Description
A suctioning and rinsing device Technical Field
[0001] This invention relates to the field of sputum suction medical device technology, specifically a sputum suction nursing and rinsing device. Background Technology
[0002] To maintain airway patency in patients with respiratory diseases, a suction device is usually used during monitoring to clear sputum from the airway. During suctioning, a disposable suction tube is installed on the suction hose of the suction device. The negative pressure power source inlet is connected to the gas chamber of the sputum collection bottle. The power source continuously extracts air from the bottle, creating and maintaining negative pressure in the sputum collection bottle. The sputum in the negative pressure state is then suctioned into the sputum collection bottle through the suction hose and the disposable suction tube.
[0003] Most existing portable single-pump electric suction devices typically only have one suction tube. When the suction tube becomes contaminated with thick sputum, the machine needs to be stopped to flush the suction tube. Otherwise, the thick sputum inside the suction tube will obstruct the smooth suctioning of sputum from the disposable suction tube. However, stopping the machine will interrupt the suctioning process and affect the timely removal of sputum. For critically ill patients who require continuous suctioning, interrupting suctioning can easily increase the risk of airway obstruction, requiring the use of a backup suction device, which increases costs. Although wall-mounted negative pressure suction devices can achieve non-stop flushing through a T-valve, this structure relies on the hospital's central air supply and cannot be directly transferred to reusable portable electric suction devices. Therefore, a suctioning care flushing device that can simultaneously flush the suction tube during suctioning is needed. Summary of the Invention
[0004] The purpose of this invention is to provide a suction and rinsing device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] The sputum suction and irrigation device includes the main body of the suction device, and also includes:
[0007] A sputum collection bottle is inserted and installed into the main body of the suction device. A suction tube is fixedly connected between the sputum collection bottle and the main body of the suction device. A bottle cap is detachably installed on the open end of the sputum collection bottle. The inside of the bottle cap is connected to a cylindrical cavity and two round holes. A drain tube connected to the cylindrical cavity is fixed on the bottle cap. A movable seal is provided at the bottom of each round hole connected to the sputum collection bottle. Above the movable seal, the cylindrical cavity and the two round holes are interconnected.
[0008] The suction and irrigation assembly includes two movable tubes that slide into a circular hole. The upper end of each movable tube is connected to a suction tube, and the lower end of each movable tube can pass through a movable seal at the bottom of the corresponding circular hole and extend into the sputum collection bottle. The two suction tubes are connected and fixed to a rotating block at the end away from the movable tubes. A disposable suction tube is connected and fixed to the rotating block. The disposable suction tube can maintain communication with one of the suction tubes. A flushing tube that can deliver saline to the suction tube is connected and fixed to the rotating block. When the disposable suction tube is maintained in communication with one of the suction tubes, the other suction tube is connected to the flushing tube.
[0009] The drive assembly includes a first gear rotatably connected to the bottle cap, the first gear externally meshing with two toothed columns capable of driving two movable tubes to move synchronously in opposite directions.
[0010] Furthermore, a fixed tube that is connected and fixed to the bottle cap is connected and fixed to the suction pipe, and a filter is connected and fixed to the suction pipe.
[0011] Furthermore, the bottom opening of the circular hole is rotatably connected to a return baffle, the inner bottom surface of the bottle cap is fixed with a fixing block, the return baffle is fixed with a shaft rotatably connected to the fixing block, the return baffle can movably seal the bottom opening of the circular hole under the action of elastic restoring force, and can be opened under the pressure of the moving tube, allowing the moving tube to penetrate into the sputum collection bottle.
[0012] Furthermore, two positioning blocks are fixed on the outer side of the bottle cap, which are respectively slidably connected to the corresponding toothed column, and a motor capable of driving the first gear to rotate is fixed on the outer side of the bottle cap.
