C. in the drainage process, the controller calculates the single real-time drainage quantity from the initial point of the drainage to the current point in real time, when the single real-time drainage quantity reaches the preset single drainage quantity, the controller adjusts the positions of the upper movable pressing block 11, the middle movable pressing block 10 and the lower movable pressing block 7, so that the upper movable pressing block 11 and the lower movable pressing block 7 respectively extrude the two elastic branch pipes 14 to a blocking state, the middle movable pressing block 10 is positioned at the initial position, the drainage is finished at the moment, and the two elastic branch pipes 14 are respectively extruded by the upper movable pressing block 11 and the lower movable pressing block 7 to keep the blocking state at the moment, so that the quantitative drainage is realized;

in the negative pressure drainage mode, after the drainage, the controller adjusts well activity briquetting 10 to initial position, the intention of this technical characteristic lies in, when the negative pressure drainage pauses or finishes, rely on upper movable briquetting 11 and lower activity briquetting 7 to extrude two elastic branch pipes 14 respectively to the state of blocking, avoid the hydrops backward flow in drainage tube 21, and well activity briquetting 10 does not constitute the extrusion to drainage tube 21 for the pipe section that elastic branch pipe 14 in putting the pipe clearance and well activity briquetting 10 correspond can automatic recovery to the original state be cylindricly, avoid being in for a long time flattening state and elasticity reduces by a wide margin, guarantee the stable of follow-up negative pressure drainage and go on.

Referring to fig. 5-8 and 11, when the medical intelligent drainage control device is used clinically, in the negative pressure drainage process, the drainage adjusting assembly is controlled by the controller to enable the upper movable pressing block 11, the middle movable pressing block 10 and the lower movable pressing block 7 to perform corresponding squeezing action on the two elastic branch pipes 14 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, the structure that upper movable pressing block 11, middle movable pressing block 10, lower movable pressing block 7 and each elastic branch pipe 14 constitute can be regarded as a displacement pump, and the 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 a fluid is sucked into an elastic branch pipe 14 for one time, the lower end of the elastic branch pipe 14 is pressed to a blocking state by a lower movable pressing block 7, neither an upper movable pressing block 11 nor a middle movable pressing block 10 presses the elastic branch pipe 14, as shown in fig. 5 and 7, under the regulation of a controller, the upper movable pressing block 11 firstly presses the upper end of the elastic branch pipe 14 to the blocking state, the lower movable pressing block 7 does not press the elastic branch pipe 14 any more, at the moment, the upper end of the elastic branch pipe 14 and a drainage tube 21 are in the blocking state, and the lower end is communicated with a drainage bag 20;

fluid intake:

after one elastic branch pipe 14 finishes one-time fluid output, the upper end of the elastic branch pipe 14 is extruded to a blocking state by the upper movable pressing block 11, the lower movable pressing block 7 does not extrude the elastic branch pipe 14, and meanwhile, the middle section of the elastic branch pipe 14 is extruded by the middle movable pressing block 10 to be in a flattened state; as shown in fig. 6 and 8, under the regulation of the controller, the upper movable pressing block 11 does not press the upper end of the elastic branch pipe 14 any more, and the lower movable pressing block 7 presses the lower end of the elastic branch pipe 14 to the blocking state, at this time, the upper end of the elastic branch pipe 14 is communicated with the drainage tube 21, and the lower end of the elastic branch pipe 14 maintains the blocking state with the drainage bag 20, when the pressing action of the middle movable pressing block 10 on the elastic branch pipe 14 is gradually weakened until the pressing action is not caused any more, the middle section of the elastic branch pipe 14, which is originally in the flattened state, will recover to a cylindrical shape by its own elasticity, and the elastic branch pipe 14 sucks the fluid in the drainage tube 21 in the deformation process, that is, so;

the realization of negative pressure drainage:

