Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a ventilator. Background Technology

[0002] A manual ventilator is a medical device that allows manual control of the respiratory rate and inspiratory time.

[0003] Currently, manually operated ventilators mainly consist of an air bag, a pressure relief valve, and a mask. Medical staff press the air bag to depressurize the gas in the air bag and then transfer it to the mask, thereby providing assisted breathing for the patient.

[0004] However, manual ventilators require professional medical personnel to control the frequency of bag compressions. In actual operation, ordinary personnel without medical training often find it difficult to control the compression frequency, which can lead to situations in special circumstances, such as in the field, where the compression frequency may be too fast or too slow, making it impossible to help the patient breathe effectively. On the other hand, the pressure range of the pressure safety valve also needs to be adjusted before using a manual ventilator, and there is a certain degree of unreliability in the operation of ordinary personnel. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a ventilator to solve the technical problems in the background art where ordinary people cannot control the pressing frequency when using a manual ventilator, which makes it impossible to help patients breathe effectively. On the other hand, ordinary people cannot effectively adjust the pressure range of the pressure safety valve, which also leads to unreliability.

[0006] The present invention provides a ventilator, comprising a ventilator mask, a pneumatic module and a reciprocating drive module connected in sequence to the mask;

[0007] The pneumatic module includes a main cavity with a piston and two sub-cavities, two one-way valves disposed in the sub-cavities, and a connecting rod that connects each of the pistons to each other.

[0008] The main cavity is connected to the reciprocating drive module. The reciprocating drive module is used to cyclically input the drive medium into the main cavity and, through the corresponding piston and the connecting rod, cause the piston in the sub-cavity to perform reciprocating motion.

[0009] Both sub-cavities are connected to the face mask, and the input and output ends of each one-way valve in the two sub-cavities are arranged oppositely, so that one sub-cavity introduces gas from the atmosphere through the corresponding two one-way valves and directs it toward the face mask, while the other sub-cavity introduces gas output from the face mask through the corresponding one-way valve and directs it toward the atmosphere.

[0010] Furthermore, the reciprocating drive module includes an automatic reciprocating valve and a cylinder connected to the automatic reciprocating valve.

[0011] Furthermore, the automatic reciprocating valve is connected to the main cavity.

[0012] Furthermore, the pneumatic module includes an inhalation sub-cavity and an exhalation sub-cavity, and an inhalation piston and an exhalation piston are respectively provided in the inhalation sub-cavity and the exhalation sub-cavity.

[0013] Furthermore, a main piston is provided in the main cavity, wherein one end of the connecting rod is connected to the main piston, and the other end is connected to the inhalation piston and the exhalation piston respectively.

[0014] Furthermore, the connecting rod includes a main rod body and two sub-rod bodies connected to the main rod body. The main rod body is connected to the main piston, and the two sub-rod bodies are respectively connected to the inhalation piston and the exhalation piston.

[0015] Furthermore, the intake sub-cavity is provided with a first one-way valve and a second one-way valve, and the input ends and output ends of the first one-way valve and the second one-way valve are arranged oppositely.

