Description

Technical Field

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

[0002] A postoperative drainage device for surgical nursing is a medical device that discharges exudate, pus or gas from a postoperative wound through an indwelling drainage tube. Its core function is to maintain wound cleanliness, promote healing and prevent infection. During clinical use, the fixation effect of the drainage tube directly affects the drainage efficiency and patient comfort. If the fixation device fails to effectively fit the patient's body surface, it may cause the drainage tube to shift or fall off, resulting in the tip of the drainage tube deviating from the target position, causing accumulation of exudate, poor drainage or even reflux, increasing the risk of infection; therefore, how to design a fixation device that can dynamically adapt to the patient's body position changes and keep the drainage tube stable has become a key technical problem in improving the quality of postoperative care.

[0003] In the prior art, the patent document CN117959509A discloses an ascites drainer, which includes a fixing plate, double-sided tape, a guiding plate, a mounting plate, a rubber block, a connecting block, a cold-shrinkable tube and a support bar, etc. The fixing plate is provided with a through groove for a guide wire and a drainage tube to pass through. The double-sided tape is adhered to the side of the fixing plate, and the double-sided tape is used to fix the fixing plate on the patient's skin surface. The guiding plate and the mounting plate are both connected to the side of the fixing plate. The connecting block is connected to the side of the mounting plate through the rubber block. The cold-shrinkable tube is placed on the top surface of the connecting block. The support bar is arranged in a spiral shape inside the cold-shrinkable tube. By pulling out the support bar inside the cold-shrinkable tube, the cold-shrinkable tube can contract radially along its own elasticity and wrap the drainage tube, and then the cold-shrinkable tube can be fixed on the connecting block through an elastic rod and a rubber plug, so that the drainage tube can be quickly fixed on the patient's skin surface, avoiding the drainage tube from falling off, and the fixing effect is good.

[0004] However, the above device still has the problem of insufficient adaptive adjustment ability when dealing with the patient's long-term bedridden turning over, sitting up or getting out of bed activities. During the wearing process, the patient's activities will cause the fixation of the drainage tube to fall off from the skin. The unfixed drainage tube and the drainage tube that is difficult to adaptively extend or shorten will directly cause harm to the wound, increasing the patient's pain. Therefore, it is urgent to develop a postoperative drainage device for surgical nursing, a drainage device with a dynamic deformation compensation mechanism, which can real-time sense the state of the drainage tube and can adaptively adjust the fixing strength, reduce the incidence of complications, and improve the quality of the patient's postoperative rehabilitation. Summary of the Invention

[0005] To solve the above problems, the present invention provides a postoperative drainage device for surgical care, which houses and fixes the drainage tube through a box body design, and provides real-time feedback on the fixing effect of the box body. When a detachment force generated by the patient's movement occurs, the box body can adaptively adjust the fixing strength, reduce the incidence of complications, and improve the quality of the patient's postoperative rehabilitation.

[0006] To achieve the above object, the technical solution of the present invention is as follows: A postoperative drainage device for surgical care, comprising a drainage tube and a collecting tube box. The collecting tube box includes a box body and a box cover. The box cover is detachably connected to the box body. Symmetrically arranged tube passing holes and tube passing grooves are provided on the side wall of the box body.

[0007] A guiding component is provided inside the box body. The guiding component includes an elastic catheter placement groove plate, which is detachably connected to the inside of the box body. The catheter placement groove plate is a spiral downward groove plate structure. The drainage tube enters the box body through the tube passing hole and exits the box body through the tube passing groove. The part of the drainage tube located inside the box body is placed in the catheter placement groove plate.

[0008] A bottom plate is provided at the bottom of the box body. The center of the top surface of the bottom plate is provided with a telescopic cylinder. A plurality of suction cups with openings downward are provided at the bottom of the bottom plate. Adjustment sliding grooves corresponding to the positions of the suction cups are provided on the surface of the bottom plate. Adjustment sliders are slidably connected to the adjustment sliding grooves. Adjustment holes are provided on the surfaces of the adjustment sliders. Pressure rods are slidably fitted in the adjustment holes. The bottom ends of the pressure rods are fixedly connected to the corresponding suction cups. The side walls of the pressure rods are hinged to the outer wall of the telescopic cylinder. When the patient's movement causes the box body to displace away from the skin surface, the displacement of the telescopic cylinder following the box body is converted into the displacement of a plurality of pressure rods approaching the patient's skin. Each pressure rod applies pressure to the corresponding suction cup, and the magnitude of this pressure is proportional to the displacement of the telescopic cylinder.

