Description

Technical Field

[0001] This utility model relates to the field of medical assistive devices technology, and in particular to a multifunctional medical external fixator. Background Technology

[0002] Catheter fixation techniques are mainly divided into two categories: external fixation and internal fixation. External fixation typically involves using tape, bandages, clamps, or specialized fixation devices to secure the catheter to the patient's body surface for emergency hemostasis or to protect open wounds. Internal fixation involves directly fixing the catheter to internal structures, such as through sutures or anchoring. However, traditional fixation devices may loosen or become unstable after prolonged use, increasing the risk of catheter dislodgement; they can also easily irritate the patient's skin or compress the wound; or, if the bandage is too tight, it may restrict the patient's movement or impair blood circulation. Utility Model Content

[0003] The technical problem solved by this invention is that traditional fixation devices may loosen and become unstable after being fixed to the human body for a long time, increasing the risk of catheter dislodgement; they may also easily irritate the patient's skin; or the bandage may be too tight, preventing the patient from moving normally or affecting blood circulation, which may cause skin damage or even further expansion and necrosis of the wound.

[0004] To solve the above-mentioned technical problems, the present invention provides a multifunctional medical external fixator, comprising:

[0005] A soft silicone sheet, wherein a through hole for a conduit to pass through is provided in the middle of the soft silicone sheet, and a through cut extends from one of the through holes to the side of the soft silicone sheet. An installation groove is also provided on the side of the soft silicone sheet facing the human body, and fixing grooves are provided at multiple corners of the soft silicone sheet.

[0006] An elastic fixing band has multiple fixing ends at both ends, and a fixing hook is movably installed in each fixing end. The fixing hook hooks the fixing groove to connect the elastic fixing band to the soft silicone plate.

[0007] The dressing sheet is detachably installed in the mounting groove and comes into contact with the human body, and the dressing sheet has an auxiliary opening whose position corresponds to the through hole and the incision.

[0008] Optionally, the side of the soft silicone sheet is also provided with an arc-shaped guide groove, which is connected to the cut and the cut is connected to the through hole.

[0009] Optionally, the depth of the mounting groove is equal to or slightly less than the thickness of the dressing sheet.

[0010] Optionally, the soft silicone sheet has rounded corners at multiple edges.

[0011] Optionally, the diameter of the through hole is 0.05cm to 0.15cm.

[0012] Optionally, the fixing hook is connected to the fixing end via a fixing pin, and the fixing hook can rotate around the fixing end with the fixing pin as the center.

[0013] Optionally, the elastic fixing band is a single strip with multiple fixing ends at both ends.

[0014] Optionally, the elastic fixing band is a multi-strip structure, with each strip having an end forming the fixing end.

[0015] Optionally, the dressing sheet has a 6-8 layer gauze structure, and the edges of the dressing sheet and the auxiliary opening are stitched together.

[0016] Optionally, the dressing sheet may be filled with gauze or hydrogel dressing and aerogel in the space formed by the suture edge.

[0017] The beneficial effects of this utility model's technical solution are:

[0018] The fixator of this invention can firmly fix the catheter using the friction of the soft silicone plate, preventing the catheter from shifting or falling off. At the same time, the soft silicone plate increases the force-bearing area, which can reduce pressure and damage to the patient's skin. The elastic fixation band can prevent the fixator from being too tight or rubbing, reducing skin irritation. The elastic fixation band is flexible in style and can be applied to different parts of the patient's body. The fixator has a simple structure and is easy to operate, which can improve work efficiency. In an emergency, it can also be used as a hemostatic and pressure bandaging tool. After dealing with the emergency, it can continue to be used as a treatment auxiliary tool. Attached Figure Description

[0028] Please see Figure 1 and Figure 2The image shows an embodiment of a multifunctional medical external fixator, comprising a soft silicone plate 1. When a catheter needs to be fixed, a through hole 11 is provided in the center of the soft silicone plate 1 for the catheter to pass through. A through incision 12 extends from one end of the through hole 11 to the side of the soft silicone plate 1. An installation groove 14 is also provided on the side of the soft silicone plate 1 facing the human body. Fixing grooves 15 are provided at multiple corner positions of the soft silicone plate 1. An elastic fixing band 2 has multiple fixing ends 21 at each end. Fixing hooks 22 are movably installed in the fixing ends 21, hooking the fixing grooves 15 to connect the elastic fixing band 2 to the soft silicone plate 1. A dressing sheet 3 is detachably installed in the installation groove 14 and contacts the human body. The dressing sheet 3 has auxiliary openings 31 corresponding to the positions of the through hole 11 and the incision 12.

