Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an ice stimulation training device for the rehabilitation of swallowing disorders. Background Technology

[0002] Dysphagia is one of the most common and serious complications in stroke patients. Studies show that 22% to 65% of stroke patients experience dysphagia, making them prone to malnutrition and weakened immunity. Aspiration and choking can lead to aspiration pneumonia and even suffocation and death. Long-term nasogastric tube placement can cause anxiety, depression, and other negative emotions, severely impacting patients' quality of life. Currently, there is no specific drug treatment for dysphagia in stroke patients; rehabilitation therapy is the primary approach.

[0003] Ice stimulation, as a rehabilitation therapy, can effectively improve the sensitivity of the soft palate and pharynx, increase sensory input in stroke patients with dysphagia, regulate neuronal excitability, and rebuild the neural functional network, thereby restoring swallowing function. At the same time, it is highly praised by scholars at home and abroad because of its advantages of safety, effectiveness and ease of operation.

[0004] Currently, medical cotton swabs are commonly used in clinical practice as the primary tool for ice stimulation. The specific method involves soaking the cotton swab in saline solution and then freezing it. Local stimulation is then applied, centered on the uvula, covering the anterior and posterior palatal arches, soft palate, pharynx, posterior tongue wall, and K-spot. Extensive and prolonged contact with the stimulation area is recommended. Due to the significant therapeutic effects of ice stimulation, patient compliance and acceptance are high. Most patients frequently use popsicles, ice bars, or homemade ice cubes for ice stimulation both in the hospital and at home after discharge.

[0005] Chinese Patent Publication No. CN220833546U discloses a rehabilitation training device for dysphagia after stroke, belonging to the field of rehabilitation equipment technology. It includes an ice stimulation pen and a storage box. The ice stimulation pen includes a body with an operating head fixedly mounted on its upper part. The storage box includes a box body with a top cover hinged to its upper end. A UVC lamp bead is located at the lower end of the top cover. A charging base is located inside the box body. The body includes a casing and a semiconductor cooling component. A button is located at the front end of the casing. The casing is made of silicone. A back cover is fixedly mounted on the lower end of the casing. Heat dissipation holes are provided on the outer wall of the back cover, and a charging magnetic sheet is located at the lower end of the back cover. Therefore, this invention allows for convenient disinfection, is simple to operate, and can perform not only intraoral ice stimulation but also neck massage, thus mitigating the risk of choking to some extent and demonstrating practicality.

[0006] However, conventional methods like those described above have the following shortcomings: 1) Medical cotton swabs are thin and short, and cannot be subjected to force. Improper handling can easily cause them to break, which can lead to the swab tip falling into the mouth and causing choking. Also, because of their short length, they cannot stimulate the posterior pharyngeal wall. They can achieve the effect of point stimulation (K point), but for surface stimulation, the cotton swab needs to be repeatedly rubbed, which will cause the cold effect of the cotton swab to decrease rapidly, affecting the treatment effect. Patients cannot easily operate them at home, and the risk is relatively high.

[0007] 2) Popsicles, ice pops, or homemade ice cubes: While popsicles and ice pops are readily available and provide a long-lasting cooling effect, they are highly susceptible to ambient temperature changes during preparation and easily melt into water. Patients with swallowing difficulties may experience choking or even aspiration because they cannot swallow the liquid properly. Prolonged use of popsicles or ice pops can also cause discomfort due to the coldness of the melted liquid, which can damage the spleen and stomach. Homemade ice cubes are problematic because their small size makes them difficult for patients to handle, fails to stimulate the effective portion of the ice, and can cause choking if they melt and fall into the throat. Furthermore, holding a whole ice cube in the mouth is often too much for patients to tolerate and can easily lead to frostbite. In summary, homemade ice cubes are cold, melt easily, and have low safety.

