[0002] An intravenous needle refers to a needle that is inserted into a blood vessel once for long-term or repeated infusions and can be reused multiple times. It is usually left on the back of the patient's hand or arm to reduce the pain of multiple injections, especially for obese children. The use of intravenous needles can reduce the pain caused by repeated intravenous punctures in children and their fear of injections, reduce the anxiety of parents, facilitate clinical medication, emergency medication for emergency and critically ill patients, reduce the workload of nurses, and reduce the pain of children. Therefore, intravenous needles are widely used in clinical practice. Faced with this special group of children, the length of time the intravenous needle is left in place and the comfort of the child have become the most concerned issues for nurses and parents, and are also the signs of the successful use of intravenous needles and the premise of their promotion.

[0003] The current indwelling needle protective cover conventionally uses a sock cover or an adhesive cover to cover the indwelling needle to protect the indwelling needle. However, during the infusion process, children may accidentally drag the infusion tube, causing the indwelling needle to be pulled out, thereby affecting the infusion. For this reason, we propose a protective cover that prevents patients from removing the indwelling needle by themselves. Utility Model Content

[0004] The utility model aims to provide a protective cover for preventing a patient from removing an indwelling needle by himself, so as to solve the problems raised in the above-mentioned background technology.

[0008] A locking piece is provided on the inner side of the fixing ring for clamping and fixing the infusion tube. When the slide plate moves downward with the locking piece, the locking piece can fix the infusion tube, so that children cannot pull the indwelling needle by pulling the infusion tube, causing the indwelling needle to be pulled out and causing infusion failure.

[0009] Preferably, the locking member includes a guide groove, a guide groove is provided in the groove on the inner side of the fixing ring, a sliding rod is slidably installed on the inner side of the guide groove, the sliding rod passes through the slide plate and is slidably connected to the slide plate, a support rod is hinged on the side of the sliding rod close to the center of the fixing ring, a torsion spring is fixed on one side of the support rod, an end of the torsion spring away from the support rod is fixed to the sliding rod, a rubber block is fixed on the other side of the support rod, an arc-shaped clamping plate is fixed on the side of the support rod close to the torsion spring, and a protrusion is fixed on the inner side of the groove, when the slide plate moves downward, the sliding rod can move along the guide groove, and the sliding rod brings the support rod to gradually move to the side close to the center of the slide plate. After moving to the position of the protrusion, the protrusion can contact the rubber block to push the support rod to swing to the side away from the protrusion at the position hinged with the sliding rod, and the support rod clamps the infusion tube with the arc-shaped splint. Through the rubber arc-shaped splint, when the arc-shaped splint clamps the infusion tube, the friction between the infusion tube and the infusion tube can be increased, which effectively prevents children from pulling the infusion tube, causing the infusion tube to pull the indwelling needle and causing the indwelling needle to be pulled out. When the arc-shaped splint clamps the infusion tube, the arc-shaped splint cannot continue to move, and then the support rod cannot continue to fold. At this time, the protrusion is squeezed on the rubber block, causing the rubber block to deform to a certain extent, which will not cause excessive clamping force on the infusion tube.

[0010] Preferably, two groups of locking members are provided and the two groups of locking members are symmetrically arranged with the center line of the fixing ring as the symmetry axis. The two groups of locking members cooperate with each other to stably clamp the infusion tube.

[0012] Preferably, a driven component is provided on the surface of the fixed ring, and the driven component includes a collar, a slider is fixed on the inner side of the collar, an annular groove and a movable groove are provided on the surface of the fixed ring, a through groove is provided on the surface of the fixed ring, the annular groove and the movable groove are communicated with each other, the slider is slidably installed on the inner side of the annular groove, and a connecting rod is abutted at the bottom of the collar, the connecting rod passes through the through groove, and the end of the connecting rod away from the collar is fixed to the slide plate, when the slide plate is in the annular groove, the collar can be limited, thereby limiting the slide plate by the connecting rod, and when the collar is rotated, the collar brings the slider to rotate into the movable groove, so that the collar can be pushed downward, and the collar can move together with the slide plate by abutting the connecting rod.

[0013] Preferably, a through hole is opened on the surface of the glove, and a transparent observation window is fixed on the inner side of the through hole, through which the situation of the indwelling needle can be observed.

[0014] Compared with the prior art, the utility model provides a protective cover for preventing patients from removing the indwelling needle by themselves, which has the following beneficial effects:

[0015] 1. The protective cover for preventing patients from removing the indwelling needle by themselves, through the protective component and the driven component, after the gloves and the fixing ring are put on the hands of children, by moving the infusion tube to the middle area of ​​the back of the child's hand, rotating the ring and pulling the ring downward, the locking part can be controlled to fix the infusion tube, so that the child cannot pull the indwelling needle by pulling the infusion tube, causing the indwelling needle to be pulled out, resulting in infusion failure.

[0022] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a protective cover for preventing a patient from removing an indwelling needle by himself, comprising a glove 1, an elastic band 2 is arranged on the glove 1, a through hole is opened on the surface of the glove 1, a transparent observation window 6 is fixed on the inner side of the through hole, and the situation of the indwelling needle can be penetrated through the transparent observation window 6, and a protective component 3 is arranged at the bottom of the glove 1, and the protective component 3 includes: a fixing ring 31, a groove 32, a slide plate 33, a connecting spring 34, and a locking member 35.

