Description

Technical Field

[0001] The invention belongs to the technical field of sputum suction devices, and in particular relates to a vibration sputum removal rehabilitation device. Background Art

[0002] Coughing and expectoration is a common and important defensive mechanism. Some critically ill patients are unable to expectorate on their own, which makes it impossible to cough up sputum on their own and easily accumulates in the respiratory tract. If too much sputum accumulates, it will block the airway, affect respiratory function, and increase the risk of lung infection. Therefore, a sputum suction device is needed to suction the sputum of the patient. For example, a sputum suction device for critically ill neurosurgery patients is proposed in patent announcement number CN109364342A.

[0003] When medical staff are suctioning patients, they often require the patients to lie on their side in bed and pat the patients' backs with their hands. By using the vibration and gravity, the sputum is prompted to converge from the bronchi and bronchioles toward the main bronchi so that it can be sucked out later with a suction device. However, during the suction process, because the suction tube is inserted into the patient's trachea, its suction port is in the blind spot of the medical staff's field of vision and cannot be directly observed. As a result, when patting the patient's back, it is very easy for the suction port of the suction tube to be out of sync with the patting part. For example, the medical staff focuses on patting a specific area of ​​the patient's back to loosen and push the sputum to shift, but the suction port of the suction tube is located in other parts of the trachea, making it difficult for the sputum to flow effectively toward the suction port. Instead, it is dispersed in the trachea and cannot be sucked out smoothly. After all, patting the back is intended to guide the sputum to a place where it is easier to suck out. If the suction tube is improperly positioned, it will be difficult to effectively gather the sputum, which will ultimately lead to a decrease in the patient's sputum output and adversely affect their respiratory function.

[0004] Therefore, a vibration expectoration rehabilitation device is proposed to solve the above problems. Summary of the Invention

The same spring arranged on the outside of the transverse rod 44 is fixedly connected between the circular plate 45 and the positioning frame 40. When the medical staff holds the sputum suction tube 8 and inserts it into the patient's body, the length of the sputum suction tube 8 can be marked in advance, thereby avoiding the problem of the sputum suction tube 8 being inserted too deeply into the patient's trachea, which may cause damage to the bronchi and lungs, and further improving the safety of the sputum suction device.

[0036] Two guide rollers 46 are fixedly connected to the left side wall of the adjustment cylinder 221 , and the left end of the pull rope 25 passes through the two guide rollers 46 , thereby improving the smoothness of the movement of the pull rope 25 .

[0037] A guide rod 47 is fixedly connected between the mounting plate 15 and the vibration frame 142 , and a guide cylinder 48 matching the guide rod 47 is fixedly connected to the side wall of the movable plate 17 , thereby improving the stability of the movable plate 17 in moving left and right.

[0038] A switch 49 is fixedly connected to the upper side wall of the support frame 111 , and the left ends of the two resistor plates 24 are electrically connected to the electromagnetic block 27 through the switch 49 , respectively, which can control the electrical connection between the electromagnetic block 27 and the corresponding resistor plate 24 .

[0039] The operating principle of the present invention is described as follows: the medical staff moves the sputum removal device to the vicinity of the patient's bed, and then assists the patient to lie on the bed in a side-lying position. The medical staff then removes the support frame 111 from the upper side of the placement plate 10 and covers it above the patient's body, and then adjusts the placement position of the support frame 111 (refer to Figure 4, so that the support cover 13 on the right side is aligned with the patient's back), then the medical staff sends an electrical signal to the PLC controller 9 through the external remote control, and the PLC controller 9 will control the support electric push rods 12 on both sides to work (the PLC controller 9 is electrically connected to the support electric push rods 12 through wires), and the support electric push rods 12 simultaneously drive the support electric push rods 12 on both sides to work, so that the support electric push rods 12 drive the support cover 13 to move in the direction close to the patient. When the support cover 13 contacts the patient, an interaction force is generated. After the pressure sensor between the support electric push rods 12 and the support cover 13 detects that the interaction force reaches a set threshold, the pressure sensor will send an electrical signal to the PLC controller 9. After receiving the electrical signal, the PLC controller 9 will immediately control the support electric push rods 12 on both sides to stop moving, so that the support covers 13 on both sides can be used to support the patient's body, so that the patient can maintain a lateral position on the bed with more effort, thereby improving the patient's comfort during sputum suction;

[0040] Then, the medical staff adjusts the length of the suction tube 8 inserted into the patient's body based on experience and the patient's specific height, body shape and other factors (usually, when an adult is inserted through the mouth, the insertion depth of the suction tube 8 is generally about 14-16 cm), and then slides the connecting sleeve 341 to the corresponding position of the suction tube 8, and then pulls the bent plate 39 upward. The bent plate 39 will drive the pull rod 37 and the piston block 38 to move upward, and the piston block 38 will extract the gas inside the annular cavity 342, and the suction tube 8 and the connecting sleeve 341 will contact each other. After the gas inside the annular cavity 342 is extracted, The annular cavity 342 will be kept in a negative pressure state, so that the suction tube 8 is adsorbed by the suction hole 35, so that the suction tube 8 and the connecting sleeve 341 are kept relatively fixed, and the bent plate 39 will be fixed in position by the mutual cooperation of the first latch 42 and the second latch 43 during the upward movement. When the medical staff releases their hands, the piston block 38 will not retract into the air pressure cylinder 36. Subsequently, the circular plate 45 can be pulled to drive the first latch 42 and the second latch 43 to separate through the cross bar 44 and the positioning plate 41, thereby fixing the bent plate 39.

