Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and more specifically, to an anesthesia machine with an intake drug concentration detection function. Background Technology

[0002] Anesthesia machines are essential equipment in modern medicine for surgical procedures and other procedures that require controlling the patient's state of consciousness. They deliver a mixture of anesthetic gas and oxygen at a specific concentration to the patient, and through a mechanical circuit, the anesthetic is delivered into the patient's alveoli. After the anesthetic gas partial pressure is formed and diffuses into the blood, it directly inhibits the central nervous system, thereby producing the effect of general anesthesia, putting the patient into a painless and unconscious state so that doctors can safely perform surgery.

[0003] A search revealed a patent with authorization announcement number CN111001067B, which discloses an anesthesia machine including a main unit, a breathing circuit, and an oxygen battery assembly. The breathing circuit is mounted on the main unit, and the oxygen battery assembly includes a housing structure and an oxygen battery cable, with at least a portion of the cable housed within the housing structure. Although this anesthesia machine can house and protect the oxygen battery cable, ensuring stable and safe monitoring of oxygen levels in the breathing circuit, it still has operational drawbacks. After successful anesthesia and muscle relaxation, endotracheal intubation is usually required to maintain oxygen supply and vital signs, especially in general anesthesia for children or obese patients. Due to the unique respiratory anatomy of these patients, anesthetic gases may leak more easily under conventional methods. Furthermore, rapid equipment changes (such as switching from a mask to endotracheal intubation) after successful anesthesia can easily lead to anesthetic gas leakage in the operating room, increasing operational complexity and time costs. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, this utility model provides an anesthesia machine with intake drug concentration detection.

[0005] The technical implementation scheme of this utility model is as follows: an anesthesia machine with an intake drug concentration detector, comprising a base plate and an anesthesia machine body, wherein the base plate is the assembly carrier of the anesthesia machine, the anesthesia machine body is mounted on the base plate, and the anesthesia machine body is used to provide anesthetic gas for surgery; further comprising: a connecting pipe, installed and connected to the anesthetic gas outlet of the anesthesia machine body; a solenoid valve, disposed on the pipe body near the anesthesia machine body; a gas delivery pipe, detachably installed at the gas outlet of the connecting pipe via a snap-fit ​​fitting; a mask, installed and connected to the gas outlet of the gas delivery pipe, wherein a bandage is provided on both sides of the mask for easy wearing; a laryngoscope, disposed through the front of the mask, the laryngoscope being used to assist endotracheal intubation; two guide frames, symmetrically fixed on the front of the mask, the guide frames being located on both sides of the laryngoscope, the guide frames having guide grooves for assisting endotracheal intubation; and a connecting shaft. Fixed to the laryngoscope, the two ends of the laryngoscope's connecting shaft are located in the guide grooves of the guide frame; a sealing ring, made of rubber, is placed on the mask, and the laryngoscope seals against the sealing ring and penetrates the mask; an air suction tube is connected to and installed on the front of the mask via a connector; a miniature air pump is located at the end of the air suction tube, which is used to extract the remaining anesthetic gas in the mask and air delivery tube through the air suction tube. Excess anesthetic gas is extracted before the mask is removed from the patient's face after anesthesia, preventing direct leakage of anesthetic gas into the operating room and causing air pollution. After the mask is worn on the patient's face, anesthetic gas is supplied by the anesthesia machine. After the patient is anesthetized, the miniature air pump directly removes excess anesthetic gas from the mask, and the laryngoscope is used to directly introduce the gas into the patient's cavity wearing the mask. This achieves integrated anesthesia and endotracheal intubation during surgery, saving the need for frequent equipment changes and reducing operational complexity and time costs.

[0006] Furthermore, casters are rotatably mounted at the four corners of the bottom surface of the base plate, and each caster is equipped with a brake. The casters facilitate the transfer and use of the entire anesthesia machine, improving the flexibility and convenience of using the anesthesia machine.

