Description

Technical Field

[0001] This utility model belongs to the field of fixation technology, specifically relating to a head infusion needle fixation device. Background Technology

[0002] Infants under two years old often have more flesh on their arms, making veins difficult to spot. Therefore, upper limb intravenous infusion is generally not used when intravenous treatment is needed. Furthermore, due to the active nature of infants, upper limb infusion carries the risk of needle dislodgement due to the child's arm movements. This is another reason why upper limb intravenous infusion is not currently used for children under two years old.

[0003] Children's scalps have abundant veins, and because the scalp is relatively thin, the veins are quite superficial and clearly visible, usually appearing as a light blue color. Furthermore, the blood vessel walls are relatively thin, making them easily bulge when compressed, thus making them readily visible. This makes it easier to insert a needle. In addition, needles inserted into the scalp are easier to secure and less likely to fall out, allowing for more freedom of movement for the child's limbs.

[0004] Currently, the main method for securing intravenous needles involves first attaching tape to the needle, then wrapping the tape around the child's head. During the needle insertion and fixation process, medical staff need to accurately locate the puncture site, perform the puncture, and then secure it with tape. For novice nurses, the child's struggles during the fixation process can cause deviations in the puncture site. Furthermore, the subsequent process of securing the needle with one hand while using the other to apply tape can easily cause the needle to shift, affecting the effectiveness of the intravenous infusion. Utility Model Content

[0005] This utility model discloses a head infusion needle fixation device, which aims to solve the technical problem in the prior art that the infusion effect may be affected by the deviation of the puncture position and the displacement of the infusion needle during fixation when performing puncture on children.

[0006] To solve the aforementioned technical problems, the present invention adopts the following technical solution:

[0007] A head-mounted infusion needle fixation device includes a first fixation strap fitted onto the head of a child. The first fixation strap is an elastic band. A window is provided on the first fixation strap, and a first fixation device for fixing the infusion needle is provided on the window. The first fixation device includes a positioning plate connected to the first fixation strap. The positioning plate is located on the side close to the child's head. The positioning plate is provided with a guide hole that mates with the body of the infusion needle and a receiving groove that mates with the wing of the infusion needle. A guide tube is connected to the positioning plate, and the guide tube communicates with the guide hole.

[0008] With this technical solution, the first fixing band is designed as an elastic band, making it suitable for children with any head circumference, thus increasing the device's practicality. A window is directly provided on the first fixing band, allowing for initial positioning of the puncture site on the child's head. The first fixing device on the window then guides and fixes the insertion point of the infusion needle, ensuring the guide tube is initially aligned with the final puncture site, improving accuracy. Simultaneously, the first fixing band works in conjunction with the child's head to compress and fix the positioning plate and guide tube, thus restricting the puncture location and further improving accuracy and stability of the infusion needle position after puncture.

[0009] This device improves the accuracy of puncture and fixation, ensuring the effectiveness of intravenous infusion for the child. Furthermore, because it avoids using tape to secure the device to the child's hair or other areas, it reduces the risk of injury when removing the tape due to hair sticking to it, thus improving the child's comfort.

[0010] The first fixing strap is connected to a positioning component, which includes a positioning frame fitted inside the window. The positioning frame is slidably connected to the guide tube, and the positioning plate is detachably connected to the first fixing strap.

[0011] With this technical solution, the guide tube and positioning frame are slidably connected, and the positioning plate and the first fixing strap are detachably connected. When the window is initially aligned with the area where the child needs to be punctured, fine adjustments can be made by the relative sliding of the guide tube and the positioning frame. The end of the guide tube inside the window is aligned with the puncture point to be punctured. Once the puncture point is determined, the positioning plate is connected to the first fixing strap to restrict the position of the guide tube. This connection method improves the practicality of the device.

[0012] The positioning frame is provided with a sliding groove, the guide tube is provided with a slider that cooperates with the sliding groove, the positioning plate is provided with a hook and loop fastener, and the first fixing band is provided with a hook and loop fastener that cooperates with the hook and loop fastener.

