Battery compartment and vital sign monitor

Abstract

The invention provides a battery compartment and a vital sign monitor. The battery compartment comprises a button switch, a rotary knob end, a first end face sealing part, a battery compartment body, a second end face sealing part and a battery compartment housing; the button switch, the rotary knob end and the battery compartment body are connected in sequence; the first end face sealing part sleeves the battery compartment body and is tightly attached to the rotary knob end; an accommodating groove is formed in the battery compartment housing; outer screw threads are arranged on the outer wall at one end of the battery compartment body close to the first end face sealing part; and inner screw threads matched with the outer screw threads are arranged on the inner wall of the accommodating groove at one end of the battery compartment housing close to the second end face sealing part. The screw threads sealing is combined with the end face sealing, so that the battery compartment has the dual waterproof and dustproof functions, the highest sealing and protection level of the battery compartment in emergency conditions is achieved, and power supply for instruments is ensured.

Description

technical field [0001] The invention relates to the field of vital information monitoring, in particular to a battery compartment and a vital sign monitor. Background technique [0002] At present, the protection level design method for instruments mainly relies on sealing rings and grooves as sealing means, but this sealing means is not very practical for small instruments (such as battery compartments of vital signs monitors) that have external dimensions and internal space requirements. The protection level of this sealing means instrument can not reach IP68. In an emergency scenario, the environment of the protective equipment worn by rescuers is relatively harsh. Once the protection level design of the battery compartment of the equipment is unreasonable, the required sealing level cannot be achieved, the waterproof and dustproof effect cannot be achieved, and the equipment cannot be used. The vital signs monitoring instruments of rescuers are useless, and the life saf...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a battery compartment and a vital sign monitor, which are used to solve the requirements of the prior art on external dimensions and internal space by relying on sealing rings and grooves as sealing means. When the small instrument is sealed, the required sealing level cannot be achieved, and the waterproof and dustproof effect cannot be achieved, which makes the instrument unusable and threatens the life safety of rescuers.
