Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a catheter slippage fixation device. Background Technology

[0002] In the medical field, catheter fixation plays a crucial role in the treatment of various diseases and patient rehabilitation. Whether during surgery or in the postoperative care stage, ensuring that the catheter is stably and accurately fixed in a specific location inside or on the patient's body is a key factor in ensuring the smooth progress of medical procedures and patient safety. The design and application of catheter fixation devices have always been an important direction in medical device research and development, and their performance directly affects the quality of medical care and the patient's treatment experience.

[0003] Most existing catheter fixation methods use simple adhesive tape or ordinary clamps. Adhesive tape relies solely on the adhesive to hold the catheter to the patient's skin, making it susceptible to damage from sweating, sebum secretion, and patient movement, which can weaken the tape's adhesion and cause the catheter to loosen or even slip out. While ordinary clamps can hold the catheter to some extent, their simple structure lacks adaptability and often fails to provide precise fixation based on the catheter's size and shape, leading to insecure fixation or excessive pressure and damage.

[0004] However, existing fixation methods have a significant problem: they cannot effectively address changes in catheter size and displacement during the fixation process. For example, when a patient is active, the catheter may be subjected to various external forces, resulting in slight movement or minor changes in size. Traditional fixation methods struggle to provide real-time, precise adaptive fixation, which greatly increases the risk of catheter slippage, posing potential safety hazards to the patient's treatment and adding difficulty and uncertainty to the work of medical staff. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a device for fixing catheters to prevent slippage, which aims to improve the problem that existing devices cannot effectively cope with changes in the size and displacement of the catheter during the fixing process, thus resulting in limited fixing effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for fixing a catheter to prevent slippage, comprising a fixing plate, a connecting block fixedly connected to one side of the outer wall of the fixing plate, a fixing block rotatably connected to the outer wall of the connecting block, an adjusting component inside the fixing block, a bandage fixedly connected to the upper surface of the fixing plate, a catheter attached to the lower surface of the bandage, and a fixing component provided on the upper surface of the fixing plate.

[0007] The fixing component includes a fixing base, the lower surface of which is fixedly connected to the upper surface of the fixing plate. A slot is opened inside the fixing base, and a telescopic rod is fixedly connected inside the fixing base. A spring is fixedly connected to one side of the outer wall of the telescopic rod, a support block is fixedly connected to one side of the outer wall of the spring, and a locking block is fixedly connected to one side of the outer wall of the support block.

[0008] Furthermore, the adjustment component includes a second connecting block, the outer wall of which is fixedly connected to the inside of the fixing block, an elastic band is fixedly connected to one side of the outer wall of the second connecting block, and a Velcro fastener is fixedly connected to one side of the outer wall of the elastic band.

[0009] Furthermore, the outer wall of the locking block is fixedly connected to the inside of the slot, and the locking block is used to limit the position of the conduit.

[0010] Furthermore, an anti-slip strip is fixedly connected to one side of the inner wall of the fixing seat, and the anti-slip strip is used to increase the friction between the guide tube and the fixing seat.

[0011] Furthermore, one side of the outer wall of the first connecting block is attached to one side of the outer wall of the second connecting block, and the first connecting block serves as a connector.

[0012] Furthermore, the lower surface of the conduit is attached to the upper surface of the fixing plate, and the fixing plate serves to provide support.

[0013] Furthermore, one side of the outer wall of the telescopic rod is fixedly connected to one side of the outer wall of the support block, and the telescopic rod serves to limit the movement of the spring.

[0014] Furthermore, the outer wall of the support block is slidably connected to the inside of the fixed seat, which serves to provide a stable mounting base for other internal components.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the guide tube slides along the outer wall of the locking block, thereby achieving the effect of inserting the guide tube into the empty slot. At this time, the movement of the guide tube causes the locking block to move, which in turn causes the telescopic rod to retract, thus achieving the effect of the spring contracting. Through the self-adjusting ability of the spring, the locking block fixes the guide tube. The fixing method, which combines a bandage and a fixing buckle, improves the stability of the fixation.

[0017] 2. In this utility model, an elastic band is connected to one end of the Velcro, and the elastic band is combined with the main body of the Velcro. By stretching or contracting the elastic band, the tightness of the Velcro can be adjusted, thereby enabling the fixation device to be flexibly adjusted according to the patient's actual situation, further improving the applicability of the device.

[0024] 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.

