Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an aerobic exercise assistance device for the head and neck of liver cirrhosis patients. Background Technique

[0002] Liver cirrhosis patients have sarcopenia, and its risk factors are related to motor functions such as progressive and extensive reduction of skeletal muscle mass and strength. The risks of hepatic encephalopathy, infection, and ascites in liver cirrhosis patients with sarcopenia are significantly increased, and the survival rate of such patients after liver transplantation is low, and the hospitalization time, intensive care time, and intubation time after transplantation are all prolonged, affecting the survival outcome of patients after liver transplantation. Therefore, poor motor function leads to an increase in sarcopenia and frailty in decompensated liver cirrhosis patients, aggravating the occurrence of adverse outcomes such as mortality, hospitalization rate, and length of hospital stay, seriously affecting the prognosis of the disease and the quality of life of patients, and bringing a serious disease burden to families and society.

[0003] The exercise interventions for liver cirrhosis patients carried out at home and abroad mainly include aerobic exercise, resistance training (anaerobic exercise), flexibility and balance training, etc., and certain effects have been achieved. Aerobic exercise can increase oxygen uptake in larger muscle groups and is beneficial to the cardiovascular homeostasis of patients. Resistance training mainly affects muscle strength and mass, while flexibility and balance training improve the range of motion required for daily activities and reduce the risk of patients falling. The current places for implementing exercise rehabilitation for liver cirrhosis patients are mainly hospitals and families. Most liver cirrhosis exercise studies focus on interventions in hospitals with the help of expensive exercise equipment. However, this exercise program requires a special venue and professional supervision, takes more time, energy and cost, and is prone to problems such as reduced compliance and difficulty in adhering to the exercise program for a long time. In order to effectively control and quantify the exercise intensity and progress of liver cirrhosis patients, the specific methods of aerobic exercise mostly choose more expensive exercise equipment, mainly aerobic exercise for exercising the limbs, lacking convenient aerobic exercise methods for the head and neck.

[0004] The existing head and neck exercise devices currently require patients to be in a sitting or standing position, and the fixed head is tractioned by a traction device to achieve the effect of head and neck exercise. However, for liver cirrhosis patients, the following problems will exist:

[0005] 1. Liver cirrhosis patients in the decompensated stage need to maintain a supine position to increase the blood flow of the liver and kidneys. However, the existing head and neck exercise devices require customers to maintain a sitting or standing position, and liver cirrhosis patients in the decompensated stage cannot exercise their heads and necks through the existing devices;

[0006] 2. Currently, most head and neck exercise devices cannot adjust the strength of resistance required when the head and neck move. The pressure on the head and neck is the same for patients with different recovery levels. The patient's head and neck may feel uncomfortable because the resistance required when the patient's head and neck move backward is too great, or the patient's head and neck may not be able to achieve the effect of rehabilitation exercise because the resistance required when the patient's head and neck move backward is too small. Utility Model Content

[0007] In order to solve the above problems, the purpose of the utility model is to provide a head and neck aerobic exercise auxiliary device for patients with liver cirrhosis, which can enable patients to exercise their head and neck when they are in a supine position, thereby avoiding as much as possible the reduction of liver and kidney blood flow due to head and neck exercise.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A head and neck aerobic exercise auxiliary device for patients with liver cirrhosis, comprising a pair of clamping assemblies symmetrically arranged on the left and right sides of the front end of a bed board, and a head and neck exercise assembly installed between the two clamping assemblies; the head and neck exercise assembly comprises a mounting plate fixedly arranged between the two clamping assemblies, a sliding subassembly fixedly arranged at the bottom of the mounting plate and sliding along the width direction of the mounting plate, a lifting subassembly transmission-connected to the sliding subassembly at the bottom and arranged along the height direction, a pair of telescopic subassemblies symmetrically fixed on the left and right sides of the upper surface of the lifting subassembly and vertically movably inserted into the mounting plate, and a supporting seat rotatably arranged between the two telescopic subassemblies to support the patient's head and neck; the supporting seat is located at one end of the patient's neck and is rotatably connected to the mounting plate; each group of the telescopic subassemblies comprises an elastic telescopic rod and a mounting seat fixed at the top of the elastic telescopic rod; the two ends of the supporting seat are rotatably connected to the mounting seats in the two groups of telescopic subassemblies respectively; the mounting plate is provided with an avoidance groove along the width direction, and the two elastic telescopic rods pass through the avoidance groove.

