Description

TECHNICAL FIELD

[0001] The present application relates to the field of anesthetic quantification, in particular to an anesthetic quantification and delivery device for operating room anesthesia machines. BACKGROUND

[0002] Anesthetics are a class of drugs that temporarily block pain sensation or consciousness by inhibiting the central nervous system or local nerve conduction, allowing patients to be painless, muscle relaxed or unconscious during surgery or medical procedures. According to the range and method of action, they can be divided into general anesthetics (such as propofol, isoflurane, which act on the brain to cause unconsciousness) and local anesthetics (such as lidocaine, bupivacaine, which block local nerve signal conduction). Anesthetics need to be strictly controlled in dosage and usage to avoid risks such as respiratory depression and arrhythmia, and are one of the core tools for modern medical surgery, pain management and intensive care.

[0003] In the prior art, although it can be used, there are defects: the existing operating room anesthetic quantification device lacks precise quantification and liquid leakage prevention functions, resulting in a cumbersome process for extracting anesthetics during surgery, which is prone to errors and affects surgical efficiency. In view of this, we propose an anesthetic quantification and delivery device for operating room anesthesia machines, which solves the above problems. SUMMARY

[0004] The purpose of the present application is to address the problem of lack of precise quantification and liquid leakage prevention function in the background art, which leads to a cumbersome process for extracting anesthetics during surgery, which is prone to errors and affects surgical efficiency. An anesthetic quantification and delivery device for operating room anesthesia machines is proposed.

[0005] The technical solution of the present application: an anesthetic quantification and delivery device for operating room anesthesia machines, comprising a table top, a bottom plate, a box body, a quantification groove and a buffer groove, the bottom plate is fixed on the upper end of the table top, the box body is fixed on the upper end of the bottom plate, the quantification groove is arranged on one side of the box body, the piston one is arranged inside the quantification groove, the piston one is rotatably installed on the upper end of the screw rod, the screw rod is rotatably installed on one end of the upper end of the quantification groove through the mobile frame, the installation frame is arranged on one side of the quantification groove, the height-adjustable lifting frame is single-plugged on the installation frame, and the buffer groove is arranged on the upper end of the lifting frame.

[0006] When the device is in use, the anesthetic can be placed inside the box, and then the button is pressed with the foot to drive the water pump for delivery. The motor is used to drive the screw rod to rotate to adjust the height of the piston 1 inside the quantitative tank. This height can be indirectly measured by an infrared transmitter and an infrared receiver to achieve a quantitative effect. After quantitative measurement, the control valve 1 is opened for delivery. During delivery, the control valve 3 is opened, the control valve 2 is opened, and the piston 2 is displaced to the left by an end distance under the action of water pressure. Then the anesthetic drops from the transmission tube. After the dripping is completed, the control valve 1 is closed, the control valve 3 is closed, and the control valve 2 is opened. The piston 2 returns to its position under the action of the spring, and a negative pressure is formed on the left side of the piston 2. The liquid at the transmission tube mouth is not recycled, so that it will not drip and waste. This device can achieve fast and convenient quantitative and foot-operated drip control effects, and cooperates with the rebound design of piston 2 to realize the function of negative pressure leakage prevention, which has high practicality; integrating quantitative delivery, foot control, negative pressure leakage prevention and height adjustment functions, and using infrared ranging, multi-valve linkage and spring reset mechanisms to achieve accurate quantitative and efficient delivery of anesthetic liquid. Its core advantages lie in the convenience of operation (such as foot buttons, adjustable lifting frames), anti-waste design (negative pressure dripping prevention) and high-precision control (infrared ranging, motor drive), which significantly improve the safety and efficiency of clinical anesthesia and have significant practical value.

[0007] Preferably, a control valve 1 is provided on one side of the lower end of the quantitative tank, and a transmission pipe is provided on one side of the control valve 1. The transmission pipe is plugged into the middle of the lifting frame. The control valve 1 accurately controls the start and stop of the liquid medicine delivery. The transmission pipe cooperates with the lifting frame to achieve height-adjustable dripping to meet the needs of different operating scenarios.

[0008] Preferably, control valve 2 and control valve 3 are provided at the upper end of the transmission pipe, and pipes are connected between control valve 2, control valve 3 and the buffer tank. Multiple valves cooperate to control the direction of liquid flow to ensure one-way delivery of the liquid medicine, avoid residue or backflow, and improve system reliability.

[0009] Preferably, a second piston is provided inside the buffer tank, and a spring is fixed between the right side of the second piston and the inner wall of the buffer tank. The spring drives the second piston to reset and generate negative pressure, which effectively prevents residual liquid from dripping at the mouth of the transmission pipe and reduces waste; the piston height is adjusted by a motor-driven screw rod, and precise quantitative measurement is achieved in combination with infrared ranging; the second piston and the spring design of the buffer tank are used to form negative pressure to prevent the liquid from flowing back and dripping, thereby improving operational convenience and drug utilization.

Limiting holes distributed in a linear array are opened on the surface of the insert plate, and screws are provided on the outer wall of one side of the mounting frame. The screws are threadedly connected to the limiting holes. The screws fix the limiting holes to achieve rapid positioning and flexibly adapt to the drip height requirements of different patients or surgical positions.

[0011] Preferably, a controller is fixed to one side of the upper end of the base plate, and a foot pedal button is provided under the table top. The controller is electrically connected to the foot pedal button. The foot pedal control frees the hands, making it easier for the operator to concentrate on the operation. At the same time, the integrated design simplifies the process.

[0012] Preferably, a bracket is fixed to the lower end of the table top, and a base is fixed to the lower end of the bracket to enhance the overall stability, prevent the equipment from tilting during operation, and ensure safety and reliability.

The upper end of the movable frame is fixed to the motor, and the output shaft of the motor is fixedly connected to the rotation center of the upper end of the screw rod. The guide rail ensures that the screw rod rises and falls smoothly, and the motor accurately controls the piston position, further improving the quantitative accuracy.

[0015] Preferably, an infrared transmitter is provided on the upper end of the piston, and an infrared receiver is provided on the inner wall of the upper end of the quantitative groove. The infrared transmitter and infrared receiver are used for distance measurement. Non-contact measurement avoids contamination and provides real-time feedback of the piston position to ensure accurate quantitative results.
