[0002] Smart nursing beds play a vital role in modern operating rooms. These beds are equipped with advanced electric drive systems and sensors that monitor the patient's vital signs and automatically adjust the position and height to suit different surgical needs. Their modular design allows for rapid reconfiguration to accommodate a variety of medical procedures. The integrated technology of smart nursing beds not only improves the safety and efficiency of surgery, but also enhances patient comfort, reduces intraoperative risks, and improves the overall quality of medical care.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figures 1 to 7 The present invention provides a technical solution for an intelligent nursing bed that prevents patients in an operating room from falling:

[0031] An intelligent nursing bed for preventing patients in an operating room from falling, comprising:

[0032] The anti-fall nursing bed 1 is mainly composed of an electric drive system, sensors such as pressure, weight, and temperature sensors, a control system, and an Internet connection function;

[0033] The anti-fall nursing bed 1 includes a bed body 11, which has the ability to push up and a variety of monitoring and detection modules, and the upper driving end is fixed to the bed frame 121, the bed frame 121 is composed of three parts: legs, abdomen and chest, and the parts are rotatably connected and fixed by bolts at the transfer nodes. The upper surface of the bed frame 121 is fixedly provided with a mattress 12, and the upper surface of the mattress 12 is symmetrically provided with two open clamping pad grooves 124 along the center, and the inner part of the clamping pad groove 124 is rotatably provided with a limit pad 122;

[0034] The inside of the mattress 12 and the bed frame 121 are provided with a pneumatic airway 1211 on the right side of the two cushion grooves 124, from the lower side of the right side of the bed frame 121 to the axial hole on the right side of the cushion groove 124, and the input end of the pneumatic airway 1211 is fixedly connected with a pipeline, and is connected to the air pump 123 installed on the right side of the bed body 11 through the pipeline, so as to perform air supply to the inside of the pneumatic airway 1211. The inside of the bed frame 121 is provided with a pneumatic airway 1211 on the path opened by the pneumatic airway 1211. The through square hole cuts off the pneumatic airway 1211, and a liquid cooling box 1217 storing cold liquid is installed inside the square hole, and an air guide body for re-opening the pneumatic airway 1211 is integrally arranged inside the liquid cooling box 1217, and a valve seat 1214 is integrally arranged inside the pipeline of the pneumatic airway 1211 near the right end of the rotating shaft of the limit pad 122, and a trumpet-shaped valve hole is opened at the center of the valve seat 1214, and the expansion is in the opposite direction of the gas flow, and the pneumatic airway 1211 is connected to the airway 1211. The interior of valve seat 1214 is movably connected to conical valve stem 1212 through a plurality of limiting springs 1213 at the expanded side of valve seat 1214. Conical valve stem 1212 is composed of a gyro body and a porous slide plate. Initially, the tip of the gyro body is inserted into the interior of valve seat 1214, and the tip of the gyro body extends through valve seat 1214 along the air flow direction. The extended end of valve seat 1214 is set as a ball end, and the ball end is always in movably contact with driving cone 1215. The bottom surface of driving cone 1215 is in contact with the sliding device. The spring rod 1216 disposed inside the mattress 12 is fixed. The spring rod 1216 is composed of a T-shaped column and a spring sleeved on the column. The column is limited by the spring for sliding. The upper end of the column extends to the space where the rotation shaft of the limiting pad 122 is located and is in active contact with a convex gear body 1223 fixed to the shaft end of the limiting pad 122. The convex gear body 1223 is composed of a ratchet and a cam wheel sleeve rotatably sleeved on the ratchet. The cam and the spring rod 1216 are in alternating active contact.

[0035] The ends of the rotating shaft of the limiting pad 122 are fixed to the convex gear body 1223 and the torsion spring 1224 respectively. The bottom of the limiting pad 122 is symmetrically provided with two piston push rods 1226 along the center line through a movable connecting piece. The piston end of the piston push rod 1226 is sealed and slidably arranged inside the gas rod 1225, and the sliding limit inside the gas rod 1225 is performed by a sleeve spring 1227 sleeved on the rod body of the piston push rod 1226. The oblique lower end of the gas rod 1225 is movably positioned on the surface of the bed frame 121 through a connecting piece, and the gas rod 1225 is movably positioned on the surface of the bed frame 121 through a connecting piece. An interface connected to the inside of the gas rod 1225 is integrally provided on the side of the rod 1225 near the lower end, and the two gas rods 1225 are connected through a connecting air pipe 1228 connected between the interfaces. A retractable branch pipe is integrally connected to the middle position of the side of the connecting air pipe 1228, and the branch pipe is connected to the pneumatic airway 1211 located on the output side of the valve seat 1214 through the opened pipeline. A one-way valve is arranged in the pneumatic airway 1211 between the valve seat 1214 and the convex gear body 1223.