[0010] More preferably, the sliding subassembly includes support columns symmetrically and vertically fixed on the left and right sides of the lower surface of the mounting plate, a support plate with two top ends respectively fixedly connected to the bottom of the two support columns, a slide rail embedded in the upper surface of the support plate along the width direction, a slider slidably connected to the slide rail, and a first fixed plate fixed on the top of the slider.

[0011] More preferably, the lifting subassembly includes a pair of linear actuators symmetrically fixed to the left and right sides of the upper surface of the first fixed plate and a second fixed plate with two ends of the bottom respectively fixedly connected to the driving ends of the two linear actuators.

[0012] More preferably, each group of the clamping assemblies includes two clamping plates hinged to each other and a return spring disposed between the pressing ends of the two clamping plates; and both ends of the mounting plate are respectively fixed to the clamping plates in the two groups of clamping assemblies.

[0013] Preferably, a pair of restraint straps are symmetrically and fixedly arranged on the left and right side faces of the support base; one of the restraint straps has a hook surface on its inner side, and the other restraint strap has a flannel surface on its outer side that cooperates with the hook surface.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model can fix the device on the bed board through the clamping assembly, and then, through the cooperation of the mounting plate, the sliding sub-assembly, the telescopic sub-assembly and the support base, an upward supporting force is generated on the head and neck of the patient, so that the patient needs to exert force downward on the head and neck until the support base rotates to be parallel to the mounting seat. During this process, the head and neck need to resist the elastic force of the telescopic sub-assembly to achieve the effect of exercising the head and neck muscles, so that the patient can exercise the head and neck while maintaining a supine position;

[0016] 2. Through the cooperation of the lifting sub-assembly, the telescopic sub-assembly and the support base, when the lifting sub-assembly drives the telescopic sub-assembly upward, the greater the force required for the patient to rotate the support base to a position parallel to the mounting plate through the strength of the head and neck. Thus, the height of the telescopic sub-assembly can be adjusted according to the recovery situation of the patient, so as to avoid the situation that the patient's head and neck are uncomfortable due to excessive resistance required when the patient's head and neck move backward, and also avoid the situation that the patient cannot obtain the effect of rehabilitation exercise due to too little resistance required when the patient's head and neck move backward.

[0026] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] A head and neck aerobic exercise auxiliary device for patients with liver cirrhosis, comprising a pair of clamping components 1 symmetrically arranged on the left and right sides of the front end of a bed board, and a head and neck exercise component 2 installed between the two clamping components 1; the head and neck exercise component 2 comprises a mounting plate 21 fixedly arranged between the two clamping components 1, a sliding sub-component 22 fixedly arranged at the bottom of the mounting plate 21 and sliding along the width direction of the mounting plate 21, a lifting sub-component 23 which is transmission-connected to the sliding sub-component 22 at the bottom and arranged along the height direction, and a pair of telescopic components symmetrically fixed on the left and right sides of the upper surface of the lifting sub-component 23 and vertically movably inserted into the mounting plate 21 The subassembly 24 and the supporting seat 25 which is rotatably arranged between the two telescopic subassemblies 24 to support the patient's head and neck; the supporting seat 25 is located at one end of the patient's neck and is rotatably connected to the mounting plate 21; each group of the telescopic subassemblies 24 includes an elastic telescopic rod 241 and a mounting seat 242 fixed to the top of the elastic telescopic rod 241; the two ends of the supporting seat 25 are rotatably connected to the mounting seats 242 in the two groups of telescopic subassemblies 24 respectively; the mounting plate 21 is penetrated by an avoidance groove 211 along the width direction, and the two elastic telescopic rods 241 telescopic rods pass through the avoidance groove 211.

