Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to a skin fixation device for the external end of a dialysis catheter used in nephrology nursing. Background Technology

[0002] In nephrology clinical treatment, hemodialysis and peritoneal dialysis are the core means of maintaining the lives of patients with renal failure. As the key pathway connecting the patient's body to the dialysis equipment, the stable placement of the external end of the dialysis catheter is directly related to the safety and continuity of dialysis treatment. The external end of the dialysis catheter needs to be left on the patient's skin surface for a long time. It is necessary to avoid displacement, twisting or even dislodgement caused by the patient's daily activities, turning over or other movements, and to reduce friction damage at the contact point between the catheter and the skin, so as to provide a continuous and reliable pathway for dialysis treatment.

[0003] Patients with renal failure need to rely on dialysis treatment for a long time. The fixation of the external end of the dialysis catheter directly affects the treatment efficiency and the patient's quality of life. If the external end of the dialysis catheter is not properly fixed during the patient's daily activities, it is easily affected by external forces such as pulling and collision. This may not only cause the catheter to shift or fall out, leading to dialysis interruption, but may also increase the risk of skin redness, swelling, ulceration, and infection due to repeated friction and pressure between the catheter and the skin. In severe cases, it may even endanger the patient's life.

[0004] Traditional devices used to fix the external end of dialysis tubing often rely on adhesive tape. Long-term use can easily cause skin allergies and irritation. Furthermore, the adhesiveness of the tape is easily affected by skin oils and sweat, leading to loosening and detachment, failing to achieve a stable and reliable fixation effect. At the same time, the breathability design of the parts of the device that come into contact with the skin is insufficient, which can easily lead to stuffiness and sweat accumulation in the skin with long-term contact, further increasing the risk of infection. Summary of the Invention

[0005] Traditional devices for fixing the external end of dialysis catheters often rely on adhesive tape, which can easily cause skin allergies and irritation with long-term use. Furthermore, the adhesive strength of the tape is easily affected by skin oils and sweat, leading to loosening and detachment, failing to achieve a stable and reliable fixation. Additionally, the insufficient breathability of the area in contact with the skin can cause stuffiness and sweat buildup with prolonged contact, further increasing the risk of infection. The purpose of this invention is to provide a dialysis catheter external end fixation device for nephrology nursing.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A dialysis catheter skin external fixation device for nephrology nursing includes a fixation plate with a tube body passing through the center of the fixation plate and a binding component on the fixation plate. The binding component can bind the fixation plate passing through the tube body to the patient without the need for tape.

[0013] Optionally, the breathable component includes a breathable cavity formed in a fixed plate, a breathable hole formed in the breathable cavity, the breathable hole being located on the side closest to the patient, a through hole communicating with the outside in the breathable cavity, and an airbag fixedly installed on the fixed plate, the airbag communicating with the breathable cavity.

[0014] Optionally, the protective component includes a slide groove formed on a fixed plate, a protective cover slidably mounted on the slide groove and limited by a limiting component, and a locking plate that cooperates with the protective cover is fixedly mounted on the fixed plate.

[0015] Optionally, the limiting component includes a fixed plate fixedly mounted on a fixed plate, a pin slidably mounted on the fixed plate, a third spring fixedly mounted on the pin, one end of the third spring away from the pin fixedly mounted on the fixed plate, and a socket for engaging with the pin on the protective cover.

[0016] Optionally, the locking plate is provided with a disinfection component, the disinfection component includes a storage cylinder fixedly installed on the locking plate, a nozzle fixedly installed on the storage cylinder, a corrugated pipe that cooperates with the protective cover is provided in the sliding groove, a connecting pipe is fixedly installed on the corrugated pipe, and the end of the connecting pipe away from the corrugated pipe is fixedly connected to the storage cylinder.

[0017] Optionally, a mounting plate is fixedly installed inside the nozzle, a fourth spring is fixedly installed on the mounting plate, a sliding ring is fixedly installed on the fourth spring, the sliding ring is slidably connected to the inner wall of the nozzle, a rotating shaft is rotatably installed inside the sliding ring, a nozzle is fixedly installed on the rotating shaft, and an arc-shaped flow channel is provided inside the nozzle.

