Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a novel device for removing post-needle patches. Background Technology

[0002] As a medical wound care product, post-needle dressings are used in clinical practice to seal tiny needle puncture sites from procedures such as intravenous infusions, intramuscular injections, and blood collection. Post-needle dressings can replace traditional cotton balls and swabs, and can more effectively reduce the risk of iatrogenic infections, thus helping to reduce the environmental threat posed by medical waste. The post-needle dressing consists of a medical-grade substrate layer, a medical-grade hot-melt pressure-sensitive adhesive layer, an absorbent pad, and release paper. For post-needle dressing rolls, multiple dressings are sequentially adhered to the surface of the release paper strip. When needed, the roll is unwound, and medical personnel take the dressings sequentially from the release paper strip.

[0003] Among them, the Chinese utility model patent with patent number ZL202122198945.7 and patent name: Automatic Post-Needle Adhesive Retrieval Device, substantially discloses an automatic post-needle adhesive retrieval device; specifically, the automatic post-needle adhesive retrieval device includes a housing, a post-needle adhesive retrieval port on the housing, a post-needle adhesive placement device inside the housing located on one side of the post-needle adhesive retrieval port, a waste tape recycling device inside the housing located below the post-needle adhesive retrieval port, a photoelectric sensor on one side of the post-needle adhesive retrieval port, and a PCB control board electrically connected to the photoelectric sensor inside the housing; the waste tape recycling device includes a drive gear, a pinion, and a large gear, the drive gear is powered by a motor, the drive gear meshes with both the pinion and the large gear, the centers of the pinion and the large gear are on the same horizontal line, a recycling guide shaft extends from the pinion, a bearing is provided between the pinion and the recycling guide shaft, and a pressure plate device is provided at the extended end of the recycling guide shaft, and a waste tape recycling wheel meshes with the large gear.

[0004] When the above-mentioned fully automatic needle-attachment pick-up device is working, the needle-attachment roll is first placed on the needle-attachment placement device. One end of the needle-attachment roll is pulled out from below the needle-attachment roll and passes over the needle-attachment guide post from above the needle-attachment pick-up port to below the needle-attachment pick-up port. The needle-attachment is peeled off from the waste tape. The waste tape is then passed between the recycling guide shaft and the pressure plate device and wound onto the waste tape recycling wheel to recycle the waste tape.

[0005] It should be noted that the aforementioned fully automatic post-needle adhesive patch removal device has the following drawbacks, specifically:

[0006] Defect 1: The waste tape recycling device includes a drive gear, a pinion, and a large gear. The drive gear is connected to the motor and meshes with both the pinion and the large gear. A recycling guide shaft extends from the pinion, and a bearing is provided between the pinion and the recycling guide shaft. A pressure plate device is provided at the extended end of the recycling guide shaft. A waste tape recycling wheel meshes with the large gear. The entire waste tape recycling device has a complex structure and will increase the structural complexity of the entire fully automatic needle-attachment device.

[0007] Defect 2: When using this fully automatic post-application device, the end of the waste tape needs to be fastened to the waste tape recovery wheel to ensure that the waste tape recovery wheel can wind up the waste tape. Furthermore, since the waste tape roll wound on the waste tape recovery wheel will hug the wheel tightly, it is also inconvenient to remove the waste tape roll from the waste tape roll. Therefore, this fully automatic post-application device has the defect of being inconvenient to use. Utility Model Content

Detailed Implementation

[0034] The present invention will now be described in conjunction with specific embodiments.

[0035] Example 1, as Figure 1 and Figure 4 As shown, a novel needle-attachment dispensing device includes a main box 1 and a roll material hanging rod 2 installed on the main box 1 for hanging needle-attachment roll material 8. The main box 1 has an internal cavity with an opening to the left or right.

