Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a drainage nursing device for nursing. Background Art

[0002] A drainage care device refers to a device that can drain fluids (such as blood, exudate, pus, etc.) and gases (such as gas accumulation in the chest cavity) accumulated between human tissues or in body cavities out of the body, effectively reducing local pressure and preventing fluid or gas accumulation from causing infection, compressing surrounding tissues and organs, and other adverse conditions; at the same time, by observing the color, properties and amount of the drainage fluid, it can also provide important basis for medical staff to judge changes in the disease and evaluate the treatment effect, help to adjust the treatment plan in time, and promote patient recovery. For example, a detachable mobile intelligent drainage statistics device is disclosed in a Chinese patent with publication number CN117414482A.

[0003] In the process of draining liquid or gas from the human body by the existing drainage care device, the volume of the device itself is too large and the suction force generated by the device is generally maintained unchanged, so that when the patient moves at a low frequency (such as turning over, eating, playing with mobile phones, etc.), the position of the drainage tube in the body cavity may change. Due to the constant suction force, the head of the drainage tube is prone to abnormal traction or adsorption on the surrounding tissues, causing the drainage tube to deviate from the correct drainage position, thereby causing secondary damage to the patient;

[0004] When patients move frequently (such as going to the toilet, physical examination, etc.), the existing equipment is too large, which severely restricts the patient's movement, affecting the smooth excretion and examination; it increases the risk of drainage tube damage, leading to drainage failure, fluid leakage and infection.

[0025] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0026] 1. Through the magnetic variable component, hydraulic pressure, magnetic resistance component and flow absorber in the main drainage nursing mechanism, it is possible to provide corresponding suction according to the movement frequency of the patient transmitted by the secondary drainage nursing mechanism, wherein the controller enables the magnetic variable component to generate magnetic forces of different strengths according to the change of the patient's movement frequency, thereby repelling the opposite magnetic force in the magnetic resistance component. The stronger the opposite magnetic force generated by the magnetic variable component, the stronger the repulsion between the magnetic variable component and the magnetic resistance component. However, since the magnetic variable component is connected to the telescopic end of the hydraulic pressure, and the hydraulic pressure provides power to the flow absorber through the up and down movement of the telescopic end, the flow absorber generates suction to complete the flow suction. However, as the magnetic force of the magnetic variable component increases, the power and frequency provided by the hydraulic pressure to the flow absorber are also lower, thereby achieving the purpose of controlling the drainage suction. The suction can be adjusted according to the different movement states of the patient to ensure the stability and reliability of the drainage effect, improve the safety and effectiveness of the drainage, and reduce the risks of infection caused by improper drainage.

[0027] 2. Through the flow stabilizing component, flow adjusting component, amplitude detection component and suction bucket in the secondary drainage nursing mechanism, the patient's movement frequency can be detected and the suction input into the patient's body can be stabilized when the suction of the main drainage nursing mechanism changes, so as to prevent the increase or decrease of suction from causing discomfort to the human body. Among them, the flow stabilizing component can prevent the sudden increase or decrease of suction, which may lead to airflow backflow and airflow interruption, and the flow adjusting component can avoid airflow pressure imbalance. The amplitude detection component can detect the frequency of one end of the patient when using the main drainage nursing mechanism for drainage, and the suction bucket can realize the airflow suction exchange between the main drainage nursing mechanism and the liquid storage mechanism, and control the suction of the subsequent liquid storage mechanism, so as to prevent airflow backflow and interruption caused by sudden change of suction, avoid airflow pressure imbalance, ensure stable suction input into the patient's body, and prevent discomfort to the human body caused by sudden suction.

[0028] 3. Through the auxiliary liquid storage tank and the lever-type presser in the liquid storage mechanism, when the patient needs to move at a high frequency (such as going to the toilet, physical examination, etc.), when the auxiliary drainage nursing mechanism is separated from the main drainage nursing mechanism, the compressed auxiliary liquid storage tank in the auxiliary drainage nursing mechanism can provide short-term suction. When the auxiliary drainage nursing mechanism is connected to the main drainage nursing mechanism, the main drainage nursing mechanism can discharge the liquid absorbed in the auxiliary liquid storage tank through the suction bucket, so that the auxiliary liquid storage tank can be restored to a compressed state. When the patient moves at a high frequency and causes the auxiliary drainage nursing mechanism to be separated from the main drainage nursing mechanism, the compressed auxiliary liquid storage tank can provide short-term suction to ensure that the drainage process is not interrupted, maintain a good drainage effect, and avoid aggravation of problems such as fluid or gas accumulation due to lack of suction.

