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] like Figure 11 As shown, the present embodiment is based on the aforementioned content, and the position of the component is optimized, and the overall is divided into a handheld portion and a wear portion.

[0094] like Figure 12 As shown, the handheld portion includes adult pharmaceutical needle top out of the mechanism 7, the drug container set mechanism 5 and the power supply 6, such as Figure 13 , 14 As shown in the wear portion, wear in the head by the corresponding wear structure, so that it can greatly reduce the weight wearing the head portion.

[0095] like Figure 15 As shown, the handheld portion and the wear portion are connected via a pipeline. Not only that, but since the power supply 6 is in the handheld part, the electric energy required to wear parts needs to be connected to the handheld part, such as Figure 16 , 17 As shown, two TYPE-C structures are used in this embodiment to achieve power supply and signal transmission.

Embodiment 2

[0097] like Figure 18 , 19 As shown, this embodiment is integrated with the handheld portion and the wear portion in the first embodiment to become a whole wear portion, although sacrifices a certain wear comfort, this integrated structure does not appear in the handheld portion and Dearing some of the risk of unexpectedly detachment, more secure. And the device integration is high, the pipeline is minimized, so that the residual liquid in the line is least.

Abstract

The invention provides a device for spraying medicine to a nasal cavity and a using method. The device comprises a medicine supply pump, a medicine feeding needle ejection mechanism, a medicine container sleeving mechanism, a medicine feeding pipe and a medicine feeding pipe feeding mechanism; an input end of the medicine supply pump is connected with the medicine feeding needle ejection mechanism through a pipeline, the medicine feeding needle ejection mechanism is provided with an ejector pin output end, and an ejector pin output end is located on one side of the medicine container sleeving mechanism; one or more medicine containers are installed in the medicine container sleeving mechanism, and the medicine containers can be pushed to positions corresponding to the ejector pin output end of the medicine inlet needle ejection mechanism; one end of the medicine feeding pipe is connected with an output end of the medicine supply pump, and the other end of the medicine feeding pipe is sealed and provided with spray holes in the side wall; and the medicine feeding pipe feeding mechanism is connected to the medicine feeding pipe and can bend, feed and withdraw the medicine feeding pipe. The device can realize atomization administration and intermittent continuous administration, and is suitable for administration of medicines such as biological medicine.

Description

Technical field [0001] The present invention relates to the field of medical equipment, and Background technique [0002] The use of medicine for treating brain disease is mainly oral and injection. Under some special circumstances, the effect of oral drugs is not good. The main reasons are: First, patients with elderly, children and some special diseases have difficulty in swallowing, or exist Obvious oral absorption barrier, such as vomiting, severe diarrhea, gastrointestinal lesions, or potential absorption disorders. Second, the treatment of brain disease requires high brain tissue concentration, but due to the liver's first effect and the presence of blood-brain barriers, oral administration is not easy to reach high concentrations in brain tissue. The third is that the disease is serious, the condition is progressing rapidly, and urgent treatment needs to be administered, and the traditional oral formal drug reaches the brain tissue time, and the effectiveness is slow. Four...
