Description

Technical Field

[0001] This invention relates to the field of puncture and injection technology, and in particular to an automated puncture and injection device. Background Technology

[0002] Puncture-based drug delivery is a medical procedure that uses a syringe to deliver medication into the body through the skin, blood vessels, or muscles to achieve a therapeutic effect. Current methods require healthcare workers to hold the syringe, align it with the puncture site, insert the needle, and press the syringe handle to inject the medication. In situations such as sudden outbreaks of epidemics or pandemics, healthcare workers often need to perform multiple injections within a day. Furthermore, the smooth surface of the syringe requires considerable finger strength to hold, easily leading to hand fatigue. Hand fatigue increases the difficulty of injection, increases the likelihood of syringe misalignment, and poses a risk to patient safety due to accidental collisions during the injection process.

[0003] Therefore, an automated puncture-based drug delivery and injection device is proposed. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides an automated puncture drug delivery and injection device.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an automated puncture drug delivery and injection device, comprising an injection end and a driving end. The injection end includes a firing assembly and a clamping assembly. The clamping assembly is used to fix the syringe, and the firing assembly is used to control the puncture and injection action. The firing assembly includes a firing chamber, which is a frame with openings on the top and front. A control button is installed on the side of the firing chamber. A handle is connected to the rear end of the bottom surface of the firing chamber. A movable frame is connected to the bottom surface of the firing chamber in front of the handle. A groove is formed in the movable frame, and a trigger is fitted inside the groove. An elastic switch is provided at the end of the movable frame, and the pressing end of the elastic switch corresponds to the trigger. A through hole is formed at the rear end of the firing chamber, and the position corresponding to the through hole... The device is equipped with an electric actuator one, which is positioned as a drive shaft corresponding to the interior of the firing chamber. The clamping assembly includes a clamping frame. An electric actuator two is installed at the bottom of the firing chamber, with its drive shaft pointing upwards and connected to the clamping frame. The clamping frame has several sliding grooves. Slide rails are connected to both sides of the sliding grooves on the bottom surface of the clamping frame. Slide seats are slidably connected to the slide rails, and fixed plates are connected to the slide seats. A clamping plate is connected to the free end of the fixed plate. The clamping plate is located in the sliding groove. The end of the clamping plate above the clamping frame is curved, and the concave surfaces of the two clamping plates at corresponding positions are corresponding. Clamping components are provided in the sliding groove. The firing chamber contains a circuit board and a circuit compartment for accommodating the circuit board. The circuit board is used to receive signals from the switch and drive electric actuator one and electric actuator two.

[0006] In a preferred embodiment of the present invention, the driving end includes a controller, a connecting component, and a locking component. The controller has a control panel and includes a power supply and control circuit. The controller provides power to the injection end and controls operating parameters. The connecting component connects the injection end and the driving end and allows for position and angle adjustment. A placement frame for placing the firing component is connected to one side of the controller. The locking component locks the position and angle of the connecting component. The syringe is connected to the firing component via the locking component. Moving the syringe to the puncture injection position activates the firing component to initiate the puncture injection. The connecting component, via the locking component, maintains the position and angle of the firing component. The connecting component includes a linear module mounted on one side of the controller. A sliding frame is connected to the slider of the linear module, and elastic switches are installed on the sides of the sliding frame. The trigger end of the second elastic switch corresponds to the inside of the slide frame. A connecting seat is sleeved between the two second elastic switches inside the slide frame. The connecting seat is connected to the firing assembly through a hinge. The hinge includes a hinge plate, a second hinge, and a hinge seat. Both ends of the first hinge are rotatably mounted with a rotating shaft. One end of the second hinge is also rotatably mounted with a rotating shaft. Both ends of the first hinge are hinged to the connecting seat and the second hinge respectively through the rotating shaft. One end of the second hinge is hinged to the hinge seat through the rotating shaft. An electromagnet is mounted on the hinge seat. The bottom surface of the grip has a groove adapted to the electromagnet, and a magnetically sensing metal plate is connected in the groove. The locking assembly includes an electric push rod three. The electric push rod three is mounted on the connecting seat, the first hinge, and the hinge seat. The drive shaft of the electric push rod three corresponds to the rotating shaft. A rubber ring is connected to the outer wall of the rotating shaft. The drive shaft of the rotating shaft is connected to a locking ring. The locking ring is annular and has teeth on its inner ring.

