Description

Technical Field

[0001] The invention relates to the field of stethoscopes, and in particular to a quick-detachable structure of a diaphragm group for a stethoscope. Background Art

[0002] The diaphragm on the commonly used stethoscope originally adopted a multi-piece design of rim and diaphragm. Every time a new diaphragm is replaced, the gap between the rim and the diaphragm must be carefully sealed for normal use. The more frequent the replacement, the more elastic the rim will become, resulting in an ineffective seal.

[0003] Therefore, practitioners later improved and launched products with integrated diaphragms. For example, U.S. Patent US10213181B2 discloses a stethoscope diaphragm that can effectively reduce the inconvenience of having to carefully confirm whether it is tightly fitted during replacement. In addition, it can also solve the cleaning problem during repeated use.

[0004] Although the above-mentioned improved products have improved the defects of the stethoscopes commonly used in the early days, there are still shortcomings that need to be improved. The disadvantage is that when replacing, due to the structural characteristics of the one-piece diaphragm and the stethoscope body, the elastic material on the side edge of the diaphragm is tightened and further positioned in the groove set in the stethoscope body to form an embedded fixed state, which makes the diaphragm very difficult to disassemble and also increases the time for replacing the diaphragm. Summary of the invention

[0005] The main purpose of the present invention is to provide a quick-release structure of a diaphragm group for a stethoscope, wherein the stethoscope head has two collecting surfaces, each of which can be connected to a diaphragm group integrally formed by an elastic member and a diaphragm, so that the diaphragm group has the advantages of stable connection and convenient disassembly.

[0006] The quick-release structure of the diaphragm group for a stethoscope of the present invention includes: a stethoscope head with two collecting surfaces, which can provide two collecting surfaces for connection with a diaphragm group respectively, wherein an annular embedding groove is recessed at the adjacent outer edge of each collecting surface, and the height of the annular embedding groove is lower than the collecting surface, and a groove is provided on each collecting surface, and the diaphragm group is composed of a diaphragm matched with the inner edge of an elastic member, and the elastic member is provided with a convex rib and a convex portion, and the convex rib is pressed corresponding to the annular embedding groove, and the convex portion is engaged with the groove to further achieve the purpose of embedding and stable connection.

[0007] The annular embedding groove is further provided with an inner side wall, which is arranged in the annular embedding groove and has an inclined design of being wider at the top and narrower at the bottom.

[0008] An inner side surface of the convex rib is also designed as an inclined surface with a narrow upper part and a wide lower part, and is mainly used to cooperate with the inner side wall to be tightly buckled.

[0009] The diaphragm assembly can also be designed as a single elastic member without a diaphragm, and can be used in combination with the elastic member having the diaphragm.

[0010] The elastic member is also provided with an extension portion, which is arranged at the outer edge of the elastic member, and can be pinched by a user to improve the convenience of removing and replacing the diaphragm assembly.

[0011] Through the above technical features, compared with the prior art, the present invention can utilize the annular groove concavely arranged at the outer edge of the collection surface of the stethoscope head and the groove arranged on the collection surface, and further cooperate with a diaphragm group composed of an elastic member and a diaphragm to connect them, forming a quick-release structure of the diaphragm group for the stethoscope, which can effectively improve the inconvenience of disassembly and assembly, and in addition, it has a certain stability and is not easy to fall off.

