Description

Technical Field

[0001] The present invention belongs to, but is not limited to, the technical field of medical devices, and particularly relates to a glove device for a hand fixing instrument based on airbag locking and a control method therefor. Background Art

[0002] Early restraint gloves mostly adopted traditional binding methods. Although they could effectively restrict the movement of both hands, they often brought discomfort to the operator and it was also difficult to provide a switch between restraint and free movement.

[0003] With the continuous progress of industrial technology, processing equipment, and wearable technology, and the improvement of medical care standards, people began to explore more effective and safe hand restraint devices.

[0004] For example, in medical applications, during the diagnosis and treatment process when a doctor holds an endoscope; in the precision measurement industry, when an engineer holds a measuring instrument or high-value optical or metal parts for measurement and installation, long-term work may cause hand fatigue or minute tremors, thus seriously interfering with the handheld instrument equipment. In some cases, hand strain and injury may also occur due to improper operation or accidental situations. At this time, engineering restraint gloves can be used to fix and restrain the movement of the hand, providing additional support and protection. In the ICU, patients may need to restrict the movement of their hands due to confusion, restlessness, or treatment needs. Such restraint gloves can also effectively prevent patients from performing dangerous actions such as pulling out important therapeutic tubes, such as arteriovenous access, nasogastric tube, oxygen tube, urinary catheter, etc.

[0005] In view of the above analysis, the technical problem urgently to be solved in the prior art is that early restraint gloves mostly adopted traditional binding methods. Although they could effectively restrict the movement of both hands, they often brought discomfort to the operator and it was also difficult to provide a switch between restraint and free movement. Summary of the Invention

[0006] Aiming at the problems existing in the prior art, the present invention provides a glove device for a hand fixing instrument based on airbag locking, which can accurately lock the finger joints and wrist joints without causing discomfort to the hand, and can protect the hand and assist in performing accurate operations when the user wears it.

[0007] The present invention is implemented as follows: a glove device for hand fixing instruments based on airbag locking, which is composed of a glove body, an annular airbag, an annular friction device, a gas storage bottle, an air pump, an air pump control device, a voice control device, a snake bone device, etc. The inner side of the glove body is made of high friction material to ensure close contact with the device during use. Snake bone material is added to the finger part of the glove body to provide certain protection for the fingers, and the durability of the glove body is improved without hindering the movement of the finger joints. The moisture in the gas storage bottle is discharged through the bottom drain valve to prevent the pipeline from freezing. A safety valve and a pressure sensor are set to automatically release the pressure when the air pressure exceeds the set value, and trigger an alarm device when the air pressure is too low. A one-way valve is used to transmit air to prevent the compressed air from flowing back. The gas storage bottle is equipped with a strap, which does not affect the hand operation during operation. The snake bone consists of multiple sections, each of which is bent around the finger joint. Adding a snake joint device to the annular airbag can enhance the strength of the annular airbag and achieve better fixing effect. The annular airbags are located inside the five fingers of the glove body and at the arm joints. After inflation, they lock the fingers and arms respectively to ensure the stability of the work. The air pump control device adopts a voice control mode, accepts the user's voice command through the voice recognition module, and controls the switch of the electric valve. The specific operation is that the voice recognition module accepts the command, the single-chip microcomputer analyzes the output signal of the language recognition module, and controls the switch of the electric valve according to the analysis result. The voice control device can select the number of inflations. As the number of inflations increases, the degree of locking increases.

[0008] Furthermore, the glove device for hand-fixed instruments based on airbag locking can be operated with one hand during use. The modes include idle, inflated, deflated, and locked states. The command to release the locked state needs to be repeated three times before it can be executed. The snake-bone joint device can be designed as a tubular structure with inflatable annular airbag pipes running through both sides. After inflation, the whole expands. The expansion of the annular airbag squeezes the contact surface of the adjacent joints, and limits the relative movement of the joints by increasing the friction. A Y-shaped structure is formed between the buckles of the snake-bone joint device. After inflation, the contact pressure increases sharply, forming a rigid lock. That is, it can be ensured that the fingers cannot move even in the locked state.