[0016] Furthermore, the exhalation sub-cavity is provided with a third one-way valve and a fourth one-way valve, with the input ends and output ends of the third one-way valve and the fourth one-way valve being arranged oppositely.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In the ventilator provided by this utility model, the pneumatic module and reciprocating drive module enable operators to help patients breathe effectively without professional training, while ensuring the reliability of air pressure. The pneumatic module includes a main chamber with a piston, two sub-chambers, two one-way valves located in the sub-chambers, and connecting rods that connect each piston to the others. The reciprocating drive module cyclically inputs the driving medium into the main chamber, enabling the corresponding piston in the main chamber to reciprocate. The connecting rods then synchronize the reciprocating motion of the corresponding pistons in the sub-chambers. Since the input and output ends of each one-way valve in the two sub-chambers are opposite, when the pistons in the two sub-chambers reciprocate... During forward operation, one sub-chamber introduces atmospheric gas, while the other sub-chamber introduces the patient's exhaled air. Subsequently, when the pistons in the two sub-chambers move in reverse, the one-way valve's unidirectional output characteristic allows atmospheric gas to enter the mask, while the patient's exhaled air is expelled back into the atmosphere. This utilizes atmospheric gas to assist the patient's breathing, eliminating the need for depressurization. This addresses the technical problem in existing technologies where ordinary personnel cannot effectively adjust the pressure range of the pressure safety valve, leading to unreliability. Simultaneously, the reciprocating drive module cyclically inputs the driving medium into the main chamber, eliminating the need for manual control of the breathing rate and avoiding the drawbacks of excessively fast or slow breathing rates, thus achieving the goal of assisting the patient's breathing effectively.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] Please see Figures 1 to 4 The image shows a ventilator in one embodiment of the present invention, comprising a ventilator mask 100, a pneumatic module 200 and a reciprocating drive module 300 connected in sequence to the mask 100.

[0028] Specifically, in order to enable ordinary people to use the ventilator of this embodiment to help patients breathe effectively and ensure reliability, in this embodiment, the pneumatic module 200 includes a main cavity 210 with a piston and two sub-cavities, two one-way valves disposed in the sub-cavities, and a connecting rod 240 that connects each piston to the others.

[0029] The main cavity 210 is connected to the reciprocating drive module 300. The reciprocating drive module 300 is used to cyclically input the drive medium into the main cavity 210 and, through the corresponding piston and connecting rod 240, make the piston in the sub-cavity perform reciprocating motion.

[0030] Both sub-cavities are connected to the mask 100, and the input and output ends of each one-way valve in the two sub-cavities are arranged in opposite directions, so that one sub-cavity introduces gas from the atmosphere through the corresponding two one-way valves and inputs it toward the mask 100, while the other sub-cavity introduces gas output from the mask 100 through the corresponding one-way valve and outputs it toward the atmosphere.

[0031] In other words, when using a ventilator, the mask 100 is first put on the patient's mouth and nose. The reciprocating drive module 300 cyclically inputs the driving medium into the main chamber 210, causing the corresponding piston within the main chamber 210 to reciprocate. Utilizing the linkage of the connecting rod 240, the corresponding pistons in the sub-chambers reciprocate synchronously. Since the input and output ends of each one-way valve in the two sub-chambers are set oppositely, when the pistons in the two sub-chambers move in the forward direction, one sub-chamber can introduce atmospheric gas, and the other sub-chamber can introduce the patient's exhaled air. Subsequently, when the two sub-chambers... When the piston inside the body moves in reverse, the one-way valve has a one-way output characteristic, allowing atmospheric gas to enter the mask 100 and the patient's exhaled gas to exit into the atmosphere. This utilizes atmospheric gas to help the patient breathe, eliminating the need to depressurize the gas. This solves the technical problem in existing technologies where ordinary personnel cannot effectively adjust the pressure range of the pressure safety valve, leading to unreliability. At the same time, the reciprocating drive module 300 cyclically inputs the drive medium into the main cavity 210, eliminating the need for manual control of the breathing rate and avoiding the drawbacks of excessively fast or slow breathing rates, thus effectively assisting the patient's breathing.

[0032] Specifically, to further understand this case, in this embodiment, the pneumatic module 200 includes an inhalation sub-cavity 220 and an exhalation sub-cavity 230. An inhalation piston 221 and an exhalation piston 231 are respectively provided in the inhalation sub-cavity 220 and the exhalation sub-cavity 230. A main piston 211 is provided in the main cavity 210. One end of the connecting rod 240 is connected to the main piston 211, and the other end is connected to the inhalation piston 221 and the exhalation piston 231 respectively.

