Description

Technical Field

[0001] The utility model relates to the technical field of infant indwelling needles, in particular to a limiting wristband for protecting infant indwelling needles. Background Art

[0002] A tendon and vein indwelling needle is a medical needle consisting of a stainless steel needle core, a soft outer sleeve and a plastic needle seat. When in use, the outer sleeve and the stainless steel needle core are inserted into the human blood vessel together. After insertion, the stainless steel needle core is pulled out, leaving the outer sleeve in the blood vessel for convenient infusion. Traditional infusion indwelling needles are generally fixed to the skin surface with medical tape or transparent dressings. This fixing method is prone to loose adhesion, causing the plastic needle seat to detach and move from the skin, resulting in the retention needle being loosely attached. In addition, when using an indwelling needle in young children, due to their activeness and the ease with which the indwelling needle may fall off, it is very inconvenient to insert the needle again once it falls off. Utility Model Content

[0003] The purpose of the utility model is to provide a limiting bracelet for protecting an indwelling needle for children, so as to solve the problem in the above background technology that the indwelling needle is very easy to be dislocated from the skin when used on children.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a limiting bracelet for protecting an indwelling needle in children, comprising a bracelet body, a first strap being provided on the side surface of one end of the bracelet body, and the first strap being rotatably connected to the bracelet body, and an end of the first strap away from the bracelet body being chamfered, a second strap being provided on the end of the bracelet body away from the first strap, and the second strap being rotatably connected to the bracelet body, and the second strap and the first strap being parallel to each other, a skin-contacting slider being slidably installed on the outer surface of the bracelet body, and an end of the skin-contacting slider away from the bracelet body being designed as an arc surface, an elastic sliding mechanism being provided between the bracelet body and the skin-contacting slider, and the indwelling needle tube passing through the skin-contacting slider and the bracelet body being fixed by the elastic sliding mechanism.

[0005] Preferably, the elastic sliding mechanism includes: a first spring, the first spring is located inside the bracelet body, and the first spring is located between the bracelet body and the skin-contacting slider, a limiting friction block is fixedly installed on one end of the skin-contacting slider, and the outer surface of the limiting friction block is in contact with the outer surface of the indwelling needle tube, and the outer surface roughness of the limiting friction block is relatively high.

[0006] With the above technical solution, after inserting the needle, one only needs to open the skin-contact slider, place the needle tube of the indwelling needle into the interior of the limiting friction block and adjust the position. Then, the skin-contact slider is pushed back by the first spring, so that the two skin-contact sliders are close to each other, and the limiting friction block is clamped. The rough surface of the limiting friction block clamps and fixes the indwelling needle tube, so that the indwelling needle tube will not move at will and cause the indwelling needle tube to fall off.

[0007] Preferably, a snap-fit ​​fixing mechanism is slidably installed inside the bracelet body, which prevents the indwelling needle tube from sliding out and reduces the probability of movement of the indwelling needle tube.

[0008] The above technical solution can reduce the risk of the skin-contact slider automatically opening when the child moves his arm, causing the limiting friction block to separate from the indwelling needle tube and causing the indwelling needle tube to move.

[0009] Preferably, the snap fixing mechanism includes: a positioning slider, the positioning slider is slidably installed inside the bracelet body, and a second spring is provided between the bracelet body and the positioning slider, and one end of the positioning slider passes through the outer surface of the bracelet body, one end of the positioning slider is engaged with the skin-contacting slider, a pushing and fixing block is slidably installed on the outer surface of the bracelet body, and the outer surface of the pushing and fixing block is provided with anti-slip teeth, and elastic bracket blocks are fixedly installed on both sides of the pushing and fixing block, the elastic bracket blocks are engaged with the inner surface of the bracelet body, and the end of the positioning slider close to the pushing and fixing block is inclined, and the outer surface of one end of the pushing and fixing block is in contact with the outer surface of the positioning slider.

[0010] By adopting the above technical solution, the anti-slip teeth on the outer surface of the pushing fixing block are used to prevent the pushing fixing block from slipping after moving. At the same time, the pushing fixing block is fitted with the inclined surface of the positioning slider, so that the positioning slider is pressed down, and the positioning slider is inserted into the skin-contacting slider for fixation, so that the skin-contacting slider is fixed and cannot be accidentally opened to cause the indwelling needle tube to slide. At the same time, the elastic bracket block can fix the pushing fixing block in the bracelet body, so that the pushing fixing block will not slide accidentally.

[0011] Preferably, a penetration block is fixedly installed on the end of the second strap away from the bracelet body, and the outer surfaces of the penetration block, the skin-contact slider and the first strap are all affixed with cotton breathable stickers, the outer surface of the second strap is evenly provided with ventilation holes, and the outer surface of the second strap is penetrated by a fixing strap.

