The utility model provides the new medicine inhalator which adopts the principle of contrastream injection, and is mainly composed of a sleeve body (1), an inner sleeve (2), a bottom cover (3) and a nozzle cover (4), wherein, a medicine charging hole (5) and a medicine inhaling opening (6) are arranged on the sleeve main body (1), the inner part of the sleeve main body (1) is provided with a medicine pipe socket (9), and the bottom part is provided with a groove (10). The bottom part of the inner sleeve (2) is provided with an air flow groove (7). The utility model provides the new medicine inhalator which has the advantages of small volume, convenient carrying and safe and comfortable use.

Description

A kind of novel inhalation device

This utility model belongs to medical instruments field, is specifically related to a kind of novel inhalation device.

Current, because the influence of factors such as environmental pollution increasingly sharpens, the sickness rate of asthmatic patient is in rising trend, therefore, the Ge Lansu of domestic and international many pharmaceutical factories such as Sino-foreign joint venture-Wei Kang drugmaker, Astra Pharma Inc., Chinese Shanghai Xinyi pharmaceutical factory etc. all suck medicament in production asthma, the all mass productions of these metered dose inhalation aerosols (MDI) product have entered hospital and pharmacy.But, metered dose inhalation aerosol (MDI) product in use, the patient must hands by metered dose inhalation aerosol (MDI) cartridge case with air-breathingly carry out synchronously, otherwise medicine is detained in patient's mouth, the larynx, not only waste medicine, also will bring side effect to health, particularly child and old man have run into very big difficulty when using these metered dose inhalation aerosols (MDI) product.Therefore, existing producer begins to produce inhalation device both at home and abroad, these inhalation devices all adopt cushioning principle, their operation principle is that the medicine with metered dose inhalation aerosol is ejected in the nebulizer earlier, and then allow the patient in nebulizer, inhale medicine, so just can solve use metered dose inhalation aerosol (MDI) product must be by cartridge case and air-breathing problem of carrying out synchronously.But reach this purpose, these inhalation devices all must reach certain capacity, generally require about 500 milliliters, and asthma is a kind of chronic respiratory tract disease that needs long-term treatment, the patient often requires with medicine belt at one's side, can inhale medicine at any time,, obviously use extremely inconvenient so want the patient with a so big container.

The purpose of this utility model is exactly in order to solve the deficiency of existing like product, to provide a kind of volume small and exquisite, the novel inhalation device that result of use is good.

In order to achieve this end, this utility model provides a kind of novel inhalation device, and it mainly is made of sleeve body, inner sleeve, bottom, mouth lid; Wherein, powder charge hole, medicine inhaling mouth are arranged on the sleeve body, there is the pencil socket inside, and air drain is arranged at the bottom, and inner sleeve is positioned at the inside of sleeve body, and airslide is also arranged at its bottom.The novel inhalation device of this kind adopts the contrainjection principle, the patient must suck the medicine inhaling mouth of inhalation device before inhaling medicine, and metered dose inhalation aerosol (MDI) cartridge case has been contained in the place, powder charge hole of inhalation device, so whole inhalation device is in a closed state substantially before work.When the patient pressed metered dose inhalation aerosol (MDI) cartridge case, wherein medicine was gone out cartridge case behind the cartridge case pressurized, and the cartridge case inner sleeve that promotes inhalation device moves it backward and opens bottom simultaneously, and the air drain of sleeve body bottom is exposed in the air.At this moment, the atmospheric pressure of inhalation device outside is greater than the air pressure of inhalation device body interior, because the air of pressure reduction outside flows into main body along the air drain of inhalation device sleeve body bottom, the airslide of inner sleeve bottom, medicine in the metered dose inhalation aerosol (MDI) has been ejected in the inhalation device simultaneously, inflow along with outer gas stream, this strand air-flow medicine that not only atomized, also have one to rush at the power of medicine inhaling mouth, at this moment the patient needs only air-breathing, medicine just can be drawn onto the deep of lung, reaches ideal therapeutic effect.

Like this, the novel inhalation device that this utility model provides is owing to adopted the contrainjection principle, problem air-breathing and that must carry out synchronously by cartridge case when fundamentally having solved use metered dose inhalation aerosol (MDI), the not negative effect that can cause drug residue to bring in mouth, throat makes the safety of using strengthen greatly; And its volume also dwindles greatly, and helping user like this can carry, and uses convenient.

Below in conjunction with drawings and Examples this utility model is further described.

The novel inhalation device structural grouping figure that Fig. 1 provides for this utility model

The novel inhalation device dosing sketch map that Fig. 2 provides for this utility model

The novel inhalation device user mode reference diagram that Fig. 3 provides for this utility model

The novel inhalation device that this utility model provides mainly is made of sleeve body 1, interior cover letter 2, bottom 3, mouth lid 4 as shown in Figure 1; Wherein, powder charge hole 5, medicine inhaling mouth 6 are arranged on the sleeve body 1, air drain 10 is arranged at the bottom, and airslide 7 is arranged at the bottom of inner sleeve 2.The novel inhalation device dosing sketch map that this utility model provides as shown in Figure 2, during use, at first take off mouth lid 4, take out metered dose inhalation aerosol (MDI) cartridge case 8, and shake up medicament, metered dose inhalation aerosol (MDI) cartridge case 8 is inserted in the powder charge hole 5, be connected, determine that simultaneously the bottom 3 of medicine absorber is in closed condition with pencil socket 9.The novel inhalation device user mode reference diagram that this utility model provides as shown in Figure 3, medicine inhaling mouth 6 contained in the inlet pack tightly, begin air-breathing, and when air-breathing, press metered dose inhalation aerosol (MDI) cartridge case 8, if when feeling to have any problem, mouth can be covered 4 by on metered dose inhalation aerosol (MDI) cartridge case 8, using by metered dose inhalation aerosol (MDI) cartridge case 8.At this moment, the masterpiece of pencil is used for the pencil socket 9 in the inhalation device sleeve body 1 on metered dose inhalation aerosol (MDI) cartridge case 8, goes out the medicine outlet of metered dose inhalation aerosol (MDI) cartridge case 8 in the tube behind the medicated powder pressurized.At this moment, inner sleeve 2 is subjected to move backwards behind the impulse force, push the bottom 3 of the inhalation device of originally closing open, after inhalation device bottom 3 is open, exposed 4 air drains 10 of sleeve body bottom, made air-flow to enter in the inhalation device along the air drain 10 of sleeve body 1 bottom, the airslide 7 of inner sleeve 2 bottoms.

The novel inhalation device that this utility model provides makes asthmatic patient to carry owing to adopted a kind of new structure, use safer, comfortable, for the quality of life of improving asthmatic patient contributes.
