Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a spray counting structure and a spray device. Background Art
[0002] Inhalation therapy has become a common drug delivery method in clinical practice. The drug delivery device used in inhalation therapy can directly atomize and spray the atomized drug, which is then inhaled directly through the nose or mouth. The drug can be directly absorbed into the bloodstream or act locally, avoiding the first-pass effect in the liver and reducing the dosage.
[0003] In the prior art, patients operate a drug delivery device to administer medication, and while the device performs the spraying process, patients cannot intuitively monitor their medication usage. For example, with a pressure-controlled metered-dose drug delivery device, the total number of sprays per bottle is fixed, making it difficult for patients to determine how many sprays have been used and how many are left. This makes it difficult for patients to determine whether to restock medication, and can lead to patients using a drug delivery device with insufficient medication, resulting in missed doses.
[0004] Therefore, how to enable patients to intuitively learn about drug usage through drug delivery devices is a problem that urgently needs to be solved. Utility Model Content
[0005] The purpose of the utility model is to provide a spray counting structure and a spray device, which can help patients know the number of times the medicine has been used through a counting ring, thereby improving the convenience of using the device.

[0037] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make this disclosure more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. Identical reference numerals in the figures denote identical or similar structures, and thus repeated descriptions thereof will be omitted.
[0038] The words expressing positions and directions described in this utility model are all explained with reference to the accompanying drawings as examples, but they can be changed as needed, and all such changes are included in the protection scope of this utility model.
[0039] See also Figures 1 to 6 As shown, the utility model discloses a spray counting structure, which includes an attachment sleeve 1, a counting ring 2 and a pressing cover 3.
[0040] The attachment sleeve 1 is attached to the opening of the container (not shown) to connect the spray counting structure to the container, thereby realizing the counting function. For example, Figure 3 As shown, the attachment sleeve 1 can be fixedly installed at the opening of a container (such as a bottle) by means of a threaded connection to ensure a stable and firm connection and good sealing performance.
[0041] Figure 2 The attachment sleeve 1 is shown with a ratchet 11 disposed on its outer periphery. The ratchet 11 is used to cooperate with the counting ring 2 to restrict its rotation to a single direction, for example, clockwise, thereby preventing counting anomalies caused by reverse rotation of the counting ring 2 and improving counting reliability. In this application, the ratchet 11 can be integrally formed in the middle of the attachment sleeve 1.
[0042] Combine Figure 3 and Figure 4 As shown, the counting ring 2 is rotatably sleeved on the attachment sleeve 1. A plurality of check plates 21 are provided at intervals on the inner side of the counting ring 2 to form a one-way intermittent motion with the ratchet 11. For example, the number of check plates 21 is usually 5-8, so as to ensure that the counting ring 2 is subjected to balanced force and improve the stability of the one-way rotation. Figure 6 As shown, in the present application, the check plate 21 is obliquely formed on the inner side of the counting ring 2 and has a certain elasticity, so that when the counting ring 2 rotates clockwise, the check plate 21 can pass over the tooth on the current ratchet 11 and form a stop with the next tooth in the counterclockwise direction.
[0043] In addition, a number of driven ribs 22 are arranged at intervals on the outside of the counting ring 2 to cooperate with the active ribs 31 on the inside of the pressing cover 3 to promote the intermittent rotation of the counting ring 2. Figure 2 As shown, in the present application, the driven rib 22 is vertically formed in the upper end area of the counting ring 2, and a second inclined surface 221 is provided on the top of the driven rib 22, which is inclined downward, so that it can drive the counting ring 2 to rotate in a specific direction after being acted upon by the active rib 31.
[0044] It can be seen that the check piece 21 of the counting ring 2 is located on the inner side of the ring. Considering that the check piece 21 is a relatively vulnerable part, its built-in design can play a certain protective role.
[0045] like Figure 3 and Figure 4 As shown, the pressing cover 3 is slidably connected to the attachment sleeve 1 , and the two can be guided by a guide unit (guide groove 13 , guide rib 33 ) so that the pressing cover 3 can move up and down relative to the attachment sleeve 1 .
[0046] Figure 5The push cover 3 is shown with active ribs 31 spaced apart on its inner side, which are used to cooperate with the driven ribs 22 on the outer side of the counting ring 2 to drive the counting ring 2 to rotate intermittently. In this application, the active ribs 31 are vertically formed in the upper end area of the push cover 3. In the initial state, they maintain a certain distance from the driven ribs 22. The bottom of the active ribs 31 is provided with a first inclined surface 311, which is also inclined downward so that it contacts the second inclined surface 221 to drive the counting ring 2 to rotate in a specific direction.
[0047] In this spray counting structure, the elastic engagement between the check plate 21 and the ratchet 11 causes the counting ring 2 to rotate in only one direction. When the pressing cover 3 moves downward, it can cause the counting ring 2 to rotate and count once through the inclined guide feature (the active rib 31 can contact the driven rib 22).