[0007] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. By using the firing assembly, the syringe is held inside by the clamping assembly. The position of the syringe can be adjusted by holding the firing chamber, and the puncture and drug delivery can be performed by pulling the trigger. Therefore, there is no need to hold a smooth syringe or manually press the syringe handle, thus avoiding hand fatigue caused by large injections. It also avoids problems such as the syringe falling due to accidental collisions or syringe deviation during puncture and drug delivery, thereby improving the efficiency and stability of puncture and drug delivery and ensuring the effect of puncture and drug delivery.

[0008] 2. Through the setting of the connecting component, when adjusting the position before puncture and drug administration, the connecting component allows the firing component to have free forward, backward, left and right position control and horizontal and vertical angle control. When the trigger is pulled to trigger the puncture and drug administration action, it can automatically lock the position and angle, improve the stability of the syringe position during puncture and drug administration, reduce the possibility of deviation, and have a certain preventive effect on the risk of position deviation caused by accidental collision, thus improving the protection of the patient.

[0011] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0012] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an automated puncture and injection device includes an injection end and a drive end. The injection end includes a firing assembly and a clamping assembly. The firing assembly is used to control the puncture and injection action. The firing assembly includes a firing chamber 10, which is a frame with openings on the top and front. The firing chamber 10 is open on both the left and right sides and connected to a transparent observation window. A control button 11 is installed on the side of the firing chamber 10. A handle 12 is connected to the rear end of the bottom surface of the firing chamber 10. A movable frame 13 is connected to the bottom surface of the firing chamber 10 in front of the handle 12. A T-shaped groove is opened in the movable frame 13, and a trigger 14 is fitted inside the groove. An elastic switch 15 is provided at the end of the movable frame 13. The pressing end of the elastic switch 15 corresponds to the trigger 14. A through hole is opened at the rear end of the firing chamber 10, and an electric actuator 16 is installed at the position corresponding to the through hole. The electric actuator 16 is a drive shaft corresponding to the inside of the firing chamber 10.

[0013] Specifically, the syringe is mounted on the clamping assembly. By gripping the handle 12, the syringe is moved to the puncture and drug delivery position. The finger pulls the trigger 14, which contacts the elastic switch 15 and drives the puncture and drug delivery action. The electric plunger 16 receives the signal and drives the drive shaft to extend, pressing the syringe handle to push out the drug, thus achieving puncture and drug delivery. When the finger releases the trigger 14, the electric plunger 16 rebounds and stops the drug delivery, completing the puncture and drug delivery or facilitating a quick stop of the drug delivery action in case of an emergency. Pressing one of the control buttons 11 sends a reset signal to reset the electric plunger 16.

[0014] like Figure 4 and Figure 5 As shown, the clamping assembly is used to fix the syringe. The clamping assembly includes a clamping frame 17. An electric actuator 24 is installed at the bottom of the firing chamber 10. The drive shaft of the electric actuator 24 is upward and connected to the clamping frame 17. The clamping frame 17 has several sliding grooves 18. Slide rails 20 are connected to both sides of the sliding grooves 18 on the bottom surface of the clamping frame 17. A slide seat 21 is slidably connected to the slide rail 20. A fixing plate 22 is connected to the slide seat 21. A clamping plate 23 is connected to the free end of the fixing plate 22. The clamping plate 23 is located in the sliding groove 18. The end of the clamping plate 23 above the clamping frame 17 is curved, and the two clamping plates 23 at corresponding positions have concave surfaces. The slide groove 18 is equipped with a clamping component, which can be a double-ended screw or a spring. The two ends of the double-ended screw are threaded to two clamping plates 23 respectively. Rotating the double-ended screw can make the two clamping plates 23 move closer or further apart. In this embodiment, the clamping component is a spring. A guide rod 19 is connected in the slide groove 18. The clamping plate 23 has a through hole and is slidably connected to the guide rod 19. Two springs are sleeved on the guide rod 19, which respectively abut against the slide groove 18 and the clamping plate 23. The firing chamber 10 is equipped with a circuit board and a circuit compartment for accommodating the circuit board. The circuit board is used to receive the switch signal and drive the electric actuator 16 and the electric actuator 24.

[0015] Specifically, the syringe is installed between two clamping plates 23. The clamping plates 23 can adjust the spacing by sliding the fixing plate 22 on the slide rail 20 to accommodate syringes of different sizes. The syringe is fixed by the pressure of the spring, which improves the stability of the syringe. Then, one of the control buttons 11 is pressed, and the drive shaft of the second electric actuator 24 retracts, causing the clamping frame 17 to descend, allowing the syringe to enter the firing chamber 10. This prevents accidental external contact that could cause the syringe to deviate, and aligns the syringe with the first electric actuator 16. Pressing one of the control buttons 11 sends a reset signal, causing the drive shaft of the second electric actuator 24 to extend and reset, so that the syringe can be operated in the appropriate position.

