[0030] Further, as shown in the figure, Figure 3 The three-way valve 2 comprises a valve body 21 and a valve rod 22; the middle part of the valve body 21 is provided with a valve cavity 24; the side of the valve cavity 24 is provided with three through holes; the valve rod 22 is rotationally connected in the valve body 21; the rotationally connected part of the valve rod 22 is provided with a sealing member; the valve rod 22 is provided with a communication groove 23 at the position corresponding to the through hole; in use, the staff can rotate the valve rod 22 to make the communication hole on the valve rod 22 respectively communicate with the plurality of through holes directly to play the role of switching water injection and drainage and sealing, the communication groove 23 is an L-shaped groove.

[0034] Further, as shown in Figures 1-4As shown, the bottom of the piston barrel 31 is fixed with a first data connector 61; the side of the connecting seat 41 is fixed with a second data connector 62; the first data connector 61 and the second data connector 62 are plug-in connectable; the first data connector 61 is connected with the electronic thermometer 51 through a data connection line; the second data connector 62 is connected with a thermistor 63 through a data connection line; the thermistor 63 is located inside the capsule 11; in this embodiment, when the plug-in piston barrel 31 is pulled out, the first data connector 61 and the second data connector 62 are plug-in connected, so that the electronic thermometer 51 is connected with the thermistor 63; the temperature of the warm saline inside the capsule 11 can be detected by the thermistor 63, so that the staff can know the temperature of the warm saline inside.

[0035] Further, as shown in the figure, Figures 1-3 As shown, the connecting seat 41 is fixed with a positioning seat 72; the piston barrel 31 is fixed with a plug rod 71; the plug rod 71 is plug-in slidably connected with the positioning seat 72; when the plug-in piston barrel 31 is pulled out, the plug rod 71 is inserted into the inside of the positioning seat 72, and then the plug rod 71 and the positioning seat 72 are matched, so that the guiding and fixing effects are achieved, thereby facilitating the connection of the first data connector 61 and the second data connector 62.

[0036] The working principle is that before use, the staff prepares warm saline (non-stop jump bridge or non-stop jump artificial blood pump implantation surgery) or ice saline (cardiopulmonary bypass surgery), then absorbs the saline into the syringe, then connects the end of the syringe with the three-way valve, then places the capsule in the pericardial cavity of the heart apex or the position of the pericardial cavity of the septum, and then pushes the syringe to inject the saline into the capsule. The capsule is connected with the syringe through the flexible tube and the three-way valve. During the injection process, the amount of liquid is adjusted according to the actual needs of the chest size, the height to be lifted, etc. The capsule made of inflatable soft material can avoid the hard compression of the heart by the supporting material such as gauze. When the liquid needs to be discharged, the flexible tube is connected with the drain pipe by controlling the three-way valve, so as to discharge the saline in the capsule. The above setting can ensure good supporting force and convenient adjustment according to the chest size and the height to be lifted, and it is relatively soft, reducing the problem of pressing the heart. Further, the surface of the capsule can be coated with a soft silicone layer to ensure softness, and the silicone layer can ensure biocompatibility with human tissues. The corners of the capsule are arc-shaped transition settings, which can avoid the situation that the convex corners on the surface of the capsule press the heart. The capsule is inflated by injecting saline into it. If the capsule leaks, the saline does not harm the human body. The saline is common in the operating room and is easy to obtain. The staff can rotate the valve rod to make the communication hole on the valve rod directly communicate with the multiple through holes, thereby achieving the functions of switching water injection and drainage and sealing. The communication groove is an L-shaped groove. The saline in the piston cylinder can be pushed into the capsule by pushing the piston rod. During the pushing process, the staff can rotate the screw rod to cooperate with the threaded hole in the middle of the support, so as to accurately control the amount of saline injected into the capsule. Manual pushing of the piston rod throughout the process can lead to excessive or insufficient amount, and repeated adjustment is needed. Further, the diameter of the threaded hole is greater than the diameter of the piston rod, so the piston rod can pass through the threaded hole. This setting can quickly push the piston to obtain a certain expansion of the capsule. Then the screw rod is screwed into the threaded hole. This step is used for adjustment and expansion. The above setting can be used conveniently. It is too cumbersome to use the screw rod to push the piston rod throughout the process. The piston cylinder is connected with the connecting seat by pulling and inserting. The connecting seat is communicated with the three-way valve. The rubber ring is used to improve the sealing effect of the connection. The warm saline for non-stop heart surgery is generally judged by the touch of the skin. This judgment is too subjective and different for each person. If the warm saline is not used in time, its temperature will decrease, and it is difficult to obtain the temperature of the warm saline in time. During the process of the embodiment, the electronic thermometer detects the temperature of the warm saline in the piston cylinder by the probe, so as to facilitate the staff to judge whether the temperature of the warm saline is too high or too low.The first data joint and the second data joint are plug-in connected to connect the electronic thermometer with the thermistor, and the temperature of the warm saline in the capsule can be detected by the thermistor, so that the staff can know the temperature of the warm saline in the capsule, and when the plug-in piston barrel is pulled out, the plug rod is inserted into the positioning seat, and then the plug rod and the positioning seat are matched, so that the plug rod can guide and fix the first data joint and the second data joint.