[0028] The device can be fixed to the bed board through the clamping assembly 1. Subsequently, through the cooperation of the mounting plate 21, the sliding sub-assembly 22, the telescopic sub-assembly 24 and the supporting seat 25, an upward supporting force is generated on the patient's head and neck, so that the patient needs to exert force downward on the head and neck until the supporting seat 25 rotates to be parallel to the mounting seat 21. During this process, the head and neck need to resist the elastic force of the telescopic sub-assembly 24 to achieve the effect of exercising the head and neck muscles, so that the patient can exercise the head and neck while maintaining a supine position; through the cooperation of the lifting sub-assembly 23, the telescopic sub-assembly 24 and the supporting seat 25, when the lifting sub-assembly 23 drives the telescopic sub-assembly 24 upward, the greater the force required for the patient to rotate the supporting seat 25 to a position parallel to the mounting plate 21 through the strength of the head and neck. Thus, the height of the telescopic sub-assembly can be adjusted according to the patient's recovery situation, so as to avoid the situation that the patient's head and neck are uncomfortable due to too much resistance required when the patient's head and neck move backward, and also avoid the situation that the patient cannot get the effect of rehabilitation exercise due to too little resistance required when the patient's head and neck move backward; through the setting of the elastic telescopic rod 241, when the patient pushes the supporting seat 25 to rotate, it resists the elastic force of the elastic telescopic rod 241 to achieve the exercise effect.

[0029] As a possible implementation manner of this solution, preferably, the sliding sub-assembly 22 includes support columns 221 symmetrically and vertically fixed to the left and right sides of the lower surface of the mounting plate 21, a support plate 222 whose two ends at the top are respectively fixed to the bottoms of the two support columns 221, a slide rail 223 embedded in the upper surface of the support plate 222 in the width direction, a slider 224 slidably connected to the slide rail 223, and a first fixing plate 225 fixed to the top of the slider 224; through the cooperation of the slide rail 223 and the slider 224, when the patient's head and neck push the supporting seat 25, it can drive the lifting sub-assembly 23 and the telescopic sub-assembly 24 to move along the thickness direction of the mounting plate 21, avoiding the interference with the rotation of the supporting seat 25 caused by the immovability of the lifting sub-assembly 23 and the telescopic sub-assembly 24 when the patient's head and neck push the supporting seat 25.

[0030] As a possible implementation manner of this solution, preferably, the lifting sub-assembly 23 includes a pair of linear drivers 231 symmetrically fixed to the left and right sides of the upper surface of the first fixing plate 225 and a second fixing plate 232 whose two ends at the bottom are respectively fixed to the driving ends of the two linear drivers 231; through the setting of the linear driver 231, the height of the telescopic sub-assembly 241 can be adjusted, thereby changing the force required for the patient to push the supporting seat 25 to a position parallel to the mounting plate 21 to adapt to the patient's physical condition.

[0031] As a possible implementation manner of this solution, preferably, each clamping assembly 1 includes two clamping plates 11 hinged to each other and a return spring 12 disposed between the pressing ends of the two clamping plates 11; both ends of the mounting plate 21 are respectively fixed to the clamping plates 11 in the two clamping assemblies 1; through the cooperation of the clamping plates 11 and the return spring 12, the device can be fixed to the front end of the bed.

[0032] As a possible implementation manner of this solution, preferably, a pair of restraint straps 3 are symmetrically and fixedly provided on the left and right side surfaces of the supporting seat 25; a hook surface 4 is provided on the inner side surface of one of the restraint straps 3 and a fluff surface 5 cooperating with the hook surface 4 is provided on the outer side surface of the other restraint strap 3; through the arrangement of the two restraint straps 3, the patient's head can be fixed to the supporting seat 25, preventing the patient's head and neck from shifting relative to the supporting seat 25 when the supporting seat 25 is rotated, thereby avoiding sprains caused by the displacement of the patient's head and neck and improving the safety of the device.

[0033] The working principle of this device is as follows:

[0034] Before use, the device is fixed to the front end of the bed through the two clamping assemblies 1, the patient's head and neck are placed in the supporting seat 25, and then the two restraint straps 3 are fixed to the patient's head through the hook surface 4 and the fluff surface 5. Subsequently, the height of the telescopic end of the linear actuator 231 is adjusted according to the patient's recovery condition. The patient drives the supporting seat 25 to rotate to the horizontal plane by the force of the head and neck. During this process, the force of the patient's head and neck will oppose the force of the elastic telescopic rod 241, thus achieving the effect of exercising the head and neck muscles; to ensure the training effect, a mattress needs to be laid on the top of the bed board so that the top of the mattress is flush with the bottom of the supporting seat 25.

[0035] The above are only the specific implementation manners of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
