Disposable simple trachea cannula fixer

Abstract

This invention provides a disposable, simple endotracheal intubation fixator for use in the field of endotracheal intubation. It includes a fixation tube with an adjusting sleeve and a threaded bolt connected to its inner wall. A knob drives the threaded bolt to press and adjust the adjusting sleeve, thereby fixing and locking the intubation tube to prevent slippage, displacement, and dislodgement. It employs a biomimetic integrated dental arch design, consisting of upper and lower occlusal plates and an elastic arc strip, preventing occlusal force from directly acting on the intubation tube and dispersing the biting force. Buffer pads are provided on the occlusal plates for cushioning and protection. Suction cups are added to the cheekbone area on both sides of the patient, connected to the fixation tube via an arc-shaped fixation frame. The bony support of the cheekbone reduces stress on facial soft tissues. Non-woven fabric patches are placed on the skin-contacting surfaces of the suction cups to keep the skin dry and clean. Elastic bands are incorporated into the arc-shaped fixation frame for double fixation, making it compatible with the needs of different patient groups and clinical scenarios.

Description

Technical Field

[0001] This application relates to the field of endotracheal tube fixation, and in particular to a disposable, simple endotracheal tube fixation device. Background Technology

[0002] Endotracheal tube fixators are medical devices primarily used to secure endotracheal tubes during surgery or examinations, preventing them from shifting or dislodging to ensure a clear airway for the patient. Some endotracheal tube fixators are designed for single use to reduce the risk of cross-infection.

[0003] Currently, endotracheal tubes are mostly secured in clinical practice using tape or crisscrossing ropes. However, this method is complex, inefficient, and time-consuming for clinical medical staff, especially in the intensive care unit where workload is heavy and time is extremely precious. Furthermore, tape fixation can lead to numerous complications: skin damage, insecure adhesion causing tube dislodgement, and its applicability is limited to dry skin. Oily skin and patients with excessive sweating require frequent tape changes. Due to concerns about patients biting the tube, mouthguards are sometimes used, but these are made of hard material and can easily cause gum bleeding, and in severe cases, tooth loss.

[0004] In view of the above-mentioned prior art, the technical problem to be solved by this application is to improve the efficiency of oral care for intubated patients in the intensive care unit, make the fixation or replacement of fixation simple and convenient, improve work efficiency, reduce the time spent on oral care for intubated patients, reduce complications caused by fixation in intubated patients, and expand the scope of application. Utility Model Content

[0005] The purpose of this application is to provide a disposable, simple endotracheal intubation fixation device compared to existing technologies, which is suitable for people with different physical conditions, is easy and quick to operate, and reduces skin and oral complications caused by fixation.

[0006] The endotracheal tube fixation device of this application includes a fixation tube, one end of which is fixedly connected to an upper bite plate and a lower bite plate. The upper bite plate and the lower bite plate are fixedly connected by elastic arc strips on both sides.

[0007] Next, a sleeve is fitted onto the inner wall of the fixed tube near the biting plate. An adjusting sleeve is fixedly connected to one side of the sleeve. The adjusting sleeve is a retractable flat-topped cone. An insertion tube is slidably connected to the inner wall of the smaller diameter end of the adjusting sleeve. A beveled structure is provided on the outer wall of the larger diameter end of the adjusting sleeve. A threaded bolt is threadedly connected to the inner wall of the fixed tube away from the sleeve. A beveled structure is provided on the inner wall of one end of the threaded bolt. The inner wall of the threaded bolt is slidably connected to the outer wall of the adjusting sleeve through the beveled structure. An adjusting knob is fixedly connected to the end of the threaded bolt away from the adjusting sleeve.

[0008] A collar is fitted onto the outer wall of the fixed tube near the adjusting knob. A connecting plate is fixedly connected above the collar. Arc-shaped fixing frames are fixedly connected to both sides above the connecting plate. A suction cup is fixedly connected to the back of the arc-shaped fixing frame away from the connecting plate. A belt ring is snapped onto the top of the arc-shaped fixing frame away from the connecting plate. An elastic belt is fitted onto the belt ring.