[0008] 3) Existing rehabilitation training devices for dysphagia after stroke can generally only achieve single ice stimulation rehabilitation training, lacking comprehensive treatments such as taste stimulation and vibration stimulation. This makes the entire treatment process longer, more complicated, and less cooperative, reducing patient compliance and acceptance of the treatment, which is not conducive to the patient's rapid recovery. Summary of the Invention

[0009] The purpose of this invention is to provide an ice stimulation training device for the rehabilitation of dysphagia. This invention overcomes the limitations of existing ice stimulation training devices for the rehabilitation of dysphagia after stroke, which generally only provide single ice stimulation therapy and lack auxiliary taste and vibration stimulation for comprehensive treatment. This results in a longer, more complex, and less cooperative treatment process, which in turn reduces patient compliance and acceptance of the treatment, hindering the patient's recovery.

[0010] To achieve the above objectives, the technical solution adopted by the present invention to solve its technical problem is as follows: An ice stimulation training device for dysphagia rehabilitation was designed. It utilizes an auxiliary opening mechanism to help open the patient's mouth, and a control mechanism allows the ice stimulation training head to stimulate different parts of the patient's throat.

Each of the two rotating wheels is equipped with a pull rope, one end of which is connected to the rear side of the connecting frame, and the other end is connected to the auxiliary opening mechanism. The control rod is connected to a taste stimulation module on the left side of the middle via an elastic infusion tube, and to a refrigeration module on the right side of the middle via an elastic cooling strip, both located between the upper and lower partitions.

[0013] Preferably, an infusion channel is provided through the control mounting rod and the mounting sleeve, the tail of the infusion channel is connected to the elastic infusion tube, and the head is connected to the spherical head of the ice stimulation training head; The head of the mounting sleeve is equipped with a telescopic sleeve, and a spring is installed inside the telescopic sleeve for retracting the ice stimulation training head.

[0015] Preferably, the auxiliary opening mechanism includes: The support frame is extended, and there are two of them. Parts of them are connected to the front side of the inside of the box through a rotating shaft, and are connected to the pneumatic assembly through the pneumatic rod assembly through the partition. At least two miniature cameras are provided, each disposed in one of the two heads of the expansion bracket, and the ice stimulation training head passes through the two heads of the expansion bracket.

[0016] Preferably, the pneumatic assembly includes: A pneumatic cylinder is installed on the top of the upper partition plate, and a piston rod is connected to its tail. A switch is connected to the tail of the piston rod through an L-shaped connecting plate. A pneumatic hose is connected to the head of the pneumatic cylinder and is connected to the pneumatic rod assemblies on the upper and lower sides respectively.

[0017] Preferably, the pneumatic rod assembly includes: The pneumatic fixing rod is connected to the box body through a fixing plate, and its outer end is connected to the pneumatic tube. The pneumatic telescopic rod has its outer end slidably connected to the inner end of the pneumatic fixed rod, and is provided with a telescopic first limit block and a second limit block spaced apart and symmetrically arranged in the middle, with a limit ring sleeved on the free end. An elastic rubber ring is disposed through the partition plate and abuts against the limiting ring.

[0018] Preferably, the cooling module includes: A refrigeration unit is installed on the top right side of the lower partition and connected to the elastic cooling strip. A refrigeration base is provided on it, and a refrigeration chamber is fastened to the top of the refrigeration base, and a spare ice stimulation training head set is placed inside it. A refrigeration unit heat sink is connected to the refrigeration unit.

[0019] Preferably, the taste stimulation module includes: The medicine box is installed on the top left side of the lower partition and connected to the elastic infusion tube. The medicine box is provided with multiple outward-facing medicine storage holes. A medicine bottle is embedded in the medicine storage hole and plugged into the plug at the bottom of the medicine storage hole. At least two movable pressure plates are provided on the inner wall of the medicine storage hole, and the movable pressure plates abut against the outside of the medicine bottle. A manual airbag, connected via an air supply tube to a chamber within the medicine box, is used to control the movable pressure plate.

