Description

Technical Field

[0001] This utility model relates to the field of heart valve technology, and in particular to a heart valve incubation and sterilization irrigation device. Background Technology

[0002] Artificial bio-heart valves require a change of sterile packaging bottles to be loaded into during the incubation process. The incubation and sterilization process is then completed using a solution filling step within the sterile packaging bottle. Currently, both incubation and sterilization filling are done manually, i.e., the liquid is poured into a glass beaker and then from the beaker into the sterile packaging bottle. Figure 1 As shown, the disadvantages of this operation method are: cumbersome operation, easy contamination during solution turnover, easy spillage onto the outside of the bottle during filling (residual liquid on the bottle can cause crystallization and yellowing, affecting the appearance and requiring cleaning and removal), and inability to achieve quantitative filling (small filling volume may result in incomplete product immersion, leading to the risk of incomplete incubation and sterilization). After the product has completed incubation, the liquid in the packaging bottle needs to be poured out, and the residual liquid on the valve surface needs to be controlled to a certain extent. This operation process is prone to excessive liquid residue, affecting subsequent sterilization. The solution is easy to stick to the outside of the packaging bottle during the pouring process, requiring cleaning and removal. It is inconvenient to use and difficult to operate. Utility Model Content

[0003] This invention addresses the problems in the existing technology by providing a heart valve incubation and sterilization filling device with a novel structure. It realizes standardized operation of quantitative solution filling, controls and warns of solution residue from the previous process during solution replacement, replaces the tediousness of manual operation, avoids contamination during solution turnover, and improves the efficiency of solution filling, evaporation, and cleaning.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model provides a heart valve incubation and sterilization infusion device, which includes a liquid recovery and suction mechanism, an infusion mechanism, a vacuum generator, and a support base. A lifting plate is movably mounted on the support base. One end of the lifting plate has a liquid suction station, and the other end has an infusion station. A positioning base with a bottle positioning groove is also provided on the support base. The vacuum generator, in conjunction with the liquid recovery and suction mechanism, is used to suction the solution from the packaging bottle, separating the product from the solution. The liquid suction station is used to position the packaging bottle from which the solution needs to be suctioned. The vacuum generator, in conjunction with the infusion mechanism, is used to quantitatively infuse the solution into the packaging bottle. The infusion station is used to position the packaging bottle from which the solution needs to be infused.

[0006] The liquid recovery and suction mechanism includes a liquid recovery container, a suction pipe, and a first vacuum pipe. The two ends of the first vacuum pipe are respectively connected to the first output end of the vacuum generator and the liquid recovery container. One end of the suction pipe is connected to the liquid recovery container, and the other end of the suction pipe is provided with a liquid suction check valve and a liquid suction sealing assembly. The liquid suction sealing assembly is used to seal the packaging bottle to be suctioned.

[0007] The liquid-absorbing sealing assembly includes a liquid-absorbing sealing gasket and a liquid-absorbing tube. The liquid-absorbing tube is disposed through the liquid-absorbing sealing gasket, the lower end of the liquid-absorbing tube is used to extend into the packaging bottle, and the upper end of the liquid-absorbing tube is connected to the other end of the liquid-absorbing pipe.

[0008] The filling mechanism includes a filling container, a filling pipe, and a second vacuum pipe. One end of the second vacuum pipe is connected to the second output end of the vacuum generator, and the other end of the second vacuum pipe is connected to the packaging bottle to be filled. The two ends of the filling pipe are respectively connected to the filling container and the packaging bottle to be filled. One end of the filling pipe is connected to the liquid outlet of the filling container, and the other end of the filling pipe is provided with a one-way filling valve and a filling sealing assembly. The filling sealing assembly is used to seal the packaging bottle to be filled.

[0009] The liquid filling and sealing assembly includes a liquid filling and sealing gasket. The other end of the liquid filling pipe passes through the liquid filling and sealing gasket and extends into the packaging bottle to be filled with liquid. The other end of the second vacuum pipe passes through the liquid filling and sealing gasket and extends into the packaging bottle to be filled with liquid.

