Description

Technical Field

[0001] This application relates to the technical field of medical auxiliary equipment, and in particular to an infusion injection auxiliary device. Background Technology

[0002] With the continuous development of medical technology, medical staff face increasing challenges when performing intravenous infusion procedures. Traditional infusion methods often require manual operation and frequent changes of infusion containers, which not only increases the difficulty of their work but also reduces efficiency. To address this issue, infusion injection assistive devices have emerged.

[0003] This device, through automated control, can simultaneously preset multiple infusion containers and automatically connect the puncture needle to the infusion containers in a predetermined sequence, thereby achieving multiple automatic infusions. However, existing infusion injection auxiliary devices have certain problems during use: because the puncture sites of the infusion containers are equipped with sterile protective caps, the device cannot control the puncture needle to pierce the puncture site if the protective caps are not removed.

[0004] Therefore, in practice, medical staff need to manually remove the sterile protective cap beforehand. This not only increases the workload of medical staff, but also exposes the puncture site after removing the cap, making it susceptible to contamination during prolonged infusion. This not only increases medical risks but also reduces the safety and reliability of the infusion procedure. Utility Model Content

[0005] To address the aforementioned problems, this application provides an infusion injection auxiliary device.

[0006] This application provides an infusion injection auxiliary device, which adopts the following technical solution:

[0007] An infusion injection auxiliary device includes a transfer mechanism for storing infusion containers and switching workstations, an automatic puncture mechanism for controlling the raising and lowering of a puncture needle, a cap removal mechanism for removing sterile protective caps, and a mounting frame for mounting the transfer mechanism, the automatic puncture mechanism, and the cap removal mechanism. The cap removal mechanism includes a pull-ring type cap removal assembly that removes the cap by hooking a pull-ring type protective cap during transfer, and / or a cap type cap removal assembly that removes a cap type protective cap by cutting during transfer.

[0008] In one embodiment, the pull-ring cap removal assembly includes a hook for inserting a ring-shaped sterile protective cap and an elastic element for pushing the ring-shaped sterile protective cap out of the hook, the hook being mounted on a mounting bracket.

[0009] In one embodiment: the hook includes a lifting body that slides vertically on the mounting frame, a hook body provided on the lifting body, and a reset member that provides an upward tendency force to the lifting body; the transfer mechanism is provided with an obstacle avoidance component for pushing the lifting body downward.

[0010] In one embodiment, the obstacle avoidance assembly includes an obstacle avoidance drive mounted on the transfer mechanism and an obstacle avoidance rod controlled by the lifting and lowering of the obstacle avoidance drive.

[0011] In one embodiment: the elastic element is a unloading spring, which is installed on the hook and sleeved on the hook body.

[0012] In one embodiment: the cap removal assembly includes a cutter-type thumb ring.

[0013] In one embodiment, the cap removal assembly further includes a cutting motor for driving the cutting ring to rotate for auxiliary cutting, wherein the direction of rotation of the cutting ring driven by the cutting motor is opposite to the direction of rotation of the transfer mechanism.

[0014] In one embodiment: the cutting-type finger is connected to the cutting motor via an integrally formed connecting arm, and the height of the cutting edge of the cutting-type finger is higher than the height of the connecting arm.

[0015] In one embodiment, a storage box with an upward opening is provided below the cutter-shaped thumb ring.

[0016] In one embodiment: the mounting bracket is equipped with an ultraviolet disinfection lamp that can irradiate the puncture site.

Detailed Implementation

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0027] An infusion injection auxiliary device, such as Figure 1 As shown, it includes a transfer mechanism 200 for storing infusion containers and switching workstations, an automatic puncture mechanism 300 for controlling the raising and lowering of puncture needles, a cap removal mechanism 400 for removing sterile protective caps, and a mounting bracket 100 for mounting the transfer mechanism 200, the automatic puncture mechanism 300 and the cap removal mechanism 400.

[0028] The transfer mechanism 200 is a turntable controlled by a motor drive. Multiple infusion containers can be installed on the turntable; in this embodiment, four are used as an example.