[0013] Furthermore, one end of the rotating block is provided with a flushing chamber that is fixedly connected to the flushing pipe. By rotating the sealing cover, it can be ensured that when the second connecting pipe is connected to one of the first connecting pipes, the other first connecting pipe is connected to the flushing chamber.
[0014] Furthermore, one end of the rotating block is rotatably connected to a sealing cap, and two first connecting pipes are fixedly connected to the sealing cap. The first connecting pipes are fixedly connected to the suction hoses at corresponding positions.
[0015] The outside of the sputum collection bottle is detachably connected to and fixed with a first cylinder and a second cylinder. The outside of the first cylinder is connected to and fixed with a first pipe and a second pipe. The first pipe is connected to the sputum collection bottle.
[0016] Furthermore, a third pipe and a fourth pipe are fixedly connected to the outer side of the second cylinder, the third pipe is connected to the sputum collection bottle, and a liquid storage tank is fixedly connected to the top of the fourth pipe.
[0017] Furthermore, both the first and second cylinders are equipped with flow-blocking components, each including a connecting shaft, and multiple partition plates are uniformly fixed to the outside of the connecting shaft.
[0018] Furthermore, a second gear is fixed to one end of the connecting shaft, and a rack is fixed to the gear post, the rack meshing and rotating with the second gear at the corresponding position.
[0019] Compared with the prior art, the beneficial effects of the present invention are:
[0020] 1. Two movable tubes are movably inserted into the cap of the sputum collection bottle. Each movable tube is connected to a suction tube at its top. A sealing cap is fixed between the two suction tubes. A rotating block is rotatably connected to the inside of the sealing cap. A disposable suction tube and a flushing tube are connected and fixed to the rotating block. The two movable tubes can be driven to alternately connect to the sputum collection bottle by a drive component. At the same time, rotating the rotating block can alternately connect the two suction tubes to the disposable suction tube. When the disposable suction tube draws sputum into the sputum collection bottle through a suction tube, if there is thick sputum adhering to the inside of the suction tube and it needs to be cleaned, another clean suction tube and movable tube can be switched to connect to the disposable suction tube. At the same time, another set of suction tubes and movable tubes can be cleaned, so that the suction tube can continuously draw the patient's sputum and effectively prevent the suction tube from being blocked by thick sputum from smoothly drawing sputum from the disposable suction tube.
[0021] 2. By creating a flushing chamber inside the rotating block, when the suction tube with thick sputum adhering to its inner wall rotates away from the disposable suction tube, it will connect with the flushing chamber. The external saline pumping pipe delivers saline to the flushing chamber through the flushing pipe. The saline in the flushing chamber then enters the dirty suction tube, transporting the sputum inside the suction tube along the suction tube, the movable tube, the columnar cavity, and the drainage tube to the outside. At the same time, another suction tube can still perform sputum suction. This allows for simultaneous sputum suction with a clean suction tube and flushing of a dirty suction tube, improving the flushing efficiency of the suction tube and facilitating continuous sputum suction.
[0022] 3. By connecting and fixing a sleeve to the outside of the sputum collection bottle, during the process of the drive component driving the two movable tubes to move alternately in opposite directions to switch the suction tubing, the drive component will drive multiple partition plates inside the first cylinder to rotate. During the rotation of the multiple partition plates, the sputum collection bottle will discharge part of the mixture of physiological saline and sputum inside the sputum collection bottle to the outside through the first cylinder, preventing the sputum collection bottle from being filled with too much mixture and thus requiring the machine to be stopped and the mixture inside the sputum collection bottle to be emptied. This helps to extend the working time of the sputum collection bottle for continuous sputum suction.
