[0033] like Figures 1 to 5 As shown, this embodiment provides a nasal spray device, including: a bottle body 1, a pump valve 2 and a pressure cover 3.
[0034] like Figure 2 As shown, the pump valve 2 is connected to the bottle mouth 11 of the bottle body 1, and is used to pump the liquid in the bottle body 1. The pump valve 2 is, for example, a press valve that is pressed to spray out a spray. The pump valve also has a pump tube, which goes deep into the bottle body 1 to suck the liquid in the pump body 1. The axial direction of the pump valve 2 is consistent with the axial direction of the bottle body 1. Along its axial direction, the bottle body 1 is at the bottom and the pump valve 2 is at the upper part of the bottle body 1. Preferably, the pump valve 2 is sealed and connected to the bottle body 1. More preferably, the pump valve 2 is detachably connected to the bottle body 1.
[0035] Along the axial direction of the pump valve 2 and from the top to the bottom of the nasal spray device, the pump valve 2 includes a nozzle 22, a pump valve edge 21, a pump pressure device and a pump tube in sequence. The pump pressure edge 21 of the pump valve 2 can be pressed to achieve relative movement with the bottle body 1, thereby spraying out the spray. The pump pressure device is the pumping mechanism of the pump valve. Those skilled in the art can refer to the existing technology, which will not be repeated here.
[0036] like Figure 1 and Figure 2 As shown, the gland 3 is detachably arranged at the pump valve 2. For example, in this embodiment, when installed, the gland 3 can pass through the pump head 22 and be stuck on the pump valve 2 through the pumping edge 21.
[0037] like Figure 2As shown, the gland 3 has a first gland plane 31 and a second gland plane 32. Along the axial direction of the gland 3 (it should be understood that the axial direction of the gland 3 is consistent with the axial direction of the bottle body 1), the second gland plane 32 and the first gland plane (31) are in different axial positions, and the radial extension of the second gland plane 32 is larger than the radial extension of the first gland plane 31. The first gland plane 31 is used to be pressed on the pump pressure edge 21, and the second gland plane 32 is used to be pressed to press the pump pressure edge 21 in a linked manner, thereby realizing the function of enlarging the size of the pump valve 2. When the patient is in use, the spray can be sprayed by pressing the second gland plane 32 with a larger size, thereby solving the problem of inconvenience in grasping and pressing when the patient holds it, thereby improving the accuracy of the dosage delivery and improving the treatment effect. In addition, the nasal spray device provided in this embodiment has a simple structure, and only one gland 3 structure is needed to realize the function of the method pump valve 2 structure, thereby reducing the probability of spray damage. Preferably, the bottle body 1 can contain a solution, and the solution can be physiological saline, sea salt water, a drug-containing solution, or the like.
[0038] Preferably, the pumping edge 21, the first gland plane 31 and the second gland plane 32 are annular planes. The pumping edge 21 is annularly arranged at the bottom outer edge of the nozzle 22, and the first gland plane 31 is shaped like the pumping edge 21, so that the first gland plane 31 contacts the pumping edge 21 and can drive the external force applied by the transmission.
[0039] Preferably, the design of the annular structure can make the pumping edge 21, the first gland plane 31, and the second gland plane 32 coaxially arranged, and the coaxial arrangement can make the force applied by the second gland plane 32 consistent with the force received by the pumping edge 21, even if the second gland plane 32 enlarges the structure of the pumping edge 21, but does not change the magnitude of the force received. When pressing, the patient can accurately grasp the pressing force, and will not be unable to grasp and determine the amount of the pumped spray due to the complex conduction structure.
[0040] Preferably, the gland 3 also includes a first wall 33 and a second wall 34, the first wall 33 is connected between the first gland plane 31 and the second gland plane 32 along the axial direction of the gland 3, so that the gland 3 is stepped; the second wall 34 is extended along the axial direction of the gland 3, the first wall 33 and the second wall 34 are cylindrical structures, and the gland 3 is buckled on the bottle body 1.
[0041] Preferably, along the radial direction of the gland 3, the second gland plane 32 protrudes radially, and the radial dimension of the cylinder formed by the second wall 34 is smaller than the radial dimension of the outer edge of the second gland plane 32. In this way, the profile of the gland 3 can be reduced without affecting the use of the second gland plane 32.
[0042] Optionally, the second pressing cover plane 32 further includes a pressing piece component protruding radially along the pressing cover 3, and the pressing piece component is used for pressing, which makes it more convenient for the patient to press.
[0043] Preferably, the gland 3 further includes a gland opening 35 , and the pump valve 2 further includes a nozzle 22 , and the gland opening 35 is arranged to avoid the nozzle 22 , thereby facilitating the installation of the gland 3 .
[0044] Preferably, Figure 5 As shown, the nasal spray device also includes a nozzle protection cover 4, which is detachably arranged on the nozzle 22; the size of the opening 41 of the nozzle protection cover 4 is smaller than the size of the pressure cover opening 35, and the nozzle protection cover 4 is used to be accommodated between the pressure cover opening 35 and the nozzle 22, so as to keep the nozzle 22 clean.
[0045] Preferably, along the circumference of the second wall body 34 , the second wall body 34 further has at least one groove 341 , and the groove 341 is used as a mark to identify the circumferential position.
[0046] Preferably, along the axial direction of the bottle body 1, the bottle body 1 is composed of a bottle mouth 11, a first bottle body 12 and a second bottle body 13 in sequence; the radial dimension of the first bottle body 12 is smaller than the radial dimension of the second bottle body 13, and the first bottle body 12 can be accommodated in the cylindrical structure formed by the second wall body 34, thereby reducing the axial dimension of the nasal spray device, so that the nasal spray device has a compact structure and is easy to carry.

Such a design realizes the function of enlarging the size of the pump valve. When the patient is in use, the spray can be sprayed by pressing the second gland plane with a larger size, thereby solving the problem of inconvenience in grasping and pressing when the patient holds it, thereby realizing accurate drug delivery and improving the treatment effect. In addition, the nasal spray device has a simple structure, and only one gland structure is needed to realize the function of the method pump valve structure, thereby reducing the probability of spray damage.
