Because in the existing transfusion process, most of medical staff or patients need to observe the change of liquid medicine, the situation that the needle can not be pulled out in time after the transfusion is finished due to the fact that nursing is not in place easily occurs, and then the blood of the patients flows back is caused. Devices for automatically observing the condition of liquid medicine exist in the prior art, but the devices usually cannot close the infusion channel in time or the infusion channel is not closed tightly. Based on the defects, the utility model provides an automatic clamping transfusion alarm.

Example 1

As shown in fig. 1-2, the automatic clamping transfusion alarm comprises a body 1, wherein a clamping groove 11 for clamping a transfusion tube 2 is formed in the body 1, and a photoelectric detector 14 for detecting the liquid of the transfusion tube 2 is further arranged on the body 1; the clamping groove 11 and the clamping groove 11 of the existing transfusion alarm can be designed in the same way, and the transfusion tube 2 can be clamped.

The body 1 is provided with a containing groove 13 close to the clamping groove 11, and an opening of the containing groove 13 faces the clamping groove 11 and is communicated with the clamping groove 11; the body 1 is also provided with an infusion blocking structure 3, and after the infusion blocking structure 3 is started, the infusion tube 2 in the clamping groove 11 is pressed into the accommodating groove 13 to block an infusion channel of the infusion tube 2.

More specifically, the photodetector 14 of the present utility model operates as follows: the body 1 of the utility model is also provided with a controller 15, and the controller 15 is electrically connected with the photoelectric detector 14 and the transfusion blocking structure 3; a storage battery 17 is further arranged in the body 1, and the storage battery 17 supplies power for the operation of the controller 15, the photoelectric detector 14 and the infusion blocking structure 3. The storage battery 17 adopts a high-capacity rechargeable lithium battery, so that convenience and safety of use are ensured.

When the liquid medicine is contained in the infusion tube 2, the section of the infusion tube 2 corresponds to the combination of the two cylindrical convex lenses, and the light rays of the photoelectric detector 14 can not only penetrate but also be gathered into one beam. The light change signal of the photoelectric detector 14 passing through the infusion tube 2 is converted into an electric signal, and the electric signal can be used for alarming under the condition that the infusion tube 2 is free of liquid medicine through a control circuit. The controller 15 receives the information fed back by the photodetector 14, and can control the infusion blocking structure 3 to start, and press the infusion tube 2 in the clamping groove 11 into the accommodating groove 13, so that the infusion channel is closed. In practical applications, since the infusion alarm is usually installed at a position spaced apart from the hand of the patient, the controller 15 receives the infusion completion information fed back by the photodetector 14, and controls the infusion blocking structure 3 to start blocking the infusion channel of the infusion tube 2 after a period of 10 s. The control of the operation of the photodetector 14, the infusion blocking structure 3, away from it by the controller 15 in the present utility model is not a claimed point of the present utility model.

The automatic clamping transfusion alarm is characterized in that a clamping groove 11 for clamping a transfusion tube 2 and a photoelectric detector 14 for detecting liquid in the transfusion tube 2 are arranged on a body 1 of the transfusion alarm. In the infusion process, the change of the liquid medicine is detected by the photoelectric detector 14, and whether the infusion is completed is judged. The body 1 is provided with a containing groove 13 near the clamping groove 11, and the opening of the containing groove 13 faces the clamping groove 11 and is communicated with the clamping groove 11; the body 1 is also provided with an infusion blocking structure 3, and after the infusion blocking structure 3 is started, the infusion tube 2 in the clamping groove 11 is pressed into the accommodating groove 13 to block the infusion channel of the infusion tube 2. When the transfusion is completed, the transfusion blocking structure 3 is started after receiving the transfusion completion information, and the transfusion tube 2 is pressed into the accommodating groove 13, so that the transfusion channel is closed, the blood reflux of a patient is avoided, and the damage to the body of the patient is avoided. In general, the infusion alarm is compact in structure, can automatically detect the state of liquid medicine in the infusion process, closes the infusion channel after the infusion is completed, and can ensure the safety of the infusion.

