Description

Technical Field

[0001] This invention relates to the field of syringe manufacturing equipment technology, and more specifically to a syringe needle tip orientation device. Background Technology

[0002] Skin testing, short for skin (or intradermal) sensitivity test, is the most commonly used specific examination in clinical practice. Certain medications are prone to causing allergic reactions during clinical use, such as penicillin, streptomycin, and cytochrome C. Common allergic reactions include rash, urticaria, dermatitis, fever, angioedema, asthma, and anaphylactic shock, with anaphylactic shock being the most severe and potentially fatal. To prevent allergic reactions, especially severe ones, skin sensitivity tests are required before using medications that are prone to causing allergic reactions. Skin testing is a live in vivo test, simple to perform, and yields highly reliable results, frequently used in clinical and disease prevention work. The medical devices used for performing skin tests are generally disposable syringes.

[0003] With the widespread use of self-destructing syringes with fixed needles, the impact on skin test procedures is increasing. For example, inconsistencies in needle tip direction and printed graduations can lead to inconveniences in clinical practice.

[0004] This necessitates orienting the needle tip of a self-destructing syringe with a fixed needle so that it aligns with the direction of the scale, allowing medical personnel to clearly read the scale when adjusting the needle tip to the appropriate angle. However, there is currently no device capable of orienting the syringe needle tip. Summary of the Invention

[0048] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention is further described below.

[0049] See Figures 1 to 8 As shown, a syringe needle tip orientation device includes a frame (not shown), a limiting platform 100, a clamping device 200, a lifting device 300, a needle tip orientation device 400, a curing device 500, and a control device 600. The control device is connected to the clamping device 200, the lifting device 300, the needle tip orientation device 400, and the curing device 500. The control device is a commonly used control device in the prior art and can be a PLC control device.

[0050] The limiting stage 100 is mounted on the machine frame and is used to place the upper needle bar 10. The limiting stage 100 has a limiting groove 110 in the middle, and the upper needle bar 10 can be fixed in the limiting groove 110.

[0051] A clamping device 200 is mounted on the frame and is used to clamp the outer sleeve assembly 20 radially. In this embodiment, the clamping device 200 includes a first horizontal drive device 210 and a clamping block 220 connected to the drive end 211 of the first horizontal drive device 210. The first horizontal drive device 210 can be a cylinder. The clamping block 220 has an arc-shaped groove 221 on its working surface facing the outer sleeve assembly 20 that matches the outer contour of the outer sleeve assembly 20. When the first horizontal drive device 210 is working, it drives the clamping block 220 to clamp closer to the outer sleeve assembly 20. The outer sleeve assembly 20 is radially restricted in the arc-shaped groove 221 of the clamping block 220 and the positioning block 1, but the outer sleeve assembly 20 can move vertically at this time.

[0052] A lifting device 300 is mounted on the frame and is used to lift the outer sleeve assembly 20 along its axial direction. In this embodiment, the lifting device 300 includes a second horizontal drive device 310 and a vertical drive device 320 connected to the drive end 311 of the second horizontal drive device 310. A clamping arm 330 is connected to the drive end 321 of the vertical drive device 320. The second horizontal drive device 310 and the vertical drive device 320 can be cylinders. When the second horizontal drive device 310 is working, it drives the vertical drive device 320 to move towards the outer sleeve assembly 20, which in turn drives the clamping arm 330 to move towards the outer sleeve assembly 20. When the clamping arm 330 reaches the outer surface of the outer sleeve assembly 20, it clamps the outer sleeve assembly 20. At this time, the vertical drive device 320 can drive the outer sleeve assembly 20 to move vertically. To ensure that the lifting device 300 is lifted into place, a limiting step 2 corresponding to the lifting device 300 is provided on the frame. When the outer periphery 21 of the tail of the outer casing 20 touches the limiting step 2, it can no longer move upward.

[0053] A needle tip orientation device 400 is mounted on the frame and is used to orient the needle tip 23 of the needle tube 22 on the outer casing assembly 20. Combined with... Figures 9 to 22As shown, in this embodiment, the needle tip orientation device 400 includes a reference block 410 and a rubbing block 420. The reference block 410 is connected to a first moving device (not shown in the figure), which can be a cylinder. The first moving device is used to move the reference block 410 to a designated position and fix it during operation. The rubbing block 420 is connected to an elastic sheet 430, which is connected to a reciprocating motion drive device (not shown in the figure). The reciprocating motion drive device can be a linear motor, which is used to drive the elastic sheet 430 to reciprocate, so that the rubbing block 420 has a reciprocating rubbing action on the needle tube 22. The reciprocating motion drive device is connected to a second moving device (not shown in the figure), which can be a cylinder. The second moving device is used to move the reciprocating motion drive device to a designated position and fix it during operation. The side 411 of the reference block 410 facing the needle tube 22 has a calibration inclined surface 412 corresponding to the needle tip 23 of the needle tube 22, and the side of the rubbing block 420 facing the needle tube 22 is a working surface 421. To increase the friction between the working surface 421 and the needle tube 22 and prevent the working surface 421 from slipping, a friction layer is provided on the working surface 421.