However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0040] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. It should also be noted that, to make the embodiments more comprehensive, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some well-known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0041] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0042] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0043] It is understood that the meanings of “on”, “above”, and “above” in this invention should be interpreted in the broadest manner, such that “on” means not only “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” means not only “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0044] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.

[0045] like Figures 1 to 8 As shown, this embodiment of the invention provides a skin fixation device for the external end of a dialysis catheter used in nephrology nursing, including a fixation plate 10, a through-tube 11 disposed at the center of the fixation plate 10, a binding component 20 disposed on the fixation plate 10, the binding component 20 can bind the fixation plate 10 through the tube 11 to the patient without tape; a ventilation component 40 is disposed inside the fixation plate 10, the ventilation component 40 is used for ventilation at the contact point between the fixation plate 10 and the patient; a protective component 50 is disposed on the fixation plate 10, the protective component 50 is used for housing and protecting the tube 11;

[0046] The fixing plate 10 serves as the core load-bearing component, with the dialysis tubing 11 at its center, achieving initial positioning of the dialysis tubing. The binding component 20 uses a non-adhesive physical binding method to firmly attach the fixing plate 10 to the patient's skin surface, avoiding skin irritation or detachment issues caused by adhesive tape. The ventilation component 40 is located inside the fixing plate 10, enabling air circulation channels to be formed between the fixing plate 10 and the patient's skin, reducing the stuffiness caused by prolonged skin contact. The protective component 50 is installed on the fixing plate 10 to store and shield the exposed portion of the dialysis tubing passing through the tubing 11, preventing external collisions, dust contamination, or tubing scattering, avoiding tubing displacement or damage, and ensuring the safety of the dialysis access.

[0047] like Figure 2 and Figure 4 As shown, the binding component 20 includes a pair of movable connectors 21 connected by a buffer connection component 30. Each movable connector 21 is fixedly mounted with a strap 22, and the strap 22 is provided with Velcro 23.

[0048] The binding component 20 consists of a pair of movable connectors 21, which are connected by a buffer connection component 30, allowing the movable connectors 21 a certain degree of freedom of movement. Each movable connector 21 is fixedly fitted with a binding strap 22, and the Velcro 23 on the strap 22 allows for quick opening, closing, and securing. In use, the binding strap 22 is wrapped around the patient's body, and the tightness is adjusted and locked using the Velcro 23. The coordinated action of the two movable connectors 21 ensures that the binding angle of the strap 22 better conforms to the patient's body contours. The tightness of the binding strap 22 is adjustable to fit patients of different body types, and it is not easily loosened after binding, improving stability.

[0049] like Figure 4 As shown, the buffer connection assembly 30 includes a first mounting cavity 31 formed on the fixed plate 10, a first spring 32 fixedly installed in the first mounting cavity 31, a movable rod 33 fixedly installed on the first spring 32, the movable rod 33 being slidably connected to the inner wall of the first mounting cavity 31, a connecting ball 34 fixedly installed on the movable rod 33, and a movable cavity 35 that cooperates with the connecting ball 34 is formed in the movable connector 21;

[0050] The connecting ball 34 at the other end of the movable rod 33 is embedded in the movable cavity 35 of the movable connector 21, allowing the movable connector 21 to rotate flexibly around the connecting ball 34. When the patient's movement causes the strap 22 to be pulled, the first spring 32 will produce elastic deformation to buffer the pulling stress. At the same time, the movable connector 21 adjusts its angle through the connecting ball 34 to adapt to the patient's range of motion. The buffering effect of the spring can counteract the pulling force, preventing the dialysis tube from being excessively pulled due to the patient's movement, reducing the risk of catheter displacement and dislodgement. The multi-angle rotation capability of the movable connector 21 improves the adaptability of the device to the patient's body and reduces the pressure at the binding site.

[0051] like Figure 4 As shown, a second mounting cavity 36 is provided in the fixed plate 10, and a second spring 37 is fixedly installed in the second mounting cavity 36. The end of the second spring 37 away from the second mounting cavity 36 is fixedly connected to the movable connecting member 21.

