Description

Technical Field

[0001] This invention relates to the field of sputum suction devices, specifically sputum suction devices. Background Technology

[0002] The sputum clearance device is a postural drainage method that replaces traditional manual chest percussion, vibration, and directional squeezing. It can expel sputum that has been retained in the lungs or deep effusions through multi-directional vibration, squeezing, and directional drainage. In addition, its most unique function is that it can improve pulmonary blood circulation, prevent venous stasis, relax respiratory muscles, improve overall muscle tone, enhance respiratory muscle strength to produce a cough reflex, and promote physical recovery.

[0003] Patients may experience airway obstruction and atelectasis due to reasons such as foreign bodies, phlegm, or inflammation after surgery. These conditions should be cleared promptly. Due to the decline in various bodily functions in the elderly, lung tissue elasticity and cough reflex are reduced. In order to achieve the purpose of airway clearance, help remove residual secretions in the patient's airway, keep the airway open, and avoid the problem that the elderly have difficulty in expelling phlegm from their airways, which may affect subsequent treatment, the use of a sputum expectoration device can make the process more effortless.

[0004] To prevent cross-infection during use, existing sputum suction devices typically cover the vibrating head with disposable gauze to ensure cleanliness. However, the process of covering and replacing the gauze is time-consuming, and the increased friction reduces patient comfort. Furthermore, the vibrating head is often placed externally in these devices, exposing it to air. This necessitates frequent cleaning with alcohol and cleaning solutions, which is laborious and inefficient, impacting work efficiency. In high-traffic hospital environments, this leads to significant workload for staff. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a sputum suction device to solve the technical problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sputum suction device, comprising a housing, a motor housing installed inside the housing, a second insertion block movably mounted at one end of the motor housing, an inner rod at one end of the second insertion block, a slot at one end of the inner rod, a carrying plate fixedly mounted at one end of the inner rod, a movable plate movably mounted at one end of the housing, a slider fixedly mounted at one end of the movable plate, a steel cable mounted at one end of the slider, an outer rod movably mounted on the outer side of the inner rod, connecting blocks fixedly mounted on both sides of the outer rod, the slider and the connecting blocks being connected by a steel cable, a fixed rod on one side of the motor housing, the fixed rod being connected to the second insertion block by a belt, a rotating rod on one side of the fixed rod, the rotating rod being connected to the fixed rod by a belt, and a spiral blade mounted on the outer side of the rotating rod.

[0007] By adopting the above technical solution, and by setting up a carrier plate and a movable plate, when the vibrating head is placed inside the carrier plate, the pressure of the vibrating head causes the inner rod to move downward, thereby driving the outer rod to move downward. Under the action of the No. 1 steel cable, the movable plate moves towards the center, sealing the vibrating head and preventing the vibrating head from having a large area of ​​contact with the outside air, thus reducing the risk of external airborne infection. At the same time, through the set No. 2 insert block and the inner rod, when the inner rod rotates, it drives the carrier plate to rotate, causing the carrier plate to rotate and clean the surface of the vibrating head, resulting in better cleaning effect. It eliminates the need for manual cleaning by staff, preventing infection and achieving an automatic cleaning effect. It also improves work efficiency and avoids the need for staff to manually clean the vibrating head every time it is used in a hospital environment with high traffic, reducing workload.

[0008] The invention is further configured such that a movable rod is movably installed on one side of the box, and a collar is fixedly installed at one end of the movable rod. The collar is made of flexible hose. A second steel cable is installed on one side of the movable rod. An installation plate is movably installed at one end of the box, and the installation plate is connected to the movable rod by the second steel cable.

[0009] By adopting the above technical solution, the movable rod and the No. 2 steel cable are installed so that the No. 2 steel cable can pull the installation plate during the movement of the movable rod. This allows the cleaning fluid in the water tank to enter the carrier plate through the spiral blade for cleaning. The movable rod triggers the water supply system, avoiding resource waste and making the cleaning effect more thorough.

[0010] The present invention is further configured such that a first insert block is movably installed on one side of the mounting plate, a second slot is provided at one end of the fixing rod, and the second slot cooperates with the first insert block. A locking block is sleeved on the outside of the first insert block, and the locking block is connected to the rotating rod by a belt.

[0011] By adopting the above technical solution and setting up a first insert and a second slot, the first insert can enter the second slot more stably, avoiding the problem of insufficient rotational transmission efficiency. At the same time, it avoids the problem of the first insert being difficult to insert into the second slot, thus improving the overall working stability.

[0012] The invention is further configured such that an arc-shaped block is provided on one side of the movable rod, and a spring is installed at one end of the arc-shaped block; a slot that matches the arc-shaped block is opened at one end of the housing; and the movable rod and the housing are slidably connected.

