[0017] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the following further describes in detail a suction and flushing dual-purpose drainage tube proposed by the present invention in conjunction with the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the present invention will be clearer. It should be noted that the drawings are in a very simplified form and use non-precise scales. The orientation or positional relationships indicated by terms such as "center", "lateral", "length", "width", "height", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "side", etc. are based on the orientation or positional relationships shown in the drawings, rather than indicating or implying that a suction and flushing dual-purpose drainage tube or component must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It is only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention. In order to make the objectives, features and advantages of the present invention more obvious and understandable, please refer to the accompanying drawings.
[0018] It should be noted that the structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention. Therefore, they do not have a technical essence. Any modification of the structure, change in the ratio relationship or adjustment of the size, without affecting the effects that the present invention can produce and the objectives that can be achieved, should still fall within the scope covered by the technical content disclosed by the present invention.
[0019] The following describes the specific structure of a suction and flushing dual-purpose drainage tube:
[0020] Please refer to Figure 1 and Figure 2 For the dual-purpose suction and irrigation drainage tube of this embodiment, it includes a first tube 1 and a second tube 2. The first tube 1 is the traditional central control drainage tube, and the second tube 2 is the irrigation tube. The drainage tube further includes a third tube 3. One end of the third tube 3 is connected to the first tube 1. The surface of the third tube 3 is provided with a first groove 301 and a second groove 302. The first groove 301 is circular, with a diameter of 1-3 mm. The second groove 302 is oval, with a major axis of 2-4 mm and a minor axis of 1-3 mm. Preferably, in this embodiment, two of the first grooves 301 and the second grooves 302 are respectively provided and are oppositely arranged. Preferably, the first groove 301 is used for draining small-volume substances, such as seepage fluid, etc., and the second groove 302 is used for draining large-volume substances, such as blood clots, etc.
[0021] Furthermore, first holes 303 are opened in both the first groove 301 and the second groove 302. Preferably, the first holes 303 are opened at the center of the bottom of the first groove 301 and the second groove 302. The third tube 3 also has a third groove 304 opened at the end connected to the first tube 1. The first holes 303 are evenly distributed within the depth range of the third groove 304, and the first holes 303 all penetrate through to the inside of the third groove 304.
[0022] Furthermore, a part of the second tube 2 is fitted and extends into the third groove 304. A second hole 101 is opened on the surface of the first tube 1, and another part of the second tube 2 is fitted in the second hole 101. The part of the second tube 2 protruding from the third groove 304 passes through the first tube 1 and then passes out through the second hole 101.
[0023] Furthermore, the first groove 301 and the second groove 302 penetrate along the length direction of the third tube 3 towards the first tube 1 to achieve drainage.
[0024] The specific working process of the dual-purpose suction and irrigation drainage tube according to the embodiment of the present invention is described as follows:
[0025] The third tube 3 extends into the patient's body. One end of the first tube 1 away from the third tube 3 is connected to a drainage bag or a negative pressure ball. When a negative pressure state is formed, the accumulated fluid in the patient's body flows through the first groove 301 and the second groove 302 to the first tube 1 and is then discharged. During the drainage process, the first holes 303 will inevitably be blocked by the flowing accumulated fluid, etc. At this time, by connecting a water source through the second tube 2, the first holes 303 can be dredged and cleaned.
[0026] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the various technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.
[0027] The above-described embodiments only express several implementation manners of the present utility model, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
