Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a novel carbon dioxide absorber. Background Art

[0002] During the perioperative period for patients undergoing general anesthesia and endotracheal intubation, or those requiring endotracheal intubation for ventilation, exhaled carbon dioxide is effectively absorbed, reducing the partial pressure of exhaled carbon dioxide, preventing hypercapnia, respiratory acidosis, and other internal environmental disturbances, thereby avoiding acute or chronic carbon dioxide poisoning. Severe acute poisoning can paralyze the respiratory center within seconds, leading to rapid breathing and sudden death. Some patients may initially experience dizziness, palpitations, convulsions, coma, and shock. Severe poisoning can worsen, with symptoms such as vomiting, coughing up white or bloody frothy sputum, incontinence, convulsions, and limb stiffness. Death can result from respiratory and circulatory failure. Chronic poisoning: Prolonged exposure to low carbon dioxide concentrations can cause dizziness, difficulty concentrating, mental confusion, and memory loss.

[0003] With the advent of precision medicine, monitoring of the patient's exhaled carbon dioxide partial pressure (PCoP) is essential throughout the intubation process. Effective CO2 absorption is crucial for maintaining the PCoP value within the normal range. Currently, some manufacturers use CO2 inhalation devices that lack anti-detachment devices on both ends of the connector. This makes it easy for the tube to become detached and difficult to detect. Multiple connections increase wear on the anesthesia machine connector, causing inconvenience in clinical use.

[0004] Therefore, those skilled in the art provide a novel carbon dioxide absorber to solve the problems raised in the above background technology. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1 - Figure 8 As shown, this embodiment provides a novel carbon dioxide absorber, comprising an upper box body 1, and further comprising:

[0031] The lower box body 2 is fixedly connected to the interior of the upper box body 1 by screw threads;

[0032] The air inlet pipe 3 is fixedly installed inside the upper box body 1, and the air outlet pipe 4 is fixedly installed inside the lower box body 2. The air inlet pipe 3 and the air outlet pipe 4 are both provided with a guide tube 6;

[0033] The mounting ring 7 is fixedly connected to the outside of the conduit 6. The outsides of the air inlet pipe 3 and the air outlet pipe 4 are fixedly connected with positioning rings 9. The insides of the two positioning rings 9 are provided with guide grooves for the movement of the mounting ring 7.

[0034] A fixing assembly is provided outside the positioning ring 9 and is used to fix the positioning ring 9 and the mounting ring 7;

[0035] Alarm components, respectively provided on the outside of the air inlet pipe 3 and the air outlet pipe 4, and used to sound an alarm when the conduit 6 is detached;

[0036] The sterilizing filter 12 is located between the upper box body 1 and the lower box body 2 .

[0037] The above working principle: when it is necessary to dock and install the catheter 6 with the air inlet pipe 3 and the air outlet pipe 4 respectively, it is only necessary to first insert the catheter 6 into the inside of the air inlet pipe 3 and the air outlet pipe 4. At this time, the catheter 6 will drive the mounting ring 7 to move synchronously. When the mounting ring 7 is fully inserted into the inside of the positioning ring 9, the mounting ring 7 and the positioning ring 9 are fixed by the fixing component. At this time, the catheter 6 can be docked and installed with the air inlet pipe 3 and the air outlet pipe 4. At the same time, it can effectively improve the fixing effect between the catheter 6 and the air inlet pipe 3 and the air outlet pipe 4, and avoid the catheter 6 from falling off during use of the entire device. When the catheter 6 accidentally falls off, the alarm component will sound an alarm, thereby reminding medical staff, effectively improving the overall safety factor of the device. By setting the sterilizing filter 12, bacteria can be effectively killed, thereby reducing the spread of respiratory diseases. In addition, medical staff can also conveniently disassemble and replace the sterilizing filter 12, further improving the overall practicality of the device and saving time and effort.

