Abstract
Description
Technical Field
[0001] This utility model relates to the fields of biology and medicine, and more specifically, to a piezoelectric membrane breaking device with a weighted oil needle holding assembly. Background Technology
[0002] The weighted oil needle holder assembly is a crucial component of a piezoelectric membrane rupture device, primarily used for precision operations in medical equipment, laboratory analysis, or industrial applications. Piezoelectric membrane rupture devices are typically used for rupture processes involving liquids or other materials, and the weighted oil needle holder assembly is responsible for providing stable needle support during operation, ensuring the accuracy and consistency of the rupture process.
[0003] Chinese Patent Announcement No. CN118726057A discloses a piezoelectric membrane rupture device that maintains horizontal vibration. This patent is a continuously angled type, ensuring that the operating angles of the piezoelectric element, the master needle holder, and the bending operation needle are consistent. As long as the piezoelectric element is kept horizontal during installation and debugging, the vibration generated by the piezoelectric element can be directly transmitted along the master needle holder, the bending tube, and the auxiliary needle holder to the connected bending operation needle. This ensures that the vibration transmitted from the end of the bending operation needle remains horizontal during vibration, avoiding the vertical motion vector that is always generated in traditional piezoelectric operation. This not only reduces the difficulty of equipment debugging and operation in experiments but also improves embryo safety and survival rate.
[0004] However, the aforementioned patent does not allow for free switching between the micromanipulator and the heavy oil during the process, and there are issues with air and oil leakage. Utility Model Content
[0005] 1. Technical problems to be solved
[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a piezoelectric film breaking instrument heavy oil needle holding assembly. It can achieve the purpose of switching the connection between the micromanipulator connecting pipe and the heavy oil filling pipe and the brake through a switcher. At the same time, it can effectively prevent air leakage in the micromanipulator connecting pipe and liquid leakage in the heavy oil filling pipe, greatly improving the practicality of the device.
[0007] 2. Technical Solution
[0008] To solve the above problems, the present invention adopts the following technical solution.
[0009] A piezoelectric membrane breaking instrument with a heavy oil needle holder assembly includes a controller. A connecting line is fixedly connected to the rear end of the controller. A switcher is fixedly connected to the end of the connecting line away from the controller. A brake is fixedly connected to the end of the switcher away from the connecting line. A micromanipulator connecting tube and a heavy oil filling tube are fixedly connected to the end of the switcher away from the brake, respectively. A syringe is fixedly connected to the end of the heavy oil filling tube away from the switcher. The switcher switches the connection between the micromanipulator connecting tube and the heavy oil filling tube and the brake, effectively preventing air leakage from the micromanipulator connecting tube and liquid leakage from the heavy oil filling tube, greatly improving the practicality of the device.
[0010] Furthermore, the switcher includes a wheel plate, with a connecting pipe port and a refueling pipe port respectively opened at the end of the wheel plate away from the brake. The connecting pipe port and the refueling pipe port are fixedly connected to the connecting pipe of the micromanipulator and the heavy oil refueling pipe, respectively. A brake interface is opened at the lower end of the wheel plate and is fixedly connected to the brake. A rotating hole is opened in the wheel plate, and the connecting pipe port, the refueling pipe port and the brake interface are respectively connected to the rotating hole. The connecting pipe port and the refueling pipe port are respectively connected to the connecting pipe of the micromanipulator and the heavy oil refueling pipe, so that the micromanipulator and the heavy oil refueling are sequentially connected to the brake.
[0011] Furthermore, the switcher also includes a rotating plate, which is rotatably connected to the inner end of the rotating hole. The rotating plate has a through hole in the middle, and the wheel plate has an adjustment groove at the end near the brake, which is connected to the rotating hole. An adjustment rod is slidably connected in the adjustment groove and is fixedly connected to the rotating plate. By applying force to the syringe, the syringe slides along the adjustment groove, thereby causing the rotating plate to rotate and connecting the through hole to the connecting pipe port or the oil filling pipe port, thus achieving the purpose of free switching.
