Description

Technical Field

[0001] The present invention relates to the technical field of medical cold compress ice packs, in particular to a medical constant temperature cold compress ice pack for knee joints. Background Art

[0002] In the medical field, knee injuries are common clinical conditions, including sprains, fractures, and acute arthritis attacks, often accompanied by local swelling, pain, and inflammation. Ice compresses are widely used as a physical therapy for these conditions. Their mechanism of action includes: lowering local temperature, constricting blood vessels, reducing interstitial fluid exudation and the release of inflammatory mediators, thereby alleviating swelling and pain; and simultaneously inhibiting the excitability of nerve endings, reducing pain sensitivity, and promoting recovery at the injured site.

[0003] Chinese patent CN114569324A discloses a reusable sandwich medical constant temperature cold compress ice bag, wherein a flexible bonding cloth is provided on one outer surface of the outer protective bag of the ice bag, a sandwich is provided inside the flexible bonding cloth, and a polymer water-absorbing resin layer is filled inside the sandwich, a plurality of second Velcro strips are provided on one outer surface of the outer protective bag of the ice bag, the second Velcro strips are sewn to the outer protective bag of the ice bag by stitching, and a plurality of first Velcro strips are provided on one outer surface of the flexible bonding cloth, the first Velcro strips are sewn to the flexible bonding cloth by stitching, the patent adheres the first Velcro strips and the second Velcro strips at corresponding positions to each other, and then adheres the flexible bonding cloth to one outer surface of the outer protective bag of the ice bag, at this time, the flexible bonding cloth can be directly adhered to the part to be cooled, and after use, the flexible bonding cloth can be conveniently disassembled and cleaned, which is convenient for reuse and can effectively avoid cross infection during reuse.

[0004] This existing technology uses Velcro to secure an ice pack to the patient's joint, and the flexible adhesive cloth can be removed for cleaning. However, existing ice pack attachment technology typically uses Velcro or other fastening devices to secure the ice pack to the knee joint. To improve comfort and hygiene, some products are equipped with a removable flexible adhesive cloth for easy cleaning. However, this existing ice pack usage method has many significant drawbacks. First, during the ice pack attachment process, to ensure the ice pack is firmly attached to the joint, the ice pack is often tied too tightly. When the ice pack is directly pressed against the affected part of the knee joint, the excessive pressure directly acts on the affected tissue, not only causing great pain to the patient, affecting their comfort and treatment compliance, but also potentially hindering local blood circulation, adversely affecting recovery in the affected area and even worsening the condition. Second, existing ice packs are relatively limited in function, providing only basic cooling and cooling effects, without physical therapy. In the treatment of knee joint diseases, in addition to cold compresses to relieve acute symptoms, physical therapy is often required to accelerate recovery. However, existing ice packs cannot meet this comprehensive treatment demand, which limits their application effect in the treatment of knee joint diseases. Summary of the Invention

[0005] The purpose of the present invention is to provide a medical constant temperature cold compress ice pack for knee joints, which can reduce the pressure of the ice pack on the affected tissue by providing a ring sleeve and a drug-carrying layer, and treat the affected area by slowly releasing the medicine inside the drug-carrying layer.

[0006] In order to solve the problems of the existing technology, the present invention provides a medical constant temperature cold compress ice bag for knee joints, which can be tied to the patient's knee joint and used for cold compressing the knee joint.

[0028] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Reference Figures 1-8As shown, the present invention provides a medical constant temperature cold compress ice pack for knee joints, which can be tied to the patient's knee joint and used for cold compressing the knee joint. It includes a main body 1, and a massage component 2 for massaging the patient's knee joint is provided on the side of the main body 1 that contacts the patient's skin. The massage component 2 is used to massage the patient's knee joint. Massage can promote blood circulation around the knee joint, relieve local blood circulation problems that may be caused by cold compresses, reduce muscle tension and stiffness, improve the patient's comfort, and contribute to the recovery of the patient's knee joint. The main body 1 includes a main support bag 11, and the main body 1 also includes a medical gauze layer 18 that contacts the patient's skin. The medical gauze layer 18 mainly plays the role of protecting the patient's skin. The medical gauze layer 18 is soft and breathable, which can reduce the discomfort that may be caused by direct contact between the ice pack and the skin, and prevent the skin from being irritated or damaged due to long-term contact with the ice pack. A ring sleeve 181 is also provided at the center position of one side of the medical gauze layer 18. The main body 1 also includes a drug-carrying layer 19 that can contact the patient's skin. A limiting sleeve 182 is provided on the medical gauze layer 18 to limit the drug-carrying layer 19. The limiting sleeve 182 and the drug-carrying layer 19 are arranged at the center position of the ring sleeve 181. The ring sleeve 181 is made of silicone. The function of the ring sleeve 181 is to prevent the ice pack from applying excessive pressure on the patient's affected area. When the ice pack is tied to the knee joint, the ring sleeve 181 does not directly contact the affected area. The ring sleeve 181 can form a buffer area between the ice pack and the affected area, preventing the ice pack from directly pressing on the affected area, reducing the pressure stimulation on the affected area, and improving the patient's comfort when using the ice pack. The silicone material is soft and has a certain degree of elasticity, which can better adapt to the shape of the knee joint and provide a good cushioning effect. The drug-carrying layer 19 can contact the patient's skin and is pre-loaded with therapeutic drugs. The drug-carrying layer 19 is designed to slowly release the drug to treat the affected knee joint, alleviate pain, and promote recovery. The drug can penetrate the affected tissue through the skin, exerting its pharmacological effects, assisting with cold compress therapy, and improving the overall therapeutic effect.

