Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and more specifically, to a waterproof structure of a defibrillator. Background Art

[0002] Currently, more and more public places such as airports, train stations, and schools are equipped with defibrillators. Because some defibrillators are kept outdoors in playgrounds and other places, it is recommended to set up a defibrillator safe and store the defibrillator inside to prevent water accumulation from affecting the internal components during rainy and snowy weather. Although the safe deposit box can prevent liquid erosion caused by rain and snow, in cities with large temperature differences between morning and evening or high humidity, frost, dew, and fogging may occur inside the safe deposit box. Although physical dehumidification can be achieved by installing a desiccant inside the safe deposit box, if the desiccant is not replaced in a timely manner, it is still difficult to prevent moisture in the fog from entering the defibrillator casing through the seams.

[0003] The moisture infiltration caused by the above-mentioned routine storage belongs to the usage scenario that can be controlled manually. However, when using the defibrillator, the use environment is an uncontrollable factor. There may be accumulated water on site, or it may be used in rainy or snowy weather. At this time, once the internal electrical components of the defibrillator short-circuit, the impact will be very serious. Therefore, the shell of the defibrillator needs to have good sealing to cope with the risks of rust and short-circuit caused by daily storage, as well as the short-circuit risks caused by diversified usage scenarios.

[0004] Patent application number 202220744169.8 discloses a seal with an elastic sealing portion at the joint. The seal can indeed achieve sealing through its own elasticity, but because an additional elastic structure needs to be added to the joint, the volume of the device after production is larger than that of a traditional portable defibrillator. In addition, the production process and processing precision requirements for the shell are higher than those of traditional defibrillators, resulting in high production costs. In addition, a large part of the elastic sealing portion is exposed on the shell, so when it is transported after production is completed, it is easy to produce a flanging (the part that fits the outer wall of the shell is turned over). Therefore, how to further optimize the sealing of the defibrillator joint is a technical problem to be solved by the present invention. Utility Model Content

[0005] The Summary of the Utility Model introduces a series of simplified concepts that will be further described in the Detailed Description of the Utility Model.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0028] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0029] like Figures 1-6 As shown, the utility model provides a waterproof structure of a defibrillator, comprising: a first shell 1 and a second shell 2 that are detachably connected and used for setting the waterproof structure of the defibrillator. The first shell 1 and the second shell 2 together constitute the shell of the defibrillator. A defibrillator module necessary for the defibrillator is arranged in the shell, and necessary structures such as a socket for connecting the defibrillator module to an electrode assembly, a physical button, and a display screen are provided on the shell. The necessary structures for realizing the basic functions of the defibrillator mentioned above are all commercially available products or existing technologies. A first seal is provided on the portion of the first shell 1 for docking with the second shell 2, and a second seal is provided on the portion of the second shell 2 for docking with the first shell 1. The first seal and the second seal are both provided on the end faces of the shell edges, so that when the first shell 1 and the second shell 2 are docked, the first seal can be connected to the second seal, and there is no need to deliberately connect the first seal and the second seal. During the docking process, the first seal and the second seal will naturally connect together, which will not affect the smoothness of the operation when the first shell 1 and the second shell 2 are docked, and the operating steps when the defibrillator is assembled will be reduced. After the first shell 1 and the second shell 2 are docked, the first seal and the second seal can seal the connection between the first shell 1 and the second shell 2, thereby achieving dust-proof and waterproof effects. Because the first shell 1 and the second shell 2 are made of insulating materials, they can also have the effect of preventing leakage.

[0030] In this embodiment, we provide a specific implementation of the first sealing member and the second sealing member. The first sealing member is a sealing protrusion 3 provided along the portion of the first shell 1 for docking with the second shell 2. The sealing protrusion 3 is located on the end surface of the portion of the first shell 1 for docking with the second shell 2. Figure 2 、 5 As shown, the second sealing member is a sealing groove 4 provided along the portion of the second shell 2 for docking with the first shell 1. The sealing groove 4 is located on the end surface of the portion of the second shell 2 for docking with the first shell 1. Figure 3 、 6 As shown, when the first shell 1 and the second shell 2 are butted together, the sealing groove 4 is plugged into the sealing protrusion 3. The sealing protrusion 3 and the sealing groove 4 can both be formed in one step when the first shell 1 and the second shell 2 are manufactured. Because the first shell 1 and the second shell 2 are both formed in one step through a mold, the dimensional accuracy of the sealing protrusion 3 and the sealing groove 4 can be well guaranteed during mass production. According to design requirements, the sealing protrusion 3 and the sealing groove 4 can be an interference fit or a clearance fit (the size of the gap needs to be limited so that the liquid does not enter the interior of the shell under the action of tension). According to the different ways of fitting the two, the following various different implementation methods will be derived.

