Disposable jet formula mouth and nose two medication mists suck larynx and chew

The present invention relates to a kind of medical drugs mist suction larynx and chew, especially a kind of disposable jet formula mouth and nose two medication mists suck larynx and chew.

In mid-December, 2002, I am because of nasal mucus band blood and a little stench flavor is arranged near the Baiyun District, Guangzhou City hospital department of otorhinolaryngology (address: GuangZhou Road north, Guangzhou City the dwelling, postcode: 510500) go to a doctor, the doctor says that my nasal meatus and nasal sinuses have inflammation after checking, open some oral medicine and nose drops and given me, also allow me do nasal meatus ultrasonic atomizatio (medicine mist) simultaneously and suck one week of treatment, hold my treatment of doctor's open in person after paying dues and singly come into otorhinolaryngologic therapeutic room, the nurse takes out a duckbilled (flat chewing) type larynx and chews (manufacturer in a packaging bag; Jin Lida medical supplies factory, the address: north gate, Jin Li town, Gaoyao City, Guangdong Province, postcode: 526105, phone; 0758-8568233), the end that connects (socket) the corrugated medicine mist suction catheter on ultrasound atomizer very deftly, then the larynx that connects is chewed and passed me, and enjoin me that larynx is chewed and aim at nostril suction mist, because septonasal stopping, the nurse practitioner passs my Duckbill type larynx and chews the slotting nostril of not advancing, many medicine mists run off in vain, I hear that a head of a family who inhales the mist child is also in complaint at that time, why not give a nozzle that is fit to through the nostril suction? the nurse practitioner replies: do not sell on the market, can't buy; Because it is curious, I while inhale mist observe another ultrasonic atomizatio inhaler (name of product: 402 ultrasound atomizer. manufacturer: Siling Medical Equipment Factory, Shanghai. address: No. 1509, Luoshan, Shanghai Pudong New Area road. phone: 58333798), that is an a kind of device two pipes two ultrasonic atomizatio inhalers of chewing, connecting two corrugated medicine mist suction catheteies and two Duckbill type larynxs in other words on the aerochamber of a ultrasonic atomizatio inhaler chews to suck simultaneously for two people and smokes, connect each other, because the air force that the ultrasonic atomizatio inhaler provides is very little, chew and inhale mist the mist phenomenon is arranged back often sucking larynx, in addition because two respiratory rhythms of inhaling the mist patient are inconsistent, the mist that returns that patient spues is sucked by another patient, very easily cause medical cross infection, even if unit single tube list chew single use ultrasound atomizer (as: the WH-96 soniclizer that Guangdong Yuehua Medical Instruments Factory, Shantou City produces. the address: the Shantou City, Guangdong Province is with No. 2, beneficial road. postcode: 515031. phones: 0754-8332123 or 8276051. fax: 0754-8253513. larynx in the ordinary course of things chew or face shield is disposable use, corrugated medicine mist suction catheter is for soaking or the gas depoisoning repeated use, ultrasound atomizer is for public for a long time), its time mist also can enter in corrugated medicine mist suction catheter and the aerochamber and pollute, the danger of respiratory infectious diseases such as propagating tuberculosis and severe acute respiratory syndrome is not only arranged, and the danger of propagating infectiouss disease of the digestive tract such as hepatitis A is arranged.For this reason, I am being with make a special trip to a certain place Guangdong People's Hospital, each Affiliated Hospital of Guangzhou Zhongshan Medical Univ., each Affiliated Hospital of Traditional Chinese Medicine University Of Guangzhou, attached Nanfang Hospital of No.1 Military Medical Univ. and Guangzhou General Hospital Guangzhou Military Command of these problems to understand, and they take the larynx of the nebulizer that shows me to chew also (all) to be duckbill.The Nanning City went on business the Spring Festival in 2003, visited the nebulizer (name of product: SW-II type jetting type medical vaporizer that Guangxi Medical University first and the 3rd Affiliated Hospital use by the way, producer: triumphant the industrial products institute in state-run Liuzhou city, address: No. 202, refined scholar road, Liuzhou city. phone: 0772-2811719 or 2810259. fax: 0772-2810259, postcode: 545001), the larynx of its accessory is chewed and also is duckbill, in addition since larynx chew and can not be fixed on the disease population, but assist the critical patient to suck the suction mist by accompanying the people to grip nebulizer, not only its operation comparatively bothers, nor can inject in the nostril.Practical nursing magazine (clinical medicine core periodical, sponsored by health ministry Department of Medical Administration) has been published the technical paper of one piece of exercise question for " comparisons of 3 kinds of atomizing types " in the 10th page of the 17th the 4th phase of volume of April calendar year 2001, except that high flow capacity medicine oxygen nebulizer adopts face shield sucks, the mouth of sucking of the accessory of its Yadu nebulizer and hundred auspicious air compression atomizing inhalers equally also is duck and chews shape.February 26 in 2003, the Japanese went to Guangdong Province cardiovascular diseases hospital (Mr. Fok, Henry Ying Tung donates money to build by the vice-chairmen of the CPPCC National Committee) to visit a patient in league with several friends, the nurse gives this patient's nebulizer (manufacturer: capital, Hangzhou tinkling of pieces of jade medical apparatus and instruments company limited, factory site: Hangzhoupro, Hangzhou sea route 78-1. name of product: oxygen face mask, the application number of on 03 31st, 1999 bulletins of the architectural feature of this product and Patent Office of the People's Republic of China is that 97249561 medicine oxygen nebulizer is identical) on be not equipped with larynx and chew, replace larynx to chew suction but adopt face shield to suck, do not produce back mist though adopt face shield to suck, but this patient is in cough, spit and ceaselessly open face shield during with our greeting, cause the medicine mist to run off in vain, and the mist post does not directly spray to the nostril, basically be passive suction, by contrast, the effect of droplet adhesion nasal meatus mucosa does not have the mist post directly so good to the nasal meatus injection relatively.