[0023] 4. A second cylinder is fixedly connected to the outside of the sputum collection bottle, and a storage tank is fixedly connected to the top of the second cylinder. The storage tank contains physiological saline. During the process of the drive component driving the first cylinder to operate and discharge part of the mixed liquid, the drive component will also drive multiple partition plates inside the second cylinder to rotate, releasing part of the physiological saline in the storage tank into the sputum collection bottle. This prevents the physiological saline content inside the sputum collection bottle from decreasing due to discharge. Sufficient physiological saline can mix and dilute the sputum in the sputum collection bottle after it is inhaled, and achieve the effect of sterilizing and reducing the bacteria in the sputum.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0034] Example 1, please refer to Figures 1-8. In this embodiment of the invention, a suction nursing irrigation device includes a suction device body 100, a sputum collection bottle 200 placed on the suction device body 100, a suction tube 310 fixedly connected between the sputum collection bottle 200 and the suction device body 100, a bottle cap 300 detachably installed on the opening of the sputum collection bottle 200, a cylindrical cavity 320 and two round holes 330 opened inside the bottle cap 300, the cylindrical cavity 320 and the two round holes 330 are interconnected, a drain tube 340 connected to the cylindrical cavity 320 is fixedly fixed on the bottle cap 300, and a suction irrigation assembly 400 is arranged above the bottle cap 300. The suction irrigation assembly 400 includes two movable tubes 410 that are slidably inserted into the corresponding round holes 330, and a suction hose 420 is fixedly connected to the top of the movable tubes 410. The two suction hoses 420 are connected and fixedly connected to each other. There is a rotating block 430, on which a disposable suction tube 440 is detachably connected and fixed. A flushing tube 432 is connected and fixed on the rotating block 430. The flushing tube 432 can deliver saline to the suction tube 420. A drive assembly 500 is also provided on the outside of the bottle cap 300, which can drive two movable tubes 410 to move up and down synchronously in opposite directions in the vertical direction. The drive assembly 500 includes a first gear 510 rotatably connected to the bottle cap 300. Two parallel vertically arranged toothed columns 520 are meshed on the outside of the first gear 510. One end of each toothed column 520 is connected to the sliding tube 410. One side of each toothed column 520 is slidably connected to a corresponding positioning block 370. The positioning block 370 limits the toothed column 520. The other side of each toothed column 520 is provided with teeth to achieve meshing connection with the first gear 510.
[0035] Specifically, two suction tubes 420 are selectively connected and fixed to a traditional sputum collection bottle 200. When thick sputum adheres to the inside of one suction tube 420, the positions of the two movable tubes 410 can be adjusted by rotating the rotating block 430 and the drive assembly 500 to connect and fix the clean spare suction tube 420 to the disposable suction tube 440. At the same time, the flushing tube 432 is used to flush the replaced dirty suction tube 420 to clean the sputum adhering to the inside of the suction tube 420 (how is the precise docking of 432 and the replaced 420 achieved? The positional relationship needs to be clearly defined? The other end of the suction tube 420 is connected to the cover 300, how is it cleaned? The entire operation process needs to be clearly defined without contaminating the existing equipment). The cleaned suction tube 420 can be used for suctioning again, thus ensuring that there is always a clean suction tube 420 for suctioning. This facilitates continuous suctioning operations in the suctioning care flushing device, and the dirty suction tube 420 can be flushed during suctioning, which also helps to improve the flushing efficiency of the suction tube 420.
[0036] As shown in Figures 1 and 3, in this embodiment, a fixing tube 311 is connected and fixed to the bottom of the suction tube 310, and the fixing tube 311 is connected and fixed to the bottle cap 300. A filter 312 is connected in series in the middle of the suction tube 310. The top of the suction tube 310 is connected to the negative pressure power source inside the suction device body 100. A portable handle is fixed to the top of the suction device body 100. A control panel is provided on the outside of the suction device body 100. The control panel is provided with a negative pressure adjustment knob and a suction device body 100 start switch. The above-mentioned suction device body 100 related structures are existing technologies, and the detailed working principle of the relevant existing technology structures will not be described in detail.
