Description

Technical Field

[0001] The present invention relates to the field of traditional Chinese medicine and medical devices, and in particular to a traditional Chinese medicine medical device system for preventing pressure injuries and treating stage 1 to 3 pressure injuries. Background Art

[0002] Pressure injury, also known as pressure ulcer, bedsore, and bedsore, is a common chronic and difficult-to-heal wound in clinical practice, and is more common in patients who are bedridden or in wheelchairs for a long time.

[0003] Recent studies have shown that the incidence and prevalence of pressure injuries are increasing year by year. The United States has conducted a national census of pressure injuries every two years since 1989, and the census has found that the prevalence of pressure injuries is 9.2%-15.5%; another cohort study of 323 nursing homes found that the prevalence of pressure injuries in nursing homes can reach 38.7%; there are about 2.5 million cases of pressure injuries in the United States each year; a multicenter clinical observation study in the United Kingdom found that the prevalence of pressure injuries in the community can be as high as 7.7%, and even after removing nursing home patients with a higher prevalence of pressure injuries, the prevalence is as high as 3.8%.

[0004] my country has entered an aging society. By the end of 2021, the number of people aged 60 and above in China has reached 267 million, accounting for 18.9% of the total population; the number of people aged 65 and above has reached more than 200 million, accounting for 14.2% of the total population; it is estimated that by 2035, the total number of people aged 60 and above in my country will exceed 400 million, accounting for more than 33%, and the incidence and prevalence of pressure injuries will also increase accordingly. A multicenter clinical observation of 12 teaching hospitals or general hospitals in my country found that the prevalence of pressure injuries in hospitalized patients was 1.58% and the incidence was 0.63%. It can be inferred that the incidence and prevalence of pressure injuries may be higher in primary hospitals, community clinics, nursing homes and other places.

[0005] Although there are differences in the statistical methods of the incidence and prevalence of pressure injuries, there is no doubt that patients with pressure injuries have formed a relatively large group, and their clinical treatment is relatively difficult, the treatment cycle is long, and the cost is high, which has brought a heavy medical burden to patients and society. The annual treatment cost of pressure injuries in the UK is about 1.4-2.1 billion pounds (accounting for 4% of the national medical expenditure), and in the United States it is about 11 billion US dollars.

[0006] Pressure injury refers to a disease in which local tissue is compressed, blood circulation is impaired, local persistent ischemia, hypoxia, malnutrition lead to soft tissue ulceration and necrosis. It is also called bedsores. It is more common in middle-aged and elderly people who are bedridden. It usually undergoes three pathological changes: erythema, blisters and ulcers. Specifically:

[0007] Stage 1: Non-blanchable erythema with intact skin. The skin is intact and a non-blanchable erythema appears. Darker skin may show different symptoms. The blanchable erythema or changes in sensation, skin temperature, or firmness may appear before the skin changes are observed. Color changes in this stage do not include purple or maroon changes, as these color changes may indicate deep tissue damage.

[0008] Stage 2: Partial-thickness skin loss with exposed dermis. Partial-thickness skin loss with exposed dermis. The wound bed is active, pink or red, moist, and may present as intact or broken serous blisters. Fat and underlying tissue are not exposed. No granulation tissue, slough, or eschar. Injuries at this stage are often caused by disruption of the pelvic skin microclimate and shear forces, as well as shear forces on the heel. This stage should not be used to describe moisture-related skin injuries, such as incontinence dermatitis, fold dermatitis, medical adhesive-related skin injuries, or traumatic wounds (skin avulsions, burns, abrasions).

[0009] Stage 3: Full-thickness skin loss. Full-thickness skin loss, often with fat, granulation tissue, and involuted edges. Slough and / or eschar may be present. The depth of tissue loss varies with the anatomic location; deep wounds may develop in areas of high fat content. Undermining or sinus tracts may be present. No fascia, muscle, tendon, ligament, cartilage, and / or bone are exposed. If slough or eschar obscures the depth of tissue loss, this is an unstageable pressure injury.

[0010] Stage 4: Full-thickness skin and tissue loss. Full-thickness skin and tissue loss with visible or directly palpable fascia, muscle, tendon, ligament, cartilage, or bone. Slough and / or eschar are visible. Involuted edges, sinus tracts, and / or undermining are common. The depth of tissue loss varies with the anatomic location. If slough or eschar obscures the depth of tissue loss, it is an unstageable pressure injury.

