Massage device for preventing venous thrombosis

Abstract

This utility model relates to a massage device, and more particularly to a massage device for preventing venous thrombosis, comprising a first support frame, a housing, an airbag, an air pump, and a blocking component. Two symmetrical housings are slidably mounted on the top of the first support frame. At least two airbags are arranged side-by-side on one side of the housings, close to each other. An air pump is located on the side of the housing facing away from the airbags. The airbags are connected to the air pump's outlet, and a blocking component is provided between the airbags and the air pump's outlet to block their connection. Driven by an electric slide rail, the wedge block moves forward along the electric slide rail, its inclined surface pressing against the extrusion rod. This causes the connecting plate and the baffle connected to the connecting plate to move upward. The baffle then contacts the communication channel between the air pump's outlet and the airbag, allowing the air pump to inject gas into the airbag and inflate it.

Description

Technical Field

[0001] This utility model relates to a massage device, and more particularly to a massage device for preventing venous thrombosis. Background Technology

[0002] Massage devices for preventing venous thrombosis are devices that physically stimulate muscles and blood vessels to help improve blood circulation and reduce the risk of venous thrombosis. These devices primarily promote blood flow by mimicking the natural contraction and relaxation of muscles, thereby reducing the likelihood of blood pooling and thrombus formation.

[0003] Most existing massage devices have pre-set control programs that control different massage blocks to come into contact with the body in order to relax muscles, relieve pain, and promote blood circulation. However, after prolonged use, if the built-in program of an electric massage device malfunctions, the device will not function properly, thus affecting the patient's experience.

[0004] Therefore, it is necessary to design a massage device with a low failure rate to prevent venous thrombosis. Utility Model Content

[0005] The technical solution of this utility model is as follows: a massage device for preventing venous thrombosis, comprising a first support frame, a housing, an airbag, an air pump, a blocking component, a driving component, and a squeezing component. Two symmetrical housings are slidably arranged on the top of the first support frame. At least two airbags are arranged side by side on one side of the housings that are close to each other. An air pump is arranged on the side of the housing that faces away from the airbags. The airbags are connected to the air outlet of the air pump. A blocking component is arranged between the airbags and the air outlet of the air pump to block their connection. A driving component is arranged on the first support frame to drive the two housings to move closer or further apart. A squeezing component is arranged on the housing to release the blocking function of the blocking component, thereby connecting the airbags and the air pump.

[0006] As a preferred technical solution of this utility model, the drive assembly includes a second support frame, a motor, a threaded rod and a first slider. The first slider is connected to the bottom of the housing, and a threaded rod is threadedly connected between the two first sliders. The two ends of the threaded rod are rotatably connected to the second support frame, and the threaded rod is connected to the output shaft of the motor mounted on the second support frame.

[0007] As a preferred technical solution of this utility model, the blocking component includes a first guide rod, a baffle, a second guide rod, a connecting plate, a second slider, and a spring. At least two first guide rods are arranged side by side on the top of the box. A connecting plate is slidably connected to the first guide rod. A spring is provided between the connecting plate and the bottom of the box. The spring is wound around the first guide rod. A baffle is connected to the bottom of the connecting plate. The baffle vertically penetrates the box and is used to block the communication channel between the airbag and the air pump. A second slider is connected to the side of the baffle facing away from the airbag. The second slider is slidably connected to the second guide rod, which is arranged side by side in the inner cavity of the box.

[0008] As a preferred technical solution of this utility model, the extrusion assembly includes a wedge block, an electric slide rail and an extrusion rod. An electric slide rail is provided on the top of the box, and a wedge block is slidably connected on the electric slide rail. The wedge block is extruded and engaged with the extrusion rod provided on one side of the connecting plate.

[0009] As a preferred technical solution of this utility model, a reset groove is provided on the side of the wedge block facing the extrusion rod, and the lowest point of the reset groove near the inclined surface of the wedge block is lower than the height of the extrusion rod.

[0010] As a preferred technical solution of this utility model, it also includes protective cotton, and protective cotton is provided at the arc-shaped notch of the box.

[0011] Beneficial effects: Driven by the electric slide rail, the wedge block moves forward along the electric slide rail, and its inclined surface squeezes the extrusion rods. This causes the connecting plate and the baffle connected to the connecting plate to move upward. The baffle moves upward and contacts the communication channel between the air pump outlet and the airbag. The air pump can then inject gas into the airbag, causing the airbag to inflate. As the wedge block moves horizontally along the electric slide rail, the inclined surface of the wedge block squeezes different extrusion rods from back to front, thereby realizing the sequential inflation of the airbag from back to front. The inflation of the airbag achieves the function of massaging the patient's lower limbs from back to front. This device does not require additional control programs and has the advantages of being simple to use and having a low failure rate. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0019] Example: A massage device for preventing venous thrombosis, such as Figure 1 As shown, the device includes a first support frame 1, a housing 2, airbags 3, an air pump 4, a blocking component, a driving component, and a squeezing component. Two symmetrical housings 2 are slidably mounted on the top of the first support frame 1. The side of the housings 2 that is close to each other is designed with an arc shape to accommodate the user's lower limbs. Protective cotton 8 is provided at the arc-shaped notch of the housing 2 to prevent the patient's lower limbs from directly contacting the housing 2. Eight airbags 3 are arranged side by side on the side of the housings 2 that is close to each other. An air pump 4 is provided on the side of the housing 2 that is away from the airbags 3. The airbags 3 are connected to the air outlet of the air pump 4, and the air pump 4 inflates the airbags 3. A blocking component is provided between the airbags 3 and the air outlet of the air pump 4 to block their connection. A driving component is provided on the first support frame 1 to drive the two housings 2 to move closer or further apart. A squeezing component is provided on the housing 2 to release the blocking function of the blocking component, thereby allowing the airbags 3 to connect with the air pump 4.

