Description

Technical Field

[0001] The utility model belongs to the field of medical technology, and in particular relates to a fixing device for nasotracheal intubation and gastric tube. Background Art

[0002] The nasotracheal tube and gastric tube fixation device is an important tool used in medical care to ensure the stability and safety of the endotracheal tube and gastric tube. The nasotracheal tube fixation device is a device used to firmly fix the endotracheal tube in the patient's nasal cavity. This device is crucial for patients who require long-term or short-term respiratory support and can ensure the patency and stability of the airway.

[0003] For example, the authorization announcement number is CN219049954U, an integrated multifunctional nasotracheal intubation fixing device. This patent disclosure can fix the tracheal tube and the gastric tube through the intubation fixing adjustment mechanism to prevent the distance between the tracheal tube and the gastric tube from being too large, causing bending and kinking, and the distance being too small, causing blockage of the pipeline and affecting use.

[0004] The disclosed patent design aims to stabilize the nasotracheal tube or gastric tube through a specific tube fixing sleeve. However, in actual application, due to the possible size mismatch between the tube and the fixing sleeve, it is often difficult to achieve the ideal stabilization effect after direct insertion.

[0005] Specifically, when the cannula fixing sleeve is placed on the patient and attempted to be inserted into the preset cannula fixing sleeve, due to the slight size difference between the two, even a slight external disturbance or the patient's own movement may cause the cannula to shake inside the cannula fixing sleeve. This shaking will not only reduce the fixation effect, but may also be directly transmitted to the patient's body through the cannula in the trachea, causing discomfort to the patient and even affecting the safety and effectiveness of the treatment. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4 The utility model provides the following technical solutions: a fixing device for nasotracheal intubation and gastric tube, comprising a fixing head cover 1, one side of the fixing head cover 1 is connected to a fixing belt 2, two intubation fixing sleeves 3 are installed on the fixing belt 2, and a connecting rod 4 is arranged at the upper end of the intubation fixing sleeve 3; when in use, the patient puts the fixing head cover 1 on the head, and then inserts the nasotracheal or gastric tube to be used into the corresponding intubation fixing sleeve 3. When the nasotracheal intubation is needed, the adjusting sleeve 5 on one of the intubation fixing sleeves 3 needs to be adjusted toward the nostril, and then the nasotracheal intubation is inserted into the patient's nostril through the adjusting sleeve 5, thereby completing the corresponding intubation operation.

[0022] Four connecting rods 4 are provided, and two connecting rods 4 are symmetrically provided on each cannula fixing sleeve 3. The tops of the corresponding two connecting rods 4 are connected to the bottom of the adjusting sleeve 5. A top ring 6 is bonded to the top of the adjusting sleeve 5, and the inner diameter of the top ring 6 is smaller than the inner diameter of the adjusting sleeve 5.

[0023] Preferably: a limiting ring 51 is fixedly installed on the inner wall of the adjusting sleeve 5 near the bottom opening, a tightening block 52 is arranged between the surface of the limiting ring 51 and the bottom of the top ring 6, an elliptical through groove is penetrated through the center end of the tightening block 52, and the tightening block 52 and the adjusting sleeve 5 are made of deformable hard rubber material.

[0024] During specific use, when the operator needs to pass the nasotracheal or gastric tube cannula through the inside of the adjusting sleeve 5, the operator first squeezes the adjusting sleeve 5 toward the center end, so that the elliptical through hole at the center end of the adjusting sleeve 5 opens, and the nasotracheal or gastric tube cannula can smoothly pass through the inside of the adjusting sleeve 5. After the operation is completed, the operator releases the squeezing of the adjusting sleeve 5, and the adjusting sleeve 5 will be reset. In this way, the adjusting sleeve 5 can clamp the nasotracheal or gastric tube cannula, so that the nasotracheal or gastric tube cannula can be fixed on the fixed head cover 1 through the adjusting sleeve 5 during use; preferably: a side plate 31 is fixedly embedded on both sides of the cannula fixing sleeve 3, and a connecting bolt 32 is installed through the top end of the side plate 31, and one end of the connecting bolt 32 is fixedly connected to a threaded column 321, and an outer ring 322 is fixedly sleeved on the outer wall of the connecting end of the connecting bolt 32 and the threaded column 321.

[0025] When it is necessary to perform nasotracheal intubation on the patient, the connecting bolts 32 on both sides of the corresponding intubation fixing sleeve 3 are first adjusted outward, so that the threaded column 321 will be disengaged from the threaded hole 42, so that the connecting rod 4 can be rotated. When in use, the adjusting sleeve 5 can be driven to rotate by adjusting the angle of the connecting rod 4. When one end of the adjusting sleeve 5 is adjusted to be opposite to the patient's nostril, the connecting bolts 32 are tightened again, and the nasotracheal intubation can be fixed by the adjusting sleeve 5, thereby completing the corresponding nasotracheal intubation operation.

[0026] Preferably: an inner cavity 41 is opened inside the connecting rod 4, one end of the inner cavity 41 is connected to a threaded hole 42, the threaded hole 42 is opened inside the connecting rod 4, and the other end of the inner cavity 41 opens to the outside of the connecting rod 4, the threaded column 321 and the threaded hole 42 are threadedly connected, the outer ring 322 is located in the inner cavity 41, and the outer wall of the outer ring 322 is in contact with the inner wall of the inner cavity 41.

[0027] First, the operator needs to evenly squeeze the adjusting sleeve 5 from the edge positions on both sides toward the center position, so as to temporarily change the internal structure of the adjusting sleeve 5 and prepare for the subsequent insertion of the gastric tube.

[0028] Next, the operator needs to carefully insert the gastric tube cannula to be used from the top position of the top ring 6 into the inside of the adjustment sleeve 5. As the gastric tube cannula continues to go deeper, it will pass through the inside of the cannula fixing sleeve 3 and finally be inserted into the patient's trachea.

[0029] After the gastric tube is successfully inserted into the patient's trachea, the operator can release the squeezing of the adjustment sleeve 5. At this time, due to the elastic recovery ability of the adjustment sleeve 5 itself, it will gradually return to its original shape and size. In this process, the tightening block 52 inside the adjustment sleeve 5 will play a key role. The contraction force of the tightening block 52 after clamping will not excessively squeeze and deform the gastric tube, thereby ensuring the normal use of the gastric tube. They will tightly clamp the gastric tube, thereby ensuring its stability and safety during the treatment process.

[0030] In this way, the adjustment sleeve 5 can effectively prevent the gastric tube near the oral cavity from shaking or falling off during the patient's treatment. This not only helps to improve the patient's treatment experience, but also ensures the accuracy and reliability of the treatment effect. Therefore, this operation step is of great significance in practical applications.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
