Description

Technical Field

[0001] The present invention relates to the field of otolaryngology mixed drug delivery devices, and particularly to an otolaryngology mixed drug delivery device. Background Art

[0002] Special drug delivery devices for otolaryngology are specifically used for the treatment of some diseases related to the ear, nose, and throat in otolaryngology. One of the more common drug delivery devices consists of a drug delivery tube, a drug outlet head, and a drug pushing rod. When in use, the medicine is inhaled into the tube, then the drug tube is inserted into the diseased area, and at the same time, the drug outlet head is aligned with the lesion, and the medicine is squeezed out of the drug outlet head by pushing the push rod, so that the medicine contacts the lesion of the patient. This is a drug delivery device with the widest range of use at present.

[0003] However, some existing drug delivery devices are usually large-sized machinery and are not convenient to carry around. Moreover, since the lesion areas in the ear, nose, and throat are generally small, the drug delivery openings are usually narrow and thin nozzles. During the drug delivery process, the mixed medicine drips onto the lesion through the narrow pipe. However, during the drug delivery process, impurities in the liquid medicine are easily blocked at the drug delivery opening, making it difficult for the drug to pass through the narrow nozzle.

[0004] Therefore, it is necessary to provide a new otolaryngology mixed drug delivery device to solve the above technical problems. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides an otolaryngology mixed drug delivery device that is easy to peel off.

[0029] Refer to Figure 1 、 Figure 2 and Figure 3 As shown in Figure 2 and Figure 3 , a lighting lamp 8 is arranged at the bottom end of the manifold 7. A control valve 9 is arranged on the medicine tube 5. A limiting ring 10 is sleeved on the outside of the transmission sleeve 41. The top and bottom of the limiting ring 10 are connected to the inner wall of the connecting pipe of the nozzle 3.

[0030] It should be noted that: the lighting lamp 8 is fixedly connected to the inside of the manifold 7 by a bolt. The control valve 9 is an electromagnetic valve. A control module is arranged inside the handle 1. The push button switch 12 is signal - connected to the control module. The control valve 9 and the blower are both signal - connected to the control module. When the push button switch 12 is pressed, the control valve 9 opens and the blower starts.

[0031] The working principle of an ENT mixed medicine administration device provided by the present invention is as follows:

[0032] In use, according to the actual usage requirements, insert the medicine bottle 11 onto the needle 27. When the length of the medicine bottle 11 is too long, the pressing block 23 can be pulled. The pressing block 23 drives the limiting rod 24 to move upward. The limiting rod 24 stretches the tension spring 26. When inserting the longer medicine bottle 11 onto the needle 27, release the pressing block 23, so that the buffer block 25 at the bottom of the pressing block 23 fits against the top of the medicine bottle 11 for clamping and fixing. The medicine inside the medicine bottle 11 enters the inside of the medicine dropping pipe 28 through the needle 27 for mixing and then enters the inside of the medicine pipe 5. At this time, the button switch 12 can be pressed. The button switch 12 controls the control module to turn on the control valve 9 and the fan. The medicine enters the connecting pipe inside the nozzle 3 through the control valve 9. The air flow generated by the fan enters the connecting pipe through the air inlet pipe 6. There is a constriction inside the connecting pipe. When the air flow passes through the constriction, the flow rate will increase. Under the action of the air flow, the liquid medicine falling into the connecting pipe will be dispersed by the air flow and sprayed out from the nozzle of the nozzle 3. When the liquid medicine contacts the dispersing piece 49, it will be further dispersed to expand the spraying range. To prevent the nozzle of the nozzle 3 from being blocked by foreign objects, the motor 42 drives the transmission plug rod 43 to rotate slowly. The transmission plug rod 43 drives the transmission sleeve 41 to rotate slowly through the convex rod 44. The transmission sleeve 41 drives the driving groove 45 to rotate slowly. Since the shape of the driving groove 45 is wavy and uneven, when the pulley 46 moves to the concave part, it will drive the transmission sleeve 41 to retract into the connecting pipe inside the nozzle 3. When the pulley 46 moves to the convex part, it will drive the transmission sleeve 41 to extend out of the connecting pipe of the nozzle 3. Due to the shape of the driving groove 45, the transmission sleeve 41 can reciprocate inside the connecting pipe, so that the dispersing piece 49 at one end of the transmission sleeve 41 can disperse the foreign objects blocking the nozzle of the nozzle 3.

[0033] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