[0011] Unstageable: Full-thickness skin and tissue loss, the extent of the injury is obscured. Full-thickness skin and tissue loss, the extent of tissue loss cannot be determined because it is obscured by slough and / or eschar. Only when enough slough and / or eschar is removed can the injury be determined to be stage 3 or 4. Stable eschar (appears as dry, tightly adherent, intact without erythema and fluctuance) on ischemic extremities or heels should not be removed.

[0012] Deep Tissue Injury: Persistent nonblanchable dark red, maroon, or purple color. A persistent nonblanchable dark red, maroon, or purple color or epidermal separation of intact or broken skin with a black wound bed or blood-filled blister. Pain and temperature changes usually precede color changes. Color may vary in darker skin. This injury results from intense and / or prolonged pressure and shear forces at the bone-muscle interface. Wounds at this stage may progress rapidly to reveal the actual extent of tissue loss or may resolve without tissue loss. If necrotic tissue, subcutaneous tissue, granulation tissue, fascia, muscle, or other deeper structures are visible, this is a full-thickness pressure injury (Unstageable, Stage 3, or Stage 4). This stage is not used to describe vascular, traumatic, neuropathic wounds, or skin disorders.

[0013] Currently, there are few drugs and medical devices that have a definite effect on pressure injuries. The present invention uses nursing pads for effective prevention of high-risk groups of pressure injuries, uses foam excipients for stage 1 pressure injuries, and uses traditional Chinese medicine ointments for effective intervention in stages 2 and 3. Summary of the invention

[0014] The purpose of the present invention is to provide a traditional Chinese medicine medical device system for preventing pressure injuries and treating pressure injuries in stages 1 to 3, which has a significant therapeutic effect on preventing pressure injuries and treating pressure injuries in stages 1 to 3.

[0015] The above technical purpose of the present invention is achieved through the following technical scheme: a Chinese medicine medical device system for pressure injury and treatment of stage 1 to 3 pressure injury, including a nursing pad for preventing pressure injury, a foam dressing for treating stage 1 pressure injury and a Chinese medicine ointment for treating stage 2 and stage 3 pressure injury, wherein the nursing pad, foam dressing and Chinese medicine ointment all include cassia twig, rhubarb, licorice, mint, angelica dahurica, forsythia, phellodendron, wormwood, Sappan wood, Millettia reticulata, borneol and the like.

[0039] In summary, nursing pads play a role in preventing people at high risk of pressure injuries, and have the following effects:

[0040] First, the nursing pad has a built-in mint fiber body in the water-absorbing layer to improve the support effect. It can be used as a cushion to avoid local blood circulation problems and prevent pressure injuries.

[0041] Second, the Chinese medicine layer and the crushed mint fiber body have a dual deodorizing effect, which can neutralize and absorb the odor in urine and feces to a certain extent;

[0042] Third, the structure of the spunlace cotton layer plays the role of loading the drug layer. At the same time, urine itself can be used as a solvent. When the discharged urine dissolves the drug layer, the drug plays a bactericidal role on the one hand, and on the other hand, it is absorbed through the skin to promote local microcirculation of the sacrum or hip, further preventing the occurrence of pressure injuries.

[0043] The foam dressing is used as a treatment device for stage 1 pressure injuries. The entire gel ointment mixed layer is distributed in a honeycomb shape through channels, which is more breathable and has a certain buffering effect. The foam layer and the gel ointment mixed layer relieve local pressure and have multiple functions of reducing swelling and relieving pain, promoting local blood circulation, and promoting the regeneration of local skin and subcutaneous muscle layer. At the same time, compared with the foam dressings in the prior art, the combination of colloid and carrier material has a stronger buffering effect. The foam layer plays the role of connecting the gel ointment mixed layer. At the same time, for the first time, Chinese medicine ingredients that can adjust the microenvironment, promote blood circulation, reduce swelling and relieve pain, promote blood circulation and blood stasis, and promote the regeneration of local skin and subcutaneous muscle layer are added to the carrier, which has a significant effect on pressure injuries. The Chinese medicine ointment has a good therapeutic effect on stage 2-3 pressure injuries. BRIEF DESCRIPTION OF THE DRAWINGS

The channel 31 evenly divides the gel ointment mixing layer 3 into a honeycomb shape on the horizontal plane.

