Detailed Description
The nursing bed for the patient is only used for a short time, and the nursing bed for the patient needs a long time; some patients can not move independently at all, some can move independently partially, some patients have serious illness and some patients have mild illness, and other patients need special care. The nursing bed is used in a hospital, the external condition is better, the using object is uncertain, and the needed functions are more; the inflatable nursing bed is designed to have various functions according to different requirements of different patients, and can be selectively combined according to requirements. The mattress of the nursing bed can adopt a common soft mattress or an air mattress (an integral air bag or a combined air bag); the inflation gas source is divided into a common gas source and a transduction gas source, and the control mode can be wired or wireless.
The pneumatic system of the multifunctional inflatable nursing bed is mainly a carrier for changing the pressed part of the body of a patient when the body of the patient lies horizontally, and in order to overcome the defects of the existing inflatable mattress, gas with proper temperature is used as a gas source for inflating an air bag. The pneumatic system of the multifunctional inflatable nursing bed comprises an inflatable mattress, a compression pump, an inflatable electromagnetic valve component, an air return electromagnetic valve component, an air discharge electromagnetic valve, an air supply electromagnetic valve, a heating element, a refrigerating element and a transduction container.
The structure of the air mattress is divided into two categories: 1. the whole air bag cushion is a big air bag; 2. the combined air bag cushion is composed of a plurality of small air bags. In the combined air bag mattress, a plurality of small air bags can be divided into a plurality of groups according to requirements, and different combinations are adopted for inflation and deflation. The length of the small air bag can be the width of the mattress, and the mattress is generally used in a whole bed and four transverse beds; the length of the small air bag is half of the width of the mattress in the two-long-plate bed and the eight-plate combined bed, the mattress is divided into a left area and a right area, and the mattress does not influence the inflation and return air flow of the air bag when a patient turns on the left side and the right side. The more the air bags of the mattress are divided into groups, the stronger the nursing function is, but the more the number of the required inflation tubes and air return tubes and the more the control elements are, the more the processing is complicated, so that the mattress is preferably divided into 2 to 4 groups from the practical idea.
In order to provide the air with proper temperature and pressure for the mattress, the air can be used as an ice blanket and a heat blanket if necessary, and the transduction container is used as an air buffer to heat or refrigerate the air. The transduction container is used as a storage container of compressed gas, a heating element and a refrigerating element are arranged in the transduction container, and the gas in the container is subjected to temperature regulation in advance according to actual requirements to reach a set temperature. The air inlet end of the compression pump is provided with an air return electromagnetic valve component and an air supply electromagnetic valve, the air outlet end of the compression pump is connected with a transduction container, and the transduction container is provided with an air inflation electromagnetic valve component and an air deflation electromagnetic valve. The compression pump sucks gas from the gas return electromagnetic valve component and the gas supplementing electromagnetic valve and inputs compressed gas to the energy conversion container; the compressed gas in the transduction container is directly heated or cooled by a heating element or a refrigerating element. A certain amount of water can be added into the transduction container, the heating element and the refrigerating element are positioned below the water level, and the water is used as an intermediate medium to generate hot air or cold air so as to keep the pressure and the temperature of the gas in the transduction container stable. If the temperature is adjusted by water, the transducer container is additionally provided with elements such as a water inlet valve, a water discharge valve, a water level detection probe and the like. The temperature-regulated compressed gas in the transduction container is discharged by the inflation solenoid valve assembly and the deflation solenoid valve. The air inflation electromagnetic valve component is connected with one end (an air bag inlet) of an air bag of the air mattress through an air pipe, and sends the air in the transduction container into the air bag; the air return electromagnetic valve component is connected with the other end (air outlet of the air bag) of the air bag of the inflatable mattress through an air pipe, and the air in the air bag is pumped back into the energy conversion container through the compression pump. Under normal conditions, gas circularly flows in the transduction container and the air bag, and when the gas pressure in the transduction container is greater than the set pressure, redundant gas in the transduction container is discharged through the air discharge electromagnetic valve; when the gas pressure in the transduction container is smaller than the set pressure, the gas is supplemented into the transduction container through the gas supplementing electromagnetic valve, so that the pressure in the container reaches the set pressure. The air supply solenoid valve and the air discharge solenoid valve are used for adjusting the amount (pressure) and the set pressure of gas in the energy conversion container, do not work basically in normal work, and the gas circularly flows in a sealed environment. When the air-supply device is used, no air exists in the container and the air bag, the amount of air to be filled is large, if the caliber of the air-supply electromagnetic valve is small, an air-supply valve (a manual valve can be adopted) can be specially added for accelerating the air-supply speed. When the air-conditioning system is not used, the air in the transduction container and the air bag needs to be completely exhausted, the air-bleeding electromagnetic valve is utilized, and the air-bleeding valve (which can adopt a manual valve) can be additionally arranged to accelerate the air-bleeding speed.
In order to reduce the temperature difference between the air inlet and the air outlet of the air bag and keep the temperature of the whole air bag cushion balanced, particularly when the pressure of the air bag reaches a set pressure and the pressure in the air bag is equal to the pressure in the transduction container, the inflation electromagnetic valve is closed, the gas stops flowing, and the temperature of the air bag possibly has a large difference. In order to ensure the temperature stability of the inflatable mattress, the electromagnetic valves in the inflatable electromagnetic valve component and the air return electromagnetic valve component adopt electromagnetic valves with adjustable opening sizes, and the compression pump adopts a compression pump with adjustable rotating speed. Arranging a temperature detector at the air return end, detecting the temperature of the return air, and comparing the temperature of the return air with the set temperature; by utilizing a feedback technology, according to the difference between the temperature of the air return end and the set temperature, the opening of the electromagnetic valve or (and) the rotating speed of the compression pump is adjusted to adjust the inflation (air return) speed, so that the temperature difference of the airbag cushion is adjusted, namely, when the pressure of the airbag and the pressure in the transduction container reach balance, the compression pump still works, the inflation electromagnetic valve and the air return electromagnetic valve are simultaneously opened, so that the gas in the airbag flows at a certain speed, and the temperature stability of the airbag cushion is kept.