[0013] By adopting the above technical solution and setting an arc-shaped block, the movable rod can be limited by the arc-shaped block after it has moved, preventing the movable rod from automatically resetting and ensuring that the water supply system can work normally, thus avoiding the problem of water supply system interruption caused by the automatic resetting of the movable rod.

[0014] The present invention is further configured such that a water tank is installed inside the box body, and a water pipe is installed on one side of the water tank; a water trough is opened inside the box body, and an installation groove that cooperates with the water pipe is opened on one side of the water trough; and a water outlet is opened at one end of the water trough.

[0015] By adopting the above technical solution and setting up a water tank, the water flow can move along the water tank during the transportation process without deviating from the direction of the water flow. At the same time, the water outlet can discharge the water flow to one side of the carrying plate, so that the carrying plate can be cleaned with cleaning fluid during the cleaning process.

[0016] The present invention is further configured such that two pulleys are provided on both sides of the second steel cable, and there are multiple sets of second pulleys, and the outer side of the second pulley is provided with a slot that cooperates with the second steel cable.

[0017] By adopting the above technical solution and setting the No. 2 pulley, the movement of the No. 2 steel cable can be made more labor-saving, without generating large friction, reducing power consumption, and extending the service life of the No. 2 steel cable. This enables the purpose of moving the mounting plate upwards simply by sliding the movable rod.

[0018] The invention is further configured such that the movable plates are arranged in two opposing sets, and a pulley is provided on one side of the first steel cable, with a slot on the outer side of the pulley that matches the first steel cable.

[0019] By adopting the above technical solution, the setting of the movable plate and the No. 1 steel cable can reduce the friction of the No. 1 steel cable during movement, making the movement of the movable plate easier and requiring less force.

[0020] The present invention is further configured such that an electric box is installed on one side of the box body, and a drive line is installed on one side of the electric box. A vibrating head is installed at one end of the drive line, and the driving power inside the electric box is transmitted to the vibrating head through the drive line.

[0021] By adopting the above technical solution and setting up the drive line, the power inside the electric box can be transmitted to the vibrating head, enabling the vibrating head to vibrate and thus promoting the normal operation of sputum removal.

[0022] The present invention is further configured such that a limiting block is installed at one end of the inner rod, and multiple sets of limiting blocks are provided; a groove that cooperates with the limiting block is opened at one end of the carrying plate; the cross-section of the limiting block is triangular; bristles are provided on the inner side of the carrying plate; and a reset spring is installed at one end of the connecting block.

[0023] By adopting the above technical solution and setting a limiting block, the limiting block can fit with the loading plate, thereby making the transmission of the inner rod more effective and avoiding the problem that the inner rod is difficult to rotate to drive the loading plate to rotate, thus greatly reducing the cleaning effect of the vibrating head.

[0024] In summary, the present invention has the following main beneficial effects:

[0025] 1. This invention features a carrying plate and a movable plate. When the vibrating head is placed inside the carrying plate, the pressure of the vibrating head causes the inner rod to move downwards, which in turn moves the outer rod downwards. Under the action of the first steel cable, the movable plate moves towards the center, sealing the vibrating head and preventing it from having a large contact area with the outside air, thus reducing the risk of infection from external air. Simultaneously, through the second insert block and the inner rod, the rotation of the inner rod causes the carrying plate to rotate, allowing the carrying plate to rotate and clean the surface of the vibrating head, resulting in better cleaning. This eliminates the need for manual cleaning by staff, preventing infection and achieving automatic cleaning. It also improves work efficiency and avoids the need for staff to manually clean the vibrating head every time it is used in high-traffic hospital environments, reducing workload.

[0026] 2. This invention sets up a movable rod and a mounting plate. By moving the movable rod, the first insertion block is connected to the fixed rod, allowing the spiral blade to rotate. When the spiral blade rotates, it can transport the cleaning fluid in the water tank to the carrier plate, thereby cleaning the vibrating head. The cleaning fluid can achieve a more thorough cleaning effect, and there is no need for staff to wear cleaning gloves during manual cleaning, reducing usage and cleaning costs while improving work efficiency.

[0027] 3. By setting a collar, the present invention can fix the vibrating head by placing the drive wire inside the collar during the installation process, without the need for manual support. In addition, the collar made of flexible tubing makes it more convenient to remove and place the drive wire, eliminating the need for complicated manual handling operations, thus improving work efficiency and reducing work intensity.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] The embodiments of the present invention will now be described.

