Detailed implementation manners

[0032] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0033] Next, refer to Figures 1 to 12 Describe the administration assistance device 100 of the spray bottle provided according to some embodiments of the present invention. Among them, the spray bottle 200 can be an eye medicine spray bottle, a nasal medicine spray bottle, an oral medicine spray bottle, or other medicine spray bottles 200. As Figure 1 shown, the present invention takes the spray bottle 200 as an eye medicine spray bottle as an example to specifically illustrate the administration assistance device 100. It can be understood that the administration device of the spray bottle 200 can also be applied to other scenarios. As Figure 1 shown, the spray bottle 200 includes a bottle body 210 and a spray head 220. The spray head 220 is provided with a medicine spraying port 221. The axis of the medicine spraying port 221 is perpendicular to the axis of the bottle body 210. Thus, pressing the spray head 220 can cause the liquid medicine contained in the bottle body 210 to be sprayed out through the medicine spraying port 221.

[0034] As Figures 2 to 12 shown, the present invention provides an administration assistance device 100 for a spray bottle, including: a guide cover 110. The guide cover 110 is a hollow conical structure having a small-diameter port 111 and a large-diameter port 112. The small-diameter port 111 is communicated with the medicine spraying port 221. An operation port 115 is opened on the lower side wall of the guide cover 110.

[0035] As Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 11 and Figure 12As shown in the figure, the drug administration assistance device 100 of the spray bottle provided by the present invention, the guiding cover 110 is used to contact the user's drug administration position. For example, when the spray bottle 200 is an eye medicine spray bottle, the large-diameter port 112 of the guiding cover 110 is used to abut against the user's face to cover the eyes. Since the small-diameter port 111 of the guiding cover 110 is communicated with the medicine spraying port 221 on the spray bottle 200, thus, when the liquid medicine enters the guiding cover 1110 through the medicine spraying port 221 and the small-diameter port 111, it will act on the user's eyes through the large-diameter port 112, realizing the drug administration operation for the eyes. The structure is simple and the operation is convenient. At the same time, the setting of the guiding cover 110 has a good protective effect on the liquid medicine sprayed from the medicine spraying port 221, can exclude the interference of external factors (such as air flow, dust, bacteria, etc.) during the drug administration process, improve the accuracy of the drug administration direction, achieve accurate drug administration, and is beneficial to ensuring the hygiene and cleanliness of drug administration. Among them, the setting of the operation port 115 facilitates the user to insert a hand or other tool through the operation port 115 into the inside of the guiding cover 110 to operate the user's drug administration position, so as to further improve the accuracy of the drug administration position, achieve accurate drug administration, and enable the medicine to better achieve the expected effect.

[0036] Specifically, taking the spray bottle 200 for eye medicine as an example, during the process of using the drug administration assistance device 100 for drug administration, the user's finger can intervene through the operation port 115 to control the opening and closing degree of the lower eyelid, so as to improve the accuracy of the drug administration position.

[0037] Among them, such as Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 As shown in the figure, the operation port 115 is opened on the lower side wall of the guiding cover 110, which facilitates the user's finger to extend into the inside of the guiding cover 110 through the operation port 115 at the lower part of the guiding cover 110 to control the opening and closing degree of the lower eyelid, so as to further improve the accuracy of the drug administration position. This kind of design meets the design requirements of ergonomics.

[0038] Among them, such as Figure 7 、 Figure 11 and Figure 12 As shown in the figure, the area inside the guiding sleeve 120 gradually increases from the small-diameter port 111 to the large-diameter port 112, that is, the inside of the guiding sleeve 120 is a smooth and gradually expanding flared structure. Thus, it can play a good guiding role and improve the drug administration accuracy.

[0039] Such as Figure 7 、 Figure 11 and Figure 12 As shown in the figure, in some possible implementation embodiments provided by the present invention, the operation port 115 extends towards the large-diameter port 112 of the guiding cover 110 and is communicated with the large-diameter port 112, forming a U-shaped opening.

[0040] Since the large-diameter port 112 covers the medication position, the operation port 115 is communicated with the large-diameter port 112, facilitating the user to directly and accurately operate the medication position with fingers or tools, further improving the accuracy of the administration position, being convenient to operate, and being able to improve the accuracy of the operation.

[0041] Among them, the operation port 115 is set as a U-shaped opening, and the U-shaped operation port 115 is not communicated with the small-diameter port 111 of the guiding cover 110. On the basis that the operation port 115 facilitates the user to operate the medication position, it ensures that the guiding cover 110 has a good protection and anti-interference effect. At the same time, the edges of the U-shaped operation port 115 are smoothly transitioned, avoiding the problem that the edges of the operation port 115 are right-angled transitions and scratching the user's fingers, and improving the safety of the user's operation.

