Description

Technical Field

[0001] This utility model relates to a syringe device that integrates pressure monitoring and identification, belonging to the field of medical device technology. Background Technology

[0002] In modern medicine, precise drug injection is crucial. Taking medical diagnostic imaging technologies such as angiography and enhanced CT scans as examples, high-pressure contrast injectors must precisely and stably deliver contrast agents into the human vascular system to obtain clear and accurate images. In intravenous bolus injections, vaccine administration, and high-precision drug delivery, accurate control of injection pressure and drug information is equally indispensable. However, most injectors currently on the market are mechanical, which has many drawbacks.

[0003] First, existing syringes cannot monitor the pressure during drug injection in real time. In actual injection, if the pressure is too high, it may damage the patient's blood vessels and tissues, such as causing serious consequences like blood vessel rupture and tissue necrosis; if the pressure is too low, the drug may not be able to reach the target site smoothly, affecting the treatment effect.

[0004] Secondly, existing syringes lack the automatic ability to identify the type, batch, or usage status of the medication contained within. This can easily lead to medication errors in large-scale medical procedures, such as routine injections in hospitals and vaccination campaigns. For example, mixing different types of medications or using expired or deteriorated medications poses a significant safety hazard to patients' health and lives.

[0005] Third, traditional injection pressure detection methods typically rely on external devices or complex integrated sensors. This not only increases equipment costs and operational complexity, but also hinders the widespread adoption and application of this method for single-use devices. The complex structure and high cost significantly increase the price of disposable syringes, which contradicts the principle of rational use of medical resources.

[0006] Fourth, existing syringes face difficulties in connecting with electronic systems and lack intelligent features. In today's rapidly developing medical information age, the inability to effectively connect with electronic systems means that automated management, analysis, and traceability of injection data are difficult to achieve. Medical staff cannot obtain key information during the injection process in a timely manner, which also hinders hospitals from integrating and utilizing medical data, thereby affecting the quality and efficiency of medical services. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model provides a syringe device that integrates pressure monitoring and identification, enabling real-time detection of injection pressure and identification of the drug without altering existing injection operation habits, thus facilitating clinical monitoring, injection control, and data traceability.

[0008] The technical solution adopted by this utility model to solve its technical problem is:

[0009] A syringe device integrating pressure monitoring and identification includes a plunger and a piston. A pressure sensor module is provided on one side of the plunger, and the pressure sensor module abuts against the piston. An identification module and a data communication module are provided on the other side of the plunger. The identification module is used to identify the syringe's identity, drug type, and production batch. The data communication module is used to synchronously transmit pressure data and identification information to a reading device.

[0010] Preferably, it also includes an injection cylinder, and the piston is sleeved inside the injection cylinder.

[0011] Preferably, the end of the push rod is provided with a column, and a retaining plate is provided on the outer periphery of the column.

[0012] Preferably, a groove corresponding to the cylinder is provided on one side of the piston, and two slots corresponding to the card plate are provided on both sides of the inner wall of the groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The pressure sensor module is highly integrated with the overall structure of the syringe, eliminating the need for additional complex installation steps. The integrated assembly can be completed during the production process. This not only does not affect the normal injection operation of the syringe, but also makes it no different from the traditional syringe for medical staff, reducing the learning cost.

[0015] It can achieve real-time or periodic injection pressure data collection and monitoring. Medical staff can check the pressure data at any time during the injection process, adjust the injection force in time, avoid harm to patients due to abnormal pressure, and improve the safety and accuracy of injection.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3 This utility model provides a technical solution:

[0023] like Figure 2 As shown, a syringe device integrating pressure monitoring and identification includes a plunger 1 and a piston 2. A pressure sensor module 5 is provided on one side of the plunger 1, and the pressure sensor module 5 abuts against the piston 2. An identification module 7 and a data communication module 8 are provided on the other side of the plunger 1.