as shown in fig. 5-8, when the controller sequentially adjusts the upper movable pressing block 11 to the left end of the stroke, the lower movable pressing block 7 to the right end of the stroke, the middle movable pressing block 10 to the left end of the stroke, the upper movable pressing block 11 to the right end of the stroke, the lower movable pressing block 7 to the left end of the stroke, and the middle movable pressing block 10 to the right end of the stroke, the two elastic branch pipes 14 sequentially and respectively complete one-time fluid output, and one elastic branch pipe 14 performs fluid output while the other elastic branch pipe 14 performs fluid suction; when the drainage regulating assembly circularly works in the mode under the regulation and control of the controller, the two elastic branch pipes 14 are enabled to alternately and circularly output fluid, and when one elastic branch pipe 14 outputs the fluid, the other elastic branch pipe 14 sucks the fluid, so that the fluid in the drainage pipe continuously flows into the drainage bag through the connecting pipe, and 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 two elastic branch pipes 14 are respectively extruded to a blocking state by the upper movable pressing block 11 and the lower movable pressing block 7, the negative pressure drainage is suspended or ended; when the operating frequency of the fluid output of the two elastic branch pipes 14 is increased and the duration of the fluid output is shortened, the drainage speed can be increased, and otherwise, the drainage speed is reduced.

Referring to fig. 10 and 11, in the above medical intelligent drainage control device, the weight-measuring suspension support assembly 5 mainly has two functions, on one hand, the weight-measuring suspension support assembly 5 provides a stable support for the drainage bag 20, so that the drainage bag 20 is in a suspension shape and has a basic function of containing drainage effusion during drainage, and on the other hand, during drainage, the weighing sensor 19 in the weight-measuring suspension support assembly 5 can output a weight signal reflecting a change state of the effusion weight in the drainage bag 20, so as to provide basic data for data processing of the controller, and at the same time, the weight-measuring suspension support assembly 5 can also adjust the height of the drainage bag 20 within a certain range, so that after the drainage bag 20, the connecting pipe and the medical intelligent drainage control device are combined, a pipe section of the connecting pipe between the drainage tank 6 and the drainage bag 20 can be adjusted to a natural extension shape; in terms of the prior art, the weight-measuring suspension support assembly 5 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 assembly 5 more compact and more stable under the condition that it satisfies the above requirements, the weighing suspension assembly 5 is preferably implemented by adopting the following structure:

as shown in fig. 10 and 12, the weight-measuring suspension assembly 5 includes a sliding sleeve 23, a weighing rod 24, a load cell 19 and a suspension portion 4; the sliding sleeve 23 is fixed on the placing plate 17, 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 4 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 the drainage bag 20 is fixedly connected with the hanging part 4, the weighing sensor 19 can pick up the weight change state of the accumulated liquid in the drainage bag 20 and output a corresponding weight signal;

in addition, generally speaking, most of the drainage bags 20 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 4 can be provided with a hook 25 for matching with the hanging ring of the drainage bag 20, and in order to prevent the drainage bag 20 and the hanging part 4 from relative rotation, the hook 25 can be made by bending a lath-shaped material; meanwhile, the lower end of the hanging part 4 can also be provided with a clamping mechanism which can clamp and fix the upper end of the drainage bag 20;

in the structure of the weight-counting suspension support assembly 5, the suspension part 4 cannot rotate relative to the placing plate 17, so that stable support can be provided for the drainage bag 20, and the phenomenon that the weight counting is not accurate due to the rotation or shaking of the drainage bag 20 in the drainage process is avoided; the hanging part 4 and the weighing rod 24 can transmit the weight change of the effusion in the drainage bag 20 to the weighing sensor 19; the hanging part 4 can be adjusted in position in the vertical direction so as to adjust the height of the drainage bag 20; the structure meets the basic function requirement of the weight-measuring type suspension support assembly 5, and has the advantages of simple structure, accurate measurement, small size, compactness and easiness in implementation.

Referring to fig. 5-8, when the medical intelligent drainage control device is used clinically, in the negative pressure drainage process, the elastic capacity of the two elastic branch pipes 14 is deformed to provide necessary negative pressure for the negative pressure drainage, generally speaking, the two elastic branch pipes 14 are made of the existing medical material with better elastic performance, at the initial stage of the negative pressure drainage, the elastic performance of the two elastic branch pipes 14 is optimal to meet the requirement of the negative pressure in the negative pressure drainage, but as the number of times of extrusion is increased, the elastic performance of the elastic branch pipes 14 is weakened, and the maximum negative pressure which can be provided by the elastic capacity of the elastic branch pipes is reduced; however, in the use process of the medical intelligent drainage control device, the medical intelligent drainage control device can be placed at a position lower than a patient, in addition, the connecting pipe is arranged at the lower end of the drainage pipe, the drainage pipe 21 and the gravitational potential energy of accumulated liquid in the connecting pipe can relieve the requirement of required negative pressure in the drainage process, the additionally provided negative pressure is smaller in the situation, and even if the elasticity of the two elastic branch pipes 14 is weakened, enough negative pressure can be still provided for negative pressure drainage.