[0020] The beneficial effects of this invention are: This invention employs an auxiliary opening mechanism to open the patient's mouth, and a miniature camera is installed on its head to transmit images of the inside of the patient's mouth. This allows medical personnel to control the ice stimulation training head for treatment based on the images via a control mechanism. During this process, taste stimulation and vibration stimulation can be combined to guide the patient to swallow. When swallowing, the patient's mouth closes, causing the auxiliary opening mechanism to close, and the ice stimulation training head will retract a certain distance simultaneously. This multi-functional linkage method prevents the inside of the patient's mouth from touching the stimulation rod when swallowing, thereby preventing vomiting or damage to the oral cavity wall.

[0021] In this invention, a pneumatic component can be used to drive a pneumatic rod assembly to control the opening and closing of an auxiliary opening mechanism.

The air pressure inside the cavity of the medicine box is controlled by a manual airbag, which drives the movable pressure plate to squeeze the medicine bottle in the medicine storage hole, delivering the taste-stimulating medicine through the infusion channel into the ice stimulation training head. This medicine is then applied to the areas inside the patient's mouth that require stimulation for auxiliary treatment, thereby improving the patient's cooperation.

[0023] The present invention also includes a cooling base within the cooling module, and different spare stimulation head sets are inserted into the cooling base. These can be replaced according to actual use, so as to meet the needs of different parts of the body as much as possible and ensure the patient's comfort during treatment.

Therefore, they should not be construed as limiting the scope of protection of this invention.

[0030] like Figure 1-23 As shown, this invention provides an ice stimulation training device for the rehabilitation of swallowing disorders, including an upward-facing box 1 for easy housing of various components and placement in a treatment room. Patients can sit in the treatment room and face the stimulation bar for treatment. For bedridden patients with limited mobility, the device can be fixed to a small table or shelf on the bedside table, meeting the needs of different usage scenarios. A cover 11 is provided at the top opening of the box 1 to achieve closed operation. Two spaced partitions 15 are provided inside the box 1 to facilitate the fixed installation of various components, ensuring that each component is firmly fixed in its corresponding position, thereby guaranteeing the stability and reliability of the device during operation.

[0031] It also includes an auxiliary opening mechanism 3, which is set in the training port 13 on the front side of the box body 1 to assist patients with mouth opening disorders in opening their mouths. An ice stimulation training head 5 is set inside the ice stimulation training head 5. The tail of the ice stimulation training head 5 is connected to a control mechanism 4. The control mechanism 4 can control the up and down, left and right, and forward and backward movements of the ice stimulation training head 5 to stimulate different parts of the patient's oral cavity. A pneumatic component 9 is set on the top left side of the upper partition 15 and is connected to the auxiliary opening mechanism 3 through a pneumatic rod component 8 to drive the auxiliary opening mechanism 3 to open the patient's oral cavity so as to better carry out related treatment or training work.

[0032] The control mechanism 4 includes a control lever 41 that passes vertically through the cover plate 11 and is fitted with a telescopic fixing sleeve 46 that is connected to the top of the cover plate 11. The telescopic fixing sleeve 46 is made of elastic rubber to accommodate the movement of the control lever 41 in the front-back, left-right, and up-down directions. The control mounting lever 42 is located between the upper and lower partition plates 15, and its tail is connected to the lower end of the control lever 41 by a universal ball joint to facilitate the movement of the control mounting lever 42 in different directions. The mounting sleeve 43 is connected to the training port 13 through the connecting bracket 2. One end of the sleeve is connected to the head of the control mounting lever 42, and the other end passes through the auxiliary opening mechanism 3 and is connected to the tail of the ice stimulation training head 5. The ice stimulation training head 5 is detachably connected to the mounting sleeve 43, either by plug-in or threaded connection. At the same time, a heat insulation sleeve is wrapped around the tail of the ice stimulation training head 5 and the outside of the mounting sleeve 43 to reduce temperature damage.

