Abstract
Description
Technical Field
[0001] The invention relates to the technical field of medical equipment, in particular to an indoor gas purification device for anesthesia. Background Art
[0002] In the field of modern anesthesia medicine, anesthesiologists often use anesthetics such as isoflurane and enflurane to perform general or local anesthesia on patients. These anesthetics have the characteristics of a low boiling point. In clinical applications, they are usually first evaporated into a gas state through an evaporator and then delivered to the patient's body together with oxygen, thereby effectively reducing the pain suffered by the patient during the operation.
[0003] However, during the anesthesia process, when the patient inhales anesthetic gas with the help of a breathing mask, the anesthetic gas cannot be completely absorbed. The gas exhaled by the patient is a mixture of carbon dioxide and anesthetic gas. Since the operating room environment is relatively closed, these mixed gases can easily diffuse into the entire operating room space. The medical staff in the operating room are in such an environment for a long time, and they will inevitably be frequently exposed to these escaped anesthetic gases. Anesthetic gas poses many potential threats to the health of medical staff.
[0004] To this end, the present invention provides a gas purification device for anesthesia room to solve the above problems. Summary of the invention

[0013] Preferably, the treatment block is composed of an outer breathable gauze and an inner molecular sieve, and the molecular sieve is in the shape of small solid particles.
[0014] Beneficial Effects
[0015] The present invention provides an indoor gas purification device for anesthesia. Compared with the prior art, it has the following advantages:
[0016] Beneficial effects:
[0017] 1. The indoor gas purification device for anesthesia uses a fixing belt to tightly buckle the mask on the outside of the patient's mouth and nose, and cooperates with a sealing gasket to ensure that the gas inside the mask will not flow out from the external gap, and the first one-way valve ensures that the gas in the mask will not flow back into the trachea, ensuring the sealing and effectiveness of the mask, making the anesthesia process more stable and safe.
[0018] 2. The indoor gas purification device for anesthesia, the processing components on both sides of the mask can process the mixed gas exhaled by the patient. The exhaled gas enters the processing box through the connecting hole and the outer tube. The processing block in the processing box uses a molecular sieve to selectively adsorb anesthetic gas, allowing other gas molecules such as carbon dioxide to pass through, effectively absorbing the anesthetic in the gas, preventing it from spreading to the operating room and endangering the health of medical staff, thereby ensuring the safety of the operating room environment.
[0019] 3. In the indoor gas purification device for anesthesia, the electrochemical sensor in the exhaust pipe can detect the anesthetic content in the exhaust gas based on chemical reactions. When the content exceeds the preset value, it can promptly prompt that the molecular sieve in the processing block has reached the upper limit of absorption. At this time, the connection direction of the one-way solenoid valve is changed by the external controller, which is convenient for rotating the sealing cover to take out the threaded cylinder, and then replace the processing block, ensuring the continuous and effective treatment of the anesthetic, which not only guarantees the treatment effect, but also facilitates the maintenance and management of the equipment, and improves the overall reliability and practicality of the device.
[0020] 4. The indoor gas purification device for anesthesia has different numbers of molecular sieves in the left and right processing blocks. When the molecular sieve on one side is used up and replaced, the other side can still absorb anesthetics normally, ensuring that the equipment can continue to absorb anesthetics normally during the replacement of the molecular sieve, without affecting the treatment effect of the anesthetic gas, ensuring that the anesthetic gas in the operating room environment can be effectively purified.

[0030] The present application is further described in detail below through drawings and examples.
[0031] Reference Figures 1 to 6 The embodiment of the present application provides an indoor gas purification device for anesthesia, comprising a mask 1, a processing assembly 2 is arranged on the outside of the mask 1, the processing assembly 2 comprises a connecting block 21, the connecting block 21 is fixedly installed inside the mask 1, an outer tube 23 is fixedly installed on the outside of the connecting block 21, a connecting hole 22 is opened on the inner end of the outer tube 23, the connecting hole 22 connects the inside of the connecting block 21 with the inside of the mask 1, the outer tube 23 is connected to the inside of the connecting block 21, a processing box 25 is fixedly installed on the outer end of the outer tube 23, and a processing block 28 is fixedly installed inside the processing box 25. A fixing belt 3 is fixedly installed on the back of the mask 1, and the fixing belt 3 is an elastic belt. A sealing pad is fixedly installed on the outer edge of the mask 1.
