Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an auxiliary tool for airway cleaning in respiratory and critically ill patients. Background Technology

[0002] In the fields of critical care medicine and surgery, suctioning is a key airway management technique, especially in patients with upper airway obstruction caused by coughing and expectoration difficulties. Suctioning requires timely and efficient removal of excess secretions from the airway to quickly restore airway patency.

[0003] The patent application number "CN222130661U" describes a suction tube, including a main tube, a bulbous suction head, and a rigid tube. One end of the main tube is connected to the bulbous suction head, and the rigid tube is fitted onto the main tube. The section of the rigid tube near the bulbous suction head is bent at an obtuse angle. The other end of the main tube is forked, with a suction tube and an irrigation tube connected to it respectively. This invention, by fitting a rigid tube onto the main tube and plastically bending the section of the rigid tube near the bulbous suction head at an obtuse angle, allows the rigid tube to be pushed to the front of the main tube during use. The user can then hold the rear end of the rigid tube and rotate it left and right to adjust and guide the direction of the bulbous suction head located at the front of the rigid tube. The obtuse angle bending structure of the front end of the rigid tube also facilitates insertion into the deep oral cavity for suction. Simultaneously, the suction tube and irrigation tube connected to the forked end of the main tube allow for suction or irrigation as needed.

[0004] Traditional airway cleaning tools typically include a suction catheter and an auxiliary fixation device. However, in practice, patients may experience unstable biting due to impaired consciousness or inability to cooperate, making it difficult to fix the suction catheter and affecting the effectiveness of the procedure. In addition, the fixation structure of existing tools is often quite complex, lacking convenience and comfort, which may increase patient discomfort and even cause damage to the oral mucosa. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary tool for airway cleaning in respiratory and critically ill patients. It aims to solve the problem that traditional airway cleaning tools in the prior art usually include a suction tube and an auxiliary fixation device. However, in actual operation, patients may have unstable bite due to impaired consciousness or inability to cooperate, making it difficult to fix the suction tube and affecting the operation effect. In addition, the fixation structure of existing tools is often relatively complex, lacking convenience and comfort, which may increase the patient's discomfort and even cause damage to the oral mucosa.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0017] As a preferred embodiment of this utility model, the flat-mouth stop block is made of natural rubber.

[0018] As a preferred embodiment of this utility model, an inclined anti-detachment ring is fixedly connected to the circumferential surface of the main tube, and the inclined anti-detachment ring prevents the suction connector from falling off.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. In this design, the combination of the flat-mouth stop and the limiting block allows the patient to stably bite down on the catheter, effectively preventing catheter displacement during suctioning and significantly improving operational accuracy. The flat-mouth stop is made of natural rubber, which has good elasticity and biocompatibility, reducing pressure damage to the patient's oral mucosa.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Please see Figures 1-3 The present invention provides the following technical solution:

[0030] A respiratory and critical care airway cleaning aid includes:

[0031] The two managers, Manager 1 and Deputy Manager 2, are connected.

[0032] Two limiting blocks 9 are fixedly connected to the circumferential surface of the main pipe 1;

[0033] Flat-mouth stop 7, which is fitted onto the circumferential surface of the main pipe 1;

[0034] Two hollow slots 8 are provided on one side of the flat-mouth stop block 7, and two limiting blocks 9 are respectively matched with the two hollow slots 8.

[0035] Suction connector 5 is sleeved on the circumferential surface of the main pipe 1;

[0036] Airbag 3, airbag 3 is fixed to the secondary tube 2.