[0012] By adopting the above technical solution, the first strap, the skin-fitting slider and the interlaced block can be separated from the skin by a fitted cotton breathable sticker, so that the child's skin can be separated from the limiting bracelet and breathe, and breathe through the air holes, preventing the child's skin from being allergic and ulcerated due to long-term contact.

[0013] Preferably, an elastic snap-fit ​​mechanism is provided inside the insertion block, and the first watch strap can be quickly inserted and fixed through the elastic snap-fit ​​mechanism, making it more convenient and easy to wear the limit bracelet.

[0014] By adopting the above technical solution, after the first watchband is inserted into the inside of the insertion block, it can be quickly engaged and fixed, and the limiting bracelet can also be quickly removed, making it easier, more convenient and faster to wear the limiting bracelet.

[0015] Preferably, the elastic locking mechanism includes: a rotating tooth, which is rotatably installed inside the insertion block, and the outer surface of the insertion block is penetrated by the rotating shaft of the rotating tooth, and one end of the rotating tooth is located on the inner side of the insertion block, a torsion spring is provided between the insertion block and the rotating tooth, and the outer surface of the rotating tooth is in contact with the outer surface of the insertion block, and the rotating tooth is engaged with the block.

[0016] By adopting the above technical solution, after the first watchband is inserted, the moving block of the first watchband will lift and pass the rotating tooth, and at the same time the torsion spring will push the rotating tooth back to its original position, so that the rotating tooth is always engaged with the block. After the limit bracelet is fixed on the child's wrist, the first watchband is automatically fixed. When removing, it is only necessary to push the part of the rotating tooth exposed on the outer surface of the fixing block to disengage the block from the rotating tooth, so that the limit bracelet can be easily removed, and the tightness of the second watchband and the first watchband can be easily adjusted.

[0017] Compared with the prior art, the beneficial effects of the present invention are: the limiting bracelet for protecting the indwelling needle for children:

[0018] 1. After inserting the indwelling needle into the child's arm, simply pull open the skin-contact slider, place the indwelling needle tube into the limiting friction block and adjust the position. Then the first spring will push the skin-contact slider back, allowing the limiting friction block to clamp the indwelling needle tube. The rough outer surface of the limiting friction block fixes the indwelling needle tube, so that the indwelling needle tube will not move arbitrarily after wearing the limiting bracelet, causing the indwelling needle to slip out of the blood vessel.

[0019] 2. After wearing the fixed limit bracelet, in order to prevent the child from moving his arm at will and colliding with the first strap, which may cause the skin-contacting slider to open, it is only necessary to push the pushing fixing block so that the side surface of the pushing fixing block contacts the inclined surface of the positioning slider, and press the positioning slider down to compress the second spring, so that the positioning slider is inserted into the skin-contacting slider, so that the two skin-contacting sliders are fixed and the skin-contacting sliders cannot be opened. At the same time, the second spring will push the positioning slider toward the pushing fixing block to generate an extrusion force, and the elastic bracket block will engage with the bracelet body to fix the pushing fixing block, so that the skin-contacting slider cannot move, so that the limiting friction block will not accidentally open and cause the indwelling needle to move;

[0020] 3. When wearing the limit bracelet, you only need to insert the first strap into the interlaced block. When the first strap moves, it will drive the card block to move, so that the card block will push the rotating card tooth up and pass through. At the same time, the torsion spring will push the rotating card tooth back to its original position, so that the rotating card tooth is always engaged with the card block. After the limit bracelet is fixed on the wrist with appropriate tightness, the first strap can be automatically fixed without being disengaged or moved. Then, the overlong first strap can be inserted into the fixed strap. At the same time, the feeding accuracy of the limit bracelet can be conveniently adjusted. When disassembling, you only need to pull the part of the rotating card tooth on the outside of the interlaced block to disengage the rotating card tooth from the card block, so that the limit bracelet can be easily worn, adjusted and removed.

[0021] 4. The cotton breathable stickers attached to the outer surfaces of the first strap, the skin-contacting slider and the interlaced block allow air to pass between the skin and the first strap, the skin-contacting slider and the interlaced block after the limit bracelet is worn, thereby reducing allergies and ulcers on the child's skin caused by airtightness. At the same time, the cotton breathable stickers can be replaced, which is convenient for hygiene and cleanliness when the limit bracelet is used next time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] 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.

