Description

Technical Field

[0001] This invention relates to a suction device, and more particularly to a suction device for clinical nursing. Background Technology

[0002] Suctioning devices mainly include electric multi-functional negative pressure suctioning devices and simple manual suctioning devices. The operating end needs to be connected to a suction tube or sponge suction tube to be used. Electric suctioning devices are commonly used. They have a power switch and a manual control switch. They use the principle of negative pressure to perform suctioning and oral care. They are simple and easy to learn. They are used for routine suctioning of sputum, tracheotomy and other treatments for wounded and sick personnel. They are suitable for military combat medical care as well as for timely suctioning of sputum in hospitals or homes when there is respiratory mucus or vomit.

[0003] Currently, there are still some defects and shortcomings in the use of suction devices. The specific areas that need improvement are as follows:

[0004] 1. Most existing suction devices work by inserting the suction tube into the patient's throat to suction sputum. During this process, medical staff need to manually support the suction tube to prevent it from shaking, which increases their workload.

[0005] 2. During the use of existing suction devices, the gas produced is mostly discharged directly from inside the device, which may lead to the discharge of germs, thus affecting the health of other patients in the ward.

[0006] 3. Most existing suction devices are not easy to disassemble during use, which makes the cleaning and disinfection process of the device inconvenient and affects its subsequent use. Summary of the Invention

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention, through the coordinated use of the elastic band, mask, and anti-bite fixing sleeve, can quickly support and limit the suction tube during sputum suctioning of a patient's throat, ensuring the stability of the suction tube during use. This effectively avoids the need for medical staff to constantly manually support the suction tube to prevent it from shaking, as is common with existing suction devices. The anti-bite fixing sleeve prevents patients from unconsciously biting the suction tube during sputum suction, thus avoiding interference with the suction process. The threaded connection between the suction connecting tube and the sealing component allows for easy removal of the suction tube and connecting tube after use, facilitating cleaning and disinfection and preventing infection in subsequent patient use.

[0020] 2. This invention utilizes the interaction of a motor, a limiting sleeve, a concave support rod, and a Z-shaped rotating rod to drive a push frame to move left and right. The push frame moves a push-pull rod to the left, which, in turn, with the cooperation of a piston, a suction canister, and a suction tube, draws air out of the sputum collection box, creating negative pressure inside. At this point, with the cooperation of an L-shaped connecting tube, a suction connecting tube, and a suction tubing, sputum from the patient's throat is drawn into the sputum collection box, thus achieving the process of suctioning sputum from the patient's throat.

[0021] 3. The present invention, through its designed push frame, can move the push-pull rod to the right after drawing sputum into the sputum collection box. At this time, the interaction between the piston, extraction canister, and suction tube can blow gas back into the sputum collection box. Under the action of the air pressure inside the sputum collection box, the square baffle can be moved upward. At this time, the gas carrying bacteria inside the sputum collection box can enter the interior of the disinfection box through the interaction between the L-shaped exhaust pipe and the annular exhaust block. Then, under the action of the disinfection and deodorizing liquid inside the disinfection box, the air entering the disinfection box can be disinfected and deodorized, preventing the air carrying germs from being directly discharged into the ward, thereby avoiding the impact on the health of other patients in the ward.

[0022] 4. This invention utilizes the coordinated operation of sprocket one, motor, and sprocket two to drive shaft three to rotate during sputum suction. The rotation of shaft three, under the action of the stirring wheel, agitates the disinfection and deodorizing liquid inside the disinfection box, allowing the air entering the disinfection box to fully contact the disinfection and deodorizing liquid, thereby effectively increasing the disinfection and purification effect of the device. The disinfected and purified air is then discharged from the inside of the disinfection box through the exhaust pipe.

[0023] 5. This invention utilizes the interaction between the electric hydraulic rod, L-shaped rod, hinge rod one, and rotating plate to drive the two corresponding sliding plates closer together. This closer proximity of the two sliding plates, coupled with the interaction between the L-shaped toothed plate and gears, drives the rotating shaft two to rotate. The rotation of the rotating shaft two, in conjunction with the interaction between the hinge rod two, hinge rod three, and fixed rod two, moves the sealing assembly upwards to a suitable position. At this point, the sputum collection box and disinfection box can be easily removed from the device, facilitating cleaning and disinfection of their interiors. Attached Figure Description

Detailed Implementation

[0037] 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.