[0048] The specific usage process is as follows:
[0049] S1. Install the attachment sleeve 1 at the opening of the container and connect the push cap 3 to the pump in the container (not shown);
[0050] S2. Press the pressing cover 3 and compress the spring inside the pump at the same time. During this period, the active rib 31 contacts the driven rib 22 and causes the counting ring 2 to rotate in one direction. Each time the pressing is done, the counting ring 2 rotates one grid and counts once.
[0051] S3, the pressing force is canceled, and the pressing cover 3 is reset under the action of the spring in the pump. During this period, the check piece 21 is engaged with the ratchet 11, and the counting ring 2 is restricted from reversing.
[0052] The spray counting structure of the present application can realize the counting function of pressing and counting through the cooperation of the active rib 31 and the driven rib 22, the check piece 21 and the ratchet 11, which is convenient for patients to use and greatly improves convenience.
[0053] See also Figure 1 As shown, in some embodiments, the counting ring 2 is sequentially arranged in the circumferential direction with counting scales 23. The counting scales 23 can be directly engraved on the circumference of the counting ring 2 or adhered to the circumference of the counting ring 2 in the form of stickers. In addition, a viewing window 32 corresponding to the counting scale 23 is provided at the bottom of the pressing cover 3. The viewing window 32 is in the shape of an arch and can only accommodate one counting scale 23 at a time.
[0054] By displaying the number of presses in the form of a counting scale 23, the number of times the medicine has been used can be known, and information such as whether the medicine has been used and the number of remaining sprays can be confirmed, so that the patient can make decisions such as whether to prepare the medicine or use the medicine, which is convenient for the patient to use.
[0055] Furthermore, a fluorescent layer (not shown) is provided on the surface of the counting scale 23 , which enables the counting scale 23 to be displayed normally even in a dim environment, making it convenient for patients to use.
[0056] See also Figure 2 and Figure 3 As shown, in some embodiments, the outer periphery of the attachment sleeve 1 is provided with an annular groove 12, which is located below the ratchet 11. Correspondingly, the inner side of the counting ring 2 is provided with a protruding buckle 24, which is located below the check plate 21 and matches the annular groove 12.
[0057] When the convex buckle 24 is installed, it is set in the annular groove 12 without affecting the normal rotation of the counting ring 2. The convex buckle 24 cooperates with the annular groove 12 to guide the counting ring 2 to rotate stably and limit its separation from the attachment sleeve 1.
[0058] See also Figures 2 to 5 As shown, in some embodiments, the top of the attachment sleeve 1 is provided with guide grooves 13. The guide grooves 13 may be located above the ratchet 11 and are evenly spaced along the periphery of the attachment sleeve 1. Accordingly, the inner side of the pressing cover 3 is provided with guide ribs 33 that slidably engage with the guide grooves 13. Together, the two constitute the aforementioned guide unit, allowing the pressing cover 3 to only move up and down relative to the attachment sleeve 1 without rotating, thereby preventing the rotation of the viewing window 32 from affecting the counting accuracy.
[0059] Furthermore, a convex edge 14 is provided between the tops of adjacent guide grooves 13, and a barbed hook 34 is provided between the bottoms of adjacent guide ribs 33. The barbed hook 34 is buckled under the convex edge 14 to prevent the pressing cover 3 from detaching from the attachment ring when it is reset, thereby playing an anti-detachment role.
[0060] In some embodiments, the angle between the first inclined surface 311 and the horizontal plane is 40°-50°, preferably 45°, and the second inclined surface 221 is parallel to the first inclined surface 311 to ensure a better actuation effect.
[0061] See also Figure 2 and Figure 6 As shown, in some embodiments, a limiting portion 15 is provided on the outer periphery of the attachment sleeve 1 , and the limiting portion 15 is located below the annular groove 12 . Accordingly, a stopper 25 corresponding to the limiting portion 15 is provided on the inner side of the counting ring 2 .
[0062] When the stopper 25 and the limiting part 15 collide with each other, the two parts interfere with each other and thus restrict the counting ring 2 from continuing to rotate, which means that the counting function of the spray counting structure fails and new medicine needs to be replaced.
[0063] See also Figure 3 As shown, in some embodiments, a one-way tooth ring 16 is provided below the attachment sleeve 1 for cooperating with the teeth on the container to form a locking structure, thereby permanently fixing the attachment sleeve 1 on the container to prevent theft.
[0064] The utility model also discloses a spray device, such as a nasal sprayer, comprising the above-mentioned spray counting structure. By being equipped with the spray counting structure, the spray device has a press-to-count function, which is convenient for patients to use.
[0065] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limiting the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the utility model without departing from the principles and purpose of the utility model. All of these changes should fall within the scope of protection of the claims of the present invention.
