Description

Technical Field

[0001] This utility model relates to the field of syringe technology, and in particular to a multifunctional syringe kit. Background Technology

[0002] A syringe is a common medical device used to draw gas or liquid. Syringes can also be used in medical devices, containers, and some scientific instruments in chromatography to inject through a rubber diaphragm. Syringe barrels can be made of plastic or glass and usually have graduations indicating the volume of liquid in the syringe. With the continuous development of technology, people have increasingly higher requirements for the manufacturing process of syringes.

[0003] Existing syringes have certain drawbacks in use. When adding liquid to a bottle, it is difficult to stopper it completely when it is full. Forcing the stopper in can easily cause the bottle to burst, so there is often some air left in the bottle. As the ambient temperature rises, the volume of liquid in the bottle expands and increases. When the temperature continues to rise, the stopper may come off the bottle, causing liquid leakage. If the stopper is secure, the bottle may eventually burst, which has certain adverse effects on the actual use. To address these issues, we propose a multi-functional syringe kit. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a multifunctional syringe kit. After venting, the liquid inside the bottle expands in volume as the temperature rises, and the push rod moves outward along with the piston to achieve a balance in the liquid volume expansion. This avoids the risk of a sealed bottle filled with liquid bursting due to volume expansion, effectively solving the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a multifunctional syringe kit, including a bottle, a cylindrical silicone tube installed on the upper end of the bottle, a connector sealed to the cylindrical silicone tube, an outlet silicone tube and an inlet silicone tube sealed to the connector, both the outlet silicone tube and the inlet silicone tube being connected to a right syringe push-pull rod, a syringe syringe sleeve fitted on the outside of the syringe push-pull rod, and an elliptical silicone piston provided between the syringe syringe and the syringe push-pull rod, a push rod assembly connected to the end of the syringe push-pull rod, a right rubber stopper positioned at the end of the push rod assembly, and PP adhesive tape installed on the connector.

[0006] Preferably, a long column is provided inside the syringe barrel. The syringe barrel, syringe push rod, and elliptical silicone piston are combined to form two spaces. The column in the middle of the syringe barrel is connected to the outlet silicone tube and is connected to the internal space of the syringe push rod through the long column inside the syringe barrel, the elliptical silicone piston, and to form a space. The column on the outside of the syringe barrel is connected to the inlet silicone tube through the internal space of the syringe barrel.

[0007] Preferably, in step one, the bottle, cylindrical silicone tube, and connector are snapped together, and the outlet silicone tube and inlet silicone tube are assembled and sealed on the connector. Liquid is added into the bottle through the inlet silicone tube. At this time, air in the bottle will enter with the liquid and be discharged out of the bottle through the outlet silicone tube until the bottle is basically full of liquid.

[0008] Preferably, in step two, the outlet silicone tube and the inlet silicone tube are detached from the connector and connected to the syringe barrel. First, the syringe push-pull rod is pushed all the way to expel all the air in the inner space, and the syringe barrel is held upright. The outlet silicone tube and the inlet silicone tube are inserted into the liquid, and the syringe push-pull rod is pulled upward. The liquid enters the inner space and the outer space together. Throughout the second step, the syringe push-pull rod and the rubber stopper at the top of the push rod assembly are in the open state.

[0009] Preferably, in step three, the outlet silicone tube and the inlet silicone tube are correctly connected to the connector assembled on the bottle. The syringe barrel remains vertical. The syringe push rod is pushed down to inject the liquid in the inner space into the bottle. The air in the bottle will be discharged to the outer space through the connector, the outlet silicone tube, and the inner column of the syringe barrel. When the syringe push rod is pushed to the top, all the air in the outer space will also be discharged through the opening at the top of the syringe push rod. Then the rubber stopper is plugged in, and the bottle venting is completed.

[0010] Preferably, in step four, after the bottle has finished venting, the liquid inside the bottle expands in volume as the temperature rises, and the syringe push rod moves outward along with the elliptical silicone piston to achieve a balance in the expansion of the liquid volume.

