Description

Technical Field

[0002] Dysphagia is one of the common complications after stroke. Patients experience difficulty eating and aspiration, which can lead to aspiration pneumonia, worsening of the patient's condition, prolonged course of illness, and even life-threatening consequences. Currently, there are two types of rehabilitation training for dysphagia: indirect training and direct training. Ice stimulation is a common rehabilitation training method in indirect training and is widely used in clinical practice.

[0003] Pharyngeal ice stimulation mainly stimulates the inner wall of the oropharynx through cold water or frozen ice cotton swabs, which increases the sensitivity of swallowing reflex and increases sensory input; at the same time, by stimulating the relevant muscles of the oropharynx, it increases the sensitivity of food perception and speeds up swallowing; improves the coordination of oropharyngeal nerve muscles; reduces excessive saliva secretion in the mouth; through stimulation, gives the cerebral cortex and brainstem a warning sensory stimulation; increases attention to eating and swallowing, thereby improving swallowing function.

A driving mechanism for driving the freezing turntable to rotate is provided in the insulation barrel, and the control end of the driving mechanism is connected to the control switch through a controller, and the control switch controls the controller to send a driving signal to the driving mechanism. The driving mechanism drives the freezing turntable to rotate each time at an angle A between two adjacent slots. At the same time, a rod installation groove is arranged inside the bottom of the insulation barrel below one of the slots. The rod installation groove is connected to the insulation chamber, and the rod is slid up and down and installed in the rod installation groove. The diameter of the rod is smaller than the maximum diameter of the ice cotton swab. 18 insertion holes for the insertion of the rod are arranged at the bottom of the freezing turntable. Each insertion hole is arranged at the center position of the bottom of each slot, and the insertion hole is connected to the slot one by one. The insulation cover is provided with a swab outlet hole corresponding to the position of the rod, and the center axes of the swab outlet hole and the insertion hole coincide. A telescopic mechanism is embedded in the bottom of the insulation barrel to cooperate with the rod, and an extension trigger component is arranged on the driving mechanism to cooperate with the telescopic mechanism. The extension trigger component triggers the extension of the telescopic mechanism to push the rod into the corresponding slot, so that the picking end of the cotton swab in the slot extends out of the insulation cover; a retraction trigger component is arranged on the driving mechanism or the insulation barrel to cooperate with the telescopic mechanism, and the retraction trigger component triggers the retraction of the telescopic mechanism to reset the rod for the next rotation of the freezing turntable and the ejection and removal of the ice cotton swab.

[0032] Reference Figure 1-7As shown in the figure, as a specific implementation of the storage device of the present invention, the driving mechanism includes a limit shaft, an external meshing incomplete gear mechanism, a bevel gear transmission mechanism and a reduction motor, the output shaft of the reduction motor is connected to the external meshing incomplete gear mechanism through the bevel gear transmission mechanism, and the output end of the external meshing incomplete gear mechanism is connected to the limit shaft. The bevel gear transmission mechanism is a gear transmission between intersecting axes composed of a pair of first bevel gears, which is used to change the direction of power transmission. The external meshing incomplete gear mechanism is composed of a driving wheel and a driven wheel. Only one or several teeth are made on the driving wheel. According to the requirements of the movement time and the rest time, the gear teeth that mesh with the driving wheel are made on the driven wheel; the rest part is a locking arc. When the two gear teeth enter into meshing, like the gear transmission, the toothless part is positioned by the locking arc to make the driven wheel stationary. Here, the specific parameter settings of the external meshing incomplete gear mechanism are conventional technical means in the field, and those skilled in the art can set them according to the actual situation, as long as the driving wheel drives the driven wheel to rotate each time at an angle between two adjacent slots.

[0033] In this embodiment, the reduction motor is arranged horizontally, one of the first bevel gears of the bevel gear transmission mechanism is connected to the output shaft of the reduction motor, and the other first bevel gear of the bevel gear transmission mechanism is connected to the shaft between the driving wheel to convert the rotation of the vertical plane into the rotation of the horizontal plane. The limit shaft is connected to the driven wheel shaft, and the lower end of the limit shaft is arranged in a cylindrical shape so that it can be rotatably installed on the bottom of the insulation barrel, and the upper end of the limit shaft is a rectangular parallelepiped or other limit structure and extends upward to the freezing turntable. The center position of the bottom of the freezing turntable is matched with the upper end of the limit shaft to set a limit groove, so that the freezing turntable and the limit shaft can rotate synchronously. In this embodiment, each rotation of the motor drives the driving wheel to rotate one circle, and the gear teeth on the driving wheel cooperate with the driven wheel to drive the driven wheel to rotate at an angle A.

