Description

nasal medicine applicator

technical field

The utility model relates to a medical device, in particular to a nasal cavity drug applicator which can adjust the amount and position of drug spraying.

Background technique

General systemic medication, not only the dosage is large, but also the local effect is relatively poor, and it is easy to cause relatively large toxic and side effects. Local administration can not only make up for the defects of systemic administration, but also bring better curative effect. In recent years, intracavitary medicine has become a convenient and effective way of medicine in clinic. This kind of medicine has the advantages of directly reaching the affected area and eliminating the focus. Nasal drug applicators in the prior art usually adopt a hard structure similar to a syringe, which will rub against the sensitive mucosal epithelium in the nasal cavity during use, which may easily cause damage to the nasal mucosa or epithelium, thus bringing pain to the patient; At the same time, due to the cost problem, the medicine applicator usually needs to be used multiple times and needs to be disinfected frequently, which is not conducive to the improvement of work efficiency. In addition, the nasal drug applicator in the prior art is usually unable to adjust the position of drug administration, and there are often phenomena of uneven dispersion of drugs and waste of drugs.

Utility model content

In order to solve many problems in the prior art, the utility model provides a nasal medicine applicator, which has the advantages of less pain, easy cleaning and controllable medicine spraying.

The nasal medicine applicator is realized through the following technical scheme:

A nasal drug applicator, comprising a drug spraying section, a drug processing section and a medicine bottle; the drug spraying section includes an inner nozzle tube and a soft rubber outer tube; the soft rubber outer tube is nested outside the nozzle tube , the inner wall of the bottom of the soft rubber outer tube is provided with a groove, and the groove cooperates with the protruding ring arranged at the bottom of the inner nozzle to connect them flexibly; the soft rubber outer tube can rotate relative to the inner nozzle ; The side wall of the inner spray pipe is provided with multiple sets of vertically arranged inner medicine outlets, and the top of the inner spray pipe is provided with a top medicine outlet; The position corresponds to the outer drug outlet, the top of which is also provided with a second top drug outlet corresponding to the top drug outlet; the drug processing section includes a housing, a drug atomizing device and a drug extraction device and a power supply arranged in the housing ; The top of the drug atomization device is connected to the inner nozzle through a conduit, and the bottom is connected to the drug extraction device; the drug extraction device extracts the drug from the medicine bottle through the extraction tube, and both the drug atomization device and the drug extraction device pass through the circuit Connect to power supply.

Preferably, there are four sets of inner drug outlets, which are evenly distributed on the side wall of the inner nozzle.

Preferably, an internal thread is provided on the inner wall of the medicine bottle; it is movably connected to a flange with an external thread provided at the bottom of the housing through the internal thread.

Preferably, the drug treatment section further includes a heater arranged around the catheter.

Compared with the common nasal drug applicator in the prior art, the drug spraying section of the nasal drug applicator provided in the utility model adopts a double-layer structure, the inside of which is a hard catheter, and the outside is a soft rubber structure, which ensures The service life and strength improve the patient's comfort during use, and the direct contact between the medicine applicator and the nasal cavity will not cause discomfort; through the flexible connection between the inner layer and the outer layer, it can be used according to the position of the affected area during use. , turn the outer tube to realize the connection and closure of the inner drug outlet and the outer drug outlet. For the lesions in the shallow nasal cavity, turn the outer tube to connect the inner drug outlet and the outer drug outlet, so that the drug can be sprayed on the affected area; When the lesion is located inside, the outer tube is rotated, and the inner drug outlet is closed by the side wall of the outer tube, and the drug is concentrated at the top outlet of the drug for spraying, and the drug can be sprayed deep into the nasal cavity. In addition, through the connection of the movable inner and outer layers, the outer soft rubber outer tube can be replaced at any time, so that one person can have one tube, and there is no need to clean the medicine applicator all the time, which reduces maintenance and use costs and improves safety. . By further setting the heater, the atomized medicine can be heated to improve the comfort of the patient.