[0029] The automatic puncture mechanism 300 includes a puncture needle mounting seat 310 for detachably mounting a puncture needle, and a puncture electric push rod 320 for controlling the movement of the puncture needle mounting seat 310. The puncture electric push rod 320 is mounted on the mounting frame 100, and the puncture needle mounting seat 310 is mounted on the telescopic rod of the puncture electric push rod 320. The puncture needle mounting seat 310 is provided with a mounting groove for the puncture needle to be inserted and engaged.

[0030] like Figure 2As shown, the cap removal mechanism 400 includes a pull-ring cap removal component 410 that removes the cap by hooking the pull-ring protective cap during transport, and / or a cap removal component 420 that removes the cap-type protective cap by cutting during transport. Only one of the pull-ring cap removal component 410 or the cap removal component 420 may be provided, or both may be provided simultaneously, depending on the application scenario. This embodiment uses simultaneous provision as an example.

[0031] See attached document Figure 3 The pull-ring cap removal assembly 410 includes a hook 411 for inserting a ring-shaped sterile protective cap and an elastic element 412 for pushing the ring-shaped sterile protective cap out of the hook 411.

[0032] Combined with appendix Figure 4 The hook 411 includes a lifting body 4111 that is slidably mounted on the mounting frame 100 in a vertical direction, a hook 4112 provided on the lifting body 4111, and a reset member 4113 that provides an upward tendency force to the lifting body 4111. The lifting body 4111 is provided with a plurality of sliding rods, which are slidably mounted on the mounting frame 100. The reset member 4113 is a reset spring and is sleeved on the sliding rod. The two ends of the reset member 4113 abut against the mounting frame 100 and the lifting body 4111 respectively to form a reset tendency force.

[0033] The hook body 4112 is a straight rod structure extending outward from one side of the lifting body 4111. The elastic element 412 is a unloading spring, which is installed on the hook 411 and sleeved on the hook body 4112. The end of the hook body 4112 is designed with a blade-shaped structure to facilitate insertion into the pull ring.

[0034] like Figure 2 As shown, the transfer mechanism 200 is equipped with an obstacle avoidance assembly 500 for pushing the lifting body 4111 downwards. The obstacle avoidance assembly 500 includes an obstacle avoidance drive 510 mounted on the transfer mechanism 200 and an obstacle avoidance rod 520 controlled by the obstacle avoidance drive 510. The obstacle avoidance drive 510 can be a cylinder, an electromagnetic push rod, etc. The obstacle avoidance rod 520 is mounted on the telescopic rod of the obstacle avoidance drive 510, and its lower end is hammer-shaped with rounded or chamfered corners.

[0035] The obstacle avoidance lever 520 can be either extended or retracted in its initial state. When extended, the lever 411 is pressed by default, making it unable to be removed. When retracted, the lever 411 is not pressed by default, making it able to be removed.

[0036] like Figure 3As shown, the cap removal assembly 420 includes a cutter-type finger 421 and a cutter motor 422 for driving the cutter-type finger 421 to rotate for auxiliary cutting. The direction of rotation of the cutter-type finger 421 driven by the cutter motor 422 is opposite to the direction of rotation of the turntable of the transfer mechanism 200.

[0037] The cutting finger 421 is connected to the cutting motor 422 via an integrally set connecting arm 423. The height of the cutting edge of the cutting finger 421 is higher than the height of the connecting arm 423, and one side of the cutting finger 421 is set with a cutting edge structure.

[0038] During use, if the cap cover does not need to be removed, the cutter motor 422 will not start, and the cap cover will pass over the connecting arm 423. If the cap cover needs to be removed, the cutter motor 422 will start, and the cutter-type wrench 421 will swing and contact the cap cover during rotation to cut it.

[0039] For easy storage, a storage box 600 with an upward opening is provided below the cutter-shaped thumb ring 421.

[0040] Because there may be situations where multiple infusion procedures are required within an infusion container—for example, after infusion container A has been used halfway, it needs to be switched to infusion container B, and then infusion container A is used again for the next infusion—it is necessary to disinfect the exposed puncture site, such as... Figure 1 As shown, an ultraviolet disinfection lamp 700 can also be installed on the mounting frame 100, and the cap removal mechanism 400 is preferably located between the ultraviolet disinfection lamp 700 and the automatic puncture mechanism 300.

[0041] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
