Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a hand restraint device. Background Technology

[0002] For some patients who randomly scratch with their hands, there are potential risks to both medical staff and the patients themselves, so it is necessary to restrain their hands.

[0003] The current method of restraint involves binding the hands to a board to ensure complete hand restraint. However, complete hand restraint is extremely unfriendly and uncomfortable for patients, and the inability to move increases their anxiety and pain. Utility Model Content

[0004] This utility model discloses a hand restraint device to improve the above-mentioned problems.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is:

[0006] To achieve the above objectives, this utility model discloses a hand restraint device, comprising:

[0007] The lower housing has a lower half-groove.

[0008] An upper housing is attached to a lower housing to form a receiving cavity. The upper housing and the lower housing are rotatably connected. An upper half-groove is provided on the upper housing. The upper half-groove and the lower half-groove cooperate to form a limiting hole. The upper housing is rotated to open or close the limiting hole.

[0009] A play structure is installed within the receiving cavity;

[0010] A first snap-fit ​​structure is installed on the lower housing;

[0011] The second snap-fit ​​structure is installed on the upper housing and engages with the first snap-fit ​​structure.

[0012] At least one of the upper shell and the lower shell is made of a rigid material.

[0013] The hand restraint device disclosed in this utility model can restrict the patient's hand within the receiving cavity, ensuring the patient's range of motion while restricting the hand. This prevents the patient from grabbing randomly while allowing sufficient movement to alleviate discomfort. Furthermore, even when the patient's hand is restricted within the receiving cavity, there is still room for movement, and the patient's hand can still move on the play structure. The hand is not completely restricted, which further reduces patient discomfort.

[0014] Optionally, both the upper housing and the lower housing are made of rigid materials.

[0015] This ensures that the hand restraints have sufficient support, allowing the patient's hand to move freely within the cavity.

[0016] Optionally, a padding layer is provided on both the inner and outer walls of the lower housing, and a padding layer is provided on both the inner and outer walls of the upper housing.

[0017] On the one hand, it can prevent the patient's hand from being injured inside the cavity; on the other hand, when the patient's arm swings, it can also prevent the hand restraint from injuring the patient or others.

[0018] Optionally: The play structure includes a column and a rotating block, wherein the rotating block is rotatably connected to the column.

[0019] Patients can interact with the rotating blocks, ensuring their hands have a certain amount of movement and preventing other injuries caused by boredom.

[0020] Optionally: the upper housing is provided with a positioning groove, the bottom of the column is fixedly connected to the lower housing, and the top of the column is engaged with the positioning groove.

[0021] This facilitates the opening and closing of the upper and lower shells, and after the upper and lower shells are fastened together, the positioning groove can be used to position the column, thereby making the column more stable.

[0022] Optionally, an observation window is provided on the upper housing or the lower housing, and the observation window is made of transparent material.

[0023] Setting up an observation window allows medical staff to monitor the patient's hand condition at any time, enabling them to take quick action and reduce the possibility of serious injury to the patient's hand while it is restrained.

[0024] Optionally: a rotating shaft is provided between the upper housing and the lower housing, the lower half-groove is located on the side wall of the lower housing opposite to the rotating shaft, and the first snap-fit ​​structure and the lower half-groove are respectively located on two adjacent side walls of the lower housing.

[0025] This makes assembly more convenient, and the fact that the first and second snap-fit ​​structures are far from the limiting hole allows them to be kept away from the patient's arm, thus preventing the first and second snap-fit ​​structures from scratching the patient's arm.

[0026] Optionally: the first snap-fit ​​structure includes a first snap-fit ​​seat, the first snap-fit ​​seat is installed on the lower housing, and the first snap-fit ​​seat is provided with a limiting hole, the limiting hole having a rectangular cross-section;

[0027] The second snap-fit ​​structure includes a second snap-fit ​​seat, a threaded rod, and a limiting block. The second snap-fit ​​seat is installed on the upper housing. The threaded rod is threadedly engaged with the second snap-fit ​​seat. The limiting block is connected to the threaded rod, and the shape of the limiting block is adapted to the shape of the limiting hole. The threaded rod is rotated to align or offset the corner of the limiting block with the corner of the limiting hole.

[0028] After the upper and lower housings are fastened together, the limiting block passes right through the limiting hole, at which point the limiting block can be rotated. On one hand, the orientation of the limiting block is offset from the orientation of the limiting hole, preventing the limiting block from directly passing through the limiting hole, thus achieving the connection and fixation of the upper and lower housings. On the other hand, the limiting block drives the threaded rod to rotate, allowing the limiting block to move towards the first locking seat. After the limiting block and the first locking seat are pressed together, it can prevent the upper housing from shaking relative to the lower housing, thereby ensuring that the limiting hole remains in the fastened state, and thus preventing the patient from being pinched due to the opening and closing movement of the upper and lower housings.

