Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, specifically to a fixation device suitable for preventing the nasal oxygen tube from dislodging after ear surgery. Background Technology
[0002] After ear surgery, oxygen inhalation has become a routine procedure after general anesthesia to promote postoperative recovery and improve tissue hypoxia.
[0003] Traditional methods of fixing nasal oxygen tubes have many problems. Because patients have wounds on their ears after ear surgery, they need to be bandaged with gauze or apply dressings after surgery. The ear loop fixation strap of ordinary nasal oxygen tubes cannot be suspended on the ear. When using adhesive tape for fixation, the oxygen tube often falls off when the patient turns over or moves, requiring repeated patching and affecting the oxygenation effect. In addition, the taped tube can also compress the ear wound or pull up the dressing, aggravating the patient's pain and even affecting wound healing. Summary of the Invention
[0004] The present invention aims to provide a fixation device suitable for preventing the nasal oxygen tube from dislodging after ear surgery, in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: A fixation device for preventing nasal oxygen cannula dislodgement after ear surgery includes an oxygen delivery main pipe connected to a nasal cannula, an oxygen inhalation head connected to the nasal cannula, a connector connected to the oxygen delivery main pipe, an oxygen connector connected to the connector, a fixation component connected to the oxygen delivery main pipe, a bracket connected to the fixation component, a fixation strap and an extension strap connected to the bracket, an adjustment sleeve 1 and an adjustment sleeve 2 detachably connected to the adjustment sleeve 1 and adjustment sleeve 2 respectively connected to a retaining seat, the fixation strap and extension strap passing through the corresponding retaining seat, and an adjustment ring detachably connected to the adjustment sleeve 1 and adjustment sleeve 2 together, the adjustment ring having a retaining hole through which the fixation strap and extension strap pass.
[0006] Preferably, the first adjusting sleeve and the second adjusting sleeve are respectively connected with buckles, the adjusting ring has a slot, the buckles and the slot cooperate with each other, the side wall of the slot is connected to a limiting plate, and the buckles and the limiting plate cooperate with each other.
[0007] Preferably, the fixing strap and the extension strap are made of shape memory alloy braided rope. Preferably, the fixing strap and the extension strap are coated with a skin-friendly silicone coating.
[0008] Preferably, a corrugated pipe section is provided between the oxygen supply main pipe and the fixing component.
[0009] The beneficial effects of this technical solution compared to existing technologies are as follows: (1) This solution uses a fixed strap, an extension strap, an adjustment sleeve 1, an adjustment sleeve 2, and an adjustment ring to make the length adjustment of the fixed strap and extension strap simple and quick. Medical staff can quickly adjust them according to the patient's actual situation to meet the individual needs of different patients. The detachable connection design facilitates the installation, disassembly, cleaning, and disinfection of the device, improving the efficiency of nursing work, and also makes it easy to replace damaged parts, reducing maintenance costs. Through the cooperation of buckles, slots, and limiting plates, the fixed strap and extension strap are firmly locked, preventing the nasal oxygen tube from shifting or falling off due to the patient's movement, turning over, etc., ensuring the continuity and effectiveness of oxygen therapy, and ensuring a stable oxygen supply during the patient's recovery process. In addition, it can prevent the fixed device from directly compressing the wound, reducing the risk of wound bleeding and infection, alleviating the patient's pain, and helping the wound heal.
[0010] (2) The fixing and extension straps are made of shape memory alloy braided rope coated with a skin-friendly silicone coating. The shape memory alloy braided rope is made of shape memory alloy wire mixed with other flexible fibers. The shape memory alloy wire gives it a unique shape memory function, which can restore its initial shape even if it undergoes large deformation within a certain temperature range. It also has good strength and toughness. It can automatically adjust its shape according to the patient's head shape and head circumference, providing a stable and appropriate fixing force, and is not prone to being too tight or too loose. The shape memory function allows the fixing and extension straps to maintain good fixing performance after multiple uses and adjustments, resulting in a long service life. The skin-friendly silicone coating has a low coefficient of friction when in contact with the skin, reducing irritation and pressure on the patient's skin, and improving the tensile strength of the fixing and extension straps, ensuring stability during long-term use.
[0011] (3) By setting the corrugated pipe section, it has good flexibility and bending resistance, can withstand repeated bending without breaking, can adapt to various angles of the patient's head movement, prevent the oxygen delivery pipeline from leaking or breaking due to frequent bending, ensure the stability and safety of oxygen delivery, and extend the service life of the device.

