Abstract
Description
Technical Field
[0001] This invention relates to the field of suction devices, and in particular to an auxiliary suction device for the care of critically ill patients. Background Technology
[0002] A suction device is a medical device used to help critically ill patients clear respiratory secretions. It uses mechanical suction to remove sputum, blood, or other foreign objects from the patient's airway, maintaining airway patency and preventing complications such as suffocation and lung infections. Critically ill patients often experience respiratory secretion retention due to impaired consciousness, weak cough, or swallowing difficulties. Suction devices can promptly remove these secretions, preventing airway obstruction. They reduce the time secretions remain in the airway, lowering the risk of bacterial growth and infection. They also ensure proper oxygen and carbon dioxide exchange, improving the patient's respiratory efficiency.
[0003] However, existing suction devices typically only have a sputum reservoir, with one side connected to the suction tube and the other side directly connected to the suction device via a flexible tube. This means that during use, sputum may enter the suction device through the flexible tube, making it difficult to clean the inside of the device easily. Over time, this can lead to contamination of the suction device's interior. Therefore, an auxiliary suction device for the care of critically ill patients is proposed. Summary of the Invention
[0004] To overcome the shortcomings of existing technologies, this invention proposes an auxiliary suction device for the care of critically ill patients. It can set up a negative pressure container between the sputum reservoir and the suction device, which significantly reduces the possibility of the suctioned sputum entering the suction device, making it easier to ensure the cleanliness of the suction device. At the same time, it can also facilitate the disinfection and cleaning of the negative pressure container.

[0017] The beneficial effects of this invention are:
[0018] 1. The technical solution of the present invention adds a negative pressure cylinder between the sputum storage container and the suction device. In this way, the sputum storage container is connected to the negative pressure cylinder, and the negative pressure cylinder is indirectly connected to the suction device.

[0019] 2. The technical solution of the present invention uses a telescopic component to drive the pallet to move upward, thereby causing the can cover and the card seat to move upward, and then the card seat to abut against the inner wall of the machine box, causing the can cover to move downward relative to the negative pressure cylinder, thereby clamping and sealing the negative pressure cylinder. At the same time, a sealing component is used to perform a second seal between the can cover and the negative pressure cylinder to achieve an effective sealing effect.
[0020] 3. The technical solution of the present invention uses the telescopic component to drive the tray to move down until the sealing cover seals the opening. During the process, when the limiting block abuts against the top frame, it can drive the can lid to slide away from the negative pressure cylinder in the machine box. At the same time, the downward movement of the tray will also drive the linkage component to pull the upper sliding seats on both sides and the nozzles closer to each other. Then, the nozzles on both sides move to the top of the negative pressure cylinder and the negative pressure tube head respectively, so as to facilitate the spraying of cleaning and disinfection agent on both for cleaning and disinfection. It can also clean the surface of the suction can through the cleaning component. Attached Figure Description

[0032] The following will be combined with the appendix Figure 1 To be continued Figure 9 The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0033] Example 1:
[0034] like Figure 1-9As shown, the present invention discloses an auxiliary suction device for the care of critically ill patients, including a suction device 1, a housing 2 with an opening 4 at the top connected to the front end of the suction device 1, a pressurizing and heating module 3 installed on one side of the housing 2, a sputum storage tank 6 provided on one side of the housing 2, a telescopic component 7 connected inside the housing 2, and a support plate 8 connected to the output end of the telescopic component 7, a sealing cover 10 for covering the opening 4 connected above the support plate 8, a negative pressure tube head 11 installed on one side of the upper end face of the support plate 8, a negative pressure cylinder 13 provided on the other side, a can cover 17 slidably connected to the support plate 8, and a sealing sleeve between the can cover 17 and the upper end of the negative pressure cylinder 13;
[0035] Among them, the suction device 1 is an existing mature device, while the pressurization and heating module 3 is also an existing mature device used to pressurize and heat the inside of the casing 2 to achieve high temperature and high pressure for disinfection and sterilization.
