Abstract
Description
Technical Field
[0001] This utility model relates to the field of anesthetic drug injection technology, specifically to a portable drug injector. Background Technology
[0002] Anesthetic drugs play a crucial role in clinical surgery, ensuring patients are painless, unconscious, and have relaxed muscles during the procedure. However, there are many types of anesthetic drugs, each with strict requirements regarding its mechanism of action, dosage, timing, and order of administration. Common anesthetic drugs include sedatives, analgesics, muscle relaxants, and inhaled anesthetics. Combinations of these drugs can provide comprehensive anesthesia, but also increase the complexity of the procedure. The order of drug administration is critical, relying heavily on the anesthesiologist's experience and memory. However, the stressful surgical environment and the immense workload faced by anesthesiologists can lead to distraction and errors, potentially resulting in incorrect drug administration and increased surgical risks. Utility Model Content
[0003] This invention proposes a convenient drug injector, which solves the problem that the administration of anesthetic drugs in related technologies mainly relies on the experience and memory of anesthesiologists, which can easily lead to distraction and operational errors, potentially causing incorrect drug administration sequence and increasing surgical risks.
[0004] The technical solution of this utility model is as follows: A portable drug injector, comprising:
[0005] A first injection plate is rotatably disposed. The first injection plate has multiple first through holes, multiple first marks, and multiple second marks. The first marks and second marks are distributed on the periphery of the first injection plate. The first marks are located in the extension direction of the line connecting the rotation axis of the first injection plate and the center of the first through hole. The second marks are located between two adjacent first marks.
[0006] The second injection plate is located on one side of the first injection plate and has a second through hole and a third mark. The third mark is located on the periphery of the second injection plate. After the first injection plate is rotated, one of the first through holes communicates with the second through hole and one of the first marks corresponds to the third mark. Alternatively, after the first injection plate is rotated, the first through hole and the second through hole are not communicated and one of the second marks corresponds to the third mark.
[0007] Optionally, the first mark, the second mark, and the third mark may be grooves, raised areas, or painted with different colors.
[0008] Optionally, it also includes:
[0009] A screwing part is disposed on the first injection plate. When the screwing part rotates, it drives the first injection plate to rotate synchronously.
[0010] Optionally, it also includes:
[0011] A plurality of drug tubes are disposed on the first injection plate, and each drug tube communicates with a first through hole.
[0012] Optionally, the medicine tube has a split structure, having a first tube section and a second tube section, with the second tube section movably disposed on the first tube section, and after the second tube section is moved, one end of it approaches or moves away from the first tube section.
[0013] Optionally, it also includes:
[0014] A first sleeve has a first inner cavity, in which a plurality of the drug tubes are disposed. The second tube extends out of or moves into the first inner cavity after being moved.
[0015] Optionally, the first sleeve has a guide groove, the guide groove having a communicating horizontal section and an arc-shaped section, and further includes:
[0016] A connector, one end of which is disposed on the second tube and the other end is movably disposed within the guide groove.
[0017] Optionally, it also includes:
[0018] The second sleeve is disposed on the second injection plate and has a second inner cavity, and the second through hole communicates with the second inner cavity.
[0019] Optionally, it also includes:
[0020] A hanging component, which is connected to the first sleeve and the second sleeve, and has a hanging opening.
[0021] Optionally, the second sleeve has a drug outlet, the diameter of which is smaller than the cross-sectional diameter of the second inner cavity, and is in communication with the second inner cavity.
[0022] The working principle and beneficial effects of this utility model are as follows:
[0023] In this invention, taking a first injection plate with three first through holes, three first markings, and three second markings as an example, when drug injection is required, the first injection plate is rotated while the second injection plate remains fixed, aligning one of the first through holes with the second through hole and simultaneously aligning one of the first markings with the third marking, indicating the type or sequence of the drug being injected. After injection, the first injection plate is rotated again, aligning another first through hole with the second through hole and continuing to inject the second drug. This process is repeated to complete the sequential injection of multiple drugs. Because the rotation enables the sequential connection of multiple first through holes with the second through holes, the order can be controlled. When drug injection is not required, the first injection plate can be rotated to align the first marking with the third marking. In this case, the first through hole and the second through hole are not connected, preventing accidental administration of the wrong drug when no medication is needed.
[0024] The alignment of the first and third markers in this scheme clearly indicates the type or order of the currently injected medication, reducing the burden of memory. Each rotation of the first injection plate ensures real-time guidance between the first and third markers, preventing operational errors. This achieves accurate management of the injection sequence and dosage. Its working principle is simple and intuitive, easy to operate, and effectively improves operational accuracy and patient safety. By reducing the burden of memory and operational steps, it improves work efficiency and medical quality, is suitable for various clinical scenarios, and has broad application prospects.