[0033] In the above embodiment, a movable hole 111 is provided at the point where the control lever 41 penetrates the cover plate 11, and the inner diameter of the movable hole 111 is larger than the outer diameter of the control lever 41, so that the control lever 41 can move in different directions. Then, the head can be driven to move in different directions by means of a universal ball joint with the tail of the control mounting lever 42, thereby driving the ice stimulation training head 5 to move in different directions to stimulate different parts of the patient's mouth. At the same time, the heat insulation sleeve on the ice stimulation training head 5 also has the function of preventing discomfort to the patient's lips, so as to improve the comfort during its use.

[0034] In the above scheme, the tail of the control rod 42 is connected to a vibrator 47 via a rubber rod 471. The vibrator 47 is installed at the bottom of the box 1 to drive the ice stimulation training head 5 installed at its head to achieve vibration stimulation. Two rotating wheels 44 are symmetrically arranged on the left and right sides of the middle part. Pull ropes 45 are threaded through the two rotating wheels 44 respectively. One end of the pull rope 45 is connected to the rear side of the connecting frame 2, and the other end is connected to the auxiliary opening mechanism 3. The left side of the middle part of the control rod 42 is connected to the taste stimulation module 6 via an elastic infusion tube 64, and the right side of the middle part is connected to the cooling module 7 via an elastic cooling strip 72. Both are located between the upper and lower partitions 15. The elastic design of the elastic infusion tube 64 and the elastic cooling strip 72 is to adapt to the movement of the control rod 42 in different directions and to stimulate the patient's oral cavity in combination with the taste stimulation module 6 and the cooling module 7.

[0035] An infusion channel 48 is provided through the control rod 42 and the mounting sleeve 43. The end of the infusion channel 48 is connected to the elastic infusion tube 64 to deliver the stimulating agent in the taste stimulation module 6. The head is connected to the ball head 51 of the ice stimulation training head 5. Multiple spray holes are evenly distributed on the ball head 51 to facilitate the spraying of the taste stimulating agent, so that it can act on the areas inside the patient's mouth that need stimulation. The head of the mounting sleeve 43 is provided with a telescopic sleeve 431, and a spring 432 is provided inside the telescopic sleeve 431. The ice stimulation training head 5 is retracted via a telescopic sleeve 431 slidably connected to the head of the mounting sleeve 43. This allows the ice stimulation training head 5 to retract under swallowing conditions, preventing the inside of the patient's mouth from touching the ice stimulation training head 5 when swallowing. After swallowing, the restoring elasticity of the spring 432 causes the ice stimulation training head 5 to pop out. At the same time, the spring 432 also provides a certain amount of buffering space during the stimulation process of the ice stimulation training head 5, thereby improving the comfort of its use.

[0036] In the above embodiments, in order to provide taste stimulation to assist in the stimulation treatment effect, the taste stimulation agent can be injected into the infusion channel 48 through the elastic infusion tube 64 via the taste stimulation module 6, and finally sprayed out through the spray hole on the ball head 51 of the ice stimulation training head 5 to the area to be stimulated, so as to achieve taste stimulation.

[0037] During the stimulation process, when the patient swallows, the upper and lower teeth close when the patient swallows, causing the auxiliary opening mechanism 3 to close. This pulls the connecting frame 2 inward by the pull rope 45 around the rotating wheel 44, causing the ice stimulation training head 5 to retract a certain distance simultaneously. This prevents the inside of the patient's mouth from touching the ice stimulation training head 5 when the patient swallows, thus avoiding damage to the patient's oral cavity wall.

[0038] In the above scheme, the connecting frame 2 includes two connecting plates 21, which are respectively connected to the inner walls of the left and right sides of the training port 13. The mounting block 23 is connected to the left and right connecting plates 21 by multiple elastic rubber strips 22 on both sides. The elastic rubber strips 22 can deform under pressure and automatically recover after the pressure is removed, providing mobility for the installation sleeve 43. The middle part of the installation sleeve 43 is spherically connected to the center of the mounting block 23 to ensure that it can move in different directions.