[0038] Generally, according to the preferred embodiment of the present invention, Figures 1 to 9A detailed description is given to increase understanding of the present invention. The present invention is a quick-release structure of a diaphragm group for a stethoscope. In the embodiment of the present invention, a dual-use stethoscope is used as an explanation, and includes: a stethoscope head (10), which has two collecting surfaces (201, 202). The collecting surfaces (201, 202) can be divided into a large and a small one in detail. The large collecting surface is a first collecting surface (201), and the small collecting surface is a second collecting surface (202). The main difference between them is that they are used on adults and children, and the transmission of high-frequency sounds and low-frequency sounds. In addition, the structures are basically the same, so the following content only uses a single surface for explanation. The aforementioned two collecting surfaces (201, 202) can mainly provide connection with a diaphragm group (30). An annular groove (2011, 202) is recessed at the adjacent outer edges of the collecting surfaces (201, 202). 21), and the height of the annular groove (2011, 2021) is lower than the collecting surface (201, 202), that is, the height of the first collecting surface (201) is higher than the annular groove (2011), and the height of the second collecting surface (202) is higher than the annular groove (2021), and a groove (2013, 2023) is further provided on the collecting surface (201, 202), and the aforementioned diaphragm group (30) is mainly composed of a diaphragm (32) matched at the inner edge of an elastic member (31), and the elastic member (31) is further provided with a convex rib (311) and a convex portion (314), through which the convex rib (311) is pressed respectively corresponding to the annular groove (2011, 2021), and the convex portion (314) is engaged in the groove (2013, 2023) to form a fixed and stable connection.

[0039] Please refer to Figures 3 to 6As shown, the aforementioned annular embedding groove (2011, 2021) further comprises an inner side wall (2012, 2022) disposed in the annular embedding groove (2011, 2021), and the inner side wall (2012, 2022) is designed to be wide at the top and narrow at the bottom, and the annular embedding groove (2011) and the inner side wall (2012) disposed through the first collecting surface (201) can be seen. After the user inserts the diaphragm group (30) at the convex rib (311) of the elastic member (31) into the annular embedding groove (2011), the inner side wall (2012) and the inner side surface (312) are in a mutually embedded and stable connection state, and the convex portion (314) is embedded in the concave groove (2013). As a result, the speed of assembly and connection can be made more stable; and when replacing a new diaphragm group (30), because the inner side surface (312) of the convex rib (311) is also designed as an inclined surface that is narrow at the top and wide at the bottom, it can not only fit tightly with the inner wall (2012), but also be easily disassembled from the reverse side. It is only necessary to directly pinch the elastic part (31) of the diaphragm group (30) by hand, and then it can be directly removed and replaced with a new one, which is simpler and more convenient to use; and an annular embedding groove (2021) is also provided on the second collecting surface (202), and the annular embedding groove (2021) also has an inclined design that is wide at the top and narrow at the bottom. Its structural design and use are the same as the description of the first collecting surface (201) mentioned above, so they will not be repeated.

[0040] Please refer to Figures 7-8 As shown in the figure, the outer edge of the elastic member (31) is further provided with an extension portion (313). When the extension portion (313) is provided at the outer edge, it can be slightly adjusted in position so that the user can reduce the foreign body sensation when using the stethoscope head (10). Its main function is to provide a larger contact area for the user's hand when the user holds the stethoscope head (10) with the hand, so that the user can easily apply force to detach the elastic member (31) from the connected state of the stethoscope head (10), thereby improving the convenience and speed of replacing the diaphragm group (30). The extension portion (313) can be designed into different shapes and sizes according to needs to correspond to the disassembly force of different user hand sizes, and is not limited to this.

[0041] Please see again Fig. 9 As shown in the figure, the diaphragm group (30) located on the second collection surface (202) can also be replaced with a single elastic member (31) without a diaphragm design, and can be used in conjunction with the elastic member (31) with a diaphragm (32) installed on the first collection surface (201). Further coordination mainly depends on the design purpose of the stethoscope head (10) and there is no mandatory restriction.

[0042] In summary, the present invention is a quick-release structure for a diaphragm assembly of a stethoscope, which mainly uses the annular embedding grooves (2011, 2021) of each collecting surface (201, 202) and the inner side walls (2012, 2022) with inclined angles provided on the annular embedding grooves (2011, 2021) to allow the elastic member (31) with the same inclined surface design to utilize the wide and narrow design, so that the two can achieve a stable embedding during assembly and can also maintain the convenience of ease when disassembling in the reverse direction.
