Description

Technical Field

[0001] The utility model relates to a foam preparation device, in particular to a foam preparation device for a cyst sclerosing agent under ultrasound guidance, and belongs to the technical field of medical auxiliary equipment. Background Art

[0002] In the field of modern medicine, the treatment of cystic diseases has always been one of the focuses of clinical attention. Ultrasound-guided cyst sclerotherapy, as a minimally invasive and effective treatment method, has gradually been widely used. Its principle is to inject sclerosant foam into the cyst to cause aseptic inflammation of the cyst wall, thereby promoting cyst atrophy and fibrosis to achieve the treatment purpose.

[0003] In the prior art, a foam sclerosant preparation device disclosed in Publication No. CN221384679U has a syringe threadedly connected to a three-way housing, making the entire device safe. This not only prevents the syringe from falling off from the medical three-way connector, thus avoiding drug waste caused by falling off, but also has a simple structure and precise operation, which greatly shortens the time for preparing the foam sclerosant, improves efficiency, and meets the needs of users. The above-mentioned prior art solution has the following shortcomings: before injecting the foam sclerosant, the foam sclerosant is formed by manually pushing and pulling two syringes alternately. The manual pushing and pulling method is greatly affected by factors such as the operator's strength, speed, and stirring skills, resulting in poor uniformity of the foam prepared each time, and the consistency between different batches cannot be guaranteed. This may not only affect the distribution effect of the sclerosant in the cyst and reduce the accuracy of treatment, but also present uneven echoes under ultrasound imaging, interfering with the doctor's judgment of the internal condition of the cyst and increasing the difficulty and risk of treatment. Summary of the Invention

[0004] The purpose of the present utility model is to provide a foam preparation device for cyst sclerosing agents under ultrasound guidance in order to solve the problem that the manual push-pull preparation method of the above-mentioned device is greatly affected by factors such as the operator's strength, speed and stirring skills, resulting in poor uniformity of the foam prepared each time and the inability to ensure consistency between different batches.

[0005] The utility model achieves the above-mentioned object through the following technical solutions: a foam preparation device for cyst sclerosing agent under ultrasound guidance, comprising a base plate;

[0006] Two preparation cylinders are provided on the surface of the base plate, and the output ports of the two preparation cylinders are plugged with the same three-way pipe. Two preparation cylinder grooves compatible with the preparation cylinders are provided on the surface of the base plate, and the two preparation cylinders are respectively clamped in the corresponding preparation cylinder grooves. A piston rod is slidably connected in the preparation cylinder, and one end of the piston rod passes through the preparation cylinder and is a T-shaped structure. An arc-shaped electric guide rail is installed in the arc groove provided on the surface of the base plate, and an arc-shaped slide is slidably connected to the surface of the arc-shaped electric guide rail.

One end of the two L-shaped slide rods is integrally formed with a clamping sleeve, and the T-shaped ends of the two piston rods are respectively clamped in the two clamping sleeves.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1, as Figures 1 to 6 As shown, a foam preparation device for cyst sclerosing agent under ultrasound guidance includes a base plate 1;

[0024] Two preparation cylinders 2 are provided on the surface of the base plate 1, and the output ports of the two preparation cylinders 2 are plugged with the same three-way pipe 3. Two preparation cylinder grooves 6 are provided on the surface of the base plate 1 to match the preparation cylinder 2. The two preparation cylinders 2 are respectively clamped in the corresponding preparation cylinder grooves 6. A piston rod 10 is slidably connected in the preparation cylinder 2, and one end of the piston rod 10 passes through the preparation cylinder 2 and is a T-shaped structure. An arc-shaped electric guide rail 16 is installed in the arc groove provided on the surface of the base plate 1, and an arc-shaped slide 14 is slidably connected to the surface of the arc-shaped electric guide rail 16. Two wave grooves 15 are symmetrically provided on the surface of the arc-shaped slide 14, and L-shaped slide rods 12 are slidably connected in the two wave grooves 15. One end of the two L-shaped slide rods 12 is integrally formed with a clamping sleeve 13, and the T-shaped ends of the two piston rods 10 are respectively clamped in the two clamping sleeves 13.

[0025] The design of the two preparation cylinders 2, the arc-shaped electric guide rails 16, the arc-shaped slide plate 14 and the related linkage parts provides a precise and stable stirring mechanism for the mixing of the hardener and the gas. The arc-shaped electric guide rails 16 drive the arc-shaped slide plate 14 to move along a specific arc-shaped trajectory, so that the L-shaped slide bar 12 in the wave groove 15 on the slide plate surface performs reciprocating motion, and the ferrule 13 at one end of the L-shaped slide bar 12 is tightly connected to the T-shaped end of the piston rod 10, thereby driving the piston rod 10 to move regularly in the preparation cylinder 2. This design can ensure that the hardener and the gas are fully, continuously and evenly stirred in the preparation cylinder 2, avoiding the problem of local uneven mixing that may occur in traditional stirring methods, and helping to prepare high-quality The cyst sclerosing agent foam with uniform surface and consistent bubble size provides a reliable pharmaceutical basis for subsequent ultrasound-guided treatment. The preparation barrel groove 6 opened on the bottom plate 1 and adapted to the preparation barrel 2 allows the preparation barrel 2 to be accurately and conveniently clipped into the corresponding position. On the one hand, this design provides clear installation instructions for the operator during the installation process, reduces the installation time and operation difficulty, and improves the assembly efficiency of the device. On the other hand, the preparation barrel groove 6 can firmly fix the preparation barrel 2 to prevent the preparation barrel 2 from being displaced during violent operations such as stirring, thereby ensuring the stability and reliability of the entire foam preparation process and avoiding problems such as shaking of the preparation barrel 2 affecting the stirring effect or causing material leakage.

