Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to an infusion set separation device. Background Art

[0002] Medical waste needs to be processed in a classified manner, and for disposable infusion sets, the needles need to be separated from the rest of the plastic parts. The traditional method is: most medical staff often use their right hand to take the infusion set needle and switch it to their left hand, and hold the hose of the infusion set to keep the needle suspended in the air, and then use scissors in their right hand to cut off the needle. Needlestick injuries are prone to occur in the above process, and the efficiency is low. Therefore, as disclosed in patent CN114393004A, a batch separation device for infusion set needles is used to pre-treat the infusion set, and the needle is fixed by magnetic suction and then separated from the infusion tube. Considering that the needle is small in size and has a poor magnetic suction effect, the infusion set must be pre-treated first to obtain a large number of needles with shorter infusion tubes. The disadvantage is that the pre-treatment of the infusion set wastes a lot of time. Summary of the invention

[0057] See also Figures 1 to 6 The present embodiment provides an infusion set separation device, including a mounting seat 10, a first guide comb 20, a second guide comb 30, a driving device 40, a clamping mechanism 50 and a separation mechanism 60.

[0058] The first guide comb 20 is arranged on the mounting seat 10, and has a plurality of first guide teeth 21 arranged in parallel with each other, and a first guide opening 22 is formed between two adjacent first guide teeth 21. The second guide comb 30 is movably arranged on the mounting seat 10, and can overlap with the first guide comb 20, and has a plurality of second guide teeth 31 arranged in parallel with each other, and a second guide opening 32 is formed between two adjacent second guide teeth 31. The driving device 40 can drive the second guide comb 30 to move. The clamping mechanism 50 is arranged on the second guide comb 30, and can apply friction to the infusion hose in the second guide opening 32. The separation mechanism 60 can disconnect the infusion hose. The first guide teeth 21 can limit the side wings 71 on the needle 70.

[0059] In this embodiment, the needle 70 of the infusion set has a wing 71 for stabbing, and the needle 70 is connected to the infusion set hose. After the first guide comb 20 and the second guide comb 30 overlap, and the first guide opening 22 and the second guide opening 32 overlap, the infusion set hose is placed in the first guide opening 22 and the second guide opening 32, at which time the wing 71 on the needle 70 is located below the first guide tooth 21. Once the infusion set hose is pulled upward to drive the needle 70 to move upward, the wing 71 on the needle 70 abuts against the first guide tooth 21, and the infusion set hose on the upper side of the first guide comb 20 can be cut off by the separation mechanism 60, thereby separating the infusion set needle 70 from the infusion set hose. During the movement of the second guide comb 30, the clamping mechanism 50 applies a certain friction force to the infusion hose on the second guide comb 30, so that the infusion hose can move with the second guide comb 30, that is, the second guide comb 30 drives the infusion hose to move, thereby driving the needle 70 of the infusion to move close to the first guide tooth 21 of the first guide comb 20, ensuring that when the separation mechanism 60 disconnects the infusion hose, the hose attached to the infusion needle 70 is as short as possible. When the medical staff operates, they can place multiple infusion hoses in different first guide ports 22 and second guide ports 32 respectively, and separate the needles 70 of multiple infusions at the same time, which improves efficiency and saves time. When the device is operated, the medical staff's hands are kept away from the infusion needle 70, which can reduce the probability of being stabbed.

[0060] In one embodiment, the first guide comb 20 includes a first comb spine 23 fixedly connected to the mounting seat 10, a plurality of first guide teeth 21 are connected to one end of the first comb spine 23 away from the mounting seat 10, two parallel guide rings 72 are rotatably provided on the mounting seat 10, the second guide comb 30 includes a second comb spine 33, both ends of the second comb spine 33 are respectively connected to the guide ring 72 on the same side, a plurality of second guide teeth 31 are connected to one end of the second comb spine 33 away from the guide ring 72, and the driving device 40 is used to drive the guide ring 72 to rotate on a fixed axis. Specifically, two arc grooves are provided on the mounting seat 10, and the two guide rings 72 slide in the arc grooves on their respective sides.

