Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of endotracheal tube fixation devices, and in particular relates to an endotracheal tube fixation device. Background Technology
[0002] Endotracheal intubation is a method of inserting a specially designed endotracheal tube through the mouth and glottis into the trachea. 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.
[0003] Once the endotracheal tube is inserted into the trachea, it needs to be secured. Securing it ensures the stability of the tube's position and prevents displacement or dislodgement due to patient movement or changes in posture. Currently, the method for securing the endotracheal tube involves wrapping two strips of adhesive tape across the tube, then attaching the tape to the face to position it. Next, white duct tape is wrapped around the tube for further fixation, and finally, the movable end of the tape is tied to the head for additional security.
[0004] In this process, although the combination of adhesive tape and duct tape makes it easy to fix the endotracheal tube to the patient's face, the duct tape will come into contact with the patient's facial skin during the binding process. Because the duct tape is thin and long, it is easy to form a cord-like shape. Therefore, when the duct tape comes into contact with the patient's facial skin, it is easy to squeeze the patient's face, causing pain and discomfort. Utility Model Content
[0005] The purpose of this invention is to provide a tracheal tube fixation device that reduces the risk of facial compression and pain during the fixation of the tracheal tube.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
[0024] Example 1
[0025] The endotracheal tube fixation device described in this embodiment, such as Figure 1 As shown, it includes a horizontally arranged support tube 1, which is connected front to back; in use, the endotracheal tube 2 in the endotracheal intubation tube is placed in the support tube 1.
[0026] like Figure 1 As shown, a clamping plate 8 is provided on the support tube 1, and the clamping plate 8 is located inside the support tube 1. The support tube 1 has a threaded hole that communicates vertically, and a screw 7, threadedly engaged with the screw, passes through the threaded hole. One end of the screw 7 protrudes from the threaded hole and is located outside the support tube 1, while the other end is rotatably connected to the clamping plate 8. This entire design constitutes a locking assembly for locking the endotracheal tube 2 inside the support tube 1. When the other end of the screw 7 is rotatably connected, a blind hole can be opened at the top of the clamping plate 8, and a bearing can be installed inside the blind hole. The outer ring of the bearing is fixed in the blind hole, and the other end of the screw 7 is fixed to the inner ring of the bearing, thus achieving a rotatable connection. In use, by driving the screw 7 on the outside of the support tube 1 to move up and down in the threaded hole, the clamping plate 8 can be moved up and down. When the clamping plate 8 moves downward and the tracheal tube 2 is located in the support tube 1, the tracheal tube 2 can be clamped in the support tube 1, thus achieving the purpose of locking the tracheal tube 2. When clamping, care should be taken not to clamp the tracheal tube 2 too tightly, so as not to affect the passage of gas inside.
[0027] like Figure 1 As shown, during implementation, the upper end of the screw 7 in the locking assembly can be fixed with a handle 6, and the screw 7 can be moved up and down in the threaded hole more conveniently by operating the handle 6;
[0028] like Figure 1As shown, in a further preferred embodiment, the clamp 8 has a semi-circular structure. Since the endotracheal tube 2 has a tubular structure, the semi-circular clamp 8 can increase the contact area when clamping the endotracheal tube 2, thereby making the endotracheal tube 2 more stably clamped in the support tube 1.
[0029] like Figure 1 and Figure 2 As shown, a retaining ring 5 is fitted onto the support tube 1, and two straps 3 are symmetrically fixed to the retaining ring 5; the inner wall of the retaining ring 5 is fixed to the outer wall of the support tube 1; the two straps 3 are horizontally arranged and located on the left and right sides of the retaining ring 5, with the right end of the left strap 3 fixed to the retaining ring 5 and the left end of the right strap 3 fixed to the retaining ring 5; in use, after the endotracheal tube 2 is locked inside the support tube 1, the two straps 3 are then tied to the patient's head to limit the position of the retaining ring 5, thereby limiting the position of the support tube 1 and the endotracheal tube 2;
[0030] like Figure 1 and Figure 3 As shown, one end of the support tube 1 is connected to a bite tube 14 that is easy for the teeth to bite on. The bite tube 14 is located behind the retaining ring 5 and is horizontally positioned. The front end of the bite tube 14 is fixed to the rear end of the support tube 1. After the support tube 1 and the bite tube 14 are fixed, their interiors are connected, so the endotracheal tube 2 can easily pass through the interiors of the support tube 1 and the bite tube 14. In use, after the endotracheal tube 2 is inserted into the throat from the mouth, the endotracheal tube 2 is passed through the interiors of the support tube 1 and the bite tube 14, and then the bite tube 14 is placed in the patient's mouth. The patient then bites on the bite tube 14 with their teeth. Because the endotracheal tube 2 is located inside the bite tube 14, the problem of the patient unconsciously biting on the endotracheal tube 2 with their teeth during endotracheal intubation, which would lead to obstructed gas delivery, is avoided. Therefore, the design of the bite tube 14 ensures the stability of the endotracheal tube 2 during use.