[0039] In the above scheme, the auxiliary opening mechanism 3 includes two opening brackets 31, and some of them are connected to the front side of the box body 1 through the rotating shaft 32, and are connected to the pneumatic component 9 through the pneumatic rod assembly 8 through the partition 15. At least two miniature cameras 33 are provided, and are respectively set at the heads of the two opening brackets 31. The ice stimulation training head 5 passes through the heads of the two opening brackets 31.

[0040] In the above embodiment, the two expansion brackets 31 are arranged opposite each other to form a U-shaped structure, with their outer ends abutting each other and having grooves adapted to the patient's teeth. The inner ends remain parallel. The pneumatic rod assembly 8 is arranged on the upper and lower sides of the outer end of the expansion bracket 31. The pneumatic rod assembly 8 can drive the expansion bracket 31 to rotate around the pivot 32 through the air pressure, so as to realize the opening and closing of the outer end of the expansion bracket 31. At the same time, the miniature camera 33 can clearly observe the condition inside the patient's oral cavity, which is more conducive to the ice stimulation training head 5 performing stimulation treatment.

[0041] In the above scheme, the pneumatic component 9 includes a pneumatic cylinder 92, which is installed on the top of the upper partition 15. A piston column 94 is connected to its tail. A switch 91 is connected to the tail of the piston column 94 through an L-shaped connecting plate. The switch 91 is slidably connected to the cover plate 11. The pneumatic pipe 93 has a U-shaped pipe structure. Its middle part is connected to the head of the pneumatic cylinder 92. Its two ends are respectively connected to the upper and lower pneumatic rod assemblies 8 to drive the support bracket 31 to assist the opening of the patient's mouth.

[0042] The pneumatic rod assembly 8 includes a pneumatic fixing rod 81, which is connected to the box body 1 via a fixing plate 811. One rod is connected to the bottom of the cover plate 11, and the other is connected to the bottom of the inner side of the box body 1. Its outer end is connected to the pneumatic tube 93. The pneumatic telescopic rod 82 has its outer end slidably connected to the inner end of the pneumatic fixing rod 81. A telescopic first limiting block 83 and a second limiting block 84 are symmetrically arranged at intervals in the middle. The first limiting block 83 and the second limiting block 84 have a triangular structure and are arranged inside the rod wall of the pneumatic telescopic rod 82. A spring or other elastic element is arranged between them to ensure that the first limiting block 83 and the second limiting block 84 can retract into the pneumatic telescopic rod 82 after being subjected to pressure, and pop out of the pneumatic telescopic rod 82 after the pressure is removed. A limiting ring 86 is sleeved on the free end. An elastic rubber ring 87 is arranged through the partition plate 15 and abuts against the limiting ring 86.

[0043] In the above embodiment, by pushing the switch 91, the L-shaped connecting plate drives the piston rod 94 to move forward within the pneumatic cylinder 92. This allows gas to be injected into the pneumatic fixing rod 81 through the pneumatic pipe 93, causing the pneumatic telescopic rod 82 to extend. The pneumatic telescopic rod 82 then moves inward along the elastic rubber ring 87, compressing the first limiting block 83 and the second limiting block 84 through the elastic rubber ring 87, achieving a certain degree of locking. By squeezing the inner end of the support bracket 31 against which the patient's head rests, the inner ends of the support bracket 31 are brought closer together, thus opening the patient's mouth through its outer end. When the patient's mouth is closed, the patient's teeth will squeeze and open the outer end of the bracket 31, causing its inner ends to move away from each other. This will squeeze the pneumatic telescopic rod 82, causing it to retract into the pneumatic fixing rod 81. At the same time, a locking arc surface 85 is provided on the outer end of the first limiting block 83 and the second limiting block 84 to ensure that the first limiting block 83 and the second limiting block 84 retract into their interior during the retraction of the pneumatic telescopic rod 82, thus making the locking effect ineffective, until the limiting ring 86 at the head of the pneumatic telescopic rod 82 abuts against the elastic rubber ring 87 to prevent the pneumatic telescopic rod 82 from detaching from the partition 15.