[0007] Furthermore, a tank body is mounted on the base plate via a mounting bracket. This tank body is a container for detecting the concentration of anesthetic gas. The connecting pipe passes through the entire tank body and connects to the gas delivery pipe. The tank body contains: a partition, sealed and separated on the inner wall of the tank body, dividing the tank body into upper and lower compartments, with the connecting pipe located in the upper compartment; an inlet valve, installed on the partition away from the gas delivery pipe, connecting the connecting pipe and the compartment below the partition; an outlet valve, installed on the partition near the gas delivery pipe, also connecting the connecting pipe and the compartment below the partition; and an infrared gas analyzer, located in the lower compartment of the tank body. The system includes: a vacuum pump installed on the outer wall of the tank and connected to the lower compartment of the tank via a pipe; a vacuum pump installed in the lower compartment of the tank to draw the detected anesthetic gas back to the connecting pipe; and a return pipe connecting the vacuum pump and the outlet valve. With the inlet and outlet valves closed, the vacuum pump creates a vacuum in the lower compartment of the tank. The inlet valve is then opened for a period of time, allowing the anesthetic gas input through the connecting pipe to be diverted into the tank for concentration detection. The detected anesthetic gas is then drawn back into the connecting pipe via the return pipe and into the outlet valve by the vacuum pump, thus continuing to provide anesthesia and improving the safety of the surgical anesthesia concentration.

[0008] Furthermore, a target flow meter is installed inside the tank. The target flow meter is located at the outlet of the inlet valve. The target flow meter is used to accurately monitor the anesthetic gas introduced into the tank through the inlet valve, thereby facilitating the doctor to control the anesthetic gas input into the tank to be within a reasonable concentration monitoring range and improving the monitoring accuracy of the anesthetic gas.

[0009] Furthermore, a digital display screen is integrated on the side wall of the tank. The digital display screen is electrically connected to a target flow meter and an infrared gas analyzer. The digital display screen is used to intuitively display the parameters of the anesthetic gas concentration monitoring, so that doctors can intuitively know the current concentration of the anesthetic gas and improve the safety of using anesthetic gas in surgery.

[0010] Furthermore, the mask has a sealing ring at the edge where it fits the patient's face. The sealing ring is used to improve the airtightness of the mask and reduce the risk of leakage of anesthetic gas during anesthesia. The main body of the mask is made of transparent material, which allows doctors to observe the patient's face in real time and understand the patient's physical condition during anesthesia.

[0011] Furthermore, springs are provided between the two guide frames and the connecting shaft. The springs are used to provide the restoring force when the laryngoscope is removed and reset, and to assist the laryngoscope in being easily removed from the patient's larynx after the endotracheal intubation operation is completed.

[0012] Furthermore, the snap-fit ​​component includes a connecting ring, a snap block, and a snap ring. The connecting ring is fixedly installed at the port of the gas supply pipe connecting to the connecting pipe. The snap blocks are symmetrically fixed on both sides of the connecting ring. The snap ring is fixed on the outer wall of the port of the connecting pipe connecting to the gas supply pipe. The snap ring on the pipe wall of the connecting pipe has a notch. The snap blocks on the connecting ring are rotated and snapped into the snap ring, so that the gas supply pipe and the connecting pipe can be easily connected and disassembled.

[0013] Furthermore, a heating element is provided on the pipe body of the connecting pipe near the gas supply pipe. The heating element includes a mounting ring, an electromagnetic coil, and a metal ring. The mounting ring is installed on the outer wall of the connecting pipe, and an electromagnetic coil is provided between the connecting pipe and the mounting ring. A metal ring is provided inside the connecting pipe corresponding to the electromagnetic coil. The electromagnetic coil can heat the metal ring through electromagnetic induction, so that the anesthetic gas flowing through the metal ring in the connecting pipe is appropriately heated to a temperature close to that of the human body, thereby reducing the irritation caused when the anesthetic gas is introduced into the human body.

