Description

Technical Field

[0001] This invention relates to the field of rehabilitation devices for patients with swallowing disorders, and more particularly to a cold stimulation device for the rehabilitation of swallowing disorders in critically ill ICU patients. Background Technology

[0002] During the treatment of critically ill patients in the ICU, tubes are inserted into the throat for a long time. During the intubation treatment, critically ill patients in the ICU are unable to swallow. Over time, after the critically ill patients in the ICU improve and the tubes are removed, they will develop dysphagia. In order to treat dysphagia in critically ill patients in the ICU, stimulation devices are used for treatment.

[0003] Patent publication number CN214632584U discloses a cold stimulation device for the rehabilitation of dysphagia in ICU critically ill patients, including a handle and a cold stimulation treatment end. The cold stimulation treatment end is fixedly disposed at one end of the handle. A cold stimulation liquid is introduced into the handle and the cold stimulation treatment end. A disposable protective sleeve is movably sleeved on the outside of the cold stimulation treatment end. A tightening ring is threadedly connected to the outer wall of the end of the handle near the cold stimulation treatment end. The tightening ring rotates along the length of the handle, and one end of the tightening ring abuts against the outer wall of the bottom end of the cold stimulation treatment end, clamping and fixing the disposable protective sleeve sleeved on the outside of the cold stimulation treatment end.

[0004] When using the aforementioned patent, the cold stimulation liquid is injected into the cold stimulation treatment tip through the cold stimulation liquid inlet tube. Then, holding the handle, the cold stimulation treatment tip is inserted into the patient's mouth and brought close to the patient's throat. Cold stimulation is applied to the throat to stimulate the patient to swallow. However, since the patient's throat has a certain temperature, the cold stimulation treatment tip will also absorb heat from the throat when it is in contact with the throat, causing the temperature of the cold stimulation treatment tip to rise. As a result, the stimulation becomes less effective and the treatment effect is poor. Now, a cold stimulation device for the rehabilitation of swallowing disorders in ICU critically ill patients is being developed to enhance the effect of cold stimulation therapy. Summary of the Invention

[0005] This invention provides a cold stimulation device for the rehabilitation of dysphagia in ICU patients that can enhance the therapeutic effect of cold stimulation, thereby overcoming the shortcomings of existing cold stimulation devices, which have relatively poor therapeutic effects.

[0006] The technical solution is as follows: A cold stimulation device for the rehabilitation of swallowing disorders in ICU critically ill patients includes a horizontal plate and an inclined plate. The horizontal plate is connected to the top of the inclined plate. The horizontal plate is connected to symmetrically arranged arc frames. A nozzle is connected between the arc frames. Three rows of nozzles are opened at the rear of the nozzle. A cylinder is connected to the side of the nozzle away from the arc frame. A movable circular plate is slidably connected to the cylinder. A connecting frame is slidably connected to the side of the cylinder away from the nozzle. A limit rod is connected to the side of the cylinder near the connecting frame. The limit rod and the connecting frame are slidably connected. A threaded rod is rotatably connected to the side of the cylinder near the movable circular plate. The threaded rod passes through the cylinder and is threadedly connected to the connecting frame and the movable circular plate. A first return spring is connected between the connecting frame and the limit rod.

[0007] Optionally, it also includes an arc-shaped shell connected to the nozzle. The arc-shaped shell is rotatably connected to a propeller. The arc frame and the nozzle are both connected to a fixing ring on the side near the arc-shaped shell. A transmission rod is rotatably connected between the fixing rings. A baffle post is rotatably connected to the side of the nozzle away from the propeller. The baffle post extends out of the nozzle. The baffle post and the arc frame are rotatably connected. A first pulley assembly is connected between the propeller and the transmission rod. A second pulley assembly is connected between the transmission rod and the baffle post.

[0008] Optionally, it also includes a fixing mechanism for fixing the cold stimulation device for swallowing disorder rehabilitation of critically ill patients in the ICU to the patient's neck. The fixing mechanism is set on the horizontal plate and includes symmetrically arranged telescopic straps connected to the ends of the horizontal plate. A thick plate is connected between the sides of the symmetrically arranged telescopic straps away from the horizontal plate. A backrest pad is slidably connected to the thick plate. A second return spring is symmetrically arranged between the backrest pad and the thick plate.

