Disposable nasal suction universal throat nozzle

Abstract

The invention discloses a disposable nasal suction universal throat nozzle. The nozzle comprises a throat nozzle body and amist inlet interface; the throat nozzle is characterized by further comprising nasal suction nozzles shaped like the Chinese character 'zhi' and movably communicated with two mist outlet base ports on the top wall of the throat nozzle body; one of the two nasal suction nozzlesshaped like the Chinese character 'zhi' is horizontally rotated or the two nasal suction nozzles shaped like the Chinese character 'zhi' are rotated at the same time to widen or narrow the gap between two mist spray ports. The nozzle has the advantages that 1, for patients, the nozzle is suitable for the nasal nebulization inhalation therapy of the patients with wide nostril spacing and the patients with narrow nostril spacing; 2, for enterprises, troubles and multiple economic pressures caused by production and registration of various types of products are avoided; 3, for nurses, the troublecaused by firstly measuring the patient nostril spacing and then selecting an appropriate type of a nasal suction throat nozzle is avoided. The nozzle also has the advantages of simple structure, convenient operation and the like, and is suitable for disposable use in medical institutions, especially the otolaryngology, the respiratory, the pediatrics and the nasal nebulization inhalation therapyof critically ill patients.

Description

technical field [0001] The invention relates to a medical atomization inhalation mouthpiece, in particular to a disposable nasal suction general mouthpiece. Background technique [0002] For respiratory inflammation, especially nasal cavity inflammation, turbinate, nasal polyps, sinuses, nasal trauma, etc., local drug mist inhalation treatment for patients with nasal passages and nasopharyngeal erosion and inflammation after surgery and radiotherapy for nasopharyngeal carcinoma can be used. Improve the curative effect, avoid liver and kidney damage and superinfection caused by long-term oral administration, injection of antibiotics and other drugs, save medical resources and reduce the economic burden of patients. [0003] One, the patent application number is 0312 6529.4, and the publication number is CN1473 631A " one-time injection type oral and nasal dual-medicine aerosol inhalation throat nozzle " (for the technical scheme proposed by the designer of the present applica...

AI Technical Summary

Problems solved by technology

As attached to the description of the background technology figure 1 , 2 As shown, the corrugated double-mouth type spray nozzle 1 does have the function of adjusting the distance between the two nozzles, but it must be inserted into the nasal vestibule (nostril), otherwise it will bounce back. The problem is: 1. the spray nozzle suitable for adults, It is not suitable for children and infants; in other words, spray nozzles suitable for children and infants are not suitable for adults; ②When inhaled through the nostrils, some children will feel uncomfortable and cry; ③Traditional flat mouth (duck Mouth) type throat is for the mouth to contain inhalation, and it is usually to exhale through the nose when the mouth is inhaled. Mouth exhalation training, especially for critically ill patients, senile dementia and children, is more troublesome; continuous mouth inhalation and exhalation will affect the effect of nasal inhalation of drug mist; in other words, if patients, especially children, hold a nasal suction mouthpiece to How can I adjust and stabilize the proper distance between the two spray nozzles if I inhale through my own nose? ! ④Compared with the flat mouth mouthpiece, the spray nozzle of the nasal suction mouthpiece is much smaller, which will limit the overflow of the drug mist; if it is inserted into the nostril for inhalation, the mist outlet will be thinner and smaller, which is Because the spray nozzle is a tangible object, its tube wall will occupy a certain space / position

In summary, this technology still cannot meet the needs of patients for aerosol inhalation therapy.

[0005] 2. For enterprises, it is necessary to launch a variety of products to meet the needs of clinical treatment of different patients. The problems are: ① Every time a new product is produced, it must be registered with the relevant national agency, and every new medical device registered The product needs to pay a registration fee of one million yuan; in addition, it needs to go to a number of qualified medical institutions designated by the Health and Health Commission for trial supervision... The procedure is complicated; ② It is necessary to purchase a variety of production equipment; ③ It is necessary to increase production sites and workshops...

Due to the difficulties, many enterprises are discouraged, and it is difficult to convert a new technology into a new product

[0006] 3. For nurses, when giving patients nasal suction treatment, they need to measure the distance between the two nostrils of the patient first, and then choose the corresponding type of nasal suction mouthpiece, just like wearing glasses, they need to measure the interpupillary distance and optometry..., other Operation is more troublesome

[0009] 2. For adult patients, when inhaling with a mask, it is inconvenient to talk to family members, companions, visitors, and medical staff, it is inconvenient to cough, spit, and it is inconvenient to drink and eat
