Coupling agent spraying device suitable for portable foetus ECG monitor

Abstract

The invention provides a coupling agent spraying device suitable for a portable foetus ECG monitor, relates to the technical field of medical apparatuses and instruments, and solves the problems that a spraying hole cannot be shielded through structural improvement, a shielding structure cannot realize extrusion liquid spraying at the same time, and the shielding structure cannot realize rolling prevention of the spraying device at the same time. The invention discloses a coupling agent spraying device suitable for a portable foetus ECG monitor, which comprises a monitor main body, and the monitor main body is of a cylindrical structure. Through the arrangement of a locking rod, firstly, the locking rod is welded on the monitor main body, the locking rod is of an L-shaped rod structure, and the locking rod is elastically clamped with a groove, so that the locking after the auxiliary plate is adjusted can be realized; and secondly, the locking rod is aligned with a plastic telescopic bottle, the bottom end surface of the locking rod is lower than the tail end of the plastic telescopic bottle, and the locking rod form a protection structure of the plastic telescopic bottle, so that the plastic telescopic bottle can be prevented from being extruded by foreign objects when being placed.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and more specifically relates to a coupling agent spraying device suitable for a portable fetal heart rate monitor. Background technique [0002] Fetal heart rate and fetal movement is a routine method to check whether the fetal development is normal. The normal fetal heart rate changes with the environment in the womb. The change of fetal heart rate is a sign of whether the baby is in good condition in the womb. [0003] For example, the application number: CN202010363062.4, the present invention discloses a couplant spraying device suitable for a portable fetal heart rate monitor, which includes a probe assembly, and is characterized in that it includes a couplant spraying assembly. Through the couplant injection hole, the couplant is stored in the cavity surrounded by the outer rod, retaining ring and inner rod, which facilitates the carrying of the couplant; by pushing different inje...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a coupling agent spraying device suitable for portable fetal heart rate monitors to solve the problem that the existing device prevents The dust performance is weak, and the shielding at the spray hole cannot be realized through structural improvement, and the shielding structure cannot simultaneously realize extrusion spraying, and the shielding structure cannot simultaneously realize the anti-rolling of the spraying device; moreover, The existing device cannot realize the blocking of the extrusion liquid spraying structure, and the blocking structure cannot realize the protection of the liquid spraying structure; finally, the problem that dust is easy to enter the socket after the connecting plug of the existing device is pulled out