[0045] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0046] The present invention will be further described below in conjunction with the embodiments.

[0047] Example: Refer to Figures 1 to 14 , a drainage nursing device for nursing, comprising:

[0048] A base 1, a controller is installed on the side of the base 1;

[0049] The main drainage nursing mechanism 2 includes a shell 21 fixedly connected to the upper end surface of the base 1, and the upper end surface of the shell 21 is provided with a magnetic variable component 22 and a hydraulic device 23. The inside of the shell 21 is provided with a magnetic resistance component 24, a flow absorber 25 and a main liquid storage tank 26 in sequence from top to bottom;

[0050] The auxiliary drainage care mechanism 3 includes a shell 31 placed on the side of the base 1, and the inner bottom of the shell 31 is provided with a flow stabilizing component 32, a flow regulating component 33, a suction bucket 35 and two amplitude detection components 34. At least one vibrator 37 is fixedly connected to the inner bottom of the shell 31, and the vibrating surface of the vibrator 37 passes through the shell 31 and extends to the outside thereof, and the vibrator 37 is electrically connected to the data line 27;

[0051] The liquid storage mechanism 4 is arranged on the upper end surface of the shell 31 .

[0052] The changing magnetic force of the magnetic variable component 22 in the main drainage care mechanism 2 and the magnetic resistance component 24 generate repulsive forces of different strengths, which affects the frequency and speed of the reciprocating motion of the power provided by the hydraulic press 23 to the flow absorber 25. The flow absorber 25 is a negative pressure generated by the power passing through the hydraulic press 23, thereby generating suction. The auxiliary drainage care mechanism 3 is arranged on the surface of the patient's body, so as to detect the patient's movement frequency, and the auxiliary drainage care mechanism 3 provides two different drainage modes for the patient. Among them, the flow stabilizing component 32 and the flow adjusting component 33 are used to stabilize the suction airflow when the suction transmitted by the main drainage care mechanism 2 changes, so as to change the suction airflow and cause discomfort to the patient, and the amplitude detection component 34 is used to detect the frequency of the patient's movement, thereby providing data for the adjustment of the main drainage care mechanism 2, and the liquid storage mechanism 4 can provide the patient with a short-term drainage demand when the auxiliary drainage care mechanism 3 is temporarily separated from the main drainage care mechanism 2.

[0053] Reference Figures 3 to 5 The magnetic variable component 22 includes a connection box 221 fixedly connected to the upper end surface of the housing 21, a slide plate 222 is slidably connected to the inner wall of the connection box 221, an even number of electromagnets 223 are fixedly connected to the side of the slide plate 222 facing the housing 21, and the electromagnets 223 are electrically connected to the controller. The rod body of the telescopic end of the hydraulic press 23 is fixedly passed through the slide plate 222 and extends into the flow absorber 25;

[0054] The magnetic resistance assembly 24 includes a fixed plate 241 fixedly connected to the inner wall of the housing 21, and a permanent magnet 242 corresponding to the electromagnet 223 is fixedly connected to the side of the fixed plate 241 facing the connection box 221. The flow absorber 25 is fixedly connected to the inner wall of the housing 21 and the output end is connected to the main liquid storage tank 26 through a pipeline. The main liquid storage tank 26 is slidably connected to the inner bottom of the housing 21.

[0055] A data cable 27 and a straw 28 are fixedly connected to the side of the shell 21. The end of the data cable 27 facing the shell 21 is electrically connected to the controller. The end of the straw 28 facing the shell 21 passes through the shell 21 and is connected to the input end of the flow absorber 25. The other ends of the data cable 27 and the straw 28 are fixedly connected with a female connector 29.

[0056] The connecting box 221 in the magnetic variable component 22 can be used to make the slide 222 slide inside it. Since the slide 222 is connected to the rod body of the telescopic end of the hydraulic machine 23, the slide 222 will move synchronously with the movement of the telescopic end of the hydraulic machine 23. The controller provides the electromagnet 223 with the corresponding current intensity according to the detection result of the amplitude detection component 34, so that the electromagnet 223 generates the corresponding magnetic force. The magnetic force generated by the electromagnet 223 is opposite to the magnetic force of the permanent magnet 242. As the electromagnet 223 moves with the slide 222, the permanent magnet 242 in the magnetic resistance component 24 repels the electromagnet 223, thereby reducing the movement speed and frequency of the telescopic end of the hydraulic machine 23.

