[0001] The present application relates to the field of restraints, more particularly to an ergonomic child blood extraction restraint. BACKGROUND

[0002] For the treatment of children and adults, wrist and arm treatment, physiotherapy, blood extraction and other operations, during the treatment process, patients often unconsciously move or move their limbs due to pain, and restraints are often used to restrain them.

[0003] In the medical field, child blood extraction is a common but challenging operation. During the child blood extraction operation, the existing restraint is mostly bound by a strap. However, during the restraint process, children are likely to move around due to nervousness, fear, and other emotions, such as pulling the blood tube and interfering with the normal operation of medical staff. This not only affects the smooth progress of blood extraction, but also may cause accidental injury to children, resulting in poor blood extraction protection effect. When moving around, the arm cannot be provided with stable support, causing children to feel uncomfortable. Moreover, the restraint cannot be self-adapted according to the thickness of the child's arm and cannot be adjusted, which makes the medical staff spend time in the early restraint process, reduces the restraint efficiency, and effectively restrains the patient, which interferes with the normal progress of treatment, reduces the treatment effect, and makes it difficult to guarantee the stability of treatment.

DETAILED DESCRIPTION

[0037] The present application will be described in detail below with reference to the drawings and specific embodiments. It should be noted that in order to make the embodiments more detailed, the following embodiments are the best, preferred embodiments, and other alternative ways can also be implemented by those skilled in the art for some known technologies; and the drawings are only used to describe the embodiments in more detail, and are not intended to specifically limit the present application.

[0038] It should be noted that in the specification, "one embodiment", "embodiment", "exemplary embodiment", "some embodiments" and the like indicate that the described embodiments can include specific features, structures or characteristics, but not necessarily every embodiment includes the specific features, structures or characteristics. In addition, when a specific feature, structure or characteristic is described in combination with an embodiment, it should be within the knowledge of those skilled in the art to realize this feature, structure or characteristic in combination with other embodiments (whether or not explicitly described).

[0039] Generally, the terminology can be understood at least in part from usage in context. For example, the term "one or more" as used herein, depending at least in part upon context, can be used to describe any feature, structure, or characteristic in a singular sense or can be used to describe combinations of features, structures or characteristics in a plural sense. Additionally, the term "based on" can be understood as not necessarily being confined to factors that are only explicit in a claim, but can instead be broadly understood as including factors that are both explicit and implicit to a claim. At least some of the features, structures, or characteristics can be combined in one or more aspects. Although the features, structures, or characteristics can be described in individual aspects, one or more aspects can include one or more of the features, structures, or characteristics from other aspects. The description can use perspective-based descriptions such as up / down. Such terms are merely used for descriptive purposes and not reflecting measurements of the devices as used by a user. The terms "coupled" and "connected" and variations thereof describe functional relationships, rather than necessarily physical relationships.

[0040] It is to be understood that the terms "on", "over", and "above", as used herein, are to be interpreted in the broadest context, such that "on" not only means "directly on" something, but also includes the meaning of being "on" something with intervening features or layers therebetween, and "over" or "above" not only means "over" or "above" something, but also can include the meaning of being "over" or "above" something with no intervening features or layers therebetween.

[0041] Furthermore, spatially relative terms, such as "beneath", "below", "lower", "above", "upper" and the like, can be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. The spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientations depicted in the figures. The devices can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein can likewise be interpreted accordingly.

[0042] As shown in Figures 1 to 10 The ergonomic child blood extraction restraint provided by the embodiment of the present application comprises a cross-shaped base 1, which is designed in the shape of a "cross" so as to provide stable support on a plane and ensure that the restraint will not easily shake or shift during use. The first arc-shaped frame 101 and the second arc-shaped frame 102 are rotatably connected to the cross-shaped base 1, respectively. A slide rod 2 is slidably connected to the intersection of the first arc-shaped frame 101 and the second arc-shaped frame 102. An arc-shaped stop plate 21 is fixed to the bottom surface of the slide rod 2. The rotation of the first arc-shaped frame 101 and the second arc-shaped frame 102 allows the placement table 3 to freely rotate within a certain range, so that the angle can be adjusted according to actual needs.