[0036] When working, the air pump 123 is powered on to suck air into the pneumatic airway 1211. The air is cooled by the liquid cooling box 1217 and flows in the pneumatic airway 1211. It passes through the conical valve stem 1212 and the valve seat 1214 and enters the connecting air pipe 1228. Then it is diverted to the air rod 1225. The airflow pushes the piston push rod 1226 to turn the limit pad 122 out and position the human body. At this time, the operation can be performed. If the patient falls to one side, the body presses the surface of a limit pad 122, causing the limit pad 122 to rotate and move downward. The rotating limit pad 122 drives the convex gear body 1223 to rotate. The cam structure on the side of the convex gear body 1223 pushes the spring rod 1216. The spring rod 1216 compresses the spring and moves downward, pushing the driving cone 1215 to move downward. The driving cone 1215 pushes the conical valve stem 1212 to move in the opposite direction to the valve seat 1214 while stretching the limiting spring 1213. The open area between the conical valve stem 1212 and the valve seat 1214 increases, the air flow increases, the amount of gas entering the connecting air pipe 1228 and the air rod 1225 increases, the internal air pressure of the air rod 1225 increases, and the piston push rod 1226 has a stronger pushing force on the limit pad 122, thereby improving the positioning and supporting capabilities for the human body and preventing the patient from falling.

[0037] In summary, through the arrangement of the mattress 12, the bed frame 121, the pneumatic airway 1211, the conical valve stem 1212, the limiting spring 1213, the valve seat 1214, the driving cone 1215, the spring rod 1216, the connecting air pipe 1228, the gas rod 1225, the piston push rod 1226, the limiting pad 122, the convex gear body 1223 and the air pump 123, the air around the nursing bed can be introduced into the pneumatic airway 1211 under the action of the air pump 123, and the introduced gas can be used in a pneumatic form to use the gas rod 1225 and the piston push rod 1226 to perform the limiting pad 122 and the telescopic airbag 1222 to both sides of the patient. The top support can realize effective positioning of the patient on the nursing bed. At the same time, when the patient falls, the tipping force generated by the patient himself can be used to compress the limit pad 122 to reverse and drive the convex gear body 1223 to rotate, so that the convex gear body 1223 pushes the spring rod 1216 and the driving cone 1215, thereby realizing further separation of the conical valve stem 1212 and the valve seat 1214, thereby increasing the area of ​​airflow passing through the pneumatic airway 1211, and enhancing the top support force of the piston push rod 1226 on the limit pad 122, so as to quickly stop the patient's tipping tendency and avoid the patient from tipping and falling.

[0038] As an embodiment of the present invention, Figure 6 As shown, a through hole connected to the pneumatic airway 1211 is provided inside the convex gear body 1223 along the axis core toward the limiting pad 122, and one end of the through hole is connected to the S-shaped inflation airway 1221 opened inside the limiting pad 122, and the output end of the inflation airway 1221 extends through to the rotating shaft position connected to the torsion spring 1224, one end of the torsion spring 1224 is fixed on the inner wall of the axial hole of the clamping pad groove 124, and the axial hole is connected to the inflation airway 1221, and the axial hole is connected to the L-shaped return airway 1218 opened below the clamping pad groove 124 inside the mattress 12, the output end of the return airway 1218 extends to the position of the air pump 123, and a plurality of telescopic airbags 1222 are integrally sealed and fixed on the upper surface of the limiting pad 122, and the interior of the telescopic airbags 1222 is connected to the inflation airway 1221 through the branch holes opened.

[0039] During operation, after the piston push rod 1226 flips the limit pad 122 out and positions the human body, the gas breaks through the one-way valve and enters the convex gear body 1223 and the inflation airway 1221, and then inflates the telescopic airbag 1222 through the branch hole to adhere to the patient's skin, thereby cooling the patient's upper body, assisting anesthesia and improving the stability of the surgical position. After being filled, the airflow enters the space where the torsion spring 1224 is located, and then is output to the vicinity of the air pump 123 through the return airway 1218.

