Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to an anesthesia tube with intelligent flow control. Background Technology

[0002] Anesthesia generally refers to a reversible inhibition of the central and / or peripheral nervous systems produced by drugs or other methods. The main characteristic of this inhibition is the loss of sensation, especially pain. It is also a science that uses the basic theories, clinical knowledge and techniques of anesthesia to eliminate surgical pain, ensure patient safety and create favorable conditions for surgery.

[0003] During anesthesia, flow control is crucial to prevent excessive flow from causing adverse effects on the patient. Current flow control devices for anesthesia tubing are generally similar to those for intravenous infusion tubing, using plastic components to compress the tubing and thus alter the flow rate. However, if the flow control device is accidentally impacted, the rollers can easily slip, changing the flow control and potentially threatening the patient's vital signs. Therefore, the reliability of these devices is low. Furthermore, existing flow control devices rely on manual control by doctors, which is susceptible to human error and individual differences in experience, making it difficult to achieve highly precise flow rate control. In situations where strict dosage requirements are necessary, this can easily lead to medical risks such as excessive or insufficient anesthesia. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Example 1

[0027] An embodiment of this utility model provides an anesthesia tube with intelligent flow control, such as... Figures 1-5 As shown, the system includes a control block 1, which houses a PCB control center. A pipe 9 is mounted on the control block 1, and a solenoid valve 6 and a flow display sensor 8 are mounted on the pipe 9. A push frame 3 is also detachably connected to the control block 1. An anesthesia canister 4 and a linear drive 14 are mounted inside the push frame 3. The linear drive 14 is used to push the liquid in the anesthesia canister 4. The other end of the anesthesia canister 4 is connected to the pipe 9. A mechanical flow limiting component 7 is also mounted on the pipe 9. The PCB control center, solenoid valve 6, flow display sensor 8, and linear drive 14 are electrically connected.

[0028] The working principle and beneficial effects of the above technical solution are as follows: The linear drive 14 is started under the control of the PCB control center, pushing the liquid medicine in the anesthetic canister 4, so that the liquid medicine is transported through the pipe 9 (the pushing speed, i.e. the flow rate value can be preset according to those skilled in the art). When the liquid medicine flows through the pipe 9, the flow display sensor 8 monitors the flow rate of the liquid medicine in real time and feeds back the flow rate information to the PCB control center. The PCB control center compares and analyzes the preset flow rate value with the actual flow rate value fed back, and then controls the opening degree of the solenoid valve 6.

[0029] Through the coordinated operation of the PCB control center, solenoid valve 6, flow display sensor 8, and linear drive 14, the PCB control center receives signals from the flow display sensor 8 and controls the pushing speed and force of the linear drive 14 as well as the on / off state of the solenoid valve 6. This achieves precise control over the output of the anesthetic solution in the anesthesia canister 4, effectively preventing flow loss due to unexpected external factors and greatly improving the stability and reliability of flow control during device use. It also achieves high-precision control of the anesthetic solution flow rate, effectively preventing situations such as excessive or insufficient anesthesia, and providing stronger protection for patient safety.

[0030] Example 2

[0031] Based on the above embodiment 1, as follows Figures 1-2As shown, a cavity is provided inside the control block 1, and a PCB control center is provided inside the cavity. The pipe 9 passes through the cavity. An opening is provided on one side of the control block 1, and the push frame 3 is detachably connected to the opening.

[0032] Preferably, one side of the push frame 3 is provided with an opening two, a linear drive 14 is fixedly provided on the inner wall of the push frame 3, the output end of the linear drive 14 is fixedly connected to the push block 15, the anesthesia canister 4 is provided with an opening three, a sealing plate 13 is slidably provided in the opening three, and the sealing plate 13 is in contact with the push block 15.

[0033] Preferably, the anesthesia container 4 is also provided with a through groove, and a rubber pad 12 is provided in the through groove. An insertion rod 2 is connected through the pipe 9. The insertion rod 2 is provided with several channels, and the insertion rod 2 extends into the anesthesia container 4 through the rubber pad 12.

[0034] The rubber gasket 12 serves as a seal to prevent leakage of the medicine, similar to the rubber stopper on an infusion bottle.

