TECHNICAL FIELD

[0001] The present application relates to the technical field of clinical nursing, in particular to a venous indwelling needle fixing band. BACKGROUND

[0002] In the field of clinical nursing, when the elderly, children, obese people or patients with unclear consciousness indwell venous needles, the needle head is prone to fall off or shift due to reasons such as skin relaxation, inconvenience in movement or weak self-protection ability, thereby causing complications, which poses a major challenge to nursing work. At the same time, the state of the needle eye needs to be observed in time during the nursing process to ensure the safety of infusion.

[0003] In clinical practice, ordinary bandages or dressings are often used to fix venous indwelling needles, which serve to fix the indwelling needle on the patient's limb to prevent the needle head from moving. This type of fixing method is a conventional means of fixing venous indwelling needles, which provides a basis for understanding for subsequent innovative fixing methods.

[0004] In the prior art, ordinary elastic bandages or dressings are used to directly wrap and fix venous indwelling needles. Taking an elastic bandage as an example, the structure is an elastic band-shaped fabric, which is wrapped around the limb where the indwelling needle is located when in use, and the indwelling needle is fixed by the elastic contraction force of the bandage. However, this scheme has obvious shortcomings: on the one hand, it is not convenient to observe the skin condition at the needle eye, such as whether it is red and swollen or exudes liquid; on the other hand, the tightness of the bandage is difficult to control accurately, and too tight may affect blood circulation, and too loose may not play an effective fixing role, especially for special groups with loose skin and frequent movement, the fixing effect is not good, and the risk of needle head falling off and shifting is high.

[0005] In view of the above problems, there is an urgent need for a venous indwelling needle fixing band. SUMMARY

[0007] Technical scheme In order to achieve the above object, the present application is realized by the following technical scheme: A venous indwelling needle fixing band, comprising: a fixing band made of elastic fabric, the fixing band is used for fixing the venous indwelling needle; an observation window is arranged in the middle of the fixing band, the observation window is used for observing the skin condition to facilitate the treatment of redness, exudation or abnormal bleeding; first fixing members are arranged at both ends of the fixing band for fixedly connecting the fixing band to the limbs in an openable and closable manner, the first fixing members are used for fixing the both ends of the fixing band into a cylindrical shape; a joint fixing part is arranged obliquely above the observation window, the middle of the joint fixing part is fixed to the fixing band, second fixing members are arranged at both ends of the joint fixing part for fixedly connecting the both ends of the joint fixing part in an openable and closable manner, the joint fixing part is used for fixing the joint of the indwelling needle to avoid the pulling caused by the shaking of the joint.

[0008] Further, the first fixing member is a magic tape, comprising a hook surface and a fuzzy surface, the hook surface and the fuzzy surface are arranged on the inner side and the outer side of the both ends of the fixing band respectively, or are arranged on the outer side and the inner side of the both ends of the fixing band respectively.

[0009] Further, the observation window is arranged in a rectangular shape, and the edges are processed by edge folding.

[0010] Further, the size of the observation window is 4 cm in length and 3 cm in width.

[0011] Further, the second fixing member is a bayonet suitable for fixing a positive pressure joint.

[0012] Further, the joint fixing part is a strip-shaped cloth loop, and the size is 3 cm in length and 1 cm in width.

[0013] Further, the second fixing member is a magic tape.

[0014] Further, the size of the fixing band is 15-25 cm in length and 9 cm in width, and the fixing band is divided into three specifications of S, M and L, and the elastic fabric is suitable for different limb sizes.

[0015] Beneficial effects The present application has the following beneficial effects: (1) By arranging the observation window, the nursing staff can directly observe the skin condition at the needle eye without unfastening the fixing band, so that the real-time monitoring and timely treatment of the abnormality are realized.

