Description
Technical Field
The present application relates to the field of medical technology. In particular, the present application relates to a medical device having an electrically conductive viewing window.
Background
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
Medical devices need to follow EMC (electromagnetic compatibility) test standards to ensure proper or accurate operation of the medical device without causing electromagnetic interference in its proper operating environment. The housing of the medical device is typically provided with a transparent window for viewing, which is made of a transparent but non-conductive material such as plastic or glass. For EMC testing, the transparent window should be electrically conductive.
In some medical devices, a conductive material is coated over the transparent window. However, due to the smaller range of applications, the cost of these medical devices is higher and the supply chain lead time is longer.
In other medical devices, the conductive film is bonded to the transparent window by an adhesive. In order to obtain high quality adhesives, complex process control is required using dedicated equipment. Therefore, these medical devices are costly and difficult to implement.
Disclosure of Invention
Technical problem
As described above, the existing conductive transparent window of the medical device is complicated in processing process, long in production period, high in cost, and/or requires special equipment, etc.
The present application proposes a medical device which is capable of solving at least one of the above-mentioned problems. In particular, the present application proposes a medical device capable of satisfying electromagnetic compatibility (EMC) detection requirements, while being capable of simplifying manufacturing processes, shortening manufacturing cycles, and/or reducing costs.
Technical proposal
According to one aspect of the present disclosure, a medical device is provided that includes a housing and a transparent window disposed on the housing. The transparent window includes a first viewing portion. The first viewing portion includes a first non-conductive layer, a conductive layer, and a second non-conductive layer, wherein the conductive layer is sandwiched and secured between the first non-conductive layer and the second non-conductive layer.
In some embodiments, the first non-conductive layer, the conductive layer, and the second non-conductive layer are fastened together by a first fastener.
In some embodiments, the conductive layer has ground tabs on opposite sides. The first non-conductive layer has a connection tab corresponding to the ground tab. The grounding tab is connected to the housing by a metal connection via the connection tab.
In some embodiments, the metal connector is a screw. The grounding lug and the connecting lug are provided with through holes for receiving the screws. The housing is provided with a threaded bore engaging the screw.
In some embodiments, the first viewing portion is secured to the housing by a second fastener.
In some embodiments, the first fastener and the second fastener are the same fastener.
In some embodiments, the conductive layer is formed of a conductive film.
In some embodiments, the conductive film is an indium tin oxide film or a silver laminate film.
In some embodiments, the transparent window further comprises a second viewing portion, the second viewing portion being located on one side of the first viewing portion.
In some embodiments, the second viewing portion is formed of a single non-conductive layer or has the same structure as the first viewing portion.
In some embodiments, the second viewing portion is located at a top surface of the housing and the first viewing portion is located at a front surface of the housing.
Technical effects
According to the medical device of the present application, the transparent window is a sandwich structure, i.e. two non-conductive layers sandwich and fix one conductive layer between them. Such a sandwich structure can be easily fastened together mechanically (e.g. fasteners such as screws) without any adhesive and without a coating process. Obviously, the assembly process of the sandwich structure is greatly simplified, the implementation is very easy, the production period is shortened, and the cost is reduced.
The design of the sandwich structure is very flexible, e.g. a conductive layer may be provided with tabs for grounding. The grounding tabs make electrical connection and installation easier. Likewise, the ground tab may also be easily mounted to the housing of the medical device by fasteners such as screws.
The conductive layer may be formed of a conductive film. For example, a conductive film commercially available at present can be used. This can significantly reduce the processing cycle time and reduce costs. The conductive film commercially available at present is, for example, an indium tin oxide film (Indium Tin Oxide film, abbreviated as ITO film) or a silver laminated film (Ag-deposited film). The indium tin oxide thin film and the silver laminated thin film have high transmittance, low resistance and good flexibility, and thus can satisfy EMC requirements.
The transparent window includes a first viewing portion and a second viewing portion that facilitate viewing from different viewing angles of the medical device. The positions and structures of the first observation portion and the second observation portion may be changed as needed, and thus may be adapted to various demands.
Further areas of applicability will become apparent from the description provided herein. It should be understood that the particular examples and embodiments described in this section are for illustrative purposes only and are not intended to limit the scope of the present disclosure.

A medical device 10 according to an embodiment of the present disclosure will be described below with reference to fig. 1 and 2. It should be understood that the medical device 10 shown in the figures is for illustrative purposes only and should not be limited to the specific structures shown in the figures.
As shown in fig. 1 and 2, the medical device 10 includes a housing 110 and a transparent window 130 disposed on the housing 110.
The housing 110 constitutes an external appearance of the medical device 10 and defines an internal operation space or accommodation space. The housing 110 generally has a generally rectangular parallelepiped shape including a front surface 111 facing the user, a rear surface 112 opposite the front surface 111, a top surface 113, a bottom surface 114 opposite the top surface 113, and a side surface 115 between the front surface 111 and the rear surface 112. It should be appreciated that the various surfaces of the housing 110 are named with respect to the user's orientation, and that the various surfaces of the housing 110 are not necessarily integral, continuous surfaces.
The transparent window 130 is configured to facilitate a user's observation of the inner space defined by the housing 110, and is conductive for EMC testing. In the example shown in fig. 1 and 2, the transparent window 130 includes a first viewing portion 130a and a second viewing portion 130b. The second observation portion 130b is on the upper side of the first observation portion 130a. The first observation portion 130a is located at the front surface 111 of the housing 110 to observe the inner space of the housing 110 from the front. The second viewing portion 130b is located at the top surface 113 of the housing 110 so as to view the inner space of the housing 110 from above.
