Abstract
An ultrasonic probe with a pressure regulating device comprises the ultrasonic probe (1) with an upper shell body (7). The ultrasonic probe (1) is provided with an ultrasonic coupling agent container. The ultrasonic probe with the pressure regulating device is characterized in that an air sac (4) with an air sac connector (5) is provided, the ultrasonic coupling agent container is connected with an air sac connecting device (6) which is communicated with the ultrasonic coupling agent container, and the air sac connector (5) is communicated with the air sac connecting device (6).

Description
One, technical field
This utility model relates to a kind of ultrasound probe, is specially a kind of ultrasound probe that regulator is arranged, to realize regulating the ultrasound probe internal pressure automatically in proper range according to the variation of ultrasound probe internal pressure.
Two, background technology
At present, known ultrasound probe is not provided with regulator.Ultrasound probe in the course of the work, internal components can produce heat, causes embedding in the inner ultrasonic coupling agent expanded by heating of ultrasound probe, makes the ultrasound probe internal pressure increase.When this increased pressure can not be born in the cabinet of ultrasound probe and cabinet junction, can make the cabinet of ultrasound probe or shell junction occur breaking.Cause embedding to be overflowed from rent, influence the follow-up use of ultrasound probe in the inner ultrasonic coupling agent of ultrasound probe.
Three, utility model content
The purpose of this utility model is the deficiency that overcomes prior art, designs a kind of can the variation according to the ultrasound probe internal pressure, regulates the ultrasound probe that regulator arranged of ultrasound probe internal pressure in proper range automatically.
The basic ideas of this utility model are: measuring and calculating ultrasonic coupling agent thermal coefficient of expansion is as a calculating parameter.Measure ultrasound probe when extreme environment (maximum operation (service) temperature of correlation standard) descends operate as normal, the ascensional range of probe internal temperature.Multiply by calculating parameter with the ascensional range of probe internal temperature and obtain ultrasound probe inner change in volume amplitude of operate as normal time probe under extreme environment.With the dischargeable capacity of this change in volume amplitude as regulator (air bag).According to this dischargeable capacity with reference to certain volume surplus with being connected of ultrasound probe, make the decompression air bag.Air bag is connected with ultrasound probe, the ultrasound probe pressure inside is changed regulate.
The thermal coefficient of expansion of A, ultrasonic coupling agent is α, according to the computing formula of thermal coefficient of expansion:
In the formula: α-be thermal coefficient of expansion; Δ V-is a volume change; V-is an initial volume; Δ T-is a temperature variation.Can obtain ultrasonic coupling agent change in volume during operate as normal under the extreme temperature environment through calculating.
B, the decompression air bag that is designed consider that the inner air of air bag can not discharge fully when connecting, can consider 10% volume more than needed for air bag, so the volume of air bag is:
V
Q＝110％V
1
C, the air bag internal gas discharged as far as possible after, air bag is connected with ultrasound probe, fixes the shell of driving fit ultrasound probe.
The concrete technical scheme that this utility model adopts is: a kind of ultrasound probe that regulator is arranged; Comprise the ultrasound probe of being with upper shell; Be provided with the ultrasonic coupling agent container in the ultrasound probe; It is characterized in that: be provided with the air bag of band air bag union joint, be connected with the air bag connecting device that is communicated with the ultrasonic coupling agent container on the ultrasonic coupling agent container, the air bag union joint is communicated with the air bag connecting device.
Air bag constitutes regulator.
Operation principle is following:
Under initial temperature, when ultrasound probe is not started working.The air that air bag is inner is owing to be discharged from when being connected and installed, and air bag is in shrivelled state;
When ambient temperature raises, or after ultrasound probe started working and produce heat, ultrasonic coupling agent was heated and begins to expand, and the inner ultrasonic coupling agent volumetric expansion of ultrasound probe this moment enters into air bag.Ultrasonic coupling agent filling after air bag is inflated.The pressure of the expansible volume in back of having avoided being heated to ultrasound probe shell (upper shell of doing like plastics) and damaging property of shell junction.
When ambient temperature reduces, or after ultrasound probe quit work, along with scattering and disappearing of heat, the ultrasonic coupling agent volume began to shrink, and the air bag inner couplant is got back in the ultrasound probe.
Air bag also can be done equivalent substitution with capillary tube:
Substitute air bag with a capillary, in certain temperature range, also can play the effect of regulating the ultrasound probe internal pressure.Direct and the inner UNICOM of probe of capillary tube.When ultrasound probe was not worked, external pressure was greater than the ultrasound wave internal pressure, and the ultrasonic coupling liquid in the ultrasound probe can not flow out because of the effect of gravity.When ultrasound probe is started working, when the probe internal temperature raises,, ultrasonic coupling liquid is pushed capillary tube because the probe internal pressure increases, the expansible volume in back of having avoided being heated produces destructive pressure to ultrasound probe shell and shell junction.
The beneficial effect of this utility model is: avoided embedding when normally using, to cause volumetric expansion from ultrasound probe shell junction to overflow the damage and the pollution that are caused owing to be heated in the inner ultrasonic coupling agent of ultrasound probe.

Among the figure: 1. ultrasound probe; 2. the air bag of shrivelled state; 3. charge into the air bag of ultrasonic coupling agent state; 4, air bag; 5, air bag union joint; 6, air bag connecting device, 7, upper shell.
Five, the specific embodiment
Below in conjunction with accompanying drawing this utility model is done and to be further described.
Like Fig. 1, Fig. 2, Fig. 3 and Fig. 4; A kind of ultrasound probe that regulator is arranged; Comprise the ultrasound probe 1 of being with upper shell 7, be provided with the ultrasonic coupling agent container in the ultrasound probe 1, it is characterized in that: the air bag 4 that is provided with band air bag union joint 5; Be connected with the air bag connecting device 6 that is communicated with the ultrasonic coupling agent container on the ultrasonic coupling agent container, air bag union joint 5 is communicated with air bag connecting device 6.
Before the use, should adjust blood pressure air bag 4 be pinched, discharge the inner air of adjust blood pressure air bag 4 as far as possible after, is connected with air bag connecting device 6, and locks, as shown in Figure 4.Unclamp air bag, it is as shown in Figure 1 that air bag is in shrivelled state.
When ambient temperature raises, or after ultrasound probe 1 started working and produce heat, ultrasonic coupling agent was heated and begins to expand, and enters into adjust blood pressure air bag 4.The expansible volume in back of having avoided being heated produces destructive pressure to ultrasound probe 1 shell and shell junction.
When ambient temperature reduces, or after ultrasound probe 1 quit work, along with scattering and disappearing of heat, the ultrasonic coupling agent volume began to shrink, and adjust blood pressure air bag 1 inner ultrasonic coupling agent is got back to ultrasound probe 1 inside automatically, and adjust blood pressure air bag 1 returns to shrivelled state.