[0009] The technical principle of the above solution is as follows: Through the design of the drainage tube and the collecting tube box, which serves as the basic structure of the device; the collecting tube box is composed of a box body and a box cover. The box cover is detachably connected to the box body, facilitating cleaning and maintenance. The design of the tube passing hole and the tube passing groove allows the drainage tube to enter the box body through the tube passing hole and exit the box body through the tube passing groove. The design of the guiding component realizes the effective housing and guiding of the drainage tube. The drainage tube is located in the catheter placement groove plate and is guided and fixed, avoiding the displacement or detachment of the drainage tube caused by the patient's movement; the suction cups are used to adsorb on the patient's body surface to keep the device stable; when the patient's movement causes the box body to displace away from the skin surface, the inner cylinder follows the displacement of the box body, and through the action of the adjustment sliding groove, the adjustment slider and the pressure rod, the displacement is converted into the displacement of a plurality of pressure rods approaching the patient's skin. The pressure rod applies pressure to the corresponding suction cup, thereby realizing close fitting and dynamic adjustment to the patient's body surface, reducing the probability of the box body detaching from the patient's skin.

[0010] The above solution has the following beneficial effects:

[0011] 1. In this solution, by designing a pipe placement groove plate structure that spirals downward, the internal space of the box body is effectively utilized to achieve the orderly storage of the drainage tube. This not only ensures the stability and safety of the drainage tube during storage but also avoids the discomfort and pressure that may be caused by the traditional scattered placement of the drainage tube on the patient's skin. At the same time, the elastic characteristics of the pipe placement groove plate ensure that the drainage tube is neither overly squeezed during storage nor can maintain a good drainage effect, thereby improving the patient's comfort level.

[0012] 2. In this solution, the suction cups and adjustment chute structures on the bottom plate enable the entire drainage device to closely fit the patient's skin surface. Even if the box body of the drainage device is displaced due to the patient's movement, through the linkage mechanism of the inner cylinder, the pressure rod, and the suction cup, when the patient moves, if the box body of the drainage device is displaced away from the skin surface, the telescopic cylinder will undergo telescopic changes accordingly. The telescopic changes of the telescopic cylinder will be converted into the displacement of the pressure rod relative to the adjustment slider. Since the side wall of the pressure rod is hinged to the outer wall of the telescopic cylinder, the pressure rod will rotate around the hinge point, thereby changing its angle and position relative to the patient's skin; the contact pressure and position between the suction cup and the patient's skin are adjusted in real-time to ensure the stable fixation of the drainage tube. This self-adaptive adjustment ability greatly reduces the risk of the drainage tube falling off or shifting due to unstable fixation, reduces the occurrence of exudate accumulation, poor drainage, or even reflux, and thus effectively prevents the occurrence of complications such as infection.

[0013] 3. In this solution, when the patient's movement causes the box body to tend to separate from the patient's skin, the movement of the box body will drive the pull rod to slide along with the slider in the adjustment chute. The adjustment holes on the surface of the adjustment slider provide a vertical sliding space for the pressure rod, enabling the pressure rod to move freely within a certain range. The sliding of the adjustment slider will further change the relative position between the bottom end of the pressure rod and the suction cup, thereby adjusting the contact pressure and position between the suction cup and the patient's skin.

[0014] Furthermore, a spring is provided at the bottom of the telescopic cylinder, and both ends of the spring are fixedly connected to the bottom end of the telescopic cylinder and the top wall of the bottom plate respectively.

[0015] Beneficial effects: The addition of the spring provides additional support and buffering for the telescopic cylinder. When the patient moves, the spring can absorb and disperse the impact force caused by the movement, reducing the direct collision between the telescopic cylinder and the outer cylinder, thereby enhancing the stability of the entire drainage device. This buffering effect helps prevent the detachment or displacement of the drainage device caused by sudden patient movement; the elastic characteristics of the spring enable the telescopic cylinder to automatically reset after the box body moves due to patient movement. When the patient's movement causes the box body to move away from the skin, the spring is compressed; when the movement stops, the elastic force of the spring pushes the telescopic cylinder back to its initial position, ensuring that the drainage device always fits closely with the patient's skin. This adaptive adjustment and reset function helps maintain the stable fixation of the drainage tube and ensure the drainage effect. In addition, the elastic characteristics of the spring enable the telescopic cylinder to automatically reset after the box body moves due to patient movement. When the patient's movement causes the box body to move away from the skin, the spring is compressed; when the movement stops, the elastic force of the spring pushes the telescopic cylinder back to its initial position, ensuring that the drainage device always fits closely with the patient's skin. This adaptive adjustment and reset function helps maintain the stable fixation of the drainage tube and ensure the drainage effect.

