Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a cold stimulation therapy device for the base of the tongue. Background Technology

[0002] Cold stimulation of the tongue root is a common physical therapy for treating swallowing disorders (such as sequelae of stroke, neuromuscular diseases, etc.). It activates the sensory nerves in the pharynx by lowering the temperature, thereby enhancing the swallowing reflex. In traditional procedures, medical staff or the patient themselves need to hold a disposable ice stick and insert it directly into the deep part of the mouth to apply point stimulation to areas such as the tongue root and soft palate.

[0003] When patients operate in front of a mirror, they usually use one hand to hold the popsicle and insert it into their mouth to the designated position because their hands can easily obstruct their view. It is easier to place the popsicle on the opposite side of the mouth with one hand, while placing it on the same side requires wrist twisting, which can easily obstruct the view and make it difficult to check whether the popsicle is in place through the mirror, which is quite inconvenient. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a tongue root cold stimulation therapy device, which can solve or at least alleviate one or more of the above-mentioned problems or other problems existing in the prior art.

[0005] This invention provides a tongue root cold stimulation therapy device, comprising:

[0006] A handle, one end of which has a first hole along its axial direction;

[0007] A connector, one end of which is inserted into the first hole and rotatably connected to the inner wall of the first hole;

[0008] A clamping head, one end of which is configured to clamp an ice pop, and the other end of which is rotatably connected to the end of the connector away from the handle; and

[0009] A linkage mechanism is provided between the handle, the connecting body, and the clamping head;

[0010] The linkage mechanism has a locked state and an unlocked state; in the locked state, the linkage mechanism restricts the relative rotation between the clamping head, the connecting body, and the handle; in the unlocked state, the linkage mechanism allows the clamping head to rotate relative to the connecting body and the connecting body to rotate relative to the handle.

[0011] Preferably, the connecting body has a mounting cavity extending along its axial direction, and the end of the connecting body away from the handle has two coaxial second holes, which communicate with the mounting cavity;

[0012] The linkage mechanism includes:

[0013] A connecting rod, the two ends of which pass through the two second holes and are connected to the clamping head, and a mounting groove extending circumferentially is provided in the middle of the connecting rod;

[0014] A fixed pulley is disposed within the mounting cavity at one end near the handle, and the axis of the fixed pulley is parallel to the axis of the connecting rod.

[0015] A linkage rope, which is sleeved around the connecting rod and the fixed pulley;

[0016] A positioning pin, one end of which is connected to the mounting groove, and the other end of which is connected to the linkage rope; and

[0017] A linkage component is disposed on the connecting body. The linkage component is configured to restrict or allow the movement of the linkage rope and to restrict or allow the connecting body to rotate within the first hole.

[0018] Preferably, the connector has a first mounting window extending along its length on each of its two opposite sides;

[0019] The linkage component includes:

[0020] Two sliders are slidably disposed in the corresponding first mounting window. A third hole is opened at the end of each slider away from the handle. The two ends of the fixed pulley are rotatably connected to the corresponding slider.

[0021] Two springs, each spring being disposed within a corresponding third hole, with one end abutting against the bottom of the third hole and the other end abutting against the inner wall of the first mounting window; and

[0022] A drive assembly is disposed on the connecting body. The drive assembly is configured to drive the linkage rope to move and to drive the linkage ropes on both sides of the fixed pulley to move closer to each other so as to drive the fixed pulley to move along the axial direction of the connecting body.

[0023] When the slider moves to abut against the inner wall of the first mounting window near the handle, the fixed pulley is stationary relative to the connecting body and the connecting body is stationary relative to the handle.

[0024] Preferably, the slider has a fourth hole that extends radially through the connector; the first hole extends outward from one end near the connector to form a support step;

[0025] The linkage component also includes:

[0026] Multiple locking blocks, wherein the multiple locking blocks are connected to the support step and are evenly distributed circumferentially along the connecting body, and a locking groove is formed between two adjacent locking blocks; and

[0027] Two locking rods are coaxially connected to both ends of the fixed pulley, and the end of the locking rod away from the fixed pulley passes through the corresponding fourth hole and extends into the locking groove.

[0028] The locking rod is clearance-fitted with the inner wall of the fourth hole, and the locking rod is configured to move out of or into the locking groove when the fixed pulley moves axially.

[0029] Preferably, the locking rod has an isosceles triangle cross-sectional shape;

[0030] The cross-sectional shape of the locking block is an isosceles triangle;

[0031] The locking groove is formed by two adjacent locking blocks, and the cross-sectional shape of the locking groove is an inverted isosceles triangle.

[0032] Preferably, the connector has two opposite sidewalls with second mounting windows extending along its axial direction; the line connecting the two second mounting windows is perpendicular to the line connecting the two first mounting windows.

[0033] The driving component includes:

[0034] Two arc-shaped cover plates are slidably disposed on the outer wall of the connector along the axial direction of the connector, and each arc-shaped cover plate has a fifth hole that penetrates radially through the connector; and

[0035] Two drive blocks, one end of each drive block is located outside the arc-shaped cover plate, and the other end slides through the corresponding fifth hole and connects to the linkage rope on the same side.

