Description

Technical Field

[0001] This invention relates to the field of medical devices for stroke rehabilitation, specifically a rehabilitation training cap for stroke hemiplegic patients. Background Technology

[0002] Hemiplegia following stroke is often accompanied by sequelae such as limb motor dysfunction, sensory abnormalities, and poor cerebral blood circulation. Traditional Chinese medicine considers the Du meridian to be the "sea of ​​Yang meridians," governing the body's Yang energy. Stimulating acupoints along the Du meridian and Jiaji points can help awaken the mind, clear the meridians, and promote the recovery of limb function. Modern rehabilitation medicine has also confirmed that physical stimulation such as massage and heat therapy on specific acupoints on the head can promote the establishment of collateral circulation in the brain, improve local blood supply to brain tissue, and facilitate neural function remodeling.

[0003] Currently, rehabilitation training equipment for stroke patients with hemiplegia mostly focuses on limb training, such as upper limb rehabilitation robots and lower limb walking trainers. Wearable devices that provide comprehensive physical stimulation of the head's meridians and acupoints are relatively rare. Existing head massage devices are mostly simple vibration massages, and the driving mechanism for the massage movements often uses independent motors, resulting in limited functionality and high energy consumption. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a rehabilitation training cap for stroke patients with hemiplegia. It uses a single servo motor to simultaneously drive a push rod to reciprocate and mechanically press acupoints on the Du meridian, and drives an impeller to rotate to generate airflow, which is then heated to form hot air that stimulates the acupoints on the Du meridian. This achieves synergistic treatment using two physical stimulation modes: pressure and hot air.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A rehabilitation training cap for stroke hemiplegic patients includes a training cap, a training component, a gas circulation component, and a massage and heating component. The training component includes a shell, which is fixedly installed on the rear end of the outer wall of the training cap. Multiple return springs are fixedly connected from top to bottom to the rear end of the inner wall of the outer shell. Each return spring is fixedly connected to a connecting rod at its front end. A hollow groove is opened inside the connecting rod. A servo motor is fixedly installed at the lower part of the rear end of the inner wall of the outer shell. An impeller rod is fixedly connected to the output end of the servo motor. A drive gear is fixedly connected to the rear end of the outer wall of the impeller rod. A driven rod is rotatably connected to the lower part of the inner wall of the housing near the impeller rod and located at both ends. A front driven gear and a rear driven gear are fixedly connected to the front end and rear end of each driven rod, respectively. A transmission gear is rotatably connected to the lower part of the inner wall of the housing near the driven rod and located at both ends. The transmission gear meshes with the front driven gear. A slide rod is fixedly connected to the upper part of the outer wall of the rear end of the transmission gear. A slide frame is slidably connected to the outer wall of the slide rod. A limit frame is fixedly connected to the lower part of the inner wall of the housing near the transmission gear and located at both ends. A push rod is fixedly connected to the upper end of the slide frame through the limit frame. The upper end of the push rod is a wedge-shaped push block. A groove matching the wedge-shaped push block is opened at the lower end of the connecting rod. The gas flow assembly includes a mounting shell, which is fixedly covered by the impeller portion of the impeller rod. An air inlet pipe is fixedly connected to the lower end of the mounting shell. Two flow pipes are connected to both sides of the upper end of the outer wall of the mounting shell. The upper ends of the flow pipes are connected to the hollow groove inside the connecting rod. The massage heating assembly includes three mounting cylinders. The rear ends of the three mounting cylinders are all connected to the hollow groove in the connecting rod from top to bottom. Massage heads are fixedly connected to the front ends of the three mounting cylinders. The massage heads are located at the Du meridian acupoints. Each massage head has a through groove at its front end. Multiple heating rods are fixedly connected to the inner wall of each through groove. A temperature monitor is installed at the front end of each through groove. Filters are installed on the inner walls of the massage heads and the air inlet pipe to prevent the entry of external dust and impurities.

