Manual double-spray-head nasal cavity drug administration quantitative and adjustable aerosol pump

Abstract

The invention discloses a manual double-spray-head nasal cavity drug administration quantitative and adjustable aerosol pump. The manual double-spray-head nasal cavity drug administration quantitativeand adjustable aerosol pump is designed special for a drug liquid product subjected to drug administration through the nasal cavity and absorbed by the nasal mucosa and belongs to an aerosol drug administration appliance universally used for a nasal cavity drug administration product. The manual aerosol pump and a dug bottle are in integrated matched design; the drug administration quantity is quantitative and adjustable according to the heights and weights of patients; the pump is operated by one key to be automatically started for drug suction; an aerosol medicament can be sprayed out through extrusion operation of two fingers, namely the thumb and the index finger; the spacing between double spray heads is adjustable at will according to the characteristics of the nose, so that the pump is suitable for all the patients; the horizontal angles of the spray heads can be finely adjusted within 90 degrees bidirectionally; and after drug administration operation is completed, the appliance automatically enters into a locked state. The manual aerosol pump is a recycled drug administration appliance and is suitable for relevant medical products of all manufacturers and each patient. 10ml, 15 ml, 20 ml and 30 ml of matched drug storing containers are optional.

Description

technical field [0001] The utility model relates to a manual aerosol pump with adjustable dosage for nasal administration with double nozzles, which is a special equipment for nasal aerosol administration and belongs to miniature medical equipment. Background technique [0002] There are four traditional ways of entering medicine in the medical field, namely: external use, oral administration, intramuscular injection, and intravenous drip. In recent years, with the rapid development of medical science, many developed countries such as the United States, Germany, and Japan have studied a new way of drug administration, which is to administer through nasal aerosol, absorb through nasal mucosa, and administer less dosage. It has the characteristics of little harm to the human body, no pain and no damage, simple operation method and reliable technical performance. Once the product came out, it was welcomed and accepted by the general public. At the same time, it also formed a l...