[0057] Reference Figures 6 to 8 A sub-connector 311 is fixedly connected to the side of the shell 31 facing the main drainage care mechanism 2, and the sub-connector 311 is clamped with the mother connector 29. Buckles 312 are fixedly connected to both sides of the length direction of the shell 31, and a fixing belt of a custom length is clamped inside the buckle 312. Two slideways 313 are fixedly connected to the length direction of the upper end surface of the shell 31, and two card slot blocks 314 are fixedly connected to the upper end surface of the shell 31. The upper end surface of the shell 31 located between the two slideways 313 is fixedly connected to a first connecting vessel 315.

[0058] The flow stabilizing component 32 includes a flow stabilizing box 321 fixedly connected to the bottom of the outer shell 31, and the interior of the flow stabilizing box 321 is fixedly connected with a honeycomb rectifier 322 and a one-way valve 323, and the one-way valve 323 and the honeycomb rectifier 322 are interconnected, and the other side of the flow stabilizing box 321 is connected to an air inlet pipe 3221, and the other end of the air inlet pipe 3221 passes through the outer shell 31 and is connected to the sub-connector 311, and the other side of the one-way valve 323 is connected to an air outlet pipe 3231.

[0059] By utilizing the snap connection between the mother connector 29 and the sub-connector 311, the electrical connection and suction connection between the main drainage care mechanism 2 and the auxiliary drainage care mechanism 3 can be achieved, wherein the flow stabilizing component 32 utilizes the honeycomb rectifier 322 and the one-way valve 323 to prevent backflow and airflow interruption when the suction airflow changes, and the one-way valve 323 can also prevent the suction provided by the liquid storage mechanism 4 from leaking from the sub-connector 311 when the main drainage care mechanism 2 and the auxiliary drainage care mechanism 3 are subsequently separated.

[0060] Reference Figures 9 and 10 The flow adjustment component 33 includes a flow box 331 fixedly connected to the inner bottom of the housing 31, and a π-shaped partition 332 is fixedly connected to the inner wall of the flow box 331.

[0061] The suction bucket 35 is located at the bottom of the outer shell 31. The suction bucket 35 has two input ends and one output end. The output end of the three-way block 333 is connected to one of the input ends of the suction bucket 35 through a pipeline, and the end of the air outlet pipe 3231 away from the one-way valve 323 is connected to the other input end of the suction bucket 35.

[0062] The π-shaped partition 332 in the flow adjustment component 33 can be used to divide the flow box 331 into multiple areas, and by setting up two diversion areas, dispersed absorption of suction can be achieved. At the same time, the absorbed liquid can also be temporarily stored to prevent the absorbed liquid from being blocked during the transmission process.

[0063] Reference Figures 9 to 11 An adjustment structure 334 is provided between the installation area and the suction area. The adjustment structure 334 includes a flow tube 3341 fixedly connected to the center of the π-shaped partition 332.

[0064] By utilizing the adjustment structure 334 located in the installation area and the suction area, when the suction changes, the corresponding suction flow rate can be adjusted according to the change. The porous sleeve 3345 utilizes the air collecting hood 3344 to collect the suction, and the elastic rod 3343 extends according to the suction strength, so that the holes at different stages in the porous sleeve 3345 are exposed from the circulation tube 3341 to achieve control based on suction to flow rate, and the liquid discharged from the holes of the porous sleeve 3345 will enter the suction area, and the liquid entering the suction area will be separated into the diversion areas on both sides, and collected through the three-way block, and then enter the main drainage care mechanism 2 through the flow stabilizing component 32.

[0066] The amplitude detection component 34 includes a detection box 341 fixedly connected to the bottom of the shell 31, and a trigger structure 342 is arranged at the center position of the inner wall around the detection box 341. The trigger structure 342 includes a pressure switch 3421 fixedly connected to the inner wall of the detection box 341, and the pressure switch 3421 is electrically connected to the data line 27. The inner wall of the detection box 341 is fixedly connected to a plurality of elastic telescopic rods 3422 in a circular array with the pressure switch 3421 as the center, and the telescopic ends of each elastic telescopic rod 3422 are fixedly connected to a connecting piece 3423, and the connecting piece 3423 is in contact with the pressure switch 3421, and the other side of the connecting piece 3423 is fixedly connected to a sliding rod 3424.