[0061] In this embodiment, the second guide comb 30 is driven by the guide ring 72 to rotate away from the first guide comb 20. At the same time, the second guide comb 30 pulls the infusion hose, thereby pulling the needle 70 of the infusion set upward to abut against the first guide comb 20. Since the trajectory of the second guide comb 30 is circular, the infusion hose placed in the second guide opening 32 will not have a large fluctuation during the movement of the second guide comb 30. The infusion hose has a small movement amplitude during the operation of the device, and the design is relatively reasonable.

[0062] In one embodiment, a downwardly penetrating hole 311 is formed on the second guide tooth 31, and a penetrating clamping hole 312 is formed on one side of the second guide tooth 31 facing the adjacent second guide tooth 31;

[0063] Specifically, since the second guide teeth 31 in the middle have second guide teeth 31 on both sides, it means that clamping holes 312 need to be opened on both sides of the second guide teeth 31 , while the second guide teeth 31 at the edge only need to have one clamping hole 312 .

[0064] The clamping mechanism 50 comprises:

[0065] There are multiple arc-shaped trigger blocks 51, one end of which is connected to the upper end surface of the first guide tooth 21, and the other end passes through the corresponding clearance hole 311, and the lateral dimension from one end to the other end gradually increases;

[0066] The limiting plate 52 is located in the clearance hole 311, one is provided for each clamping hole 312, and can slide close to or away from the clamping hole 312, and the end thereof away from the clamping hole 312 can contact the side of the arc-shaped trigger block 51; and

[0067] Specifically, in addition to the opening of the clamping hole 312, the inner wall of the clearance hole 311 also has several guide holes, and the limiting plate 52 is provided with a plurality of guide pins, which are slidably matched with the guide holes, so that the limiting plate 52 can slide closer to or away from the clamping hole 312. In addition, a spring (not shown) is sleeved on the guide pin.

[0068] A clamping airbag 53 is provided corresponding to each limiting plate 52 and is located in the clamping hole 312. Its end is connected to the limiting plate 52. Its end away from the limiting plate 52 can extend from the clamping hole 312 into the corresponding second guide port 32 to contact the infusion hose.

[0069] Specifically, the overall shape of the clamping airbag 53 matches the shape of the clamping hole 312 and is generally in the shape of a rectangular parallelepiped. Correspondingly, the clamping hole 312 is also a long hole.

[0070] In this embodiment, under the drive of the driving device 40, the guide ring 72 drives the second guide comb 30 to rotate, the second guide comb 30 moves away from the first guide comb 20, and the second guide comb 30 moves along the length direction of the arc-shaped trigger block 51. The size of the arc-shaped trigger block 51 changes (gradually increases), and the limit plate 52 in the position hole 311 is squeezed, so that the limit plate 52 drives the clamping airbag 53 to move toward the second guide port 32, so that the clamping airbag 53 is used to clamp the infusion hose in the second guide port 32. The clamping airbag 53 does not clamp the infusion hose very hard, and can only pull the infusion hose to move until the side wings 71 on the needle 70 of the infusion hose contact and abut against the bottom of the first guide comb 20 and cannot move further. The infusion hose of the same infusion hose will also slip at the clamping airbag.

[0071] In one embodiment, one end of the first guide tooth 21 away from the first comb spine 23 is lower than the other end thereof, and a placement hole 211 penetrating in the transverse direction is further provided on the first guide tooth 21, the placement hole 211 is communicated with the side wall of the first guide opening 22, and each first guide opening 22 has a placement hole 211 on both sides, and each first guide opening 22 is provided with a limiting mechanism 80;

[0072] The limiting mechanism 80 includes two guide rails 81, two sliders 82 and a connecting rope 83, and can be in contact with the needle 70 of the infusion set.