[0009] Furthermore, cushioning pads are provided on the upper surface of the upper occlusal plate and the lower surface of the lower occlusal plate.

[0010] The cushioning pad is made of memory foam.

[0011] Furthermore, a non-woven fabric patch is adhered to the front of the suction cup.

[0012] Furthermore, the suction cup is fixedly connected to the connecting plate via elastic shape memory alloy wires inside the arc-shaped fixing frame.

[0013] Furthermore, the upper and lower bite plates are made of silicone material through compression molding.

[0014] Except for the upper and lower bite plates, the components are made of soft PVC injection molding.

[0015] Furthermore, the flat-top cone surface of the adjusting sleeve is provided with annular anti-slip texture.

[0016] The wall thickness of the adjusting sleeve is 0.8-1.2 mm.

[0017] The inner wall of the threaded bolt is coated with polytetrafluoroethylene.

[0018] The inner wall of the collar (11) is provided with an array of anti-slip protrusions.

[0019] Compared to existing technologies, the advantages of this application are as follows:

[0020] (1) This application uses an adjustment knob to drive the displacement of the threaded bolt. The threaded bolt and the adjusting sleeve are engaged in a bevel process to form a ring pressure on the insertion tube, thereby fixing the insertion tube. At the same time, the outward tension of the adjusting sleeve locks the threaded bolt, making it difficult for the insertion tube to slide, shift, or come out. The structure is simple and the operation is convenient and quick.

[0021] (2) The bionic dental arch integrated design is adopted. The upper and lower occlusal plates fit the upper and lower jaw teeth, disperse the biting force, and avoid the force on a single tooth. The occlusal plates are equipped with buffer pads, which, combined with the elastic arc strips, form a gradient hardness, providing buffering and good soft tissue wrapping for biting. At the same time, the biting force does not directly act on the cannula, providing a good protection mechanism for cannulation.

[0022] (3) An arc-shaped fixing frame is added. The suction cup is adjusted to adhere to the skin of the cheekbone area through the arc-shaped fixing frame. The bony support of the cheekbone reduces the stress on the facial soft tissue. At the same time, the elasticity and plasticity of the arc-shaped fixing frame allow the suction cup to adapt to the height difference of the cheekbone. The non-woven fabric patch on the contact surface between the suction cup and the skin can absorb sweat and meet the protection requirements. An elastic band is set to provide double fixation, which combines stability and comfort while making it easy to release the fixation.

[0023] (4) The instruments are made of soft PVC injection molding and silicone compression molding, which has low production cost, simple process, and high degradability, meeting the economic and sustainability requirements of disposable products. Attached Figure Description

[0032] Example 1

[0033] This utility model provides a disposable, simple endotracheal tube fixation device. Please refer to [link / reference]. Figure 3 , Figure 4 and Figure 5The device includes a fixed tube 1, which has a fixed cavity inside. An adjusting sleeve 5 is fitted onto one side of the inner wall of the fixed cavity via a sleeve seat 4. The adjusting sleeve 5 is a flat-topped conical shape with four adjusting flaps. The outer surface of the adjusting flaps has a beveled structure. The inner wall of the end of the fixed tube 1 away from the sleeve seat 4 is threadedly connected to the outer wall of the threaded bolt 3. The inner wall of the end of the threaded bolt 3 near the adjusting sleeve 5 has a beveled structure. The threaded bolt 3 and the adjusting sleeve 5 are slidably connected through the mutually fitting beveled structures. An adjusting knob 2 is also fixed on the other side of the threaded bolt 3.

[0034] In the implementation of this solution, the insertion tube 6 is inserted through the adjusting knob 2, passing through the oral cavity of the fixator. The position, angle, and depth of the insertion tube 6 are adjusted. The adjusting knob 2 is then turned counterclockwise. The threaded bolt 3 moves towards the adjusting sleeve 5 through the threaded transmission with the inner wall of the fixing tube 1. The adjusting valve structure on the adjusting sleeve 5 is compressed and retracts towards the axis, thereby clamping and fixing the insertion tube 6. The clamping force on the insertion tube 6 is a ring pressure, which is not easy to slip, shift, or dislodge, and has strong stability. In addition, since the adjusting valve has outward tension in the contracted state, it compresses the threaded bolt 3 outward to achieve automatic locking. The structure is simple, and the operation of fixing or replacing the insertion tube 6 is convenient and quick, improving work efficiency.