[0009] Furthermore, when operating the equipment using the hand-fixed instrument glove device based on airbag locking, first put the air pump control device in an idle state and let the hand complete the operation of the target; put the air pump control device in an inflated state, turn on the air compressor, and the air compressor rotates to drive the piston downward. The air in the gas cylinder enters the cylinder through the air filter and the intake valve. When the piston moves upward, the air in the cylinder is compressed and the pressure increases. In order to overcome the pre-tightening force of the exhaust valve, the exhaust valve is opened, and the compressed air enters the annular airbag, and sufficient air pressure is filled into the annular airbag. The annular airbag becomes hard and can fix the joint; after use, adjust the air pump control device to a deflated state, open the finger sleeve exhaust valve, and the annular airbag returns to its original state, so that the joint can move freely.

[0010] Furthermore, when the patient wears it, it can be adjusted to a locked state after the inflation state is completed, with the hands completely fixed and the air pump control device cannot be adjusted by the patient.

[0011] The present invention also provides a control method for a hand-fixing instrument glove device based on airbag locking, comprising the following steps:

[0012] (1) Recognize the user's voice command, receive the control signal through the voice recognition module, and analyze the output signal by the single chip microcomputer;

[0013] (2) According to the analysis results, the switch of the electric valve is controlled to realize the inflation or deflation operation of the annular airbag;

[0014] (3) During the inflation process, the air compressor rotates, driving the piston downward, allowing air to enter the cylinder through the air filter and the intake valve, and compressing the air as the piston moves upward. The compressed air then enters the annular airbag through the one-way valve, causing the annular airbag to inflate and expand, thereby achieving hand locking and fixation;

[0015] (4) During the deflation process, open the finger sleeve exhaust valve to restore the annular airbag to its original shape so that the joint can move freely.

[0016] Further, the method includes a locking mode, where after inflation is complete, the user can select a locking state to completely immobilize the hand;

[0017] In the locked state, the device cannot respond to general voice commands. Only after the voice command is repeated three times can the locked state be released and the hands can be free to move.

[0018] Furthermore, during use, the water in the gas cylinder is discharged through the bottom drain valve to prevent the pipeline from freezing;

[0019] When the air pressure inside the annular airbag exceeds the set value, the pressure sensor triggers the safety valve to automatically release pressure;

[0020] When the air pressure is lower than the set value, the alarm device automatically triggers a warning signal to remind the user to inflate.

[0021] Further, the method includes a one-handed control mode, where the user can switch between the idle, inflated, deflated and locked modes through voice commands;

[0022] During the inflation process, the number of inflation times can be set. Each additional inflation will increase the locking degree accordingly to meet different fixing requirements.

[0023] In combination with the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solutions to be protected by the present invention are as follows:

[0024] This device is made of flexible materials to ensure that it will not cause discomfort to the hand during long-term wear and at the same time achieve full coverage fixation of the hand. The inner side of the glove body is made of high-friction materials to ensure close fitting with the hand in different environments and prevent slipping. In addition, the addition of the snake bone joint structure provides additional support while maintaining a certain degree of flexibility, so that users will not be overly restricted during operation, thus enhancing the wearing experience.

[0025] This device allows the hand to quickly switch between free movement and fixation, suitable for different scenario requirements. In any state, the glove body can activate the fixation function through the voice control mode without manual operation, making it particularly suitable for medical and industrial scenarios, such as surgeons who need to precisely fix the hand during surgery or industrial engineers performing precision assembly work. In addition, the device can achieve zonal fixation of fingers and wrists locally or globally, improving the stability of operation.

[0026] Traditional fixation devices often take a long time to adjust. The annular airbag system of this invention is distributed at the finger and wrist joints, making the fixation process more precise. Through the intelligent control system, users can switch the hand state from free movement to fixation in a short time and can quickly release it through voice commands. This technology not only improves the response speed but also reduces the inconvenience of manual adjustment and improves the operation efficiency.

[0027] This device provides an optional "lock mode". After the device enters the locked state, users need to repeat the voice command multiple times to unlock it, preventing accidental unlocking caused by misoperation. For example, in medical applications, when a patient wears the glove body for fixation, this function can prevent the patient from accidentally unlocking due to unconscious movement or external interference, thus improving safety. Similarly, in industrial applications, this function can ensure that the fixation state will not be released due to accidental touch during the execution of high-precision tasks, ensuring the stability and safety of work.

