technical field

The utility model relates to the field of medical instrument cable storage, in particular to an automatic shrinking device for medical instrument cables.

Background technique

Hospital departments and wards have all kinds of precision instruments, such as monitors, etc. When these instruments are used, there are many cables connected to them. If they are not protected, the cables may be damaged, broken, and the interface damaged. Moreover, the cables are easy to intertwine and messy, which wastes time to sort out and seriously reduces the work efficiency of medical staff; in this case, some devices are needed to improve work efficiency and cleanliness. At present, cable ties are also used to bundle randomly in clinical practice, which looks messy and inconvenient for maintenance; and cable ties are easy to slide and have a short service life, which affects the arrangement of cables.

Prior art CN206720498U discloses a medical cable fixing device. When the staff presses the rotary switch to start the motor, the motor drives the gear to rotate, the gear drives the rotating shaft to rotate, and the rotating shaft drives the reel to rotate. After the medical cable passes through the fixing groove, the reel The medical cable is coiled at a constant speed, the medical cable is fixed on the reel, and the staff takes the coiled medical cable out of the shaft; the staff presses the extension switch, the electric telescopic rod starts to work, and the electric telescopic rod drives the first The first storage rack, the second storage rack and the third storage rack protrude from the workbench at the same time. The staff stores medical cables according to different specifications. The staff presses the retract switch, and the electric telescopic rod drives the first storage rack and the second storage rack. The storage rack and the third storage rack are retracted into the workbench at the same time to realize the access and shrinkage of medical cables. However, the prior art still has the following problems:

1) In the prior art, the medical cables cannot be retracted automatically after being taken out, and the staff needs to sort them out first, and then use the motor to drive the reels one by one to reel the medical cables at a uniform speed to realize the retraction of the cables, which takes more time , seriously reducing the work efficiency of staff;

2) In the prior art, the storage racks of various medical cables are all driven by the same motor, so that various medical cables can be taken in and out at the same time, and one kind of cable will be loosened after use and then taken out again. Use the next type of cable, and wait until all the cables are used up before taking them back together; in this way, when the cables are used, the irregular scattering of the previously used cables will affect the use of subsequent cables, and it is easy to entangle The phenomenon of knotting makes the use effect greatly reduced;

3) In the prior art, it is necessary to drive the telescopic device through the motor every time the cable is taken and retracted; and it takes time to retract and retract the motor-driven storage rack, and additional noise will be emitted during the process, which is difficult for inspection or treatment. Some patients cause psychological pressure and fear, reducing the patient's sense of experience.
