Description

Technical Field

[0001] The invention belongs to the technical field of anesthesia devices, in particular to an anesthesia device with adjustable concentration for anesthesia department. Background Art

[0002] There are many diseases that require surgical treatment, such as various uncontrollable hemorrhagic diseases, tumors, acute abdomen, and serious life-threatening diseases. In order to avoid causing pain to patients while maintaining stable vital signs, patients are usually anesthetized so that surgeons can perform surgical operations in a safe environment. Common methods of anesthesia include general anesthesia, nerve trunk and plexus block anesthesia, local anesthesia, and spinal anesthesia. General anesthesia is currently the most widely used, and general anesthesia is generally divided into inhalation general anesthesia, intravenous general anesthesia, and intravenous inhalation combined general anesthesia. Intravenous general anesthesia and intravenous inhalation combined general anesthesia often require the configuration of anesthetic drug concentrations, but if the anesthetic solution is manually configured, there may be a certain error in the concentration. If the concentration of the anesthetic is too high, it will cause discomfort to the human body, may be toxic to the nerves, and have an adverse effect on human health. When the concentration is too low, it is easy for the patient to wake up early or the analgesia is insufficient, which increases the patient's pain and affects the operation. In the existing anesthesia care device, after the delivery tube delivers the anesthetic and diluted liquid, the delivery tube is easy to leave residual liquid, which will cause contamination in the next mixed liquid and cause physical harm to the patient. It is inconvenient to clean the delivery tube and is less practical.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0033] like Figure 1 , Figure 2 , Figure 3 , Fig.10 As shown, the present invention provides an anesthesia device with adjustable concentration for anesthesiology, including a base 1, a stirring tank 11 is fixedly connected to the upper surface of the base 1, and the two sides of the lower part of the stirring tank 11 are connected to the delivery pipes 12, and the upper surfaces of one ends of the two delivery pipes 12 are connected to the support pipes 13, and the two support pipes 13 are connected to the anesthesia tank 14 and the dilution tank 15 through the first connecting plate 132, the second connecting plate 142, and the bolts 16; a lifting mechanism 2 is arranged inside the delivery pipe 12; a pressure mechanism 3 is arranged on the upper part of the support pipe 13; a stirring mechanism 4 is arranged inside the stirring tank 11, and a placement groove 111 is opened at the bottom of the stirring tank 11.

[0034] like Figure 4 , Figure 5 As shown, the lifting mechanism 2 includes a motor 21 fixedly placed at the bottom of the placement groove 111, the output end of the motor 21 is connected to a rotating shaft 22, the upper end of the rotating shaft 22 is sleeved with a cam 23, the two sides of the cam 23 are in contact with a transmission member 24, and a sliding rod 241 is fixedly connected to the middle of one side of the transmission member 24, wherein the outer side of the transmission member 24 is slidably matched with the inside of the conveying pipe 12, and an end face of the sliding rod 241 is fixedly connected to a tilting block 242, and a guide plate 25 is inserted into the outer side of the sliding rod 241. A first spring body 26 is connected between one side of the guide plate 25 and one side of the transmission member 24, and the inclined surface of the inclined block 242 abuts against a transmission rod 27. The upper end of the transmission rod 27 is inserted through a limiting plate 131, and a first pressing plate 271 is fixedly connected to the upper end surface of the transmission rod 27. A second spring body 272 is connected between the lower end surface of the first pressing plate 271 and the upper end surface of the limiting plate 131, and a contact column 273 is fixedly connected to the upper end surface of the first pressing plate 271. The first pressing plate 271 is slidably fitted in the interior of the support tube 13.

[0035] The above scheme is adopted: the starting motor 21 drives the rotating shaft 22 to rotate in a circle, which drives the cam 23 to rotate. The annular surfaces on both sides of the cam 23 are in contact with the semicircular surface of the transmission member 24. The transmission member 24 is subjected to the resistance force of the outer side of the cam 23, so that the transmission member 24 slides inside the conveying pipe 12, wherein the transmission member 24 drives the sliding rod 241 and the tilting block 242 during the sliding process, and one end of the sliding rod 241 slides in the through hole of the guide plate 25. At the same time, the transmission member 24 is pressed to one side by the first spring body 26. Through the arrangement of the guide plate 25 and the first spring body 26, the sliding rod 241 and the transmission member 24 are prevented from shaking when moving to one side, ensuring that the moving force of the sliding rod 241 and the tilting block 242 is fully transmitted to the transmission rod 27. At the lower end, the cam 23 continues to rotate, and the high point of the outer ring surface of the cam 23 gradually slides on the semicircular surface of the transmission member 24, and the sliding rod 241 and the tilting block 242 continue to move to one side, and the lower end of the transmission rod 27 gradually moves upward through the inclined surface of the tilting block 242. In the upward process, the upper end of the transmission rod 27 slides in the inner hole of the limit plate 131. At the same time, it is stretched upward on the second spring body 272 through the first pressure plate 271. The upward force of the transmission rod 27 is resisted by the resistance column 273, so that the second pressure plate 31 is forced to slide upward inside the support tube 13. In order to avoid the deviation of the transmission rod 27 during the upward movement, the design of the limit plate 131 and the second spring body 272 is used to ensure that the deviation is avoided in the vertical upward process.

