However, in actual use, due to the different endocrine systems of patients, when treating patients with more viscous sputum, it is often necessary to dilute the sputum with physiological saline and then adsorb it. During this process, the sputum suction tube needs to be pulled out. Frequent extraction and insertion of the sputum suction tube will also cause damage to the patient's respiratory tract. At the same time, general collection devices are installed on the sputum suction device by threads or screws, which is difficult to disassemble quickly, which invisibly increases the labor intensity of medical staff and has certain disadvantages. Therefore, there is an urgent need for a cardiovascular surgical sputum suction device to solve this problem. Summary of the invention

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] When the sputum suction machine is in operation, the guide rod rotates, and when the guide rod rotates, the movable seat drives the guide rod to move the top plate left and right. At this time, the position of the sputum suction plate in the inner cavity of the sputum suction machine will continue to change. When the sputum suction plate moves from left to right in the sputum suction machine, the volume of the left cavity of the sputum suction machine continues to increase. At this time, under the pulling force of the reset spring, it is difficult for the plug to pass through the through groove and enter the inner cavity of the sputum suction machine. At this time, the through groove will be in a blocked state, and the one-way air valve arranged at the connection between the sputum suction machine and the earmuff, at this time, as the sputum suction machine continues to move to the right, a negative pressure state can be gradually formed in the inner cavity of the left side of the sputum suction machine, that is, the sputum suction nozzle is inserted into the patient's throat at this time, and the sputum in the patient's throat can be sucked out by the setting of the sputum suction nozzle.

[0021] 2. In the present invention, when the suction plate moves from left to right in the suction device, the top plate will also pull the extrusion rod to move the extrusion plate toward the right side of the inner cavity of the extrusion cylinder. As the volume of the cavity on the right side of the extrusion cylinder continues to decrease, the pressure of the internal saline solution continues to increase. Under the action of the one-way water valves in different directions of the inner cavities of the input tube and the output tube, the saline solution in the cavity on the right side of the extrusion cylinder will enter the infusion tank through the output tube, and finally be sprayed out from the atomizing nozzle and sprayed on the patient's throat in the form of mist droplets, thereby preventing the sputum from being too viscous, so as to improve the efficiency and quality of the entire device in sucking the sputum from the patient's throat.

[0022] 3. After the invention completes the collection of sputum from the patient's throat, the medical staff can start the electric push rod to make the rotating seat sink downward. Since the rotating seat is rotatably connected to the sputum suction device through the connecting ear, the left side of the sputum suction device will be tilted upward. After that, the medical staff only needs to pull the collection bottle outward with a small force to make the locking block withdraw from the locking groove on the collection bottle. At this time, the collection bottle and the discharge tube will be disconnected, and the medical staff can quickly take the collection bottle, extract and analyze the sputum components in the collection bottle, and clean the collection bottle, which greatly improves the work efficiency of the medical staff.

A pressure relief hole 911 is opened on the left side wall of the extrusion cylinder 91.

[0048] When the present invention is implemented specifically, a controller and a power supply module are also provided. The controller is communicatively connected with the suction motor 78 and the electric push rod 84. The controller is also connected with a control panel with control buttons, a storage module and a clock module. The control panel is used to control the start and stop of the entire suction device, and can independently control the operation of the suction motor 78 and the electric push rod 84. The power supply module is a rechargeable battery or an external municipal power supply. In addition, a computer program can also be entered into the storage module so that the suction device can perform suction operations according to a specific process.

[0049] Working principle:

[0050] When the whole device is used, the whole device can be directly placed on the sundry table next to the patient's bed. The sputum suction device is started by the control button on the control panel. The controller regularly starts the sputum suction motor 78 according to the program stored in the storage module. For example, the sputum suction motor 78 is started once every 2-3 hours, and the running time does not exceed 15S. By starting the sputum suction motor 78, the lead screw 76 rotates. Under the limit constraint of the front side wall of the sputum suction device 1 on the movable seat 77, when the lead screw 76 rotates, the movable seat 77 will drive the guide rod 79 to move the top plate 74 left and right. Since the sputum suction plate 71 is fixedly connected to the top plate 74 through the connecting rod 72, the position of the sputum suction plate 71 in the inner cavity of the sputum suction device 1 will constantly change.

[0051] When the sputum suction plate 71 moves from left to right in the sputum suction device 1, the volume of the left cavity of the sputum suction device 1 increases continuously. At this time, under the pulling force of the return spring 13, the plug 14 is difficult to pass through the through groove 11 and enter the inner cavity of the sputum suction device 1. At this time, the through groove 11 will be in a blocked state, and the one-way air valve 15 is arranged at the connection between the sputum suction device 1 and the earmuff 2. At this time, as the sputum suction device 1 continues to move to the right, the left inner cavity of the sputum suction device 1 can gradually form a negative pressure state, that is, the sputum suction nozzle 6 is inserted into the patient's throat at this time, and the sputum in the patient's throat can be sucked through the setting of the sputum suction port 631. Since the one-way air valve 15 is arranged in the middle position of the side wall of the sputum suction device 1, the sucked sputum will enter the discharge pipe 4 under the left and right of gravity and be stored in the collection bottle 82. That is, at this time, the whole device will complete the function of sucking sputum from the patient's throat;

[0052] When the sputum suction plate 71 moves from left to right in the sputum suction device 1, the top plate 74 will also pull the extrusion rod 93 to move the extrusion plate 92 toward the right side of the inner cavity of the extrusion cylinder 91. As the volume of the right side cavity of the extrusion cylinder 91 continues to decrease, the pressure of the internal physiological saline continues to increase. Under the action of the one-way water valves in different directions of the inner cavities of the input tube 95 and the output tube 96, the physiological saline in the right side cavity of the extrusion cylinder 91 will enter the infusion tank 31 through the output tube 96, and finally be sprayed out from the atomizing nozzle 613, and sprayed on the patient's throat in the form of mist droplets, thereby preventing the sputum from being too viscous, so as to improve the efficiency and quality of the entire device in sucking the sputum in the patient's throat.

[0053] When the sputum suction plate 71 moves from right to left in the sputum suction device 1, the volume of the left cavity of the sputum suction device 1 is continuously reduced, and the air in the left cavity of the sputum suction device 1 cannot be discharged from the one-way air valve 15 through the one-way air valve 15 provided at the connection between the sputum suction device 1 and the earmuff 2. At this time, the air in the left cavity of the sputum suction device 1 can break through the elastic force of the return spring 13, so that the plug 14 is exposed to the outside of the through groove 11, and the through groove 11 is in a conducting state. After the air in the left cavity of the sputum suction device 1 is completely discharged, the sputum suction plate 71 will be in the initial position of the sputum suction device 1, and prepare for the next work;

[0054] When the sputum suction plate 71 moves from right to left in the sputum suction device 1, the top plate 74 will also pull the extrusion rod 93 to move the extrusion plate 92 toward the left side of the inner cavity of the extrusion cylinder 91. As the volume of the right side cavity of the extrusion cylinder 91 continues to increase, the internal saline pressure continues to decrease. Under the action of the one-way water valves in different directions of the inner cavities of the input tube 95 and the output tube 96, and the effect of the external atmospheric pressure squeezing the saline in the liquid storage cylinder 5, the saline in the liquid storage cylinder 5 will enter the right side cavity of the extrusion cylinder 91 through the input tube 95, thereby replenishing the capacity of the saline and preparing for the next throat moisturizing.

[0055] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