[0035] The working principle and beneficial effects of the above technical solution are as follows: First, the anesthesia canister 4 is placed into the push frame 3. Then, the sealing plate 13 contacts the push block 15. After that, the push frame 3 is detachably connected to the control block 1 through the opening 1, which facilitates the maintenance or replacement of the anesthesia canister 4. At this time, the insertion rod 2 on the pipe 9 will pass through the rubber pad 12 and extend into the anesthesia canister 4. Then, through the PCB control center, the linear drive component 14 is started, the push block 15 moves, and the sealing plate 13 will exert pressure on the liquid medicine in the anesthesia canister 4, so that the liquid medicine flows into the pipe through the channel on the insertion rod 2. The above structure is simple, convenient to use, and can quickly replace the anesthesia canister 4, making it highly practical.

[0036] Example 3

[0037] Based on the above embodiments 1-2, such as Figure 1 As shown, a conveying pipe 10 is also connected through the pipe 9.

[0038] Preferably, a flow meter 11 is installed inside the pipe 9, and the flow meter 11 is electrically connected to the flow display sensor 8.

[0039] The beneficial effects of the above technical solution are as follows: the flow rate of the liquid can be seen on the flow display sensor 8 through the flow meter 11 in the pipeline 9, and the flow information can also be fed back to the PCB control center, with better accuracy and more obvious results.

[0040] Example 4

[0041] Based on the above embodiment 1, as follows Figure 1 , Figures 3-5As shown, the pipe 9 includes a second rigid pipe 25, a flexible pipe 24 and a first rigid pipe 26. The second rigid pipe 25, the flexible pipe 24 and the first rigid pipe 26 are connected in a continuous manner. The first rigid pipe 26, the flexible pipe 24 and the second rigid pipe 25 are arranged sequentially along the direction of liquid flow. A solenoid valve 6 is installed on the first rigid pipe 26 and a flow display sensor 8 is installed on the second rigid pipe 25.

[0042] Preferably, the mechanical flow limiting component 7 includes a fixed frame 16, on which a square groove 23 is provided, and the square groove 23 is fixedly connected to the first rigid pipe 26 and the second rigid pipe 25.

[0043] Preferably, a push box 17 is symmetrically fixed inside the fixed frame 16, a push plate 18 is slidably arranged inside the push box 17, a return spring 19 is fixedly arranged on the side of the push plates 18 that are far apart from each other, a push rod 22 is fixedly arranged on the side of the push plates 18 that are close to each other, the push rod 22 slides out of the push box 17, a pressure plate 21 is arranged on the side of the push rod 22 that is close to each other, and the pressure plate 21 cooperates with the hose 24.

[0044] Preferably, the lower ends of the two push boxes 17 are connected by a T-shaped tube 20, the lower end of the T-shaped tube 20 extends into a fixing frame 16, the lower end of the T-shaped tube 20 is detachably connected to an air tube 27, and the lower end of the air tube 27 is connected to an airbag 5.

[0045] Among them, a hole is opened on the side wall of the push box 17 that is far apart from each other, and a sealing plug (such as...) is inserted into the hole. Figure 3 As shown, when the pressure plate 21 needs to be reset, the sealing plug is opened so that the pressure box 17 is the same as the external air pressure, so that the pressure plate 18 is reset under the action of the reset spring 19.

[0046] The working principle and beneficial effects of the above technical solution are as follows: When the solenoid valve 6 malfunctions or when it is necessary to make coarse adjustments to the flow rate in the pipeline 9, first connect the air tube 27 and the air bag 5 to the T-shaped tube 20, then squeeze the air bag 5. The gas in the air bag 5 enters the T-shaped tube 20 through the air tube 27, and the gas then enters the push box 17, which increases the air pressure in the push box 17. This causes the push plate 18 to slide in the push box 17, and the return spring 19 is stretched, generating elastic force. The push plate 18 drives the push rod 22 to slide, and the two pressure plates 21 move closer to each other. The pressure plates 21 will squeeze the hose 24. The greater the degree of squeezing, the smaller the flow rate of the medicine in the hose 24; conversely, the smaller the degree of squeezing, the larger the flow rate.

[0047] Flow rate adjustment is achieved by squeezing the airbag 5. This manual operation method is simple and intuitive, requiring no complex electronic equipment or professional operating skills. In emergencies or when the electronic control system malfunctions, medical staff can quickly adjust the drug flow rate by squeezing the airbag 5 to ensure the safety of the anesthesia process; it also allows for coarse flow rate adjustment. This provides a basic framework for subsequent precise flow control by the PCB control center in conjunction with the solenoid valve 6 and flow display sensor 8, enhancing both safety and practicality.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