[0036] like Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, the pressure mechanism 3 includes a second pressure plate 31 that abuts against the upper end surface of the abutting column 273, a sliding rod 32 is connected in the middle of the upper end surface of the second pressure plate 31, the outer side surface of the sliding rod 32 slides in a sliding hole 331 opened at the lower end of the pressure rod 33, a third spring body 332 is connected between the top surface of the sliding hole 331 and the upper end surface of the sliding rod 32, a blocking plate 34 is fixedly connected to the upper end of the pressure rod 33, guide rods 35 are evenly connected to the upper end surface of the blocking plate 34 at equal angles, the lower ends of the guide rods 35 are inserted into sliding holes 361 opened on the periphery of the fixed plate 36, and the upper end surfaces of multiple guide rods 35 are fixedly connected with annular plates 37, and a fourth spring body 38 is connected between the lower end surface of the annular plate 37 and the upper end surface of the fixed plate 36, and the fourth spring body 38 is wound around the outside of multiple guide rods 35.

[0037] The above scheme is adopted: when the second pressure plate 31 is forced to slide upward, the elasticity of the elastic force of the third spring body 332 is greater than the elasticity of the elastic force of the fourth spring body 38, and then, the second pressure plate 31 drives the bearing rod 312, the third pressure plate 313, the sliding rod 32, the pressure rod 33, the blocking plate 34, the buckling plate 333, the guide rod 35, and the annular plate 37 to move upward. At the same time, the annular plate 37 is stretched upward by the fourth spring body 38, and then the transmission rod 27 continues to resist upward, so that the upper end of the blocking plate 34 The surface of the transmission pipe 362 is in contact with the lower end of the transmission pipe 362. At this time, the snap plate 333 is also snapped on the lower end of the snap groove 334, and then the blocking plate 34 completely blocks the lower end of the transmission pipe 362 and the snap plate 333 completely blocks the lower end of the snap groove 334. The snap plate 333, the third pressing plate 313, and the blocking plate 34 can be set to form a completely closed state, and the newly-flown liquid medicine is completely sealed in the support tube 13. Under the continued upward contact of the transmission rod 27, the second pressing plate 31 and The sliding rod 32 is resisted by the blocking plate 34 and the buckling plate 333, so that the sliding rod 32 slides upward in the sliding hole 331 and presses upward on the third spring body 332. At the same time, the sliding rod 32 drives the bearing rod 312 and the third pressing plate 313 to continue to move upward, so that the pressing plate 313 presses the liquid medicine upward. When the pressing plate 313 slides upward, it slides upward on the outside of the pressing rod 33 through the sleeve hole 314. Due to the arrangement of the second pressing plate 31, the blocking plate 34 and the third pressing plate 313, the liquid medicine is in a sealed state. The pressure generated squeezes the medicine into the inclined tube 39 through the second pressure plate 31. In order to prevent the medicine from flowing into the interior of the delivery tube 12 during the extrusion of the medicine, the first pressure plate 271, the second pressure plate 31, and the third pressure plate 313 are provided. The medicine passing through the third pressure plate 313 and the second pressure plate 31 can effectively flow to the upper end surface of the first pressure plate 271, thereby preventing the medicine from flowing into the interior of the delivery tube 12 and also preventing the medicine from corroding the components and the inner surface of the delivery tube 12, thereby increasing the service life.

[0038] like Figure 6 , Figure 7 As shown, a closed slot 311 is provided in the middle of the upper end surface of the second pressure plate 31, and the upper end surface of the second pressure plate 31 is evenly connected with supporting rods 312 in an equiangular ring shape, and the upper end surfaces of multiple supporting rods 312 are all connected to the third pressure plate 313, and a sleeve hole 314 is provided in the middle of the third pressure plate 313, and the sleeve hole 314 is sleeved on the outside of the pressure rod 33, and the outer side of the upper end of the sliding rod 32 is inserted into the sleeve hole 314.

[0039] The above scheme is adopted: the sliding rod 32 drives the bearing rod 312 and the third pressing plate 313 to continue to move upward, so that the pressing plate 313 squeezes the liquid medicine upward, and the pressing plate 313 slides upward on the outside of the pressing rod 33 through the sleeve hole 314 during the upward sliding. The sleeve hole 314 is provided with a rubber sleeve to avoid leakage caused by the sleeve hole 314 sliding in the pressing rod 33. Through the arrangement of the third pressing plate 313, the solid dirt can be transported to the mixing tank 11 by pressure and then discharged, which can effectively prevent the fixed dirt from clogging the port of the inclined pipe 39 and continue to maintain patency.

