Description

Technical Field

[0001] This utility model relates to the field of respirator technology, specifically a respirator that facilitates flow monitoring. Background Technology

[0002] A respirator (also often called an emergency respirator or portable ventilator) is a device used to provide artificial ventilation in emergency situations, typically for patients who are unable to breathe independently or have difficulty breathing, to help maintain or restore their normal oxygen supply. These devices are designed to be lightweight and easy to operate, suitable for emergency rescue and mobile use, and are usually used at the scene of an emergency, in a hospital emergency room, or during transport.

[0003] The shortcomings of existing technology:

[0004] Most ventilators currently lack flow monitoring capabilities. Excessive ventilation can lead to excessive air pressure, which can damage the patient's lungs and prevent healthcare workers from ensuring that the ventilation provided by the ventilator meets the patient's needs. Utility Model Content

[0005] The purpose of this invention is to provide a respirator that facilitates flow monitoring, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a respirator for easy flow monitoring, comprising an airbag body, a flow monitoring mechanism at one end of the airbag body, a one-way valve fixedly connected to the top of the airbag body, a fixing mechanism at one end of the one-way valve, and the flow monitoring mechanism comprising:

[0007] A flow sensor is disposed at one end of the airbag body;

[0008] A U-shaped tube is connected to the surface of the airbag body;

[0009] An air spring, which is fixedly connected inside the U-shaped tube.

[0010] Preferably, the fixing mechanism includes:

[0011] A face mask, wherein the face mask is disposed at one end of a one-way valve;

[0012] A silicone pad, which is adhered to the outer surface of the face mask;

[0013] An airbag tube is fixedly connected to one end of the mask;

[0014] The velvet cloth is fixedly attached to the outer surface of the airbag tube.

[0015] Preferably, the surface of the one-way valve is connected to a pressure safety valve to protect the patient and the device from damage caused by excessive air pressure.

[0016] Preferably, an air intake valve is fixedly connected to the bottom of the airbag body, and an air storage valve is threadedly connected to the bottom of the air intake valve.

[0017] Preferably, an oxygen connection pipe is fixedly connected to the bottom of the gas storage valve for connecting to an oxygen supply device to provide oxygen to the patient for emergency treatment.

[0018] Preferably, the flow sensor is a CAFS3000.

[0019] Preferably, a protective shell is fixedly connected to the outer surface of the flow sensor, and one side of the protective shell is fixedly connected to the top of one end of the airbag body.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This is a respirator that facilitates flow monitoring. The flow monitoring mechanism includes a flow sensor, a U-tube, and an air spring. When gas flows through a thermal flow sensing chip inside the flow sensor, the gas flow carries away a certain amount of heat. The change in heat detected by the flow sensor can be used to calculate the flow rate. The greater the flow rate, the more heat is carried away. The flow sensor will output a corresponding signal based on this change. The U-tube is connected to one end of the airbag body to help disperse the pressure inside the airbag body. Together with the air spring as a buffer device, it can provide a certain amount of elastic support during the airflow process inside the airbag body, reduce the rapid change in pressure, and avoid excessive air pressure, which could damage the patient's lungs. This helps medical personnel ensure that the ventilation provided by the device meets the patient's needs.

[0022] 2. This ventilator, which facilitates flow monitoring, has a fixing mechanism including a mask, a silicone pad, an air bag tube, and a cloth. The air bag tube is placed around the patient's head, and then one side of the air bag tube is squeezed to inflate the air bag tube, causing it to expand and allowing the mask and silicone pad to fit tightly against the patient's face. This effectively prevents airborne bacteria and viruses from entering the patient's airway, reducing the risk of infection. It also makes it easy for patients with different head circumferences to use the mask, avoiding the problem of the mask being too tight and constricting patients with larger head circumferences.