[0067] The trigger structures 342 are movably clamped together at one side away from the detection box 341 to hold a rotating ball 343. The rotating surface of the rotating ball 343 is provided with a plurality of sliding grooves 3431. The other end of the sliding rod 3424 is slidably connected to the sliding groove 3431.

[0068] The rotating ball 343 is a hollow structure, and an inertia structure 344 is arranged inside the rotating ball 343. The inertia structure 344 includes connecting covers 3444 fixedly connected to the spherical surface of the rotating ball 343 in four different directions.

Multiple elastic rods 3442 are commonly fixedly connected to a connecting square block 3441. The rod body of the elastic rod 3442 is movably sleeved with multiple inertia balls 3443.

[0069] By utilizing the inertial structure 344 in the rotating ball 343, when the patient moves, the inertial ball 3443 in the inertial structure 344 can be moved in the elastic rod 3442. The greater the patient's movement frequency, the higher the movement frequency of the inertial ball 3443 in the elastic rod 3442. The force generated when the inertial ball 3443 moves will be transmitted to the rotating ball 343, and then the rotating ball 343 will cause different squeezing of the elastic telescopic rod 3422 according to the different transmitted forces, and the connecting piece 3423 will cause different pressures on the pressure switch 3421, so that the control will not be based on the pressure transmitted by the pressure switch 3421, and the current patient's movement frequency can be obtained.

[0070] Reference Figure 6 , Fig.14 The liquid storage mechanism 4 includes two sliders 41 slidably connected in two slideways 313, the sliders 41 are fixedly connected with a buckle 44, and the buckle 44 is engaged with the slot block 314, the upper end surfaces of the sliders 41 are jointly fixedly connected with an auxiliary liquid storage tank 42, the output end of the auxiliary liquid storage tank 42 is fixedly connected with a second communicating vessel, the second communicating vessel is air-tightly engaged with the first communicating vessel 315, and the bottom of the auxiliary liquid storage tank 42 is fixedly connected with two lever-type pressers 43 in contact with the second communicating vessel.

[0071] The liquid storage mechanism 4 can provide short-term suction for the auxiliary drainage care mechanism when the patient moves at a high frequency (when the patient moves at a high frequency, the sub-connector 311 needs to be manually disconnected from the mother connector 29. After the sub-connector 311 is disconnected from the mother connector 29, the main drainage care mechanism 2 stops working and the amplitude detection component 34 also loses its effect).

[0072] The operating principle of this embodiment is as follows:

[0073] Step 1: First, according to the drainage position of the patient's drainage tube 36, select a fixing belt of corresponding length and pass it through the buckles 312 on both sides of the auxiliary drainage care mechanism shell 31 to fix it at the appropriate position on the patient's body surface (this position can be determined by medical staff according to actual conditions). Then, the sub-connector 311 of the auxiliary drainage care mechanism 3 is snap-connected with the female connector 29 of the main drainage care mechanism 2, so as to achieve the connection between the two in terms of circuit and suction transmission. At the same time, the auxiliary liquid storage tank 42 of the liquid storage mechanism 4 is slowly slid along the slide 313 on the upper end surface of the shell 31 through the slider 41 until the buckle 44 on the slider 41 is snap-connected with the slot block 314. During the installation process, pay attention to the correct direction of the auxiliary liquid storage tank 42 to ensure that the second connecting vessel at the output end of the auxiliary liquid storage tank 42 is connected to the first connecting vessel on the shell 31. A communicating vessel 315 is airtightly connected, and then the lever-type press fitter 43 is pressed to connect the second communicating vessel with the first communicating vessel 315. The lever-type press fitter 43 uses the lever principle to connect the first communicating vessel 315 with the second communicating vessel. Then the auxiliary liquid storage tank 42 is gently pressed by hand to check whether the connection is well sealed to prevent air leakage (the auxiliary liquid storage tank 42 is in an expanded state at this time), and then the main drainage nursing mechanism 2 is started by the controller (after the main drainage nursing mechanism 2 is started, the air in the auxiliary liquid storage tank 42 will be sucked out, so that the auxiliary liquid storage tank 42 is in a compressed state), so that the drainage tube 36 can complete the drainage of liquid (such as blood, exudate, pus, etc.) and gas (such as gas accumulation in the chest cavity) accumulated between the patient's tissues or in the body cavity through the suction force generated by the main drainage nursing mechanism 2;