[0043] As shown in Figure 1 and Figure 2As shown, the top surface of the slide rod 2 is fixed with a placement table 3 for placing the limbs of children requiring medication, placing the arms requiring blood drawing, etc. The surface of the placement table 3 is smooth and has a certain softness to avoid causing compression or discomfort. The placement table 3 is provided with a placement groove 4 for facilitating the sliding of the slide rod 2, thereby realizing the flexible movement of the slide rod 2 between the two arc-shaped frames. The inner wall of the placement table 3 is provided with an inductive sheet sensor 5. It should be noted that the model of the inductive sheet sensor 5 is EZ-LS. When the child's arm is placed on the detection table, the inductive sheet sensor 5 can quickly respond, and the information such as the position of the limb and the arm circumference can be calculated through the internal matching measurement system, so that the subsequent adaptive adjustment can be realized, avoiding the problems of muscle tension, joint stiffness caused by too tight constraint of the patient's elbow and palm during the constraint process, or the problem of poor constraint effect caused by too loose constraint, and improving the comfort level.

[0044] The placement table 3 is fixed with a circular frame 6, which can limit the movement direction of the first pressing jaw 74 and ensure its stable vertical sliding. The placement table 3 is rotationally connected with a rotating rod 91, and the rotating rod 91 is fixedly sleeved with a fence plate 9. The overlapping part of the placement table 3 and the fence plate 9 is arranged in a semicircular shape. The rotation of the rotating rod 91 can drive the fence plate 9 to rotate. By controlling the rotation angle of the rotating rod 91, the position of the fence plate 9 can be adjusted, thereby realizing effective shielding and avoiding the child from moving around when medical staff corrects the limbs of the child, treats the wrist and arm, applies medicine for physiotherapy, or draws blood.

[0045] As shown in Figure 1 and Figure 2 , the placement table 3 is provided with a constraint assembly 7. The constraint assembly 7 includes a first pressing jaw 74 slidingly connected in the circular frame 6. The first pressing jaw 74 is fixedly connected with an L-shaped frame 75 at the end. The bottom of the L-shaped frame 75 is fixedly connected with a second pressing jaw 77. The second pressing jaw 77 is provided with a disinfection assembly 8 at the end.

[0046] As shown in Figure 3 , the first arc-shaped frame 101 and the second arc-shaped frame 102 are provided with annular grooves inside for facilitating the sliding of the slide rod 2. The top surface of the arc-shaped abutting plate 21 is in contact with the bottom surface of the second arc-shaped frame 102 for sliding, thereby ensuring the stability of the slide rod 2 during movement and also enabling the placement table 3 to better contact with the arm of the child and provide certain support and constraint.

[0047] As shown in Figure 2 , the bottom surface of the placement table 3 is fixedly connected with a base 71. The base 71 is fixedly connected with a motor 72. The motor 72 is electrically connected with the inductive sheet sensor 5. The output end of the motor 72 is fixedly connected with a lead screw 73. The lead screw 73 is rotationally installed on the placement table 3. The first pressing jaw 74 is threadedly connected with the lead screw 73. The placement table 3 is fixedly connected with a guide rod 76. The first pressing jaw 74 is slidingly sleeved with the guide rod 76.

[0048] Again Figure 2 As shown, the rotating rod 91 is fixedly connected with a gear 93, and the side wall of the first pressing claw 74 is fixedly connected with a toothed plate 92, and the gear 93 and the toothed plate 92 are in meshing relationship.

