[0042] The technical solution of the present utility model is further described with reference to the following embodiments.
[0043] Example 1
[0044] A terminal, such as Figures 1 to 3 As shown, a terminal body 100, a clip 200 for clamping needle tubes 600 of different specifications, two fixed arms 300 for fixing the needle tubes 600, and at least one pair of fixed wings 400 for fixing the wires 700 are provided. The clip 200 is integrally connected to the upper end of the terminal body 100, and the two fixed arms 300 are integrally connected to both sides of the upper end of the terminal body 100 and bent toward each other to form an enclosed frame-like structure. The surface of the clip 200 and an inner wall surface of the frame-like structure constitute two opposing clamping surfaces for fixing the needle tube 600. The fixed wings 400 are integrally connected to the lower end of the terminal body 100. Each pair of fixed wings 400 has an inwardly bent structure.
[0045] It should be noted that the liquid outlet direction of the needle tube 600 is defined as the upper end of the terminal. The end of the needle tube 600 is inserted into the frame structure enclosed by the present invention from the upper end of the terminal body 100, and the clip 200 presses the needle tube 600 against the frame structure, thereby fixing the needle tube 600. Figure 4It should also be noted that the number of pairs of fixing wings 400 can be determined based on actual conditions, such as the size and material of the wire 700. This embodiment uses two pairs of fixing wings 400 as an example for description. The two pairs of fixing wings 400 are integrally connected to the lower end of the terminal body 100 from top to bottom. Of course, for wires 700 with smaller diameters, a single pair of fixing wings 400 can also be used.
[0046] The fixing wings 400 of the present invention fix the wires 700 specifically by placing the ends of the wires 700 between the fixing wings 400 and then bending each pair of fixing wings 400 inwards to fix the wires.
[0047] The clip 200 is a triangular structure formed by three bends, such as Figure 5 The end where the clip 200 is connected to the terminal body 100 is taken as the starting point, and three bends are defined in sequence as the first bend, the second bend, and the third bend. The first bend is located outside the frame structure, the second bend is located inside the frame structure and serves as one of the clamping surfaces, and the third bend is opposite to the inner surface of the frame structure.
[0048] In the terminal of the present invention, there is a gap between a fixed arm 300 and an adjacent fixed wing 400 located on the same side of the terminal body 100. The length of the gap is defined as A, and there is a condition of 1mm≤A≤5mm. Figure 5 The terminal is further provided with a tilting tongue 500 , which is integrally connected to the upper end of the terminal body 100 and tilts out in a direction away from the clip 200 . The terminal body 100 is provided with a through hole 110 , and the tilting tongue 500 is located outside the through hole 110 .
[0049] It should be noted that the gap A of the present invention prevents the wire 700 from blocking the end of the needle tube 600, thereby obstructing the flow of fluid. Furthermore, the tongue 500 improves the stability of the terminal during injection molding of the external needle hub 800, and the through hole 110 serves as another channel for the fluid to enter the needle tube 600.
[0050] It should also be noted that the terminals of the present invention are punched out of sheet materials. Figure 6 Then follow Figure 6 It is made by bending the dotted line in the figure.
[0051] The terminal's clip 200 and fixed arm 300 allow the needle tube 600 to be directly inserted into the two clamping surfaces, while the wire 700 is secured via the fixed wing 400, eliminating the need for welding. Furthermore, this terminal can directly accommodate needle tubes 600 of varying specifications. Therefore, this utility model simplifies the production process and reduces production costs. Furthermore, the needle tube 600 and wire 700 are respectively fixed to the upper and lower ends of the terminal body 100, ultimately reducing the overall width of the needle holder.
[0052] Example 2
[0053] A terminal, such as Figure 6 , other features are the same as those of embodiment 1, except that: the clip 200 is formed by at least two bendings, and this embodiment takes two bendings as an example.
[0054] The end where the clip 200 connects to the terminal body 100 is the starting point, and two bends are defined as the first bend and the second bend, respectively. The first bend is located outside the frame structure, while the second bend is located inside the frame structure and serves as one of the clamping surfaces. An arc structure is formed between the first bend and the second bend.
[0055] Compared with embodiment 1, this embodiment is suitable for a needle tube 600 with a relatively larger diameter.
[0056] Example 3
[0057] A continuous nerve stimulation needle with terminals, such as Figure 7 , provided with a terminal, a needle tube 600, a wire 700 and a needle seat 800 as in embodiment 1 or 2, one end of the needle tube 600 is inserted into the upper end of the terminal body 100, one end of the wire 700 is fixed to the lower end of the terminal body 100, and the terminal, one end of the needle tube 600 and one end of the wire 700 are all sealed inside the needle seat 800, and the other end of the wire 700 is led out from the side of the needle seat 800.
[0058] The end of the needle hub 800 is integrally connected with a Luer connector 810 .
[0059] It should also be pointed out that in order to further prevent the wire 700 from blocking the needle tube 600, the terminal is usually bent before the terminal is injection molded with the needle seat 800. Specifically, the lower end of the terminal body 100 is bent toward the tongue 500. The specific bending angle is based on the actual size of the needle seat 800 and other actual conditions. Generally, the lower end of the terminal body 100 and the upper end of the terminal body 100 are bent at about 150°, such as Figure 8 .
[0060] The continuous nerve stimulation needle with a terminal has a terminal that can directly plug the needle tube 600 into the two clamping surfaces through the clip 200 and the fixed arm 300, and the wire 700 is fixed by the fixed wing 400, without the need for welding and fixing. Moreover, this terminal can directly plug and fix needle tubes 600 of different specifications. Therefore, the utility model can simplify the production process and reduce production costs. Moreover, in the terminal, the needle tube 600 and the wire 700 are respectively fixed at the upper and lower ends of the terminal body 100, thereby reducing the overall width of the needle seat 800. The continuous nerve stimulation needle is also connected to a Luer connector 810 to better improve the convenience of use.
[0061] Example 4
[0062] A continuous nerve stimulation needle with terminals, such as Figure 9 and Figure 10 , other features are the same as those of Example 3, and also have the following technical features: this embodiment is further provided with an outer sleeve 900 and a hose 1000, and the outer sleeve 900 can be detachably mounted on the outside of the needle tube 600.
[0063] The outer tube 900 is provided with a tube body 910 and an outer tube seat 920. One end of the tube body 910 is fixedly assembled on the outer tube seat 920. The needle tube 600 is detachable and passes through the outer tube seat 920 and the tube body 910 in sequence, and the outer tube seat 920 is in contact with the needle seat 800.
[0064] When the outer tube 900 is disassembled from the needle tube 600 and the needle seat 800, the hose 1000 and the outer tube 900 can be disassembled and assembled, and the hose 1000 sequentially passes through the tube body 910 and the outer tube seat 920. Figure 11 .
[0065] It should be noted that, after the continuous nerve stimulation operation is completed, the continuous nerve stimulation needle of this embodiment can remove the terminal, needle tube 600, wire 700 and needle seat 800 as a whole, while the outer sleeve 900 remains in the body to form a channel, and then one end of the hose 1000 is inserted into the body from the outer sleeve 900. After the hose 1000 is in place, the outer sleeve 900 is removed from the other end of the hose 1000, and finally the hose 1000 is left in the human body. Subsequently, it is only necessary to connect the corresponding connector at the other end of the hose 1000 to continuously infuse fluid into the user's body.
[0066] Compared with Example 3, the continuous nerve stimulation needle with a terminal in this embodiment can perform subsequent continuous injection operations, avoiding multiple punctures on the user.
[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
