Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a finger muscle strength detector for patients. Background Technology
[0002] Endotracheal intubation is a method of inserting a specially designed endotracheal tube through the mouth or nose and through the glottis into the trachea or bronchus. It provides the best conditions for airway patency, ventilation and oxygen supply, and airway suction, and is an important measure for rescuing patients with respiratory dysfunction.
[0003] Currently, in clinical practice, when extubating the trachea, it is necessary to test the patient's finger muscle strength to determine whether the characteristics of extubation have been met. The existing testing method is to have the patient hold the nurse's hand, and the nurse feels the strength of the patient's hand to determine whether the characteristics of extubation have been met. However, this method is not accurate in testing hand muscle strength. Therefore, we propose a patient-based finger muscle strength tester to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of the prior art by proposing a finger muscle strength detector for patients.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a finger muscle strength detector for patients, comprising: a shell, an inner cavity, a limiting groove, a first cylinder, a first spring, a mounting ring, a pressure sensor, a second cylinder, a second spring, a pressing seat, a limiting block, a telescopic column, a top rod, a finger groove, a controller, a storage battery, a display screen, a charging port, and scale lines. The inner cavity is fixedly installed inside the shell, and limiting grooves are fixedly installed both above and below the inner cavity. A first cylinder is fixedly installed in the middle left side of the inner cavity, and a first spring is fixedly installed inside the first cylinder. A mounting ring is fixedly installed at the tail end of the first spring, and a pressure sensor is embedded inside the mounting ring. A second cylinder is fixedly installed both above and below the left side of the inner cavity, and the second cylinder is fixedly installed in the middle left side of the inner cavity. A second spring is fixedly installed. A pressing seat is movably installed on the left side inside the inner cavity, and the right side of the pressing seat is located outside the housing. Limiting blocks are fixedly installed on the upper and lower sides of the pressing seat, and the limiting blocks are movably installed inside the limiting grooves. Telescopic columns are fixedly installed on the upper and lower sides of the left side of the pressing seat, and the left side of the telescopic column is fixedly connected to the tail end of the second spring. The telescopic column is slidably connected to the inside of the second cylinder. A top rod is fixedly installed in the middle of the left side of the pressing seat. Multiple finger grooves are fixedly installed on the right side surface of the pressing seat. A controller is fixedly installed on the top of the housing. A battery is fixedly installed inside the housing. A display screen is fixedly installed on the right side of the top of the housing. A charging port is fixedly installed on the bottom of the housing. A scale line is fixedly installed on the top edge of the pressing seat.
[0006] Furthermore, the pressing seat and the inner cavity have a sliding structure, and the push rod corresponds to the pressure sensor.
[0007] Furthermore, the limiting block and the limiting groove have a sliding structure inside.
[0008] Furthermore, four finger slots are provided, and all four finger slots are arranged in an arc shape.
[0009] Furthermore, the scale lines correspond to the top edge of the inner cavity.
[0010] Furthermore, the controller is electrically connected to the display screen, battery, charging port, and pressure sensor.
[0011] Compared with the prior art, this utility model has the following advantages:
[0012] (1) By holding the housing and placing all fingers inside the finger grooves on the pressure seat, and then squeezing the fingers tightly, the pressure seat can move inside the cavity. The pressure seat can simultaneously drive the push rod to move and press the pressure sensor. The greater the pressure of the fingers, the greater the movement of the pressure seat, and the greater the pressure the push rod puts on the pressure sensor. As a result, the pressure-sensitive resistor inside the pressure sensor will deform, thereby changing the resistance value. This can be converted into the corresponding pressure value by the controller, and the pressure value can be displayed in real time on the display screen. At the same time, the movement distance of the pressure seat can also be known through the scale line. Thus, based on the pressure value and the scale line, the specific level of the patient's finger muscle strength can be determined simultaneously, achieving the effect of accurate muscle strength detection.
[0013] (2) The arc-shaped finger groove can match the curvature of the finger, making it easy to exert force when the finger is placed on the pressing seat and less likely to move. Attached Figure Description

[0017] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0018] like Figure 1-2 The illustrated finger muscle strength detector includes: a housing 1, an inner cavity 2, a limiting groove 3, a first cylinder 4, a first spring 5, a mounting ring 6, a pressure sensor 7, a second cylinder 8, a second spring 9, a pressing base 10, a limiting block 11, a telescopic column 12, a push rod 13, a finger groove 14, a controller 15, a battery 16, a display screen 17, a charging port 18, and scale lines 19. The inner cavity 2 is fixedly installed inside the housing 1. Limiting grooves 3 are fixedly installed at both the top and bottom of the inner cavity 2. The first cylinder 4 is fixedly installed in the middle left side of the inner cavity 2. The first spring 5 is fixedly installed inside the first cylinder 4. A mounting ring 6 is fixedly installed at the tail end of the first spring 5, and a pressure sensor 7 is embedded inside the mounting ring 6. The second cylinder 8 is fixedly installed at both the top and bottom left sides of the inner cavity 2. Each of the second cylinder 8 contains a pressure sensor 7. The second spring 9 has a pressing seat 10 movably installed on the left side inside the inner cavity 2, and the right side of the pressing seat 10 is located outside the housing 1. Limiting blocks 11 are fixedly installed on the upper and lower sides of the pressing seat 10, and the limiting blocks 11 are movably installed inside the limiting groove 3. Telescopic columns 12 are fixedly installed on the upper and lower sides of the left side of the pressing seat 10, and the left side of the telescopic column 12 is fixedly connected to the tail end of the second spring 9, and the telescopic column 12 is slidably connected to the inside of the second cylinder 8. A top rod 13 is fixedly installed in the middle of the left side of the pressing seat 10. Multiple finger grooves 14 are fixedly installed on the right surface of the pressing seat 10. A controller 15 is fixedly installed on the top of the housing 1. A battery 16 is fixedly installed inside the housing 1. A display screen 17 is fixedly installed on the right side of the top of the housing 1. A charging port 18 is fixedly installed on the bottom of the housing 1. A scale line 19 is fixedly installed on the top edge of the pressing seat 10.