[0038] In order to effectively carry out docking and installation between the conduit 6 and the air inlet pipe 3 and the air outlet pipe 4, the fixing assembly includes a plurality of fixing sleeves 11 fixedly connected to the outside of the positioning ring 9, and a fixing rod 14 is provided inside the fixing sleeve 11. One end of each two fixing rods 14 extends to the outside of the fixing sleeve 11 and is fixedly connected to a pull ring, and the outside of the fixing rod 14 is fixedly connected to a contact disk 15. The outside of the fixing rod 14 is provided with a return spring 16, which contacts between the return spring 16 and the contact disk 15 and the fixing sleeve 11. The contact surfaces of the fixing sleeve 11 and the positioning ring 9 are provided with guide grooves for the movement of the fixing rod 14, and the inside of the mounting ring 7 is provided with guide grooves for the movement of the fixing rod 14. When it is necessary to dock and install the conduit 6 with the air inlet pipe 3 and the air outlet pipe 4, you only need to pull the pull ring first, and the pull ring will drive The fixing rod 14 moves synchronously, and the fixing rod 14 drives the contact plate 15 to move synchronously. During the movement of the contact plate 15, the return spring 16 will be squeezed. At this time, the conduit 6 is inserted into the inside of the air inlet pipe 3 and the air outlet pipe 4, and the conduit 6 will drive the mounting ring 7 to move synchronously. When the mounting ring 7 is fully inserted into the inside of the positioning ring 9, the pull ring is released. At this time, the return spring 16 is reset, driving the contact plate 15 and the fixing rod 14 to move synchronously. When the fixing rod 14 is inserted into the guide groove inside the mounting ring 7, the mounting ring 7 and the positioning ring 9 can be fixed. At this time, the conduit 6 can be docked and installed with the air inlet pipe 3 and the air outlet pipe 4. At the same time, the fixing effect between the conduit 6 and the air inlet pipe 3 and the air outlet pipe 4 can be effectively improved, reducing the probability of the conduit 6 falling off.

[0039] Taking into account the need to remind medical staff when the catheter 6 falls off, the alarm component includes an alarm 10 respectively arranged on the outside of the air inlet pipe 3 and the air outlet pipe 4, and the two positioning rings 9 are each provided with a Hall sensor 17 inside, and the two mounting rings 7 are each provided with a magnetic block 13 that cooperates with the Hall sensor 17 on the outside. When the catheter 6 falls off, it will drive the mounting ring 7 to move synchronously, and the mounting ring 7 will drive the magnetic block 13 to move synchronously. When the magnetic block 13 is separated from the Hall sensor 17, the Hall sensor 17 will transmit a signal to the controller, and the controller will control the alarm 10 to sound. At this time, the medical staff can be reminded that the catheter 6 has fallen off, which effectively improves the overall practicality of the device (the Hall sensor 17 is an existing mature technology, so it will not be elaborated on here).

[0040] In order to facilitate medical staff to disassemble and replace the sterilizing filter 12, the sterilizing filter 12 is fixedly connected to the air inlet pipe 3 and the air outlet pipe 4 by threads. Since the sterilizing filter 12 is fixed to the air inlet pipe 3 and the air outlet pipe 4 by threads, and since the upper box body 1 and the lower box body 2 are also fixed by threads, it is convenient for medical staff to disassemble and replace the sterilizing filter 12.

[0041] In order to effectively improve the sealing between the mounting ring 7 and the positioning ring 9, rubber sealing rings 8 are bonded to the outside of the two mounting rings 7. Through the setting of the rubber sealing rings 8, the sealing between the mounting ring 7 and the positioning ring 9 can be effectively improved, thereby effectively improving the sealing between the conduit 6 and the air inlet pipe 3 and the air outlet pipe 4.

[0042] In addition, in order to effectively heat and humidify the gas, a heating humidifier 5 is fixedly connected to the outside of the upper box body 1. The output end of the heating humidifier 5 is connected to the inside of the air inlet pipe 3 through a pipe. Through the setting of the heating humidifier 5, the gas can be effectively heated and humidified, so that the air inhaled by the patient is closer to the heated and humidified gas in the human nasal cavity, reducing the irritation of the patient's airway and reducing the occurrence of airway allergic reactions.