[0016] Furthermore, the tube-passing hole is located at the connection between the side wall of the box body and the box cover, and the height of the bottom end of the tube-passing groove is less than the height of the tube-passing hole.

[0017] Beneficial effects: By setting the tube-passing hole at the connection between the side wall of the box body and the box cover and adjusting the height of the tube-passing groove, a natural height difference can be formed when the drainage tube enters and exits the box body, which helps the drainage fluid to form a more smooth flow path inside the drainage tube, reducing the drainage resistance caused by bending or height change and improving the drainage efficiency. The design of the height difference can guide the drainage fluid to utilize the gravity effect and pass through the drainage tube more effectively, reducing the risk of drainage fluid accumulation and blockage caused by excessive tube bending or complex flow paths, and ensuring the continuity and stability of the drainage process.

[0018] Furthermore, a reinforcement layer is adhesively fixed to the bottom of the bottom plate, and the reinforcement layer is made of a hydrogel material.

[0019] Beneficial effects: The hydrogel material has good skin affinity and adhesiveness, and can closely fit the patient's skin to form an effective sealing barrier. In addition, the hydrogel material has good moisture retention and breathability, which can keep the patient's skin moist and comfortable, reducing problems such as skin dryness, itching or pressure sores caused by long-term wearing of the drainage device.

[0020] Furthermore, a regulating component for dynamically adjusting the telescopic resistance of the drainage tube is provided at the connection between the tube-passing groove and the catheter placement groove plate, and a torsion spring is fixedly connected to the bottom wall of the box body. One end of the torsion spring away from the bottom wall of the box body is detachably connected to the side wall of the catheter placement groove plate.

[0021] Beneficial effects: The detachable connection method of the torsion spring with the bottom wall of the box body and the side wall of the catheter placement groove plate not only simplifies the assembly and disassembly process of the drainage device, but also improves the stability and durability of its overall structure. The elastic restoring force of the torsion spring can ensure that the catheter placement groove plate quickly returns to its original position when subjected to external forces, maintaining its correct position and angle, thereby extending the service life of the drainage device.

[0022] Furthermore, the adjustment component includes a fixing plate. The fixing plate is provided with a 'U'-shaped clamping catheter groove corresponding to the shape of the catheter passing groove. One side of the fixing plate located inside the box body has a semi-circular ring. A number of telescopic rods are provided on the side wall of the semi-circular ring. The ends of the telescopic rods away from the semi-circular ring are all fixedly connected to the fixing plate. Symmetric displacement grooves are provided on both sides of the catheter passing groove corresponding to the position of the fixing plate. Symmetric slide rails are provided on the outer side wall of the box body. The two slide rails are respectively located between the two side displacement grooves and the clamping catheter groove. Horizontally sliding blocks are slidably connected to the slide rails. A blocking block is hinged to each of the two horizontally sliding blocks. Arc grooves corresponding to the shape of the side wall of the drainage catheter are provided on the side of the two blocking blocks close to each other. Symmetric transmission rod mechanisms are provided at the positions of the semi-circular ring corresponding to the two side displacement grooves. The ends of the transmission rod mechanisms away from the semi-circular ring are all hinged to the blocking blocks. The transmission rod mechanism is used to convert the displacement of the semi-circular ring approaching the fixing plate into the displacement of the horizontally sliding block on the slide rail.