[0073] The two guide rails 81 are symmetrically arranged in two adjacent placement holes 211, and are arranged obliquely along the length direction of the first guide opening 22, with one end of the guide rails 81 close to the first comb ridge 23 being biased toward the first guide opening 22. Two sliders 82 are slidably arranged on the corresponding guide rails 81, and one end of the slider 82 can slide into the first guide opening 22. The connecting rope 83 spans the first guide opening 22, and the two ends are respectively connected to the sliders 82 on both sides, and can contact the needle 70 of the infusion set.

[0074] In this embodiment, the first guide comb 20 is arranged obliquely. In a natural state, the two sliders 82 slide along the guide rail 81 under their own weight and move away from the first guide port 22. When the slider 82 slides along the guide rail 81 and approaches the first comb spine 23, the ends of the two sliders 82 slide into the first guide port 22. As shown in Figure *, when in use, the needle 70 of the infusion set is placed below the first guide port 22. When the infusion set hose is pulled to the upper right, the infusion set needle 70 contacts the connecting rope 83 and drives the two sliders 82 to approach the first comb spine 23. At the same time, the two sliders 82 approach each other. The side wings 71 on the infusion set needle 70 are usually limited by the first guide teeth 21, and in a few cases, they are limited by the two sliders 82, so that the needle 70 is below the first guide teeth 21.

[0075] In one embodiment, the driving device 40 includes a motor 41 and a connecting rod 42 .

[0076] The motor 41 is disposed on the mounting seat 10 . A plurality of connecting rods 42 are provided, one end of each of the connecting rods 42 is connected to the guide ring 72 , and the other end of each of the connecting rods 42 is connected to the rotating shaft of the motor 41 .

[0077] In one embodiment, a shielding plate 73 is further included, and two ends of the shielding plate 73 are respectively connected to the guide rings 72 on both sides;

[0078] The separation mechanism 60 includes two support rods 61 and a thermal fuse 62 .

[0079] The lower end of the support rod 61 is connected to the mounting base 10. Both ends of the thermal fuse 62 are respectively connected to the support rod 61. Specifically, the thermal fuse 62 is externally connected to a PLC controller (not shown) and a power source (not shown) for power supply.

[0080] When the second guide comb 30 overlaps with the first guide comb 20, the shielding plate 73 is located between the second guide comb 30 and the thermal fuse 62; when the second guide comb 30 rotates away from the first guide comb 20, the thermal fuse 62 can contact the infusion hose and complete the cutting.

[0081] In this embodiment, the hot fuse 62 is shielded by the shielding plate 73 when not cutting, and the infusion set is placed on the second guide comb 30 and the shielding plate. When the second guide comb 30 is away from the first guide comb 20, the infusion set hose is pulled, and the needle 70 of the infusion set is against the first guide comb 20. As the second guide comb 30 further rotates, the infusion set hose between the second guide comb 30 and the first guide comb 20 will contact the hot fuse 62, thereby being melted. The infusion set needle 70 falls naturally, and then the remaining parts of the separated infusion set are manually packed in a bag.

[0082] In one embodiment, the mounting base 10 is further provided with an electromagnetic member 90, which is located below the first comb ridge 23 and corresponds to the plurality of first guide ports 22. The electromagnetic member 90 is externally connected to a power source (not shown) and a PLC controller (not shown), and generates magnetism when powered on. When the needle 70 of the infusion set is placed below the first guide port 22, it is adsorbed by the electromagnetic member 90, so that when the infusion set hose is pulled, the needle 70 of the infusion set is kept below the first comb ridge 23, that is, once the needle 70 of the infusion set is placed below the first guide port 22, the limiting mechanism 80 can be triggered to prevent it from being separated from the first guide comb 20.

[0083] In addition, a transition guide plate 74 is also provided on the second guide tooth 31, the lower end of the transition guide plate 74 is connected to the edge of the second guide port 32, and the upper end of the transition guide plate 74 is close to the arc-shaped guide block, so that the infusion pump can be placed in the first guide port 22 and the second guide port 32 more smoothly.

However, it is understood that embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