[0006] Through the above technical solution, a single servo motor drives the impeller rod to rotate. On one hand, the rotational motion is converted into the up-and-down reciprocating motion of the push rod through a gear transmission chain of the driving gear, driven gear, and transmission gear. The push rod engages with the inclined groove at the lower end of the connecting rod through a wedge-shaped push block, and with the help of a return spring, the connecting rod achieves the back-and-forth reciprocating motion, thereby driving the massage head to mechanically press the Du meridian acupoints. On the other hand, the impeller part on the impeller rod rotates in the mounting housing to generate airflow. The airflow enters the hollow groove in the connecting rod through the flow pipe, then enters the through groove in the massage head through the mounting cylinder. After being heated by the heating rod, it is blown out as hot air to stimulate the Du meridian acupoints.

[0007] Furthermore, the driving gear meshes with the driven gear at the rear end, and the driven gear at the rear end drives the driven gear at the front end to rotate synchronously. The driven gear at the front end drives the slide rod to rotate around the axis of the transmission gear via the transmission gear. The slide rod drives the slide frame to slide up and down vertically within the limiting frame, and the push rod moves up and down synchronously with the slide frame. Through the above technical solution, the meshing of the driving gear and the rear driven gear realizes the first-level transmission, and the meshing of the front driven gear and the transmission gear realizes the second-level transmission. The two-level transmission converts the high-speed rotational motion of the servo motor into the low-speed reciprocating linear motion of the push rod.

[0008] Furthermore, when the push rod moves upward, the wedge-shaped push block at the upper end of the push rod wedges into the inclined groove at the lower end of the connecting rod, pushing the connecting rod backward, and the return spring is compressed; When the push rod moves downward, the wedge-shaped push block moves down along the inclined groove, and the return spring rebounds to push the connecting rod forward to press the Du meridian acupoint, which is used for the massage head to reciprocate the pressure on the Du meridian acupoint; Through the above technical solution, the cooperation between the wedge-shaped pusher and the inclined groove transforms the vertical motion of the push rod into the horizontal motion of the connecting rod, and the return spring provides the return force of the connecting rod, forming the reciprocating motion of the connecting rod.

[0009] Furthermore, when the impeller rod rotates, the impeller portion on it rotates within the mounting housing to generate airflow. External air enters the mounting housing through the air inlet pipe, and the airflow enters the hollow groove inside the connecting rod through the flow pipe, and then enters the through groove inside the massage head through the mounting cylinder. When the airflow flows through the heating rod, it is heated into hot air, and the hot air is blown out from the front end of the through groove to stimulate the Du meridian acupoints with hot air. The above technical solution allows the air supply function and the pressing function to share the same power source, resulting in a compact structure. Hot air is blown out from the groove at the front of the massage head, directly acting on the skin surface of the Du meridian acupoints to warm and unblock the Du meridian.

[0010] Furthermore, the temperature monitor detects the temperature of the hot air blown out from the front end of the channel in real time and feeds the temperature signal back to the control system. The control system adjusts the heating power of the heating rod according to the feedback signal to maintain the hot air temperature at 40°C to 50°C. Through the above technical solutions, closed-loop temperature control ensures that the hot air temperature remains constant within a safe and comfortable range, avoiding excessively high temperatures that could burn the patient's scalp or excessively low temperatures that would fail to achieve the desired warming and stimulating effect.

[0011] Furthermore, the front end face of the massage head is an arc-shaped concave surface, and the arc-shaped contour matches the curvature of the human scalp; Through the above technical solution, the arc-shaped concave surface makes the massage head fit more closely to the scalp, increases the contact area when pressing, distributes pressure evenly, and improves massage comfort.

[0012] Furthermore, the massage head corresponds to the Baihui, Fengfu and Dazhui acupoints respectively from top to bottom along the Du meridian of the training cap; the heating rod is a PTC ceramic heating rod or a resistance miniature heating rod; and the temperature monitor is a miniature thermocouple or a thermistor. Through the above technical solution, the three massage heads correspond to three key acupoints on the Du meridian, achieving precise positioning and stimulation of the acupoints. The PTC ceramic heating rod has self-limiting temperature characteristics and high safety.

