Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and more specifically, to a medical indwelling needle patch. Background Art

[0002] In order to replace the previous adhesive tape, reduce the itching and allergies of the skin at the adhesive site, and improve the convenience of use for nurses, people often use indwelling needle patches to fix infusion needles and infusion catheters. Indwelling needle patches are composed of medical non-woven fabrics, medical pressure-sensitive adhesives, wood cotton, and release paper.

[0003] Existing medical indwelling needle patches, such as the medical indwelling needle patch disclosed in Chinese patent number CN213131309U, can reliably fix the indwelling needle on the skin of the indwelling part. The window on the patch body can easily observe the needle hole made by the indwelling needle on the skin. The film layer covers the hard part adjacent to the needle head of the indwelling needle. When the medical staff pulls out the indwelling needle, the film layer has a small pulling buoyancy on the indwelling needle, and the transparent layer and the film layer covering the indwelling needle also have a bacteria-isolating effect.

[0004] However, under the effect of the patch, the base of the indwelling needle is closely attached to the puncture point, which will lead to poor liquid dripping and increase the occurrence of complications of the intravenous indwelling needle. In addition, the fixation of the peripheral intravenous indwelling needle catheter does not conform to the high-lift platform method, which is prone to accidental extubation. At the same time, the patch is closely attached to the skin, which makes it difficult and time-consuming to remove, increasing the pain for the patient. In view of this, we propose a medical indwelling needle patch. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] The purpose of the present application is to provide a medical indwelling needle patch to solve the problems raised in the above background technology.

[0023] refer to Figure 1-3 , a technical solution proposed.

[0024] like Figure 1 As shown, the lower layer of the dressing body 1 is bonded with an anti-sticking isolation sheet 2, and the upper layer of the dressing body 1 is bonded with an anti-sticking film 14. The side of the anti-sticking film 14 is fixedly connected with an opening strip 15, and the height of the opening strip 15 is slightly higher than the position of the anti-sticking film 14. The medical staff can simply and quickly pull the opening strip 15 to remove the anti-sticking film 14 from the top of the dressing body 1. After the anti-sticking isolation sheet 2 at the bottom end of the dressing body 1 is removed, the medical staff can accurately observe the position of the anti-sticking isolation sheet 2 through the transparent dressing body 1. After the dressing body 1 is pasted and placed on the top of the indwelling needle 3 in a tension-free state, the protruding part of the catheter connector of the indwelling needle 3 under the dressing body 1 is gently pinched to shape it. After shaping, it is smoothed outward in parallel with the index finger to make the dressing body 1 fully contact and bond with the connector and the skin to avoid bubbles and gaps.

[0025] like Figure 2 As shown, after the anti-adhesive film 14 is peeled off, the dressing body 1 and the side adhesive layer 11 are exposed. The side adhesive layer 11 is fixedly arranged around the dressing body 1. The side adhesive layer 11 is made of non-woven fabric, which is more comfortable for patients to touch. It has a certain water absorption property. When the infusion personnel sweat at the infusion position, the sweat can be absorbed by the side adhesive layer 11, so as to prevent the dressing body 1 from getting damp and reduce the fixing effect of the dressing body 1 on the catheter.

[0026] When removing the patch body 1 of the existing device, the operator needs to first gently lift up a corner of the patch body 1, pinch the corner with the thumb and index finger, and gently pull it to the same side to make it slowly separate from the skin at an angle of 0 degrees, and then tear off one side from top to bottom. The medical staff needs to first lift up the patch body 1 that is tightly attached to the patient's skin. When facing the elderly or patients with skin diseases, this operation is difficult and time-consuming, and it is more likely to increase the pain of the patients. In the present application, the thickness of the side adhesive layer 11 is greater than the thickness of the patch body 1, and the patch body 1 can be directly separated by tearing off the side adhesive layer 11, which reduces the time of removal, reduces the pain of the patients, and reduces the difficulty of operation for medical staff;

[0027] like Figure 2 and Figure 3As shown, two frame protection layers 12 are bonded to the two sides of the side adhesive layer 11, and a tear line is set in the middle of the frame protection layer 12. When the frame protection layer 12 is torn, it appears as Figure 3 In the state of the opening protection strip 121 shown, the medical staff can tear the frame protection layer 12 to make it appear as the opening protection strip 121. The strength and durability of the non-woven fabric material of the side adhesive layer 11 are poor, and the fibers are arranged in a certain direction, which is easy to crack from a right angle. Therefore, the side adhesive layer 11 will also crack to a certain size as the frame protection layer 12 is torn. The torn opening is convenient for limiting the catheter of the indwelling needle 3. When the frame protection layer 12 is not torn, it can be removed from the top of the side adhesive layer 11. At this time, the frame protection layer 12 appears as shown. Figure 3 The support and protection strip 122 is in the state shown, and one end of the support and protection strip 122 is an adhesive layer. Medical staff can stick the support and protection strip 122 to the position below the opening protection strip 121. The two interact with each other to limit the catheter and at the same time, the catheter is lifted to avoid the base of the indwelling needle 3 being closely attached to the puncture point, resulting in poor liquid dripping. The staff is also required to move the catheter, which increases the pain of the medical staff. The indwelling needle 3 catheter is lifted to comply with the high-lifting platform method required for infusion, thereby reducing accidental extubation.

[0028] like Figure 2 As shown, protective sheets 13 are provided at the other two sides of the dressing body 1. The protective sheets 13 and the side edges of the side adhesive layer 11 can be set to a fixed connection state. The protective sheets 13 are retractable clips. After the dressing body 1 is attached, the medical staff can wrap the protective sheets 13 on both sides around the patient's wrist and engage them with each other to achieve the side limit fixation of the dressing body 1 and reduce the occurrence of curling. When the indwelling needle 3 needs to be removed, the protective sheets 13 on both sides can also be directly pulled to achieve the removal of the dressing body 1.

[0029] The protective sheet 13 and the side of the side adhesive layer 11 can also be set to a pasted state. The protective sheet 13 is made of anti-sticking material. After the patch body 1 is attached, the side of the side adhesive layer 11 is pressed by pressing and removing the protective sheet 13, so that the side of the side adhesive layer 11 is more in line with the patient's skin condition. The protective sheet 13 made of anti-sticking material cannot fit tightly to the patient's skin. Long-term infusion of the protective sheet 13 will cause skin discomfort to the patient.

[0030] Although examples of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
