Description

Technical Field

[0001] This invention relates to the field of anesthesiology equipment technology, and in particular to an auxiliary anesthesia device for obstetric clinical anesthesia. Background Technology

[0002] The work of anesthesiologists in obstetric surgery encompasses multiple aspects, including preoperative assessment, anesthesia administration and management, and postoperative observation. In the clinical stage, anesthesiologists need to be proficient in anesthesia techniques and accurately implement epidural anesthesia, spinal anesthesia, and general anesthesia. Throughout the process, they must monitor the mother's vital signs in real time, including blood pressure, heart rate, respiration, and blood oxygen saturation. They must pay attention to the anesthetic effect and side effects, adjust the anesthesia plan in a timely manner, and take appropriate emergency measures quickly in case of emergencies, such as severe hypotension, allergic reactions, or respiratory depression, to ensure the mother's safety.

[0003] Currently, the entire surgical time is difficult to predict accurately for anesthesiologists, who often need to work continuously for long periods. During surgery, anesthesiologists need to constantly monitor the patient's vital signs such as heart rate, blood pressure, and respiration, and make timely and precise adjustments based on the depth of anesthesia and vital signs to ensure the patient's safe and stable anesthesia state. This requires a high degree of concentration and focus, which can easily lead to mental fatigue. The work of anesthesiologists is complex, including not only performing anesthesia procedures, but also preparing medications and checking equipment before surgery, escorting patients to the post-anesthesia recovery room, and managing post-operative analgesia. In some hospitals with a high volume of surgeries, anesthesiologists are responsible for 7-10 patients a day. Each surgery involves a series of procedures such as drawing medication, preparing breathing lines, pre-operative assessment, setting up monitoring, induction, and intubation. The work pace is fast and the intensity is high, including manual medication drawing and injection, and filling out clinical anesthesia records. Therefore, the work of anesthesiologists is very tiring. To address this, the inventor has proposed an auxiliary anesthesia device for obstetric clinical anesthesia, aiming to minimize the workload of anesthesiologists. Summary of the Invention

In the actual implementation, the state, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0024] The core idea of ​​this invention is to set up a display module, an injection pump, and a main control unit, and to install a camera and a rotating mechanism on the injection pump to enable the camera to capture images of the anesthetic drug label and syringe markings. The industrial control computer then outputs an electronic anesthesia chart including the anesthetic drug name, concentration, injection volume, injection speed, injection time, and medication instructions. This provides convenience for anesthesiologists in the three aspects of manual drug aspiration, drug injection, and filling out the clinical anesthesia record form, thereby reducing the workload of anesthesiologists.

[0025] In some embodiments, such as Figure 1-4As shown, an auxiliary anesthesia device for obstetric clinical anesthesia includes: a display module 100, an infusion pump 200, and a main control unit 300. The infusion pump 200 includes a housing 210, a first drive structure, a pusher 220, a slot 230, a second drive structure 240, a rotating mechanism 250, and a camera 260. The housing 210 is provided with a syringe fixing groove 211 for fixing a syringe 400, and the syringe fixing groove 211 is provided with a slot 230 for fixing a baffle of the syringe 400. For the insertion of the syringe 400 baffle, the slot 230 is a semi-circular groove with a radius larger than that of the syringe 400 baffle, so that the slot 230 allows the syringe 400 baffle to rotate inside. One end of the syringe fixing groove 211 is provided with a pusher 220, which is connected to a first drive structure provided in the housing 210. The first drive structure is used to drive the pusher 220 to move back and forth along the syringe fixing groove 211, and use the pusher 220 to push the injection plunger of the syringe 400 to realize the injection of anesthetic.A camera bracket 261 is mounted on the housing 210, and a camera 260 is mounted on the camera bracket 261. The camera 260 is used to capture images of the anesthetic drug label and syringe markings on the syringe 400. The first drive structure, the camera 260, and the main control unit 300 are electrically connected. The main control unit 300 contains an image processing module, a data processing module, a data entry module, and a data transmission module. The image processing module is configured to: 1) receive the video captured by the camera 260 and extract keyframes containing the complete anesthetic drug label and syringe markings; 2) perform text recognition on the content recorded on the anesthetic drug label and extract the recognized text from the anesthetic drug label. In the data entry module of the main control unit 300, 3) the syringe scale is identified, the key frame and timestamp of the start of operation of the injection pump 200 and the key frame and timestamp of the completion of operation of the injection pump 200 are obtained and feature extraction is performed to obtain the relative position of the injection plunger and the syringe scale, thereby obtaining the pre-injection and post-injection doses of the anesthetic. The injection volume of the anesthetic can be obtained by using the pre-injection and post-injection doses. Then, the injection time is calculated based on the two timestamps. The data processing module reads the injection time and injection volume and calculates the injection speed. In some embodiments, the data entry module is an electronic anesthesia chart. This includes the anesthetic drug name, concentration, injection volume, injection rate, injection time, and a description of the medication administration. The anesthetic drug name and concentration data are obtained by the image processing module from the anesthetic drug label. The injection volume and injection rate are calculated and output by the data processing module. The injection time is the timestamp from the main control unit 300 when the infusion pump 200 administers the injection. The description of the medication administration is filled in by the anesthesiologist using an input module to record the patient's condition at the time of anesthetic drug administration. The input module can be a keyboard input device, a voice-to-text input device, or handwritten after printing. This data is sent to the display via the data transmission module. The main control unit 300 is connected to... A printer can print out the electronic anesthesia chart after surgery for easy record-keeping. In some embodiments, the electronic anesthesia chart also includes the anesthetic drug inventory. Before surgery, the anesthesiologist plans the required anesthetic drugs and the prepared quantities based on the surgical situation, and inputs all this information into the electronic anesthesia chart. During surgery, after the image processing module performs text recognition on the content recorded on the anesthetic drug label, it matches the recognized text with the corresponding anesthetic drug in the electronic anesthesia chart. The anesthetic drug inventory is obtained by subtracting the injection volume from the prepared quantity. If the anesthetic drug inventory is too low, the anesthesiologist can be alerted to retrieve the medication from the pharmacy in advance.

The limit frame 280 is provided with a second driven wheel 253. The elastic telescopic rod 270 is used to drive the second driven wheel 253 to press against the syringe 400 through the limit frame 280. The push head support 254 is rotatably mounted on the push head 220. The push head 220 is movably connected to the injection plunger end of the syringe 400. When installing the syringe 400, simply pull the limit frame 280 outward, then insert the baffle of the syringe 400 into the slot 230, and then release the limit frame 280. The driving wheel 251, the first driven wheel 252, and the second driven wheel 253 together hold the empty cylinder of the syringe 400.
