Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically an oxygen delivery tube connection structure. Background Technology

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items that are used directly or indirectly on the human body, including the necessary computer software. Medical devices include medical equipment and medical consumables. Their efficacy is mainly obtained through physical means, not through pharmacological, immunological or metabolic means, or although these means are involved, they only play an auxiliary role.

[0003] Traditional oxygen tubing lacks a structure to secure it when connected to an oxygen device interface, resulting in a loose connection that is prone to slippage. Furthermore, the oxygen tubing can easily be pulled off the device interface when the patient moves. Therefore, those skilled in the art have provided an oxygen tubing connection structure to address the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to provide an oxygen delivery pipe connection structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oxygen delivery pipe connection structure, including an oxygen equipment interface, one end of which is connected to an installation screw tube, an oxygen conduit sleeved on the outer wall of the oxygen equipment interface, and an oxygen delivery pipe connected to the end of the oxygen conduit away from the oxygen equipment interface, two trapezoidal protrusions fixedly connected to the outer wall of the oxygen equipment interface, and two trapezoidal grooves symmetrically formed on the inner wall of the oxygen conduit, with the two trapezoidal grooves engaging with the two trapezoidal protrusions respectively.

[0006] As a further embodiment of this utility model: the inner wall of the oxygen conduit is tightly fitted to the outer wall of the oxygen equipment interface.

[0007] As a further improvement of this utility model, the trapezoidal protrusion is located on one side of the mounting screw tube.

[0008] As a further improvement of this utility model, the air inlet of the oxygen conduit is sealed and in contact with the air outlet of the oxygen equipment interface.

[0009] As a further improvement of this utility model, the oxygen conduit and gas delivery pipe are made of rubber.

[0010] As a further improvement of this utility model, the diameter of the mounting screw tube is larger than the diameter of the oxygen equipment interface.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The oxygen conduit can be fitted onto the oxygen equipment interface for connection and installation. The installation screw installed on the oxygen equipment interface can be connected to the oxygen equipment. When the oxygen conduit is fitted onto the oxygen equipment interface, the two trapezoidal protrusions can be inserted into the trapezoidal groove for fixation to prevent loosening and falling off.

[0013] This invention is simple to use. Trapezoidal protrusions can be inserted into both trapezoidal slots to fix the oxygen equipment interface and prevent it from loosening. It is easy to disassemble, and the fixation is firm and not easy to loosen. Attached Figure Description