[0011] Compared with the prior art, this utility model provides a multifunctional syringe kit with the following beneficial effects: In the first step, the bottle, cylindrical silicone tube, and connector are snapped together. The outlet silicone tube and inlet silicone tube are assembled and sealed on the connector. Liquid is added into the bottle through the inlet silicone tube. At this time, air in the bottle will enter with the liquid and be discharged out of the bottle through the outlet silicone tube until the bottle is basically full of liquid. In the second step, the outlet silicone tube and inlet silicone tube are detached from the connector and connected to the syringe barrel. First, the syringe push rod is pushed all the way to expel all the air in the inner space. The syringe barrel is then held upright. The outlet silicone tube and inlet silicone tube are inserted into the liquid. The syringe push rod is pulled upward, and the liquid enters the inner and outer spaces together. Throughout the second step, the syringe push rod and the rubber stopper at the top of the push rod assembly are in the open state. In the third step, the outlet silicone tube and inlet silicone tube are correctly connected... When the syringe is attached to the connector on the bottle, the syringe barrel remains vertical. Pushing the syringe plunger downwards injects liquid into the bottle. Air inside the bottle is expelled through the connector, the outlet silicone tube, and the internal column of the syringe barrel to the outer space. When the syringe plunger is pushed to the top, all air in the outer space is also expelled through the opening at the top of the plunger. Then, the stopper is inserted, completing the bottle venting process. In step four, after venting, the liquid inside the bottle expands with the rising temperature. The syringe plunger moves outwards along with the elliptical silicone piston to achieve equilibrium in the liquid's expansion. This avoids the risk of a sealed bottle filled with liquid bursting due to volume expansion. The entire syringe structure is simple, easy to operate, and performs better than traditional methods.

[0022] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figure 1-9 As shown, a multifunctional syringe kit includes a bottle 1, with a cylindrical silicone tube 2 installed on the upper end of the bottle 1. A connector 3 is sealed to the cylindrical silicone tube 2, and an outlet silicone tube 5 and an inlet silicone tube 6 are sealed to the connector 3. Both the outlet silicone tube 5 and the inlet silicone tube 6 are connected to a right syringe push-pull rod 9. A syringe syringe 7 is sleeved on the outside of the syringe push-pull rod 9, and an elliptical silicone piston 8 is provided between the syringe syringe 7 and the syringe push-pull rod 9. A push rod assembly 10 is connected to the end of the syringe push-pull rod 9, and a right rubber stopper 11 is positioned at the end of the push rod assembly 10. PP adhesive tape 4 is installed on the connector 3. After venting, the liquid inside the bottle expands in volume as the temperature rises, and the push rod moves outward with the piston to achieve a balance in the liquid volume expansion, thereby avoiding the risk of the sealed bottle filled with liquid bursting due to volume expansion.

[0024] Furthermore, a long column is provided inside the syringe barrel 7. The syringe barrel 7, syringe push rod 9, and elliptical silicone piston 8 are combined to form two spaces. The column in the middle of the syringe barrel 7 is connected to the outlet silicone tube 5, and is connected to the internal space of the syringe push rod 9 through the long column inside the syringe barrel 7, the elliptical silicone piston 8, and to form a space. The column on the outside of the syringe barrel 7 is connected to the inlet silicone tube 6 through the internal space of the syringe barrel 7.

[0025] Furthermore, in step one, the bottle 1, the cylindrical silicone tube 2, and the connector 3 are fitted together. The outlet silicone tube 5 and the inlet silicone tube 6 are fitted onto the connector 3 and sealed. Liquid is added into the bottle through the inlet silicone tube 6. At this time, the air in the bottle will enter with the liquid and be discharged out of the bottle through the outlet silicone tube 5 until the bottle is basically full of liquid.