[0019] In this embodiment, the pressing seat 10 and the inner cavity 2 have a sliding structure, and the push rod 13 corresponds to the pressure sensor 7.
[0020] In practical use, the user holds the housing 1 with their fingers placed on the pressing seat 10 and squeezes it tightly. This allows the pressing seat 10 to move within the inner cavity 2. Simultaneously, the pressing seat 10 drives the telescopic column 12 to move within the second cylinder 8, compressing the second spring 9. The pressing seat 10 also drives the top rod 3 to move, pressing the pressure sensor 7. The greater the pressure applied by the fingers, the greater the movement of the pressing seat 10, and the greater the pressure exerted by the top rod 3 on the pressure sensor 7. This causes deformation of the pressure-sensitive resistor inside the pressure sensor, changing its resistance value. This value is then converted into a corresponding pressure value by the controller 15 and displayed in real-time on the display screen 17. Based on the pressure value, the user can determine the specific level of muscle strength in their fingers, achieving precise muscle strength detection.
[0021] The telescopic column 12 moves inside the second cylinder 8 to compress the second spring 9, so that when the pressing seat 10 is not pressed, the elastic opening of the second spring 9 can drive the pressing seat 10 to return to its original position, thus allowing the muscle strength to continue to be detected.
[0022] The pressure sensor 7 can be moved by the compression of the first spring 5.
[0023] In this embodiment, the limiting block 11 and the limiting groove 3 have a sliding structure inside.
[0024] In practical use, when the pressing seat 10 moves, it can synchronously drive the limiting block 11 to move inside the limiting groove 3, thereby limiting the moving position of the pressing seat 10.
[0025] In this embodiment, four finger slots 14 are provided, and all four finger slots 14 are arranged in an arc shape.
[0026] In practical use, the arc-shaped finger groove 14 can closely match the curvature of the finger, making it easy to apply force when the finger is placed on the pressing seat 10 and preventing it from moving.
[0027] In this embodiment, the scale line 19 corresponds to the top edge of the inner cavity 2.
[0028] In practical use, the scale line 19 corresponds to the top edge of the inner cavity 2, so the movement distance of the pressing seat 10 can be known through the scale line 19. Thus, the specific level of the patient's finger muscle strength can also be determined according to the scale on the scale line 19.
[0029] In this embodiment, the controller 15 is electrically connected to the display screen 17, the battery 16, the charging port 18, and the pressure sensor 7.
[0030] In practical use, the controller 15 can control the working status of the display screen 17, the battery 16, the charging port 18, and the pressure sensor 7. The battery 16 can supply power to the controller 15, the display screen 17, the charging port 18, and the pressure sensor 7. The charging port 18 can charge and store electricity for the battery 16.
[0031] The working principle of a finger muscle strength detector for patients mentioned in this utility model is as follows:
[0032] In use, the user holds the housing 1 and places their fingers inside the finger grooves 14 on the pressure seat 10. Squeezing the pressure seat 10 tightly causes it to move within the inner cavity 2. Simultaneously, the pressure seat 10 moves the telescopic column 12 within the second cylinder 8, compressing the second spring 9. The pressure seat 10 also moves the push rod 3 to press the pressure sensor 7. The greater the pressure applied, the greater the movement of the pressure seat 10, and the greater the pressure exerted by the push rod 3 on the pressure sensor 7. This causes deformation of the pressure-sensitive resistor inside the pressure sensor, changing its resistance value. This change is then converted into a corresponding pressure value by the controller 15, which is displayed in real-time on the display screen 17. The distance the pressure seat moves is also indicated by the scale lines 19. Therefore, based on the pressure value and the scale lines 19, the user can simultaneously determine the specific level of muscle strength in their fingers, achieving precise muscle strength detection.
[0033] At the same time, the telescopic column 12 moves inside the second cylinder 8 to compress the second spring 9, so that after the pressing seat 10 is not pressed, the elastic opening of the second spring 9 can drive the pressing seat 10 to reset, so that muscle strength can continue to be detected.
[0034] At the same time, when the pressing seat 10 moves, it can synchronously drive the limiting block 11 to move inside the limiting groove 3, thereby limiting the moving position of the pressing seat 10.
[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