[0034] Based on the above-mentioned driving mechanism, the telescopic mechanism specifically includes a rod sleeve, a first turntable, a first spring, a sliding column, a first sliding groove that is opened on the side of the rod sleeve and is inclined to cooperate with the sliding column, and a locking assembly that is arranged at the bottom of the insulation barrel to cooperate with the insertion rod. In this embodiment, the plug rod is arranged on a side close to the driving wheel and is cylindrical, the rod sleeve is hollow cylindrical, the rod sleeve is sleeved outside the lower part of the plug rod, and the rod sleeve is slidably connected to the plug rod, the first turntable is fixedly arranged at the bottom of the rod sleeve, the first spring is arranged in the rod sleeve below the plug rod and between the first turntable and the plug rod, and the first turntable and the rod sleeve are rotatably installed inside the bottom of the heat preservation barrel, two slide posts are arranged and are respectively arranged on both sides of the plug rod, two first slide grooves are arranged and correspond to the slide posts one by one, the first slide groove is a through groove and is inclined in the circumferential direction, and the inclination angle here is 70°, the length of the slide post is greater than the thickness of the rod sleeve, the slide post passes through the first slide groove and extends to the inner wall of the heat preservation barrel, and the heat preservation barrel cooperates with the slide post to open a vertically arranged second slide groove, and the height of the second slide groove is the height of the first slide groove. The first spring is a compressed spring, and the setting of the first spring can drive the plug rod to move upward and extend under the action of the first spring. The locking assembly includes a locking member rotatably mounted on the bottom of the heat preservation barrel, a reset member such as a torsion spring or a spring embedded in the bottom of the heat preservation barrel in cooperation with the locking member, and a locking groove is arranged on the upper part of the insertion rod in cooperation with the locking member. The locking assembly is arranged to prevent the insertion rod from moving upward and extending under the action of the first spring.

[0035] In this embodiment, the locking member is configured as a pawl, and the pawl is provided with a connecting shaft. The connecting shaft is rotatably connected to the heat preservation barrel, and the pawl rotates with the connecting shaft as a reference point. A rotation groove for the pawl to rotate is provided at the bottom of the heat preservation barrel; the reset member is configured as a torsion spring, and the torsion spring is sleeved on the connecting shaft, and the two ends are respectively embedded in the pawl and the bottom of the heat preservation barrel. The specific structure of the torsion spring and the connection setting with the locking member and the heat preservation barrel only need to ensure that the locking member can be reset to be stuck in the locking groove. This is a conventional technical means in this field and will not be described in detail here.

[0036] Furthermore, the sliding column is cylindrical and rotatably connected to the insertion rod, or the sliding column includes a fixed shaft and a sleeve fitted on the fixed shaft. The friction between the sliding column and the first and second sliding grooves is reduced as much as possible to ensure that the insertion rod can smoothly move upward and extend under the action of the first spring.

[0037] Corresponding to the telescopic mechanism, the extension trigger assembly is a toggle member connected to the driving wheel shaft in the external meshing incomplete gear mechanism, and the toggle member can be rotatably installed at the bottom of the insulation barrel. While the driving wheel rotates to drive the driven wheel to rotate a fixed angle A, the toggle member coaxially connected to the driving wheel rotates to the corresponding position of the locking member, and the locking member is toggled away from the locking groove. At this time, the insertion rod moves up to the corresponding socket and pushes the ice cotton swab upward from the slot to the outside of the insulation cover. In this embodiment, the toggle member is configured as a cam, the cam is connected to the driving wheel shaft, and the cam is fixedly arranged above the driving wheel and is at the same horizontal position as the pawl. A rotation groove for the cam to rotate is provided at the bottom of the insulation barrel. The retraction trigger assembly includes gear teeth arranged on the first rotating disk, a synchronous gear connected to the driving wheel shaft in the external meshing incomplete gear mechanism, the synchronous gear is an incomplete gear, and is provided with a plurality of continuous gear teeth. The arc of the synchronous gear driven by the incomplete gear to rotate is consistent with the arc of the positive projection of the first slide slot, the synchronous gear can mesh with the first rotating disk, and the diameter of the synchronous gear is larger than the diameter of the first rotating disk. The first rotating disk is driven to rotate by the rotation of the gear to realize the retraction of the extended insertion rod.

