Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a non-contact vital sign sensor. Background Art

[0002] Vital signs are indicators used to judge the severity and criticality of a patient's condition, mainly including heart rate, pulse, blood pressure, respiration, pain, blood oxygen, changes in pupil and corneal reflex, etc. Currently, sensors used to monitor human vital signs generally include piezoelectric ceramic sensors. The working principle of piezoelectric ceramic pressure sensors is: let the working end face of the sensor feel (impact) pressure, the sensor generates an electric charge (or voltage), the test system amplifies this charge (or voltage), and then converts it into physical quantities such as pressure, acceleration, mechanical shock and vibration.

[0003] The existing piezoelectric ceramic sensors used for monitoring vital signs have an external shell that is not easy to disassemble, so the piezoelectric ceramic sensors cannot be quickly taken out. Therefore, a non-contact vital sign sensor is urgently needed. Utility Model Content

[0004] The purpose of the utility model is to provide a non-contact vital signs sensor to solve the problem that the piezoelectric ceramic sensor used for vital signs monitoring proposed in the above-mentioned background technology has an external shell that is not easy to disassemble, so that the piezoelectric ceramic sensor cannot be quickly taken out and the piezoelectric ceramic sensor cannot be simply fixed to the pillow, mattress and other equipment when used in conjunction with it.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a non-contact vital sign sensor, comprising a sealing cover, an assembly structure is arranged on the sealing cover, a mounting structure is arranged on the top of the sealing cover, and the bottom end of the sealing cover is connected to a shell.

[0006] The assembly structure includes a card frame, the inner wall of the card frame is connected to a limiting rod, a limiting groove is provided on the right side of the sealing cover, a locking groove is provided on the right side of the shell, and a baffle is movably provided on the outer wall of the shell, a positioning groove is provided on the top of the shell, and a positioning block is locked inside the positioning groove.

[0007] The mounting structure comprises a support seat, an insert block is engaged on the outer side of the support seat, a Velcro is fixed on the inner wall of the support seat, a protective cover is provided on the outer wall of the insert block, and a Velcro mother tape is connected to the top of the Velcro.

[0008] Preferably, a support frame is provided inside the housing, a piezoelectric ceramic sensor is installed at the end of the support frame, and a collection board is installed at the top of the piezoelectric ceramic sensor.

[0009] Preferably, the number of the engaging grooves and the limiting grooves is two, and the sealing cover is engaged and connected with the housing via the positioning block and the positioning groove.

[0010] Preferably, the limiting rod is snap-connected with the limiting groove, the clamping frame is snap-connected with the clamping groove, and the baffle is movably connected with the housing via a rotating shaft.

[0011] Preferably, the support seat is welded to the top of the sealing cover, and a slot matching the plug block is formed on the outer wall of the support seat.

[0012] Preferably, the protective cover is connected to the support base by means of an insert block and a slot, and the Velcro is fixedly connected to the support base by means of glue.

[0013] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0014] First, the utility model provides a card frame, a limit rod, a limit groove and a locking groove. When the piezoelectric ceramic sensor needs to be taken out, the baffle is pushed to rotate upward through the rotating shaft to separate from the card frame. Then the card frame can be pulled out to the outside. When the card frame is pulled out from the locking groove, the limit rod on the inner wall is driven to be pulled out from the limit groove on the right side of the sealing cover. After it is completely pulled out, the card frame is separated from the sealing cover and the outer shell. At this time, the sealing cover is pulled up to make the positioning block be pulled out from the inner side of the positioning groove, so that the sealing cover is separated from the outer shell, and the piezoelectric ceramic sensor can be easily taken out.

[0015] Second, the utility model provides a protective cover, a support seat, a Velcro tape and a Velcro mother tape. This piezoelectric ceramic sensor can be placed under a pillow or a mattress for use, and can conduct and collect signals by contacting the pillow or the mattress. It is necessary to pull the protective cover toward the rear end so that the plug on the inner wall is pulled out from the slot on the outer wall of the support seat, thereby separating the protective cover from the support seat. After separation, the Velcro mother tape and the Velcro child tape can be torn apart, and the Velcro mother tape can be fixed on the pillow or the mattress. After fixation, the sealing cover and the outer shell can be attached to each other through the Velcro child tape and the Velcro mother tape on the top, thereby fixing the sealing cover and the outer shell to the pillow or the mattress. After fixation, the piezoelectric ceramic sensor and the collection board can be used to collect human vital signs. BRIEF DESCRIPTION OF THE DRAWINGS
