Description

Technical Field

[0001] The present invention relates to the field of auxiliary rehabilitation equipment, and in particular to an auxiliary recovery device for bone trauma. Background Art

[0002] The grip strength rehabilitation device is mainly used for patients with hemiplegia and hand movement disorders caused by neurological damage, or patients who need rehabilitation exercises after surgeries such as breast lymph node dissection and deep vein catheterization. The device maintains the function of the patient's hand muscles by repeatedly grasping the grip strength rehabilitation ball.

[0003] Most grip strength rehabilitation devices are grip balls, which use the elasticity of the grip balls to form a pressing resistance to assist grip strength training. However, the pressing resistance formed by existing grip elastic balls is consistent and single (mainly determined by the material of the grip elastic balls themselves), and the pressing resistance cannot be adjusted according to the patient's recovery level.

[0004] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention

[0005] In view of the above-mentioned defects, the purpose of the present invention is to provide an auxiliary recovery device for bone trauma, which can adjust the pressing resistance by adjusting the opening degree of the air port, and through an independently arranged one-way valve, it does not affect the use of the equipment and can quickly reset the equipment.

[0006] In order to achieve the above-mentioned purpose, the present invention provides an auxiliary recovery device for bone trauma, comprising an elastic reset member with a cavity arranged inside; a one-way valve and a flow regulating valve are arranged at a predetermined position on the outer wall of the elastic reset member; when the elastic reset member is pressed once, the fluid originally stored inside it flows to the outside through the flow regulating valve; when the elastic reset member is reset, the external fluid enters the chamber through the one-way valve.

[0007] According to the auxiliary recovery device for bone trauma of the present invention, the elastic reset member is a spherical or ellipsoidal structure.

[0008] According to the auxiliary recovery device for bone trauma of the present invention, the outer wall of the elastic reset member has a supporting texture extending along the alignment direction.

[0009] According to the auxiliary recovery device for bone trauma of the present invention, an elastic metal strip for assisting the elastic resetting member in resetting is arranged inside the supporting texture.

[0010] According to the auxiliary recovery device for bone trauma of the present invention, the flow regulating valve includes a first valve body fitting and a second valve body fitting which are threadedly connected to each other; the first valve body fitting has an air port; and the second valve body fitting includes a baffle for adjusting the opening degree of the air port.

[0011] According to the auxiliary recovery device for bone trauma of the present invention, the one-way valve includes a valve body with an opening, a blocking member located at the opening and capable of blocking the opening, and an elastic member connecting the blocking member and the valve body.

[0012] The present invention provides an auxiliary recovery device for bone trauma, including an elastic reset member with a cavity inside; the elastic reset member is made of elastic material and can be reset to the initial state after appropriate pressing, so that the entire palm can fit with the device of the present application during the pressing process, that is, the fitting surface when the palm is pressed is increased, and the auxiliary recovery effect of the device is optimized. A one-way valve and a flow regulating valve are arranged at a predetermined position on the outer wall of the elastic reset member; when the elastic reset member is pressed once, the fluid originally stored inside it flows to the outside through the flow regulating valve; at this time, the one-way valve is one-way cut-off, and when the fluid passes through the flow regulating valve, the flow regulating valve is used to prevent the fluid from being released quickly, so that when the elastic reset member is pressed, the internal gas generates a pressure of pressing resistance. When the elastic reset member is reset, the external fluid enters the chamber through the one-way valve. At this time, the resistance of the fluid passing through the one-way valve is much smaller than the resistance of the fluid passing through the flow regulating valve, so that the external fluid will preferentially enter the elastic reset member through the one-way valve to reset it quickly. The present invention can adjust the pressing resistance by adjusting the opening degree of the air port, and through the independently arranged one-way valve, it does not affect the use of the device and can quickly reset the device.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] See also Figure 1 , Figure 2 and Figure 4 The present invention provides an auxiliary recovery device for bone trauma, which includes an elastic reset member 1 with a cavity inside; the elastic reset member 1 is made of elastic material (elastic rubber can be), and can be reset to an initial state after appropriate pressing. In this embodiment, in order to make the entire palm fit with the device of the present application during the pressing process, that is, to increase the fitting surface when the palm is pressed, the auxiliary recovery effect of the equipment is optimized.

