Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary appliances, and particularly relates to a pressure ulcer prevention and fixation device for an infusion port. Background Art

[0002] An infusion port, also known as an implantable central venous catheter system, is a completely implantable closed venous infusion system. It is mainly used to provide a safe, convenient, and reliable venous access for patients who need long-term or frequent intravenous infusions, especially suitable for chemotherapy patients, patients with long-term parenteral nutrition support, and patients with chronic diseases who need long-term infusion treatment. The infusion port mainly consists of an injection port, a venous catheter, a non-invasive needle, and other auxiliary structures. The infusion port is a safe, convenient, and reliable long-term intravenous infusion device, which provides great convenience for patients who need long-term or frequent infusions.

[0003] Patent document CN221771079U discloses a fixation device for an arm infusion port. "The device includes: a cover body, which has a through hole at the top for covering the installation position of the infusion port on the arm; a fixing belt, which is pulled out from the side of the bottom of the cover body for winding around the arm to fix the cover body. This device can fix the infusion port on the patient's arm, avoid displacement and flipping, and while ensuring the normal use of the infusion port, avoid the pain brought to the patient by the reset of the flipped infusion port." However, this infusion port fixation device causes the patient's skin to be under pressure for a long time, increasing the friction and irritation to the skin, resulting in low injection comfort for the patient and further increasing the incidence of pressure ulcers. Summary of the Invention

[0004] The purpose of the present invention is to provide a pressure ulcer prevention and fixation device for an infusion port to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A pressure ulcer prevention and fixation device for an infusion port, characterized by comprising:

[0007] An injection fixation cover;

[0008] The outer side of the bottom end of the injection fixation cover is fixedly connected with a saline arc storage frame, and the outer end of the saline arc storage frame is fixedly connected with a pressure ulcer prevention and care arc frame;

[0009] The inner side of the pressure ulcer prevention and care arc frame is slidably connected with a lifting conduction arc plate. The bottom end of the lifting conduction arc plate is fixedly connected with a lifting transmission rod, and the bottom end of the lifting transmission rod is fixedly connected with a docking pressure plate. A saline seepage hole is opened through the top end of the lifting conduction arc plate, and a magic tape cleaning and wiping cotton pad is detachably connected to the bottom end of the lifting conduction arc plate.

[0010] Preferably, pressing and lifting holes are formed through the tops of the pressure ulcer prevention nursing arc frames, and the lifting transmission rods penetrate the inner sides of the pressing and lifting holes. Miniature dampers are fixedly connected to the inner top walls of the pressure ulcer prevention nursing arc frames. Pressing and resetting spring columns are fixedly connected to the inner top walls of the pressure ulcer prevention nursing arc frames, and the pressing and resetting spring columns are sleeved on the outer sides of the miniature dampers. The bottom ends of the pressing and resetting spring columns are fixedly connected to the tops of the lifting conduction arc plates.

[0011] Preferably, a central positioning seat is fixedly connected to the inner wall of the top end of the injection fixing cover. A positioning operation puncture hole is formed through the top end of the central positioning seat, and a winged atraumatic needle is inserted through the inner side of the positioning operation puncture hole.

[0012] Preferably, an injection port seat is detachably connected to the bottom of the injection fixing cover. A contact base is fixedly connected to the bottom end of the injection port seat. An injection liquid storage tank is formed at the center of the top end of the injection port seat. A puncture diaphragm is fixedly connected to the inner wall of the top end of the injection liquid storage tank. An intravenous catheter is fixedly connected to the surface of the injection port seat.

[0013] Preferably, a conduction and transmission port is formed through between the physiological saline arc-shaped storage frame and the pressure ulcer prevention nursing arc frame. An outer sliding seat is fixedly connected to the outer end of the lifting conduction arc plate. Guide sliding grooves are formed on the inner walls of the pressure ulcer prevention nursing arc frames, and the outer sliding seat is slidably connected to the guide sliding grooves. A saline adding cylinder is fixedly connected to the top end of the physiological saline arc-shaped storage frame.

