Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment and relates to anesthesia equipment for outdoor rescue. Background Art

[0002] Anesthesia is a reversible inhibition of the central and / or peripheral nervous systems produced by drugs or other methods. The main characteristic of this inhibition is the loss of sensation, especially pain. Local anesthesia, also known as regional anesthesia, refers to the application of local anesthetics to a part of the body while the patient is conscious, so that the sensory nerve conduction function of a part of the body is temporarily blocked, while the motor nerve conduction remains intact or is blocked to varying degrees. This blockade should be completely reversible and does not cause any tissue damage. Local anesthesia is often used in outdoor rescue.

[0003] A local anesthesia device disclosed in Chinese patent CN219836008U is provided with a driving mechanism, so that when in use, a micro motor can be started to drive a threaded rod to rotate, and the threaded rod drives the injection tube in the sleeve to slide in the sleeve, and then the sliding of the slide rod can resist the piston sliding on the inner side of the injection tube, so as to push the medicine. During use, since the motor is used to drive the medicine each time, each push of the medicine is more balanced and uniform. At the same time, the injection of the medicine does not need to be done manually, so that during use, the doctor only needs to hold the injection tube by hand, thereby facilitating the injection of the medicine.

[0004] The anesthesia device directly injects the anesthetic agent into the syringe.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] Example 1

The outer surface of the dilution tube 3 is fixedly connected with a liquid inlet 22 and a liquid outlet 16 in sequence from top to bottom. A blocking block 6 is detachably connected to the liquid inlet 22.

[0045] The bottom of the injection tube 1 is fixedly connected with a needle 12, which is connected to the inner cavity of the injection tube 1. A threaded section is provided on the outer surface of the bottom of the injection tube 1, and a positioning cap 4 is threadedly sleeved on the threaded section.

[0046] A discharge assembly is disposed at the bottom of the liquid outlet 16 , and the liquid outlet 16 is detachably connected to the needle 12 via the discharge assembly.

[0047] The discharge assembly includes a connecting tube 13, the top of which is fixedly connected to the liquid outlet 16. The connecting tube 13 is fixedly passed through the partition 2, and the bottom of the connecting tube 13 is fixedly connected to a connector 14 through a telescopic tube, and the connector 14 cooperates with the needle 12.

[0048] A clamping block 15 is fixedly connected to the outer surface of the injection tube 1 , and the connector 14 is clamped on the clamping block 15 .

[0049] A sealing assembly is provided inside the liquid outlet 16. The sealing assembly includes a slide bar 17 and a sphere 18. The slide bar 17 slides through the liquid outlet 16. The sphere 18 is fixedly connected to one end of the slide bar 17 close to the dilution tube 3. The dilution tube 3 is provided with a liquid outlet hole adapted to the sphere 18.

[0050] The end of the slide bar 17 extending out of the liquid outlet 16 is fixedly connected to a limit plate, a spring 19 is fixedly connected between the limit plate and the outer side surface of the liquid outlet 16 , and the slide bar 17 passes through the spring 19 .

[0051] The inside of the dilution tube 3 is rotatably connected with a stirring rod 7. The top of the dilution tube 3 is fixedly connected with a micro motor 5, which drives the stirring rod 7 to rotate.

[0052] The bottom end of the stirring rod 7 rotates to penetrate the bottom surface of the dilution tube 3. A transmission assembly is arranged at the bottom of the stirring rod 7, and the transmission assembly drives the piston 11 to slide up and down inside the injection tube 1.

[0053] The transmission assembly comprises a threaded rod 8 and a sliding sleeve 9, wherein the sliding sleeve 9 is threadedly sleeved on the threaded rod 8. The threaded rod 8 is fixedly connected to the bottom of the stirring rod 7, and the sliding sleeve 9 is fixedly connected to the top of the piston 11.

[0054] A fixed sleeve 10 is fixedly connected to the partition plate 2 , the bottom of the fixed sleeve 10 extends into the injection tube 1 , and the sliding sleeve 9 is slidably connected to the inside of the fixed sleeve 10 .