[0029] Optionally: The second snap-fit ​​seat is provided with a threaded hole, the threaded hole penetrates the second snap-fit ​​seat along the height direction of the second snap-fit ​​seat, and the threaded rod is threadedly engaged with the first end of the threaded hole;

[0030] The second snap-fit ​​structure also includes a control bolt, which and the threaded hole are threadedly engaged with the second end opposite to the first end.

[0031] By adjusting the position of the control bolt, it can be ensured that when the threaded rod abuts against the control bolt, the position of the corner of the limit block corresponds exactly to the position of the corner of the limit hole, so that the limit block can pass directly through the limit hole.

[0032] Optionally, the second snap-fit ​​structure further includes a first stop and a second stop. The first stop is mounted on the threaded rod, and the second stop is mounted on the second snap-fit ​​seat. The second stop is located on the moving path of the first stop. When the first stop abuts against the second stop, the corner of the limiting block is aligned with the corner of the limiting hole.

[0033] When disassembly is required, rotate the limiting block in the opposite direction so that the first stop block abuts against the second stop block. At this time, the position of the corner of the limiting block corresponds exactly to the position of the corner of the limiting hole, which can directly divide the force between the second locking structure and the first locking structure to achieve quick disassembly.

[0034] Compared with the prior art, the beneficial effects achieved by this utility model are:

Detailed Implementation

[0048] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0049] Example:

[0050] See Figures 1 to 9 This utility model discloses a hand restraint device, comprising a lower housing 100, an upper housing 200, a play structure 700, a first snap-fit ​​structure 300, and a second snap-fit ​​structure 400. The lower housing 100 has a lower half-groove 110, and the upper housing 200 covers the lower housing 100 to form a receiving cavity 500. The upper housing 200 and the lower housing 100 are rotatably connected, and the upper housing 200 has an upper half-groove 210. The upper half-groove 210 and the lower half-groove 110 cooperate to form a limiting hole 600. Rotating the upper housing 200 opens or closes the limiting hole 600, and the play structure 700 is installed within the receiving cavity 500. The first snap-fit ​​structure 300 is installed on the lower housing 100, and the second snap-fit ​​structure 400 is installed on the upper housing 200, with the second snap-fit ​​structure 400 engaging with the first snap-fit ​​structure 300. At least one of the upper housing 200 and the lower housing 100 is made of a rigid material.

[0051] The hand restraint device disclosed in this utility model can restrict the patient's hand within the receiving cavity 500. While maximizing the patient's range of motion, it restricts the patient's hand, preventing the patient from grabbing randomly and ensuring that the patient can perform sufficient activities to reduce discomfort. In addition, even when the patient's hand is restricted within the receiving cavity 500, there is still room for movement, and the patient's hand can still move on the play structure 700. The patient's hand is not completely restricted, which can further reduce the patient's discomfort.

[0052] In one embodiment, both the upper housing 200 and the lower housing 100 are made of rigid material. This ensures that the hand restraint has sufficient support to allow the patient's hand room to move within the receiving cavity 500.

[0053] In one embodiment, a cushioning layer is provided on both the inner and outer walls of the lower housing 100, and a cushioning layer is provided on both the inner and outer walls of the upper housing 200.

[0054] On the one hand, it can prevent the patient's hand from being injured within the 500-inch cavity. On the other hand, when the patient's arm swings, it can also prevent the hand restraint from injuring the patient or others.

[0055] In one embodiment, the play structure 700 includes a column 710 and a rotating block 720, the rotating block 720 being rotatably connected to the column 710. The patient can interact with the rotating block 720, thereby ensuring that the patient's hand has a certain amount of activity and preventing other injuries caused by boredom.

[0056] In one embodiment, the two ends of the column 710 are connected to the lower housing 100 and the upper housing 200, respectively. Reducing the protruding portion of the play structure 700 can reduce the probability of the play structure 700 colliding with the patient's hand, and can also prevent the protruding portion from scratching the patient's hand. In addition, the column 710 can also provide a certain support for the upper housing 200 and the lower housing 100, ensuring that the receiving cavity 500 has sufficient space.

[0057] In one embodiment, the upper housing 200 is provided with a positioning groove 220, the bottom of the column 710 is fixedly connected to the lower housing 100, and the top of the column 710 is engaged with the positioning groove 220.