[0012] Furthermore, the switcher also includes a magnetic ring, which is fixedly connected to the inner wall of the through hole on the side away from the brake. Magnetic suction rings are fixedly connected to the inner walls of the connecting pipe port and the refueling pipe port on the side near the rotating plate. When the through hole rotates to connect with the connecting pipe port or the refueling pipe port, the magnetic ring and the corresponding magnetic suction ring attract and fix it in place. This not only aligns the switched through hole with the connecting pipe port or the refueling pipe port, but also provides a sealing effect under the attraction.
[0013] Furthermore, the switcher also includes a sealing ring, which is fixedly connected to the end of the rotating plate near the brake interface. The sealing ring can effectively improve the sealing effect between the through hole and the brake interface, preventing air or liquid leakage.
[0014] Furthermore, the controller is provided with a pair of heat dissipation vents on its outer end, which can dissipate heat from the controller, thereby maintaining the controller's performance and extending its service life.
[0015] 3. Beneficial effects
[0016] Compared with existing technologies, the advantages of this utility model are:
[0017] (1) This solution uses a switcher to switch the connection between the micromanipulator connecting pipe and the heavy oil filling pipe and the brake. At the same time, it can effectively prevent air leakage from the micromanipulator connecting pipe and liquid leakage from the heavy oil filling pipe, greatly improving the practicality of the device.
[0018] (2) In this scheme, the switcher includes a wheel plate. The end of the wheel plate away from the brake is provided with a connecting pipe port and a refueling pipe port, and the connecting pipe port and the refueling pipe port are fixedly connected to the connecting pipe of the micromanipulator and the heavy oil refueling pipe, respectively. The lower end of the wheel plate is provided with a brake interface, and the brake interface is fixedly connected to the brake. A rotating hole is provided inside the wheel plate, and the connecting pipe port, the refueling pipe port and the brake interface are respectively connected to the rotating hole. The connecting pipe port and the refueling pipe port are respectively connected to the connecting pipe of the micromanipulator and the heavy oil refueling pipe, so that the micromanipulator and the heavy oil refueling are connected to the brake in sequence.
[0019] (3) The switcher in this scheme also includes a rotating plate, which is rotatably connected to the inner end of the rotating hole. A through hole is opened in the middle of the rotating plate. An adjustment groove is opened at the end of the wheel plate near the brake, and the adjustment groove is connected to the rotating hole. An adjustment rod is slidably connected in the adjustment groove, and the adjustment rod is fixedly connected to the rotating plate. By applying force to the syringe, the syringe slides along the adjustment groove, thereby causing the rotating plate to rotate and connecting the through hole to the connecting pipe port or the oil filling pipe port, thereby achieving the purpose of free switching.
[0020] (4) The switcher in this scheme also includes a magnetic ring. The magnetic ring is fixedly connected to the inner wall of the through hole away from the brake. The inner wall of the connecting pipe port and the refueling pipe port near the rotating plate is fixedly connected to a magnetic suction ring. When the through hole is rotated to connect with the connecting pipe port or the refueling pipe port, the magnetic ring is attracted and fixed by the corresponding magnetic suction ring. This not only allows the through hole after switching to be aligned with the connecting pipe port or the refueling pipe port, but also provides a sealing effect under the adsorption.
[0021] (5) The switcher in this scheme also includes a sealing ring. The sealing ring is fixedly connected to the end of the rotating plate near the brake interface. The sealing ring can effectively improve the sealing effect between the through hole and the brake interface, preventing air or liquid leakage.