[0052] When the movable connector 21 is pulled by the strap 22 or subjected to external force from the patient's movement, the second spring 37 and the first spring 32 form a double elastic buffer structure. The second spring 37 further absorbs the external force through its own expansion and contraction deformation, and at the same time, it assists in limiting the range of motion of the movable connector 21 to prevent the movable connector 21 from swinging excessively. The double spring buffer design enhances the tensile strength of the binding component 20, disperses the impact of external force on the fixing plate 10, and makes the fixation more stable; at the same time, it limits the excessive movement of the movable connector 21 to prevent the strap 22 from loosening, and further ensures the fixation effect of the dialysis tube.

[0053] like Figure 6 As shown, the fixed disk 10 has a first friction groove 38 formed longitudinally and a second friction groove 39 formed transversely.

[0054] When the fixing plate 10 is in contact with the patient's skin, the first friction groove 38 and the second friction groove 39 can increase the friction between the fixing plate 10 and the skin, reduce the slippage of the device caused by the patient's movement or skin sweating; sweat flows out along the anti-slip groove 51 to reduce the feeling of stuffiness on the skin, reduce the probability of skin inflammation, and improve wearing comfort.

[0055] like Figure 5 As shown, the breathable component 40 includes a breathable cavity 41 opened in the fixed plate 10, a breathable hole 42 opened in the breathable cavity 41, the breathable hole 42 is located on the side closer to the patient, a through hole 43 opened in the breathable cavity 41 to communicate with the outside, and an air bag 44 is fixedly installed on the fixed plate 10, the air bag 44 is connected to the breathable cavity 41.

[0056] The airbag 44 on the fixed plate 10 is connected to the ventilation chamber 41. When the patient bends over and squeezes the airbag 44, the gas inside the airbag 44 can be blown to the skin surface through the ventilation chamber 41 and the ventilation hole 42, accelerating local air circulation. When the airbag 44 is released, outside air enters through the through hole 43, the ventilation chamber 41 and the ventilation hole 42, forming a gas circulation. The active airbag 44 ventilation structure enhances the air circulation efficiency of the skin contact area, quickly removes sweat and moisture, significantly improves breathability, further protects the skin and reduces the risk of infection.

[0057] like Figure 3 As shown, the protective component 50 includes a slide groove 51 formed on the fixed plate 10, a protective cover 52 that is limited by a limiting component 60 is slidably installed on the slide groove 51, and a locking plate 53 that cooperates with the protective cover 52 is fixedly installed on the fixed plate 10.

[0058] The locking plate 53 on the fixed plate 10 cooperates with the protective cover 52. When the protective cover 52 slides along the slide groove 51 to the designated position, the locking plate 53 and the protective cover 52 cooperate to completely cover the exposed part of the dialysis tubing. When the dialysis tubing needs to be used, the restriction of the limiting component 60 is released, and the tubing can be exposed by sliding the protective cover 52 along the slide groove 51. The sliding protective cover 52 is easy to operate and can quickly achieve the protection and exposure of the dialysis tubing. The protective cover 52 can effectively block external collisions, dust and contaminants, protect the tubing interface and exposed part, and at the same time prevent the tubing from becoming scattered, thus improving the safety of use.

[0059] like Figure 3 As shown, the limiting component 60 includes a fixed plate 61 fixedly installed on the fixed plate 10, a pin 62 slidably installed on the fixed plate 61, a third spring 63 fixedly installed on the pin 62, one end of the third spring 63 away from the pin 62 fixedly installed on the fixed plate 61, and a socket 64 that mates with the pin 62 is provided on the protective cover 52.

[0060] When the protective cover 52 slides to the protective position, the pin 62 is inserted into the socket 64 of the protective cover 52 under the action of the third spring 63, thus locking and fixing the protective cover 52. When unlocking is required, pull the pin 62 outward to compress the third spring 63, causing the pin 62 to disengage from the socket 64, and the protective cover 52 can then slide. The spring-driven pin 62 limit structure ensures reliable locking and effectively prevents the protective cover 52 from sliding accidentally, ensuring the protective effect. The unlocking operation is simple, requires no complicated tools, and improves the convenience of dialysis operations.