[0038] In this embodiment, after the ice cotton swab is loaded into the storage device, the driving motor is controlled to rotate through the control switch, driving the driving wheel to rotate one circle clockwise. During this process, the driving wheel first drives the driven wheel to rotate A°. At the same time, the cam coaxially connected to the driving wheel drives the pawl away from the locking groove, and the insertion rod is popped out by the first spring to push the ice cotton swab out of the insulation cover. The doctor takes the ice cotton swab, and the pawl moves to the side of the insertion rod under the action of the torsion spring. Afterwards, when the driving wheel is about to complete one circle of rotation, the synchronous gear coaxially connected to the driving wheel engages with the first turntable to drive the first turntable to rotate, retracting the insertion rod to its original position, and the pawl is stuck in the locking groove under the action of the reset member.

[0039] Reference Figure 8-11As shown, as another specific implementation of the present invention, the telescopic mechanism includes a third slide, a compression spring, a vertical rod and a locking assembly. The third slide is opened inside the bottom of the heat preservation barrel, below the plug rod installation groove and connected to the plug rod installation groove; one end of the vertical rod is fixedly set in the third slide, and the other end extends upward into the plug rod, and the plug rod cooperates with the vertical rod to set a vertical groove; the compression spring is set outside the vertical rod in the third slide, and the locking assembly includes a pawl rotatably installed inside the bottom of the heat preservation barrel, a torsion spring embedded between the pawl and the bottom of the heat preservation barrel, and the top side of the plug rod cooperates with the pawl to open a locking groove. By setting one end of the pawl in the locking groove, the plug rod is restricted from moving upward. Only when the end of the pawl moves away from the locking groove by the extension trigger assembly, the plug rod can be inserted into the jack upward to eject the ice cotton swab in the slot. The extension trigger assembly in this embodiment is the same as the extension trigger assembly in Example 1, both of which are toggle members connected to the active wheel shaft, and the corresponding avoidance groove is set inside the bottom of the heat preservation barrel to cooperate with the toggle member. The retraction trigger assembly includes a cross bar, a second turntable, a fixed column, and a slide rail. The second turntable can be rotatably installed inside the bottom of the heat preservation barrel. One end of the fixed column is fixedly connected to the second turntable, and one end of the fixed column can be rotatably installed in the slide rail. A rotating shaft is arranged at the center position of the second turntable away from the fixed column. The rotating shaft can be rotatably installed inside the bottom of the heat preservation barrel, and one end of the rotating shaft extends outside the heat preservation barrel. One end of the cross bar extends into the inside of the plug rod and can be slid up and down and installed on one side of the plug rod. The plug rod cooperates with the cross bar to form a sliding groove. One end of the cross bar inserted into the plug rod is provided with a through hole for the vertical rod to pass through. The cross bar is arranged at the top of the sliding groove. The end of the sliding groove is connected to the slide rail. The slide rail and the cross bar are in the same horizontal plane and the two are arranged vertically. The fixed column can slide back and forth in the slide rail. A fixed block is arranged on the circumferential side of the second turntable inside the bottom of the heat preservation barrel, and an arc groove for the fixed block to slide is arranged in the heat preservation barrel. An elastic rope is fixed between the fixed block and the fixed groove, and the rotating shaft and the disc are reset by the elastic rope.

[0040] In this embodiment, the control switch is used to control the cold turntable to rotate to a preset angle A, and the insertion rod is aligned with the corresponding slot. At the same time, the cotton swab is ejected by the insertion rod through the cam. After the ice cotton swab is taken out, the insertion rod is reset by rotating the shaft, and then the shaft is reset under the action of the elastic rope.

[0041] In this embodiment, further, a pressure switch can be provided in the heat preservation barrel at the other end position corresponding to the arc groove, such as Fig.10 As shown, when the shaft completes rotation, the fixed block is pressed against the pressure switch at the same time. The pressure switch is connected to the controller and sends a signal to the controller. The controller controls the reduction motor to make the driving wheel rotate one circle to insert the rod into the next slot.
