Description

Technical Field

[0001] The invention belongs to the technical field of breathing bags for anesthesia machines, and in particular relates to a self-deflation type breathing bag for anesthesia machines. Background Art

[0002] The anesthesia reservoir bag, also known as the anesthesia breathing bag or anesthesia machine breathing bag, is an important part of the anesthesia machine. It is connected to the anesthesia ventilator to provide stable breathing support for the patient and plays the role of storing gas, ensuring that the patient's oxygen supply and the delivery of anesthetic gas during surgery are safe and effective. In clinical applications, the anesthesia machine breathing bag provides stable ventilation support for patients before anesthesia and during anesthesia recovery. By squeezing the breathing bag, a regular oxygen supply can be provided to the patient, thereby maintaining and increasing the body's ventilation volume, which helps to improve the patient's breathing condition; in emergency situations such as hypoxemia, the breathing bag can provide the patient with a high concentration of oxygen, which helps to correct the hypoxic state and protect the patient's life safety.

[0003] At present, the breathing bag of anesthesia machine is crucial in medical treatment. However, its design has obvious defects: there is a lack of protective deflation device, which may lead to serious medical risks. In the machine-controlled state, the Bypass function of the APL valve effectively prevents barotrauma and ensures the safety of patients. However, problems are prominent during manual ventilation. Especially during the anesthesia recovery period, patients are usually equipped with artificial airways, and manual ventilation becomes the norm at this time. Unfortunately, many medical staff do not adjust the APL valve to the "0" position at the end of manual ventilation, resulting in a large amount of anesthetic gas and oxygen accumulating inside the breathing bag, and these gases cannot be discharged normally. As the pressure continues to accumulate, the breathing bag faces the risk of bursting, which will directly cause barotrauma to the patient, and may further cause a series of serious complications such as emphysema, pulmonary hemorrhage, circulatory dysfunction, and acute respiratory distress. These complications not only greatly increase the patient's pain and difficulty of recovery, but in severe cases can lead to respiratory failure, directly threatening the patient's life safety and causing a high mortality rate. In view of the urgency and severity of the above problems, we propose an anesthesia machine breathing bag with self-deflation. Summary of the invention

[0004] The purpose of the present invention is to provide a self-deflation anesthesia machine breathing bag, so as to solve the problem proposed in the above background technology that the medical staff does not adjust the APL valve to the "0" position at the end of manual ventilation, resulting in a large amount of anesthetic gas and oxygen accumulated inside the breathing bag, and these gases cannot be discharged normally. As the pressure continues to accumulate, the breathing bag faces the risk of bursting, which will directly cause barotrauma to the patient, and may further cause a series of serious complications such as emphysema, pulmonary hemorrhage, circulatory dysfunction, acute respiratory distress, etc. These complications not only greatly increase the patient's pain and difficulty of recovery, but in severe cases can lead to respiratory failure, directly threatening the patient's life safety and causing a high mortality rate.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a self-deflation type anesthesia machine breathing bag, comprising a breathing bag body and an air inlet, the top of the breathing bag body is provided with an air inlet, the bottom of the breathing bag body is provided with an air outlet, the air inlet and the air outlet both extend into the interior of the breathing bag body, a plastic film is provided at the bottom of the air outlet, an upper fixing ring is provided at the top of the plastic film, a lower fixing ring is provided at the bottom of the plastic film, the plastic film is clamped between the upper fixing ring and the lower fixing ring, and the plastic film is clamped at the bottom of the air outlet through the upper fixing ring and the lower fixing ring.

[0006] Preferably, the upper fixing ring, the plastic film and the top corners of the lower fixing ring are all provided with limiting holes, the limiting holes run through the top and bottom, there are four limiting holes, and limiting rods are clamped inside the limiting holes.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. By clamping the plastic film inside the upper fixing ring and the lower fixing ring, and then installing it inside the air outlet, when the anesthesia machine is in use, when a large amount of anesthetic gas and oxygen accumulates inside the breathing bag, the plastic film will burst, thereby discharging the anesthetic gas and oxygen. A deflation device is provided to avoid the risk of bursting and improve safety during use.

[0013] 2. Place the plastic film between the upper fixing ring and the lower fixing ring, insert the limiting rod into the corresponding limiting hole, clamp the plastic film, and install it inside the air outlet. When the plastic film bursts, press the clamping block, the spring expands and contracts, the clamping block enters the groove, separates the clamping block from the clamping slot, and then take out the upper fixing ring, the plastic film and the lower fixing ring from the air outlet, so as to facilitate the replacement of the plastic film. By opening the cover, a small amount of anesthetic gas and oxygen can be discharged from the air outlet pipe and the whistle, and the whistle can be blown to serve as a reminder. The plastic film will burst only when a large amount of anesthetic gas and oxygen are produced. BRIEF DESCRIPTION OF THE DRAWINGS
