Abstract
A kind of assay device testing biologically-derived membrane material burst pressure, installs tube head, pressure detector, water pump and signal output apparatus including biologically-derived film.Biologically-derived film is installed tube head and is included a check valve, one section of flexible pipe, one section of hard plastic tube and two larynx hoops, the import of check valve is connected with the outlet of pressure detector by pipeline, the outlet of check valve and one end of flexible pipe are fixedly linked and tighten sealing by a larynx hoop, and one section of hard plastic tube is nested in the other end of flexible pipe and tightens sealing with another larynx hoop after being coated with biologically-derived membrane material to be measured at its mouth of pipe.The assay device of the present invention is simple to operate, can test the burst pressure of biologically-derived membrane material accurately and effectively.
Description
Technical field
The present invention relates to Mechanics Performance Testing device, particularly relate to a kind of examination testing biologically-derived membrane material burst pressure
Experiment device.
Background technology
Biologically-derived membrane material the most gradually manifests the application prospect that it is powerful, and at medical field, biomembrane has relatively
Good mechanical property and outstanding biocompatibility, so being applied to clinic, such as cerebral dura mater prothesis, blood vessel is repaiied
Multiple art etc..Additionally due to the extensive application that overlay film frame is in aneurysmal disease, biologically-derived film is also considered as blood
The good selection of pipe holder overlay film.The increase used along with biologically-derived film, the mechanical property of biologically-derived film is especially
It is the most closely-related burst pressure, becomes important Consideration.But it is biologically-derived to lack a kind of test at present
The simple and effective assay device of film burst pressure.
Summary of the invention
The purpose of the present invention, it is simply that in order to solve the problems referred to above, it is provided that a kind of biologically-derived membrane material of novel test
The assay device of burst pressure.
In order to achieve the above object, present invention employs techniques below scheme: a kind of biologically-derived film of novel test
The assay device of material demolition pressure, installs tube head, pressure detector, water pump and signal output including biologically-derived film
Device, water delivery side of pump is connected with the import of pressure detector by pipeline, and pipeline is passed through in the outlet of pressure detector
The import installing tube head with biologically-derived film is connected, and pressure detector is also connected with signal output apparatus communication.
Described biologically-derived film is installed tube head and is included a check valve, one section of flexible pipe, one section of hard plastic tube and two larynxs
Hoop, the import of check valve is connected with the outlet of pressure detector by pipeline, the outlet of check valve and one end of flexible pipe
Being fixedly linked and tighten sealing by a larynx hoop, one section of hard plastic tube is used at its mouth of pipe biologically-derived film to be measured
It is nested in the other end of flexible pipe and tightens sealing with another larynx hoop after material cladding.
The external diameter of described hard plastic tube is equal to the internal diameter of flexible pipe.
The invention has the beneficial effects as follows:
1, the material that assay device is used is all that laboratory is easy to get material, it is thus achieved that approach is convenient, thus easily makes
Whole device is promoted the use of.
2, assembly of the invention assembles simple, and detection method is simple, and pressure data is directly obtained by pressure detector
, the numerical value of gained is the most credible.
3, the assay device of the present invention is simple to operate, can test the burst pressure of biologically-derived membrane material accurately and effectively.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of apparatus of the present invention;
Fig. 2 is the structural representation that the biologically-derived film in the present invention installs tube head.
Detailed description of the invention
Seeing Fig. 1, Fig. 2, the assay device testing biologically-derived membrane material burst pressure of the present invention, including biology
Derivative film installs tube head 1, pressure detector 2, water pump 3 and signal output apparatus 4, and water delivery side of pump is by pipe
Road is connected with the import of pressure detector, and the outlet of pressure detector installs tube head by pipeline with biologically-derived film
Import is connected, and pressure detector is also connected with signal output apparatus communication.
Seeing figure Fig. 2, the biologically-derived film in the present invention is installed tube head 1 and is included 11, one section of flexible pipe of a check valve
12, one section of hard plastic tube 13 and two larynx hoops 14, the import of check valve is by the outlet of pipeline with pressure detector
Being connected, the outlet of check valve and one end of flexible pipe are fixedly linked and tighten sealing by a larynx hoop, one section of duroplasts
Pipe is nested in the other end of flexible pipe and uses another larynx after being coated with biologically-derived membrane material to be measured at its mouth of pipe
Sealing tightened by hoop.Wherein, the external diameter of hard plastic tube is equal to the internal diameter of flexible pipe.
Use the present invention assay device test method can accompanying drawings as follows: when non-encapsulation film to be measured,
Being opened by water pump 3, make pump working, pump water enters pipe, makes whole flexible pipe 12 stop water pump after being in the state of filling
Work.Then film 5 to be measured is coated on hard plastic tube 13 port, is nested in silica gel hose, tighten larynx hoop 14,
Without leaking gap before guarantee.Open water pump 3 and pressure detector 2 again, signal output apparatus 4 is observed institute
The pressure data collected.When force value is gradually increasing, occurring rapid drawdown after reaching a bit, the biggest stock current are from film
Upper outflow, the peak value occurred during record data rapid drawdown, can be used as testing the burst pressure value of film.