[0014] Preferably, a transparent dressing outer guiding seat is fixedly connected to the surface of the pressure ulcer prevention nursing arc frame. Dressing tension adhesive grooves are formed at the top ends of the transparent dressing outer guiding seats. An extended inclined seat is fixedly connected to the outer end of the transparent dressing outer guiding seat. Friction protrusions are fixedly connected to the top ends of the extended inclined seats. A cushioning and decompression pad is fixedly connected to the bottom end of the extended inclined seat.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) A pressure ulcer prevention nursing arc frame is fixedly connected to the outer end of the saline arc-shaped storage frame. After the infusion port injection fixing cover is stably installed, medical staff press the docking pressing plate, causing the lifting conduction arc plate to move downward inside the pressure ulcer prevention nursing arc frame. The saline in the saline arc-shaped storage frame is stored in the pressure ulcer prevention nursing arc frame through the conduction outlet, and flows into the magic tape cleaning and wiping cotton pad through the saline seepage holes and is absorbed by it. The magic tape cleaning and wiping cotton pad cleans the skin outside the implanted position of the patient's infusion port, removing dirt and sweat, keeping the skin dry and clean. The pressure ulcer prevention nursing arc frame reduces the risk of pressure ulcers caused by long-term skin compression. The magic tape cleaning and wiping cotton pad wiping the affected skin with saline reduces friction and irritation to the skin, improving the patient's comfort and further reducing the incidence of pressure ulcers. The automatic delivery of saline reduces the chance of medical staff directly contacting the patient's skin and reduces the risk of cross-infection.

[0017] (2) The bottom end of the pressing and resetting spring column is fixedly connected to the top end of the lifting conduction arc plate. When the infusion port injection fixing cover is in use, the micro-damper and the pressing and resetting spring column can effectively prevent the lifting conduction arc plate from moving downward too fast under excessive force, avoiding direct pressure on the implanted part of the patient's injection port seat and reducing the risk of pressure ulcer occurrence. This is particularly important for patients who need to use the infusion port for a long time or frequently. The elasticity and resistance of the damper and the pressing and resetting spring column ensure that the lifting conduction arc plate will not cause any damage to the infusion port during normal rebound, guaranteeing the long-term use effect and safety of the infusion port, helping to extend the service life of the infusion port, and reducing failures and damages caused by improper use.

[0018] (3) A transparent dressing outer guiding seat is fixedly connected to the surface of the pressure ulcer prevention nursing arc frame. The transparent dressing outer guiding seat and its extended inclined seat at the outer end guide the transparent dressing for pasting. The friction protrusions on the upper surface of the extended inclined seat increase the contact area between the dressing and the extended inclined seat to ensure the pasting stability, reducing the adhesion area between the transparent dressing and the patient's skin while ensuring the stability during the use of the injection fixing cover, preventing the transparent dressing from slipping or shifting during injection, ensuring the accuracy and safety of injection. The guiding of the extended inclined seat enables the transparent dressing to more closely cover the injection fixing cover, reducing the direct adhesion area between the transparent dressing and the patient's skin and reducing the risk of skin discomfort or injury caused by improper pasting. The decompression pad disperses pressure, reducing the pressure on the skin at the implanted part of the injection port seat, effectively preventing the occurrence of pressure ulcers, and further enhancing the comfort of the patient during use.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1:

[0029] Please refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 as shown, an anti-pressure ulcer fixation device for an infusion port, comprising:

[0030] Injection fixing cover 1;

[0031] The outer side of the bottom end of the injection fixing cover 1 is fixedly connected with an arc-shaped saline storage frame 3, and the outer end of the arc-shaped saline storage frame 3 is fixedly connected with a pressure ulcer prevention nursing arc frame 4;

[0032] The inner side of the pressure ulcer prevention nursing arc frame 4 is slidably connected with a lifting conduction arc plate 20. The bottom end of the lifting conduction arc plate 20 is fixedly connected with a lifting transmission rod 17. The bottom end of the lifting transmission rod 17 is fixedly connected with a docking pressing plate 18. A saline seepage hole 22 is formed through the top end of the lifting conduction arc plate 20. The bottom end of the lifting conduction arc plate 20 is detachably connected with a magic tape cleaning and wiping cotton pad 23.