[0061] like Figure 7As shown, a disinfection component 70 is provided on the locking plate 53. The disinfection component 70 includes a storage cylinder 71 fixedly installed on the locking plate 53, a nozzle 72 fixedly installed on the storage cylinder 71, a corrugated pipe 73 that cooperates with the protective cover 52 is provided in the sliding groove 51, a connecting pipe 74 is fixedly installed on the corrugated pipe 73, and the end of the connecting pipe 74 away from the corrugated pipe 73 is fixedly connected to the storage cylinder 71.

[0062] When the sliding protective cover 52 closes, it compresses the bellows 73, forcing the gas inside into the storage cylinder 71. This increases the pressure inside the storage cylinder 71, causing the disinfectant liquid to be sprayed out from the nozzle 72 to disinfect the dialysis tube interface and surrounding area. Disinfection is achieved through the sliding action of the protective cover 52, eliminating the need for additional disinfection steps and improving nursing efficiency. The disinfectant liquid is sprayed directly onto key areas, making disinfection more precise, reducing the risk of infection, and achieving integrated protection and disinfection.

[0063] like Figure 8 As shown, a mounting plate 75 is fixedly installed inside the nozzle 72, a fourth spring 76 is fixedly installed on the mounting plate 75, a sliding ring 77 is fixedly installed on the fourth spring 76, the sliding ring 77 is slidably connected to the inner wall of the nozzle 72, a rotating shaft 78 is rotatably installed inside the sliding ring 77, a nozzle 79 is fixedly installed on the rotating shaft 78, and an arc-shaped flow channel 710 is provided inside the nozzle 79;

[0064] When the pressure inside the storage cylinder 71 pushes the disinfectant liquid into the nozzle 72, the liquid impacts the arc-shaped flow channel 710 of the nozzle 79, causing the nozzle 79 to rotate around the rotating shaft 78. At the same time, the fourth spring 76 pushes the sliding ring 77 to move along the inner wall of the nozzle 72, so that the spraying range of the nozzle 79 covers the dialysis tube interface and surrounding area. The rotating nozzle 79, in conjunction with the movement of the sliding ring 77, achieves uniform spraying of the disinfectant liquid, improving the disinfection effect. No additional power is required; the automatic rotating spraying is achieved by the pressure of the disinfectant liquid. The structure is ingenious and the operation is convenient.

[0065] The specific workflow of the technical solution provided by this invention is as follows:

[0066] The tube body 11 passes through the center of the fixation plate 10, and the fixation plate 10 is attached to the catheter outlet on the patient's skin;

[0067] Pull the strap 22 on the movable connector 21, wrap it around the patient's body and lock it in place with Velcro 23. During the binding process, the movable connector 21 adapts to the patient's body contour and buffers the tensile stress through the cooperation of the connecting ball 34, the first spring 32, and the second spring 37. The first friction groove 38 and the second friction groove 39 on the fixed plate 10 enhance the friction with the skin and prevent the device from sliding.

[0068] During wear, the ventilation chamber 41, ventilation hole 42 and through hole 43 of the ventilation component 40 form a natural ventilation channel. When the patient bends over and squeezes the air bag 44, the air circulation can be actively accelerated to avoid skin stuffiness.

[0069] In non-dialysis mode, the protective cover 52 slides along the slide groove 51 to cover the tube body 11 and the exposed part of the dialysis tube. The pin 62 is inserted into the insertion hole 64 under the action of the third spring 63, and the protective cover 52 is locked to achieve protection. When the protective cover 52 is slid, the corrugated tube 73 is squeezed so that the disinfectant liquid in the storage cylinder 71 is evenly sprayed onto the tube interface through the rotating nozzle 79 to complete the automatic disinfection.

[0070] During dialysis, pull out the pin 62 to unlock the protective cover 52, slide it open along the slide groove 51 to expose the dialysis tube interface, and then the connection operation can be performed.

[0071] When changing or adjusting the device periodically, loosen the Velcro 23 and remove the strap 22 to disassemble the device. After checking the condition of the skin and catheter, reinstall and secure it.

[0072] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