[0032] Example 1

[0033] Please see Figure 1-4As shown, this utility model provides a respirator technical solution for easy flow monitoring: it includes an airbag body 1, a flow monitoring mechanism 2 at one end of the airbag body 1, a one-way valve 3 fixedly connected to the top of the airbag body 1, and a fixing mechanism 4 at one end of the one-way valve 3. The flow monitoring mechanism 2 includes a flow sensor 201, which is located at one end of the airbag body 1; a U-shaped tube 202, which is connected to the surface of the airbag body 1; and an air spring 203, which is fixedly connected inside the U-shaped tube 202. The flow sensor 201 is composed of a MEMS thermal flow sensor chip, an operational amplifier, a microcontroller MCU, etc., through which gas flows... When a thermal flow sensor chip is installed inside the flow sensor 201, the flow of gas will carry away a certain amount of heat. The change in heat detected by the flow sensor 201 can be used to calculate the flow rate. The greater the flow rate, the more heat is carried away. The flow sensor 201 will output a corresponding signal based on this change. Then, the U-shaped tube 202 is connected to one end of the airbag body 1 to help disperse the pressure inside the airbag body 1. Together with the air spring 203, which acts as a buffer device, it can provide a certain amount of elastic support during the airflow process inside the airbag body 1, reduce the rapid change in pressure, and avoid excessive air pressure, which could damage the patient's lungs. This helps medical personnel ensure that the ventilation provided by the device meets the patient's needs.

[0034] The fixing mechanism 4 includes a face mask 401, which is disposed at one end of the one-way valve 3; a silicone pad 402, which is adhered to the outer surface of the face mask 401; an airbag tube 403, which is fixedly connected to one end of the face mask 401; and a velvet cloth 404, which is fixedly connected to the outer surface of the airbag tube 403. When using the device, the airbag tube 403 is placed around the patient's head, and then one side of the airbag tube 403 is squeezed to inflate the airbag tube 403, causing the airbag tube 403 to expand and make the face mask 401 and the silicone pad 402 fit tightly against the patient's face. This can effectively prevent bacteria and viruses in the air from entering the patient's airway, reduce the risk of infection, and also make it easier for patients with different head circumferences to adapt to the use of the face mask 401, avoiding excessive tightness that may constrict patients with larger head circumferences.

[0035] The surface of the one-way valve 3 is connected to a pressure safety valve 5 to protect the patient and the device from damage caused by excessive air pressure.

[0036] An air inlet valve 6 is fixedly connected to the bottom of the airbag body 1. An air storage valve 7 is threadedly connected to the bottom of the air inlet valve 6 to control the inflow and outflow of gas in the airbag body 1, ensuring that the patient inhales oxygen while expelling unnecessary gas in a timely manner.

[0037] An oxygen connection pipe 8 is fixedly connected to the bottom of the gas storage valve 7, which is used to connect to an oxygen supply device to provide oxygen to the patient for emergency treatment.

[0038] The flow sensor model 201 is CAFS3000.

[0039] A protective shell is fixedly connected to the outer surface of the flow sensor 201, and one side of the protective shell is fixedly connected to the top of one end of the airbag body 1.

[0040] In this device, the airbag tube 403 is placed around the patient's head, and then one side of the airbag tube 403 is squeezed to inflate the airbag tube 403, causing it to expand and allowing the mask 401 and silicone pad 402 to fit snugly against the patient's face. This effectively prevents airborne bacteria and viruses from entering the patient's airway, reducing the risk of infection. It also allows for easy fitting of the mask 401 to patients with different head circumferences, avoiding excessive tightness for patients with larger head circumferences. Subsequently, the flow sensor 201, composed of a MEMS thermal flow sensor chip, operational amplifier, and microcontroller MCU, is used. Gas flows through a thermal flow sensor within the flow sensor 201. When the gas flows, it carries away a certain amount of heat. The heat change detected by the flow sensor 201 can be used to calculate the flow rate. The greater the flow rate, the more heat is carried away. The flow sensor 201 will output a corresponding signal based on this change. Then, the U-shaped tube 202 is connected to one end of the airbag body 1 to help disperse the pressure inside the airbag body 1. Together with the air spring 203, which acts as a buffer device, it can provide a certain amount of elastic support during the airflow process inside the airbag body 1, reduce the rapid change in pressure, and avoid excessive air pressure, which could damage the patient's lungs. This helps medical staff ensure that the ventilation provided by the device meets the patient's needs.
