Description

Technical Field

[0001] This utility model relates to the field of assisted reproductive gel technology, specifically to a quantitative extrusion device for assisted reproductive gel. Background Technology

[0002] Assisted reproductive gel is a specialized gel used in assisted reproductive technologies. Its main functions include improving the reproductive tract environment, assisting sperm transport, increasing fertilization success rates, and supporting embryo implantation. It is typically made of biocompatible materials containing ingredients beneficial to fertility. It mimics natural cervical mucus, reduces friction damage during procedures, helps sperm move within the reproductive tract, and increases the probability of reaching the egg. When using assisted reproductive gel, it must be squeezed out of the gel tube.

[0003] To avoid waste and side effects from overuse, assisted reproductive gels should be dispensed in measured amounts during use.

[0004] However, most existing assisted reproductive gels are manually squeezed by the operator during use. Since the gel is not a liquid, the high viscosity of the gel causes greater resistance when it is squeezed out of the syringe, requiring a large amount of pressure. This can easily lead to excessive gel being squeezed out due to excessive pressure, or insufficient gel being squeezed out due to air in the dispensing nozzle. The accuracy of gel extrusion cannot be guaranteed. To address this, we propose a quantitative extrusion device for assisted reproductive gel. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a quantitative extrusion device for assisted reproductive gel, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a quantitative extrusion device for assisted reproductive gel, comprising:

[0008] A gel tube, wherein an outer shell is provided on the outside of the gel tube and a piston for squeezing the gel inside the gel tube is provided on the inside of the gel tube;

[0009] The extrusion mechanism includes a micro motor mounted on the outside of the housing. The micro motor is fixedly connected to a threaded rod via an output shaft. An internal threaded block is threadedly connected to the outside of the threaded rod. A connecting rod is fixedly connected to the outside of the internal threaded block. A push block is fixedly connected to the other end of the connecting rod.

[0010] The support mechanism includes a base disposed below the gel tube, a bracket fixedly connected to the top of the base, and an arc-shaped block fixedly connected to the other end of the bracket.

[0011] Preferably, a battery for providing power to the micro motor is installed inside the housing, and a squeeze switch for controlling the start of the micro motor is provided on the outside of the housing.

[0012] Preferably, a limiting rod is fixedly connected to the inner side of the outer shell, a connecting ring is fixedly connected to the outer side of the internal threaded block, and the other end of the limiting rod passes through the connecting ring and is slidably connected to the inner wall of the connecting ring.

[0013] Preferably, a limiting ring is fixedly connected to the outside of the gel tube, and an external threaded ring is fixedly connected to the outside of the gel tube, with the outer shell threadedly connected to the outside of the external threaded ring.

[0014] Preferably, the bottom of the base is provided with two symmetrically distributed adhesive strips.

[0015] Preferably, a protective sleeve is fixedly connected to the top of the base, and the inner wall of the protective sleeve is fitted to the outer side of the gel tube's outlet.

[0016] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0017] 1. This utility model, through the setting of the extrusion mechanism, allows the micro motor to be started by pressing the extrusion switch when using the assisted reproductive gel. Under the action of the pusher, the gel in the gel tube is pushed out at a uniform speed, avoiding the phenomenon of too much or too little gel being extruded due to different pressure during manual extrusion, thus ensuring the accuracy of gel use.

[0018] 2. By setting up a support mechanism, this utility model can support the gel tube containing assisted reproductive gel when it is not in use. This not only protects the gel outlet from dust adsorption, but also allows the gel inside the gel tube to gather at the gel outlet by tilting the gel tube. The air inside the gel tube is located at the piston, which further improves the accuracy of gel extrusion. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments. Example 1:

[0030] Reference Figure 1-5 This is the first embodiment of the present invention, which discloses a quantitative extrusion device for assisted reproductive gel, comprising:

[0031] A gel tube 1 is provided with a shell 2 on the outside of the gel tube 1 and a piston 101 for squeezing the gel inside the gel tube 1 is provided on the inside of the gel tube 1.

[0032] The gel tube 1 is positioned with an open end inside the outer shell 2, so that when the gel tube 1 is inserted into the outer shell 2, the pusher 408 can contact the outside of the piston 101.

[0033] The end of the gel tube 1 away from the piston 101 is provided with an outlet for discharging the fertility-aiding gel inside, and a one-way valve is provided inside the outlet.

[0034] The extrusion mechanism 4 includes a micro motor 402 installed on the outside of the housing 2. The micro motor 402 is fixedly connected to a threaded rod 409 via an output shaft. An internal threaded block 411 is threadedly connected to the outside of the threaded rod 409. A connecting rod 407 is fixedly connected to the outside of the internal threaded block 411. A push block 408 is fixedly connected to the other end of the connecting rod 407.

