Description

Technical Field

[0001] This utility model relates to the field of drainage tube technology, and more specifically, to an adjustable drainage fixing device. Background Technology

[0002] An abscess is a localized accumulation of pus within a tissue, organ, or body cavity during an acute infection, caused by necrosis and liquefaction of diseased tissue, and surrounded by a complete abscess wall. Abscesses can present with different clinical manifestations depending on their location. Treatment primarily involves drainage. Since they are often focal lesions, the pus is not easily absorbed spontaneously. If not drained promptly, it can worsen the infection, leading to shock and ultimately death.

[0003] There are many existing technologies for pus drainage devices, such as:

[0004] Chinese Patent Publication No. CN217612243U discloses a pus drainage device, including a drainage tube and an irrigation tube. The drainage tube has a drainage cavity and multiple evenly distributed drainage holes on its peripheral wall. The tail end of the drainage tube is connected to a suction connector. The irrigation tube is connected to the drainage tube and has an irrigation cavity located within the drainage cavity. The irrigation tube and the drainage tube are coaxially arranged. A puncture needle is provided within the irrigation cavity, with the needle tip extending out of the irrigation tube and the drainage tube. The end of the drainage tube near the puncture needle is tapered, gradually narrowing towards the needle tip. The tail end of the irrigation tube is connected to an injection connector, which extends out of the drainage tube and is adjacent to the suction connector.

[0005] Therefore, most pus drainage devices currently include an irrigation tube and a drainage tube. The irrigation tube is installed inside the drainage tube, and a locking switch is installed to lock the irrigation tube to prevent accidental movement of the drainage tube during use. However, the drainage tube and the irrigation tube are connected movably, and the locking switch is fixed on the outside of the irrigation tube. This means that the length of the irrigation tube extending through the drainage tube is fixed. As the pus in the abscess gradually drains, the position of the end of the irrigation tube in the abscess needs to be adjusted according to the actual situation of the abscess.

[0006] In view of this, we propose an adjustable drainage fixation device. Utility Model Content

[0007] The purpose of this invention is to provide an adjustable drainage fixation device to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An adjustable drainage fixing device includes an inner tube and a sleeve. One end of the sleeve is provided with a detachable buckle assembly, and the outer side of the inner tube is provided with a slidable limiting assembly. The inner tube passes through the buckle assembly and is slidably connected to the sleeve. The buckle assembly presses the limiting assembly to fix the inner tube.

[0010] As a further embodiment of this utility model: the buckle assembly includes a base plate, a sleeve is provided at the center of the base plate, a slot is provided on one side of the sleeve, and one end of the sleeve is fixed inside the sleeve through the slot.

[0011] As a further embodiment of this utility model: both ends of the base plate are rotatably connected to clamps, and a torsion spring is provided at the connection between the clamps and the base plate.

[0012] As a further embodiment of this utility model: the limiting component includes a first fixing member and a second fixing member, both of which are semi-circular rings, and friction pads are provided on the inner sides of both the first fixing member and the second fixing member.

[0013] As a further embodiment of this utility model: the first fixing member has sliding grooves at both ends, and the second fixing member has fixing posts at both ends, with the fixing posts slidably connected in the sliding grooves; a spring is fixed between the fixing posts and the bottom of the sliding grooves.

[0014] As a further embodiment of this utility model: both the first fixing member and the second fixing member have limit grooves on their outer periphery, and the limit grooves are used to limit the position of the clamping and limiting component.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. After fixing the snap-fit ​​assembly to one end of the sleeve, pass the inner tube through the snap-fit ​​assembly and adjust the extension length of the inner tube inside the sleeve. Then, the inner tube can be fixed by squeezing it with the snap-fit ​​assembly.

[0017] 2. By setting a sliding limiting component at one end of the inner tube, the position of the limiting component in the inner tube can be adjusted, and the limiting component can be squeezed by the snap-fit ​​component, thereby fixing the inner tube. This avoids the snap-fit ​​component directly squeezing the inner tube, which may cause large deformation of the inner tube and make it difficult to drain pus. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] Most pus drainage devices currently include an irrigation tube and a drainage tube. The irrigation tube is installed inside the drainage tube lumen, and a locking switch is installed to lock the irrigation tube to prevent accidental movement of the drainage tube during use. However, the drainage tube and the irrigation tube are connected movably, and the locking switch is fixed on the outside of the irrigation tube. This means that the length of the irrigation tube extending through the drainage tube is fixed. As the pus drains, the entire abscess will gradually shrink. Therefore, it is necessary to adjust the length of the irrigation tube inside the abscess according to the actual situation of the abscess.

[0027] Therefore, please refer to Figure 1 As shown, the purpose of this embodiment is to provide an adjustable drainage and fixation device, including an inner tube and a sleeve. One end of the sleeve is provided with a detachable buckle assembly 100. In use, the inner tube passes through the buckle assembly 100 and is slidably connected to the inside of the sleeve. The other end of the sleeve is inserted into the abscess to drain the pus from the abscess. At the same time, considering that the buckle assembly 100 directly fixes the inner tube, it may cause large deformation when the inner tube is squeezed and fixed, resulting in narrowing of the tube and making it difficult for pus to flow out, a slidable limiting assembly 200 is provided on the outside of the inner tube. The buckle assembly 100 squeezes the limiting assembly 200 to fix the inner tube, thereby limiting the relative position of the inner tube and the sleeve.