[0023] Beneficial effects: Through the cooperation of the 'U'-shaped clamping catheter groove on the fixing plate and the semi-circular ring, the drainage catheter is firmly clamped therein, which not only ensures the stability of the drainage catheter, but also facilitates its smooth extension and retraction. At the same time, the symmetric displacement grooves provided on both sides of the catheter passing groove and the slide rail design on the outer side wall of the box body provide precise guidance for the sliding of the horizontally sliding block and the blocking block, ensuring the smoothness and controllability of the entire adjustment process; the design of the blocking block and the arc groove can provide dynamic support and resistance adjustment when the drainage catheter extends or retracts, not only effectively slowing down the extension or retraction speed of the drainage catheter, preventing potential damage to the wound caused by too fast or too violent actions, but also further increasing the friction force and protection of the side wall of the drainage catheter through the elastic layer in the arc groove; the application of the transmission rod mechanism converts the displacement of the semi-circular ring into the displacement of the horizontally sliding block on the slide rail, realizing precise control and dynamic adjustment of the extension amount of the drainage catheter, not only improving the adaptability of the drainage device, enabling it to better adapt to the drainage needs of patients in different activity states, enhancing the stability and safety of the device; in addition, as the extension amount of the drainage catheter increases, the blocking block gradually approaches the drainage catheter through the transmission action of the transmission rod mechanism, increasing the extension resistance of the drainage catheter, and also effectively preventing the problems of blockage and poor drainage of the drainage catheter through the pressing and dredging action of the elastic layer on the side wall of the drainage catheter.

[0024] Furthermore, a fixing layer for increasing the friction between the drainage catheter and the semi-circular ring is provided inside the semi-circular ring. The drainage catheter is clamped inside the fixing layer and extends outside the box body through the clamping catheter groove.

[0025] Beneficial effects: The design of the fixing layer ensures the stability of the drainage tube in a dynamic environment. When the patient moves or changes position, the drainage tube is often pulled or squeezed, and the fixing layer can tightly clamp the drainage tube, effectively preventing it from accidentally slipping or shifting, thereby maintaining the continuous and effective drainage of the drainage tube and avoiding problems such as exudate accumulation and poor drainage caused by the drainage tube falling off or shifting.

[0026] Furthermore, an elastic layer is provided in each arc groove for absorbing the horizontal pressure exerted by the resistance block on the drainage tube.

[0027] Beneficial effects: The design of the elastic layer can effectively alleviate the horizontal displacement or shaking that may occur when the drainage tube is subjected to external force, thereby enhancing the stability of the drainage tube in the device. By absorbing and dispersing these pressures, the risk of wear or damage to the drainage tube caused by improper movement is reduced, thereby ensuring the continuity and safety of the drainage process.

[0028] Furthermore, an optical flow meter is provided in the tube slot plate, and the optical flow meter signal is connected to the controller.

[0029] Beneficial effects: By real-time monitoring of the flow rate in the drainage tube, the patient's drainage situation can be quickly and accurately understood. For patients in the postoperative recovery period, the drainage rate is a key physiological indicator that directly reflects the discharge rate and recovery of the accumulated fluid in the body. The controller can perform real-time analysis of the working status of the drainage tube based on the received flow rate information. When an abnormal flow rate is found, an alarm can be issued in time to remind medical staff to deal with it, which helps to avoid potential complications and provides valuable time for medical staff to deal with emergencies.

[0030] Furthermore, an electric cylinder is fixedly connected to the fixed plate, the electric cylinder is connected to the controller signal, the output shaft of the electric cylinder is fixedly connected to the push plate, and the semicircular ring is located in the movement track of the push plate.

[0031] Beneficial effect: Through the signal connection between the controller and the electric cylinder, precise control of the push plate movement is achieved. When the controller receives the drainage tube blockage information transmitted by the optical flow meter, it can respond quickly and drive the electric cylinder to work. The reciprocating motion of the push plate can effectively clear the drainage tube, especially the blockage point. By generating repeated pressure differences, it helps to eliminate the blockage in the drainage tube and ensure a smooth drainage process.

[0044] The following is a further detailed description through specific embodiments:

[0045] Example 1:

