Description

Technical Field

[0001] The utility model belongs to the technical field of nasal medication devices, in particular to a nasal medication device. Background Art

[0002] A nasal drug delivery device is a medical device used to deliver drugs directly into the nasal cavity. It is suitable for the rehabilitation of symptoms such as acute and chronic rhinitis, allergic rhinitis, sinusitis, snoring, and nasal itching and congestion caused by colds. It is mainly used for drug delivery, injection and nasal care, as well as nasal protection. Commonly used nasal drug delivery devices are needle-tube structures.

[0003] Current nasal drug delivery devices are usually composed of a syringe, a piston slidably connected to the syringe, a pressing rod fixedly connected to one end of the piston, and an atomizing nozzle installed at the nozzle of the syringe. That is, the atomizing nozzle is removed, the medicine in the medicine bottle is sucked into the syringe by pulling the pressing rod, and the atomizing nozzle is reinstalled at the nozzle. The atomizing nozzle can be inserted into the nasal cavity, and pressure is applied to the pressing rod to generate a spray into the nasal cavity for drug delivery.

[0004] Syringes are usually disposable, but other people will collect undamaged syringes for secondary use. Reused syringes pose medical risks when used and are prone to cross infection. Therefore, a nasal drug delivery device is proposed to address the above problem. Utility Model Content

[0005] In order to make up for the shortcomings of the existing technology, a nasal drug delivery device is proposed to solve the problem that injection tubes are usually disposable, but other people will collect undamaged injection tubes for secondary use, and the secondary used injection tubes have medical risks when used and are prone to cross infection.

[0006] The technical solution adopted by the utility model to solve the technical problem is as follows: a nasal medicating device described in the utility model comprises a suction tube; a piston is slidably connected in the suction tube, one end of the piston is fixedly connected to a pressing rod, and the other end of the pressing rod extends out of the suction tube and is fixedly connected to a pressing block;

[0007] The suction tube is provided with a locking mechanism, which includes a limit block fixedly connected to the bottom of the pressing block, a limit groove being provided on one side of the limit block, a positioning block being slidably connected in the limit groove, one end of the positioning block being elastically connected to the inner side wall of the limit groove by a spring, and the other end of the positioning block extending out of the limit groove and inserted into the card slot provided in the inner side wall of the suction tube. Through the setting of the locking mechanism, the suction tube can be self-locked after a single use to avoid being picked up for secondary use by other persons.

[0008] Preferably, an adjustment groove is provided on one side of the outer wall of the pressing rod, and the inner wall of the adjusting groove is rotatably connected to an auxiliary block through a rotating shaft. Through the arrangement of the adjusting groove and the auxiliary block, the auxiliary block can be unfolded when the pressing rod is pulled out to assist in limiting the pressing rod, thereby avoiding the suction tube being locked due to accidental touch when operating the drug dispenser.

[0009] Preferably, the inner wall of the adjustment groove is fixedly connected to a first magnetic block, and the side of the auxiliary block close to the first magnetic block is fixedly connected to a second magnetic block. Through the cooperation of the first magnetic block and the second magnetic block, when the pressing rod is pulled out, the auxiliary block can expand automatically under the action of the magnetic poles, thereby simplifying the operating steps.

[0010] Preferably, there are two groups of limit blocks, and the two groups of limit blocks are symmetrically distributed. The end of the positioning block away from the spring is configured to be conical. By configuring the end of the positioning block away from the spring to be conical, the step of pressing the positioning block is simplified, thereby further improving the convenience of using the applicator.

[0011] Preferably, the outer wall of the suction tube is provided with scale lines, and the end of the suction tube away from the pressing block is provided in a conical column shape. The scale lines provided on the outer wall of the suction tube facilitate accurate observation of the sucked liquid medicine.

[0012] Preferably, an atomizing nozzle is provided at one end of the suction tube away from the pressing block, and a fixing block is fixedly connected to one side of the outer wall of the suction tube. The atomizing nozzle can be used to cooperate with the suction tube to atomize the medicine, which is convenient for absorption of the medicine. The setting of the fixing block makes it easy to hold the suction tube.

[0013] Preferably, the outer wall of the pressing block is provided with anti-skid patterns, and the outer wall of the fixing block is provided with anti-skid patterns. The friction force is improved by providing the anti-skid patterns on the outer wall of the pressing block and the outer wall of the fixing block.

[0014] Beneficial effects of the utility model:

[0015] 1. The utility model provides a nasal drug delivery device. Through the setting of the locking mechanism, when using the nasal drug delivery device, the medicine in the medicine bottle can be sucked into the suction tube, and the nasal drug delivery can be carried out in conjunction with the atomizing nozzle. During the drug delivery process, pressure is applied to the positioning block to retract it into the limiting groove, and the pressing block drives the limiting block to move downward synchronously, and the limiting block gradually enters the suction tube until the drug delivery is completed and the limiting block completely enters the suction tube. At this time, the limiting groove is aligned with the card slot. Under the pressure of the spring, the positioning block partially pops out and is stuck in the card slot, locking the movement of the pressing rod to make it immovable, so that the pressing rod can no longer be pulled out, completing the self-locking locking, and avoiding the possibility of the suction tube being picked up and reused by other people after use.