[0014] Furthermore, multiple oxygen cylinders are installed on the base plate. The oxygen supply port of each oxygen cylinder is connected to an oxygen delivery pipe, which is connected to a connecting pipe. A valve is installed at the connection point between the oxygen delivery pipe and the connecting pipe. The valve is used to open and close the oxygen delivery pipe. If the patient's vital signs are abnormal after anesthesia, the solenoid valve can be closed and the valve of the oxygen delivery pipe can be opened in time after the main body of the anesthesia machine is shut down. This allows the oxygen cylinder to supply oxygen-enriched gas to the connecting pipe through the oxygen delivery pipe, and finally, the oxygen delivery pipe will quickly supply oxygen to the human body, thereby quickly responding to dangerous situations that may occur to the patient during anesthesia and surgery.

[0015] The beneficial effects of this utility model are as follows: 1. By integrating a laryngoscope and a suction tube into the mask, this utility model integrates anesthesia and endotracheal intubation functions into one, reducing the need for frequent equipment changes during surgery, simplifying the operation process and saving time. At the same time, it avoids the risk of anesthetic gas leakage during anesthesia surgery, protecting the operating room environment and the safety of other personnel.

[0016] 2. This utility model can simultaneously monitor the concentration of anesthetic gas through an infrared gas analyzer and a target flow meter inside the tank, and display it intuitively on a digital display screen to ensure the safety and rationality of the anesthetic gas concentration. It is also equipped with a vacuum pump, a suction pump, and a return pipe to realize the reuse of the anesthetic gas concentration after detection and avoid waste.

[0017] 3. This utility model can appropriately heat the anesthetic gas to a temperature close to that of the human body through the heating element on the connecting pipe, thereby reducing the stimulation of the anesthetic gas on the patient. It is also equipped with an oxygen cylinder and oxygen delivery tube, which can quickly supply oxygen in emergency situations, thus improving the ability to deal with abnormal patient signs.

Detailed Implementation

[0027] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0028] Example 1: An anesthesia machine with intake drug concentration detection, such as Figures 2-6 As shown, the device includes a base plate 1 and an anesthesia machine body 2. The base plate 1 serves as the assembly carrier for the anesthesia machine, and the anesthesia machine body 2 is mounted on the base plate 1. The anesthesia machine body 2 is used to provide anesthetic gas for surgery, specifically a mixture of anesthetic drugs and oxygen in a certain proportion. It also includes: a connecting pipe 3, installed and connected to the anesthetic gas outlet of the anesthesia machine body 2; a solenoid valve 4, located near the pipe body of the connecting pipe 3; a gas delivery pipe 6, detachably installed at the gas outlet of the connecting pipe 3 via a snap-fit ​​fitting 10; a mask 7, installed and connected to the gas outlet of the gas delivery pipe 6, with a strap 72 on both sides for easy wearing; a laryngoscope 8, penetrating the front of the mask 7, used to assist in endotracheal intubation; two guide frames 81, symmetrically fixed to the front of the mask 7, located on both sides of the laryngoscope 8, with guide grooves for assisting in endotracheal intubation inside the guide frames 81; and a connecting shaft 82, fixed to the laryngoscope 8. The two ends of the connecting shaft 82 of the laryngoscope 8 are located in the guide groove of the guide frame 81; the sealing ring 84, made of rubber, is set on the mask 7, and the laryngoscope 8 seals against the sealing ring 84 and passes through the mask 7; the suction tube 9 is connected to the front of the mask 7 through the connector 91; the miniature air pump 92 is set at the end of the tube body of the suction tube 9. The miniature air pump 92 is used to extract the remaining anesthetic gas in the mask 7 and the air supply tube 6 through the suction tube 9. Before removing the mask 7 from the patient's face after anesthesia, the excess anesthetic gas is extracted to avoid the anesthetic gas from directly overflowing into the operating room and causing air pollution. After the mask 7 is worn on the patient's face, the anesthetic gas is provided by the anesthesia machine body 2. After the patient is anesthetized, the excess anesthetic gas in the mask 7 is directly extracted by the miniature air pump 92. At the same time, the laryngoscope 8 is used to directly introduce the excess anesthetic gas into the cavity of the patient wearing the mask, thereby achieving an integrated operation of anesthesia and tracheal intubation during anesthesia surgery, saving the need for frequent equipment changes, thus reducing the complexity of operation and time costs.