Referring to fig. 10 and 11, in the clinical use of the medical intelligent drainage control device, the weight of the drainage bag 20 and the effusion inside the drainage bag is almost borne by the hanging part 4, that is, almost the entire weight of the drainage bag 20 and the effusion inside the drainage bag is finally transmitted to the weighing sensor 19, the weights of the hanging part 4 and the drainage bag 20 after installation are constant and unchangeable in the drainage process, and therefore, the weight change sensed by the weighing sensor 19 is all caused by the increase of the effusion in the drainage bag 20, 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 19 in real time in the drainage process, and can calculate the accumulated weight increase of the effusion in the drainage bag 20 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 19 in real time can be realized by adopting the prior art;

based on the working principle adopted by the medical intelligent 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 real-time drainage speed is not too short, and each elastic branch pipe 14 can generate at least two fluid outputs in one unit time is better; in addition, although the accumulated liquid flows in a pulse manner in the drainage process, because the two elastic branch pipes 14 alternately output the fluid and one elastic branch pipe 14 outputs the fluid and the other elastic branch pipe 14 sucks the fluid, the time interval between two adjacent fluid outputs is greatly reduced, the pulse feeling in the negative pressure drainage process is greatly reduced, and discomfort can not be brought to a patient generally.

Referring to fig. 10, when the medical intelligent drainage control device is used clinically, the drainage bag 20 is fixedly connected with the output end 3 of the connecting pipe in the drainage process, the output end 3 of the connecting pipe inevitably generates a certain acting force on the drainage bag 20, and the acting force may change along with the deformation of the drainage bag 20, and the force and the change of the force are inevitably picked up by the weighing sensor 19 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 medical intelligent drainage control device, before clinical drainage is implemented, the height of the drainage bag 20 can be adjusted through the hanging part 4, so that the part of the connecting pipe between the leading-out groove 6 and the drainage bag 20 is in a natural extension state, the acting force of the lower end of the connecting pipe on the drainage bag 20 can be reduced, and the acting force between the connecting pipe and the drainage bag 20 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.

As shown in fig. 2, 10 and 11, in the above medical intelligent drainage control device, the weighing sensor 19 can pick up the change state of the weight of the accumulated liquid in the drainage bag 20, 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 medical intelligent drainage control device can accurately control the drainage process; the weight metering function part in the weight metering type suspension support assembly 5 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 medical intelligent drainage control device is horizontally placed, otherwise, the gravity generated by accumulated liquid in the drainage bag 20 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 smoother and tends to be horizontal, so when the medical 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 19 can be ensured to be more 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 medical intelligent 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 11, in the above medical intelligent drainage control device, three electric feeding mechanisms 9 are respectively connected to the upper movable pressing block 11, the middle movable pressing block 10 and the lower movable pressing block 7, and the controller can regulate and control the working states of the three electric feeding mechanisms 9, so as to adjust the positions of the upper movable pressing block 11, the middle movable pressing block 10 and the lower movable pressing block 7 within the respective movable strokes, and it is not difficult to implement the above technical features by using the prior art in the electromechanical field, and in this embodiment, the above technical features are implemented by using the following structures more preferentially:

as shown in fig. 13, the three electric feeding mechanisms 9 have the same structure, and each of the three electric feeding mechanisms is composed of a servo motor 27, a screw rod 28 coaxially connected with an output shaft of the servo motor 27, and a guide block 29 in threaded fit with the screw rod 28, the three servo motors 27 are supported by the mounting plate 17, the guide block 29 is installed in a guide groove 26 in the mounting plate 17, the three guide blocks 29 are respectively and fixedly connected with the upper movable pressing block 11, the middle movable pressing block 10, and the lower movable pressing block 7, and when the servo motor 27 drives the screw rod 28 to rotate, the screw rod 28 drives the guide block 29 to move along the guide groove 26, so as to adjust the positions of the upper movable pressing block 11, the middle movable pressing block 10, and the lower movable pressing block 7; the start, stop, rotation direction and rotation angle of the operation of the servo motor 27 are controlled by a controller;

in the implementation structure of the electric feeding mechanism 9, the required feeding requirement is realized based on the screw mechanism, and besides, the specific structure of the electric feeding mechanism 9 can be implemented based on the conventional mechanisms such as the crank-link mechanism, the cam mechanism, the rack and pinion mechanism, etc., and the corresponding feeding requirement can be realized.

