Post-embryo transfer nutritional support delivery device

Abstract

This utility model discloses a nutritional support delivery device after embryo transfer, belonging to the technical field of embryo transfer equipment. It includes a timed and quantitative supply mechanism, which delivers internal nutrients at specific time intervals and volumes. This utility model achieves convenient disassembly and precise flow control in one integrated system. Its modular design utilizes a positioning groove on a fixed plate that engages with a built-in spring-loaded round-headed block. During installation, the positioning block of the outer fixed platform of the supply mechanism is pushed into the groove, and the positioning hole aligns with the round-headed block, triggering the spring self-locking to ensure stability and prevent displacement. This also facilitates disassembly, replacement, and cleaning, improving safety. The core flow control relies on a drive motor to rotate a perforated disc. The disc's through-holes periodically align with or offset the leakage holes at the bottom of the storage cylinder, achieving on / off control of the liquid flow. By adjusting the motor speed, the supply interval and single-volume output are precisely adjusted, achieving reliable timed and quantitative release.

Description

Technical Field

[0001] This utility model relates to the field of embryo transfer equipment technology, specifically a nutritional support delivery device after embryo transfer. Background Technology

[0002] Existing nutrient delivery equipment often adopts a fixed structure or a single supply unit, lacking a convenient and reliable modular installation mechanism. This makes the disassembly, component replacement, and thorough cleaning of the entire device inconvenient and time-consuming when multiple nutrient solutions are needed or when cleaning and maintenance are required. In some cases, dead corners are difficult to clean, increasing the risk of contamination and maintenance burden. At the same time, existing technologies for timed and quantitative nutrient solution delivery may rely on more complex valve systems, electronic flow meters, or peristaltic pumps. These methods have problems such as complex structure, high cost, easy wear, easy clogging, or unstable control accuracy at low flow rates. They are difficult to continuously and accurately achieve preset small flow interval release and single discharge control during long-term supply, resulting in poor reliability. Therefore, a nutrient support delivery device after embryo transfer is provided to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a nutritional support delivery device after embryo transfer in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a nutritional support delivery device after embryo transfer, comprising:

[0005] A timed and quantitative supply mechanism is used to deliver internal nutrients at certain time intervals and in certain quantities.

[0006] A fixed support mechanism is provided to fix the nutrition support delivery equipment in a suitable position and to provide a stable fixed position for the timed and quantitative supply mechanism. The fixed support mechanism includes an annular plate, on both sides of which fixed plates are symmetrically fixedly connected. On one side of the inner wall of the fixed plate, a plurality of first positioning grooves and spring grooves are equidistantly formed in groups of two. On another side of the inner wall of the fixed plate, a plurality of second positioning grooves are equidistantly formed. One end of a support spring is fixedly connected to the inner wall of the spring groove, and the other end of the support spring is fixedly connected to a round-headed top block.

[0007] As a further embodiment of this utility model: the timed and quantitative supply mechanism includes a nutrient storage cylinder, a set of leakage holes at the bottom of the nutrient storage cylinder, a drainage funnel fixedly connected below the nutrient storage cylinder, a nutrient delivery pipe fixedly connected to the outlet of the drainage funnel, a drive motor fixedly connected above the upper cover of the nutrient storage cylinder, a feeding slot opened in the upper cover of the nutrient storage cylinder, a stirring shaft provided in the inner cavity of the nutrient storage cylinder, several sets of stirring blades fixedly connected to the outer side of the stirring shaft, a bottom-perforated disc fixedly connected below the stirring shaft, an outer fixing platform fixedly connected to the outer side of the nutrient storage cylinder, and a positioning hole opened on the side of the outer fixing platform.

[0008] As a further improvement of this utility model: the number of the first positioning grooves is the same as that of the spring grooves, and is twice that of the second positioning grooves.

[0009] As a further improvement of this utility model: when the supporting spring is naturally extended without being subjected to external force, the rounded part of the rounded top block just extends out of the spring groove.

[0010] As a further improvement of this utility model: a matching sealing cover is provided above the filling slot, and the rotating shaft of the drive motor passes through the upper cover of the nutrient storage cylinder and is fixedly connected to the stirring shaft in its inner cavity.

[0011] As a further improvement of this utility model: the inner side of the lower perforated disc is provided with three sets of through holes that are equidistant from each other and are adapted to the size and position of the leakage holes.

