[0022] Specifically, the alarm-type liquid retention infusion terminator comprises an infusion clamp 1. The infusion clamp 1 is an existing clamp that can be clamped on the outside of the infusion tube. An alarm component is arranged on the infusion clamp 1. Both sides of the bottom of the infusion clamp 1 are fixedly connected with fixed frames 2. The two fixed frames 2 are symmetrically fixed under the clamp arms on both sides of the infusion clamp 1. A termination component is arranged in the fixed frame 2. A trigger component in contact with the infusion tube is arranged in the infusion clamp 1. A switch unit for controlling the operation of the alarm component and the termination component is also arranged in the infusion clamp 1. When negative pressure appears in the infusion tube, the trigger component controls the operation of the alarm component and the termination component through the switch unit to stop the infusion. The alarm component The medical staff can be reminded to provide services to the patient, and the termination component can terminate the infusion tube when there is a certain amount of retained fluid in the infusion tube to prevent the gas in the infusion bottle from entering the patient's body through the infusion tube and causing certain harm. The termination component includes a moving rod 301 slidably connected to the fixed frame 2, and a magnetic plate 302 and an extrusion block 303 are fixedly connected to the moving rod 301. An electromagnet 304 is fixedly connected to the fixed frame 2. The electromagnet 304 is magnetic when energized and can attract the magnetic plate 302, so that the magnetic plate 302 drives the extrusion block 303 to move through the moving rod 301, thereby realizing the clamping and termination operation of the infusion tube.

[0023] In an embodiment further provided by the present invention, a spring 305 is provided between the fixing frame 2 and the magnetic plate 302 , and the elastic force of the spring 305 drives the magnetic plate 302 away from the electromagnet 304 .

[0024] Preferably, a spring 305 is provided between the fixed frame 2 and the magnetic plate 302, and the elastic force of the spring 305 drives the magnetic plate 302 away from the electromagnet 304. When the electromagnet 304 is powered off, the electromagnet 304 loses its magnetism. At this time, the restoring force of the spring 305 can drive the magnetic plate 302 adhered to the electromagnet 304 to move, thereby making the extrusion blocks 303 on both sides move away from each other synchronously, thereby releasing the termination operation on the infusion tube.

[0025] In an embodiment further provided by the present invention, the alarm component includes a warning light 401 and an alarm 402 arranged on the infusion clamp 1 .

[0026] Preferably, the alarm component includes a warning light 401 and an alarm 402 arranged on the infusion clamp 1. The warning light 401 and the alarm 402 are both existing equipment and will not be described in detail here. The warning light 401 helps medical staff to quickly find patients who need to be reset, and the alarm 402 is to remind medical staff that the patient needs service.

[0027] In an embodiment further provided by the utility model, the trigger assembly includes an elastic telescopic rod 501 arranged in the infusion clamp 1, and a movable plate 502 is fixedly connected to the elastic telescopic rod 501; a column 503 and a trigger rod 504 are fixedly connected to the movable plate 502, and a contact ball 505 is arranged on the column 503.

[0028] Preferably, the trigger assembly includes an elastic telescopic rod 501 arranged in the infusion clamp 1, and a movable plate 502 is fixedly connected to the elastic telescopic rod 501; a column 503 and a trigger rod 504 are fixedly connected to the movable plate 502, and a contact ball 505 is arranged on the column 503. When the infusion tube is in normal infusion mode, the infusion tube is in a saturated state. At this time, the resistance of the infusion tube to the contact ball 505 is greater than the deformation of the elastic telescopic rod 501. The infusion tube abuts the contact ball 505 and moves toward the inside of the infusion clamp 1, causing the elastic telescopic rod 501 to deform.

[0029] In an embodiment further provided by the present invention, the switch unit includes a contact switch 6 arranged in the switch unit.

[0030] Preferably, the switch unit includes a contact switch 6 arranged in the switch unit. After the contact switch 6 is squeezed, the alarm 402, the warning light 401 and the electromagnet 304 are controlled to be energized synchronously to make the termination component work so that the gas and liquid inside the infusion tube do not flow.

[0031] In an embodiment further provided by the present invention, an extension rod 701 is disposed outside the infusion clamp 1 , and a pipe clamp 702 is disposed at one end of the extension rod 701 .

[0032] Preferably, an extension rod 701 is provided on the outside of the infusion clamp 1, and a pipe clamp 702 is provided at one end of the extension rod 701. The pipe clamp 702 facilitates the infusion clamp 1 to be fixed to the infusion rod to prevent the gravity of the infusion clamp 1 from acting on the infusion tube and affecting the infusion. By fixing the infusion clamp 1 on the pipe clamp 702 with the extension rod 701, the position of the infusion clamp 1 can be adjusted according to the usage situation, and a battery for powering the contact switch is provided in the extension rod 701. The extension rod 701 also needs to be provided with a main switch for controlling whether the battery powers the contact switch.

[0033] Working principle: When working, the infusion clamp 1 is fixed on the infusion tube by using the tube clamp 702, and the clamp handle on the infusion clamp 1 is pressed to open the infusion clamp 1, and the infusion tube is inserted into the infusion clamp 1, and the infusion clamp 1 is placed close to the infusion tube at one end of the infusion bottle. Since there is liquid flowing in the infusion tube, the infusion tube is in a saturated state. At this time, the infusion tube will move toward the inside of the infusion clamp 1 against the contact ball 505, and the infusion ball squeezes the elastic telescopic rod 501 through the column 503 and the movable plate 502, and the movable plate 502 moves while driving the trigger rod. 504 is separated from the contact switch 6, and the main switch on the extension rod 701 is turned on to energize the contact switch 6. When the liquid in the infusion bottle flows out, the gas in the infusion bottle will enter the top of the infusion tube. At this time, the infusion tube will gradually flatten, and the abutment force of the infusion tube on the contact ball 505 will decrease. At this time, the elastic telescopic rod 501 slowly recovers its force, which can drive the moving plate 502 and the contact ball 505 to approach the infusion tube until the trigger rod 504 on the moving plate 502 contacts the contact switch 6. At this time, the contact switch 6 controls the alarm 40 2. The warning light 401 and the electromagnet 304 work. The alarm 402 and the warning light 401 work to remind the medical staff. The electromagnet 304 is energized and has magnetism, which can magnetically attract the magnetic plate 302 in the fixed frame 2, so that the magnetic plate 302 drives the squeezing block 303 to squeeze the infusion tube through the moving rod 301 to prevent the flow of substances in the infusion tube. When the infusion bottle is replaced, the main switch on the extension rod 701 is turned off to cut off the power of the contact switch 6. At this time, the contact switch 6 cannot supply power to the electromagnet 304. , the electromagnet 304 loses its magnetism and continues to attract the magnetic plate 302. At this time, the spring 305 has a restoring force, and the squeezing block 303 can be driven to reset through the magnetic plate 302 and the moving rod. At this time, the negative pressure bag on the infusion tube is squeezed so that the liquid in the infusion bottle can quickly enter the infusion tube and flow. At this time, the infusion tube squeezes the contact ball 505 again to move, so that the trigger rod 504 is separated from the contact switch. At this time, the main switch on the extension rod 702 is started again to energize the contact switch, and it can work when it is squeezed by the trigger rod 504 again.

[0034] It should be noted that the electrical equipment involved in this application can be powered by batteries or external power supply.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
