An anesthesia reservoir for an anesthesia machine

Abstract

This utility model provides an anesthesia reservoir for an anesthesia machine, relating to the field of anesthesia machine technology. It includes a reservoir with a connecting tube at one end, a connecting ring in the middle, hinge shafts on both sides of the inner wall of the connecting ring, a limiting arc block in the middle of the hinge shafts, a rotating ring connected to the middle of the connecting ring, and a transmission component on the inner wall of the limiting arc block. The transmission component is driven by the rotating ring and connected to the limiting arc block. This invention solves the problem that the pressure applied to the reservoir in anesthesia machines cannot be precisely controlled, making it difficult to accurately control the amount of gas delivered according to the patient's needs. By deflecting the limiting arc block in this device, the degree of compression of the reservoir is limited, thereby controlling the amount of gas expelled by the compression and preventing excessive gas expulsion due to uncontrolled pressure, which would hinder the adjustment of the required respiratory rate.

Description

Technical Field

[0001] This utility model relates to the field of anesthesia machine technology, and more specifically, to an anesthesia reservoir bag for an anesthesia machine. Background Technology

[0002] Anesthesia machines anesthetize patients by delivering anesthetic gases to them for breathing. The amount of gas is controlled to match the patient's breathing volume. Excess gas is stored in a reservoir. When the gas output is insufficient for breathing needs, the reservoir is squeezed to expel and deliver gas, thus adjusting the gas delivery volume.

[0003] However, the discharge volume of existing gas reservoirs depends entirely on the squeezing force, and the squeezing force is entirely controlled by human intervention, making it difficult to accurately control the amount of gas delivered and thus difficult to adjust the amount of gas delivered by the gas reservoir. Utility Model Content

[0004] The purpose of this invention is to provide an anesthesia reservoir for an anesthesia machine, which solves the problem that the amount of gas delivered is difficult to precisely control according to the patient's needs because the force of the compression of the anesthesia machine reservoir cannot be precisely controlled.

[0005] The embodiments of this utility model are achieved through the following technical solutions:

[0006] This utility model provides an anesthesia reservoir for an anesthesia machine, including an airbag, a connecting tube at one end of the airbag, a connecting ring in the middle of the airbag, hinge shafts on both sides of the inner wall of the connecting ring, a limiting arc block in the middle of the hinge shaft, a rotating ring connected to the middle of the connecting ring, and a transmission component on the inner wall of the limiting arc block. The transmission component is driven by the rotating ring and is connected to the limiting arc block.

[0007] Preferably, the limiting arc block is an arc-shaped block connected inside the airbag via a hinge shaft, and the arc-shaped protrusion side of the limiting arc block is attached to the inner wall of the airbag.

[0008] Preferably, the two ends of the hinge shaft are connected to the inner wall of the connecting ring by torsion springs.

[0009] Preferably, the side wall of the connecting ring is provided with an annular groove that mates with the rotating ring, and the upper and lower sides of the rotating ring are provided with annular protrusions that mate with the upper and lower sides of the groove on the side wall of the connecting ring.

[0010] Preferably, the transmission assembly includes a connecting groove, a receiving rod, and a transmission gear. The connecting groove is disposed on both sides of the inner wall of the connecting ring, the receiving rod is connected in the connecting groove, and the transmission gear is disposed on the upper and lower end side walls of the receiving rod.

[0011] Preferably, the storage rod is equipped with a traction rope that connects to the opposite side of the limiting arc block.

[0012] Preferably, the transmission gear meshes and fits with the inner wall of the rotating ring.

[0013] Preferably, the connecting ring also includes a pin, which is a rod that passes through the connecting ring, and the top of the rotating ring is provided with several holes that cooperate with the pin.

[0014] The technical solution of this utility model embodiment has at least the following advantages and beneficial effects:

[0015] 1. By limiting the deflection of the arc block in the device, the degree of airbag compression is limited, thereby controlling the amount of gas expelled by the airbag under compression, so that it will not cause too much gas to be expelled at one time due to poor control of the compression force, making it difficult to adjust the amount of gas required for breathing.

[0021] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The following is combined with Figures 1 to 3 This utility model will be described in detail.