[0022] (6) In this solution, a pair of heat dissipation ports are provided on the outer end of the controller. The heat dissipation ports can dissipate heat from the controller, thereby keeping the controller in good performance and improving its service life. Attached Figure Description

[0031] Example 1:
[0032] Please see Figure 1-3A piezoelectric membrane breaking instrument with heavy oil needle support assembly includes a controller 1. A connecting line 2 is fixedly connected to the rear end of the controller 1. A switcher 3 is fixedly connected to the end of the connecting line 2 away from the controller 1. A brake 4 is fixedly connected to the end of the switcher 3 away from the connecting line 2. A micromanipulator connecting tube 5 and a heavy oil filling tube 6 are fixedly connected to the end of the switcher 3 away from the brake 4, respectively. A syringe 7 is fixedly connected to the end of the heavy oil filling tube 6 away from the switcher 3. The switcher 3 switches the connection between the micromanipulator connecting tube 5 and the heavy oil filling tube 6 and the brake 4, and can effectively prevent air leakage from the micromanipulator connecting tube 5 and liquid leakage from the heavy oil filling tube 6, greatly improving the practicality of the device.
[0033] The switcher 3 includes a wheel plate 31. The end of the wheel plate 31 away from the brake 4 is provided with a connecting pipe port 32 and a refueling pipe port 33, which are respectively fixedly connected to the micromanipulator connecting pipe 5 and the heavy oil refueling pipe 6. The lower end of the wheel plate 31 is provided with a brake interface 34, which is fixedly connected to the brake 4. A rotating hole is provided inside the wheel plate 31, and the connecting pipe port 32, the refueling pipe port 33 and the brake interface 34 are respectively connected to the rotating hole. The connecting pipe port 32 and the refueling pipe port 33 are respectively connected to the micromanipulator connecting pipe 5 and the heavy oil refueling pipe 6, so that the micromanipulator and the heavy oil refueling are sequentially connected to the brake 4.
[0034] The switcher 3 also includes a rotating plate 35, which is rotatably connected to the inner end of the rotating hole. A through hole 36 is provided in the middle of the rotating plate 35. An adjustment groove is provided at the end of the wheel plate 31 near the brake 4, and the adjustment groove is connected to the rotating hole. An adjustment rod 37 is slidably connected in the adjustment groove, and the adjustment rod 37 is fixedly connected to the rotating plate 35. By applying force to the syringe 7, the syringe 7 slides along the adjustment groove, thereby causing the rotating plate 35 to rotate and connecting the through hole 36 to the connecting pipe port 32 or the oil filling pipe port 33, thereby achieving the purpose of free switching.
[0035] The switcher 3 also includes a magnetic ring 38, which is fixedly connected to the inner wall of the through hole 36 away from the brake 4. Magnetic rings 39 are fixedly connected to the inner walls of the connecting pipe port 32 and the refueling pipe port 33 near the rotating plate 35. When the through hole 36 is rotated to connect with the connecting pipe port 32 or the refueling pipe port 33, the magnetic ring 38 and the corresponding magnetic ring 39 attract and fix it in place. This not only allows the switched through hole 36 to align with the connecting pipe port 32 or the refueling pipe port 33, but also provides a sealing effect under the attraction.
[0036] The switcher 3 also includes a sealing ring 310, which is fixedly connected to the end of the rotating plate 35 near the brake interface 34. The sealing ring 310 can effectively improve the sealing effect between the through hole 36 and the brake interface 34, preventing air or liquid leakage.
[0037] The controller 1 has a pair of heat dissipation vents 8 on its outer end. The heat dissipation vents 8 can dissipate heat from the controller 1, thereby keeping the controller 1 in good performance and extending its service life.
[0038] When using it, please refer to Figure 1-3 When it is necessary to switch between gas and liquid, a force is applied to the syringe 7 to make the syringe 7 slide along the adjustment groove, thereby rotating the rotating plate 35 and connecting the through hole 36 with the connecting pipe port 32 or the oil filling pipe port 33, so that the switch can be made freely. Compared with the traditional piezoelectric film breaking instrument heavy oil holding needle assembly, this utility model can realize the purpose of switching the connection between the micromanipulator connecting pipe 5 and the heavy oil filling pipe 6 and the brake 4 through the switcher 3. At the same time, it can effectively prevent air leakage of the micromanipulator connecting pipe 5 and liquid leakage of the heavy oil filling pipe 6, greatly improving the practicality of the device.
