Description

Technical Field

[0001] This invention relates to the field of medical assistive devices, and more specifically to a locally adjustable hand restraint. Background Technology

[0002] Some mentally ill patients may self-harm, scratch or grab sharp objects such as syringes or scissors from medical staff during an episode, which could lead to accidental injury to themselves or medical staff. Therefore, for patients with more severe symptoms, it is necessary to wrap their hands to prevent them from moving their palms freely and suddenly grabbing sharp objects, which could lead to self-harm or injury to others.

[0003] Currently, although there is a protective glove for mental patients disclosed in patent number CN209695513U, which includes a left glove, a right glove and a connecting strap, the wrist of the left and right gloves is respectively wrapped with a tightening strap, and the connecting strap is respectively connected to the tightening strap in the wrist of the left and right gloves. The middle of the connecting strap is provided with an elastic band, and a first restraint strap is provided between two adjacent finger sleeves of the left and right gloves to control the separation distance between the corresponding two fingers. The front end of each finger sleeve of the left and right gloves is provided with a flexible fingertip sleeve, and the gloves are also provided with an infusion port and a shielding part, so that intravenous infusion treatment can be performed while the mental patient is wearing the protective gloves.

[0004] However, in actual use, due to different body types, blood vessel thickness, hand size and other specific circumstances, even when administering intravenous fluids on the back of the hand, there are differences in the infusion position or the infusion position and the shielding part cannot be completely aligned. If the shielding part is designed too small, it will not be able to be aligned with the appropriate infusion position. If the shielding part is designed too large, the fingers will easily protrude from the shielding part when the glove is put on the patient's hand.

[0005] Furthermore, the gloves are designed with separate fingers, which may cause patients to refuse to wear them if they are emotionally agitated. Therefore, they are difficult to put on. Even if they are put on, the separate-finger design cannot completely prevent patients from grabbing dangerous items. Summary of the Invention

[0006] The present invention aims to provide a locally adjustable hand restraint to solve the problems of high difficulty in wearing and inability to fully expose the infusion site.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a locally adjustable hand restraint device, comprising a sleeve, a flexible unit, and a hollow restraint unit. A positioning ring is fixed to one side of the sleeve. The flexible unit comprises an upper glove portion and a lower glove portion, which are respectively located on the upper and lower sides of the positioning ring. Both the upper and lower glove portions are detachably connected to the positioning ring. The hollow restraint unit comprises an upper flexible mesh and a lower flexible mesh, which are opposite to the palm portion of the positioning ring. The upper and lower flexible meshes are respectively located on the upper and lower sides of the positioning ring, and both ends of the upper and lower flexible meshes extend from the sides of the upper and lower glove portions to the outside of the positioning ring.

[0008] The beneficial effects of this plan are: The restraint device in this solution features a modular design, with the sleeve, upper glove, and lower glove components installed individually, reducing the difficulty of wearing it. Existing technologies typically do not consider how to clean the patient's hands during prolonged wear. However, in practice, it has been found that some uncooperative patients require their hands to be wrapped for 1-2 days or even longer. Furthermore, some patients' hands tend to sweat more easily when emotionally agitated. Without cleaning for such a long time, unpleasant odors often develop when the restraint is loosened, which is detrimental to the patient's health.

[0009] When using the restraint device in this solution, the upper flexible net is bent downwards and fixed to bind the patient's palm to the lower glove section, while still maintaining restraint on the patient's hand. Similarly, when it is necessary to clean the back of the patient's hand or palm, the upper or lower glove section can be removed separately, in which case the flexible net will not obstruct the skin.

[0010] Meanwhile, during injection, the patient's hand is initially fixed by pressing the upper flexible mesh against the lower glove, keeping the hand in an open position. The flexible mesh has a mesh structure, which does not hinder medical personnel from confirming the injection site. Once the injection site is determined, the upper flexible mesh opposite the site is cut with scissors to create a larger window, allowing the patient to receive the injection without completely relaxing the arm.

[0011] Furthermore, both ends of the upper and lower flexible nets are fixed with straps.

[0012] The beneficial effect of this solution is that the upper and lower flexible nets can be quickly fixed by means of ties.