[0016] like Figure 1 As shown, the drive end includes a controller 38, a connecting component, and a locking component. The controller 38 is equipped with a control panel and a handle. The controller 38 contains a power supply and control circuit. The controller 38 is used to provide power to the injection end and control the operating parameters. A placement frame 37 for placing the firing component is connected to one side of the controller 38.

[0017] like Figure 1 and Figure 6 As shown, the connecting assembly is used to connect the injection end and the driving end and allows for position and angle adjustment. The connecting assembly includes a linear module 25, which is mounted on one side of the controller 38. A sliding frame 26 is connected to the slider of the linear module 25. A second elastic switch 27 is mounted on each side of the sliding frame 26. The trigger end of the second elastic switch 27 corresponds to the interior of the sliding frame 26. A connecting seat 28 is sleeved between the two second elastic switches 27 inside the sliding frame 26. The connecting seat 28 is connected to the firing assembly via a hinge. The hinge includes a first hinge plate 29 and a second hinge plate 30. Both ends of the hinge plate 29 and the hinge base 31 are rotatably mounted with a rotating shaft 32. The hinge plate 30 and the hinge base 31 are also rotatably mounted with a rotating shaft 32 at one end. The two ends of the hinge plate 29 are respectively hinged to the connecting base 28 and the hinge plate 30 via the rotating shaft 32. One end of the hinge plate 30 is hinged to the hinge base 31 via the rotating shaft 32. An electromagnet 33 is hinged and mounted on the hinge base 31 via the rotating shaft 32. The bottom surface of the handle 12 has a groove adapted to the electromagnet 33 and a magnetically sensitive metal plate is connected in the groove. The magnetically sensitive metal plate is a metal material that can be attracted by a magnet.

[0018] Specifically, when holding the handle 12, if the position of the handle 12 is to be adjusted forward or backward, a pushing or pulling force is applied to the connecting seat 28. The connecting seat 28 first slides within the slide frame 26 and triggers the second elastic switch 27. According to the triggered elastic switch 27, the linear module 25 drives the connecting seat 28 to move forward or backward. When the trigger 14 is pulled to trigger the puncture and drug delivery action, the signal sent by the first elastic switch 15 locks the linear module 25, thereby locking the forward and backward position of the firing component, ensuring that the forward and backward position of the firing component is stable during puncture and drug delivery. When in the attached state, the firing assembly is inserted into the placement frame 37. When needed, the firing assembly is removed, the electromagnet 33 is activated, and the electromagnet 33 attracts and fixes the handle 12, thus fixing the firing assembly onto the connecting assembly. The firing assembly can be set on the hinge seat 31 via the rotating shaft 32, and rotate laterally on the electromagnet 33 with the rotating shaft 32 as the axis. The hinge seat 31 rotates longitudinally on the second hinge plate 30, the second hinge plate 30 rotates laterally on the first hinge plate 29, and the first hinge plate 29 rotates longitudinally on the connecting seat 28, thereby allowing the position of the firing assembly to be freely adjusted.

[0019] like Figure 1 , Figure 6 As shown, the locking assembly is used to lock the position and angle of the connecting assembly. The locking assembly includes an electric actuator 34, which is mounted on the connecting seat 28, the hinge plate 29, and the hinge seat 31. The drive shafts of several electric actuators 34 correspond to several rotating shafts 32. A rubber ring 35 is connected to the outer wall of the rotating shaft 32. A locking ring 36 is connected to the drive shaft of the rotating shaft 32. The locking ring 36 is annular and has teeth on its inner ring. The syringe is connected to the firing assembly via the locking assembly. When the syringe is moved to the puncture injection position, the firing assembly is activated to open the puncture injection. The connecting assembly is fixed by the locking assembly to maintain the position and angle of the firing assembly.

[0020] Specifically, when administering medication via puncture, after pressing the trigger 14 to send a signal, the electric actuator 34 controls the locking ring 36 to extend, abut against the rubber ring 35, and uses the gear teeth to lock the rubber ring 35, thereby restricting the rotation of the rotating shaft 32, and locking the firing assembly at a fixed position and fixed angle, increasing stability during puncture medication administration.

[0021] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