[0036] Preferably, the clamping head is made of a flexible material;

[0037] The clamping head has a clamping cavity that extends axially and is open at one end, away from the connector.

[0038] The inward contraction of the open end of the clamping cavity is designed to clamp an ice pop.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] In this invention, the dual-degree-of-freedom linkage structure of the connector and the clamping head is adopted, and one-click unlocking is achieved through the linkage mechanism. This allows the user to hold the handle with one hand and drive the clamping head to swing flexibly to the same side or opposite side of the mouth without twisting the wrist. This solves the problem that in traditional one-handed operation, the view is blocked by the hand due to the forced twisting of the wrist, and it is impossible to observe whether the popsicle is accurately in place through the mirror.

[0041] Because the device is rigid and stable when locked, it is easy to accurately deliver it to the target area; when unlocked, the tilt angle of the gripper head can be independently controlled, so that the popsicle can fit closely to curved areas such as the base of the tongue and soft palate, thereby improving the accuracy of stimulation and the therapeutic effect while ensuring endoscopic visibility.

[0066] Example 1:

[0067] This embodiment provides a tongue root cold stimulation therapy device, including a handle 10, a connector 20, a clamping head 30, and a linkage mechanism 40. The handle 10 is an ergonomic plastic grip for medical personnel or patients to hold with one hand. One end of the connector 20 is inserted into a first hole 11 at the front end of the handle 10 and is rotatably connected to the inner wall of the first hole 11 via a bearing, allowing the connector 20 to rotate relative to the handle 10 around its axis. One end of the clamping head 30 is configured to hold a disposable popsicle, and the other end is rotatably connected to the end of the connector 20 away from the handle 10, allowing it to swing relative to the connector 20.

[0068] The linkage mechanism 40 has two states: locked and unlocked.

[0069] In use, the disposable popsicle is fixed to the clamping head 30, and the device is inserted into the mouth by holding the handle 10. In the locked state, the linkage mechanism 40 restricts all relative rotation among the three components, ensuring overall rigidity and stability of the device for precise positioning. When it is necessary to adjust the angle of the popsicle to contact target areas such as the tongue root or soft palate on the same or opposite side of the mouth, the linkage mechanism 40 is unlocked. At this time, the connecting body 20 can be driven to rotate relative to the handle 10, while the clamping head 30 is driven to swing relative to the connecting body 20. This allows for flexible adjustment of the popsicle's posture without twisting the wrist or obstructing the view through the mirror, enabling multi-position stimulation.

[0070] Example 2:

[0071] This embodiment details the specific structure of the linkage mechanism 40. An axial mounting cavity 21 is provided inside the connecting body 20, and two coaxial, radially penetrating second holes 22 are provided at the end away from the handle 10, both of which communicate with the mounting cavity 21.

[0072] The linkage mechanism 40 includes a connecting rod 41, a fixed pulley 42, a linkage rope 43, a positioning pin 44, and a linkage assembly 50. The connecting rod 41 is located at the far end of the mounting cavity 21, with both ends passing through two second holes 22 and fixedly connected to the connecting end of the clamping head 30; a mounting groove 411 is circumferentially formed in its middle. The fixed pulley 42 is mounted on the end of the mounting cavity 21 near the handle 10 via a rotating shaft, with its axis parallel to the connecting rod 41. The linkage rope 43 is a high-strength fiber thread, sleeved around the connecting rod 41 and the fixed pulley 42 to form a closed loop. One end of the positioning pin 44 is embedded in the mounting groove 411, and the other end is fixedly connected to the linkage rope 43. The linkage assembly 50 is disposed on the connecting body 20 and is used to control the movement of the linkage rope 43 and the rotation of the connecting body 20 within the first hole 11.

[0073] When the linkage component 50 is locked, both the linkage rope 43 and the connecting body 20 are fixed, and the entire device is in a rigidly locked state. When the linkage component 50 is unlocked and operated, the linkage rope 43 is pulled to slide on the fixed pulley 42, which drives the connecting rod 41 to rotate through the positioning pin 44, thereby driving the clamping head 30 to swing. At the same time, the linkage component 50 also allows the connecting body 20 to rotate around the axis of the handle 10, realizing dual-degree-of-freedom adjustment and improving operational flexibility.

[0074] Example 3:

[0075] This embodiment further refines the structure of the linkage component 50. First mounting windows 23 are provided along the length direction on the two opposite sidewalls of the connecting body 20. The linkage component 50 includes two sliders 51, two springs 52, and a drive component 53. The two sliders 51 are slidably disposed within their respective first mounting windows 23, with a third hole 511 at the end facing away from the handle 10. The two ends of the fixed pulley 42 are rotatably connected to the sliders 51 on both sides. The two springs 52 are respectively placed within the third holes 511, with one end abutting the bottom of the hole and the other end abutting the inner wall of the first mounting window 23 away from the handle 10. The drive component 53 is disposed on the connecting body 20 and is used to drive the linkage rope 43 to move, and can drive the linkage ropes 43 on both sides of the fixed pulley 42 to move closer to each other, thereby pulling the fixed pulley 42 and sliders 51 away from the handle 10 along the axial direction of the connecting body 20.