[0042] Among them, as Figure 12 shown, the linear distance of the operation port 115 in the circumferential direction of the guiding cover 110 is 20 mm to 25 mm, that is, Figure 12 the size of d1 in Figure 11 is 20 mm to 25 mm. As Figure 11 shown, the size of the operation port 115 in the axial direction of the guiding cover 110 is 18 mm to 22 mm, that is, Figure 11 the size of d2 in

[0043] is 18 mm to 22 mm. By reasonably setting the size of the operation port 115, it can facilitate the user's finger to smoothly extend into the guiding cover 110 and be removed from the guiding cover 110, and have as little impact on the administration accuracy as possible.

[0044] Specifically, the linear distance of the operation port 115 in the circumferential direction of the guiding cover 110 can be 20 mm, 22 mm, 24 mm, 25 mm, or other sizes; the size of the operation port 115 in the axial direction of the guiding cover 110 is 18 mm, 19 mm, 20 mm, 22 mm, or other sizes.

[0044] As Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 and Figure 9 shown, in some possible implementation embodiments provided by the present invention, the administration assistance device 100 further includes a guiding sleeve 120 sleeved on the spray bottle 200. The guiding sleeve 120 has a cylindrical structure with an open bottom end 121. A through hole 123 is opened at a position corresponding to the medicine spraying port 221 of the spray bottle 200 on the guiding sleeve 120. The small-diameter port 111 of the guiding cover 110 is connected to the guiding sleeve 120 at a position corresponding to the through hole 123 of the guiding sleeve 120, and the medicine spraying port 221, the through hole 123, and the small-diameter port 111 are communicated with each other.

[0045] In this embodiment, the guide cover 110 and the spray bottle 200 are connected through the guide sleeve 120, and the medicine spraying port 221 and the small-diameter port 111 are communicated through the through hole 123 on the guide cover 110. Thus, operating the spray bottle 200 enables the liquid medicine in the spray bottle 200 to act on the user's medication position through the medicine spraying port 221, via the through hole 123, the small-diameter port 111, and the large-diameter port 112. The operation is simple and the use is convenient.

[0046] Meanwhile, connecting the guide cover 110 and the spray bottle 200 through the guide sleeve 120 can improve the reliability and stability of the connection between the guide cover 110 and the spray bottle 200, and reduce the problems of complex connection structure and unreliable connection when the guide cover 110 is directly connected to the spray bottle 200.

[0047] Among them, as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , Figure 9 shown, the guide cover 110 and the guide sleeve 120 can be vertically arranged so that the axis of the guide cover 110 coincides with the axis of the through hole 123 of the guide sleeve 120. In this way, when the spray bottle 200 is inserted into the guide sleeve 120 through the opening 121 and the medicine spraying port 221 is relatively communicated with the through hole 123, that is, the axis of the bottle body 210 coincides with or is parallel to the axis of the opening 121. Thus, pressing the spray head 220 in the direction of the axis of the opening 121 can enable the liquid medicine to be sprayed out through the medicine spraying port 221, the through hole 123, the small-diameter port 111, and the large-diameter port 112, so as to realize the administration operation of the spray bottle 200 with the axis of the medicine spraying port 221 perpendicular to the axis of the bottle body 210. The structure is simple and the operation is convenient.

[0048] As Figure 2 , Figure 3 shown, in some possible implementation embodiments provided by the present invention, the guide sleeve 120 is provided with a limiting structure 124 for cooperating with the spray head 220. Thus, the limiting structure 124 on the guide sleeve 120 is used to limit the spray head 220, so that the medicine spraying port 221 on the spray head 220 can be smoothly and accurately communicated with the through hole 123, so as to realize fixed-point administration, which is beneficial to further improving the accuracy of administration, ensuring the accuracy of the administration dose and the administration position, improving the use effect of the medicament, enabling the medicament to better achieve the expected effect, and realizing the function of standardizing and simplifying the administration process, and is suitable for popularization and application.

