Description

Technical Field

[0001] This utility model belongs to the field of medical devices, specifically a device for fixing endotracheal intubation catheters. Background Technology

[0002] The endotracheal tube is mainly used to insert into the trachea through the patient's mouth and glottis to ensure airway patency, provide ventilation and oxygen supply, perform airway suction, and prevent aspiration. It plays a crucial role in cardiopulmonary resuscitation and the rescue of critically ill patients with respiratory dysfunction (endotracheal tube, hereinafter referred to as endotracheal tube).

[0003] During endotracheal intubation, a bite block is typically used to secure the endotracheal tube after insertion to prevent it from dislodging or being blocked or damaged by the patient's teeth. Ordinary endotracheal tubes can be difficult to maneuver during intubation; the more critical the patient's condition and the longer the procedure, the greater the risk. Furthermore, after insertion, an assistant is needed to place the bite block, but ordinary bite blocks are often not suitable for the patient's mouth shape and may result in unstable tube fixation, further increasing the risks associated with the procedure.

[0004] To address the problems raised in the background art, those skilled in the art have proposed a device for fixing endotracheal intubation tubes. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a device for fixing endotracheal tubes, thereby resolving issues such as inconvenient operation and easy dislodgement of endotracheal tubes in the prior art.

[0006] An endotracheal tube fixation device includes: an endotracheal tube for maintaining airway patency; a protective mechanism disposed on the endotracheal tube for endotracheal tube bite protection; a limiting mechanism fixedly disposed on the endotracheal tube for limiting and fixing the endotracheal tube; a connecting mechanism fixedly disposed at one end of the endotracheal tube for connecting the endotracheal tube; an adjusting mechanism rotatably disposed on the protective mechanism for adjusting the angle of the endotracheal tube; and a fixing mechanism connected to the adjusting mechanism for auxiliary fixation of the endotracheal tube.

[0007] Preferably, the protective mechanism includes a threaded connecting tube integrally formed on the tracheal tube, and a bite pad sleeve is screwed onto the tracheal tube through the threaded connecting tube, and a sleeve wing is fixedly provided on the bite pad sleeve.

[0008] Preferably, the dental pad sleeve is composed of a combination of sections A and B, and sections A and B on the dental pad sleeve are divided by the sleeve wings.

[0009] Preferably, the limiting mechanism includes a cuff fixedly disposed at one end of the endotracheal tube; a high-pressure tube is fixedly disposed on the endotracheal tube, and the high-pressure tube is connected to the cuff.

[0010] Preferably, an indicator airbag is fixedly installed at one end of the high-pressure pipe, and a valve is fixedly installed on the high-pressure pipe through the indicator airbag.

[0011] Preferably, the connecting mechanism includes a connector fixedly disposed at one end of the endotracheal tube.

[0012] Preferably, the adjustment mechanism includes a connecting thread integrally formed on section B of the dental pad sleeve. The dental pad sleeve is screwed onto a fixing nut one via the connecting thread. A rotating shaft is rotatably mounted on the fixing nut one. A threaded shaft is rotatably mounted on the fixing nut one via the rotating shaft. Fixing nuts two are screwed onto both sides of the outer wall of the threaded shaft. An adjustment limit block is fixedly mounted on the end of the threaded shaft opposite to the rotating shaft.

[0013] Preferably, the fixing mechanism includes a fixing cover connected to the endotracheal tube, with Velcro straps fixedly installed on both sides of the side wall of the fixing cover, and a plurality of latex pads fixedly installed on the inner wall of the fixing cover; an adjustment frame is fixedly installed on one side of the side wall of the fixing cover, and the adjustment limit block can be slidably installed in the adjustment frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention features a bite pad sleeve screwed onto the endotracheal tube via a threaded connecting tube. This allows the endotracheal tube to be easily connected to the bite pad sleeve and cannula wings, making it suitable for patients of various body types and mouth shapes. Therefore, a separate bite pad is not required, saving on medical consumable costs. Simultaneously, the patient's teeth bite into segment A of the bite pad sleeve, which is then fixed and restrained by the cannula wings on the bite pad sleeve. This not only prevents the endotracheal tube from falling out during use but also prevents damage to the endotracheal tube during biting. Combined with the high-pressure tubing and cuff for restraint, this effectively shortens the time required for endotracheal tube intubation, facilitating single-person operation and achieving the goal of convenient endotracheal tube use.