[0055] Two positioning grooves are symmetrically provided on the inner wall of the fixed sleeve 10 , and two positioning bars are fixedly connected to the outer surface of the sliding sleeve 9 , and the two positioning bars are slidably connected to the corresponding positioning grooves respectively.

[0056] Working principle:

[0057] When the anesthetic agent needs to be diluted, the block 6 is opened, and the agent and physiological saline are injected into the dilution tube 3 through the liquid inlet 22. After the injection, the liquid inlet 22 is sealed with the block 6.

[0058] The micro motor 5 is started to drive the stirring rod 7 to rotate forward, so that the stirring rod 7 stirs and mixes the medicine and the physiological saline.

[0059] The stirring rod 7 will drive the threaded rod 8 to rotate forward, so that the threaded rod 8 rotates in the sliding sleeve 9. Since two positioning grooves are symmetrically provided on the inner wall of the fixed sleeve 10, two positioning bars are fixedly connected on the outer surface of the sliding sleeve 9, and the two positioning bars are respectively slidably connected in the corresponding positioning grooves. Through the limiting of the positioning bars and the positioning grooves, the sliding sleeve 9 slides downward in the fixed sleeve 10. The sliding sleeve 9 will push the piston 11 to slide downward in the injection tube 1. The gas at the bottom of the injection tube 1 is discharged through the needle 12.

[0060] When the piston 11 slides to the bottom of the syringe 1, the micro motor 5 drives the stirring rod 7 and the threaded rod 8 to reverse, so that the sliding sleeve 9 slides upward in the fixed sleeve 10, the positioning bar slides upward in the positioning groove, and the sliding sleeve 9 pulls the piston 11 to slide upward. The syringe 1 is evacuated through the needle 12.

[0061] During the stirring process of the stirring rod 7 , the piston 11 slides up and down in the injection tube 1 .

[0062] After the medicines are mixed in the dilution tube 3, the piston 11 is first moved to the bottom of the injection tube 1, and the micro motor 5 is turned off. The connector 14 is removed from the block 15, and the connector 14 is pulled downward to extend the telescopic tube at the connection between the connecting tube 13 and the connector 14. The connector 14 is installed at the bottom end of the needle 12.

[0063] The micro motor 5 is started to drive the stirring rod 7 to reverse, and the stirring rod 7 continues to stir the medicine while driving the threaded rod 8 to reverse, so that the threaded rod 8 rotates in the sliding sleeve 9. The sliding sleeve 9 slides upward in the fixed sleeve 10, pulling the piston 11 to slide upward in the injection tube 1.

[0064] The piston 11 moves upward, and the injection tube 1 will extract the air in the connecting tube 13 through the needle 12. Since the top of the connecting tube 13 is connected to the liquid outlet 16, the ball 18 will shake. The ball 18 and the slide bar 17 will slide to the side away from the dilution tube 3 and stretch the spring 19. There is a gap between the ball 18 and the liquid outlet of the dilution tube 3, which will allow the medicine in the dilution tube 3 to pass through the liquid outlet at the ball 18 and enter the liquid outlet 16. The medicine will enter the injection tube 1 through the connecting tube 13 and the needle 12, which is convenient for subsequent injection. The staff does not need to extract medicine and saline multiple times, which reduces the workload.

[0065] After all the medicine in the dilution tube 3 enters the injection tube 1, the micro motor 5 is turned off, the piston 11 stops moving upward, and the needle 12 stops pumping air. Under the elastic force of the spring 19, the slide bar 17 is pushed into the liquid inlet 22 until the ball 18 blocks the liquid outlet of the dilution tube 3. The connector 14 is removed from the needle 12, and the connector 14 is clamped on the clamping block 15, and the telescopic tube returns to its original state.