[0049] Specifically, the shape of the bottom opening 121 of the guide sleeve 120 matches a part of the shape of the spray bottle 200, so that the spray head 220 on the spray bottle 200 can be inserted into the guide sleeve 120 through the opening 121 and is restricted by contacting the limiting structure 124 in the guide sleeve 120, and the medicine spraying port 221 of the spray bottle 200 is opposite to and communicated with the through hole 123. At the same time, since the through hole 123 is communicated with the small-diameter port 111 of the guide cover 110, therefore, operating the spray bottle 200 enables the liquid medicine in the spray bottle 200 to act on the user's medication position through the medicine spraying port 221, via the through hole 123, the small-diameter port 111, and the large-diameter port 112. Furthermore, the administration operation of the spray bottle 200 with the axis of the medicine spraying port 221 perpendicular to the axis of the bottle body 210 is realized, with a simple structure and convenient operation.

[0050] As Figure 2 , Figure 3 , Figure 4 , Figure 8 , Figure 9 As shown in, in some possible implementation embodiments provided by the present invention, the spray head 220 is non-circular, and the limiting structure 124 includes an annular limiting seat 1242 connected to the top of the guide sleeve 120 and matching the shape of the spray head 220. The annular limiting seat 1242 is used to accommodate the spray head 220 to limit the circumferential rotation of the spray head 220 relative to the annular limiting seat 1242. An avoidance opening 126 is provided at the position of the annular limiting seat 1242 corresponding to the medicine spraying port 221 of the spray head 220.

[0051] Thus, the annular limiting seat 1242 can reliably limit the spray head 220, reducing the possibility of the circumferential rotation of the spray head 220 relative to the annular limiting seat 1242, so that the spray head 220 can be reliably and stably restricted in the guide sleeve 120 to achieve positioning administration. At the same time, the setting of the avoidance opening 126 can ensure that the medicine spraying port 221 of the spray head 220 is reliably, stably, and accurately accommodated in the avoidance opening 126 on the annular limiting seat 1242, making the medicine spraying port 221 of the spray head 220 communicate with the through hole 123. Furthermore, the liquid medicine acts on the user's medication position through the medicine spraying port 221, the through hole 123, the small-diameter port 111, and the large-diameter port 112, realizing positioning administration, standardizing and simplifying the administration process, and improving the accuracy of the administration position. Furthermore, the medicine can better achieve the expected effect.

[0052] In the above embodiment, as Figure 2 and Figure 3As shown, the limiting structure 124 further includes a limiting boss 1241, and the limiting boss 1241 is located at the top of the guide sleeve within the annular limiting seat 1242. In this way, after the spray head 220 is received within the annular limiting seat 1242, the limiting boss 1241 contacts the top of the spray head 220 to limit the axial movement of the spray head 220 along the bottle body 210. Therefore, the force on the spray head 220 can be made uniform, reducing the possibility of the spray head 220 moving, and further improving the accuracy of the drug delivery position.

[0053] In this embodiment, the dual structures of the annular limiting seat 1242 and the limiting boss 1241 are used to position the spray head 220, which can further achieve targeted drug delivery and improve the accuracy of drug delivery.

[0054] Specifically, the limiting boss 1241 can be in surface contact with the spray head 220. For example, the limiting boss 1241 can be fitted to the spray head 220, thereby further improving the uniformity of the force on the spray head 220.

[0055] Such as Figure 4 and Figure 5 As shown, in some possible embodiments provided by the present invention, the side wall 122 of the guide sleeve 120 is formed as the annular limiting seat 1242, and the through hole 123 corresponding to the medicine spraying port 221 on the guide sleeve 120 is formed as the avoidance port 126.

[0056] In this embodiment, the shape of the bottom opening 121 of the guide sleeve 120 is adapted to the shape of the spray head 220. After the spray head 220 of the spray bottle 200 is inserted into the guide sleeve 120 through the opening 121, the opening 121 is located at the position of the spray head 220, that is, the bottle body 210 is not received within the guide sleeve 120. The guide sleeve 120 with this structure is small in volume and material consumption, convenient for storage and conducive to reducing the manufacturing cost.

[0057] It can be understood that in this embodiment, the through hole 123 on the guide sleeve 120 and the avoidance port 126 on the annular limiting seat 1242 can coincide into one structure. The area of the through hole 123 on the side wall 122 of the guide sleeve 120 is smaller than the area of the small-diameter port 111 of the guide cover 110. The small-diameter port 111 of the guide cover 110 covers the outside of the through hole 123 of the guide sleeve 120 and is connected to the side wall 122 of the guide sleeve 120.

[0058] Such as Figure 2 、 Figure 3 、 Figure 8 、 Figure 9 As shown, in some other possible embodiments provided by the present invention, the annular limiting seat 1242 is located within the guide sleeve 120, and the avoidance port 126 is provided at a position corresponding to the through hole 123 of the guide sleeve 120.