[0028] Different from traditional fixation devices that rely on manual adjustment, this device adopts an advanced voice control system, enabling users to control the fixation or release state through voice without using hand operations. This technology greatly improves the operation convenience, especially suitable for scenarios where free hand operation is required, such as doctors operating instruments in a sterile environment or technicians using fixation devices during high-precision assembly. In addition, the device allows users to freely adjust the number of inflations to control the fixation force, making it suitable for scenarios with different binding force requirements.

[0029] This device comes with a built-in gas storage cylinder, and is equipped with a safety valve and a pressure sensor to ensure that the airbag pressure always remains within a safe range. A drain valve is provided at the bottom of the gas storage cylinder, which can effectively drain moisture and prevent the pipeline from freezing due to low temperature environment, thus affecting its use. In addition, this device uses a check valve to prevent the reverse flow of compressed air and avoid misoperation during system pressure fluctuations. The gas storage cylinder is designed with an adjustable shoulder strap for easy user carrying, enabling the device to maintain efficient operation in different application environments.

[0030] This invention can be divided into two main versions, namely the medical version and the industrial version, according to the application scenarios, and the single set price of each version will be different. In the medical field, this device can be applied to rehabilitation treatment, patient hand fixation and surgical assistance, meeting the hospital's need for high-precision fixation equipment; in the industrial field, this device can reduce the impact of hand jitter on precision operations and improve the operation stability of engineers or technicians. Since the core components of this device (such as micro air pumps, sensors, etc.) can be purchased in batches, the production cost will be significantly reduced as the scale expands, and it has strong market competitiveness. In addition, the initial market positioning is in the medical field, which can quickly establish brand credibility, and then expand to the industrial field to open up a broader market growth space.

[0031] Currently, the hand fixation devices on the market mainly rely on rigid structures such as mechanical straps, splints or plasters, lacking dynamic adjustment and intelligent control functions. This invention combines a voice control system, a single-chip microcomputer control and an electric valve to achieve precise locking and flexible switching of finger and wrist joints, making the fixation device more intelligent. In addition, the existing airbag fixation technology is often limited to specific fields such as medical treatment and rehabilitation, while this invention has cross-industry applicability and can meet the dual needs of medical and industrial fields. For example, in the medical field, this device can be used to prevent patients from pulling out tubes, rehabilitation training or surgical assistance, while in the industrial field, it can be used to reduce the impact of hand jitter on precision assembly work, thus filling the market gap of cross-industry fixation equipment.

[0032] There are huge differences in the requirements for fixation equipment between medical and industrial applications. For example, in medical application scenarios, the binding force is usually required not to exceed 20N to prevent blood circulation from being blocked due to excessive compression, while in industrial applications (such as precision machinery operation), a higher binding force of 50 - 100N may be required to offset the impact of minute hand vibrations on operation accuracy. This invention enables users to freely choose an appropriate locking strength according to different needs through an adjustable inflation system, achieving the adaptability of the same device in different scenarios, which has not been effectively solved in traditional fixation equipment.

[0033] The present invention uses a combination of an annular airbag and a snake-bone joint device to successfully achieve accurate fixation of multiple joints of the hand (fingers + wrist). Compared with traditional single-point fixed devices, the split annular airbag structure of the present invention can be adapted according to the hand shape of different users to ensure that the fingers and wrists are stably supported at the same time. In addition, the snake-bone joint structure allows natural bending while ensuring fixation, avoiding the hand stiffness problem that may be caused by traditional rigid fixing devices, and improving the user experience and comfort.

[0034] Traditional fixing devices require users to manually adjust the tightness of the straps, while the present invention realizes intelligent operation through a voice control system, allowing users to adjust the fixing state more conveniently. In addition, the device provides multiple operating modes, including idle, inflation, deflation and locking modes, and users can switch freely according to their needs. At the same time, the device uses voice commands to adjust the degree of fixation, allowing users to accurately control the strength of hand locking and effectively adapt to different usage scenarios.

