Background
In recent years, the incidence rate of respiratory diseases is continuously increased, and the health and life quality of people are seriously affected, but at present, the traditional administration modes aiming at the respiratory diseases in the medical industry are oral administration, injection administration and disposable mucous membrane administration, and the injection administration comprises intramuscular injection and intravenous injection. The oral administration is convenient, but when the oral administration is carried out, the medicine mostly penetrates through gastrointestinal mucous membrane to enter blood in a diffusion mode, and the medicine acts along with the blood flowing to reach corresponding parts, so that the medicine reaches the lesion part, not only needs one process, but also is easily influenced by various enzymes and pH value of the gastrointestinal tract, and the absorption of small intestine is incomplete, so that the medicine effect is delayed and reduced. Therefore, it is sometimes difficult to achieve effective therapeutic purposes with oral administration. The injection administration is that the medicine slowly enters the blood from the muscle layer, and the medicine is absorbed more quickly at the position with richer blood vessels, so the medicine is absorbed more quickly than the oral administration. However, injection administration has a larger side effect than oral administration, such as being liable to cause tissue damage, local pain, potential complications, rapid occurrence of adverse reactions, and the like. Although the disposable mucous membrane administration can reach the effect of quick effect through nasal mucous membrane absorption by-passing brain blood barrier, the current nasal mucous membrane administration form is almost realized by adopting an invasive spray, the administration medicine effect duration of the form is shorter, and other risks can be caused by the invasive administration form.

The specific implementation process and principle description:
the flexible administration bracket body 1 is a flexible material molding bracket structure such as silicone rubber, has certain flexible deformation and stretching characteristics, meets the wearing requirement of being elastically adapted to the face of a human body, and the hood wall 4 on the hood cover body 2 can form a breathing cavity 41 for covering the oral cavity and the nasal cavity.
Referring to fig. 3 and 4, the flexible drug delivery support body 1 can meet the fixed wearing requirement in the stretched state of the wearing body 3, and when wearing, the alignment attaching part 5 can form a drug core mechanism 7 to be carried through the skin attaching and holding elastomer 6, the drug core mechanism 7 meets the direct skin attaching requirement, and meanwhile the skin attaching and holding elastomer 6 can realize stable pressure connection and elastic adjustment, so that the reliable stability of skin attaching and the comfort requirement of skin attaching are met.
The drug core mechanism 7 is provided with a skin-applied drug body including solid, liquid, etc., which is provided with stable transdermal drug delivery and volatile oral/nasal inhalation drug delivery in the respiratory chamber 41 when worn, and thus is comfortable to wear and stable in skin-applied drug delivery and volatile drug delivery. Because the hood wall 4 with a plurality of ventilation channels 42 exists, a mask can be mounted outside the hood wall 4 to carry out air intake filtration, and the use effect is better.
The wearing body 3 is described, and can adopt an ear hanging structure, an elastic binding rope structure, a magic buckle binding rope structure, a buckle binding rope structure and the like, so that the structure for fixing the flexible drug delivery bracket body 1 and the head is within the protection range of the scheme.
For the skin-contacting and holding elastic body 6, the skin-contacting and holding elastic body 6 is generally an elastic structure having an elastic deformation function, and an elastic air bag, an elastic wall surface carried by at least one elastic body, or the like can be used, and the elastic body is generally an elastic column or a spring body.
In a specific embodiment, referring to fig. 1 to 7, the wearing body 3 includes two ear hanging parts 31 disposed opposite to each other, and the ear hanging parts 31 include an ear hanging rope 32, and a threading and guiding matching structure 8 for adapting and matching with the external mask hanging rope 100 to carry out the flexible administration of the stent body and wearing the external mask relatively fixedly.
Specifically, the flexible administration bracket body 1 is used independently or in combination with an external mask, the independent use state is shown in fig. 4, and the combined use state is shown in fig. 7.
The bulge cover wall 4 of the flexible drug delivery bracket body 1 is provided with a plurality of ventilation channels 42, the air inlet supply requirement of the breathing cavity 41 is met through the ventilation channels 42, when the flexible drug delivery bracket body is combined with an external mask, the ear hanging part 31 of the flexible drug delivery bracket body is generally used with the hanging rope 100 of the mask, the wearing comfort of two hanging ropes is poor, and wearing fatigue is easy to cause.
To this condition, this embodiment has adopted the design of wearing to draw cooperation structure 8, can realize the wearing of outside gauze mask string rope 100 through this wearing to draw cooperation structure 8 and draw cooperation structure 8 to wear after wearing to draw at outside gauze mask string rope 100 along this and draw the relative positioning of flexible support body 1 and outside gauze mask to combine, only need wear outside gauze mask string rope 100 and can satisfy flexible support body 1 and wearing with outside gauze mask, and wear comparatively reliably stable.
In one embodiment, the threading engagement structure 8 includes a slit provided on the ear-hanging portion for the external mask hanging rope to pass through, and the two ropes of the external mask hanging rope are separated at intervals within the slit.
The threading and guiding matching structure 8 is mainly used for realizing the combination of the flexible drug delivery bracket body 1 and the mask after the external mask hanging rope 100 penetrates, and simultaneously meets the wearing requirement after two ends are led out.
In this embodiment, the design of the gap is adopted, and the gap can realize that two rope bodies of the single-side external mask hanging rope 100 are separated at intervals, so that two rope bodies at intervals are respectively worn and separated and limited through two ends of the gap, the external mask hanging rope can be fully separated and unfolded when being worn, wearing comfort and relative combination positioning effect are better, reliable attachment of the exposed surface of the external mask and the raised mask wall 4 can be realized, and physical barrier property to the ventilation channel 42 is better.
In one embodiment, the ear hook 31 includes two ear hook ribs 33 spaced apart from each other, and the ear hook rope is a flexible shaped ear hook rope disposed between the two ear hook ribs 33, and the flexible shaped ear hook rope has a shaped state as shown in fig. 1 and 2 and an ear hook state that is stretched and deformed as shown in fig. 3.
When the flexible shaping ear hanging rope is in a shaping state, a gap is formed between the flexible shaping ear hanging rope and the two ear hanging ribs.
Specifically, the ear hanging rib 33 is used for forming fixing parts at two ends of the slit, and in the shaping state of the flexible shaping ear hanging rope, the ear hanging rib can naturally form the slit, so as to meet the wearing requirement of the external mask hanging rope 100 in a threading and matching manner. When the flexible shaping earhook rope is used by itself, the earhook can be formed under the stretching deformation of the flexible shaping earhook rope, so that the design is that when the flexible drug delivery bracket body 1 is combined with a mask for wearing, the situation that the earhook independent of the flexible drug delivery bracket body is exposed and the like can not occur, the use is more attractive, meanwhile, the uncomfortable feeling of the concealed earhook rope for attractive appearance can not occur, and the formation of a gap is also more reliable and stable.
The characteristics and the structure of the flexible shaping ear-hanging rope are described, and the flexible shaping ear-hanging rope is a bending shaping structure in injection molding, and is in a bending shaping state in a natural state, and a stretching elastic rope body is formed only under stretching external force.