[0031] See also Figure 1-7 The utility model provides a technical solution: a limiting bracelet for protecting an indwelling needle in children, comprising a bracelet body 1, a first strap 2 being provided on the side surface of one end of the bracelet body 1, and the first strap 2 is rotatably connected to the bracelet body 1, and the end of the first strap 2 away from the bracelet body 1 is chamfered, a second strap 6 is provided on the end of the bracelet body 1 away from the first strap 2, and the second strap 6 is rotatably connected to the bracelet body 1, and the second strap 6 and the first strap 2 are parallel to each other, a skin-contacting slider 4 is slidably installed on the outer surface of the bracelet body 1, and the end of the skin-contacting slider 4 away from the bracelet body 1 is designed as an arc surface.

[0032] The arc surface design of the skin-fitting slider 4 enables the limiting bracelet to be well attached to the wrist, making it more comfortable to wear.

[0033] An elastic sliding mechanism is provided between the bracelet body 1 and the skin-contacting slider 4, and the indwelling needle tube passing through the skin-contacting slider 4 and the bracelet body 1 is fixed by the elastic sliding mechanism. The elastic sliding mechanism includes: a first spring 7, the first spring 7 is located inside the bracelet body 1, and the first spring 7 is located between the bracelet body 1 and the skin-contacting slider 4. A limiting friction block 5 is fixedly installed on one end of the skin-contacting slider 4, and the outer surface of the limiting friction block 5 is in contact with the outer surface of the indwelling needle tube, and the outer surface roughness of the limiting friction block 5 is relatively high.

[0034] After inserting the indwelling needle into the vein of the hand, it is only necessary to open the skin-contact slider 4 and place the indwelling needle tube between the limiting friction blocks 5, then adjust the position and release it, so that the first spring 7 can push the skin-contact slider 4 back and clamp the indwelling needle tube through the limiting friction blocks 5. The rough surface and clamping of the limiting friction blocks 5 prevent the indwelling needle tube from moving, and the fixation of the limiting bracelet reduces the probability of the indwelling needle moving out of the skin.

[0035] The inner sliding installation of the bracelet body 1 is equipped with a snap-fit ​​fixing mechanism, which prevents the indwelling needle tube from sliding out and reducing the chance of movement of the indwelling needle tube. The snap-fit ​​fixing mechanism includes: a positioning slider 8, which is slidably installed inside the bracelet body 1, and a second spring 9 is provided between the bracelet body 1 and the positioning slider 8, and one end of the positioning slider 8 passes through the outer surface of the bracelet body 1, and one end of the positioning slider 8 is engaged with the skin-contacting slider 4.

[0036] The second spring 9 will push the positioning slider 8 back to its original position, so that the positioning slider 8 is disengaged from the skin-contacting slider 4, reducing the chance of the skin-contacting slider 4 being opened due to the activeness of the child causing the bracelet body 1 to collide with foreign objects and the indwelling needle tube moving off.

[0037] An insertion block 13 is fixedly installed on the end of the second strap 6 away from the bracelet body 1, and the outer surfaces of the insertion block 13, the skin-contact slider 4 and the first strap 2 are all affixed with a cotton breathable sticker 16. The outer surface of the second strap 6 is evenly provided with ventilation holes 12, and the outer surface of the second strap 6 is penetrated by a fixing belt.

[0038] The second strap 6 can be breathable through the ventilation holes 12, and the cotton breathable sticker 16 attached to the outer surface of the first strap 2, the skin-contact slider 4 and the interlaced block 13 can separate the wrist skin from the outer surface of the limit bracelet and allow ventilation, thereby reducing the allergic itching and even ulceration caused by the skin's lack of air permeability in young children. At the same time, after use, the limit bracelet can be disinfected and the cotton breathable sticker 16 can be replaced for the next use.

[0039] An elastic locking mechanism is provided inside the insertion block 13, through which the first watchband 2 can be quickly inserted and fixed, making it more convenient and easy to wear the limit bracelet.

[0040] When the wristband is worn, it is only necessary to insert the first strap 2 into the inside of the insertion block 13. The chamfered design at one end of the first strap 2 makes it easier to insert the insertion block 13. As the first strap 2 moves, the card block 3 will push the rotating card tooth 14 open and pass through, and the torsion spring 15 will push the rotating card tooth 14 back to its original position, so that the rotating card tooth 14 is always engaged with the card block 3, so that the wristband is fixed on the wrist with a suitable tightness. The first strap 2 can be automatically fixed without loosening, and it is convenient to adjust the length of the first strap 2 and the second strap 6, which is convenient for adjusting the tightness of the wristband. At the same time, when the wristband needs to be removed, it is only necessary to turn the rotating card tooth 14 on the outside of the insertion block 13 to disengage the rotating card tooth 14 from the card block 3, so that the first strap 2 can be pulled out of the insertion block 13, so that the wristband can be conveniently fixed, adjusted and removed.