The medical intelligent 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 the 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 the drainage operation are improved; the medical intelligent drainage control device is matched with the conventional drainage bag and the conventional 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 medical intelligent drainage control device is easier to popularize and use; the medical intelligent 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 medical intelligent drainage control 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. 2 and 10, in the medical intelligent drainage control device disclosed in embodiment 1, it has been clarified that the accuracy of the weighing signal output by the weighing sensor 19 is greatly influenced by whether the medical 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 medical intelligent drainage control device that the embodiment disclosed:

as shown in fig. 14 and 15, a first rotating shaft 32 extending horizontally and backwardly is fixed on the rear side of the installation plate 17, and a swinging seat 31 is fixed through the first rotating shaft 32 and can swing left and right with a small amplitude; the upper end of the weight-measuring suspension support assembly 5 is connected with the swing seat 31 through the second rotating shaft 30, so that the weight-measuring suspension support assembly 5 can swing back and forth in a small range; the first rotating shaft 32 and the second rotating shaft 30 are perpendicular to each other; when the drainage bag 20 is fixed by the hanging part 4, the weight-measuring type suspension support assembly 5 is driven by gravity to always maintain a specific direction, and the weight sensor 19 can accurately pick up the weight change state of the accumulated liquid in the drainage bag 20 in the specific direction;

when the medical intelligent drainage control device is improved in structure, the weight-measuring suspension support assembly 5 has an automatic direction adjusting mechanism, even if the medical intelligent drainage control device is not horizontally arranged in clinical use, the weight-measuring suspension support assembly 5 can automatically adjust to and maintain a specific direction through left-right swinging and front-back swinging, so that the weighing sensor 19 can work stably and accurately, and the weighing sensor 19 and the controller can realize data transmission based on a wireless or wired technology;

in the improved structure, the swing seat 31 can swing left and right with small amplitude, the weight-measuring suspension assembly 5 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 17 and the weight-measuring suspension assembly 5 within a small range, and avoid the inconvenience for the mounting, carrying and other operations of the medical intelligent drainage control device caused by the unstable relative position of the mounting plate 17 and the weight-measuring suspension assembly 5; the specific swing angle range of the small amplitude has no accurate requirement, and the aim is to ensure that the medical intelligent drainage control device can stably and accurately work under most ground conditions;

meanwhile, the technical requirements that the weight-measuring suspension assembly 5 and the swinging seat 31 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 33 between the weight-measuring suspension assembly 5 and the swinging seat 31 and between the swinging seat 31 and the mounting plate 17;

for the technical requirement that the weight-measuring type suspension support assembly 5 can be automatically adjusted to and maintained in a specific direction under the drive of gravity, when the medical intelligent drainage control device is manufactured, the specific structural form of the weight-measuring type suspension support assembly 5 is debugged, and a standard operation mode is set for the connection mode of the suspension part 4 and the drainage bag 20, so that the technical requirement is achieved without difficulty; the specific direction refers to that the gravity generated by the accumulated liquid in the drainage bag 20 tends to be totally fed back to the weighing sensor 19 under the condition that the weight-measuring type suspension support assembly 5 is in 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 20.

Example 3

Referring to fig. 10, drainage is a medical means commonly used in clinical practice at present, and clinical drainage is mostly performed in a ward, and the medical intelligent drainage control device needs to be frequently moved back and forth between wards and instrument rooms; when the medical 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 whole medical intelligent drainage control device is labor-consuming to move and is influenced by the base 1, the whole volume of the medical intelligent drainage control device is large, the occupied space is large when the medical intelligent drainage control device is used, and the flexibility is poor;

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 medical 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. 16 and 17, the intelligent medical drainage control device further includes a clamping member 35 that can be clamped and fixed on a transfusion rod 39 of the transfusion stand; a combined seat 38 is arranged at the rear side of the placing plate 17, and the combined seat 38 is connected with the upper end of the upright post 2 in a detachable way; an assembling mechanism is arranged between the clamping member 35 and the combined seat 38, and when the clamping member 35 is connected with the combined seat 38, the medical intelligent drainage control device can be supported by the infusion rod 39 to work; the combined seat 38 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;

therefore, as shown in fig. 17, in clinical use, the medical intelligent drainage control device can work in cooperation with an infusion support commonly provided in a ward without depending on the support provided by the base 1, so that the medical intelligent drainage control device is more convenient to move, more flexible to use and more convenient and faster to operate.

