Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a breast MR examination pad that prevents hand numbness. Background Technology
[0002] During breast MRI examinations, the examination time is relatively long, and the patient is required to lie prone with their arms extended forward for an extended period of time. This can easily cause numbness in the patient's hands, affecting the comfort of the examination and even the image quality. Utility Model Content
[0003] To address the aforementioned problems, the purpose of this invention is to provide a breast MR examination pad that prevents hand numbness, allowing the patient to grip an elastic ball to alleviate numbness in both hands as much as possible.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A breast MR examination pad for preventing hand numbness includes an examination pad assembly, a counterweight assembly located below the front end of the examination pad assembly, and a pair of hand training components located on the left and right sides above the examination pad assembly, with their lower parts passing through the sides of the examination pad assembly and fixed to the counterweight assembly. The examination pad assembly includes a base pad laid on an examination bed and a C-shaped elastic boss fixed around the front end of the base pad. The counterweight assembly includes a mounting base fixed to the lower part of the C-shaped elastic boss, a load-bearing rope movably passing through the mounting base in the middle, and load-bearing blocks fixed at both ends of the load-bearing rope. The C-shaped elastic boss is provided with a pair of arm placement slots. Each set of hand training components includes an elastic grip ball that is engaged in the corresponding arm placement slot and a connecting rope with one end fixed to the elastic grip ball and the other end passing through the C-shaped elastic boss and fixed to the load-bearing block.
[0006] More preferably, the C-shaped elastic protrusion is further provided with an alarm component; the alarm component includes an elastic rope fixed to the C-shaped elastic protrusion, an elastic ball fixed to the movable end of the elastic rope and having a pressure sensor inside, and an alarm fixed to the C-shaped elastic protrusion and electrically connected to the pressure sensor.
[0007] More preferably, the upper surface of the C-shaped elastic protrusion is symmetrically provided with arm placement slots on both sides to accommodate the patient's arm; two elastic grip balls are respectively placed at the front end of each arm placement slot.
[0008] Even better, each arm placement slot has several elastic massage points spaced apart on its inner wall.
[0009] This utility model has the following beneficial effects:
[0010] 1. When the patient is in a prone position for testing, the patient holds two elastic grip balls with both hands and then releases them. The patient's hand muscles exert force and relax, which promotes blood flow in the hand and improves the numbness caused by the patient's hands being stretched forward for a long time. This improves the comfort of the examination and minimizes the impact on image quality caused by arm numbness and slow blood flow.
[0011] 2. After the patient's examination is completed, under the gravitational pull of the load-bearing block, the elastic grip ball will be pulled to the arm placement slot by the connecting rope that is movably threaded through the C-shaped elastic protrusion, thereby realizing the storage of the elastic grip ball. Through this specially designed inertial automatic storage structure, on the one hand, it can avoid the situation where the patient accidentally presses on the elastic grip ball due to improper placement when using the examination pad. On the other hand, by fixing the elastic grip ball with the connecting rope, it can avoid the loss of the elastic grip ball as much as possible. At the same time, the position of the elastic grip ball can be adaptively adjusted to avoid the situation where some patients have short arms and cannot hold the elastic grip ball.

Detailed Implementation
[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0017] A breast MR examination pad for preventing hand numbness includes an examination pad assembly 1, a counterweight assembly 2 located below the front end of the examination pad assembly 1, and a pair of hand training components 3 respectively located on the left and right sides above the examination pad assembly 1, with their lower parts passing through the sides of the examination pad assembly 1 and fixed to the counterweight assembly 2. The examination pad assembly 1 includes a base pad 11 laid on the examination bed and a C-shaped elastic boss 12 surrounding and fixed to the front end of the base pad 11. The counterweight assembly 2 includes a mounting base 21 fixed to the lower part of the C-shaped elastic boss 12, a load-bearing rope 22 movably passing through the mounting base 21 in the middle, and load-bearing blocks 23 fixed to both ends of the load-bearing rope 22. The C-shaped elastic boss 12 is provided with a pair of arm placement slots 121. Each set of hand training components 3 includes an elastic grip ball 31 locked in the corresponding arm placement slot 121 and a connecting rope 32 with one end fixed to the elastic grip ball 31 and the other end passing through the C-shaped elastic boss 12 and fixed to the load-bearing block 23.
[0018] While the patient remains prone during the examination, both hands grip and release the two elastic grip balls 31. This action of contracting and relaxing the patient's hand muscles promotes blood flow in the hands, alleviating numbness caused by prolonged forward extension of the hands. This improves comfort during the examination and minimizes the impact on image quality caused by numbness and slow blood flow. After the examination, under the gravitational pull of the weight block 23, the elastic grip balls 31 are movably pulled by the connecting rope 32 threaded on the C-shaped elastic protrusion 12. Pull the elastic grip ball 31 to the arm placement slot 121 to store it. This specially designed inertial automatic storage structure minimizes the risk of patients accidentally pressing on the elastic grip ball 31 due to improper placement. Furthermore, the connecting rope 32 secures the elastic grip ball 31, preventing its loss. The position of the elastic grip ball 31 can also be adjusted to accommodate patients with shorter arms who cannot grip it.
[0019] As a possible implementation of this solution, preferably, the C-shaped elastic protrusion 12 is further provided with an alarm component 4; the alarm component 4 includes an elastic rope 41 fixed to the C-shaped elastic protrusion 12, an elastic ball 42 fixed to the movable end of the elastic rope 41 and having a pressure sensor inside, and an alarm 43 fixed to the C-shaped elastic protrusion 12 and electrically connected to the pressure sensor; when the patient is unwell, by holding the elastic ball 42, the pressure sensor inside the elastic ball 42 will feel the pressure, at which time the alarm 43 will be activated to sound an alarm to alert medical staff that the patient is unwell.
[0020] As a possible implementation of this solution, preferably, a plurality of elastic massage points 122 are spaced apart on the inner sidewall of each arm placement slot 121; by setting the elastic massage points 122, the arm can be massaged by applying different pressures to the elastic massage points 122 when the patient holds the elastic grip ball 31, depending on whether the arm muscles exert force or relax, thereby further increasing the patient's comfort level during the test.
[0021] The working principle of this device is as follows:
[0022] When using this device, first place the examination pad at the front of the examination bed, then the patient lies face down on the examination bed. After adjusting the patient's position, place the patient's arms in the two arm placement slots 121 respectively, and place the two elastic grip balls 31 in the patient's hands respectively, so that the patient can relieve numbness in the hands by holding the elastic grip balls 31 during the test. When the patient feels uncomfortable, he / she can release the elastic grip balls 31 and then clench the elastic ball 42. When the pressure sensor in the elastic ball 42 senses the pressure, the alarm 43 will sound an alarm to alert medical staff that the patient has uncomfortable symptoms.
[0023] The above description is only a specific embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