It should be understood that the number of viewing portions of the transparent window is not limited to two as shown in the drawings, but may be changed as needed, for example, may have one viewing portion, three or more viewing portions. Further, the position of the observation portion of the transparent window is not limited to the example shown in the drawings, but may be changed as needed.
A transparent window 130 according to an embodiment of the present disclosure will be described with reference to fig. 3.
As shown in fig. 3, the first observation portion 130a includes a first non-conductive layer 131, a conductive layer 132, and a second non-conductive layer 133. The conductive layer 132 is sandwiched and fastened between the first non-conductive layer 131 and the second non-conductive layer 133.
The first non-conductive layer 131, the conductive layer 132, and the second non-conductive layer 133 have a substantially rectangular plate-like structure, and are stacked in order. However, it should be understood that the shapes of the first non-conductive layer 131, the conductive layer 132, and the second non-conductive layer 133 may vary according to the shape of the opening on the case 110, and are not necessarily limited to the specific examples shown in the drawings.
The first, conductive and second non-conductive layers 131, 132 and 133 are provided with holes 131a, 132a and 133a, respectively, for receiving fasteners 140. For example, the fastener 140 may be a screw. The first non-conductive layer 131, the conductive layer 132, and the second non-conductive layer 133 are fastened together by inserting fasteners 140. The holes 131a, 132a, and 133a may be disposed along edges of the first non-conductive layer 131, the conductive layer 132, and the second non-conductive layer 133. In an example not shown, the first non-conductive layer 131, the conductive layer 132, and the second non-conductive layer 133 may be provided with flanges (not shown) extending from edges, and the holes 131a, 132a, and 133a are provided on the flanges.
The fastener 140 may be coupled to a threaded hole (not shown) of the housing 110, thereby fastening the first viewing portion 130a to the housing 110. It should be appreciated that the first viewing portion 130a may also be secured to the housing 110 by other fasteners.
It should be appreciated that the first non-conductive layer 131, the conductive layer 132, and the second non-conductive layer 133 may be fastened together in any other suitable manner without being limited to the screws shown in the figures.
The conductive layer 132 has ground tabs 142 on opposite sides. The first non-conductive layer 131 is adjacent to the housing 110 and has connection tabs 141 corresponding to the ground tabs 142, respectively. The ground tab 142 and the connection tab 141 are provided with through holes 131b and 132b, respectively, for receiving the metal connector 150. For example, the metal connection 150 is a screw. The metal connector 150 may have a larger size than the fastener 140 to ensure electrical connection. The metal connector 150 is inserted through the through holes 131b and 132b and then connected to a screw hole (not shown) of the housing 110. In this way, the ground tab 142 is connected to the housing 110 via the connection tab 141.
The ground tab 142 is not connected to the second non-conductive layer 133. Thus, the second non-conductive layer 133 may not have a connection tab disposed thereon. The second non-conductive layer 133 is located inside compared to the first non-conductive layer 131.
The two ground tabs 142 may have the same shape and size, or may have different shapes and sizes as desired. The positions of the two ground tabs 142 may be set as desired and need not be limited to the specific examples shown in the figures. Accordingly, the structure and position of the connection tab 141 may be varied as desired and need not be limited to the specific examples shown in the figures.
The structure of the metal connector 150 is not necessarily limited to the specific example shown in the drawings as long as the functions described herein can be achieved.
The first and second non-conductive layers 131 and 133 may be made of a non-conductive transparent material, for example, plastic or glass, etc. For example, the first and second non-conductive layers 131 and 133 may be made of an acrylic plate.
The conductive layer 132 may be formed of a conductive film. The conductive film may be any suitable conductive film currently commercially available. Preferably, the conductive film has high transmittance, low resistance, and the like suitable for EMC testing and assembly. For example, the conductive film may be an indium tin oxide film (ITO film) or a silver-Stacked film (Ag-Stacked film).
It should be understood that the structure of the first observation portion 130a and the respective layers 131 to 133 thereof may be changed as needed, and is not necessarily limited to the specific example shown in the drawings.
The first viewing portion according to the present application has a sandwich structure or a sandwich structure. The structure integrates transparency, conductivity and higher strength, and can meet the functional and performance requirements of products. The structure is also convenient to assemble and disassemble, and is beneficial to maintainability of products. The first viewing portion does not require an adhesive or coating process, so that the manufacturing process and the assembly process are significantly simplified, the product lead time is shortened, and the cost is reduced.
In the example shown in fig. 3, the second observation portion 130b has a different structure from the first observation portion 130a. As shown in fig. 3, the second observation portion 130b is formed of a single non-conductive layer 171. However, it should be understood that the second observation portion 130b may have the same structure as the first observation portion 131a, i.e., a sandwich structure, as desired.
The shape of the second observation portion 130b may be determined according to the opening of the case 110 and the shape of the first observation portion 130a. Thus, it is understood that the shape of the second observation portion 130b should not be limited to the specific example shown in the drawings.
Similar to the first viewing portion 130a, the second viewing portion 130b may also be connected to the housing 110 and/or the first viewing portion 130a by fasteners (not shown), such as screws. In alternative examples, the second viewing portion 130b may also be connected to the housing 110 and/or the first viewing portion 130a by any other suitable means.
The non-conductive layer 171 of the second viewing portion 130b may be made of a non-conductive transparent material, such as plastic or glass, for example. For example, the non-conductive layer 171 may be made of an acrylic plate.
Various embodiments and variations of the present disclosure have been specifically described above, but it will be understood by those skilled in the art that the present disclosure is not limited to the specific embodiments and variations described above but may include other various possible combinations and combinations. Other modifications and variations can be effected by those of skill in the art without departing from the spirit and scope of the disclosure.