[0029] In this embodiment, the side of the soft silicone plate 1 is also provided with an arc-shaped guide groove 13, which is connected to the cut 12, and the cut 12 is connected to the through hole 11.

[0030] In this embodiment, the depth of the mounting groove 14 is equal to or slightly less than the thickness of the dressing sheet 3. Multiple corners of the soft silicone plate 1 are rounded. The diameter of the through hole 11 is 0.05cm to 0.15cm, preferably 0.1cm.

[0031] In this embodiment, the fixing hook 22 is connected to the fixing end 21 via the fixing nail 23, and the fixing hook 22 can rotate around the fixing end 21 with the fixing nail 23 as the center.

[0032] In this embodiment, as Figure 1 As shown, the elastic fixing belt 2 is a single strip with multiple fixing ends 21 at both ends.

[0033] In this embodiment, as Figure 2 As shown, the elastic fixing band 2 is a multi-strip structure with each strip having a fixed end 21 at its end.

[0034] In this embodiment, as Figure 3 As shown, the dressing sheet 3 has a structure of 6 to 8 layers of gauze, and there are stitches 32 around the dressing sheet 3 and around the auxiliary opening 31; the space 33 formed by the stitches 32 in the dressing sheet 3 is filled with gauze or hydrogel dressing and aerogel.

[0035] The following description will further illustrate the characteristics and functions of this utility model.

[0036] The fixation device in this embodiment aims to reduce the risk of skin damage, increase patient comfort, and reduce the risk of unplanned extubation. This invention is characterized by its high adaptability, low allergenicity, and ease of operation. It also assists in routine emergency bandaging.

[0037] like Figure 1As shown, the fixation device includes a conventional elastic fixation strap 2 or a conventional elastic bandage (usually purple) and a red soft silicone plate 2.

[0038] like Figure 2 As shown, there is a triangular elastic bandage 2 or a triangular elastic bandage (usually purple and not distinguished by left or right); to adapt to different parts of the body, appropriate elastic bandages (including but not limited to the above styles) can be selected. The elastic band is adjustable in length to adapt to the limbs or torso; the conventional elastic bandage has a metal fixing hook on each side and a small rubber band (not shown) below it. The catheter is placed between the two and the rubber band is fastened to the fixing hook to fix the catheter; the same applies to other types of elastic bandages.

[0039] like Figure 3 The image shows a specialized dressing pad, a square, sterilized cotton pad measuring 7.8 x 7.8 cm. This sterilized cotton pad is individually packaged for daily replacement. It is approximately 6-8 layers thick with stitched edges around the perimeter and opening. The central opening is approximately 0.1 cm for the catheter to pass through (the opening proportions are exaggerated in the image for clarity). The filler is either hydrogel or aerogel (same size as above), which helps maintain skin moisture around the catheter insertion site, offering good skin-friendliness and low allergenicity. Its material properties allow it to adhere tightly to the skin after absorbing sweat, further preventing slippage of the fixing material. Hydrogel has good permeability and diffusion, allowing for the addition of skin-care or local anesthetic and analgesic medications in special circumstances. Aerogel can act as a drug carrier, utilizing its porous structure and good biocompatibility to adsorb a large number of drug molecules and achieve slow release, enabling targeted drug delivery, improving efficacy, and reducing damage to normal tissues.

[0040] The red soft silicone sheet has a fixing groove at each of its four corners, connecting to the U-shaped fixing hooks of the elastic bandage. The U-shaped hooks and elastic bandages are rotatable for optimal positioning. (The U-shaped hooks can be made of alloy with a rust-resistant coating for increased durability). The soft silicone sheet is primarily made of soft silicone, allowing it to bend and conform to the skin and torso. Its skin-contacting surface is smooth and has mounting grooves for adding or replacing dressings, increasing comfort and meeting cleaning needs. Its outer surface is frosted. The soft silicone sheet and elastic bandages are washable, sterilizable, and reusable, and should be replaced according to their material lifespan. The dressing is disposable. The elastic bandages are available in multiple sizes or extendable versions to meet the needs of different individuals and treatment areas.

