Problems solved by technology

This design not only wastes a lot of liquid medicine and has poor curative effect, but also causes difficulty in medication for patients with neck diseases.
[0004] The nozzle of the median nozzle nasal spray is mostly a single-hole straight design, and the drug is sprayed in a scattered manner when spraying. Although the drug can be sent into the nasal cavity far away with the help of the spray force, it is necessary to act on the middle turbinate and middle nasal passage. For patients with important structures such as the lateral wall of the nasal cavity, the spraying effect is not good
[0005] Most of the medicinal liquid used for nasal irrigation with the median nozzle rushes to the posterior nostril, flows back to the oropharynx and oral cavity, or flows out from the anterior nostril, and less liquid enters the middle nasal passage on the lateral wall of the nasal cavity. For some sinusitis For patients who have undergone sinus endoscopic sinus surgery with open sinuses, the poor irrigation effect of the middle nasal passage directly affects the healing of the disease and postoperative recovery

Embodiment 1

[0025] refer to Figure 1 to Figure 6 , the present embodiment is made up of nozzle 1 and medicine bottle 2, medicine bottle 2 is fixed below nozzle 1, nozzle 1 is arranged on the top of nozzle 1, and connecting pipe 4 is fixed inside nozzle 1.

[0026] The nozzle 1 is tapered with a smooth top, and its shell 1-1 is made of solid material, which is convenient for cleaning. The nozzle 1 has a certain length, which allows the nozzle 1-2 to penetrate into the nasal cavity, shortens the distance between the nozzle 1-2 and important anatomical structures such as the middle nasal passage, and facilitates the contact of more liquid medicine with the mucous membrane.

[0027] There are twelve nozzles 1-2, the outlets of all the nozzles 1-2 are arranged on the top edge of the nozzle 1, and all the nozzles 1-2 are arranged vertically close to the inner wall of the housing 1-1 of the nozzle 1. All the nozzles 1-2 are placed obliquely close to the inner wall of the housing 1-1, so that t...

Embodiment 2

[0033] refer to Figure 5 to Figure 10 , the present embodiment also has shower head 1 and medicine bottle 2, and the upper end of connecting pipe 4 also communicates with all nozzles 1-2. What differs from embodiment 1 is that medicine bottle 2 adopts the hard material of quality to make, and its bottle body 2-1 and bottleneck 2-2 are all ellipsoidal cylinders, and bottleneck 2-3 is cylinder; Medicine bottle 2 is fixed with Press pump 6.

[0034] In order to keep the pressure stable during use and avoid shaking of the nozzle 1, preferably, an elliptical cylindrical cap 1-3 with a downward opening is connected under the nozzle 1, and the cap 1-3 is slightly larger than the bottle neck 2-2 , to be convenient to cover cap 1-3 to be inserted into bottleneck 2-2.

[0035] There are two opposite use marks 3 on both ends of the upper surface of the cap 1-3. When looking down on the side-mounted nozzle nasal spray, the outlet ends of all the nozzles 1-2 are arranged in an arc shape...

Abstract

The invention relates to the technical field of medical apparatuses, in particular to a nose spray device with side-arrangement-type spray nozzles. The nose spray device with side-arrangement-type nozzles comprises a spray head and a medicine bottle, wherein the medicine bottle is fixedly arranged below the spray head; spray nozzles are arranged at the top end of the spray head; a connecting tube is arranged in the spray head, the number of the spray nozzles is more than two, outlet ends of the spray nozzles are formed on one side of the edge of the top of the spray head and the spray nozzles are vertically arranged in contact with the inner wall of the shell of the spray head; an inclined refraction surface which is used for controlling the spray angle is arranged on the inner wall of the outlet end of each spray nozzle; the upper end of the connecting tube is communicated with the spray nozzles; the nose spray device with the side-arrangement-type spray nozzles is provided with at least one use identifier. The nose spray device with the side-arrangement-type spray nozzles has the advantages that the structure is simple and reasonable, the nose spray device is simple and convenient to operate and the liquid medicine utilization ratio is high, and is suitable for human body nasal cavity disease treatment.

Description

technical field [0001] The invention relates to a medical device, in particular to a nasal drug delivery device. Background technique [0002] At present, in the medical industry, the lateral wall of the nasal cavity including the middle meatus is the key recovery area after sinusitis and sinus endoscopic surgery, and the functional recovery of this area directly affects the overall treatment effect. For the layout of nasal diseases, the median nozzle nasal dropper, the median nozzle nasal spray and the median nozzle nasal irrigator are generally used. [0003] The neutral nozzle nasal dropper allows the patient to lean back and use gravity to drip the medicine into the patient's nasal cavity, and most of the medicine dripped into the nasal cavity flows directly to the nasopharynx along the bottom of the nose. To the oropharynx and oral cavity and forced to bear the strange taste of the drug. This design not only wastes a lot of liquid medicine, but also has poor curative ...