[0033] After the infusion port injection fixing cover 1 is stably installed, medical staff press the docking pressing plate 18. The lifting transmission rod 17 is stressed to push the lifting conduction arc plate 20. The lifting conduction arc plate 20 moves downward inside the pressure ulcer prevention nursing arc frame 4. The physiological saline in the physiological saline arc-shaped storage frame 3 is stored in the pressure ulcer prevention nursing arc frame 4 through the conduction and delivery port 15, and flows into the magic tape cleaning and wiping cotton pad 23 through the saline seepage hole 22 and is absorbed by it. The magic tape cleaning and wiping cotton pad 23 cleans the skin outside the infusion implantation position of the patient, removing dirt and sweat.

[0034] The pressure ulcer prevention nursing arc frame 4 reduces the risk of pressure ulcers caused by long-term skin compression. The magic tape cleaning and wiping cotton pad 23 wipes physiological saline on the affected skin to reduce friction and irritation to the skin. When the lifting conduction arc plate 20 is not working, its outer end blocks the conduction and delivery port 15. The physiological saline in the physiological saline arc-shaped storage frame 3 is stored in the pressure ulcer prevention nursing arc frame 4 through the conduction and delivery port 15 and flows into the magic tape cleaning and wiping cotton pad 23 through the saline seepage hole 22, which can quickly moisten the wiping cotton pad, facilitating medical staff to clean the patient's skin. The magic tape design makes the wiping cotton pad easy to replace and clean, ensuring a continuous and effective cleaning effect and preventing cross-infection between patients. Physiological saline has cleaning and antibacterial effects, can remove dirt and sweat on the skin, reduce bacterial growth, and thus keep the skin dry and clean. The soft material and fitting design of the cleaning and wiping cotton pad can clean the skin more carefully, avoiding omission. Integrating the functions of physiological saline storage, delivery, and wiping simplifies the operation process of medical staff. Medical staff only need to press the docking pressing plate 18 to achieve the delivery of physiological saline and the cleaning of the skin, improving work efficiency and helping to improve the quality of medical care.

[0035] Embodiment 2:

[0036] Please refer to Figure 1 、 Figure 4 、 Figure 5 and Figure 6As shown in the figure, pressing and lifting holes 16 are formed through the top of the pressure ulcer prevention nursing arc frame 4, and the lifting transmission rod 17 runs through the inside of the pressing and lifting holes 16. Miniature dampers 6 are fixedly connected to the inner top walls of the pressure ulcer prevention nursing arc frame 4. Pressing and reset spring columns 19 are fixedly connected to the inner top walls of the pressure ulcer prevention nursing arc frame 4, and the pressing and reset spring columns 19 are sleeved outside the miniature dampers 6. The bottom ends of the pressing and reset spring columns 19 are fixedly connected to the top ends of the lifting conduction arc plates 20;

[0037] A conduction and transmission port 15 is formed through between the physiological saline arc-shaped storage frame 3 and the pressure ulcer prevention nursing arc frame 4. An outer sliding seat 21 is fixedly connected to the outer end of the lifting conduction arc plate 20. Guide sliding grooves 28 are formed in the inner walls of the pressure ulcer prevention nursing arc frame 4, and the outer sliding seat 21 is slidably connected to the guide sliding grooves 28. A saline adding cylinder 14 is fixedly connected to the top end of the physiological saline arc-shaped storage frame 3.

