Technical Field
The invention relates to the technical field of foot therapeutic apparatuses, in particular to a sealing device for a foot therapeutic apparatus and the foot therapeutic apparatus with the sealing device.
Background
The world health organization defines a diabetic foot as a foot infection, foot ulcer and/or deep tissue destruction caused by neuropathy and vasculopathy of the lower limbs, and is one of the serious complications of late stage diabetes. The diabetes patients have poor long-term blood sugar control, cause in vivo metabolic disorder and cause angiopathy, particularly relate to foot neuropathy, abnormal sensation and protective function loss caused by serious insufficient foot blood supply, are very easy to suffer from ulcer and infection, and are not longer and even face serious risks of amputation. Medical reports have indicated that amputation due to diabetic feet accounts for more than half of all amputations, and that the feet see a great risk of the disease. Besides the conscious factors of the patients themselves, the main reasons for the above-mentioned situation are: 1. the prior art is deficient in preventive means for delaying severe arterial occlusion; 2. in the prior art, the treatment means for the wounds of the diabetic foot, particularly the wounds of the foot, is very limited and the effect is not ideal.
Ozone (O)3) Also known as superoxide, is oxygen (O)2) Is a light blue gas with special odor at normal temperature. The ozone is mainly distributed in the atmosphere of an stratosphere with the height of 10-50 km, and the maximum value is between 20-30 km. The stability is poor at normal temperature and normal pressure, and the oxygen can be automatically decomposed into oxygen. Ozone has the taste of green grass, is beneficial to human bodies when being inhaled in a small amount, and has certain harm to human health when being inhaled in an excessive amount. Non-flammable and pure. The artificial production of ozone is generally carried out by electrolysis or ultraviolet irradiation.
Ozone has application value in the medical field, and mainly utilizes the characteristic of effective sterilization and disinfection. Ozone is a strong oxidant, the molecule of which is extremely unstable, can be decomposed to generate monatomic oxygen (O) and hydroxyl (OH) with extremely strong oxidizing power, is a unique bacterium-melting preparation, can be quickly melted into cell walls, destroys the internal structures of microorganisms such as bacteria, viruses and the like, and has extremely strong killing effect on various pathogenic microorganisms. The sterilization process belongs to biochemical oxidation reaction. Specifically, the effect is mainly realized through the following forms: (1) the ozone can oxidize and decompose enzyme required by glucose in the bacteria to inactivate and kill the bacteria; (2) acting on nuclear substances in bacterial cells, such as purine and pyrimidine in nucleic acid, destroying organelles, DNA and RNA of the nuclear substances, and destroying the metabolism of the bacteria to cause the death of the bacteria; (3) ozone reacts with lipid double chains of bacterial cell walls, penetrates cell membrane tissues, invades cells, and acts on lipoprotein of an outer membrane and lipopolysaccharide inside the outer membrane to enable bacteria to be dissolved and killed due to permeability distortion; (4) ozone acts on the 4 polypeptide chains of the capsid protein of the virus and damages the RNA, destroying the proteins that form it. After oxidation of the phage by ozone, the coat is broken into fragments, which release ribonucleic acids that interfere with their adsorption onto the registers. However, ozone is easy to overflow and disperse in the medical application process if the operation is not proper, so that the environment is seriously polluted and even the surrounding personnel are poisoned.
Therefore, an improved technical solution should be provided to solve the corresponding technical problems in the prior art.
Disclosure of Invention
The object of the present invention is to provide a series of structures which can overcome the above-mentioned problems of the prior art and to a certain extent prevent the ozone from escaping from the device for ozone gas treatment, especially from the treatment with gaseous ozone. The invention provides a plurality of technical schemes to achieve the aim of the invention.
Specifically, the method comprises the following steps:
the invention provides the following technical scheme:
a sealing device for a foot treatment apparatus and a foot treatment apparatus having the same.
Wherein the sealing device for a foot treatment apparatus comprises: the airtight sleeve comprises a treatment box connecting port end and a limb inlet end; further comprising: the sealing element is fixedly arranged at the end of the limb extending inlet and comprises a tightening belt body and an annular air bag positioned on the outer side of the circumference of the tightening belt body, and the annular air bag is connected with an air source.
The foot therapeutic apparatus comprises a therapeutic bin and an electric bin, wherein the therapeutic bin comprises a therapeutic box, and a sealing device for the foot therapeutic apparatus is arranged on the therapeutic box; the treatment box comprises a box opening arranged at the top, and a connection port end of the treatment box of the airtight sleeve of the sealing device is hermetically connected with the box opening.