[0012] As a further improvement of this utility model: each set of timed and quantitative supply mechanisms is provided with two sets of positioning holes on the inner side, the size and position of the positioning holes are adapted to the round top block, and each set of outer fixed platform is fixedly connected with a positioning block adapted to the first positioning groove and the second positioning groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, an appropriate number of timed and quantitative supply mechanisms can be selected according to the type of nutrients required. During installation, the outer positioning block of the outer fixed platform of the timed and quantitative supply mechanism is pushed into the selected positioning groove, and at the same time, the round top block is squeezed and compressed back. When the positioning hole moves to the round top block, the support spring is released, pushing the round top block into the positioning hole to form an elastic self-locking mechanism, ensuring that the supply mechanism is stable and reliable on the fixed support, effectively preventing vibration or displacement during equipment operation. This design facilitates the disassembly, replacement and cleaning of the timed and quantitative supply mechanism, and increases the safety of nutrient supply.

[0015] 2. In this utility model, the drive motor drives the stirring shaft and the bottom perforated disc to rotate. During the rotation, the through hole on the bottom perforated disc periodically aligns with or deviates from the drain hole fixed at the bottom of the nutrient storage cylinder. When aligned, the nutrient solution flows out through the drain hole; when deviated, it is blocked by the disc. By precisely adjusting the speed of the drive motor, the frequency (determining the interval time) of the alignment between the through hole and the drain hole and the duration of a single alignment (determining the single discharge volume) can be flexibly controlled, so as to achieve precise and reliable nutrient solution release with set time intervals and single flow rates as needed.

[0023] Reference Figures 1 to 4 In this embodiment of the invention, a nutritional support delivery device after embryo transfer includes:

[0024] The timed and quantitative supply mechanism 2 is used to deliver internal nutrients at certain time intervals and in certain quantities.

[0025] The fixed support mechanism 1 is used to fix the nutrition support delivery equipment in a suitable position and provide a stable fixed position for the timed and quantitative supply mechanism 2. The fixed support mechanism 1 includes an annular plate 11, and fixed plates 12 are symmetrically fixedly connected to both sides of the annular plate 11. Several first positioning grooves 13 and spring grooves 15 are equidistantly opened in pairs on one side of the inner wall of the fixed plate 12. Several sets of second positioning grooves 14 are equidistantly opened on one side of the inner wall of the fixed plate 12. The number of first positioning grooves 13 is the same as that of spring grooves 15 and is twice that of second positioning grooves 14. One end of a support spring 16 is fixedly connected to the inner wall of the spring groove 15. The other end of the support spring 16 is fixedly connected to a round-headed top block 17. When the support spring 16 is naturally extended without being subjected to external force, the round-headed part of the round-headed top block 17 just extends out of the spring groove 15.

[0026] The fixed support mechanism 1 uses an annular plate 11 as a basic support component for positioning and fixing the overall equipment. The fixed plate 12 extends symmetrically from both sides of the annular plate 11, providing an installation position for the timed and quantitative supply mechanism 2. The first positioning groove 13 and the spring groove 15 are arranged in groups at equal intervals, while the second positioning groove 14 is opened individually at equal intervals, providing multiple positioning points. Inside the spring groove 15, one end of the support spring 16 is fixed to the bottom of the groove, and the other end is connected to the round-headed top block 17. When no external force is applied, the support spring 16 naturally extends, pushing the round-headed top block 17 partially out of the spring groove 15. The round head of the round-headed top block 17 is designed to elastically engage with the mating parts. When an external force is applied, the round-headed top block 17 is pressed into the spring groove 15, and the support spring 16 is compressed, allowing insertion or adjustment of position. After the external force is released, the support spring 16 returns to its original length, and the round-headed top block 17 pops out and remains in the extended state, using elastic force to fix other parts, prevent displacement, and ensure the stability of the entire equipment during use.

[0027] The timed and quantitative supply mechanism 2 includes a nutrient storage cylinder 21. A set of leakage holes 22 are provided at the bottom of the nutrient storage cylinder 21. A drainage funnel 23 is fixedly connected to the bottom of the nutrient storage cylinder 21, and a nutrient delivery pipe 24 is fixedly connected to the outlet of the drainage funnel 23. A drive motor 25 is fixedly connected to the top of the upper cover of the nutrient storage cylinder 21. A feeding slot 26 is provided in the upper cover of the nutrient storage cylinder 21. A stirring shaft 27 is installed inside the inner cavity of the nutrient storage cylinder 21. A matching sealing cover is provided above the feeding slot 26. The rotation shaft of the drive motor 25 passes through the upper cover of the nutrient storage cylinder 21 and is fixedly connected to the stirring shaft 27 within its inner cavity. The outer side of the stirring shaft 27... Several sets of stirring blades 28 are fixedly connected to prevent nutrient sedimentation during long-term supply. A bottom-opening disc 29 is fixedly connected below the stirring shaft 27. Three sets of through holes with the size and position matching the leakage hole 22 are equidistantly opened on the inner side of the bottom-opening disc 29. An outer fixed platform 210 is fixedly connected to the outside of the nutrient storage cylinder 21. A positioning hole 211 is opened on the side of the outer fixed platform 210. Two sets of positioning holes 211 are provided on the inner side of each set of timed and quantitative supply mechanism 2. The size and position of the positioning holes 211 are matched with the round top block 17. A positioning block that matches the first positioning groove 13 and the second positioning groove 14 is fixedly connected to the outside of each set of outer fixed platforms 210.

