Abstract
Description
Technical Field
[0001] This utility model relates to the field of immunomodulator emulsification technology, and in particular to a syringe emulsification device. Background Technology
[0002] For animal immunization using oily adjuvants (such as Freund's adjuvant), the antigen must be emulsified. Currently, the most commonly used emulsification method in small domestic biotechnology companies and biomedical research is the double-push syringe method, which involves connecting the outlets of two syringes with tubing and then injecting back and forth. This method is widely used due to its low cost, high accessibility, and high antigen utilization rate. In addition to infusion tubing, commercially available rigid plastic tubing is now available for the connector assembly used in the double-push method. Improved rigid plastic tubing (such as the antigen emulsification device disclosed in publication number CN217449686U) has also emerged, further optimizing the emulsification effect.
[0003] However, when injecting through the rigid plastic tube, if the two hands are not aligned in a straight line, the forces from these opposing directions will eventually act on the connection between the syringe outlet and the rigid plastic tube, causing the connection to loosen or gap. The strong pressure inside the syringe will then cause the emulsion to spray out through this gap, resulting in loss. If the force is slightly greater, the rigid plastic tube may even detach from the syringe outlet, causing the entire emulsion to leak out, resulting in irreparable damage. To address the shortcomings of existing technologies, we propose a syringe emulsification device. Utility Model Content
[0004] The main objective of this invention is to provide a syringe emulsification device that can effectively solve the problems in the prior art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A syringe emulsification device includes two sets of syringe tubes symmetrically arranged. A connecting rigid tube connects the injection heads of the two sets of syringe tubes. Two sets of handles are symmetrically arranged on the outer walls of the outer ends of the two sets of syringe tubes. A positioning sleeve is nested on the outer walls of the two sets of syringe tubes. The upper end of the positioning sleeve has an opening, and both sides of the lower end of the positioning sleeve have latches. The two ends of the opening and the two sets of latches are respectively engaged with the two sets of handles on the outer sides of the two sets of syringe tubes. Velcro is wrapped around the middle outer wall of the positioning sleeve.
[0006] Preferably, the length of the positioning sleeve is the same as the length of the two sets of syringe tubes connected by a connecting rigid tube.
[0007] Preferably, the positioning sleeve is made of a tough plastic material, the inner diameter of the positioning sleeve is the same as the outer diameter of the syringe tube, and the opening size of the opening and the two sets of latches is the same as the width of the part of the handle near the outer wall of the syringe tube.
[0008] Preferably, both ends of the connecting rigid tube are sealed to the injection heads of the two sets of syringe tubes, and a microfluidic separator is provided inside one end of the connecting rigid tube. The microfluidic separator is a sieve plate disposed inside the port cavity of the connecting rigid tube.
[0009] Preferably, the outer side of the hook and loop fastener is a rough surface, the inner side of the hook and loop fastener is a hook surface, the length of the hook and loop fastener can be wrapped around the outer wall of the positioning sleeve twice, and the inner end of the hook and loop fastener is attached to the outer wall of the positioning sleeve with adhesive.
[0010] Preferably, a piston rod is movably connected to the middle of the interior of each of the two sets of syringe tubes, and a piston head is movably connected to the inner end of each of the two sets of piston rods inside the two sets of syringe tubes, and a push plate is fixed to the outer end of each of the two sets of piston rods outside the two sets of syringe tubes.
[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. In this utility model, the positioning sleeve and Velcro can fix the two sets of syringe tubes. When the two sets of syringes are pushed back and forth, if the force applied by the two hands is not on the same straight line, the lateral force will act on the positioning sleeve and will not act directly on the connection between the two sets of syringe tubes and the connecting rigid tube. This can eliminate the risk of emulsification leakage in the double-push method. Moreover, this structure is simple, low in cost, and easy to promote and use.