[0015] The beneficial effects of this utility model are:

[0016] This utility model features a novel structure. During operation, the bottle containing the solution to be aspirated is placed in the positioning slot of the positioning base. After opening the bottle cap, the vacuum generator is activated. Through the action of the liquid recovery mechanism, a negative pressure is created, causing residual liquid in the bottle to be aspirated to be absorbed into the liquid recovery mechanism. After liquid recovery is complete, the vacuum generator is turned off. When it is necessary to fill the bottle with solution, the vacuum generator is activated again, creating a negative pressure inside the bottle to be filled, allowing the solution to be poured into the bottle. After filling, the bottle cap is tightened to complete the operation. With the above setup, this utility model achieves standardized operation for quantitative solution filling; it controls and provides early warning of residual solution from the previous process during solution replacement, replacing the tediousness of manual operation, avoiding contamination during solution turnover, and improving the efficiency of solution filling, evaporation, and cleaning.

[0027] like Figures 2 to 4As shown, a heart valve incubation and sterilization infusion device includes a liquid collection and suction mechanism 100, an infusion mechanism 200, a vacuum generator 300, and a support base 400. A lifting plate 1 is movably mounted on the support base 400. One end of the lifting plate 1 has a liquid suction station 2, and the other end has a liquid infusion station 3. A positioning base 4 is also mounted on the support base 400, and a bottle positioning groove 5 is provided on the positioning base 4. The vacuum generator 300 cooperates with the liquid collection and suction mechanism 100 to fill the contents of the packaging bottle 500. The solution is aspirated to separate the product from the solution. The aspiration station 2 is used to position the packaging bottle 500 to be aspirated. The vacuum generator 300 cooperates with the filling mechanism 200 to quantitatively fill the packaging bottle 500 with the solution. The filling station 3 is used to position the packaging bottle 500 to be filled with the solution. The vacuum generator 300 has a pumping capacity of not less than 10L / minute and a vacuum degree of not less than 0.086Mpa. The lifting plate 1 can rotate relative to the support base 400, which allows the positions of the filling station 3 and the aspiration station 2 to be switched. Specifically, this utility model has a novel structure. During operation, the packaging bottle 500 containing the solution to be drawn is placed in the bottle positioning groove 5 of the positioning base 4 for positioning. After opening the bottle cap, the vacuum generator 300 is activated. Through the action of the liquid recovery and suction mechanism 100, a negative pressure is created in the liquid recovery and suction mechanism 100, causing residual liquid in the packaging bottle 500 to be drawn to be absorbed into the liquid recovery and suction mechanism 100. After the liquid recovery and suction are completed, the vacuum generator 300 is turned off. When it is necessary to fill the packaging bottle 500 with solution, the vacuum generator 300 is activated again, creating a negative pressure inside the packaging bottle 500 to be filled, allowing the solution to be filled into the bottle. After filling, the bottle cap is tightened to complete the operation. Under the above settings, this utility model achieves standardized operation for quantitative solution filling; it achieves control and early warning of residual solution from the previous process during liquid replacement; it replaces the cumbersome nature of manual operation, avoids contamination during solution turnover, and improves the efficiency of solution filling, evaporation, and cleaning.

[0028] In this embodiment, a weight sensor 17 is provided at the bottom of the positioning base 4; the heart valve incubation and sterilization filling device also includes a controller 600, which is electrically connected to the weight sensor 17 and the vacuum generator 300 respectively. The controller 600 is also provided with several control buttons for controlling the switching of different output terminals of the vacuum generator 300; the controller 600 is also provided with a display screen, on which the weight detected by the weight sensor 17 can be displayed, so that the operator can confirm whether the packaging bottle 500 has completed liquid aspiration or filling, that is, determine the residual state of the solution in the packaging bottle 500 to be aspirated and whether the filling volume meets the requirements.

