Description

Technical Field

[0001] The present application belongs to the technical field of medical devices, and specifically relates to a T-shaped pus drainage tube. Background Art

[0002] Surgical site infection refers to the appearance of redness, swelling, heat, pain, and even pus discharge from the surgical incision. In severe cases, it may be accompanied by systemic infection symptoms, endangering the patient's life. Surgical wound infection is also an event that surgeons often encounter. Severely infected wounds not only bring a lot of pain to patients, but also increase the financial burden on patients. The common treatment for surgical wound infection is: if the local fluctuation is positive or pus oozing out, it needs to be drained in time. Only when the pus is drained cleanly can the infected wound be cured.

[0003] The main equipment for drainage operation is the drainage tube, which is a medical device for clinical surgical drainage. The main function of the drainage tube is to guide the pus, blood, and fluid accumulated between human tissues or in the body cavity to the outside of the body to prevent postoperative infection and promote wound healing. In the prior art, there are many types of surgical drainage tubes used clinically, which are not only used for wounds, but also for the urinary tract, chest cavity, brain cavity, gastrointestinal tract, bile duct and other parts. According to the type, there are chest drainage catheters, ventricular drainage catheters, cerebrospinal fluid external drainage catheters, lumbar external drainage catheters, cranial external drainage catheters, abdominal drainage catheters, chest drainage catheters, ventricular drainage catheters, bile duct drainage catheters, bile drainage catheters, etc.

[0004] The purpose of using drainage tubes in surgery is to guide the pus, blood, and fluid accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection from affecting wound healing. Common drainage tubes are generally made of materials such as silicone rubber or polyurethane. When used, one end of the catheter is inserted into the drainage site in the body or on the wound surface, and the other end can be connected to other external devices such as drainage tubes outside the body. Through internal pressure, gravity or negative pressure suction, the patient's effusion, exudate or gas can be drained to the outside of the body. Drainage tube.

[0033] This application provides a Figure 1 The T-shaped pus drainage tube shown mainly comprises a T-shaped tube 1, an air bag tube 2 and a negative pressure drainage ball 4. The T-shaped tube 1, the air bag tube 2 and the negative pressure drainage ball 4 are sequentially connected in series through a pipeline.

[0034] The T-shaped tube is provided with a transverse tube 12 and a longitudinal tube 11, and the interiors of the transverse tube 12 and the longitudinal tube 11 are connected to form a T-shaped cavity.

[0035] Among them, the transverse tube 12 of this embodiment has multiple seepage holes 122 evenly distributed along the length direction at the top for the inflow of pus; optionally, the interval between two seepage holes 122 is 1 cm, and the aperture range of the seepage holes is 2mm-3mm. The transverse tube 12 of this embodiment has the same diameter as the longitudinal tube 11, and uses common specifications of pipeline models, such as 16#, 18# and 20# medical drainage tubes, and their corresponding diameters are 5.33mm, 6mm, and 6.67mm. Furthermore, the structural dimensions of each section of the pipeline are set according to the characteristics of pus to improve the overall pus drainage efficiency. Therefore, the length of the transverse tube 12 is designed to increase with the increase of the diameter of the T-tube 1; optionally, the ratio of the length of the transverse tube 12 to the diameter of the T-tube 1 is in the range of 7-24. Specifically, if the T-tube 1 is 16#, the length of the transverse tube 12 is set to 5-7cm; if the T-tube 1 is 18#, the length of the transverse tube 12 is set to 8-10cm; if the T-tube 1 is 20#, the length of the transverse tube 12 is set to 15cm. The working position of the transverse tube 12 is located in the sutured wound surface.

[0036] In order to set the flow rate of the transverse pipe 1 to be adjustable, the two ends of the transverse pipe 1 are designed to be open in this embodiment, and a detachable sealing structure is provided; optionally, the detachable sealing structure adopts a sealing cap 121. Further, in order to prevent the sealing cap 121 from falling off, in other embodiments, a metal wire can be inserted into the entire pipeline, one end of the metal wire is fixed to the sealing cap 121, and the other end is passed through a place in the pipeline and fixed to an external device.

[0037] Optionally, the length of the longitudinal tube 11 ranges from 20 cm to 25 cm, and a quick connector is installed at the lower end to connect it to the airbag tube 2. The airbag tube 2 is an airbag catheter, and its appearance is a rugby ball shape with thin ends and a raised middle. The lower part of the airbag tube 2 is connected to the negative pressure drainage ball 4 through the guide tube 3. Among them, the airbag tube 2 can play a role in fixing the whole after expansion.

[0038] Working principle:

[0039] According to the location and size of the wound, a suitable T-tube 1 is selected, the transverse tube 12 is sutured into the wound surface of the patient, and then the whole is fixed by inflating the airbag tube 2. Then, the negative pressure generated by the negative pressure drainage ball 4 is used to suck the pus into the interior of the transverse tube 12 and the longitudinal tube 11 through the seepage hole 122, thereby completing the drainage operation simply.

[0040] This embodiment can be applied to the drainage of pus from wounds such as breast abscess, vaginal stump infection, Bartholin's gland abscess, and skin infection in various parts of the body, and has achieved good therapeutic effects, which can reduce the pain of patients.

[0041] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present application, rather than to limit the scope of protection of the present application. Simple modifications or equivalent substitutions of the technical solution of the present application by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present application.
