[0037] The following will describe in detail some embodiments of the present utility model with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0038] As Figures 1 to 3 shown, an intravenous needle feeding device provided by an embodiment of the present utility model includes a linear vibrator 20 and a material distribution mechanism 10 connected to the linear vibrator 20. The material distribution mechanism 10 includes a first material channel member 100 and a second material channel member 200: a plurality of first material channel members 100 are arranged in parallel in sequence, and a first material distribution channel 110 for an intravenous needle to pass through is arranged on the first material channel member 100; a plurality of second material channel members 200 are arranged at intervals to enclose and form a second material distribution channel 210. The second material distribution channel 210 is arranged vertically at the bottom of the first material channel member 100. One end of the second material channel member 200 is connected to the first material channel member 100, and the second material channel member 200 and the first material channel member 100 are arranged at an angle in the vertical direction.

[0039] That is, for the intravenous needle feeding device provided by the embodiment of the present utility model, by connecting the second material channel member 200 and the first material channel member 100, it is ensured that the feeding ports of the first material distribution channel 110 and the second material distribution channel 210 can coincide, which is convenient for the docking of the intravenous needle with the two material distribution channels. At the same time, by arranging the second material channel member 200 and the first material channel member 100 at an angle in the vertical direction, the distance between the first material distribution channel 110 and the second material distribution channel 210 gradually increases, and the flexible catheter is gradually smoothed out, solving the technical problems in the prior art that it is difficult for the flexible catheter to dock with the inlet of the double-layer guide plate, resulting in material jamming and mutual entanglement between flexible catheters, and improving the feeding efficiency and stability of the intravenous needle.

[0040] Specifically, the first material channel member 100 is integrally arranged in a long strip shape and can be made by bending and welding metal plate members. All the first material channel members 100 are arranged in parallel and are integrally arranged in the horizontal direction. The first material channel members 100 can be connected by connecting blocks and bolts. The cross-section of the first material distribution channel 110 is in a "V" shape and is arranged along the extending direction of the first material channel member 100. An opening groove is provided at the bottom of the first material distribution channel 110, so that the venous needle can be clamped onto the opening groove, and the flexible catheter of the venous needle can naturally hang down along the opening groove. The linear vibrator 20 is fixed below the first material channel member 100 by bolts. By means of the linear vibrator 20, the first material channel member 100 can be vibrated, so that the venous needle can gradually vibrate from the inlet of the first material distribution channel 110 to the outlet of the first material distribution channel 110. The second material channel member 200 is arranged in a rectangular flat plate shape and is arranged at a certain angle to the horizontal direction directly below the first material channel member 100. In this embodiment, the second material channel member 200 is arranged at an angle of 60 degrees to the horizontal direction, and the second material channel members 200 are arranged at intervals, thus forming the second material distribution channel 210. The distance between the first material distribution channel 110 and the second material distribution channel 210 gradually increases, so that when the flexible catheter of the venous needle gradually passes through the feeding device, the flexible catheter can be gradually smoothed out.

[0041] Furthermore, the venous needle feeding device further includes a mounting plate 300. The mounting plate 300 is arranged along the arrangement direction of the first material channel members 100, and all the first material channel members 100 are connected to the bottom of the mounting plate 300.

[0042] Specifically, the mounting plate 300 is integrally in a "U" - shaped flat plate shape and is arranged along the arrangement direction of the first material channel members 100. The first material channel members 100 are sequentially bolt - connected to the mounting plate 300 through "L" - shaped folding plates. The mounting plate 300 is connected to the linear vibrator 20. Thus, by fixing all the first material channel members 100 on the mounting plate 300 connected to the linear vibrator 20, all the first material channel members 100 can be vibrated synchronously, ensuring the feeding stability of the feeding device.

[0043] Preferably, the venous needle feeding device is provided with two linear vibrators 20. The two linear vibrators 20 are respectively arranged on both sides of the material distribution mechanism 10, and the linear vibrators 20 are connected to both ends of the mounting plate 300.

[0044] Specifically, the two linear vibrators 20 are respectively fixed on the platform of the production line by bolts. The two linear vibrators 20 are respectively arranged on both sides of the material distribution mechanism 10, and the vibrating ends of the linear vibrators 20 are connected to the mounting plate 300 by bolts. Thus, the two linear vibrators 20 can vibrate simultaneously at both ends of the mounting plate 300, so that both sides of the mounting plate 300 vibrate synchronously, and further ensure the stability of the first material channel member 100 during vibration.