Referring to fig. 17, in the above improved structure, the fastening member 35 and the combination seat 38 can be connected by the assembling mechanism, which is used to ensure that the fastening member 35 can provide sufficient and stable support for the medical 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 35 is combined with the combination seat 38, the assembling mechanism preferably adopts the following design, and has a specific structure:

as shown in fig. 16 and 17, the assembling mechanism is composed of a T-shaped groove 37 disposed on one side of the combining seat 38 and a T-shaped rib 36 disposed on the clamping member 35, the T-shaped groove 37 extends vertically, the upper end is a blind end, the lower end is an open end, the T-shaped rib 36 and the T-shaped groove 37 can be combined, and the damping pad 34 for clamping the T-shaped groove 37 is disposed at the lower end of the T-shaped rib 36;

based on the above structure adopted by the assembling mechanism, the T-shaped rib 36 of the clamping member 35 is inserted into the T-shaped groove 37 of the combined base 38 from bottom to top, so that the assembling of the combined base 38 and the clamping member 35 is completed, otherwise, the combined base 38 and the clamping member 35 can be separated; when the T-shaped rib 36 and the T-shaped groove 37 are completely combined, the damping pad 34 will clamp the T-shaped groove 37 to lock the relative position of the T-shaped rib 36 and the T-shaped groove 37, thereby preventing the clamping member 35 from separating from the combination base 38.

Referring to fig. 17, in the improved structure, the clamping member 35 is used for clamping and matching with the infusion rod 39 to provide a stable support for the medical intelligent drainage control device, and as far as the prior art is concerned, the clamping member 35 has various embodiments, for example, a clamping mechanism for clamping the infusion rod 39 can be arranged on the clamping member 35, or a C-shaped clamp can be arranged on the clamping member 35, and meanwhile, fastening screws are additionally arranged on the clamping mechanism and the C-shaped clamp, and an anti-slip gasket is additionally arranged on a contact surface with the infusion rod 39, so as to improve the stability after the clamping member 35 and the infusion rod 39 are combined; although the clamping piece 35 can meet the basic technical requirement of providing support for the medical intelligent drainage control device by adopting the structure, the clamping piece has the defects of not simple structure, not beautiful appearance, troublesome use and the like; meanwhile, generally speaking, the types of infusion supports used by the same medical institution are mostly the same, that is, the diameters of the infusion rods 39 are the same, but no exception exists, and the implementation structure adopted by the clamping member 35 is difficult to be compatible with the infusion rods 39 with different sizes for use, and certain limitation is certainly formed in clinical use; therefore, the present embodiment also proposes a novel implementation manner for the clamping member 35, and the specific structure is as follows:

as shown in fig. 18 and 19, a clamping opening 46 for accommodating the transfusion rod 39 is formed in one side of the clamping member 35, two opposite side walls of the clamping opening 46 are respectively provided with a limiting seat 40, a floating holding block 41 is respectively arranged in the limiting seat 40, opposite end portions of the two floating holding blocks 41 are arc-shaped ends 45, end surfaces of the two arc-shaped ends 45 are both arc-shaped and are respectively fixed with an anti-skid rubber pad 42, and the two arc-shaped ends 45 are respectively used for holding two sides of the transfusion rod 39; the floating holding block 41 and the limiting seat 40 are matched through a guide mechanism formed by the sliding chute 43 and the sliding block 44, so that the floating holding block 41 has an oblique floating stroke, when the two floating holding blocks 41 move upwards along respective floating strokes simultaneously, the two arc-shaped ends 45 gradually approach and enter the clamping opening 46, and when the two floating holding blocks 41 move downwards along respective floating strokes simultaneously, the two arc-shaped ends 45 gradually leave and finally retract into the corresponding limiting seats 40; the two limiting seats 40 are respectively provided with a return spring 47 which drives the corresponding floating holding block 41 to return to the uppermost end of the floating stroke;

