[0003] There are many inconveniences in the existing design for fixing and replacing infusion bottles. When nurses replace infusion bottles, the operation is often cumbersome and lacks a flexible and effective fixing and disassembly mechanism. The manual replacement method may have high requirements on the nurse's strength, which is difficult for nurses with less strength to operate; and some existing auxiliary disassembly devices are not perfect and may not ensure the stable disassembly of the infusion bottle, which may easily cause the infusion bottle to fall and the cone needle of the infusion device to be pulled and damaged.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, liquid flows into the rotating chamber through the conical introduction section, and the inner wall of the rotating chamber is provided with an exhaust channel. When the liquid passes through, it will generate a rotating motion, and the centrifugal force is used to make the bubbles gather to the edge of the rotating chamber. The bubble gathering groove is located at the edge of the inner wall of the rotating chamber. The bubble gathering groove is an annular groove. The gathered bubbles will enter this groove. The spiral guide groove is connected to the bubble gathering groove. A one-way valve is provided in the spiral guide groove, which only allows gas to be discharged to prevent liquid leakage. By adopting the combination of the conical introduction section and the rotating chamber, the bubbles in the liquid can be quickly discharged during infusion, thereby improving the exhaust capacity of the infusion device body.

[0014] In the present invention, the arc-shaped concave plate moves downward to drive the transmission plate frame to move downward, and the transmission plate frame moves downward to drive the first bar gear to move forward through the first gear and the second gear, and the first bar gear moves forward and is inserted into the bottle mouth of the infusion bottle. At this time, the infusion bottle and the bottle removal rack are fixed. When the nurse needs to disassemble and replace the infusion bottle, the nurse can directly pull the infusion bottle upward, or squeeze the air bag multiple times. The air bag fills air into the air pressure column, and the air pressure column pushes the infusion bottle upward through the air pressure plug. By adopting two replacement methods, it can meet the needs of nurses to manually replace the infusion bottle, and it can also meet the needs of nurses who are not strong enough to disassemble it, which greatly improves the replaceability of the infusion bottle.

[0015] In the present invention, when the second bar gear moves downward and contacts the first gear, the movement of the second bar gear drives the first gear to rotate, the rotation of the first gear drives the main shaft to rotate, the rotation of the main shaft drives the second gear to rotate synchronously, the rotation of the second gear drives the first bar gear to move forward, the two first bar gears move forward and are plugged into the flat-mouthed concave and convex parts of the infusion bottle. At this time, the infusion bottle is fixed by two arc-shaped concave plates and the first bar gear. The two arc-shaped concave plates are used to position the infusion bottle, which can ensure that the cone needle of the infusion device is inserted in one time to prevent deviation, and at the same time ensure that the bottle mouth of the infusion bottle is accurately moved to a fixed position.

[0016] In the present invention, the movement of the infusion bottle drives the movement of the arc-shaped concave plate, which can improve the applicability of the arc-shaped concave plate to different infusion bottles, and the infusion bottle drives the arc-shaped concave plate to move downward, and then drives the first bar gear to move horizontally, which can improve the automation of the entire device and ensure the connectivity between the infusion bottle and the bottle removal rack when the infusion bottle moves downward, and when the infusion bottle moves upward, the first bar gear can be kept automatically disengaged.

[0017] In the present invention, the bottle pushing stand moves upward to push the bottle mouth of the infusion bottle upward, and the air pressure plug and the bottle pushing stand are used to push the bottle mouth of the infusion bottle in two places, thereby improving the ability to disassemble the infusion bottle and ensuring that the infusion bottle can be successfully disassembled at one time. The air bag is inflated to disassemble the infusion bottle, and the infusion bottle and the infusion set cone needle can be slowly separated. During manual separation, the infusion bottle will not fall due to excessive force, or the infusion set cone needle will not pull the infusion set body when pulling out. There will also be no phenomenon that a nurse with too little strength will have difficulty in pulling out the infusion set cone needle. The method of slowly disassembling the infusion set cone needle can ensure that the infusion bottle is stably disassembled without affecting the infusion set body.

[0018] In the present invention, when the two air pressure plugs on the bottle removal rack use force to disassemble the infusion bottle, the first set of plates and the second set of plates play a stabilizing role, and the two tension rods between the first set of plates and the second set of plates can play a stretching and fixing role, preventing the bottle removal rack from affecting the infusion device body when disassembling the infusion bottle, and at the same time can further improve the stability of the infusion bottle when disassembling.

The user squeezes the airbag 22 by hand for many times, and the airbag 22 is forced to inflate the inside of the two air pressure columns 23 through the air inlet pipe 21. The air pressure inside the two air pressure columns 23 increases, driving the air pressure plug 24 to move upward, and the top of the air pressure plug 24 pushes the infusion bottle 19 upward, and the air pressure plug 24 passes The arc-shaped connecting rod 25 drives the bottle pushing rack 26 to move upward, and the bottle pushing rack 26 moves upward to push the bottle mouth of the infusion bottle 19 upward.

The first set of plates 11 and the second set of plates 12 are used to fix the bottle removing rack 2. The first bar gear 29 runs through both sides of the multi-groove slide 27. When the infusion device cone needle 38 is inserted into the U-shaped groove 39, the first bar gear 29 is inserted into the joint of the bottle mouth of the infusion bottle 19.

