Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a sensor component. Background Art

[0002] The TCM pulse data acquisition system is a device for collecting human pulse information, mainly used for TCM diagnosis and treatment. It can sense changes in human pulse through sensors and transmit these data to a computer or mobile device for analysis and processing, such as a TCM pulse data acquisition device disclosed in Chinese patent document CN209074584U. The collected pulse data can help TCM doctors understand the patient's physical condition, diagnose diseases, and develop personalized treatment plans.

[0003] The pulse diagnosis arm is an indispensable part of the pulse data collection system of traditional Chinese medicine. The sensor is usually arranged at the end of the pulse diagnosis arm to collect human pulse data. The pulse diagnosis arm is provided with a plurality of swinging or rotating parts to adjust the posture of the pulse diagnosis arm. When in use, the patient's arm is placed on the examination table, and the pulse diagnosis arm is pressed down to make the sensor touch the pulse collection part of the arm. After finding the position, the sensor is pushed down by the power mechanism in the pulse diagnosis arm to form a certain pressure between the sensor and the patient's pulse. For example, the applicant's prior patent CN 219846554U discloses a sensor assembly and a pulse diagnosis arm, which drives the sensor to move up and down by a motor, and controls the rotation angle of the motor to accurately control the lifting stroke of the sensor, thereby realizing the adjustable pressure between the sensor and the patient's skin.

[0004] However, this technical solution still has the following problems: because the sensor and the force transmission block are plug-in connected, and the radial movement of the force transmission block is not completely restricted, when in use, the soft rubber head may be impacted by radial force due to movement of the patient's wrist or impact of other external forces, and the force may be transmitted to the sensor through the force transmission block, causing the sensor to be impacted by radial force, which may easily cause damage to the sensor.

By providing a force transmission rod and a guide seat that are in sliding fit along the axial direction, the radial displacement of the force transmission rod is limited, and the top surface of the force transmission rod is in surface contact with the bottom surface of the sensor, which completely eliminates the radial force of the force transmission rod on the sensor, avoids damage to the sensor caused by the impact of radial force, and improves the service life of the sensor assembly.

[0008] Preferably, a protective sheath made of flexible material is provided on the surface of the sensor module to enhance protection.

[0009] Preferably, the sheath is provided with a threading notch for threading the connecting wire of the sensor.

[0010] Preferably, the sensor base is provided with a threading opening for threading the connecting wire of the sensor.

[0011] Preferably, the telescopic end of the telescopic motor is threadedly connected to the sensor base, and the sensor module can be pre-assembled as a whole and then threadedly connected to the telescopic end of the telescopic motor, which is convenient for assembly and later maintenance and replacement.

[0012] Preferably, the telescopic end of the telescopic motor is connected to the sensor base by a hexagon socket bolt, and the hexagon socket bolt passes upward from the sensor base. With such an arrangement, during installation, the sensor base is first fixed to the telescopic end of the telescopic motor with the hexagon socket bolt, and then the sensor, force transmission rod, guide seat and other parts are installed. This can ensure that the position of the threading opening is consistent when fixing the sensor base, which is beneficial to subsequent assembly work.

[0013] Preferably, a pressure block is connected to the lower end of the force transmission rod.

[0014] Preferably, the pressing block is inserted into a soft rubber head.

[0015] Preferably, the force transmission rod is a stepped shaft, and the radial cross-section of the top stepped portion thereof is non-circular, so as to avoid the force transmission rod rotating after being subjected to torque and transmitting the torque to the sensor during pulse diagnosis.

[0016] Preferably, the force transmission rod is a stepped rod, and the radial cross-section of the slidingly matched portion between the force transmission rod and the guide seat is non-circular, so as to avoid the force transmission rod rotating after receiving torque and transmitting the torque to the sensor during pulse diagnosis.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The utility model limits the radial displacement of the force transmission rod by arranging a force transmission rod and a guide seat that slide together along the axial direction, and the top surface of the force transmission rod is in surface contact with the bottom surface of the sensor, which completely eliminates the radial force of the force transmission rod on the sensor, avoids damage to the sensor caused by the impact of radial force, and improves the service life of the sensor assembly.