[0029] like Figure 1 and Figure 2 As shown, casters 100 are rotatably mounted at the four corners of the bottom surface of the base plate 1. Each caster 100 is equipped with a brake. The casters 100 facilitate the transfer and use of the entire anesthesia machine, improving the flexibility and convenience of using the anesthesia machine.

[0030] like Figures 3-5As shown, a sealing ring 71 is provided at the edge of the mask 7 that fits against the patient's face. The sealing ring 71 is used to improve the airtightness of the mask 7 worn by the patient and reduce the risk of leakage of anesthetic gas during anesthesia. The main body of the mask 7 is made of transparent material, which allows the doctor to observe the patient's face in real time and understand the patient's physical condition during anesthesia. Springs 83 are provided between the two guide frames 81 and the connecting shaft 82. The springs 83 are used to provide the restoring force when the laryngoscope 8 is removed and reset, and to assist the laryngoscope 8 in being easily removed from the patient's larynx after the endotracheal intubation operation.

[0031] When using this anesthesia machine, first, use the casters 100 to move the machine flexibly into the operating room. After locking the casters 100 and bringing the machine to a stable stop, begin the anesthesia procedure by placing the mask 7 on the face of the patient lying flat. Secure the patient's head with the straps 72, ensuring the mask 7 fits snugly against the patient's face. The sealing rings 71 at the edges of the mask 7 ensure good airtightness. Then, open the solenoid valve 4. The anesthetic gas containing anesthetic drugs and oxygen is generated by the main body 2 of the anesthesia machine and transmitted through the connecting pipe 3. The anesthetic gas flows through the connecting pipe 3 into the gas delivery pipe 6 and is then delivered to the mask 7. The patient continuously inhales the anesthetic gas inside the mask 7, resulting in anesthesia. Once the patient is successfully anesthetized, the muscles relax. With the patient wearing the mask 7, the surgeon pushes the laryngoscope 8 by overcoming the elasticity of the spring 83 and along the guide groove of the guide frame 81. At this time, due to the sealing ring 84 being in contact with the patient's face... Outside the laryngoscope 8, the laryngoscope 8 is sealed through the mask 7 and slowly inserted into the laryngeal cavity. Guided by the guide frame 81, the laryngoscope 8 can expose the glottis. After seeing the opening between the vocal cords through the laryngoscope 8, the doctor holds the endotracheal tube and, under the guidance of the laryngoscope 8, inserts the endotracheal tube from the right or left side of the patient's mouth, through the glottic cleft into the trachea. After inserting to an appropriate depth and confirming that the tube is in the correct position, the endotracheal tube is fixed. At the same time, under the restoring force of the spring 83, the laryngoscope 8 is slowly withdrawn, thus facilitating the patient to complete the endotracheal intubation operation. In order to ensure the safety of the patient and the operating room, the anesthesia machine body 2 is turned off and the miniature air pump 92 is turned on. The miniature air pump 92 removes excess anesthetic gas from the mask 7 and the air delivery tube 6 after anesthesia is completed through the suction tube 9, avoiding leakage of anesthetic gas when the mask 7 is removed and contaminating the operating room environment, thereby improving the safety and reliability of the surgical operation.

