Description

Technical Field

[0001] The present invention relates to the technical field of surgical instruments, and in particular to a Chinese medicine powder, a blood coagulation dressing, a hemostatic bandage, a monitoring device and an application method. Background Art

[0002] According to statistics, there are 1 billion casualties in various accidents every year, and severe bleeding from wounds can easily cause disability and death. The mortality rates of battlefield soldiers and casualties from daily accidents due to severe bleeding are 83.1% and 35.7% respectively. It is reported that the medical expenses caused by this are as high as 13.2 billion US dollars each year. At present, the hemostasis treatment of the wounded before admission or emergency treatment in China is still basically based on traditional methods, such as manual packing, tourniquets and other methods. Artificial compression hemostasis has the disadvantages of easy fatigue of the hemostatic person, difficulty in lasting, and unstable compression. Tourniquets are widely used in emergency medical treatment, but they face the risk of mechanical nerve damage during use. The above methods have poor hemostasis effects, and cannot monitor relevant preoperative indicators, and at the same time, they do not have a coagulation effect on the wound.

[0003] In addition, the common hemostatic materials and devices provided by the prior art have the disadvantages of low hemostatic efficiency and high price. The complicated preparation process and high price also make it difficult to put them into large-scale production and market. What's worse, the particles of the products are easy to fall into the blood circulation system, causing the safety risk of embolism.

[0004] During the postoperative wound healing process, the wound surface is easily infected by pathogens, causing inflammation, which leads to slow wound healing or even no wound healing. It is now difficult to monitor and treat the wound in time after surgery. Antibiotics and biocides are still the main methods for treating infections, but their widespread use and abuse reduce the sensitivity of bacterial strains and lead to the emergence of drug-resistant bacteria. Summary of the invention

[0005] The purpose of the present invention is to provide a Chinese medicine powder, a coagulation dressing, a hemostatic bandage, a monitoring device and an application method, which are used to solve the shortcomings of the artificial filling and hemostasis provided by the prior art, such as the hemostatic person is easily fatigued, not easy to last, and the pressure is unstable, and the common hemostatic bandage can only provide a single hemostatic function and cannot promote wound healing. In addition, it can also solve the problem that the existing hemostatic device cannot record and display the hemostatic situation and wound inflammation in real time; furthermore, it can also solve the problems that the existing hemostatic device is expensive and cannot be put into large-scale production and market launch. The hemostatic monitoring device provided by the present invention can be used for first aid in case of heavy bleeding.

It needs to be further explained that the particle size of the powder passing through a 100-mesh sieve is less than or equal to 150 microns.

[0049] In a second aspect, the present invention further provides a coagulation dressing, which is made by dipping a dressing substrate in a Chinese medicine extract for a preset time, followed by drying and sterilization. The Chinese medicine extract is made by drying, decocting, extracting and mixing the Chinese medicine powder provided in the first aspect.

[0050] In practical applications, Chinese medicine extracts are made through the following process steps:

[0051] S10. The Chinese medicine powder was dried at 105°C for 2 hours;

[0052] S11. Take an appropriate amount of dried Chinese medicine powder, add water and boil for 2 hours, repeat three times, filter and remove the residue to obtain the decoction;

[0053] S12. Extract the decoction, mix the decoction with a solvent (water, ethanol of different purity), put it in a sealed container, stir, and let it stand for 48 to 168 hours to obtain the extract, separate and purify it, separate the two phases, and obtain the medicinal liquid stock solution; the decoction, medical alcohol and water are mixed; the mass ratio of the decoction, medical alcohol and water is 1:2:2 (generally the Chinese medicine stock solution accounts for 20%); and obtain the Chinese medicine prescription extract.

[0054] S13. The extract of the Chinese herbal medicine prescription is mixed with medical alcohol to obtain a Chinese herbal medicine extract; the mass of the medical alcohol is 8 times the mass of the extract of the Chinese herbal medicine prescription.