[0016] (2) By arranging the elastic fabric of the fixing band, the fixing band can adapt to different limb sizes, provide uniform contraction force, and effectively prevent the indwelling needle from falling off or shifting.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figs. 1-2 The present invention provides a technical solution: a fixation strap for an indwelling intravenous needle, characterized in that it includes: a fixation strap 1 made of elastic fabric, the fixation strap 1 being used to fix the indwelling intravenous needle; An observation window 2 is provided in the middle of the fixing strap 1. The observation window 2 is used to observe the skin condition to facilitate the treatment of abnormal redness, swelling, oozing or bleeding. The two ends of the fixing strap 1 are provided with first fixing members 3 for fixing the fixing strap 1 to the limb in an openable and closable manner. The first fixing members 3 are used to fix the two ends of the fixing strap 1 into a cylindrical shape. A connector fixing part 4 is provided diagonally above the observation window 2. The middle part of the connector fixing part 4 is fixed to the fixing band 1. The two ends of the connector fixing part 4 are provided with second fixing parts 41 for opening and closing and fixing the two ends of the connector fixing part 4 together. The connector fixing part 4 is used to fix the connector of the indwelling needle and avoid the pulling caused by the shaking of the connector.

[0028] In practice, the preparation stage after puncture After the patient completes the intravenous catheter insertion procedure, the nursing staff first covers the puncture site with a medical transparent dressing to ensure that the dressing completely covers the puncture site and is well sealed.

[0029] Next, prepare fixation strap 1, and select the appropriate size and length of fixation strap 1 according to the patient's limb circumference.

[0030] Application of fixing belt 1 adjustment stage Gently wrap the fixation strap 1 around the patient's limb, aligning the observation window with the transparent dressing area, ensuring that the observation window and the transparent dressing are completely aligned to guarantee clear observation.

[0031] During the wrapping process, slowly adjust the tightness of the fixation band 1: it should be such that a finger can be inserted between the bandage and the limb to ensure that blood circulation is not obstructed, while ensuring that the fixation band 1 fits tightly against the skin and that the intravenous catheter does not move significantly within the fixation band 1, thereby achieving reliable fixation.

[0032] Real-time observation and nursing stage After fixation, nursing staff can observe the transparent dressing and skin condition at the injection site through observation window 2 at any time.

[0033] If any abnormalities such as redness, swelling, oozing, or bleeding are found, they can be addressed immediately through the observation window, such as changing the dressing or adjusting the position of the indwelling needle. If the condition is normal, regular check-ups can be performed through observation window 2, such as every 2 hours. This avoids the need to frequently untie the bandage, reducing irritation to the patient and the risk of the indwelling needle dislodging.

[0034] A connector fixing part 4 is provided diagonally above the observation window 2.

[0035] The observation window 2 is located in the middle of the fixing strap 1, and has a rectangular opening (4cm long and 3cm wide). The edges are finished to ensure durability. The connector fixing part 4 is located diagonally above the observation window 2. It is a strip of cloth loop that is 3cm long and 1cm wide. It is opened and closed by the second fixing part 41 (such as Velcro).

[0036] The obliquely upward setting of the connector fixing part 4 optimizes the typical orientation of the indwelling venous catheter: the catheter tube bends to the right and is set at the obliquely upward on the right side, and the catheter tube bends to the left and is set at the obliquely upward on the left side. This allows the catheter of the indwelling venous catheter to naturally bypass the observation window 2 from the side and below, rather than vertically covering the observation area. This effectively avoids the needle or catheter obstructing the field of vision, ensuring that nursing staff can directly observe abnormal conditions such as redness, swelling, and exudation at the puncture site through the observation window 2 without removing the fixing strap.

[0037] The obliquely positioned upper part of the connector fixing part 4 ensures the real-time monitoring function of the observation window 2 through spatial avoidance, solving the problem of needles or catheters obstructing the field of vision in traditional fixation; the position of the connector fixing part 4 is ergonomic, reducing the bending tension of the catheter and improving the fixation stability; the overall structure, together with the elastic fabric of the fixation strap 1 (available in multiple sizes such as S, M, and L) and the adjustment capability of the first fixing component 3, adapts to different limb sizes and significantly reduces the risk of displacement and dislodgement.