[0031] The first shell 1 is provided with at least four shell edges, and the second shell 2 is provided with at least four shell edges. When the sealing protrusion 3 and the sealing groove 4 adopt a clearance fit, the assembly of the first shell 1 and the second shell 2 is more convenient than the interference fit. A pressure plate 5 is provided on one of the shell edges of the first shell 1. A rubber pad for support can be provided at the bottom of the pressure plate 5. The pressure plate 5 is usually provided on the shell edge at the bottom when the defibrillator is placed vertically, such as Figure 1The pressure plate 5 extends toward the second shell 2. A pressure plate groove 6 is provided on one side of the second shell 2. The shape of the pressure plate groove 6 is adapted to the shape and position of the pressure plate 5. To ensure sealing after connection, a sealing protrusion 3 can be provided on the pressure plate 5, and a sealing groove 4 can be provided on the pressure plate groove 6. The sealing protrusions 3 and sealing grooves 4 of the first shell 1 and the second shell 2 are integrated into one. When the first shell 1 and the second shell 2 are docked together, the pressure plate 5 presses on the pressure plate groove 6, so that when the defibrillator is placed vertically, the pressure plate 5 can have a larger abutment surface. By providing a protruding rubber pad on the pressure plate 5, the upward support force of the defibrillator can act on the pressure plate 5. In addition, by installing different necessary structures on the first shell 1 and the second shell 2 respectively within the shell, the weight of the two is inconsistent, thereby causing a certain difference in the vertical force acting on the first shell 1 and the second shell 2. As a result, when the defibrillator is placed vertically, the first shell 1 and the second shell 2 will be misaligned due to the different forces, thereby compensating the gap between the sealing protrusion 3 and the sealing groove 4, thereby improving the sealing performance when using a clearance fit. When the defibrillator is placed horizontally during use, because the structures within the shell are installed on the first shell 1 and the second shell 2 respectively, under the action of gravity, the first shell 1 will also press on the second shell 2, thereby improving the sealing performance after the two are connected. If the first shell 1 and the second shell 2 are further connected by screws on the basis of the first seal and the second seal, the sealing of the connection between the two can be adjusted by tightening the screws, and the clearance fit setting makes it easier to assemble and disassemble the first shell 1 and the second shell 2.

[0032] Furthermore, a third sealing member 7 is provided in the pressure plate groove 6. When the first shell 1 and the second shell 2 are docked, the pressure plate 5 is connected to the pressure plate groove 6 through the third sealing member 7. Figure 4 、 5 As shown, the third seal 7 is elastic. When the first shell 1 and the second shell 2 are mated, the pressure plate 5 and the pressure plate groove 6 squeeze the third seal 7. By providing the third seal 7, after the first shell 1 is mated with the second shell 2, the elastic force of the third seal 7 can cause the assembled first and second shells 1 and 2 to misalign, thereby closing the gap and maintaining the mating state before screwing, facilitating screwing. Furthermore, if the third seal 7 is provided, the corresponding sealing protrusion 3 and sealing groove 4 on the pressure plate 5 and pressure plate groove 6 can be eliminated. When installing the first and second shells 1 and 2, the pressure plate groove 6 and pressure plate 5 can be used as the entry point. Instead of vertical installation along the sealing groove 4 in the previous embodiment, installation can be adjusted to an angled installation, further facilitating installation of the first and second shells 1 and 2. The third seal 7 also ensures a tight seal between the pressure plate 5 and the pressure plate groove 6. The third seal 7 can be directly adhered to the pressure plate groove 6.

[0033] The pressure plate 5 is provided with a first limiting member 8 extending in the direction of the pressure plate groove 6. When the first shell 1 and the second shell 2 are docked together, the third sealing member 7 is located between the first limiting member 8 and the side wall of the pressure plate groove 6. It is used to limit the third sealing member 7. In order to avoid the pressure plate 5 from deforming the third sealing member 7 during long-term use, thereby causing sealing problems, a second limiting member 9 can be provided in the pressure plate groove 6. The second limiting member 9 is provided along the inner side wall of the pressure plate groove 6. When the first shell 1 and the second shell 2 are docked together, the third sealing member 7 is located between the first limiting member 8 and the second limiting member 9. The third sealing member 7 is elastic. When the first shell 1 and the second shell 2 are docked together, the first limiting member 8 and the second limiting member 9 squeeze the third sealing member 7. The pressure plate 5 and the pressure plate groove 6 also squeeze the third sealing member 7. Figure 5 As shown, by limiting the third sealing member 7 in four directions, after the first shell 1 and the second shell 2 are docked, the elastic action of the third sealing member 7 can maintain the docking state of the first shell 1 and the second shell 2, making it convenient to tighten the screws for assembly of the shell.

[0034] When the sealing protrusion 3 and the sealing groove 4 are in an interference fit, a first groove 10 is provided on the second shell 2. The first groove 10 is provided along the outer wall of the pressure plate groove 6 and is in communication with the pressure plate groove 6. A second groove 11 is provided on the portion of the first shell 1 that is used to interface with the second shell 2. The second groove 11 is provided along the outer wall of the portion of the first shell 1 that is used to interface with the second shell 2 and is in communication with the end face of the portion of the first shell 1 that is used to interface with the second shell 2. As a result, after the first shell 1 and the second shell 2 are connected, a corresponding groove is left at the joint position. Because an interference fit is more troublesome during disassembly, a corresponding groove is reserved to facilitate disassembly along the joint. It should be noted that this embodiment can also be applied to a clearance fit. External liquid will first accumulate in the first groove 10 and the second groove 11. Under the action of liquid tension, the gap and groove are blocked to prevent subsequent liquid infiltration.

[0035] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation to the present invention.

[0036] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified.
