Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of medical apparatus and instruments, and particularly relates to a disposable turbine protection sleeve for dental use. BACKGROUND

[0002] High-speed and low-speed dental turbines are the most frequently used power-driven instruments in dental clinics and are also one of the most severely contaminated instruments. They play a crucial role in the cutting, preparation, and finishing of teeth. A high-speed turbine consists of a head (including an air turbine bearing), a handle (the body part), and a tail. The head is the core part of the entire instrument and contains a turbine chamber inside which a rotor (the machine core) is located. The rotor has a transmission shaft and a transmission member composed of multiple turbine blades.

[0003] The lumen of high-speed and low-speed dental turbines is relatively narrow, with small and dense pores. In addition, during operation, it is impossible to avoid the back-suction of debris, and the air-pumping process after operation cannot be performed. As a result, the wear rate of the internal bearing is greatly increased. In order to thoroughly clean the residual debris inside the lumen and maintain the internal bearing of the machine, according to the Technical Operation Specification for Sterilization and Disinfection of Dental Instruments, the high-speed and low-speed turbines after use need to be pre-processed (pipe flushing and surface wiping) at the chair, recovered, cleaned, dried, inspected, maintained, dried again, and then packaged and sterilized after the surface is wiped.

[0004] The oiling and maintenance process is particularly important. Oiling and maintenance can effectively reduce the wear of turbine bearings, avoid increased friction and component wear due to oil deficiency, thereby protecting the precision components of dental turbines and prolonging their service life. At the same time, through oiling and maintenance, the stability and reliability of dental turbines during high-speed operation can be ensured, work efficiency can be improved, equipment failures caused by improper maintenance can be reduced, and the smooth progress of treatment can be ensured. In addition, correct oiling and maintenance can also avoid the inconvenience and risks to patients caused by equipment failure and protect the health of patients.

[0005] During the oiling and maintenance of turbines, oil packs are one of the main problems that lead to unqualified sterilization. The reasons include the following aspects: (1) uneven turbine oiling: due to the different strengths of operators, the amount of oil sprayed into the air inlet is not the same, resulting in residual oil flowing out and wetting the packaging bag after sterilization; (2) improper drying method: different drying methods have an impact on the occurrence rate of oil packs. The oil pack rate of the ordinary drying cabinet drying group is lower than that of the vertical standing group and the negative pressure vacuum drying group; (3) oil immersion before packaging: the paper-plastic packaging bag was immersed in oil before packaging and was not discovered in time; (4) oil immersion before packaging: the paper-plastic packaging bag was immersed in oil before packaging and was not discovered in time; (5) turbine not completely dried: the turbine was not completely dried after cleaning, which led to the failure of completely removing the oil.

[0006] According to the use standard of sterile articles, the package should be free of breakage, contamination and oil stains. The oil stains on the sterilization package can directly affect the sterilization effect and increase the risk of infection. Therefore, the following measures are taken: (1) Ensure uniform manual oil injection: the operator should keep the oil injection force consistent to ensure uniform oil injection amount each time; (2) Select appropriate drying method: use a common drying cabinet for drying to reduce the oil package rate; (3) Check the packaging material: ensure that the paper-plastic packaging bag is dry and free of oil stains before packaging; (4) Improve steam quality: ensure that the steam reaches the saturated state to reduce moisture and impurities; (5) Inject oil after complete drying: ensure that the turbine is completely dried before oiling for maintenance; (6) Adjust the pressure of the automatic oil injection machine: reduce the possibility of back-splashing of lubricating oil. To ensure sterilization qualification, the specific solution at this stage is to blow dry the turbine cavity with an air gun after oiling, and wipe off the excess oil on the surface with clean gauze. This step is repeated until there is no oil stain in the lumen. Some institutions also pad paper under the oil outlet hole of the machine body to achieve oil absorption function, but due to the different specific gravity of water and oil, and the saturation of paperboard in the sterilization process, the thickness of the paperboard affects the sterilization effect. This method not only consumes a lot of time, but also wastes cost.

[0007] In addition, the outer material of the turbine head is mostly titanium alloy, but due to considerations of weight and cost, the thickness of the outer shell is limited. The alloy thickness cannot resist a large external impact, and once the turbine head is deformed by impact, the entire instrument will not work normally. These are the main problems of high-speed and low-speed turbines in daily work. Practical new type content

[0010] Further, the protective sleeve body comprises a first half sleeve body and a second half sleeve body, and the first half sleeve body and the second half sleeve body are integrally formed to form a cavity body for wrapping the protection area of the dental turbine.

[0011] Further, the sterilization indicator card is arranged on the side of the first half sleeve body and / or the second half sleeve body of the protective sleeve body.

DETAILED DESCRIPTION

[0031] The implementation of the utility model will be described in detail in combination with the implementation cases, but they do not constitute the limitation of the utility model, but only serve as examples. Meanwhile, the advantages of the utility model will become clearer and easier to understand through the description.

[0032] As Figures 1-3 shown, the disposable turbine protection sleeve for dental machine of the embodiment comprises a protection sleeve body 1, one end of the protection sleeve body 1 has an opening, and the other end is a closed end; an elastic mouth sleeve 2 is arranged at the opening of the protection sleeve body 1, the elastic mouth sleeve 2 can be opened under the action of external force, sleeved on the protection area (such as the head or the base) of the dental turbine and tightly attached to the protection area under the action of the elastic recovery force of the elastic mouth sleeve 2; a sterilization indication card 3 is arranged on the side surface of the protection sleeve body 1.