[0074] Among them, when the main drainage care mechanism 2 is started, the hydraulic cylinder 23 is started first. The hydraulic cylinder 23 is the power source for the main drainage care mechanism 2 to generate suction. Its telescopic end moves up and down, driving the slide 222 connected to it to slide in the connecting box 221. During the movement of the slide 222, the telescopic end of the hydraulic cylinder 23 directly acts on the suction device 25, and the suction device 25 provides power to generate negative pressure inside the suction device 25, thereby forming suction, laying the foundation for subsequent drainage operations (the specific work of the main drainage care mechanism 2 is consistent with the negative pressure suction drainage working mode).

[0075] Among them, when the patient is performing daily activities such as turning over, sitting up, etc., the inertial structure 344 in the rotating ball 343 of the amplitude detection component 34 will generate inertial force. When the patient moves at a low frequency, such as turning over slowly, the inertial ball 3443 moves relatively slowly on the elastic rod 3442, and the movement amplitude is small; when the patient quickly gets up to get an item, the movement frequency is high, the movement speed of the inertial ball 3443 on the elastic rod 3442 is accelerated, and the movement distance is increased. The inertial force generated by the movement of the inertial ball 3443 is further transmitted to the rotating ball 343. After the rotating ball 343 is subjected to force, it squeezes the elastic telescopic rod 3422. The elastic telescopic rod 3422 is deformed after being squeezed, driving the connecting piece 3423 to move toward the pressure switch 3421 and generate pressure on it. The pressure varies with the patient's movement frequency. The higher the movement frequency, the greater the pressure. The pressure switch 3421 converts the pressure signal into an electrical signal and transmits it to the controller in real time through the data line 27;

[0076] After the controller receives the electrical signal from the amplitude detection component 34, it derives the movement frequency based on the size of the electrical signal. If the patient's movement frequency is low, the controller outputs a smaller current to the electromagnet 223 of the magnetic variable component 22, and the electromagnet 223 generates a weaker magnetic force; if the patient's movement frequency is high, the controller outputs a larger current, and the electromagnet 223 generates a stronger magnetic force (the movement frequency is proportional to the magnetic force of the electromagnet 223).

[0077] Since the electromagnet 223 moves with the slide 222 and generates a repulsive force with the permanent magnet 242 in the magnetic resistance component 24, when the magnetic force of the electromagnet 223 is weak, the repulsive force with the permanent magnet 242 is small, and the movement speed and frequency of the telescopic end of the hydraulic valve 23 are relatively fast; when the magnetic force of the electromagnet 223 is strong, the repulsive force increases, the movement speed of the telescopic end of the hydraulic valve 23 slows down and the frequency decreases, and the movement of the telescopic end of the hydraulic valve 23 provides power for the flow absorber 25. When the telescopic end of the hydraulic valve 23 moves fast and at a high frequency, the flow absorber 25 generates a large suction force; otherwise, a small suction force is generated, thereby realizing the precise adjustment of the drainage suction force according to the patient's movement state, thereby achieving the purpose of controlling the main drainage nursing mechanism 2 to generate corresponding suction force according to the patient's movement frequency.

[0078] Step 2: When the suction of the main drainage care mechanism 2 changes due to the change of the patient's movement state, the airflow (airflow refers to the suction airflow used to absorb liquid and gas in the patient's body) enters the flow stabilizing box 321 of the flow stabilizing component 32, and the honeycomb rectifier 322 rectifies the airflow, combing the turbulent airflow into a relatively stable airflow. The one-way valve 323 controls the direction of the airflow, only allowing the airflow to flow in from the air inlet pipe 3221 and flow out from the air outlet pipe 3231 after rectification by the honeycomb rectifier 322, preventing the airflow from flowing back. When the main and auxiliary drainage care mechanisms are separated, the one-way valve 323 can effectively prevent the suction provided by the liquid storage mechanism 4 from leaking from the sub-connector 311.