[0020] like Figure 1 and Figure 2 As shown, the driving assembly includes a second support frame 101, a motor 5, a threaded rod 501, and a first slider 502. The bottom of the housing 2 is connected to the first slider 502, and the first slider 502 at the bottom of two adjacent housings 2 are threadedly connected to the threaded rod 501. The two ends of the threaded rod 501 are rotatably connected to the second support frame 101. The threaded rod 501 is connected to the output shaft of the motor 5 mounted on the second support frame 101. The motor 5 drives the threaded rod 501 to rotate, thereby causing the two first sliders 502 on the threaded rod 501 to move closer or further apart, so that the two housings 2 move closer or further apart, thereby adjusting the distance between the two housings 2 according to the thickness of the patient's lower limb.

[0021] like Figure 3 and Figure 4As shown, the blocking assembly includes a first guide rod 6, a baffle 601, a second guide rod 602, a connecting plate 603, a second slider 604, and a spring 605. Eight n-shaped first guide rods 6 are arranged side-by-side on the top of the housing 2. A connecting plate 603 is slidably connected to each first guide rod 6. A spring 605 is installed between the connecting plate 603 and the bottom of the housing 2. The spring 605 is wound around the first guide rods 6, and its two ends are connected to the connecting plate 603 and the housing 2, respectively. A baffle 601 is connected to the bottom of the connecting plate 603 and penetrates vertically through the housing 2. The baffle 601 is used to block the airbag 3. The communication channel between the air pump 4 and the baffle 601 is connected to a second slider 604 on the side of the baffle 601 facing away from the airbag 3. The second slider 604 is slidably connected to a second guide rod 602 that is arranged parallel to it in the inner cavity of the housing 2. The connecting plate 603 moves up and down along the first guide rod 6. When the connecting plate 603 moves up and down, it drives the baffle 601 to move up and down. When the baffle 601 rises, the baffle 601 moves away from the communication channel between the airbag 3 and the air pump 4, thereby releasing the blocking effect of the baffle 601 on the communication channel. The channel is now open, and the air pump 4 fills the airbag 3 with gas. The airbag 3 inflates and comes into contact with the patient's lower limb.

[0022] like Figure 3 , Figure 4 and Figure 5 As shown, the extrusion assembly includes a wedge block 7, an electric slide rail 701, and an extrusion rod 702. The electric slide rail 701 is located on the top of the housing 2, and the wedge block 7 is slidably connected to the electric slide rail 701. The wedge block 7 is in extrusion engagement with the extrusion rod 702 located on one side of the connecting plate 603. The inclined surface of the wedge block 7 faces the extrusion rod 702, and the lowest point of the inclined surface is located below the extrusion rod. A reset groove 71 is provided on the side of the wedge block 7 facing the extrusion rod 702. The lowest point of the end of the wedge block 7 near the inclined surface is lower than the height of the extrusion rod 702. When the wedge block 7 moves horizontally forward, the inclined surface of the wedge block 7 and the extrusion rod 702 are pressed together, and the extrusion rod 702 moves up along the inclined surface of the wedge block 7, thereby driving the connecting plate 603 to move up along the first guide rod 6. When the wedge block 7 moves horizontally backward, the extrusion rod 702 slides along the reset groove 71, thereby preventing the extrusion rod 702 from blocking the wedge block 7 when it moves backward.

[0023] In use, the motor 5 drives the threaded rod 501 to rotate. The rotation of the threaded rod 501 causes the two first sliders 502 screwed to it to move closer or further apart, thereby adjusting the distance between the two housings 2 according to the user's lower limb condition so that the airbag 3 can contact the patient's limb. Subsequently, the slider on the electric slide rail 701 drives the wedge block 7 to move horizontally along the electric slide rail 701. When the wedge block 7 moves horizontally, the inclined surface of the wedge block 7 presses against the compression rod 702. The compression rod 702 moves upward along the inclined surface of the wedge block 7. The compression rod 702 drives the connecting plate 603 to move upward along the first guide rod 6, thereby causing the baffle 601 connected to the connecting plate 603 to move upward along the second guide rod 602. The spring 605 is stretched and deformed, thereby releasing the connection between the baffle 601 and the airbag 3 and the air pump 4. The blocking function of the channel ensures unobstructed communication between the airbag 3 and the air pump 4. When the air pump 4 operates, it injects gas into the airbag 3, causing the airbag 3 to inflate towards the patient's lower limb and compress the patient's lower limb. As the wedge block 7 moves horizontally, when the wedge block 7 compresses the next compression rod 702, the connecting plate 603 moves downward and resets under the elastic force of the spring 605 along the first guide rod 6, and the baffle 601 moves downward and resets along the second guide rod 602. In this way, through the horizontal movement of the wedge block 7, different connecting plates 603 and baffles 601 move upward sequentially from back to front, thereby connecting the air outlet of the air pump 4 with different airbags 3. This achieves the function of the airbags 3 on the box 2 inflating sequentially from back to front, achieving the effect of massaging the patient's lower limb and preventing venous thrombosis.

[0024] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
