When the patient uses it, it cannot better assist the patient in rehabilitation training. UTILITY MODEL CONTENT
[0004] To solve the above technical problems, the utility model provides a PICC catheterization training with grip ball, which can detect the intensity and number of grip training of the patient, and better assist the patient in rehabilitation training to achieve the best recovery effect. The technical scheme adopted is as follows:
[0005] A kind of grip ball for PICC catheterization training, including grip ball body, the finger sleeve is fixedly connected to the outer surface of grip ball body, the pressure receiving platform is fixedly connected to the surface of grip ball body, characterized by: the front surface of the pressure receiving platform is fixedly connected with display screen;The inner wall of the grip ball body is fixedly connected with pressure spring, the inner wall of the grip ball body is fixedly connected with contact column, the inner wall of the grip ball body is fixedly connected with limit post, the first connecting plate is sleeved on the surface of limit post, the left end of the first connecting plate is fixedly connected with contact sensor, the right end of the first connecting plate is fixedly connected with first buffer spring, the inner wall of the grip ball body is fixedly connected with pressing column, the inner wall of the grip ball body is fixedly connected with limit sleeve, the second connecting plate is slidably connected in the limit sleeve, the left end of the second connecting plate is fixedly connected with pressure sensor, the right end of the second connecting plate is fixedly connected with second buffer spring;The contact sensor, the pressure sensor are electrically connected with the circuit of the display screen.
[0006] When the PICC catheter training handgrip ball is used, the patient can hold the handgrip ball in the palm of the hand, and place the thumb on the pressure platform, and the remaining four fingers are inserted into the finger sleeve. By pressing the handgrip ball, the pressing column is brought into contact with the pressure sensor, the strength of the patient's handgrip training is detected by the pressure sensor, and is sent to the display screen for display. At the same time, the contact column is brought into contact with the contact sensor and then separated. One contact separation represents one use of the handgrip. The number of contact separations is sent to the display screen by the contact sensor for recording, and the counting function is realized. When the patient uses the handgrip, the PICC catheter training handgrip ball can detect the strength and number of each handgrip training of the patient, and the user can intuitively understand the handgrip training situation, such as the size of the handgrip, and better assist the patient in rehabilitation training to achieve the best recovery effect. Moreover, the doctor can study the influence of different handgrip degrees of the patient on catheter-related thrombosis from the handgrip training situation of the patient.
[0007] Generally, the display screen is internally provided with a controller, and the contact sensor and the pressure sensor are electrically connected to corresponding input ends of the controller through lines of the display screen. In use, the contact sensor and the pressure sensor can transmit the collected data to the controller in real time for statistics, analysis and processing, and the size of the handgrip and the number of exercises are converted into numerical values and displayed on the display screen in real time.
[0008] As a preferred scheme of the utility model, the finger sleeve and the pressure platform are evenly distributed at two ends with the handgrip ball front center as the symmetry center. The material of the handgrip ball is rubber. By evenly distributing the finger sleeve and the pressure platform at two ends with the handgrip ball front center as the symmetry center, the force distribution is more uniform when the user holds the handgrip ball for training. Moreover, the material of the handgrip ball is rubber, and the rubber has good elasticity. On the one hand, the rubber can provide appropriate reaction force when being extruded, simulating the hand feeling in actual operation. On the other hand, the rubber material is relatively soft, and the user feels comfortable when holding the handgrip ball, and the hand is not easily injured.
[0009] As a preferred scheme of the utility model, the number of pressure springs is two, and the two pressure springs are evenly distributed at the inside with the handgrip ball front center as the symmetry center. The contact column is connected at the center of the first connecting plate. By adopting this structure, the two pressure springs are evenly distributed at the inside with the handgrip ball front center as the symmetry center. The symmetrical distribution helps to provide uniform elastic support when the handgrip ball is extruded, so that the handgrip measurement is more accurate. At the same time, the contact column and the first connecting plate are concentric. This design can ensure the accuracy of pressure transmission, so that the pressure received by the contact column can be effectively transmitted to the first connecting plate and the components connected thereto, thereby improving the accuracy of the entire structure for handgrip detection.
[0010] As the preferred scheme of the utility model, the number of the limiting column is two, and the two limiting columns are evenly distributed in the inside in the center of the front face of the first connecting plate. The symmetrical distribution helps to provide uniform elastic support when the grip ball is pressed, and the movement of the contact column and the contact sensor is more stable.
[0011] As the preferred scheme of the utility model, the pressing column is concentrically arranged with the limiting sleeve.
[0012] Compared with the prior art, the utility model has the beneficial effects as follows:
[0013] The grip ball for PICC catheterization training can detect the strength and frequency of each grip training of the patient when the patient uses the grip strengthener, and better assists the patient in rehabilitation training to achieve the best recovery effect. BRIEF DESCRIPTION OF DRAWINGS