[0055] The process for preparing the blood coagulation dressing by immersing the dressing substrate in the Chinese medicine extract for a preset time, drying and sterilizing is as follows:

[0056] S20. After cleaning the dressing substrate with physiological saline, wash with pure water until the surface is free of ions;

[0057] S21. The dressing substrate treated by S20 is added to a sodium hyaluronate solution and dried under vacuum; the mass of the sodium hyaluronate is 15 times the mass of the dressing substrate;

[0058] S22. The dried dressing substrate of S21 was added to the Chinese medicine extract and immersed for 6 hours;

[0059] S23. The dressing impregnated with S22 is dried and sterilized with ethylene oxide, the residual amount of which is no more than 10 μg / g. The product has no skin irritation reaction, no delayed hypersensitivity reaction, and no cytotoxicity, thereby obtaining a traditional Chinese medicine dressing.

[0060] Thirdly, see Figures 1 to 4 The present invention also provides a hemostatic bandage 1, comprising a cuff 10, wherein one end of the cuff 10 is a fixed area 11, the other end is an air bag 12, and the functional area is located between the air bag 12 and the fixed area 11. The air bag 12 is provided with an inner inflation tube 13; the functional area is sequentially attached with a flexible film sensor 14 and a coagulation dressing 15 from bottom to top, and the area of ​​the coagulation dressing 15 is larger than the area of ​​the flexible film sensor 14; the coagulation dressing 15 is the coagulation dressing 15 described in the second aspect.

[0061] The hemostatic bandage 1 provided by the present invention effectively combines pneumatic compression hemostasis with a hemostatic dressing of a traditional Chinese medicine formula to monitor the hemostasis, healing and anti-inflammatory effects of wounds before and after surgery.

[0062] The coagulation dressing 15 is formed by soaking the Chinese medicine extract made of Chinese medicine powder. The coagulation dressing 15 adheres to the functional area of ​​the cuff 10. When used, the coagulation dressing 15 is positively covered on the wound, and the hemostatic bandage 1 is wrapped around the rear end of the wound to be fixed. At the same time, the inflation adjustment device 2 is started to apply effective hemostatic pressure to the airbag 12. Under the action of the inflation pressure, the hemostatic effect is achieved to the greatest extent. At the same time, the coagulation dressing 15 can also promote wound healing. In this way, the double guarantee achieves the purpose of effective and rapid hemostasis. In addition, the coagulation dressing 15 with the safety characteristics of traditional Chinese medicine can also timely reduce inflammation for the wound and avoid other adverse reactions caused by the wound.

[0063] In practical applications, the coagulation dressing 15 of the hemostatic bandage 1 provided by the present invention can be directly wrapped around the wound. Compared with the hemostatic bandage 1 provided in the prior art which is wrapped around the proximal end of the wound, it can effectively avoid problems such as nerve damage to the muscles outside the wound.

[0064] The hemostatic bandage 1 provided by the present invention can be applied to traumatic hemorrhage, and can be quickly prepared and used, which can greatly reduce the initial mortality rate of patients. In addition, it can be applied to large-area trauma and various irregular wounds, and can be mass-produced and widely marketed.

[0065] After wearing the hemostatic bandage 1 on the patient's wound and selecting the appropriate pressure (the effective hemostatic pressure for adults' upper limbs is 225mmHg, and the lower limbs is 450mmHg; the upper limbs of children are 120mmHg, and the lower limbs of children are 225mmHg), automatic inflation and hemostasis are performed. A flexible film sensor 14 is installed on the inner side of the hemostatic cuff 10. The flexible film sensor 14 judges the hemostasis of the wound by the difference in pressure at both ends of the detection device. For example, if the differential pressure reference value>160g, it can be judged as bleeding. At the same time, a temperature sensor is connected to monitor whether the wound is inflamed (the temperature rises compared to the initial temperature, that is, attention should be paid). At the same time, it has a Bluetooth setting, and connecting Bluetooth can be monitored on the mobile phone.

