Description

Technical Field

[0001] This utility model relates to the field of endotracheal intubation technology, specifically to a endotracheal intubation sealing device. Background Technology

[0002] Endotracheal intubation is a method of inserting a specially designed endotracheal tube through the mouth or nose and into the trachea or bronchus via the glottis. It provides optimal conditions for airway patency, ventilation and oxygen supply, and airway suction, and is an important measure for rescuing patients with respiratory dysfunction. When the patient's condition improves and the endotracheal tube needs to be removed, the endotracheal tube is sealed. However, the outer diameter of the sealing structure used for existing endotracheal tubes is fixed, making it difficult to achieve an adjustable function. This makes it inconvenient for staff to apply the sealing structure to endotracheal tubes with different inner diameters, greatly reducing the applicability of the sealing structure. Utility Model Content

[0011] Preferably, the outer shell, threaded rod, transmission block, conical block, and top block are all made of stainless steel.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a endotracheal intubation occlusion device, which has the following beneficial effects:

[0014] 1. This endotracheal tube sealing device, by controlling the transmission block to drive the threaded rod to rotate clockwise, can drive the conical block to move downward, so that the conical block can drive the top block to move outward, so that the top block can push the rubber sleeve outward, so that the rubber sleeve is slowly supported and opened, increasing the outer diameter of the rubber sleeve. It realizes the adjustable function, making it convenient for staff to apply this device to endotracheal tubes with different inner diameters, greatly improving the applicability of the device.

[0015] 2. This endotracheal tube sealing device, through the design of anti-slip texture, can increase the friction between the operator's fingers and the transmission block, preventing slippage when the transmission block is turned. At the same time, as the limiting rod slides along the inside of the limiting groove, it can effectively limit the moving top block, ensuring the stability of the top block when it moves.

[0016] 3. The endotracheal tube sealing device, through the setting of the glue tank, allows the operator to firmly stick the top and bottom of the rubber sleeve to the inner wall of the outer shell, ensuring the fixation effect between the rubber sleeve and the outer shell and preventing the rubber sleeve from falling off. At the same time, due to the setting of the limiting hole, it can prevent the cone block from moving downward excessively, causing the cone block to detach from the contact with the top block.

[0023] 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.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a endotracheal intubation sealing device, including a shell 1, a rubber sleeve 2 fitted on the inner wall of the shell 1, a threaded rod 3 penetrating through the upper surface of the shell 1, the threaded rod 3 being threadedly connected to the shell 1, a transmission block 4 being fixedly connected to the top end of the threaded rod 3, a conical block 5 being fixedly connected to the bottom end of the threaded rod 3, a through groove 6 being opened on the inner wall of the shell 1, the through groove 6 communicating with the interior of the shell 1, a top block 7 being slidably connected inside the through groove 6, and the inner side of the top block 7 being in movable contact with the outer surface of the conical block 5.

[0025] By controlling the transmission block 4 to drive the threaded rod 3 to rotate clockwise, the conical block 5 can be moved downwards, which in turn drives the top block 7 to move outwards. This allows the top block 7 to push against the rubber sleeve 2 outwards, thus slowly supporting the rubber sleeve 2 and increasing its outer diameter. This achieves an adjustable function, making it convenient for staff to apply the device to various endotracheal tubes with different inner diameters, greatly improving the device's applicability.

[0026] By setting the anti-slip texture 9, the friction between the operator's fingers and the transmission block 4 can be increased, preventing slippage when the transmission block 4 is turned. At the same time, as the limit rod 11 slides along the inside of the limit groove 10, the moving top block 7 can be effectively limited, ensuring the stability of the top block 7 when it moves.

[0027] The glue tank 8 allows workers to firmly attach the top and bottom of the rubber sleeve 2 to the inner wall of the outer shell 1, ensuring the fixation between the rubber sleeve 2 and the outer shell 1 and preventing the rubber sleeve 2 from falling off. At the same time, the limiting hole 12 prevents the cone block 5 from moving downwards excessively, thus preventing the cone block 5 from detaching from the top block 7.

