Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a device for fixing and preventing displacement of pediatric indwelling intravenous needles. Background Technology

[0002] Indwelling intravenous catheters are an important treatment method in pediatric clinical practice. They reduce the pain caused by repeated intravenous punctures in children, protect blood vessels, cause minimal irritation to blood vessels, and facilitate clinical medication administration. Since the indwelling catheter is always inserted into the blood vessel, it is protected and fixed to the skin surface with tape when the child does not need to receive medication.

[0003] Traditionally, when securing an indwelling needle, tape is used to wrap it. However, because children's blood vessels are smaller and they are naturally more active, the needle can move within the blood vessel during their movements, potentially puncturing it and causing significant damage to the skin and blood vessels, increasing the pain of the puncture. Current technology involves having children wear special gloves with a pre-drilled opening. The indwelling needle is inserted through this opening into the child's blood vessel, and then secured to the glove with tape. However, in practice, children often feel uncomfortable wearing gloves and frequently fidget with them, requiring constant monitoring by family members, which is time-consuming. Furthermore, the glove completely covers the needle, making it impossible to see if it shifts, causing significant pain for the child and reducing the device's practicality. Utility Model Content

[0004] The purpose of this invention is to provide a device for fixing and preventing displacement of intravenous catheters in children. This device helps to solve the problem of children frequently scratching and manipulating the catheter due to discomfort from wearing gloves, reduces the energy expenditure of family members, and helps to observe the condition of the catheter.

[0018] To make the above-mentioned features and advantages of this utility model more easily understood, specific embodiments are described below in conjunction with the accompanying drawings, but this utility model is not limited thereto.

[0019] refer to Figures 1 to 5 A device for fixing and preventing displacement of an indwelling intravenous catheter in children includes an adhesive tape 1 for adhering to the skin surface of a child, serving to fix and support it. A pre-drilled groove 3 is formed at the center of the top of the adhesive tape 1, providing space for a needle 5. A sponge pad 4 is fixed to the center of the top of the adhesive tape 1, cushioning and protecting the area where the needle 5 contacts the skin, reducing irritation. The needle 5 for intravenous infusion is positioned at the top of the sponge pad 4, and a breathable patch 6 is attached to the top of the needle 5, with its front and rear ends adhering to the adhesive tape 1. The breathable patch 6 covers and fixes the needle 5 while maintaining ventilation. Multiple ventilation holes 7 are formed on the adhesive tape 1 to promote skin ventilation and reduce stuffiness and discomfort. An adjustment mechanism 2 is also provided at the top of the adhesive tape 1 to protect the needle 5 and ensure needle stability.

[0020] In this embodiment, the adjustment mechanism 2 includes a protective cover 202 for further protection of the needle 5, preventing external interference. The protective cover 202 is adhered and fixed to the top of the tape 1 to ensure a secure installation. Specifically, double-sided adhesive tape 201 is fixedly connected to both the front and rear sides of the top of the tape 1. The protective cover 202 is adhered to two pieces of double-sided adhesive tape 201 to initially fix the protective cover 202 onto the tape 1, ensuring the stability of the protective cover 202's position.

[0021] In this embodiment, to ensure that the protective cover 202 can be securely connected to the tape during reuse, a buckle 203 is fixedly connected to the top of the protective cover 202, and a locking block 204 is engaged at the rear of the buckle 203. An adjustable strap 207 with an adjustable working length is fixed between the front end of the buckle 203 and the rear end of the locking block 204. By cooperating with the adjustable strap 207, the protective cover 202 forms a closed structure, enhancing the protection of the needle 5.

[0022] Specifically, a clamping frame 205 is fixedly connected to the outer wall of the front end of the buckle 203. Insert rods 206 are provided on both the left and right sides of the inside of the clamping frame 205. The end of the clamping frame 205 that is away from the locking block 204 is fixedly connected to both ends of the adjusting band 207. The adjusting band 207 has multiple pairs of insertion holes 208 along its length for engaging with the two insertion rods 206. The clamping frame 205 and the insertion rods 206, along with the insertion holes 208, are used to adjust the length of the adjusting band 207 and prevent loosening. By selecting different positions of the insertion holes 208, the degree of pressure of the protective cover 202 on the needle 5 can be adjusted to meet different needs.

[0023] In this embodiment, an information panel 11 is provided on the top left side of the protective cover 202. The information panel 11 records important information related to the indwelling needle, such as the needle model, usage time, and responsible medical staff, facilitating viewing and management by medical personnel.

[0024] In this embodiment, each screw 12 has a slotted or Phillips head slot 13 on its top; specifically, a Phillips head slot can be used to facilitate installation and removal. The surfaces of the screws 12 are all smoothed to reduce friction with other objects and make the installation process smoother.

[0025] In this embodiment, an observation port 14 is provided on the top right side of the protective cover 202, and a transparent plate 15 is fixedly connected to the inner wall of the observation port 14. Through the observation port 14, the condition of the indwelling needle can be directly observed without opening the protective cover 202. The transparent plate 15 can both ensure observation and provide a certain degree of protection to prevent external contaminants from entering.

[0026] In this embodiment, a soft pad 16 is fixedly connected to the outer wall of the adjustment strap 207, and the surface of the soft pad 16 is smoothed. The soft pad 16 increases the comfort of the adjustment strap 207 when in contact with the skin, reducing pressure and friction on the skin.

[0027] In this embodiment, a double-sided adhesive tape 8 is fixedly connected to the top right side of the tape 1. The double-sided adhesive tape 8 is U-shaped with its port facing the protection direction. A protective cover 9 located on the right side of the protective cover 202 is fixedly connected to the top of the double-sided adhesive tape 8, and the needle 5 is protected by the protective cover 9. A groove 10 is provided at the bottom of the protective cover 9. The groove 10 is used to accommodate and fit the needle 5 and provide a protective space for the needle 5, preventing the protective cover 9 from pressing on the needle 5. The surface of the protective cover 9 is smoothed to reduce friction and facilitate cleaning.

[0028] In this embodiment, the right end of the protective cover 202 is also provided with a notch 209 so as to mate with the groove and avoid the needle tube.

[0029] Working principle: Before using the device, first, determine the position where the indwelling needle will be inserted into the blood vessel, and attach the tape 1 to the corresponding position; then, insert the needle 5 into the blood vessel through the pre-drilled groove 3, with the tail of the needle 5 placed on the sponge pad 4 at the top center of the tape 1. The sponge pad 4 acts as a buffer and protector, reducing the irritation of the needle 5 to the skin; the breathable patch 6 covers the top of the needle 5, with the front and rear ends of the breathable patch 6 adhering to the tape 1, providing initial fixation and protection for the needle 5, thereby securing the indwelling needle; the multiple vents 7 on the tape 1 help the skin breathe, reducing stuffiness and discomfort.

[0030] Next, the protective cover 202 is attached to the tape 1 with double-sided adhesive 201. Then, the buckle 203 is engaged with the locking block 204 to form a closed structure, protecting the needle 5. The clamping frame 205 and the insertion rod 206 are used to enhance the connection stability between the buckle 203 and the locking block 204. By selecting to engage the insertion rod 206 with the insertion hole 208 at different positions, the length of the adjusting band 207 is adjusted to change the degree of pressure of the protective cover 202 on the needle 5, so as to adapt to different needs and achieve better fixation and protection.

[0031] Finally, attach the double-sided tape 8 to the right side of the protective cover 202, and then attach the protective cover 8 onto the double-sided tape 8.