[0049] As Figure 1 And 2 As shown, in actual operation, whether it is limb correction, wrist and arm treatment, physiotherapy, blood drawing or other operations, the patient needs to place the arm to be treated in the placement slot 4 of the placement table 3. During the placement of the arm, the arm will come into contact with the inductive sheet sensor 5. The inductive sheet sensor 5 can quickly and accurately perceive the position, circumference and other detailed information of the child's or adult's limb, and rapidly integrate and process these information, convert them into data to generate an electrical signal, and transmit it to the motor 72. After receiving the signal, the motor 72 starts and drives the lead screw 73 to rotate. Since the first pressing claw 74 is tightly matched with the lead screw 73 through threads, when the lead screw 73 rotates, the first pressing claw 74 will move downward under the action of the threads, so that the first pressing claw 74 can tightly fit the rear end of the limb and firmly press and position it. This design enables the device to closely fit the contour of the patient's arm during limb correction, wrist and arm treatment, physiotherapy, blood drawing and other operations, greatly enhancing the stability of the constraint.

[0050] At the same time as the first pressing claw 74 moves downward, because the second pressing claw 77 is stably connected with the first pressing claw 74 through the L-shaped frame 75, and the initial position of the second pressing claw 77 is lower than that of the first pressing claw 74, when the first pressing claw 74 moves downward, the second pressing claw 77 will move downward synchronously and fit the rear end of the patient's arm. In this way, during various operations, the device can better adapt to the contour of the patient's arm and closely fit the rear end of the arm, further improving the stability of the constraint.

[0051] When the limb is properly constrained, if the child or adult patient moves the limb during limb correction, wrist and arm treatment, physiotherapy, blood drawing or other operations, the movement of the arm will be transmitted to the sliding rod 2 through the placement table 3. The sliding rod 2 will slide in the sliding track at the joint of the first arc-shaped frame 101 and the second arc-shaped frame 102, and at the same time, the first arc-shaped frame 101 and the second arc-shaped frame 102 will rotate according to the direction and intensity of the movement of the arm, so that the placement table 3 can adjust the position and angle in real time to adapt to the movement of the child's arm. Through the flexible adjustment of the placement table 3, the device can always closely fit the child's arm during use, providing continuous and stable support for the arm and effectively reducing the discomfort of the child caused by limb movement.

[0052] And in the process of moving down the first pressure clamp 74, the toothed plate 92 on the side wall thereof also moves down and contacts the gear 93, and since the toothed plate 92 and the gear 93 are in mesh with each other, the gear 93 rotates when subjected to the force transmitted by the toothed plate 92, thereby driving the rotating rod 91 connected thereto to rotate, and with the rotation of the rotating rod 91, the fence plate 9 sleeved on the outside of the rotating rod 91 also rotates and is in abutment with the arc-shaped part of the placement table 3, so that an occlusion area is formed, effectively avoiding that children pull the blood drawing tube or other auxiliary tools during the operation process of limb correction, wrist and arm treatment, physiotherapy and medicine application, blood drawing, etc. due to nervousness, fear and other emotions, thereby interfering with the normal operation of medical staff, improving the protection effect during the process of limb correction, wrist and arm treatment, physiotherapy and medicine application, blood drawing, etc., and providing strong guarantee for medical staff to complete the operation of limb correction, wrist and arm treatment, physiotherapy and medicine application, blood drawing, etc.

[0053] It should be noted that in the technical solution, although the device is mainly exemplified as being applied to the scene of blood drawing of children, in actual application, the device is widely applicable to many different operation directions, such as limb correction, wrist and arm treatment, physiotherapy and medicine application, etc. of children or adults. During the process of limb correction and wrist and arm treatment, patients often feel pain due to treatment, and such pain easily causes the patients to unconsciously move limbs, and the unconscious movement of the patients interferes with the normal progress of treatment and reduces the treatment effect. The constraint device can effectively constrain the patients and can minimize the limb shaking of the patients caused by pain, thereby improving the stability of treatment and providing strong guarantee for the smooth progress of treatment.