[0040] like Figure 8 As shown, the upper part of the pressure rod 33 is fixedly connected with a snap-fit ​​plate 333, and the upper end surface of the snap-fit ​​plate 333 is snap-fitted with a snap-fit ​​slot 334. The snap-fit ​​slot 334 is opened in the middle of the closing plate 335, and the outer annular surface of the closing plate 335 is fixedly connected to the upper part of the inner wall of the support tube 13, and the outer side of the upper part of the pressure rod 33 is inserted into the snap-fit ​​slot 334.

[0041] The above scheme is adopted: as the transmission rod 27 continues to resist upward, the upper end surface of the blocking plate 34 is allowed to resist the lower end of the transmission pipe 362. At this time, the snap plate 333 has also been snapped into the lower end of the snap groove 334, and then the blocking plate 34 completely blocks the lower end of the transmission pipe 362 and the snap plate 333 completely blocks the lower end of the snap groove 334. The snap plate 333, the third pressure plate 313, and the blocking plate 34 can be set to form a completely closed state, so that the third pressure plate 313 pushes the medicine liquid, which is beneficial for the third pressure plate 313 to scrape off the dirt attached to the sealed space through the outer ring surface of the third pressure plate 313 during the reciprocating work, and can automatically clean it to prevent the medicine liquid from being contaminated, thereby improving practicality and functionality.

[0042] like Fig.10 , Fig.11 As shown, the stirring mechanism 4 includes an output rod 41 fixedly connected to the upper end face of the cam 23, a partition 112 is inserted into the lower end of the output rod 41, stirring rods 42 are evenly connected to the outer side of the upper part of the output rod 41 in an equiangular ring, and a plurality of stirring rods 42 are evenly connected to the outer side of the output rod 41 at equal distances along the length direction of the output rod 41, and a scraper 43 is connected to one end of the stirring rod 42, and a side surface of the scraper 43 abuts against the inside of the stirring tank 11, and a drug discharge pipe 44 is connected to the middle of the outer side of the stirring tank 11, and a cap 45 is buckled at one end of the drug discharge pipe 44.

[0043] The above scheme is adopted: when the medicine liquid is delivered, at the same time, the cam 23 has driven the output rod 41 to rotate in a circle, and the output rod 41 drives the stirring rod 42 and the scraper 43 to rotate to stir the delivered medicine liquid. After stirring, the cap 45 is opened, and the stirred medicine liquid is collected to the medical tool through the medicine discharge pipe 44. During cleaning, the medicine liquid can be replaced with disinfectant water, and the pressure mechanism 3 and the lifting mechanism 2 are started to make the upper interior of the support tube 13 self-cleaned, and then the disinfectant water is transmitted to the inside of the stirring tank 11, and then the scraper 43 is used to hang and remove the medicine liquid attached to the stirring tank 11, and the cleaned dirt is discharged into the medicine discharge pipe 44, which can automatically clean the sealed space inside the upper part of the support tube 13, and can effectively prevent the medicine liquid from adhering to the inside of the stirring tank 11, and it also prevents the new medicine liquid from being contaminated, thereby improving the cleanliness.

[0044] like Fig.10 As shown, the two conveying pipes 12 and the stirring tank 11 are connected to each other with an inclined pipe 39, and the high part of one end of the inclined pipe 39 is connected to the outside of the conveying pipe 12, and the low part of the other end of the inclined pipe 39 is connected to the outside of the stirring tank 11.

[0045] The above solution is adopted: since the inclined tube 39 is arranged inclined, it can effectively prevent the medicine liquid from remaining in the inclined tube 39, and there is no need to clean it, thereby avoiding contamination of the medicine liquid.

[0046] like Fig. 9 As shown, a transmission pipe 362 is connected in the middle of the fixing plate 36 , and the upper end of the transmission pipe 362 is buckled into the buckling port 141 at the lower end of the anesthesia tank 14 .

[0047] The above solution is adopted: the liquid medicine in the stirring tank 11 and the dilution tank 15 completely enters the inner upper end of the support tube 13 by buckling, thereby avoiding leakage.

[0048] like Figure 3 As shown, a stirring space is formed between the upper end surface of the partition 112 and the upper inner portion of the stirring tank 11 .

[0049] Adopt the above solution: through the special space, the liquid medicine can be more fully stirred and discharged.

