Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a pneumothorax nursing device. Background Art

[0002] Tension pneumothorax refers to the rupture of larger alveoli or larger and deeper lung lacerations or bronchial ruptures. The lacerations are connected to the pleural cavity and form a one-way valve, also known as high-pressure pneumothorax. During inhalation, air enters the pleural cavity through the lacerations, while during exhalation the valve closes and the air in the cavity cannot be discharged, causing the pressure in the pleural cavity to continue to rise, compressing the lungs and causing them to gradually collapse, resulting in serious obstruction of respiratory and circulatory functions. Therefore, a nursing device is needed to extract the gas in the chest cavity, reduce the pressure in the chest cavity, allow the lung tissue to expand again, and restore normal respiratory function. It plays a key role in the treatment of pneumothorax patients in clinical medicine, relieves pain for patients, and promotes recovery. For example, a pneumothorax emergency device for cardiothoracic surgery nursing is proposed in patent announcement number CN217828495U.

[0003] When the existing pneumothorax nursing device is in use, blood, pus, fibrin and other substances in the drainage fluid may coagulate in the drainage tube, causing blockage, obstructing the discharge of gas and fluid in the chest cavity, and gas will accumulate in the chest cavity, thereby aggravating the symptoms of pneumothorax. Therefore, when using the nursing device, medical staff are required to squeeze the drainage tube regularly (1-2 hours), and need to squeeze from the proximal end to the distal end to keep the lumen unobstructed and prevent blood, secretions and other coagulation and blockage. In the medical environment, especially in some departments with a large number of patients and serious conditions, such as intensive care units, medical staff often need to take care of multiple patients at the same time. Each patient may have a variety of treatment and nursing tasks to complete, including regular squeezing of the drainage tube, observing vital signs, administering medicine, assisting patients to turn over, etc. When the drainage tube needs to be squeezed every 1-2 hours, this will increase the nursing workload of medical staff, which may make it difficult for them to ensure that the squeezing operation of the drainage tube of each patient is completed strictly at the prescribed time interval during their busy schedule, thereby affecting the drainage effect.

When the drainage tube 5 is frequently blocked, the medical staff or accompanying personnel can be promptly reminded to check whether the drainage tube 5 is compressed or bent.

[0038] A micro electric push rod 47 is fixedly connected to the inner wall of the mounting frame 16 , and a movable end of the micro electric push rod 47 is fixedly connected to a limiting block 48 . A limiting groove 49 matching the limiting block 48 is formed on the inner wall of the storage cavity 11 , so as to fix the blocking block 92 .

[0039] The lower ends of the two support frames 20 are fixedly connected with support arc plates 50 . The two support arc plates 50 are respectively located on the left and right sides of the metal needle tube 91 , thereby improving the support capacity of the metal needle tube 91 .

[0040] The operating principle of the present invention is now described as follows: the center of the compression plate 1 is placed at the second intercostal space on the midclavicular line of the pneumothorax patient, and then the doctor inserts the metal needle tube 91 into the patient's chest cavity for drainage. After the metal needle tube 91 is punctured, the doctor moves the separated mounting tube 7 to the bottom of the curved tube 8 and merges them together, and then fixes them with bolts and other fixings. The curved tube 8 will pass through the merged mounting tube 7. Then the doctor rotates the mounting tube 7 and fixes the mounting tube 7 to the surface of the compression plate 1 through the threaded fit between the threaded ring 6 and the mounting tube 7. Then the doctor pulls the pull plates 29 on both sides, and the pull plates 29 drive the clamping plates 26 upward through the clamping rods 25. The upper latching teeth 27 on the lower side of the clamping plate 26 and the lower latching teeth 28 on the upper side of the positioning pin 182 are separated. Under the tension of the spring, the vertical plate 19 drives the positioning pin 182 and the support frame 20 to move toward the direction close to the metal needle tube 91 and the drainage tube 5, so that the two supporting arc plates 50 and the left and right sides of the metal needle tube 91 are fitted, and the two detection arc plates 21 are fitted with the left and right sides of the drainage tube 5, so as to fix the placement angle of the metal needle tube 91, and avoid the problem of pain and discomfort caused by the displacement or angle change of the puncture needle during the patient's turning over and coughing. Then the doctor connects the delivery tube 302 with the upper end of the curved tube 8.