[0066] See also Figure 3 and Figure 4 The flexible film sensor 14 may specifically include a flexible substrate 140, a first electrode 141, a second electrode 142, and a film material 143. The first electrode 141 outputs a pressure signal, and the second electrode 142 outputs a temperature signal. The first electrode 141 outputs a signal using a first wire 144, and the second electrode 142 outputs a signal using a second wire 145.

[0067] As a possible implementation, the flexible film sensor 14 is attached to the inner surface of the functional area of ​​the cuff 10; and / or the blood coagulation dressing 15 is attached to the flexible film sensor 14. This arrangement facilitates replacement of the blood coagulation dressing 15 and the flexible film sensor 14.

[0068] As a possible implementation, the sensitivity of the flexible film sensor 14 is 120 mmHg-750 mmHg, for example, 120 mmHg, 200 mmHg, 300 mmHg, 400 mmHg, 500 mmHg, 600 mmHg, 700 mmHg or 750 mmHg.

[0069] The main body specifications of the hemostatic bandage 1 are large size 70cm*25cm, medium size 56cm*22cm, and small size 40cm*18cm; the specifications of the internal air bag 12 of the inflatable cuff 10 and the Chinese medicine dressing are: large size 34cm*24cm, medium size 27cm*21cm, and small size 19cm*17cm.

[0070] The hemostatic effect of hemostatic bandage 1 in the rabbit ear artery bleeding model was significantly different from that of Panax notoginseng powder and warfarin, as follows:

[0071] (1) From the perspective of hemostasis time, the average hemostasis time of the hemostatic bandage 1 provided by the present invention is 46.8±.1s, while that of Panax notoginseng powder is 105.2±15.8s, which is 124% shorter and 100% shorter than that of warfarin, which is 94±5.2s;

[0072] (2) From the perspective of blood loss for hemostasis, the blood loss for hemostasis of the hemostatic bandage 1 provided by the present invention is 1.5±0.2 g, which is significantly reduced compared to 2.5±0.2 g for Panax notoginseng powder and 2.0±0.1 g for warfarin;

[0073] (3) From the perspective of in vitro coagulation time, the average in vitro coagulation time of the hemostatic bandage 1 provided by the present invention is 138.2±17.3s, that of warfarin is 201.7±18.7s, and that of Panax notoginseng powder is 283.2±17.4s. It can also be seen that the in vitro coagulation time (138.0±17.4s) of the hemostatic bandage 1 provided by the present invention is significantly shorter than that of warfarin (201.1±18.7s) and Panax notoginseng powder (283.1±10.4s) by 45.7% and 105.1%, respectively, indicating that the in vitro coagulation effect is optimal.

[0074] The effective hemostatic pressure of the hemostatic bandage 1 is 120 mmHg to 450 mmHg.

[0075] In a fourth aspect, the present invention also provides a monitoring device, see Figure 5 , comprising a hemostatic bandage 1, wherein the hemostatic bandage 1 is the hemostatic bandage 1 described in the third aspect;

[0076] The inflation adjustment device 2 is connected to the inner inflation tube 13 of the hemostatic bandage 1 through the outer inflation tube 20, and can controllably apply effective hemostatic pressure to the airbag 12; for example, the effective hemostatic pressure for the upper limbs of adults is 225 mmHg, and for the lower limbs is 450 mmHg; the effective hemostatic pressure for the upper limbs of children is 120 mmHg, and for the lower limbs of children is 225 mmHg.

[0077] And a monitoring terminal is used to receive the pressure signal and temperature signal transmitted by the flexible film sensor 14, determine the hemostasis result according to the pressure signal, and determine the wound inflammation based on the temperature signal. When the pressure signal>160g, it can be judged as bleeding, otherwise it can be judged as no bleeding. If the temperature rises compared to the initial temperature, it can be judged as wound inflammation, and the initial temperature can be human body temperature.

