Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically a drainage tube assembly. Background Technology

[0002] Drainage tubes are mainly used to guide pus, blood, and body fluids accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and promote wound healing. In some cases, critically ill patients need to use drainage tubes during treatment or nursing care.

[0003] Existing drainage tubes mainly consist of a tube body and a balloon. The tube body is often made of materials such as silicone, rubber, or plastic, and is flexible with its diameter and length determined by drainage needs. A connector at one end of the tube body is used to connect a collection device and has a leak-proof function. Some drainage tubes have a retainer on the outside. The balloon is connected to the end of the drainage tube to achieve negative pressure drainage. In use, the drainage tube body and balloon are first assembled together. The balloon is then compressed to deflate, and the end of the drainage tube body is inserted into the area where the patient needs to undergo surgical drainage. Afterward, the balloon is released, and it tends to return to its original shape due to its elastic deformation properties. Under negative pressure, pus, blood, and body fluids accumulated in the interstitial spaces or body cavities are drawn into the drainage tube body, achieving the drainage purpose.

[0004] However, when using the above solution, the suction force generated by the negative pressure limits the space inside the balloon for storing pus, blood, and body fluids due to the internal volume of the tube, resulting in a low utilization rate of the balloon. In addition, since the balloon and drainage tube are not integrally formed, the structure is relatively complex, the risk of leakage is relatively high, the storage convenience is poor, and the difficulty of medical waste disposal is increased. Therefore, this application provides a drainage tube assembly. Utility Model Content

[0005] To address the shortcomings of the existing technology, the present invention aims to provide a drainage tube assembly that simplifies the use of the balloon, reduces the overall size of the device, facilitates storage and placement, and prevents leakage of collected pus, blood, and body fluids at the connection point between the balloon and the drainage tube, thus providing reliable protection for medical procedures.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0007] A drainage tube assembly is provided, including a drainage tube and two flexible magnetic strips. The end of the drainage tube is integrally formed with a flat end, which is sealed. The two flexible magnetic strips are respectively disposed on the upper and lower sides of the flat end, and are connected by magnetic attraction coupling, so that the interior of the flat end is in a closed state. The other end of the drainage tube is provided with an inlet, and a connector is detachably and fixedly installed at the inlet.

[0008] Furthermore, a constant position clamping roller and a sliding clamping roller are respectively attached to the upper and lower sides of the flat end, and a positioning arm is connected between the end of the constant position clamping roller and the end of the sliding clamping roller, and a handle is fixedly installed between the two positioning arms.

[0009] In this application, one possible technical solution for the connection between the constant position clamping roller and the sliding clamping roller and the positioning arm is that the constant position clamping roller and the sliding clamping roller are respectively detachably and fixedly connected to the positioning arm.

[0010] In this application, another optional technical solution for the connection between the constant position clamping roller and the sliding clamping roller and the positioning arm is as follows: the end of the constant position clamping roller is rotatably connected to the positioning arm, the end of the sliding clamping roller is slidably connected to the slide groove on the positioning arm, a pressing slider is vertically slidably installed in the slide groove, a stud is rotatably installed on the top of the pressing slider, and the stud passes through the positioning arm and is connected to the positioning arm by threaded engagement.

[0011] Furthermore, the positioning arm is connected to an arc-shaped clamp via a cross arm, and the inner side of the arc-shaped clamp abuts against the outer side of the drainage tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The drainage tube assembly of this utility model, when pressed at the flat end, causes the upper and lower sides of the flat end to come closer together and fit together under the magnetic attraction of the two flexible magnetic strips, so that the interior of the flat end is closed together, expelling the air inside and sealing it. During this process, the air originally stored inside the flat end is discharged from the inlet. The inlet is inserted and connected to the patient's affected area. The side of the drainage tube closest to the inlet is defined as the front. From front to back, the two sides of the drainage tube are pressed, causing the two flexible magnetic strips to move away from each other and break their mutual attraction. This creates negative pressure inside the drainage tube, achieving the purpose of absorbing and draining pus, blood, and body fluids. Because it simplifies the use of the balloon, reduces the overall size of the device, and is easy to store and place.

[0014] 2. The drainage tube assembly of this utility model allows the flat end to be inserted between the constant position clamping roller and the sliding clamping roller. By holding the handle, the two positioning arms can be moved synchronously. When sliding forward, the constant position clamping roller and the sliding clamping roller automatically press the upper and lower sides of the flat end, causing the interior of the flat end to close. When sliding backward, the arc-shaped clamps on both sides automatically squeeze the left and right sides of the flat end, causing the flat end to reopen. The drainage tube assembly has good stability in use and makes it easy to control the speed of aspiration of pus, blood, and body fluids, providing reliable protection for medical operations.

