Description

Technical Field

[0001] This invention specifically relates to a device for preventing jugular vein thrombosis. Background Technology

[0002] Blood vessels are like water pipes; if there's something blocking the pipes, the water won't flow further down or won't flow back smoothly. The same applies to human blood vessels; a blood clot is like a foreign object that obstructs blood flow. Blood clots affect normal blood circulation. Small clots in small areas or vessels may not cause obvious symptoms, but severe embolisms or clots in critical locations can be life-threatening.

[0003] Venous thromboembolism is a serious and life-threatening disease, especially since the jugular vein is a vital site that directly drains blood from the brain, face, and neck to the heart. If a thrombus occurs, it can cause local swelling, redness and swelling of the skin, or facial swelling, and may even be life-threatening. Therefore, patients need to take timely preventive measures against jugular vein thrombosis to reduce the risk of the disease.

[0004] However, existing venous thrombosis prevention devices can only prevent thrombosis in the patient's limbs. The distribution of veins in the neck is quite different from that in the limbs, and existing thrombosis prevention devices are not convenient for preventing thrombosis in the veins of the neck. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention proposes a jugular vein thrombosis prevention device to solve the technical problem mentioned in the background art that traditional thrombosis prevention devices are inconvenient for preventing thrombosis in the veins of the neck.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a jugular vein thrombosis prevention device, comprising:

The two sets of synchronous pulleys are connected by a synchronous belt, and each set of synchronous pulleys is equipped with a rocker arm.

[0017] Two sets of connecting columns are provided and spaced apart on the mounting plate. One end of each set of rocker arms is rotatably connected to the two sets of connecting columns.

[0018] In a preferred embodiment, a flexible sleeve is fitted onto the housing, and the two ends of the flexible sleeve are in contact with the two sets of mounting shells.

[0019] In a preferred embodiment, a plurality of support plates are provided on one side of the flexible belt.

[0020] In a preferred embodiment, the control panel is provided with guide protrusions distributed along its axis, and the mounting housing is provided with a guide rail, wherein the guide protrusions are slidably engaged in the guide rail along their axis.

[0021] In a preferred embodiment, the adjusting mechanism includes:

[0022] A drive gear is rotatably disposed within the mounting housing along its axis;

[0023] A drive rod is slidably mounted on the drive gear along its axis. One end of the drive rod passes through the mounting housing and extends outward. An adjusting wheel is provided at the end of the drive rod that passes through the mounting housing.

[0024] A rack is disposed on the control plate and parallel to the axis of the control plate, and the drive gear meshes with the rack;

[0025] A locking assembly, disposed within the mounting housing and connected to one end of the drive rod, is provided to fix or release the position of the rotated drive rod; and

[0026] A reset assembly is disposed on the mounting housing and connected to the drive gear to drive the rotated drive gear to reset.

[0027] In a preferred embodiment, the locking component includes:

[0028] A first ratchet disc is disposed at one end of the drive rod;

[0029] A second mounting bracket is disposed inside the mounting housing. A second ratchet disc is fixedly mounted on the second mounting bracket. The drive rod passes through the second ratchet disc so that the first ratchet disc meshes with the second ratchet disc.

[0030] An elastic element is disposed between the first ratchet disc and the inner wall of the mounting housing; and

[0031] An opening section is provided on the mounting housing and connected to the drive rod to control the drive rod to slide along its axis and drive the first ratchet disc to disengage from the second ratchet disc.

[0032] In a preferred embodiment, the reset assembly includes a constant force spring sleeved on the drive rod, one end of the constant force spring being fixedly connected to the mounting shell and the other end being fixedly connected to the drive gear.

[0033] In a preferred embodiment, the opening part includes an opening rod, one end of which passes through the mounting shell and extends outward, and the other end is provided with a connecting ring.

[0034] In a preferred embodiment, a protective sleeve is provided at the opening of the mounting shell, and both the flexible strip and the flexible plate are disposed inside the protective sleeve.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] 1. When using this jugular vein thrombosis prevention device, it is placed on the back of the neck. An adjustment mechanism drives the control plate to slide along its axis, causing it to extend beyond the mounting shell. This causes the flexible bands to bend, and the two sets of flexible bands, after bending, fix the device to the patient's neck. The bending amplitude of the flexible bands is adjustable to accommodate different users. After placement, two sets of drive components control the two mounting plates to reciprocate circumferentially at both ends of the shell, driving the two sets of mounting shells and flexible bands to reciprocate. The first and second massage columns massage the patient's jugular veins, effectively preventing neck thrombosis.

[0037] 2. During adjustment, this jugular vein thrombosis prevention device rotates by turning the adjusting wheel, which in turn drives the drive gear. The drive gear, in turn, engages with the rack, moving the control plate and causing the flexible belt to bend. During rotation, the first ratchet disc remains engaged with the second ratchet disc under the action of the elastic element, causing the constant force spring to deform. The second ratchet disc locks the position of the first ratchet disc in one direction, preventing the drive rod from reversing. To remove the device after use, simply press the end of the opening lever extending from the mounting housing, causing the drive rod to slide along its axis. This disengages the first ratchet disc from the second ratchet disc, releasing the lock on the drive rod. The constant force spring then causes the drive gear to move, resetting the control plate and the flexible belt, making the device easy to remove. This makes the device easier to use and disassemble.

