detailed description

In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present utility model, all other implementations obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

Referring to Fig. 1 and Fig. 2, the utility model provides a decubitus pad with temperature regulation, which includes a water tank 3 and a plurality of strip-shaped airbags 1 arranged side by side. Connected, the left end of each airbag 1 is provided with an airbag inlet, the right end is provided with an airbag outlet, and the water tank 3 is provided with a water outlet and a water return port. Each airbag inlet is connected to a water inlet branch pipe 2, and all water inlet branch pipes 2 are free One end is connected with one end of same water inlet main pipe 5, and the other end of water inlet main pipe 5 is connected with the water outlet on the water tank 3, and water pump 8 is installed on the water inlet main pipe 5.

Each airbag 1 is in the initial state, the airbag 1 is in a shriveled state, and water with a suitable temperature is stored in the water tank 3, and the water pump 8 on the water inlet main pipe 5 is started to work, and the water pump 8 in the water tank 3 is injected into each airbag 1, and the airbag 1 will form water waves, the formation of water waves can firstly change the patient's oppressed parts and prevent the occurrence of decubitus. In addition, because the water in the air bag 1 has a certain temperature (controlled between 10-25°C in summer, In winter, it is controlled between 40-50°C), so it can absorb the heat of the patient's body or transfer the heat to the patient's body, so as to ensure that the patient is in a more suitable temperature and improve the comfort of the patient.

Each airbag outlet is connected with a return water branch pipe 6, and the free ends of all return water branch pipes 6 are connected with one end of the same return water main pipe 4, and the other end of the return water main pipe 4 is connected with the water return port on the water tank 3 , water pump 8 is also installed on the water return main pipe 4.

When the water in the air bag 1 needs to be discharged, the water pump 8 on the return water main pipe 4 will be turned on, and the water in the water bag will be drawn out and sent back to the water tank 3, so that the water pump 8 on the water inlet main pipe 5 and the return water The water pump 8 on the main pipe 4 is turned on and off alternately, so that the air bag 1 can be filled and discharged alternately.

Each water inlet branch pipe 2 and each return water branch pipe 6 are equipped with a valve 7, each valve 7 can control the on-off of the corresponding branch pipe, and also includes a controller, the controller is electrically connected with each valve 7, convenient The closing or opening of the corresponding valve 7 can be controlled by the controller.

To put it simply, the water pump 8 on the water inlet main pipe 5 and the water pump 8 on the return water main pipe 4 are always on. If it is necessary to control a certain air bag 1 to fill with water, the valve on the return water branch pipe 6 of the air bag 1 7 is closed under the control of the controller, and the valve 7 on the water inlet branch pipe 2 of the airbag 1 is opened under the control of the controller, so that the airbag 1 can be filled with water, otherwise, the water in the airbag 1 is drawn out .

Therefore, the controller can control the opening of the valve 7 on the water inlet branch pipe 2 corresponding to the air bag 1 corresponding to the water-filled air bag 1 (the valve 7 on the corresponding return water branch pipe 6 is closed) by controlling the valve 7, and the water in the air bag 1 needs to be turned off. When the water is drawn out, the valve 7 on the corresponding return water branch pipe 6 of the corresponding air bag 1 is controlled to open (the valve 7 on the corresponding water inlet branch pipe 2 is closed).

The inventor considers that the patient's back will feel cold on the back under the effect of the decubitus pad when used in winter, so the thermal insulation performance of the patient's back is not ideal.

A heater and a temperature acquisition sensor are installed in the water tank 3, and the collection point of the temperature acquisition sensor is located in the water tank 3, and both the heater and the temperature acquisition sensor are connected to the controller.

Under winter conditions, the temperature acquisition sensor collects the actual temperature of the water in the water tank 3, and transmits the temperature signal to the processor. If the water temperature is lower than 40°C, the controller changes to control the heater to work, so that the water temperature in the water tank 3 It is controlled between 40-50° C., so that after the water is sent into the air bag 1, the heat in the water will be transferred to the patient, which acts as an electric blanket.

Of course, in summer, it is necessary to cool down the back of the patient. In the same way, the relatively low temperature water can be sent into the air bag 1, and in order to reduce the temperature of the water in the water tank 3, the utility model also makes the following improvements:

A semiconductor cooling sheet is installed in the water tank 3, and the semiconductor cooling sheet is electrically connected to the controller. The controller controls whether the semiconductor cooling sheet is working or not according to the temperature signal collected by the temperature acquisition sensor, so as to ensure that the water temperature in the water tank 3 is controlled at (10- 25°C).

It should be emphasized that in actual use, the selection of the specific water temperature control interval can be set manually, and the above is just an example.

The controller can generally adopt PLC or single-chip microcomputer, and its specific model is not limited here, as long as it can receive temperature signal data and send out electrical signals.

Also offer on the water tank 3 and change the water port, and be plugged with plugging cover on this water change port.

The inventor considers that the water in the water tank 3 needs to be replaced regularly, and by setting the water exchange port, it is convenient for the replacement of the water in the water tank 3 to prevent the growth of harmful substances in the water.

The water pump 8 on the water inlet main pipe 5 and the water return main pipe 4 is a miniature water pump 8, and the volume sent by the miniature water pump 8 during work is low, which can not affect the patient's rest, and secondly, the cost of the miniature water pump 8 is relatively low.

The number of airbags 1 is 18.

It should also be noted that there is a detachable connection between the water inlet branch pipe 2 and the water inlet main pipe 5, so that the water inlet branch pipe 2 and the water inlet main pipe 5 can be easily separated, and all the water inlet branch pipes 2 and one The air intake pipe is connected, and the other end of the air intake pipe is connected with an air pump, through which each air bag 1 can be inflated, that is to say, when the utility model needs to be inflated, it can be inflated only by replacing a part of the parts, realizing the inflating and inflating Free switching of water.

Of course, when inflating, it is also necessary to separate the return water branch pipe 6 from the return water main pipe 4, that is to say, the return water branch pipe 6 and the return water main pipe 4 are also detachably connected.

Some massage points can also be set on the upper side of the airbag 1, so that when the airbag 1 bulges, the patient's back can be massaged, especially in summer, the clothes worn by the patient are less, and the effect is more obvious, which plays a role in improving the patient's health. Health effects.

It should be emphasized that the utility model is not limited to the use in winter and summer, such as postoperative patients who need to warm up or need to maintain hypothermia to reduce the basal metabolic rate (such as patients after cardiopulmonary resuscitation, etc.) ) state, the utility model can be used as an insulated water bed or a cooling water bed.

In actual use, it is only necessary to apply the above-mentioned pressure sore pad with temperature regulation on the hospital bed, the pressure sore pad body (18 airbags 1 arranged side by side) is laid on the bed body, and the water tank 3 is arranged on the lower side of the bed body That's it.

In this way, when the patient lies on the hospital bed, the occurrence of bedsores can be prevented, and the water temperature can be controlled to prevent the patient from overheating or overcooling.

The above is only a specific embodiment of the present utility model, but the scope of protection of the present utility model is not limited thereto. Anyone familiar with the technical field can easily think of changes or changes within the technical scope disclosed by the utility model Replacement should be covered within the protection scope of the present utility model.
