Clamping assembly for trachea cannula

Abstract

The clamping assembly for the trachea cannula comprises an elastic seam allowing the trachea cannula to pass through. A vertical gap is reserved between the sliding block and the elastic seaming opening, the lower portion of the sliding block is connected with the elastic seaming opening through the elastic connecting handle, and the included angle of the connecting position of the elastic connecting handle and the elastic seaming opening is an acute angle; the face, opposite to the fixing frame body, of the elastic connecting handle is concaved inwards to form a damping groove used for elastic damping. The positioning assembly is integrally connected with the elastic connecting handle, and the positioning assembly is detachably connected with a trachea cannula. The damping groove plays an elastic damping role in the positioning or loosening operation of the trachea cannula, and effectively prevents impact on the fixing frame main body and fatigue damage of each component caused by excessive force in the operation.

Description

Technical Field

[0001] The utility model patent relates to the technical field of medical devices, in particular to a clamping assembly for endotracheal intubation. Background Art

[0002] Endotracheal tube is used to assist oral endotracheal intubation. The use of endotracheal tube is helpful to absorb airway secretions such as phlegm and reduce nasal irritation. However, the oral cavity is large, and the endotracheal tube is not easy to fix, which is not conducive to oral care.

[0003] In order to facilitate oral care and treatment during the indwelling process of tracheal intubation, various existing tracheal intubation fixing devices mostly realize the lateral movement of the tracheal intubation through the sliding connection between the slider and the fixing frame body; and the depth of the tracheal intubation is adjusted and fixed through the positioning component. The positioning component mostly uses a fixed claw or a belt-type binding structure, such as CN 203790404 U, which clamps the intubation through the intubation fixing claw and can adjust the size of the intubation fixing claw to fix intubations of different sizes; CN 219921777 U uses Velcro to tie the tracheal intubation tightly. The above positioning structure has the following problems when used: when the depth of the tracheal intubation is adjusted, the positioning component needs to be fixed or loosened. At this time, the impact or vibration of the positioning component is easily transmitted to the fixing frame body through the slider, so that the fixing frame body causes pressure on the patient's facial skin and causes discomfort; the tracheal intubation usually requires a certain retention time, and the positioning component is easily deformed under force when under pressure for a long time, affecting the positioning accuracy of the positioning component. Utility Model Content

[0004] The utility model aims to solve the existing technical problems and proposes a clamping assembly for endotracheal intubation.

[0008] A positioning component is integrally connected to the elastic connecting handle, and the positioning component is detachably connected to the endotracheal tube, and is used to adjust the insertion depth of the endotracheal tube; the section where the positioning component and the endotracheal tube are in contact is the positioning section, and the positioning section is arranged near the front end of the elastic bite.

[0009] Preferably, the detachable connection between the positioning assembly and the endotracheal tube is achieved by clamping or bundling the endotracheal tube.

[0010] Preferably, the intersection angle between the elastic connecting handle and the elastic bite is 20-75°.

[0011] Preferably, the number of the shock-absorbing grooves is not less than one, and the plurality of shock-absorbing grooves are equidistantly distributed vertically.

[0012] Preferably, the shock-absorbing groove is arranged parallel to the axis of the elastic bite.

[0015] Preferably, the outer wall of the elastic connecting handle is further provided with reinforcing ribs, and the reinforcing ribs are parallel to the axis of the elastic bite.

[0016] The beneficial effects of the utility model are as follows: the shock-absorbing groove plays an elastic shock-absorbing role in the positioning or releasing operation of the endotracheal tube, effectively preventing excessive force during the operation from causing impact on the fixing frame body and fatigue damage to the components; the positioning component is integrally connected with the elastic connecting handle, which simplifies the assembly steps while fixing the relative position of the slider and the positioning component, ensuring the accuracy of the product positioning function, and reserving sufficient operating space for the lateral movement or depth adjustment of the endotracheal tube; the angle at which the elastic connecting handle is connected to the elastic bite is an acute angle, which improves the structural toughness of the connection between the elastic connecting handle and the elastic bite.