[0029] In this embodiment, the liquid recovery and suction mechanism 100 includes a liquid recovery container 6, a suction tube 11 channel 7, and a first vacuum pipe 8. The two ends of the first vacuum pipe 8 are respectively connected to the first output end of the vacuum generator 300 and the liquid recovery container 6. One end of the suction tube 11 channel 7 is connected to the liquid recovery container 6, and the other end of the suction tube 11 channel 7 is provided with a suction one-way valve 9 and a suction sealing assembly. The suction sealing assembly is used to seal the packaging bottle 500 to which the solution needs to be suctioned. The suction sealing assembly includes a suction sealing gasket 10 and a suction tube 11. The suction tube 11 is disposed through the suction sealing gasket 10. The lower end of the suction tube 11 is used to extend into the packaging bottle 500, and the upper end of the suction tube 11 is connected to the other end of the suction tube 11 channel 7.

[0030] Specifically, under the above configuration, when the liquid recovery and suction mechanism 100 is working, the vacuum generator 300 is activated, creating a negative pressure in the packaging bottle 500 where the solution to be suctioned needs to be drawn. The residual solution in the packaging bottle 500 is then drawn back into the recovery liquid container 6, achieving standardized operation within the packaging bottle 500 container. The liquid suction sealing gasket 10 provides a sealing effect, preventing the solution from falling out and preventing the packaging bottle 500 from being contaminated by external sources.

[0031] In this embodiment, the filling mechanism 200 includes a filling container 12, a filling pipe 13, and a second vacuum pipe 14. One end of the second vacuum pipe 14 is connected to the second output end of the vacuum generator 300, and the other end of the second vacuum pipe 14 is connected to the packaging bottle 500 to be filled. The two ends of the filling pipe 13 are respectively connected to the filling container 12 and the packaging bottle 500 to be filled. One end of the filling pipe 13 is connected to the liquid outlet end of the filling container 12, and the other end of the filling pipe 13 is provided with a filling one-way valve 15 and a filling sealing assembly. The filling sealing assembly is used to seal the packaging bottle 500 to be filled. The filling sealing assembly includes a filling sealing gasket 16. The other end of the filling pipe 13 passes through the filling sealing gasket 16 and extends into the packaging bottle 500 to be filled. The other end of the second vacuum pipe 14 passes through the filling sealing gasket 16 and extends into the packaging bottle 500 to be filled.

[0032] Specifically, under the above settings, when the filling mechanism 200 is working, the vacuum generator 300 is activated, which creates a negative pressure in the packaging bottle 500 that needs to be filled, and the solution in the filling container 12 enters the packaging bottle 500 that needs to be filled through the filling pipe 13. Furthermore, the weight sensor 17 can be used to detect whether the packaging bottle 500 meets the requirements.

[0033] In this embodiment, the positioning base 4 is inclined; wherein, the inclination angle of the positioning base 4 is 1° to 3° relative to the horizontal plane; preferably, the inclination angle of the positioning base 4 is 1°; this is beneficial for the solution in the packaging bottle 500 to be completely absorbed, reducing or even avoiding the situation of solution residue.

[0034] In this embodiment, the positioning base 4 is further provided with a bottle cap placement slot 18. Specifically, this configuration facilitates the placement of bottle caps from the packaging bottle 500, making storage easier and preventing them from falling and causing contamination.

[0035] In this embodiment, a support column 19 is vertically arranged on the support base 400, and a connecting hole 20 is provided in the middle of the lifting strip 1. The support column 19 passes through the connecting hole 20, and the lifting strip 1 can move up and down relative to the support column 19. Furthermore, the outer periphery of the support column 19 is provided with external threads, and the connecting hole 20 is provided with internal threads. The support column 19 is threadedly connected to the connecting hole 20. With the above configuration, rotating the lifting strip 1 can drive it to rise or fall along the support column 19. Example 2

[0036] In Embodiment 2 of this application, the difference from Embodiment 1 is that the bottom wall of the bottle positioning groove 5 is inclined. Specifically, under this setting, its function is similar to that of the positioning base 4 being inclined; that is, the inclination angle of the bottom wall of the bottle positioning groove 5 is 1°~3° relative to the horizontal plane; this is beneficial for the solution in the packaging bottle 500 to be completely absorbed, reducing or even avoiding the situation of solution residue.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
