Description

Technical Field

[0001] This utility model relates to the field of medical catheter devices, and in particular to a catheter fixing bite. Background Technology

[0002] In traditional surgical anesthesia, an endotracheal tube is inserted through a bite mark. The tube's function is to deliver oxygen and anesthetic drugs to the patient's lungs and remove exhaled carbon dioxide. The endotracheal tube maintains a clear airway and smooth breathing, ensuring effective delivery of oxygen and anesthetic drugs while expelling exhaled waste gases and maintaining respiratory function. This is crucial for ensuring stable breathing during surgery and the smooth progress of the procedure.

[0003] However, traditional bite-shaped surgical techniques lack dedicated fixation devices for the airway, making it prone to loosening during surgery. If the airway becomes loose during anesthesia, it may lead to the following consequences:

[0004] 1. Insufficient oxygen supply to the patient: A loose airway may cause oxygen leakage, reducing the efficiency of oxygen delivery to the patient's lungs, leading to a decrease in the oxygen content in the patient's body, which may cause insufficient oxygen supply.

[0005] 2. Difficulty breathing: A loose airway may cause airway obstruction or blockage, affecting airway patency and leading to difficulty breathing. This can result in serious consequences such as hypoxia, respiratory distress, or even respiratory failure.

[0006] 3. Impaired carbon dioxide expulsion: A loose airway may affect the expulsion of carbon dioxide, leading to its accumulation in the body and potentially causing carbon dioxide retention and respiratory acidosis.

[0007] 4. Insufficient concentration of anesthetic drugs: Loose airway may lead to poor delivery of anesthetic drugs, resulting in insufficient depth of anesthesia and affecting the outcome of the surgery.

[0008] Therefore, the endotracheal tube plays an important role in anesthesia and surgery, and must be kept in the correct position and fixed to ensure that the patient's airway is open and breathing is normal. Utility Model Content

[0045] Please see Figure 1 and Figure 2The diagram illustrates an embodiment of a catheter fixing joint, characterized by comprising a fixing plate 1, which is curved at a certain arc; and a pin 2, which can be tightly inserted into the fixing plate 1, and which shares a through catheter hole 3 with the pin 2 in a direction substantially perpendicular to the surface of the fixing plate 1; wherein the catheter hole 3 includes a cylindrical hole 31 formed on the fixing plate 1; and a frustum groove 32 formed on the pin 2; wherein the larger end of the frustum groove 32 is close to the fixing plate 1, while the smaller end is away from the fixing plate 1; after the air tube is inserted into the catheter hole 3, the movement of the air tube is restricted by controlling the depth of the pin 2 inserted into the fixing plate 1.

[0046] In this embodiment, see continue to refer to Figure 2 As shown, the fixing plate 1 also includes a biting block 11, which is vertically connected to the center of the fixing plate 1; wherein the guide hole 3 passes through the biting block 11 and the fixing plate 1 connected to the biting block 11.

[0047] In this embodiment, the top of the bite block 11 is provided with a through cut 111 along the axial direction. The cut 111 extends through the fixing plate 1 and is connected to the guide hole 3.

[0048] In this embodiment, as Figure 3 As shown, a pair of positioning wing grooves 12 are provided on the back of the fixing plate 1. The two positioning wing grooves 12 are connected to the cutout 111 and the guide hole 3 on the left and right sides respectively.