[0046] As shown in the attached Figure 1 , Figure 2 , Figure 3 and Figure 4As shown: A postoperative drainage device for surgical care, including a drainage tube 2 and a manifold box 1. The manifold box 1 includes a box body 101 and a box cover 102. The box cover 102 is detachably connected to the box body 101. Symmetrically positioned pipe holes 3 and pipe grooves 4 are provided on the side wall of the box body 101. A guiding component for coiling and storing the drainage tube 2 is provided inside the box body 101. The guiding component includes an elastic tube placement groove plate 5. The tube placement groove plate 5 is a spiral downward groove plate structure. The drainage tube 2 is clamped inside the tube placement groove plate 5. The design of the spiral storage mechanism inside the box body 101, compared with the conventional storage method of pulling the drainage tube 2 straight and attaching it to the patient's skin surface, makes full use of the support and protection of the box body 101, reduces the probability of the drainage tube 2 being squeezed and blocked due to patient movement, and effectively reduces the contact area between the drainage tube 2 and the skin surface, ensuring the stability and safety of the drainage tube 2 during storage; The two ends of the spiral structure of the tube placement groove plate 5 are detachably communicated with the pipe holes 3 on both sides of the box body 101 respectively. A number of clamping rods 501 with decreasing arrangement heights are fixedly connected to the inner wall of the box body 101. A number of corresponding card slots are provided at the bottom end of the tube placement groove plate 5 corresponding to the shape and position of the clamping rods 501. The placement of the drainage tube 2 is limited by the clamping rod 501 card slots, aiming to optimize the layout and fixation of the drainage tube 2 and reduce potential risks caused by improper placement; In actual operation, after the medical staff inserts the drainage tube 2 at the patient's wound, the drainage tube 2 can be coiled and stored along the spiral track of the tube placement groove plate 5. Making full use of the elastic characteristics of the tube placement groove plate 5 to ensure that the drainage tube 2 will not be overly squeezed during storage and can maintain a good drainage effect. Subsequently, open the box body 101, accurately place the tube placement groove plate 5 into the box body 101 according to the preset positions of the pipe holes 3, pipe grooves 4 and clamping rods 501, and finally close the box cover 102. The whole storage process is both efficient and convenient; In summary, this design realizes the orderly storage and efficient management of the drainage tube 2, optimizes the deficiency of the traditional scattered attachment of the drainage tube 2 to the patient's skin, reduces the risk of compression and blockage of the drainage tube 2 caused by patient movement, and improves the space utilization rate.

[0047] The pipe hole 3 is located at the connection between the side wall of the box body 101 and the box cover 102. The height of the bottom end of the pipe groove 4 is less than the height of the pipe hole 3. The design of the pipe groove 4 and the pipe hole 3 can form a height difference between the inlet and outlet of the drainage tube 2 stored in the box body 101. Under normal circumstances, when the drainage tube 2 is coiled and stored in the box body 101, the internal flow path will become more complex due to the increase in bending points, increasing the resistance of the drainage fluid flowing in the pipeline and increasing the risk of blockage of the drainage tube 2. By introducing the design of the height difference and using the gravity effect, the drainage fluid is guided to form a smooth flow path inside the drainage tube 2, balancing the increase in the blockage risk of the drainage tube 2 caused by the coiled structure.

[0048] The activity of the patient is a major factor affecting the stability of the drainage tube 2. The bottom of the designed box body 101 is provided with a bottom plate 6. At the center of the top surface of the bottom plate 6, there is a telescopic cylinder 7. The telescopic cylinder 7 includes an outer cylinder 702 and an inner cylinder 701. The inner wall of the outer cylinder 702 is slidably matched with the outer wall of the inner cylinder 701. The outer cylinder 702 is integrally formed with the center of the bottom plate 6, while the inner cylinder 701 is integrally formed with the outer bottom wall of the box body 101. When the patient's activity causes the box body 101 to move away from the patient's skin surface, the design of the sliding fit between the outer cylinder 702 and the inner cylinder 701 provides a movable space for the box body 101. Compared with the fixed form without a movable space, when the patient has a sudden movement, this design can reduce the probability that the box body 101 is separated from the patient's skin due to the instantaneous force; the bottom of the bottom plate 6 is provided with a number of suction cups 8 with openings downward. The suction cups 8 are all made of silica gel material. The surface of the bottom plate 6 is provided with adjustment sliding grooves 9 corresponding to the positions of the suction cups 8. The adjustment sliding grooves 9 are all slidably connected with adjustment sliders 10. The surfaces of the adjustment sliders 10 are all provided with adjustment holes 11. The adjustment holes 11 are all slidably matched with pressure rods 12. The bottom ends of the pressure rods 12 are adhesively fixed to the corresponding suction cups 8. In particular, the side walls of the pressure rods 12 are all hinged to the outer wall of the inner cylinder 701 through connecting rods, specifically as Figure 4 shown. When the box body 101 is subjected to a pulling force to separate from the patient's skin, the upward displacement of the box body 101 drives the upward displacement of the inner cylinder 701. During the upward displacement of the inner cylinder 701, due to the limiting effect of the adjustment sliding groove 9 and the hinged mechanism of the connecting rod, a number of pressure rods 12 will show a downward pressing movement trajectory as the inner cylinder 701 rises. The downward pressing of a number of pressure rods 12 will press the corresponding suction cups 8. Since the adsorption effect of the suction cups 8 depends on the elasticity of the suction cups 8 themselves and the negative pressure inside the suction cups 8, when the top surface of the suction cups 8 is pressed, the air inside the suction cups 8 overflows outward, thereby improving the negative pressure effect inside the space of the suction cups 8, enhancing the fixing effect between a number of suction cups 8 and the patient, achieving a fixed effect of dynamic adjustment with the displacement of the box body 101 separating, reducing the probability that the box body 101 is separated from the patient's skin, and improving the guiding stability of the guiding mechanism inside the box body 101 for the drainage tube 2.