The treatment box and the airtight sleeve form a treatment space together, and the treatment space is used for storing feet and/or legs of a patient with wound surfaces and constructing an ozone medical environment. When in use, the limb extending end is used for the patient to extend the limb with the wound surface into the treatment space for treatment, and the sealing element can ensure that the treatment space is relatively closed so as to ensure that the ozone in the treatment space can not be diffused. The sealing element mainly comprises two parts, namely a tightening belt body and an annular air bag positioned at the periphery and outside the tightening belt body. The tightening belt body is utilized to enable the human body and the airtight sleeve to establish a primary sealing state at the position of the limb inlet end, and then the tightening belt body is supplemented and pressurized by utilizing the gradually expanded annular air bag, so that a double-layer sealing state is established, and the condition that ozone cannot overflow and disperse from a treatment space is ensured.
The whole treatment time is generally longer, usually lasts for several minutes to tens of minutes, the limbs of a person lose part of elasticity (such as swelling and collapse) at the extruded part, if the tightening belt body is used, the high sealing degree in the whole treatment process cannot be ensured, and the blood circulation is easy to be unsmooth due to the too tight force application. The annular balloon serves as one of the necessary components of the seal, the core points being the greater elasticity of the annular balloon compared to the tightening of the band and the flexibility of tightness adjustment throughout the treatment.
Preferably, an ozone color-changing reagent layer is arranged on the surface of the annular air bag; it is further preferred that the annular balloon surface is provided with a layer of aqueous potassium iodide solution in a wet state. Whether ozone leaks or not can be judged by surrounding personnel through smell sense, but the ozone is easily interfered by other factors, and is not easy to be obviously perceived or can be always distinguished particularly when trace ozone leaks for a long time. By arranging the ozone color-changing reagent layer on the surface of the annular air bag, surrounding personnel such as patients can visually observe and distinguish, and the reliability of identification is improved. Ozone discoloration reagent preferably, an aqueous solution of potassium iodide can be used. According to the chemical equation: o is3+2KI+H2O＝O2+I2+2KOH, it can be seen that when elemental iodine is generated, a color change, its color change amount or contrast, i.e., the amount of reaction of ozone, is visually observed. Before treatment, the surface of the annular air bag is coated with a potassium iodide aqueous solution to form a wet liquid layer film. In addition, the treatment time can be determined according to the actual treatment timeThe length of the film is that a proper amount of thickening agent is added into the potassium iodide aqueous solution to adjust the thickness of the film and ensure the volatilization time.
Preferably, the sealing device for the foot therapeutic apparatus further comprises a PLC air pressure adjusting system, wherein the PLC air pressure adjusting system comprises a pressure sensor, a PLC controller, a relay and an electromagnetic valve; the signal output end of the pressure sensor is connected with the signal input end of the PLC, the signal input end of the relay is connected with the signal output end of the PLC, the signal output end of the relay is connected with the electromagnetic valve, and the electromagnetic valve is connected with an air source; the pressure sensor is a flexible pressure sensor and is arranged between the tightening belt body and the annular air bag. The PLC air pressure adjusting system is used for adjusting the air pressure of the annular air bag at the beginning of treatment or in the whole treatment process, so that proper internal pressure is obtained, and reasonable sealing and human limb bearing relation are constructed and balanced. The flexible pressure sensor is positioned between the tightening belt body and the annular air bag and is mainly used for detecting the mutual pressure relation between the annular air bag and the tightening belt body, and the obtained data reality degree, change interval and reliability are all larger than those of the flexible pressure sensor which is directly arranged between a human limb and the tightening belt body, particularly larger than those of the flexible pressure sensor which is caused by overlong treatment time and changes the skin elasticity or appearance form of the human limb even seriously.
In order to ensure the adjustability of the gas storage in the annular airbag, it is more preferable that a micro-vent hole or a micro-vent seam is formed on the annular airbag. The tiny and continuous gas release can ensure that the air pressure in the annular air bag is always in a dynamically variable condition, thereby increasing the overall sealing reliability and comfort degree of the sealing element.
Preferably, the flexible pressure sensor comprises a flexible substrate, and the material of the flexible substrate is selected from a metal material or a resin material; the metal material is selected from any one or a plurality of lamination compounds of aluminum or aluminum alloy, copper or copper alloy, galvanized steel, nickel-based alloy, chromium-nickel-iron alloy, titanium or titanium alloy; the resin material is selected from one or more of ABS, POM, butyl synthetic rubber, perfluororubber, chlorinated polyvinyl chloride, ethylene propylene diene monomer rubber, tetrafluoroethylene, modified tetrafluoroethylene, alicyclic epoxy resin, ethylene-propylene, fluorosilicone rubber, fluorinated rubber, LDPE, polyvinylidene fluoride, polyacrylate, PC, polysulfide, polyimide, polyurethane, PTFE, PVC, PVDF, PP/EPDM vulcanized rubber, silicone resin and polyethylene. Since flexible pressure sensors have the potential to come into contact with ozone, even continuously, the material used for the substrate should be somewhat inert with respect to ozone. It is also possible if the substrate itself is not inert to ozone, but its surface is correspondingly coated or surface-treated. Therefore, more preferably, the surface of the flexible substrate is coated with a sodium tetrafluoroethylene layer; when the flexible substrate is made of aluminum or aluminum alloy, the surface of the flexible substrate is subjected to micro-arc oxidation or low-temperature oxidation treatment.