as shown in fig. 19, after the clamping member 35 adopts the above structure, the clamping port 46 of the clamping member 35 is clamped outside the infusion rod 39, the two floating clasping blocks 41 can clamp and clasp the infusion rod 39 from two opposite sides of the infusion rod 39, the weight of the medical intelligent drainage control device can generate a downward acting force on the clamping member 35, and the two floating clasping blocks 41 can respectively receive horizontal component forces to further clasp the infusion rod 39, in short, the larger the weight borne by the clamping member 35 is, the firmer the two floating clasping blocks 41 clasp the infusion rod 39, so that the relative movement between the clamping member 35 and the infusion rod 39 can be avoided, and the stability after the clamping member 35 and the infusion rod 39 are combined can be improved;

meanwhile, because the two floating holding blocks 41 have certain floating strokes, the distance between the two floating holding blocks can be automatically adjusted according to the different diameters of the transfusion rods 39, the applicability of the clamping piece 35 is improved to a certain extent, and the clamping piece can be matched with various transfusion rods 39 with different diameters for use.

Example 4

Referring to fig. 5-9, in the clinical drainage process, the medical intelligent drainage control device performs different types of extrusion on the upper movable pressing block 11, the middle movable pressing block 10 and the lower movable pressing block 7 to the two elastic branch pipes 14 in the pipe gap to realize the adjustment and control of the drainage state, so that the stable matching of the connecting pipe and the drainage adjusting component is a necessary condition for ensuring the stable operation of the medical intelligent drainage control device; in the medical intelligent drainage control device disclosed in the foregoing embodiment, in order to facilitate the connection pipe to be combined and separated with the drainage regulating assembly, the introduction groove 13, the extraction groove 6 and the front side of the pipe placing gap are all open, and there is a risk that the connection pipe slips from the front side of the corresponding pipe placing gap in the drainage process, thereby reducing the working stability of the medical intelligent drainage control device, and for solving the above problems, the embodiment has further improvement on the medical intelligent drainage control device:

as shown in fig. 20 and 21, a cover plate 49 is disposed on the front side of the placement plate 17, the inner end of the cover plate 49 is rotatably connected to the placement plate 17 through a rotating shaft 51, two pressing blocks 48 are disposed on one side wall of the cover plate 49, and the cover plate 49 has two station states and can be switched between the two station states by turning over; when the cover plate 49 is turned to a station state, the cover plate covers the pipe placing gap, the upper movable pressing block 11, the middle movable pressing block 10 and the front side of the lower movable pressing block 7, and the two pressing blocks 48 are respectively pressed into the lead-in groove 13 and the lead-out groove 6 to firmly clamp and fix the input end 12 and the output end 3 of the connecting pipe; when the cover plate 49 is turned to another station state, it covers the front sides of the display screen 15 and the setting keys 16; a locking mechanism 50 which can lock the cover plate 49 at two stations respectively is arranged between the cover plate 49 and the setting plate 17;

therefore, in the drainage process, as shown in fig. 20, the front side opening of the tube placing gap can be plugged by the cover plate 49, and the input end 12 and the output end 3 of the connecting tube are respectively pressed in the introducing groove 13 and the leading-out groove 6 by the two pressing blocks 48, so that the elastic branch tube 14 can be prevented from slipping or moving from the tube placing gap in the drainage process, the working stability of the medical intelligent drainage control device is improved, meanwhile, the cover plate 49 can also prevent external foreign matters from entering the tube placing gap in the drainage process, and the working accuracy of the medical intelligent drainage control device is improved; when drainage is not performed, as shown in fig. 21, a better protection effect can be provided for the display screen 15 and the setting keys 16 by means of the cover plate 49, so that damage to vulnerable electronic components such as the display screen 15 and the setting keys 16 in the moving and idling processes of the medical intelligent drainage control device is avoided.