[0054] As shown in Figures 4 to 8 The disinfection assembly 8 includes a connecting column 81 fixedly connected to the surface of the second pressure clamp 77, a sliding column 83 is slidingly connected in the connecting column 81, the sliding column 83 is provided with a sliding track, and the sliding column 83 can freely slide in the connecting column 81. This sliding connection mode enables the sliding column 83 to adjust the position according to actual needs, so that the sliding column 83 can be displaced during the operation of the constraint device or to adapt to the arm length of different patients. A rotating shaft 85 is rotatably connected to the end of the sliding column 83, a storage bin 86 is fixedly connected to the end of the rotating shaft 85, a plurality of iodophor cotton swabs 814 are placed in the storage bin 86, a plurality of pins 82 are inserted into the connecting column 81, a plurality of insertion holes 84 are formed in the sliding column 83, and the pins 82 are inserted into the insertion holes 84. When it is necessary to adjust the position of the sliding column 83, the pins 82 can be manually pulled out, so that the sliding column 83 can slide in the connecting column 81; after being adjusted to a suitable position, the pins 82 are inserted into the corresponding insertion holes 84, so that the sliding column 83 and the connecting column 81 are fixed, and the position of the disinfection assembly 8 is relatively stable when the constraint device is used.

[0055] The storage bin 86 side wall is provided with an arc-shaped slot 861, and the storage bin 86 top is clamped with a cover plate 87, which is used to close the storage bin 86 and prevent the iodophor cotton swab 814 from being contaminated or accidentally falling. The storage bin 86 bottom side is fixedly connected with a first arc-shaped plate 88, and the other side is rotatably connected with a rotating rod 89. The rotating rod 89 is fixedly sleeved with a second arc-shaped plate 810, and the end of the rotating rod 89 is fixedly connected with a convex rod 811. The convex rod 811 end is fixedly connected with a connecting rod 812, and one end of the connecting rod 812 is fixedly connected with a spring 813. The other end of the spring 813 is fixedly connected with the inner wall of the arc-shaped slot 861. In the initial state, the iodophor cotton swab 814 is clamped between the first arc-shaped plate 88 and the second arc-shaped plate 810. When the iodophor cotton swab 814 is needed for disinfection, the second arc-shaped plate 810 is rotated by operating the rotating rod 89, the distance between the first arc-shaped plate 88 and the second arc-shaped plate 810 is changed, and the iodophor cotton swab 814 can be dropped for disinfection operation.

[0056] As shown in Figures 4 to 8 Before using the constraint device, the length of the patient's arm needs to be adjusted accordingly. During adjustment, the pin 82 is manually pulled out, so that the pin 82 is separated from the insertion hole 84 on the slide column 83 and the connecting column 81. Then, the storage bin 86 is pulled to drive the slide column 83 to slide outward in the connecting column 81. When the slide column 83 is in the appropriate position, the pin 82 is inserted into the connecting column 81 and penetrates through the corresponding insertion hole 84, so as to fix the slide column 83 and the connecting column 81.

[0057] Then, the disinfection cotton swabs are sequentially stacked in the storage bin. With the placement of the disinfection cotton swabs, the bottommost disinfection cotton swab will be clamped between the first arc-shaped plate 88 and the second arc-shaped plate 810 due to stress, and the bottom of the disinfection cotton swab will slide out to a distance that can just fit the skin.