[0032] Example 2: Based on Example 1, such as Figure 1 , Figure 2 and Figure 7As shown, a tank 5 is mounted on the base plate 1 via a mounting base 51. The tank 5 is a container for detecting the concentration of anesthetic gas. A connecting pipe 3 passes through the entire tank 5 and connects to the gas delivery pipe 6. The tank 5 contains: a partition 111, which is sealed and separated on the inner wall of the tank 5, dividing the tank 5 into upper and lower compartments. The connecting pipe 3 is located in the upper compartment; an inlet valve 112, installed on the partition 111 away from the gas delivery pipe 6, which connects the connecting pipe 3 and the compartment of the tank 5 below the partition 111; an outlet valve 113, installed on the partition 111 near the gas delivery pipe 6, which also connects the connecting pipe 3 and the compartment of the tank 5 below the partition 111; and an infrared gas analyzer 114, located in the lower compartment of the tank 5, used to detect the anesthetic gas introduced into the tank 5. The gas concentration; vacuum pump 115, which is installed on the outer wall of tank 5 and connected to the lower compartment of tank 5 through a pipe; vacuum pump 116, which is installed in the lower compartment of tank 5 and is used to pump the tested anesthetic gas back to the connecting pipe 3; return pipe 117, which is connected between vacuum pump 116 and outlet valve 113. After closing the inlet valve 112 and outlet valve 113, the vacuum pump 116 is used to create a vacuum in the lower compartment of tank 5. The inlet valve 112 is opened for a period of time to divert the anesthetic gas input in the connecting pipe 3 into tank 5 for concentration detection. Then, the vacuum pump 116 pumps the tested anesthetic gas through the return pipe 117 into the outlet valve 113, so that the anesthetic gas returns to the connecting pipe 3 to continue providing anesthesia, thereby improving the safety of the surgical anesthesia concentration.

[0033] like Figure 1 , Figure 3 and Figure 7 As shown, a target flow meter 12 is installed inside the tank 5. The target flow meter 12 is located at the outlet of the inlet valve 112. The target flow meter 12 is used to accurately monitor the anesthetic gas introduced into the tank 5 through the inlet valve 112, so that the doctor can control the anesthetic gas input into the tank 5 to be within a reasonable concentration monitoring range, thereby improving the monitoring accuracy of the anesthetic gas. A digital display screen 14 is integrated on the side wall of the tank 5. The digital display screen 14 is electrically connected to the target flow meter 12 and the infrared gas analyzer 114 respectively. The digital display screen 14 is used to intuitively display the parameters of the anesthetic gas concentration monitoring, so that the doctor can intuitively know the current concentration of the anesthetic gas, thereby improving the safety of using anesthetic gas in surgery.

[0034] like Figure 3 , Figure 4 and Figure 8As shown, the snap-fit ​​component 10 includes a connecting ring 101, a snap block 102, and a snap ring 103. The connecting ring 101 is fixedly installed at the port of the gas supply pipe 6 connecting to the connecting pipe 3. The snap block 102 is symmetrically fixed on both sides of the connecting ring 101. The snap ring 103 is fixed on the outer wall of the pipe opening of the connecting pipe 3 connecting to the gas supply pipe 6. The snap ring 103 on the pipe wall of the connecting pipe 3 has a notch. The snap block 102 on the connecting ring 101 is rotated into the snap ring 103 through the notch, so that the gas supply pipe 6 can be easily connected and disassembled with the connecting pipe 3.

[0035] like Figure 3 , Figure 7 and Figure 8 As shown, a heating element 13 is provided on the pipe body of the connecting pipe 3 near the gas supply pipe 6. The heating element 13 includes a mounting ring 131, an electromagnetic coil 132, and a metal ring 133. The mounting ring 131 is installed on the outer wall of the connecting pipe 3. An electromagnetic coil 132 is provided between the connecting pipe 3 and the mounting ring 131. A metal ring 133 is provided inside the connecting pipe 3 at the position corresponding to the electromagnetic coil 132. The electromagnetic coil 132 can heat the metal ring 133 through electromagnetic induction, so that the anesthetic gas flowing through the metal ring 133 in the connecting pipe 3 is appropriately heated to a temperature close to that of the human body, thereby reducing the irritation caused when the anesthetic gas is introduced into the human body.

