Description

Respirator capable of simply adjusting tidal volume

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to respirator that can simply adjust tidal volume.

Background

Currently, the mainstream ventilatory assist devices in clinical practice are ventilators and simple ventilators. The breathing machine can well meet the requirement of auxiliary ventilation, but has the characteristics of high cost, inconvenient transportation and the like, and can be completely mastered only by long skill training. The simple respirator is relatively easy to operate, but the simple respirator is not easy to accurately control the gas output quantity given to a patient, particularly for infants, the pressing force is too large, so that the excessive pressing is easily caused, and the critical conditions of lung barotrauma, pneumothorax and the like are generated. Too low a pressure tends to cause insufficient ventilation. It is necessary to judge whether or not sufficient ventilation is given according to the feeling of manual pressure of the physician, and it is not suitable for beginners to grasp quickly and use flexibly.

Disclosure of Invention

The utility model discloses to the difficult drawback of controlling the air volume of respirator among the prior art, provide a respirator that can simply adjust tidal volume, the air volume is controlled to the quantity that this respirator accessible control gasbag was opened, and it is more simple and convenient to operate.

The invention aims to be realized by the following technical scheme: a respirator capable of simply adjusting tidal volume comprises two lane dividers, each lane divider comprises a transverse pipe, at least three connecting pipes are fixedly communicated with the transverse pipe, the connecting pipes on the two lane dividers correspond to each other one by one, air bags with strip structures are fixedly arranged between the mutually corresponding connecting pipes, one end of each air bag is provided with a switch for controlling the corresponding air bag to be opened and closed, a connecting air pipe is fixedly arranged on the transverse pipe on one lane divider, and an oxygen interface is fixedly arranged on the connecting air pipe; and a bent pipe is fixedly arranged on the transverse pipe on the other separator, and a breathing mask is connected on the bent pipe.

Preferably, the elbow is provided with a control valve for controlling the opening and closing of the elbow.

Preferably, the transverse pipes on the two lane dividers are parallel to each other, and all the air bags are arranged in parallel.

Preferably, the connecting pipe on the channel divider is perpendicular to the transverse pipe.

Preferably, the elbow is in threaded connection with the breathing mask.

Preferably, four connecting pipes are fixedly arranged on the pipeline, and the number of the air bags is four.

Preferably, the balloon is a soft balloon.

Compared with the prior art, the utility model discloses following beneficial effect has: a plurality of gasbags that set up in this application can all carry out independent switch and close through the switch that sets up, through opening the gasbag of different quantity, can make up out a gasbag that satisfies the required tidal volume of corresponding patient, no matter be under spontaneous respiration state or manual supplementary respiration state all can accomplish the supplementary oxygen supply and the ventilation to the patient. The operation is very convenient, and the operation requirement on a user is low.

Drawings

FIG. 1 is a perspective view of the present invention;

the labels in the figure are: 1. the device comprises a channel divider, a transverse pipe 2, a transverse pipe 3, a connecting pipe 4, an air bag 5, a switch 6, a connecting air pipe 7, an oxygen interface 8, a bent pipe 9, a breathing mask 10 and a control valve.

Detailed Description

The invention will be further described with reference to the embodiments shown in the drawings to which:

example 1

As shown in fig. 1, a respirator capable of simply adjusting tidal volume comprises two lane dividers 1, wherein each lane divider 1 comprises a transverse pipe 2, the transverse pipes 2 on the two lane dividers 1 are parallel to each other, the transverse pipes 2 are fixedly communicated with four connecting pipes 3, the connecting pipes 3 are perpendicular to the transverse pipes 2, the connecting pipes 3 on the two lane dividers 1 correspond to each other one by one, air bags 4 with strip structures are fixedly arranged between the mutually corresponding connecting pipes 3, the air bags 4 are flexible air bags 4, all the air bags 4 are arranged in parallel, one end of each air bag 4 is provided with a switch 5 for controlling the corresponding air bag 4 to be opened and closed, one of the transverse pipes 2 on one lane divider 1 is fixedly provided with a connecting air pipe 6, and the connecting air pipe 6 is fixedly provided with an oxygen connector 7; an elbow pipe 8 is fixedly arranged on the transverse pipe 2 on the other separator 1, and a breathing mask 9 is connected to the elbow pipe 8 through threads. And a control valve 10 for controlling the opening and closing of the elbow 8 is arranged on the elbow 8.

The opening and closing of each air bag 4 can be independently controlled through the switch 5 on each air bag 4, the ventilation volume of each air bag 4 is fixed, and the air bags 4 meeting the tidal volume required by the corresponding patient can be combined by calculating the air content of each air bag 4 and synchronously opening the number of the corresponding air bags 4. The auxiliary oxygen supply and ventilation of the patient can be completed in the spontaneous breathing state or the manual auxiliary breathing state. The operation is very convenient, and the operation requirement on a user is low.
