Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to a threaded movable endotracheal tube fixation device. Background Technology

[0002] In the medical field, endotracheal intubation is one of the treatment methods used in clinical practice. Endotracheal intubation is the most effective and reliable method for establishing an artificial airway.

[0003] Endotracheal intubation is a technique that involves inserting a specially designed endotracheal tube through the mouth or nose and into the trachea or bronchus via the glottis. This technique ensures that the airway remains open, resolves airway obstruction, ensures unobstructed ventilation and oxygen supply, clears airway secretions, prevents aspiration, and provides the best conditions for assisted or controlled breathing.

[0004] Commonly used for the resuscitation of critically ill patients with endotracheal anesthesia and respiratory dysfunction; suitable for surgical patients undergoing endotracheal general anesthesia; when using muscle relaxants, such as during abdominal surgery; and when respiratory function has not yet recovered postoperatively; for patients with respiratory insufficiency caused by neurological diseases; for emergency resuscitation of respiratory and cardiac arrest; for surgery on the airway, such as nasal and pharyngeal surgery; for patients with predicted difficult airways; for patients at risk of aspiration of gastric contents, blood, etc.; when other ventilation methods are ineffective; for pathological conditions without protective airway reflexes; and for patients requiring prevention of hypercapnia.

[0005] Therefore, in order to solve a series of problems such as overly complicated operation and inadequate fixation during endotracheal intubation, it is necessary to provide an endotracheal intubation fixation device to assist medical personnel in using endotracheal intubation fixation. Summary of the Invention

[0006] This utility model provides a threaded movable endotracheal tube retainer for securing and moving the endotracheal tube left and right.

[0007] The technical solution of this utility model is as follows:

[0008] A threaded movable endotracheal tube retainer, comprising:

[0009] A fixed bracket, wherein a guide rail is mounted on the fixed bracket along the left and right directions;

[0010] A movable support is provided with a sliding groove, and a guide rail is embedded in the sliding groove. The movable support is also provided with a threaded hole and a tracheal tube fixing groove.

[0011] A knob push rod, one end of which passes through the threaded hole and contacts the inner wall of the fixed bracket, and the knob push rod is screwed and fixed to the threaded hole.

[0012] Preferably, the endotracheal tube fixing groove is an annular groove.

[0013] Preferably, a silicone retaining sleeve is installed in the endotracheal tube retaining groove.

[0014] Preferably, the threaded movable endotracheal tube retainer further includes:

[0015] A sponge pad is fixed to the fixed bracket and positioned facing the patient's face.

[0016] Preferably, the threaded movable endotracheal tube retainer further includes:

[0017] A silicone patch, which is fixed to both ends of the fixing bracket and positioned facing the patient's face;

[0018] The sponge pad is placed between the two silicone patches and is positioned facing the patient's philtrum.

[0019] Preferably, the threaded movable endotracheal tube retainer further includes:

[0020] A headband, which is fixed to both ends of the fixed bracket.

[0021] The beneficial effects of this utility model are as follows:

[0022] During endotracheal tube installation, the endotracheal tube is inserted with an interference fit and passes through the endotracheal tube fixing slot. When the endotracheal tube needs to be moved, the knob push rod is turned counterclockwise one full turn to loosen it. The end of the knob push rod extending from the moving bracket is no longer in contact with the inner wall of the fixed bracket. Relying on the cooperation of the slider and guide rail, the moving bracket can be moved left and right relative to the fixed bracket. After moving it into place, the knob push rod is turned clockwise one full turn to tighten it, so that the end of the knob push rod extending from the moving bracket is in contact with the inner wall of the fixed bracket again. The knob push rod generates a force that moves forward continuously, thereby preventing the moving bracket from moving left and right, thus fixing the moving bracket and endotracheal tube.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Reference Figures 1 to 5 This application provides a threaded movable endotracheal tube retainer, comprising:

[0033] Fixed bracket 1, wherein a guide rail 11 is mounted on the fixed bracket 1 along the left and right directions;

[0034] The movable support 2 is provided with a sliding groove 21, the guide rail 11 is embedded in the sliding groove 21, and the movable support 2 is also provided with a threaded hole 24 and an endotracheal tube fixing groove 22.

[0035] A knob push rod 3, one end of which passes through the threaded hole 24 and contacts the inner wall 12 of the fixed bracket 1, and the knob push rod 3 is screwed and fixed to the threaded hole 24.

[0036] When installing the endotracheal tube, insert it with an interference fit and pass it through the endotracheal tube fixing slot 22. When the endotracheal tube needs to be moved, loosen it by rotating the knob push rod 3 one turn in the opposite direction.