[0036] like Figures 1 to 5 As shown, the main box body 1 is hinged with a lid 3 located on the opening side of the inner cavity of the box body. The main box body 1 is provided with a horizontal partition 11 and a vertical partition 12 located in the inner cavity of the box body. The vertical partition 12 is located below the horizontal partition 11. The space in the inner cavity of the box body above the horizontal partition 11 is a roll material placement cavity 13, and the roll material hanging rod 2 is located in the roll material placement cavity 13. The vertical partition 12 divides the space in the inner cavity of the box body below the horizontal partition 11 into a driving cavity 14 and a paper tape collection cavity 15 located behind the driving cavity 14. It should be noted that the horizontal partition 11, the vertical partition 12, and the main box body 1 are an integral structure.

[0037] Furthermore, such as Figures 1 to 5 As shown, the front end of the transverse partition 11 protrudes forward from the front surface of the main box 1. The front surface of the main box 1 has an upper opening 16 located above the transverse partition 11 and communicating with the roll material placement cavity 13, and a lower opening 17 located below the transverse partition 11 and communicating with the drive cavity 14.

[0038] Furthermore, such as Figure 1 , Figure 3 as well as Figure 4 As shown, the drive cavity 14 is equipped with a paper tape traction roller group, which includes an active traction roller 41 and a driven traction roller 42 that are rotatably mounted on the main box 1. The active traction roller 41 is driven by a stepper motor (not shown in the figure). A paper tape channel 18 located behind the paper tape traction roller group is opened between the upper end of the vertical partition 12 and the horizontal partition 11.

[0039] For the paper tape traction assembly 4 in this embodiment, the release paper tape 82 of the needle-attach roll 8 is connected between the active traction roller 41 and the driven traction roller 42. The stepper motor steps and drives the active traction roller 41 to rotate step by step. The active traction roller 41 and the driven traction roller 42 cooperate to pull the release paper tape 82 toward the paper tape collection cavity 15. The paper tape traction assembly 4, composed of the stepper motor, the active traction roller 41 and the driven traction roller 42, can realize the fixed-length delivery of the release paper tape 82 to ensure that only the needle-attach 81 moves to the picking position during each picking operation by medical staff.

[0040] In the process of using the novel post-needle adhesive dispensing device of this embodiment to dispensing the post-needle adhesive 81, the box cover 3 is first opened and the post-needle adhesive roll 8 is hung on the roll hanging rod 2. Then, the end of the post-needle adhesive roll 8 is pulled out and the centrifugal paper tape of the post-needle adhesive roll 8 passes sequentially through the upper opening 16, the lower opening 17, and between the active traction roller 41 and the driven traction roller 42. Then, the box cover 3 is closed. When dispensing, the stepper motor drives the active traction roller 41 to rotate step by step, and the traction drive assembly pulls the release paper tape 82 and makes the post-needle adhesive 81 on the post-needle adhesive roll 8... 1. The paper tape 82 is sequentially transferred to the front end of the transverse partition 11. Since the release paper tape 82 turns and bends at the front end of the transverse partition 11, the needle backing tape 81 pasted on the release paper tape 82 will automatically flip over to facilitate medical staff to take it. As the paper tape traction component 4 continuously pulls the centrifugal paper tape toward the paper tape collection chamber 15, the centrifugal paper tape is sent into the paper tape collection chamber 15 of the main box 1. When the needle backing tape roll 8 is used up, the box cover 3 is opened and a new needle backing tape roll 8 is hung on the roll hanging rod 2, and the centrifugal paper tape in the paper tape collection chamber 15 is taken away.

[0041] It should be emphasized that the novel needle-attachment picking device in this embodiment uses a paper tape traction assembly 4, which consists of a stepper motor, an active traction roller 41, and a driven traction roller 42, to pull the centrifugal paper tape. The centrifugal paper tape is directly fed into the paper tape collection chamber 15 of the main box 1 through the paper tape traction assembly 4, so as to collect the centrifugal paper tape through the paper tape collection chamber 15. Compared with the waste tape recycling device in the prior art, the centrifugal paper tape collection device in this embodiment has a simpler structure and is more convenient to operate and use.

[0042] In summary, the novel needle patch dispensing device of this embodiment has the advantages of novel design, simple structure, and convenient use through the above structural design.

[0043] Example 2, as Figure 2 and Figure 3 As shown, the difference between this embodiment 2 and embodiment 1 is that: a control box 5 is provided on the opposite side of the box cover 3 of the main box body 1, a stepper motor is installed inside the control box 5, and the power output shaft of the stepper motor is connected to the active traction roller 41.