[0040] sputum suction device, such as Figure 1-9 As shown, the device includes a housing 1, inside which a motor housing 26 is installed. A second insertion block 25 is movably mounted on one end of the motor housing 26. An inner rod 5 is located on one end of the second insertion block 25, and a slot 22 is formed on one end of the inner rod 5. A carrying plate 13 is fixedly mounted on one end of the inner rod 5. A movable plate 4 is movably mounted on one end of the housing 1, and a slider 23 is fixedly mounted on one end of the movable plate 4. A steel cable 16 is mounted on one end of the slider 23. An outer rod 11 is movably mounted on the outside of the inner rod 5, and connecting blocks 24 are fixedly mounted on both sides of the outer rod 11. The slider 23 and the connecting blocks 24 are connected by the steel cable 16. A fixed rod 19 is located on one side of the motor housing 26, and the fixed rod 19 is connected to the second insertion block 25 by a belt. A rotating rod 15 is located on one side of the fixed rod 19, and the rotating rod 15 is connected to the fixed rod 19 by a belt. A spiral blade 14 is installed on the outside of the rotating rod 15. When the movable rod 8 moves, it pulls the second steel cable 32, causing the mounting plate 17 to shift. When the mounting plate 17 shifts, the first insertion block 18 enters the second slot 28 at one end of the fixed rod 19, causing the locking block on the outside of the first insertion block 18 to rotate. Through the belt, the rotating rod 15 rotates. When the rotating rod 15 rotates, it drives the spiral blade 14 to rotate. At this time, the cleaning fluid flows through the water tank 20 into the water pipe 27 under the action of the spiral blade 14, and then enters the outlet through the water trough 30, finally falling into the interior of the carrier plate 13. At this time, the carrier plate 13 rotates, cleaning the vibrating head 3 with the cleaning fluid. This can minimize the risk of cross-infection of bacteria and also eliminate the need to cover the surface of the vibrating head 3 with gauze, enhancing the patient's comfort.

[0041] Please see Figure 4 A movable rod 8 is movably installed on one side of the tank body 1, and a collar 7 is fixedly installed at one end of the movable rod 8. The collar 7 is made of flexible hose. A second steel cable 32 is installed on one side of the movable rod 8, and an installation plate 17 is movably installed at one end of the tank body 1. The installation plate 17 and the movable rod 8 are connected by the second steel cable 32. Through the movable rod 8 and the second steel cable 32, the second steel cable 32 can pull the installation plate 17 during the movement of the movable rod 8, so that the cleaning fluid in the water tank 20 enters the carrying plate 13 through the spiral blade 14 for cleaning. The water supply system is triggered by the movable rod 8 to avoid resource waste and make the cleaning effect more thorough.

[0042] Please see Figure 2A first insert block 18 is movably installed on one side of the mounting plate 17. A second slot 28 is opened at one end of the fixing rod 19, and the second slot 28 cooperates with the first insert block 18. A locking block is sleeved on the outside of the first insert block 18, and the locking block is connected to the rotating rod 15 by a belt. By setting the first insert block 18 and the second slot 28, the first insert block 18 can enter the second slot 28 more stably, and there will be no problem of insufficient rotation transmission efficiency. At the same time, the problem of the first insert block 18 being difficult to insert into the second slot 28 is avoided, thus improving the overall working stability.

[0043] Please see Figure 7 An arc-shaped block 9 is provided on one side of the movable rod 8, and a spring 10 is installed at one end of the arc-shaped block 9. A slot that matches the arc-shaped block 9 is opened at one end of the housing 1. The movable rod 8 and the housing 1 are slidably connected. By setting the arc-shaped block 9, the movable rod 8 can be limited by the arc-shaped block 9 after it moves, preventing the movable rod 8 from automatically resetting, ensuring that the water supply system can work normally, and avoiding the problem of water supply system interruption caused by the automatic resetting of the movable rod 8.

[0044] Please see Figure 4 The box 1 is equipped with a water tank 20, and a water pipe 27 is installed on one side of the water tank 20. The box 1 is equipped with a water trough 30, and a mounting groove 31 that cooperates with the water pipe 27 is provided on one side of the water trough 30. A water outlet 29 is provided at one end of the water trough 30. By setting the water trough 30, the water can move along the water trough 30 during the transportation process and will not deviate from the direction of the water flow. At the same time, the water outlet 29 can discharge the water to one side of the carrying plate 13, so that the carrying plate 13 can be cleaned with cleaning fluid during the cleaning process.

