Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary device technology, specifically relating to an indwelling needle fixation device. Background Technology

[0002] The core components of an indwelling needle include a flexible catheter that can be left in a blood vessel and a stainless steel puncture guide needle core. When in use, the catheter and needle core are inserted into the blood vessel together. After the catheter is fully inserted into the blood vessel, the needle core is withdrawn, leaving only the flexible catheter in the blood vessel. The connector is fixed to the back of the patient's hand or the infusion site for infusion treatment.

[0003] Some patients, such as infants, or those with illnesses or physical conditions, have difficulty identifying their veins, making it challenging for medical staff to insert needles and causing continuous pain. If a patient needs intravenous infusions for several days, current technology generally uses indwelling needles to reduce the pain of venipuncture each time. With indwelling needles, only the inlet end needs to be connected to the infusion tubing each time, avoiding repeated punctures. However, since the indwelling needle is implanted in the patient's vein, it must be kept clean and prevent displacement during patient activity to avoid damage or injury. Therefore, the indwelling needle needs to be secured. Currently, a common method is to fix the connector to the back of the hand using a fixation plate and medical gauze to restrict hand movement. The biggest problem with this method is that medical staff cannot directly observe the indwelling needle, requiring repeated unwrapping of the bandages each time, which is inconvenient. Furthermore, fixation plates are often homemade straight boards (cardboard, wood, etc.), which are hard and can easily squeeze the indwelling needle during patient movement, making them inconvenient to use.

[0021] The extension tube of the transparent three-way connector passes through the adhesive tape 1 and is connected to the positive pressure connector of the indwelling needle drug delivery end. The positive pressure connector is placed on the top surface of the adhesive hook tape 4.

[0022] Then, the hook strap 4 is bent so that the Velcro end 5 on the left end of the hook strap 4 is attached to the Velcro end 6 on the right end, so as to fix the transparent tee and the positive pressure connector of the drug delivery end on the back of the patient's hand respectively. The Velcro end 6 is bent towards the Velcro end 5 to avoid the hook strap 4 from covering the dressing 2 and dressing core 3, which facilitates observation. In addition, the fixation method is changed so that the direction of the drug delivery bottle connected to the drug delivery end is parallel to the direction of the arm. When the patient moves, it is less likely to squeeze the indwelling needle and cause secondary injury to the patient.

[0023] The left half of the top surface of the adhesive hook 4 can also be detachably installed with a medical double-sided adhesive 8 that matches the contour of the adhesive hook 4. The left side of the medical double-sided adhesive 8 contacts the left side of the Velcro end 5. The right half of the top surface of the adhesive hook 4 is provided with an adhesive area 9 for the medical double-sided adhesive 8 to adhere. The contour of the medical double-sided adhesive 8 and the contour of the adhesive area 9 are symmetrical about the central axis of the mounting hole 7. In use, the medicine dispensing bottle of the medicine dispensing end is inserted above the adhesive area 9, the protective film on the surface of the medical double-sided adhesive 8 is peeled off, and when the adhesive hook 4 is folded in half, the medical double-sided adhesive 8 adheres to the adhesive area 9. The medical double-sided adhesive 8 wraps around the positive pressure connector of the medicine dispensing end. The positive pressure valve of the medicine dispensing end passes out from the front or right side of the closed adhesive hook 4. The medicine dispensing bottle with the end cap passes through the mounting hole 7 and out of the adhesive hook 4 for easy medicine dispensing.

[0024] An opening 10 is provided at the adhesive tape 1 that is horizontal to the front and back direction of the dressing core 3; the adhesive tape 1 on one side of the opening 10 is used to fix the needle holder of the indwelling needle to prevent the indwelling needle from shifting or rotating. At the same time, in order to conform to the irregular contour of the indwelling needle, the blocking plug of the indwelling needle is exposed to facilitate adjustment by medical staff.

[0025] The dressing core 3 is made of hydrocolloid, and the dressing 2 is made of a transparent polyurethane film. The dressing 2 is transparent and has breathable and waterproof functions. The dressing core 3 is semi-transparent. The design of the dressing 2 and the dressing core 3, as well as their material properties, can effectively increase the water absorption of the effective working area of ​​the indwelling needle fixation device, absorb more blood and exudate at the puncture site, keep the wound at the puncture point dry, and prevent phlebitis. The dressing 2 is also breathable and waterproof, and facilitates observation of changes at the puncture point. If redness, swelling, bleeding, or other conditions occur at the puncture point, they can be detected in time and communicated to medical staff.

[0026] The adhesive area 9 and the leftmost end of the mounting hole 7 are connected by a notch 11 that is open at both ends. Specifically, the notch 11 is cut out from the adhesive hook 4 at the leftmost end of the mounting hole. When the adhesive hook 4 is laid flat, the notch 11 is linear. When the adhesive hook 4 is folded, the notch 11 becomes three-dimensional, so that the front and rear edges of the adhesive hook 4 are slightly closer together and the notch opens, making it easier for the drug delivery bottle of the indwelling needle to pass through the mounting hole. After the folding is completed, the notch 11 returns to a linear shape, or it can be used with medical double-sided tape 8 to make the contact area between the medical double-sided tape 8 and the adhesive area 9 larger.