[0058] When the preparation is ready, start the motor 72 when performing limb correction, wrist and arm treatment, physiotherapy, blood drawing and other treatment operations. The motor 72 drives the screw rod 73 to rotate. Since the first pressing jaw 74 is installed with the screw rod 73 through the thread, the screw rod 73 will drive the first pressing jaw 74 to move downward under the action of the thread. Since the first pressing jaw 74 is fixedly connected with the second pressing jaw 77 through the L-shaped frame 75, during the pressing process of the first pressing jaw 74 and the second pressing jaw 77, the connecting column 81 is fixedly connected with the second pressing jaw 77, the sliding column 83 is slidingly connected with the connecting column 81, and the storage bin 86 is rotationally connected with the sliding column 83 through the rotating shaft 85. Therefore, when the second pressing jaw 77 slides downward, the connecting column 81 will drive the storage bin 86 to move downward synchronously. Since the height of the storage bin 86 is higher than that of the second pressing jaw 77, the storage bin 86 will first contact the skin of the patient during the downward movement. Since a plurality of sterilized cotton swabs are placed in the storage bin 86, as the second pressing jaw 77 continuously moves downward, the sterilized cotton swabs at the bottom of the storage bin 86 will be deflected by force when they contact the skin, thereby causing the storage bin 86 to drive the rotating shaft 85 to rotate in the sliding column 83. As the storage bin 86 continuously rotates, the sterilized cotton swabs at the bottom thereof will slide along the surface of the skin of the affected limb, and the iodophor liquid in the sterilized cotton swabs will contact the surface of the skin, thereby producing a disinfecting effect.

[0059] After disinfection, since the convex rod 811, the rotating rod 89 and the connecting rod 812 are fixedly connected, after disinfection, the convex rod 811 is manually pressed, the convex rod 811 will drive the rotating rod 89 to rotate under force, and the connecting rod 812 at the end of the convex rod 811 will slide along the arc-shaped groove 861 and press the spring 813. As the rotating rod 89 rotates, the second arc-shaped plate 810 fixedly connected with the rotating rod 89 will also rotate. As the second arc-shaped plate 810 rotates, the resistance distance between the first arc-shaped plate 88 and the second arc-shaped plate 810 will change, so that the used sterilized cotton swabs will fall by nature. After the sterilized cotton swabs fall, the connecting rod 812 will immediately reset and slide under the action of the spring 813, and the convex rod 811 and the rotating rod 91 fixedly connected therewith will also rotate and reset synchronously, so that the second arc-shaped plate 810 quickly rotates to the initial position. During the resetting process of the second arc-shaped plate 810, since a plurality of sterilized cotton swabs are arranged in the storage bin 86, as the bottommost sterilized cotton swab falls, the remaining sterilized cotton swabs will move downward by nature under the action of inertia, so that the unused sterilized cotton swabs are clamped between the first arc-shaped plate 88 and the second arc-shaped plate 810 and slide to a distance capable of adhering to the skin. In this way, during the subsequent operation, the sterilized cotton swabs can be quickly replaced without the need for staff to take them additionally, thereby saving time and effort.

[0060] The auxiliary assembly 11 includes an electric push rod 111 fixed on the second pressing jaw 77, the output end of the electric push rod 111 is fixedly connected with a connecting plate 112, the surface of the connecting plate 112 is fixedly connected with a fixing rod 113, which is used for installing the medical tape 12 and providing a mounting position for the blocking plate 115. The fixing rod 113 is provided with an external thread 114, and the blocking plate 115 is threadedly connected with the external thread 114, which is used for limiting the position of the medical tape 12 and preventing the medical tape 12 from deviating or falling off during use. The connecting plate 112 is fixedly connected with a blade 116, and the connecting plate 112 is fixedly connected with two limiting rollers 117, which are used for guiding and limiting the medical tape 12, so that the medical tape 12 remains flat and stable during use, preventing the medical tape 12 from wrinkling or twisting. The fixing rod 113 is sleeved with the medical tape 12, and the medical tape 12 has adhesion and can be used to fix and constrain the body part of the patient. When medical staff perform limb correction, wrist and arm treatment, physiotherapy, blood drawing and other operations, they need to pull and paste the required bandage and cotton swab for hemostasis on the back of the hand in advance, and then paste the required bandage or medical tape 12 on the wound for auxiliary reinforcement after the operation. The auxiliary assembly 11 is added to the device, and the medical tape 12 is pulled to cover the part to be fixed during auxiliary fixation, so that the reinforcement of the wound is completed, and the steps of preparation and pressing of the medical staff are saved. The side wall of the second pressing jaw 77 is fixedly connected with a connecting frame 10, and the connecting frame 10 is provided with an infrared scanner 13.