[0037] In use, the user can carry the device to the bed where suctioning is needed by holding the handle. During the suctioning process, the negative pressure power source uses the suction tube 310 and the fixed tube 311 to draw air from the inside of the sputum collection bottle 200, so that the sputum collection bottle 200 is in a negative pressure state, which allows the suction tube 420 connected to the sputum collection bottle 200 to suction sputum from the patient's trachea and larynx. The existing component filter 312 can prevent the mixture of sputum and water as well as particles from entering the pump body, protecting the negative pressure system. As the last barrier, the filter 312 can keep liquids, blood, drug crystals, etc. in front of the negative pressure power source pump.
[0038] As shown in Figures 3 and 4, in this embodiment, two circular holes 330 are respectively connected and arranged on both sides of the cylindrical cavity 320. Multiple fixing blocks 360 are fixed on the inner bottom surface of the bottle cap 300. A shaft is rotatably inserted between the middle of the multiple fixing blocks 360. Two return baffles 350 are fixed on the outer side of the shaft. The two return baffles 350 are respectively arranged directly below the corresponding circular holes 330. A torsion spring is sleeved between the shaft and the fixing blocks 360. The return force of the torsion spring drives the return baffles 350 to rotate and abut against the bottom of the circular holes 330, thereby sealing the bottom opening 330 of the circular holes.
[0039] In this embodiment, referring to Figure 6, for example, when the left suction tube 420 and the corresponding movable tube 410 need cleaning, the bottom of the left movable tube 410 moves upward into the interior of the circular hole 330. The return baffle 350 below the movable tube 410 seals the bottom of the left circular hole 330. When cleaning is performed through the flushing tube 432, the saline solution entering the rotating block 430 through the flushing tube 432 can flow through the suction tube 420, then from the bottom end of the suction tube 420 through the left movable tube 410 into the columnar cavity 320 and the circular hole 330, and finally discharged along the drain tube 340. The drain tube 340 can be pre-connected to an external waste liquid recovery container, thereby realizing the internal flushing and cleaning of one of the suction tubes 420 and the movable tube 410. The bottom end of the right-side movable tube 410 extends into the sputum collection bottle 200. Under the action of the movable tube 410, the right-side return baffle 350 rotates and opens against the elastic force of the torsion spring. The negative pressure environment inside the sputum collection bottle 200 provides the power to draw sputum from the outside into the sputum collection bottle 200, drawing sputum from the disposable suction tube 440, suction tubing 420, and movable tube 410 into the sputum collection bottle 200. Subsequently, the cleaned left-side movable tube 410 can also be lowered to connect with the sputum collection bottle 200. The clean left-side movable tube 410 can carry the clean suction tubing 420 connected to it for suctioning. Similarly, when it is necessary to clean other tubes such as the right-side movable tube 410 and suction tubing 420, the same cleaning operation is used, so that the two suction tubing 420 can be used alternately for suctioning.
[0040] As shown in Figures 2 and 7, in this embodiment, two positioning blocks 370 are fixed on the outer side of the bottle cap 300 and are respectively slidably connected to the corresponding toothed column 520, thereby ensuring that the two toothed columns 520 can stably perform linear reciprocating movement in the vertical direction. A C-shaped plate is fixed on the outer side of the bottle cap 300, and a motor 380 that can drive the first gear 510 to rotate is fixed on the inner side of the C-shaped plate.
[0041] In use, when it is necessary to switch between the two movable tubes 410 and the suction tubing 420 for suctioning by moving the two movable tubes 410 up and down alternately, the output end of the motor 380 drives the first gear 510 to rotate forward and backward. The two gears 520 that mesh with the first gear 510 can move up and down alternately. The gears 520 then drive the two movable tubes 410 to move up and down alternately, so that one of the two movable tubes 410 is always connected to the sputum collection bottle 200 for suctioning, while the other movable tube 410 can move into the round hole 330 of the bottle cap 300 for rinsing.