[0037] In a specific embodiment of this utility model, the main tube 1 and the auxiliary tube 2 are interconnected. The main tube 1 is inserted into the patient's airway for suctioning, and the auxiliary tube 2 is connected to the cuff 3. The limiting block 9 cooperates with the flat nozzle stop 7 to prevent it from sliding. The flat nozzle stop 7 is for the patient to bite and fix it. Its material is preferably natural rubber to improve comfort and anti-slip properties. Two hollow grooves 8 match the limiting block 9 to ensure stable fixation. The limiting block 9 limits the flat nozzle stop 7. At the same time, when the flat nozzle stop 7 is rotated so that the limiting block 9 enters the hollow groove 8, the flat nozzle stop 7 can be removed. In this device, the limiting block 9 protrudes only 5mm to prevent scratching the oral cavity. The suction connector 5 is used to connect to the negative pressure suction device. The cuff 3 can be used for assisted ventilation and can also expel the residue in the main tube 1 after use. The design of the flat mouth stop 7 and the limiting block 9 ensures that the main tube 1 is not easily displaced during suctioning, improving the accuracy of operation. The cooperation between the auxiliary tube 2 and the cuff 3 can realize assisted ventilation, improve the overall efficiency of airway management, facilitate quick installation and use by medical staff, and is suitable for clinical emergencies. Even when personnel cannot cooperate, the stability of the main tube 1 can be maintained.

[0038] Please refer to the details. Figures 1-3 An adjusting ring 10 is fixedly connected to the other end of the flat-mouth stop 7, and both hollow grooves 8 pass through the adjusting ring 10.

[0039] In this embodiment: the rotational position of the flat nozzle block 7 on the main pipe 1 is adjusted by adjusting the adjusting ring 10 to prevent cross-infection and prevent the flat nozzle block 7 from being contaminated with bacteria.

[0040] Please refer to the details. Figures 1-3 The upper end of the suction connector 5 is provided with a gasket 6, and the gasket 6 is directly connected to the suction connector 5 through a rope.

[0041] In this embodiment: when the negative pressure suction device is connected, the pad 6 can increase the contact area and reduce the risk of the connector becoming loose due to patient movement or vibration during operation. Even if the suction connector 5 becomes loose accidentally, the rope connection can prevent it from falling off completely, avoiding contamination or loss.

[0042] Please refer to the details. Figures 1-3 A sealing cap 4 is fitted onto the circumferential surface of the secondary pipe 2.

[0043] In this embodiment: when the secondary tube 2 is not used for assisted ventilation or drug administration, the sealing cap 4 can close the tube opening to prevent external contaminants from entering the airway. In mechanical ventilation mode, it can ensure that the airflow only passes through the main tube 1, thereby improving ventilation efficiency. The sealing cap 4 can be opened and closed quickly, which is suitable for scenarios where the secondary tube 2 needs to be used intermittently.

[0044] Please refer to the details. Figures 1-3 The flat-mouth stopper 7 is made of natural rubber.

[0045] In this embodiment: natural rubber is soft and elastic, reducing the pressure on the patient's mouth when biting, avoiding damage to the gums or mucosa. The surface friction of natural rubber is moderate, preventing the stop from slipping due to the patient's unconscious movements. The material is resistant to disinfectant corrosion and is suitable for repeated use.

[0046] Please refer to the details. Figures 1-3 An inclined anti-detachment ring 11 is fixedly connected to the circumferential surface of the main pipe 1, and the inclined anti-detachment ring 11 prevents the suction connector 5 from falling off.

[0047] In this embodiment, the tilting anti-detachment ring 11 restricts the axial movement of the suction connector 5 by physical blocking, preventing it from slipping off the main pipe 1, without the need for additional fixing devices.

[0048] The working principle and usage process of this utility model are as follows: The flat nozzle block 7 is slid along the main tube 1 so that the limiting block 9 is inserted into the hollow groove 8. Then, it is rotated to return to the centered state. The patient bites on the flat nozzle block 7, which provides comfortable support using the flexibility of its natural rubber, while preventing the main tube 1 from shifting left or right. The suction connector 5 is connected to the negative pressure suction device. The gasket 6 can prevent accidental dislodgement. The cooperative design of the flat nozzle block 7 and the limiting block 9 ensures that the main tube 1 is not easily displaced during sputum suction, improving the accuracy of operation. The cooperation between the auxiliary tube 2 and the cuff 3 can realize assisted ventilation, improve the overall efficiency of airway management, and facilitate quick installation and use by medical staff.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
