Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a drainage tube fixing device. Background Technology

[0002] In clinical medicine, chest and abdominal drainage tubes are core devices for postoperative exudate drainage, and their fixation effectiveness directly affects the quality of patient recovery. Traditional fixation methods typically involve wrapping the drainage tube with medical tape and attaching it to the body surface. However, with advancements in medical technology and evolving patient care needs, existing techniques have revealed significant shortcomings, specifically in the following aspects:

[0003] 1. Insufficient fixed reliability

[0004] Traditional medical tapes are affected by sweat and sebum secretions on the patient's skin, causing their adhesion to rapidly decrease over time. This is especially true after surgery when there is frequent activity or in high-temperature environments, leading to problems such as tape curling at the edges and complete detachment. When the external drainage tube is subjected to external force, the tape cannot effectively buffer the mechanical stress, causing direct pulling on the wound. This not only causes pain and discomfort but may also lead to displacement or even dislodgement of the drainage tube, increasing the risk of a second surgery.

[0005] 2. Low ease of operation and low nursing efficiency.

[0006] When securing drainage tubes, medical staff need to repeatedly adjust the angle and tightness of the tape wrapping, making each operation time-consuming and requiring frequent dressing changes post-operatively. For minimally invasive surgical drainage tubes with smaller diameters (such as those after laparoscopy), multiple layers of tape can easily cause the tube to bend and deform, affecting drainage efficiency. In addition, adhesive residue can easily remain on the surface of the tape in contact with the skin, and the cleaning process may damage the fragile post-operative skin.

[0007] 3. Limitations of existing improvement technologies

[0008] Although the drainage tube fixator represented by patent CN201120156981.0 improves the fixation strength through the hinged clamp structure, it still has significant defects: the miniature locking design requires too high operational precision, and it is difficult for medical staff to quickly complete the locking action when wearing gloves.

[0009] In summary, existing drainage tube fixation techniques struggle to balance the triple demands of clinical safety, ease of operation, and patient comfort, necessitating the development of a novel fixation device with adaptive adhesion capabilities and support for rapid assembly and disassembly. Utility Model Content

[0010] The present invention provides a drainage tube fixing device to solve the above-mentioned problems.

[0011] The technical solution of this utility model is implemented as follows:

[0012] A drainage tube fixing device includes a fixing tube body sleeved over a drainage tube. A second notch is formed on the side wall of the fixing tube body to facilitate insertion of the drainage tube. A locking nut is threadedly connected to the outside of the fixing tube body to push and clamp the drainage tube. A third notch is formed on the locking nut to match the second notch. The lower end of the fixing tube body is fixed to an adhesive layer. The lower surface of the adhesive layer is coated with an adhesive layer, and a release film is adhered to the surface of the adhesive layer. Ears extending beyond the adhesive layer are formed at the edge of the release film. A first notch is formed on the adhesive layer to allow the tube to pass through the second notch. The width of the first notch does not exceed the width of the second notch. The fixing tube body and the locking nut are made of medical transparent plastic.

[0013] Furthermore, the adhesive layer includes an antibacterial hemostatic layer and a transparent and breathable adhesive tape layer. The outer circle of the antibacterial hemostatic layer and the inner circle of the transparent and breathable adhesive tape layer are heat-fused together. The antibacterial hemostatic layer is made of antibacterial hemostatic material, and the transparent and breathable adhesive tape layer is a medical transparent film.

[0014] Furthermore, the adhesive layer is a sensitive adhesive, and the adhesive layer is coated on the lower surface of the transparent and breathable adhesive tape layer.

[0015] Furthermore, the opening angle of the second notch is 1 / 5 to 1 / 3 of the circumference of the fixed tube.

[0016] Furthermore, the fixed tube body includes an externally threaded tube body that is vertically fixed to the adhesive layer. Several expansion grooves are formed on the outer circumference of the externally threaded tube body, and an elastic body is fixed on the inner wall of the externally threaded tube body.

[0017] Furthermore, the locking nut includes an inner cone with a conical inner cavity, and an inner thread formed on the inner wall of the inner cone to mate with the external thread on the external threaded tube. The locking nut has inwardly inclined guide openings on both sides corresponding to the third notch.

[0018] Furthermore, the upper end of the inner cone is integrally formed with a heightened protective sleeve, and the sum of the heights of the inner cone and the heightened protective sleeve is not less than the height of the external threaded tube body, and the edge of the heightened protective sleeve is blunted.