[0035] This device uses a number of safety measures to ensure user safety. First, the bottom of the gas cylinder is equipped with a drain valve to effectively prevent the gas line from freezing and affecting the operation of the device; second, the device is equipped with a safety valve and a pressure sensor to ensure automatic pressure relief when the air pressure is too high to prevent the airbag from being damaged by overinflation. In addition, the device uses a setting that repeats the voice command three times to release the lock mode, avoiding accidental unlocking due to mis-touch, thereby improving the reliability of the device. In both the medical and industrial fields, this design can effectively reduce the risk of misoperation and improve overall safety of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0043] like Figure 1 , Figure 2 As shown, the device includes a glove body 3, an annular airbag 6, an annular friction device 7, a gas cylinder 5, an air pump 4, an air pump 4 control device, a voice control device 8, a snake bone device, etc. The inner side of the glove body 3 is made of high friction material to ensure close contact with the device during use. The glove body 3 adds snake bone material to the finger part to provide certain protection for the fingers, and improves the durability of the glove body without hindering the movement of the finger joints. The moisture in the gas cylinder 5 is discharged through the bottom drain valve to prevent the pipeline from freezing. A safety valve and a pressure sensor are set. When the air pressure exceeds the set value, the pressure is automatically released, and the alarm device is triggered when the air pressure is too low. A one-way valve is used to transmit air to prevent the compressed air from flowing back. The gas cylinder 5 is equipped with a strap, which does not affect the hand operation during operation. The snake bone consists of multiple sections, each of which is bent around the finger joint. Adding thin iron wire to the annular airbag 6 can strengthen the strength of the annular airbag 6 and achieve better fixing effect. The annular airbag 6 is respectively located inside the five fingers of the glove body 3 and at the arm joints. After inflation, the fingers and arms are locked respectively to ensure the stability of the work. The air pump 4 control device adopts a voice control mode, which accepts the user's voice command through the voice recognition module to control the switch of the electric valve. The specific operation is that the voice recognition module accepts the command, the single-chip microcomputer analyzes the output signal of the language recognition module, and controls the switch of the electric valve according to the analysis result. The voice control can select the number of inflations. As the number of inflations increases, the degree of locking increases. During use, one-handed control can be achieved, and compared with other manual control devices, precise control can be achieved. The modes include idle, inflation, deflation, and locked states. The command to release the locked state needs to be repeated three times before it can be executed.

[0044] When using the device to operate the equipment, first put the air pump 4 control device in an idle state and let the hand complete the operation of the target; put the air pump 4 control device in an inflated state, turn on the air compressor, the air compressor rotates, drives the piston to press down, and the air in the gas cylinder enters the cylinder through the air filter and the intake valve. When the piston moves upward, the air in the cylinder is compressed and the pressure increases. In order to overcome the pre-tightening force of the exhaust valve, the exhaust valve is opened, and the compressed air enters the annular airbag 6, and sufficient air pressure is filled into the annular airbag 6. The annular airbag 6 becomes hard and can fix the joint; after use, adjust the air pump 4 control device to a deflated state, open the finger sleeve exhaust valve, the annular airbag 6 returns to its original state, and the joint can move freely.

[0045] When the patient wears it, it can be adjusted to a locked state after the inflation is completed, with the hands completely fixed and the patient being unable to adjust the air pump 4 control device.

[0046] As Figure 3 shown, say the command to trigger the voice-activated switch 5, and the air pump 4 starts to work, inflating the annular airbag 6 through the gas pipeline 2; after repeating the deflation command three times, start the valve to deflate.

[0047] After the annular airbag 6 bulges, the external protrusions generate friction with the peripheral annular friction device 7, making it difficult for the fingers and wrist joints to rotate, achieving the effect of fixing the hand and reducing unnecessary movement. After use, control the voice-activated switch 5 on the palm again through a voice command to deflate.

[0048] As Figure 4 shown, the joint locking device 1 is composed of an annular airbag 6 and an annular friction device 7.

[0049] In the intensive care unit (ICU), rehabilitation department, and psychiatric wards of hospitals, some patients may pull out important treatment catheters, such as oxygen tubes, intravenous infusion tubes, urinary catheters, etc., due to confusion, restlessness, or involuntary movements. Traditional restraint methods usually use straps or restraint belts, which are likely to cause skin damage to the patient's wrists and even affect blood circulation. The present invention adopts an annular airbag fixation technique to lock the patient's hand by inflation, making it impossible for the patient to perform fine movements, but still retaining a certain degree of comfort, avoiding discomfort caused by forced restraint. Especially during postoperative recovery, ICU treatment, and neurological disease rehabilitation, this device can be used as a non-invasive restraint tool to ensure the safety of treatment catheters, while reducing the burden on nursing staff and improving medical safety.