[0035] Reference Figures 1-4A convenient drug injector is proposed, comprising: a first injection plate 1, which is rotatably configured and has multiple first through holes 101, multiple first markings 102, and multiple second markings 103. The first markings 102 and second markings 103 are distributed around the periphery of the first injection plate 1. The first markings 102 are located in the extension direction of the line connecting the rotation axis of the first injection plate 1 and the center of the first through hole 101, and the second markings 103 are located between two adjacent first markings 102; and a second injection plate 2, which is located on one side of the first injection plate 1 and has a second through hole 201 and a third marking 202. The third marking 202 is located around the periphery of the second injection plate 2. After the first injection plate 1 is rotated, one of the first through holes 101 communicates with the second through hole 201, and one of the first markings 102 corresponds to the third marking 202.
[0036] In this embodiment, taking the first injection plate 1 having three first through holes 101, three first markings 102, and three second markings 103 as an example, when drug injection is required, the first injection plate 1 is rotated, while the second injection plate 2 remains fixed, so that one of the first through holes 101 is aligned and connected with the second through hole 201, and one of the first markings 102 is aligned with the third marking 202, indicating the type or order of the drug being injected. After the injection is completed, the first injection plate 1 is rotated so that another first through hole 101 is aligned and connected with the second through hole 201, and the injection of the second drug continues. This process is repeated to complete the sequential injection of multiple drugs. Because the rotation enables the sequential connection of multiple first through holes 101 with the second through holes 201, the order can be controlled. When drug injection is not required, the first injection plate 1 can be rotated so that the first marking 102 is aligned with the third marking 202. At this time, the first through hole 101 and the second through hole 201 are not connected, avoiding the mistake of administering the wrong drug when it is not needed.
[0037] The alignment of the first mark 102 and the third mark 202 clearly indicates the type or sequence of drugs being injected, reducing the burden of memory. Each time the first injection plate 1 is rotated, the alignment of the first mark 102 and the third mark 202 provides real-time operational guidance, preventing operational errors. This achieves accurate management of drug injection sequence and dosage. Its working principle is simple and intuitive, and its operation is convenient, effectively improving operational accuracy and patient safety. By reducing the burden of memory and operational steps, it improves work efficiency and medical quality, is suitable for various clinical scenarios, and has broad application prospects.
[0038] Furthermore, the first mark 102, the second mark 103, and the third mark 202 are grooves, raised areas, or painted with different colors.
[0039] In this embodiment, the first marking point 102, the second marking point 103, and the third marking point 202 can be designed as grooves or protrusions. Grooves or protrusions can provide clear visual and tactile identification, allowing operators to confirm the position of the markings by touch or sight, and to confirm the alignment of the markings by touch.
[0040] Meanwhile, the first mark 102, the second mark 103, and the third mark 202 can be painted with different colors. Different colors can provide a clear visual distinction, allowing operators to quickly identify different marks and visually confirm the color of the marks to ensure the correct alignment or dealignment of the first through hole 101 and the second through hole 201.
[0041] Furthermore, a screwing part 3 is provided on the first injection plate 1. After the screwing part 3 rotates, it drives the first injection plate 1 to rotate synchronously.
[0042] In this embodiment, the screw-on part 3 is disposed on the first injection plate 1 and is fixedly connected to the first injection plate 1 or connected via a mechanical transmission mechanism. When the operator screws on the screw-on part 3, the rotation of the screw-on part 3 will drive the first injection plate 1 to rotate synchronously. After the first injection plate 1 rotates, one of the first through holes 101 aligns with the second through hole 201, and one of the first marks 102 aligns with the third mark 202, indicating the type and order of the drug currently being injected. The drug is injected into the patient through the first through hole 101 and the second through hole 201. The screw-on part 3 is continued to be screwed on so that the next first through hole 101 aligns with the second through hole 201, and the above steps are repeated until all drugs are injected in the correct order and dosage. The position of the first injection plate 1 can be easily adjusted by the screw-on part 3 to adapt to different clinical scenarios and operational requirements.
[0043] Furthermore, it also includes: multiple drug tubes 4, disposed on the first injection plate 1, each drug tube 4 communicating with a first through hole 101. The drug tube 4 has a split structure, having a first tube section 401 and a second tube section 402. The second tube section 402 is movably disposed on the first tube section 401, and after the second tube section 402 moves, one end approaches or moves away from the first tube section 401. A first sleeve 5 has a first inner cavity 501, in which multiple drug tubes 4 are disposed. After the second tube section 402 moves, it extends out of or moves into the first inner cavity 501.
