Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an intelligent tracheal advancement training device. Background Art

[0002] Cervical spondylosis is the leading cause of cervical spinal cord injury in adults. Anterior cervical surgery is the classic surgical treatment for cervical spondylosis. Dysphagia is one of the most common complications after anterior cervical surgery. It not only affects patients' quality of life and increases medical costs, but can also be life-threatening by inducing coughing and aspiration, leading to aspiration pneumonia and suffocation.

[0003] Tracheal advancement training is used to simulate the traction during surgery, which can effectively reduce the occurrence of dysphagia after anterior cervical surgery. The specific method of tracheal advancement training is: medical staff or the patient themselves gently push the patient's thyroid cartilage from right to left to offset it 1 cm from the midline of the neck. The operation starts 4 days before surgery, with 3 sets per day and 15 times per set. In clinical practice, patients often find it difficult to perceive whether the pushing force and time meet the prescribed "standards" during training; in addition, during repeated pushing, the pushing force and efficiency may decrease due to hand fatigue. The above situation seriously affects the effect of tracheal advancement training. To ensure the effect, existing tracheal advancement training often requires the assistance of others, or the patient himself to complete it under concentrated conditions. The monotonous and boring training content takes up a lot of patients' time, making it difficult to persist. Utility Model Content

Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0027] This embodiment provides an intelligent tracheal advancement training device, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, it includes a shell 1, an electric push rod 2 is arranged in the shell 1, the working end of the electric push rod 2 extends to the outside of the shell 1, the working end of the electric push rod 2 is connected to the push cylinder 3, the end of the push cylinder 3 is provided with a push head 4, and the surface of the push head 4 is concave arc-shaped; a controller 5 and a battery 6 are also provided in the shell 1, the battery 6 is electrically connected to the controller 5 and the electric push rod 2, the controller 5 is electrically connected to the electric push rod 2, and the controller 5 controls the working state of the electric push rod 2; a control key 7 and a display screen 8 are provided on the controller 5, and the control key 7 and the display screen 8 are exposed on the shell 1.

[0028] Preferably, the housing 1 is provided with an extension sleeve 12, the end of the extension sleeve 12 is provided with a through hole, the working end of the electric push rod 2 is inserted into the extension sleeve 12, the push cylinder 3 is sleeved on the outer periphery of the extension sleeve 12, and the push head 4 is provided with a stepped countersunk hole. A screw passes through the push head and the extension sleeve in sequence and is threadedly connected to the working end of the electric push rod 2. The electric push rod 2 drives the push cylinder 3 to move axially along the extension sleeve 12. Preferably, at least one guide limit strip 13 is provided along the axial direction of the outer periphery of the extension sleeve 12, and a guide groove is provided on the inner side wall of the push cylinder 3. The guide groove is adapted to the guide limit strip 13 to ensure that the relative positions of the push cylinder 3 and the extension sleeve 12 remain consistent.

[0029] Furthermore, the surface of the pusher head 4 is detachably connected to a contact gasket 9, and the contact gasket 9 is made of a flexible material such as a medical silicone material. Preferably, a plurality of anti-slip grooves are provided on the surface of the contact gasket 9 to improve the anti-slip performance between the contact gasket and the patient's skin. In a preferred embodiment, the contact gasket 9 is semi-enclosed and wrapped around the outer periphery of the pusher head 4. In another preferred embodiment, the contact gasket 9 is in the form of a sheet, and a buckle is provided on the back of the contact gasket 9, and a card hole is provided on the surface of the pusher head 4, and the buckle is engaged in the card hole to achieve fixation. The contact gasket 9 is connected to the pusher head 4 in a detachable connection manner, which is convenient for disassembly, disinfection and replacement, and reduces the risk of cross infection.

[0030] Preferably, the pusher head is provided with a variety of specifications, including different sizes and hardness, etc., which can meet the neck requirements of patients with different fat and thin types and improve the comfort of patients. Furthermore, the pusher tube 3 is provided with a variety of specifications of different lengths. When the extension and retraction amount of the electric push rod 2 is determined, the pusher tube 3 of different lengths can be replaced to meet the neck requirements of patients with different fat and thin types.

[0031] Furthermore, a mechanical sensor 10 is installed between the push head 4 and the contact gasket 9, and the mechanical sensor 10 is communicatively connected to the controller via a telescopic wire. When the push head 4 contacts the human neck, a certain pressure will be generated on the mechanical sensor 10. When the controller detects a pressure change, it makes a judgment and presets a pressure threshold. When the detected pressure exceeds the threshold, the electric push rod 2 drives the push cylinder 3 to retract, the display screen displays the threshold alarm, and the push cylinder 3 is reset to the initial state. According to clinical data, the threshold is gradually adjusted. According to preliminary tests, when the thrust is about 2 kgf, the thyroid cartilage can be pushed without damage (subsequent clinical adjustments and verification of the precise data are required). Therefore, the range of the mechanical sensor is selected to be 0~5 kgf to meet the requirements of tracheal pushing training.