[0028] After the drive motor 25 starts, the rotating shaft drives the stirring shaft 27 to rotate. The stirring blades 28 rotate with the stirring shaft 27, stirring the nutrients in the nutrient storage cylinder 21 to prevent sedimentation caused by prolonged standing. When the perforated disc 29 below the stirring shaft 27 rotates, its through hole periodically aligns with the drain hole 22 at the bottom of the nutrient storage cylinder 21. When the through hole and the drain hole 22 coincide, the nutrients flow into the drainage funnel 23 through the drain hole 22, realizing discharge control. The drive motor 25 controls the alignment time by adjusting the speed or angle, forming a timed and quantitative supply mechanism. The drainage funnel 23 collects the outflowing nutrients. Nutrient solution is directed to the target location via nutrient delivery pipe 24. Injection slot 26 is used for adding nutrient solution. Sealing cap prevents leakage. Positioning hole 211 of outer fixed platform 210 cooperates with round top block 17 of fixed support mechanism 1. The round top block 17 is locked into positioning hole 211 by the elastic force of support spring 16. Positioning block on the outside of outer fixed platform 210 is inserted into first positioning groove 13 or second positioning groove 14 of fixed plate 12. The locking effect of round top block 17 ensures that timed and quantitative supply mechanism 2 is stably installed on fixed support mechanism 1, avoiding vibration or displacement during supply.

[0029] The working principle of this utility model is as follows: First, the fixed support mechanism 1 provides stable support for the equipment. The annular plate 11 of the fixed support mechanism 1 is fixed in a suitable position as a foundation. The symmetrical fixed plates 12 on both sides provide mounting surfaces. According to the required types of nutrients, an appropriate number of timed and quantitative supply mechanisms 2 are selected. When installing the timed and quantitative supply mechanism 2, the operator aligns the positioning block of its outer fixed platform 210 and pushes it into the selected first positioning groove 13 or second positioning groove 14 on the fixed plate 12. During this process, the round-headed top block 17 in the inner spring groove 15 of the fixed plate 12 is compressed back, and the support spring 16 contracts and stores force. When the positioning hole 211 of the outer fixed platform 210 moves to the position aligned with the round-headed top block 17, the support spring 16 is released, pushing the round-headed top block 17 into the positioning hole 211, thereby firmly locking the timed and quantitative supply mechanism 2 on the fixed support mechanism 1.

[0030] Nutrient solution is injected into the inner cavity of nutrient storage cylinder 21 through the top injection slot 26 of the timed and metered supply mechanism 2. After filling, the sealing cap is tightened to prevent leakage. When supply is needed, the drive motor 25 is started. The rotating shaft of the drive motor 25 drives the stirring shaft 27 extending into the nutrient storage cylinder 21 below to start rotating. Multiple sets of stirring fan blades 28 installed on the outside of the stirring shaft 27 rotate accordingly to continuously stir the nutrient solution in the cylinder, preventing the nutrients from precipitating or stratifying during storage and supply, and ensuring the uniformity of solution composition.

[0031] The bottom end of the stirring shaft 27 is fixedly connected to the lower perforated disc 29. The drive motor 25 drives the stirring shaft 27 and the lower perforated disc 29 to rotate together. The lower perforated disc 29 has three sets of through holes equidistantly arranged in a ring. The size and position of these through holes correspond to the leakage holes 22 at the bottom of the nutrient storage cylinder 21. During the rotation, the through holes of the lower perforated disc 29 periodically align with the fixed-position leakage holes 22. When the two coincide, the nutrient solution in the nutrient storage cylinder 21 flows out through the leakage holes 22 under the action of gravity. When the rotation causes the through holes to be misaligned, the solid part of the lower perforated disc 29 blocks the leakage holes 22 and prevents the liquid from flowing out.

[0032] The nutrient solution flowing out of the leakage hole 22 falls into the drainage funnel 23 fixedly connected below the nutrient storage cylinder 21. The drainage funnel 23 collects the flowing liquid and delivers it directionally to the target location (such as the catheter inlet related to the embryo transfer area) through the nutrient delivery tube 24 connected to its outlet. The rotation speed of the drive motor 25 precisely controls the frequency and duration of the alignment between the through hole of the lower perforated disc 29 and the leakage hole 22, thereby realizing the function of discharging a predetermined amount of liquid at preset time intervals.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
