Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a valve cleaning device with a cleaning position guiding and error-proofing function. Background Art

[0002] An artificial heart valve is an artificial organ that can be implanted in the heart to replace the heart valves. It can enable blood to flow in one direction and has the function of a natural heart valve. When the heart valve disease is severe and the valve separation surgery or repair surgery cannot restore or improve the valve function, an artificial heart valve replacement surgery must be used. Artificial valves are divided into two categories according to the materials used: one is made entirely of artificial materials, called a mechanical valve; the other is made entirely or partially of biological tissue, called a biological valve.

[0003] The biological valve is preserved by being sealed and immersed in a preservation solution containing a bactericide. When in use, the preservation solution on the biological valve needs to be cleaned. The cleaning method is to place the biological valve in a container filled with detergent, and then place the container on a shaker for shaking, so as to achieve the purpose of cleaning. In order to ensure the cleaning effect, it is usually necessary to replace the detergent in the container multiple times and repeat the cleaning action multiple times, which reduces the cleaning efficiency. At the same time, during the shaking process, the valve will be deformed and folded due to the impact of the water flow, which will lead to inadequate cleaning and poor cleaning effect. Therefore, the present application provides a valve cleaning device with a cleaning position guidance and error prevention function to meet the needs. Utility Model Content

[0035] like Figures 1 to 6 As shown, the embodiment of the utility model provides a valve cleaning device with a cleaning position guiding and error-proofing function, including a bearing base 1 and a control host 2 installed on the bearing base 1, a motor box 3 is provided on one side of the control host 2, the motor box 3 is connected to the bearing base 1, a support column 4 is fixedly connected to the top of the motor box 3, a support arm 5 is fixedly connected to one side of the support column 4, an oscillation plate 9 is installed on the support arm 5, a motor is installed inside the motor box 3, a driving shaft 6 connected to the output end of the motor is installed inside the support column 4, a cam 7 is matched and connected to the top of the driving shaft 6, a connecting rod 8 rotatably connected to the cam 7 is installed inside the support arm 5, the connecting rod 8 can reciprocate in the support arm 5, a liquid storage bottle 10, a cleaning cylinder 11, The sewage cup 12, the liquid storage bottle 10 and the cleaning cylinder 11 are connected by a guide tube 13, and the clean cleaning liquid in the liquid storage bottle 10 is introduced into the cleaning cylinder 11 through the guide tube 13, the cleaning cylinder 11 and the sewage cup 12 are connected by a guide hose 14, and the sewage in the cleaning cylinder 11 is introduced into the sewage cup 12 for storage through the guide hose 14. By arranging the liquid storage bottle 10, the cleaning cylinder 11 and the sewage cup 12, during the cleaning process, the sewage cleaned in the cleaning cylinder 11 can be discharged into the sewage cup 12 for storage, and the clean cleaning liquid stored in the liquid storage bottle 10 can be introduced into the cleaning cylinder 11 for a second cleaning. Without stopping the oscillation, the cleaning liquid in the cleaning cylinder 11 can be replaced and the valve can be cleaned multiple times, thereby effectively improving the cleaning efficiency.

[0036] like Figures 3 to 5As shown, the oscillation plate 9 has a stepped structure. The oscillation plate 9 includes three horizontal platforms and is smoothly connected by an inclined plate. A first positioning cylinder 15 is fixedly connected to the top of the upper platform of the oscillation plate 9. The liquid storage bottle 10 is embedded in the first positioning cylinder 15 and is clamped therewith. A locking spring 18 is fixedly connected to the top of the middle platform of the oscillation plate 9. The cleaning cylinder 11 is embedded in the second positioning cylinder 16 and is clamped therewith. A third positioning cylinder 17 is fixedly connected to the top of the lower platform of the oscillation plate 9. The interior of the third positioning cylinder 17 is a hollow structure. The sewage cup 12 is embedded in the hollow structure and is suspended on the oscillation plate 9. By setting the oscillation plate 9, the oscillation plate 9 connected to the connecting rod 8 can make reciprocating motion under the drive of the motor, thereby causing the liquid in the cleaning cylinder 11 to oscillate. The water waves generated by the oscillation clean the valve. At the same time, the structure of the oscillation plate 9 is used to facilitate the liquid in the liquid storage bottle 10 to enter the cleaning cylinder 11 by gravity, and the liquid in the cleaning cylinder 11 enters the sewage cup 12 by gravity, thereby completing the replacement of the cleaning liquid in the cleaning cylinder 11, effectively improving the efficiency of replacing the cleaning liquid, and thereby improving the cleaning efficiency.