[0030] When using an ice pack, first tie the main body 1 to the patient's knee joint. Make the main body 1 fit tightly on the knee joint. During the cold compress process, the medical gauze layer 18 is in direct contact with the patient's skin, playing a role in protecting the skin. Since the ring sleeve 181 is made of silicone and does not directly contact the affected area, it forms a buffer between the ice pack and the affected area, preventing the ice pack from exerting excessive pressure on the affected area and improving the patient's comfort. The massage component 2 starts working and can massage the patient's knee joint. Massage can promote blood circulation around the knee joint, improve the nutritional supply of local tissues, relieve muscle tension, reduce the discomfort that may be caused by cold compress, and help the recovery of the knee joint. The drug-carrying layer 19 is in contact with the patient's skin, and the pre-loaded drug inside acts on the affected part of the knee joint. The drug is slowly released, penetrates through the skin into the affected tissue, exerts a therapeutic effect, reduces the patient's pain, and promotes the healing and recovery of the affected area. It realizes the combined functions of cold compress, massage and drug treatment of the patient's knee joint, improves the treatment effect of knee joint diseases and the comfort of the patient.

[0031] The drug-carrying layer 19 is detachably connected to the limiting sleeve 182. The limiting sleeve 182 includes a slot for inserting the drug-carrying layer 19. The slot serves to detachably connect and positionally limit the drug-carrying layer 19. This detachable connection facilitates replacement of the drug-carrying layer 19. When the drug in the drug-carrying layer 19 is used up or the drug type needs to be changed, the drug-carrying layer 19 can be easily removed from the limiting sleeve 182 and replaced with a new one, improving the flexibility and convenience of the ice pack.

[0032] The medical gauze layer 18 is also provided with an antibacterial layer, which is a silver ion antibacterial layer, and a waterproof layer is provided on the position of the medical gauze layer 18 that contacts the patient's skin. The medical gauze layer 18 is soft and breathable, which can reduce the friction and irritation that may be caused by direct contact between the ice pack and the skin, prevent the skin from experiencing allergies, redness, swelling and other discomfort symptoms due to long-term contact with the ice pack, and play a role in protecting the patient's skin. Silver ions have broad-spectrum antibacterial activity and can effectively inhibit the growth and reproduction of various bacteria. During the use of the ice pack, due to direct contact with the patient's skin, it may come into contact with bacteria on the skin surface. The antibacterial layer can prevent bacteria from breeding and multiplying on the medical gauze layer 18, reducing the risk of complications caused by bacterial infection in patients and ensuring the safety of patients using the ice pack.

[0033] A polymeric absorbent resin layer 17 is positioned on the side of the medical gauze layer 18 facing away from the drug-carrying layer 19 to absorb condensed water. A support pad 16 is also positioned between the polymeric absorbent resin layer 17 and the main support bag 11. This polymeric absorbent resin layer 17 absorbs condensed water generated during the use of the ice pack. During the cold compress application, due to the low temperature of the ice pack, water vapor in the surrounding air condenses into water droplets on the surface of the ice pack. The polymeric absorbent resin layer 17 quickly absorbs this condensed water, preventing it from seeping out and causing inflammation in the affected area.

[0034] Several ice pack storage cavities 12 are distributed along the length direction of the main support bag 11 on one side of the main support bag 11 away from the support pad 16. The multiple ice pack storage cavities 12 are independent of each other. A detachable ice pack liner 122 is also provided inside the ice pack storage cavity 12. The ice pack liner 122 is the part that actually contains the cold compress medium (such as ice-water mixture, cold gel, etc.). The detachable design facilitates the replacement and cleaning of the ice pack liner 122. When the cold compress medium in the ice pack liner 122 fails or needs to be replaced with a different type of cold compress medium, the ice pack liner 122 can be easily removed from the ice pack storage cavity 12 and a new ice pack liner 122 can be inserted, thereby improving the flexibility and convenience of using the ice pack. An insulating bag 121 is also filled between the ice pack liner 122 and the ice pack storage cavity 12. The thermal insulation bladder 121 reduces heat exchange between the ice pack liner 122 and the external environment, slowing the temperature loss of the cold compress medium in the ice pack liner 122, extending the cold compress duration, improving the cold compress effect, and maintaining a constant temperature for a long time. The multi-layer structure prevents the ice pack liner 122 from directly contacting the patient's affected area, which could cause frostbite due to excessively low temperatures.