[0035] Please see Figure 1 and Figure 2 The upper occlusal plate 7 and the lower occlusal plate 8 are fixedly connected at one end of the fixed tube 1 near the patient's oral cavity. The two ends of the upper occlusal plate 7 and the lower occlusal plate 8 are fixedly connected by an elastic arc strip 9. The contact surfaces of the upper occlusal plate 7 and the lower occlusal plate 8 with the patient's teeth are covered with a cushioning pad 10, which is made of memory foam.

[0036] During endotracheal intubation 6, patients may experience tooth fracture or occlusion of the endotracheal tube 6 due to restlessness or unconscious biting during the anesthesia recovery period. In this embodiment, the fixator adopts a biomimetic dental arch design. The upper occlusal plate 7 and lower occlusal plate 8 conform to the upper and lower jaw dentition, distributing the biting force to the entire dental arch structure and avoiding force on individual teeth. The occlusal plates are made of soft and durable medical-grade silicone material, possessing sufficient strength and good biocompatibility. The cushioning pad 10 on the contact surface between the teeth and the occlusal plates is made of memory foam material, which can adapt to shape and form a gradient hardness with the occlusal plates, providing cushioning and soft tissue coverage for biting.

[0037] The arc strip 9 provides resistance to occlusion while maintaining the integrity of the dental arch design. In addition, the integrated design of the dental arch components and the fixing tube 1 prevents the dental pad from falling off, and the occlusal force does not directly act on the insertion tube 6, providing a good protection mechanism for the insertion tube 6.

[0038] Please see Figure 1 , Figure 2 and Figure 3A collar 11 is fitted onto the outer wall of the fixed tube 1 near the adjusting knob 2. The arc-shaped fixing frame 13 located on both sides of the connecting plate 12 is integrated with the fixed tube 1 through the collar 11. An elastic alloy wire is set inside the arc-shaped fixing frame 13. The arc-shaped fixing frame 13 is fixedly connected to the suction cup 14 through the alloy wire. A non-woven fabric patch 15 is bonded to the contact surface between the suction cup 14 and the patient's skin. A belt ring 16 is snapped onto the end of the arc-shaped fixing frame 13. An elastic band 17 is fitted on the belt ring 16.

[0039] In the implementation of this application, the suction cup 14 is attached to the skin of the cheekbone area, utilizing the bony support of the cheekbone to reduce the stress on the facial soft tissue. The elastic alloy wire inside the arc-shaped fixation frame 13 has good elasticity and plasticity, which can adapt to the height difference of the cheekbone, and can also absorb the instantaneous pulling force when coughing or agitated. The suction cup 14 can avoid skin irritation or damage caused by traditional adhesives. The non-woven fabric patch 15 on the skin contact surface of the suction cup 14 is highly soft and has good water absorption, which can both absorb sweat and meet the protection requirements, keeping the local skin dry and clean, making the suction cup 14 less likely to fall off. The two elastic bands 17 are adjustable in length, which can connect the fixation device to the ear loop, and can also loop around the head to form a double fixation, which is compatible with the needs of different patient groups and clinical scenarios, and combines stability and comfort while making it easy to remove the fixation.

[0040] In this embodiment, most of the components of the fixator are made of soft PVC injection molding, such as the fixation tube 1, connecting plate 12 and adjusting sleeve 5. The biting plate and suction cup 14 are made of medical-grade silicone material by compression molding. The production cost is low, the process is simple, and the biodegradability is high, which meets the economic and sustainability requirements of disposable products.

[0041] The above description is only the best implementation method adopted in this application in combination with current practical needs, but the scope of protection of this application is not limited thereto.