[0049] In particular, a spring 13 is further provided inside the outer cylinder 702. The two ends of the spring 13 are respectively welded to the bottom end of the inner cylinder 701 and the top wall of the bottom plate 6. The design of this spring 13, on the one hand, is used to slow down the separation trend of the box body 101, thereby further reducing the risk of the box body 101 falling off. On the other hand, after coping with a separation displacement movement, under the design of the spring 13, the inner cylinder 701 returns to its position to cope with the next separation risk displacement. During the return process, due to the reciprocating movement mechanism when the spring 13 expands and contracts, the box body 101 generates a reciprocating oscillation, and this oscillation is transmitted into the drainage tube 2 inside the box body 101, reducing the risk of blockage of the drainage tube 2 from the side.

[0050] In addition, in the traditional fixing mechanism of the drainage tube 2, the sweat secreted on the patient's skin surface will affect the fixing effect between the drainage tube 2 and the patient's skin surface. For this solution, the secretion of body fluids will also affect the degree of fitting between the box body 101 and the patient's skin, thereby affecting the guiding stability of the drainage tube 2. Therefore, by using the movement of several pressure rods 12 pressing down to cause the bottom plate 6 to move downward, a reinforcing layer 14 is adhesively fixed to the bottom of the bottom plate 6. The reinforcing layer 14 is made of a hydrogel material, and the hydrogel material has good skin affinity and adhesiveness, and can closely fit the patient's skin to form an effective sealing barrier. Therefore, when the bottom plate 6 moves downward, the hydrogel can quickly fit to the patient's skin, thereby enhancing the fixing effect between the bottom plate 6 and the patient's skin surface. Moreover, as the patient's sweat is secreted, the hydrogel can absorb this sweat, and its water retention and swelling properties will be further enhanced, resulting in an increase in the adhesion force between the hydrogel and the skin. Therefore, the fixing effect of the hydrogel will be improved, which can further improve the fixing stability, ensure that the drainage device is not easily detached, and provide safer and more reliable postoperative drainage care for the patient.

[0051] Embodiment 2:

[0052] As shown in Figure 2 , Figure 5 and Figure 6 shown, the difference from Embodiment 1 is that a torsion spring 15 is welded to the bottom wall of the box body 101, and one end of the torsion spring 15 away from the bottom wall of the box body 101 is detachably connected to the side wall of the catheter placement groove plate 5 through a snap structure. During the normal drainage process, when the patient's activities generate a tangential pulling force on the drainage tube 2, due to the elastic characteristics of the catheter placement groove plate 5, part of the drainage tube 2 will be pulled out of the box body 101. At this time, the design of the torsion spring 15, using the characteristic of the torsion spring 15 to store elastic energy, enables the drainage tube 2 to contract back into the box body 101 under the action of the restoring force applied by the torsion spring 15 when the tangential tensile force generated by the patient's activities is removed, thereby improving the storage stability of the catheter placement groove plate 5 for the drainage tube 2.

