Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an automatic pressurization system for a mobile medical bed. Background Technology

[0002] Medical devices refer to instruments, equipment, appliances, materials or other articles used alone or in combination on the human body, including the necessary software; their effects on the human body surface and inside the body are not achieved by pharmacological, immunological or metabolic means, but these means may be involved and play a certain auxiliary role.

[0003] Current medical air mattresses often only serve the purpose of providing sleeping comfort for medical patients, and their function is relatively simple. During the recovery phase after surgery, in order to reduce the impact on the wound, doctors often advise patients not to move their bodies too much. However, some patients may cause their wounds to reopen due to habitual movement after falling asleep, which will affect their recovery. Therefore, we have proposed an automatic pressurization system for a mobile medical bed to solve the above-mentioned problems. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic pressurization system for a mobile medical bed.

The pressure sensors are electrically connected to a controller, and the controller is electrically connected to the air pump.

[0011] Preferably, the top of the movable seat is provided with a second sliding groove, the second sliding groove is slidably connected to a sliding rod, the bottom of the sliding rod is fixedly installed with a ground plate, and the sliding rod is sleeved with a first spring.

[0012] Preferably, the shock absorption assembly includes two symmetrically arranged telescopic rods, each telescopic rod is fitted with a second spring, a limit plate is fixedly installed on the top of the second spring, the limit plate and the telescopic rod are fixedly connected, the top of the telescopic rod is fixedly connected to a connecting plate, and the bottom of the telescopic rod is fixedly connected to the top of the mounting base.

[0013] Preferably, the sliding assembly includes a guide rail, the bottom of which is fixedly connected to the bottom of the mounting cavity, and a slider is slidably connected to the top of the guide rail, the top of which is fixedly connected to the bottom of the clamping plate.

[0014] Preferably, the bottom of the movable seat has multiple wheels arranged in a rectangular pattern, and the wheels are brake swivel wheels.

[0015] Preferably, the rotating assembly includes a protrusion, the bottom of which is fixedly connected to the top of the mounting base. A first rotating shaft is fixedly mounted on one side of the protrusion. A first connecting rod is rotatably mounted on one end of the first rotating shaft. A rotating rod is rotatably mounted on one end of the first connecting rod. A second connecting rod is rotatably mounted on one end of the rotating rod. A second rotating shaft is rotatably mounted on one end of the second connecting rod. A second protrusion is fixedly mounted on one side of the second rotating shaft. The top of the second protrusion is fixedly connected to the bottom of the connecting plate.

[0016] The beneficial effects of this invention are:

[0017] 1. When a person lies on the air mattress, their head is placed in the head inflatable rubber sleeve, their shoulders in the shoulder L-shaped inflatable rubber sleeve, their hands in the hand inflatable rubber sleeve, and their legs in the leg inflatable rubber sleeve. The inflatable restraint straps can initially fix the person in place. The pressure sensor can detect whether the pressure of the rubber sleeves used to fix the person is sufficient to fix them in place. If the fixation pressure is too low, the controller will start the air pump, which will inflate the air mattress. The air in the air mattress will flow to the rubber sleeves, which will then compress the person. The pressure sensor can test the pressure of the rubber sleeves compressing the person in real time. Once the pressure reaches the specified value, the inflation will stop.

[0018] 2. When the air mattress needs to be moved, place it on top of the connecting block. At this time, the two side trays will swing upward due to the pressure and the rotation axis of the connecting block. The mounting platform will also be under pressure, pressing down on the first spring and causing the sliding rod to press down. The sliding rod pushes the base plate to fit against the ground. The two cylindrical bodies will be under pressure, pressing down on the second spring. The telescopic rod will retract, and the first and second connecting rods will also be under pressure, swinging downward to reduce the impact of the air mattress being suddenly lowered. This completes the placement of the air mattress. When the air mattress needs to be clamped, pull the screw rod to slide it in the first sliding groove, causing the clamping plate to move inward along the guide rail through the sliding hole and the slider, so that one side of the clamping plate fits against one side of the air mattress. Then, turn the screw rod clockwise into the first screw hole to clamp the air mattress. To loosen the clamping of the air mattress, turn the screw rod counterclockwise to unscrew the first screw hole and slide the screw rod to loosen the clamping of the air mattress.

[0019] The inflatable mattress designed in this invention can achieve intelligent inflation, and the inflation can fix the human body, preventing the body from moving during sleep and causing wounds to reopen. At the same time, the movable seat can be combined with the inflatable mattress, making it convenient to move the inflatable mattress. Attached Figure Description

[0042] The working principle and usage process of this invention are as follows: When a person lies on the inflatable mattress 27, their head is placed in the head inflatable rubber sleeve 28, their shoulders in the shoulder L-shaped inflatable rubber sleeve 29, their hands in the hand inflatable rubber sleeve 30, and their legs in the leg inflatable rubber sleeve 31. The inflatable restraint strap 32 can initially fix the person. The pressure sensor can sense whether the pressure of the rubber sleeves used to fix the person is sufficient to fix them. If the fixing pressure is too low, the controller starts the air pump 26, which inflates the inflatable mattress 27. The air in the inflatable mattress 27 flows to the rubber sleeves, which can then compress the person. The pressure sensor can test the pressure of the rubber sleeves compressing the person in real time. Once the pressure reaches a specified value, inflation can be stopped. When it is necessary to move the inflatable mattress 27, the inflatable mattress 27 is placed on top of the connecting block 8. At this time, the two side trays 24 are subjected to pressure and rotate through the connecting block 8. When the rotating shaft swings upward, the mounting platform 7, under pressure, presses down on the first spring 12, causing the sliding rod 10 to press down as well. The sliding rod 10 pushes the base plate 11 to fit against the ground. The two cylindrical bodies 17, also under pressure, press down on the second spring 20, causing the telescopic rod 19 to retract. The first connecting rod 13 and the second connecting rod 15, also under pressure, begin to swing downward, reducing the impact of the sudden drop of the air mattress 27. This completes the placement of the air mattress 27. When clamping the air mattress 27, pull the screw rod 3 to slide it in the first sliding groove 6, causing the clamping plate 4 to move inward along the guide rail through the sliding hole 22 and the slider, so that one side of the clamping plate 4 fits against one side of the air mattress 27. Then, turn the screw rod 3 clockwise into the first screw hole 5 to complete the clamping of the air mattress 27. When loosening the clamping of the air mattress 27, turn the screw rod 3 counterclockwise to unscrew the first screw hole 5 and slide the screw rod 3 to loosen the clamping of the air mattress 27.
