Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a portable medical testing box. Background Technology

[0002] In the existing technology, the prevention and detection of temporomandibular joint disorder requires the use of a temporomandibular joint detection system to simulate relevant joint vibration signals.

[0003] For example, the background technology of patent application CN117814753A proposes that: Existing detection systems for monitoring and detecting jaw disc displacement and wear consist of a wearable single-axis accelerometer, a microphone, a data acquisition card, a timer, a computer detection platform, and a computer processing platform. The test subject wears the wearable single-axis accelerometer at both ends of the test point on the face. The accelerometer and microphone are connected to the NI data acquisition card via a coaxial cable connector (BNC connector). The AD signal conversion module converts the received analog signal into a digital signal that the computer can process, and transmits it to the computer via a square connector cable. The computer processing platform first receives the digital signal after conversion by the AD signal converter, processes the digital signal to obtain its characteristic quantities, and ultimately uses them to assess the degree of jaw disc displacement and wear.

[0004] Patent application CN119548167A discloses a temporomandibular joint health monitoring system based on joint vibration information, including a touch-sensitive sensor, a microcontroller, and an interactive display terminal. The system collects three-dimensional joint vibration simulation signals through an accelerometer in the touch-sensitive sensor and converts them into digital signals.

[0005] The aforementioned prior art describes the structure and detection principle of a temporomandibular joint (TMJ) testing system. However, since these systems are typically located in examination rooms within medical institutions, they generally do not require relocation; the patient enters the examination room for the necessary tests. In areas with limited medical resources and no dedicated TMJ examination room, a portable testing device capable of detecting TMJ vibration sounds is needed to provide timely testing services to patients.

A cooling fan is provided on the rear wall to dissipate heat from the containment space.

[0010] Furthermore, the front wall is provided with a slot that faces and communicates with the paper output port of the printer.

[0011] Furthermore, the lower housing is provided with filter screens on both side walls that connect the lower housing to the outside world. The filter screens are located on both side walls of the lower housing near the printer.

[0012] Furthermore, the printer is detachably connected to the lower housing.

[0013] Furthermore, the hinge is a damping hinge, used to steplessly adjust the opening size between the upper and lower housings.

[0014] Furthermore, the sensor includes a headband and accelerometers located at both ends of the headband.

[0015] Beneficial Effects: The portable temporomandibular joint vibration sound detection box provided by this utility model adopts an openable box design. The lower box serves as a base, integrating an industrial control computer, power supply, data acquisition card, printer, and a storage box for storing the sound sensor, which are essential detection components in existing temporomandibular joint detection systems. A display screen is installed on the inner side of the upper box, which faces upwards towards the user when opened for easy viewing of the displayed information.

[0019] Figure 4 A 3D view of the printer locking mechanism. Detailed Implementation

[0020] Please see Figure 1 and Figure 2 As shown, this utility model provides a portable temporomandibular joint vibration sound detection box, including an upper box 1, a lower box 2 connected to the upper box 1 by a hinge 3, an upper box protective shell 4, and a lower box protective shell 5. A display screen 6 is provided on the inner side of the upper box 1. A recessed storage space is formed in the lower box 2, containing a data acquisition system located at the bottom, a storage box 7 placed on the data acquisition system, and a printer 8 located beside the data acquisition system and the storage box 7. In this embodiment, the hinge 3 is a damping hinge, used to infinitely adjust the opening size between the upper box 1 and the lower box 2, facilitating the user to adjust the angle of observation of the display screen 6. After the upper box 1 and the lower box 2 are closed, they are locked by a box buckle 501, and a handle 502 is provided on the lower box protective shell 5 to facilitate the user's carrying of the locked upper box 1 and lower box 2.

[0021] The data acquisition system includes a first cover 9, an industrial computer 10, a power supply 11, and a data acquisition card 12. The first cover 9 has a top surface and side walls. The industrial computer 10, power supply 11, and data acquisition card 12 are fixedly installed at the bottom of the receiving space. The first cover 9 covers the industrial computer 10, power supply 11, and data acquisition card 12. The storage box 7 is placed on the top surface of the first cover 9, and a sensor 13 is provided in the storage box 7. The lower housing 2 includes a bottom wall, a front wall 201, a rear wall 202, and two side walls 203. The industrial computer 10 is located near the rear wall 202, and the printer 8 is located near the front wall 201. A cooling fan 14 is provided on the rear wall 202 to dissipate heat from the receiving space. Filter covers 204 connecting the lower housing 2 to the outside are provided on the two side walls 203, and the filter covers 204 are located on the two side walls 203 near the printer 8. The cooling fan 14, the internal space of the lower housing 2, and the filter screen 204 form a heat dissipation airflow channel: When the portable temporomandibular joint vibration sound detection box is powered on, the air blown into the lower housing 2 by the cooling fan 14 carries away the heat inside the lower housing 2 from back to front and is blown out from the filter screen, cooling the various electronic components inside the lower housing 2. A slot 204 is provided on the front wall 201, which faces the paper output port of the printer 8 and communicates with the paper output port, so that the paper printed by the printer 8 can be directly output from the slot 204.

[0022] Please combine Figure 2 and Figure 4 As shown, the printer 8 is covered by a second cover 15, and the printer 8 is detachably connected to the lower housing 2. Specifically, the lower housing 2 has printer locking components 16 on both sides of the printer 8. The printer locking components 16 include a support member 1601 fixed to the bottom wall of the lower housing 2, a locking plate 1602 located on top of the support member 1601, and a wing nut 1603 connecting the support member 1601 and the locking plate 1602. The locking plate 1602 extends outward from its connection with the support member 1601 and presses against the printer 8, fixing the printer 8 inside the lower housing 2. When the printer 8 needs to have its paper replaced, the second cover 15 can be removed, the wing nut 1603 can be loosened, and the locking plate 1602 can be rotated at a certain angle to disengage from the printer 8, allowing the printer 8 to be removed from the lower housing 2 for paper replacement.

[0023] like Figure 3 As shown, the sensor 13 includes a headband 1301 and accelerometers 1302 located at both ends of the headband 1301. In this embodiment, the accelerometer 1302 is a SENTHER 510A-100-M model, with a measurement range of 100G peak value and a sensitivity of 50mV / g (±10%). The accelerometer 1302 is connected to the data acquisition card 12 via a BCN connector. The data acquisition card 12 is a VK700 model, an isolated USB high-speed 24-bit data acquisition card, which can be connected to the industrial control computer 10 via USB for power supply and data transmission. This portable temporomandibular joint vibration sound detection box can be carried by medical workers. When testing is required, the portable temporomandibular joint vibration sound detection box is powered on, the upper box 1 is opened, and the sensor 13 is taken out from the storage box 7 for the subject to wear, thus enabling the detection of temporomandibular joint vibration sounds. This portable temporomandibular joint vibration sound detection box is suitable for use in scenarios where medical conditions are limited and there is no independent temporomandibular joint examination room.
