Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, in particular to a postoperative expectoration nursing auxiliary machine. Background Art

[0002] After surgery, patients have weaker constitutions and decreased immunity, making them susceptible to colds and other illnesses. When a cold occurs, the patient's lungs will secrete more sputum, and the patient's nasal cavity will also secrete more mucus, usually called nasal discharge. Postoperative patients need the help of an auxiliary machine to expectorate, usually through suction equipment.

[0003] When using existing sputum suction equipment, it is necessary to insert a cannula into the patient's throat or nasal cavity, and then start the negative pressure pump of the sputum suction equipment to generate suction in the cannula. The cannula located in the patient's throat or nasal cavity sucks out the sputum. In this process, when the sputum is relatively viscous, the sputum is easy to adhere to the inner wall of the cannula and gradually accumulate to block the cannula. In order to avoid patient discomfort, medical staff will not increase the suction force to extract the sputum blocked inside the cannula. Specifically, excessive suction force can easily cause the end of the cannula to adsorb the mucosa in the throat or nasal cavity, causing patient discomfort. Therefore, when medical staff find that the cannula is blocked, they need to stop expectorating the patient, and continue expectoration after cleaning and unblocking the cannula. The efficiency of expectoration is low.

[0004] To this end, the present invention provides a postoperative expectoration nursing auxiliary machine. Summary of the Invention

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figures 1 to 11 As shown, a postoperative sputum removal nursing auxiliary device according to an embodiment of the present invention includes a shell 1, a pump body 11 is fixedly connected to the interior of the shell 1, the output end of the pump body 11 is connected and fixedly connected to a discharge pipe 12, the discharge pipe 12 passes through the outside of the shell 1, the input end of the pump body 11 is connected and provided with a swivel 2, the swivel 2 is rotatably connected to the input end of the pump body 11, the end of the swivel 2 away from the pump body 11 is connected and provided with a suction pipe 13, the end of the suction pipe 13 is slidably connected to the side of the swivel 2, and the end of the suction pipe 13 passes through the outside of the shell 1; A gear ring 21 is sleeved and fixed on the outer side of the swivel 2, and a gear 22 is meshed and connected to the side of the gear ring 21. A motor 23 is fixed to the inside of the housing 1, and the output end of the motor 23 is fixed to the center of the side of the gear 22. A receiving frame 24 is fixed to the inside of the swivel 2, and a pair of rubber scrapers 25 are fixed to the surface of the receiving frame 24. A plurality of rubber push rods 26 are fixed between the pair of rubber scrapers 25. The rubber scrapers 25 are inserted into the interior of the suction tube 13 and contact the inner wall of the suction tube 13; When using the sputum suction device, when the sputum is relatively viscous, the sputum is easy to adhere to the inner wall of the cannula, and gradually accumulates to block the cannula. In order to avoid discomfort to the patient, the medical staff will not increase the suction force to extract the sputum blocked inside the cannula. Specifically, it is because the suction force is too large that the end of the cannula can easily adsorb the mucosa in the throat or nasal cavity, causing discomfort to the patient. Therefore, when the medical staff finds that the cannula is blocked, they need to stop expectorating the patient and continue expectoration after cleaning and unblocking the cannula. The efficiency of expectoration is low. To solve the above problems, the embodiment of the present invention is provided with multiple structures such as rubber scrapers 25 and rubber push rods 26. The specific use process is as follows: when in use, the suction tube 13 is first inserted into the patient's throat or nasal cavity, and then the pump body 11 is started. The pump body 11 generates suction so that the suction tube 13 draws out the sputum inside the throat or nasal cavity, and at the same time the motor 23 is started, and the motor 23 drives the gear 22 The gear 22 drives the gear ring 21 to rotate, the gear ring 21 drives the swivel 2 to rotate, the swivel 2 drives the internal receiving frame 24 to rotate, the receiving frame 24 drives the rubber scraper 24 to rotate, and a pair of rubber scrapers 25 are supported by multiple rubber top rods 26, so that when the pair of rubber scrapers 25 rotate, the rubber scrapers 25 continue to adhere to the inner wall of the suction tube 13. As the receiving frame 24 rotates, the pair of rubber scrapers 25 continue to adhere to the inner wall of the suction tube 13 and rotate, scraping the sputum attached to the inner wall of the suction tube 13, driving the sputum to flow through the discharge tube 12 for discharge. In this process, the suction tube 13 located outside the shell 1 can be deformed and bent, and the internal rubber scraper 25 bends synchronously without interference. During the entire sputum discharge process, the suction tube 13 is prevented from being blocked, which is beneficial to reducing the probability of medical staff stopping sputum discharge due to clearing blockage, thereby improving the efficiency of sputum discharge.