[0055] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0056] Example:

[0057] like Figure 1 , 2 As shown in Figure 3, the present invention provides a jugular vein thrombosis prevention device, including a housing 101, with openings at both ends of the housing 101, and mounting plates 202 disposed in the openings at both ends of the housing 101. The housing 101 and the mounting plates 202 are connected by a drive assembly to drive the mounting plates 202 to reciprocate in a circumferential direction. The drive assembly includes a drive motor 103 disposed in the housing 101 and a first mounting frame 104, and also includes two sets of synchronous pulleys 105. One set of synchronous pulleys 105 is connected to the output shaft of the drive motor 103, and the other set of synchronous pulleys 105 is rotatably disposed on the first mounting frame 104 along its axis. The two sets of synchronous pulleys 105 are connected by a synchronous belt 107. A rocker arm 106 is disposed on each set of synchronous pulleys 105. Two sets of connecting posts 203 are disposed at intervals on the mounting plate 202, and one end of each set of rocker arms 106 is rotatably connected to the two sets of connecting posts 203 respectively.

[0058] During use, the jugular vein thrombosis prevention device can drive one set of synchronous pulleys 105 to rotate via the drive motor 103, which in turn drives the other set of synchronous pulleys 105 to move synchronously under the action of the synchronous belt 107, so that the two sets of rocker arms 106 rotate synchronously. The two sets of rocker arms 106, the mounting plate 202 and the housing 101 form a parallelogram structure. During the rotation, the two sets of rocker arms 106 can drive the mounting plate 202 to perform circumferential reciprocating motion through the four-bar linkage principle.

[0059] like Figure 2 , 5 As shown, in this embodiment, each of the two sets of mounting plates 202 is provided with a mounting shell 201 at one end. The mounting shell 201 is provided with multiple sets of first massage columns 207. The mounting shell 201 is also provided with a hinged flexible belt 401. Multiple sets of second massage columns 403 are provided on one side of the flexible belt 401.

[0060] During its circumferential reciprocating motion, the mounting plate 202 drives the mounting shell 201 to move, thereby massaging the veins in the back of the neck through multiple sets of first massage columns 207 on the mounting shell 201, and massaging the veins in the side of the neck through the second massage columns 403 on the flexible band 401, effectively preventing jugular vein thrombosis. A flexible sleeve 102 is fitted onto the shell 101, with both ends of the flexible sleeve 102 contacting the two sets of mounting shells 201. The flexible sleeve 102 seals the gap between the mounting shell 201 and the shell 101, preventing pinching injury to the patient's skin. Simultaneously, the patient can tilt their head back after wearing the device, allowing the flexible sleeve 102 to contact a wall or chair, further fixing the position of the shell 101 and improving the massage effect.

[0061] like Figure 1 , 4 As shown in Figure 5, in this embodiment, one end of the flexible plate 304 is connected to the flexible belt 401, and the other end is provided with a control plate 301. The control plate 301 is provided with guide protrusions 302 distributed along its axis. A guide rail 204 is provided inside the mounting shell 201. The guide protrusions 302 are slidably engaged in the guide rail 204 along their axis. Multiple sets of support plates 402 are provided on one side of the flexible belt 401. The control plate 301 can slide along the axis of the guide rail 204. During the sliding process of the control plate 301 inside the mounting shell 201, it can drive the flexible plate 304 and the flexible belt 401 to bend and deform, and the support plates 402 provide longitudinal support for the flexible belt 401, so that the flexible belt 401 can fix the device to the patient's neck after bending. Furthermore, a protective sleeve 801 is provided at the opening of the mounting shell 201. The flexible belt 401 and the flexible plate 304 are both placed inside the protective sleeve 801. The protective sleeve 801 shields the edges of the flexible belt 401 and the flexible plate 304, thereby improving the comfort of using the device.

[0062] like Figure 4 , 5 As shown in Figure 6, in this embodiment, an adjustment mechanism connected to the control plate 301 is provided inside the mounting housing 201 to drive the control plate 301 to slide along its axis. The adjustment mechanism includes a drive gear 601 rotatably disposed inside the mounting housing 201 along its axis and a drive rod 501 slidably disposed on the drive gear 601 along its axis. One end of the drive rod 501 passes through the mounting housing 201 and extends outward, and an adjustment wheel 502 is provided at the end of the drive rod 501 that passes through the mounting housing 201. A rack 303 parallel to the axis of the control plate 301 is provided on the control plate 301, and the drive gear 601 meshes with the rack 303.