[0013] Furthermore, the top and bottom of the positioning ring are provided with U-shaped grooves, the openings of which face the upper glove part and the lower glove part respectively, and the U-shaped grooves extend laterally through the positioning ring.

[0014] The beneficial effects of this solution are as follows: the U-shaped groove design allows the upper and lower flexible meshes to be pulled to unfold when it is necessary to limit the patient's palm, thereby improving the pressure and limiting effect on the patient's palm.

[0015] Furthermore, the thickness of the positioning ring is 1~2.5cm.

[0016] The beneficial effects of this solution are as follows: the positioning ring in this solution has a relatively small thickness, which allows the upper flexible mesh to better press the palm onto the lower glove part, and similarly, the lower flexible mesh can better press the palm onto the upper glove part.

[0017] Furthermore, a lower support sleeve is provided, the shape of which is the same as that of the positioning ring, and the lower support sleeve and the positioning ring are detachably connected. The lower support sleeve is provided with an upward-facing receiving groove.

[0018] The beneficial effects of this solution are as follows: The lower support sleeve in this solution is rigid. When used in conjunction with the upper flexible mesh during infusion, it will not deform under pressure, thus better keeping the patient's palm in an open state and improving the limiting effect.

[0019] Furthermore, the sidewalls or bottom of the lower support sleeve are provided with protrusions.

[0020] Furthermore, a limiting groove is provided in the middle of the protrusion.

[0021] The beneficial effect of this solution is that the straps can be quickly tightened by wrapping them around the protrusion in a U-shape, thereby quickly unfolding the upper and lower flexible nets.

[0022] Furthermore, the lower support sleeve is covered with a flexible layer.

[0023] The beneficial effect of this solution is that the flexible layer acts as a buffer, thereby improving comfort.

[0024] Furthermore, the sleeve has a C-shaped cross-section along the vertical direction and can be bent and deformed; both ends of the sleeve are fixed with locking straps.

[0025] The beneficial effects of this solution are as follows: the sleeve has an opening along the axial direction, so the patient's hand does not need to be passed through the cylindrical sleeve opening when wearing it. This can prevent the patient from having their fingers completely spread out and unable to pass through the sleeve opening due to non-cooperation, thus avoiding the situation where the sleeve cannot be worn. Attached Figure Description

[0026] Figure 1 This is an exploded view of an embodiment of the present invention. Detailed Implementation

[0027] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: sleeve 1, locking strap 11, mounting base 12, positioning ring 2, U-shaped groove 21, lower support sleeve 3, receiving groove 31, upper glove part 4, lower flexible net 5, tie 51, and upper flexible net 6.

[0028] Example The implementation examples are basically as follows Figure 1 As shown, a locally adjustable hand restraint device includes a sleeve 1, a flexible unit, and a hollow restraint unit. The sleeve 1 is C-shaped and made of a material that can bend and deform. An opening extending along the length direction is formed on the sleeve 1. Several C-shaped fixing blocks are provided at both ends of the opening along the length direction of the sleeve 1, and the fixing blocks are bent away from the opening. A locking strap 11 is provided. The two ends of the locking strap 11 are similar to shoelaces and are zigzag-shaped, passing around the fixing blocks on both sides of the opening. Tightening the two ends of the locking strap 11 can tighten the opening of the sleeve 1 and fix the sleeve 1 to the patient's arm.

[0029] A C-shaped mounting base 12 is glued to the side of the sleeve 1 near the wrist, and the opening direction of the mounting base 12 is the same as that of the sleeve 1. A positioning ring 2 is detachably connected to the right side of the mounting base 12. The positioning ring 2 is made of rigid material, is horizontally set, and its two left ends are inserted into the mounting base 12 and engaged with it. In this embodiment, the thickness of the positioning ring 2 is 1.5cm.