[0013] Furthermore, the inner diameter of the front driven gear is smaller than the inner diameter of the rear driven gear, the inner diameter of the driving gear is the same as the inner diameter of the front driven gear, and the inner diameter of the transmission gear is the same as the inner diameter of the rear driven gear. Through the above technical solution, the diameter difference between the front driven gear and the rear driven gear forms the first stage of deceleration, and the diameter difference between the front driven gear and the transmission gear forms the second stage of deceleration. The two-stage gear deceleration transforms the high-speed rotation of the servo motor into the low-speed, high-thrust reciprocating motion of the push rod.

[0014] This invention provides a rehabilitation training cap for stroke patients with hemiplegia. It has the following beneficial effects: 1. This invention provides a rehabilitation training cap for stroke hemiplegic patients. It uses a single servo motor to simultaneously drive a mechanical pressing mechanism and an air supply and heating mechanism. The impeller rotates to generate airflow while driving the massage head to press back and forth through a gear transmission chain. One power source realizes two therapeutic functions: pressing and hot air. It has a compact structure and low energy consumption.

[0015] 2. This invention provides a rehabilitation training cap for stroke hemiplegic patients. By combining non-contact hot air stimulation with mechanical pressure stimulation, the hot air is blown out through the groove at the front end of the massage head and directly acts on the Du meridian acupoints to warm and unblock the Du meridian and promote blood circulation in the brain. At the same time, the massage head reciprocates and presses the acupoints. The two physical stimulation modes work synergistically to provide comprehensive acupoint treatment for stroke hemiplegic patients. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0019] like Figure 1-9 As shown, this embodiment of the invention provides a rehabilitation training cap for stroke hemiplegic patients, including a training cap 1, a training component 2, a gas circulation component 3, and a massage and heating component 4.

[0020] The training cap 1 is a wearable cap designed to be fixed to the patient's head. The training component 2 includes an outer shell 21, which is fixedly installed at the rear end of the outer wall of the training cap 1, corresponding to the back of the patient's head. Three return springs 22 are fixedly connected from top to bottom to the rear end of the inner wall of the outer shell 21. A connecting rod 23, a rectangular metal rod, is welded and fixedly connected to the front end of each return spring 22. A hollow groove with a rectangular cross-section is formed inside the connecting rod 23 along its length.

[0021] A servo motor 24 is bolted to the lower part of the rear end of the inner wall of the outer casing 21. The output end of the servo motor 24 is fixedly connected to an impeller rod 25 via a coupling. A drive gear 26 is fixedly connected to the rear end of the outer wall of the impeller rod 25 via a key.

[0022] A driven rod 27 is rotatably connected to the lower part of the inner wall of the housing 21, near the impeller rod 25 and at both ends. Driven gears 28 are fixedly connected to the front and rear ends of the driven rod 27 via keys. The inner diameter of the front driven gear 28 is smaller than that of the rear driven gear 28, and the inner diameter of the driving gear 26 is the same as that of the front driven gear 28. The driving gear 26 meshes with the rear driven gear 28 for transmission.

[0023] A transmission gear 29 is rotatably connected to the lower part of the inner wall of the housing 21, near the driven rod 27 and located at both ends. The inner diameter of the transmission gear 29 is the same as the inner diameter of the rear driven gear 28. The transmission gear 29 meshes with the front driven gear 28. A slide rod 211, which is a short cylindrical shaft, is welded and fixed to the upper part of the outer wall of the rear end of the transmission gear 29. A slide frame 210 is slidably connected to the outer wall of the slide rod 211. The slide frame 210 is a metal frame with an elongated groove inside that slides with the slide rod 211.

[0024] A limit frame 212 is welded and fixed to the lower part of the inner wall of the housing 21, near the transmission gear 29 and at both ends. The limit frame 212 is a rectangular frame structure. The upper end of the slide 210 passes through the top through hole of the limit frame 212 and is welded and fixed to a push rod 213. The upper end of the push rod 213 is machined with a wedge-shaped push block, and the lower end of the connecting rod 23 is provided with an inclined groove that matches the wedge-shaped push block.

[0025] The gas flow assembly 3 includes a mounting housing 31, which is a volute-shaped metal shell fixedly covering the impeller portion of the impeller rod 25. An inlet pipe 32 is fixedly connected to the lower end of the mounting housing 31, extending downwards through the bottom of the outer shell 21 to communicate with the outside atmosphere. Two flow pipes 33, which are flexible hoses, are connected to both sides of the upper end of the outer wall of the mounting housing 31. The upper ends of the four flow pipes 33 are respectively connected to the hollow grooves inside the connecting rod 23.

