Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of indwelling needle fixation, and in particular to an indwelling needle fixation bandage. Background Technology
[0002] Currently, the main methods for fixing indwelling needles include the sheathing structure and the wrapping structure. While the sheathing structure offers some convenience, its relatively fixed size makes it difficult to flexibly adapt to the differences in hand size among patients. For patients with larger or smaller hands, it cannot achieve a stable and comfortable fixation, and may even cause local complications. The wrapping structure, while allowing for some adjustment based on the patient's hand shape, can easily create a feeling of tightness due to its unidirectional pulling fixation method in actual use. Excessive wrapping not only causes discomfort to the patient and hinders blood circulation in the constricted area, but over time it may also cause skin damage and increase patient suffering.
[0003] Therefore, how to balance the stability and comfort of indwelling needle fixation is a technical problem that urgently needs to be solved. Utility Model Content
[0004] To balance the stability and comfort of indwelling needle fixation, this utility model provides an indwelling needle fixation bandage that can be used to fix indwelling needles on limbs of different sizes and has good comfort.
[0005] This utility model embodiment provides the following solution: an indwelling needle fixation bandage, the bandage comprising:
[0006] Finger sleeves are used to be worn on the thumbs of patients' limbs;
[0007] The finger sleeve has a first extension extending toward the back of the patient's limb and a second extension extending toward the palm of the patient's limb;
[0008] The first extension segment and / or the second extension segment are longer than the preset length, so that when the first extension segment and the second extension segment are connected, they are wrapped around the patient's limb at least once to fix the indwelling needle on the back of the limb.
[0009] In one alternative embodiment, the palm extension of the first extension and / or the second extension located in the palm of the limb has a waterproof structure.
[0010] In one alternative embodiment, the waterproof structure is a separately installed plastic strip or a plastic layer applied to the substrate of the bandage.
[0011] In one alternative embodiment, an anti-slip layer is provided on the plastic strip or plastic layer.
[0012] In one alternative embodiment, the bandage substrate is elastic self-adhesive gauze.
[0013] In one optional embodiment, the first extension segment has a first connecting portion at its end, and the second extension segment has a second connecting portion at its end; the first connecting portion and the second connecting portion are used to connect when the first extension segment and the second extension segment are wrapped around the patient's limb.
[0014] In one optional embodiment, the connection structure between the first connecting part and the second connecting part is a Velcro structure or a snap fastener structure.
[0015] In one alternative embodiment, the finger cot has a covering portion extending toward the wrist of the limb.
[0016] In one optional embodiment, the first extension segment is shorter than a first preset length, and the second extension segment is longer than a second preset length, so that the second extension segment wraps around the patient's limb twice and connects to the first extension segment.
[0017] In one alternative embodiment, the dorsal extension of the first and / or second extension is provided with a label layer.
[0018] Compared with the prior art, the indwelling needle fixation bandage of this utility model has the following advantages:
[0019] This utility model discloses an indwelling needle fixation bandage comprising a finger cot, which has a first extension extending towards the back of the patient's limb and a second extension extending towards the palm of the patient's limb. Since the first and / or second extensions are longer than a preset length, they can wrap around the patient's limb at least once when the first and second extensions connect. This technical solution involves wearing the finger cot over the patient's thumb and securing the indwelling needle on the back of the limb by wrapping it around the limb with the first and second extensions. It is applicable to indwelling needle fixation on limbs of different sizes. Furthermore, because the first and second extensions exert opposite pulling forces when fixing the indwelling needle, the finger cot does not tighten around the thumb due to unidirectional pulling, thus balancing the stability and comfort of the indwelling needle fixation.

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the embodiments of the present utility model.
[0026] This utility model's indwelling needle fixation bandage can be applied to the fixation of indwelling needles in the hands and feet. The following will use the fixation of indwelling needles in the hand as an example to specifically illustrate the technical solution proposed in this utility model. Please refer to... Figure 1 , Figure 1 This is a schematic diagram of the structure of an indwelling needle fixation bandage provided in an embodiment of the present invention. The indwelling needle fixation bandage includes a finger sleeve 1, which has a first extension section 2 extending towards the back of the patient's limb and a second extension section 3 extending towards the palm of the patient's limb. Both the first extension section 2 and the second extension section 3 can be configured as strip structures or as large sheet structures, as long as they can fix the indwelling needle 10 tightly against the back of the limb. Fixing the indwelling needle can prevent its tip displacement, thereby avoiding damage to blood vessels or internal tissues caused by the indwelling needle 10.
