Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a self-heating indwelling needle dressing for the prevention of phlebitis. Background Technology

[0002] Indwelling needle dressing is a sterile, transparent gel-like film used to fix indwelling needles. The product structure includes a film base strip: which serves as the base part of the dressing and plays a supporting and load-bearing role.

[0003] Adhesive layer: This layer is adhesive, allowing the dressing to adhere tightly to the skin, securing the indwelling needle, and preventing it from shifting or falling off. The adhesive layer's tackiness should not exceed 2.5mm to ensure a firm bond without being too sticky and causing skin damage.

[0004] Absorbent dressing (if applicable): Some indwelling needle dressings have absorbent dressings, whose non-swelling absorption capacity should be no less than 5.0 g / 100 cm². 2 It can absorb blood and fluid from the puncture site, keep the puncture site dry, and reduce the risk of infection.

[0005] Release paper: Protects the adhesive layer from contamination before application; remove before use.

[0006] When administering medication to prevent phlebitis, the low temperature of the medication and its prolonged injection into the blood vessel can lower the temperature of the skin around the injection site. To improve comfort during injection, a self-heating pack is often attached to the indwelling needle dressing. Currently, most self-heating packs are glued to the dressing and discarded after use. However, the self-heating pack continues to dissipate heat even when discarded, leading to a high temperature inside the trash can near the pack, posing a safety hazard. Furthermore, since most materials used in indwelling needle dressings are reusable, discarding them with the self-heating pack increases the difficulty of subsequent material reuse. Therefore, this application proposes a self-heating indwelling needle dressing for the prevention of phlebitis. Utility Model Content

[0029] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0030] Phlebitis, also known as thrombophlebitis, is an acute, non-suppurative inflammation caused by a blood clot blocking a blood vessel. This condition can occur in either superficial or deep veins. Superficial phlebitis typically presents with localized redness, swelling, heat, and pain. It is a self-limiting disease, usually treatable with symptomatic pain relief, anti-inflammatory drugs, and treatments that promote venous return.

[0031] Deep vein thrombosis (DVT) symptoms are usually less pronounced than those of superficial vein thrombosis (SVT), with greater swelling and often less noticeable local symptoms, but more pronounced systemic symptoms. Treatment involves the same symptomatic relief as for superficial vein thrombosis, but the most important aspect is anticoagulation therapy for deep vein thrombosis, primarily through intravenous medication.

[0032] Phlebitis can be prevented through regular sleep patterns, dietary adjustments, appropriate exercise, removal of triggering factors, and standardized medication use. It is also recommended to seek examination and treatment at a reputable hospital.

[0033] 1. Regular lifestyle: Phlebitis is a sterile inflammation of the veins. It is important to maintain good living habits, regular lifestyle, and avoid standing or sitting for long periods of time to prevent blood return obstruction.

[0034] 2. Dietary adjustments: The diet should be mainly light, with more fruits and vegetables such as cucumbers and kiwis, which can help promote metabolism and blood circulation, and also help prevent arteritis.

[0035] 3. Appropriate exercise: You can do appropriate aerobic exercise, such as yoga or jogging, which can accelerate blood circulation, avoid blood return obstruction, and also help prevent phlebitis.

[0036] 4. Use medication as prescribed: If poor blood circulation is caused by varicose veins in the lower limbs, you can take medications such as diosmin tablets and sodium aescinate tablets as prescribed by your doctor. You can also have preventive injections to prevent the occurrence of phlebitis.

[0037] like Figures 1 to 4 As shown, in order to fix the position of the needle during the injection of drugs for the prevention of phlebitis and prevent the needle from shifting during the injection process, this utility model provides a self-heating indwelling needle dressing for the prevention of phlebitis, including an indwelling needle dressing body 1, which can be referred to as... Figure 3 , Figure 4 The indwelling needle dressing body 1 includes a film 101, a transparent window 102, an adhesive application area 103, a release film 104, a self-heating pack 105, and a storage frame 106. Specifically, the transparent window 102 is located in the middle of the film 101. When the medication is injected, the injection needle is inserted into the blood vessel, and the film 101 is attached to the skin around the injection needle to attach the injection needle to the injection site. In order to facilitate the observation of the injection site, the transparent window 102 is set in the middle of the film 101 to facilitate the injection personnel and medical staff to observe the injection situation and to allow the injection personnel and medical staff to observe the swelling of the blood vessel in a timely manner.

[0038] More specifically, the adhesive application area 103 is located at one end of the film 101, and the shape of the adhesive application area 103 is the same as the shape of the film 101. Specifically, the side of the film 101 is offset inward by 0.5-1.2cm and together with the side of the film 101, they form the adhesive application area 103. This allows the adhesive application area 103 to be attached to the periphery of the transparent window 102 and fix the needle in place.

[0039] It should be noted that the release film 104 covers the adhesive application area 103. It is used to protect the adhesive application area 103, prevent the adhesive in the adhesive application area 103 from being contaminated, and ensure the adhesion of the adhesive application area 103. When using it, simply peel off the release film 104.