[0013] With this technical solution, the fit between the slide and the slider is more stable, and the connection between the hook and loop fasteners is more stable, enabling the device to quickly and stably adjust the position of the positioning plate and guide tube. This improves the work efficiency of medical staff and the stability of the device during use.

[0014] The first fixing strap is further provided with a second fixing device for fixing the guide tube. The second fixing device includes a connecting strap connected to the first fixing strap. The connecting strap is located on the side of the window away from the child's head. The connecting strap is connected to a fixing block. The fixing block is provided with a limiting groove that cooperates with the guide tube. The connecting strap is an elastic strap. A magnetic adhesive is provided on the side of the connecting strap away from the fixing block. A magnetic female adhesive is provided on the first fixing strap that cooperates with the magnetic adhesive.

[0015] After adopting this technical solution, once the infusion needle enters the vein in the child's head, the puncture site can first be protected with a sterile patch. After flipping the fixing block to disconnect the magnetic ferrule and the magnetic ferrule, the fixing block comes into contact with the guide tube. Through the connecting elasticity, the fixing block squeezes the guide tube, restricting the longitudinal position between the infusion needle and the scalp. This improves the fixation and positioning effect of the infusion needle while ensuring safety.

[0016] The positioning plate is also provided with a limiting device for limiting the position of the infusion tube. The limiting device includes a second fixing band connected to the positioning plate. The other end of the second fixing band is connected to the first fixing band. The second fixing band is perpendicular to the first fixing band. A silicone ring is provided on the second fixing band. The silicone ring has an opening. After the infusion tube passes through the opening, it can be placed in the fixing groove formed by the silicone ring.

[0017] After the infusion needle is secured, the infusion tubing can be inserted into the fixing groove along the direction of the silicone ring to fix the tubing above the child's head. This prevents the risk of needle dislodgement or changes in the puncture site caused by the child grasping the tubing, thus improving the safety of the child during infusion.

[0018] The silicone ring is provided with a retaining ring that mates with the infusion tube.

[0019] By adopting this technical solution, the position of the infusion tube from the silicone ring can be restricted by the retaining ring, so that the point of disconnection between the infusion tube and the child is at the top of the child's head. The infusion tube is suspended above the child's head, preventing the risk of needle dislodgement or displacement caused by the child grabbing the infusion tube, and further improving the safety of the child during infusion.

[0020] The silicone ring includes a connecting part connected to the positioning plate and a limiting part that limits the movement of the infusion needle wing. The limiting part covers the receiving groove, and when the infusion needle wing enters the receiving groove, it is limited by the limiting part.

[0021] With this technical solution, the limiting part of the silicone ring cooperates with the receiving groove. After the infusion needle wing enters the receiving groove, the wing can abut against the silicone ring, so that the wing remains in the receiving groove until the infusion is finished. This restricts the position of the infusion needle relative to the scalp surface, making the infusion needle more stable during infusion and improving the infusion effect for the child.

[0022] The first fixing strap has an anti-slip cushioning pad on the side closest to the child's head.

[0023] By adopting this technical solution, the anti-slip cushioning pad can improve the comfort of children when using this device.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0025] (1) The use of a first fixation strap, window, positioning plate, guide tube, etc. improves the accuracy of the puncture position and the accuracy of the fixation position. It has an auxiliary confirmation effect for novice nurses and can also ensure the infusion effect and comfort of children.

[0026] (2) The first-strapped fixation strap is used to fix the child's head. The fixation method is simple and does not require adhesive tape. This reduces the discomfort caused by the hair sticking and tearing during subsequent needle removal, as well as the scalp allergy caused by adhesive tape in some children. At the same time, it can be used for children of any head size, making it highly practical.

[0027] (3) Using fixing blocks, connecting straps, etc. can further improve the fixation effect on the infusion needle and ensure the infusion effect.

[0028] (4) The infusion tube is fixed simultaneously with a second fixing strap, silicone ring, etc., to avoid the needle displacement caused by children grabbing it, which has a high safety factor.

[0029] (5) Using anti-slip cushioning pads can increase the comfort of children when using this device. Attached Figure Description

[0037] The following is combined with Figures 1-2 This utility model will be described in detail.

