Abstract
Description
Technical Field
[0001] The present application relates to the technical field of fixation, and in particular to a tracheal tube fixer. Background Art
[0002] Cardiac surgery is a relatively young branch of surgery, primarily treating heart disease through surgery, such as coronary bypass surgery, congenital heart disease surgery, and valve replacement. Common heart conditions treated include congenital heart disease, valvular heart disease, coronary artery disease, thoracic aortic aneurysm, pericardial disease, and cardiac tumors. During cardiac surgery, the patient must be intubated.
[0003] The current method for securing an endotracheal tube typically involves placing a bite block between the patient's upper and lower incisors after confirming successful intubation. The tube and bite block are then tied together with adhesive tape and secured to the patient's cheek. This tube securing method has the following disadvantages: the adhesive tape easily weakens or loses its stickiness, resulting in a loose connection and the tube being easily loosened or misplaced. Furthermore, once the tube is securely positioned, it is difficult to adjust its insertion depth as needed. Therefore, a endotracheal tube fixator has been proposed to address the aforementioned issues. Utility Model Content

[0006] (2) Technical solution
[0007] To achieve the above-mentioned purpose, the present application provides the following technical solution: a tracheal tube holder, comprising a guide tube, wherein two clamping mechanisms are symmetrically arranged inside the guide tube;
[0008] The clamping mechanism includes a clamping plate, which is located inside the guide tube, with a first connecting plate fixedly installed on the top of the clamping plate, a second connecting plate fixedly installed on the top of the first connecting plate via two springs, the second connecting plate fixedly installed on the inner side wall of the guide tube, a pull rod fixedly installed on the top of the first connecting plate, the pull rod is slidably connected to the second connecting plate and the guide tube, the pull rod is located between the two springs, a fixing cloth is longitudinally fixedly installed on the outer side wall of the guide tube, a connecting cover is fixedly installed on the bottom end of the fixing cloth, and a fixing groove is provided on the outer side wall of the connecting cover;
[0009] A limiting mechanism is arranged on the outer side wall of the guide tube.
[0010] Preferably, the limiting mechanism includes a connecting column, which is fixedly mounted on the outer side wall of the guide tube, and two limiting blocks are rotatably mounted on both ends of the connecting column through a plurality of hinges.
[0011] Furthermore, a limiting groove is provided inside each of the limiting blocks.
[0012] Furthermore, an elastic bandage is fixedly mounted on the outer side wall of the fixing cloth.
[0013] On the basis of the above solution, a handle is fixedly mounted on one end of each pull rod away from the splint.
[0014] (3) Beneficial effects
[0015] Compared with the prior art, the present application provides a tracheal tube holder with the following beneficial effects:
[0016] The endotracheal tube fixator guides and isolates the tube through the guide tube, and synchronously drives the first connecting plate and the clamping plate to clamp and fix the tube inside the guide tube through the expansion and contraction of the spring. The patient's face and the guide tube are tightly fitted by the fixing cloth and the connecting cover, and the fixing groove on the connecting cover fits the patient's chin, thereby completing the preliminary fixation of the guide tube by the fixing cloth and the connecting cover, replacing the method of fixing the patient with adhesive tape, improving the effect of the device on fixing the tube, facilitating the adjustment of the tube according to different insertion depths, and improving practicality.