[0040] It should be mentioned that the self-heating pack 105 is located at the end of the film 101 away from the adhesive application area 103, and the self-heating pack 105 is located outside the transparent window 102. The self-heating pack 105 surrounds the transparent window 102, and one end of the self-heating pack 105 is provided with an opening corresponding to the area where the needle is connected to the syringe. The heating area of ​​the self-heating pack 105 is located around the transparent window 102, and will not directly heat the syringe and the liquid inside the syringe, thus avoiding the heated liquid from irritating the blood. At the same time, the opening can save some of the self-heating pack 105 and reduce the input of materials.

[0041] Specifically, the self-heating pack 105 is wrapped in medical non-woven fabric, and the bag is filled with iron powder, activated carbon, vermiculite, water, and salt. The activated carbon absorbs moisture from the air, and the iron powder reacts with the moisture in the air to produce ferric hydroxide and release heat. Activated carbon has thermal conductivity and can dissipate heat evenly. In this way, the self-heating pack 105 can dissipate heat to the injection area where the film 101 is attached, alleviating the low temperature in the injection area caused by the injection of medication.

[0042] More specifically, a storage frame 106 is provided at the film 101, and the self-heating pack 105 is stored in the storage frame 106. The self-heating pack 105 and the film 101 are detachably connected. One way of detachable connection is that a hook and loop fastener is provided between the self-heating pack 105 and the film 101. The hook and loop fastener includes a hook and loop pin surface 107 and a hook and loop loop surface 108. The hook and loop pin surface 107 is provided on the self-heating pack 105, and the hook and loop loop surface 108 is provided on the film 101. Another detachable connection method can be assembled using a snap-fit ​​structure. The self-heating pack 105 and the film 101 are detachably connected, which facilitates the separation of the self-heating pack 105. The self-heating pack 105 and the film 101 can be placed separately into different waste storage bins, avoiding the risk of the heat released by the self-heating pack 105 causing the temperature of flammable items inside the waste bin to become too high. The self-heating pack 105 and the film 101 and other recyclable materials are placed separately, which facilitates the subsequent processing of the two types of waste, namely the self-heating pack 105 and the film 101.

[0043] Since the self-heating pack 105 continuously transfers heat to the area where the film 101 is attached, and the film 101 is attached to the skin of the injection area where air circulation is relatively inconvenient, in order to avoid the problem of sweating on the underside of the film 101, which could cause the film 101 to loosen its adhesion to the skin and cause discomfort in the injection area, a ventilation window 109 is provided on the film 101. A breathable non-woven fabric is provided inside the ventilation window 109, and a window opening and closing film 110 is provided at the ventilation window 109. One end of the window opening and closing film 110 is connected to the film 101 with adhesive, and the other end can be opened and closed for easy operation of opening and closing the window opening and closing film 110.

[0044] It should be noted that the package also includes a packaging bag 2, which is used to store the indwelling needle dressing body 1. The packaging bag 2 is provided with a bag body 201, an easy-tear film 202 for easy removal of the indwelling needle dressing body 1, and a label 203. After tearing open the easy-tear film 202, the indwelling needle dressing body 1 can be taken out from the packaging bag 2. The label 203 is used to mark the production information of the indwelling needle dressing body 1.

[0045] In summary, the present invention provides a self-heating indwelling needle dressing for preventing phlebitis. When the medication for preventing phlebitis is injected, the injection needle is inserted into the blood vessel. The dressing 101 is attached to the skin around the injection needle by the adhesive at the adhesive application area 103, thus attaching the injection needle to the injection site. A transparent window 102 is provided in the middle of the dressing 101 to facilitate the injection personnel and medical staff to observe the injection situation and to allow them to promptly observe the swelling of the blood vessel.

[0046] A self-heating pack 105 is installed on the film 101. The self-heating pack 105 can heat the area around the transparent window 102, alleviating the problem of low temperature in the injection area caused by the injection of medicine, and improving the comfort of the injection personnel. The self-heating pack 105 and the film 101 are detachably connected, which facilitates the separation of the self-heating pack 105 and the film 101. The self-heating pack 105 and the film 101 can be placed separately into different waste storage bins, avoiding the risk of the heat released by the self-heating pack 105 causing the temperature of flammable materials inside the waste bin to become too high. It also facilitates the separation of the self-heating pack 105 and the film 101 and other recyclable materials, which is convenient for the subsequent classification and processing of the two types of waste.

[0047] The opening inside the self-heating pack 105 corresponds to the area where the needle tube is connected. The area heated by the self-heating pack 105 is located around the transparent window 102, and it will not directly heat the needle tube and the liquid inside the needle tube, thus avoiding the heated liquid from irritating the blood. At the same time, setting an opening can save some of the self-heating pack 105 and reduce the input of materials.

[0048] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