[0040] In summary, through the arrangement of the mattress 12, the bed frame 121, the liquid cooling box 1217, the pneumatic airway 1211, the limiting pad 122, the convex gear body 1223, the inflatable airway 1221, the telescopic airbag 1222, the torsion spring 1224, the return airway 1218 and the air pump 123, the patient can be assisted in positioning while the introduced gas can be quickly cooled, so that the cold air flow can locally absorb heat and cool the patient's upper body, reduce the patient's body oxygen consumption, metabolism, local vasodilation and blood flow, assist in the anesthesia of the patient, and be more conducive to improving the stability of the operation and reducing the risk of the operation.

[0041] Working principle: When performing a surgery in the lateral position, first perform preoperative preparations according to the corresponding surgical requirements, then arrange the patient to lie in the lateral position on the nursing bed, and after lying down, cooperate with the patient to perform preoperative treatment and some basic limb positioning, then check whether the liquid cooling box 1217 can meet the refrigeration requirements, and replace the liquid inside the liquid cooling box 1217, then connect the power supply of the air pump 123, so that the air pump 123 sucks the surrounding air and pumps the air into the pneumatic airway 1211, and the air entering the pneumatic airway 1211 will first pass through the liquid cooling box 1217, and after being cooled by the liquid cooling box 1217, it will continue to flow along the pneumatic airway 1211, and then the cold air flow will pass through the conical valve stem 1212 and the valve The seat 1214 enters the interior of the connecting air pipe 1228, and is diverted by the connecting air pipe 1228 into the interior of the gas rod 1225. The airflow entering the interior of the gas rod 1225 will push the piston push rod 1226 to extend outward along the gas rod 1225, and push the limiting pad 122 to flip out from the inside of the clamping pad groove 124. At this time, the convex gear body 1223 will idle, and the torsion spring 1224 will be twisted and contracted. As the gas continues to be filled, the limiting pad 122 will push on both sides of the human body to position the human body. Then the gas will break through the restriction of the one-way valve and enter the interior of the convex gear body 1223 along the pneumatic airway 1211, and then enter the interior of the inflation airway 1221 along the convex gear body 1223, and enter the cooling airway 1221. The airflow will enter the interior of the telescopic airbag 1222 through the branch hole, inflate the telescopic airbag 1222, expand the telescopic airbag 1222 and flexibly adhere to the patient's skin surface, locally absorb heat and cool the patient's upper body, reduce the patient's body's oxygen consumption, metabolism, local vascular expansion and blood flow, assist in anesthesia of the patient, and improve the stability of the human body surgical position when the patient is tilted. After the telescopic airbag 1222 is filled, the airflow will continue to flow along the inflation airway 1221 and enter the space where the torsion spring 1224 is located, and then enter the interior of the return airway 1218 from the space where the torsion spring 1224 is located, and finally be output from the return airway 1218 to the vicinity of the air pump 123. At this time, the operation on the patient can be performed. During the operation, if the patient falls to one side, the patient's body will be pressed on the surface of one of the limit pads 122, and the limit pad 122 will be pushed by the telescopic airbag 1222 to rotate downward. During the rotation of the limit pad 122, it will drive the convex gear body 1223 to rotate, and the convex gear body 1223 will push the spring rod 1216 through the cam structure on the side, so that the spring rod 1216 compresses the spring and moves downward, and the downward moving spring rod 1216 will push the driving cone 1215 to move downward, and then the driving cone 1215 will push the conical valve stem 1212 to move in the opposite direction of the valve seat 1214 while stretching the limit spring 1213, and then the open area between the conical valve stem 1212 and the valve seat 1214 will increase,In this way, the amount of air passing through the conical valve stem 1212 and the valve seat 1214 will be greatly increased, and the amount of gas entering the connecting air pipe 1228 and the air rod 1225 from the pneumatic airway 1211 will also increase, and the air pressure inside the air rod 1225 will increase, and then the piston push rod 1226 will have a stronger pushing force on the limit pad 122, thereby enhancing the positioning and supporting capabilities of the human body and preventing the patient from falling.

[0042] It should be noted that the cold liquid in the liquid cooling box 1217 can be liquid nitrogen, ice water, ice cubes and other refrigerants. At the same time, it is necessary to meet the requirements of short-distance and rapid cooling to a predetermined temperature, so that the refrigerated gas can pass through the telescopic airbag 1222 and contact the human body to cool the contact position to a range of 28-32 degrees, so as to achieve the conditions of medium-low temperature anesthesia; initially, there is a specified open area between the conical valve stem 1212 and the valve seat 1214; and a pressure relief valve for relieving pressure to the outside is arranged on the pneumatic airway 1211 between the valve seat 1214 and the air pump 123.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