[0023] The fixing ring 31 is fixed to the bottom of the glove 1, and a groove 32 is provided on the inner side of the fixing ring 31. The slide plate 33 is slidably installed on the inner side of the groove 32. A connecting spring 34 is fixed on the inner side of the groove 32. The end of the connecting spring 34 away from the groove 32 is fixedly connected to the slide plate 33. A locking piece 35 is provided on the inner side of the fixing ring 31. When the slide plate 33 moves downward with the locking piece 35, the locking piece 35 can fix the infusion tube, so that children cannot pull the indwelling needle by pulling the infusion tube, causing the indwelling needle to be pulled out and causing infusion failure. A transverse groove 5 is provided on the slide plate 33 for the slide bar 352 to move left and right. Two groups of locking pieces 35 are provided, and the two groups of locking pieces 35 are symmetrically arranged with the center line of the fixing ring 31 as the symmetry axis. The two groups of locking pieces 35 cooperate with each other to stably clamp the infusion tube.

[0024] The locking member 35 includes a guide groove 351. The groove 32 on the inner side of the fixing ring 31 is provided with a guide groove 351. A slide bar 352 is slidably installed on the inner side of the guide groove 351. The slide bar 352 penetrates the slide plate 33 and is slidably connected to the slide plate 33. A support rod 353 is hinged on the side of the slide bar 352 close to the center of the fixing ring 31. A torsion spring 354 is fixed to one side of the support rod 353. The end of the torsion spring 354 away from the support rod 353 is fixed to the slide bar 352. A rubber block 355 is fixed to the other side of the support rod 353. An arc-shaped clamping plate 356 is fixed to the side of the support rod 353 close to the torsion spring 354. A protrusion 357 is fixed to the inner side of the groove 32. When the slide plate 33 moves downward, the slide bar 352 can move along the guide groove 351, and the slide bar 352 gradually moves to the side close to the center of the slide plate 33 with the support rod 353. When the support rod 353 moves to the position of the protrusion 357, the protrusion 357 can contact the rubber block 355 to push the support rod 353 to swing to the side away from the protrusion 357 at the position hinged with the sliding rod 352. The support rod 353 clamps the infusion tube with the arc-shaped splint 356. Through the rubber arc-shaped splint 356, when the arc-shaped splint 356 clamps the infusion tube, the friction between the infusion tube and the arc-shaped splint 356 can be increased, which effectively prevents children from pulling the infusion tube, causing the infusion tube to pull the indwelling needle and causing the indwelling needle to be pulled out. When the arc-shaped splint 356 clamps the infusion tube, the arc-shaped splint 356 cannot continue to move, and then the support rod 353 cannot continue to fold. At this time, the protrusion 357 is squeezed on the rubber block 355, causing the rubber block 355 to deform to a certain extent, and will not cause excessive clamping force on the infusion tube.

[0025] A driven component 4 is provided on the surface of the fixed ring 31, and the driven component 4 includes a collar 41, and a slider 42 is fixed on the inner side of the collar 41. An annular groove 43 and a movable groove 44 are provided on the surface of the fixed ring 31. A through groove 45 is provided on the surface of the fixed ring 31. The annular groove 43 and the movable groove 44 are communicated with each other. The slider 42 is slidably installed on the inner side of the annular groove 43. A connecting rod 46 is abutted at the bottom of the collar 41. The connecting rod 46 passes through the through groove 45. The end of the connecting rod 46 away from the collar 41 is fixed to the slide plate 33. When the slide plate 42 is in the annular groove 43, the collar 41 can be limited, so that the slide plate 33 is limited by the connecting rod 46. When the collar 41 is rotated, the collar 41 rotates with the slider 42 into the movable groove 44, and the collar 41 can be pushed downward. The collar 41 can move with the slide plate 33 by abutting the connecting rod 46.

[0026] Based on the above embodiment, the elastic band 2 is stretched open, the glove 1 and the fixing ring 31 are put on the child's hand, the infusion tube of the indwelling needle is placed in the middle area of ​​the back of the child's hand, the ring 41 is rotated, and the ring 41 rotates with the slider 42 into the moving groove 44, and the ring 41 is pushed downward. The ring 41 can move with the slide plate 33 by contacting the connecting rod 46, and the slide plate 33 moves with the slide bar 352. The slide bar 352 can move along the guide groove 351, and the slide bar 352 and the support rod 353 gradually move close to the slide plate 33. The support rod 353 moves to one side of the center, and when the support rod 353 moves to the position of the protrusion 357, the protrusion 357 can abut against the rubber block 355 to push the support rod 353 to swing to the side away from the protrusion 357 at the position hinged with the sliding rod 352, and the support rod 353 carries the arc-shaped splint 356 to clamp the infusion tube. The arc-shaped splint 356 made of rubber can increase the friction between the infusion tube and the infusion tube after clamping the infusion tube, effectively preventing children from pulling the infusion tube, causing the infusion tube to pull the indwelling needle and causing the indwelling needle to be pulled out.

[0027] When the collar 41 cannot be pushed downward any further, the collar 41 moves with the slider 42 into another set of annular grooves 43. The collar 41 is rotated, and the slider 42 moves into the annular grooves 43. The collar 41 limits the slide plate 33 by abutting against the connecting rod 46 to ensure stability during use.

[0028] When the glove 1 needs to be taken off, the ring 41 only needs to be rotated again. The ring 41 moves with the slider 42 to the position of the moving groove 44, and the connecting rod 46 is no longer resisted. Under the action of the connecting spring 34, the slide plate 33 returns with the slider 352, and the slider 352 returns along the guide groove 351, so that the two groups of sliders 352 move away from each other, thereby loosening the fixation of the indwelling needle infusion tube, and the rubber block 355 is no longer resisted by the protrusion 357. Under the action of the torsion spring 354, the support rod 353 returns with the arc splint 356, and the device is reset. After the elastic band 2 is stretched open, the glove 1 and the fixing ring 31 can be taken off.

[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