[0107] The sealing layer 4 is arranged on the upper surface of the gel-ointment mixed layer 3. The sealing layer 4 is a plastic film. The sealing layer 4 is heat-pressed and sealed or bonded to the outer side of the non-woven fabric layer 1. When in use, the sealing layer 4 is torn off and then the gel-ointment mixed layer 3 is attached to the wound.

[0108] like Figures 7 to 11 As shown:

[0109] Case 1: If Figure 7 As shown, Zhang, male, 82 years old, was bedridden during the recovery period after hip replacement. He had a pressure injury about 4 cm from the anus to the left buttocks of the sacrum and coccyx, with a range of 2 cm×2 cm, and stage 1. After disinfecting the wound, the gel foam excipient of the present invention was given, and the dressing was changed once a day. The wound healing was observed. From the second to the sixth day, it was seen that the wound was swollen and scabs formed, and no purulent secretions were exuded; on the seventh day, the scabs fell off by themselves, and the surface was flat and without boundaries.

[0110] Case 2: If Figure 8 As shown, Peng, male, 84 years old, was bedridden for a long time after cerebral infarction, with multiple pressure injuries in the sacral coccyx, stage 2. After cleaning the wound, the gel foam excipient of the present invention was given, and the dressing was changed once a day. The wound healing was observed. On the third and fifth days, the wound was obviously swollen, healed, and scabbed, without purulent secretion; on the seventh day, the scab fell off by itself, and the surface was flat and without boundaries.

[0111] Case 3: If Fig. 9 As shown, Chen, female, 80 years old, was bedridden due to left hemiplegia after cerebral infarction, and pressure injury was produced in the posterior part of the left lower limb, with a range of 3cm×2cm, and stage 2. After disinfection and cleaning of the wound, the gel foam auxiliary material of the present invention was given, and the dressing was changed once a day. The wound healing was observed.

[0114] Embodiment 2:

[0115] like Figure 3As shown, the difference between Example 1 and Example 2 is that the structure of the foam layer 2 is different. The foam layer 2 corresponds to the gel ointment mixed layer 3 and both are hexagonal, that is, the structure of the channel 31 penetrates the surface of the non-woven fabric layer 1, increasing the depth of the channel 31 and improving the overall breathability effect.

[0116] Embodiment 3:

[0117] like Figures 4 to 6 As shown, a nursing pad containing traditional Chinese medicine ingredients is composed of a four-layer structure from top to bottom, which includes a spunlace cotton cloth layer 61, a non-woven fabric layer, a water-absorbing layer 63 and a waterproof layer in sequence. The sides of the four-layer structure are connected by a connecting area 65. The nursing pad is rectangular or hexagonal as a whole, that is, the spunlace cotton cloth layer 61, the non-woven fabric layer, the water-absorbing layer 63 and the waterproof layer are all rectangular or hexagonal.

[0118] The nonwoven fabric layer is disposed below the spunlace cotton fabric layer 61 .

[0119] The water-absorbing layer 63 is mixed with crushed mint fiber body 66, and the water-absorbing layer 63 is a water-absorbing cotton layer or a fluff pulp layer. The thickness of the water-absorbing layer 63 is 0.5mm-5mm, the diameter of the crushed mint fiber body 66 is 0.1mm-0.3mm, and the length of the crushed mint fiber body 66 is 1mm-2mm. The diameter and length of the crushed mint fiber body 66 vary according to the crushing fineness and material selection. At the same time, the water-absorbing layer 63 can also be replaced by a non-woven fabric blended with mint fiber, but the supporting and deodorizing and cooling effects are poor.

[0120] The waterproof layer 64 is arranged at the bottom of the water-absorbing layer 63. The waterproof layer 64 is a PE film. The waterproof layer 64, the hydrophilic non-woven fabric layer 62 and the spunlace cotton fabric layer 61 are bonded and fixed in the connecting area 65 by adhesive. The waterproof layer 64 and the hydrophilic non-woven fabric layer 6 are connected outside the positive projection area of ​​the water-absorbing layer 63. A gap is formed between the hydrophilic non-woven fabric layer 62 and the spunlace cotton fabric layer 61. The gap allows air to flow, thereby ensuring the breathability of the nursing pad.