[0038] like Figure 1-12As shown, the present invention provides a technical solution: a sputum suction device for clinical nursing, including a mounting base plate 1. The upper end of the mounting base plate 1 has a placement groove 15 and a placement groove 16. A sputum collection box 7 is connected inside the placement groove 15. A sealing component 6 is connected to the upper end of the sputum collection box 7. The left end of the sealing component 6 is threadedly connected to the right end of the suction tube assembly 8. A suction component 9 is fixedly connected to the upper side of the sealing component 6. The suction component 9 is driven by a chain and a sprocket 10. Through the cooperation of the suction component 9, the sealing component 6, and the suction tube assembly 8, the patient's pharynx can be suctioned. Sputum from the throat is drawn into the sputum collection box 7. During this process, the sealing component 6 seals the sputum collection box 7, preventing odors from escaping. During sputum extraction, the suction component 9 drives the sprocket 10 to rotate. The sprocket 10 is fixedly connected to the upper end of the sealing component 6. Two limiting blocks 4 are fixedly connected to both the front and rear ends of the sealing component 6. A disinfection box 12 is attached to the lower right side of the sealing component 6, and the lower end of the disinfection box 12 is attached to the inside of the placement slot 16. The front and rear ends of the sealing component 6 are respectively connected to... Two lifting components 3 are fixedly connected at their relatively close ends. The lower ends of both lifting components 3 are fixedly connected to the upper end of the mounting base plate 1. Four limiting blocks 4 are movably connected to four T-shaped limiting rods 5, and the lower ends of the four T-shaped limiting rods 5 are fixedly connected to the upper end of the mounting base plate 1. Casters 2 are provided at the four corners of the bottom surface of the mounting base plate 1. A push handle 11 is provided on the right end of the upper surface of the mounting base plate 1. A battery 13 and a control panel 14 are provided on the upper surface of the mounting base plate 1. The mutual cooperation between the limiting blocks 4 and the T-shaped limiting rods 5 can limit the movement direction of the sealing component 6. The two lifting components 3 can move the sealing component 6 upwards, making it easy to remove the sputum collection box 7 and the disinfection box 12 from the mounting base 1. This facilitates cleaning of the inside of the sputum collection box 7 and the disinfection box 12. The disinfection box 12 can store an appropriate amount of disinfectant and deodorizing liquid, which disinfects and deodorizes the air inside the sputum collection box 7, preventing the air carrying germs from being directly released into the air and thus affecting the health of other patients in the ward.

