Reading pressure gauge 20 reading.
Specifically, following application method and operating method to above-mentioned closing strength tester, using encapsulant as hemostasis
Illustrated exemplified by material.
Following steps S102-106 can be specifically divided into:
Step S102:Detected materials are applied on the aperture set on the container of the test serum formation, wait pre-
If duration makes its gel, the application area of the detected materials is more than the area in the aperture.
It should be noted that in the present embodiment, detected materials are the encapsulant available for closing aperture or hole, such as
Hemostatic material of painting type etc..In the following description, so that encapsulant is hemostatic material as an example, to the specific mistake of the above method
Journey is illustrated.
When being tested using foregoing closing strength tester the closing intensity of hemostatic material, by such as water to be measured
The hemostatic material of gel is applied on the aperture 402 set on the container 40 of foregoing test serum formation, also, the hemostasis smeared
The application area of material is more than the area in aperture 402, so that the hemostatic material smeared can cover aperture 402.
It should be noted that in the present embodiment, to be measured available for above-mentioned tester can be used for closing aperture or hole
The encapsulant of gap be limited to can painting type encapsulant or the encapsulant of adhesive formula, for example, hydrogel material only
Blood material etc..In the present embodiment, hemostatic material is not limited, it is only necessary to which the hemostatic material adheres to above-mentioned simulation and moved
On property management shape or bourse, and the aperture in animal tubulose or bourse can be sealed.
In the present embodiment, it is not to smear the container 40 that hemostatic material or cohesive stanch bleeding material are formed in test serum
It aerating device 10 can be used to be inflated after on the aperture 402 of upper setting, and need smearing hemostatic material or stickup
The regular hour is waited after hemostatic material, so that the adhesion that hemostatic material forms firm gel layer or hemostatic material is steady
Gu, with the accuracy for the performance test for ensureing hemostatic material;For example, the duration waited can be preset duration 15 minutes.
Step S104:It is inflated by the aerating device, until the gel layer rupture of detected materials formation.
In the present embodiment, by closing strength tester inside be inflated with change the air pressure inside tester come
Influence in hemostasis of the blood in human body in pressure for hemostatic material is simulated, i.e., by constantly pressing or extruding aerating device 10
Tester inside is inflated, to increase the air pressure inside tester.
It should be noted that in the present embodiment, the frequency being inflated by the aerating device is no more than the pressure
The numerical value jumping frequency rate of power table, for example, the frequency of pressing aerated capsule ball is no more than the manometric numerical value jumping frequency rate.Pressure
The numerical value jumping frequency rate of power table is manometric sensitivity, if pressing test serum frequency exceeded it is manometric sensitive
Degree, that is, inflate too fast, then when being likely to result in the gel layer of detected materials formation by bursting, the pressure value shown on pressure gauge is also stopped
Stay in the pressure value that previous instant is measured, i.e., be not detected materials formation gel layer by pressure value during bursting, so as to cause
Test result is inaccurate.
Step S106:The manometric pressure value is recorded as the closing intensity level of the detected materials.
Manometric pressure value is the gel layer for forming detected materials when the gel layer of detected materials formation is by bursting
Closing intensity occurrence, the maximum closing intensity that as detected materials can be born during hemostasis.
Optionally, in the present embodiment, temperature may influence the anthemorrhagic performance of hemostatic material, therefore, in the present embodiment
In, in order to more accurately simulate anthemorrhagic performance of the hemostatic material in real hemostasis, in addition it is also necessary to which test serum is formed
Container 40 and tester are generally held in body temperature.
Specifically, methods described also includes:The closing strength tester is placed in water-bath, to keep the envelope
Strength tester is closed in preset temperature, for example, preset temperature is 37 degree.
It should be noted that in the present embodiment, closing strength tester integrally can be prevented from water-bath protecting
Default temperature is held, or, can also be that bottle,suction is placed in water-bath, the then liquid by being equipped with bottle,suction
The temperature inside tester to be adjusted.
The closing strength tester evaluation that the above-mentioned closing strength tester of the utility model offer is different from the past is stopped blooding
The scheme of the anthemorrhagic performance of material, the mode of blood pressure is replaced using air pressure, the mode of the bleeding of people's in-vivo tissue and seepage is simulated,
More simulate hemostatic material really hemostasis scene in human blood-pressure for the closing intensity of hemostatic material influence, raising
It is used for the accuracy for closing the test of the closing intensity of the encapsulant of aperture or hole in test.
That is, during testing the closing intensity of the encapsulant for closing aperture or hole,
Set on the container for test serum (such as animal tissue) formation that hemostatic material to be measured is applied to simulation human body blood outlet
Aperture on, after gel layer to be formed, be constantly inflated to increase the air pressure inside test serum by aerating device
So that the gel layer of hemostatic material formation to be measured is by bursting, so as to obtain the maximum pressure that hemostatic material to be measured can bear
Value, i.e., the maximum closing intensity that hemostatic material to be measured can bear.That is, replacing the mode of blood pressure, mould using air pressure
Intended the mode of the bleeding of people's in-vivo tissue and seepage, rebuild hemostatic material really hemostasis scene in human blood-pressure for
The influence of the closing intensity of hemostatic material, improves and is testing the closing intensity for the encapsulant for being used to close aperture or hole
The accuracy of test.
Above disclosed is only the utility model preferred embodiment, can not limit the utility model with this certainly
Interest field, therefore equivalent variations made according to the utility model claim still belong to the scope that the utility model is covered.