[0054] The curing device 500 is mounted on the frame and is used to cure the oriented needle tube 22 with adhesive. In this embodiment, the curing device 500 includes an adhesive spraying device 510 and a curing lamp 520.

[0055] The working principle of this invention is as follows:

[0056] The upper needle bar 10 is fixed in the limiting groove 110. The tail of the outer sleeve assembly 20 to be oriented is inserted into the positioning head 11 of the upper needle bar 10. The top of the outer sleeve assembly 20 has a needle tube 22. At this time, the needle tube 22 is not completely fixed to the top of the outer sleeve assembly 20, and the direction of the needle tip 23 of the needle tube 22 may not be consistent with the scale 24 of the outer sleeve assembly 20 (e.g., Figure 2 (As shown).

[0057] When the first horizontal drive device 210 operates, it drives the clamping block 220 to clamp close to the outer sleeve assembly 20. The outer sleeve assembly 20 is radially confined within the arcuate groove 221 of the clamping block 220 and the positioning block 1, but at this time, the outer sleeve assembly 20 can move vertically. Simultaneously, the second horizontal drive device 310 operates, driving the vertical drive device 320 to move towards the outer sleeve assembly 20, thereby driving the clamping arm 330 to move towards the outer sleeve assembly 20. When the clamping arm 330 reaches the outer surface of the outer sleeve assembly 20, the clamping arm 330 clamps the outer sleeve assembly 20, and at this time, the vertical drive device 320 can drive the outer sleeve assembly 20 to move vertically (e.g., ...). Figure 3 (As shown).

[0058] The vertical drive device 320 operates to raise the clamping arm 330 until the outer periphery 21 of the tail of the outer casing assembly 20 touches the limiting step 2, at which point it can no longer move upwards. This is to perform height positioning of the outer casing assembly 20 and eliminate height errors (such as...). Figure 4 (As shown).

[0059] The needle tip orientation device 400 is used to orient the needle tip 23 of the needle tube 22 on the outer casing assembly 20. Combined with... Figures 9 to 22 As shown, when the needle 22 of the outer sleeve assembly 20 rises to a designated height, the reference block 410 and the rubbing block 420 are located on both sides of the needle 22. Then, the first moving device drives the reference block 410 to move, so that one side 411 of the reference block 410 contacts the outer wall of the needle 22; at this time, the reference block 410 remains stationary. The second moving device then drives the reciprocating motion drive device to move to a designated position. Since the reciprocating motion drive device is connected to the elastic plate 430, the rubbing block 420 also reaches the designated position. At this time, the working surface 421 of the rubbing block 420 slightly presses against the outer wall of the needle 22, and the elastic plate 430 applies elastic force to the rubbing block 420, so the needle 22 is clamped by the rubbing block 420 and the reference block 410 (e.g., ...). Figure 13 and Figure 14 (As shown). Then the reciprocating motion drive device drives the elastic plate 430 to reciprocate several times (as shown). Figure 15 and Figure 16 As shown, the direction of reciprocating motion is as follows Figure 16 (As shown by the black arrow in the image), at this time, the rubbing block 420 will also rub the syringe 22 back and forth several times. When the needle tip 23 of the syringe 22 is rubbed to the calibration slope 412, under the action of the elastic plate 430 and the elasticity of the syringe 23 itself, the syringe 23 will bend slightly. At this time, the needle tip 23 of the syringe 22 will be pressed against the calibration slope 412, and the direction of the needle tip 23 of the syringe 22 will be corrected to be consistent with the angle of the calibration slope 412. Moreover, because the needle tip 23 and the calibration slope 412 mutually limit each other, when the syringe 22 is rubbed again, the needle tip 23 of the syringe 22 will not leave the calibration slope 412 (as shown by the black arrow in the image). Figure 17 and Figure 18 (As shown). Therefore, after the reciprocating motion drive stops working, the direction of the needle tip 23 of the needle tube 22 has been adjusted. During operation, it is only necessary to set the direction of the calibration ramp 412 to be consistent with the direction of the scale 24 on the outer casing assembly 20. After the reciprocating motion drive stops working, the reference block 410 and the rubbing block 420 can be reset (as shown). Figures 19 to 22 (As shown).

[0060] After the needle tip 23 of the needle tube 22 on the outer casing assembly 20 is oriented, glue is sprayed using the glue spraying device 510 to fix the top of the outer casing assembly 20 to the bottom of the needle tube 22, and then cured using the curing lamp 520 (e.g., Figure 6 (As shown).

[0061] After the needle 22 has cured, the clamping device 200, lifting device 300, needle tip orientation device 400, and curing device 500 are reset (e.g., Figure 7 (As shown).

[0062] Finally, the outer jacket assembly 20, along with the upper needle strip 10, is removed after orientation is completed, and each device enters the next cycle of operation (e.g., ...). Figure 8 (As shown).

[0063] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