[0039] Both lifting components 3 include two fixed plates 31. The lower ends of the four fixed plates 31 are fixedly connected to the upper end of the mounting base plate 1. The four fixed plates 31 are paired together, with their relatively close ends fixedly connected to the left and right ends of four fixed rods 32. The four fixed rods 32 are paired together and movably connected to four sliding plates 36, each with two circular holes inside. The four sliding plates 36 are paired together, with L-shaped rods 314 movably connected to their relatively close ends. The four L-shaped rods 314 are movably connected to one end of four hinge rods 310. The four hinge rods 310 are paired together, with their other ends movably connected to two rotating plates 311, each with two hinge shafts at their relatively far ends. The two rotating plates 31... 1. Two rotating shafts 312 are fixedly connected to each other. The two rotating shafts 312 are movably connected to two support plates 315. The lower ends of the two support plates 315 are fixedly connected to the upper end of the fixed base plate 1. The support plates 315 can support the rotating shafts 312. The cooperation between the fixed plate 31 and the fixed rod 32 can limit the movement direction of the sliding plate 36. By driving the two right sliding blocks 36 to move to the left, the two left sliding plates 36 can be driven to move to the right under the cooperation of the hinge rod 310 and the rotating plate 311, so as to drive the corresponding two sliding plates 36 to move closer to each other. The effect is that each of the four sliding plates 36 is fixedly connected to an L-shaped toothed plate 38 at its relatively far ends. The four L-shaped toothed plates 38 mesh with four gears 316 respectively. The four gears 316 are fixedly connected to four rotating shafts 37 respectively. Each of the four rotating shafts 37 is fixedly connected to a hinge rod 33 at its relatively far ends. The upper ends of each of the four hinge rods 33 are movably connected to a hinge rod 34. The upper ends of each of the four hinge rods 34 are movably connected to four fixed rods 39 respectively. Each of the four fixed rods 39 is fixedly connected to the front and rear ends of the sealing assembly 6 at its relatively close ends. Each of the four rotating shafts 37 is movably connected to a support plate 35. The lower ends of each of the four support plates 35 are fixedly connected to the mounting base. At the upper end of plate 1, the left ends of the two fixed plates 31 on the right are fixedly connected to electric hydraulic rods 313. The left ends of the two electric hydraulic rods 313 are respectively fixedly connected to the right ends of the two sliding blocks 36 on the right. By the mutual approach between the corresponding two sliding plates 36, the four rotating shafts 37 can be driven to rotate under the mutual cooperation between the L-shaped toothed plate 38 and the gear 316. The two rotating shafts 37 rotate in opposite directions. The rotation of the four rotating shafts 37 can achieve the effect of moving the sealing assembly 6 upward under the mutual cooperation between the hinge rod 33, the hinge rod 34 and the fixed rod 39. The support plate 35 can support the rotating shafts 37.

[0040] The sealing assembly 6 includes a sealing cover plate 61. The front and rear ends of the sealing cover plate 61 are fixedly connected to four fixing rods 39. The sealing cover plate 61 overlaps the upper end of the sputum collection box 7 via a rubber sealing gasket at its lower end. An L-shaped connecting pipe 63 is fixedly connected to the left side of the sealing cover plate 61. The L-shaped connecting pipe 63 is threadedly connected to the right end of the suction tube assembly 8 via a connector at its left end. A connecting box 64 is fixedly connected to the sealing cover plate 61 via an internal vent hole. A T-shaped rod 66 is movably connected to the connecting box 64 via a circular hole at its upper end. A square baffle 65 is fixedly connected to the lower end of the T-shaped rod 66. The lower end of the square baffle 65 overlaps the upper end of the sealing cover plate 61. The square baffle 65 is compatible with the connecting box 64. A spring 67 is sleeved on the rod 66. An L-shaped exhaust pipe 68 is fixedly connected to the right end of the connecting box 64. The lower right end of the L-shaped exhaust pipe 68 is fixedly connected to the sealing cover plate 610. The lower end of the sealing cover plate 610 overlaps the upper end of the disinfection box 12. The sealing cover plate 610 can seal the sputum collection box 7, preventing the air carrying bacteria inside the sputum collection box 7 from being directly discharged into the ward, which could affect the health of other patients in the ward. The L-shaped connecting pipe 63 is threadedly connected to the suction tube assembly 8, which allows the suction tube assembly 8 to be easily removed from the device after use and cleaned and disinfected, preventing infection of patients during subsequent use. The interaction between the spring 67, T-shaped rod 66, and square baffle 65 effectively seals the vent hole on the sealing cover 61. When the suction assembly 9 blows air into the sputum collection box 7, the air pressure causes the square baffle 65 to move upward. At this time, the air carrying bacteria inside the sputum collection box 7 can enter the disinfection box 12 through the L-shaped exhaust pipe 68 for disinfection and deodorization, effectively preventing the direct exhaust of air from the sputum collection box 7 from polluting the air inside the ward. Two fixing plates 69 are fixedly connected to the left side of the sealing cover 610. The left ends of the two fixing plates 69 are fixedly connected to the right end of the sealing cover 61. The sealing cover 610 passes through its internal... A rotating shaft 613 is movably connected to the connecting hole of the part. A sprocket 10 is fixedly connected to the upper end of the rotating shaft 613. The lower end of the rotating shaft 610 passes through the annular exhaust block 611 and is fixedly connected to the stirring wheel 612. One-way valves 62 are provided on the L-shaped exhaust pipe 68 and the L-shaped connecting pipe 63. The sealing cover 61 is fixedly connected to the lower front end of the suction assembly 9 through a circular hole opened inside its right side. The upper end of the sealing cover 61 is fixedly connected to the lower end of the suction assembly 9. The annular exhaust block 611 is fixedly connected to the lower end of the L-shaped exhaust pipe 68 through a circular hole opened inside its upper end. Two fixing rods 614 are fixedly connected to the upper end of the annular exhaust block 611. The upper ends of the two fixing rods 614 are fixedly connected to the lower end of the sealing cover 610.An exhaust pipe 615 is fixedly connected to the right side of the sealing cover 610. The sealing cover 610 is secured by a fixing plate 69. The rotation of the sprocket 10 drives the rotating shaft 613 to rotate. The rotation of the shaft 613, under the action of the stirring wheel 612, causes the disinfection and deodorizing liquid stored inside the disinfection chamber 12 to agitate, thereby increasing the contact area between the air entering the disinfection chamber 12 and the disinfection and deodorizing liquid, improving the disinfection and deodorization effect of the device. The annular exhaust block 611 also increases the contact area between the air entering the disinfection chamber 12 and the disinfection and deodorizing liquid. The air, after disinfection and deodorization, can be discharged from the inside of the disinfection chamber 12 through the exhaust pipe 615.