[0012] 2. In this utility model, the Velcro can further fix the positioning sleeve. The two ends of the positioning sleeve can also be engaged with the handles of the two sets of syringe tubes through the openings and the snap-fit at both ends, making the connection between the positioning sleeve and the syringe tube more stable. This can prevent the syringe from being squeezed out from the opening of the positioning sleeve, making the structure more stable and the performance better. Attached Figure Description

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0016] like Figures 1-4 As shown, a syringe emulsification device includes two sets of syringe tubes 1, symmetrically arranged. A piston rod 5 is movably connected to the center of each syringe tube 1. A piston head 10 is movably connected to the inner end of each piston rod 5 inside the syringe tube 1. A push plate 6 is fixed to the outer end of each piston rod 5 outside the syringe tube 1. Pushing the push plate 6 causes the piston head 10 to move within the syringe tube 1 via the piston rod 5, thus pushing the contents of the syringe tube 1... The liquid flows into the piston rod 5 on the other side. A set of connecting rigid tubes 9 is connected between the injection heads of the two sets of syringe tubes 1. The two ends of the connecting rigid tubes 9 are respectively sealed to the injection heads of the two sets of syringe tubes 1. A microfluidic separator 11 is provided inside one end of the connecting rigid tube 9. The microfluidic separator 11 is a sieve plate set inside the port cavity of the connecting rigid tube 9. The liquid inside the syringe tubes 1 on both sides flows back and forth and passes through the middle of the microfluidic separator 11 in the middle of the connecting rigid tube 9. By passing back and forth, the emulsification effect can be achieved.
[0017] like Figures 1-2As shown, two sets of handles 4 are symmetrically arranged on the outer walls of the outer ends of the two sets of syringe tubes 1. The handles 4 facilitate the pushing and pulling of the push plate 6. A positioning sleeve 2 is nested on the outer wall of the two sets of syringe tubes 1. The positioning sleeve 2 is used to position and fix the two sets of syringe tubes 1. When the forces applied on both sides are no longer on the same straight line, the lateral force will act on the positioning sleeve 2 to prevent the connection between the syringe tube 1 and the connecting rigid tube 9 from being unstable and causing leakage. The length of the positioning sleeve 2 is the same as the length of the two sets of syringe tubes 1 after being connected by the connecting rigid tube 9. The positioning sleeve 2 is made of tough plastic material, which facilitates the syringe tube 1 to be squeezed into the middle of the positioning sleeve 2 from the opening 8. The inner diameter of the positioning sleeve 2 is the same as the outer diameter of the syringe tube 1. The upper end of the positioning sleeve 2 is provided with an opening 8. The lower end of the positioning sleeve 2 is provided with two bayonets 7 and two openings 8. The opening size of the two sets of bayonets 7 is the same as the width of the part of the handle 4 near the outer wall of the syringe body 1. The two ends of the opening 8 and the two sets of bayonets 7 are respectively engaged with the two sets of handles 4 on the outside of the two sets of syringe bodies 1, further limiting the positioning sleeve 2 and the syringe body 1, making the connection between the positioning sleeve 2 and the syringe body 1 more stable. The middle outer wall of the positioning sleeve 2 is wrapped with Velcro 3. The outer side of Velcro 3 is rough and the inner side is hook. The length of Velcro 3 can wrap around the outer wall of the positioning sleeve 2 twice. The inner end of Velcro 3 is attached to the outer wall of the positioning sleeve 2 with adhesive. Velcro 3 can further fix the positioning sleeve 2 and the syringe body 1, preventing the syringe body 1 from being squeezed out from the opening 8 of the positioning sleeve 2.
[0018] It should be noted that this utility model is a syringe emulsification device. In use, after the syringe draws in the injection agent, the injection heads of the two sets of syringe tubes 1 are connected to the two ends of the connecting rigid tube 9. The syringe head enters the middle of the positioning sleeve 2 through the opening 8. The two ends of the opening 8 and the locking slots 7 on both sides of the lower end of the positioning sleeve 2 will engage with the two sets of handles 4 on the outside of the two sets of syringe tubes 1. Then, the Velcro 3 is wrapped around the outer wall of the positioning sleeve 2 to further reinforce the positioning sleeve 2. In this way, the injection agent can be emulsified by pressing the push plates 6 on both sides through the double push method.
[0019] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