[0028] The improvement of this embodiment is as follows: after fixing the snap fastener 100 to one end of the sleeve, the inner tube is passed through the snap fastener 100 and the extension length of the inner tube inside the sleeve is adjusted. Then, the inner tube can be fixed by squeezing the snap fastener 100. By setting a sliding limiting component 200 at one end of the inner tube, the position of the limiting component 200 in the inner tube is adjusted, and the snap fastener 100 squeezes the limiting component 200, thereby fixing the inner tube. This avoids the snap fastener 100 directly squeezing the inner tube, which may cause large deformation of the inner tube and make it difficult to drain pus.

[0029] Please see Figure 2 As shown, considering the sealing between the sleeve and the inner tube to reduce the risk of infection caused by external bacteria entering the abscess through the inner tube, the snap-fit ​​assembly 100 includes a base plate 101. A sleeve 102 is provided at the center of the base plate 101. A slot 103 is provided on one side of the sleeve 102. One end of the sleeve is fixed inside the sleeve 102 through the slot 103. The outer diameter of the inner tube is slightly larger than the inner diameter of the sleeve 102. The inner wall of the sleeve 102 is made of an elastic material, such as rubber or PVC, so that the inner tube can fit against the inner wall of the sleeve 102 and enter the sleeve.

[0030] To facilitate clamping the inner tube, clamps 105 are rotatably connected to both ends of the base plate 101. A torsion spring 104 is provided at the connection between the clamp 105 and the base plate 101. Pressing the clamp 105 causes it to rotate, at which point the latching assembly 100 is in the open state, allowing adjustment of the length of the inner tube inside the sleeve. Releasing the clamp 105 resets it via the torsion spring 104, at which point the latching assembly 100 is in the closed state, and the clamp 105 clamps the inner tube.

[0031] Please see Figure 3 As shown, in order to further enhance the fixing effect of the inner tube and avoid the narrowing of the pipeline caused by the clamp 105 clamping the inner tube, a limiting component 200 is designed. The limiting component 200 includes a first fixing member 201 and a second fixing member 202. Both the first fixing member 201 and the second fixing member 202 are semi-circular rings. Friction pads are provided on the inner side of both the first fixing member 201 and the second fixing member 202. When the first fixing member 201 and the second fixing member 202 are combined into a ring, the inner tube passes through the ring and the friction coefficient is increased by the friction pads, thereby increasing the friction force.

[0032] To facilitate adjustment of the position of the limiting component 200 in the inner tube, the first fixing member 201 has sliding grooves at both ends, and the second fixing member 202 has fixing posts 204 fixed at both ends, with the fixing posts 204 slidably connected in the sliding grooves; a spring 203 is fixed between the fixing posts 204 and the bottom of the sliding groove, and the first fixing member 201 and the second fixing member 202 are in a separated state under normal conditions due to the elastic force of the spring 203;

[0033] Considering that the clamp 105 may detach from the limiting component 200 due to material factors when clamping the first fixing member 201 and the second fixing member 202, limiting grooves 205 are provided on the outer periphery of both the first fixing member 201 and the second fixing member 202. When clamping the first fixing member 201 and the second fixing member 202, the clamp 105 is limited by clamping at the limiting groove 205, thereby reducing the possibility of the clamp 105 detaching from the limiting component 200. At the same time, external force is gradually applied to the clamp 105, causing the clamp 105 to open slowly. Due to the elastic force of the spring 203, the clamp 105 does not detach from the limiting groove 205, while the first fixing member 201 and the second fixing member 202 open, making it convenient for medical staff to adjust the position of the inner tube.

[0034] In summary, the working principle of this solution is as follows:

[0035] When using this device, first, place the sleeve 102 on the end of the tube, then pass the inner tube through the sleeve 102 and adjust the extension length of the inner tube within the sleeve 102. Finally, place the limiting component 200 on the inner tube. Once the position of the inner tube is determined, move the limiting component 200 and press the clamp 105 to open it. Align the limiting groove 205 with the clamp head of the clamp 105, release the clamp 105, and under the elastic force of the torsion spring 104, the clamp 105 resets and clamps into the limiting groove 205. Inside, under the pressure of clamp 105, the first fixing member 201 and the second fixing member 202 are close to and fit against the inner tube, and the inner tube is fixed by the friction pad provided on the inner side, making it difficult for the inner tube to move due to accidental contact. When it is necessary to adjust the extension length of the inner tube, press the clamp 105 to open the clamp 105. At this time, the first fixing member 201 and the second fixing member 202 are separated under the action of spring 203. At this time, the position of the inner tube is moved. After the position of the inner tube is moved, the above steps are repeated.

[0036] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0037] Therefore, the above description is only a preferred embodiment of this application and is not intended to limit the scope of this application; that is, all equivalent modifications made in accordance with the scope of the claims of this application shall be within the protection scope of the claims of this application.
