Description

Technical Field

[0001] This utility model relates to the field of medical product testing technology, specifically a quality testing device for a medical anesthesia reservoir. Background Technology

[0002] The main function of an anesthesia reservoir is to store fresh gas from the anesthesia machine and regulate the gas supply. The working principle of the anesthesia reservoir is that when the gas supply is more than the system needs, the excess gas can be expelled. When the gas supply is insufficient, the reservoir can be manually inflated by pressing to supplement the gas supply. In the production and testing process of medical anesthesia reservoirs, it is necessary to monitor the product pressure and conduct quality inspection. The traditional testing method is to test the pressure required for the reservoir to expand by taking samples. The testing process requires corresponding quality inspection equipment.

[0003] The existing technology has the following shortcomings: Application number 202110851015.9 proposes a reciprocating medical anesthesia gas reservoir quality testing device, including a support base, a circular support frame, a ventilation tube, and a push-switching component. The circular support frame is fixedly installed on the support base, the ventilation tube is installed on the circular support frame, and the push-switching component is also installed on the circular support frame. Through the action of the first slotted plate, a sliding push plate reciprocates up and down. The sliding push plate, through a fourth spring, pushes a disc frame to reciprocate up and down. The reciprocating motion of the disc frame compresses the gas inside the circular support frame, and the gas enters the gas reservoir through the ventilation tube to test the quality of the gas reservoir.

[0004] The aforementioned equipment has a complex overall structure and uses a large number of springs to achieve its purpose. The springs have frequent working cycles, and since springs are generally made of metal, they are prone to fatigue loads as the equipment is used for a long time, leading to gradual fatigue failure and affecting normal use. In subsequent maintenance, the complex structure will also increase the cost and time of equipment maintenance. In addition, the equipment can only test a single air bladder at a time, and the testing efficiency can be further improved. Utility Model Content

[0010] As a preferred technical solution of this utility model: there are four sets of insertion rods, which are fixedly installed at the bottom of the protective cover. The placement platform has insertion holes that are adapted to the insertion rods and correspond to the positions of the insertion rods. The opening corresponds to the connecting pipe, and the width of the opening is greater than the diameter of the connecting pipe.

This medical anesthesia gas reservoir quality testing device comprises a gas storage device, a connecting pipe, a storage box, a placement platform, a gas storage chamber, a piston, and an electric telescopic rod. The anesthesia gas reservoir to be tested is placed in the placement slot and connected to the connecting pipe. The output end of the electric telescopic rod is extended to push the piston into the corresponding gas storage chamber, compressing the gas in the gas storage chamber. The gas is then discharged from the connecting pipe into the connected anesthesia gas reservoir, causing it to expand. After a preset amount of gas is injected into the anesthesia gas reservoir, if the anesthesia gas reservoir ruptures, it is recycled to the waste storage chamber. If it does not rupture, it is a qualified product and can be collected in the qualified product storage chamber. The overall equipment is simpler in structure while ensuring functionality, reducing the failure rate, facilitating maintenance, and reducing maintenance costs and time.

[0014] 2. This medical anesthesia gas reservoir quality testing device comprises a gas storage device, a gas storage chamber, a placement platform, a placement slot, and an electric telescopic rod. The anesthesia gas reservoir to be tested is placed in the placement slot and connected to a connecting pipe. Gas from the gas storage chamber enters the connected anesthesia gas reservoir through the connecting pipe, causing the anesthesia gas reservoir to inflate. The device then observes whether the gas reservoir ruptures, thus achieving the testing effect. Furthermore, there are four sets of placement slots and gas storage chambers, allowing for the simultaneous testing of multiple anesthesia gas reservoirs, thereby improving testing efficiency.
