Abstract
The invention relates to a pressure reactivity detection device of double-balloon catheters. The pressure reactivity detection device comprises a sealed container which can be opened, wherein the wall of the container is provided with three or more small holes communicated with the inside and outside of the container. The pressure reactivity detection device further comprises an air inlet pressing port and a deflation valve which are used for detecting pressure reactivity of the double-balloon catheters. The pressure reactivity detection device is used for detecting pressure reactivity of one or more double-balloon catheters, and the pressure reactivity detection device can be used for detecting quality of the double-balloon catheters like diaphragm function detection tubes by replacing a traditional balloon blasting method.
Description
(1) technical field
The present invention relates to the particularly stress reaction checkout gear of diaphragmatic function detector tube of double balloon catheter.
(2) background technology
In diaphragmatic function detector tube, there are two tube chambers, connect respectively two air bags that are placed in harmonization of the stomach esophagus and carry out induction pressure.The index of reflection diaphragmatic function is to press across diaphram, and it is the poor of stomach pressure and Esophageal Pressure.To accurately reflect that first diaphragmatic function must ensure that two air bags used have the unobstructed of good and consistent stress reaction and tube chamber.Because the gastric pouch of diaphragm muscle function detection catheter is positioned under esophagus electrode, esophagus electrode may be oppressed the tube chamber that connects gastric pouch, build-up of pressure Low Response.For a long time, measuring is sacculus blasting procedure with the stress reaction of balloon catheter, the capsule pipe that will survey is put into a large sacculus, by improving pressure to inflated, then its increase is broken, and the pressure that records capsule pipe changes.This method is loaded down with trivial details, and capsule guard system of every survey all will seal, then explosion.Particularly general sacculus elasticity is large, even inflation in a large number, the pressure of sacculus and capsule guard system also can only be elevated to tens centimeter water columns, can not reach the required scope that capsule guard system stress reaction detects.We this with double balloon catheter particularly the stress reaction checkout gear of diaphragmatic function detector tube can replace traditional sacculus blasting procedure, and can detect the capsule guard system of many diaphragmatic function detector tubes, and can Reusability simultaneously.
(3) summary of the invention
Be that of providing at present not can be used for detecting the device of diaphragmatic function detector tube can detect many capsule Guan Bingneng simultaneously and makes container inner pressure rise to the device of 100cmH20, be used for detecting the reactivity that capsule guard system changes pressure.Device of the present invention comprises a container with cover and seal, and it is suitable that capacity does not make capsule pipe be deformed into energy holding conduit.Container side is provided with three or above aperture connection container inside and the external world.In addition, chamber wall still has two macropores, connects respectively gas injection pressue device and vent valve.This beneficial effect of the invention is to put into after the container of sealing when diaphragm muscle function detection catheter, gastric pouch pipe and the joint of oesophageal pouches pipe are connected respectively to the inner of aperture, the capsule pipe of putting into again in addition a standard in container is as with reference to capsule pipe, and connects the inner of aperture.Then the outer end of three apertures respectively Bonding pressure sensor connects amplifier, and signal record is shown on computer.When the rapid gas injection of the air inlet of hermetic container pressurization is reached to 100cmH20, vent valve throws open.At this moment the rapid vanishing of container inner pressure.Observe pressure reduction and back to zero time that two capsule guard systems are surveyed.
(4) brief description of the drawings
Below in conjunction with Fig. 1, the stress reaction checkout gear with double balloon catheter is described further.
Fig. 1 is the present invention: with the stress reaction checkout gear figure of double balloon catheter.Zuo Tu is the outside drawing after device sealing, the longitudinal sectional drawing that right figure is device.
In figure, on 1-3. hermetic container wall, be communicated with three apertures of inside and outside; 4. on hermetic container wall, connect the macropore of air pump and container; 5. the vent valve on hermetic container wall; 6. container cover; 7. container body; 8. with reference to air bag joint; 9. the joint communicating with oesophageal pouches with double balloon catheter; 10. the joint communicating with gastric pouch with double balloon catheter.
(5) detailed description of the invention
Open container cover 6, two band air bags, (air bag is for detection of Esophageal Pressure, another balloon detection stomach is pressed) diaphragmatic function detector tube insert in container 7, the joint communicating with oesophageal pouches 9 is connected to the inner of upper aperture 1, the joint communicating with gastric pouch 10 is connected to the inner of upper aperture 2, be connected to the inner of aperture 3 with reference to capsule pipe joint 8, then covered container lid 6.The outer end of aperture 1,2,3 is connected with pressure transducer respectively.By connecting the macropore 4 gas injections pressurizations of air pump on hermetic container wall until when 100cmH20, the flap on vent valve 5 throws open, at this moment can be recorded to the pressure curve then declining suddenly that raises.If three pressure signal lines can overlap, qualified, otherwise, for defective.On the basis of above-mentioned detailed description of the invention, if additionally increase the aperture inside and outside connection container on chamber wall, the conduit quantity can corresponding increase simultaneously detecting.
Claims (2)
1. the stress reaction checkout gear with double balloon catheter.Comprise that can be born a 150cmH
2o is with the hermetic container of upward pressure, and is contained in air inlet pressurization on chamber wall mouthful and vent valve, and several inside and outside apertures of connection container.It is characterized in that having on hermetic container wall an air inlet pressurization mouthful and a vent valve, and aperture inside and outside two or more connection container, hermetic container can Quick-pressing and blood pressure lowering.
2. the stress reaction checkout gear with double balloon catheter according to claim 1, is characterized in that described device can be used for detecting the stress reaction of two accompanying air bags of one or more band double balloon catheter, particularly diaphragmatic function detector tube.