[0044] In the above scheme, the cooling module 7 includes a cooling unit 71, which is installed on the top right side of the lower partition 15 and connected to the elastic cooling strip 72 to reduce the temperature of the ice stimulation training head 5 and ensure that it maintains a stable low temperature. A cooling base 75 is provided on it. The top of the cooling base 75 has multiple holes, and spare ice stimulation training head sets are inserted into it. The ice stimulation training head sets include heads of different shapes such as spherical and flat, so as to be suitable for ice stimulation treatment of different parts of the patient. A cooling chamber 74 is fastened to the top of the cooling base 75 to avoid the low temperature condition being disturbed by the outside. The cooling unit heat sink 73 is connected to the cooling unit 71.

[0045] In the above embodiment, the cooling unit 71 employs semiconductor cooling technology, which can stably maintain a low temperature of -10~-15℃ to ensure the temperature of the stimulation rod. The heat dissipation seat 73 protrudes from the heat dissipation vent 14 on the right side wall of the housing 1 to ensure good heat dissipation. When it is necessary to replace or use the ice stimulation training head 5, the cooling chamber 74 can be opened, and ice stimulation training heads 5 with different shapes can be used as needed. The elastic cooling strip 72 transfers the low temperature of the cooling unit 71 to the ice stimulation training head 5 for treatment; its elastic design is to accommodate the movement of the control mechanism 4.

[0046] In the above scheme, the taste stimulation module 6 includes a medicine box 62, which is installed on the top left side of the lower partition 15 and connected to the elastic infusion tube 64 to accommodate the movement of the control mechanism 4. The medicine box 62 has multiple outward-facing drug storage holes 621, and a sealing cap 121 is fastened to the outside of the drug storage holes 621. The sealing cap 121 is inserted into the window 12 on the left side of the box body 1. The medicine bottle 63, made of elastic rubber, is embedded in the drug storage hole 621 and inserted into the drug storage tube. At least two movable pressure plates 65 are provided on the inner wall of the medicine storage hole 621 on the plug 622 at the bottom of the hole 621. The outer side of the movable pressure plate 65 penetrates the inner wall of the medicine storage hole 621, and the inner side of the movable pressure plate 65 abuts against the outer side of the medicine bottle 63. Under the change of air pressure in the cavity of the medicine box 62, the movable pressure plates 65 can move closer and further away from each other in the medicine storage hole 621. The manual air bag 61 is connected to the cavity in the medicine box 62 through the air supply pipe 611 and is used to control the movable pressure plates 65.

[0047] In the above embodiment, when it is necessary to perform taste stimulation on the patient, the originally closed sealing cap 121 on the device can be opened first. Then, the medicine bottle 63 containing the specific medicine can be carefully inserted into the medicine storage hole 621 specifically used for storing medicine bottles. During this process, it is necessary to ensure that the medicine bottle 63 can be accurately placed between the movable pressure plates 65 and that the bottle mouth of the medicine bottle 63 is precisely inserted into the plug 622. After completing these steps, the previously opened sealing cap 121 can be closed again to restore it to a sealed state.

[0048] Next, the manual airbag 61 can be squeezed manually. When the manual airbag 61 is squeezed, the gas inside is forced into the cavity wall inside the medicine box 62 through the gas delivery tube 611. As gas continues to enter, the air pressure inside the cavity gradually increases. Due to the increase in air pressure, the movable pressure plates 65 located in the medicine storage hole 621 will move closer together under the pressure. The process of the movable pressure plates 65 moving closer together will squeeze the medicine bottle 63 located between them. Under such squeezing, the medicine inside the medicine bottle 63 will be squeezed out, flow through the plug 622 into the elastic infusion tube 64, and finally be delivered to the ice stimulation training head 5. The ball head 51 of the ice stimulation training head 5 will spray the medicine into the patient's mouth, thereby achieving the purpose of stimulating the patient's taste.