[0121] like Figure 4 As shown, a Chinese medicine layer is arranged inside or on the surface of the spunlace cotton cloth layer 61; the spunlace cotton cloth layer 61 is not a spunlace non-woven fabric, and the spunlace non-woven fabric has the advantages of being breathable and having holes on the inner surface, which can prevent the skin from being suffocated on the surface of the care pad. During the molding process of the spunlace cotton cloth layer 61, hollow holes are formed in the spunlace cotton cloth layer 61. Since the hollow holes are randomly distributed, the density of the hollow holes in the embodiment is 20-40 / cm2, and the diameter of the hollow holes is 1mm-3mm. The Chinese medicine layer is arranged as follows.

[0122] The preparation method of the Chinese medicine layer is as follows: the following components in parts by weight: 1-4.5 parts of cassia twig, 3-30 parts of rhubarb, 1.5-9 parts of liquorice, 6-12 parts of burdock fruit, 3-6 parts of mint, 3-9 parts of angelica dahurica, 6-15 parts of forsythia, 5-30 parts of viola yedoensis, 3-12 parts of phellodendron, 3-9 parts of wormwood, 3-9 parts of sappan wood, 9-15 parts of millettia reticulata, 6-12 parts of julibrissin bark, and 0.1-0.3 parts of borneol.

[0123] Preparation and implementation method: Weigh 3 parts of cinnamon twig, 9 parts of rhubarb, 3 parts of liquorice, 9 parts of burdock fruit, 6 parts of mint, 6 parts of angelica dahurica, 9 parts of forsythia, 15 parts of viola yedoensis, 9 parts of phellodendron, 9 parts of wormwood, 6 parts of sappan wood, 12 parts of millettia reticulata, 9 parts of julibrissin bark, 0.1 part of borneol, and 450 parts of water.

[0124] The above-mentioned cassia twig, rhubarb, liquorice, burdock fruit, mint, angelica dahurica, forsythia suspensa, viola yedoensis, phellodendron, wormwood, sappan wood, millettia reticulata, julibrissin bark, borneol, and aloe were mixed and crushed, boiled for 1 hour, and filtered; 6 times the amount of water was added to the filter residue, boiled for half an hour, and filtered; 4 times the amount of water was added to the filter residue, boiled for half an hour, and filtered; the filtrates were combined to form a hot extract.

[0125] The hot extract can be bonded to the spunlace cotton fabric layer 61 in a variety of ways.

[0126] The first method is to spray the hot leaching liquid on the inner side of the spunlace cotton fabric layer 61 during the conveying process of the spunlace cotton fabric layer 61 by the guide roller, and then dry it after spraying;

[0127] The second method is to apply a certain concentration of hot leached liquid to the inner side surface or both sides of the spunlace cotton fabric layer 61 by roller coating during the conveying of the spunlace cotton fabric layer 61 by the guide roller, and then dry the leached liquid after coating.

[0128] The third method is to immerse the spunlaced cotton fabric layer 61 in a water pool containing hot leaching liquid during the conveying process of the guide roller, and then pass through a drying box for drying during the conveying process;

[0129] The fourth method is to dry the hot leaching liquid to form particles. During the transportation process, the spunlace cotton fabric layer passes through the particles on the inner side, and a certain amount of particles adhere to the inner side of the spunlace cotton fabric layer.

[0130] Then, through the above four methods (manual dipping or coating of the hot extract solution may also be adopted), a Chinese medicine layer is formed on the inner surface, outer surface or inside of the Chinese medicine layer.

[0131] When in use, the nursing pad should be replaced every 8 to 12 hours, or if it is contaminated after urination or defecation.

[0132] The beneficial effects of the present invention are described below in conjunction with clinical trial data.

[0133] Data: From May 2018 to May 2023, the inventor collected 120 long-term bedridden patients with high risk of Braden score (10-12 points), including 68 males and 52 females, aged 67-98 years old, with an average observation period of 12 months. They were randomly divided into an experimental group of 64 cases and a control group of 56 cases. There was no significant difference in gender, age, weight, etc. between the two groups, and they were comparable.

[0134] Treatment method: The experimental group was implemented according to the implementation method, with long-term use and an observation period of 12 months. The control group used non-drug-loaded adult nursing pads, with long-term use and an observation period of 12 months. Both groups of patients used the same air mattress.

[0135] Observation items: The incidence of pressure injuries during the observation period

[0136] Comparison of the therapeutic effects between the two groups: Within 12 months, 3 cases of pressure injury occurred in the experimental group, with an incidence rate of 4.69%; Within 12 months, 6 cases of pressure injury occurred in the control group, with an incidence rate of 10.71%. It can be seen that the nursing pad can effectively prevent pressure injuries.