[0009] Optionally, it also includes a holding mechanism for keeping the patient's mouth open. The holding mechanism is disposed between the arc frames and includes a pair of mouth supports rotatably connected between the arc frames. The mouth supports are provided with symmetrically arranged connecting plates. A rotating plate is rotatably connected to the side of the connecting plate away from the mouth supports. The adjacent rotating plates are rotatably connected to each other. A pull rod is rotatably connected between the adjacent rotating plates. The rotating plate is provided with a locking assembly for locking the rotating plate.

[0010] Optionally, the locking assembly includes symmetrically arranged protrusions, which are slidably connected to the rotating plate. An elastic element connects the protrusions and the rotating plate. The connecting plate has multiple grooves on the side near the protrusions, and the grooves engage with the protrusions.

[0011] Optionally, it also includes a cooling mechanism for cooling the cold stimulating liquid. The cooling mechanism is located on the side of the cylinder away from the limiting rod. The cooling mechanism includes an annular box located on the side of the cylinder away from the limiting rod. The nozzle extends out of the annular box. A fan is connected to the side of the annular box away from the cylinder. Multiple heat-absorbing elements are connected inside the annular box, and the nozzle passes through the spaces between the heat-absorbing elements.

[0012] Optionally, it also includes a collection mechanism for collecting excess liquid in the oral cavity. The collection mechanism is disposed between the cylinder and the arc frame. The collection mechanism includes a round head box connected to the cylinder. The round head box is slidably connected to a movable round head plate. A one-way suction pipe is connected to the side of the round head box away from the limiting rod. The one-way suction pipe is connected to the arc frame. A driving component is provided inside the round head box for driving the movable round head plate to move.

[0013] Optionally, the driving assembly includes two screws rotatably connected to the round head box, the movable round head plate and the screws are threadedly connected, a third pulley assembly is connected between the screws near the limiting rod, a fourth pulley assembly is connected between one of the screws and the threaded rod away from the limiting rod, and a one-way water outlet pipe is provided on the side of the round head box near the one-way water suction pipe.

[0014] Optionally, the backrest cushion has an arc shape and is made of rubber.

[0015] Optionally, a crossbar is provided on the side of the pull rod away from the mouth support.

[0016] The beneficial effects of this invention are: 1. By moving the handheld connecting frame forward, the connecting frame will drive the threaded rod to rotate, and the threaded rod will drive the moving circular plate to move backward, so that the cold stimulation liquid is directly sprayed onto the patient's throat through the nozzle. Firstly, the cold stimulation liquid directly contacts the throat, so that the patient's throat can receive cold stimulation continuously. Secondly, the impact force generated by the spray can make the stimulation of the patient's throat better, thus enhancing the effect of cold stimulation therapy.

[0017] 2. This invention uses an irritating liquid to drive the propeller, which in turn causes the baffle column to intermittently block each row of nozzles, preventing continuous spraying and making the throat more comfortable for patients with weak tolerance, thus achieving a better therapeutic effect.

[0018] 3. In this invention, people pull the lever, which causes the rotating plate to rotate and the connecting plate to rotate, thereby opening the patient's mouth with the mouth support, which facilitates cold stimulation treatment for the patient.

[0019] 4. The present invention can absorb heat from the cold stimulating liquid through the heat-absorbing component, and the hot air is discharged backward by the fan, thereby achieving the cooling of the cold stimulating liquid.

[0020] 5. The present invention enables the third and fourth pulley assemblies to rotate the screw by rotating the threaded rod, thereby moving the movable round head plate forward to draw out the liquid in the patient's mouth, preventing the patient from choking on the liquid, and also making it easier to perform cold stimulation therapy on the patient.

