The embodiment of the disclosure relates to a pickup device which is suitable for picking up infusion bags. In the present embodiment, the pickup device may also be referred to as a clamping device, a pickup mechanism, or the like, and the pickup device of the present embodiment can facilitate picking up an infusion bag and obtaining a liquid medicine in the infusion bag by using a syringe after picking up the infusion bag.

Fig. 1A is a schematic diagram illustrating a first perspective of a pickup apparatus 400 in accordance with an example of the present invention; fig. 1B is a schematic diagram illustrating a second viewing angle of the pickup apparatus 400 according to an example of the present invention.

In some examples, the pickup apparatus 400 may include a base 41, a bearing 42, a first clamp 43, and a second clamp 44 (see fig. 1A and 1B). The first clamping portion 43 and the second clamping portion 44 may be provided on the bearing block 42. The first clamping portion 43 and the second clamping portion 44 can cooperate to clamp the infusion bag 200. The bearing block 42 may be rotatably provided on the base 41. In some examples, the supporting base 42 may rotate to turn the infusion bag 200 clamped by the first clamping portion 43 and the second clamping portion 44, so as to turn the infusion bag 200 from the state shown in fig. 1A to a state in which the liquid outlet faces downward. In this case, the liquid medicine in the infusion bag 200 can be located near the liquid outlet of the infusion bag 200 under the action of gravity, so that the needle of the syringe can conveniently obtain the liquid medicine in the infusion bag.

In some examples, the base 41 may be a robotic arm. The base 41 can move in a translational and rotational manner to drive the first clamping portion 43 and the second clamping portion 44 on the supporting seat 42 to move. Thereby, the pick-up device 400 can be moved closer to or further away from the infusion bag 200 by the movement of the base 41.

In some examples, the pick-up device 400 may also include a suction cup 45 (see fig. 1A). The suction cup 45 may be used to suck the main body of the infusion bag 200. In some examples, the suction cup 45 may be adsorbed to the accommodation portion 201 (described later). Accordingly, the infusion bag can be fixed by the suction cup, and the infusion bag 200 can be turned over more stably.

In some examples, the pick-up device 400 may also include a vacuum pump. A vacuum pump may be in communication with suction cup 45. The vacuum pump may be used to draw air between the suction cup 45 and the accommodating part 201 to form a negative pressure between the suction cup 45 and the accommodating part 201. Therefore, the suction cup 45 can more firmly adsorb the infusion bag 200 through the negative pressure, so that the infusion bag 200 can be more stably turned over.

In some examples, the pick-up device 400 may also include a second sensor. The second sensor may be configured to detect whether or not the container portion 201 of the infusion bag 200 held between the first holding portion 43 and the second holding portion 44 is sucked by the suction cup 45. In some examples, the second sensor may be disposed on the support block 42. The second sensor may face the receptacle 201 of the infusion bag 200 held between the first holding portion 43 and the second holding portion 44. In this case, whether the accommodating portion 201 is sucked by the suction cup 45 when the infusion bag 200 is turned over can be detected by the second sensor, so that the situation that the suction cup 45 cannot suck the accommodating portion 201 can be adjusted in time. In some examples, the second sensor may be a distance sensor.

Fig. 2 is a schematic view showing an infusion bag 200 according to an example of the present invention.

In some examples, the infusion bag 200 can have a receptacle 201, a neck 202, and a flange 203 (see fig. 2). The accommodating part 201 may have an accommodating chamber for accommodating the liquid medicine. The neck 202 may have a hollow. The hollow portion may communicate with the accommodation chamber. Thereby, the medical fluid in the housing chamber can be transferred to the outside of the infusion bag 200 through the hollow portion. In some examples, the exit port of the bag 200 may be located at an end of the neck 202 distal from the receptacle 201.

In some examples, the flange 203 may be annular. The flange 203 may be a protrusion formed extending outward from the outer wall of the neck 202.

In some examples, the body of the infusion bag 200 may be made of a flexible material. In other words, the accommodating part 201 may be made of a flexible material.