[0050] During long surgical procedures, surgeons need to maintain a highly stable hand state. Especially during high-precision medical procedures such as microsurgery, endoscopic surgery, and laser treatment, slight hand tremors may affect the surgical outcome. The adjustable locking function of the present invention allows the doctor to select an appropriate fixation intensity during the operation to reduce hand microtremors caused by fatigue. At the same time, the annular friction device provides additional support at the finger and wrist joints, enabling the doctor to maintain stability during high-precision operations without affecting joint flexibility. This design helps to improve the success rate of surgery and is particularly suitable for high-precision surgical fields such as neurosurgery, ophthalmology, and cardiac surgery.

[0051] In industries such as semiconductor manufacturing, optical lens assembly, and precision instrument manufacturing, workers need to perform high-precision operations at the sub-millimeter level within a very small working space. Minor hand tremors may affect product quality. The intelligent adjustable fixing function provided by the present invention enables the operator to enable the airbag fixing mode when high stability is required, reducing tremors caused by muscle fatigue or nervousness. At the same time, the device can adjust the fixing force according to the work requirements, ensuring hand stability while not affecting the necessary flexibility. Compared with traditional handrests or mechanical bracket fixing methods, the present invention is more convenient, suitable for hands of different sizes and shapes, and improves operation comfort and efficiency.

[0052] In high-intensity sports such as mountaineering, rock climbing, and extreme off-road, the hands and wrist joints are under long-term pressure and are prone to overuse injuries such as muscle fatigue and tenosynovitis. The present invention can be used as a sports assistance device. When athletes or outdoor enthusiasts need to maintain a grasping action for a long time, it provides appropriate support through the annular airbag, reducing the burden on hand muscles and lowering the risk of injury. In addition, in the event of an accidental fall or sudden danger, the device can be instantaneously inflated, enabling the hand to quickly enter a protected state and reducing the probability of joint injury. This application is particularly suitable for professional mountaineers, rock climbers, and outdoor explorers, providing them with additional safety protection.

[0053] For patients with impaired hand function caused by diseases such as stroke, brain injury, and Parkinson's disease, the present invention can be used as a rehabilitation training assistance device. The adjustable airbag fixing system of the device allows patients to gradually increase or decrease the degree of hand movement limitation according to their own recovery situation, enabling them to carry out rehabilitation training within a safe and controllable range. For example, when patients perform hand rehabilitation movements such as grasping and pinching, they can set different fixing intensities through the voice control device to ensure the stability of action execution and prevent uncontrolled hand tremors from affecting the training effect. In addition, the device can combine with neurological rehabilitation therapy to help patients re-establish hand muscle control ability through specific pressure feedback, accelerating the rehabilitation process.

[0054] In some high-risk industrial environments (such as chemical laboratories, high-temperature furnace operations, heavy machinery control, etc.), operators need to maintain hand stability while avoiding safety accidents caused by misoperations. The lockable glove body of the present invention can provide additional stability during dangerous operations, preventing the hands of workers from shaking when operating precision equipment or accidentally touching control buttons when performing high-risk tasks. In addition, the voice control operation function of the device enables the operator to switch the fixing degree of the hand according to needs without directly using the hand for adjustment, thereby improving work safety. For tasks that require a long-term stable grasping posture (such as welding, precision engraving, etc.), this device can effectively reduce muscle fatigue and improve the operation quality.

[0055] Such as Figure 5As shown, the glove is a double-layer airbag. When the glove is activated and fixed, the gas cylinder inflates the airbag, and the airbags on both sides bulge, clamping both ends of the Y-shaped structure, so that the head of the Y-shaped structure clamps the tail of the front Y-shaped structure, achieving a fixing effect.

[0056] In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more; the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, terms such as "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0057] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention by those skilled in the art within the technical scope disclosed by the present invention shall be covered by the protection scope of the present invention.
