Description

Photoinductor support for medical air bed control of air pressure

The invention relates to a support frame, in particular to a photoinductor support frame for controlling air pressure in a medical air bed. The structure of the placement base is improved to increase the stability of the photoinductor. Integrated structure makes disassembly easy.

The global population has entered the age of aging, the number of elderly people has increased dramatically in various countries, and there are more and more issues about how to protect and care for the daily life of the elderly. There are also some people in daily life who have difficulty moving due to serious illness. When forced to stay in bed, medical air bed is specially provided for patients who must stay in bed for a long time or cannot turn over by themselves. Patients who stay in bed for a long time or cannot turn over by themselves have their skin locally under pressure, friction, shear, gravity Factors such as humidity and humidity cause poor blood circulation there, resulting in localized skin ulcers, skin peeling, and necrosis, and eventually bedsores are formed. Medical air cushion beds use intermittent inflation to keep the mattresses inflated. Some bed tubes have no air to reduce the pressure of the patient's contact with the mattress, in order to achieve a decompression effect and avoid the occurrence of bedsores.

The general medical air bed host has a poor design of the fixed support of the photo sensor. It is not only costly to manufacture, but also difficult to maintain and difficult to install and disassemble. As shown in Figures 6 and 7, the medical air bed is used to control air pressure. The photo sensor is fixedly supported by a support frame formed by three parts, which are a bottom plate 60, a side fixing seat 62 and a placing seat 64, which are designed in the main body casing. The upper part is connected to the lower cover of the main body casing; the bottom The plate 60 is made of metal. The bottom plate is provided with a through hole 601 which is penetrated by a rotating shaft 72 provided on a motor rotating base 70. The rotating shaft 72 is combined with an air distribution plate 76, and the air distribution plate 76 and the An elastic member 74 is sleeved between the bottom plates 60 on the rotating shaft 72. The side fixing seat 62 is also made of metal and is formed by a flat U-shaped piece 621. The side fixing seat 62 is a screw. It is fixed to the bottom plate 60 in a locking manner, and one of the air distribution pipes 761 provided on the air distribution plate 76 is located on the U-shaped piece 621 of the side fixing seat 62; Receiving grooves 641 extend symmetrically from the two sides of the accommodating grooves 641. Each of the clamping abutting members 642 has a hook 643 opposite to each other, and a photodetector 80 can be installed in the accommodating space. The groove 641 is fixed by each of the clip abutting members 642.

However, the bottom plate 60 and the side fixing seat 62 are stamped from a metal material to make the manufacturing cost higher; the elastic member 74 sleeved on the rotation shaft 72 is prone to deflection and is not easy to fix; The U-shaped sheet body 621 on the side fixing base 62 is flat, and it is easy to be distorted during the actual assembly process, and the end customer is also difficult to repair and disassemble. In addition, the optical sensor 80 is accommodated in the At the top of the receiving groove 641, the photodetector 80 is fixed only by the clips 642, which will shake back and forth to cause loosening, so there is still room for improvement in conventional technology.

The invention discloses a photoinductor support frame for controlling air pressure in a medical air bed, which includes a base plate made of plastic material and formed integrally, a side fixing seat and a placing seat. The base plate is provided with a through hole. A raised arc lead angle is formed on the through hole; the side fixing seat is arranged on the bottom plate, and has two cylinders with a space between each other, and a catch is arranged between the bottoms of the cylinders. The placing seat is arranged on the bottom plate, and a placing groove is opened on a side different from the bottom plate. A supporting surface is set on the top of the placing groove, and the supporting surface is recessed with a first gap in the direction of the bottom plate. Two sides of the supporting surface respectively face a side different from the bottom plate, and a clamping piece is convexly arranged, the clamping pieces are parallel to the bottom plate, and a second gap is recessed on the opposite side of the clamping pieces. The free end of each of the clip abutting members is a hook provided opposite to each other, and a block-shaped support member is protruded at a certain distance from the supporting abutment surface on the inner wall surface of the placing slot, and each of the block-shaped support members is correspondingly disposed on Below the first gap and the second gaps.

With the above structure, the advantages of the present invention are as follows:

1. The bottom plate, the side fixing seat and the placing seat are made of plastic, which can reduce the manufacturing cost.

2. The arc lead angle provided on the bottom plate can be set by an elastic member to stabilize the position of the elastic member and make the assembly process smoother.

3. The side fixing seat is integrally formed with the bottom plate and the placing seat, so there is no problem of falling components, the assembly process is convenient, and the columns can provide better support and stability. Not easy to skew.

4. The clips of the placement base are disposed on a side different from the bottom plate, in other words, the clips are provided on the side of the placement base, and the placement base has the block-shaped support members, Both ends of a photosensor can be clamped on the abutment surface and the block-shaped supports, respectively, and the clips can be used to fix the photosensor to the placement base, which can further improve the The swaying problem of the photo sensor back and forth reduces the possibility of loosening the photo sensor.

5. A connecting plate may be provided between the side fixing base and the placing base to strengthen the bonding strength of each other. Similarly, a plurality of connecting supporting bases may be provided between the placing base and the bottom plate to increase the bonding strength. degree.