[0038] The dampers and pressing and reset spring columns 19 connected to the top end of the lifting conduction arc plate 20 inside the pressure ulcer prevention nursing arc frame 4 ensure the normal rebound of the lifting conduction arc plate 20 while slightly buffering the cleaning and pressing pressure of medical staff, preventing the lifting conduction arc plate 20 from moving downward too fast due to excessive force, causing pressure ulcers at the implantation site of the patient's injection port seat 2, avoiding direct compression on the implantation site of the patient's injection port, reducing the risk of pressure ulcer occurrence, which is particularly important for patients who need to use the infusion port for a long time or frequently;

[0039] The elasticity and resistance of the miniature dampers 6 and the pressing and reset spring columns 19 ensure that the lifting conduction arc plate 20 will not cause any damage to the infusion port during normal rebound, guaranteeing the long-term use effect and safety of the infusion port, helping to extend the service life of the infusion port, reducing failures and damages caused by improper use. The miniature dampers 6 and the pressing and reset spring columns 19 enable medical staff to feel a slight buffering effect when cleaning or pressing the infusion port, reducing the operation difficulty and physical consumption, improving the operation efficiency of medical staff, reducing accidental risks and errors during the operation, and improving the overall safety of the entire infusion process. The miniature dampers 6 and the pressing and reset spring columns 19 enable the lifting conduction arc plate 20 to maintain stability and accuracy during rebound, and at the same time facilitate the daily maintenance and cleaning work of medical staff.

[0040] Embodiment 3:

[0041] Please refer to Figures 1 to 4 As shown in the figure, a physiological saline arc-shaped storage frame 3 is fixedly connected to the outer bottom of the injection fixing cover 1. A pressure ulcer prevention nursing arc frame 4 is fixedly connected to the outer end of the physiological saline arc-shaped storage frame 3. A central positioning seat 8 is fixedly connected to the inner top wall of the injection fixing cover 1. A positioning operation puncture hole 9 is formed through the top of the central positioning seat 8, and a wingless non-damaging needle 7 is inserted through the inside of the positioning operation puncture hole 9;

[0042] The bottom of the injection fixing cover 1 is detachably connected to an injection port base 2. The bottom end of the injection port base 2 is fixedly connected to a contact base 12. At the center position of the top end of the injection port base 2, an injection liquid storage tank 10 is provided. On the inner wall of the top end of the injection liquid storage tank 10, a puncture diaphragm 11 is fixedly connected. On the surface of the injection port base 2, a venous catheter 13 is fixedly connected.

[0043] The injection port base 2 is implanted in the subcutaneous tissue of the chest or upper arm area, facilitating puncture and connection to the infusion device. The venous catheter 13 is a slender and flexible catheter with good elasticity and biocompatibility. One end of the catheter is connected to the injection port base 2, and the other end passes through the subcutaneous tissue and enters the central vein position such as the junction of the superior vena cava and the right atrium, avoiding irritation and damage to the peripheral veins. The wingless non-damaging needle 7 is used to puncture the injection port base 2 for infusion.

[0044] During use, medical staff move the injection fixing cover 1 to the position of the patient's injection port base 2 and press the injection fixing cover 1. The injection fixing cover 1 positions the injection port base 2. The transparent dressing is pasted in the dressing tension adhesive groove 24 of the transparent dressing outer guide seat 5 outside the transparent dressing to realize the pasting and limiting of the injection fixing cover 1. Medical staff pass the wingless non-damaging needle 7 through the positioning operation puncture hole 9 in the central positioning seat 8 to ensure that the wingless non-damaging needle 7 is vertically inserted downward into the puncture diaphragm 11 in the injection port base 2. The liquid medicine is delivered into the injection liquid storage tank 10, and the injection liquid medicine in the injection liquid storage tank 10 is directly delivered to the central vein through the venous catheter 13.