[0037] like Figure 1 and Figure 4 As shown, the inner wall of the first positioning cylinder 15 is fixedly connected to a plurality of locking spring pieces 18, the locking spring pieces 18 are curved spring pieces, and the middle part of the locking spring pieces 18 is an arched structure adapted to the locking slide groove 22, the liquid storage bottle 10 is clamped with the first positioning cylinder 15 through the locking spring pieces 18, the outer wall of the first positioning cylinder 15 is fixedly connected to one end of the guide cylinder 13 and is internally connected, the open end surface of the other end of the guide cylinder 13 is an arcuate surface adapted to the surface of the cleaning cylinder 11, the inner wall of the second positioning cylinder 16 is fixedly connected to two groups of locking spring pieces 18 distributed at ninety degrees, the side wall of the second positioning cylinder 16 is provided with a second connecting port 21, and one end of the guide hose 14 is embedded in the second connecting port 21 is sealed and connected to the second positioning cylinder 16. An aeration head 20 is arranged inside the second positioning cylinder 16. The aeration head 20 is embedded in the oscillation plate 9 and sealed and connected thereto. The aeration head 20 is connected to the control host 2 by wire and is controlled by it. By setting the aeration head 20, the number of bubbles in the cleaning liquid is increased, and the impact generated by the bubble rupture is used to clean the preservation liquid remaining on the valve surface, thereby increasing the cleaning effect. The bottom of the third positioning cylinder 17 is a through hole structure, and the sewage cup 12 is suspended on the oscillation plate 9 through the through hole. A first connecting port 19 is opened on the side wall of the third positioning cylinder 17, and the other end of the diversion hose 14 passes through the first connecting port 19 and is sealed and connected to the third positioning cylinder 17.

[0038] like Figure 4As shown, a positioning cylinder 25 is provided in the middle of the second positioning cylinder 16, and the bottom of the positioning cylinder 25 is fixedly connected to the oscillation plate 9, and a plurality of cleaning grooves 26 are opened on the surface of the positioning cylinder 25. By setting the positioning cylinder 25, the top of the positioning cylinder 25 is a conical structure, which is convenient for the valve to be sleeved on the positioning cylinder 25, and the bottom of the positioning cylinder 25 is a conical structure expansion, which can prevent the valve from directly falling and stacking on the top of the oscillation plate 9, resulting in incomplete cleaning. At the same time, since the positioning cylinder 25 has a positioning and guiding effect on the valve, the valve is prevented from being gathered together due to water flow vibration during the cleaning process, resulting in incomplete cleaning. In summary, by setting the positioning cylinder 25, the cleaning effect of the valve can be effectively improved, and the incomplete cleaning of the inner wall of the valve due to the folding of the valve can be avoided. By opening a large number of cleaning grooves 26 on the surface of the positioning cylinder 25, it is made into a hollow structure. During the cleaning process, the cleaning liquid can contact the inner surface of the valve through the cleaning groove 26, so as to avoid the incomplete cleaning caused by the inner surface of the valve being attached to the surface of the positioning cylinder 25, thereby further improving the cleaning effect.