[0035] The ice pack storage chamber 12 is also provided with Velcro, and a protective cloth 13 is provided near the opening of the ice pack storage chamber 12 on the main support bag 11. The inner side of the protective cloth 13 is also provided with Velcro, and the protective cloth 13 can be folded so that the Velcro on the protective cloth 13 adheres to the Velcro on the ice pack storage chamber 12. The main function of the protective cloth 13 is to protect the ice pack liner 122 in the ice pack storage chamber 12, preventing the ice pack liner 122 from sliding out of the ice pack storage chamber 12 during use. It also plays a certain role in preventing dust and dirt, keeping the ice pack liner 122 clean and extending its service life.

[0036] The main support bag 11 is also equipped with a first strap 14 and a second strap 15 on either side. These straps are equipped with Velcro for interlocking attachment. When using the ice pack, the first and second straps 14, 15 are looped around the patient's knee joint and attached to each other via the Velcro, securing the ice pack to the knee joint. This prevents the ice pack from shifting or falling off during use, ensuring that the ice pack can effectively apply to the knee joint, providing cooling, massage, and medication. Furthermore, the Velcro design allows the tightness of the straps to be adjusted based on the patient's specific needs, enhancing comfort.

[0037] The massage component 2 includes two air bags 21 respectively arranged on the medical gauze layer 18, and a number of massage heads 211 for contacting the patient's skin are distributed on the air bags 21. A connecting channel 212 is also connected between the two air bags 21. The massage component 2 also includes an inflation device capable of expanding or contracting the air bags 21. The inflation device includes an air pump 22 arranged on the main support bag 11. The air pump 22 is connected to an air tube 221, and one end of the air tube 221 is connected to the air bag 21.

[0038] By pressing the air pump 22, the air pump 22 inflates the airbags 21 through the air tube 221. The air enters both airbags 21 through the connecting channel 212, causing the airbags 21 to expand. As the airbags 21 repeatedly expand and contract, the massage heads 211 on the airbags 21 squeeze and massage the patient's knee joint, promoting blood circulation around the knee joint and relieving muscle tension and pain.

[0039] Working principle: When using this medical constant temperature cold compress ice pack for knee joints, place the ice pack liner 122 filled with the cold compress medium into the ice pack storage chamber 12, then fold the protective cloth 13 so that the Velcro on its inner side adheres to the Velcro on the ice pack storage chamber 12 to secure the ice pack liner 122. Place the ice pack on the patient's knee joint, pass the first strap 14 and the second strap 15 around the patient's knee joint, adjust the tightness according to the patient's actual situation, and then secure the ice pack to the knee joint by adhering the Velcro on the first strap 14 and the second strap 15 to each other. The medical gauze layer 18 is in direct contact with the patient's skin. Its soft and breathable properties protect the skin. The waterproof layer prevents condensed water from entering the patient's affected area. The antibacterial layer inhibits bacterial growth and reduces the risk of infection. The ring sleeve 181 uses the cushioning properties of silicone to prevent the ice pack from applying excessive pressure on the affected area, thereby improving patient comfort. By pressing the air pump 22, the air pump 22 inflates the airbag 21 through the trachea 221, and the gas enters the two airbags 21 at the same time through the connecting channel 212, causing the airbag 21 to expand. When the airbag 21 repeatedly expands or contracts, the massage head 211 on the airbag 21 squeezes and massages the patient's knee joint, promoting blood circulation around the knee joint and relieving muscle tension and pain. The drug-carrying layer 19 is inserted into the slot inside the limiting sleeve 182 and fixed in a suitable position, in contact with the patient's skin. The drug in the drug-carrying layer 19 is slowly released, penetrates through the skin and enters the affected tissue of the knee joint, exerting a therapeutic effect. When the drug in the drug-carrying layer 19 is used up or needs to be replaced, it can be easily removed from the limiting sleeve 182 and inserted into a new drug-carrying layer 19 to realize the therapeutic function of the drug. The thermal insulation bag 121 reduces the heat exchange between the ice bag inner liner 122 and the external environment, reduces the temperature loss rate of the cold compress medium, and prolongs the cold compress time. During the cold compress process, the ice bag performs cold compress treatment on the knee joint.

It should be noted that a person skilled in the art may make various modifications and improvements without departing from the scope of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