[0045] Furthermore, the first material channel member 100 includes a feeding section 120, a connecting section 130, and a discharging section 140; the feeding section 120, the connecting section 130, and the discharging section 140 are connected in sequence. The bottom of the feeding section 120 is connected to the second material channel member 200, and the top of the connecting section 130 is connected to the mounting plate 300.

[0046] Specifically, the feeding section 120, the connecting section 130, and the discharging section 140 are integrally formed. The bottom of the entrance of the feeding section 120 is bolted to the second material channel member 200, or the bottom of the entrance of the feeding section 120 abuts against the entrance of the second material channel member 200. The top of the connecting section is bolted to the mounting plate 300. Thus, the entrances of the first material distribution channel 110 and the second material distribution channel 210 can be arranged together, so that the material can easily enter the first material distribution channel 110 and the second material distribution channel 210 from their entrances.

[0047] Preferably, the feeding section 120 is arc-shaped, and one end thereof away from the connecting section 130 is higher than the end close to the connecting section 130.

[0048] Specifically, the feeding section 120 is arc-shaped, and one end of its entrance is higher than the end close to the connecting section 130. Thus, the height of the feeding section 120 shows a gradually decreasing trend, so that the self-weight of the intravenous needle, in cooperation with the linear vibrator 20, makes the intravenous needle move forward gradually to improve the feeding efficiency.

[0049] Furthermore, two relatively arranged channel plates 121 are provided on the feeding section 120. The two channel plates 121 are spaced apart to enclose and form the first material distribution channel 110, and the distance between the two channel plates 121 gradually increases in the vertically upward direction.

[0050] Specifically, the cross-sections of the two channel plates 121 in the vertical direction are arranged in a "V" shape, and the two channel plates 121 are spaced apart. Thus, an opening groove is formed at the bottom of the two channel plates 121. The width of the opening groove is slightly larger than the diameter of the flexible catheter of the intravenous needle and slightly smaller than the diameter of the tip of the intravenous needle. Thus, the first material distribution channel 110 can be formed by the cooperation of the two channel plates 121 to facilitate the entry of the intravenous needle into the material distribution channel and prevent it from shifting and jamming.

[0051] Furthermore, a protective shell 141 is provided on the top of the discharging section 140. The first material distribution channel 110 is arranged at the bottom of the discharging section 140, and an observation hole 142 is provided on the top of the discharging section 140.

[0052] Specifically, the protective case 141 is a square case as a whole and covers the top of the discharging section 140. The observation hole 142 is a long waist-shaped hole and is arranged directly above the first material distribution channel 110. Thus, the arrangement state of the intravenous needles arranged in the first material distribution channel 110 can be observed through the observation hole 142, so that the operator can adjust the material state in a timely manner.

[0053] Furthermore, a material pushing block 220 is arranged at the bottom of the second channel member 200, and the material pushing block 220 is arranged at one end of the second channel member 200 away from the first channel member 100.

[0054] Specifically, the material pushing block 220 is arranged in a frustum shape at the bottom of the second channel member 200 and is located on the bottom surface of the second channel member 200. When the infusion needle passes through the material pushing block 220, its needle tip will contact the material pushing block 220, so that the infusion needle rotates accordingly to ensure that the orientations of the infusion needles are the same.

[0055] Furthermore, the material distribution mechanism 10 further includes a connecting member 400. One end of the connecting member 400 is connected to the first channel member 100, and the other end of the connecting member 400 is connected to the second channel member 200.

[0056] Specifically, the connecting member 400 is set as a metal flat plate and is in a long strip shape as a whole. In this embodiment, two connecting members 400 are arranged between each first channel member 100 and the second channel member 200 below it, and the two connecting members 400 are arranged with one long and one short. The top of the connecting member 400 is connected to the first channel member 100 by bolts, and the bottom of the connecting member 400 is connected to the second channel member 200 by bolts. Thus, the first channel member 100 and the second channel member 200 can be connected at an angle, so that when the linear vibrator 20 drives the first channel member 100 to vibrate, the second channel member 200 can vibrate synchronously with the first channel member 100 to ensure that the horizontal movement speeds of the upper and lower ends of the intravenous needles are the same and prevent the intravenous needles from jamming.

[0057] The present utility model also provides an infusion set production line, including the above-mentioned intravenous needle feeding device. Since it includes all the structures of the above-mentioned intravenous needle feeding device, it naturally includes all the technical effects of the above-mentioned intravenous needle feeding device, which will not be elaborated here.

[0058] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