[0035] The micro motor 402 can drive the threaded rod 409 to rotate through the output shaft, and under the action of the internal threaded block 411, it drives the push block 408 to move, squeezing the piston 101, thereby squeezing out the assisted reproductive gel in the gel tube 1.

[0036] Specifically, a battery 405 for providing power to the micro motor 402 is installed inside the housing 2, and a squeeze switch 404 for controlling the start of the micro motor 402 is provided on the outside of the housing 2. The battery 405, the squeeze switch 404 and the micro motor 402 are electrically connected. An encoder for controlling the number of rotations of the micro motor 402 is electrically connected to the micro motor 402.

[0037] It should be noted that the connection and control between the micro motor 402 and the encoder are existing technologies and are well known in the field, so they will not be described in detail here.

[0038] Specifically, a limiting rod 406 is fixedly connected to the inner side of the outer shell 2, and a connecting ring 410 is fixedly connected to the outer side of the internal thread block 411. The other end of the limiting rod 406 passes through the connecting ring 410 and is slidably connected to the inner wall of the connecting ring 410.

[0039] The limiting rod 406 can slide on the inner wall of the connecting ring 410. Under the action of the two limiting rods 406 and the two connecting rings 410, the movement trajectory of the internal thread block 411 is limited, ensuring that the internal thread block 411 can only move in a fixed direction when the thread rod 409 rotates, so as to squeeze the piston 101 through the push block 408.

[0040] Specifically, a limiting ring 401 is fixedly connected to the outside of the gel tube 1, and an external threaded ring 403 is fixedly connected to the outside of the gel tube 1. The outer shell 2 is threadedly connected to the outside of the external threaded ring 403.

[0041] The external threaded ring 403 facilitates the connection between the gel tube 1 and the outer shell 2. The limiting ring 401 restricts the depth of the gel tube 1 entering the inner shell 2. When the outer side of the outer shell 2 contacts the limiting ring 401, the push block 408 contacts the outer side of the piston 101. Example 2:

[0042] Reference Figure 1-5 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0043] The support mechanism 3 includes a base 301 located below the gel tube 1, a bracket 302 fixedly connected to the top of the base 301, and an arc-shaped block 305 fixedly connected to the other end of the bracket 302.

[0044] The support 302 and the arc block 305 support the gel tube 1 and the outer shell 2, making them tilted. This allows the assisted reproductive gel inside to squeeze the internal gas backward, preventing gas from being squeezed out during the next use and ensuring extrusion accuracy.

[0045] Specifically, the bottom of the base 301 is provided with two symmetrically distributed adhesive strips 303.

[0046] The adhesive strip 303 can fix the base 301 in a proper position, thereby ensuring the stability of the base 301 and facilitating the support of the bracket 302 and the arc block 305 to support the gel tube 1.

[0047] Specifically, a protective sleeve 304 is fixedly connected to the top of the base 301, and the inner wall of the protective sleeve 304 is fitted to the outer side of the gel tube 1's dispensing port.

[0048] The protective sleeve 304 protects the dispensing nozzle of the gel tube 1, preventing dust from accumulating at the nozzle when the gel tube 1 is not in use and thus avoiding harm to the user.

[0049] The remaining structure is the same as that in Example 1.

[0050] The workflow of this utility model is as follows:

[0051] The base 301 is fixed in a suitable position using adhesive strip 303;

[0052] Before using the gel tube 1 containing assisted reproductive gel, connect it to the outer shell 2 through the external threaded ring 403 until the outer side of the outer shell 2 contacts the limiting ring 401. At this time, the connection between the gel tube 1 and the outer shell 2 is completed.

[0053] When assisted reproductive gel is needed, the number of presses is determined by manually pressing the extrusion switch according to the required measurement. When the extrusion switch 404 is pressed, the micro motor 402 drives the threaded rod 409 to rotate through the output shaft. The rotation of the threaded rod 409 drives the internal threaded block 411 to move towards the gel tube 1. The movement of the internal threaded block 411 pushes the piston 101 to move through the connecting rod 407 and the push block 408, thereby extruding the assisted reproductive gel in the gel tube 1 in a measured amount.

[0054] After obtaining an appropriate amount of assisted reproductive gel, the gel tube 1 is aligned with the protective sleeve 304 and placed inside the arc-shaped block 305. The arc-shaped block 305 and the limiting ring 401 support the gel tube 1 and the outer shell 2. When the gel tube 1 is placed on the support mechanism 3, the gel tube 1 is in an inclined state, and the assisted reproductive gel in the gel tube 1 gathers towards the gel tube 1's outlet, making it convenient for the next extrusion.

[0055] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