[0025] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a catheter slippage fixing device, comprising a fixing plate 1, which has stable and reliable support capabilities. A connecting block 2 is fixedly connected to one side of its outer wall, providing a stable connection point for connected components, thereby ensuring the integrity and stability of the entire device structure. A fixing block 3 is rotatably connected to its outer wall, and an adjustment component is provided inside the fixing block 3. A bandage 8 is fixedly connected to the upper surface of the fixing plate 1, possessing good flexibility and a certain binding force. A catheter 16 is attached to its lower surface, enabling the clamping of the catheter 16. It serves as a preliminary fixation and limiting element, preventing the guide tube 16 from moving freely on the fixing plate 1. A fixing assembly, including a fixing seat 9, is provided on the upper surface of the fixing plate 1. The lower surface of the fixing seat 9 is firmly fixed to the upper surface of the fixing plate 1, providing a stable mounting base for other internal components. A slot 15 is provided inside the fixing seat 9 to accommodate and install related components. A telescopic rod 10 is fixedly connected inside the fixing seat 9. The telescopic rod 10 can extend and retract within a certain range, providing precise displacement guidance and restriction for connected components. A spring 11 is fixedly connected to one side of its outer wall. 1. The spring 11 can provide a stable and adjustable elastic force by utilizing its own elastic deformation. A support block 12 is fixedly connected to one side of the outer wall of the spring 11. The support block 12 can effectively transmit and disperse the elastic force of the spring 11. A locking block 13 is fixedly connected to one side of its outer wall. The outer wall of the locking block 13 is fixedly connected to the inside of the slot 15. The locking block 13 can cooperate with other components to achieve precise fixation and limiting of the guide tube 16. An anti-slip strip 14 is fixedly connected to one side of the inner wall of the fixing seat 9. The anti-slip strip 14 effectively enhances the fixing plate 1 and the fixing seat 9 by increasing the friction between the fixing plate 1 and the guide tube 16 or other contact components. The stability and reliability of the conduit 16 during the process are ensured, and displacement of the conduit 16 due to insufficient friction is avoided. One side of the outer wall of connecting block 12 is attached to one side of the outer wall of connecting block 24. Connecting block 12 plays a key role in the connection, ensuring close cooperation and coordinated work between related components. The lower surface of the conduit 16 is attached to the upper surface of the fixing plate 1. One side of the outer wall of the telescopic rod 10 is fixedly connected to one side of the outer wall of the support block 12. The telescopic rod 10 plays a role in precisely limiting the movement of the spring 11, so that the extension and contraction direction and range of the spring 11 can be effectively controlled, thereby ensuring the stable operation of the entire fixing assembly.

[0026] Reference Figure 1 , Figure 2 and Figure 3The adjustment component includes a second connecting block 4, which serves as a connector. The outer wall of the second connecting block 4 is fixedly connected to the inside of the fixing block 3. The fixing block 3 is used to fix the first connecting block 2 and the second connecting block 4. An elastic band 5 is fixedly connected to one side of its outer wall. The elastic band 5 has good elasticity and tensile properties and can adapt to different tensile requirements to a certain extent. A Velcro 6 is fixedly connected to one side of its outer wall. The Velcro 6 has quick and convenient sticking and separating characteristics and can be used to achieve quick, efficient and stable fixing of the fixing plate 1, meeting the needs of quick installation and disassembly of the fixing device in actual use.

[0027] Working principle: Place the fixation plate 1 on a suitable part of the patient's body, usually near the outlet of catheter 16 or where catheter 16 needs to be fixed. Ensure that the fixation plate 1 fits tightly against the skin without obvious gaps or lifting. For some special areas, such as the arm or leg, it may be necessary to make appropriate adjustments according to the direction of catheter 16 and the patient's activity level, so that the position of the fixation plate 1 is convenient for fixing catheter 16 without affecting the patient's normal activities. Use the fixing device to fix catheter 16 to the fixation plate 1. Then, insert catheter 16 into the empty groove 15, ensuring that catheter 16 is in place and avoids loosening. Connect one end of connecting block 12 to the fixation plate 1. The connection points on the fixing plate 1 are connected to ensure a firm connection without any loosening. Based on the patient's comfort and the need for fixing the catheter 16, the self-adjusting spring 11 ensures that the fixing device can firmly fix the catheter 16 without being too tight and causing discomfort to the patient. After fixing, gently pull the catheter 16 to check whether the fixing device is firm and whether the catheter 16 shows any signs of loosening, displacement, or slippage. At the same time, observe the patient's comfort and ask if the patient feels any tightness or discomfort. If necessary, readjust it again. During use, medical staff should regularly check the fixing device for subsequent observation and maintenance.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
