Description

Technical Field

[0001] The present invention relates to the technical field of medical care equipment, and in particular to a non-constrained intervention glove for reducing the gripping ability of a patient's hand. Background Art

[0002] Traditional restraint gloves completely restrict hand movement to prevent patients from grasping catheters or wounds, but they present several significant drawbacks. Physiologically, rigid restraints can easily cause skin pressure sores and impede blood circulation, and long-term wear can also cause limb swelling. Psychologically, restricted movement can lead to anxiety, fear, and even resistance in patients, which can reduce treatment compliance. Nursing care requires frequent checks and adjustments of restraint tightness, significantly increasing the workload of medical staff. Existing technologies lack non-constraint solutions that can both limit dangerous grasping behaviors and preserve basic hand mobility. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides a non-constrained intervention glove for reducing the patient's hand grasping ability. Through the combination of flexible limiting and intelligent alarm, it can effectively prevent the patient from grasping or raising his hands unconsciously, causing damage to the face; and when the patient makes a grasping or raising hand action, it can promptly remind the accompanying personnel to adjust the patient's posture, thereby ensuring the patient's safety while reducing physical and psychological damage and reducing the nursing burden of the accompanying personnel.

[0004] The technical solutions of the present invention are as follows:

[0005] A non-constraining intervention glove for reducing a patient's hand gripping ability comprises a glove body and a silicone intervention component. The glove body comprises a flexible mesh sleeve and a buckle connected to the flexible mesh sleeve. The silicone intervention component comprises an anti-grip portion and a collar. The anti-grip portion and collar are integrally formed. The anti-grip portion is located on the palm side of the glove body, and the collar is connected to the anti-grip portion at both ends to form a closed ring structure. The collar is placed over the palm or fingers.

[0006] Furthermore, the glove body is made of nylon braided material.

[0007] Furthermore, the flexible mesh is a double-layer elastic, breathable mesh, providing both breathability and elasticity. The buckle is located at the wrist of the glove body to accommodate different wrist circumferences. The buckle is adjustable using Velcro or a snap-on design. The glove body covers the palm and fingers, limiting grip range while allowing for free rotation and slight flexion and extension of the wrist.

[0008] Furthermore, the shape of the anti-grip portion is semicircular or finger-shaped; when the anti-grip portion is semicircular, the ring is a palm ring; when the anti-grip portion is finger-shaped, the ring is a finger ring. The anti-grip portion fits the physiological curvature of the palm.

[0009] Furthermore, the non-constraining intervention glove also includes a control unit, which includes a pressure sensor, an alarm module, an infrared ranging module, a signal converter, connecting cables, and a main power supply. The signal converter is connected to the pressure sensor, alarm module, and infrared ranging module via connecting cables; the signal converter is also connected to the main power supply. The control unit is located within the silicone intervention component or within the interlayer of the flexible mesh sleeve.

[0010] Furthermore, the pressure sensor is arranged inside the anti-grip portion;

[0011] The signal converter and the alarm module are both arranged on the back of the glove body; the alarm module is a micro buzzer or an LED indicator light;

[0012] The infrared ranging module includes a transmitter and a reflector, wherein one of the transmitter or the reflector is arranged on the outside of the first metacarpal joint of the glove body close to the palm, as well as on the pads of the index finger, middle finger, ring finger, and little finger. When in use, the other one of the reflector or the transmitter is arranged on the face of the glove wearer in the form of a patch. This ensures that the infrared ranging module accurately measures the distance between the patient's hand and face, avoiding false detection of the hand and other parts and issuing an alarm.

[0013] Furthermore, the main power supply is a button battery, and a switch is provided on the main power supply.

