Abstract
The utility model provides a kind of vertical erecting bed of artificial heart valve film properties test, including a vertical valve seat, a hollow cavity is offered on the valve seat, prosthetic heart valve assemblies are installed in the cavity, the side of the valve seat offers a fluid inlet, fluid issuing is offered on the opposite side of the valve seat, the valve assemblies include a valve cylinder being placed in cavity, and it is placed in the heart valve prosthesis of valve cylinder bottom, fluid flows through opening and closing campaign of the prosthetic heart valve assemblies finally by the fluid issuing outflow driving heart valve prosthesis progress vertical direction from the fluid inlet.Vertical erecting bed can directly carry out the replacing of artificial valve in the case where being not excluded for solution, meanwhile, transparent observation post can directly be detected in detection process, convenient and swift.
Description
Technical field
The utility model belongs to medical detecting Instrument technical field, and in particular to a kind of artificial heart valve film properties test is used
Vertical erecting bed.
Background technology
Heart valve disease is one of main angiocardiopathy at present, there is rheumatic, degeneration and congenital etc. a variety of
The cause of disease, and most unique treatment methods of valve disease patient are exactly to carry out artificial Cardiac Valve Replacement.The quality of valve is straight
The safety for being related to patient is connect, therefore the property indices of valve need to be tested and understood.Evaluate and compare mechanical property
Realized mainly by extracorporeal simulating experiment device.Wherein, the testing in vitro of heart valve prosthesis fatigue behaviour is to assess design
Important means, and enter the prerequisite of clinical trial.
Need by erecting bed to install heart valve prosthesis on a testing machine additional when carrying out heart valve prosthesis test, it is existing
Some erecting beds typically use horizontal type, i.e., when test completion needs to change, it is necessary to first arranged the solution in system completely
Remove, heart valve prosthesis could be taken out, it is complex for operation step, it indirectly have impact on observed efficiency.
Utility model content
The utility model provides a kind of vertical erecting bed of artificial heart valve film properties test.
The purpose of this utility model is achieved through the following technical solutions：
The vertical erecting bed of artificial heart valve film properties test, including a vertical valve seat, one is offered on the valve seat
Hollow cavity, prosthetic heart valve assemblies is installed in the cavity, the side of the valve seat offers a fluid inlet, described
Fluid issuing is offered on the opposite side of valve seat, the valve assemblies include a valve cylinder being placed in cavity, and are placed in valve
The heart valve prosthesis of cylinder bottom, fluid flow through prosthetic heart valve assemblies from the fluid inlet and gone out finally by the fluid
Mouth outflow drives the opening and closing campaign of the heart valve prosthesis progress vertical direction.
Preferably, an observation cylinder is provided with above the cavity, the observation cylinder is coaxial with the valve cylinder.
Preferably, the observation cylinder also includes a transparent observation rod, the observation rod be placed in the observation cylinder top and
It is interspersed to be placed in observation cylinder.
Preferably, the observation cylinder is connected by screw with the valve seat, and the observation cylinder and the valve seat junction
It is provided with sealing ring.
The beneficial effects of the utility model are embodied in：Vertical erecting bed can be in the case where not exclusively excluding solution directly
The replacing of artificial valve is carried out, meanwhile, transparent detection post can directly be observed in detection process, convenient and swift.
Brief description of the drawings
Fig. 1：Structural representation of the present utility model.
Embodiment
A kind of vertical erecting bed of artificial heart valve film properties test is specifically described with reference to embodiments, including one stands
The valve seat 1 of formula, a hollow cavity is offered on the valve seat 1, prosthetic heart valve assemblies are installed in the cavity.The valve
The side of seat offers a fluid inlet 14, and fluid issuing 11, the fluid issuing 11 are offered on the opposite side of the valve seat 1
UNICOM vertical with the cavity.The valve assemblies include a valve cylinder 3 being placed in cavity, and are placed in the bottom of valve cylinder 3
Heart valve prosthesis 4, fluid flow through prosthetic heart valve assemblies finally by the fluid issuing 11 from the fluid inlet 14
Outflow, the heart valve prosthesis is driven to carry out the opening and closing campaign of vertical direction.
An observation cylinder 2 is provided with above the cavity, the observation cylinder 2 is coaxial with the valve cylinder 3.In order to preferably see
Examine, the observation cylinder 2 also includes a transparent observation rod 21, and the observation rod 21 is placed in the top of observation cylinder 2 and interted and puts
In in observation cylinder 2.When heart valve prosthesis is being moved, operating personnel can carry out observing its shape by observing rod 21
State.
The observation cylinder 2 is connected by screw with the valve seat 1, in order to ensure to observe the sealing of cylinder 2 and valve seat 1, institute
State observation cylinder 2 and the junction of valve seat 1 is provided with sealing ring.
Because whole valve seat is three-dimensional, during work in-process cavity body, in order to easy to process, cavity shape in valve seat
Into through hole, i.e., both ends UNICOM is formed on valve seat.End cap is used in the upper ends prosthetic heart valve assemblies of cavity, cavity lower end 13
Sealed.
Prosthetic heart valve assemblies vertical vertical setting in valve seat, when needing to change heart valve prosthesis, without inciting somebody to action
In-house solution excludes completely, directly takes out valve assemblies, is changed.The time is saved, it is efficient and convenient, indirectly
Improve operating efficiency.
The utility model still has a variety of specific embodiments.All institutes formed using equivalent substitution or equivalent transformation
Have technical scheme, all fall within the requires of the utility model protection within the scope of.