[0049] Specific implementation examples: When using this ice stimulation training device for dysphagia rehabilitation, the following steps are included: 1. Select According to the patient's needs, open the cooling chamber 74, take out the corresponding ice stimulation training head 5, install it on the head of the installation sleeve 43, and place the head of the auxiliary opening mechanism 3 into the patient's mouth.

[0050] 2. Auxiliary opening Pushing the switch 91 causes the piston rod 94 to move forward in the pneumatic cylinder 92 via the L-shaped connecting plate. Gas is injected into the pneumatic fixing rod 81 of the pneumatic rod assembly 8 through the pneumatic pipe 93 connected to its head, causing the pneumatic telescopic rod 82 to slide out of the pneumatic fixing rod 81. Then, the first limiting block 83 or the second limiting block 84 can be passed through the elastic rubber ring 87 according to the degree of the patient's mouth opening. The head of the pneumatic telescopic rod 82 squeezes and opens the bracket 31, thus opening the patient's mouth.

[0051] 3. Ice stimulation therapy When the refrigeration unit 71 is started, the low temperature is transferred to the ice stimulation training head 5 installed on the head of the control mechanism 4 via the elastic cooling strip 72. The control lever 41 is moved back and forth, left and right, or up and down, which in turn drives the control mounting lever 42 to move back and forth, left and right, or up and down. This causes the ice stimulation training head 5 installed on the head of the mounting sleeve 43 to perform ice stimulation treatment in different parts of the patient's mouth. During the treatment, the ice stimulation training head 5 can adaptively extend and retract according to the elastic action of the spring 432 in the telescopic sleeve 431 of the mounting sleeve 43, so as to ensure the comfort of the treatment process.

[0052] When the patient swallows, the upper and lower teeth close during swallowing due to the oral cavity structure, causing the auxiliary opening mechanism 3 to close. The upper and lower rotating shafts 32 cause the inner end of the support bracket 31 to open away from the installation sleeve 43. The rotating wheel 44 rotates, and the pull rope 45 pulls the connecting frame 2 inward, causing the ice stimulation training head 5 to retract a distance simultaneously, preventing the patient's oral cavity from touching the stimulation rod when swallowing, thereby inducing vomiting or causing damage to the oral cavity wall.

[0053] During this process, the outer ends of the first limiting block 83 and the second limiting block 84 are provided with locking arc surfaces 85, which ensure that the first limiting block 83 and the second limiting block 84 retract into their interior during the retraction of the pneumatic telescopic rod 82, thereby making the locking effect ineffective, until the limiting ring 86 at the head of the pneumatic telescopic rod 82 abuts against the elastic rubber ring 87 to prevent the pneumatic telescopic rod 82 from separating from the partition plate 15.

[0054] 4. Taste stimulation Open the sealed cap 121, place the medicine bottle 63 between the movable pressure plates 65 in the medicine storage hole 621, and insert the head of the medicine bottle into the plug 622. Manually squeeze the manual air bag 61 to inject gas into the cavity inside the medicine box 62 through the gas delivery tube 611. After the air pressure inside the medicine box 62 increases, it will squeeze the movable pressure plate 65. The movable pressure plate 65 will squeeze the medicine bottle 63 in the medicine storage hole 621, so that the medicine in the medicine bottle 63 is sent into the infusion channel 48 through the elastic infusion tube 64, and then sprayed into the patient's mouth through the ball head 51 of the ice stimulation training head 5, acting on the part of the patient's mouth that needs stimulation to achieve taste stimulation.