[0023] The top of the shell 1 is fixedly connected with a water pump 5, the output end of the water pump 5 is connected and fixedly connected with a water injection pipe 51, the bottom end of the water injection pipe 51 is connected and fixedly connected with an annular water tank 52, the annular water tank 52 is fixedly connected to the side of the shell 1 and the suction pipe 13 passes through the annular water tank 52, the side of the annular water tank 52 is connected and fixedly connected with a plurality of water adding pipes 53, the end of the water adding pipe 53 away from the annular water tank 52 is located at the end of the suction pipe 13 and passes through the suction pipe 13; when in use, the water pump 5 is started, the input end of the water pump 5 is connected to the cleaning liquid, the water pump 5 draws the cleaning liquid from the outside, injects it into the annular water tank 52 through the water injection pipe 51, and then passes through the water adding pipe 53 is discharged to the end of the suction tube 13, and the cleaning liquid is sprayed out at the end position of the suction tube 13, and moves with the sputum. The cleaning liquid contacts the rubber scraper 25, the rubber top rod 26 and the inner wall of the suction tube 13, preventing the sputum from accumulating on the rubber scraper 25, the rubber top rod 26 and the inner wall of the suction tube 13, which is beneficial to improving the smoothness of the flow of sputum when it is extracted; it should be pointed out that the cleaning liquid is discharged to the end position of the suction tube 13 through the water supply pipe 53, and the cleaning liquid entering the inside of the suction tube 13 will be guided by the suction force of the suction tube 13 to avoid splashing outside the suction tube 13 and causing irritation to the patient's throat or nasal cavity.

[0024] The outer side of the suction tube 13 is sleeved with a restraining sleeve 54, which squeezes and restrains the water adding tube 53 surrounding the suction tube 13 to the surface of the suction tube 13; this prevents the water adding tube 53 from causing discomfort to the patient when the suction tube 13 is inserted into the patient's throat and nasal cavity, that is, the water adding tube 53 causes the patient to feel a raised support. By providing the restraining sleeve 54, the surface of the suction tube 13 can be kept smooth when inserted into the patient's throat and nasal cavity.

[0025] like Figures 10 to 12 As shown, a connecting rod 27 is fixedly connected to the side of the rubber top rod 26, and an end of the connecting rod 27 close to the end of the suction tube 13 is fixedly connected to an endoscope lens 28. The endoscope lens 28 is used to shoot the picture in front of the suction tube 13 and transmit the picture information to an external computer through an electrical signal; when in use, the endoscope lens 28 transmits the picture inside the patient's throat or nasal cavity to the external computer, and the medical staff can continuously adjust the position of the suction tube 13 according to the picture displayed on the computer, which is conducive to quickly finding and extracting sputum; further, the direction in which the cleaning liquid is sprayed out of the water adding pipe 53 points to the endoscope lens 28, and the cleaning liquid sprayed out of the water adding pipe 53 will rinse the endoscope lens 28 to prevent the endoscope lens 28 from being wrapped by sputum and affecting its use.

[0026] like Figures 8 and 9As shown, the portion of the suction tube 13 located inside the housing 1 is connected and fixedly connected to the detection cylinder 3, and the detection gas plate 31 is slidably connected to the interior of the detection cylinder 3. The end of the detection cylinder 3 away from the suction tube 13 is fixedly connected to a bracket 32, and a pressure spring is fixedly connected between the bracket 32 ​​and the detection gas plate 31. A U-shaped frame 33 is fixedly connected to the side of the detection gas plate 31 facing the outside of the detection cylinder 3, and the end of the U-shaped frame 33 away from the detection gas plate 31 is located on the outside of the detection cylinder 3. An early warning device 4 is provided inside the shell 1, and a support rod is fixedly connected between the early warning device 4 and the inner wall of the shell 1. When the detection gas plate 31 moves in the direction close to the suction tube 13, it will drive the end of the U-shaped frame 33 to move toward the position close to the switch button of the early warning device 4; in the process of extracting sputum through the suction tube 13, when the end of the suction tube 13 is adsorbed on the mucous membrane of the throat or nasal cavity, the negative pressure of the gas inside the suction tube 13 will increase instantly, and the negative pressure inside the detection cylinder 3 connected to the suction tube 13 will increase synchronously. Under the action of negative pressure, the detection gas plate 31 moves in the direction of the suction tube 13, driving the U-shaped frame 33 to move synchronously. When the U-shaped frame 33 moves, the end outside the detection cylinder 3 squeezes the switch button of the early warning device 4. When the early warning device 4 is squeezed, an early warning is issued to the medical staff, and the medical staff is promptly reminded to turn off the pump body 11 to prevent the end of the suction tube 13 from continuously adsorbing the mucous membrane and causing discomfort to the patient.

