DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] like Figure 1-5 As shown, the utility model provides a technical solution:

[0030] The invention relates to an anti-grasp limb restraint device, comprising a glove body 1, the glove body 1 comprising a palm portion 11 and a finger portion 12, the palm portion 11 and the finger portion 12 being connected internally and used to place the patient's hand, the palm portion 11 being located on the outside of the patient's palm side and a gripping block 2 being provided for preventing the fingers from gripping in the direction of the palm, the gripping block 2 being bonded to the palm portion 11 to define its position; a side surface of the gripping block 2 that fits the palm is set as an arcuate surface, the interior of the gripping block 2 is set as a hollow surface, and a restraining unit is set in the gripping block 2, the restraining unit comprising a restraining belt 3, ... The strap 3 passes through the surface of the gripping block 2 and is connected to the finger portion 12, and is used to tighten the finger portion 12 so that it can be tightly attached to the surface of the gripping block 2. It is preferably connected to the side of the finger portion 12 away from the gripping block 2, so that the restraint stability is better; it also includes a wrist restraint assembly 4, including a lower restraint plate 41, which is arranged on the gripping block 2 and is located at the end of the palm portion 11 away from the finger portion 12, and is used to be close to the wrist and limit the position between the palm and the wrist. The lower restraint plate 41 can be fixed on the gripping block 2 or inserted into the gripping block 2 for easy storage.

[0031] In this embodiment, an opening is provided at one end of the finger portion 12 away from the palm portion 11, and a zipper 5 or Velcro is provided at the opening for opening the opening to expose the end of the finger. When measuring the patient's blood pressure and other physical indicators, it is only necessary to open the opening to measure without removing the device, thereby protecting the safety of the patient and medical staff and improving the practicality of the device.

[0032] In this embodiment, a loop 6 for passing the restraint belt 3 is provided on the back side of the finger portion 12 away from the gripping block 2. The restraint belt 3 is passed through the loop 6 to tighten the finger portion 12 so that the finger can be close to the surface of the gripping block 2 to avoid movement of the finger. At the same time, the loop 6 prevents the restraint belt 3 from falling off the finger portion 12, thereby improving the stability of the device.

[0033] In this embodiment, the side of the gripping block 2 close to the glove body 1 is set to an arc-shaped surface that fits the palm and fingertips of the human hand in a half-gripped state when the hand is relaxed, and the side of the gripping block 2 away from the glove body 1 is set to a plane that is on the same side as the inner side of the wrist when in use, so as to facilitate the connection of the lower constraint plate 41 and make the area that the lower constraint plate 41 can contact with the wrist as large as possible, thereby improving the practicality of the device.

[0034] In this embodiment, the finger portion 12 includes a thumb portion and four fingers. The surface of the gripping block 2 close to the thumb portion can be provided with a groove 1 for accommodating the thumb portion, and the upper surface of the gripping block 2 close to the four fingers is provided with a groove 2 for accommodating the four fingers. The two sides of the groove 1 on the gripping block 2 are penetrated by thumb holes for passing through the restraint belt 3, and the two sides of the groove 2 on the gripping block 2 are penetrated by four finger holes for passing through the restraint belt 3. The restraint belt 3 passes through the thumb hole away from the side of the four fingers and then passes through the thumb loop 6, then passes back to the thumb hole close to the four fingers, then passes out from the four finger hole close to the thumb, then passes through the four finger loops 6 in sequence and then passes back from the four finger hole away from the thumb, so that the finger portion 12 is connected to the gripping block 2 through the restraint belt 3.

[0035] The four fingers of the four-finger part in this embodiment are independently arranged. In another embodiment, they can also be arranged as an integral part, that is, the four fingers are in the same finger cuff space. In this case, only one band 6 is required, which is more convenient and quick for patients to wear.

[0036] In another embodiment, when each finger of the four-finger portion is independently provided, a hole for the restraint belt 3 to pass through can be provided on the gripping block 2 on both sides of each finger, so that each finger can be independently connected to the gripping block 2 through the restraint belt 3, thereby improving the effect of restraining a single finger and providing better safety and stability.

[0037] In another embodiment, a pulley can be provided between adjacent belt holes between the fingers on the inner side of the gripping block 2, and the pulley contacts the restraint belt 3 to reduce the friction between the restraint belt 3 and the gripping block 2 when the restraint belt 3 is tightened, thereby achieving a better restraint effect.

[0038] In this embodiment, the lower constraint plate 41 is arranged on the flat side of the gripping block 2, and the wrist restraint assembly 4 also includes a plurality of short constraint plates 42 and a winding rope 43. The plurality of short constraint plates 42 are connected to the end of the lower constraint plate 41 away from the gripping block 2 through the winding rope 43, and are used to be wound around the wrist to fix the position of the lower constraint plate 41 and provide support for the lower constraint plate 41. The short constraint plates 42 can be arranged on one side of the lower constraint plate 41 or on both sides of the lower constraint plate 41. By setting multiple short constraint plates 42 and winding ropes 43, adaptive adjustment can be performed according to the different thicknesses of the patient's wrist, which has a wider range of applications and improved practicality.

[0039] In some embodiments, the size of the glove body 1 can be set to different sizes according to the conventional glove sizes on the market, and corresponding sizes of grip blocks 2 are set for glove bodies 1 of different sizes to suit patients of different ages and different palm sizes, thereby improving the practicality of the device.