[0028] The dimensions and shapes of all components in this structure are not specifically limited here and need to be produced according to the actual situation.

[0029] To prevent the rubber sleeve 2 from falling off during use, this invention provides glue grooves 8 at the top and bottom of the inner wall of the outer shell 1. There are two sets of glue grooves 8. By injecting glue into the glue grooves 8, the top and bottom of the rubber sleeve 2 can be firmly adhered to the inner wall of the outer shell 1, improving the fixing effect between the outer shell 1 and the rubber sleeve 2 and preventing the rubber sleeve 2 from falling off during use.

[0030] To prevent the operator's fingers from slipping when turning the transmission block 4, this invention provides anti-slip texture 9 on the outer surface of the transmission block 4. The anti-slip texture 9 increases the friction between the transmission block 4 and the operator's fingers, thus preventing the operator's fingers from slipping when turning the transmission block 4.

[0031] In order to ensure the stability of the top block 7 during movement, this utility model provides a limiting groove 10 in the middle of the inner wall of the bottom of the through groove 6. A limiting rod 11 is slidably connected inside the limiting groove 10. The upper surface of the limiting rod 11 is fixed to the lower surface of the top block 7. As the limiting rod 11 slides along the inside of the limiting groove, the moving top block 7 can be effectively limited, thus ensuring the stability of the top block 7 during movement.

[0032] In order to prevent the conical block 5 from moving downwards excessively, this utility model provides a limiting hole 12 in the middle of the bottom inner wall of the outer shell 1. When the bottom end of the conical block 5 is inserted into the limiting hole 12, the limiting hole 12 can block it, thus preventing the conical block 5 from moving downwards excessively and causing the conical block 5 to detach from contact with the top block 7.

[0033] In order to extend the service life of the outer shell 1, threaded rod 3, transmission block 4, conical block 5, and top block 7, this utility model uses stainless steel as the material for all of these components. Stainless steel has high hardness, is not easily deformed, and is not easily rusted, thus extending the service life of the outer shell 1, threaded rod 3, transmission block 4, conical block 5, and top block 7.

[0034] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0035] Before use, the operator fills the glue tank 8 with glue, then places the rubber sleeve 2 onto the inner wall of the outer shell 1. Due to the glue, the top and bottom of the rubber sleeve 2 are firmly adhered to the inner wall of the outer shell 1, allowing the inner wall of the rubber sleeve 2 to contact the outer surface of the top block 7. Once the glue has solidified, the device is ready for use. The operator holds the transmission block 4 and inserts the outer shell 1 into one end of the endotracheal tube. When the outer diameter of the outer shell 1 is smaller than the inner diameter of the endotracheal tube, the operator controls the transmission block 4 to rotate clockwise. During this process, the anti-slip texture 9 provides an anti-slip function. Simultaneously, the transmission block 4 drives the threaded rod 3 to rotate clockwise along the inside of the outer shell 1. Because the threaded rod 3 and the outer shell 1 are connected by a thread... The threaded connection allows the threaded rod 3 to rotate clockwise, causing the conical block 5 to move downwards. As the conical block 5 moves downwards, it pushes the top block 7 outwards, causing the top block 7 to move the limiting rod 11 outwards along the inside of the limiting groove 10. This causes the top block 7 to slowly push the rubber sleeve 2 outwards, gradually supporting the middle of the rubber sleeve 2 until the outer surface of the rubber sleeve 2 is tightly attached to the inner wall of the endotracheal tube. Then, the screwing of the transmission block 4 stops. Because the threaded rod 3 is threadedly connected to the outer shell 1, it can achieve a self-locking function for the conical block 5, indirectly ensuring that the outer surface of the middle part of the rubber sleeve 2 is firmly attached to the inner wall of the endotracheal tube. Thus, the sealing of the endotracheal tube is completed.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