[0022] A one-way valve 2 and a flow regulating valve 3 are provided at predetermined positions on the outer wall of the elastic reset member 1;

[0023] When the elastic return member 1 is pressed once, the fluid (air) originally stored inside it flows to the outside through the flow regulating valve 3; at this time, the one-way valve 2 is one-way cutoff, and when the fluid passes through the flow regulating valve 3, the flow regulating valve 3 is used to prevent the fluid from being released quickly, so that when the elastic return member 1 is pressed, the internal gas generates air pressure that produces pressing resistance.

[0024] When the elastic reset member 1 is reset, the external fluid enters the chamber through the one-way valve 2. It needs to be further explained that at this time, the resistance of the fluid passing through the one-way valve 2 is much smaller than the resistance of the fluid passing through the flow regulating valve 3. Therefore, the external fluid will preferentially enter the elastic reset member 1 through the one-way valve 2 to enable it to reset quickly.

[0025] See also Figure 6 The specific structure of the one-way valve 2 includes a valve body 61 with an opening, a blocking member 62 (a blocking ball can be used) located at the opening and capable of blocking the opening, and an elastic member 63 (a spring can be used) connecting the blocking member 62 and the valve body 61. When the one-way is cut off (when the device is pressed), the blocking member 62 blocks the opening. When the one-way is conducted (air is taken into the device), the elastic reset member 1 is deformed and reset so that the negative pressure inside it drives the airflow to push the blocking member 62 away from the opening, and the opening is conducted.

[0026] See also Figure 1 and Figure 2 Preferably, the outer wall of the elastic reset member 1 extends along the aligning direction with a support texture 4. The support texture 4 can increase the friction between the palm and the device when the device is in use, and prevent the device from falling out when pressed.

[0027] See also Figure 2 and Figure 3In addition, an elastic metal strip 5 is provided inside the supporting texture 4 to assist the elastic reset member 1 in resetting. The elastic metal strip 5 can be made of memory metal. The elastic metal strip 5 can increase the pressing resistance of the elastic reset member 1 to a certain extent, and optimize the elastic reset effect of the elastic reset member 1.

[0028] See also Figure 2 and Figure 5 The flow regulating valve 3 includes a first valve body fitting 51 and a second valve body fitting 52 which are threadedly connected to each other; the first valve body fitting 51 has a screw hole, and the second valve body fitting 52 is correspondingly provided with a matching threaded connection part (screw), and the relative movement of the first valve body fitting 51 and the second valve body fitting 52 is driven by the threaded connection structure.

[0029] The first valve body fitting 51 has an air port 511. During the pressing process of the device, the air flow in its cavity is discharged through the air port 511, and the size of the air port 511 determines the pressing resistance generated when the elastic reset member 1 is pressed, that is, the larger the air port 511, the smaller the pressing resistance fed back when the device is pressed, and conversely, the smaller the air port 511, the greater the pressing resistance fed back when the device is pressed.

[0030] The second valve body fitting 52 includes a baffle 521 for adjusting the opening degree of the gas port 511 . The first valve body fitting 51 and the second valve body fitting 52 move relative to each other to drive the baffle 521 to adjust the opening degree of the gas port 511 .

[0031] In summary, the present invention provides an auxiliary recovery device for bone trauma, including an elastic reset member with a cavity inside; the elastic reset member is made of elastic material and can be reset to the initial state after appropriate pressing, so that the entire palm can fit with the device of the present application during the pressing process, that is, the fitting surface when the palm is pressed is increased, and the auxiliary recovery effect of the device is optimized. A one-way valve and a flow regulating valve are arranged at a predetermined position on the outer wall of the elastic reset member; when the elastic reset member is pressed once, the fluid originally stored inside it flows to the outside through the flow regulating valve; at this time, the one-way valve is one-way cutoff, and when the fluid passes through the flow regulating valve, the flow regulating valve is used to prevent the fluid from being released quickly, so that when the elastic reset member is pressed, the internal gas generates a pressure of pressing resistance. When the elastic reset member is reset, the external fluid enters the chamber through the one-way valve. At this time, the resistance of the fluid passing through the one-way valve is much smaller than the resistance of the fluid passing through the flow regulating valve, so that the external fluid will preferentially enter the elastic reset member through the one-way valve to reset it quickly. The present invention can adjust the pressing resistance by adjusting the opening degree of the air port, and through the independently arranged one-way valve, it does not affect the use of the device and can quickly reset the device.

[0032] Of course, the present invention may have many other embodiments.