[0041] The suction tube assembly 8 includes a suction connecting tube 85, which is threaded to an L-shaped connecting tube 63 with a connector on its left end via a threaded structure on its right end. A suction tubing 82 is fixedly connected to the left end of the suction connecting tube 85. The lower side of the suction tubing 82 is fixedly connected to an anti-bite fixing sleeve 83. The anti-bite fixing sleeve 83 is fixedly connected to a face mask 84 with a circular hole at its upper end. The front and rear ends of the face mask 84 are respectively fixedly connected to the upper ends of an elastic band 81, which are relatively close to each other. The face mask 84, the anti-bite fixing sleeve 83, and the elastic band 81 are connected together. The cooperation between the two components enables rapid positioning of the suction tube 82, effectively avoiding the need for medical staff to manually support and position the traditional suction tube during use. The anti-bite fixing sleeve 83 prevents patients from unconsciously biting the suction tube 82, thus affecting the suction process. The threaded connection between the suction connecting tube 85 and the left L-shaped connecting tube 63 allows for easy removal of the device after use, facilitating cleaning and disinfection of the suction tube assembly 8.

[0042] The suction assembly 9 includes an L-shaped fixing plate 91, the lower end of which is fixedly connected to the upper end of a sealing cover plate 61. The L-shaped fixing plate 91 is fixedly connected to a motor 912 through a connecting hole inside its upper end. A sprocket 99 is fixedly connected to the output shaft of the motor 912. The sprocket 99 is connected to a sprocket 10 via a chain. The motor 912 is fixedly connected to the upper end of a Z-shaped rotating rod 94 via its output shaft. The lower end of the Z-shaped rotating rod 94 is movably connected to a push frame 95. The lower end of the push frame 95 is fixedly connected to both the front and rear sides. Two limiting sleeves 93 are movably connected to two concave support rods 92, respectively. The lower ends of the two concave support rods 92 are fixedly connected to the upper end of the sealing cover plate 61. A push-pull rod 96 is fixedly connected to the right end of the push frame 95. The right end of the push-pull rod 96 passes through the left side wall of the extraction can 910 and is fixedly connected to the left end of the piston 97. The piston 97 is adapted to the extraction can 910. Two fixing brackets 911 are fixedly connected to the extraction can 910. The lower ends of the two fixing brackets 911 are fixedly connected to the upper end of the sealing cover plate 61. The right side of the extraction can 910... A suction tube 98 is fixedly connected to the end. The lower front end of the suction tube 98 is fixedly connected to a sealing cover plate 610 with a circular hole on the right side. The L-shaped fixing plate 91 provides support for the motor 912. The rotation of the output shaft of the motor 912 drives the sprocket 10 to rotate under the action of the sprocket 2 99 and the chain. During the rotation of the output shaft of the motor 912, the Z-shaped rotating rod 94 is driven to rotate. The rotation of the Z-shaped rotating rod 94 drives the push frame 95, push-pull rod 96, piston 97, and extraction can 91 to rotate. The gas inside the sputum collection box 7 can be extracted through the cooperation of the suction tube 98, creating a negative pressure inside the sputum collection box 7. At this time, the sputum in the patient's throat can be drawn into the sputum collection box 7 through the cooperation of the L-shaped connecting tube 63, the suction connecting tube 85, and the suction tubing 82. After the sputum is drawn into the sputum collection box 7, the gas can be transported back into the sputum collection box 7 through the cooperation of the push frame 95, the push-pull rod 96, the piston 97, the extraction can 910, and the suction tube 98.