[0038] When the connector of the indwelling intravenous catheter is fixed at the connector fixing part, the connector of the indwelling intravenous catheter should be facing upwards, which also makes it easier to connect the connector of the indwelling intravenous catheter next time.

[0039] Adjustable capability of the first fastener 3: Taking Velcro as an example, the tightness can be adjusted by changing the sticking position of the hook side and the loop side.

[0040] Furthermore, the first fastener 3 is a Velcro fastener, including a hook side and a rough side, which are respectively located on the inner and outer sides of both ends of the fastening strap 1, or respectively located on the outer and inner sides of both ends of the fastening strap 1.

[0041] In practice, the hook and loop sides of the Velcro are firmly attached to the elastic fabric at both ends of the fixing strap 1 through high-frequency welding or sewing processes, ensuring that it will not fall off after multiple opening and closing.

[0042] The fixation strap 1 is made of a fabric with good elasticity. When it wraps around the limb and is fixed by the first fixing member 3, the elasticity of the fabric itself will provide continuous slight pressure, which not only ensures the stability of the fixation, but also avoids affecting the blood circulation of the limb due to being too tight.

[0043] The flexible opening and closing design achieved by the first fastener 3 allows medical staff to quickly put on and remove the fastener 1, facilitating frequent checks of puncture sites or nursing procedures.

[0044] Meanwhile, the cylindrical fixing method, compared to traditional tape application, avoids the irritation and damage to the patient's skin caused by repeated application and tearing of tape, thus improving the safety and comfort of use.

[0045] Furthermore, the observation window 2 is rectangular in shape, with the edges finished using a finishing process.

[0046] In practice, the observation window 2 is designed in a rectangular shape. The rectangular observation window 2 makes it easy to align with the transparent dressing area of ​​the indwelling intravenous needle, providing a clear field of view and ensuring that nursing staff can directly observe the condition of the needle site.

[0047] The edges of the observation window 2 are finished with a finishing process. The finishing process prevents the fabric from fraying by sewing or heat cutting, enhances the durability and safety of the observation window 2, and avoids rough edges that may irritate the skin.

[0048] Furthermore, the size of observation window 2 is 4cm long and 3cm wide.

[0049] In practice, the size of the observation window 2 is set to 4 cm in length and 3 cm in width. The size is precisely designed to match the transparent dressing area of ​​the indwelling intravenous needle, ensuring that the observation range fully covers the needle hole and surrounding skin.

[0050] Furthermore, the second fastener 41 employs a bayonet suitable for securing the positive pressure connector.

[0051] In practice, the connector of the indwelling intravenous catheter with the positive pressure connector is pressed and inserted into the bayonet of the positive pressure connector to fix the connector of the indwelling intravenous catheter.

[0052] Furthermore, the connector fixing part 4 is a long strip of fabric loop, 3cm long and 1cm wide.

[0053] In practical implementation, the dimensions of the connector fixing part 4 are set to 3 cm in length and 1 cm in width. This size has been optimized so that it can effectively fix the indwelling needle connector without taking up too much space, thus ensuring the practicality and compactness of the connector fixing part 4.

[0054] Cloth loops refer to buttons, straps, or buckles made of fabric used to fasten clothing in traditional Chinese garments.

[0055] Furthermore, the second fastener 41 is a Velcro fastener.

[0056] In practical implementation, the second fastener 41 is designed with Velcro, which allows the second fastener 41 to quickly fix the connector of the indwelling intravenous needle to the connector fixing part 4.

[0057] The second fastener 41 is a hook and loop fastener, with the hook side and the loop side of the fastener fixed to the inner and outer sides of both ends of the connector fixing part 4, respectively.

[0058] Furthermore, the fixing strap 1 is 15-25cm long and 9cm wide, and comes in three sizes: S, M, and L, which can be adapted to different limb sizes by means of the elasticity of the fabric.

[0059] In practice, the size of the fixation strap 1 is set to be 15 to 25 cm in length and 9 cm in width, and it is divided into three specifications: S, M and L. The elasticity of the fabric is used to adapt to different limb sizes and meet the needs of diverse patient groups such as children and adults.