[0026] The massage heating assembly 4 includes three mounting cylinders 41, the rear ends of which are connected from top to bottom to the hollow grooves in the connecting rod 23. Massage heads 42 are fixed to the front ends of the three mounting cylinders 41. The three massage heads 42, running along the Du meridian of the training cap 1 from top to bottom, correspond to the Baihui, Fengfu, and Dazhui acupoints on the patient's head, respectively.

[0027] The front end of the massage head 42 is a concave arc shape, with its arc contour matching the curvature of the human scalp. Each massage head 42 has a through-slot 43 at its front end, which is a circular cross-section channel. Multiple heating rods 44, PTC ceramic heating rods with self-limiting temperature characteristics, are evenly distributed and fixedly connected to the inner wall of the through-slot 43 along its circumference. Each through-slot 43 has a temperature monitor 45, which is a miniature thermocouple, used to monitor the temperature of the hot air blown from the front end of the through-slot 43 in real time.

[0028] Work process: The patient wears the training cap 1 on their head, and the elastic band is used to fit snugly against the chin so that the back of the training cap 1 fits against the back of the head, and the front arc-shaped concave surfaces of the three massage heads 42 fit against the Baihui, Fengfu and Dazhui acupoints respectively.

[0029] The servo motor 24 is started, and the servo motor 24 drives the impeller rod 25 to rotate. The rotation of the impeller rod 25 simultaneously drives two subsystems to work: Mechanical pressing subsystem: The driving gear 26 rotates with the impeller rod 25, and through meshing with the rear driven gear 28, drives the driven rod 27 to rotate. The driven rod 27 drives the front driven gear 28 to rotate synchronously, and the front driven gear 28, through meshing with the transmission gear 29, drives the transmission gear 29 to rotate. The slide rod 211 on the transmission gear 29 moves in a circular motion around its axis with the transmission gear 29. The slide rod 211 slides within the elongated hole of the slide 210, driving the slide 210 to slide vertically up and down within the limiting frame 212. The push rod 213 moves up and down synchronously with the slide 210.

[0030] When push rod 213 moves upward, the wedge-shaped push block at the upper end of push rod 213 wedges into the inclined groove at the lower end of connecting rod 23, pushing connecting rod 23 backward, and compressing return spring 22. When push rod 213 moves downward, the wedge-shaped push block moves down along the inclined groove and exits the groove, and return spring 22 rebounds, pushing connecting rod 23 forward. Connecting rod 23 drives mounting cylinder 41 and massage head 42 to move forward, and the arc-shaped concave surface at the front end of massage head 42 presses against the corresponding acupoints. This cycle repeats, and the three massage heads 42 continuously reciprocate the pressure on Baihui, Fengfu, and Dazhui acupoints.

[0031] Hot air stimulation subsystem: The impeller portion on the impeller rod 25 rotates within the mounting housing 31, drawing in external air through the air inlet pipe 32. The airflow then enters the hollow groove inside the connecting rod 23 via the flow pipe 33. The airflow flows forward along the hollow groove, passing through the mounting cylinder 41 and entering the through groove 43 within the massage head 42. As the airflow passes through the through groove 43, it is heated into hot air by the heating rod 44. The hot air is blown out from the front end of the through groove 43, directly acting on the skin surface of the corresponding acupoints. The filter screen 46 prevents the entry of external dust and impurities.

[0032] Temperature monitor 45 detects the temperature of the hot air blown from the front end of the channel 43 in real time and feeds the temperature signal back to the control system. The control system adjusts the heating power of the heating rod 44 according to the feedback signal to keep the hot air temperature stable between 40℃ and 50℃. The hot air is continuously blown on the acupoints while the massage head 42 is reciprocating, realizing the synergistic treatment of the two physical stimulation modes of pressure and hot air.

[0033] The following points should be noted in this article: 1. The accompanying drawings of the embodiments disclosed herein only relate to the structures involved in the embodiments disclosed herein; other structures can be referred to in a general design.
