Description

Technical Field

[0001] This utility model relates to a drainage tube device for preventing blood clots from blocking the tube. Background Technology

[0002] A surgical drainage tube is a medical device used in surgery to guide pus, blood, or fluid accumulated between human tissues or in body cavities to the outside of the body. Its main functions are to prevent postoperative infection and promote wound healing. Surgical drainage tubes use the principle of siphon or negative pressure suction. They are placed in the surgical area or body cavity and then passed through a skin incision to guide pus, exudate, tissue fluid, and other fluids accumulated between human tissues or in body cavities to the outside of the body.

[0003] However, if too much blood clot is drained from the drainage tube in a short period of time during the drainage process, it can easily block the drainage tube, preventing pus, oozing blood, and tissue fluid from smoothly entering the drainage bag, resulting in a slow drainage speed. Usually, when a drainage tube becomes blocked, medical staff need to replace it with a new one. This requires removing the blocked inlet end of the drainage tube from the patient's wound and then replacing it with a new one. This process not only increases the workload of medical staff, but the replacement process can also cause slight tearing of the patient's affected area, which is detrimental to the patient's recovery.

[0027] The present application will be further described below with reference to the drawings and examples.

[0028] As Figures 1-6 shown, a drainage tube device for preventing blood clots from blocking the tube, comprising a drainage tube 10 and a pipe connector 20 arranged at the liquid inlet end of the drainage tube 10, the pipe connector 20 comprising an integrally formed connecting pipe 21 and a dredging pipe 22, the connecting pipe 21 being fixed on the outer wall surface of the drainage tube 10, the dredging pipe 22 being internally connected to the drainage tube 10, and the end cover 221 arranged at the pipe end of the dredging pipe 22 being provided with a insertion hole 220 for inserting a syringe needle into the interior, after the syringe needle (not shown in the figure) is inserted into the insertion hole 220, air or anticoagulant for dredging blood clots can be injected into the interior of the drainage tube; an auxiliary film 30 for plugging the insertion hole 220 can be detachably bonded at the end face of the end cover 221.

[0029] The structures of the components of the present application will be described below respectively.

[0030] As Figure 3 and Figure 4As shown, the end face of the end cover 221 is divided into a rough surface 2212 and a smooth surface 2211, the film 30 is tightly glued to the smooth surface 2211 of the end cover 221, and the insertion hole 220 is located inside the smooth surface 2211, and the film 30 partially extends out of the smooth surface 2211 and is pressed against the rough surface 2212, so that the film 30 can be easily torn off from the rough surface 2212 by medical staff, so as to facilitate the subsequent insertion of the syringe needle into the insertion hole 220; it should be noted that the film 30 can also be a polypropylene film that is easy to be poked open, and in actual use, the needle can be directly poked into the insertion hole 220 to break the film 30.

[0031] The present application is distinguished by the arrangement of the connecting pipe 21 and the dredging pipe 22, and is divided into the following two different embodiments:

[0032] Embodiment one:

[0033] As shown in Figure 1 and Figure 2 , the axis of the dredging pipe 22 is perpendicular to the axis of the connecting pipe 21, and when the syringe needle is inserted into the insertion hole 220, air or anticoagulant can be directly injected into the drainage pipe to dredge the blood clots and avoid the drainage pipe being blocked by the blood clots.

[0034] Embodiment two:

[0035] As shown in Figure 5 and Figure 6 , the dredging pipe 22 is inclined upward along the axial direction of the connecting pipe 21, and the axis of the dredging pipe 22 forms an angle α with the axis of the connecting pipe 21, and the range of α is between 15° and 70°, and preferably, the axis of the dredging pipe 22 is arranged at an angle of 45° with the axis of the connecting pipe 21; when the pipe connector 20 with the above parameters is used, the dredging pipe 22 is inclined upward, and when the syringe injects air or anticoagulant from the insertion hole 220, the air or anticoagulant can enter the drainage pipe downward under the action of gravity, and since the blood and blood clots in the drainage pipe also flow downward, the air or anticoagulant can better assist the blood and blood clots to flow downward, and has the advantage of more efficiently dredging the blood clots.

[0036] The above embodiments are only used to illustrate the present application, and are not limited to the present application, and ordinary skilled in the art can make various modifications or changes without departing from the spirit and scope of the present application, therefore, all equivalent technical solutions should also belong to the scope of the present application, which is limited by the claims.