[0033] As Figure 4As shown, the protective sleeve body 1 is composed of the permeation layer 4, the oil absorption layer 5 and the substrate layer 6 from inside to outside. The permeation layer 4 is a layered structure made of cotton material, and the permeation layer 4 has a plurality of permeation holes 41. The cotton material has strong permeation function, and the surface can be designed with fine embossed patterns, which helps to quickly absorb and distribute the exosmosis water and oil. The oil absorption layer 5 is a layered structure made of oil absorption cotton. The middle layer is an oil absorption layer, and the material is selected as polypropylene PP as the material of the oil absorption cotton; the oil absorption cotton is a kind of fiber and non-woven fabric made of inert polypropylene melt-blown and treated specially, which can effectively absorb and retain liquid and has strong adsorption, thereby absorbing the leakage liquid to the oil absorption cotton and effectively preventing the spread of leakage. The advantages of this material are flame retardant, no dust, no storage time limit, etc. After dehydration and deoiling treatment, the oil absorption cotton only absorbs oil and does not absorb water, so that it can absorb and lock oil without affecting the evaporation and drying of water during the autoclaving process. The substrate layer 6 is a layered structure made of crepe paper. The outer layer material is crepe paper, which plays an important role in the high-pressure steam sterilization process. The medical crepe paper is usually made of 100% pure wood pulp, which has a special porous arrangement. This structure allows sterilization media such as high-pressure steam and ethylene oxide to penetrate into the package, ensuring sterilization effect. Good antibacterial effect: crepe paper has excellent antibacterial effect, which can effectively prevent the passage of bacteria and other microorganisms, and ensure the sterile state of the packaged items. Strong adaptability: crepe paper is suitable for various sterilization methods, including pressure steam sterilization and ethylene oxide sterilization. The protective sleeve body is composed of the above permeation layer, oil absorption layer and substrate layer, which has the common characteristics of high temperature resistance and strong air permeability, and the superposition design also better ensures the safety of the turbine in the packaging bag.

[0034] The protective sleeve body 1 includes a first half sleeve body 11 and a second half sleeve body 12, and the first half sleeve body 11 and the second half sleeve body 12 are integrally formed to form a cavity body for wrapping the protection area of the dental turbine. The sterilization indicator card 3 is arranged on the side surface of the first half sleeve body 11 and / or the second half sleeve body 12 of the protective sleeve body 1. The size of the protective sleeve body 1 gradually increases and then decreases from the closed end to the opening direction of the other end. The length of the protective sleeve body 1 is 50-60mm, and the width of the widest part of the protective sleeve body 1 is 40-50mm. The oil-proof protective sleeve of the utility model is a disposable medical consumable, and the size is designed according to the corresponding instrument protection area, which is flexible and has a wider application range.

[0035] The elastic bundle port sleeve 2 is an annular pleated structure made of elastic material, and the width of the elastic bundle port sleeve 2 is 10mm-40mm. The elastic bundle port sleeve can be made of a rubber ring made of butadiene rubber, which is fixed at the opening of the entire protective sleeve. The butadiene rubber can withstand high temperature below 150℃, which meets the high temperature and high pressure conditions. The design of the elastic bundle port sleeve can not only increase the range of usable instruments, but also fix them well in the packaging bag.

[0036] The sterilization indicator card 3 comprises a substrate layer 31 coated with a color-changing ink layer 32, and the substrate layer is a layered structure made of crepe paper. The sterilization indicator card can use the outermost crepe paper of the protective sleeve as the substrate layer, and coat the color-changing ink as the sterilization indicator. The color-changing ink layer is mixed with the solution of the acid-base indicator and the pigment. When the acidity or alkalinity of the liquid changes, the color of the indicator also changes, thereby causing the color of the ink to change. The color-changing principle of the sterilization indicator card is that the indicator in the indicator card reacts with the acid-base substances in the culture medium during the high-pressure steam sterilization process, and the color changes. When the acid-base substances in the culture medium react with the indicator, the indicator changes color, thereby reflecting the pH value of the culture medium. The acid-base indicator can be bromocresol purple or bromophenol blue. These indicators are yellow when the pH value is acidic, and purple when the pH value is alkaline. Therefore, when the steam in the sterilization process transfers the acid-base substances in the culture medium to the indicator card, the indicator card changes color, thereby determining whether the sterilization process meets the requirements. The length of the sterilization indicator card is determined according to the actual situation, and the design length of the indicator card is ≤60mm, and the width is designed to be ≤40mm. The sterilization indicator card can also select commercially available sterilization indicator card products, such as the SHINVA sterilization indicator card, which has a size of 22mmx50mm.

[0037] The use method of the disposable dental turbine oil-blocking protective sleeve of the utility model is as follows: the turbine is recycled, cleaned, dried, inspected, maintained, dried again, and directly sleeved into the oil-blocking protective sleeve after wiping the surface, the turbine head 7 is placed on the closed end of the oil-blocking protective sleeve, tightly fitted, and then sleeved into a sterilization packaging bag for sealing and sterilization. Figure 5

[0038] The disposable dental turbine oil-blocking protective sleeve of the utility model has simple structure, safe material selection, non-toxic, low cost, flexible and wide application range, greatly shortened operation time before sterilization packaging, can meet the urgent needs of the oral medical field, has strong special promotion, and can achieve good market price return rate.

[0039] The above is only a specific embodiment of the utility model, and it should be pointed out that any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the utility model, which should be covered by the protection range of the utility model, and the remaining unexplained is prior art.​