[0038] Example 1

[0039] A head-mounted infusion needle fixation device, such as Figure 1 and Figure 2As shown, the device includes a first fixing strap 1 that is fitted onto the child's head. The first fixing strap 1 is an elastic strap. The first fixing strap 1 has a window 102. The window 102 has a first fixing device 2 for fixing the infusion needle 4. The first fixing device 2 includes a positioning plate 201 connected to the first fixing strap 1. The positioning plate 201 is located on the side close to the child's head. The positioning plate 201 has a guide hole that mates with the needle body of the infusion needle 4 and a receiving groove 202 that mates with the needle wings of the infusion needle 4. The positioning plate 201 is connected to a guide tube 203, which communicates with the guide hole.

[0040] In this embodiment, the window 102 is integrally formed with the first fixing strap 1, and the size of the window 102 is 5*3cm.

[0041] In this embodiment, a fixing line is sewn around the window 102 to fix the window 102 and make the window 102 more stable.

[0042] In this embodiment, the length of the guide tube 203 and the guide hole is less than the length of the infusion needle 4 by 10mm, and the length of the guide tube 203 placed in the window 102 is 1cm.

[0043] In this embodiment, the positioning plate 201 and the guide tube 203 are both made of transparent silicone material, so the condition of the infusion needle can be clearly observed during puncture.

[0044] In this embodiment, the positioning plate 201 and the guide tube 203 are both made of silicone. Silicone is soft and skin-friendly, and can fit well with the skin. The guide hole and the guide tube 203 are oriented at an angle along the top of the child's head and close to the puncture point on the child's head.

[0045] The first fixing band 1 is an elastic band, which can be used with children of any head circumference, increasing the practicality of the device. A window 102 is directly set on the first fixing band 1. Through the window 102, the position to be punctured on the child's head can be initially located. Then, the first fixing device 2 set on the window 102 directly guides and fixes the insertion position of the infusion needle 4, so that the guide tube 203 is on the same straight line as the final puncture position, improving the accuracy of the puncture position.

[0046] Simultaneously, the first fixing band 1 works in conjunction with the child's head to compress and fix the positioning plate 201 and guide tube 203, thereby restricting the puncture position and improving the accuracy of the puncture location and the stability of the fixation of the infusion needle 4 after puncture. Because this device improves the accuracy of the puncture and fixation positions, it ensures the effectiveness of the infusion for the child. Furthermore, since this device does not use tape to fix the child to their hair or other areas, it reduces the risk of injury to the child when removing the tape due to hair sticking to it, thus improving the child's comfort.

[0047] In this embodiment, the first fixing strap 1 is connected to a positioning component, the positioning component includes a positioning frame 101 sleeved inside the window 102, the positioning frame 101 is slidably connected to the guide tube 203, and the positioning plate 201 is detachably connected to the first fixing strap 1.

[0048] In this embodiment, the positioning frame 101 is a frame structure made of silicone material. The positioning frame 101 includes mounting plates that can be snapped onto the two walls of the window 102. The two opposite mounting plates form a mounting groove that can accommodate the window 102. The positioning frame 101 is bonded to the window 102. After applying adhesive to the mounting groove, the window 102 is bonded to the mounting groove. The bonding makes the connection between the two relatively flat and more secure during use.

[0049] The guide tube 203 and the positioning frame 101 are slidably connected, and the positioning plate 201 is detachably connected to the first fixing strap 1. When the window 102 is initially aligned with the site where the child needs to be punctured, fine adjustments can be made by the relative sliding of the guide tube 203 and the positioning frame 101. The port of the guide tube 203 inside the window 102 is aligned with the puncture point to be punctured. Once the puncture point is determined, the positioning plate 201 is connected to the first fixing strap 1 to restrict the position of the guide tube 203. This connection method improves the practicality of the device.

[0050] In this embodiment, the positioning frame 101 is provided with a sliding groove 103, the guide tube 203 is provided with a slider 204 that cooperates with the sliding groove 103, the positioning plate 201 is provided with a hook and loop fastener surface, and the first fixing band 1 is provided with a hook and loop fastener surface that cooperates with the hook and loop fastener surface.

