[0023] Based on this, in order to improve the problem in the related art that the position of the end of the drainage tube is difficult to adjust during intubation, the embodiment of the present application provides the following solution.

[0024] The following combination Figure 1-Figure 6 The utility model is described in further detail.

[0025] The present embodiment discloses an adjustable angle abdominal drainage tube: an adjustable angle abdominal drainage tube comprises a hose 1, a connector 2, a guide tube 3 and a control mechanism 4, one end of the hose 1 is inserted into the connector 2 and fixedly connected to the connector 2, the guide tube 3 is inserted into the hose 1 and the connector 2 in sequence, two installation grooves 31 are symmetrically opened inside the guide tube 3, an elastic strip 32 is arranged inside the installation groove 31, an end of the elastic strip 32 away from the connector 2 is fixedly connected to the guide tube 3, and the control mechanism 4 is arranged at one end of the guide tube 3 close to the connector 2, and is used to control the bending of the two elastic strips 32 to control the guide tube 3 to bend in a fixed direction;

[0026] The control mechanism 4 includes a mounting plate 41, a shell 42 and two threaded pins 43. One side of the mounting plate 41 abuts against the side of the connector 2 away from the hose 1. The shell 42 is fixedly arranged on the side of the mounting plate 41 away from the connector 2. Two threaded holes 421 are symmetrically provided on the shell 42. The threaded pins 43 are threadedly connected inside the threaded holes 421. One end of the elastic strip 32 close to the shell 42 passes through the mounting plate 41 and is rotatably connected to one end of the threaded pin 43 close to the mounting plate 41.

[0027] A spherical connecting groove 431 is formed at one end of the threaded pin 43 close to the mounting plate 41 , a connecting ball head 432 is rotatably arranged inside the spherical connecting groove 431 , and one end of the elastic strip 32 close to the threaded pin 43 is fixedly connected to the connecting ball head 432 .

[0028] As can be seen from the above, an angle-adjustable abdominal drainage tube provided by an embodiment of the present application, when performing an intubation operation, the hose 1 is inserted into the patient's abdominal cavity through a surgical incision, and after the end of the hose 1 is close to the drainage position, when the hose 1 needs to be bent to one side, the threaded pin 43 located on this side is twisted to make it move inside the threaded hole 421 in a direction away from the mounting plate 41, and the connecting ball head 432 rotates relative to the threaded pin 43 inside the spherical connecting groove 431, and when the threaded pin 43 moves, the elastic strip 32 is pulled toward the outside of the guide tube 3 through the connecting ball head 432, and the elastic strip 32 applies a pulling force biased toward this side to the end of the guide tube 3 away from the mounting plate 41, and then the threaded pin 43 on the other side is twisted to make the threaded pin 43 move toward the mounting plate 41, and the threaded pin 43 pushes the elastic strip 32 to move inside the guide tube 3 through the connecting ball head 432, and the elastic strip 32 moves the guide tube 3 away from the mounting plate One end of 41 applies a thrust biased towards this side, so that under the action of the elastic strips 32 on both sides, the guide tube 3 bends to the side of the threaded pin 43 that is first screwed. The doctor can repeat the above process to increase the bending angle of the guide tube 3. When it is necessary to reduce the bending angle of the guide tube 3 or to bend the guide tube 3 to the other side, the two threaded pins 43 can be screwed in the opposite direction, so that the shape of the hose 1 can be controlled, and the end of the hose 1 is moved to the drainage position, and then the mounting plate 41 is pulled to pull the guide tube 3 out of the inside of the hose 1 and connect the hose 1 to the drainage bag through the connector 2. In this process, the end position of the hose 1 does not need to be moved outside the abdominal cavity to complete the adjustment of the position of the hose 1, so that the inclination angle between the part of the hose 1 that contacts the surgical incision and the surgical incision can be kept at an appropriate size, which is convenient for the subsequent fixation of the hose 1, thereby facilitating the doctor's operation and reducing the possibility of secondary injury to the patient.

[0029] In some embodiments, please refer to Figure 1 and Figure 2 A fixed cushion 5 is sleeved on the hose 1, and a locking mechanism 6 is provided on the fixed cushion 5. The locking mechanism 6 is used to fix the fixed cushion 5 on the hose 1, and a medical cotton cloth 51 is provided on one side of the fixed cushion 5 away from the connector 2;

[0030] The locking mechanism 6 includes a convergence tube 61 and a locking tube 62, both of which are sleeved on the hose 1. One end of the convergence tube 61 is fixedly connected to a side of the fixed cushion 5 away from the medical cotton cloth 51, and the other end of the convergence tube 61 is provided with a plurality of convergence grooves 611. The inner diameter of the end of the convergence tube 61 with the convergence grooves 611 gradually increases in a direction away from the fixed cushion 5, and the inner diameter of the end of the locking tube 62 close to the convergence tube 61 gradually increases in a direction close to the convergence tube 61.

[0031] In this way, before intubation, the fixing cushion 5 and the locking tube 62 are moved to the end of the hose 1 close to the connector 2, and then the intubation operation is performed. After the intubation operation is completed, the fixing cushion 5 is moved to make the medical cotton cloth 51 fit the surgical incision, and then the fixing cushion 5 is fixed to the patient's skin with medical tape, and then the locking tube 62 is moved to contact the contraction tube 61, the contraction tube 61 is kept stationary and the locking tube 62 is twisted so that the internal thread is connected with the thread on the outer peripheral surface of the contraction tube 61. Since the inner diameter of the end of the locking tube 62 close to the contraction tube 61 gradually increases in the direction close to the contraction tube 61, the locking tube 62 is locked. When the tube 62 rotates and approaches the contraction tube 61, the locking tube 62 causes the end of the contraction tube 61 close to the locking tube 62 to contract inward, and then the locking tube 62 continues to be twisted until the inner circumference of the end of the contraction tube 61 close to the locking tube 62 is pressed against the outer circumference of the hose 1, thereby fixing the hose 1 on the contraction tube 61. This can prevent the hose 1 located outside the patient's abdominal cavity from shaking when being pulled by external force, causing discomfort to the patient; the medical cotton cloth 51 can absorb the body fluid exuded from the surgical incision, keep the surgical incision dry, and reduce the possibility of inflammation at the surgical incision.

[0032] Optionally, see Figure 3 and Figure 5 A plurality of locking teeth 7 are provided on the inner wall of the converging tube 61 .

[0033] With such arrangement, after the converging tube 61 is converging and locking the hose 1 , the locking teeth 7 can increase the friction between the converging tube 61 and the hose 1 , thereby improving the fixing effect of the converging tube 61 on the hose 1 .

[0034] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