[0041] The gas and effusion in the chest cavity of a pneumothorax patient can be drained through the metal needle tube 91 and the drainage tube 5. During the drainage process, the lamp bead 22 on the surface of the left detection arc plate 21 will continue to work. The effusion in the patient's chest cavity is light yellow. As the drainage time increases, some components in the drainage fluid, such as protein, fibrinogen, etc., may undergo aggregation, precipitation, and other changes. In particular, when these components reach a certain concentration, begin to interact with each other and coagulate, the drainage fluid will become thick and the color will darken, presenting a dark yellow and turbid state. The drainage tube 5 is illuminated by the lamp bead 22, and then the color of the drainage fluid in the drainage tube 5 is detected by the color recognition sensor 23. When the detection finds that the color in the drainage tube 5 becomes dark When the color turns yellow, the color recognition sensor 23 will send an electrical signal to the PLC controller 4. After receiving the electrical signal, the PLC controller 4 will first control the liquid supply valve 40 to open for one second, and control the small electric push rod 34 to work. The small electric push rod 34 will squeeze the piston seat 32 to move through the spring between the induction plate 35 and the induction tube 33, and use the piston seat 32 to squeeze the saline solution inside the water tank 301, so that a part of the saline solution is transported to the prompt box 38 through the liquid supply pipe 39, so that the piston plate 41 in the prompt box 38 moves forward, and the piston plate 41 stops at a position two centimeters away from the control switch 43, so as to facilitate the subsequent detection of the bending condition of the drainage tube 5 (the specific detection steps are described in detail later). When the supply After the liquid valve 40 is opened for one second and closed at the same time, the PLC controller 4 will control the magnetic control valve 31 to open, so that the physiological saline is delivered to the storage chamber 11 through the delivery tube 302, the elbow 8 and the liquid inlet chamber 17, so that the water pressure below the piston ring 14 increases, and the water pressure will push the piston ring 14 and the blocking block 92 to move upward together, so that the blocking block 92 blocks the drainage port 10. When the piston ring 14 drives the blocking block 92 to move upward to the set position, the trigger switch 15 will contact the inside of the storage chamber 11 and be squeezed and triggered. The trigger switch 15 will control the micro-electric push rods 47 on the left and right sides to work through the PLC controller 4, so that the micro-electric push rods 47 drive the limit block 48 to insert into the limit groove 49, so that the position of the block block 92 can be adjusted. The PLC controller 4 will then control the control valve 13 to open, so that the physiological saline is delivered to the metal needle tube 91 through the injection hole, and the drainage fluid that has solidified and blocked the metal needle tube 91 and the drainage tube 5 is flushed from the proximal end to the distal end with the physiological saline, so that the solidified part of the drainage fluid is flushed clean. After the flushing work is performed for ten seconds, the PLC controller 4 will control the small electric push rod 34 to drive the piston seat 32 to move back one centimeter, and at the same time control the control valve 13 to close, and control the micro electric push rod 47 to drive the limit block 48 and the limit groove 49 to separate. When the piston seat 32 moves back in the water tank 301, part of the physiological saline in the storage chamber 11 will flow back into the water tank 301, so that the area below the piston ring 14 is in a negative pressure state.Thereby controlling the piston ring 14 to drive the blocking block 92 to move downward to the initial position and continue the drainage work;

[0042] When the small electric push rod 34 pushes the induction plate 35 to move, the induction plate 35 will squeeze the induction tube 33 and the piston seat 32 through the spring. During the movement of the induction plate 35, the conductive frame 36 and the conductive plate 37 will be brought into contact. The conductive frame 36 is electrically connected to the external power supply, and the conductive plate 37 is electrically connected to the PLC controller 4. When the conductive frame 36 and the conductive plate 37 are in contact, an electrical signal will be transmitted to the PLC controller 4, and the PLC controller 4 will control the small electric push rod 34 to stop working, and apply pressure to the piston seat 32 through the spring, so that the piston seat 32 squeezes the physiological saline behind. The physiological saline is under pressure. Under the action of the piston seat 32, the physiological saline will be transported into the drainage tube 5, thereby reducing the physiological saline behind the piston seat 32. The piston seat 32 will move backward under the action of the spring force in front. When the piston seat 32 moves backward due to the reduction of the physiological saline at the rear, the piston seat 32 will drive the sensing cylinder 33 and the conductive plate 37 to move backward together, thereby separating the conductive plate 37 and the conductive frame 36, thereby disconnecting the electrical signal transmitted to the PLC controller 4. When the PLC controller 4 detects this situation, it will control the small electric push rod 34 to continue moving, thereby applying a certain pressure to the piston seat 32, so that the physiological saline is evenly transported into the drainage tube 5;

[0043] When saline is delivered to the prompt box 38, referring to the above principle, the piston plate 41 will squeeze the spring in front, so that the spring applies elastic force to the piston plate 41, and the piston plate 41 will squeeze the saline under the action of the spring elastic force, and the saline will be delivered to the transparent storage bag 45 through the return water capillary 44. Twenty minutes after the first flushing work starts, the remaining saline in the prompt box 38 will be completely discharged into the transparent storage bag 45. Within twenty minutes after the first flushing work starts, when the drainage tube 5 is blocked again, referring to the above principle, saline will enter the prompt box 38 again. At this time, there will be residual saline in the prompt box 38, and the excess saline will push the piston plate 41 to squeeze the control switch 43. The control switch 43 will be closed through the liquid supply valve 40 of the PLC controller 4, and the buzzer 46 will be controlled to work, so as to promptly remind the medical staff or accompanying personnel to check whether the drainage tube 5 is compressed or bent.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