Detailed Implementation

[0037] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0038] Example 1: Cold stimulation device for the rehabilitation of dysphagia in ICU patients, such as... Figures 1-4As shown, it includes a horizontal plate 1 and an inclined plate 2. The horizontal plate 1 is welded to the top of the inclined plate 2. Arc frames 3 are connected to the left and right sides of the bottom of the horizontal plate 1. A nozzle 5 is connected between the arc frames 3. Three rows of nozzles are opened at the rear of the nozzle 5. The three rows of nozzles are staggered. The front end of the nozzle 5 is connected to a cylinder 4. A movable circular plate 401 is slidably connected inside the cylinder 4. When the movable circular plate 401 moves backward, it can spray cold stimulating liquid through the nozzle 5 to the patient's throat. A connecting frame 6 is slidably connected to the lower front part of the cylinder 4. A limiting rod 8 is connected to the lower front part of the cylinder 4. The limiting rod 8 and the connecting frame 6 are slidably connected. A threaded rod 7 is rotatably connected to the middle of the cylinder 4. The front part of the threaded rod 7 extends out of the front part of the cylinder 4. The front part of the threaded rod 7 is threadedly connected to the connecting frame 6. The threaded rod 7 is threadedly connected to the movable circular plate 401. A first return spring 9 is connected between the lower front part of the connecting frame 6 and the front part of the limiting rod 8.

[0039] When using this cold stimulation device for dysphagia rehabilitation in ICU patients, first inject the cold stimulation liquid into the cylinder 4. Then, the patient opens their mouth, and the rear part of the nozzle 5 is inserted into the patient's mouth, with the nozzle facing the patient's throat. Then, the person holds the lower front part of the cylinder 4 and the connecting frame 6, pulling the connecting frame 6 forward. The first return spring 9 is compressed, and the forward movement of the connecting frame 6 drives the threaded rod 7 to rotate. The rotation of the threaded rod 7 drives the moving disc 401 to move backward. The backward movement of the moving disc 401 sprays the cold stimulation liquid directly into the patient's throat through the nozzle. The cold stimulation liquid is continuously... The liquid is sprayed directly into the throat, ensuring continuous cold stimulation without the temperature of the oral cavity causing the sprayed liquid to rise. This maintains the temperature of the sprayed liquid. Additionally, the impact of the cold stimulation liquid into the throat further stimulates the patient's throat, enhancing the therapeutic effect. After the connecting frame 6 moves forward to its foremost position, it is released. Under the action of the first reset spring 9, the connecting frame 6 moves backward to reset. The backward movement of the connecting frame 6 causes the threaded rod 7 to reverse, which in turn causes the moving circular plate 401 to move forward to reset.

[0040] Example 2: Based on Example 1, Figures 5-7As shown, it also includes an arc-shaped shell 10, which is connected to the front left part of the nozzle 5. A propeller 11 is rotatably connected to the middle of the arc-shaped shell 10. When the cold stimulating liquid passes through the propeller 11, it will drive the propeller 11 to rotate. The front part of the arc-shaped frame 3 on the left and the front part of the nozzle 5 are both connected to the fixing rings 12. A transmission rod 13 is rotatably connected between the fixing rings 12. A baffle post 15 is rotatably connected to the rear part of the nozzle 5. The arc-shaped frame 3 is used to block the nozzle. The left part of the baffle post 15 extends out of the nozzle 5. The left part of the baffle post 15 and the left part of the arc-shaped frame 3 are rotatably connected. A first pulley assembly 14 is connected between the left side of the propeller 11 and the left side of the transmission rod 13. A second pulley assembly 16 is connected between the left side of the transmission rod 13 and the left side of the baffle post 15.

[0041] Because the nozzle 5 has three rows of nozzles, and each row sprays in a different direction, as mentioned earlier, the cold stimulating liquid is continuously sprayed into the patient's throat through the three rows of nozzles in the nozzle 5. The spray range of the three rows of nozzles is also relatively wide. When the liquid is continuously sprayed to stimulate the patient's throat, some patients have low tolerance and may experience adverse effects, leading to vomiting. To avoid this problem, baffle posts 15 and other components are installed. During the process of the cold stimulating liquid being sprayed from the nozzles through the nozzle 5, the liquid passes through the propeller 11. The water flow drives the propeller 11 to rotate slowly. The propeller 11 is connected to the first pulley assembly 14, the transmission rod 13, and the second... The pulley assembly 16 drives the baffle column 15 to rotate slowly. When the baffle column 15 rotates to block the first row of nozzles, the first row of nozzles stops spraying, while the other two rows of nozzles continue spraying. When the baffle column 15 rotates to block the second row of nozzles, the second row of nozzles stops spraying, while the other two rows of nozzles continue spraying. When the baffle column 15 rotates to block the third row of nozzles, the third row of nozzles stops spraying, while the other two rows of nozzles continue spraying. In this way, by rotating the baffle column 15, each row of nozzles can be blocked intermittently, and the spray direction of each row of nozzles is inconsistent. This allows each row of nozzles to spray intermittently, making the throat more comfortable for patients with weak tolerance and achieving a better treatment effect.

