Description

Technical Field

[0001] This utility model relates to the technical field of swallowing training, and in particular to a swallowing training device for stroke patients. Background Technology

[0002] Stroke, a common cerebrovascular disease, often leads to various complications, among which dysphagia has a high incidence rate. Currently, ice stimulation of the pharynx is a widely used and effective rehabilitation method for stroke-related dysphagia. By using low-temperature stimulation of key areas of the pharynx, such as the oral mucosa, tongue base, posterior pharyngeal wall, and soft palate, it can effectively induce the patient's swallowing reflex, strengthen the function of the swallowing muscles, and thus promote the recovery of swallowing function.

[0003] However, in actual training, traditional ice stimulation tools have significant limitations. Simple tools such as ice pops or ice spoons, used for repeated stimulation of the pharynx, gradually increase in temperature due to heat exchange with the body tissue. As the temperature of the stimulation stick rises, the effect of low-temperature stimulation weakens, making it difficult to provide a stable and effective low-temperature stimulation continuously. This hinders the smooth implementation of swallowing training and the achievement of rehabilitation goals. Utility Model Content

[0004] In view of the above-mentioned technical problems, this utility model provides a swallowing training device for stroke patients, which can continuously provide stable and effective low-temperature stimulation, effectively improving the therapeutic effect of swallowing training.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the embodiments of the present utility model.

[0030] Please see Figure 1 , Figure 1 This is a front view schematic diagram of a swallowing training device for stroke patients provided in an embodiment of the present invention. The swallowing training device includes an ice stimulation rod 1 and a base terminal 31.

[0031] The ice stimulation stick 1 has a rod-like structure, facilitating ice stimulation of the patient's pharynx by medical personnel. The first end 2 of the ice stimulation stick 1 has a cold storage chamber 3, which is filled with a cold storage agent 4. The cold storage agent 4 can be saline or pure water. The cold storage agent 4 possesses good cold storage performance, capable of maintaining a low temperature for a certain period. In the initial state, the cold storage agent 4 in the cold storage chamber 3 keeps the first end 2 of the ice stimulation stick 1 at a suitable low temperature, providing conditions for ice stimulation training of the pharynx. The first end 2 can be made into a spoon shape or other shapes suitable for ice stimulation training; no specific limitations are imposed here.

[0032] The base terminal 31 cools the ice stimulation rod 1 and monitors its usage time. The base terminal 31 has a cooling hole 5, the shape of which matches the ice stimulation rod 1, allowing for a detachable connection. When the ice stimulation rod 1 is inserted into the cooling hole 5, the cooling component 6 inside the base terminal 31 begins to function. The cooling component 6 lowers the ambient temperature inside the cooling hole 5 through compression refrigeration or thermoelectric refrigeration, thereby cooling the cold storage chamber 3 of the ice stimulation rod 1 and maintaining the refrigerant 4 at a low temperature. Furthermore, a sealing element 23 is provided at the opening of the cooling hole 5 to improve the cooling efficiency of the refrigerant 4.

[0033] The base terminal 31 is also equipped with a timing component 7. The sensing element 20 of the timing component 7 is positioned in conjunction with the cooling hole 5, and the timing component 7 can accurately record the time when the ice stimulation stick 1 is removed from the cooling hole 5. In actual swallowing training operations, once the ice stimulation stick 1 leaves the cooling hole 5 and comes into contact with the patient's pharynx, it will inevitably exchange heat with human tissue, causing its own temperature to gradually rise. The timing component 7 is set with a preset value, which can be determined based on clinical practice and the upper limit of the single use time set for ice stimulation requirements. When the cumulative time of a single use of the ice stimulation stick 1 after it is removed from the cooling hole 5 reaches the preset value, it indicates that the temperature of the first end 2 may not be suitable for continuing the ice stimulation operation, and the timing component 7 will issue an alarm in a timely manner. The alarm method can be an audible prompt or an audio-visual prompt, which can remind medical staff.

