Description

  The present invention relates to a nasal spray, and more particularly to a nasal spray used to spray a liquid medicine into the nasal cavity.

  Currently, industrial development has rapidly progressed in various countries around the world, and land has been greatly developed, air pollution has become serious, and the amount of exhausted gas has been increasing day by day.

  Therefore, it is the main cause of nasal allergy for people with sensitive respiratory organs. It also causes a condition in which asthmatic patients cannot breathe normally.

  For this reason, since many people have health problems related to the respiratory tract, the health of the body functions must be maintained by appropriate eating and drinking.

  In addition, patients cannot spend their daily life comfortably and peacefully without using drugs and special instruments (such as nasal sprays).

  As mentioned above, nasal cavity injectors are an indispensable necessity for those who use nasal cavity injectors to protect the nasal cavity and asthma patients.

  Therefore, the emphasis is on whether it is suitable for practical use, whether it is sales promotion and attracting consumers.

  Conventionally, a nasal cavity injector 100 that is commonly seen generally includes an ejection head 101 having an ejection nozzle 101a and a cover 102 provided at one end below the ejection head 101, as disclosed in FIG. It becomes.

  The cover 102 has a seat tube 103 formed therein. The seat tube 103 is provided with an annular valve 103 a at the bottom end, and is connected to the conical tube 104.

  The conical tube 104 is provided with a ball 107 inside, a hole 104a provided on the outside is just blocked by the ball 107, and a tube body 105 is formed at the bottom end.

  The tube body 105 is provided with a spring 106 at one end. The storage tube 108 serves to provide the above-described seat tube 103, the conical tube 104, the tube body 105, and the spring 106 in the storage tube 108 in order from the top to the bottom.

  The storage pipe 108 is provided with an opening 108a at the bottom end, and a suction pipe 109 is provided below the opening 108a.

  When the above-described members are combined and then combined with a can (not shown) containing liquid medicine using the cover 102, the medicine liquid is sucked from the injection nozzle 101a and injected.

  As described above, when used, when the ejection head 101 is pressed, the air in the can body is instantaneously ejected from the ejection nozzle 101 a of the ejection head 101.

  At the same time, air enters the storage tube 108 from the suction pipe 109 together with the liquid medicine in the can body by the action of the siphon.

  At this time, the annular valve 103a of the seat tube 103 moves along the storage tube 108 downward on the inner wall surface. When the outer peripheral edge of the annular valve 103a contacts the opening 108a having a relatively small hole diameter, a sealed space is formed.

  For this reason, the liquid medicine reliably receives pressure and the liquid medicine provided in the storage tube 108 rapidly flows upward from the hole 104 a of the cone-shaped tube 104, and the liquid medicine is ejected from the ejection head 101 through the seat tube 103. From the injection nozzle 101a.

  When the ejection head 101 is opened, the liquid medicine in the can moves again from the suction pipe 109 into the storage pipe 108 together with air.

  FIG. 6 shows another conventional nasal cavity injector 200.

  According to the drawing, the nasal cavity injector 200 is provided with an ejection head 201 having an ejection nozzle 201 a on a cover 202.

  Since the upper end portion of the first tubular body 203 is formed in the slot 202 a of the cover 202, the first tubular body 203 is connected and combined with the ejection head 201.

  The first tube body 203 is provided with a second cover 204 at the bottom end and connected so as to cover the seat tube 205.

  The seat tube 205 is provided with a groove 205a provided in the upper stage, and is provided with a spring 206 in combination below. A ball 207 is provided below the spring 206, and the diameter gradually decreases from the top to the bottom. The ball 207 is provided in a storage tube 208 provided with a mouth portion 208a.

  A suction pipe 209 is provided at the bottom end of the storage pipe 208.

  After combining the above-described members, when the cover 202 is combined and connected to a can (not shown) filled with liquid medicine, the liquid medicine is ejected through the ejection nozzle 201a.

  When the above-described product is used, when the ejection head 201 is pressed, the air in the can body is instantaneously ejected from the ejection nozzle 201a of the ejection head 201, and the liquid medicine in the ejection head 201 is combined with the air by the siphon effect. Then, it flows from the suction pipe 209 into the storage pipe 208.

  Since the spring 206 elastically expands and contracts, the bottom of the seat tube 205 presses and presses the ball 207, and when the ball 207 closes the mouth 208 a of the storage tube 208, a gap is generated between the seat tube 205 and the second cover 204. The liquid medicine in the tube 208 flows out from the groove 205a at the outer edge of the seat tube 205 into the first tube body 203 along the gap.

  Liquid medicine and air are ejected from the ejection nozzle 201 a of the ejection head 201 through the first tube 203.

  When the ejection head 201 is opened, the liquid medicine in the can flows from the suction pipe 209 into the storage pipe 208 together with air.

  As described above, the conventional nasal cavity injectors (100, 200) can achieve the purpose of injecting liquid medicine, but the metal members such as the springs 106, 206, balls 107, 207 are all contained in the storage tube. 108 and 208.

  Accordingly, since the liquid medicine in the can comes into contact with the metal member for a long time, a chemical change occurs in the medicine, and the quality of the medicine easily changes.

  In addition, if a user who does not know the structure injects a modified medicine, it affects the safety of the human body and life, so the above-mentioned problems cannot be emphasized, and improvement is necessary.

  Furthermore, when discarding a modified drug, it is difficult to dilute and collect it, which pollutes the environment.

  The above-described conventional nasal cavity injectors 100 and 200 have a large number of members, increase production costs, are difficult to assemble and remove, and are not practical.

  An object of the present invention is to provide a nasal cavity ejector having a simple structure in which a drug does not contact a metal member.
