Abstract

The utility model discloses a portable respirator, which is composed of a casing, an air pocket communicate with air inlet and outlet tubes and a compressing mechanism; wherein, the compressing mechanism is composed of a cam, which is driven by a motor, and a clamping plate, which is contacted with the cam; the clamping plate is positioned at the bottom of the air pocket, and a inner chamber of the air pocket is provided with a reset spring. The utility model can be used instead of a large respirator device in many undeveloped areas, due to the simple structure, small volume, convenient carrying, low manufacturing cost and convenient use, and has high value of use and popularization.

Description

A kind of portable respirator

Technical field

This utility model relates to a kind of armarium, specifically, relates to a kind of portable respirator.

Background technology

Respirator is the armarium of a kind of hospital indispensability, particularly often uses in critical patient's daily nursing or some operation processs, and at present, the most because complex structure of domestic employed respirator, volume is big, equipment quality is big, is not easy to move.In many cases, as 120 emergency tenders, often need carry out field first aid to some critical patients, guarantee patient in being sent to the way of hospital, keep necessary human physiological activity, the medical aid of products for further, wherein, the eupnea of keeping patient is important one.Under a lot of situations, patient has lost the ability of autonomous respiration, need implement controlled breathing to patient.And existing respirator carries because of inconvenience, is difficult in emergency circumstances use above-mentioned.

Summary of the invention

The purpose of this utility model is to provide a kind of simple in structure, easy to use, light weight, volume little, cheap, portable portable respirator.

For achieving the above object, the technical scheme that this utility model adopted is: a kind of portable respirator, comprise housing, the air bag and the compressing mechanism thereof that are communicated with air inlet pipe, exhaustor, described compressing mechanism comprises motor-driven cam, the pressing plate that contacts with cam, described pressing plate is positioned at the bottom of air bag, and the inner chamber of described air bag is provided with back-moving spring.

Below be the improvement of technical solutions of the utility model:

The inner chamber of described air bag is provided with the first helical pitch bar and the second helical pitch bar, and an end of the described first helical pitch bar and the second helical pitch bar stretches out from the hole on the pressing plate.

The described first helical pitch bar is a hollow pipe, and the part that the described first helical pitch bar is positioned at the air bag cavity has passage, the interior tube chamber of the inner chamber of described passage communicated air bags and the first helical pitch bar, and the end that the described first helical pitch bar stretches out pressing plate is communicated with air inlet pipe.

Have projection on the described pressing plate, described projection is that higher pair contacts with cam.

The junction of the described first helical pitch bar and the second helical pitch bar and pressing plate is provided with sealing ring.

Beneficial effect: this utility model adopts said structure, has the following advantages:

(1) simple in structure, light weight, volume are little, are easy to carry.

(2) cheap, be convenient to popularize, can substitute main equipment in a lot of areas underdeveloped.

This utility model is simple in structure, easy to use, has higher use value and promotional value.The utility model is described in further detail below in conjunction with drawings and Examples.

Description of drawings

Accompanying drawing is the structural representation of this utility model embodiment.