[0025] Example 1:

[0026] like Figure 1 As shown, this embodiment provides a drainage tube assembly, including a drainage tube 11 and two flexible magnetic strips 12. The drainage tube 11 is made of light-transmitting PVC or silicone material. A flat end 112 is integrally formed at the end of the drainage tube 11, and the end of the flat end 112 is sealed. The two flexible magnetic strips 12 are respectively disposed on the upper and lower sides of the flat end 112, and the two flexible magnetic strips 12 are connected by magnetic attraction coupling. An inlet is provided at the other end of the drainage tube 11. A sealing cap is detachably installed at the inlet, and a connector 111 is detachably fixed at the inlet. Different connectors 111 can be replaced to be used for patients with different wounds.

[0027] When using the drainage tube assembly of this application to aspirate and drain pus, blood and body fluids from a patient's affected area;

[0028] First, remove the sealing cap on the inlet of the drainage tube 11 and press the flat end 112. Under the magnetic attraction of the two flexible magnetic strips 12, the upper and lower sides of the flat end 112 approach and fit together, so that the inside of the flat end 112 is closed, the air inside is discharged and sealed. During this process, the air originally stored inside the flat end 112 is discharged from the inlet.

[0029] Next, the inlet is connected to the patient's affected area. The side of the drainage tube 11 closest to the inlet is defined as the front. From front to back, press both sides of the drainage tube 11 to make the two flexible magnetic strips 12 move away from each other and break their adsorption state. This creates negative pressure inside the drainage tube 11, achieving the purpose of absorbing and draining pus, blood, and body fluids. Because it simplifies the use of the balloon, it reduces the overall size of the device and makes it easy to store and place.

[0030] Compared to traditional drainage tubes with balloons at the ends, the drainage tube of this application is integrally molded, which effectively avoids leakage of collected pus, blood, and body fluids at the connection point between the balloon and the drainage tube, and facilitates the disposal of medical waste.

[0031] Example 2:

[0032] The features that are the same as those in Embodiment 1 will not be repeated here. The difference between this embodiment and Embodiment 1 is that: Figure 1 and Figure 2 As shown, in this embodiment, a constant position clamping roller 221 and a sliding clamping roller 222 are respectively attached to the upper and lower sides of the flat end 112. A positioning arm 22 is connected between the end of the constant position clamping roller 221 and the end of the sliding clamping roller 222. A handle 21 is fixedly installed between the two positioning arms 22. An arc-shaped clamping plate 24 is connected to the positioning arm 22 through a cross arm 23. The inner side of the arc-shaped clamping plate 24 abuts against the outer side of the drainage pipe 11.

[0033] Insert the flat end 112 between the constant position clamping roller 221 and the sliding clamping roller 222, hold the handle 21, and control the two positioning arms 22 to move synchronously; when sliding forward, the constant position clamping roller 221 and the sliding clamping roller 222 automatically press the upper and lower sides of the flat end 112, so that the interior of the flat end 112 closes; when sliding backward, the arc-shaped clamping plates 24 on both sides automatically squeeze the left and right sides of the flat end 112, so that the flat end 112 reopens.

[0034] Using the above method improves the stability of the drainage tube assembly, makes it easier to control the speed of aspiration of pus, blood and body fluids, and provides reliable protection for medical operations.

[0035] In this embodiment, the constant position clamping roller 221 and the sliding clamping roller 222 are detachably and fixedly connected to the positioning arm 22.

[0036] Example 3:

[0037] The features that are the same as those in Embodiment 2 will not be repeated here. The difference between this embodiment and Embodiment 2 is that: Figure 2 As shown, in this embodiment, the end of the constant position clamping roller 221 is rotatably connected to the positioning arm 22, the end of the sliding clamping roller 222 is slidably connected to the sliding groove on the positioning arm 22, a pressing slider 25 is vertically slidably installed in the sliding groove, and a stud 26 is rotatably installed on the top of the pressing slider 25. The stud 26 passes through the positioning arm 22 and is connected to the positioning arm 22 by threaded engagement.

[0038] Rotating the stud 26 causes the pressing slider 25 to slide vertically within the groove, adjusting the distance between the constant position clamping roller 221 and the sliding clamping roller 222. This allows for the use of drainage pipes 11 of different thicknesses or materials, offering good versatility and high operational flexibility.