[0042] like Figure 8As shown, it also includes a fixation mechanism for fixing the cold stimulation device for dysphagia rehabilitation of critically ill patients in this ICU to the patient's neck. The fixation mechanism is set on the horizontal plate 1 and includes symmetrically arranged telescopic straps 17. The two telescopic straps 17 are respectively connected to the left and right sides of the horizontal plate 1. A thick plate 18 is connected between the rear parts of the two telescopic straps 17. A back pillow pad 19 for padding the back of the patient's neck is slidably connected to the thick plate 18. The front part of the back pillow pad 19 is arc-shaped and made of rubber, so that the patient's back of the neck and the back pillow pad 19 will feel more comfortable when they fit together. A second return spring 20 is connected between the left and right sides of the back of the back pillow pad 19 and the back of the thick plate 18.

[0043] When using the cold stimulation device for swallowing rehabilitation of critically ill ICU patients described above, it is necessary to hold the cylinder 4 continuously, which is very troublesome and laborious. Therefore, a fixing mechanism is set up so that the telescopic strap 17 is placed around the patient's neck, and the back pillow 19 is placed on the back of the patient's neck. Under the action of the second return spring 20, the back pillow 19 will remain close to the back of the patient's neck. In this way, the inclined plate 2 can be pressed against the front of the patient's neck by the telescopic strap 17, thus fixing the cold stimulation device for swallowing rehabilitation of critically ill ICU patients in the position of the patient's neck, which is convenient to use.

[0044] like Figures 8-11 As shown, it also includes a holding mechanism for keeping the patient's mouth open. The holding mechanism is set between the arc frame 3 and includes two mouth supports 21. The two mouth supports 21 are rotatably connected between the rear parts of the arc frame 3. Connecting plates 22 are welded to the left and right sides of the mouth supports 21. Rotating plates 23 are rotatably connected to the front of the connecting plates 22. Two adjacent rotating plates 23 are rotatably connected to each other. A pull rod 24 is rotatably connected between the two adjacent rotating plates 23. A crossbar is provided at the front of the pull rod 24, which makes it easier for people to pull the pull rod 24 by holding the crossbar. The front of the rotating plates 23 is provided with a locking component for locking the rotating plates 23. The locking component includes a protrusion 25, which is slidably connected to the left and right sides of the front of the rotating plates 23. An elastic element 26 is connected between the protrusion 25 and the rotating plates 23. A groove 2501 is opened on the left and right sides of the front of the connecting plate 22. The groove 2501 and the protrusion 25 are engaged.

[0045] In the preceding text, during the cold stimulation procedure, the patient's mouth needs to remain open. However, if the mouth remains open for an extended period, it may close on its own, which would interfere with the treatment. Therefore, a retaining mechanism is implemented to keep the patient's mouth open. First, the nozzle 5 is inserted into the patient's mouth, and the mouth support 21 also enters the patient's oral cavity. Then, the person holds the lever 24 and pulls it forward. The lever 24 causes the two upper rotating plates 23 to swing upward and the two lower rotating plates 23 to swing downward. The rotating plates 23 then cause the upper connecting plate 22 to rotate upward and the lower connecting plate 22 to rotate downward. This causes the connecting plate 22 to rotate and unfold the mouth support 21 outward, opening the patient's mouth. During the rotation between the rotating plates 23 and the connecting plate 22, the groove 2501 and the protrusion... The protrusions 25 and 2501 will intermittently overlap. When the protrusions 25 and 2501 are misaligned, the protrusions 25 move outward, and the elastic element 26 is compressed. When the protrusions 25 and 2501 overlap, under the action of the elastic element 26, the protrusions 25 move inward and re-enter the groove 2501. This allows the rotating plate 23 and the connecting plate 22 to be locked together. After the mouth support 21 opens the patient's mouth to a suitable size, the pull rod 24 is stopped. With the cooperation between the groove 2501 and the protrusions 25, the angle between the rotating plate 23 and the connecting plate 22 is limited, thus keeping the mouth support 21 in a state that supports the patient's oral cavity. This makes it easier to perform cold stimulation treatment on the patient. After the treatment is completed, the pull rod 24 is moved backward by hand, and the mouth support 21 is rotated and reset by the connecting plate 22 and the rotating plate 23, no longer supporting the patient's oral cavity.