[0066] Since the medicine entering the syringe 1 contains gas, the whole device is inverted so that the needle 12 faces upward. At this time, the medicine is located below the gas under the action of gravity. The micro motor 5 is started to drive the stirring rod 7 to rotate forward, so that the piston 11 slides in the syringe 1 toward the end close to the positioning cap 4. The piston 11 squeezes the gas in the syringe 1 and discharges the gas through the needle 12.

[0067] The positioning cap 4 is rotated according to the injection situation to change the length of the needle 12 extending out of the positioning cap 4, so that the positioning cap 4 slides on the needle 12 and the injection length of the needle 12 is adjusted so that the side of the positioning cap 4 away from the injection tube 1 is close to the skin during injection, which can help improve the stability of the injection.

[0068] During injection, the micro motor 5 is started to drive the stirring rod 7 to rotate forward, so that the piston 11 slides in the injection tube 1 toward the end close to the positioning cap 4, so that the piston 11 pushes the medicine, and the medicine flows out from the needle 12.

[0069] Example 2

[0070] like Figure 5-Figure 7 As shown, the anesthesia equipment for outdoor rescue includes an injection tube 1, a partition 2 is fixedly connected to the top of the injection tube 1, and a mounting tube 23 is fixedly connected to the top of the partition 2. A micro motor 5 with dual output shafts is fixedly connected to the bottom surface of the inner cavity of the mounting tube 23, and a square block 20 is fixedly connected to the top of the output shaft at the top of the micro motor 5.

[0072] The transmission assembly includes a threaded rod 8 and a sliding sleeve 9, and the sliding sleeve 9 is threadedly sleeved on the threaded rod 8. The threaded rod 8 is fixedly connected to the bottom end of the output shaft at the bottom of the micro motor 5, and the sliding sleeve 9 is fixedly connected to the top of the piston 11.

[0073] A fixed sleeve 10 is fixedly connected to the partition plate 2 , the bottom of the fixed sleeve 10 extends into the injection tube 1 , and the sliding sleeve 9 is slidably connected to the inside of the fixed sleeve 10 .

[0074] Two positioning grooves are symmetrically provided on the inner wall of the fixed sleeve 10 , and two positioning bars are fixedly connected to the outer surface of the sliding sleeve 9 , and the two positioning bars are slidably connected to the corresponding positioning grooves respectively.

[0075] The bottom of the injection tube 1 is fixedly connected with a needle 12. A threaded section is provided on the outer surface of the bottom of the injection tube 1, and a positioning cap 4 is threadedly sleeved on the threaded section. The bottom end of the needle 12 passes through the positioning cap 4, and the height of the positioning cap 4 is greater than the length of the needle 12.

[0076] The top of the mounting tube 23 is internally provided with a dilution tube 3, and the inside of the dilution tube 3 is rotatably connected with a stirring rod 7, and the bottom end of the stirring rod 7 extends to the outside of the dilution tube 3. The inner wall of the bottom end of the stirring rod 7 cooperates with the needle 12, and the outer surface of the bottom end of the stirring rod 7 cooperates with the square block 20 in a sliding manner.

[0077] A liquid inlet hole is provided on the stirring rod 7 and runs through the stirring rod 7 from top to bottom. A sealing component is provided at the top of the liquid inlet hole.

[0078] The sealing assembly includes a sphere 18 and a slide rod 17. The sphere 18 is fixedly connected to the top end of the slide rod 17, and the sphere 18 is matched with the top end of the liquid inlet hole.

[0079] A fixing rod 21 is fixedly connected inside the liquid inlet hole, the width of which is smaller than the diameter of the liquid inlet hole, and the fixing rod 21 is located below the slide bar 17. A spring 19 is fixedly connected between the top surface of the fixing rod 21 and the bottom of the sphere 18, and the slide bar 17 passes through the spring 19.

[0080] The dilution tube 3 is provided with a liquid inlet 22 , and the liquid inlet 22 is provided with a one-way valve.

[0081] Working principle:

[0082] When the anesthetic agent needs to be diluted, the agent and physiological saline are injected into the dilution tube 3 through the liquid inlet 22 .

