[0001] This utility model relates to therapeutic devices, and more particularly to a portable integrated cold compress and medicated compress device. Background Technology
[0002] Phlebitis and drug extravasation are frequent challenges in clinical nursing, long troubling healthcare professionals and patients. Areas requiring indwelling catheter insertion are particularly sensitive and vulnerable due to their unique anatomy—small, superficial blood vessels surrounded by relatively fragile tissues—to mechanical stimulation (such as repeated punctures or catheter friction) or direct drug stimulation. This sensitivity not only increases the risk of phlebitis but also easily leads to drug extravasation, causing local swelling, pain, inflammation, and even more serious tissue damage, severely impacting the patient's treatment experience and recovery process.
[0003] A search revealed that CN218889923U discloses a disposable traditional Chinese medicine hot or cold compress pack, specifically comprising a glove body, an outer layer, an insulating layer, an inner layer, and a traditional Chinese medicine liquid pack. The glove body has a three-layer structure: the outer layer, which is furthest from the skin, is a heating or cooling layer; the inner layer, which is in contact with the skin, contains the traditional Chinese medicine liquid pack; and the insulating layer is located between the inner and outer layers. However, this prior art is only suitable for the hands, and the replacement of cooling dressings and medications is inconvenient.
[0004] Therefore, designing an integrated cold compress and medication dressing device with wide applicability and convenient replacement of cooling dressings and medications is a technical problem that needs to be solved. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present utility model.
[0029] This invention provides a portable, precise, and sustainable treatment solution for hand phlebitis and drug extravasation by combining cold compress physical therapy and drug-assisted treatment.
[0030] Cold compress therapy can constrict blood vessels due to low temperature, inhibit inflammatory response, and has an analgesic effect.
[0031] Drug-assisted therapy includes:
[0032] 1. Magnesium sulfate wet compress: It can penetrate through the skin to reduce inflammation and swelling, and is especially suitable for local tissue damage caused by drug extravasation.
[0033] 2. Four-layer application of traditional Chinese medicine patches: The ingredients of traditional Chinese medicine such as Ruyi Golden Powder can penetrate through the four layers of the cold compress patch to enhance the anti-inflammatory effect.
[0034] Example 1
[0035] This embodiment provides a portable integrated cold compress and medicated dressing device, which is fixed on the patient's skin and includes a cold compress layer 1, a cold source 2, a medicated auxiliary layer 3, a medicated patch 4, and a limiting mechanism 5.
[0036] like Figure 1 As shown, the cold compress layer 1 has a honeycomb structure and is made of flexible material (such as silicone or medical-grade soft TPU). It conforms to the curved surface of the hand through elastic deformation. The cold compress layer 1 has an insertion port 10 on one side or top, and the cold source 2 is placed inside the cold compress layer 1 through the insertion port 10.
[0037] Cold source 2 can be a gel water bag or ice pack, which are easy to replace.
[0038] like Figure 2 As shown, the drug-assisted layer 3 has a mesh structure, with one side in contact with the patient's skin and the other side in contact with the cold compress layer 1. The drug-assisted layer 3 has a medicated patch slot 30, and the medicated patch 4 is placed in the medicated patch slot 30. The medicated patch slot 30 has an adhesive backing or a clip, and the medicated patch 4 is pasted on the adhesive backing or fixed on the clip.
[0039] The drug-aid layer 3 includes a first sub-layer and a second sub-layer. The first sub-layer is close to the skin and is a non-woven adhesive tape or cotton pad to improve comfort and prevent skin damage. The second sub-layer is close to the patch 4 and is a permeable mesh.
[0040] The insertion port 10 or the patch slot 30 can be sealed with a zipper or Velcro.
[0041] The limiting mechanism 5 includes adjustable straps 50 and fixing buckles 51. The adjustable straps 50 are in two sets, with two straps in each set, and are fixed on both sides of the cold compress layer 1 respectively. The fixing buckles 51 are in two sets, with two straps in each set, and are installed at the ends of the two sets of adjustable straps 50 respectively. The two sets of fixing buckles 51 are interlocked and fixed on the patient's limb to prevent the device from shifting as a whole.
[0042] Example 2
[0043] This embodiment provides a portable integrated cold compress and medicated dressing device, which is fixed to the patient's wrist and includes a cold compress layer 1, a cold source 2, a medicated auxiliary layer 3, a medicated patch 4, and a limiting mechanism 5.
[0044] like Figure 3As shown, the cold compress layer 1 is divided into two pieces. One piece is located on the back of the hand, and the side near the fingers has an arc shape that corresponds to the shape of the fingers, which fits the hand structure better. The other piece is located on the forearm. The two pieces are connected by a soft connecting strap 11, and the connection point is the wrist position. The cold compress layer 1 has an insertion port 10 on one side or top, and the cold source 2 is placed in the cold compress layer 1 through the insertion port 10.
[0045] This embodiment is used for jointed areas such as the wrist, where the hand is frequently bent during use. If the cooling layer 1 is a single flexible structure, although it can conform to the static shape of the hand, it may cause local wrinkles or displacement due to insufficient material extensibility during dynamic activities, affecting the uniformity of the cooling application; repeated bending of the material can easily lead to fatigue and damage; and the pressure at the joints increases (such as when clenching a fist, the skin on the back of the hand is stretched, and the single cooling layer 1 may restrict movement). Therefore, a segmented structure is adopted, which is more flexible.
[0046] The surface of the cold compress layer 1 away from the patient's skin has a waterproof layer, which can effectively protect the affected area.
[0047] The medication support layer 3 has a mesh structure, with one side in contact with the patient's skin and the other side in contact with the cold compress layer 1. The medication support layer 3 has a medicated patch slot 30, within which a medicated patch 4 is placed. The medicated patch slot 30 has an adhesive backing or a clip, allowing the medicated patch 4 to be adhered to the adhesive backing or fixed to the clip. The medication support layer 3 can be divided into two pieces of the same size as the cold compress layer 1, or it can be a single piece.
[0048] The drug-aid layer 3 includes a first sub-layer and a second sub-layer. The first sub-layer is close to the skin and is a non-woven adhesive tape or cotton pad to improve comfort and prevent skin damage. The second sub-layer is close to the patch 4 and is a permeable mesh.
[0049] The insertion port 10 or the patch slot 30 can be sealed with a zipper or Velcro.
[0050] The limiting mechanism 5 includes adjustable straps 50 and fixing buckles 51. The adjustable straps 50 are in two sets of three, which are fixed on both sides of the cold compress layer 1. The fixing buckles 51 are in two sets of three, which are installed at the ends of the two sets of adjustable straps 50. The two sets of fixing buckles 51 are interlocked and fixed on the patient's limb to prevent the device from shifting.
[0051] This invention enables precise cold compresses. Through a honeycomb or segmented design of the cold compress layer 1, it ensures accurate coverage of the phlebitis or drug extravasation site. The cold compress works synergistically with medication; the cold compress constricts blood vessels, reducing drug extravasation and diffusion; the cold compress enhances the local absorption of the drug components, improving therapeutic efficacy. This invention is convenient and comfortable, with a lightweight design and breathable materials ensuring comfortable use during daily activities.
[0052] This invention can be applied during the acute phase of phlebitis, relieving swelling and pain and inhibiting the inflammatory response through cold compresses. It can also be used for the care of drug extravasation, constricting blood vessels through cold compresses to reduce drug diffusion, and combined with magnesium sulfate wet compresses or traditional Chinese medicine patches to reduce tissue damage. Furthermore, it can be used for postoperative care, reducing swelling and pain in the hand after surgery.
[0053] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