[0044] The control box 5 is equipped with a PCB circuit board (not shown in the figure), and the front surface of the main box 1 is equipped with a push switch 6. The stepper motor and the push switch 6 are electrically connected to the PCB circuit board.

[0045] When using the novel needle patch dispensing device in this embodiment 2, medical staff press the press switch 6 on the front surface of the main box 1 to control the stepper motor to start and move step by step, thereby causing the paper tape traction component 4 to move and pull the subsequent needle patch 81 to the front end of the transverse partition 11; when medical staff need to drive the needle patch 81 again, they need to press the press switch 6 again.

[0046] Example 3 differs from Example 2 in that the control box 5 is also equipped with a power supply battery (not shown in the figure), which is electrically connected to the PCB circuit board.

[0047] Specifically, the power supply battery is a rechargeable battery, and the front surface of the main box 1 is also equipped with a charging interface (not shown in the figure), which is electrically connected to the PCB circuit board.

[0048] This embodiment three uses a rechargeable battery for power supply; when the rechargeable battery is low on power, it can be charged through the charging interface to improve ease of use.

[0049] Example 4, as Figures 1 to 3 As shown, the difference between this embodiment four and embodiment one is that: the main box body 1 has a vertically extending elongated hole 19 corresponding to the coil hanging rod 2, and the end of the coil hanging rod 2 is slidably installed in the elongated hole 19.

[0050] When the needle-attached roll 8 is hung on the roll hanging rod 2, the roll hanging rod 2 will move downward along the elongated hole 19 due to the weight of the needle-attached roll 8, and the needle-attached roll 8 will automatically abut against the upper surface of the transverse partition 11 to ensure that the needle-attached roll 8 can be fed forward horizontally along the transverse partition 11.

[0051] Example 5, as Figure 1 , Figure 3 as well as Figure 4 As shown, the difference between this fifth embodiment and the first embodiment is that an auxiliary pressure roller 7 is installed in the front side of the coil hanging rod 2 in the coil placement cavity 13, and the auxiliary pressure roller 7 is rotatably installed on the main box body 1.

[0052] The auxiliary pressure roller 7 and the transverse partition 11 are arranged at intervals, and there is a material passage gap between the auxiliary pressure roller 7 and the transverse partition 11.

[0053] When the post-needle adhesive roll 8 passes through the material feed gap, the auxiliary pressure roller 7 applies a certain pressure to the post-needle adhesive roll 8. This pressure causes friction between the post-needle adhesive roll 8 and the transverse partition 11. This friction causes the release paper tape 82 passing through the front end of the transverse partition 11 to remain taut, thereby improving the stability of the post-needle adhesive roll 81 when it is fed out.

[0054] Example 6, as Figures 1 to 5 As shown, the difference between this sixth embodiment and the first embodiment is that the front edge of the transverse partition 11 is provided with a positioning groove 111 for the release paper tape 82 to pass through.

[0055] When the release paper tape 82 passes through the positioning groove 111 at the front edge of the transverse partition 11, the transverse partition 11 uses the positioning groove 111 to perform transverse positioning of the release paper tape, so as to avoid the release paper tape 82 from deviating during traction movement.

[0056] Example 7, as Figure 1 , Figure 3 as well as Figure 4 As shown, the difference between this embodiment seven and embodiment one is that the upper end of the vertical partition 12 is provided with a paper tape guide 121 in an arc-shaped bending shape.

[0057] As for the paper tape guide 121 in this embodiment, it can accurately guide the centrifugal paper tape delivered by the paper tape traction assembly 4 into the paper tape collection cavity 15 of the main box 1.

[0058] Example 8: The difference between Example 8 and Example 1 is that the lid 3 is a transparent part.

[0059] When using the novel post-needle patch dispensing device in this embodiment eight, medical staff can observe the remaining amount of post-needle patch roll 8 and the collection status of release paper tape 82 in the paper tape collection chamber 15 through the transparent box cover 3.

[0060] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