[0078] In a fifth aspect, the present invention further provides an application method of the monitoring device, comprising the following steps:

[0079] S10. The blood coagulation dressing 15 is positively covered on the wound, and the hemostatic bandage 1 is wrapped around the wound site and fixed at both ends;

[0080] S11. Determine effective hemostatic pressure based on the patient's age and wound location;

[0081] S12. Start the inflation adjustment device 2 to apply effective hemostatic pressure to the airbag 12;

[0082] S13. The monitoring terminal obtains the pressure signal in real time. When the pressure difference is greater than the reference value, it is judged as bleeding; and when the pressure approaches the reference value, it is judged that the hemostasis is completed;

[0083] S14. The monitoring terminal obtains the temperature signal in real time. When the temperature is greater than the initial temperature, it is determined that the wound is inflamed. Otherwise, it is determined that the wound is not inflamed.

[0084] The hemostasis monitoring device provided by the present invention is suitable for pre-hospital emergency treatment and can be widely deployed in public places such as airports, railway stations, etc. for pre-medical emergency measures. It can stop bleeding immediately due to its convenient operation, and can greatly reduce the amount of bleeding before the ambulance and professionals arrive at the scene.

[0085] Uncontrolled bleeding can lead to serious problems such as hypotension, organ dysfunction, and even death. The development of efficient and rapid hemostatic equipment can not only reduce the health risks caused by excessive blood loss, but also reduce medical expenses such as blood transfusion, grasp the golden emergency time, and alleviate the problem of tight national blood banks. The industrialization and marketization of efficient hemostatic instruments that are simple to operate, can be deployed on a large scale, monitor bleeding in real time, and are biosafe will produce good social and economic benefits. The hemostatic monitoring device provided by the present invention is aimed at the urgent needs of trauma patients, patients with abnormal coagulation, and doctors for hemostatic materials for moist tissue adhesion wound closure. It uses external pressure and Chinese medicine patches to develop a new type of first aid hemostatic bandage, which is widely used in clinical hemostasis tests. This technology fundamentally solves the problem of reduced survival rate due to massive bleeding, reduces blood loss and obtains more pre-hospital emergency time under the premise of high biosafety to protect the life and health of the wounded.

[0086] Through traditional Chinese medicine, the healing ability is enhanced. Traditional Chinese medicine is safe and effective. Through the flexible film sensor and Bluetooth device, real-time monitoring of hemostasis and inflammation can be achieved. Through the inflatable airbag set in the bandage, the elastic force of the airbag can be used to apply gentle pressure, and the pressure can be flexibly adjusted according to the needs of clinical treatment. Compared with the existing hemostatic bandages for patients with severe bleeding due to trauma, this inflatable pressure-sensing first-aid traditional Chinese medicine hemostatic bandage is easy to use, safer and more reliable, with a higher degree of automation, good coagulation ability, strong healing ability, stable wounds without secondary damage, stronger functions, and better hemostatic effects.

[0087] At present, in the medical emergency of limb trauma, the main methods of dressing and gauze bandage are used to stop bleeding and prevent wound infection. This method wastes time when using gauze bandage, has poor compression hemostasis, increases the patient's bleeding volume, and adds difficulties to medical treatment; the existing hemostatic bandages are usually operated manually, which is not only inconvenient to use, but also has poor hemostatic effect; at the same time, the existing hemostatic bandages have a simple structure, that is, a tourniquet, and when the patient uses it, because the arm is not fixed, it is easier to move, which affects the hemostatic effect. The commonly used hemostatic method is manual compression hemostasis, which has the disadvantages of easy fatigue of the hemostatic person, difficulty in lasting, and unstable compression.

[0088] The raw materials are abundant and easy to obtain, and the price cost is low. The main raw materials of the product are dressings, Chinese medicinal materials and flexible film sensors. The first two are characterized by wide sources and environmental protection, and the other three are characterized by low prices.