[0063] The drive rod 501 can be rotated by rotating the adjusting wheel 502. During the rotation of the drive rod 501, the drive gear 601 is rotated, which in turn drives the control plate 301 to slide along its axis through the meshing of the drive gear 601 and the rack 303. This controls the bending deformation of the flexible plate 304 and the flexible belt 401, and the bending load is adjustable, making it convenient to fix the device to the neck of different patients. The drive rod 501 can also slide along its axis within the drive gear 601.

[0064] like Figure 3 , 6 As shown in Figures 7 and 8, in this embodiment, a locking assembly connected to one end of the drive rod 501 is provided inside the mounting housing 201. The locking assembly is used to fix or release the position of the rotated drive rod 501. The locking assembly includes a first ratchet disc 504 disposed at one end of the drive rod 501, a second mounting bracket 205 disposed inside the mounting housing 201, a second ratchet disc 206 fixedly disposed on the second mounting bracket 205, the drive rod 501 passing through the second ratchet disc 206 so that the first ratchet disc 504 meshes with the second ratchet disc 206, an elastic element 505 is disposed between the first ratchet disc 504 and the inner wall of the mounting housing 201, and the mounting housing 201 is also provided with an opening part connected to the drive rod 501. Through the opening part, the drive rod 501 can be controlled to slide along its axis to drive the first ratchet disc 504 to disengage from the second ratchet disc 206. The opening part includes an opening rod 702, one end of the opening rod 702 passing through the mounting housing 201 and extending outward, and the other end is provided with a connecting ring 701. The drive rod 501 is provided with a slot 503, and the drive rod 501 is rotatably disposed in the connecting ring 701 along its axis through the slot 503.

[0065] During the rotation of the drive rod 501, the first ratchet disc 504 is driven to rotate. The inclined surfaces of the ratchet teeth of the first ratchet disc 504 and the second ratchet disc 206 drive the drive rod 501 to slide along its axis. Under the action of the elastic element 505, the first ratchet disc 504 is always locked on the second ratchet disc 206, thereby unidirectionally locking the position of the drive rod 501 and preventing the control plate 301 from shifting after adjustment, thus ensuring the stability of the device when it is fixed to the patient's neck. After use, pressing the end of the opening rod 702 that extends outside the mounting shell 201 can drive the connecting ring 701 to move along the axis of the opening rod 702. During the movement, the connecting ring 701 drives the drive rod 501 to slide along its axis, causing the first ratchet disc 504 to disengage from the second ratchet disc 206, thereby releasing the position lock of the drive rod 501.

[0066] like Figure 6 , 7 As shown, in this embodiment, the mounting housing 201 is provided with a reset assembly connected to the drive gear 601 to drive the rotated drive gear 601 to reset. The reset assembly includes a constant force spring 602 sleeved on the drive rod 501. One end of the constant force spring 602 is fixedly connected to the mounting housing 201, and the other end is fixedly connected to the drive gear 601. During the rotation of the drive rod 501 and the rotation of the drive gear 601, the constant force spring 602 deforms. When the opening lever 702 is pressed to release the position lock of the drive rod 501, the reset capability of the constant force spring 602 can control the reset of the drive gear 601, thereby resetting the control plate 301. During the reset of the control plate 301, the flexible plate 304 and the flexible belt 401 can be reset and opened, making it convenient to remove the device.

[0067] Specific usage and beneficial effects of the present invention:

[0068] When in use, this jugular vein thrombosis prevention device is placed on the back of the neck. Rotating the adjusting wheel 502 drives the drive rod 501 to rotate. During rotation, the drive rod 501 drives the drive gear 601, which, in turn, moves the control plate 301 through its interaction with the rack 303. This causes the flexible band 401 to bend. The two sets of flexible bands 401, after bending, secure the device to the patient's neck. The bending angle of the flexible bands 401 is adjustable to accommodate different users. After placement, the drive motor 103 can be activated to rotate the two sets of rocker arms 106. During rotation, the rocker arms 106, in conjunction with the connecting column 203, control the mounting plate 202 to reciprocate circumferentially at both ends of the housing 101. This reciprocates the two sets of mounting housings 201 and the flexible bands 401, massaging the patient's jugular veins through the first massage column 207 and the second massage column 403, effectively preventing jugular thrombosis.

[0069] During rotation, the drive rod 501 in this jugular vein thrombosis prevention device maintains engagement between the first ratchet disc 504 and the second ratchet disc 206 under the action of the elastic element 505. This causes the constant force spring 602 to deform, and the second ratchet disc 206 locks the position of the first ratchet disc 504 in one direction, preventing the drive rod 501 from reversing. When the device needs to be removed after use, simply press the end of the opening lever 702 extending outside the mounting housing 201 to slide the drive rod 501 along its axis. This disengages the first ratchet disc 504 from the second ratchet disc 206, releasing the position lock on the drive rod 501. Under the action of the constant force spring 602, the drive gear 601 moves to a new position, thereby resetting the control plate 301 and the flexible belt 401. This facilitates the removal of the device, making its use and disassembly more convenient.

[0070] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