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments: like Figure 1-3 The device shown is a fixation device for preventing nasal oxygen cannula dislodgement during postoperative ear surgery. It includes two main oxygen delivery pipes 3, both connected to a nasal cannula 7. The nasal cannula 7 is connected to an oxygen inhalation head 6. Both main pipes 3 are connected to a connector 1, which is connected to an oxygen connector 2, precisely delivering oxygen to the patient's nasal cavity. Oxygen flows from the oxygen connector 2 through the connector 1 to the two main oxygen delivery pipes 3, then converges back into the nasal cannula 7, and finally enters the patient's nasal cavity through the oxygen inhalation head 6. The dual oxygen delivery pipe design increases the oxygen delivery volume, ensuring the patient receives an adequate oxygen supply. Furthermore, even if one main oxygen delivery pipe 3 malfunctions (such as becoming blocked), the other can still maintain basic oxygen needs, improving the device's reliability. Two oxygen delivery pipes 3 are each connected to a fixing member 4. Each fixing member 4 is connected to a bracket 5. Each bracket 5 is connected to a fixing strap 8 and an extension strap 12. The fixing strap 8 and extension strap 12 are detachably connected to an adjusting sleeve 1 9 and an adjusting sleeve 2 11. Each adjusting sleeve 1 9 and adjusting sleeve 2 11 is connected to a retainer 13. The fixing strap 8 and extension strap 12 pass through their respective retainers 13. The adjusting sleeve 1 9 and adjusting sleeve 2 11 are detachably connected to an adjusting ring 10. The adjusting ring 10 has two locking holes 17, through which the fixing strap 8 and extension strap 12 pass. Medical personnel can adjust the length of the fixing strap 8 and extension strap 12 by rotating the adjusting ring 10 according to the patient's head shape and circumference. When the adjusting ring 10 rotates, the relative position of the locking holes 17 with the fixing strap 8 and extension strap 12 changes, causing the fixing strap 8 and extension strap 12 to rotate and lock inside the adjusting ring 10, achieving initial fixation.
[0014] like Figure 2 , 3 As shown, adjustment sleeve 1 (9) and adjustment sleeve 2 (11) are each connected to three buckles (16). The adjustment ring 10 has a slot (14), and the three buckles (16) engage with the slot (14). Three limiting plates (15) are connected to the sidewall of the slot (14), and the three buckles (16) engage with their corresponding limiting plates (15). Upon initial fixation, the buckles (16) on adjustment sleeve 1 (9) and adjustment sleeve 2 (11) are inserted into the slot (14) of the adjustment ring 10 and engage with the limiting plates (15), further locking the fixing strap 8 and extension strap 12 to prevent loosening. This ensures the fixation device remains stable during patient movement, preventing the nasal cannula from dislodging.
[0015] like Figure 1As shown, the fixing strap 8 and extension strap 12 are made of shape memory alloy braided rope. Both the fixing strap 8 and extension strap 12 are coated with a skin-friendly silicone coating. The shape memory alloy wire gives the fixing strap 8 and extension strap 12 shape memory function, automatically adjusting their shape according to the patient's head shape and circumference, providing stable and appropriate fixation force. The skin-friendly silicone coating is soft, with a low coefficient of friction when in contact with the skin, reducing irritation and pressure on the patient's skin. It also has good breathability and anti-allergy properties, suitable for the sensitive skin of patients after ear surgery. A corrugated section is provided between the main oxygen supply pipe 3 and the fixing component 4. The corrugated section has good flexibility and bending resistance. During patient head movement, the corrugated section can bend freely to adapt to various angles of movement, preventing air leakage and damage to the oxygen supply pipe due to frequent bending, ensuring the stability and safety of oxygen delivery, and extending the service life of the device.
[0016] The specific implementation process is as follows: In use, connect oxygen connector 2 to the external oxygen supply equipment. Based on the patient's head shape and circumference, medical personnel begin adjusting the fixation device. First, rotate the adjusting ring 10 to ensure the relative positions of the locking hole 17 with the fixation strap 8 and extension strap 12 are easily adjustable. Then, pull the fixation strap 8 and extension strap 12 through the corresponding locking seat 13 and locking hole 17, adjusting their length to comfortably wrap around the patient's head and avoid the ear wound. After adjusting to the appropriate length, rotate the adjusting ring 10 again to lock the fixation strap 8 and extension strap 12 inside the adjusting ring 10, achieving initial fixation. After initial fixation, align the three buckles 16 on the adjusting sleeve 1 9 and adjusting sleeve 2 11 with the locking groove 14 of the adjusting ring 10 and insert them. Simultaneously, the buckles 16 cooperate with the limiting plate 15 on the side wall of the locking groove 14 to further lock the fixation strap 8 and extension strap 12, preventing loosening and ensuring the fixation device is securely fixed to the patient's head.
[0017] Then, the external oxygen supply equipment is turned on. Oxygen flows from oxygen connector 2 through connector 1 to two oxygen delivery pipes 3. During the transmission process in the oxygen delivery pipes 3, even if one of the oxygen delivery pipes 3 is blocked or malfunctions, the other pipe can still maintain the basic oxygen needs. The oxygen in the two oxygen delivery pipes 3 eventually merges into the nasal cannula 7. The oxygen is then accurately delivered to the oxygen inhalation head 6 through the nasal cannula 7, and then the oxygen inhalation head 6 delivers the oxygen into the patient's nasal cavity to provide the patient with a sufficient oxygen supply.
[0018] After the patient finishes oxygen therapy, the medical staff first turn off the external oxygen supply equipment, then remove the oxygen inhalation head 6 from the patient's nasal cavity; next, rotate the adjusting ring 10 to separate the buckle 16 from the slot 14, loosen the locking state of the fixing strap 8 and the extension strap 12, then remove the fixing device from the patient's head, and finally disassemble the nasal cannula 7, the oxygen delivery main tube 3 and other components in sequence.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention.