[0040] In this embodiment, the restraining unit also includes a tensioning assembly 7, a transmission assembly 8 and a positioning assembly 9. The tensioning assembly 7 includes a roller 71. The roller 71 is used to wind the restraining belt 3. The roller 71 is rotatably set on the inner wall of the gripping block 2 through a rotating seat. The roller 71 is connected to one end of the restraining belt 3 and enables the restraining belt to be wound on the roller 71. The other end of the restraining belt 3 passes through the gripping block 2 and passes through the belt ring 6 and is set on the inner wall of the gripping block 2 to limit the position of this end; a connecting disk 72 and a chuck 73 are coaxially arranged at both ends of the roller 71. The connecting disk 72 is used to connect to the transmission assembly 8, and the chuck 73 is used to connect to the positioning assembly 9. The restraining belt 3 is tightened by the roller 71, which is more efficient.

[0041] In this embodiment, the transmission assembly 8 includes a power piece 81. The power piece 81 is a small telescopic motor with an output end that can be extended and retracted. The power piece 81 is arranged on the inner wall of the gripping block 2. The output end of the power piece 81 is coaxially provided with a friction disc 82. The friction disc 82 is in coaxial contact with the connecting disc 72. The surfaces of the friction disc 82 and the connecting disc 72 that contact each other are both set to rough surfaces, which are used to drive the connecting disc 72 to rotate by friction, so as to drive the roller 71 to rotate. In the process of driving the connecting disc 72 to rotate, since the degree of tension of the roller 71 on the restraint belt 3 is limited, when the tension between the roller 71 and the restraint belt 3 is greater than the friction force between the friction disc 82 and the connecting disc 72, the friction disc 82 slips, and the roller 71 no longer pulls the restraint belt 3. By changing the pressing force of the friction disc 82 on the connecting disc 72 by the telescopic motor, the final tension of the roller 71 on the restraint belt 3 can be changed, that is, the restraint force of the restraint belt 3 on the finger part 12 can be changed to adapt to patients with different restraint requirements, thereby improving the practicality of the device.

[0042] In this embodiment, a plurality of unidirectional latching teeth 74 are provided around the circumferential direction of the chuck 73, and the latching teeth 74 and the chuck 73 together form a ratchet structure; the locking assembly 9 includes a support shaft 91, and the support shaft 91 is slidably provided inside the gripping block 2, and a latching block 92 is provided on the support shaft 91, and the latching block 92 is used to engage with the latching teeth 74, and a spring 93 is provided at the end of the support shaft 91 opposite to the tip of the latching teeth 74, and the end of the support shaft 91 away from the spring 93 passes through the gripping block 2, and the end of the support shaft 91 located outside the gripping block 2 serves as a release button for releasing the restraining state of the restraint belt 3, and the position of the release button should avoid possible contact with the patient's thumb, and a limit block 94 is provided at the position of the support shaft 91 inside the gripping block 2, and the limit block 94 contacts the inner wall of the gripping block 2 to avoid the patient's thumb from touching the latching teeth 74. When the chuck 73 is in operation, the support shaft 91 moves toward the outside of the gripping block 2. When in use, the chuck 73 rotates to drive the latch teeth 74 to contact the latch block 92 in turn. At this time, the contact surface of the latch teeth 74 and the latch block 92 is an inclined surface, and the latch block 92 will not engage with the latch teeth 74. At the same time, the latch block 92 can move back and forth slightly through the spring 93, which is convenient for the chuck 73 to drive the latch teeth 74 to rotate. After the strap 3 is restrained in place, the chuck 73 will have a tendency to rotate in the opposite direction, but at this time the latch teeth 74 are engaged with the latch block 92, and the limit block 94 limits the outward movement of the support shaft 91, making the device more stable. When the strap 3 needs to be released, the release button is pressed. At this time, the latch teeth 74 are disconnected from the latch block 92, and the chuck 73 can rotate in the opposite direction to release the strap 3 in the reverse direction, allowing the patient to take off the device, thereby improving the safety of the device.

[0043] In another embodiment, a button protection cover may be provided on the release button to prevent the patient from accidentally touching the release button due to erratic movement, thereby improving safety.

[0044] In this embodiment, a protective plate 10 is also included. The protective plate 10 is arranged on the side of the grip block 2 away from the glove body 1 to protect the grip block 2. Preferably, the protective plate 10 is made of a rubber plate or a flexible plastic plate with a certain elasticity to prevent the patient from bringing the grip block 2 into contact with sharp or hard objects, which may damage the grip block 2, thereby improving the economy of the device.

[0045] In some embodiments, the power member 81 is powered by a battery and further includes a control component for controlling the movement of the power member 81 to better achieve the restraining action and improve the efficiency of the device.

[0046] In some embodiments, an observation window or ventilation hole can be opened on the back of the palm portion 11 away from the palm of the patient to facilitate air circulation between the patient's hand and the outside, reduce sweating of the patient's hand, provide a comfortable hand environment, help ease the patient's mentality, and improve the practicality of the device.

[0047] Working principle: First, the medical staff opens the opening of the palm part 11 of the glove body 1 so that the patient's hand can enter the inside of the glove and place different fingers in the corresponding finger parts 12; then the opening of the palm part 11 is fitted to the base of the patient's palm and closed, and a magic tape can be used to wrap it to prevent the patient's hand from falling out of the opening of the palm part 11; then the lower constraint plate 41 is fitted to the bottom of the patient's palm, wrist and front end of the forearm, and then the short constraint plate 42 is wrapped around and tied to the patient's forearm through the winding rope 43 to provide a support point for the lower constraint plate 41; then the power part 81 is started, and the restraint belt 3 is wrapped through the transmission roller 71, so that the patient's fingers can fit tightly against the surface of the gripping block 2 to avoid possible danger caused by free movement of the fingers; when the device needs to be taken off, just press the release button to release the restraint belt 3, which improves the practicality of the device.
