Description

Technical Field

[0001] This invention relates to the field of medical devices, and in particular to a method for administering medication to different ampoules. Background Technology

[0002] Injectable drugs are also known as powders and liquids. Liquids are mainly packaged in ampoules. However, ampoules are made of glass, which makes them easy to break and poses a safety risk when holding them.

[0003] In response to the above problems, our company filed an invention patent application with publication number "CN110960422A" on April 7, 2020, which disclosed an aqueous preparation machine that uses a syringe to extract the medicine from the ampoule. However, the ampoules have different sizes, that is, the depth of the ampoules is inconsistent, and the extraction needle cannot completely extract the medicine from the bottom of the ampoule. Summary of the Invention

[0004] The purpose of this invention is to provide a method for adding medication to different ampoules, which has the advantage of completely removing the medication from the bottom of the ampoule.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a method for administering medication to different ampoules, comprising the following steps,

[0006] Step 1: Clamping the ampoule. The ampoule is clamped by a clamp that ensures that the ampoule can be displaced downwards a certain distance after receiving a downward force in the height direction.

[0007] Step 2: Moving the syringe needle. By moving the syringe vertically, the syringe needle is inserted into the ampoule.

[0008] Step 3: Pushing the liquid collection needle. By further moving the syringe downwards in the height direction, the liquid collection needle comes into contact with the bottom of the ampoule and drives the ampoule to move downwards on the gripper.

[0009] Step 4: Extract the medication by moving the syringe plunger upwards.

[0010] Preferably, a sliding channel for the ampoule to slide downwards is provided between the grippers.

[0011] By adopting the above technical solution, in step three, the ampoule moves downward after being subjected to the force of the liquid-taking needle.

[0012] Preferably, the gripper includes a left gripper and a right gripper, and the sliding channel is disposed between the left gripper and the right gripper.

[0013] By adopting the above technical solution, the ampoule bottle can be clamped and a sliding channel can be formed.

[0014] Preferably, the bottom of the left gripper is provided with a left meshing gear, and the bottom of the right gripper is provided with a right meshing gear, and the left meshing gear and the right meshing gear cooperate.

[0015] By adopting the above technical solution, the left and right grippers are prevented from clamping too tightly, and the gap between the left and right meshing gears can ensure the downward movement of the ampoule while clamping it.

[0016] Preferably, in step one, the grippers are tilted outwards.

[0017] By adopting the above technical solution, the lowest point is created inside the ampoule.

[0018] Preferably, the syringe is in contact with the lowest point of the bottom of the ampoule.

[0019] By adopting the above technical solution, it is easy to completely extract the reagent.

[0020] Preferably, in step four, after the syringe draws in the medication, air is continuously drawn in.

[0021] By adopting the above technical solution, residual liquid in the ampoule can be avoided.

[0022] Preferably, in steps two and three, the syringe is moved in the height direction by the electric screw.

[0023] By adopting the above technical solutions, the movement becomes more precise and smoother.

[0024] Preferably, in step four, the syringe core moves in the height direction within the syringe via an electric screw.

[0025] By adopting the above technical solutions, the movement becomes more precise and smoother.

[0026] Preferably, the liquid collection needle and syringe are located directly above the gripper.

[0027] In summary, by moving the syringe vertically into the ampoule and contacting the bottom of the ampoule, it moves further downwards to avoid gaps between the bottom of the ampoule and the syringe, thus ensuring complete extraction of the medication and preventing residual liquid.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings.

[0034] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0035] Example:

[0036] like Figures 1 to 4 As shown, a method for applying medication to different ampoules includes the following steps:

[0037] Step 1: Clamping the ampoule. The ampoule is clamped by the clamp 9, which is tilted outward. The dispensing needle 8 and the syringe 7 are located directly above the clamp 9. The clamp 9 ensures that the ampoule can be displaced downward a certain distance after receiving a downward force in the height direction.

[0038] Step 2: Moving the liquid collection needle 8. The syringe 7 moves in the height direction via the electric screw, inserting the liquid collection needle 8 of the syringe 7 into the ampoule.

[0039] Step 3: Pushing the liquid collection needle 8 by further moving the syringe 7 downward in the height direction, so that the liquid collection needle 8 comes into contact with the bottom of the ampoule, that is, the liquid collection needle 8 contacts the lowest point of the bottom of the ampoule, and drives the ampoule to move downward on the clamp 9.

[0040] Step 4: Extracting the medication. The syringe 7 core moves vertically within the syringe 7 via an electric screw, causing the syringe 7 core to move upwards to extract the medication. After the medication is extracted, some air is continuously drawn in to ensure complete extraction of the liquid from the ampoule.

[0041] like Figures 1 to 4As shown, a medication loading structure suitable for different ampoules includes a base 1, a first support 2, a first electric screw 3, a lifting platform 4, a second support 5, a second electric screw 6, a syringe 7, and a dispensing needle 8. The base 1 is mounted on the frame of the water injection machine, the first support 2 is mounted on the base 1, and the first electric screw 3 is located inside the first support 2. The first electric screw 3 controls the lifting platform 4 to move vertically, thereby controlling the syringe 7 and the dispensing needle 8 to move vertically. The second support 5 is located at the bottom of the lifting platform 4, the syringe 7 is located on the front of the second support 5, and the second electric screw 6 is located on the back of the second support 5. The syringe 7 core... A connecting block is provided at the tail end, which is connected to the second electric lead screw. The second electric lead screw 6 drives the syringe 7 core to move up and down in the height direction inside the syringe 7. At the same time, the gripper 9 is located below the syringe 7. That is, when the gripper 9 moves, it will pass under the syringe 7. A sliding channel for the ampoule to slide downward is provided between the grippers 9. The grippers 9 include a left gripper 9 and a right gripper 9. The sliding channel is located between the left gripper 9 and the right gripper 9. A left meshing gear is provided at the bottom of the left gripper 9, and a right meshing gear is provided at the bottom of the right gripper 9. The left meshing gear and the right meshing gear cooperate. By rotating the left meshing gear or the right meshing gear, the opening and closing of the left gripper 9 and the right gripper 9 are controlled.

[0042] Furthermore, the method also includes cases where the liquid collection needle tube 8 is separated from the syringe 7, that is, the liquid collection needle tube 8 and the syringe 7 are connected by a hose, and the electric screw drives the liquid collection needle tube 8 or the structure equipped with the liquid collection needle tube 8 to move in the height direction.