[0041] The reason for choosing the fixator in this embodiment is that reducing the use of tape or bandages to fix the catheter may lead to insecure fixation due to patient sweating or secretions, thereby increasing the risk of catheter dislodgement. Reducing certain fixation materials may irritate the patient's skin or wound, especially during prolonged fixation or repeated changes.

[0042] Overly tight or complex fixation methods may restrict a patient's range of motion and freedom of movement, affecting their comfort. Some fixation methods, if too tight, may impair blood circulation and require periodic loosening to avoid potential complications. Using specific fixation devices and disposable materials may increase costs, impacting the patient's financial burden.

[0043] The advantages of the fixator in this embodiment are as follows:

[0044] 1. The fixator uses friction to firmly secure the catheter, preventing it from shifting or falling off. At the same time, the fixation plate increases the force-bearing area, reducing pressure and damage to the patient's skin. In emergencies, limb ligation can save time and reduce the risk of rebleeding or secondary infection due to insecure fixation.

[0045] 2. Comfort: The design takes patient comfort into consideration, utilizing elastic bandages to avoid excessive tightness or friction. The bandage material and its mesh structure are highly breathable, reducing skin irritation and potential complications.

[0046] 3. Adaptability: The fixator should be able to adapt to different sizes and types of catheters, as well as different patients' anatomy and skin conditions. The silicone plate itself is flexible and has strong conformability;

[0047] 4. Ease of operation: The design of the fixation device should facilitate quick and accurate installation and adjustment by medical staff to improve work efficiency.

[0048] 5. Ease of maintenance and replacement: The fastener should be easy to clean and maintain, and parts or the entire fastener should be easily replaceable when necessary.

[0049] 6. Biocompatibility: The materials used should have good biocompatibility to reduce allergic reactions and other adverse biological events. For example: 1. For open wounds, hydrogels are excellent wet dressing materials due to their high water content, biocompatibility, and structure similar to human macromolecules. They can provide a suitable moist environment for the wound, help clear wound exudate, prevent infection, and promote tissue regeneration. 2. For larger and deeper local tissue wounds: Aerogels have pore sizes and structures similar to human tissues, which can mimic the structure and function of the natural extracellular matrix, providing a good growth environment for cells and regulating cell growth and differentiation; they can also provide the supporting structure required for cell growth and tissue regeneration, aiding wound healing and tissue repair.

[0050] 7. Durability: The fastener has sufficient strength and durability to withstand wear and tear during daily use.

[0051] 8. Multifunctionality: The fixator design includes additional functions, such as a dressing module for easy replacement to reduce catheter contamination during use; and an elastic fixation band module suitable for multiple users and body parts, which can be independently disassembled and replaced for ease of use. After catheter removal, normal leak-free dressings, cotton pads, etc., can be used, utilizing the device's own elastic pressure to assist in hemostasis. In daily life, it can also be used as a tension-reducing device for emergency hemostasis when treating wounds; or when bandaging local wounds, it can protect the wound and dressing. The large silicone plate area can reduce or disperse the possibility of wound re-bleeding or pain caused by bumps and knocks in daily life.

[0052] 9. Scalability: The fixator design should allow for the addition or removal of fixation modules as needed to accommodate catheters of different lengths and locations, as well as wounds. Materials can be selected or customized according to individual needs: for example, replacing soft silicone plates with more supportive and protective elastic ceramic plastics, or more malleable medical resins. Different dressings can be selected at different stages of open wound treatment or healing to assist in treatment, promote healing, and improve prognosis.

[0053] The method of using the fixator in this embodiment is as follows: Have the patient lie on the elastic fixation band and wait for final fixation; place the sterile cotton pad with the hole in the center aligned with the catheter outlet (or, wrap around the stoma), then cover it, cover it with the silicone pressure plate, place the catheter in a comfortable position (align the silicone plate and dressing with the center of the wound or the bleeding site); fix the elastic fixation band and adjust it to a suitable length.

[0054] In summary, the fixator of this invention can firmly fix the catheter using the friction of the soft silicone plate, preventing the catheter from shifting or falling off. At the same time, the soft silicone plate increases the force-bearing area, which can reduce pressure and damage to the patient's skin. The elastic fixation strap can prevent the fixator from being too tight or rubbing, reducing skin irritation. The elastic fixation strap is flexible in style and can be applied to different parts of the patient's body. The fixator has a simple structure, is easy to operate, and can improve work efficiency.

[0055] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