[0051] In this embodiment, the slide groove 103 is disposed on the edge of the positioning frame 101 near the positioning plate 201, such as... Figure 2 As shown.

[0052] In this embodiment, the slide 103 and the positioning frame 101 are integrally formed.

[0053] In this embodiment, the guide tube 203 and the infusion needle 4 are fixed by an interference fit.

[0054] In this embodiment, the slider 204 is also made of silicone material and is bonded to the guide tube 203.

[0055] In this embodiment, the hook and loop fastener is attached to the positioning plate 201, and the hook and loop loose fastener is sewn to the first fixing strap 1. The length of the hook and loop loose fastener is equal to the length of the window 102, and the width is 1cm. Because the positioning plate 201 acts as an isolation between the hook and loop fastener and the child's head, the hook and loop fastener will not come into contact with the child's head or stick to the child's hair, which can increase the convenience for the child to use this device.

[0056] The sliding groove 103 and the slider 204 have a relatively stable fit, and the connection between the hook and loop fastener surfaces is also relatively stable, enabling the device to quickly and stably adjust the position of the positioning plate 201 and the guide tube 203. This improves the work efficiency of medical staff and the stability of the device during use.

[0057] In this embodiment, the positioning plate 201 is also provided with a limiting device for limiting the position of the infusion tube. The limiting device includes a second fixing band connected to the positioning plate 201. The other end of the second fixing band is connected to the first fixing band 1. The second fixing band is perpendicular to the first fixing band 1. A silicone ring band 5 is provided on the second fixing band. The silicone ring band 5 is provided with an opening. After the infusion tube passes through the opening, it can be placed in the fixing groove formed by the silicone ring band 5.

[0058] In this embodiment, the second fixing strap is an elastic strap. One end of the second fixing strap is positioned where the positioning plate 201 contacts the child. After the second fixing strap is attached to the silicone ring 5, the silicone ring 5 is then attached to the positioning plate 201. Figure 2 As shown, the other end is sewn to the first fixing strap 1.

[0059] In this embodiment, the silicone ring 5 is bonded to the second fixing band, and the arc length of the opening is 0.6 mm.

[0060] After the infusion needle 4 is secured, the infusion tubing can be inserted into the fixing groove along the direction of the silicone ring 5 to fix the infusion tubing above the child's head. This prevents the risk of needle dislodgement or change of puncture position caused by the child grasping the infusion tubing, thus improving the safety of the child during infusion.

[0061] In this embodiment, the silicone ring 5 is provided with a retaining ring 501 that cooperates with the infusion tube.

[0062] In this embodiment, a rubber pad is adhered inside the retaining ring 501, the arc length of the notch of the retaining ring 501 is 0.6mm, and the silicone ring band 5 is provided with a retaining ring 501 mounting hole that mates with the retaining ring 501.

[0063] The retaining ring 501 restricts the position of the infusion tube from exiting the silicone ring 5, ensuring that the infusion tube disconnects from the child at the top of the child's head. This suspends the infusion tube above the child's head, preventing risks such as needle dislodgement or displacement caused by the child grasping the infusion tube, and further improving the child's safety during infusion.

[0064] In this embodiment, as Figure 2 As shown, the silicone ring 5 includes a connecting part connected to the positioning plate 201 and a limiting part for limiting the infusion needle wing. The limiting part covers the receiving groove 202. When the infusion needle 4 wing enters the receiving groove 202, it is limited by the limiting part.

[0065] In this embodiment, the connecting part is a connecting short strip connected to the end of the silicone ring 5. After the connecting short strip is bonded and fixed together with the silicone ring 5 and the second fixing strip, the connecting short strip is bonded to the positioning plate 201.

[0066] In this embodiment, the limiting part of the silicone ring 5 is the part that contacts the positioning plate 201. This part covers half the width of the receiving groove 202. After the needle wing of the infusion needle 4 enters the receiving groove 202, the needle wing can abut against the silicone ring 5, so that the needle wing stays in the receiving groove 202 until the infusion is finished. This restricts the position of the infusion needle 4 relative to the scalp surface, making the infusion needle 4 more stable during infusion and improving the infusion effect for the child.

