Description

Technical Field

[0001] This utility model belongs to the field of drug extraction device technology, specifically an electric drug extraction device. Background Technology

[0002] During a patient's hospitalization, medication preparation is involved in various procedures, including general ward medications, intensive care unit medications, and operating room anesthetics. Medical staff need to use different syringes for medication preparation and injection. The frequent drawing of medication can easily cause hand pain for medical staff. Furthermore, staff are at high risk of accidentally injuring themselves with the needle while drawing medication, thus affecting work efficiency. Additionally, the medications used in preparation have a limited shelf life; premature manual drawing in pursuit of efficiency can lead to drug deterioration and compromise sterility. Moreover, the incomplete aspiration of medication can cause needle bending and breakage, potentially leading to serious medical accidents.

[0003] To address the problems raised in the background art, those skilled in the art have proposed an electric drug extraction device.

[0004] The information disclosed above in this background section is only intended to enhance the understanding of the background section of this utility model, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that the drawings are schematic and not illustrated to scale. For clarity and convenience, the relative sizes and proportions of the parts shown in the drawings have been exaggerated or reduced in size. Any size is only illustrative and not limiting.

[0022] Please see Figure 1 - Figure 3 As shown, an electric drug aspirator includes a base 1, a lifting seat 2 on the base 1, a syringe seat 3 mounted on the lifting seat 2, movable clamps 4 on both sides of the syringe seat 3, and an electric push plate 5 mounted on one end of the syringe seat 3. The movable clamp 4 includes a through groove 41 opened in the middle of the syringe seat 3, a bidirectional lead screw 42 is provided in the through groove 41, and a first driving member 43 is installed inside the syringe seat 3. The first driving member 43 is connected to the bidirectional lead screw 42 in a transmission connection.

[0023] Specifically, the base 1 is used to install and fix this device, the lifting seat 2 can control the lifting and lowering of the syringe seat 3, the syringe seat 3 holds the syringe, the movable clamp 4 can clamp the syringe from both sides of the syringe seat 3, and at the same time, the movable clamp 4 can determine the diameter of the syringe by the distance it moves, thus determining the syringe model, the electric push plate 5 can push the piston rod of the syringe, and the volume of injection and aspiration can be controlled by controlling the moving distance of the electric push plate 5.

[0024] Please see Figure 4As shown, the movable clamp 4 is installed in the through groove 41, and the bidirectional lead screw 42 is rotatably connected to the syringe seat 3. For example, brackets can be installed on both sides of the syringe seat 3, and the two ends of the bidirectional lead screw 42 are rotatably connected to the brackets. A gear is provided at the center of the bidirectional lead screw 42. The first driving member 43 includes a drive motor installed in the syringe seat 3. The output end of the drive motor is provided with a drive gear that meshes with the gear of the bidirectional lead screw 42, thereby controlling the number of rotations of the bidirectional lead screw 42 according to the number of rotations of the drive motor. The two movable clamps 4 move relative to each other or towards each other along the bidirectional lead screw 42. The first driving member 43 can be remotely controlled or wired controlled.

[0025] The motor of the first driving component 43 rotates to control the movement of the movable clamp 4 towards the center, thereby clamping the syringe. The number of rotations controls the movement distance of the movable clamp 4, thus determining the distance between the two movable clamps 4, which in turn determines the syringe model and volume.

[0026] Please see Figure 2 As shown, a baffle 31 is installed at the bottom of the syringe holder 3, a fixing clip 32 is installed at the top of the syringe holder 3, a groove is provided on the surface of the syringe holder 3, the baffle 31 is used to prevent the syringe from slipping, and the baffle 31 is provided with a through hole for the syringe head to pass through, and also serves as a limit.

[0027] Please see Figure 2 As shown, the electric push plate 5 further includes a motor installed inside the syringe holder 3. The syringe holder 3 is rotatably connected to a push screw 51. The electric push plate 5 is fixedly connected to a connecting plate 53. The connecting plate 53 is threadedly engaged with the push screw 51. The motor drives the push screw 51 to rotate. When the push screw 51 rotates, the connecting plate 53 drives the electric push plate 5 to move radially along the push screw 51, thereby precisely controlling the injection of the syringe.

[0028] Please see Figure 2 As shown, the difference is that a movable lead screw 61 is installed on the base 1, and a second driving component 62 is also provided on the base 1. The second driving component 62 is connected to the movable lead screw 61 in a transmission connection. The movable lead screw 61 is connected to a movable seat 63, and the movable seat 63 is threadedly engaged with the movable lead screw 61. Several conversion seats 64 are installed on the movable seat 63, and converters 6 and pressure sensors 65 are installed on the conversion seats 64.

[0029] Specifically, the second driving component 62 can drive the moving lead screw 61 to rotate, the moving lead screw 61 drives the moving seat 63 to move, the moving seat 63 can move the conversion seat 64, and the conversion seat 64 is equipped with a converter 6. Several conversion seats 64 are provided, thus providing several converters 6. Each converter 6 has a different function. For example, it can be equipped with a liquid connection port for connecting to an external medicine pipeline, an ampoule holder for placing an opened ampoule for extraction, and a needle clamp for attaching a needle to the syringe. At the same time, a pressure sensor 65 is installed on the conversion seat 64. When the syringe reaches the bottom of the converter 6, pressure is applied, and the pressure sensor 65 sends a signal to indicate that the syringe has reached the designated position.

[0030] Please see Figure 3 As shown, the lifting seat 2 further includes several lifting rods 21 set on the base 1. A lifting plate 22 is fixedly installed at the top of the lifting rod 21. Several rotating wheels 25 are provided in the middle of the lifting plate 22. The lifting seat 2 can control the lifting of the syringe seat 3, thereby driving the syringe to descend and controlling the syringe head to extend into the converter 6.

[0031] Please see Figure 2 - Figure 3 As shown, a fixing plate 23 is further installed on the base 1. There are two fixing plates 23 symmetrically arranged about the syringe seat 3. The fixing plate 23 has a fixing protrusion 24 on the surface facing the syringe seat 3. Inclined sliding grooves are opened on both sides of the syringe seat 3. The fixing protrusion 24 slides with the sliding groove. By setting the sliding groove and the fixing protrusion 24, the syringe can be guided to move at an angle when it is raised and lowered. At this time, the syringe seat 3 can move on each rotating wheel 25, so that the syringe head can be inserted into each inclined converter 6.