[0058] This facilitates the opening and closing of the upper housing 200 and the lower housing 100. After the upper housing 200 and the lower housing 100 are fastened together, the positioning groove 220 can be used to position the column 710, thereby making the column 710 more stable.

[0059] In one embodiment, an observation window is provided on either the upper housing 200 or the lower housing 100, and the observation window is made of a transparent material. Of course, it is also possible to provide observation windows on both the upper housing 200 and the lower housing 100; furthermore, it is also possible for both the upper housing 200 and the lower housing 100 to be made entirely of a transparent material. Providing an observation window allows medical personnel to easily observe the patient's hand condition at any time, thereby facilitating rapid intervention and reducing the possibility of serious injury to the patient's hand within the restraint device.

[0060] In one embodiment, a rotating shaft is provided between the upper housing 200 and the lower housing 100, the lower half-groove 110 is located on the side wall of the lower housing 100 opposite to the rotating shaft, and the first snap-fit ​​structure 300 and the lower half-groove 110 are respectively located on two adjacent side walls of the lower housing 100.

[0061] This makes assembly more convenient, and the first snap-fit ​​structure 300 and the second snap-fit ​​structure 400 are far away from the limiting hole 600, which can keep the first snap-fit ​​structure 300 and the second snap-fit ​​structure 400 away from the patient's arm, thereby avoiding the first snap-fit ​​structure 300 and the second snap-fit ​​structure 400 from scratching the patient's arm.

[0062] In one embodiment, the first snap-fit ​​structure 300 includes a first snap-fit ​​seat 310, which is mounted on the lower housing 100. The first snap-fit ​​seat 310 is provided with a limiting hole 320, which has a rectangular cross-section.

[0063] The second snap-fit ​​structure 400 includes a second snap-fit ​​seat 410, a threaded rod 420, and a limiting block 430. The second snap-fit ​​seat 410 is installed on the upper housing 200. The threaded rod 420 is threadedly engaged with the second snap-fit ​​seat 410. The limiting block 430 is connected to the threaded rod 420, and the shape of the limiting block 430 is adapted to the shape of the limiting hole 320. The threaded rod 420 is rotated so that the corner of the limiting block 430 is aligned with or offset from the corner of the limiting hole 320.

[0064] After the upper housing 200 and the lower housing 100 are fastened together, the limiting block 430 passes through the limiting block 430, and the limiting block 430 can be rotated at this time. On the one hand, the orientation of the limiting block 430 is offset from the orientation of the limiting hole 320, so the limiting block 430 cannot pass directly through the limiting hole 320, thus achieving the connection and fixation between the upper housing 200 and the lower housing 100; on the other hand, the limiting block 430 drives the threaded rod 420 to rotate, which allows the limiting block 430 to move towards the first locking seat 310. After the limiting block 430 and the first locking seat 310 are pressed together, the upper housing 200 can be prevented from shaking relative to the lower housing 100, thereby ensuring that the limiting hole 600 remains in the fastened state, and thus preventing the patient from being pinched due to the opening and closing of the upper housing 200 and the lower housing 100.

[0065] In one embodiment, the second snap-fit ​​seat 410 is provided with a threaded hole 411, which penetrates the second snap-fit ​​seat 410 along the height direction of the second snap-fit ​​seat 410, and the threaded rod 420 is threadedly engaged with the first end of the threaded hole 411.

[0066] The second snap-fit ​​structure 400 also includes a control bolt 440, and the control bolt 440 and the threaded hole 411 are threadedly engaged with the second end opposite to the first end.

[0067] By adjusting the position of the control bolt 440, it can be ensured that when the threaded rod 420 abuts against the control bolt 440, the position of the corner of the limit block 430 corresponds exactly to the position of the corner of the limit hole 320, so that the limit block 430 can pass directly through the limit hole 320.

[0068] In one embodiment, the second snap-fit ​​structure 400 further includes a first stop 450 and a second stop 460. The first stop 450 is mounted on the threaded rod 420, and the second stop 460 is mounted on the second snap-fit ​​seat 410. The second stop 460 is located on the movement path of the first stop 450. When the first stop 450 abuts against the second stop 460, the corner of the limiting block 430 is aligned with the corner of the limiting hole 320.

[0069] When disassembly is required, the limiting block 430 is rotated in the opposite direction so that the first stop 450 abuts against the second stop 460. At this time, the position of the corner of the limiting block 430 corresponds exactly to the position of the corner of the limiting hole 320. The second snap-fit ​​structure 400 and the first snap-fit ​​structure 300 can be directly connected to achieve quick disassembly.

[0070] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