[0031] like Figure 1 and Figure 2As shown, the strap 3 has mounting strips 4 along its length, and the mounting strips 4 are made of soft material. A soft pad 11 for contact with the patient's facial skin is provided on the mounting strip 4. The mounting strip 4 is located behind the strap 3 and can be made of cotton, sponge, silicone, or rubber. The soft pad 11 is located behind the mounting strip 4 and can be made of sponge or cotton. During use, the soft pad 11 is placed on the patient's face. Because the soft pad 11 is located on the mounting strip 4, and the strap 3 contacts the mounting strip 4, the soft pad 11 replaces the strap 3 in contact with the patient's skin. When the soft pad 11 contacts the patient's skin, it feels more comfortable than direct contact with the strap 3. Therefore, during the fixation of the endotracheal tube 2, the design of the soft pad 11 contacting the patient's facial skin minimizes the problem of the strap 3 squeezing the patient's facial skin, causing pain and discomfort.
[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the soft pad 11 is provided with locking posts 12, and there are several locking posts 12 arranged at equal intervals along the length of the soft pad 11; the soft pad 11 has through holes for the locking posts 12 to pass through; one end of the locking post 12 passes through the through hole and is fixed to the mounting strip 4, and the other end of the locking post 12 is provided with an adhesive 13 for adhering to the face; this section of the solution constitutes a limiting component for limiting the soft pad 11 to the patient's face; the locking posts 12 can be made of silicone material, so the locking posts 12 have a certain degree of hardness and softness; the adhesive 13 can be made of hydrocolloid dressing. The adhesive used can also be the AB adhesive from the breast patch. This type of adhesive is not only easy to tear off, but also leaves no residue on the patient's facial skin and can be reused after washing. Before use, the adhesive 13 has release paper attached to it, which prevents the adhesive 13 from sticking to other objects, thus isolating the adhesive on the adhesive 13. The soft pad 11 and the mounting strip 4 are not fixedly connected during installation. When installing the soft pad 11 onto the mounting strip 4, the through hole of the soft pad 11 is fitted onto the locking post 12 of the mounting strip 4 to secure the position of the soft pad 11. The locking post 12 design allows for easy positioning of the soft pad 11 on the mounting strip 4, and also facilitates its removal for cleaning and disinfection. The presence of multiple locking posts 12 provides a more stable hold on the soft pad 11. During use, the release paper on the adhesive 13 is peeled off, and then the adhesive 13 is brought into contact with the patient's facial skin. Upon contact, the adhesive 13 adheres to the face. Because the adhesive 13 is positioned on the locking post 12, it can effectively hold the pad in place. The locking post 12 is positioned to limit the soft pad 11, which is fixed to the mounting strip 4 and limits its position. This keeps the soft pad 11 in place on the patient's face. The adhesive 13 design prevents the soft pad 11 from falling off the patient's facial skin during use, achieving the purpose of limiting its position. Preferably, the length of the locking post 12 is the same as the thickness of the soft pad 11, or the length of the locking post 12 is slightly longer than the thickness of the soft pad 11. This design avoids the problem of the locking post 12 being too long and affecting the contact between the soft pad 11 and the patient's facial skin.
[0033] In implementation, according to Figure 2 In the position of the locking pin 12 in the limiting component, it can also be in the form of a "T" shape. Because the soft pad 11 is elastic, the through hole on the soft pad 11 can be stretched to be larger and then put on the locking pin 12. After pulling the soft pad 11, the soft pad 11 can rebound through its elasticity and be locked on the locking pin 12. Through the "T" shape design of the locking pin 12, the soft pad 11 can be more stably limited between the mounting strip 4 and the locking pin 12.
[0034] like Figure 1 and Figure 2As shown, the mounting strip 4 has a limiting groove for easy insertion of the strap 3; the limiting groove is opened along the length of the mounting strip 4, and the mounting strip 4 and the strap 3 are in contact with each other. When the strap 3 is tied to the patient's head, its body is placed in the limiting groove on the mounting strip 4, which can limit the position of the strap 3 and make it more stable to cooperate with the mounting strip 4.
[0035] In practical use: After the endotracheal tube 2 is inserted into the patient's trachea, firstly, the support tube 1, retaining ring 5, and bite tube 14 are placed on the endotracheal tube 2. Then, the patient bites down on the bite tube 14. Next, the endotracheal tube 2 is clamped within the support tube 1 using the screw 7 and clamp 8. Then, a soft pad 11 is placed at the point where the bandage 3 contacts the patient's facial skin. The soft pad 11 is adhered to the face by the adhesive 13 on the locking post 12. Then, the bandage 3 is placed in the limiting groove on the mounting strip 4. Finally, the bandage 3 is... The movable end is tied to the patient's head; therefore, after the strap 3 is tied, it can limit the position of the support tube 1, the retaining ring 5 and the biting tube 14, thereby limiting the endotracheal tube 2 in the support tube 1; during use, because the strap 3 is placed on the installation strip 4, which is equipped with a soft pad 11, the soft pad 11 can replace the strap 3 to contact the patient's skin. Therefore, the design of the soft pad 11 directly contacting the patient's skin can make the patient's skin feel comfortable and avoid the problem of facial pain and discomfort as much as possible.