[0050] The working principle and use process of the present invention:

[0051] First, the motor 21 is started to drive the rotating shaft 22 to rotate in a circular manner, which drives the cam 23 to rotate. The annular surfaces on both sides of the cam 23 are in contact with the semicircular surfaces of the transmission member 24. The transmission member 24 is subjected to the resistance force of the outer side of the cam 23, so that the transmission member 24 slides inside the conveying pipe 12. During the sliding, the transmission member 24 drives the sliding rod 241 and the tilting block 242. One end of the sliding rod 241 slides in the through hole of the guide plate 25. At the same time, the transmission member 24 is pressed to one side by the first spring body 26. Through the arrangement of the guide plate 25 and the first spring body 26, the sliding rod 241 and the transmission member 24 are prevented from shaking when moving to one side, thereby ensuring that the sliding rod 241 and the tilting block The moving force of 242 is completely transmitted to the lower end of the transmission rod 27, and the cam 23 continues to rotate, and the high point of the outer ring surface of the cam 23 gradually slides on the semicircular surface of the transmission member 24, and the sliding rod 241 and the tilting block 242 continue to move to one side, and the lower end of the transmission rod 27 gradually moves upward through the inclined surface of the tilting block 242. In the upward process, the upper end of the transmission rod 27 slides in the inner hole of the limit plate 131, and at the same time, it is stretched upward on the second spring body 272 through the first pressure plate 271. The upward force of the transmission rod 27 is resisted by the resistance column 273, so that the second pressure plate 31 is forced to slide upward inside the support tube 13 to avoid displacement during the upward movement of the transmission rod 27.

[0052] When the second pressure plate 31 is forced to slide upward, the elastic force of the third spring body 332 is greater than the elastic force of the fourth spring body 38. Then, the second pressure plate 31 drives the bearing rod 312, the third pressure plate 313, the sliding rod 32, the pressure rod 33, the blocking plate 34, the buckling plate 333, the guide rod 35, and the annular plate 37 to move upward. At the same time, the annular plate 37 is stretched upward by the fourth spring body 38. Then, the transmission rod 27 continues to resist upward, so that the upper end surface of the blocking plate 34 is in contact with the lower end of the transmission pipe 362. At this time, the buckling plate 333 is also buckled in the buckling groove 334. The lower port of the transmission pipe 362 is completely blocked by the blocking plate 34 and the lower port of the locking notch 334 is completely blocked by the locking plate 333. The locking plate 333, the third pressing plate 313 and the blocking plate 34 can form a completely closed state, and the newly-flown liquid medicine is completely sealed in the support tube 13 (before starting, the high points of the annular surfaces on both sides of the cam 23 are in contact with the semicircular surface of the transmission member 24, so that the blocking plate 34 completely blocks the lower port of the transmission pipe 362, and is in the original working state. After starting, the outer side surface of the cam 23 first passes through the high point, and the blocking plate 34 returns to the fourth spring body 38 The lower end of the transmission pipe 362 is opened to allow the liquid medicine to flow to the upper end surface of the second pressure plate 31 inside the support tube 13, thereby realizing that the liquid medicine automatically flows into the interior of the support tube 13, and preparing for the liquid medicine delivery). Then, the transmission rod 27 continues to resist upward, and the second pressure plate 31 and the sliding rod 32 are resisted by the blocking plate 34 and the locking plate 333, so that the sliding rod 32 slides upward in the sliding hole 331 and is pressed upward on the third spring body 332. At the same time, the sliding rod 32 drives the bearing rod 312 and the third pressure plate 313 to continue to move upward, so that the pressure plate 313 is pressed upward. To compress the medicine liquid, the pressing plate 313 slides upward through the sleeve hole 314 on the outside of the pressing rod 33. Due to the arrangement of the second pressing plate 31, the blocking plate 34 and the third pressing plate 313, the medicine liquid is in a sealed state. The pressure generated squeezes the medicine liquid into the inclined tube 39 through the second pressing plate 31. The third pressing plate 313 continues to press the medicine liquid upward until the upper end surface of the third pressing plate 313 is pressed against the lower end surface of the snap plate 333 and the lower end surface of the closing plate 335. At the same time, the lower end surface of the pressing rod 33 penetrates into the bottom of the closing slot 311, and can completely squeeze the sealed medicine liquid into the inclined tube 39 and the stirring tank 11.

[0053] When the medicine liquid is delivered, at the same time, the cam 23 has driven the output rod 41 to rotate in a circle, and the output rod 41 drives the stirring rod 42 and the scraper 43 to rotate to stir the delivered medicine liquid. After stirring, open the cap 45, and collect the stirred medicine liquid to the medical tool through the medicine discharge pipe 44. During cleaning, the medicine liquid can be replaced with disinfectant water, and the pressure mechanism 3 and the lifting mechanism 2 are started to make the upper interior of the support tube 13 self-clean, and then the disinfectant water is transmitted to the inside of the stirring tank 11, and then the scraper 43 is used to scrape off the medicine liquid attached to the stirring tank 11, and the dirt after cleaning is discharged into the medicine discharge pipe 44.
