Description

Airbag control device

The present invention "airbag control device" relates to a technical field for controlling different aspects of airbag changes in inflation, maintaining the status quo or exhausting.

An air bed is sold in the market. It is designed to prevent the skin from being used for prolonged compression when the patient is in bed for a long time. This type of air bed is an air pump to inflate the air bed. After the airbed is lying on the patient, the pressure is different according to the patient's body shape, body weight, and the pressure of the air bed corresponding to each part of the human body, so the air bed is mostly designed to be juxtaposed by a plurality of independent airbag strips. Therefore, each airbag strip can adjust the internal air pressure to an appropriate one according to different needs. The pressure regulating structure of the conventional airbag is mostly disposed in the covering structure of the air bed, which is quite troublesome when the pressure is adjusted, and the entire covering structure needs to be opened, and the pressure regulating structure only has two functions of air flow passage or open circuit, and the airbag is used as the airbag. If the internal pressure is too large, or when there is a need for CPR first aid, there is no pressure relief function, resulting in many limitations and defects in the actual use of the air bed.

Obviously, the existing air bed pressure regulating structure is still not ideal and perfect, and it is necessary to improve. In view of this, the creators have specially researched and created the cost case, and can use the proposal of this case to improve the existing shortcomings, so that the pressure regulating function of the air bed can be more perfect and ideal, and meet the actual needs.

In order to improve the functional limitations and lack of the above-mentioned air bed pressure regulation, the main purpose of the creation of the "airbag control device" is to provide a control device which is arranged between the inflatable pump and the airbag to control the airbag change. In the case of inflating, maintaining the status quo or exhausting, the air pressure in the airbag can be supplemented when the pressure in the airbag is insufficient, and the air pressure in the airbag is too large or the CPR emergency can be used to excrete air when the airbag pressure is appropriate or When the air bed needs to be moved, it can be stopped to maintain the status quo; thereby achieving the practical purpose of multi-functionality.

In order to achieve the above object, the specific means of the present invention is as follows: the control device mainly comprises an outer casing and an inner body, wherein the inner system is accommodated in the outer casing and can be rotated, and the outer casing system is arranged in the inflatable pump and Airbags.

The outer casing has a long cylindrical shape, and an inner end surface is an open hollow space. The outer casing body is sequentially provided with a first pipe body, a second pipe body and an exhaust port.

The inner body has a long hollow shape, and the inner body is sequentially disposed with a first opening and a second opening on the same axis, and at the other corresponding surface, a third opening is a fourth opening is located on the same axis, wherein the second opening is in the same cross section as the third opening and the second opening is in a through relationship with the third opening.

After the inner body group is placed in the space of the outer casing, the first opening is in the same cross-sectional relationship with the first pipe system; and the second opening and the third opening are in the same section as the second pipe system Relationship of lines; The fourth opening is in the same hatching relationship as the exhaust port.

The first tube system is used for connection with an inflatable pump, and the second tube system is used for connection with an air bag.

The inner body is provided with a knob at the outermost end; and the first opening, the second opening, the third opening and the fourth opening are respectively disposed with an open oil seal, and the inner body is respectively disposed at each of the first openings, A spacer oil seal is respectively disposed on the side edges of the second opening and the fourth opening.