[0027] The finger cot 1 is worn over the patient's thumb 9. The finger cot 1 can have an open or closed structure; no specific limitation is made here. The finger cot 1 allows for initial positioning of the indwelling needle when it is secured with a bandage, preventing circumferential displacement of the bandage after the needle is secured. Figure 1 As shown, to accommodate different hand sizes and improve comfort, finger holes 11 can be made on the finger sleeve 1. When fixing the indwelling needle, the entire finger sleeve 1 is slipped over the thumb 9 of the hand, so that the entire finger sleeve 1 fits snugly against the thumb 9. The finger sleeve 1 can be made of a breathable elastic material, such as cotton or gauze.
[0028] When the bandage is used to secure an indwelling needle in a patient's foot, the first extension segment 2 extends towards the instep, and the second extension segment 3 extends towards the sole (or foot plate). When the bandage is used to secure an indwelling needle in a hand, the first extension segment 2 extends towards the back of the hand, and the second extension segment 3 extends towards the palm. The lengths of the first extension segment 2 and the second extension segment 3 can be set based on actual needs. The first extension segment 2 and / or the second extension segment 3 can be longer than a preset length. By connecting the first extension segment 2 and the second extension segment 3, the indwelling needle on the back of the limb can be covered. When connecting the first extension segment 2 and the second extension segment 3, it needs to be wrapped around the patient's limb at least once to secure the indwelling needle on the back of the limb.
[0029] It is understandable that the connection structure between the first extension segment 2 and the second extension segment 3 can be freely set according to actual needs. For example, it can be set as a rope structure. The rope can be tied to the corresponding tightness according to the size of the limb to fix the indwelling needle. When it is necessary to remove the indwelling needle, the rope can be untied to carry out the needle removal operation.
[0030] To improve the convenience of the bandage, the first extension segment 2 can be configured to be shorter than a first preset length, and the second extension segment 3 to be longer than a second preset length, so that the second extension segment 3 wraps around the patient's limb twice and connects to the first extension segment 2. Please refer to [link / reference]. Figure 2 , Figure 2 This diagram illustrates the first usage state of the bandage for securing an indwelling needle 10. When securing the indwelling needle 10, the finger cot 1 is placed over the thumb, with the first extension segment 2 pressed against the back of the hand, so that the needle tube of the indwelling needle 10 is positioned between the first extension segment 2 and the back of the hand. The second extension segment 3 wraps from the thenar eminence of the palm to the hypothenar eminence, continuing to the back of the hand to secure the indwelling needle. The second extension segment 3 then continues from the web between the thumb and index finger of the palm to the center of the palm, passing through the center of the palm, and then wraps from the hypothenar eminence to the back of the hand, connecting with the first extension segment 2, thus completing two loops of wrapping and securing the indwelling needle. This two-loop wrapping method increases the contact area between the bandage and the indwelling needle, ensuring reliable fixation.
[0031] Please continue reading. Figure 1 and Figure 2 To further improve the ease of fixing the indwelling needle 10, a first connecting part 5 can be provided at the end of the first extension segment 2, and a second connecting part 6 can be provided at the end of the second extension segment 3. The first connecting part 5 and the second connecting part 6 are used to connect the first extension segment 2 and the second extension segment 3 when they are wrapped around the patient's limb. The connection structure between the first extension segment 2 and the second extension segment 3 can be set as a Velcro structure. The Velcro structure has good self-adhesive properties, which makes it easy to adjust the tightness of the bandage when fixing the indwelling needle 10, and also facilitates the application of adhesive fixation.
[0032] When securing the indwelling needle 10 for children, a snap-fit structure can be used to connect the first extension section 2 and the second extension section 3. For example, multiple female snaps can be spaced apart along the length of the first connecting part 5, and a single female snap can be provided on the second connecting part 6. After the indwelling needle is wrapped and secured by the second extension section 3, the female snap can be pressed into the corresponding female snap to complete the connection between the first extension section 2 and the second extension section 3. The snap-fit structure can prevent children from tearing the bandage, causing the first extension section 2 and the second extension section 3 to separate, thus improving the reliability of the connection between the first extension section 2 and the second extension section 3.
[0033] It should be noted that the choice of bandage base material needs to comprehensively consider factors such as softness, breathability, and biocompatibility. Cotton or gauze can be chosen as the base material for the bandage, or elastic fibers or non-woven fabrics can be used. Elastic self-adhesive gauze can also be used; this type of material has good elasticity and stretchability, allowing it to stretch and contract with limb movement, providing a comfortable fit, and is less likely to cause a constricting feeling, which helps to secure the indwelling needle and prevent its displacement.