[0060] A method for securing an indwelling intravenous catheter, using a catheter securing and protective strap, includes the following steps: S1. After completing the intravenous catheter insertion and covering with a transparent dressing, wrap the fixation strap 1 around the limb and align the observation window 2 with the transparent dressing. S2. Adjust the tightness of the fixing strap 1 and fix it to the limb using the first fixing member 3; S3. Fix the connector of the indwelling intravenous catheter to the connector fixing part 4; S4. During the fixed period, observe the condition of the puncture site directly through observation window 2 and perform nursing procedures.

[0061] Furthermore, the standard for adjusting the tightness of the fixation strap 1 is: after fixation, a finger can be inserted between the fixation strap 1 and the limb.

[0062] Anti-drop and displacement The elastic and breathable material of the fixation strap 1 generates a continuous contraction force when wrapped around the limb. This force is evenly applied to the indwelling needle and surrounding skin, forming a circumferential fixation that effectively restricts the displacement of the indwelling needle during limb movement.

[0063] Breathable and elastic fabric wraps around the limbs, forming a physical barrier to prevent external objects (such as clothing and bed sheets) from directly rubbing against the indwelling needle site, avoiding the risk of the transparent film curling, becoming contaminated, and the catheter dislodging.

[0064] The four pairs of indwelling needle connectors are secured in the connector fixing part, which reduces the tension on the connectors caused by movement and protects the catheter. Compared with ordinary bandages or dressings, it has stronger elasticity and adaptability. Even if the patient moves their limbs, the fixing strap can maintain the fixing force through elastic deformation, which greatly reduces the risk of dislodgement.

[0065] Real-time observation The location and size of the observation window 2 are precisely designed to correspond exactly to the transparent dressing area of ​​the indwelling intravenous needle.

[0066] The transparent dressing itself is transparent, and combined with the unobstructed design of the observation window 2, nursing staff can directly observe the skin color at the needle hole, the integrity of the dressing, and whether there is any liquid seepage through the observation window 2, which solves the contradiction in the existing technology that "it is impossible to observe when it is fixed, and it is necessary to unfix it when it is observed".

[0067] Multi-scenario adaptation function Size fit: The triple design of "elastic fabric + multiple length specifications + first fastener adjustment" meets the different limb sizes of children and adults.

[0068] Operational adaptation: The opening area fully exposes the puncture point of the indwelling needle and the infusion connector, allowing nurses to directly perform flushing and infusion operations without removing the protective cover, thus improving nursing efficiency.

[0069] Comfort and safety The elastic and breathable properties of the fixation strap 1 prevent excessive pressure on the limbs during fixation. The adjusted tightness ensures normal blood circulation in the limbs and avoids limb swelling or circulatory disorders caused by excessive fixation. The presence of observation window 2 reduces the frequency with which nursing staff need to untie the bandage, lowers the risk of the indwelling needle falling out due to frequent operation, and further ensures the safety of patients from an operational perspective. The breathable and elastic fabric reduces the probability of skin allergies due to its skin-friendly properties, while the breathable design reduces sweat buildup. The metal-free design of the first fastener avoids interference with medical imaging examinations, meeting the dual needs of patients for daily activities and medical treatment.

[0070] Indwelling intravenous catheter: An infusion device that can be left in a vein for several days for long-term infusion therapy. It needs to be reliably fixed to prevent the needle from falling out or shifting.

[0071] Fixation strap: Made of elastic and breathable medical fabric, it can fix the limb and indwelling needle through elastic contraction force and is suitable for different limb sizes.

[0072] Transparent dressing: A medical transparent film that covers the puncture site of an indwelling intravenous needle to protect the puncture site, prevent infection, and allow for visualization of the puncture site.

[0073] Observation window: A through-hole made in the elastic bandage, positioned corresponding to the transparent dressing, used to directly observe the skin and dressing condition at the needle puncture site.