[0034] Working principle:

[0035] In the first step, when using the infusion bottle 19 for infusion, the infusion enters the conical introduction section 14. The gradually narrowing structure of the front end of the conical introduction section 14 accelerates the flow rate of the liquid. The liquid flows into the rotating chamber 15 through the conical introduction section 14. The inner wall of the rotating chamber 15 is provided with an exhaust channel 18. The liquid will produce a rotational motion when passing through, and the centrifugal force is used to make the bubbles gather to the edge of the rotating chamber 15. The bubble gathering groove 17 is located at the edge of the inner wall of the rotating chamber 15. The bubble gathering groove 17 is an annular groove. The gathered bubbles will enter this groove. The spiral guide groove 16 is connected to the bubble gathering groove 17. A one-way valve is provided in the spiral guide groove 16, which only allows gas to be discharged to prevent liquid leakage. By adopting the cooperation of the conical introduction section 14 and the rotating chamber 15, the bubbles in the liquid can be quickly discharged during infusion, thereby improving the exhaust capacity of the infusion device body 1.

[0036] When the nurse is plugging the infusion set cone needle 38 and the infusion bottle 19, the nurse holds the connector 37 and moves the infusion bottle 19 downward. The bottle mouth of the infusion bottle 19 is located between the two arc-shaped concave plates 36. The infusion bottle 19 is pressed downward continuously. The infusion bottle 19 is inserted into the infusion set cone needle 38. At the same time, the infusion bottle 19 pushes the two arc-shaped concave plates 36 downward. The arc-shaped concave plates 36 move downward and drive the transmission plate frame 31 to move downward. The transmission plate frame 31 moves downward and drives the first bar gear 29 to move forward through the first gear 34 and the second gear 35. The first bar gear 29 moves forward. The gear 29 moves forward and is inserted into the bottle mouth of the infusion bottle 19. At this time, the infusion bottle 19 and the bottle removal rack 2 are fixed. When the nurse needs to disassemble and replace the infusion bottle 19, the nurse can directly pull the infusion bottle 19 upward, or squeeze the air bag 22 multiple times. The air bag 22 fills air into the air pressure column 23, and the air pressure column 23 pushes the infusion bottle 19 upward through the air pressure plug 24. By adopting two replacement methods, it can not only meet the nurse's manual replacement of the infusion bottle 19, but also meet the nurse's lack of strength to disassemble it, which greatly improves the replaceability of the infusion bottle 19.

[0037] The second step is that when the infusion bottle 19 moves downward, the two arc-shaped concave plates 36 are forced to move downward, and the two arc-shaped concave plates 36 move downward to drive the transmission plate frame 31 to move downward, and the two transmission plate frames 31 move downward to drive the second bar gear 32 to move downward. When the second bar gear 32 moves downward and contacts the first gear 34, the second bar gear 32 moves to drive the first gear 34 to rotate, and the rotation of the first gear 34 drives the main shaft 33 to rotate, and the rotation of the main shaft 33 drives the second gear 35 to rotate synchronously, and the rotation of the second gear 35 drives the first bar gear 29 to move forward, and the two first bar gears 29 move forward to be plugged into the flat concave and convex part of the infusion bottle 19. At this time, the infusion bottle 19 is fixed by the two arc-shaped concave plates 36 and the first bar gear 29. The two arc-shaped concave plates 36 are used to position the infusion bottle 19, which can ensure that the infusion device cone needle 38 is inserted once to prevent deviation, and at the same time, it can ensure that the bottle mouth of the infusion bottle 19 is accurately moved to the fixed position;

[0038] The movement of the infusion bottle 19 drives the movement of the arcuate concave plate 36, which can improve the applicability of the arcuate concave plate 36 to different infusion bottles 19. The infusion bottle 19 drives the arcuate concave plate 36 to move downward, and then drives the first bar gear 29 to move horizontally, which can improve the automation of the entire device and ensure the connectivity of the infusion bottle 19 with the bottle removal rack 2 when the infusion bottle 19 moves downward. When the infusion bottle 19 moves upward, the first bar gear 29 can be automatically disengaged.

[0039] In the third step, when the infusion bottle 19 needs to be separated, the user squeezes the airbag 22 several times by hand, and the airbag 22 is forced to inflate the two air pressure columns 23 through the air inlet pipe 21. The air pressure inside the two air pressure columns 23 increases, driving the air pressure plug 24 to move upward, and the top of the air pressure plug 24 pushes the infusion bottle 19 upward. The air pressure plug 24 drives the bottle pusher 26 to move upward through the arc-shaped connecting rod 25. The bottle pusher 26 moves upward to push the bottle mouth of the infusion bottle 19 upward. The air pressure plug 24 and the bottle pusher 26 are used to push the bottle mouth of the infusion bottle 19 at two places, thereby improving the infusion. The ability to disassemble the bottle 19 ensures that the infusion bottle 19 can be successfully disassembled at one time. The airbag 22 is inflated to disassemble the infusion bottle 19, and the infusion bottle 19 and the infusion set cone needle 38 can be slowly separated. There will be no excessive force during manual separation, causing the infusion bottle 19 to fall, or the infusion set cone needle 38 will be pulled when the infusion set cone needle 38 is pulled out. There will also be no phenomenon that the nurse with too little strength will find it difficult to pull out the infusion set cone needle 38. The method of slowly disassembling the infusion set cone needle 38 can ensure that the infusion bottle 19 is stably disassembled without affecting the infusion set body 1.

[0040] When the two air plugs 24 on the bottle removing rack 2 forcefully remove the infusion bottle 19, the first set of plates 11 and the second set of plates 12 play a stabilizing role, and the two tension rods 13 between the first set of plates 11 and the second set of plates 12 can play a stretching and fixing role, preventing the bottle removing rack 2 from affecting the infusion device body 1 when removing the infusion bottle 19, and at the same time can further improve the stability of the infusion bottle 19 when it is removed.

[0041] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
