

the realization of negative pressure drainage:

when the drainage adjusting component causes the drainage tube 21 to alternately output fluid and suck the fluid, the fluid in the drainage tube 21 can be ensured to flow towards the drainage bag all the time, namely, the 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 leading-out end of the drainage tube 21 in the tube placing gap 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. 2, 9 and 10, in the above-mentioned intelligent 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, so that the drainage bag 22 is in a suspension shape and has a basic function of containing drainage effusion in the drainage process, on the other hand, in the drainage process, the weighing sensor 20 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 22, so as to provide basic data for data processing of the controller, and at the same time, 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 drainage control device are combined, the part of the drainage tube 21 between the drainage groove 5 and the drainage bag 22 can be adjusted to 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 24, a weighing rod 25, a load cell 20 and a suspension portion 3; the sliding sleeve 24 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 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 20 is fixed in the sliding sleeve 24 to provide 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 20 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 mounting plate 15, 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 20; 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 drainage control device is used clinically, in the negative pressure drainage process, the drainage tube 21 deforms through the elastic capacity of the drainage tube 21 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 increases, the elastic performance of the drainage tube 21 in the tube placing gap is weakened, and the maximum negative pressure which can be provided by the elastic capacity of the drainage tube is reduced; but in this intelligence drainage control device use, it can place in the position that is less than the patient, and drainage adjusting part acts on the well lower part of drainage tube 21 in addition, and the required negative pressure requirement can be alleviated to the gravitational potential energy of hydrops in drainage tube 21 in the drainage process, and the negative pressure that needs additionally provide under this condition is less, even the drainage tube 21 elasticity that is located to put the intraductal clearance weakens, still can provide sufficient negative pressure for the negative pressure drainage.

Referring to fig. 9, 10 and 11, in the clinical use of the intelligent 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 20 through the hanging part 3, 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 20 is all caused by the increase of the effusion in the drainage bag 22, therefore, 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 22 during the period from the beginning of the drainage to the present, 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 20 in real time can be realized by adopting the prior art;

based on the working principle adopted by the intelligent drainage control device, the output of two adjacent accumulated liquids in the drainage process has a certain time interval, namely the accumulated liquids flow 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 be capable of generating 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 21.

Referring to fig. 9, 10 and 11, when the intelligent 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 20 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 drainage control device, before clinical drainage is implemented, the height of the drainage bag 22 can be adjusted through the weight-measuring type suspension support assembly 4, so that the part of the drainage tube 21, which is positioned between the drainage 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. 9, 10 and 11, in the above-mentioned intelligent drainage control device, the weighing sensor 20 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 20 is a key factor that affects whether the intelligent 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, 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 20 can be ensured only when the intelligent drainage control device is horizontally arranged, otherwise, the gravity generated by accumulated liquid in the drainage bag 22 is decomposed, so that the weight signal output by the weighing sensor 20 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 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 20 can be ensured to be relatively accurate;

step back, even if ground in the ward can not reach the requirement of tending to the horizontality, the mode that the article are set up to the pad below the base 1 is adjusted to make the intelligent drainage control device be horizontal placement, and the accuracy of the weight signal output by the retransmission sensor in the clinical drainage process is guaranteed.

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 28 extending up and down, the upper telescopic part 9 and the lower telescopic part 6 are respectively composed of a guide post 32 and a jacking part 33 fixedly connected, the two jacking parts 33 are respectively used for extruding the drainage tube in the gap between the two placed tubes, the two guide posts 32 are respectively in sliding fit with the two guide holes 28, the guide posts 32 and the corresponding guide holes 28 can only move relatively in the axial direction and cannot be separated, the inner ends of the two guide posts 32 are respectively provided with a blind hole-shaped post cavity 31, and a jacking spring 29 is arranged between the bottom of the post cavity 31 and the bottom of the corresponding guide hole 28, so that the upper telescopic part 9 and the lower telescopic part 6 can be stretched and retracted relative to the longitudinal pressing block 8 and can be 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 posts 32 respectively abut against the bottoms of the two guide holes 28, and the two jacking parts 33 respectively abut against the upper end and the lower end of the longitudinal pressing block 8; two positioning pins 27 capable of manually adjusting the axial position are arranged on the longitudinal pressing block 8, and two positioning holes 30 are respectively arranged on the two guide columns 32; the axial position of the positioning pin 27 is manually adjusted, so that the positioning pin 27 does not form a barrier to the relative movement of the guide post 32 and the guide hole 28; when the upper telescopic part 9 and the lower telescopic part 6 are in a contracted state, the axial position of the positioning pin 27 is manually adjusted, so that the positioning pin 27 is matched with the corresponding positioning hole 30, and the relative positions of the guide post 32 and the guide hole 28 are locked.