In some examples, the bag may have multiple necks 202, e.g., 2, 3, or 4. In the embodiment shown in fig. 2 and 3, the number of the neck portions 202 is 2 two, and the neck portions 202 may include a first neck portion 202a and a second neck portion 202b. Likewise, the flange 203 may include a first flange 203a on the first neck 202a and a second flange 203b on the second neck 202b. In some examples, a first neck 202a may be used to inject a drug into the containment chamber for mixing, and a second neck 202b may be used to infuse a fluid from the containment chamber to the patient.

In some examples, the first clamping portion 43 and the second clamping portion 44 may abut against opposite sides of the neck 202 to pick up the infusion bag 200.

Hereinafter, the pickup apparatus 400 according to the present embodiment will be described by taking an example in which the infusion bag 200 has 2 neck portions 202. It should be noted that, for infusion bags 200 having any other number of necks 202, a person skilled in the art can pick up an infusion bag 200 by slightly modifying the pick-up device 400 based on the number of necks 202.

As described above, the pickup apparatus 400 may include the base 41 and the bearing 42 rotatably provided on the base 41 (see fig. 1A and 3). In some examples, the base 41 and the bearing 42 may be rotatably connected. The bearing block 42 is rotatable about a rotation axis L with respect to the base 41. The rotation axis L may be arranged horizontally in some examples.

In some examples, the support block 42 may be flat. The support base 42 may be provided on the base 41 so that a large end surface is orthogonal to the rotation axis L. The first clamping portion 43, the second clamping portion 44, and the suction cup 45 may be disposed at an end surface of the support base 42 opposite to the base 41. This allows the first clamping portion 43, the second clamping portion 44, and the suction pad 45 to be arranged on the support base 42 in a reasonable layout.

In some examples, the pick-up device 400 may include a plurality of suction cups 45, such as 2, 3, or 4. In the embodiment shown in fig. 3, the number of suction cups 45 is 2, and suction cups 45 may include suction cups 45a and suction cups 45b. The suction cups 45a and 45b may be arranged along the length of the bag 200. This makes it possible to more firmly attach the suction cup 45 to the infusion bag 200.

Fig. 4A is a schematic view showing the first clamping portion 43, the second clamping portion 44, the stopper portion 49, and the driving mechanism 46 according to the example of the present invention; fig. 4B is an exploded view of the pickup device 400 illustrating a second perspective according to an example of the present invention.

As described above, the first clamping portion 43 and the second clamping portion 44 can clamp the infusion bag 200 in cooperation. In some examples, the first clamping portion 43 and the second clamping portion 44 may cooperate to clamp the neck 202 of the infusion bag 200.

In some examples, the first clamping portion 43 and the second clamping portion 44 may cooperate to form a clamping space a. The clamping space a may be matched with the neck 202. In other words, the shape and/or size of the clamping space a may match the shape and/or size of the neck 202.

In some examples, the first clamping portion 43 and the second clamping portion 44 may clamp the neck portion 202 in such a manner that the neck portion 202 is at a predetermined angle with the rotation axis L. In some examples, the first clamping portion 43 and the second clamping portion 44 may clamp the neck 202 in a manner such that the neck is orthogonal to the rotation axis L. In this case, the supporting base 42 can facilitate the infusion bag 200 to rotate so that the outlet of the neck 202 faces downward, and thus the medical liquid in the accommodating portion 201 can be accessed conveniently.

As shown in fig. 4A and 4B, in some examples, the first clip portion 43 may include a first clip arm 431 and a second clip portion 432. The second clamp 44 may include a third clamp arm 443 and a fourth clamp arm 444. The first clamping arm 431 may cooperate with the third clamping arm 432 to clamp the first neck 202a. Second gripping arm 432 may cooperate with fourth gripping arm 444 to grip second neck 202b.

As shown in fig. 4A and 4B, in some examples, first clamp 43 may further include a fifth clamp arm 435 and a sixth clamp arm 436. The second clip portion 44 may further include a seventh clip arm 447 and an eighth clip arm 448. Fifth clamping arm 435 may cooperate with seventh clamping arm 447 to clamp first neck 202a. The sixth clamping arm 436 may cooperate with the eighth clamping arm 448 to clamp the second neck 202b.

