PORTABLE MEDICAL SPRAY

Abstract

A portable medical spray includes a tubular body having a room defined therein, and a breakable portion is formed to the top end of the body. A connection portion extends from the bottom end of the body. A nozzle is connected to the top end of the body. The nozzle has a passage which is located corresponding to the breakable portion. A medicine cell is located in the room of the body and has medicine received therein. The medicine cell is a compressible bellow cell. A needle is located in the medicine cell. An end part is mounted to the connection portion. The end part is pushed toward the nozzle to compress the medicine cell, and the needle penetrates through the top end of the medicine cell and the breakable portion to release the medicine via the nozzle.

Claims

DETAILED DESCRIPTION OF THE INVENTION

[0016] Referring to FIGS. 1 to 3, the portable medical spray of the present invention comprises a tubular body 1 having a room 10 defined therein. A breakable portion 11 is formed to the top end of the body 1. A connection portion 12 extends from the bottom end of the body 1. A top groove 120 and a bottom groove 121 are respectively formed to the outside of the connection portion 12. A nozzle 13 is connected to the top end of the body 1, and has a passage 14 defined therethrough. The passage 14 is located corresponding to the breakable portion 11. A holding portion 17 is formed to the outside of the body 1 and includes two finger flanges. The passage 14 of the nozzle 13 of the body 1 has a valve 15 received therein. An adjustment knob 16 is connected to the nozzle 13 by a rod which extends through the nozzle 12 so that the valve 15 is operated by rotating the adjustment knob 16. A cap 2 is removably mounted to the nozzle 13.

[0017] A medicine cell 3 is located in the room 10 and has medicine “A” received therein under pressure. The medicine cell 3 is a compressible bellow cell. A needle 30 is located in the medicine cell 3. An end part 4 has a reception space 40 defined in the top end thereof, and the end part 4 has a closed bottom end. The end part 4 is movably mounted to the connection portion 12 which is inserted in the reception space 40. A lip 41 extends inward from the inner periphery of the reception space 40. Multiple slots 42 are defined axially through the wall of the end part 4 and open through the lip 41. When the end part 4 is not pushed toward the nozzle 13, the lip 41 is removably engaged with the bottom groove 121 of the connection portion 12.

[0018] As shown in FIGS. 3 to 6, when in use, the cap 2 is removed from the nozzle 13, and the adjustment knob 16 is rotated to adjust the valve 15 to set the amount of the medicine “A” to be injected. The user uses two fingers to holds the body 1 and the two fingers put on the finger flanges of the holding portion 17. The nozzle 13 is then inserted into the patient's nose as shown in FIG. 6. The user then uses the thumb to push the end part 4 toward the needle 30 or the nozzle 13. As shown in FIG. 5, the lip 41 is removed from the bottom groove 121 and is engaged with the top groove 120 when the end part 4 is moved toward the nozzle 13. The medicine cell 3 is compressed and by the movement of the end part 4, and the needle 30 penetrates through the top end of the medicine cell 3 and the breakable portion 11 of the body 1. The medicine “A” in the medicine cell 3 then ejects into the patient's nose through the passage 14 of the nozzle 13.

[0019] The medicine cell 3 can be replaced with a new one in which different medicine “A” is stored. The portable medical spray of the present invention is compact for easy carry.

[0020] While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
