The invention relates to a pressure measuring device configured to surround a subject's body part. It comprises a pressure application element configured to apply pressure to the body part, a pressure sensing device configured to measure a pressure signal of the subject and a shell (4) which is arranged to be located between the pressure application element and the body part. The shell is curled to a conical or cylindrical configuration and comprises an elastic liner (93) arranged inside of the curled shell, wherein, if the pressure measuring device does not surround the body part, there is free space in between the liner (93) and the inner surface of the shell (4). This allows to reduce the likelihood of wrinkles of the liner and thus of pressure marks on the skin of the body part caused by wrinkles, wherein still the pressure measuring device is usable with different diameters.

Personalized adaptation of the body contour of the patient can be achieved, meanwhile, repeated utilization can be achieved, disposable consumables do not need to be replaced, the medical cost is greatly reduced, medical waste pollution is reduced, operation is convenient and fast, body position fixing and repeated calling can be rapidly completed, and radiotherapy accuracy, patient comfort and radiotherapy turnover efficiency are improved to a certain degree.

This invention belongs to the field of refractive surgery simulation technology and discloses a VR-based immersive simulation system for refractive surgery procedures. It supports patients inputting refractive parameters such as myopia and astigmatism via VR controllers or voice input, while also incorporating biomechanical data such as corneal elastic modulus and thickness distribution. Built-in parameter verification logic ensures accurate input. Utilizing a model that fuses B-spline curves with corneal biomechanical parameters, it can adjust key surgical data such as laser scanning path and microlens thickness in real time based on patient parameters. Through preset personalized plans, patients can switch between and compare the scanning effects of different plans, perceive surgical details adapted to their own eye conditions, and establish an understanding of the targeted nature and safety of the surgery. The VR headset's eye mask integrates a micro-vibration motor, air pump, and heating pad to replicate the pressure sensation during real surgery.

To provide a massager that utilizes cross reciprocating motion of a movable member. The device comprises an outer shell 1, a drive unit 2 (mounted within the outer shell), a transmission assembly 3 (mounted within the outer shell and connected to the drive unit), and multiple movable members 4 (connected to the transmission assembly and capable of reciprocating motion). The drive unit functions as a power source, rotating the transmission assembly, and the movable members convert the rotational motion into vertically intersecting reciprocating motion. This eliminates the monotonous vibration rhythm and stiff pressure sensations found in conventional massage devices, resulting in localized overpressure and insufficient stimulation. The alternating massage provides smooth changes in force, providing multi-layered stimulation and significantly improving comfort, meeting the needs of a variety of users.

Next, at least one of the vibration, displacement, and deformation of the object body is displayed. A sense synthesizing and inducing device synthesizes the sensibility of inducing sensing, and generates at least one of contact force sense, kinesthetic sense, and illusion by displacement that gives sweep displacement to the object body.SELECTED DRAWING: Figure 8

The invention relates to a pressure measuring device configured to surround a subject's body part. It comprises a pressure application element configured to apply pressure to the body part and a shell 4 which is arranged to be located between the pressure application element and the body part. It comprises a pressure sensing device with a fluid-filled pressure sensing pad inside the shell, a pressure transducer outside of the shell and a fluid-filled tube 62. The shell comprises an opening, through which the tube is fed for allowing the tube to transmit pressure from the pressure sensing pad to the pressure transducer outside of the shell. The shell comprises a tube housing 101 on the outside surface of the shell and at the location of the opening. The tube housing can reduce the likelihood of a pressure signal loss and of pressure marks on the skin of the body part.

[Problem] To provide a training machine in which a back pad is locally in contact with the back, thereby making it easy to be aware of the orientation or position of the trunk via skin sensation or pressure sensation and in which a user performs postural control, thereby making it easy to maintain a trunk-extended position. [Solution] Provided is a training machine for performing training while being seated with the trunk substantially perpendicular to the floor surface, said training machine comprising a back pad which is capable of locally pressing the back in a seated state. A user performs postural control such that the back pad is always fitted to the back, thereby making it easy to maintain a trunk-extended position. Stretching of core muscles around the scapula required to exert physiologically large energy is effectively facilitated. The pad is in contact with the back, thereby making it possible to have a function such as an indicator which makes it easy to be aware of the orientation or position of the trunk via skin sensation or pressure sensation, and making it possible to further promote learning of how to use the trunk part.

A virtual tactile device is provided, which includes a display terminal and a wearable device that receives information about a position, a shape, and a physical property of an object displayed on the display screen, and the user's finger position. In one example, the wearable device includes a micro-displacement stimulation element that is in close contact with the user's finger skin. When the finger wearing the wearable device contacts an object displayed on the display screen or moves on the screen of the display terminal, the micro-displacement stimulation element applies a micro-displacement stimulus to the finger skin, selectively triggering action potentials of multiple tactile receptors in the skin. In coordination with the display terminal's screen, the system can provide tactile feedback, including protruding pressure sensations, curvature, and friction textures.