[0032] A connecting pipe 4 is fixedly installed on the front of the mask 1, a first one-way valve 5 is fixedly installed on the outside of the connecting pipe 4, an air intake pipe 6 is fixedly installed at the inlet of the first one-way valve 5, the connecting pipe 4 is connected with the outlet of the first one-way valve 5, the connection direction of the first one-way valve 5 is from the air intake pipe 6 to the inside of the connecting pipe 4, and the connecting pipe 4 is connected with the inside of the mask 1.
[0033] In this embodiment, when the device is in use, the mask 1 is buckled on the outside of the patient's nose and mouth through the fixing belt 3, and the mask 1 is fitted to the patient's face through the sealing pad on the outside of the mask 1 to ensure that the gas inside the mask 1 will not flow out through the external gap of the mask 1. The external anesthetic mixed with oxygen enters the connecting pipe 4 through the inlet pipe 6, and then enters the inside of the mask 1 through the connecting pipe 4 to achieve anesthesia for the patient. During anesthesia, the first one-way valve 5 is used to ensure that the gas inside the mask 1 will not flow back into the inlet pipe 6, thereby ensuring the use effect of the mask 1.
[0034] Reference Figures 1 to 6In one aspect of this embodiment, a threaded barrel 29 is screwed inside the outer end of the processing box 25, a sealing cover 26 is fixedly installed on the outer end of the threaded barrel 29, an anti-slip pattern is provided on the outer side of the sealing cover 26, and a sealing gasket is fixedly installed at the connection between the sealing cover 26 and the processing box 25. A discharge pipe 27 is fixedly installed on the outer end of the sealing cover 26, an electrochemical sensor 210 is fixedly installed inside the discharge pipe 27, a through hole is provided inside the sealing cover 26, and the discharge pipe 27 is connected to the inside of the processing box 25 through the through hole. The electrochemical sensor 210 and the one-way solenoid valve 24 are both electrically connected to the external controller.
[0035] The left and right sides of the mask 1 are provided with processing components 2, which are located outside the middle connecting pipe 4 and the first one-way valve 5, and close to the edge of the mask 1. The processing block 28 is composed of an outer breathable gauze and an inner molecular sieve, and the molecular sieve is in the shape of small solid particles.
[0036] In this embodiment, when the exhaled gas is mixed with the anesthetic, it will be discharged into the inside of the connecting block 21 through the connecting hole 22, and then enter the inside of the processing box 25 through the outer tube 23. The anesthetic in the gas is absorbed by the molecular sieve inside the processing block 28 inside the processing box 25. During the absorption, the gas passes through the external gauze and enters the internal molecular sieve to be absorbed by the molecular sieve. The absorbed gas passes through the gauze and is discharged from the discharge pipe 27, so that the anesthetic in the exhaust gas is absorbed and processed, thereby solving the problem of the mixed gas of carbon dioxide and anesthetic gas exhaled by the patient, which will diffuse into the operating room and threaten the health of medical staff. The molecular sieve is a silicate crystal with a regular microporous structure, which can selectively adsorb anesthetic gas according to molecular size and polarity. Its pore size matches the molecular size of anesthetic gas, and can intercept anesthetic gas molecules like a "sieve" while allowing other gas molecules such as carbon dioxide to pass through.
[0037] When the gas passes through the outer tube 23, the one-way solenoid valve 24 ensures that the gas can be discharged from the inside of the outer tube 23 without flowing back into the mask 1, and the electrochemical sensor 210 inside the discharge tube 27 detects the anesthetic content in the discharged gas. The electrochemical sensor 210 detects the gas concentration based on the current or potential change generated by the chemical reaction. For the detection of anesthetics, when the anesthetic gas molecules diffuse to the sensitive electrode surface of the sensor, an oxidation or reduction reaction will occur. The chemical reaction on the electrode surface will cause electron transfer, and the magnitude of the generated current is proportional to the concentration of the anesthetic gas. When the anesthetic content exceeds the predetermined value, it means that the molecular sieve inside the processing block 28 has reached the upper limit of absorption and needs to be replaced. At this time, the one-way solenoid valve 24 is energized by the external controller, thereby changing the connection direction of the one-way solenoid valve 24. At this time, the internal gas cannot be discharged through this one-way solenoid valve 24. At this time, the threaded barrel 29 can be driven to rotate by rotating the sealing cover 26, and the threaded barrel 29 can be taken out. After taking it out, the processing block 28 is taken out and replaced with a new processing block 28, thereby ensuring the treatment effect of the anesthetic;
[0038] The number of molecular sieves contained in the left and right processing blocks 28 is different. The number of molecular sieves on the left is at least 1.5 times that of the right molecular sieve. When the right electrochemical sensor 210 detects that the molecular sieve on the right is used up, there is still one-third of the molecular sieves unused inside the left molecular sieve. At this time, when the molecular sieve on the right is replaced, the molecular sieve on the left can absorb the anesthetic normally. After the molecular sieve on the right is replaced, both sides continue to absorb the anesthetic at the same time. After that, the molecular sieve on the left will be used up. At this time, the molecular sieve on the right can continue to absorb the anesthetic, thereby ensuring that when the molecular sieve is replaced, the equipment can absorb the anesthetic normally without affecting the absorption effect of the anesthetic.