[0030] The flexible unit includes an upper glove portion 4 and a lower glove portion, which are located above and below the positioning ring 2, respectively. Both the upper glove portion 4 and the lower glove portion are made of multiple layers of cotton or gauze to form a soft, glove-like structure with a certain thickness. Specifically, in this embodiment, the upper glove portion 4, the lower glove portion, and the positioning ring 2 have the same shape and each includes a first space for accommodating the thumb and a second space for accommodating the palm and remaining fingers. In practical implementation, positioning ring 2, upper glove portion 4, and lower glove portion of various sizes can also be designed to accommodate patients with different hand sizes.

[0031] Both the upper glove part 4 and the lower glove part are detachably connected to the positioning ring 2 by fasteners or Velcro. The top and bottom of the positioning ring 2 are provided with U-shaped grooves 21. The U-shaped grooves 21 are located at the palm part of the positioning ring 2 and extend laterally through the front and rear side walls of the positioning ring 2 in the second space. In this embodiment, the U-shaped grooves 21 are located between adjacent fasteners or Velcro.

[0032] The hollow constraint unit includes an upper flexible mesh 6 and a lower flexible mesh 5, and both the upper flexible mesh 6 and the lower flexible mesh 5 are made of mesh that can be bent and deformed. Specifically, in this embodiment, the upper flexible mesh 6 and the lower flexible mesh 5 are both made of nylon material. The two ends of the upper flexible mesh 6 and the lower flexible mesh 5 extend from the U-shaped grooves 21 on the upper and lower sides to the outside, and both ends of the upper flexible mesh 6 and the lower flexible mesh 5 are fixed with straps 51.

[0033] A lower support sleeve 3 is also provided. The lower support sleeve 3 is made of rigid plastic and has the same shape and size as the lower glove. It can also be detachably connected to the positioning ring 2 via buckles or Velcro. The lower support sleeve 3 has an upward-facing receiving groove 31. Both the receiving groove 31 and the bottom of the lower support sleeve 3 are flat to keep the patient's palm in an open position. The outer side of the lower support sleeve 3 is covered with a face mask or gauze to form a flexible layer to cushion the rigid lower support sleeve 3. The front and rear sidewalls of the lower support sleeve 3 are integrally formed with protrusions, which are located at the lower part of the sidewalls of the support sleeve and penetrate through the flexible layer and extend to the outer side of the flexible layer. The bottom of the protrusion has a limiting groove to limit the tie 51. In practice, first open sleeve 1, then slip the C-shaped sleeve 1 onto the patient's arm. Next, secure the sleeve 1 by wrapping the locking strap 11 around the C-shaped fixing block. Then, attach the upper glove 4 and lower glove 4 above and below the positioning ring 2, completing the hand wrapping. This protects the patient's fingers, preventing them from scratching medical staff or grabbing dangerous items such as syringes or scissors. If the patient is emotionally agitated and poses a risk of harm, the strap can be directly tied to the outside of sleeve 1 and secured to the bed railing. Compared to the strap directly touching the patient's arm, this provides a larger contact area between sleeve 1 and the arm, offering greater comfort and preventing discomfort that could further worsen the patient's mood.

[0034] When prolonged use necessitates cleaning the patient's hands, before putting on the upper glove 4 and lower glove 5, first cover the back of the patient's hand and the palm with the upper flexible mesh 6 and lower flexible mesh 5 respectively. After putting on the upper glove 4 and lower glove 5, bend both ends of the upper flexible mesh 6 and lower flexible mesh 5 upwards and secure them with the straps 51. When cleaning the patient's hands, bend both ends of the lower flexible mesh 5 upwards and secure it above the upper glove 4. This restrains the patient's palm upwards. At this point, removing the lower glove 4 exposes the patient's palm for cleaning. When cleaning the back of the hand or administering intravenous fluids, bend the upper flexible mesh 6 downwards and secure it below the lower glove 4. Then, removing the upper glove 4 exposes the back of the hand.

[0035] When administering intravenous injection, if the patient's cooperation is poor, the lower glove can be replaced with the lower support sleeve 3 while the patient's palm is restrained by the lower flexible net 5. Then, medical tape can be pressed onto the non-infusion position and fixed to the rigid lower support sleeve 3 to further fix the patient's hand in an open palm position on the lower support sleeve 3. Then, the upper flexible net 6 at the infusion position can be cut open to fully expose the infusion position, making the operation easier.