[0041] Then the medical staff pulls the pull rope 25 near the patient's head, and connects the left end of the pull rope 25 to the connecting sleeve 341 through the hook mechanism. Then the medical staff presses the switch 49 to electrically connect the resistor plate 24 and the electromagnetic block 27 near the patient's head, and then transmits an electric signal to the PLC controller 9 through the external remote controller. After receiving the electric signal, the PLC controller 9 will control the conductive frame 23 to be energized and control the negative pressure pump 2 to work. Then the medical staff inserts the end of the suction tube 8 into the patient's trachea through the patient's mouth, and uses the suction tube 8 to extract the sputum inside the patient's trachea and transport it to the collection tube 4 for storage. When the medical staff inserts the suction tube 8 into a deeper position in the trachea, the sliding block 222 is pulled by the spring on the right side. It will drive the conductive frame 23 to move to the right, so that the conductive frame 23 contacts the left end of the resistor plate 24, the conductive frame 23 is electrically connected to the external power supply, and the left end of the resistor plate 24 is electrically connected to the electromagnetic block 27. When the conductive frame 23 contacts the left end of the resistor plate 24, the external current will be transmitted to the electromagnetic block 27. Since the resistance connected to the circuit of the electromagnetic block 27 is small at this time, when the external voltage remains unchanged, the current transmitted to the circuit of the electromagnetic block 27 is large, thereby increasing the magnetic attraction generated by the electromagnetic block 27. The electromagnetic block 27 will attract the permanent magnet block 29 to move to the rear, and the electromagnetic block 27 will drive the two trigger switches 32 to move backward together through the sliding block 28 and the U-shaped frame 31. The trigger switch 32 on the front side will contact the trigger switch 32 during the backward movement. When the rod 33 contacts, the trigger rod 33 will squeeze the trigger switch 32 on the front side, and the trigger switch 32 on the front side is electrically connected to the reverse circuit of the linear motor 141. The linear motor 141 will drive the vibration frame 142 to move backward to the rearmost position, so that the vibration cover 18 and the patient's back are aligned near the upper position. When the PLC controller 9 detects that the linear motor 141 has been working for two seconds, it will control the drive motor 19 to work. The drive motor 19 will drive the turntable 20 and the lifting rod 21 to rotate together. During the rotation, the lifting rod 21 will push the moving plate 17, the vibration rod 16 and the vibration cover 18 to the right by a certain distance. When the lifting rod 21 is separated from the moving plate 17, under the action of the spring tension, the moving plate 17 will move together through the vibration rod 16 and the vibration cover 18 Move quickly to the left, and use the vibration cover 18 to pat the higher part of the patient's back, and use the vibration to loosen the sputum inside the patient's trachea and cause displacement (at this time, the patient is lying on the right side of the bed, and the sputum inside the left bronchus will also move to the main trachea due to vibration, which is convenient for the suction tube 8 to absorb. After the patient has been suctioning on the right side for 4 minutes, he needs to lie on the left side of the bed to clean the sputum inside the right bronchus). The vibration cover 18 is a hollow structure, which can simulate the hollow palm of the hand, reducing the force of the patting. The diameter of the vibration cover 18 is ten centimeters, so that the suction port of the suction tube 8 is within the vibration range of the vibration cover 18, which enables the sputum to move toward the suction port, effectively improving the suction effect of the sputum suction device.When the medical staff gradually inserts the suction tube 8 into the patient's trachea, the sliding block 222 will drive the conductive frame 23 to gradually move to the right, thereby gradually increasing the resistance on the circuit connected to the electromagnetic block 27. When the external voltage remains unchanged, the current supplied to the circuit of the electromagnetic block 27 gradually decreases, thereby gradually reducing the magnetic attraction generated by the electromagnetic block 27. The sliding block 28 gradually moves forward under the tension of the spring. The sliding block 28 drives the U-shaped frame 31 forward through the guide plate 30, so that the trigger switch 32 on the rear side is squeezed and triggered by the trigger rod 33. The trigger switch 32 on the rear side is electrically connected to the positive circuit of the linear motor 141. When the trigger switch 32 on the rear side is triggered, the linear motor 141 will drive the vibration cover 18 to gradually move forward, thereby causing the vibration cover 18 to move synchronously with the suction port of the suction tube 8, sucking out sputum deeper in the patient's trachea, and ensuring the sufficient cleaning of the patient's sputum.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