Referring to fig. 20 and 21, in the above improved structure, a locking mechanism 50 is provided between the cover plate 49 and the setting plate 17, and the locking mechanism 50 is used for locking and maintaining the cover plate 49 in a two-station state, that is, when the cover plate 49 is in a one-station state, the relative position of the cover plate 49 and the setting plate 17 can be locked by the locking mechanism 50, so that the cover plate 49 is maintained in the station state, and the corresponding function is exerted; based on this, as for the prior art, the locking mechanism 50 has various embodiments to satisfy the basic functions expected for the locking mechanism, but if the locking mechanism is implemented by the prior art, the prior art has certain disadvantages, or the operation is not convenient enough, and the locking and unlocking are required to be performed manually, or the locking failure is easy to occur, or the mating member is complex, the service life is short, and so on, for this reason, a novel locking mechanism 50 is further provided in this embodiment, and its specific implementation structure is as follows:

as shown in fig. 22, the locking mechanism 50 includes a tongue piece 55 movably limited on the cover plate 49 and two locking magnetic sheets 52 installed on the installation plate 17, a strong magnet 54 is installed on the tongue piece 55, when the tongue piece 55 is in a reset state, the outer end is exposed outside the outer end of the cover plate 49, and a spring piece 53 for driving the tongue piece 55 to automatically reset is installed in the installation plate 17; when the tongue piece 55 is in a reset state and the cover plate 49 is in a one-station state, the strong magnet 54 is positioned right above the corresponding locking magnet piece 52, and at the moment, the relative positions of the cover plate 49 and the placing plate 17 are locked by the strong magnet 54 and the locking magnet piece 52 through adsorption force; when the cover plate 49 is in a working position state, the manual pushing tongue piece 55 moves inwards, so that the strong magnetic block 54 can be staggered with the corresponding locking magnetic sheet 52, the locking effect is relieved, and the cover plate 49 can be turned over;

after the locking mechanism 50 adopts the above structure and the cover plate 49 is adjusted to a station state, the strong magnet block 54 and the corresponding locking magnet piece 52 lock the cover plate 49 through a larger adsorption force, so that the cover plate 49 can play an expected function, although the strong magnet block 54 and the locking magnet piece 52 have a larger adsorption force when keeping the opposite direction, the shearing resistance is poorer, therefore, when the station of the cover plate 49 needs to be adjusted, the tongue piece 55 can be easily pushed to move inwards, and then the strong magnet block 54 and the corresponding locking magnet piece 52 are staggered, and the adsorption force between the two is greatly reduced, so that the cover plate 49 can be easily turned over to adjust the station state; the locking mechanism 50 has the advantages of ingenious structural design, stable work, easy implementation and no jamming fault, and overcomes the defects of the prior similar technology.

Example 5

Based on the working mechanism of the medical intelligent drainage control device disclosed by the embodiment, when negative pressure drainage is performed, effusion flows in a pulse mode, the flow rate is not uniform, and based on the characteristic, on one hand, the accuracy of data of real-time drainage speed obtained by calculation of a controller is influenced to a certain extent, and on the other hand, a patient may feel certain pulse feeling in the negative pressure drainage process; therefore, the structure of the connecting pipe is optimized and improved to a certain extent in the embodiment, the pulse feeling of effusion flowing in the negative pressure drainage process is reduced, and the adopted technical means are as follows:

as shown in fig. 23, the input end 12 of the connecting tube is communicated with the two elastic branch tubes 14 through the upper telescopic buffer bag 56, the output end 3 is communicated with the two elastic branch tubes 14 through the lower telescopic buffer bag 58, the upper telescopic buffer bag 56 and the lower telescopic buffer bag 58 are both made of elastic materials, and the outer walls are corrugated, so that the inner cavity pressure of the upper telescopic buffer bag 56 and the lower telescopic buffer bag 58 can be kept constant through telescopic deformation; the arrangement plate 17 is provided with two bag seats 57 which are distributed up and down, and the two bag seats 57 are respectively used for clamping and fixing the lower end of the upper telescopic buffer bag 56 and the upper end of the lower telescopic buffer bag 58;

therefore, in the negative pressure drainage process, when fluid is output by an elastic branch pipe 14, the output effusion firstly enters and is stored in the lower telescopic buffer bag 58, the lower telescopic buffer bag 58 automatically extends and retracts according to the internal pressure so as to ensure that the flow rate of the effusion flowing into the drainage bag tends to be uniform, and the accuracy of the data of the real-time drainage speed calculated and obtained by the controller is improved; when fluid is input into an elastic branch pipe 14, the fluid is sucked from the upper telescopic buffer bag 56, and the upper telescopic buffer bag 56 automatically stretches according to the internal pressure, so that the uniform negative pressure generated at the tail end of the drainage tube is ensured, the pulse feeling of the flowing of the fluid in the drainage tube is reduced, and the discomfort of a patient is avoided.