[0042] As shown in Figures 5 and 6, in this embodiment, the rotating block 430 has a flushing chamber 431 that is fixedly connected to the flushing tube 432. One end of the rotating block 430 is fixedly connected to a second connecting tube 460, which is detachably connected to an existing disposable suction tube 440. The second connecting tube 460 is rotatably connected to the other end of one of the rotating blocks 430 with a sealing cap 450. Two first connecting tubes 451 are fixedly connected to the sealing cap 450. The two first connecting tubes 451 are detachably connected to the top of the suction tube 420 at the corresponding position. By rotating the sealing cap 450, it can be ensured that when the second connecting tube 460 can be connected to one of the first connecting tubes 451, the other first connecting tube 451 is connected to the flushing chamber 431.
[0043] In this embodiment, when the inner wall of the suction tube 420 connected to the first connecting tube 451 is covered with thick sputum and needs to be rinsed, the sealing cap 450 on the rotating block 430 is rotated, and the two rotate relative to each other. This controls the first connecting tube 451 on the dirty suction tube 420 to rotate to a position connected to the rinsing chamber 431. At this time, the position of the other first connecting tube 451 is connected to the position of the second connecting tube 460. The cleaning fluid, such as physiological saline (pure water and distilled water can also be used for temporary rinsing), is pumped through the rinsing tube 432 to the rinsing chamber 431. Then, the physiological saline enters the first connecting tube 451 and the suction tube 420, thus cleaning the sputum inside the suction tube 420 and the corresponding movable tube 410.
[0044] In this embodiment, the existing disposable suction tube 440 used in conjunction with the device is also provided with a negative pressure control side hole. After the operator inserts the suction tube to the appropriate depth, he presses the side hole with his thumb or forefinger. The outside air is cut off, and a negative pressure is instantly formed inside the tube to start suctioning. When the finger is released, air enters, the negative pressure is released, and suctioning stops immediately, thus achieving the function of flexibly controlling the start and stop of suctioning. The detailed operating principle of the disposable suction tube 440 will not be described in detail.
[0045] In Example 2, based on Example 1, in order to discharge part of the mixed liquid inside the sputum collection bottle 200 during the suctioning process and prevent excessive mixed liquid from affecting the suctioning of sputum in the sputum collection bottle 200, an appropriate amount of physiological saline is added to the inside of the sputum collection bottle 200 to mix with the sputum. The saline can reduce foam and aerosols, making it easier to clean the sputum collection bottle 200 afterward.
[0046] As shown in Figures 2, 7, and 8, in this embodiment, a first cylinder 600 and a second cylinder 700 are detachably connected and fixed to the outside of the sputum collection bottle 200. A first pipe fitting 610 and a second pipe fitting 620 are connected and fixed to the outside of the first cylinder 600. The first pipe fitting 610 is detachably connected and fixed to the sputum collection bottle 200. The second pipe fitting 620 is connected to an external container pipe for collecting sewage. A third pipe fitting 710 and a fourth pipe fitting 720 are connected and fixed to the outside of the second cylinder 700. The third pipe fitting 710 is detachably connected and fixed to the sputum collection bottle 200. A storage tank 721 is connected and fixed to the top of the fourth pipe fitting 720. The storage tank 721 contains pre-stored physiological saline.
[0047] In this embodiment, both the first cylinder 600 and the second cylinder 700 are provided with a flow-blocking component 800. The flow-blocking component 800 includes a connecting shaft 810. Multiple partition plates 820 are fixed at equal angles in an annular shape on the outer side of the connecting shaft 810. A second gear is fixed to one end of the connecting shaft 810 that passes through the first cylinder 600 or the second cylinder 700. A rack 530 is fixed on the gear post 520. The rack 530 meshes with the second gear at the corresponding position and rotates.
