Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to an anti-blocking drainage device. Background Art
[0002] Drainage technology and drainage devices are widely used in various medical activities. There are many types of surgical drainage tubes used clinically, some are used for urinary catheterization, and some are used in cavities such as the chest cavity, brain cavity, and surgical incisions.
[0003] The use of drainage tubes is a necessary step, especially during surgery when the patient needs to drain blood, fluid, body fluids, pus and other fluids out of the body due to invasive surgery, in order to prevent postoperative infection and affect wound healing.
[0004] At present, the drainage tubes commonly used in clinical practice are generally made of materials such as silicone rubber or polyurethane. When in use, a through hole is provided on the side wall of one end of the catheter, and this section is inserted into the drainage site in the body or on the wound surface. The other end can be connected to other external devices such as the drainage tube outside the body, and the drainage is drained to the outside of the body through the pressure of the body, gravity or negative pressure suction. The through hole on the side wall of the drainage tube is easily blocked, and the blockage can be fibrinous exudate, pus, blood clots, etc. Once blocked, methods such as squeezing, suction, and movement often do not work, and the reverse flushing effect is limited, and may even bring exogenous pathogens into the cavity, so it is contraindicated. If the tube is removed too early, it often leads to treatment failure. A second operation to replace the drainage tube not only increases the patient's pain, but also increases their economic burden.
[0005] In clinical practice, the drainage volume of some patients after lumbar surgery still tends to increase on the fourth day after surgery. The reason is that the drainage tube is not draining smoothly. The accumulated fluid reaches a certain volume and the pressure in the surgical area reaches a certain level before it can be discharged from the drainage tube. The longer the drainage tube is placed in the wound or cavity, the more likely it is to be blocked.
[0006] In the above context, how to prevent the drainage tube from being blocked and avoid the accumulation of fluid in the tube that affects the patient's wound healing has become an urgent problem that needs to be solved. Summary of the invention
[0007] The utility model provides an anti-clogging drainage device, which can effectively prevent the drainage tube from being blocked and reduce the pain of secondary catheterization.
[0008] The utility model solves the above technical problems through the following technical solutions:
[0009] A blockage-proof drainage device comprises a drainage tube, a guide tube and a negative pressure liquid storage tank, wherein the guide tube is arranged inside the drainage tube, the inner wall of the drainage tube is closely attached to the outer wall of the drainage tube, one end of the drainage tube is provided with a drainage section, and the other end is connected to the negative pressure liquid storage tank, the side wall of the drainage section is provided with a drainage hole, and one end of the guide tube is provided with a liquid guide hole corresponding to the drainage hole.
[0010] The anti-clogging drainage device is provided with a limiting convex ring outside the drainage tube, the limiting convex ring is arranged at the periphery of the drainage hole, the outer diameter of the limiting convex ring is the same as the inner diameter of the drainage hole, and the limiting convex ring is stuck in the drainage hole.
[0011] The above-mentioned anti-clogging drainage device, the negative pressure liquid storage tank includes a liquid storage box and a negative pressure source, the drainage pipe and the guide pipe are inserted into the liquid storage box, and the negative pressure source is connected to the top of the liquid storage box.

DETAILED DESCRIPTION
[0018] The specific implementation of the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the utility model.
[0019] like Figure 1 to Figure 2 As shown, the utility model includes a drainage tube 1, a drainage tube 2 and a negative pressure liquid storage tank. The drainage tube 2 is arranged in the drainage tube 1, and the inner wall of the drainage tube 1 is closely attached to the outer wall of the drainage tube 2. One end of the drainage tube 1 is provided with a drainage section, and the other end is connected to the negative pressure liquid storage tank. The side wall of the drainage section is provided with a drainage hole 5, and one end of the drainage tube 2 is provided with a liquid guide hole 4 corresponding to the drainage hole 5. The liquid guide hole 4 and the drainage hole 5 are connected to form a body fluid discharge channel together, so that the body fluid enters the drainage tube 2 and then is discharged. After the operation is performed, an anti-blocking drainage tube 1 device is placed for the patient, so that the body fluids such as effusion, blood, pus, etc. in the wound can be discharged smoothly, preventing incision infection and promoting wound healing. When the anti-blocking drainage tube 1 device is placed, the drainage section of the drainage tube 1 is sutured and fixed to the wound, and then the body fluid is introduced into the drainage tube 2 from the drainage hole 5 and the liquid guide hole 4, and finally enters the negative pressure liquid storage tank through the drainage tube 2.
[0020] During use, in order to prevent the drainage hole 5 and the liquid guide hole 4 from being misaligned, resulting in blockage of the discharge channel, a limiting convex ring 6 is further provided on the outside of the drainage tube, and the limiting convex ring 6 is arranged on the periphery of the liquid guide hole 4. The outer diameter of the limiting convex ring 6 is the same as the inner diameter of the drainage hole 5, and the limiting convex ring 6 is stuck in the drainage hole 5. In this way, it can be ensured that the drainage hole 5 and the liquid guide hole 4 are always connected at the port, ensuring the smooth flow of the discharge channel.
[0021] In order to ensure the negative pressure state of the discharge channel, the negative pressure liquid storage tank includes a liquid storage tank and a negative pressure source 7, the drainage tube 1 and the guide tube 2 are inserted into the liquid storage tank, and the negative pressure source 7 is connected to the top of the liquid storage tank.
[0022] In order to prevent body fluid from entering the negative pressure source 7, the liquid storage box includes a box body 8, a top cover 9 and a partition 10. The box body 8 is provided with a partition 10, and the partition 10 divides the box body 8 into two chambers, namely a liquid storage chamber 11 and a negative pressure chamber 12. A vent is provided on the top of the partition 10. The top cover 9 is covered on the box body 8. The drainage tube 1 and the guide tube 2 are inserted into the bottom of the liquid storage chamber 11 to ensure that the body fluid passes through the guide tube 2 directly to the bottom of the vent; the negative pressure chamber 12 is connected to the negative pressure source 7. When the discharged body fluid passes through the guide tube 2 and enters the liquid storage chamber 11, since the bottom end of the guide tube 2 is located below the vent, the body fluid directly reaches the chamber below the vent. The negative pressure source 7 can keep the negative pressure chamber 12 at a negative pressure. Due to the function of the vent hole, the pressure in the liquid storage chamber 11 can be equal to that in the negative pressure chamber 12, thereby ensuring the stability of the negative pressure in the flow guide tube 2 and preventing body fluid from entering the negative pressure source 7. When it is necessary to clean the body fluid in the liquid storage chamber 11, the negative pressure source 7 can be closed, and then the top cover 9 can be removed and the liquid can be dumped and cleaned. The negative pressure source can be a negative pressure tank or a compressed elastic airbag.
[0023] The drainage tube 1 and the drainage tube 2 are made of transparent soft medical silicone, which has high tissue compatibility and is convenient for medical staff to observe the patency of the drainage tube 1 and the color and viscosity of the drainage liquid in the lumen. The drainage tube 1 is equipped with a buckle outside, which can be conveniently hung on the bedside.
[0024] The usage process is as follows: after the operation, first insert the guide tube 2 into the drainage tube 1, and clamp the limiting convex ring 6 in the drainage hole 5, and then suture and fix the drainage section to the wound. If blockage is found, turn off the negative pressure source 7, and then open the top cover 9 on the box body 8 to rotate the guide tube 2 out of the drainage tube 1, and then cover the top cover 9 on the box body 8 to continue the negative pressure drainage.
[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
