Description

Technical Field

[0002] Dysphagia is a clinical symptom that is caused by damage to the mandible, lips, tongue, soft palate, throat, esophageal sphincter or esophagus, which makes it impossible to safely and effectively deliver food from the mouth to the stomach. Studies have found that electrical stimulation can make the stimulated muscles show a clear positive training effect. The normal swallowing reflex requires not only sufficient muscle strength, but also good sensory feedback and coordinated muscle operation. Electrical stimulation therapy can effectively enhance muscle strength, improve the flexibility and coordination of pharyngeal muscles, thereby increasing sensory integration input, effectively promoting the recovery of swallowing function, and improving dysphagia.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figures 1 to 5 As shown, an embodiment of the utility model provides a rehabilitation training device for patients with dysphagia, including: a device body 1, a main shaft 8, fixedly installed in the middle of a side of the device body 1 away from the input end, a spring pin connector 7, installed on a side of the device body 1 close to the main shaft 8 and electrically connected thereto, a switching component, sleeved on the main shaft 8, a plurality of electrode heads 3, arranged inside the switching component, and each time the switching component is switched, only one of the plurality of electrode heads 3 is always moved out to the side of the switching component away from the device body 1.

[0027] The working principle and beneficial effects of the above technical scheme are as follows: when the device is to be used, a switching assembly with multiple electrode heads 3 installed inside is sleeved on the main shaft 8, so that the spring pin connector 7 contacts one of the electrode heads 3 and forms a passage, and then the start button on the device body 1 is pressed, and the electrode head 3 can be used to perform electrical stimulation on the patient, wherein the working principle of the device body 1 is the prior art and is not described in detail herein. When it is necessary to switch between electrode heads 3 of different types, the switching assembly is moved for switching, and another type of electrode head 3 can be cut out and contacted with the spring pin connector 7 to form a new passage, and the original electrode head 3 is retracted into the switching assembly. Similarly, each electrode head 3 can be switched and connected at a time until the electrode head 3 of the required type is selected and put into use. The present embodiment adopts the technical means of cooperating the switching assembly with multiple electrode heads 3, and can quickly switch the type of the electrode head 3 without removing the electrode head 3, thereby overcoming the shortcomings of the prior art and achieving the technical effect of improving work efficiency.

[0028] In one embodiment: the switching component includes a cylinder 4, a through hole 12 for inserting the main shaft 8 is opened through the cylinder 4, a plurality of step holes 11 are opened through the cylinder 4, and the plurality of step holes 11 are distributed in a ring shape around the through hole 12 at equal intervals, each step hole 11 is slidably connected to the corresponding electrode head 3, and a metal conductive block 9 is fixedly connected to one end of the electrode head 3 close to the spring pin connector 7, each metal conductive block 9 is connected to the step surface of the step hole 11 through an insulating spring 13, and the metal conductive block 9 is electrically connected to the corresponding electrode head 3.

[0029] The working principle and beneficial effects of the above technical solution are as follows: when it is necessary to switch different electrode heads 3, the cylinder 4 is pulled along the axis of the main shaft 8 in the direction away from the device body 1, and the electrode head 3 ejected inside is retracted under the elastic force of the corresponding insulating spring 13, and then the cylinder 4 is rotated with the main shaft 8 as the axis in units of ninety degrees. Each time it is rotated one unit, a model of electrode head 3 can be switched, until the required model of electrode head 3 is switched to the top of the corresponding spring ejector connector 7, and then the cylinder 4 is pushed along the axis of the main shaft 8 in the direction close to the device body 1, and the spring ejector connector 7 ejects the corresponding electrode head 3 and forms a passage with it, and the device can be put into use.

[0030] In one embodiment: each metal conductive block 9 is provided with a groove for the spring pin connector 7 to be embedded.

[0031] The working principle and beneficial effects of the above technical solution are as follows: the groove can better fit the head of the spring ejector connector 7, thereby improving the stability of the connection between the two.

[0032] In one embodiment, the number of electrode heads 3 is four.

[0033] The working principle and beneficial effects of the above technical solution are as follows: the electrode head 3 is set to four different models, which is convenient for applying precise stimulation to different parts of the patient's mouth, thereby improving the practicality of the device.

[0034] In a specific embodiment: the device body 1 is provided with locking components corresponding to the number of the electrode heads 3 .

[0035] The working principle and beneficial effects of the above technical solution are as follows: the locking assembly can fix the cylinder 4 on the device body 1, thereby improving the stability of the device when in use.

[0036] In one embodiment: the locking assembly includes a protrusion 6 slidably set on the device body 1, a slide groove for the protrusion 6 to be embedded in is opened on the device body 1, the protrusion 6 is connected to the bottom of the slide groove through a compression spring 10, an extrusion plate 5 is fixedly connected to the corresponding position on the cylinder 4, and a card groove for the corresponding protrusion 6 to be embedded in is opened through the extrusion plate 5.

[0037] The working principle and beneficial effects of the above technical solution are as follows: a force is applied to the cylinder 4 so that the cylinder 4 approaches the device body 1, so that the multiple extrusion plates 5 respectively squeeze the corresponding protrusions 6, and the compression spring 10 is compressed until the protrusion 6 is embedded in the corresponding slot of the extrusion plate 5 under the elastic force of the compression spring 10, thereby locking the cylinder 4 relative to the device body 1.

[0038] In one embodiment: the device body 1 is fixedly connected with a number of U-shaped plates 2 corresponding to the number of protrusions 6 .

[0040] Working principle and usage process:

[0041] When it is necessary to switch to a different electrode head 3, the cylinder 4 is pulled along the axis of the main shaft 8 in a direction away from the device body 1, and the compression spring 10 is compressed, so that the multiple extrusion plates 5 are separated from the heads of the corresponding protrusions 6, until the spring ejector connector 7 and the corresponding step hole 11 are separated, and the electrode head 3 ejected inside is retracted under the elastic force of the corresponding insulating spring 13, and then the cylinder 4 is rotated with the main shaft 8 as the axis in units of ninety degrees. Each time it is rotated one unit, a model of electrode head 3 can be switched until the required model of electrode head 3 is selected. After the head 3 is switched to the top of the corresponding spring ejector pin connector 7, the cylinder 4 is pushed along the axis of the main shaft 8 toward the device body 1. The spring ejector pin connector 7 contacts and squeezes the corresponding metal conductive block 9, ejects the corresponding electrode head 3, and forms a passage with it. At the same time, the extrusion plate 5 is inserted into the corresponding U-shaped plate 2 and squeezes the corresponding protrusion 6 until the protrusion 6 is embedded in the circular groove on the corresponding extrusion plate 5 under the elastic force of the compression spring 10. Then it can be put into use again. When it needs to be switched again, just follow the above process.