In some examples, the location where the first and third clamp arms 431, 443 clamp and the location where the fifth and seventh clamp arms 435, 447 clamp may be on opposite sides of the first flange 203a, respectively. In some examples, the location that second and fourth gripping arms 432, 444 grip and the location that sixth and eighth gripping arms 436, 448 grip may be on opposite sides of second flange 203b, respectively. This enables the neck 202 to be clamped more stably.

In some examples, the first clamping portion 43 may further include a first connection portion 437 (see fig. 4B). The first connection part 437 may be used to connect the first holder arm 431, the second holder arm 432, the fifth holder arm 435, and the sixth holder arm 436. In some examples, the first connection portion 437, the first clamp arm 431, the second clamp arm 432, the fifth clamp arm 435, and the sixth clamp arm 436 may be integrally formed to form the first clamp portion 43.

In some examples, the second clamping portion 44 may also include a second connection portion 449 (see fig. 4B). The second connecting portion 449 may be used to connect the third gripper arm 443, the fourth gripper arm 444, the seventh gripper arm 447, and the eighth gripper arm 448. In some examples, second connecting portion 449, third clamp arm 443, fourth clamp arm 444, seventh clamp arm 447, and eighth clamp arm 448 may be integrally formed to form second clamp portion 44.

In some examples, the first connection 437 can have a notch 437a. The second connecting portion 449 may have an indentation 439a. The position of the notch 437a may be matched with the position of the notch 439a so that the first clamping portion 43 and the second clamping portion 44 intersect. In other words, in the manner shown in fig. 4A. Accordingly, the pickup device 400 can pick up the infusion bag 200 more stably by clamping the first and second neck portions 202a and 202b.

In some examples, the pick-up device 400 may further include a stop portion 49 (see fig. 4A and 4B). The stopper may be provided on the support base 42. In some examples, the stop portion 49 may be located between the first and second clip portions 43, 44. In some examples, the stop portion 49 may be used to abut against the neck 202 when the first and second clamping portions 43 and 44 clamp the neck 202. In other words, the first clamping portion 43, the second clamping portion 44, and the limiting portion 49 may cooperate to abut against the neck portion 202 from three directions, respectively. This enables the neck 202 to be held more stably, thereby improving the stability of picking up the infusion bag 200.

In some examples, the limiting portion 49 may include a first limiting portion 491 and a second limiting portion 492 (see fig. 4B). The first stopper 491 may cooperate with the first holding arm 431, the third holding arm 443, the fifth holding arm 435, and the seventh holding arm 447 to hold the first neck 202a. The second stopper 492 may cooperate with the second gripper arm 432, the fourth gripper arm 444, the sixth gripper arm 436, and the eighth gripper arm 448 to grip the second neck 202b.

In some examples, the first clamp arm 431, the third clamp arm 443, the fifth clamp arm 435, and the seventh clamp arm 447 can have grooves that mate with the first neck 202a. The grooves on the first and fifth gripper arms 431 and 435 may be disposed opposite the grooves on the third and seventh gripper arms 443 and 447. In some examples, the first neck 202a may be placed in grooves on the first clamp arm 431, the third clamp arm 443, the fifth clamp arm 435, and the seventh clamp arm 447 while the first and second clamp portions 43, 44 clamp the first neck 202a. This enables the first and second clamping portions 43 and 44 to clamp the first neck portion 202a more stably.

In some examples, second clamp arm 432, fourth clamp arm 444, sixth clamp arm 436, and eighth clamp arm 448 may have grooves that mate with second neck 202b. The grooves on second and sixth gripping arms 432, 436 may be disposed opposite the grooves on fourth and eighth gripping arms 444, 448. In some examples, when the first and second clamping portions 43, 44 clamp the second neck 202b, the second neck 202b can be placed in grooves on the second, fourth, sixth, and eighth clamping arms 432, 444, 436, 448. This enables the first clamping portion 43 and the second clamping portion 44 to clamp the second neck portion 202b more stably.