[0033] In some preferred embodiments, the connecting rod 240 has three connecting ends, namely, the connecting rod 240 includes a main rod body 241 and two sub-rod bodies 242 connected to the main rod body 241. The main rod body 241 is connected to the main piston 211, and the two sub-rod bodies 242 are respectively connected to the inhalation piston 221 and the exhalation piston 231.

[0034] Furthermore, to facilitate the introduction of atmospheric gas and the patient's exhalation output, in this embodiment, the inhalation sub-cavity 220 is provided with a first one-way valve 222 and a second one-way valve 223, with the input and output ends of the first one-way valve 222 and the second one-way valve 223 being arranged in opposite directions. The exhalation sub-cavity 230 is provided with a third one-way valve 232 and a fourth one-way valve 233, with the input and output ends of the third one-way valve 232 and the fourth one-way valve 233 being arranged in opposite directions.

[0035] Please see Figure 3As shown, when the inhalation piston 221 and the expiration piston 231 move in the forward direction, the first one-way valve 222 introduces atmospheric gas into the inhalation sub-chamber 220, and the second one-way valve 223 is in a closed state. The third one-way valve 232 introduces the patient's exhaled gas into the expiration sub-chamber 230, and the fourth one-way valve 233 is in a closed state. Please refer to [link / reference needed]. Figure 4 As shown, when the inhalation piston 221 and the exhalation piston 231 move in opposite directions, the first one-way valve 222 is in a closed state, the second one-way valve 223 introduces gas into the mask 100 for the patient to breathe, the third one-way valve 232 is in a closed state, and the fourth one-way valve 233 outputs the gas exhaled by the patient to the atmosphere.

[0036] In addition, in this embodiment, the reciprocating drive module 300 includes an automatic reciprocating valve 310 and a cylinder 320 connected to the automatic reciprocating valve 310. The automatic reciprocating valve 310 is connected to the main chamber 210. In some practical cases, the automatic reciprocating valve 310 can be a ZDV-08 series automatic reciprocating valve 310, and the cylinder 320 can be a MDBB32-25Z cylinder 320. It should be noted that the automatic reciprocating valve 310 is a commonly used control valve with an automatic switching function. It can work cyclically within a certain working pressure range. The automatic reciprocating valve 310 is used to cyclically input gas into the main chamber 210 for the main piston 211 to reciprocate.

[0037] In summary, the ventilator according to one embodiment of the present invention has at least the following beneficial effects compared with ventilators in the prior art:

[0038] In the ventilator provided by this utility model, the pneumatic module 200 and the reciprocating drive module 300 enable operators to help patients breathe effectively without professional training, and ensure the reliability of air pressure. The pneumatic module 200 includes a main chamber 210 with a piston, two sub-chambers, two one-way valves located in the sub-chambers, and a connecting rod 240 connecting each piston to the others. The reciprocating drive module 300 cyclically inputs the driving medium into the main chamber 210, enabling the corresponding piston in the main chamber 210 to reciprocate. The connecting rod 240's linkage allows the corresponding pistons in the sub-chambers to reciprocate synchronously. Since the input and output ends of each one-way valve in the two sub-chambers are oppositely arranged, when the two... When the pistons in the sub-cavities move in the forward direction, one sub-cavity can introduce air from the atmosphere, and the other sub-cavity can introduce the patient's exhaled air. Subsequently, when the pistons in the two sub-cavities move in the reverse direction, the one-way valve has a one-way output characteristic, allowing air from the atmosphere to enter the mask 100 and the patient's exhaled air to exit into the atmosphere. This utilizes atmospheric air to help the patient breathe, eliminating the need to depressurize the air. This solves the technical problem in existing technologies where ordinary personnel cannot effectively adjust the pressure range of the pressure safety valve, resulting in unreliability. At the same time, the reciprocating drive module 300 cyclically inputs the driving medium into the main cavity 210, eliminating the need for manual control of the breathing rate and avoiding the drawbacks of excessively fast or slow breathing rates, thus achieving the goal of helping the patient breathe effectively.