[0043] The operation steps of this invention are as follows:

[0044] When using this device to extract sputum from a patient's throat, firstly, add an appropriate amount of disinfectant and deodorizing liquid into the disinfection box 12. Then, under the action of the lifting component 3, the lower side of the sealing component 6 overlaps the upper end of the sputum collection box 7 and the disinfection box 12 respectively, thereby achieving a sealing effect on the sputum collection box 7 and the disinfection box 12. Next, insert the suction tube 82 into the patient's throat and make the patient's upper and lower teeth bite down on the anti-bite fixing sleeve 83. Then, fix the mask 84 to the patient's face through the elastic band 81. At this time, the suction tube 82 can be supported and positioned, and the operator does not need to manually support the suction tube 82 at all times.

[0045] After the suction tubing 82 is placed, the motor 912 is started. The rotation of the output shaft of the motor 912, under the action of the Z-shaped rotating rod 94, can drive the push frame 95 to move left and right. By driving the push-pull rod 96 to move to the left, the interaction between the piston 97, the suction canister 910 and the suction tube 98 can create negative pressure inside the sputum collection box 7. At this time, the interaction between the L-shaped connecting tube 63, the suction connecting tube 85 and the suction tubing 82 can draw the sputum produced in the patient's throat into the sputum collection box 7, so that the device can achieve the effect of suctioning sputum.

[0046] After the sputum from the patient's throat is drawn into the sputum collection box 7, the pusher 95 moves the push-pull rod 96 to the right. Then, with the cooperation of the piston 97, the extraction canister 910 and the suction tube 98, air can be blown into the sputum collection box 7. At this time, under the action of the air pressure inside the sputum collection box 7, the square baffle 65 can be moved upward. Then, the air carrying bacteria inside the sputum collection box 7 can be discharged into the disinfection box 12 through the L-shaped exhaust pipe 68 and the annular exhaust block. Then, under the action of the disinfection and deodorizing liquid inside the disinfection box 12, the air entering the disinfection box 12 can be disinfected and purified.

[0047] During the rotation of the output shaft of motor 912, sprocket 2 99 can be driven to rotate. The rotation of sprocket 2 99, under the action of sprocket 1 10, can drive shaft 3 613 to rotate. The rotation of shaft 3 613, under the action of stirring wheel 612, can realize the stirring process of disinfection and deodorization liquid inside disinfection box 12, so that the air entering the disinfection box 12 can fully contact the disinfection and deodorization liquid, thereby improving the disinfection and purification effect of the device on the air entering the disinfection box 12. The disinfected and purified air can be discharged from the inside of disinfection box 12 through exhaust pipe 615.

[0048] When the device is finished and the interior of the sputum collection box 7 and the disinfection box 12 needs to be cleaned, the two electric hydraulic rods 313 are activated to move the two right sliding plates 36 to the left. Then, with the cooperation of the hinge rod 310, the L-shaped rod 314 and the rotating plate 311, the two left sliding plates 36 can be moved to the right. As the two corresponding sliding plates 36 approach each other, with the cooperation of the L-shaped toothed plate 38 and the gear 316, the four rotating shafts 37 can be rotated. Through the rotation of the four rotating shafts 37, with the cooperation of the hinge rod 33, the hinge rod 34 and the fixing rod 39, the sealing assembly 6 can be moved upward to the appropriate position. At this time, the sputum collection box 7 and the disinfection box 12 can be easily removed from the mounting base plate 1 and disinfected and cleaned.
