Description

Technical Field

[0001] The utility model relates to the technical field of connecting pipes, and more specifically, the utility model relates to a fixed connecting pipe for connecting a tracheotomy cannula and a ventilator connecting pipe. Background Technique

[0002] A tracheotomy cannula, also known as a tracheostomy cannula or tracheostomy catheter, is a ventilation catheter placed in the trachea through a tracheotomy, used to relieve laryngeal dyspnea, retention of respiratory tract secretions, and perform mechanical ventilation. The ventilator connecting pipe is a gas passage between the ventilator and connecting devices such as an artificial airway or a mask, used to ensure that the ventilator delivers air into the lungs and the gas is discharged from the lungs out of the body. When connecting, one end of the ventilator pipeline needs to be connected to the other end of the tracheotomy cannula, and then the accessories of the ventilator are connected to the ventilator pipeline.

[0003] Among them, through retrieval, it is found that the patent with the patent application number CN201821294844.1 discloses a ventilator pipeline joint for a tracheotomy cannula. The outside of the port of the ventilator pipeline joint includes a first turntable; the first turntable and the second turntable are rotatably combined through a pivot; the second turntable is fixedly connected to the cannula; a torsion spring is arranged between the cannula and the ventilator pipeline joint; a threaded hole is opened on the side wall of the cannula, and a screw is installed in the threaded hole; a clamping arm is inserted into the cannula, and the clamping arm includes a clamping head, a cross bar, and a tail handle; the clamping head is perpendicular to the cross bar; the clamping head is used to abut against the laterally extending rear side formed at the rear end of the port of the tracheotomy cannula; the tail handle extends downward from the end of the cross bar; the end of the screw abuts against the side of the cross bar to fix the cross bar in the cannula;

[0004] When this structure is in use, by arranging a clamping arm on the joint of the ventilator pipeline and clamping it at the rear end of the port of the tracheotomy cannula, it can effectively prevent the joint of the ventilator pipeline from disengaging from the port of the tracheotomy cannula. However, this structure is not easy to form a wrapping clamping function for the pipeline during use, nor is it easy to quickly disassemble and assemble the pipeline. Content of the Utility Model

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a fixed connecting pipe for connecting a tracheotomy cannula and a ventilator connecting pipe, aiming to solve the problems raised in the above background technique.

[0006] The utility model is implemented as follows. The utility model provides the following technical solution: a fixed connecting pipe for connecting a tracheotomy cannula and a ventilator connecting pipe, including a joint for support;

[0007] A first connecting pipe is arranged in the middle of the joint, and support frames for support are arranged on both sides of the surface of the joint, and connecting rods are arranged in each of the support frames;

[0008] A pressure head for limiting is arranged on the top of the connecting rod, a transition block is arranged on the bottom of the connecting rod, an offset opening is opened in the middle of the support frame and on the surface of the joint, the pressure head passes through the offset opening and extends to the outside of the first connecting pipe, a cross bar is arranged on the connecting rod and in the middle of the support frame, and the cross bar is rotatably connected to the support frame.

[0009] A second connecting pipe is provided at the bottom of the joint, the second connecting pipe is connected to the joint and the first connecting pipe, a threaded sleeve is connected to the outer side of the second connecting pipe, the vertical cross-section of the threaded sleeve is set to a cone, the outer side of the threaded sleeve extends to the bottom of the transition block, the vertical cross-section of the side of the pressure head facing the first connecting pipe is set to an arc, and the outer side of the pressure head is provided with an anti-slip sleeve;

[0010] It can be seen that in the above technical solution, the screw top sleeve is displaced on the second connecting tube when it rotates, so that the transition block can contact the screw top sleeve, and the traction force of the transition block and the connecting rod when the screw top sleeve is displaced drives the pressure head to rotate along the axis point of the connection between the cross bar and the support frame, thereby enabling the pressure head to pass through the dislocated opening and approach the outside of the first connecting tube, thereby realizing the function of wrapping and clamping the pipeline.

[0011] Technical effects and advantages of the utility model:

[0012] Through the corresponding coordinated use of various structures, the overall design is simple and the structure is reasonable. The tracheotomy tube and the ventilator connecting tube are respectively installed on the outside of the second connecting tube and the first connecting tube. By rotating the top thread sleeve, the top thread sleeve is displaced on the second connecting tube when rotating, so that the transition block can contact with the top thread sleeve, which is easy for various structures to be linked, and can also be self-locking through the thread.

[0013] In addition, the traction force generated by the transition block and the connecting rod when the screw top sleeve is displaced drives the pressure head to rotate along the axis point of the connection between the cross bar and the support frame, so that the pressure head can pass through the offset opening and approach the outside of the first connecting pipe, thereby realizing the function of wrapping and clamping the pipeline and ensuring the stability of the pipeline installation.
