Problems solved by technology

[0002] The traditional medication methods for treating brain diseases are mainly oral and injection. In some special cases, the effect of oral medication is not good. Significant oral malabsorption, such as vomiting, severe diarrhea, gastrointestinal lesions, or potential malabsorption
Second, the treatment of brain diseases requires a very high drug concentration in brain tissue, and due to the first-pass effect of the liver and the existence of the blood-brain barrier, it is difficult to achieve a high concentration in the brain tissue by oral administration.
The third is that the disease is serious and the disease progresses rapidly, and emergency treatment is required, while the traditional oral method takes a long time for the drug to reach the brain tissue, and the onset of effect is slow
Fourth, when the patient's compliance with oral treatment is poor
This device is too simple to achieve nebulized administration and intermittent continuous administration, so it cannot be applied to the administration of drugs such as antipsychotics

Embodiment 1

[0093] Such as Figure 11 As shown, this embodiment optimizes the position of the components on the basis of the foregoing, and divides the whole into a handheld part and a wearing part.

[0094] Such as Figure 12 As shown, the hand-held part includes a drug injection needle ejection mechanism 7, a drug container set mechanism 5 and a power supply 6, such as Figure 13 , 14 Shown is the wearing part, which is worn on the head through a corresponding wearing structure, which can greatly reduce the weight of the wearing part on the head.

[0095] Such as Figure 15 As shown, the hand-held part and the wearing part are connected by tubing. Not only that, because the power supply 6 is located at the hand-held part, the required electric energy of the wearing part needs to be connected with the hand-held part by lines, such as Figure 16 , 17 As shown, in this embodiment, the Type-C structure is used to connect the two, so as to realize power supply and signal transmission. ...

Embodiment 2

[0097] Such as Figure 18 , 19 As shown, this embodiment integrates the handheld part and the wearing part in Embodiment 1 into an integral wearing part. Although a certain degree of wearing comfort is sacrificed, this integrated structure does not have the handheld part and the wearing part. The risk of accidental detachment of the wearing part is more secure. Moreover, the device has a high degree of integration, the pipeline is minimized, and the residual liquid in the pipeline is minimized.

Abstract

The invention provides a device for spraying medicine into the nasal cavity and its use method, comprising: a medicine supply pump, a medicine feeding needle ejection mechanism, a medicine container set mechanism, a medicine feeding tube and a medicine feeding tube feeding mechanism; The input end is connected to the injection needle ejection mechanism through a pipeline. The injection needle ejection mechanism has a thimble output end, and the thimble output end is located on one side of the drug container set mechanism; one or more drug containers are installed in the drug container set mechanism. The drug container can be pushed to the position corresponding to the output end of the thimble of the drug feeding needle ejection mechanism; one end of the drug feeding tube is connected to the output end of the drug supply pump, and the end of the other end is sealed and the side wall is provided with a spray hole; the feeding drug The tube feeding mechanism is connected on the feeding tube, and can bend, feed and retract the feeding tube. The invention can realize atomized administration and intermittent continuous administration, and is suitable for the administration of drugs such as biomedicine.

Description

technical field [0001] The present invention relates to the field of medical equipment, in particular to a device and method for spraying medicine into the nasal cavity, in particular to a device and method for spraying medicine in a targeted manner in the upper nasal passage. Background technique [0002] The traditional medication methods for treating brain diseases are mainly oral and injection. In some special cases, the effect of oral medication is not good. Significant oral malabsorption, such as vomiting, severe diarrhea, gastrointestinal lesions, or potential malabsorption. Second, the treatment of brain diseases requires a high drug concentration in the brain tissue, and due to the first-pass effect of the liver and the existence of the blood-brain barrier, it is difficult to achieve a high concentration in the brain tissue by oral administration. The third is that the disease is serious and the disease progresses rapidly, requiring emergency treatment, while the t...
