Description

Technical Field

[0001] The invention relates to the field of medical appliances, and in particular to an anesthesia catheter fixing mechanism. Background Art

[0002] In the medical field, anesthesia catheters are important equipment for delivering anesthetic drugs and oxygen. However, the traditional fixation method is to stick the exposed part of the catheter to the patient's skin with tape. However, when the patient moves, due to the uncertainty of the friction force and friction coefficient between the tape and the skin surface, the tape can easily slip, causing the catheter to be inserted deeper into the body, or even causing the catheter to fall out of the human body, which has a poor fixation effect on the catheter and even poses risks to the patient's treatment and safety.

[0003] Therefore, there is an anesthesia catheter fixer with patent number CN220477928U for solving the above problems. However, the device has the following defects when used, such as: when the diameter of the catheter is small or not particularly large, it is easy for it to slip out of the groove, thereby affecting the stability of the catheter. Similarly, when the diameter of the catheter is not particularly compatible with the diameter of the fixing groove, it is easy for the fixing groove and the anti-slip pattern to fail to effectively fix the catheter. Summary of the invention

[0004] The purpose of the present invention is to provide an anesthesia catheter fixing mechanism.

[0005] The technical problem of the present invention is mainly solved by the following technical solutions:

[0008] Preferably, metal reinforcing ribs are evenly arranged in the side walls of the arc-shaped plate.

[0009] Preferably, an external thread is arranged on the outer arc wall of the arc-shaped plate, and an internal thread matching the external thread is arranged on the side wall of the fixing channel.

[0010] Preferably, alignment notches corresponding to both sides of the opening end of the arc-shaped plate are longitudinally arranged on the side wall of the fixed channel.

[0011] Preferably, a groove connected to the installation channel is provided on the outer wall of the substrate, wherein the diameter of the groove is larger than the inner diameter of the installation channel, and a magnetic connection layer is provided in the side wall of the groove, and a metal block located in the groove and movably connected to the magnetic connection layer is provided at one end of the fixed column.

[0012] Preferably, the bonding assembly comprises a fixing layer arranged on the bottom end surface of the substrate, wherein a double-sided bonding layer is arranged at the bottom of the fixing layer.

[0025] The method of use of the present invention: Figure 2 As shown, the substrate 1 is bonded to the patient's skin surface by the bonding component 2, and the catheter is inserted into the opening of the arc plate 5 from the strip opening 4, wherein the arc plate 5 is rotated to rotate in the fixing channel 3, so that the opening of the arc plate 5 faces downward and both ends thereof are aligned with the alignment notches 11, at which time the arc plate 5 is screwed to the fixing channel 3 to prevent it from sliding out, and the fixing column 92 is operated to make it slide out of the installation channel 91 and insert into the corresponding strip groove 6 at the same time, and the metal block 13 at the end thereof slides into the groove 12 and is magnetically connected to the magnetic connection layer, and finally as shown in FIG. Figure 1As shown, the strip opening 4 is sealed by the arc plate 5 with the opening facing downward to prevent the catheter in the fixed channel 3 from sliding out through the strip opening 4, and the arc plate 5 is prevented from rotating in the fixed channel 3 by inserting the fixing column 92 into the strip groove 6, and the arc plate 5 is screwed to the fixed channel 3, so that it can effectively prevent the arc plate 5 from rotating, and indirectly fix the catheter in the fixed channel 3;

[0026] At the same time, gas can be injected into the airbag layer 7 through the air injection pipe 8 to make it expand, wherein the expanded airbag can fill the gap between the catheter and the side wall of the arc plate 5, so that they are in full contact with each other, preventing the catheter from sliding in the above space to improve its stability. At the same time, the flexible airbag layer 7 is not easy to damage the catheter.
