The five-way ball valve has five connecting ports in total, one of the five connecting ports is a main air inlet, the other four connecting ports are air outlets, and the ventilation condition of the air outlets is adjusted by screwing a control handle of the five-way ball valve, so that the on-off condition is controlled without a plurality of switch valves, and the clinical operation steps are simplified.
In the present embodiment, the volumes of the four chambers 12 are the same, and the separation membrane has a cross-shaped structure, so that a relatively square structure can be formed, and the control can be performed clinically. Of course, the number of chambers is not limited to four, but four chambers can form two inflatable chambers on the diagonal, which can be satisfied for a particular support location; even one of the chambers is sometimes only needed to be inflated for supporting, so the design of a plurality of chambers is more in line with clinical requirements.
In the embodiment, the chambers close to one side of the five-way ball valve 5 are marked as a first chamber 121 and a second chamber 122, the chambers far away from one side of the five-way ball valve 5 are marked as a third chamber 123 and a fourth chamber 124, and the air ducts of the third chamber 123 and the fourth chamber 124 respectively pass through the first chamber and the second chamber and extend out to be connected with the air outlet of the five-way ball valve; since the balloon itself forms an integral body and the individual control of the chambers necessitates multiple conduits, if all the conduits are externally extended, the balloon will increase its volume within the body and interfere with other tissue organs; the airway tube should be arranged to extend in one direction and the airways of different chambers converge and extend from one location, so that the airway tube of the chamber located inside must pass through other adjacent chambers and therefore can extend from one location, facilitating manufacture and clinical use.
In the embodiment, the tail ends of the four air ducts 2 are provided with first magnetic suction rings, the air outlet of the five-way ball valve 5 is provided with a magnetic suction sleeve corresponding to the first magnetic suction rings, and the first magnetic suction rings are communicated with the magnetic suction sleeve in a suction manner; therefore, in the process of clinical use, the air guide pipe and the five-way ball valve can be directly and quickly butted under the action of magnetic attraction, so that a stable air guide connecting structure is formed, and the five-way ball valve is provided with four air outlets and one air inlet, so that the air guide connecting structure is not limited by specific caliber and can be quickly connected in place by the magnetic attraction structure; at the same time; the corresponding air outlets and the air guide pipes corresponding to the chambers can be marked with numbers, the air guide chambers corresponding to the air guide pipes are marked with the numbers, and the switches of the five-way ball valves are also marked, so that doctors can conveniently and correspondingly inflate the air guide pipes during clinical operation.
In the implementation, the parts of the four air ducts 2 extending out of the air bag are respectively provided with an air discharging pipe 21, and the air discharging pipes are provided with sealing plugs; in order to meet the requirement of quick deflation, the air release pipe is arranged for deflation, and the air pressure of the cavity is adjusted by utilizing the air release pipe; as a more preferable scheme, one ends of the four air discharging pipes, which are far away from the air guide pipe, are combined into a main air discharging pipe, and the main air discharging pipe is used for simultaneously discharging air in the cavity; because in some emergency, in order to better guarantee the life safety of the patient, all the gas in the air bag needs to be emptied immediately, all the gas in the four cavities needs to be released simultaneously, and a plurality of gas release pipes will waste some time.
The use process comprises the following steps: before operation, a doctor confirms a chamber needing inflation according to the requirement of a liver turning position, puts a completely shriveled air bag into a preset position, connects an air guide pipe of the chamber needing inflation with an air inlet of a five-way valve, does not connect other chambers needing inflation, grips a hand to hold an inflatable ball to inflate, and utilizes an air release pipe to carry out air pressure fine adjustment so as to achieve the most proper supporting position and the most proper supporting air pressure; the anti-skid surface of the inflated air bag is in contact with the surface of the liver to support the inflated air bag, then the inflated air bag is used for doctors to perform operation, and then the inflated air bag is quickly deflated through the main deflation pipe and the air guide pipe when the operation is finished or in emergency.
The invention has the technical effects that:
1. the multi-cavity air bag is adopted, so that different areas can be supported as required, and the supporting height and direction can be adjusted;
