5results about How to "Avoid foreign body sensation" patented technology

The utility model provides a kind of automobile seat cushion exhaust deodorization device, it is related to automobile seat technical field, and it includes: air-permeable piece is set on seat body, air-permeable piece is connected with exhaust pipe, exhaust pipe is connected with the air pump of setting in cockpit outside;Gas detection component is set in detection bin, and detection bin is connected through buckle detection bin cover on detection bin;By setting air pump outside cockpit, by pipeline and air-permeable piece intercommunication, avoid the embarrassment caused by sudden start and noise of exhaust fan in prior art in cab;Sensor is set in specially designed detection bin, which provides great convenience for sensor detection and maintenance;Through the gas detection component configured in seat body, gas detection component is set in detection bin, and detection bin cover is set as grid structure, so setting, can perceive peculiar smell gas before peculiar smell gas diffuses, in time utilize air pump to discharge peculiar smell gas through exhaust pipe, ensure the comfort of in-vehicle environment.

The utility model relates to a wig with a hidden label, which comprises wig pieces and the label, a plurality of wig pieces are sequentially arranged along the thickness direction, two adjacent wig pieces are fixedly connected, and the label is completely positioned between the two adjacent wig pieces. The identification on the label records product information, so that the problem that the product information is difficult to trace after an existing wig product is worn is solved; the label is located between the wig pieces, the wig pieces shield the label, the label is prevented from being observed, and the invisible effect of the wig pieces is improved; the wig piece prevents the label from being in contact with a user, foreign body sensation caused by the label is avoided, and the label cannot cause reduction of wearing comfort; according to the wig piece, friction between the label and a user is avoided, label abrasion is reduced, and identification of the label is protected.

The utility model provides a kind of ureteral stent, in the ureteral stent, the first drainage hole is equipped on the pipe wall of ureteral stent pipe;The anti-sliding stent pipe is arranged at the first end of the ureteral stent pipe, the second drainage hole is equipped on the anti-sliding stent pipe;The anti-reflux membrane is arranged at the second end of the ureteral stent pipe, the positioning ball is arranged on the part of the ureteral stent pipe close to the anti-reflux membrane, for the anti-reflux membrane is positioned.The ureteral stent in the utility model is compared with the existing ureteral stent, and the structure design is ingenious to increase function, has anti-reflux design and the design of anti-reflux is positioned, when using, the tail of ureteral stent, i.e. the second end of ureteral stent will not be vertical in bladder, avoid to cause irritation to patient bladder neck, patient has foreign body sensation condition to occur, improve equipment use comfort, satisfy patient use demand.

The invention discloses a medical flushing glue solution and a preparation method thereof, and relates to the technical field of flushing glue solutions, and the medical flushing glue solution is prepared by adding 0.15% by weight of sodium methyl cellulose, 0.8% by weight of sodium chloride and 99.05% by weight of medical purified water. According to the application, the content ratio of sodium carboxymethyl cellulose to sodium chloride is accurately matched with the requirement of a medical flushing scene, and meanwhile, the dosage of sodium carboxymethyl cellulose can enable the glue solution to have good flowability and moderate tissue adhesiveness, so that smooth flushing in clinical operation can be realized, a continuous moist protective layer can be formed on the surface of tissue, and the medical flushing effect is improved. The cleaning and protecting effects are effectively achieved; the dosage of sodium chloride can accurately simulate physiological osmotic pressure to ensure that the glue solution is compatible with the human tissue environment, in addition, the glue solution under the formula is excellent in stability, has no layering and precipitation phenomena within 6 months under the storage condition of 4 DEG C, and can meet the stability requirements of long-term storage and clinical use.

The invention discloses a stable low-viscosity budesonide nasal spray and a preparation method thereof, and relates to the technical field of pharmaceutical preparations, the stable low-viscosity budesonide nasal spray comprises the following raw materials by weight: 0.062-0.130 part of budesonide, 1.0-2.5 parts of a suspending aid, 4.0-5.0 parts of an osmotic pressure regulator, 0.016-0.048 part of a surfactant, 0.001-0.05 part of a stabilizer, 0.10-0.15 part of a bacteriostatic agent, 0.001-5 parts of a pH regulator, and 5-100 parts of purified water; according to the budesonide nasal spray, specific metal elements or metal ions are introduced into the raw materials, so that the total impurity content in the budesonide nasal spray can be remarkably reduced under the condition of not adopting a nitrogen charging and dissolved oxygen removing process, and the chemical stability and the medication safety of the preparation are remarkably improved; by adopting a heat dispersion suspending aid process, the viscosity of the liquid medicine is less than or equal to 20mPa. S and is obviously lower than that of a normal-temperature dispersion preparation process, and fog drops are finer during spraying.