[0039] like Figure 4 and Figure 6 As shown, a locking groove 22 is provided at the bottom of the side wall of the cleaning cylinder 11, and the locking groove 22 rotates 180 degrees around the central axis of the cleaning cylinder 11. A water inlet 23 is provided at the top of the side wall of the cleaning cylinder 11, and a drain outlet 24 is provided at the bottom of the side wall of the cleaning cylinder 11. The water inlet 23 and the drain outlet 24 are rotated 180 degrees, and the water inlet 23 and the drain outlet 24 are vertically aligned with the two ends of the locking groove 22 respectively. By setting the locking groove 22, when the cleaning cylinder 11 is connected to the second positioning cylinder 16, the locking spring pieces 18 distributed in the second positioning cylinder 16 are embedded in the locking groove 22, and the locking spring pieces 18 can rotate relative to the cleaning cylinder 11 in the locking groove 22. However, due to the limited length of the locking groove 22, The relative rotation between the locking spring piece 18 and the cleaning cylinder 11 is restricted, and the cleaning cylinder 11 can only rotate ninety degrees. During the rotation of the cleaning cylinder 11, the water inlet 23 and the port of the guide cylinder 13, and the drain outlet 24 and the second connecting port 21 can be aligned or staggered, so that the cleaning cylinder 11 can quickly switch between the two states. Due to the restriction of the locking spring piece 18, the cleaning cylinder 11 can quickly locate the open and closed state, avoiding the inaccurate positioning of the water inlet 23 and the guide cylinder 13, and the drain outlet 24 and the second connecting port 21, thereby achieving the purpose of replacing the internal cleaning liquid of the cleaning cylinder 11, and the cleaning liquid replacement operation is performed without stopping the oscillation, effectively improving the cleaning efficiency.

[0040] The working principle provided by the utility model is that during use, the operator can clamp the valve with tweezers and put it into the cleaning cylinder 11 filled with cleaning liquid, and put the valve on the positioning cylinder 25. The expansion part at the bottom of the positioning cylinder 25 can effectively prevent the valve from falling to the bottom and stacking on the oscillation plate 9, and the expansion part at the bottom of the positioning cylinder 25 can expand the valve to increase its contact area with the cleaning liquid, thereby improving the cleaning effect.

[0041] When the valve is placed, the motor in the motor box 3 can be started by controlling the host 2. The output end of the motor drives the support arm 5 to rotate, and the cam 7 on the top of the driving shaft 6 rotates synchronously with the driving shaft 6. Due to the eccentricity of the driving shaft 6, the driving shaft 6 drives the connecting rod 8 to do reciprocating motion when rotating, and then drives the oscillation plate 9 to do reciprocating motion. The oscillation plate 9 causes the liquid in the cleaning cylinder 11 to oscillate during the movement, thereby improving the cleaning effect of the valve. At the same time, during the oscillation process of the cleaning liquid in the cleaning cylinder 11, liquid continuously passes through the cleaning groove 26 to impact and clean the inner surface of the valve, so that the valve is cleaned more thoroughly.

[0042] During the entire cleaning process, the water inlet 23 and the guide tube 13, the drain outlet 24 and the second connecting port 21 are staggered respectively, the side walls of the cleaning tube 11 respectively close the guide tube 13 and the second connecting port 21, the liquid storage bottle 10, the cleaning tube 11 and the sewage cup 12 are not connected to each other. After the first stage of cleaning is completed, the cleaning tube 11 can be rotated to align the water inlet 23 and the guide tube 13, and the drain outlet 24 and the second connecting port 21 respectively. At this time, the liquid storage bottle 10 and the cleaning tube 11, and the cleaning tube 11 and the sewage cup 12 are respectively connected, the cleaning liquid after cleaning in the cleaning tube 11 enters the sewage cup 12, and the clean cleaning liquid in the liquid storage bottle 10 enters the cleaning tube 11, to realize the replacement of the cleaning liquid, and then start the second stage of cleaning. The number of cleaning stages can be selected according to needs or actual conditions.

[0043] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
