Problems solved by technology

Although it achieves the purpose of constant volume, the adjustment is more troublesome. For example, during the rescue process, it is found that the tidal volume needs to be adjusted, and the artificial ventilation has to be interrupted, and then the device is adjusted, which delays the rescue time
At the same time, it has a certain difference from the existing simple respirator in the operation mode, and it is difficult for medical staff to adapt quickly and affect the use effect

Embodiment Construction

[0017] See attached figure 1 , 2 As shown in , 3, the present invention discloses a simple respirator that can determine and control the tidal volume, which is composed of four parts: a working cylinder assembly, a balloon, a pipeline assembly and a mask.

[0018] Wherein, the working cylinder assembly is composed of a matched piston cylinder 7 and a piston 8. The front end of the piston cylinder 7 is provided with a neck tube connection seat 6, and the tail end is provided with a balloon connection seat 14. The piston cylinder 7 is made of a transparent material. The outer wall is provided with a scale, and the rear side of the piston 8 is connected with a tension spring 15 that provides a reset tension to make it move backward; through the movement of the piston 8 in the piston cylinder 7, the suction and exhaust actions are realized.

[0019] The balloon 10 is made of elastic rubber material, and can be designed in an ellipse for easy handling and extrusion. It is fixed by...

Abstract

The invention belongs to medical instruments and discloses a simple respirator capable of confirming and controlling the tidal volume. The simple respirator comprises a working barrel assembly, a balloon, a tube assembly and a mask. The working barrel assembly is composed of a piston barrel and a piston, wherein the piston barrel and the piston are matched; the piston barrel is made of transparent materials, the outer wall of the piston barrel is provided with scales, and the back side of the piston is connected with a tension spring. An inner cavity of the balloon is communicated with the piston barrel, and the balloon drives the piston to move through air pressure generated through compression or relaxation. The tube assembly comprises a neck tube, the back end of the neck tube is communicated with the piston barrel, a safety valve and an air inlet tube are arranged on the side wall of the neck tube, an exhaust one-way valve is arranged at the front end of the neck tube, and an air intake one-way valve is arranged on the air inlet tube. The mask is fixedly connected with the air outlet end of the exhaust one-way valve in the tube assembly through an exhalation valve. The simple respirator is compact in structure, small and flexible; the difference between the simple respirator and an existing simple respirator is small in operation method; the simple respirator is convenient to use, the tidal volume can be confirmed and controlled flexibly through the scale corresponding to the piston; the tidal volume can be adjusted at any time according to the needs in the process of salvage, and artificial respiration operation does not need to be stopped.

Description

technical field [0001] The invention relates to a medical device, in particular to a simple respirator commonly used in clinical rescue. Background technique [0002] The simple respirator in clinical use is also called a ball or a breathing bag, and it is the simplest artificial respiration device. In many situations such as no ventilator, power failure or ventilator failure, the simple respirator is the only means to artificially ventilate the patient. . Existing commonly used simple respirator is generally made of parts such as balloon, intake one-way valve, outlet one-way valve and mask, utilizes the compression and relaxation of balloon to realize artificial respiration purpose. The simple respirator with this structure cannot clearly determine the ventilation volume generated by each extrusion, that is, the tidal volume, and is usually operated by experience. In addition, different medical staff are affected by factors such as operating habits and hand size difference...
