It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here.

[0023] In order to solve the problems existing in the prior art, the present application provides a three-way connector with a lock. Specifically, Figure 1 and Figure 2As shown, the three-way joint includes a three-way component 1, a locking rubber ring 2, a limit knob 3 and a soft rubber tube 4; wherein the three-way component 1 includes a positioning head 11, an attraction head 12 and a connecting head 13; the locking rubber ring 2 is arranged inside the positioning head 11; the limit knob 3 is connected to the positioning head 11; and the soft rubber tube 4 is connected to the connecting head 13.

[0024] By connecting electronic bronchoscopes without working channels of different specifications, suction tubes and suction devices to the three-way connector, the electronic bronchoscope is used in conjunction with the suction tube for auxiliary suction. This avoids the discomfort caused by blind suction to the patient, improves the efficiency of visual suction, and solves the problem of cumbersome subsequent disinfection process.

[0025] Further, such as Figure 2 and Figure 3 As shown, the positioning head 11 also includes an external thread 111, a first limiting step 112, a fourth limiting step 113 and a fifth limiting step 114, the first limiting step 112 is connected to the end of the external thread 111, the first limiting step 112 is located below the external thread 111, the fourth limiting step 113 and the fifth limiting step 114 are arranged inside the positioning head 11, wherein the fourth limiting step 113 is arranged below the fifth limiting step 114.

[0026] For further information, please refer to Figure 3 The locking rubber ring 2 is arranged between the fourth limiting step 113 and the fifth limiting step 114. When the limiting knob 3 is rotated, with the cooperation of the internal thread 32 and the external thread 111, the distance between the fourth limiting step 113 and the fifth limiting step 114 changes, causing the locking rubber ring 2 to deform, and the size of the inner hole of the rubber ring also changes accordingly, realizing the free switching of the size of the channel opening in the positioning head 11, thereby locking the electronic bronchoscope insertion tube 5 inserted into the positioning head 11, and ensuring that the suction head 12 and the connecting head 13 are normally connected without being affected.

[0027] In one embodiment, after the electronic bronchoscope insertion tube 5 is inserted into the positioning head 11, when a force in a first direction is applied to the limit knob 3, the limit knob 3, with the cooperation of the internal thread 32 and the external thread 111, presses the locking rubber ring 2 to prevent the insertion tube from loosening, thereby achieving the positioning effect of the electronic bronchoscope. After the suction is completed, when a force in a second direction is applied to the limit knob 3, the locking rubber ring 2 is relaxed, so that the insertion tube can be easily removed.

[0028] Furthermore, the attraction head 12 may be a pagoda joint 121, which can play an anti-slip role. It is understandable that the attraction head 12 may also be other joints of any shape with an anti-slip design.

[0029] For further information, please refer to Figure 3The connector 13 also includes a second limiting step 131, which is disposed above the connector 13. The soft rubber tube 4 is fixed to the connector 13 by the second limiting step 131. The soft rubber tube 4 is used to insert the disposable suction tube 6 for suction connection.

The internal thread 32 is arranged inside the limit knob 3 and is used to connect with the external thread 111. After the limit knob 3 and the positioning head 11 are assembled, the third limit step 33 is buckled on the first limit step 112, and the anti-slip protrusion 31 prevents the knob from slipping when rotating.

[0031] In one example, the anti-slip protrusions 31 are circumferentially arranged on the outer wall surface of the limit knob 3 .

[0032] In another example, the anti-slip protrusion 31 is constructed as two ears symmetrically distributed on the outer wall of the limit knob 3, and a rotation mark is provided on at least one of the ears. It can be understood that the anti-slip protrusion 31 can also be any other protrusion of any shape with anti-slip effect.

[0033] In one embodiment, the connection of each device is made by using a three-way connector. Figure 4 .

[0034] Specifically, first, completely insert the pagoda head of the disposable suction tube 6 into the soft rubber tube 4 and ensure that it cannot slip out; then insert the electronic bronchoscope insertion tube 5 of suitable specifications without working channels into the disposable suction tube 6 through the limit knob 3 and the positioning head 11 of the three-way assembly 1, and make the front end of the insertion tube flush with the head of the suction tube, apply a first direction force to rotate the limit knob 3 so that the insertion tube is positioned and cannot slide freely inside the three-way joint; finally, connect the suction device through the suction head 12 to realize visual suction. It can be understood that the joint of the disposable suction tube 6 can also be other joints of any shape with anti-slip effect.

[0035] The locking three-way joint of the present scheme includes a three-way component 1, a locking rubber ring 2, a limit knob 3 and a soft rubber tube 4; the three-way component 1 includes a positioning head 11, an attraction head 12 and a connecting head 13; the positioning head 11 is provided with a fourth limit step 113 and a fifth limit step 114, the fourth limit step 113 is arranged below the fifth limit step 114, the locking rubber ring 2 is arranged between the fourth limit step 113 and the fifth limit step 114, and the aperture size of the locking rubber ring 2 changes with the change of the spacing distance between the fourth limit step 113 and the fifth limit step 114; the locking rubber ring 2 is arranged inside the positioning head 11; the limit knob 3 is connected to the positioning head 11; the soft rubber tube 4 is connected to the connecting head 13. The utility model can connect electronic bronchoscopes without working channels of different specifications, sputum suction tubes and sputum suction devices to the three-way joint by adapting the aperture changes of the locking rubber ring. The electronic bronchoscope is used in conjunction with the sputum suction tube for auxiliary sputum suction, thereby realizing efficient and convenient visual sputum suction and making the subsequent cleaning and disinfection process simpler.
