[0027] The present invention has the following beneficial effects:

[0028] 1. This neurology infusion care device consists of a transparent puncture cone, a transparent tube, and a needle that are nested in sequence. The three components work together effectively. First, the transparent puncture cone is used to accurately locate the blood vessel. The curved notch on the handle of the transparent puncture cone slides against the skin, minimizing needle deflection and damage to surrounding tissue during insertion. Next, the needle can be pushed into the blood vessel, and the depth can be measured using the second scale mark engraved on the needle and the standard line on the transparent puncture cone. During the insertion of the needle, the vertically designed, more ergonomic second handle facilitates pushing, while the sliding fit of the guide bar and guide groove ensures the linear sliding stability of the needle. This greatly facilitates needle insertion during infusion and enhances needle stability, making it more reliable than traditional surgical procedures that rely on the physician's experience.

[0029] 2. This neurological infusion nursing device further features a transparent puncture cone that can be attached to the wrist via a mounting frame to adjust the insertion angle. The transparent puncture cone slides along the through-hole of the mounting plate, and the limiting cooperation of a plurality of first limiting grooves and a plurality of limiting blocks further enhances the sliding stability of the transparent puncture cone and prevents deflection. By rotating any of the third handles from the side, the second bevel gear and the first bevel gear can change the transmission direction to drive the screw to rotate, thereby driving the nut to slide back and forth. The nut then drives the first rotating rod and the mounting plate through the transmission of the two telescopic rods to rotate and adjust the insertion angle of the transparent puncture cone. The self-locking properties of the screw and nut are used to fix the angle.

[0030] 3. This neurological infusion nursing device, further, through the design of the fixing mechanism, can fix the wrist through the bracelet composed of a fixed ring part, two rotating ring parts and two telescopic ring parts, so that there is no need to hold and fix the transparent puncture cone during the operation, and both the angle and position are fixed, which facilitates the needle insertion during the infusion. In addition, the two telescopic ring parts are retractable, so that the bracelet can be adjusted independently according to the size of the patient's wrist, making the fixation more firm and stable. First, press the button to drive the two rotating ring parts to flip open, and at the same time drive the two clips to clamp the two elastic clips and then clamp the position of the two telescopic ring parts. Then, after putting the opened bracelet on the wrist, just release the button, so that the button rebounds under the drive of the two third springs, driving the two rotating ring parts to flip and close, and the two telescopic ring parts are also buckled together under the elastic force of the two first springs to achieve the size adjustment of the bracelet.

DETAILED DESCRIPTION

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0042] For example 1, please refer to Figures 1-9 A neurological infusion care device includes a transparent puncture cone 100, a transparent tube 200 and a needle 300, and is characterized in that: the transparent puncture cone 100 is provided with a hand-held portion 110, the hand-held portion 110 is provided with an arc-shaped notch portion 120 and a first handle 130, and the transparent puncture cone 100 is provided with a guide groove 140.

[0043] The transparent tube 200 is slidably disposed in the transparent puncture cone 100 . A guide bar 210 is provided on the transparent tube 200 , and the guide bar 210 is slidably disposed in the guide groove 140 . A second handle 220 is provided on the guide bar 210 , and the needle 300 is slidably disposed in the transparent tube 200 .

[0044] The transparent puncture cone 100 is provided with a depth measuring mechanism 400 , which includes a standard line 410 provided on the transparent puncture cone 100 , a first scale line 420 provided on the transparent tube 200 , and a second scale line 430 provided on the needle 300 .

[0045] In this embodiment, the transparent puncture cone 100 is a tubular structure with a pointed end. A guide groove 140 extending along the central axis is formed on the surface of the transparent puncture cone 100. The handle 110 is a disc-shaped structure. The transparent puncture cone 100 is vertically fixed at the center of the handle 110. A through hole is provided at the center of the handle 110, which communicates with the transparent puncture cone 100. During use, the hand can hold the handle 110 or place it under the handle 110. The handle 110 is provided with an arc-shaped notch 120. With conventional instruments, if the transparent puncture cone 100 deflects during surgery, it can affect surgical accuracy and even safety. The arc-shaped notch 120 forms a snap fit with the operator's skin, thereby ensuring that the transparent puncture cone 100 does not rotate to the greatest extent possible.

[0046] The transparent tube 200 is an overall tubular structure, with a guide strip 210 provided on its surface. The guide strip 210 slidably engages with the guide groove 140. To ensure the precise movement of the needle 300, a standard line 410 is provided on the outer wall of the transparent puncture cone 100. A first scale mark 420 is also provided on the transparent tube 200, allowing the surgeon to monitor the cutting depth in real time. The transparent tube 200 also features an upwardly extending second handle 220, which changes the traditional linear design. This makes pushing the transparent tube 200 more ergonomic, simpler, and more labor-saving, while also improving efficiency.

