Description

Technical Field

[0001] The invention relates to the technical field of artificial respirators, in particular to a simple artificial respirator with intelligent operation. Background Art

[0002] Artificial respirators are used to perform cardiopulmonary resuscitation or to provide artificial respiration to patients who are unable to breathe on their own or to provide oxygen to patients who are hypoxic. When the artificial respirator is connected to an oxygen supply device, oxygen is provided to the patient through the air storage bag to the breathing bag. The oxygen concentration varies depending on the oxygen flow rate, tidal volume, respiratory rate and operator skills.

[0003] However, operators have different hands and different squeezing strengths, and it is impossible to judge whether the air delivery volume meets the minimum tidal volume for rescuing patients. If the mask leak cannot be found in time during the operation, it will waste oxygen and affect the timeliness of rescue. In view of this, we propose a simple artificial respirator with intelligent operation. Summary of the invention

[0004] The purpose of the present invention is to provide a simple artificial respirator with intelligent operation to solve the problem proposed in the above background technology that the different squeezing methods of the operator affect the air supply volume and the problem that the mask leakage cannot be discovered in time.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0026] The simple artificial respirator with intelligent operation, in order to facilitate the operator to use the breathing bag, the present invention improves the breathing bag 1, as a preferred embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, it includes a breathing bag 1, one end of the breathing bag 1 is connected to a connecting column 2, one side of the connecting column 2 is connected to a mask 3, one side of the top of the breathing bag 1 is connected to an air pressure alarm device 4, the bottom end of the breathing bag 1 is provided with a bottom port 10, the top of the breathing bag 1 is provided with a top port 11, one side of the top port 11 is provided with an air column 12, one side of the breathing bag 1 is provided with a plurality of thumb positions 13, and the other side of the breathing bag 1 is provided with four finger positions 14.

[0027] In this embodiment, the breathing bag 1 is made of silica gel, which has good flexibility, is comfortable to squeeze, and does not hurt the hands. The air pressure alarm device 4 is made of PP material in one piece, which is light in weight, strong in strength, and durable.

[0028] Specifically, the breathing bag 1 is elliptical and has a hollow structure inside. The bottom port 10 and the top port 11 are circular structures and the insides are connected with the inside of the breathing bag 1 to facilitate the circulation of oxygen.

[0029] Furthermore, the air column 12 is located on the top of the breathing bag 1 , and an air channel 120 is opened on the top surface of the air column 12 . The air channel 120 is connected to the interior of the breathing bag 1 , so that the internal pressure of the breathing bag 1 can be transmitted to the air pressure alarm device 4 through the air channel 120 .

[0030] In addition, there are three thumb positions 13 and the normal angle between every two of them is 15°. The four-finger positions 14 and the thumb positions 13 are relatively distributed. Different thumb positions 13 correspond to different exhaust volumes, so that the operator has a measure in mind for easy operation.

[0031] It is worth noting that a base 20 is provided at one end of the connecting column 2, and a top platform 21 is vertically provided at the other end of the connecting column 2. A connecting platform 30 is provided on the top surface of the mask 3. The base 20 is plugged into and matched with the top port 11, and the top platform 21 is plugged into and matched with the connecting platform 30, so that oxygen can flow to the patient's mouth and nose.

[0032] Example 2