[0039] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.
[0040] Working principle: When the device is in use, the mask 1 is buckled on the outside of the patient's nose and mouth through the fixing belt 3, and the mask 1 is fitted on the patient's face through the sealing pad on the outside, ensuring that the gas inside the mask 1 will not flow out through the external gap of the mask 1. The external anesthetic mixed with oxygen enters the connecting pipe 4 through the air inlet pipe 6, and then enters the mask 1 through the connecting pipe 4 to achieve anesthesia for the patient. During anesthesia, the first one-way valve 5 is used to ensure that the gas inside the mask 1 will not flow back into the air inlet pipe 6, ensuring the use effect of the mask 1. The exhaled gas mixed with the anesthetic will be discharged into the connecting block 21 through the connecting hole 22 when discharged, and then enter the processing box 25 through the outer tube 23. The molecular sieve inside the block 28 absorbs the anesthetic in the gas. During the absorption, the gas passes through the external gauze and enters the internal molecular sieve to be absorbed by the molecular sieve. The absorbed gas passes through the gauze and is discharged from the discharge pipe 27, so that the anesthetic in the discharged gas is absorbed and processed, thereby solving the problem of the mixed gas of carbon dioxide and anesthetic gas exhaled by the patient, which will diffuse into the operating room and threaten the health of medical staff. The molecular sieve is a silicate crystal with a regular microporous structure. It can selectively adsorb anesthetic gas according to the molecular size and polarity. Its pore size matches the molecular size of the anesthetic gas, and can intercept the anesthetic gas molecules like a "sieve" while allowing other gas molecules such as carbon dioxide to pass through.
[0041] When the gas passes through the outer tube 23, the one-way solenoid valve 24 ensures that the gas can be discharged from the inside of the outer tube 23 without flowing back into the mask 1, and the electrochemical sensor 210 inside the discharge tube 27 detects the anesthetic content in the discharge gas. The electrochemical sensor 210 detects the gas concentration based on the current or potential change generated by the chemical reaction. For the detection of anesthetics, when the anesthetic gas molecules diffuse to the sensitive electrode surface of the sensor, an oxidation or reduction reaction will occur. The chemical reaction on the electrode surface will cause electron transfer, and the magnitude of the current generated is proportional to the concentration of the anesthetic gas. When it is detected that the anesthetic content exceeds the predetermined value, it means that the molecular sieve inside the processing block 28 has reached the absorption upper limit and needs to be replaced. At this time, the one-way solenoid valve 24 is energized by the external controller to change the connection direction of the one-way solenoid valve 24. At this time, the internal gas cannot pass through this one-way solenoid valve. The solenoid valve 24 is discharged. At this time, the threaded barrel 29 can be driven to rotate by rotating the sealing cover 26 to take out the threaded barrel 29. After taking it out, the processing block 28 is taken out and replaced with a new processing block 28, thereby ensuring the treatment effect of the anesthetic; the number of molecular sieves contained in the left and right processing blocks 28 is different. The number of molecular sieves on the left is 1.5 times the number of molecular sieves on the right. When the right electrochemical sensor 210 detects that the molecular sieve on the right is used up, there is still one-third of the molecular sieves unused inside the left molecular sieve. At this time, when the molecular sieve on the right is replaced, the molecular sieve on the left can absorb the anesthetic normally. After the molecular sieve on the right is replaced, both sides continue to absorb the anesthetic at the same time. After that, the molecular sieve on the left will be used up. At this time, the molecular sieve on the right can continue to absorb the anesthetic, thereby ensuring that when the molecular sieve is replaced, the equipment can absorb the anesthetic normally without affecting the absorption effect of the anesthetic.