[0045] Example 4:

[0046] Please refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 7 As shown in

[0047] On the surface of the pressure ulcer prevention nursing arc frame 4, a transparent dressing outer guide seat 5 is fixedly connected. At the top ends of the transparent dressing outer guide seats 5, dressing tension adhesive grooves 24 are provided. At the outer ends of the transparent dressing outer guide seats 5, extended inclined seats 25 are fixedly connected. At the top ends of the extended inclined seats 25, friction protrusions 26 are fixedly connected. At the bottom ends of the extended inclined seats 25, cushioning decompression pads 27 are fixedly connected.

[0048] The transparent dressing outer guide seat 5 and the extended inclined seats 25 at its outer end guide the pasting of the transparent dressing. The friction protrusions 26 on the upper surface of the extended inclined seats 25 increase the contact area between the dressing and the extended inclined seats 25 to ensure the pasting stability, reduce the adhesion area between the transparent dressing and the patient's skin while ensuring the stability of the injection fixing cover 1 during use, prevent the transparent dressing from slipping or shifting during the injection process, and ensure the accuracy and safety of the injection.The guidance of the extended inclined seat 25 allows the transparent dressing to be more closely covered on the injection fixing cover 1, reducing the direct adhesion area between the transparent dressing and the patient's skin, and reducing the risk of skin discomfort or damage caused by improper adhesion. The padded pressure relief pad 27 disperses the pressure and reduces the pressure on the skin at the implantation site of the injection port seat 2, effectively preventing the occurrence of pressure sores and further enhancing the comfort of use for patients. The transparent dressing outer guide seat 5 and its extended inclined seat 25 enable the transparent dressing to be more easily and accurately adhered to the injection fixing cover 1, reducing the difficulty of operation and improving the pasting efficiency. The friction protrusion 26 on the upper surface of the extended inclined seat 25 increases the contact area between the dressing and the extended inclined seat 25, thereby enhancing the stability of the adhesion and reducing the skin adhesion area and the risk of pressure sores.

[0049] Working principle: First, the medical staff moves the injection fixing cover 1 to the injection port seat 2 of the patient, presses the injection fixing cover 1, and the injection fixing cover 1 positions the injection port seat 2. The transparent dressing is pasted in the dressing tension sticking groove 24 of the transparent dressing outer guide seat 5 to achieve the pasting limit of the injection fixing cover 1. The friction protrusion 26 on the upper surface of the extended inclined seat 25 increases the contact area between the dressing and the extended inclined seat 25 to ensure the pasting stability. The cushion pressure relief pad 27 disperses the pressure and reduces the pressure on the skin at the implantation site of the injection port seat 2.

[0050] The medical staff presses the docking pressing plate 18, and the lifting transmission rod 17 is forced to push the lifting conductive arc plate 20, and the lifting conductive arc plate 20 moves downward inside the anti-pressure sore nursing arc frame 4. The physiological saline in the saline arc storage frame 3 is stored in the anti-pressure sore nursing arc frame 4 through the conductive inlet 15, and flows through the saline seepage hole 22 to the Velcro cleaning wiping cotton pad 23 and is absorbed by it. The Velcro cleaning wiping cotton pad 23 cleans the skin outside the patient's infusion implantation position, removes dirt and sweat, and keeps the skin dry and clean. The damper and the pressure-driven reset spring column 19 connected to the top of the lifting conductive arc plate 20 in the anti-pressure sore nursing arc frame 4 ensure that the lifting conductive arc plate 20 rebounds normally, and at the same time slightly buffers the cleaning pressing pressure of the medical staff, preventing the lifting conductive arc plate 20 from being subjected to excessive force and moving downward too quickly, causing pressure sores at the implantation site of the patient's injection port seat 2;

[0051] After the skin outside the implantation site of the patient's injection port 2 is cleaned, the medical staff will pass the butterfly-wing non-damaged needle 7 through the positioning operation puncture hole 9 in the central positioning seat 8, ensuring that the butterfly-wing non-damaged needle 7 is input downward and penetrates the puncture diaphragm 11 in the injection port 2, and the medicine is transported to the injection reservoir 10. The injection medicine in the injection reservoir 10 is directly transported to the central vein through the intravenous catheter 13.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