[0036] The inner wall of the can lid 17 is provided with a sealing component, which is used to seal the negative pressure cylinder 13 and the can lid 17. The bottom of the housing 2 is connected to a top frame 34 that fits onto the tray 8. The can lid 17 is connected to a limiting block 32 that abuts against the upper end of the top frame 34. A cleaning component is provided inside the top frame 34, which is used to clean the negative pressure cylinder 13. The inner walls on both sides of the housing 2 are also slidably connected to upper slide seats 28. Each upper slide seat 28 has a nozzle 31 installed at its lower end. The housing 2 is also provided with a linkage component, which is used to drive the nozzles 31 on both sides to move closer to each other when the tray 8 moves down, so as to spray cleaning disinfectant onto the negative pressure cylinder 13 and the negative pressure pipe head 11 for cleaning.
[0037] The upper end of the casing 2 is connected to a threaded cylinder 5. The lower outer side of the sputum collection container 6 is threaded into the threaded cylinder 5. The upper end of the tray 8 is connected to an electric threaded seat 12. The lower outer side of the negative pressure cylinder 13 is threaded into the electric threaded seat 12. This facilitates the flexible installation of the sputum collection container 6 and the upper surface of the casing 2. It also facilitates the installation of the negative pressure cylinder 13 on the tray 8 through the electric threaded seat 12, and it can also rotate under the drive of the electric threaded seat 12.
[0038] The upper end of the tray 8 is connected to the connecting frame 9, and the sealing cover 10 is connected to the upper end of the connecting frame 9. The upper end of the sputum collection container 6 and the lid 17 are both connected to the air inlet pipe 18 and the air outlet pipe 19. The air inlet pipe 18 on the sputum collection container 6 is connected to the suction tube. The air outlet pipe 19 on the sputum collection container 6 and the air inlet pipe 18 on the lid 17, as well as the air outlet pipe 19 on the lid 17 and the negative pressure tube head 11 are all connected to the flexible tube. The sputum collection container 6, the suction tube and the flexible tube are usually disposable.
[0039] The connection between the sputum collection container 6 and the negative pressure cylinder 13, as well as between the negative pressure cylinder 13 and the negative pressure tube head 11, is facilitated. The addition of the negative pressure cylinder 13 allows the suction device 1 to significantly prevent sputum from entering the suction device 1 when it is suctioning the patient's sputum, thus ensuring that the suction device 1 still maintains a high level of cleanliness after multiple uses.
[0040] Example 2:
[0041] like Figure 1-9 As shown, the present invention discloses an auxiliary suction device for the care of critically ill patients. Compared with Embodiment 1, this embodiment discloses the structure of the sealing component.
[0042] The sealing assembly includes a retainer 15, an annular sealing groove 20, an annular platform 21, and an annular rubber ring 22. The retainer 15 is connected to both sides of the tank cover 17, and the lower end of the retainer 15 abuts against the inner wall of the casing 2 along the inner edge of the opening 4. The annular sealing groove 20 is opened inside the tank cover 17 and is sealed with the upper end of the negative pressure cylinder 13. The annular platform 21 is connected to the upper end of the inner wall of the negative pressure cylinder 13. The annular rubber ring 22 is connected inside the tank cover 17, and the lower end of the annular rubber ring 22 is connected to a top ring 23 that abuts against the upper end of the annular platform 21. The annular rubber ring 22 fits against the inner wall of the negative pressure cylinder 13. The annular platform 21, the annular rubber ring 22, and the top ring 23 are all located inside the annular sealing groove 20.
[0043] When the tray 8 moves upward until one side of the card holder 15 contacts the inner wall of the casing 2 along the inner edge of the opening 4, the card holder 15 will pull the can cover 17 closer to the negative pressure cylinder 13, thus achieving a seal between the can cover 17 and the negative pressure cylinder 13. Furthermore, the sealing area can be increased by fitting the annular sealing groove 20 onto the upper end of the negative pressure cylinder 13, thereby improving the sealing performance.
[0044] Furthermore, when the can lid 17 slides closer to the negative pressure cylinder 13, it will also cause the top ring 23 to abut against the upper end of the annular platform 21 on the inner wall of the negative pressure cylinder 13. This will cause the middle part of the annular rubber ring 22 connecting the top ring 23 and the can lid 17 to bulge outward and make interference contact with the inner wall of the negative pressure cylinder 13, thus achieving a second seal between the can lid 17 and the negative pressure cylinder 13, further improving the sealing effect between the negative pressure cylinder 13 and the can lid 17.