[0014] Furthermore, the working principle of the non-constrained intervention glove for reducing the patient's hand grip ability is as follows: after the patient wears the glove, the range of movement of the finger is restricted, but the wrist can rotate freely; when the following situations occur, an alarm will be sounded to alert the accompanying personnel:

[0015] (1) When the patient tries to grasp the anti-grasp part with force, the patient's hand will grip the anti-grasp part tightly, generating pressure on the pressure sensor installed inside the anti-grasp part. At this time, the pressure sensor senses the pressure signal and converts the pressure signal into an electrical signal, which is transmitted to the signal converter. The signal converter judges whether the pressure is within a reasonable range based on the size of the received electrical signal. If it exceeds a certain threshold, it will send an alarm signal to the alarm module, causing the micro-buzzer to sound an alarm or the LED indicator to flash an alarm. (2) When the patient raises his hand to his face, which may cause unconscious scratching of the face, the infrared ranging module judges the distance between the patient's hand and the face based on the time it takes for the infrared light to travel from the transmitting end to the reflecting end, and converts the infrared signal into an electrical signal and transmits it to the signal converter. The signal converter judges whether the distance is within a reasonable range based on the size of the received electrical signal. If it exceeds a certain threshold, it will send an alarm signal to the alarm module, causing the micro-buzzer to sound an alarm or the LED indicator to flash an alarm.

[0016] Compared with the prior art, the present invention has at least the following advantages:

[0017] (1) Flexible limitation: The flexible mesh restricts dangerous grasping movements while retaining wrist mobility, thus avoiding the risk of pressure sores caused by traditional rigid restraints;

[0018] (2) Intelligent intervention: When a patient attempts to excessively grasp or raise their hands to a dangerous area, the alarm module immediately reminds the nursing staff to intervene, reducing the frequency of manual inspections;

[0019] (3) Comfort optimization: The silicone intervention component fits the curve of the hand, dissipating pressure and reducing discomfort caused by long-term wear. Flexible restrictions and active intervention replace rigid constraints, balancing safety and patient dignity, in line with the trend of precision care and humanized medical care.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to specific embodiments. It should be noted that the following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention. These all fall within the scope of protection of the present invention.

[0026] Example 1: A non-constrained intervention glove for reducing a patient's hand grip ability

[0027] The present invention provides a non-constrained intervention glove for reducing the gripping ability of a patient's hand, comprising: a glove body 1, a silicone intervention component 2 and a control unit 3.

[0028] The glove body 1 includes a flexible mesh sleeve 11 and a buckle 12 connected to the flexible mesh sleeve 11 .

[0029] The flexible mesh sleeve 11 is a double-layer elastic, breathable mesh sleeve, which provides excellent breathability and elasticity. This breathability ensures the patient's hand skin remains dry during prolonged glove wear, reducing skin problems caused by heat and humidity. Furthermore, its elasticity allows it to adapt to the size and shape of different patients' hands, enhancing wearing comfort. The flexible mesh sleeve 11 is equipped with a wrist-adjustable buckle 12 at the wrist. This buckle 12 utilizes a Velcro or snap-on design. Adjusting the position of the buckle 12 allows for quick and convenient adjustment to different wrist circumferences, ensuring the glove is securely fitted without being too tight and affecting blood circulation. The glove body 1 is made of woven nylon. This material is strong and wear-resistant, withstanding the pull and friction caused by daily activities, extending the glove's lifespan. Furthermore, its soft texture prevents scratches or pressure on the patient's skin. The glove body 1 covers the palm and fingers. Its unique mesh structure and sizing effectively limit the range of grip, making it difficult for the patient to exert force, thereby reducing the risk of self-injury. However, it allows the wrist to rotate freely and flex and extend slightly, ensuring the patient's hand's freedom of movement within a certain range and reducing the discomfort and psychological resistance caused by restricted limb movement.

[0030] The silicone intervention component 2 includes an anti-grip portion 21 and a ring 22, and the anti-grip portion 21 and the ring 22 are integrally formed. The anti-grip portion 21 is arranged on the outside of the palm side of the glove body 1, and the two ends of the ring 22 are connected to the anti-grip portion 21 to form a closed ring structure. The connection between the anti-grip portion 21 and the glove body 1 is non-detachable adhesive, ensuring that it will not fall off during the patient's activities. The shape of the anti-grip portion 21 is semicircular and finger-shaped (i.e., similar to the shape of a glove). When the anti-grip portion 21 is semicircular, the ring 22 is a palm ring; when the anti-grip portion 21 is finger-shaped, the ring 22 is a finger ring. The palm ring or finger ring can be put on the palm or finger respectively to strengthen the connection between the silicone intervention component 2 and the glove body 1.