Detailed Implementation

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] Example 1:

[0026] As attached Figure 1 To be continued Figure 6 As shown:

[0027] This utility model provides a device for fixing an endotracheal tube, comprising: an endotracheal tube 1 for maintaining an open airway; a protective mechanism disposed on the endotracheal tube 1 for bite protection; a limiting mechanism fixedly disposed on the endotracheal tube 1 for limiting and fixing the endotracheal tube 1; a connecting mechanism fixedly disposed at one end of the endotracheal tube 1 for connecting the endotracheal tube 1; an adjusting mechanism rotatably disposed on the protective mechanism for adjusting the angle of the endotracheal tube 1; and a fixing mechanism connected to the adjusting mechanism for auxiliary fixing of the endotracheal tube 1.

[0028] By screwing a bite pad cannula 4 onto the endotracheal tube 1 via a threaded connecting tube 7, the endotracheal tube 1 can be easily connected to the bite pad cannula 4 and the cannula wings 5, making it suitable for patients of various body types and mouth shapes. Therefore, a separate bite pad is not required, saving medical consumable costs. At the same time, the patient's teeth bite into segment A on the bite pad cannula 4, and the cannula wings 5 ​​on the bite pad cannula 4 limit and fix it, which not only prevents the endotracheal tube 1 from falling off during use, but also prevents damage to the endotracheal tube 1 during bite. When used in conjunction with the high-pressure tube 3 and the cuff 2 for limiting use, the intubation time of the endotracheal tube 1 is effectively shortened, making it convenient for single-person operation of the endotracheal tube 1 and achieving the goal of convenient use of the endotracheal tube 1.

[0029] refer to Figure 2 and Figure 3 The protective mechanism includes a threaded connecting pipe 7, a toothed sleeve 4, and a sleeve wing 5;

[0030] By integrally forming a threaded connecting tube 7 on the endotracheal tube 1, the endotracheal tube 1 can be easily screwed onto the bite pad sleeve 4 through the threaded connecting tube 7. Thus, for patients of different body types, the position of the bite pad sleeve 4 can be conveniently adjusted by screwing onto the threaded connecting tube 7 according to the patient's mouth shape. Moreover, the thread has self-locking properties, which can fix the position of the bite pad sleeve 4 after it has been screwed onto and adjusted.

[0031] Meanwhile, a threaded connecting tube 7 is fixedly connected to the bite pad sleeve 4, allowing the bite pad sleeve 4 to be divided into two parts, A and B, by the sleeve wings 5. During the use of the endotracheal tube 1, the endotracheal tube 1 is inserted into the patient's trachea through the patient's mouth and glottis. Then, the bite pad sleeve 4 is screwed onto the threaded connecting tube 7 to the position where the patient's teeth bite, so that the patient's teeth bite into section A. The sleeve wings 5 ​​limit the position of the patient's teeth bite. This not only prevents the endotracheal tube 1 from being damaged by the patient's teeth by the bite pad sleeve 4, but also protects and limits the position of the patient's teeth by the sleeve wings 5, preventing the endotracheal tube 1 from falling out.

[0032] Example 2:

[0033] refer to Figure 2 and Figure 4 The limiting mechanism includes a sleeve 2, an indicator airbag 9, and a valve 8;

[0034] By fixing a cuff 2 to one end of the endotracheal tube 1, the cuff 2 can be inflated to fix the front end of the endotracheal tube 1, so as to facilitate the use of the endotracheal tube 1 for limiting and fixing. A high-pressure tube 3 is fixedly connected to the endotracheal tube 1 and connected to the cuff 2, so that the cuff 2 can be inflated through the high-pressure tube 3.

[0035] Meanwhile, an indicator airbag 9 is fixedly connected to one end of the high-pressure tube 3, and a valve 8 is fixedly connected to the indicator airbag 9, so that the high-pressure tube 3 can be fixedly connected to the syringe through the valve 8, and the syringe can be used to inflate the inside of the sheath 2 through the valve 8 and the high-pressure tube 3. When the high-pressure tube 3 inflates the sheath 2, the air pressure of the sheath 2 can be determined by pressing the indicator airbag 9 and observing the hardness of the indicator airbag 9.

[0036] refer to Figure 1 The connecting mechanism includes connector 6;

[0037] By fixing a connector 6 to one end of the endotracheal tube 1 away from the cuff 2, the endotracheal tube 1 can be connected to the ventilator and the breathing bag through the connector 6 when it is in use, thus facilitating the connection and use of the endotracheal tube 1.