[0026] Furthermore, in step two, the outlet silicone tube 5 and the inlet silicone tube 6 are detached from the connector 3 and connected to the syringe barrel 7. First, push the syringe push rod 9 all the way down to expel all the air in the inner space, and then stand the syringe barrel 7 upright. Insert the outlet silicone tube 5 and the inlet silicone tube 6 into the liquid and pull the syringe push rod 9 upward. The liquid enters the inner space and the outer space together. Throughout the second step, the syringe push rod 9 and the rubber stopper 11 at the top of the push rod assembly 10 are in the open state.

[0027] Furthermore, in step three, the outlet silicone tube 5 and the inlet silicone tube 6 are correctly connected to the connector 3 assembled on the bottle 1. The syringe barrel 7 remains vertical. The syringe push rod 9 is pushed down to inject the liquid in the inner space into the bottle 1. The air in the bottle 1 will be discharged to the outer space through the connector 3, the outlet silicone tube 5, and the inner column of the syringe barrel 7. When the syringe push rod 9 is pushed to the top, all the air in the outer space will also be discharged through the opening at the top of the syringe push rod 9. Then the rubber stopper 11 is inserted. At this point, the air discharge of the bottle 1 is completed.

[0028] Furthermore, in step four, after bottle 1 completes the venting, the liquid inside bottle 1 expands in volume as the temperature rises, and the syringe push rod 9 moves outward along with the elliptical silicone piston 8 to achieve a balance in the expansion of the liquid volume.

[0029] One of the simplest implementations of this application is to prevent a sealed bottle filled with liquid from bursting due to volume expansion. Figure 8 and Figure 9 As shown, a regular syringe is connected to the bottle via a tube. When the liquid inside the bottle expands due to the increase in ambient temperature, the piston of the syringe moves outward to achieve a balance between the expansion of the liquid volume, thus avoiding the risk of the sealed bottle filled with liquid bursting due to volume expansion.

[0030] Working Principle: This utility model includes a bottle 1, a cylindrical silicone tube 2, a connector 3, PP adhesive tape 4, an outlet silicone tube 5, an inlet silicone tube 6, a syringe barrel 7, an elliptical silicone piston 8, a syringe push-pull rod 9, a push rod assembly 10, and a rubber stopper 11. In step one, the bottle 1, the cylindrical silicone tube 2, and the connector 3 are fitted together. The outlet silicone tube 5 and the inlet silicone tube 6 are assembled and sealed onto the connector 3. Liquid is added into the bottle through the inlet silicone tube 6. At this time, air in the bottle will enter with the liquid and be expelled from the bottle through the outlet silicone tube 5 until the bottle is basically full of liquid. In step two, the outlet silicone tube 5 and the inlet silicone tube 6 are detached from the connector 3 and connected to the syringe barrel 7. First, the syringe push-pull rod 9 is pushed all the way to expel all the air in the inner space. The syringe barrel 7 is then held upright. The outlet silicone tube 5 and the inlet silicone tube 6 are inserted into the liquid. The syringe push-pull rod 9 is pulled upwards, and the liquid enters the inner and outer spaces together. Throughout the second step, the syringe push-pull rod 9 and the push rod assembly 10 are used. In step three, the rubber stopper 11 at the top of bottle 1 is open. The outlet silicone tube 5 and inlet silicone tube 6 are correctly connected to the connector 3 mounted on bottle 1. The syringe barrel 7 remains vertical. The syringe push rod 9 is pushed downwards to inject the liquid from the inner space into bottle 1. The air inside bottle 1 is then expelled to the outer space through connector 3, outlet silicone tube 5, and the internal column of syringe barrel 7. When the syringe push rod 9 is pushed to the top, all the air in the outer space is also expelled through the opening at the top of the syringe push rod 9. Then, the rubber stopper 11 is inserted, thus completing the venting of bottle 1. In step four, after venting, the liquid inside bottle 1 expands with the rising temperature. The syringe push rod 9 moves outwards along with the elliptical silicone piston 8 to achieve a balance in liquid volume expansion. This avoids the risk of a sealed bottle filled with liquid bursting due to volume expansion. The above describes 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 this utility model as claimed.
