Adjustable volatile cell for ocular surface medication

The invention provides an adjustable volatile cell for ocular surface medication. The adjustable volatile cell comprises an outer frame with a groove, shaft levers, a twisting wheel and a medicine container. The medicine container is disposed in the groove. The shaft levers are connected to two ends of the medicine container. The medicine container is rotatably connected with the outer frame through the shaft levers. One of the shaft levers is connected with the twisting wheel through the outer frame. When used, the adjustable volatile cell is worn below an eye of a patient and is closest to an eyeball, effects of volatile medicines are utilized to the maximum extent, and a novel approach is developed for eye medication. The volatile medicines are anti-inflammatory, applicable to anti-pathogenic microorganisms, and capable of eliminating asthenopia, relieving dry symptoms of eyes and eliminating xerophthalmia. An opening is arranged on only one side of a rotary wheel (a through hole is arranged on only one side of a thin film). When the adjustable volatile cell is not used, the twisting wheel is twisted to drive the rotary wheel so as to rotate the opening side into the groove, and accordingly dust is prevented from falling on a carrier for carrying medicine liquids, and the medicine liquids can be prevented from continuing to volatize.

A photoflash thermal analysis-delayed purge injection method for the detection of drug mixtures

The invention discloses a light flash thermal analysis-delay purging sample introduction method for rapid and simultaneous detection of volatile and low-volatile drug mixtures. There are many types of drugs with large differences in structure and molecular weight, and some of them are difficult to volatile drugs. They will reduce the sensitivity of drug detection instruments that use thermal analysis to inject samples, and at the same time affect the detection and identification efficiency of opium or new psychoactive drug mixtures. The present invention solves the problem of rapid and simultaneous detection of volatile-refractory drug mixtures. The analysis method uses a halogen lamp to perform "flash heat" to rapidly heat up the drug mixture and increase the vapor pressure of the mixed sample, thereby increasing the atmospheric pressure. The ionization efficiency increases the signal intensity of less volatile samples in the mixture by more than an order of magnitude. Combined with the time-delay purging device, the difficult-to-volatile and volatile substances volatilized during the flash heat are purged into the ionization chamber at the same time, which reduces the loss of samples during the continuous purging and heating process, and realizes the difficult-to-volatile and volatile substances. Simultaneous detection of both.

A kind of veterinary pefloxacin mesylate pellets and preparation method thereof

The invention relates to animal pefloxacin mesylate pellets, and a preparation method thereof. The preparation method of the animal pefloxacin mesylate pellets comprises steps that: pefloxacin mesylate powder, a wall material which is a high-molecular material, and cyclohexane are placed in an organic solvent reaction vessel, and reflux is carried out for 1 to 2 hours under a temperature of 80 to85 DEG C; the temperature of the materials is reduced to 25 to 35 DEG C at a speed of 1 to 3 DEG C per 5 minutes, such that pefloxacin mesylate is coated with the wall, and pellets with sizes of 40 to 200 meshes are formed; the pellets are vacuum-dried, such that the animal pefloxacin mesylate pellets are obtained. According to the animal pefloxacin mesylate pellets provided by the invention, a high-molecular material or polymer is coated on the surface of the medicine, such that tiny sealed capsules are obtained, and the capsules serve as covers or protective films. Therefore, the bitter taste of the medicine can be covered; medicine stability can be improved; and volatilization of volatile medicines can be controlled. The animal pefloxacin mesylate pellets provided by the invention has advantages of convenient use, simple production technology, low cost, high medicine bioavailability, low irritation to intestines and stomach, and good medicine stability.

Light flash thermal desorption-delayed purging sample injection method for drug mixture detection

The invention discloses a light flash thermal desorption-delayed purging sample injection method for rapidly and simultaneously detecting volatile and non-volatile drug mixtures. A plurality of typesof drugs exist, and are large in difference of the structures and the molecular weights; and some drugs, which are not easy to volatilize, can reduce the sensitivity of a drug detection instrument utilizing thermal desorption sample injection, and meanwhile, influence the detection and identification efficiency of opium or new psychologically active drug mixtures. According to the method, the problem of rapid and simultaneous detection of the volatile-non-volatile drug mixture is solved; a halogen lamp is used for flash heating, so that the drug mixture is rapidly heated, the vapor pressure ofthe mixed sample is increased, the ionization efficiency at normal pressure is improved, and the signal intensity of the non-volatile sample in the mixture is improved by one order of magnitude or more; and by combining with a delayed purging device, the non-volatile and volatile substances volatilized during flash heating are purged into an ionization cavity at the same time, so that the loss ofsamples in the continuous purging and heating process is reduced, and the simultaneous detection of non-volatile and volatile drugs is realized.