[0038] Example 3:

[0039] refer to Figure 1 , Figure 2 and Figure 3 The adjustment mechanism includes a fixing nut 13, a threaded shaft 15, and an adjustment limit block 17;

[0040] By integrally forming a connecting thread 19 on the dental pad sleeve 4B section, the dental pad sleeve 4 can be easily screwed onto a fixing nut 13 via the connecting thread 19. The fixing nut 13 is a hollow structure. When screwed onto the dental pad sleeve 4B section, the endotracheal tube 1 can pass through the inside of the fixing nut 13. A rotating shaft 14 is rotatably connected to the fixing nut 13, so that the fixing nut 13 is rotatably connected to a threaded shaft 15 via the rotating shaft 14. Thus, the threaded shaft 15 can be rotated on the outer wall of the endotracheal tube 1 to adjust the angle of use.

[0041] Meanwhile, fixing nuts 16 are screwed onto both sides of the outer wall of the threaded shaft 15, and an adjusting limit block 17 is fixedly connected to the end of the threaded shaft 15 away from the rotating shaft 14. This allows the threaded shaft 15 to be screwed onto the fixing nut 13 after the rotating shaft 14 is rotated to adjust the operating angle. The fixing nut 16 can be screwed onto the fixing nut 13 to fix the operating angle of the threaded shaft 15. The adjusting limit block 17 can slide on the adjusting frame 11 to adjust the operating position. After the operating position of the adjusting limit block 17 is adjusted by sliding, the fixing nut 16 can be screwed onto the side wall of the adjusting frame 11 to fix the operating position of the threaded shaft 15.

[0042] refer to Figure 1 , Figure 5 and Figure 6 The fixing mechanism includes a fixing cover 10, an adjusting bracket 11, and a Velcro strap 12;

[0043] By connecting a fixed shield 10 to the endotracheal tube 1, the fixed shield 10 can be placed over the patient's face during treatment. Several latex pads 18 are fixedly connected to the inner wall of the fixed shield 10, so that when the fixed shield 10 is placed over the patient's face, the several latex pads 18 support the patient's forehead and cheeks (without contacting the eyes), thereby facilitating the raising of the fixed shield 10 to the height of the patient's face. Furthermore, Velcro straps 12 are fixedly connected to both sides of the fixed shield 10, so that the fixed shield 10 can be easily attached and secured according to the size of the patient's head using the two Velcro straps 12 during use.

[0044] Meanwhile, an adjustment frame 11 is fixedly connected to one side of the fixed cover 10, so that the adjustment limiting block 17 at one end of the threaded shaft 15 can be limited and slidably connected to the adjustment frame 11. Thus, when the endotracheal tube 1 is in use, the threaded shaft 15 can slide on the adjustment frame 11 to adjust the position of use through the adjustment limiting block 17. Then, the angle of use can be adjusted by rotating the shaft 14. Finally, it can be fixed by screwing on the two fixing nuts 16. This makes it easier for the bite pad sleeve 4 to adapt to patients with different mouth shapes for biting, so as to facilitate the use of the endotracheal tube 1.

[0045] Secondly, the fixing shield 10 is made of silicone soft pad material, which makes it easy to fix to the patient's face without causing too much discomfort to the patient. The fixing shield 10 has an oval-shaped hole, which allows medical staff to observe changes in the patient's pupils during treatment. The fixing shield 10 also has a U-shaped groove, which allows the patient's nose to be limited through the U-shaped groove when the fixing shield 10 is in use.

[0046] Working principle: A threaded connecting tube 7 is integrally formed on the endotracheal tube 1, allowing for easy connection of the bite pad sleeve 4 via the threaded connecting tube 7. This allows for convenient adjustment of the bite pad sleeve 4's position according to the patient's mouth shape, tailored to different body types. The threaded connection is self-locking, fixing the bite pad sleeve 4 in place after adjustment. The threaded connecting tube 7 also securely connects to the bite pad sleeve 4, dividing it into two sections, A and B. During use, the endotracheal tube 1 is inserted through the patient's mouth, through the glottis, and into the trachea. The bite pad sleeve 4 is screwed onto the threaded connecting tube 7 to the position of the patient's teeth, so that the patient's teeth bite on segment A. The sleeve wings 5 ​​limit the position of the patient's teeth bite. This not only prevents the endotracheal tube 1 from being damaged by the patient's teeth by the bite pad sleeve 4, but also protects and limits the patient's teeth by the sleeve wings 5 ​​to prevent the endotracheal tube 1 from falling out. Secondly, a cuff 2 is fixedly connected to one end of the endotracheal tube 1, so that the cuff 2 can be inflated and fixed to the front end of the endotracheal tube 1, so as to facilitate the use of limiting and fixing the endotracheal tube 1. A high-pressure tube 3 is fixedly connected to the endotracheal tube 1 and connected to the cuff 2, so that the cuff 2 can be inflated through the high-pressure tube 3.