[0036] Example 2
[0037] This embodiment further illustrates the technology, such as Figure 1 , Figure 5 and Figure 6 As shown, the support tube 1, retaining ring 5, and bite tube 14 are all divided into upper and lower halves along their length. The support tube 1, retaining ring 5, and bite tube 14 are evenly divided into upper and lower halves. In use, the two halves of the support tube 1, retaining ring 5, and bite tube 14 are separated, and then the endotracheal tube 2 is placed between the two halves of the support tube 1, retaining ring 5, and bite tube 14. Finally, the two halves of the support tube 1, retaining ring 5, and bite tube 14 are spliced together as a whole. By dividing it into two parts, it is easy to put the support tube 1, retaining ring 5, and bite tube 14 onto the endotracheal tube 2, thus achieving the purpose of convenient installation.
[0038] like Figure 1 , Figure 5 and Figure 6As shown, two limit boxes 9 are symmetrically fixed to the upper half of the support tube 1, and two limit rods 10 in an "n" shape are symmetrically fixed to the lower half of the support tube 1. The limit rods 10 are made of elastic material. Each limit box 9 has a through hole at its bottom, the inner diameter of which is smaller than the width of the limit rod 10. Each limit box 9 has an operating hole on its side wall that communicates with the inside. This section of the design constitutes a fixing assembly for fixing the upper and lower halves of the support tube 1 together. The two limit boxes 9 are arranged left and right, with the left limit box 9 fixed to the left side of the upper half of the support tube 1 and the right limit box 9 fixed to the right side of the upper half of the support tube 1. The limit rods 10 can be made of plastic. Made of the same material; the two limiting rods 10 are also arranged side by side and located directly below the limiting box 9. One end of the left limiting rod 10 is fixed to the left side of the lower half of the support tube 1, and one end of the right limiting rod 10 is fixed to the right side of the lower half of the support tube 1; therefore, the other end of the limiting rod 10 is in a movable state, which facilitates the compression of the limiting rod 10; in use, because the inner diameter of the perforation at the bottom of the limiting box 9 is smaller than the width of the limiting rod 10, the limiting rod 10 cannot enter the limiting box 9 through the perforation in its natural state. However, the limiting rod 10 is elastic, which allows it to be compressed. During the compression process, the limiting rod 10 can be deformed, thereby increasing the width of the limiting rod 10. If the diameter is less than the inner diameter of the perforation, the limiting rod 10 can be inserted into the limiting box 9 through the perforation. After entering the limiting box 9, the limiting rod 10 is not compressed and rebounds, thus locking itself inside the limiting box 9. This achieves the purpose of limiting the limiting rod 10 within the limiting box 9. Because the limiting box 9 and the limiting rod 10 are fixed between the upper and lower halves of the support tube 1, they are fixed together. Since the retaining ring 5 and the biting tube 14 are both fixed to the support tube 1, they can also be limited together. When it is necessary to remove the limiting rod 10 from the limiting box 9, the left side limiting... The operating hole on the positioning box 9 is preferably located on its left side wall, and the operating hole on the right side positioning box 9 is preferably located on its right side wall. The size of the operating hole is designed according to the thickness of a normal finger, so that the finger can pass through the operating hole to squeeze the limiting rod 10 inside the positioning box 9. Therefore, the limiting rod 10 inside the positioning box 9 can be squeezed and deformed. After the limiting rod 10 is squeezed and deformed, its width can be reduced, so that the width of the limiting rod 10 is less than the inner diameter of the through hole on the positioning box 9. Therefore, by pulling the limiting rod 10 downward, the limiting rod 10 can be pulled out from the positioning box 9, thereby realizing the separation between the positioning box 9 and the limiting rod 10, thus achieving the purpose of disassembling the upper and lower halves of the support tube 1.
[0039] In implementation, the fixing component can also be replaced with a latch. There are two sets of latches, which are symmetrically installed between the upper and lower half of the support tube 1. The latch includes a movable part and a fixed part. The movable part of the latch is fixed on the upper half of the support tube 1, and the fixed part of the latch is fixed on the lower half of the support tube 1. Therefore, the upper and lower half of the support tube 1 can be fixed together by the cooperation between the movable part and the fixed part.
[0040] Because the retaining ring 5 is located between the support tube 1 and the bite tube 14, the retaining ring 5 can separate the support tube 1 and the bite tube 14, preventing the patient's mouth from contacting the limiting box 9 during biting and causing discomfort.
