Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to an anesthesia respirator for thoracic surgery. Background Art

[0002] Thoracic surgery anesthesia respirators are medical devices used in thoracic surgery, especially in chest surgery, to provide anesthesia support, control ventilation, and maintain the patient's vital signs. However, existing thoracic surgery anesthesia respirators still have certain defects when used; During use, the anesthesia respirator is large in size and heavy in weight. During thoracic surgery, it will affect the operating space and flexibility of the anesthesiologist, and the overall operation requires the cooperation of multiple doctors, which makes the overall operation inconvenient and reduces the overall practical performance; In order to overcome the above-mentioned defects, the prior art 1 (Chinese patent with application number 201921117812.9 and application date 2019-07-10) is an anesthesia respirator for anesthesia department, comprising a main box and a base, wherein the main box is mounted on the upper outer wall of the base, and is improved on the basis of the existing anesthesia respirator for anesthesia department, and a tube collector, an elastic clamping disinfection box and other components are newly added to the existing anesthesia respirator for anesthesia department, wherein the tube collector is composed of a fixing block, a tube clamping seam, a fixing rod and a tube clamping ring, and the tube clamping seam between the tube clamping rings on the tube collector can be used to wrap the breathing tube into the tube clamping seam, so that the breathing tube can be easily and conveniently collected and sorted, and the newly added disinfection box and elastic clip can be used to sleeve the breathing tube that is not in use into the elastic clip, and the bottom end of the breathing tube is inserted into the interior of the disinfection box to prevent the inside of the breathing tube from being contaminated in the air, thereby greatly improving the practical performance and safety performance of the device; There is also prior art 2 (Chinese patent with application number 202322572896.8 and application date 2023-09-21) which discloses an anesthesia respirator, including a box, a pretreatment mechanism, a connecting mechanism, an inhalation mechanism, a fixing plate, a partition and a dosing barrel. A pretreatment mechanism for gas treatment is arranged in the middle of the inner cavity of the box, the connecting mechanism is arranged on one side of the box, the inhalation mechanism is arranged at one end of the box, the fixing plate is fixedly installed on the upper part of the inner cavity of the box, the partition is fixedly installed on the lower part of the back of the box, and the dosing barrel is arranged above the connecting mechanism. Through the arrangement of the pretreatment mechanism, the advantage of filtering and pre-treating the gas inhaled before atomization is achieved, thereby avoiding the presence of impurities inside and preventing damage to the human body. The first filter and the second filter are used to achieve the advantage of double-stage filtration, and the cooperation of the connecting plate, the limit frame, the spring, the top plate and the vertical rod can be used to limit and fix the first filter and the second filter, and at the same time facilitate the subsequent assembly, disassembly and replacement operations; And prior art three (Chinese patent with application number 202210650185.5 and application date 2022-06-09) is an anesthesia respirator, control method, terminal and storage medium for the anesthesia department. The anesthesia respirator for the anesthesia department includes: a casing, a breathing mask, a trachea, a switch, a gas tank, a main controller, an anesthesia depth detection module, an anesthesia quality evaluation module, a gas supply volume calculation module, and a memory. The anesthesia depth detection module can comprehensively reflect the state of the anesthetized patient based on the fusion analysis of multiple physiological parameters; the signal can be directly obtained from the existing necessary anesthesia monitoring equipment for analysis to achieve anesthesia depth detection; at the same time, the data of vital signs collected by the monitoring equipment is analyzed and processed through the anesthesia quality evaluation module to obtain a surgical quality control index. The higher the surgical quality control index, the better the quality of surgical anesthesia; the surgical anesthesia quality of a department or a medical staff can be measured more objectively.

[0003] Although the existing technology can improve the overall practical performance, during the operation, the breathing mask is fixed on the user's face to perform anesthesia operations.