[0026] Furthermore, a matching sealing plug 5 is inserted into one end of the tee pipe 3 .

[0027] When there is no need to transfer materials or export foam, the sealing plug 5 is tightly inserted into one end of the tee pipe 3. Its adaptive design can form a reliable seal, which effectively prevents the hardener, gas or formed foam in the preparation cylinder 2 from leaking out from the idle port of the tee pipe 3, avoiding waste of materials. At the same time, it also eliminates the pollution to the surrounding environment caused by leakage, ensuring the cleanliness and safety of the operation area.

[0028] Furthermore, a valve 4 is installed on the surface of the tee pipe 3 .

[0029] Valve 4 can accurately control the fluid flow between the two preparation cylinders 2 through the three-way pipe 3. By adjusting the opening and closing degree of valve 4, the exchange speed of the hardener foam between the two preparation cylinders 2 can be determined according to actual needs. In the early stage of foam preparation, when the hardener and gas are just injected into the preparation cylinder 2 and the substances in each barrel have not been fully mixed, the opening of valve 4 can be adjusted to a small degree to allow the substances in the two preparation cylinders 2 to be slowly exchanged. As the preparation progresses, the opening of valve 4 is gradually increased to accelerate the flow of foam between the two barrels, further promoting the uniform mixing of the foam, thereby ensuring that high-quality, uniform and consistent cyst hardener foam is finally obtained.

[0030] Furthermore, the two preparation cylinders 2 are both made of transparent material.

[0031] The preparation tube 2 is made of transparent material. This design provides great convenience for the operator. During the entire process of hardener injection, gas introduction and foam preparation, the operator can directly observe the status of the internal material through the preparation tube 2, including the liquid level of the hardener, the generation and distribution of bubbles, the progress of foam formation, etc.

[0032] The second embodiment is improved on the basis of the first embodiment: the surfaces of the L-shaped sliding rods 12 are slidably connected with fixed guide blocks 11 , and the fixed guide blocks 11 are fixedly mounted on the surface of the bottom plate 1 .

[0033] The fixed guide block 11 provides a clear direction of movement for the L-shaped slide bar 12. When the foam preparation device is running, the L-shaped slide bar 12 needs to reciprocate under the drive of the wave groove 15 to drive the piston rod 10 to perform piston movement in the preparation cylinder 2. The fixed guide block 11 ensures that the L-shaped slide bar 12 can only slide back and forth in the same direction to prevent it from shifting left and right or tilting during movement, making the movement trajectory of the L-shaped slide bar 12 more precise.

[0034] An elastic band 7 is fixedly installed on the surface of the bottom plate 1 and located on one side of the preparation barrel groove 6. A clamping rod 8 is integrally formed at one end of the elastic band 7. A clamping hook 9 is installed on the surface of the bottom plate 1 and located at a position corresponding to the elastic band 7.

[0035] Insert the clamping rod 8 at one end of the elastic band 7 into the corresponding clamping hook 9 on the bottom plate 1, so that the elastic band 7 is tightly bound to the outside of the preparation tube 2, further strengthening the fixing effect of the preparation tube 2 and preventing the preparation tube 2 from loosening during the foam preparation process.

[0036] When in use, first, pick up two clean and dry preparation tubes 2. Since they are made of transparent material, it can be confirmed that there are no residual impurities inside, and inject a quantitative volume of cyst hardening agent into the preparation tube 2. Align the preparation tube 2 with the preparation tube groove 6 on the surface of the bottom plate 1 and gently insert it to ensure that the preparation tube 2 is tightly fitted and firmly connected to the bottom of the groove and will not shake or shift during subsequent operations. The ports of the two preparation tubes 2 should be aligned with the interface position of the tee pipe 3 for convenient and stable insertion. Subsequently, the clamping rod 8 at one end of the elastic band 7 is inserted into the corresponding clamping hook 9 on the bottom plate 1, so that the elastic band 7 is tightly bound to the outside of the preparation tube 2, further strengthening the fixing effect of the preparation tube 2 and preventing the preparation tube 2 from loosening during the foam preparation process. Subsequently, align the T-shaped end of the piston rod 10 with the clamping sleeve 13 at one end of the L-shaped slide rod 12, and clamp it with force to ensure that the connection is tight and there is no sign of looseness.

[0037] The arc-shaped electric guide rail 16 is activated, causing the arc-shaped slide 14 to move slowly along the arc-shaped trajectory. As the arc-shaped slide 14 moves, the L-shaped slide rod 12 in the wavy groove 15 on its surface reciprocates under the guidance of the wavy path. Since the L-shaped slide rod 12 is tightly connected to the piston rod 10 through the ferrule 13, the piston rod 10 then performs regular piston motion in the preparation barrel 2. The relative reciprocating motion of the two piston rods 10 mixes the hardener and gas, causing the hardener to be continuously drawn and dispersed from the two preparation barrels 2, facilitating the uniform mixing of the gas therein and accelerating the formation of foam.

[0038] When it is observed that the foam in the preparation tube 2 reaches the ideal quality standard, such as fine and uniform foam, moderate bubble size, and clear imaging under ultrasonic simulation environment (simulation detection can be carried out in advance), stop the operation of the arc-shaped electric guide rail 16, carefully pull out the sealing plug 5 at one end of the tee pipe 3, quickly connect the sterile collection container to the open end of the tee pipe 3, and slowly open the valve 4 to allow the prepared cyst sclerosing agent foam to flow smoothly into the collection container.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