[0059] In this embodiment, the avoidance opening 126 on the annular limiting seat 1242 is located inside the guide sleeve 120 relative to the through hole 123 of the guide sleeve 120. The side wall 122 of the guide sleeve 120 is connected to the guide cover 110, and the through hole 123 on the side wall 122 of the guide sleeve 120 is communicated with the small-diameter port 111 of the guide cover 110. The annular limiting seat 1242 inside the guide sleeve 120 is used to limit the spray head 220, and the medicine spraying port 221 of the spray head 220 is accommodated in the avoidance opening 126 of the annular limiting seat 1242. Thus, the connection and fixation of the spray head 220, the guide sleeve 120, and the guide cover 110 can be achieved. With this kind of setting, the structures of the side wall 122 of the guide cover 110 and the annular limiting seat 1242 can be reasonably set respectively to realize the connection between the side wall 122 of the guide cover 110 and the guide sleeve 120, and the connection between the annular limiting seat 1242 and the spray head 220, which is convenient for processing and easy to implement.

[0060] It can be understood that in this embodiment, after the spray bottle 200 is inserted into the guide sleeve 120 through the opening 121, the opening 121 can be located at the position of the bottle body 210, that is, the entire spray head 220 is located inside the guide sleeve. Thus, the guide sleeve 120 has a good protective effect on the entire spray head 220.

[0061] Such as Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, in some possible embodiments provided by the present invention, the guide cover 110 and the guide sleeve 120 are integrally connected structures. That is to say, the drug administration assistance device 100 is set as an integral structure, which simplifies the assembly process, is beneficial to improving production efficiency, and reduces manufacturing costs.

[0062] Furthermore, the drug administration assistance device 100 of the spray bottle 200 further includes a transition portion 130. The transition portion 130 connects the guide cover 110 and the guide sleeve 120. The transition portion 130 is an arc-shaped structure, and the guide cover 110, the guide sleeve 120, and the transition portion 130 are integrally formed structures. Thus, through the arc-shaped transition portion 130 connecting the cylindrical guide sleeve 120 and the conical guide cover 110, the cylindrical guide sleeve 120 and the conical guide cover 110 can be smoothly and evenly transitioned, reducing the occurrence of concentrated stress, which is beneficial to improving the connection reliability between the guide sleeve 120 and the guide cover 110, and further improving the reliability of the drug administration assistance device 100 and extending its service life.

[0063] Further, the guide sleeve 120 includes a top plate 125 opposite to the bottom opening 121, and the top plate 125 is arranged to incline upward along the direction from the guide sleeve 120 to the guide cover 110. Thus, the inclination angle of the top plate 125 of the guide sleeve 120 is adapted to that of the guide cover 110, enabling the arc-shaped transition portion 130 to reliably and stably connect the guide sleeve 120 and the guide cover 110, reducing the occurrence of force concentration, and improving the reliability of the drug delivery assistance device 100.

[0064] As Figure 6 , Figure 7 , Figure 8 and Figure 9 shown, in some other possible embodiments provided by the present invention, the guide cover 110 and the guide sleeve 120 are of a split structure. One of the guide cover 110 and the guide sleeve 120 is provided with a positioning portion, and the other is provided with a limiting portion. The guide cover 110 and the guide sleeve 120 are detachably connected through the positioning portion and the limiting portion.

[0065] Among them, the split guide cover 110 and guide sleeve 120 can replace the guide cover 110 and the guide sleeve 120 respectively, which is beneficial to reducing the use cost. For example, for different users using the same spray bottle 200, the same guide sleeve 120 can be used in combination with different guide covers 110 for drug delivery, which can not only conveniently and standardly achieve accurate drug delivery, but also ensure the hygienic safety of drug delivery, and has a low use cost, being suitable for popularization and application. At the same time, the split guide cover 110 and guide sleeve 120 can be disassembled and then stored, which is beneficial to saving space and facilitating storage.

[0066] Among them, the positioning portion can be arranged on the guide sleeve 120, and the limiting portion can be arranged on the guide cover 110, or the positioning portion can be arranged on the guide cover 110, and the limiting portion can be arranged on the guide sleeve 120 to meet the requirements of different structures of the positioning portion and the limiting portion. Specifically, the positioning portion and the limiting portion can be configured as one of an insertion structure, a snap connection structure, a threaded connection structure, a mortise and tenon structure, and a magnetic attraction structure, which is easy to implement.