[0076] When the slider 51 moves to the inner wall of the first mounting window 23 near the handle 10 under the action of the spring 52, the fixed pulley 42 is axially limited and cannot rotate. At the same time, the connecting body 20 is also locked in the first hole 11, and the entire device is locked. When the drive component 53 is activated, it overcomes the force of the spring 52 and pushes the slider 51 away from the handle 10. The fixed pulley 42 gains rotational freedom, and the connecting body 20 also gains rotational freedom around the axis of the handle 10. The device enters the unlocked state and can be adjusted at multiple angles.

[0077] Example 4:

[0078] To achieve reliable locking between the connector 20 and the handle 10, the linkage assembly 50 in this embodiment further includes locking blocks 54 and locking rods 56. A fourth hole 512 is formed on the slider 51, extending radially through the connector 20. The first hole 11 of the handle 10 extends outward from the port of the connector 20 to form an annular support step. Multiple locking blocks 54 are evenly distributed circumferentially and fixed on the support step, forming locking grooves 55 between adjacent locking blocks 54. Two locking rods 56 are coaxially fixed to both ends of the fixed pulley 42, with their distal ends passing through the corresponding fourth holes 512 and extending into the locking grooves 55. The locking rods 56 and the inner wall of the fourth holes 512 are in clearance fit.

[0079] When the slider 51 is in the near-locked position, the locking lever 56 is fully engaged in the locking groove 55, preventing the connector 20 from rotating relative to the handle 10. When the slider 51 is pushed away from the handle 10 by the drive assembly 53, the locking lever 56 moves out of the locking groove 55, releasing the constraint on the connector 20 and allowing it to rotate freely. This mechanical interlock structure ensures a stable and reliable locked state.

[0080] Example 5:

[0081] This embodiment optimizes the locking interface. The cross-section of the locking rod 56 is an isosceles triangle, and the cross-section of the locking block 54 is also an isosceles triangle. The locking groove 55 formed by adjacent locking blocks 54 is an inverted isosceles triangle. This design allows the inclined surface of the locking rod 56 to slide smoothly into the inclined surface of the locking block 54 when it resets to the locking groove 55, achieving self-guiding centering and avoiding jamming. The locking of the locking rod 56 enables the connecting body 20 to remain stationary relative to the handle 10, and also locks the rotation of the locking rod 56, thus locking the fixed pulley 42.

[0082] In addition, the non-rigid locking also has a safety yielding function: if the popsicle is accidentally subjected to excessive resistance in the mouth, the locking rod 56 can rotate slightly in the locking groove 55, causing the clamping head 30 to yield, thereby reducing the risk of damage to the oral mucosa.

[0083] Example 6:

[0084] This embodiment specifies the structure of the drive component 53. Two second mounting windows 24 are provided on opposite sides of the outer wall of the connector 20, and the line connecting them is perpendicular to the line connecting the first mounting windows 23.

[0085] The drive assembly 53 includes two arc-shaped cover plates 531 and two drive blocks 532.

[0086] The inner wall of the arc-shaped cover plate 531 is provided with a dovetail block, which slides in conjunction with a corresponding dovetail groove on the outer wall of the connector 20, allowing it to slide axially along the connector 20. A fifth radially penetrating hole is provided on the arc-shaped cover plate 531. One end of the drive block 532 is located on the outside of the arc-shaped cover plate 531 for finger pressing, and the other end passes through the fifth hole and connects to the linkage rope 43 on the same side. A flexible cover covers the outer end of the drive block 532, providing a comfortable touch and dust protection.

[0087] During operation, pressing the drive block 532 on one side with the thumb and forefinger pushes the linkage rope 43 inward, unlocking the stationary pulley and connecting body 20. Then, pushing the drive block 532 along the axis of the connecting body 20 allows for the swing adjustment of the gripping head 30. Simultaneously, twisting the arc-shaped cover plates 531 on both sides rotates the connecting body 20 as a whole, allowing for circumferential adjustment of the popsicle's orientation. The dual-degree-of-freedom operation is integrated into a single gripping motion, making operation quite convenient.

[0088] Example 7:

[0089] This embodiment optimizes the clamping head 30. The clamping head 30 is integrally injection molded from medical-grade flexible silicone, and its end away from the connector 20 has an axially open clamping cavity 31. The open end of the clamping cavity 31 contracts inward to form an elastic opening. Utilizing the elasticity and friction of the material itself, it can firmly clamp disposable ice pops of different diameters, and maintain the clamping force even after the ice pops melt and shrink. The flexible material can also absorb impact in the event of accidental collision, further improving the safety and comfort of use.

[0090] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of the invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

[0091] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
