Method and apparatus for heating and applying warm antifog solution to endoscopes as well as a distal lens protector

InactiveUS20050234301A1Superior anti-fogging protectionAvoid condensationSurgeryEndoscopesElectricityEngineering
A sterile, self-contained, disposable apparatus used for heating and applying solution to the distal end of endoscopes as well as an endoscopic lens protector. The heating mechanism is chemical, electrical or a combination of both. Further the apparatus serves as a self sealing container for the storage and application of anti-fog solution. By placing the apparatus over the distal scope prior to surgery, the scope is protected from damage from other instruments or trays. At the same time the distal lens is submerged in the warm anti-fog solution and it is uniformly and completely coated. Heat is transferred to the instrument from the solution in one example to act as an important and additional measure to prevent fogging of the lens. By heating the solution and the instrument, the drastic temperature difference between the interior of the body (98.6) and the instrument is eliminated. This inhibits the condensation of moisture, which always occurs upon inserting the cool scope inside the warm body. The apparatus combines the use of an anti-fog solution as well, which helps prevent fogging during the procedure when smoke and heat is generated within the body during the procedure. Lastly, the apparatus is designed to be used as a holder of the scope while protecting it from impact with a shock absorbent outer shell prior to, during, and after the medical procedure. A new method for defogging endoscopes by which a sterile protective device is combined with a defogging mechanism and placed over the distal lens of endoscopes prior to the medical procedure, used intermittently during the procedure, then placed over the lens at the end of the procedure. The apparatus is not removed until scope reaches the cleaning facility. This apparatus is ideal for sterile operations where the instrument is used intermittently and repeatedly.

Process for preparing caprolactam

The invention discloses a process for preparing caprolactam, which comprises the following steps: after mixing cyclohexanone and cyclohexane evenly, carrying out an oxamidine reaction to obtain a cyclohexane solution of cyclohexanone oxime; enabling the cyclohexane solution of the cyclohexanone oxime and oleum to react to generate a caprolactam sulfate solution, curing the caprolactam sulfate solution, then carrying out a neutralization reaction on the cured caprolactam sulfate solution and ammonia, afterwards separating the two materials to obtain a crude product of caprolactam and then carrying out extraction and water back extraction respectively to prepare a finished product. Because of the existence of a cyclohexane inert solvent, rectification and separation do not need to be carried out after the oxamidine reaction, and only a rearrangement reaction needs to be carried out after the water phase of a catalyst is separated, thereby saving a rectification device and the steam consumption; as a result, a caprolactam enterprise with an annual yield of a hundred thousand tons can save energy worth approximately 60000000 yuan every year and can also save the one-off equipment investment totaling 60000000 yuan, the technological process of caprolactam is simplified, the procedures of water washing, extraction, distillation and the like are reduced, the production period is shortened, and the annual yield is enhanced.

Process for extracting and washing cyclohexane oxime

The invention discloses a process for extracting and washing cyclohexane oxime. The process comprises the following steps of: extracting an extractant and aqueous solution of cyclohexane oxime in a weight part ratio of 1:1 to 2:1 at the temperature of between 45 and 55 DEG C; washing an organic phase obtained by the extraction with desalted water when the mass concentration of the cyclohexane oxime is less than 1 percent so as to remove salt ions in the cyclohexane oxime solution; mixing a water phase obtained after washing and a water phase obtained by extraction, and extracting the mixture by using a cyclohexane or hexane extractant in a weight part ratio of 0.5:1 at the temperature of between 45 and 55 DEG C so as to recycle the cyclohexane oxime in the mixture; and sequentially performing hydraulic cyclone separation and gravity settling separation on the washed organic phase when the mass concentration of the salt ions in the organic phase is less than 0.0001 percent so as to obtain the cyclohexane oxime. The process does not need a rectification process; the purity of the obtained cyclohexane oxime is high; beckmann rearrangement can be directly performed in the next process so as to prepare caprolactam; and for 100,000 t/a of cyclohexanone oxime devices, the process can save one-time equipment investment by about 20 to 30 million and can reduce energy consumption such as water, electricity, steam and the like by about 30 to 40 million.