[0044] In this embodiment, the drug tube 4 is located in the first inner cavity 501. The first tube portion 401 is fixed on the first injection plate 1. By pushing or pulling the second tube portion 402, one end of it is moved closer to or further away from the first tube portion 401. When the second tube portion 402 extends out of the first inner cavity 501, the length of the drug tube 4 increases; when the second tube portion 402 moves into the first inner cavity 501, the length of the drug tube 4 shortens.
[0045] When the first injection plate 1 rotates, the first through hole 101 aligns with the second through hole 201, and the corresponding drug tube 4 connects with the second through hole 201. Pushing the second tube 402 causes the drug tube 4 to extend out of the first inner cavity 501, injecting the medication into the patient through the first through hole 101 and the second through hole 201. Continue to rotate the rotating part 3 to align the next first through hole 101 with the second through hole 201, repeating the above steps until all medications are injected in the correct order and dosage. The split structure and telescopic function of the drug tube 4 allow its length to be adjusted as needed, improving operational flexibility. The telescopic function of the drug tube 4 allows the device to adapt to different injection environments and patient needs, enhancing the applicability of the equipment. The telescopic function of the drug tube 4, combined with the rotation of the first injection plate 1, ensures the correct injection sequence and dosage, improving the patient's treatment effect and safety.
[0046] Furthermore, the first sleeve 5 has a guide groove 502, which has a horizontal section 503 and an arc-shaped section 504 communicating with each other, and also includes:
[0047] Connector 6, one end of which is disposed on the second tube 402, and the other end is movably disposed in the guide groove 502.
[0048] In this embodiment, when the operator rotates the first injection plate 1, the first injection plate 1 drives the three drug tubes 4 to rotate synchronously. The connector 6 moves within the guide groove 502. When the connector 6 moves from the horizontal section 503 to the arc-shaped section 504, the connector 6 is guided by the arc-shaped section 504 and gradually rises. Simultaneously, the connector 6 rises, causing the second tube section 402 to rise and extend out of the first inner cavity 501. When injection is needed, rotating the first injection plate 1 causes the corresponding drug tube 4 to extend out of the first sleeve 5, improving visibility. When injection is not needed, rotating the first injection plate 1 causes the connector 6 to return to the horizontal section 503, and the connector 6 descends, causing the second tube section 402 to descend, allowing the drug tube 4 to move into the first inner cavity 501.
[0049] By rotating the first injection plate 1, the drug tube 4 to be injected can extend out of the first sleeve 5, improving identification and reducing operational errors. The movement of the connector 6 within the guide groove 502 ensures the precise extension and retraction of the drug tube 4, improving operational accuracy. Operators only need to rotate the first injection plate 1 to extend and retract the drug tube 4, simplifying the operation process and improving work efficiency. The extension and retraction mechanism of the drug tube 4, combined with the rotation of the first injection plate 1, ensures the correct sequence and dosage of drug injection, improving patient treatment outcomes and safety.
[0050] Furthermore, it also includes: a second sleeve 7, which is disposed on the second injection plate 2 and has a second inner cavity 701, with a second through hole 201 communicating with the second inner cavity 701. The second sleeve 7 has a drug outlet 702, the diameter of which is smaller than the cross-sectional diameter of the second inner cavity 701, and communicates with the second inner cavity 701.
[0051] In this embodiment, when the first injection plate 1 rotates, aligning the first through hole 101 with the second through hole 201, the medication enters the second through hole 201 through the first through hole 101 and then enters the second inner cavity 701. After entering the second inner cavity 701, the medication is discharged through the outlet 702. Because the diameter of the outlet 702 is smaller than the cross-sectional diameter of the second inner cavity 701, the medication experiences some resistance during discharge, ensuring a stable flow of the medication. The medication is stably discharged through the outlet 702 and enters the patient's body.
[0052] The diameter of the dispensing port 702 is smaller than the cross-sectional diameter of the second inner cavity 701, which creates resistance to the discharge of the medication, slowing down the flow rate and ensuring a stable outflow. The smaller dispensing port 702 avoids turbulence during discharge, reduces air bubble formation, and improves the purity and stability of the medication. The smaller dispensing port 702 also allows for better control of the medication flow rate, ensuring accurate dosage for each injection. The dispensing port 702 can be connected via a flexible tube, allowing the medication to be injected into the tube using a syringe. A sealing strip can be added between the first injection plate 1 and the second injection plate 2 to improve sealing.
[0053] Furthermore, it also includes: a hanging part 8, which is connected to the first sleeve 5 and the second sleeve 7, and the hanging part 8 has a hanging opening 801.
[0054] In this embodiment, the hanging part 8 is provided with a hanging port 801, which can be used to hang the entire device on an operating table, hospital bed or other fixed objects, thereby improving the environmental versatility of the device.
[0055] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
