Technical Field

The invention relates to the technical field of treatment devices in the department of respiration, in particular to a clinical inhalation type drug delivery device in the department of respiration.

Background

With the progress of society, almost every person's house has a car, but when a large amount of cars gush the street, the exhaust gas that discharges also can cause very big pollution to the air to lead to many people now to have the disease in the aspect of the respiratory track, the medicine that uses when treating the respiratory track often need directly spout in patient's respiratory track, makes in patient's oneself inhale the respiratory track, just needs special respiratory track device of dosing.

Patent CN201220165435.8 discloses a simple respiratory tract drug delivery device, which aims at the current technology of applying drugs to respiratory tract or nasal cavity, and the device directly drops or sprays the drugs into the nasal cavity by hands, and also has a separate medicinal nasal plug dipping in the drug solution to be plugged into the nasal cavity, and the drugs are sucked into the respiratory tract by breathing. The technology of dropping or spraying the medicine into the nasal cavity can not well control the dosage, and the sudden medicine application can also cause excessive stimulation to the nasal cavity, so that the patient sneezes or coughs, the medicine is sprayed out of the nasal cavity, the medicine liquid is wasted, the patient also needs to keep the posture of raising the head, and the patient is easy to fatigue; the nasal plug is not convenient to continue to take medicine, the frequent nasal plugs are easy to hurt patients, the nasal cavity can not be excessively stimulated by the installed air-permeable medicine-storing nasal plug, and adverse reactions such as sneezing and the like can not be generated; the design of the medicine storage chamber solves the problem that the nasal obstruction alone is difficult to continue medicine; the arc-shaped medicine conveying pipe enables the patient not to be treated by always raising the head.

The above-mentioned administration devices have some disadvantages: 1. above-mentioned device of dosing is not convenient for store the medicine in the device earlier, doses again, directly says that the same direct medicine of dosing pipe and external device of dosing is not convenient for control the speed of dosing, makes the patient chock at the in-process of dosing easily, causes uncomfortable, has reduced the practicality of the device of dosing. 2. Above-mentioned device of dosing can only give a medicine alone, is not convenient for carry out the dosing of different kind medicines to the patient simultaneously, if need give different medicines, above-mentioned device of dosing need take out again from patient's respiratory track and inject patient's respiratory track again in, cause the patient to relapse uncomfortable, has reduced the practicality of the device of dosing.

Referring to fig. 1, the upper and lower sides of the medicine feeder 1 are symmetrical, when different medicines are needed to be fed simultaneously, different liquid medicines are poured into the medicine cavities 2 inside the upper and lower sides of the medicine feeder 1 simultaneously, the rotating knob 5 is rotated to drive the screw block 4 to rotate and enter the screw opening 3, the medicine cavities 2 are closed, the medicine feeder 1 is inserted into the respiratory tract of a patient from right to left, the left side of the medicine feeder 1 is trapezoidal and is matched with the entrance of the respiratory tract, discomfort of the patient caused by the fact that the medicine feeder 1 enters the respiratory tract is avoided, when the upper and lower sides of the medicine feeder 1 are extruded by the respiratory tract, the inner rod of the telescopic rod 17 installed at the center is compressed towards the center when the outer rod is extruded and contracted, the plastic spring B18 sleeved outside is extruded while the telescopic rod 17 is contracted, the plastic spring B18 is compressed, so that the medicine feeder 1 is more accordant with the entrance of the, extrude the medicine material, extrude medicine material with the extrusion head A15 and the extrusion head B16 of the upper and lower both sides of ware of dosing 1 simultaneously, be convenient for two kinds of medicine materials of difference, improved the effect of treatment, increased the practicality of the device of dosing.

The embodiment of the invention provides a clinical inhalation type administration device for respiratory medicine, when administration is needed to be carried out in the respiratory tract of a patient, a knob 5 is rotated manually, the knob 5 rotates to drive a screw block 4 fixedly arranged at the inner side to rotate, the screw block 4 is matched with the screw thread on the inner wall of a screw opening 3 through the screw thread cut on the outer wall, the screw block 4 rotates outwards in the screw opening 3, so that the screw block 4 is taken out, liquid medicine to be administered is poured into a medicine cavity 2, the knob 5 is rotated again to drive the screw block 4 to move inwards in the screw opening 3 to close the medicine cavity 2, medicine slurry is filled in a medicine pipe A6 which is communicated with the medicine cavity 2 and the right side and a medicine pipe B12 at the left side, a multilayer sealing gasket 10 fixedly arranged at the outer side of a rubber block 9 seals the medicine pipe A6, an extrusion type closed state formed by an extrusion head A15 and an extrusion head B16 which are made of rubber at the left side is stored in an administration device 1, the administration device 1 is slowly inserted into the, the connecting rod 8 is slowly pushed from right to left, the connecting rod 8 moves leftwards to drive the cylindrical rubber block 9 to move leftwards in the cylindrical medicine tube B12, the stretching plastic spring A11 converts kinetic energy into elastic potential energy, the volume of medicine stored in the medicine feeder 1 is unchanged, the rubber block 9 moves leftwards to reduce the volume of the medicine tube A6, so that medicine slurry in a sealed state moves leftwards under the action of pressure and is extruded into the medicine tube B12, the medicine slurry is slowly extruded from the extrusion head A15 and the largest extrusion head B16 which are sealed and uniformly distributed by rubber on the left side, the side extrusion heads A15 which are uniformly distributed enable the medicine to be sprayed more uniformly, meanwhile, a doctor can conveniently control the medicine feeding speed in a respiratory tract, a patient is prevented from being choked, when different medicines need to be fed simultaneously, different medicine cavities 2 in the upper side and the lower side of the medicine feeder 1 are simultaneously poured with different medicine liquids, the rotating knob 5 drives the screw block 4 to rotate to enter the screw opening, close medicine chamber 2, inject ware 1 in following the dextrad left side injects patient's respiratory track with dosing, the left shape of ware 1 of dosing is identical for trapezoidal entry with the respiratory track, it leads to the patient uncomfortable to have avoided 1 entering respiratory track of dosing ware, when the respiratory track that receives of ware 1 upper and lower both sides extrudees, when the interior pole of telescopic link 17 of installing at the center extrudees the shrink at the outer pole, with 1 to the central compression of ware of dosing, extrude the outside plastic spring B18 that cup joints in the time of telescopic link 17 shrink, compress plastic spring B18, thereby make ware 1 of dosing accord with the respiratory track entry more, promote connecting rod 8 left simultaneously, drive rubber block 9 and remove left, extrude the medicine material, will extrude first A15 and extrude first B16 with the extrusion of ware 1 upper and lower both sides simultaneously with the medicine material, be convenient for two kinds of medicine materials.

It will be apparent to those skilled in the art that various modifications and variations can be made in the embodiments of the present invention without departing from the spirit or scope of the embodiments of the invention. Thus, if such modifications and variations of the embodiments of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to encompass such modifications and variations.