[0036] like Figure 1 As shown, multiple oxygen cylinders 15 are installed on the base plate 1. The oxygen supply port of the oxygen cylinder 15 is connected to an oxygen supply pipe 16, which is connected to a connecting pipe 3. A valve 17 is installed at the connection point between the oxygen supply pipe 16 and the connecting pipe 3. The valve 17 is used to open and close the oxygen supply pipe 16. When the patient's vital signs are abnormal after anesthesia, after shutting down the main body 2 of the anesthesia machine, the solenoid valve 4 can be closed in time and the valve 17 of the oxygen supply pipe 16 can be opened, so that the oxygen cylinder 15 can supply oxygen-enriched gas to the connecting pipe 3 through the oxygen supply pipe 16, and finally supply oxygen to the human body quickly through the gas supply pipe 6, thereby quickly responding to dangerous situations that occur to the patient during anesthesia and surgery.

[0037] After completing the endotracheal intubation and removing excess anesthetic gas, since the endotracheal tube is still in the patient's mouth, the mask 7 can be removed from the patient's face. Simultaneously, rotate the connecting ring 101 on the inlet tube 6 so that the locking block 102 on the connecting ring 101 aligns with the notch on the outer retaining ring 103 of the connecting tube 3. The inlet tube 6 can then be easily detached from the connecting tube 3. At the same time, reconnect the endotracheal tube inserted into the patient's airway to the connecting tube 3 in a sealed manner. Then, turn on the anesthesia machine body 2 and continue to provide anesthetic gas to actively oxygenate and provide continuous anesthesia for the patient after surgery. Since the inlet valve 112 and outlet valve 113 are closed, first use the vacuum pump 116 to evacuate the sealed container 5 into a vacuum. Then, the inlet valve 112 is opened. When the anesthetic gas enters the connecting pipe 3 inside the tank 5, under the pressure difference between the connecting pipe 3 and the tank 5, the anesthetic gas flows through the inlet valve 112 into the lower compartment of the tank 5. After the inlet valve 112 is opened for a short period of time and then closed, the infrared gas analyzer 114 performs real-time concentration detection of the anesthetic gas in the tank 5 to confirm that the concentration of the anesthetic gas input into the human body meets the preset standard of the current output of the anesthesia machine. Furthermore, when the anesthetic gas enters the tank 5, the target flow meter 12 monitors the gas flow rate to ensure accurate control of the amount of anesthetic gas. Finally, the infrared gas analyzer 114 and the target flow meter 12 transmit the monitored data. The values ​​are transmitted to the digital display screen 14 via electrical signals, where they are displayed intuitively, allowing medical personnel to monitor the status of the anesthetic gas at any time. When the anesthetic gas concentration meets the requirements for continuous anesthesia, the outlet valve 113 is opened and the vacuum pump 116 is used to extract the detected anesthetic gas, which is then returned to the connecting pipe 3 via the return pipe 117 for subsequent anesthesia operations. If the detected anesthetic gas concentration does not meet the requirements, the system can correct it by adjusting the output of the anesthesia machine body 2 or adjusting the opening and closing degree of the solenoid valve 4. Finally, the outlet valve 113 is closed and the vacuum pump 115 is turned on again. If necessary, the tank 5 is evacuated, and then fresh anesthetic gas is introduced. A new round of detection is performed on the anesthetic gas. During continuous delivery of anesthetic gas, the electromagnetic coil 132 heats the metal ring 133 through electromagnetic induction, so that the anesthetic gas passing through here is appropriately heated to close to the human body temperature, thereby reducing the discomfort or irritation that may be caused when the anesthetic gas is introduced into the patient's body. When the patient suddenly has an emergency during the anesthesia procedure, the main body 2 of the anesthesia machine and the solenoid valve 4 are directly shut off, and the valve 17 on the oxygen delivery tube 16 is opened. At this time, through the multiple oxygen tanks 15 installed on the base plate 1, oxygen enrichment can be provided to the patient under anesthesia, so that oxygen supply can be quickly switched when the patient's vital signs become abnormal, maintaining the stability of the patient's vital signs and improving the safety of the anesthesia procedure.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
