Description

Syringe barrel, syringe and control method thereof Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a syringe barrel, a syringe and a control method thereof. Background Art

[0002] As an auxiliary device in radiological diagnostic and treatment systems, syringes have gradually entered clinical use with the development of large-scale imaging equipment such as CT, MRI, and DSA, as well as iodine and gadolinium ion contrast agents. The basic function of a syringe is to precisely inject a sufficient amount of contrast agent at a set flow rate into the examination area over a specified time period through percutaneous puncture or through existing orifices in the body, thereby enhancing the image of the target area and achieving diagnostic purposes. The syringe is used in conjunction with a syringe barrel (hereinafter referred to as the "syringe"), which contains the contrast agent, contrast agent diluent, or other clinically required liquids.

[0003] Existing syringes have two structures:

[0004] 1. Single opening: The syringe's inlet and injection port share the same opening. This design is often used when a single syringe is used by a single patient. During use, the operator must manually change the contrast agent or saline bottle, repeatedly connect and disconnect the syringe, vial, and tubing, and repeatedly perform venting operations, causing inconvenience in clinical use and wasting contrast agent.

[0005] At the same time, a single opening cannot achieve the dilution of the contrast agent in the same container (here, in the pointer tube), and cannot fully meet the requirements of complex clinical diagnoses such as coronary angiography and ventriculography.

[0006] 2. Dual-port design: The syringe's aspiration port and injection port are two separate openings. This design is often used for reusable syringes, allowing for multiple aspiration and injection, reducing operational complexity and improving efficiency. However, this design cannot accommodate the different dosage forms of contrast agents required for different clinical needs, nor can it achieve contrast agent dilution, resulting in contrast agent waste.

[0007] Therefore, the present invention provides a syringe barrel, a syringe and a control method thereof for injecting a contrast agent. Summary of the Invention

[0017] The control module opens the corresponding control valve when the comparison information module returns true data; otherwise, the control valve remains closed.

[0018] As a preferred technical solution, the liquid stored in the liquid storage device includes contrast agent, physiological saline, water for injection or other required liquids.

[0032] As a preferred technical solution, the mixing treatment method includes vibration, stirring, or rotation.

[0033] As a preferred technical solution, the label information in step S1 includes a control valve code.

[0034] As a preferred technical solution, it further includes S6 starting the piston push rod to extract physiological saline, clean the inner wall of the syringe, and then discharge it to complete the cleaning of the inner wall of the syringe, so as to reduce the concentration error of the solution used next time.

[0035] As a preferred technical solution, the cleaning process of step S6 is performed at least once.

[0036] As a preferred technical solution, the number of the contrast agent pathways is at least 2.

[0037] As a preferred technical solution, the control method of step S2 includes:

[0049] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations. Example

[0050] 1-5 , a syringe barrel includes a barrel body 1 , two or more input ports 3 , and a control valve 5 controlled by a control center module 4 .

[0051] Generally, the syringe body 1 must comply with relevant medical device standards and be equipped with an injection liquid outlet 7 at the end of the syringe body 1. The syringe body 1 is typically made of a transparent or translucent material to allow for intuitive observation of the amount of liquid in the syringe. Furthermore, the syringe body 1 is typically smooth, wear-resistant, and scratch-resistant to ensure safety and accuracy during the injection process.

[0052] The syringe body 1 of the present invention has two or more input ports 3, each of which is provided with a control valve 5 to control the passage of the input port 3, and each of the input ports 3 is connected to a liquid storage device 6 through a pipeline.

[0053] Among them, the control valve 5 is adopted as a mechanical control valve or an electronic control valve. When a mechanical control valve is adopted, the mechanical control valve has a simple structure, high reliability and low maintenance cost. However, for applications that require fine control or complex logic control, an electronic control valve is more suitable. Generally, an electronic control valve is usually equipped with a microcontroller or a microprocessor, which can accurately control the flow and pressure according to the input electrical signal or other sensor signal. The electronic control valve has high sensitivity and response speed, and can realize real-time monitoring and adjustment of fluid characteristics. The control valve 5 in this embodiment is an electronic control valve.

[0054] Generally, the storage capacity of each liquid storage device is 3ml-1000ml. The liquid stored in the liquid storage device 6 includes contrast agent, physiological saline, water for injection or other required liquids.

[0055] In the design of the present invention, when a large-capacity design is adopted, continuous operation of multiple patients can be achieved, reducing the complexity of operation. When a small-capacity design is adopted, small-dose precise injection can be satisfied.

[0056] Taking contrast agent as an example, further, the concentration of contrast agent stored in each liquid storage device 6 is the same. For example, when there are two or even three liquid storage devices 6, 2000ml-3000ml of contrast agent can be stored at one time, which can meet the needs of more patients.

[0057] Taking contrast agent as an example, further, each liquid storage device 6 may store different concentrations of contrast agent. For example, when two liquid storage devices 6 are provided, 500 ml of a 300 concentration (i.e., 300 mg / 100 ml) contrast agent and 500 ml of a 400 concentration (i.e., 400 mg / 100 ml) contrast agent of the same molecular formula may be stored simultaneously for alternating use.