[0046] like Figures 12-13 As shown, it also includes a cooling mechanism for cooling the cold stimulating liquid. The cooling mechanism is located at the rear of the cylinder 4. The cooling mechanism includes an annular box 27, which is located at the rear of the cylinder 4. The front of the nozzle 5 passes through the upper part of the annular box 27. The rear of the annular box 27 is connected to a fan 28 by bolts. Multiple heat-absorbing elements 29 are evenly connected inside the annular box 27. The nozzle 5 passes through the upper part of the heat-absorbing elements 29.

[0047] In order to keep the temperature of the cold stimulating liquid lower and improve its stimulating effect when it passes through the nozzle 5, a cooling mechanism is set up. The fan 28 can be turned on. When the cold stimulating liquid passes through the nozzle 5, the heat-absorbing component 29 can absorb the heat in the cold stimulating liquid, and the hot air is discharged backward by the fan 28. This can further cool the cold stimulating liquid, so that the temperature of the cold stimulating liquid is lowered for subsequent cold stimulation treatment. When not in use, the fan 28 can be turned off.

[0048] like Figures 14-15As shown, it also includes a collection mechanism for collecting excess liquid in the mouth. The collection mechanism is located between the cylinder 4 and the right-side arc frame 3. The collection mechanism includes a round head box 31, which is fixedly connected to the upper right part of the cylinder 4. A movable round head plate 35 is slidably connected inside the round head box 31. A one-way suction pipe 34 is connected to the rear of the round head box 31. The one-way suction pipe 34 is connected to the right-side arc frame 3. The suction port at the rear of the one-way suction pipe 34 is located below the mouth support 21. The one-way suction pipe 34 can only draw liquid back into the round head box 31 in one direction. The round head box 31 is equipped with a mechanism for moving the movable round head plate 35 forward. The drive assembly includes two screws 32, which are rotatably connected to the round head box 31. The movable round head plate 35 is threadedly connected to the screws 32. A third pulley assembly 33 is connected between the front parts of the screws 32. A fourth pulley assembly 36 is connected between the lower screws 32 and the rear of the threaded rod 7. The rotation of the threaded rod 7 drives the screws 32 to rotate through the fourth pulley assembly 36, causing the movable round head plate 35 to move forward and draw the liquid in the oral cavity back into the round head box 31 for collection. A one-way water outlet pipe 30 is provided at the lower rear of the round head box 31. The one-way water outlet pipe 30 can only discharge the liquid in the round head box 31 in one direction.

[0049] Because the cold-stimulating liquid is continuously sprayed into the patient's mouth, a large amount of liquid will accumulate inside. Excessive liquid can cause choking and affect swallowing. Therefore, a collection mechanism is installed to draw the liquid back and collect it. First, the one-way outlet pipe 30 is connected to the external receiving pipe. Then, after the patient's mouth is opened, the suction port of the one-way suction pipe 34 is positioned inside the patient's mouth. When the threaded rod 7 rotates, it drives the screw 32 to rotate through the fourth pulley assembly 36 and the third pulley assembly 33. The rotation of the screw 32... The movable round head plate 35 will move forward, and the movable round head plate 35 will draw the liquid in the oral cavity back into the round head box 31 through the suction port of the one-way suction pipe 34 for collection. This can prevent the liquid from affecting the patient's treatment. When the threaded rod 7 reverses, it will drive the screw 32 to reverse through the fourth pulley assembly 36 and the third pulley assembly 33. The screw 32 will drive the movable round head plate 35 to move backward and reset. The movable round head plate 35 will discharge the liquid into the external receiving manifold through the one-way water outlet pipe 30, so that the liquid can be discharged automatically.
