Abstract
Description
Technical Field
[0001] This patent application relates to the field of medical device technology, specifically to the internal mechanism of a nasal spray, and more specifically to a gas pipeline connection device. Background Technology
[0002] Existing nasal delivery devices are generally designed with dust caps to prevent dust and other environmental contaminants from adhering to the nozzles. However, when administering medication through the nose, the nozzles need to be inserted into the patient's nasal cavity, and it is difficult to remove contaminants through cleaning and disinfection after long-term use. Therefore, the nozzles of nasal delivery devices are designed to be replaceable. When replacing the nozzles, or even when designed at the factory, the internal ventilation tubing of the nasal delivery device also needs to be properly sealed.
[0003] Most existing nasal delivery devices use a screw-in nozzle, with the medication and nozzle located in the same reservoir. This reservoir includes a gas channel and a liquid channel. The gas channel is connected to a compressor pump and a liquid storage chamber via a flexible tube. The liquid is atomized by the gas flow. The central hole is the gas channel, and the side holes are the medication channels. During use, the medication is poured into the reservoir, and the nozzle is screwed in. However, this rotating nozzle installation method makes precise alignment of the holes or tubing difficult for both medical personnel and patients, affecting the flow rate of the medication or gas and causing difficulties in dispensing or atomizing the medication, thus impacting the effectiveness of the device.
[0004] Therefore, in the development of a nasal drug delivery device, the precise alignment and sealing of the internal tubing of the device when changing the nozzle is an urgent problem to be solved. Utility Model Content
[0005] In view of this, the present invention provides a pipeline connection device to solve the problem of difficulty in liquid dispensing or atomization caused by the inaccurate alignment or sealing of the pipeline when changing the nozzle in a nasal drug delivery device.
[0006] This utility model is achieved through the following technical solution: This utility model provides a pipeline connection device, including: a nozzle, an air pump, and a gas channel, wherein the gas channel includes an upper gas connecting pipe and a lower gas connecting pipe.
[0007] Preferably, the gas connection pipe is detachably connected to the nozzle.
[0008] Preferably, the gas upper connecting pipe is further provided with a soft rubber sleeve; more preferably, the soft rubber sleeve is integral with the gas upper connecting pipe; even more preferably, the outer dimensions of the soft rubber sleeve are slightly larger than the inner diameter of the gas lower connecting pipe.
[0009] Preferably, the gas lower connecting pipe is fixedly connected to the gas pump.
[0010] Preferably, the inner wall of the gas connecting pipe is a smooth inner wall.
[0011] Preferably, the lower gas connecting pipe and / or the upper gas connecting pipe are provided with guide chamfers.
[0012] Preferably, the chamfer angle is 0-90°, such as 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80° or 90° and any value between two values.
[0013] Preferably, the hardness of the soft rubber sleeve is Shore hardness 10°-Shore hardness 80°.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. By setting up an upper gas connecting pipe and a lower gas connecting pipe, the nozzle of the nasal drug delivery device can be installed in a different way. The insertion connection replaces the existing rotary installation method, which is more conducive to the convenient installation of internal pipelines.
[0016] 2. By setting a soft rubber sleeve on the outer surface of the gas connecting pipe, the sealing problem when connecting the upper and lower gases is solved. At the same time, the soft rubber sleeve is set on the replaceable connecting pipe, which solves the wear problem caused by repeated assembly.
[0017] 3. The guide chamfers of the lower and upper gas connecting pipes, as well as the smooth inner wall of the lower gas connecting pipe, ensure smooth connection during the connection process. Attached Figure Description

Figure 1 , Figure 2 and Figure 3As shown, it includes: a nozzle 1, an air pump 5, and a gas channel, wherein the gas channel includes an upper gas connecting pipe 2 and a lower gas connecting pipe 3, and the upper gas connecting pipe 2 is also provided with a soft rubber sleeve 4, the soft rubber sleeve 4 being integrated with the upper gas connecting pipe 2.
[0028] In one specific embodiment, the gas upper connecting pipe 2 is detachably connected to the nozzle 1.
[0029] In one specific embodiment, the gas lower connecting pipe 3 is fixedly connected to the air pump 5.
[0030] In another specific embodiment, the outer dimensions of the soft rubber sleeve 4 are slightly larger than the inner diameter of the gas lower connecting pipe 3. Since the soft rubber sleeve 4 has elastic deformation, the sealing performance of the connection can be guaranteed when the outer dimensions of the soft rubber sleeve 4 are larger than those of the gas lower connecting pipe 3.
[0031] In one specific embodiment, the lower gas connecting pipe 3 and / or the upper gas connecting pipe 2 are provided with guide chamfers 6.
[0032] In one specific embodiment, the inner wall of the lower gas connecting pipe 3 is a smooth inner wall to facilitate the smooth connection between the upper gas connecting pipe 2, which is fitted with a soft rubber sleeve, and the lower gas connecting pipe 3.
[0033] In one specific embodiment, the chamfer angle of the guide chamfer 6 is 0-90°, such as 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80° or 90° and any value between two values, which is not limited here, as long as it can achieve a smooth connection between the gas upper connecting pipe 2 and the gas lower connecting pipe 3.
[0034] In one specific embodiment, the hardness of the soft rubber sleeve 4 is Shore hardness 10° to Shore hardness 80°.
[0035] The working process of this utility model is as follows:
[0036] When the separate nozzle 1 needs to be connected to the main body of the nasal delivery device, the upper gas connecting tube 2 and the lower gas connecting tube 3 are connected by a guide chamfer 6, while simultaneously squeezing the soft rubber sleeve 4 to form a reliable seal, ensuring that the airtightness is not affected by the insertion distance of the upper and lower gas connecting tubes. When the air pump 5 is working, the gas flows along the air tube bend, the lower gas connecting tube 2, and the upper gas connecting tube 5 to the nozzle 1. When disassembly is required, the nozzle 1 is removed vertically, and the upper gas connecting tube 2 is also pulled out.
[0037] The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various changes or modifications within the scope of the claims, which do not affect the substantive content of this utility model.