[0034] Upon receiving the alarm, medical staff can recognize that the temperature of the ice stimulation stick 1 may have risen to a level that affects the effectiveness of swallowing therapy. They can then promptly replace the ice stimulation stick 1 or reinsert it into the cooling port 5 of the base terminal 31 for cooling. Effective monitoring of the duration of each use of the ice stimulation stick 1 via the timing component 7 can significantly reduce the adverse effects of heat exchange between the ice stimulation stick 1 and human tissue during training. This ensures that the ice stimulation stick 1 can continuously provide stable and effective low-temperature stimulation during swallowing training. This stable and effective low-temperature stimulation can precisely act on key areas of the patient's pharynx, such as the base of the tongue and the posterior pharyngeal wall, fully activating the sensory nerves in the pharynx to induce the swallowing reflex, strengthening the function of the swallowing muscle groups, and thus effectively improving the therapeutic effect of swallowing training.

[0035] When using the ice stimulation stick 1 to stimulate the pharynx, the pharynx is located deep inside the oral cavity, a relatively hidden and dimly lit area. Healthcare professionals may find it difficult to clearly observe the specific location of the stimulation in the pharynx due to insufficient light when using the ice stimulation stick 1 for precise stimulation. Therefore, please refer to [link to relevant documentation]. Figure 2 In one specific embodiment, the ice stimulation stick 1 is equipped with a light lamp 8, a lighting switch 9, and a first power supply 10. The first power supply 10 can be configured as a lithium battery. The light lamp 8, as a light-emitting component, has its power supply terminal connected to the output terminal of the lighting switch 9. The lighting switch 9 controls the on / off state of the circuit, thereby realizing the operation of turning the light lamp 8 on and off. The input terminal of the lighting switch 9 is connected to the power supply terminal of the first power supply 10, which provides power support for the entire lighting system, ensuring that the light lamp 8 can work normally. When swallowing training is required, medical staff only need to turn on the lighting switch 9, and the light lamp 8 will light up, providing sufficient light illumination for the operation area of ​​the ice stimulation stick 1 in the patient's oral and pharyngeal region, thereby improving the convenience and overall efficiency of the training operation.

[0036] Furthermore, the second end 11 of the ice stimulation stick 1 is provided with a charging port 12, which is connected to the charging plate 13 on the ice stimulation stick 1. The charging plate 13 is connected to the first power source 10. Through an externally compatible charging device, such as a mobile phone charger, a dedicated charger, or a charging cable that can be connected to the power supply of medical devices, electrical energy is transmitted to the charging port 12 and charged through the charging plate 13. This allows for convenient replenishment of power to the ice stimulation stick 1 when its battery is low, enabling it to continue to work normally.

[0037] Of course, the ice stimulation rod 1 can also be recharged based on the base terminal 31. Please refer to [link / reference]. Figure 3 A charging port 14 is also provided on the base terminal 31, and a power supply terminal 15 is provided at the bottom of the charging port 14 to charge the first power supply 10. The base terminal 31 is connected to AC mains power, making full use of the space and power resources of the base terminal 31, and realizing the integration and coordination of equipment functions.

[0038] The structure of the first end 2 of the ice stimulation stick 1 can be designed according to actual needs, such as a flat structure. A flat structure can better conform to the physiological curve of the pharynx. When contacting the posterior pharyngeal wall, its larger contact area allows the low temperature to be applied evenly to the area, improving the stimulation effect. At the same time, the outer surface of the first end 2 is covered with a silicone layer 16, which can form a buffer between the ice stimulation stick 1 and the pharyngeal tissue, effectively preventing damage to the tissue caused by collision or friction, and reducing patient discomfort caused by excessively low temperature stimulation. In addition, the outer surface of the first end 2 is provided with a dot-matrix structure of protrusions 17. The protrusions 17 are distributed in a specific dot-matrix pattern and can be designed according to the nerve distribution and stimulation needs of different parts of the pharynx. For example, denser and slightly higher protrusions can be set at the base of the tongue to enhance the stimulation of the rich nerve endings in that area, thereby more accurately inducing the swallowing reflex.