[0019] The beneficial effects of this utility model by adopting the above technical solution are as follows: after the drainage tube passes through the notch, it can be inserted into the fixing device, which makes it easy to install the fixing device on the drainage tube. The drainage tube can be quickly fixed by turning the locking nut, which is simple, convenient and easy to operate; the antibacterial hemostatic layer can accelerate the hemostasis of the wound and reduce bacterial infection; during nursing, the disinfectant can come into contact with the wound through the expansion groove, which is convenient for daily disinfection.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0031] like Figures 1-7As shown, a drainage tube fixing device includes a fixing tube body 4 sleeved on the outside of the drainage tube. A second notch 7 is formed on the side wall of the fixing tube body 4 to facilitate the insertion of the drainage tube. The opening angle of the second notch 7 is 1 / 5-1 / 3 of the circumference of the fixing tube body 4, allowing the drainage tube to pass through the side wall of the fixing tube body 4 and reach the interior of the fixing tube body 4. The fixing tube body 4 includes an externally threaded tube body 41 vertically fixed to an adhesive layer 1. Several expansion grooves 43 are formed on the outer circumference of the externally threaded tube body 41. An elastic body 42, made of silicone or latex, is fixed to the inner wall of the externally threaded tube body 41. The expansion grooves 43 penetrate the elastic body 42 to allow it to... The tube is cut into multiple strips. A locking nut 5 is installed on the outside of the fixed tube 4 via a threaded connection. This locking nut 5 is used to clamp the drainage tube. A third notch 8 is formed on the locking nut 5 to match the second notch 7. The opening angle of the third notch 8 is 1 / 5 to 1 / 3 of the circumference of the locking nut 5. The locking nut 5 includes an inner cone 51 with a conical inner cavity. An inner thread 52 is formed on the inner wall of the inner cone 51 to mate with the external thread on the external threaded tube 41. The locking nut 5 has inwardly inclined guide openings 54 on both sides corresponding to the third notch 8. The maximum diameter of the guide openings 54 is larger than the diameter of the external threaded tube 41 when it is not under force. The diameter of the inner cone 51 is such that when the inner cone 51 is turned clockwise, the external threaded tube 41 can be driven to contract inward, causing the elastic body 42 to press against the outer wall of the drainage tube and clamp the drainage tube, preventing the drainage tube from loosening. The guide bevel 54 allows the external threaded tube 41 located at the third notch 8 to tilt along the guide bevel 54 during the rotation of the inner cone 51, making it easier for the inner thread 52 to be engaged with the external threaded tube 41. This prevents the external threaded tube 41 located at the third notch 8 from being unable to re-enter the inner cone 51 after losing the compression of the inner cone 51 and completing the clamping of the drainage tube. The fixing tube 4 and the locking nut 5 are made of medical transparent plastic. Made of a material that allows medical staff to visually observe the condition of the drainage tube installation site through the fixed tube body 4 and locking nut 5, and to promptly understand the wound condition. The lower end of the fixed tube body 4 is fixed to the adhesive layer 1. The lower surface of the adhesive layer 1 is coated with an adhesive layer 2, and a release film 3 is adhered to the surface of the adhesive layer 2. The edge of the release film 3 is formed with an ear 31 that extends beyond the adhesive layer 1. In use, the release film 3 is peeled off through the ear 31, and then the adhesive layer 2 is placed close to the skin to adhere the adhesive layer 1 to the patient's skin. The adhesive layer 1 is formed with a first notch 6 that extends through the tube to the second notch 7. The width of the first notch 6 does not exceed the width of the second notch 7.

[0032] In this embodiment, the adhesive layer 1 includes an antibacterial hemostatic layer 11 and a transparent and breathable adhesive tape layer 12. The outer circle of the antibacterial hemostatic layer 11 and the inner circle of the transparent and breathable adhesive tape layer 12 are heat-fused together. The antibacterial hemostatic layer 11 is made of the antibacterial hemostatic material described in the patent with publication number CN112891602A. This material uses nano-silver ions to achieve antibacterial effect and zeolite material to achieve hemostasis, thereby accelerating hemostasis and antibacterial treatment of the wound at the drainage tube installation site and avoiding bacterial infection of the wound. The transparent and breathable adhesive tape layer 12 is a medical transparent film, which is convenient for observing the bleeding status and timely detection of potential risks. The adhesive layer 2 is a sensitive adhesive and is coated on the lower surface of the transparent and breathable adhesive tape layer 12. The antibacterial hemostatic layer 11 is a non-sensitive adhesive and can be directly contacted with the skin for better hemostasis and antibacterial treatment.

[0033] In this embodiment, the upper end of the inner cone 51 is integrally formed with a heightened protective sleeve 53. The sum of the heights of the inner cone 51 and the heightened protective sleeve 53 is not less than the height of the external threaded tube 41. The edge of the heightened protective sleeve 53 is blunted. After the drainage tube is fixed, the end of the external threaded tube 41 is hidden inside the heightened protective sleeve 53. The heightened protective sleeve 53 contacts the drainage tube and the clothing. The blunting treatment can prevent damage to the clothing.

[0034] The working principle of this utility model is as follows: In use, the locking nut 5 is rotated so that the second notch 7 and the third notch 8 are aligned. Then, the adhesive layer 1 is folded over to increase the width of the first notch 6. The drainage tube is passed through the first notch 6, the second notch 7 and the third notch 8 to reach the inside of the fixed tube body 4. Then, the release film 3 is removed and the adhesive layer 1 is pasted on the patient's wound. The locking nut 5 is rotated to bring it closer to the adhesive layer 1. During the rotation, the locking nut 5 pushes the external thread tube body 41 to gradually deform and clamp the drainage tube to complete the fixation of the drainage tube and prevent the drainage tube from loosening.
