Description

The double thickness air filled mattress bed

Technical field

This utility model belongs to a kind of medical apparatus and instruments, especially the nursing double thickness air filled mattress bed that uses for the long-term bed patient prevents decubital ulcer.

Background technology

At present air fluidized bed on the market all adopts rubber or nylon coated fabric, with boning or whole air mattress that the method for high frequency heat seal is made or the air matting that has some strip air chambers to be combined into.Above-mentionedly realize airtight simultaneously and bear pressure by rubber or nylon coated fabric, the shortcoming of this structure is: the manufacturing process more complicated, and with regard to present technical merit, adhesive force between the air-tightness of rubber or plastic coat fabric and coat and the tissue layer all is difficult to be guaranteed, and the material of this air fluidized bed and manufacturing cost are all than higher.

Summary of the invention

This utility model is that sealant and bearing course are independently made two air chambers, be sleeved on together, fabric pressure-bearing air chamber bears pressure outside, plastics or rubber seal air chamber are airtight in interior realization, form a unit, several unit air chambers link together, and form an air fluidized bed, can be divided into some groups between the air chamber on demand and connect with trachea.

The technical solution of the utility model is that the double thickness air filled mattress bed is characterized in that, comprising:

Inner liner is rectangular piped air chamber and is formed by some, and adjacent described air chamber connects with connecting trachea between any two, thereby forms described inner liner;

Inflation inlet is opened on the described inner liner;

Bearing course, be arranged on described inner liner about.

Another technical scheme of the present utility model is that the double thickness air filled mattress bed is characterized in that, comprising:

Inner liner is rectangular piped air chamber and is formed by some, and described air chamber is divided into some groups, is connected and forms one group of inner liner by connecting trachea between the air chamber on the same group;

Inflation inlet is opened on described every group of inner liner;

Bearing course, be arranged on described inner liner about.

Comprehensively above-mentioned, special character of the present utility model is that bearing course and inner liner be independently double-deck air fluidized bed respectively.

Description of drawings

Below, with reference to accompanying drawing, for those skilled in the art that, to the detailed description of the present utility model, above-mentioned and other purposes of the present utility model, feature and advantage will be apparent.

Fig. 1 is the floor map of this utility model one preferred embodiment;

Fig. 2 is the generalized section of Fig. 1;

Fig. 3 is the generalized section of another preferred embodiment of this utility model.

The specific embodiment

Please in conjunction with Fig. 1,2,3, Fig. 1 is the plane of this utility model double thickness air filled mattress bed bed body, its inside can be referring to section structure shown in Figure 2, is rectangular piped air chamber 10 and is formed an inner liner 1 by some, and each independently has two kinds of connected modes between the strip air chamber 10:

Fig. 2 has provided first kind of mode, promptly with connecting trachea 4 adjacent air chamber 10 is connected in twos, thereby forms an inner liner 1 that connects fully, and in air fluidized bed bed body tip position an inflation inlet 3 is set, and provides source of the gas by outside air pump 4 for air fluidized bed.

Fig. 3 has provided another kind of connected mode, air chamber 10 is divided into some groups, be illustrated as 2 groups, link to each other by connecting trachea 41,42 between the air chamber on the same group, form two groups of inner liners 51,52 that connect, each is organized inner liner 51,52 inflation inlet 31,32 respectively is set, and provides source of the gas by outside air pump 4 for each inner liner 51,52.

In addition, the inner liner 51,52 of the inner liner 1 of above-mentioned first embodiment, second embodiment form a bearing course 2 with a whole lining up and down, make in the position between two 2 air chambers 10 on the bearing course 2 and form lacing wire 6, thereby increase its intensity.The characteristics of this utility model maximum just are that bearing course 2 and inner liner 1 be independently double-deck air fluidized bed respectively.

In this utility model, sealed air chamber can have encapsulants such as rubber or plastics to adopt methods such as bonding or high frequency heat seal to make.The pressure-bearing air chamber can be made by firm natural or synthetic fabrics and form.In addition, air fluidized bed can be made up of the unit air chamber of different size and varying number.

More than all embodiment only for the explanation this utility model usefulness, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or variation, so all technical schemes that are equal to also should belong to category of the present utility model and should be limited by each claim.
