Technical Field

[0001] The utility model relates to the field of medical equipment shells, in particular to a waterproof electrocardiograph shell. Background Art

[0002] An electrocardiograph is a medical electronic device that detects and records the electrocardiogram signals generated by the myocardium during cardiac activity. It can assist doctors in making accurate diagnoses of patients' conditions. A common electrocardiograph consists of an outer casing, electronic components inside the casing, and electrodes that can be attached to the patient's body surface. The device is often placed in a ward or operating room depending on the usage scenario.

[0003] After the use of the ECG machine is completed, medical staff need to take the machine out of the operating room or ward and clean and disinfect its surface to prevent the germs carried by the patient from infecting subsequent patients. However, in the subsequent cleaning process, since the surface of the ECG machine is equipped with heat dissipation vents for blowing out internal heat and ports for external power cords or signal cables, there is a possibility of water or disinfectant liquid entering the heat dissipation vents or wiring ports during the cleaning process or when placed in the ward, there is a certain risk of use.

[0034] See also Figure 1-5 The present application discloses a waterproof electrocardiograph housing, comprising a housing body 1 of the electrocardiograph and a waterproof sealing component 2 arranged on the surface of the housing body 1.

[0035] Among them, the surface of the common electrocardiograph housing body 1 is provided with openings for access of power lines and signal lines and heat dissipation, which can allow external power lines and signal line connectors to be inserted into the electrocardiograph.

[0036] The waterproof sealing component 2 includes a movable sealing portion 21 arranged on the surface of the shell body 1, and a fixing portion 22 capable of fixing the movable sealing portion 21 on the surface of the shell body 1. After being subjected to the overall weight pressure of the shell body 1, the sealing portion can seal the opening on the surface of the shell body 1, and continue to seal the interface after cleaning to prevent liquid from entering the interface or heat dissipation port due to accidents during the storage of the electrocardiograph, thereby ensuring the service life of the electrocardiograph in the more complex environment of the hospital.

[0037] Specifically, the sealing portion includes a sealing piece 211 that can seal the opening on the surface of the shell body 1, and a slot 212 arranged on the surface of the shell body 1 for the sealing piece 211 to be inserted. The sealing piece 211 can be a plate-like structure. At the same time, the opening of the slot 212 faces the bottom of the shell body 1, so as to ensure that the sealing piece 211 can enter the slot 212 under the pressure from the entire shell body 1, so as to facilitate subsequent use by medical staff.

[0038] Taking into account the smooth access of external power supply and electrical signal lines, a socket is provided inside the slot 212 for inserting the power line and / or the electrical signal line into the opening. The internal midline of the socket is perpendicular to the internal midline of the slot 212. After the connector is installed in the interface, the sealing member 211 can be supported, thereby fixing the sealing member 211.

[0039] Since the surface of the electrocardiograph is provided with a plurality of openings and interfaces, the number of the blocking members 211 should correspond to the number of interfaces on the surface of the electrocardiograph. The number of the blocking members 211 is at least one, preferably two, which can shield the side of the electrocardiograph. Adjacent blocking members 211 are connected by connecting members 214. The connecting members 214 can be a plate-shaped structure, and the connecting members 214 and the blocking members 211 can be perpendicular to each other. Figure 3 As shown, it is possible to ensure that the blocking piece 211 can move smoothly inside the slot 212 while allowing the blocking pieces 211 to be stably connected to each other.

[0040] Since some heat dissipation openings are located at the bottom of the instrument, a sealing pad corresponding to the heat dissipation opening can also be provided on the connecting piece (214) to ensure that the heat dissipation opening is sealed to prevent water stains or other medical liquids from entering.

[0041] At the same time, the fixing part 22 includes a fixing part 221 arranged inside the socket, and a movable limiting part 222 connecting the fixing part 221 and the shell body 1, and the movable limiting part 222 can limit the fixing part 221 from moving out of the socket from the inside to the outside of the socket. The fixing part 221 can be a frame-like structure, and a through opening for inserting a power cord and / or an electrical signal line into the opening is provided on the surface of the fixing part 221, thereby ensuring that the fixing part 221 supports the blocking part 211 instead of the power cord connector.

[0042] To ensure that the fixing member 221 limits the position of the blocking member 211, a slot matching the fixing member 221 is provided on the surface of the blocking member 211. After the blocking member 211 is fully inserted into the slot 212, the fixing member 221 entering the socket can be inserted into the slot on the blocking member 211.

[0043] In some embodiments, to facilitate the resetting and movement of the fixing member 221, an elastic connecting member 223 is provided between the movable limiting member 222 and the shell body 1. The elastic connecting member 223 can be a structure such as a spring. When the elastic connecting member 223 is not subjected to pressure, it can pull the fixing member 221 into the slot on the blocking member 211.

[0044] A limiting structure 213 is provided between the blocking member 211 and the slot 212 to limit the blocking member 211 from sliding out of the slot 212 . As shown in the figure, the limiting structure 213 may be composed of a slider and a slide groove to prevent the blocking member 211 from sliding off.

[0045] In the description of this technology, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this technology can be understood according to specific circumstances.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