[0067] In this embodiment, the first fixing strap 1 is provided with an anti-slip cushioning pad on the side near the child's head.

[0068] In this embodiment, the anti-slip cushioning pad comprises a rubber pad with anti-slip texture. The anti-slip cushioning pad improves the comfort of children using this device.

[0069] The specific method of using this utility model is as follows:

[0070] Reference Figures 1-2 When using this device, first attach the first fixing strap 1 to the child's head and align the area to be punctured with the window 102. Then slide the guide tube 203 and align the guide tube 203 with the area to be punctured. Finally, connect the Velcro piercing side of the positioning plate 201 with the Velcro rough side of the first fixing strap 1.

[0071] Then, medical staff disinfect the area within window 102. After disinfection, following the direction of the guide hole and guide tube 203 on the positioning plate 201, the infusion needle 4 is inserted into the child's head, ensuring the needle wings of the infusion needle 4 are in the receiving groove 202. A sterile dressing is then applied to the needle tip. The infusion needle is then compressed and restricted by the sterile dressing, guide tube 203, first fixing band 1, and the shape and volume of the child's head. (To improve the infusion effect, tape can be attached to the sterile dressing and then connected to the first fixing band 1. This restricts the infusion needle 4 to the puncture point on the child's head under the compression of the guide tube 203, tape, and first fixing band. Attaching the tape near window 102 saves on tape usage and prevents it from getting stuck to the child's hair, increasing the child's comfort when using the device.)

[0072] After the IV needle 4 is secured, directly insert the IV tubing at the tail of the needle wing into the silicone ring 5, ensuring the needle wing is contained by the silicone ring 5. Pass one end of the IV tubing through the securing groove, then connect the IV tubing to the retaining ring 501. Once everything is secured, the child will be more stable when receiving IV fluids at the head.

[0073] Example 2

[0074] This embodiment is basically the same as Embodiment 1, except that: in this embodiment, as shown in the example... Figure 1 and Figure 2 As shown, the first fixing strap 1 is also provided with a second fixing device 3 for fixing the guide tube 203. The second fixing device 3 includes a connecting strap 302 connected to the first fixing strap 1. The connecting strap 302 is located on the side of the window 102 away from the child's head. The connecting strap 302 is connected to a fixing block 301. The fixing block 301 is provided with a limiting groove that cooperates with the guide tube 203. The connecting strap 302 is an elastic strap. A magnetic adhesive sticker 303 is provided on the side of the connecting strap 302 away from the fixing block 301. A magnetic female sticker that cooperates with the magnetic adhesive sticker 303 is provided on the first fixing strap 1.

[0075] In this embodiment, the magnetic fastener and magnetic female fastener are provided so that when the fixing block 301 is not in contact with the guide tube 203, the fixing block 301 will not be directly driven to contact the guide tube 203 under the elastic force of the connecting strap 302. In other embodiments, as long as this effect can be achieved, other methods can be used, such as using Velcro to stick together.

[0076] In this embodiment, the fixing block 301 is made of transparent silicone material. Silicone is readily available, has a certain degree of elasticity, and can fit well with the guide tube 203, while also reducing costs.

[0077] In this embodiment, the connecting straps 302 are disposed at both ends of the window 102 and sewn together with the first fixing strap 1.

[0078] In this embodiment, the size of the fixing block 301 matches the size of the window 102.

[0079] In this embodiment, the magnetic clasp 303 is bonded to the connecting strip 302, and the magnetic clasp is bonded to the first fixing strip 1.

[0080] The setting of the fixing block 301 can initially determine the position of the puncture point with the window 102. After adjusting the guide tube 203, the position of the puncture point can be made more accurate. After the infusion needle 4 enters the vein in the child's head, the puncture point can be protected by a sterile patch. After flipping the fixing block 301 to disconnect the magnetic suction patch 303 and the magnetic suction mother patch, the fixing block 301 contacts the guide tube 203. Through the connecting elasticity, the fixing block 301 squeezes the guide tube 203, which restricts the longitudinal position between the infusion needle 4 and the scalp. Thus, while ensuring safety, the fixing and limiting effect of the infusion needle 4 is improved.

[0081] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
