Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a multi-functional connector. Background Technique

[0002] Double-lumen bronchial catheters are widely used in thoracic surgery anesthesia. The initial purpose of their application was to protect the lungs, but currently, they mainly facilitate surgical operations. The absolute indications include situations where ventilation needs to be maintained and the healthy lung needs to be protected from infection, such as wet lung, massive hemoptysis, bronchopleural fistula, single-lung bronchial lavage, etc.

[0003] One-lung ventilation is a lung isolation technique implemented by anesthesiologists for patients undergoing thoracic surgery, which provides a better surgical field exposure for doctors and protects the healthy lung from infection.

[0004] During one-lung ventilation, it is necessary to clamp the second branch of the double-lumen tracheal catheter with pliers (as shown in the attached instructions). Figure 1 However, since there are also pliers on the operating table during the operation, anesthesiologists may also use pliers. If not paying attention, it is easy to make mistakes, resulting in non-standard use of instruments or even insufficient instruments during the operation. Therefore, we propose a multi-functional connector. Content of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages existing in the prior art. During one-lung ventilation, it is necessary to clamp the second branch of the double-lumen tracheal catheter with pliers. However, since there are also pliers on the operating table during the operation, anesthesiologists may also use pliers. If not paying attention, it is easy to make mistakes, resulting in non-standard use of instruments or even insufficient instruments during the operation.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A multi-functional connector includes a main tube of a double-lumen tracheal catheter. The front and back sides of the main tube of the double-lumen tracheal catheter are both provided with a first branch of the double-lumen tracheal catheter. The right sides of the two first branches of the double-lumen tracheal catheter are both provided with a second branch of the double-lumen tracheal catheter. A multi-functional connector structure is provided at the connection of the first branch of the double-lumen tracheal catheter near the front side.

[0008] The described multi-functional joint structure includes a structural main body housing. A first diversion pipe is provided on the left side wall of the structural main body housing. A first connector is provided on the left side of the first diversion pipe. A second diversion pipe is provided on the right side of the structural main body housing. A second connector is provided on the right side of the second diversion pipe. A third diversion pipe is provided below the structural main body housing. A third connector is provided below the third diversion pipe. A rotating block is provided on the top of the structural main body housing. A rotating rod is provided on the top of the rotating block. A diversion ring is provided at the bottom of the rotating rod. A rotating shaft is provided at the bottom of the rotating block and on the top of the diversion ring. Three sealing plates are provided on the rotating shaft.

[0009] As a preferred solution of the present invention, the branch pipe of the first double-lumen tracheal catheter is internally connected to the main pipe of the double-lumen tracheal catheter, and the branch pipe of the second double-lumen tracheal catheter is internally connected to the branch pipe of the first double-lumen tracheal catheter.

[0010] The technical effect of adopting the above further solution is that the medium in the main pipe of the double-lumen tracheal catheter will flow into the branch pipe of the second double-lumen tracheal catheter and the branch pipe of the first double-lumen tracheal catheter.

[0011] As a preferred solution of the present invention, the rotating block and the rotating rod are fixedly connected, and the branch pipe of the first double-lumen tracheal catheter is inserted at the first connector.

[0012] The technical effect of adopting the above further solution is that when the rotating block rotates, it will drive the rotating rod to rotate.

[0013] As a preferred solution of the present invention, the rotating shaft and the sealing plate are fixedly connected.

[0014] The technical effect of adopting the above further solution is that when the rotating shaft rotates, it will drive the sealing plate to rotate.

[0015] As a preferred solution of the present invention, the rotating shaft and the diversion ring are fixedly connected.

[0016] The technical effect of adopting the above further solution is that when the rotating shaft rotates, it will also drive the diversion ring to rotate.

[0017] As a preferred solution of the present invention, the first diversion pipe is connected to the third diversion pipe and the second diversion pipe.

[0018] The technical effect of adopting the above further solution is that the medium can enter from any one of the diversion pipes and exit from another diversion pipe.

[0019] Compared with the prior art, the beneficial effect of the present invention is:

[0020] In the present invention, through the design of the multi-functional joint structure, the sealing plate of this functional joint structure rotates to the state as shown in the attached drawings of the specification.Figure 3 When shown as such, all the diversion tubes are in a non-flowing closed state, eliminating the need for the operation of using pliers to clamp the branch pipe of the second double-lumen tracheal catheter in traditional surgeries. Moreover, the structure of this multi-functional connector is increased to two-channel interfaces, meeting the needs of multiple scenarios and avoiding the situation where, during one-lung ventilation, pliers are required to clamp the branch pipe of the second double-lumen tracheal catheter. However, since pliers are also present on the operating table during the operation and the anesthesiologist may also use them, if not careful, it is easy to make mistakes, leading to non-standard use of surgical instruments or even a shortage of instruments during the operation.