[0024] When medical staff push the push rod 1, the forward axial thrust of the push rod 1 is transmitted to the piston 2. The pressure sensor module 5 can collect this axial thrust in real time. Since there is a certain correspondence between the axial thrust and the pressure in the drug solution during the injection process, the change in the pressure in the drug solution can be indirectly obtained by monitoring the axial thrust. The pressure sensor module 5 adopts a high-precision and miniaturized design, and has the characteristics of fast response speed and high sensitivity, which can accurately capture the small changes in pressure.

[0025] The identification module 7 uses NFC chip technology. This NFC chip stores a wealth of information, including syringe identity, drug type, production batch, etc. Through NFC reading devices, medical staff can quickly and accurately obtain this information to achieve unique identification of each syringe and its internal drug, providing strong support for medical management and traceability.

[0026] The function of the data communication module 8 is to synchronously transmit the pressure data collected by the pressure sensor module 5 and the identity information stored in the identity recognition module 7 to the reading device, such as the main control unit, mobile terminal, medical information system, etc. The data communication module 8 can use wireless communication technologies such as Bluetooth and Wi-Fi to ensure the stability and timeliness of data transmission, so that medical staff can obtain and process relevant information at any time.

[0027] like Figure 1 As shown, it also includes an injection cylinder 9, and the piston 2 is sleeved inside the injection cylinder 9.

[0028] Specifically, the syringe 9 and piston 2 adopt a traditional structural design. The syringe 9 is used to contain the liquid medicine. Its internal space is cylindrical and has a certain volume scale, which makes it easy for medical staff to accurately read the dosage of the liquid medicine. The piston 2 is tightly fitted inside the syringe 9 and can slide freely inside the syringe 9. Under the push of the push rod 1, it realizes the function of pushing out the liquid medicine in the syringe 9. Medical staff hold the push rod 1 and apply a pushing force to drive the piston 2 to move inside the syringe 9, thereby pushing out the liquid medicine.

[0029] like Figure 3 As shown, the end of the push rod 1 is provided with a column 3, and the outer periphery of the column 3 is provided with a retaining plate 4. The design of the column 3 and the retaining plate 4 facilitates the connection and cooperation between the push rod 1 and the piston 2, making the two more stable and reliable during the pushing process. It also facilitates the recycling and utilization of the pressure sensor module 5, the identification module 7 and the data communication module 8 on the column 3 after use.

[0030] Furthermore, a groove corresponding to the column 3 is provided on one side of the piston 2, and two slots 6 corresponding to the card plate 4 are provided on both sides of the inner wall of the groove.

[0031] The workflow of this embodiment is as follows: Medical personnel retrieve the syringe device from the medical supplies storage area. At this time, the syringe is pre-filled with medication. Using an NFC reader, they approach the identification module 7 to read the information in the identification module 7, confirming whether the medication type, production batch, etc., are correct, and simultaneously checking the expiration date and integrity of the syringe. The medical personnel hold the plunger 1 and correctly insert the syringe needle into the patient's injection site, pushing the plunger 1. As the plunger 1 moves forward, the column 3 and the retaining plate 4 drive the piston 2 to slide smoothly within the syringe 9, ejecting the medication. At the same time, the pressure sensor module 5 collects the axial thrust transmitted from the plunger 1 to the piston 2 in real time and transmits the pressure data to the data communication module 8. The data communication module 8 synchronously transmits the pressure data and the identification information in the identification module 7 to the connected reader. Devices, such as hospital medical information systems or mobile terminals for medical staff, allow medical staff to view injection pressure data in real time, ensuring a safe and smooth injection process. After injection, the used syringe is properly disposed of according to medical waste disposal regulations. Since the identification module 7 records the syringe usage information, this information is transmitted and stored in the medical information system, facilitating subsequent medical data statistics, analysis, and traceability. It should be noted that in actual production and use, the syringe device of this invention should undergo strict quality inspection and performance testing in accordance with relevant medical device production standards and quality control specifications to ensure its safety and reliability. At the same time, the use of the data communication module 8 should comply with relevant information security regulations and standards to protect the patient's privacy information from being leaked.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