[0031] The control unit 3 includes a pressure sensor 31 , an alarm module 32 , an infrared distance measurement module 33 , a signal converter 34 and a connecting line 35 . The control unit 3 is provided with a main power supply 36 .

[0032] The pressure sensor 31 is located inside the anti-grip portion 21 and senses the gripping pressure exerted on the anti-grip portion 21 by the patient's hand. It is a thin-film pressure sensor with ultra-thin and sensitive features. The signal converter 34 and alarm module 32 are both located on the back of the glove body 1. The infrared ranging module 33 includes a transmitter and a reflector. The transmitter / reflector is located on the outside of the glove body 1 near the first metacarpal joint of the palm, as well as on the pads of the index, middle, ring, and pinky fingers. The reflector / transmitter is located on the glove wearer's face in the form of a patch. This ensures that the infrared ranging module 33 accurately measures the distance between the patient's hand and face, avoiding false detection of the hand or other parts of the body and the resulting alarm. The signal converter 34 is connected to the pressure sensor 31, alarm module 32, and infrared ranging module 33 via a connecting cable 35. The connecting cable 35 passes through the silicone intervention component 2 or through the interlayer of the flexible mesh sleeve 11. The signal converter 34 is connected to the main power supply 36.

[0033] The pressure sensor 31 can accurately detect the force applied by the patient when grasping an object in real time. When the patient tries to grasp, the pressure sensor 31 converts the pressure signal it feels into an electrical signal and transmits it to the signal converter 34. The infrared ranging module 33 uses a high-precision infrared sensor that can monitor the distance between the hand and the face in real time, and converts the distance signal into an electrical signal and transmits it to the signal converter 34. The signal converter 34 transmits the received electrical signal to the alarm module 32. The signal converter 34 receives the signals transmitted by the pressure sensor 31 and the infrared ranging module 33, and performs real-time analysis and processing. An alarm is triggered when the following situations are detected: First, the grasping force exceeds the set threshold, which can be flexibly adjusted through the supporting control terminal according to the physical condition and care needs of different patients; second, the distance between the hand and the face (such as the nose) is less than the preset value. Similarly, the preset distance value can also be personalized on the control terminal.

[0034] The alarm module 32 includes a micro-buzzer and an LED indicator light. When the signal converter 34 issues an alarm command, the micro-buzzer emits a crisp sound and the LED indicator flashes, alerting medical staff or accompanying personnel to the patient's abnormal grasping behavior through both audio and visual signals. Through continuous monitoring by the pressure sensor 31 and infrared ranging module 33, it can effectively prevent injuries caused by patients unconsciously approaching their hands to the face (such as picking at their eyes, nose, mouth, etc.).

[0035] The main power supply 36 is a button battery. A switch is connected to the button battery, and the switch can perform the following functions: long press to turn on and off the machine; when the alarm module 32 sounds an alarm, double-click to turn off the alarm. In summary, the present device can reduce unnecessary physical restraints, reduce the incidence of patient anxiety, and reduce the number of daily inspections by nursing staff. Although traditional restraint gloves can prevent patients from grasping catheters or wounds, they have many serious disadvantages. Physiologically, rigid restraints can easily cause skin pressure sores, poor blood circulation, and limb swelling; psychologically, patients experience negative emotions such as anxiety and fear due to restricted activities, which reduces treatment compliance; in nursing work, frequent inspections and adjustments are required, which increases the workload of medical staff.

[0036] The above description of the embodiments is intended to facilitate understanding and use of the invention by those skilled in the art. It will be apparent that those skilled in the art can readily make various modifications to these embodiments and apply the general principles described herein to other embodiments without requiring inventive effort. Therefore, the present invention is not limited to the above-described embodiments. Improvements and modifications made by those skilled in the art based on the disclosure of the present invention, without departing from the scope of the present invention, should be within the scope of protection of the present invention.