[0048] Specifically, a first cylinder 600 is connected to the bottom of the sputum collection bottle 200, and a second cylinder 700 is connected to the top of the sputum collection bottle 200. When the driving component 500 drives the two movable tubes 410 to exchange positions with the two suction tubes 420, the first cylinder 600 can be driven to intermittently communicate with the sputum collection bottle 200 to discharge a mixture of physiological saline and sputum, so that the sputum collection bottle 200 can be used continuously for a long time. At the same time, the driving component 500 can drive the second cylinder 700 to intermittently replenish an appropriate amount of physiological saline into the sputum collection bottle 200.
[0049] In this embodiment, the inner diameters of the two cylinders (including the first cylinder 600 and the second cylinder 700) are different, with the inner diameter of the first cylinder 600 being larger than that of the second cylinder 700. The purpose of this design is that during the up-and-down movement of the two toothed columns 520, the amount of mixed liquid discharged by the first cylinder 600 is greater than the amount of physiological saline added to the sputum collection bottle 200. This ensures that although the amount of mixed liquid inside the sputum collection bottle 200 is reduced, the physiological saline component used to mix with sputum is still present in the mixed liquid. The size of the partition plate 820 inside the two cylinders is also designed to be adapted to the inner diameter of the cylinders, with the outer side of the partition plate 820 rotating and abutting against the inner side of the cylinder.
[0050] In specific implementation, referring to Figure 8, when the first gear 510 rotates clockwise, the left tooth column 520 moves upward and the right tooth column 520 moves downward. The rack 530 on the tooth column 520 will rotate the second gear, which in turn rotates the connecting shaft 810. The connecting shaft 810 will rotate multiple partition plates 820. Inside the first cylinder 600, during the rotation of the multiple partition plates 820, the first pipe 610 will discharge the mixed liquid inside the sputum collection bottle 200 through the second pipe 620. Inside the second cylinder 700, during the rotation of the multiple partition plates 820, the saline solution inside the storage tank 721 will fall into the second cylinder 700 along the fourth pipe 720, and then be discharged from the second cylinder 700 through the third pipe 710 into the sputum collection bottle 200. The opening of the storage tank 721 is screwed and fixed with a cover plate. Opening the cover plate allows the addition of saline solution to the storage tank 721.
[0051] In this embodiment, the length of the rack 530 can be designed so that a single movement can drive the second gear to rotate one revolution, so that the multiple partition plates 820 can return to their initial positions inside the cylinder after rotating one revolution. The initial position of the partition plates 820 inside the first cylinder 600 is shown in Figure 8. At this time, the two adjacent partition plates 820 can block the first tube 610, so that the sputum collection bottle 200 is in a sealed environment during sputum suction. Similarly, the initial position of the partition plates 820 inside the second cylinder 700 is shown in Figure 7. At this time, the two adjacent partition plates 820 can block the third tube 710, so that the sputum collection bottle 200 is also in a sealed environment during sputum suction, and also prevents the saline solution inside the second cylinder 700 from continuously entering the sputum collection bottle 200.
[0052] As shown in Figure 3, in this embodiment, the sputum collection bottle 200 is provided with a first through hole 210 and a second through hole 220. The first through hole 210 and the second through hole 220 are respectively connected to the third pipe 710 and the first pipe 610, so that the first cylinder 600 and the second cylinder 700 can be intermittently connected to the sputum collection bottle 200 by means of the partition plate 820.
[0053] In this invention, the rinsing of the suction tubing 420 is mainly a temporary rinsing during the suctioning process. After the suctioning operation is completed, the disposable suction tube 440 can be removed, and then the rotating block 430 and the sealing cap 450 can be removed from the suction tubing 420. Next, the first cylinder 600 and the second cylinder 700 can be removed from the sputum collection bottle 200. Finally, the bottle cap 300 can be loosened and removed from the sputum collection bottle 200, which facilitates centralized rinsing and disinfection of the rotating block 430, the sealing cap 450, and the sputum collection bottle 200.
[0054] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