[0058] Taking contrast agent as an example, further, each liquid storage device 6 stores the same type of contrast agent. For example, when there are two liquid storage devices 6, 1000ml-1500ml of contrast agent can be stored at one time, or 500ml of 35% concentration contrast agent and 500ml of 55% concentration contrast agent can be stored at one time, thereby meeting the diverse needs of different patients.

[0059] Taking contrast media as an example, each liquid storage device 6 may store different types of contrast media. For example, if two liquid storage devices 6 are provided, they can simultaneously store 500 ml of 300% concentration contrast media A and 500 ml of 400% concentration contrast media B for alternating use, thus meeting the diverse needs of different patients. Of course, when different types of contrast media are used, additional standardized processing steps are required, such as syringe cleaning.

[0060] Still taking contrast agent as an example, further, when contrast agent dilution is required, contrast agent and saline or water for injection can be simultaneously input into the syringe from the contrast agent storage device and the saline or water for injection storage device according to a set ratio to achieve a predetermined low-concentration contrast agent dilution solution to meet the needs of a specific scanning area or scanning procedure.

[0061] The control center modules in the present invention are respectively connected to the control valves of the contrast agent input ports and control the opening and closing of the control valves.

[0062] In order to more conveniently control the input of contrast agent, the control center module includes:

[0063] Identification information module, used to identify tag information;

[0064] An information comparison module is used to compare the tag information obtained by the identification information module with the preset information of the control valve. If the two information are the same, the return data is true; otherwise, the return data is false;

[0065] The control module opens the corresponding control valve when the comparison information module returns true data; otherwise, the control valve remains closed.

[0066] Generally, the control valve is a one-way valve to prevent the contrast agent from flowing back. Similarly, the injection liquid outlet is provided with a one-way valve to prevent the injection liquid from flowing back.

[0067] In order to achieve the purpose of diluting or flushing the inner wall of the syringe, as shown in FIG5 , the syringe is further provided with a physiological saline input port 8 .

[0068] Specifically, when contrast agent A is to be withdrawn, the control center module controls and opens a control valve on a pipeline connected to a liquid storage device storing contrast agent A. For example, the identification information module identifies tag information and compares the tag information obtained by the identification information module with information preset on the control valve. If the tag information is identical, the control module opens the corresponding control valve; otherwise, the control valve remains closed.

[0069] After the set amount of the liquid medicine is extracted, the control valve is closed, and the piston push rod is pushed to discharge the contrast agent or the mixed liquid out of the syringe to complete the injection.

[0070] The present invention adopts multiple drug suction ports, making it possible for a single syringe to contain different dosage forms of contrast agents or a mixture of contrast agent and physiological saline or other required liquid medicine according to different clinical needs, fully meeting all the needs of clinical diagnosis for contrast agent enhancement and improving work efficiency. Example

[0071] The present invention provides a syringe, comprising the syringe barrel as in Example 1. Example

[0072] 6 , the present invention further provides a method for controlling a syringe, comprising the following steps:

[0073] S1 reads the label information of injection requirements;

[0074] S2 opens the control valve of the corresponding liquid passage according to the tag information;

[0075] S3 starts the piston push rod to extract the corresponding liquid;

[0076] S4: closing the control valve after the set amount of liquid is extracted;

[0077] S5 pushes the piston push rod to discharge the liquid from the syringe.

[0078] The label information in the present invention includes a control valve code. The number of the contrast agent pathways is at least two.

[0079] In step S4 of the present invention, when two or more desired liquids are simultaneously extracted, the liquids are mixed. The mixing method includes vibration, stirring, or rotation. Repeated mixing of the liquids is more conducive to data imaging.

[0080] The specific steps of the present invention also include, S6, starting the piston push rod to extract physiological saline, clean the inner wall of the syringe, and then discharge it to complete the cleaning of the inner wall of the syringe to reduce the concentration error of the contrast agent used next time. For example, the cleaning process of step S6 is performed at least once.

[0081] The control method of step S2 in the present invention includes:

[0082] The tag information is compared with the preset information of the control valve. If the information of the two is the same, the corresponding control valve is opened; otherwise, the control valve remains closed.

[0083] Specifically, taking the extraction of contrast agent A as an example, the control method of the present invention is described again:

[0084] When a patient needs to be injected with contrast agent A, at least one contrast agent channel in the multi-channel injector of the present invention is connected to a contrast agent storage device storing contrast agent A, and a controllable control valve is provided on the contrast agent channel.

[0085] The device reads the label information of the injection request, which contains at least basic information about the contrast agent and a control valve code. When the label information is compared with the preset information of the control valve, if the two information are the same, the corresponding control valve is opened; otherwise, the control valve remains closed. The above-mentioned operation steps should also include saving and recording the comparison results.

[0086] After the control valve is opened, the piston push rod is started to extract the corresponding contrast agent, saline, water for injection or other required liquid medicine. After the set amount of the liquid medicine is extracted, the control valve is closed and the piston push rod is pushed to discharge the contrast agent or mixed liquid out of the syringe to complete the injection.

[0087] In order to facilitate later use and reduce the concentration error of the contrast agent used next time, after the injection is completed, the piston push rod can be started again to extract saline, clean the inner wall of the syringe, and then discharge it to complete the cleaning of the inner wall of the syringe.

[0088] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
