Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a pollution-resistant respiratory secretion clearer. Background Technology

[0002] Suctioning devices mainly include electric multi-functional negative pressure suction devices and simple manual suction devices. The operating end needs to be connected to a suction tube or sponge suction tube to be used. Electric suction devices are more commonly used, with both a power switch and a manual switch. They utilize the principle of negative pressure for suctioning and oral care, and are simple and easy to learn.

[0003] A search of Chinese patents revealed a suction device (publication number CN220632664U). However, this secretion remover lacks a protective function. Generally, these devices use a handle to move a piston, creating negative pressure to suction out secretions. However, controlling the force when moving the handle is difficult; excessive force can cause strong suction, potentially injuring the airway and harming the patient. This makes them inconvenient to use and lacks support. Furthermore, the suction tube is inserted into the patient's mouth, causing discomfort and potentially leading to the patient biting the tube, deforming or damaging it. The collection bottle is also difficult to assemble and disassemble; after suctioning, it needs to be removed for cleaning. Since the collection screen is typically threaded, repeated rotation is required during assembly and disassembly, making the process cumbersome, increasing workload, and reducing efficiency. To address these problems, we propose a contamination-resistant respiratory secretion remover. Utility Model Content

[0004] The purpose of this invention is to provide a pollution-proof respiratory secretion clearer, which has the advantages of having a protective function, a supporting function, and easy assembly and disassembly of the collection bottle.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a pollution-proof respiratory secretion clearer, comprising a housing, a suction mechanism disposed inside the housing, a fixed tube connected to the top of the housing, a first fixed frame bolted to the inner wall of the fixed tube, a screw rotatably sleeved on the inner wall of the first fixed frame, a second fixed frame slidably connected to the inner wall of the fixed tube, and the second fixed frame being threadedly connected to the surface of the screw, a limit ring fixedly sleeved on the inner wall of the fixed tube, a blocking plate penetrating the surface of the screw, and a first spring fixedly connected between the blocking plate and the second fixed frame by a spring fixing member, and the first spring being sleeved on the surface of the screw.

[0006] By adopting the above technical solution, if the suction force is greater than the elastic force of the first spring during the cleaning process, the blocking plate will drop, allowing gas to enter the housing. The suction force is kept constant, which can achieve the purpose of protection, avoid respiratory tract damage, and improve safety. The suction force can be adjusted by rotating the screw by rotating the rotating head, making it convenient to use.

During the clearing process, if the suction force is greater than the elastic force of the first spring 9, the blocking plate 8 will drop, allowing gas to enter the housing 1. By maintaining a constant suction force, the device can achieve the purpose of protection, avoid respiratory tract damage, and improve safety. The suction force can be adjusted by rotating the rotating head 29 to rotate the screw 5, making it convenient to use.

[0030] refer to Figure 2 The suction mechanism 2 includes a piston 25, which is slidably sleeved with the inner wall of the housing 1. A T-shaped rod 26 is rotatably connected to the surface of the piston 25.

A third spring 33 is fixedly connected between the piston 25 and the inner wall of the handle 27 by a spring fixing member, and the third spring 33 is sleeved on the surface of the T-shaped rod 26. A one-way valve 28 is connected to the surface of the handle 27. By setting up the suction mechanism 2, moving the T-shaped rod 26 causes the piston 25 to move. The movement of the piston 25 creates a negative pressure inside the housing 1, which suctions out the secretions for easy cleaning.

[0031] refer to Figure 1 and Figure 4 A rotating head 29 is bolted to the top of the screw 5, which facilitates the rotation of the screw 5.

[0032] refer to Figure 4 The inner wall of the blocking plate 8 is provided with a sealing ring 30 to prevent air leakage.