[0053] In addition, particularly, an adjusting component is provided at the connection between the pipe passing groove 4 and the catheter placing groove plate 5. The adjusting component includes a fixing plate 16. The fixing plate 16 is provided with a pipe clamping groove 17 having a 'U'-shaped structure corresponding to the shape of the pipe passing groove 4. On one side of the fixing plate 16 located inside the box body 101, there is a semi-circular ring 18. A number of telescopic rods are welded to the side wall of the semi-circular ring 18. Each telescopic rod includes an inner rod and a hollow outer rod. The outer side wall of the inner rod is slidably connected to the inner side wall of the outer rod. One end of the outer rod away from the semi-circular ring 18 is fixedly welded to the surface of the fixing plate 16. A fixing layer 25 is provided inside the semi-circular ring 18. The drainage tube 2 is clamped in the fixing layer 25 and extends outside the box body 101 through the pipe clamping groove 17. Symmetrical displacement grooves 19 are provided on both sides of the pipe passing groove 4 corresponding to the position of the fixing plate 16. Symmetrical slide rails 20 are provided on the outer side wall of the box body 101. The two slide rails 20 are respectively located between the two displacement grooves 19 on both sides and the pipe clamping groove 17. Horizontally sliding blocks 21 are slidably connected to the slide rails 20. A blocking block 22 is hinged to each of the two horizontally sliding blocks 21. On one side where the two blocking blocks 22 are close to each other, arc grooves 23 corresponding to the shape of the side wall of the drainage tube 2 are provided. Elastic layers 26 are provided in the arc grooves 23. Symmetrical transmission rod mechanisms 24 are provided at the positions of the semi-circular ring 18 corresponding to the two displacement grooves 19 on both sides. The two blocking blocks 22 are respectively hinged to the semi-circular ring 18 through the corresponding transmission rod mechanisms 24. Taking the transmission rod mechanism 24 on one side as an example, as Figure 6 shown, the transmission rod mechanism 24 includes a first hinge rod 2401, a second hinge rod 2402, and a third hinge rod 2403. The first hinge rod 2401, the second hinge rod 2402, and the third hinge rod 2403 are hinged to each other. One end of the first hinge rod 2401 away from the second hinge rod 2402 is hinged to the side wall of the semi-circular ring 18. One end of the third hinge rod 2403 away from the second hinge rod 2402 is hinged to the corresponding blocking block 22. During the process of the drainage tube 2 extending out of the box body 101 due to the patient's movement, through the design of the fixing layer 25, the movement of the drainage tube 2 will cause the semi-circular ring 18 to move closer to the fixing plate 16. At this time, the hinging of the first hinge rod 2401, the second hinge rod 2402, and the third hinge rod 2403 will transmit this vertical displacement into the horizontal displacement of the blocking block 22. And through the hinged design of the blocking block 22 and the horizontally sliding block 21, under the driving displacement of the connecting rod mechanism, the blocking block 22 will move closer to the drainage tube 2 and have a vertical displacement on one side of the arc groove 23, that is, an effect similar to 'clamping the drainage tube 2' is achieved. As the extension amount of the drainage tube 2 increases, this 'clamping effect' will also increase dynamically. At this time, the design of the elastic layer 26 generates a horizontal pressure and a tangential frictional force on the side wall of the drainage tube 2. The tangential frictional force is used to slow down the extending trend of the drainage tube 2, achieving the effect that the extending resistance gradually increases as the drainage tube 2 extends; and the horizontal pressure will gradually tilt due to the hinging of the blocking block 22, achieving a pressing and dredging effect similar to 'peristalsis' on the drainage tube 2, realizing a dynamic self-dredging effect and reducing the risk of blockage of the drainage tube 2.

[0054] Embodiment 3:

[0055] As shown in the Figure 7 accompanying drawings, the difference from Embodiment 2 is that an optical flowmeter is provided in the catheter placement groove plate 5. The optical flowmeter is preferably a fiber optic flow sensor. The optical flowmeter is signal-connected to a controller. An electric cylinder 27 is fixedly connected to the fixing plate 16 by bolts. The electric cylinder 27 is signal-connected to the controller. The output shaft of the electric cylinder 27 is fixedly connected to a push plate 28 through a coupling. The semi-circular ring 18 is located in the movement track of the push plate 28. During the normal drainage process, the optical flowmeter is used to monitor the flow rate of the drainage tube 2 located in the catheter placement groove plate 5, and the flow rate information is transmitted to the controller for analysis. When there is a blockage in the drainage tube 2, the controller transmits a signal to the electric cylinder 27 to drive the electric cylinder 27 to reciprocally extend and shorten, so that the semi-circular ring 18 reciprocally moves in the direction close to the fixing plate 16. Combining the dredging process of the above-mentioned blocking block 22, a repeated pressure difference is generated on both sides of the blockage point in the drainage tube 2, thereby dredging the blocked drainage tube 2, realizing the blockage monitoring and active dredging of the drainage tube 2, and realizing automatic drainage assistance.

[0056] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