[0079] The π-shaped partition 332 divides the flow box 331 into an installation area, a suction area and two diversion areas. The two diversion areas can effectively disperse the suction force to avoid excessive local pressure. At the same time, the absorbed liquid can be temporarily stored to prevent the liquid from being blocked during the transmission process. When the suction force changes, the adjustment structure 334 between the installation area and the suction area starts to work. When the suction force increases, the air collecting cover 3344 will collect more suction force, so that the elastic rod 3343 is stretched by a greater pulling force, and the elastic rod 3343 is stretched. The stretching of 343 drives the porous sleeve 3345 to move outward in the circulation tube 3341, thereby exposing more holes and increasing the flow rate of suction. On the contrary, when the suction decreases, the elastic rod 3343 contracts, the porous sleeve 3345 moves inward, the exposed holes decrease, and the suction flow rate decreases. After the liquid enters the suction area from the holes of the porous sleeve 3345, it will be diverted to the diversion areas on both sides, and then collected through the three-way block 333, and finally enter the main drainage nursing mechanism 2 through the flow stabilizing component 32, so as to achieve balanced regulation of the suction airflow pressure;

[0080] The π-shaped partition 332 in the flow adjustment component 33 divides the flow box 331 into an installation area, a suction area and two diversion areas. The liquid flows into the installation area through the drainage pipe 36, and then enters the suction area through the adjustment structure 334, and then is dispersed to the two diversion areas for temporary storage. The input end of the three-way block 333 is connected to the two diversion areas through a pipeline, so that the liquid in the diversion area is collected, and the output end of the three-way block 333 is connected to one of the input ends of the suction bucket 35 through a pipeline. When the suction bucket 35 is working, suction is generated to suck the liquid collected by the three-way block 333 into itself. At the same time, the other input end of the suction bucket 35 It is connected to the air outlet pipe 3231 of the flow stabilizing component 32, and the flow stabilizing component 32 can stabilize the airflow, prevent backflow and interruption, and ensure that the airflow is stable when the suction bucket 35 is working. Since the main drainage nursing mechanism 2 is connected with the suction bucket 35, the suction pipe 28 of the main drainage nursing mechanism 2 and other air paths, under the suction force generated by the suction device 25 of the main drainage nursing mechanism 2, the liquid in the suction bucket 35 is transmitted to the suction pipe 28, and then enters the suction device 25 through the suction pipe 28. The output end of the suction device 25 is connected to the main liquid storage tank 26 through a pipeline, and finally the liquid is transported to the main liquid storage tank 26 for storage, which is convenient for subsequent processing and observation by medical staff.

[0081] Step 3: When the patient needs to move at a high frequency, such as going to the bathroom or undergoing a physical examination, the medical staff manually separates the sub-connector 311 from the mother connector 29. At this time, the main drainage care mechanism 2 stops working due to the disconnection of the circuit, and the amplitude detection component 34 can no longer detect the patient's movement frequency. At this time, the auxiliary liquid storage tank 42 in a compressed state provides a short suction force for the auxiliary drainage care mechanism 3. This short suction force can ensure that the drainage process will not be interrupted during the period when the main drainage care mechanism 2 stops working, so as to maintain the drainage effect.

[0082] When the auxiliary drainage care mechanism 3 is separated from the main drainage care mechanism 2 and the liquid storage mechanism 4 takes effect, the suction bucket 35 transmits the suction generated by the liquid storage mechanism 4 to the drainage tube 36 and other parts to maintain the continuity of drainage. After the suction bucket 35 transmits the suction of the auxiliary liquid storage tank 42, the drainage tube 36 can continue to drain the patient, ensuring that the drainage process is not interrupted during the period when the main drainage care mechanism stops working. The suction bucket 35 also regulates the airflow to avoid backflow or interruption of airflow due to changes in suction, maintain a stable drainage environment, and ensure the drainage effect of the patient.

[0083] When the patient has finished and returned to the bed, the medical staff reconnects the sub-connector 311 of the auxiliary drainage care mechanism 3 with the female connector 29 of the main drainage care mechanism 2. After the main drainage care mechanism 2 resumes working, the suction bucket 35 starts to work to generate suction, sucking the liquid sucked in the auxiliary liquid storage tank 42 and transmitting it to the main liquid storage tank 26 through the pipeline. As the liquid is continuously discharged, the pressure inside the auxiliary liquid storage tank 42 gradually decreases and finally returns to a compressed state. In this way, the auxiliary liquid storage tank 42 is prepared for drainage when the patient moves at a high frequency next time, ensuring the continuity and stability of the entire drainage care process.