[0083] The micro motor 5 is started to rotate the output shaft at the top and the output shaft at the bottom of the micro motor 5 forward. The output shaft at the top of the micro motor 5 drives the square block 20 to rotate forward, so that the stirring rod 7 rotates forward, and the stirring rod 7 stirs and mixes the medicine and the physiological saline in the dilution tube 3.

[0084] The output shaft at the bottom of the micro motor 5 will drive the threaded rod 8 to rotate forward, so that the threaded rod 8 rotates in the sliding sleeve 9. Since two positioning grooves are symmetrically provided on the inner wall of the fixed sleeve 10, two positioning bars are fixedly connected on the outer surface of the sliding sleeve 9, and the two positioning bars are respectively slidably connected in the corresponding positioning grooves. Through the limiting of the positioning bars and the positioning grooves, the sliding sleeve 9 slides downward in the fixed sleeve 10. The sliding sleeve 9 will push the piston 11 to slide downward in the syringe 1, so that the gas at the bottom of the syringe 1 is discharged through the needle 12.

[0085] When the piston 11 slides to the bottom of the syringe 1, the output shaft at the top and the output shaft at the bottom of the micromotor 5 reverse. The output shaft at the bottom of the micromotor 5 drives the threaded rod 8 to reverse, so that the sliding sleeve 9 pulls the piston 11 to slide upward in the syringe 1, and the syringe 1 draws air through the needle 12. The output shaft at the top of the micromotor 5 drives the stirring rod 7 to reverse, so that the stirring rod 7 continues to stir. Then, during the stirring process of the stirring rod 7, the piston 11 slides up and down in the syringe 1.

[0086] After the stirring rod 7 completes stirring of the medicine and saline in the dilution tube 3, the piston 11 is first moved to the bottom of the injection tube 1, and the micro motor 5 is turned off. The dilution tube 3 is lifted upward, and the bottom end of the stirring rod 7 is removed from the square block 20. After removal, the stirring rod 7 is turned upside down, that is, the end of the stirring rod 7 extending out of the dilution tube 3 is facing upward.

[0087] Move the syringe 1 and insert the needle 12 into the stirring rod 7. Start the micro motor 5 to drive the square block 20 and the threaded rod 8 to reverse, so that the piston 11 moves upward, and the air in the liquid inlet hole on the stirring rod 7 is extracted through the needle 12. At this time, the pressure in the liquid inlet hole decreases, the ball 18 and the slide bar 17 move toward the direction close to the fixed rod 21, and compress the spring 19, so that the ball 18 will not block the liquid inlet hole. The medicine in the dilution tube 3 will enter the syringe 1 through the liquid inlet hole and the needle 12.

[0088] After the injection of the medicine is completed, the micro motor 5 is turned off and the piston 11 does not move. Under the action of the elastic force of the spring 19, the sliding rod 17 and the ball 18 are pushed away from the fixed rod 21, so that the ball 18 blocks the liquid inlet hole. Then the stirring rod 7 is removed from the needle 12.

[0089] Since the medicine entering the syringe 1 contains gas, the whole device is inverted so that the needle 12 faces upward. At this time, the medicine is located below the gas under the action of gravity. The micro motor 5 is started to drive the square block 20 and the threaded rod 8 to rotate forward, and the piston 11 slides in the syringe 1 toward the end close to the positioning cap 4. The piston 11 squeezes the gas in the syringe 1 and discharges the gas through the needle 12.

[0090] After discharge, the positioning cap 4 is rotated according to the injection situation to make the positioning cap 4 slide on the needle 12, change the length of the needle 12 extending out of the positioning cap 4, and adjust the injection length of the needle 12 so that the side of the positioning cap 4 away from the injection tube 1 is close to the skin during injection, which can help improve the stability of the injection.

[0091] During injection, the micro motor 5 is started to drive the threaded rod 8 to rotate forward, so that the piston 11 pushes the medicine, and the medicine flows out from the needle 12.