In some examples, the pick-up device 400 may also include a drive mechanism 46 (see fig. 4A). The driving mechanism 46 may be used to drive the first clamping portion 43 and the second clamping portion 44 to move relatively, so that the first clamping portion 43 and the second clamping portion 44 clamp or release the neck 202.

In some examples, the drive mechanism 46 may include a slide 461, a first slider 462, and a second slider 463. The first and second sliders 462 and 463 may be tongue-and-groove coupled with the slider 461. Thereby, the first slider 462 and the second slider 463 can be moved on the slider 461 in a predetermined direction.

In some examples, the first slider 462 may be interlocked with the first clamping portion 43. The second slider 463 may be interlocked with the second clamping portion 44. In some examples, the first slider 462 may be moved closer to the second slider 463 to move the first and second clamping portions 43 and 44 closer to each other to clamp the neck 202. In some examples, the first slider 462 and the second slider 463 may be moved away from each other to move the first and second clamping portions 43 and 44 away from each other to release the neck 202.

In some examples, the first slider 462 may be interlocked with the second slider 463. In this case, the first slider 462 and the second slider 463 can be moved closer to or away from each other by controlling only the first slider 462, thereby simplifying control of the first clamping portion 43 and the second clamping portion 44 to clamp the neck portion 202.

Fig. 5A is a schematic diagram showing a pickup apparatus 400 according to an example of the present invention in a pickup state; fig. 5B is a schematic diagram illustrating the pickup device 400 according to the example of the present invention in a released state.

In some examples, the pick-up device 400 may also include a position detection mechanism 47 (see fig. 5). The position detection mechanism 47 may be used to detect whether the first clamping portion 43 and the second clamping portion 44 can approach each other to a position where they clamp the neck portion 202.

The position detection mechanism 47 includes a detection member 471 and a first sensor 472 (see fig. 5A and 5B). The detection member 471 may be interlocked with the first clamping portion 43. In some examples, the detection member 471 can also be linked with the first slider 462. The first clamping portion 43 may have a preset position. In some examples, the first and second clamping portions 43, 44 may clamp the neck 202 when the first clamping portion 43 is in the preset position. In some examples, the detection member 471 may have a preset detection area. The preset detection region may move when the first grip portion 43 moves due to the interlocking of the detection member 471 and the first grip portion 43. In some examples, the first sensor 472 may be aligned with a movement path of the preset detection area. In some examples, the preset detection region of the detection member 471 may correspond to a preset position of the first clamping portion 43. In this case, when the first sensor 472 detects the preset detection area of the detection member 471, it can be said that the first clamping portion 43 can reach the preset position to clamp the neck 202 in cooperation with the second clamping portion 44, and the situation that the first clamping portion 43 cannot reach the preset position to clamp the neck 202 can be adjusted in time.

In some examples, the detection member 471 may be sheet-like. The detection member 471 may have a first through hole 471a, a second through hole 471B, and a detection portion 471c (see fig. 5A and 5B). A common sidewall between the first through hole 471a and the second through hole 471b may be the sensing part 471c. In some examples, the first through hole 471a, the second through hole 471b, and the detecting portion 471c cooperate to constitute a preset detecting area. In some examples, the first sensor 472 may be used to detect the first through hole 471a, the second through hole 471b, and the detecting portion 471c. As shown in fig. 5A, in some examples, when the second through hole 471b is located directly below the first sensor 472, the first sensor 472 detects the second through hole 471b, which indicates that the first clamping portion 43 and the second clamping portion 44 are located at a position where the neck 202 cannot be clamped. As shown in fig. 5B, in some examples, when the detecting portion 471c is located directly below the second sensor 472, the first sensor 472 detects the detecting portion 471c, which indicates that the first clamping portion 43 and the second clamping portion 44 are at the preset position where the neck 202 can be clamped.

In some examples, the first sensor 472 may be a distance sensor.

While the present disclosure has been described in detail in connection with the drawings and examples, it should be understood that the above description is not intended to limit the disclosure in any way. Those skilled in the art can make modifications and variations to the present disclosure as needed without departing from the true spirit and scope of the disclosure, which fall within the scope of the disclosure.