[0023] An anesthesia reservoir for an anesthesia machine includes an airbag 1. One end of the airbag 1 is provided with a connecting tube 101. A connecting ring 2 is provided in the middle of the airbag 1. Hinges 2011 are provided on both sides of the inner wall of the connecting ring 2. A limiting arc block 201 is provided in the middle of the hinge 2011. A rotating ring 202 is connected to the middle of the connecting ring 2. A transmission component is provided on the inner wall of the limiting arc block 201. The transmission component is driven by the rotating ring 202 and is connected to the limiting arc block 201.

[0024] First, the air bag 1 is connected to the anesthesia machine via the connecting tube 101. Then, the air bag 1 is used to provide auxiliary gas injection for the patient's respiratory support, or to store excess gas and release the gas to increase the respiratory requirement by controlling the squeezing of the air bag 1.

[0025] Furthermore, the limiting arc block 201 is an arc-shaped block connected inside the airbag 1 via a hinge shaft 2011. One side of the arc-shaped protrusion of the limiting arc block 201 is attached to the inner wall of the airbag 1. Both ends of the hinge shaft 2011 are connected to the inner wall of the connecting ring 2 via torsion springs. The side wall of the connecting ring 2 is provided with an annular groove that mates with the rotating ring 202. The upper and lower sides of the rotating ring 202 are provided with annular protrusions that mate with the upper and lower sides of the groove on the side wall of the connecting ring 2. The transmission assembly includes a connecting groove 203, a storage rod 2031, and a transmission gear 2032. The connecting groove 203 is provided on both sides of the inner wall of the connecting ring 2. The storage rod 2031 is connected in the connecting groove 203. The transmission gear 2032 is provided on the upper and lower side walls of the storage rod 2031. The storage rod 2031 is provided with a traction rope and is connected to the opposite side of the limiting arc block 201. The transmission gear 2032 meshes and fits with the inner wall of the rotating ring 202. The connecting ring 2 also includes a pin 204. The pin 204 is a rod body that passes through the connecting ring 2. The top of the rotating ring 202 is provided with several holes that cooperate with the pin 204.

[0026] Simultaneously, when it is necessary to compress the airbag 1 to expel gas, the rotating ring 202 can be rotated. When the rotating ring 202 rotates, its inner wall will mesh with the transmission gear 2032 in the connecting groove 203, thereby driving the transmission gear 2032 to rotate. When the transmission gear 2032 rotates, it will also drive the storage rod 2031 to rotate. When the storage rod 2031 rotates, it will wrap and store the traction rope connecting the limiting arc block 201. When the traction rope is stored, it will pull the limiting arc block 201. The fixed arc block 201 is deflected by the hinge shaft 2011, so that the two limiting arc blocks 201 will be deflected to a certain extent and then limited by the pin 204, so that the deflection angle of the limiting arc block 201 is stabilized. This ensures that when the airbag 1 is squeezed, the pressure will only reach the deflection point of the limiting arc block 201, thereby limiting the degree of compression of the airbag 1 and controlling the amount of gas discharged with each squeeze. This allows for better control and adjustment of the amount of gas discharged, making it easier to control breathing needs.

[0027] The following is a detailed implementation process of this utility model. First, the airbag 1 is connected to the anesthesia machine via the connecting pipe 101. Then, the airbag 1 provides auxiliary inflator for the patient's respiratory support, or stores excess gas. By controlling and squeezing the airbag 1, the gas is expelled to increase the respiratory demand. Simultaneously, when it is necessary to squeeze the airbag 1 to expel gas, the rotating ring 202 can be rotated. When the rotating ring 202 rotates, its inner wall engages with the transmission gear 2032 in the connecting groove 203, driving the transmission gear 2032 to rotate. When the transmission gear 2032 rotates, it also drives the storage rod 2031 to rotate. When 2031 rotates, it winds and stores the traction rope connecting the limiting arc block 201. When the traction rope is stored, it pulls the limiting arc block 201 to deflect through the hinge shaft 2011, causing the two limiting arc blocks 201 to deflect to a certain extent. Then, it is limited by the pin 204, so that the deflection angle of the limiting arc block 201 is stabilized. This ensures that when the airbag 1 is squeezed, it will only squeeze the deflection point of the limiting arc block 201, thereby limiting the degree of compression of the airbag 1 and controlling the amount of gas discharged with each squeeze. This allows for better control and adjustment of the amount of gas discharged, making it easier to control breathing needs.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