[0032] Furthermore, the control keys include an on / off key, a displacement adjustment key, a pressure adjustment key, a time adjustment key, etc. The control keys can be used to set parameters such as the displacement, pressure threshold, and working time of the push head. After the parameters are set, the device can start working to assist the patient in completing tracheal pushing training. The recommended training frequency is: 3 groups per day (performed 30 minutes after a meal), 15 times per group, each lasting 1 minute, with an interval of 1 minute. Each push is made so that the trachea is pushed across the midline and lasts for more than 1 minute. The display screen shows data such as the pushing distance, push head pressure, and working time.

[0033] Furthermore, the controller is provided with a wireless transmission component, which is connected to the mobile terminal for communication. The wireless transmission component is Bluetooth or WIFI, and can transmit the number of daily training sessions and training time to the mobile terminal for medical staff to view.

[0034] Furthermore, the housing 1 also has a connecting structure for detachably connecting to the neck support 11, allowing the entire device to be mounted on the neck support 11. The connecting structure can be a snap fastener, with the housing and the neck support snapping together. The connecting structure can also be a stud provided on the housing, with a through hole provided in the neck support, and a screw passing through the neck support connects to the stud, locking the housing to the neck support.

[0035] When in use, first select a device with a push head 4 of appropriate specifications according to the patient's body shape, install the device on the side wall of the neck collar corresponding to the patient's surgical side, and the patient wears the neck collar with the push head 4 facing the patient's neck from the side. Figure 5As shown. The control key 7 of the controller is used to set the push displacement, pressure size, and holding time. Then, the electric push rod 2 is turned on by the control key 7. The working end of the electric push rod 2 is pushed out linearly along the extension sleeve 12. The push cylinder 3 connected to the working end of the electric push rod 2 and the push head 4 are pushed out together to produce corresponding linear displacement; the displacement distance is adjusted by the control key 7 to achieve that the push head 4 contacts the human neck and pushes the trachea to produce appropriate deformation. The type of motor in the electric push rod used in this application is a stepper motor. The motor shaft of the stepper motor drives the screw in the screw mechanism to rotate. The screw mechanism converts the rotational motion of the motor into the linear motion of the nut. The working push rod of the electric push rod is fixedly connected to the nut, thereby realizing the linear motion of the working push rod; the stepper motor has a built-in rotary encoder. When the motor shaft rotates, the rotary encoder records the number of rotations, which is converted into linear displacement through the transmission ratio of the screw (for example: the pitch of the screw is 5mm, and it advances 5mm per rotation), realizing the monitoring of the moving distance. During the pushing process, the pressure sensor monitors the pressure value felt by the push head 4. When the pressure or pushing distance felt by the pressure sensor reaches a preset value, the controller controls the electric push rod 2 to pause and maintain a stable period of time (1 minute). The controller then controls the working end of the electric push rod to retract to release the push of the push head on the human neck. After the working end of the electric push rod retracts to a specified displacement and maintains it for a preset time (1 minute), the controller controls the working end of the electric push rod to push out the set displacement again to push the thyroid cartilage on the human neck again and maintain it for a predetermined time (1 minute). This cycle is repeated a specified number of times (about 15 times). It should be noted that during the initial pushing training, a smaller pushing displacement can be set. For example, when the pushing displacement is 110mm, the pushing head only contacts the specified part. The pushing displacement can be set to 115mm. After one or more sets of training, the pushing displacement is gradually increased until the thyroid cartilage can be offset by 1cm from the midline of the neck. Multiple sets of training should be performed every day before surgery to achieve the effect of artificial trachea pushing training.

[0036] The intelligent tracheal pushing training device of the present invention drives the pushing head to push the patient's trachea through an electric push rod, controls the pushing displacement through a controller, and monitors the pushing force through a pressure sensor, which can assist the patient to strictly perform tracheal pushing training according to the requirements, prevent the patient from having poor compliance or forgetting to push or the pushing training is not in place, and at the same time can reduce the workload of medical staff and patients, and the patient can carry out daily life while using it; it can avoid the problem of insufficient or excessive pushing force by the patient himself, which may not achieve the training effect if the pushing force is insufficient, and may cause discomfort reaction and resistance to further training if the pushing force is too large; the surface of the pushing head is concave arc-shaped, which increases the contact area with the neck, and the flexible contact gasket can reduce the discomfort of the patient's neck and reduce the possibility of damage to the skin, soft tissue and trachea; the training device is of integrated design and can be detachably connected to the neck brace. After surgery, the patient only needs the support of the neck brace structure, and the training device can be removed for subsequent preoperative training of other patients. It has high reusability and reduces the patient's consumables cost.

[0037] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