[0047] In order to facilitate the determination of the acupuncture depth, a second scale line 430 is provided on the outer wall of the needle 300 to determine the cutting depth. After the transparent tube 200 determines the starting position, it can be advanced according to the insertion depth.

[0048] Example 2: This example is an improvement based on Example 1. For details, please refer to Figure 1-Figure 5 The infusion nursing device for neurology further includes a mounting frame 500 , on which a first rotating rod 510 is rotatably provided. A mounting plate 520 is provided on the first rotating rod 510 , and a transparent puncture cone 100 is slidably provided on the mounting plate 520 .

[0049] A plurality of first limiting grooves 530 are formed on the mounting plate 520 , and a plurality of limiting blocks 540 are provided on the transparent puncture cone 100 . The limiting blocks 540 are slidably disposed in the plurality of first limiting grooves 530 .

[0050] In this embodiment, the lower portion of the mounting frame 500 also features an arc-shaped notch, allowing it to fit snugly around the patient's wrist. The ends of a first rotating rod 510 are pivotally mounted to the inner walls of the mounting frame 500. A mounting plate 520 is secured to the first rotating rod 510, and the transparent puncture cone 100 is slidably mounted in the central through-hole of the mounting plate 520.

[0051] Furthermore, the four limiting blocks 540 fixed on the transparent puncture cone 100 slide along the four first limiting grooves 530 opened at the through hole of the mounting plate 520, thereby further enhancing the sliding stability of the transparent puncture cone 100 and preventing deflection.

[0052] Example 3: This example is an improvement made on the basis of Example 2. For details, please refer to Figure 1-Figure 5 An angle adjustment mechanism 600 is provided on the mounting frame 500. The angle adjustment mechanism 600 is used to control the rotation of the first rotating rod 510. The angle adjustment mechanism 600 includes a second limiting groove 610 opened on the mounting frame 500. A nut 620 is slidably provided in the second limiting groove 610, and a connecting rod 630 is provided on the nut 620.

[0053] The angle adjustment mechanism 600 further includes two telescopic rods 640 , and two ends of the two telescopic rods 640 are respectively disposed on the first rotating rod 510 and the connecting rod 630 .

[0054] The angle adjustment mechanism 600 further includes a screw rod 650 rotatably disposed on the mounting frame 500 , and the nut 620 is threadedly connected to the screw rod 650 .

[0055] A first bevel gear 660 is provided on the screw rod 650 , a second rotating rod 670 is rotatably provided on the mounting frame 500 , a second bevel gear 680 and a third handle 690 are provided on the second rotating rod 670 , and the second bevel gear 680 is meshed with the first bevel gear 660 .

[0056] Two second rotating rods 670 , two second bevel gears 680 and two third handles 690 are symmetrically provided on the mounting frame 500 .

[0057] In this embodiment, a second limiting groove 610 is opened on the lower inner wall of the installation frame 500 , and a nut 620 slides back and forth along the second limiting groove 610 . A connecting rod 630 is fixed on the nut 620 .

[0058] The structure of the telescopic rod 640 is as follows Figure 9 As shown, it is composed of two telescopic sections, one end of the two telescopic rods 640 is respectively fixed on the first rotating rod 510, and the other end of the two telescopic rods 640 is respectively rotatably mounted on the connecting rod 630.

[0059] The two ends of the screw rod 650 are respectively rotatably mounted on the front and rear inner walls of the mounting frame 500. A first bevel gear 660 is fixed on the surface of the screw rod 650. The two second rotating rods 670 are movable through the left and right side walls of the mounting frame 500 respectively. Second bevel gears 680 are fixed on the surfaces of the two second rotating rods 670 located on the inner side of the mounting frame 500. Third handles 690 are fixed to the parts of the two second rotating rods 670 located on the outer side of the mounting frame 500.

[0060] By rotating a third handle 690, the second rotating rod 670 and the second bevel gear 680 can be driven to rotate, thereby driving the first bevel gear 660 and the screw rod 650 to rotate forward and reverse, so that the nut 620 slides back and forth under the limit of the second limit groove 610, and then the first rotating rod 510 and the mounting plate 520 are driven by the transmission of the two telescopic rods 640 to deflect to achieve angle adjustment of the transparent puncture cone 100.

[0061] The purpose of changing the transmission direction by the second bevel gear 680 and the first bevel gear 660 is to facilitate the doctor to adjust the angle from the side, which is in line with the convenience of actual operation. The third handle 690 is provided on each side to facilitate the doctor to adjust the angle from either side.

[0062] Example 4: This example is an improvement made on the basis of Example 3. For details, please refer to Figures 1-8 A fixing mechanism 700 is also provided on the mounting frame 500. The fixing mechanism 700 is used to fix the mounting frame 500 to the patient's wrist. The fixing mechanism 700 includes a fixing ring portion 710 provided on the mounting frame 500. A support plate 720 is provided in the fixing ring portion 710.