[0045] Both sides of the tray 8 are connected to slide rods 14. The lower end of the card seat 15 on both sides is also slidably sleeved on the surface of the slide rod 14. A spring 16 is sleeved on the surface of the slide rod 14 between the upper end of the slide rod 14 and the lower end of the card seat 15. The setting of the spring 16 enables the can lid 17 to have a basic pushing force to move closer to the negative pressure cylinder 13, so that the can lid 17 can fit and cover the upper end of the negative pressure cylinder 13.
[0046] Example 3:
[0047] like Figure 1-9 As shown, this invention discloses an auxiliary suction device for the care of critically ill patients. Compared with Embodiment 2, this embodiment discloses the structure of the linkage component.
[0048] The linkage components include a sliding base 25 and a rotating plate 30. There are two sliding bases 25, which are slidably connected to the two sides of the lower inner wall of the chassis 2 respectively. One end of the rotating plate 30 is rotatably connected to the sliding base 25, and the other end is rotatably connected to the adjacent upper sliding base 28.
[0049] The inner walls of the left and right sides of the chassis 2 are connected to slide rod brackets 27. The upper slide seat 28 is slidably sleeved on the outside of the slide rod bracket 27. The upper slide seat 28 and the inner wall of the chassis 2 are connected by a spring 3 29 sleeved on the outside of the slide rod bracket 27. The bottom sides of the chassis 2 are connected to slide rod brackets 1 24. The lower slide seat 25 is slidably sleeved on the outside of the slide rod bracket 1 24. The lower slide seat 25 and the bottom of the chassis 2 are connected by a spring 26 sleeved on the outside of the slide rod bracket 1 24.
[0050] After use, the telescopic component 7 can be used to move the tray 8 downwards until the sealing cap 10 seals the opening 4. During this process, the limiting block 32 connected to the can lid 17 will abut against the upper end of the top frame 34. Subsequently, as the tray 8 continues to move downwards, the negative pressure cylinder 13 will separate from the can lid 17. That is, the card seat 15 will slide upwards relative to the surface of the slide rod 14 and compress the spring 16, creating a gap between the negative pressure cylinder 13 and the can lid 17. As the tray 8 continues to move downwards, its two sides will abut against the sliding seats 25 on both sides, driving... The sliding seat 25 slides down and compresses the second spring 26, which in turn pulls the rotating plate 30 to rotate, causing the upper sliding seats 28 on both sides to slide closer to each other and compress the third spring 29. At the same time, it also drives the nozzles 31 on the upper sliding seats 28 on both sides to slide directly above the negative pressure cylinder 13 and the negative pressure pipe head 11, so as to spray cleaning and disinfecting agents on them. Then, the pressurized heating module 3 can pressurize and heat the inside of the machine box 2 to achieve sterilization and disinfection of the negative pressure cylinder 13, the can lid 17 and the negative pressure pipe head 11 under high pressure and high temperature.
[0051] Example 4:
[0052] like Figure 1-9 As shown, the present invention discloses an auxiliary suction device for the care of critically ill patients. Compared with Embodiment 3, this embodiment discloses the structure of the cleaning component.
[0053] The cleaning components include a slide opening 33, a slide groove 35, a slide plate 37, and a cleaning brush 39. The slide opening 33 is opened on the tray 8, and the tray 8 is slidably fitted on the outer side of the top frame 34 through the slide opening 33. The slide groove 35 is opened on the side of the top frame 34 near the negative pressure cylinder 13. The slide plate 37 is trapezoidal and is slidably connected in the slide groove 35. The slide plate 37 is in contact with the inner wall of the slide opening 33 and slides against it. The cleaning brush 39 is installed on the slide plate 37 and slides in the slide opening 33.
[0054] The upper and lower inner walls of the slide groove 35 are connected to slide rod brackets 36. The upper and lower ends of the slide plate 37 are respectively slidably sleeved on the outside of the slide rod brackets 36. A spring 4 38 sleeved on the outside of the slide rod brackets 36 connects the slide plate 37 and the inner wall of the slide groove 35.
[0055] This allows the tray 8 to slide down the surface of the top frame 34 through the slide opening 33, first making contact with and sliding against both ends of the slide plate 37, squeezing the slide plate 37 into the slide groove 35, and compressing the spring 4 38. After the tray 8 passes through the slide groove 35, the slide plate 37 bounces up under the action of the spring 4 38, and the cleaning brush 39 on it comes into contact with the surface of the negative pressure cylinder 13. With the rotation of the electric threaded seat 12, the surface of the negative pressure cylinder 13 is cleaned.
[0056] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
