[0002] Drainage catheters are generally used after surgical operations, mainly to guide pus, waste blood, and waste fluid accumulated in human tissues or body cavities to the outside of the body to prevent postoperative infection and promote wound healing. There are many types of drainage catheters currently used in clinical surgery, but they generally have the following problems: 1. The drainage port is easily blocked by human tissue fragments, physiological residues, and blood clots; 2. The angle of placement of the drainage catheter during burial is deviated, resulting in unsatisfactory drainage effect. These defects not only bring pain to patients, but also bring many inconveniences to clinical use.

[0003] In the prior art, the comparative document CN215460644U provides a spiral drainage catheter, in which, when used by medical staff, medical staff are required to set a pre-buried wound, and then insert the drainage tube into the position of the pre-buried wound and push it into a position with more fluid accumulation. This not only increases the workload of medical staff, but also increases the discomfort of patients. Utility Model Content

[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0027] This specific embodiment provides a drainage device, which solves the technical problem in the prior art that medical staff are required to set up drainage tubes in advance and embed them in wounds, which increases the workload of medical staff and the discomfort of patients.

[0028] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to the solutions required as the utility model described in the claims.

[0029] Reference Figure 1-Figure 7 The utility model provides a drainage device, including a puncture needle 1, a drainage tube 2, and a negative pressure drainage ball 3. One end of the drainage tube 2 is connected to the puncture needle 1, and the drainage tube 2 and the puncture needle 1 are set as an integrated structure. The puncture needle 1 brings the drainage tube 2 to the drainage position, and the puncture needle 1 passes out of the patient's body and is separated from the drainage tube 2. The end of the drainage tube 2 extending out of the patient's body is connected to the negative pressure drainage ball 3 to drain the effusion. Specifically, when people use it, because the puncture needle 1 and the drainage tube 2 are set as an integrated structure, the connection position between the puncture needle 1 and the drainage tube 2 can form a smooth circumferential surface, avoiding the formation of a boss at the connection position between the two, reducing the impact of puncture on the patient. In order to prevent the damage caused, when the puncture needle 1 is inserted, the puncture needle 1 first enters the patient's body and brings the drainage tube 2 to the position where drainage is required. At the same time, the puncture needle 1 is inserted out of the patient's body, and the puncture needle 1 is cut off. The drainage tube 2 is connected with the negative pressure drainage ball 3. The accumulated fluid is sucked out of the patient's body under the action of the negative pressure drainage ball 3. By arranging the drainage needle on the drainage tube 2, the size of the incision for placing the drainage tube 2 is reduced, and the damage to the patient is reduced. At the same time, it is also convenient for medical staff to place the drainage tube 2, reducing the workload of medical staff. Under the action of the drainage ball, the accumulated fluid or inflammatory secretions in the patient's body can be thoroughly attracted and drained, thereby reducing the risk of infection and adhesion in the patient.

[0030] In this embodiment, in order to facilitate drainage of the drainage tube 2, the drainage tube 2 includes a circular tube section 21 and a drainage section 22. The inner cavity of the drainage section 22 is connected to the inner cavity of the circular tube section 21. A drainage port 23 is provided on the side wall of the drainage section 22. The drainage port 23 is spirally arranged along the length direction of the drainage section 22, and the drainage port 23 extends to the circular tube section 21. With such an arrangement, along the length direction of the drainage tube 2, no matter where the accumulated fluid is, since the drainage port 23 is spirally arranged along the circumferential direction, the accumulated fluid can be adsorbed into the drainage tube 2, and then enter the inner cavity of the drainage section 22 and the inner cavity of the circular tube section, and the accumulated fluid can be drained out under the action of the negative pressure drainage ball.

[0031] In this embodiment, in order to facilitate the viewing of the length of the drainage tube 2 in the patient's body and prevent the medical staff from taking the drainage tube 2 out, the scale 24 on the drainage tube 2 and the number corresponding to the scale 24 are provided along the length direction of the drainage tube 2. When the medical staff pulls the drainage tube 2 out, it is convenient for the doctor to observe the length of the spiral drainage section 22 of the drainage tube 2 placed in the human body, which serves as a guide for the doctor when cutting.

[0032] In this embodiment, in order to prevent the drainage section 22 from being squeezed flat during use, the inner cavity of the drainage section 22 is designed with a support body 25, which extends into the inner cavity of the circular tube section. The support body 25 supports the side wall of the drainage section 22 to prevent the drainage port 23 from closing under the action of pressure, which would affect the drainage tube 2 from draining the accumulated fluid.

[0033] In this embodiment, a warning point 26 is provided on the side wall of the drainage tube 2. The black warning point 26 facilitates the doctor to observe the position where the drainage tube 2 is placed to prevent the spiral drainage section 22 of the drainage tube 2 from being taken out of the body.

[0034] In this embodiment, a developing line 27 is provided on the drainage tube 2 along the length direction of the drainage tube 2 . The developing line 27 is spirally arranged on the drainage tube 2 . The developing line 27 facilitates the doctor to observe the position of the drainage tube 2 in the body.

[0035] The present embodiment provides a structure of a support body 25, which is arranged in a cross shape to divide the inner cavity of the drainage section 22 into four cavities, and a drainage port 23 is arranged on each cavity, that is, the drainage ports 23 are evenly arranged on the circumference of the drainage section 22, and there are multiple drainage ports 23. When one of the cavities is blocked, the accumulated fluid can also be drained out from other drainage ports 23.

[0036] This embodiment provides a second structure of the support body 25 , which is arranged in a straight line shape to divide the inner cavity of the drainage section 22 into two cavities, and each cavity is provided with a drainage port 23 , that is, the drainage ports 23 are evenly arranged on the circumference of the drainage section 22 .

[0037] This embodiment provides a third structure of the support body 25 , which is arranged in a Y shape to divide the inner cavity of the drainage section 22 into three cavities, each of which is provided with a drainage port 23 , that is, the drainage ports 23 are evenly arranged on the circumference of the drainage section 22 .