[0034] In practical applications, because the bandage is made of a flexible material, sweaty palms or handling objects can easily cause the bandage in the palm area to become wet and curl, which can easily breed bacteria. Furthermore, the wet and curled bandage, being a linear structure, can also cause a feeling of tightness, leading to discomfort when securing the indwelling needle. Therefore, in one specific embodiment, the palm extension of the first extension segment 2 and / or the second extension segment 3 is equipped with a waterproof structure. This waterproof structure prevents the palm extension from becoming wet and curled, further improving the comfort of securing the indwelling needle.
[0035] The waterproof structure can be a separately installed plastic strip, which is attached to the first extension section 2 and / or the second extension section 3. When preparing the bandage to install the plastic strip, the first extension section 2 and / or the second extension section 3 can be cut, and the plastic strip can be glued to the corresponding extension section. The plastic strip is made of an elastic and waterproof plastic material, such as a soft, skin-friendly plastic. Alternatively, the plastic strip can be designed as a hollow structure, fitted over the first extension section 2 and / or the second extension section 3, to prevent sweat or water from wetting the bandage.
[0036] The waterproof structure can also be a plastic layer 4 applied to the base material of the bandage. The plastic layer 4 can be applied to the outer side of the base material and the side of the base material closest to the palm. The plastic layer 4 effectively prevents sweat from the palm and any external moisture from penetrating into the bandage, while also increasing the strength of the bandage and preventing it from curling. The plastic layer 4 is applied directly to the base material, forming a unified whole with the bandage, making the waterproof structure less prone to displacement or detachment during use. The process of applying the plastic layer 4 to the base material is relatively mature, allowing for large-scale production and easy control of production costs. The plastic layer 4 has a certain degree of hardness, and when applied to the base material, its edge is spaced 1-3 mm from the edge of the base material to prevent the plastic layer 4 from scratching the skin or causing discomfort.
[0037] Since indwelling needles may need to be left in the patient's limb for several days, during which time items need to be retrieved, the use of a plastic band or plastic layer 4 could cause items to slip. Therefore, in one specific embodiment, the plastic band or plastic layer 4 is provided with an anti-slip layer. The anti-slip layer can be a raised dot matrix structure, or it can be set as raised or recessed anti-slip textures. By providing an anti-slip layer, items can be prevented from slipping due to the smooth plastic surface when the patient holds them, improving the convenience and safety of the patient in retrieving items.
[0038] In practical applications, since the finger sleeve 1 is worn on the thumb, if the sleeve length is too short or the thumb bone is prominent, there will be a noticeable feeling of tightness. Therefore, in one specific embodiment, the finger sleeve 1 has a covering portion 7 extending towards the wrist. Please refer to... Figure 3 , Figure 3 This is a schematic diagram of the second usage state of the bandage for securing the indwelling needle. The covering part 7 can wrap the bandage around the thenar eminence, increasing the contact area between the finger sleeve 1 and the hand, reducing the tightness when securing the indwelling needle, and improving the patient's comfort when securing the indwelling needle.
[0039] Furthermore, in this embodiment of the bandage, a label layer 8 is provided on the back extension section of the first extension section 2 and / or the second extension section 3 located on the back of the limb. Please continue reading. Figure 2 The label layer 8 can be laid on the substrate of the first extension section 2 and / or the second extension section 3. The patient's bed number, name and other information can be recorded through the label layer 8, which makes it easier for medical staff to verify the patient's identity when administering intravenous infusion.
[0040] The technical solution provided in this embodiment of the utility model has at least the following technical effects or advantages:
[0041] This utility model discloses an indwelling needle fixation bandage comprising a finger cot, which has a first extension extending towards the back of the patient's limb and a second extension extending towards the palm of the patient's limb. Since the first and / or second extensions are longer than a preset length, they can wrap around the patient's limb at least once when the first and second extensions connect. This technical solution involves wearing the finger cot over the patient's thumb and securing the indwelling needle on the back of the limb by wrapping it around the limb with the first and second extensions. It is applicable to indwelling needle fixation on limbs of different sizes. Furthermore, because the first and second extensions exert opposite pulling forces when fixing the indwelling needle, the finger cot does not tighten around the thumb due to unidirectional pulling, thus balancing the stability and comfort of the indwelling needle fixation.