Example 2

Referring to fig. 9 and 11, in the intelligent drainage control device disclosed in embodiment 1, it has been clarified that the accuracy of the weighing signal output by the weighing sensor 20 is greatly affected by whether the intelligent drainage control device is horizontally placed; although the mode of establishing article through the pad below base 1 when meeting ground levelness relatively poor solves, nevertheless the operation is got up comparatively trouble, wastes time and energy, and for this reason, this embodiment still has following improvement on the structure basis of the intelligent drainage controlling means that the embodiment disclosed:

as shown in fig. 16 and 17, a first rotating shaft 46 extending horizontally and backwardly is fixed at the rear side of the installation plate 15, and a swinging seat 45 is fixed through the first rotating shaft 46 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 45 through the second rotating shaft 44, so that the weight-measuring suspension support assembly 4 can swing back and forth in a small range; the first rotating shaft 46 and the second rotating shaft 44 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 20 in the specific direction;

after the intelligent drainage control device is improved in structure, the weight-measuring suspension support assembly 4 has an automatic direction adjusting mechanism, even if the intelligent drainage control device is not horizontally arranged in clinical use, the weight-measuring suspension support assembly 4 can automatically adjust to and maintain a specific direction through left-right swinging and front-back swinging, so that the weighing sensor 20 can stably and accurately work; the weighing sensor 20 can realize data transmission through a circuit and a controller, and can also realize data transmission between the weighing sensor and the controller through a wireless transmission technology;

in the improved structure, the swing seat 45 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 operation of mounting, carrying and the like of the intelligent drainage control 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 aim is to ensure that the intelligent 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 45 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 47 between the weight-measuring suspension assembly 4 and the swinging seat 45 and between the swinging seat 45 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 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 achieved 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 20 when the weight-measuring type suspension support assembly 4 is in the direction, so that the weighing sensor 20 can accurately pick up the weight change state of the accumulated liquid in the drainage bag 22.

Example 3

Referring to fig. 1 and 10, drainage is a medical means which is commonly used in clinical practice at present, the clinical drainage process is mostly performed in a ward, and the intelligent drainage control device needs to be frequently moved back and forth between wards and instrument rooms; when the intelligent drainage control device is clinically used, the whole device can be stably supported by the base 1, the base 1 is necessarily large and heavy, the intelligent drainage control device is difficult to move integrally and is influenced by the base 1, the intelligent drainage control device is large in overall size, large in occupied space when in 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 drainage control device can remove the heavy base 1 part and can be used together 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 drainage control device further includes a clamping member 49 capable of being clamped and fixed on the infusion rod 53 of the infusion support; a combined seat 52 is arranged at the rear side of the placing plate 15, and the combined seat 52 is connected with the upper end of the upright post 2 in a detachable way; an assembling mechanism is arranged between the clamping member 49 and the combined seat 52, and when the clamping member 49 is connected with the combined seat 52, the intelligent drainage control device can be supported by the transfusion rod 53 to work; the combined seat 52 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, intelligence drainage controlling means 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 drainage controlling means'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 49 and the combination seat 52 can be connected by means of the assembling mechanism, in order to ensure that the fastening member 49 can provide sufficient and stable support for the intelligent drainage control device, as for the prior art, the assembling mechanism has various embodiments, but in order to ensure the stability and the convenience of disassembling and assembling after the fastening member 49 and the combination seat 52 are combined, the assembling mechanism preferably adopts the following design, and the specific structure is as follows:

as shown in fig. 18 and 19, the assembling mechanism comprises a T-shaped groove 51 disposed on one side of the combination seat 52 and a T-shaped rib 50 disposed on the clamping member 49, the T-shaped groove 51 extends vertically, the upper end is a blind end, the lower end is an open end, the T-shaped rib 50 and the T-shaped groove 51 can be combined, and a damping pad 48 for clamping the T-shaped groove 51 is disposed at the lower end of the T-shaped rib 50;

based on the above structure adopted by the assembly mechanism, the T-shaped rib 50 of the clamping member 49 is inserted into the T-shaped groove 51 of the combined base 52 from bottom to top, so that the assembly of the combined base 52 and the clamping member 49 is completed, otherwise, the combined base 52 and the clamping member 49 can be separated; when the T-shaped rib 50 and the T-shaped groove 51 are completely combined, the damping pad 48 tightly clamps the T-shaped groove 51 to lock the relative position of the T-shaped rib 50 and the T-shaped groove 51, thereby preventing the clamping member 49 from being separated from the combination base 52.