[0027] like Figures 4 and 5 As shown, the suction tube 13 includes an inner tube 131 and an outer tube 132. The inner tube 131 is located inside the outer shell 1 and is connected to the swivel 2. A plurality of docking grooves 1311 are provided at the end of the inner tube 131 away from the swivel 2. The outer tube 132 is located outside the outer shell 1 and a plurality of docking rods 1321 are fixedly connected to the end of the outer tube 132 close to the inner tube 131. The ends of the docking rods 1321 away from the outer tube 132 are inserted into the docking grooves 1311, and there is friction between the surface of the docking rods 1321 and the inner wall of the docking grooves 1311. When cleaning the suction tube 13, the inner tube 131 and the outer tube 132 can be separated for easy cleaning. When in use, the docking rods 1321 are inserted into the docking grooves 1311 and fixed by the friction between the surface of the docking rods 1321 and the inner wall of the docking grooves 1311.

[0028] like Figures 8 to 14 As shown, the side of the input end of the pump body 11 is connected and fixedly connected with a one-way valve 8. The medium of the one-way valve 8 flows from the outside to the inside of the input end of the pump body 11. The input end of the one-way valve 8 is slidably connected with a blocking plate 7. Initially, the blocking plate 7 blocks the input end of the one-way valve 8. The top end of the blocking plate 7 is fixedly connected to a pull rod 71. The top end of the pull rod 71 is fixedly connected to a top plate 72. The top end of the top plate 72 is fixedly connected to a return spring 73. An inflatable cylinder 6 is provided above the blocking plate 7. A top plate 72 is slidably connected to the inner wall of the inflatable cylinder 6. The top end of the return spring 73 is fixedly connected to the top end of the inflatable cylinder 6. The top end of the inflatable cylinder 6 is connected to and fixed with an inflatable hose 61. The top end of the inflatable hose 61 is fixedly connected to an inflatable ball 62. During use, the patient holds the inflatable ball 62 in his hand. When the end of the suction tube 13 is adsorbed onto the patient's mucosa, the patient squeezes the inflatable ball 62. The gas inside the inflatable ball 62 enters the inflatable cylinder 6 through the inflatable hose 61, causing the top plate 72 inside the inflatable cylinder 6 to move downward by the gas, thereby driving the blocking plate 7 at the bottom end of the pull rod 71 to move downward. When the blocking plate 7 moves downward, the input end of the one-way valve 8 is opened. At this time, there is a negative pressure inside the suction tube 13 because the end is blocked. Therefore, the outside air quickly passes through the one-way valve 8. Enter the interior of the suction tube 13, offset the negative pressure inside the suction tube 13, and then release the adsorption of the end of the suction tube 13 on the mucosa. Through the patient's self-feeling, the adsorption of the end of the suction tube 13 on the mucosa can be instantly released, which is convenient for the patient to maintain comfort during the sputum discharge process; then stop squeezing the inflation ball 62, and under the action of the elastic force of the reset spring 73, the top plate 72 drives the sealing plate 7 at the bottom end of the pull rod 71 to reset; it should be pointed out that the inflation cylinder 6 is fixed to the inside of the shell 1 by a mounting part (not shown in the drawings of the specification).

[0029] A reel 9 is fixedly connected to the top of the shell 1, and the reel 9 is used to reel in the inflation hose 61; to prevent the excess inflation hose 61 from scattering, a plurality of isolation sheets 91 are fixedly connected to the annular surface of the reel 9, and the surface of the isolation sheets 91 is provided with arc-shaped protrusions, and the upper and lower spacings between the isolation sheets 91 are the same as the diameter of the inflation hose 61; when reeling, the inflation hose 61 can be embedded between the isolation sheets 91. Since the upper and lower spacings between the isolation sheets 91 are the same as the diameter of the inflation hose 61, and the surface of the isolation sheets 91 is provided with arc-shaped protrusions, the inflation hose 61 will be embedded between the isolation sheets 91 and restricted by the protrusions, further preventing the reeled inflation hose 61 from dispersing, and avoiding interference with the sputum discharge operation of medical staff.
