Description
Technical field
The present invention relates to the medical apparatus and instruments detection technique, relate in particular to a kind of cardiac valve checkout gear.
Background technology
Cardiac valve is that a class is used increasing medical apparatus and instruments, is mainly used in treating because the patient that the cardiac valve that a variety of causes causes damages.The quality of cardiac valve quality is related to quality of life even the life security of each cardiac valve patients with implantation, so in valvular production link, should be equipped with effective detection method, comes the service behaviour of assess cardiac valve.
At present, still belong to blank for the production of valvular one by one checkout equipment on the line, the checkout equipment that is applied to the sampling observation of laboratory cardiac valve is only arranged.The checkout equipment of existing laboratory cardiac valve sampling observation comprises a plurality of assemblies, structure is very complicated, can't realize the sterile working, adopt this experimental facilities can cause valvular pollution, can't be applied on the cardiac valve production line the one by one detection to the cardiac valve product.Valvular service behaviour is different from the test items such as outward appearance of product, is just can show in certain environment.Simultaneously, even if also main rely on complicated sewn by hand process the today that reaches increasingly in Science and Technology Day, there are many factors that may affect the valve service behaviour in the making of valve, and therefore best detection method is to detect one by one but not inspect by random samples.So demand urgently a kind of guarantee the cardiac valve cleaning for the production of the cardiac valve checkout gear that detects one by one on the line.
Summary of the invention
The object of the invention is to, only limit to the problem of destructive sampling observation for above-mentioned present cardiac valve checkout gear, a kind of cardiac valve checkout gear is proposed, this device can be simulated valvular working environment, testing process is to cardiac valve injury or pollution, effectively realized valvular one by one, mass detects.
For achieving the above object, the technical solution used in the present invention is: a kind of cardiac valve checkout gear comprises the transparent pipeline of peristaltic pump, video acquisition system, cardiac valve anchor clamps, water tank and two section one end closure;
Described two sections transparent pipelines not sealing end form transparent channel by the docking of cardiac valve anchor clamps, described cardiac valve anchor clamps energy clamping cardiac valve, and make cardiac valve and transparent channel coaxial; Be respectively arranged with water inlet and outlet on described two sections transparent pipelines; Described cardiac valve anchor clamps can not produce destruction to cardiac valve product or the middle product that detect, and whole transparent pipeline has preferably sealing after installing, and can not produce the phenomenon of leakage.
Be connected with peristaltic pump by pipeline between described water tank and the water inlet, described outlet is communicated with water tank by pipeline;
Described video acquisition system is towards the sealing end of transparent pipeline.
Further, described peristaltic pump is the peristaltic pump with wriggling tempo adjustment function.
Further, also comprise the cardiac valve QA system, described cardiac valve QA system and video acquisition system electrically connect.
Further, be respectively arranged with Pressure gauge on described two sections transparent pipelines, record two place's fluid pressures.
Further, be provided with pressure regulator valve on the pipeline between described outlet and the water tank, be used for regulating the pressure differential between the transparent pipeline in two ends.
Further, the end near sealing is not provided with water inlet and outlet on described two sections transparent pipelines.
Further, described video acquisition system is photographic head.
The operation principle of cardiac valve checkout gear of the present invention is as follows: at first with product clamping in the middle of cardiac valve product or the cardiac valve in the cardiac valve anchor clamps, guarantee that the cardiac valve that is held is coaxial with the cardiac valve anchor clamps; With two sections transparent pipelines not sealing end dock with the cardiac valve anchor clamps respectively and connect the formation transparent channel, need to prove, valvular installation direction need according to and water (flow) direction determine, guarantee correctly to simulate the situation of cardiac valve in human body.The wriggling rhythm of control peristaltic pump, thus fluid (being generally aseptic simulated body fluid, such as phosphate buffered solution or hepes buffer solution etc.) speed and mobile cycle rate of change in the control transparent channel are controlled valvular folding speed at this point.Simulate valvular high speed, middling speed and the low speed (folding condition of 0-200 folding/min), record valvular duty by video acquisition system, the evaluation index of duty is the uniformity and the opening degree of heart valve leaflet folding, then carry out data analysis by artificial or cardiac valve QA system, thereby pass judgment on the credit rating of valve or the middle product of valve.
Cardiac valve structure of the detecting device of the present invention is simple, reasonable, compact, this device can effectively be simulated valvular working environment by arranging of peristaltic pump, by valvular duty in the video acquisition system record transparent channel, detect valvular working condition.Because this cardiac valve structure of the detecting device is simple, each parts easily cleans, and easily realizes i.e. this testing process of aseptic detection not to cardiac valve injury or pollution, effectively realized valvular one by one, mass detects.Cardiac valve checkout gear of the present invention can in time be found product in the middle of valve product that credit rating is not good or the valve, avoids defective work to dispatch from the factory or flows into subsequent processing, will promote greatly the cardiac valve product quality and enhances productivity.
Description of drawings
Fig. 1 is the structural representation of cardiac valve checkout gear of the present invention.
The specific embodiment
Fig. 1 is the structural representation of cardiac valve checkout gear of the present invention.
The present embodiment discloses a kind of cardiac valve checkout gear, as shown in Figure 1, comprises the transparent pipeline 5 of peristaltic pump 1, video acquisition system 2, cardiac valve anchor clamps 3, water tank 4 and two section one end closure.
