Description

Technical Field

[0001] The utility model relates to the technical field of infusion tube air exhaust, in particular to a movable gear infusion air exhaust controller. Background Art

[0002] Intravenous infusion is a treatment method of injecting a large amount of sterile solution or drug through a vein. Intravenous infusion utilizes the physical principle of hydrostatic pressure to input the liquid into the body. In clinical practice, intravenous infusion is a common administration route, and disposable infusion tubes have been used clinically for many years as essential devices for intravenous infusion.

[0003] During the infusion process, it is possible that due to inattention, the liquid medicine drips out, causing the liquid medicine to flow into the infusion hose below the Murphy's dropper, and the liquid medicine is lower than the drip chamber, resulting in a large section of air in the infusion tube. If the air is not discharged and a new liquid is continued to be input, it may cause air embolism in severe cases, even endangering life. There are usually two methods for air exhaust: 1 is to directly open the screw interface for air exhaust; 2 is to flatten the infusion hose with the help of other items (such as a pen, finger) and send the liquid medicine and air into the drip chamber little by little; the above two air exhaust methods may cause waste of liquid medicine, contamination of sterile drugs, and at the same time reduce the work efficiency of medical staff. Content of the Utility Model

[0004] In view of the above deficiencies, the utility model provides a movable gear infusion air exhaust controller, which can quickly squeeze the air in the infusion hose through the air exhaust controller and send the air back into the drip chamber, thereby reducing the waste of liquid medicine.

The air exhaust controller 2 is located above the flow rate regulator 14, and the force receiver 3 is located below the flow rate regulator 14. The infusion hose 12 is squeezed and wound by the force receiver 3, thereby preventing the air flow inside the infusion hose 12, and the force receiver 3 can be used as a force application point to facilitate the pushing of the air exhaust controller 2. The air exhaust controller 2 can squeeze the infusion hose 12 to squeeze the air inside the infusion hose 12 back into the drip chamber 15.

[0032] A through groove 31 is provided in the middle of the force receiver 3. The through groove 31 is slidably connected to the infusion hose 12. One end of the force receiver 3 is provided with a first notch 32, and the other end is provided with a second notch 33. The first notch 32 and the second notch 33 are symmetrical.

Flip the force receiver 3 so that the infusion hoses 12 at both ends of the force receiver 3 respectively enter the first notch 32 and the second notch 33, and then rotate the force receiver 3 so that the infusion hoses 12 in the first notch 32 and the second notch 33 are wound in the first pipe groove 34 and the second pipe groove 35. The force receiver 3 can provide a force application point for pushing the exhaust controller 2 while squeezing the infusion hose 12, and the corners of the infusion hose 12 passing through the first notch 32, the second notch 33, the first pipe groove 34 and the second pipe groove 35 are all rounded corners, which can protect the pipeline and avoid damaging the infusion hose 12 due to excessive force.

[0033] Embodiment 2:

[0034] Referring to Figure 1 - Figure 7 As shown, on the basis of Embodiment 1, the exhaust controller 2 includes a housing 21, a pressing plate 22 and a pressing wheel 23. The inside of the housing 21 is hollow. Through holes 211 are provided in the middle of the front and rear ends of the housing 21. The through holes 211 communicate with the inside of the housing 21. The through holes 211 are slidably connected to the infusion hose 12. Openings 212 are provided on the left and right sides of the housing 21. The openings 212 communicate with the inside of the housing 21. Arc-shaped chutes 213 are provided on the left and right sides of the housing 21 inside the openings 212. Both ends of the pressing wheel 23 are provided with support blocks 231. The support blocks 231 are slidably connected in the chutes 213. Pressing plates 22 are provided at the openings 212 on the left and right sides of the housing 21. One end of the pressing plate 22 is fixedly connected to one side of the opening 212, and the pressing wheel 23 can be moved inward along the chute 213 through the pressing plate 22, thereby squeezing the infusion hose 12.

[0035] Among them, an arc plate 221 is provided at the end-to-end connection of the pressing plate 22 and the opening 212. The arc plate 221 is slidably connected to the pressing wheel 23, and the pressing wheel 23 can be pressed against the bottom of the chute 213 through the arc plate 221. The inner side of the arc plate 221 is smooth, and the circumferential side of the pressing wheel 23 is smooth. When the housing 21 is pushed, the pressing wheel 23 can roll on the infusion hose 12, reducing the resistance, and when the pressing wheel 23 rolls on the infusion hose 12, it can avoid damaging the infusion hose 12.

[0036] Among them, a pressing block 222 is provided on the pressing plate 22, which can increase the force application point.

[0040] The working principle of this embodiment is as follows: when air enters the infusion hose 12, the infusion hose 12 is first squeezed by the flow rate regulator 14 to prevent the air from moving further downward, and then the force receiving device 3 is rotated to make the infusion hose 12 in the first notch 32 and the second notch 33 be wound in the first tube groove 34 and the second tube groove 35, and the force receiving device 3 is grasped, and the thumb and index finger of the hand press the pressing plate 22 on both sides of the shell 21, and the pressing plate 22 squeezes the pressing wheel 23, and the pressing wheel 23 moves along the slide groove 213 until the pressing wheel 23 The infusion hose 12 is flattened, and then the shell 21 is pushed. The pressure wheel 23 rolls on the infusion hose 12 to squeeze the air in the infusion hose 12 until the air is squeezed into the drip pot 15. The pressure plate 22 is released, and the pressure plate 22 rebounds. The spring 41 pushes the slider 42 to move, and the slider 42 pushes the pressure wheel 23 to move until it reaches the end of the slide groove 213. The infusion hose 12 is removed from the force bearer 3 through the above-mentioned reverse operation to complete the air removal. The whole process is completed in a closed state to ensure the sterility of the liquid medicine.

[0042] Reference Figure 8 As shown, on the basis of Example 1, the exhaust controller 2 is a second flow rate regulator 24 , and the second flow rate regulator 24 is slidably connected to the infusion hose 12 .

[0043] By adjusting the second flow rate regulator 24, the infusion hose 12 is squeezed until flattened, and the second flow rate regulator 24 is pushed upward, thereby squeezing and pushing the air in the infusion hose 12 and sending the air back into the drip chamber 15 to reduce the waste of the liquid medicine.

[0044] The exhaust controller 2 in this embodiment is the second flow rate regulator 24, and the second flow rate regulator 24 is a common one in the prior art, so its specific detailed structure will not be described.