[0063] Two rotating rings 730 are rotatably provided on the support plate 720, and the two rotating rings 730 are symmetrically arranged based on the support plate 720. Both rotating rings 730 are provided with connecting arms 740, and both connecting arms 740 are provided with rotating ring parts 750. Both rotating ring parts 750 are slidably provided with telescopic ring parts 760.

[0064] Latex pads 770 are provided on the fixed ring portion 710 , the two rotating ring portions 750 and the two telescopic ring portions 760 .

[0065] In this embodiment: a fixed ring portion 710 is fixed at the lower end of the mounting frame 500, a support plate 720 is fixed to the inner wall of the fixed ring portion 710, two rotating rings 730 are symmetrically mounted on the support plate 720 for left and right rotation, a connecting arm 740 is fixed to each of the two rotating rings 730, a rotating ring portion 750 is fixed to each of the two connecting arms 740, and a telescopic ring portion 760 is slidably mounted on each of the two rotating ring portions 750.

[0066] A wristband for fixing the patient's wrist is composed of a fixed ring part 710, two rotating ring parts 750 and two telescopic ring parts 760, and latex pads 770 are provided on the inner sides of the five parts to increase friction and increase fixation stability.

[0067] Example 5: This example is an improvement made on the basis of Example 4. For details, please refer to Figures 1-6 The fixed ring portion 710 is provided with a length adjustment mechanism 800, which is used to control the expansion and contraction of the two telescopic ring portions 760 to adapt to the patient's wrist size.

[0068] The length adjustment mechanism 800 includes two first springs 810 respectively disposed on the two telescopic ring portions 760 , and the two first springs 810 are respectively connected to the inner walls of the two rotating ring portions 750 .

[0069] The length adjustment mechanism 800 further includes two elastic buckles 820 respectively disposed in the two rotating ring parts 750 . A serrated groove 830 is provided in each of the two telescopic ring parts 760 , and the two elastic buckles 820 are respectively matched with the two serrated grooves 830 .

[0070] A clamping strip 840 is slidably disposed in each of the two elastic buckles 820 . A second spring 850 is disposed on each of the two clamping strips 840 , and both of the second springs 850 are connected to the inner wall of the fixing ring portion 710 .

[0071] In this embodiment, the two ends of the two first springs 810 are respectively fixed to the two telescopic rings 760 and the inner walls of the two rotating rings 750. The elastic force provided by the two first springs 810 pushes the two telescopic rings 760 until they come into contact and stop, thereby expanding the diameter of the bracelet to accommodate wrists of different sizes.

[0072] Furthermore, in order to prevent the two telescopic ring parts 760 from popping out and obstructing the fixing operation when the bracelet is opened and fixed to the wrist, elastic buckles 820 are fixed on the inner walls of the two rotating ring parts 750, and serrated grooves 830 are opened on the inner walls of the two telescopic ring parts 760.

[0073] When the two clips 840 are pulled by the two second springs 850 and located in the middle position of the two elastic clips 820, the head positions of the two elastic clips 820 can be compressed and rebounded due to their elastic material. At this time, the two telescopic ring parts 760 can be freely expanded and contracted, and at this time, the two elastic clips 820 will continue to compress and rebound under the drive of the two serrated grooves 830.

[0074] When the two clamping strips 840 slide toward the heads of the two elastic buckles 820 and clamp them so that they cannot be compressed and rebounded, the positions of the two telescopic ring parts 760 are fixed.

[0075] Example 6: This example is an improvement based on Example 5. Figures 1-8 A driving mechanism 900 is also provided on the fixed ring portion 710. The driving mechanism 900 includes a button 910 slidably provided on the fixed ring portion 710. Two screws 920 are symmetrically provided on the button 910, and the thread directions of the two screws 920 are opposite.

[0076] A plurality of guide blocks 930 are provided on each of the two rotating rings 730 , and the guide blocks 930 are slidably disposed in the thread grooves of the two screw rods 920 .

[0077] The driving mechanism 900 further includes a push block 940 slidably disposed within the fixed ring portion 710 , and the push block 940 is adapted to both the clamping strips 840 , and both the screw rods 920 are rotatably disposed on the push block 940 .

[0078] Two third springs 950 are symmetrically arranged on the button 910 , and both third springs 950 are connected to the inner wall of the fixing ring portion 710 .

[0079] In this embodiment: when the button 910 is pressed backward, the two third springs 950 will be stretched and the two screw rods 920 will be driven to move backward. At this time, the guiding effect of the several guide blocks 930 fixed to the inner walls of the two rotating rings 730 will drive the two rotating rings 730 to rotate, and then drive the two rotating ring parts 750 to rotate in the opposite direction to open. At this time, the push block 940 will also be driven by the two screw rods 920 to move backward, pushing the two clamping strips 840 to clamp the two telescopic ring parts 760.

[0080] After being put on the wrist, it is only necessary to release the button 910 to reset it under the rebound action of the two third springs 950, so that the two third springs 950 can be deflected and the two telescopic ring parts 760 can be expanded and contracted accordingly.

[0081] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0082] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