[0045] Please see Figure 4 The second steel cable 32 is provided with second pulleys 33 on both sides, and there are multiple sets of second pulleys 33. The outer side of the second pulleys 33 is provided with a slot that matches the second steel cable 32. By setting the second pulleys 33, the movement of the second steel cable 32 can be made more effortless, without generating a large friction force, reducing power consumption, and extending the service life of the second steel cable 32. It can achieve the purpose of moving the mounting plate 17 upward by translating the movable rod 8.

[0046] Please see Figure 3 The movable plate 4 is set in two opposing sets. A pulley 12 is set on one side of the first steel cable 16, and a groove is opened on the outer side of the first pulley 12 to cooperate with the first steel cable 16. Through the arrangement of the movable plate 4 and the first steel cable 16, the friction of the first steel cable 16 can be reduced during the movement, making the movement of the movable plate 4 easier and without consuming too much force.

[0047] Please see Figure 2An electric box 21 is installed on one side of the box 1, and a drive line 2 is installed on one side of the electric box 21. A vibrating head 3 is installed at one end of the drive line 2, and the driving power inside the electric box 21 is transmitted to the vibrating head 3 through the drive line 2. By setting the drive line 2, the power inside the electric box 21 can be transmitted to the vibrating head 3, so that the vibrating head 3 can vibrate, thereby enabling the sputum suction operation to proceed normally.

[0048] Please see Figure 7 One end of the inner rod 5 is equipped with a limiting block 6, and multiple sets of limiting blocks 6 are provided. One end of the carrying plate 13 is provided with a groove that matches the limiting block 6, and the cross-section of the limiting block 6 is triangular. The inner side of the carrying plate 13 is provided with bristles, and one end of the connecting block 24 is equipped with a return spring. By setting the limiting block 6, the limiting block 6 can fit with the carrying plate 13, thereby making the transmission of the inner rod 5 more effective and avoiding the problem that the inner rod rotation 5 is difficult to drive the carrying plate 13 to rotate, thus greatly reducing the cleaning effect of the vibrating head 3.

[0049] The working principle of this invention is as follows: Before using the sputum suction device, the vibrating head 3 is placed under the carrier plate 13. At this time, the inner rod 5 moves down, which drives the outer rod 11 to move down. At this time, the outer rod 11 drives the connecting block 24 to move. When the connecting block 24 moves down, it pulls the first steel cable 16, which causes the slider 23 to move, thereby causing the movable plate 4 to move towards the center. At this time, the movable plate 4 is closed.

[0050] When the inner rod 5 is displaced, the first slot 22 at the end of the inner rod 5 contacts the second insertion block 25, so that the second insertion block 25 is connected to the inner rod 5;

[0051] Furthermore, after the vibrating head 3 is installed, the motor box 26 is started, causing the second insertion block 25 to rotate. When the second insertion block 25 rotates, it drives the inner rod 5 to rotate, thereby causing the carrying plate 13 to rotate. At this time, the carrying plate 13 cleans the vibrating head, wipes off surface stains, and improves work efficiency.

[0052] Furthermore, when the carrier plate 13 rotates, the movable rod 8 is moved, causing the collar 7 to contact the drive line 2, thereby fixing the drive line 2 under the collar 7. When the movable rod 8 moves, the arc-shaped block 9 is first squeezed, and then when the movable rod 8 no longer contacts the arc-shaped block 9, the arc-shaped block 9 is reset under the action of the spring 10, thus the movable rod 8 is limited by the arc-shaped block 9.

[0053] When the movable rod 8 moves, it pulls the second steel cable 32, causing the mounting plate 17 to shift. When the mounting plate 17 shifts, the first insertion block 18 enters the second slot 28 at one end of the fixed rod 19, causing the locking block on the outside of the first insertion block 18 to rotate. Through the belt, the rotating rod 15 rotates. When the rotating rod 15 rotates, it drives the spiral blade 14 to rotate. At this time, the cleaning fluid flows through the water tank 20 into the water pipe 27 under the action of the spiral blade 14, and then enters the outlet through the water trough 30, finally falling into the interior of the carrier plate 13. At this time, the carrier plate 13 rotates, cleaning the vibrating head 3 with the cleaning fluid. This can minimize the risk of cross-infection of bacteria and also eliminate the need to cover the surface of the vibrating head 3 with gauze, enhancing the patient's comfort.

[0054] Furthermore, after cleaning is completed, the motor housing 26 is closed, thereby pulling the movable rod 8 to reset it, which causes the mounting plate 17 to move down. At this time, the spiral blade 14 stops supplying water, and the water inside the carrying plate 13 is discharged through the side hole of the housing 1. The vibrating head 3 is then removed, so that the inner rod 5 is no longer under pressure. Under the action of the reset spring at the end of the connecting block 24, the movable plate 4 moves to both sides, allowing the vibrating head 3 to be removed and used.