[0033] Example 2: refer to Figure 1 , Figure 2 and Figure 5A guide tube 10 is fixedly sleeved on the inner wall of the housing 1. A connecting tube 11 is connected to the surface of the housing 1. The other end of the connecting tube 11 is connected to a suction tube 12. A slip ring 13 is provided through the surface of the suction tube 12. A fixing rod 14 is bolted to the surface of the slip ring 13. A telescopic rod 15 is slidably sleeved on the inner wall of the fixing rod 14. An adjusting bolt 16 is threadedly connected to the inner wall of the fixing rod 14. A support plate 17 is bolted to one end of the telescopic rod 15.

This achieves the purpose of providing support, avoids damage to the suction tube 12, and improves practicality. By loosening the adjusting bolt 16, it can be adjusted according to the size of the patient's oral cavity, which improves applicability.

[0034] refer to Figure 2 The surface of the housing 1 is threadedly connected to the connecting pipe 11. By setting the surface of the housing 1 to be threadedly connected to the connecting pipe 11, disassembly and maintenance are facilitated.

[0035] refer to Figure 1 and Figure 5 A silicone pad 31 is bonded to the surface of the support plate 17. By setting the silicone pad 31, damage to the patient's teeth can be prevented.

[0036] Example 3: refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 The bottom of the housing 1 is connected to a fixed cylinder 18. A collection bottle 19 is slidably sleeved on the inner wall of the fixed cylinder 18. A rotating cylinder 20 is rotatably sleeved on the surface of the fixed cylinder 18. A connecting rod 21 is hinged to the inner wall of the rotating cylinder 20. A snap-fit ​​connector 22 is hinged to the other end of the connecting rod 21.

A snap-fit ​​groove 24 is opened on the surface of the collection bottle 19, and the snap-fit ​​connector 22 snaps into the snap-fit ​​groove 24. By rotating the rotating cylinder 20, the connecting rod 21 drives the snap-fit ​​connector 22 to move. The movement of the snap-fit ​​connector 22 causes the snap-fit ​​connector 22 to disengage from the snap-fit ​​groove 24, thus removing the collection bottle 19. This method can facilitate the installation and removal of the collection bottle 19, reduce the workload, and improve work efficiency.

[0037] refer to Figure 6 One end of the clip connector 22 is wedge-shaped, which facilitates the fixing of the collection bottle 19.

[0038] refer to Figure 3 The surface of the rotating cylinder 20 is provided with anti-slip texture 32. By setting the anti-slip texture 32, the hand slips and the operation is facilitated.

[0039] Brief description of usage: During the cleaning process, if the suction force exceeds the elastic force of the first spring 9, the blocking plate 8 will descend, allowing gas to enter the housing 1, thus maintaining a constant suction force. Rotating the rotating head 29 causes the screw 5 to rotate, which in turn moves the second fixing bracket 6. This movement of the second fixing bracket 6 changes the elastic force of the first spring 9, thus changing the maximum suction force. This allows adjustment of the suction force, achieving a protective function. Placing the support plate 17 between the patient's teeth provides support to the oral cavity, achieving a support function. Loosening the adjusting bolt 16 allows the support plate 17 to be moved to the desired position, and then tightening the adjusting bolt 16 allows for adjustment of the suction force. Adjustable according to the size of the patient's oral cavity to improve applicability; rotate the rotating cylinder 20, which drives the connecting rod 21 to move, and the connecting rod 21 to move the snap-fit ​​connector 22, so that the snap-fit ​​connector 22 disengages from the snap-fit ​​groove 24, and the collection bottle 19 is removed, completing the disassembly. During installation, the collection bottle 19 is inserted into the fixing cylinder 18, and the snap-fit ​​connector 22 engages with the snap-fit ​​groove 24 under the action of the second spring 23, fixing the collection bottle 19 and completing the installation, thereby achieving the purpose of easy installation. By setting the guide tube 10, the secretions are directly guided into the collection bottle 19, avoiding contact between the secretions and the piston 25 and the housing 1, thereby preventing the secretions from contaminating the piston 25 and the housing 1, and facilitating later maintenance.