Preferably, the number of the flexible pressure sensors is 2-4. The arrangement of a plurality of flexible pressure sensors can reduce the specific specification degree of each pressure sensor, namely, most conventional flexible pressure sensors can be suitable for the scene. The technical scheme is designed for redundancy on the other side surface, namely when signal acquisition or signal transmission bad conditions exist in not all the flexible pressure sensors, the whole data acquisition is not influenced. More preferably, the flexible pressure sensors are arranged symmetrically on the circumference. In the practical use, the pressure signal transmitted by the flexible pressure sensor can also be used for judging the specific skin condition of the sealed part of the limb of the person.
Preferably, a bulge is arranged on one side surface of the tightening belt body facing the annular air bag; the flexible pressure sensor includes a pressure sensitive layer region with a protrusion aligned with the pressure sensitive layer region. By utilizing the technical content provided by the scheme, the protrusion plays a role in improving the touch tightness between the pressure sensitive layer of the flexible pressure sensor and the tightening belt body, and the virtual connection condition caused by factors such as angle, tightness, surface structure shape of human body and the like can be avoided. Generally, the thickness of the bulge is low, so that the collected pressure value and the pressure values of other parts do not have obvious deviation, and the obvious discomfort of the human limb or the injury of the surface of the limb is avoided. More preferably, the protuberance is a solid structure or the protuberance contains a balloon therein.
The invention also provides a foot therapeutic apparatus, which comprises a therapeutic bin and an electric bin, wherein the therapeutic bin comprises a therapeutic box, and the sealing device for the foot therapeutic apparatus is arranged on the therapeutic box; the treatment box comprises a box opening arranged at the top, and a connection port end of the treatment box of the airtight sleeve of the sealing device is hermetically connected with the box opening.
Conventionally, the treatment chamber and the electrical chamber are designed separately, but can be combined with each other to form a structure which is integrated with the appearance. If a frame body is designed, the frame body can provide fixed bearing for the treatment bin and the electric bin, and when the foot treatment instrument is a conventional fixing device, the foot treatment instrument can be designed to be fixed in a wall type or a bed type, and even can be combined with a bed, a table or a cabinet body. When designed as a mobile unit, the frame body is usually fixed with wheels.
Preferably, the treatment cabin further comprises an outer shell, and the treatment box is positioned in the outer shell; the electric bin comprises a mounting rack, an ozone generator and an ozone generation controller, wherein the ozone generator is fixedly connected to the mounting rack; the ozone generator is communicated with the interior of the treatment box through a first air passage. The ozone generator has various generation principles, for example, when the ultraviolet irradiation method is adopted, the ozone generator usually comprises an oxygen generating device and an ultraviolet irradiation device, and the oxygen generating device is usually obtained by preferably adopting a molecular sieve.
Preferably, the installation frame is fixedly provided with a liquid medicine atomization device, the liquid medicine atomization device comprises a medicine storage tank, a control valve, a pump and an atomizer which are sequentially connected, and the control valve is further connected with a controller. In order to make the foot therapeutic apparatus provided by the invention suitable for atomization therapy, in the technical scheme, a liquid medicine atomization device is also fixedly arranged on the mounting frame. The atomized liquid medicine is uniformly diffused in the treatment space and contacts the wound surface of the patient in an all-around manner, and the treatment experience and the optimized feeling of the patient are improved.
Preferably, still fixed mounting has the oxygen generating equipment on being located the mounting bracket, and the oxygen generating equipment is linked together through second air flue or first air flue and treatment incasement portion including negative pressure fan, compressor and the molecular sieve that connects gradually. The oxygen can be used for preparing ozone, can also play a corresponding role in treating wound surfaces, has a better using effect particularly when being matched with a high-pressure environment, and is particularly suitable for being used in the sealing construction scheme provided by the invention.
Preferably, a heating device is mounted between the outer housing and the treatment box. The heating device can use water bath heating, electric heating or infrared heating, and is favorable for the ozone and the medicine to play a role and promoting the rapid circulation of blood when the temperature in the treatment space is proper or higher.
Preferably, the treatment box is made of transparent materials in whole or in part, and the ultraviolet sterilization equipment is fixedly arranged outside the transparent part of the treatment box.