[0067] As Figure 6 , Figure 7 and Figure 8 shown, in some possible embodiments provided by the present invention, the positioning portion includes a slot 127 arranged on the side wall 122 of the guide sleeve 120. The socket of the slot 127 is arranged opposite to the opening 121, that is, the socket of the slot 127 faces upward, and the through hole 123 is communicated with the slot 127; the limiting portion includes a plug board 116 arranged on the small-diameter port 111. The small-diameter port 111 penetrates through the plug board 116, and the plug board 116 can be inserted into or detached from the slot 127.

[0068] Thus, when it is necessary to use the drug administration assistance device 100 for drug administration, the insertion plate 116 is inserted into the slot 127 from the upper socket, so as to realize the connection between the guiding cover 110 and the guiding sleeve 120, and it can ensure that the through hole 123 and the medicine inlet 113 are communicated and opposite. Then, the spray bottle 200 is inserted through the opening 121 below the guiding sleeve 120, and the medicine spraying port 221 is aligned with the through hole 123, then the drug administration operation can be carried out, and the liquid medicine is sprayed out through the medicine spraying port 221, the through hole 123, the small-diameter port 111 and the large-diameter port 112.

[0069] After the drug administration is completed, the spray bottle 200 is taken out from below the opening 121, and the insertion plate 116 is moved upward to disengage from the slot 127, so as to realize the disassembly and separation of the guiding cover 110 and the guiding sleeve 120. The operation is simple and the use is convenient.

[0070] For the split-type drug administration assistance device 100 in the above embodiment, as Figure 10 shown, the guiding sleeve 120 can be used alone in cooperation with the spray bottle 200, and the drug administration operation can also be realized, thereby meeting the drug administration operations with relatively low requirements for drug administration accuracy.

[0071] Specifically, as Figure 10 shown, the spray bottle 200 is inserted through the opening 121 below the guiding sleeve 120 so that the spray head 220 is received in the annular limiting seat 1242, the medicine spraying port 221 is received in the avoidance port 126, aligned with the through hole 123, and the through hole 123 is aligned with the user's medication position, then the drug administration operation can be carried out. At this time, the liquid medicine can directly act on the medication position through the medicine spraying port 221 and the through hole 12. In this drug administration method, the guiding sleeve 120 has a simple structure, a beautiful appearance, and is convenient for pressing drug administration, expanding the use range of the drug administration assistance device 100 and realizing multi-functional drug administration operations.

[0072] As Figure 11 and Figure 12 shown, in some possible embodiments provided by the present invention, the edge of the large-diameter port 112 of the guiding cover 110 is provided as an elastic member, that is, the edge part of the large-diameter port 112 is made of an elastic material, and the elastic material can further improve the fitting degree between the large-diameter port 112 and the eye. Specifically, the elastic material can be TPE (Thermoplastic Elastomer), TPU (Thermoplastic polyurethanes), TPR (Thermo-Plastic-Rubber material), etc.

[0073] Among them, the part of the guiding cover 110 except the edge of the large-diameter port 112 can be made of resin, that is, the part of the guiding cover 110 except the edge of the large-diameter port 112 can be made of resin material. The resin material has a low cost, which can save the manufacturing cost. Specifically, the guiding cover 110 can be an injection molded part, which is convenient for processing, can realize mass production, and reduce the manufacturing cost. Further, the guiding cover 110 can be a two-color injection molded part, so that the elastic part of the large-diameter port 112 and the resin parts of other parts are of different colors to increase the comfort of use.

[0074] Specifically, when the drug administration assistance device 100 is of an integral structure, the guiding cover 110 and the guiding sleeve 120 can be integrally formed by a two-color injection molding process. When the drug administration assistance device 100 is of a split structure, the guiding cover 110 can be integrally formed by a two-color injection molding process, and the guiding sleeve 120 can be injection molded. During use, the drug administration assistance device 100 can be disinfected with disinfectants such as alcohol and can be used multiple times to save the use cost.

[0075] Such as Figure 2 、 Figure 4 、 Figure 7 and Figure 12 As shown in

[0076] In some possible embodiments provided by the present invention, the shape of the large-diameter port 112 can match the shape of the drug administration position. For example, when the spray bottle 200 is used for eye drug administration, the shape of the large-diameter port 112 can be oval. In this way, the edge shape of the oval is more in line with the anatomical characteristics of the eye to ensure the fit between the large-diameter port 112 of the guiding cover 110 and the eye, achieve accurate drug administration, and enable the medicament to better achieve the desired effect.