Further, the infusion blocking structure 3 comprises a driving structure and a blocking hammer 31, the driving structure is arranged on the body 1, the blocking hammer 31 is arranged at the output end of the driving structure, and the shape of the blocking hammer 31 is matched with the shape of the accommodating groove 13; the blocking hammer 31 may be a sphere, and the cambered surface of the sphere presses the infusion tube 2, so that the infusion tube 2 is prevented from being damaged.

After the driving structure is started, the blocking hammer 31 is driven to move, so that the infusion tube 2 in the clamping groove 11 is pressed into the accommodating groove 13.

Still further, the drive structure is a push rod motor 32.

In practical applications, the blocking hammer 31 has a size slightly smaller than the size of the receiving recess 13, so that the blocking hammer 31 can press the infusion tube 2 into the receiving recess 13. The push rod motor 32 is fixed on the body 1, the push rod motor 32 is started by receiving a signal of the controller 15, and the blocking hammer 31 is driven by the push rod to move so as to press the infusion tube 2 into the accommodating groove 13.

In a more preferred embodiment, the body 1 is provided with an LED lamp 12, and the LED lamp 12 is electrically connected to the battery 17. The LED lamp 12 can play a role of a night lamp, so that a patient can know the condition of the infusion bottle under the condition of poor light.

Further, a rounded corner 16 is provided at the connection between the accommodating groove 13 and the clamping groove 11. The round corners 16 can reduce friction between the infusion tube 2 and the accommodating groove 13, and the accommodating groove 13 is arranged to damage the infusion tube 2.

Example 2

As shown in fig. 3, this embodiment only describes the differences from embodiment 1, and the remaining technical features are the same as those of the above-described embodiment. In this embodiment, the driving structure includes a thumb motor 33 and a connecting rod 34, the connecting rod 34 is rotatably connected with the body 1, and the thumb motor 33 is fixed on the body 1; one end of the connecting rod 34 is fixedly connected with the output end of the thumb motor 33, and the other end of the connecting rod 34 is connected with the blocking hammer 31; the thumb motor 33 drives the blocking hammer 31 to move by driving the connecting rod 34 to move.

In this embodiment, the structure of the thumb motor 33 and the connecting rod 34 is used to drive the blocking hammer 31 to move, so that the volume of the alarm can be saved, and the whole infusion alarm is more compact in structure.

Example 3

As shown in fig. 4, this embodiment only describes the differences from embodiment 1, and the remaining technical features are the same as those of the above-described embodiment. In this embodiment, the driving structure includes a connection post 37 and a spring 35, one end of the spring 35 is fixed on the body 1, the other end is fixedly connected with the connection post 37, one end of the connection post 37 away from the spring 35 is connected with the blocking hammer 31, and a magnetic induction coil 36 is wound on the connection post 37;

the magnet 131 is embedded in the accommodating groove 13, and after the magnetic induction coil 36 is energized, a magnetic pole opposite to the magnet 131 is generated at one end of the connecting post 37, which is close to the accommodating groove 13, so that the magnet 131 can suck the blocking hammer 31 into the accommodating groove 13.

The working principle of the driving structure is as follows: in a normal state, the spring 35 is in a natural telescopic state, and the magnetic induction coil 36 is not energized. When the infusion channel needs to be blocked, the storage battery 17 energizes the magnetic induction coil 36, and magnetic poles are formed at the two ends of the connecting column 37. The magnet 131 attracts the connection post 37, causing the connection post 37 to move. The connecting column 37 drives the blocking hammer 31 to move, so that the blocking hammer 31 can squeeze the infusion tube 2 and press the infusion tube 2 into the accommodating groove 13, thereby achieving the purpose of blocking the infusion channel, and the spring 35 is in a stretched state at the moment. When the transfusion is needed, the power supply of the magnetic induction coil 36 is disconnected, the two ends of the connecting column 37 have no magnetic poles, the spring 35 pulls the connecting column 37 back to the original position, and at the moment, the blocking hammer 31 returns to the original position and does not squeeze the transfusion tube 2. The driving structure of the embodiment has lower production cost and small occupied space, and can effectively save the volume of the transfusion alarm.