[0039] The structure of the base terminal 31 will be further described below according to the embodiments of this utility model. In practical applications, since the ice stimulation stick 1 frequently enters and exits the cooling hole 5 of the base terminal 31 when performing swallowing training tasks, and may be contaminated with oral secretions, food residues and other impurities during contact with the patient's pharynx, dirt easily accumulates in the cooling hole 5.

[0040] Based on this, please continue reading Figure 3 In one specific embodiment, the base terminal 31 includes a base 18 and a rotating plate 19. The cooling component 6 and the timing component 7 are both disposed within the base 18. The rotating plate 19 is hinged to the base 18 via a hinge 27. The rotating plate 19 has a first groove 32, and the base 18 has a second groove 33. When the first groove 32 and the second groove 33 are combined, they form a cooling hole 5. The hinge structure allows the rotating plate 19 to rotate flexibly relative to the base 18. Figure 3The dashed line shows the structure when the rotating plate 19 and the base 18 are closed. A snap-fit ​​can be installed at the connection between the rotating plate 19 and the base 18. When it is necessary to clean the cooling hole 5, the rotating plate 19 can be rotated around the hinge axis to a suitable position, so that the first groove 32 and the second groove 33 that originally formed the cooling hole 5 are fully exposed. In this way, cleaning tools can easily reach into every corner of the cooling hole 5, and can perform a detailed cleaning operation on the side walls, bottom and corners of the grooves, effectively removing the dirt, impurities and bacteria that may be present.

[0041] For example, the timing component 7 includes a sensing element 20, a timer 21, and a buzzer 22.

[0042] The sensing component 20 is positioned close to the cooling hole 5. The sensing component 20 outputs a sensing signal when the ice stimulation rod 1 is removed from the cooling hole 5. The timer 21 is connected to both the preset second power supply 28 and the sensing component 20. The timer 21 starts timing upon receiving the sensing signal and outputs a response signal when a preset value is reached. The buzzer 22 is connected to the timer 21 and sounds an alarm upon receiving the response signal. The sensing component 20 can be a photoelectric sensor, reed switch, proximity switch, etc. The timer 21 can be a microcontroller or timing circuit, capable of starting timing upon receiving the sensing signal. Upon receiving the response signal from the timer 21, the buzzer 22 immediately emits an alarm sound, promptly reminding medical staff that the ice stimulation rod 1 has reached its usage limit and requires appropriate action, such as replacing the ice stimulation rod 1 or recooling it.

[0043] It can be understood that the cooling component 6 can be a chamber for storing ice. To improve ease of use, multiple components can work together for cooling. These components include a thermoelectric cooler 24, a temperature sensor 30, a heat sink 25, a fan 26, and a temperature control board 29. The thermoelectric cooler 24, as the core cooling element, utilizes its thermoelectric effect to transfer heat and thus produce a cooling effect. The temperature sensor 30 is installed at the bottom of the cooling hole 5, which can accurately sense the temperature changes inside the cooling hole 5 in real time and transmit the temperature signal to the temperature control board 29. The heat sink 25 is set close to the thermoelectric cooler and has a large heat dissipation area, which can efficiently absorb the heat generated by the thermoelectric cooler 24 during operation. The fan 26 is installed on the heat sink 25 and accelerates the dissipation of heat from the surface of the heat sink 25 to the surrounding environment through forced convection. A heat dissipation channel connecting the heat sink 25 and the fan 26 is provided on the base terminal 31, providing a dedicated path for heat dissipation and ensuring smooth heat dissipation. As the control unit of the entire refrigeration control system, the temperature control board 29 receives temperature data from the temperature sensor 30 and precisely adjusts the operating current and power of the semiconductor refrigeration component 24 according to the preset temperature range and control algorithm, thereby realizing dynamic control of the refrigeration temperature.
