Problems solved by technology

[0003] The syringe in the prior art, as long as it is used once, its jacket, core rod and injection needle will be discarded, and it is impossible to realize the reuse of the syringe or some components that constitute the syringe
Not only the use cost of the patient is high, but also the components of the syringe need to be discarded after one-time use, which is a serious waste of materials and does not meet the requirements of environmental protection

Embodiment 1

[0051] A syringe for reusable booster devices such as figure 1 As shown, a liquid storage device 100 , a booster device 200 , an injection needle 300 and a needle sheath 400 are also provided. The liquid storage device 100 is used to accommodate the inhaled liquid, and the booster device 200 sucks or injects the liquid under the action of external force.

[0052] The liquid storage device 100 is provided with a connection joint 110 and an elastic capsule 120 , the elastic capsule 120 is assembled in the inner cavity of the connection joint 110 , and the elastic capsule 120 is in sealing connection with the inner cavity of the connection joint 110 . Specifically, the inner cavity of the elastic capsule 120 and the connection joint 110 can be sealed and connected by ultrasonic welding or other methods.

[0053] The elastic capsule 120 is provided with a capsule wall 121 and a capsule cavity 122 , the capsule wall 121 is fixedly connected with the capsule cavity 122 , and the ca...

Embodiment 2

[0062] A syringe with a reusable booster device, the other structure is the same as that of Embodiment 1, the difference is that: the capsule wall 121 and the capsule cavity 122 are integrally formed, which has the characteristics of convenient processing, low cost and good sealing effect.

Embodiment 3

[0064] A syringe with a reusable booster device, other structures are the same as those in Embodiment 1 or 2, the difference is that it also has the following technical features: such as figure 2 , image 3 , Figure 4 As shown, the booster device 200 is also provided with a one-way locking mechanism, and the one-way locking mechanism is provided with a mounting seat 231 , an injection buckle 232 and an elastic member 233 .

[0065] The mounting seat 231 is fixedly disposed on the outer wall of the open end 212 of the jacket 210 , and the injection buckle 232 is movably disposed on the mounting seat 231 . Specifically, the injection buckle 232 is movably assembled to the mounting seat 231 through a shaft. It should be noted that the injection buckle 232 can be assembled on the mounting base 231 in different ways, not limited to the way in this embodiment.

[0066] The injection buckle 232 is provided with a buckle end 2321 for snapping and assembling the core rod 220. The ...

Abstract

A syringe capable of repeatedly using a drive device, and a liquid storage device (100) thereof. The syringe is provided with a liquid storage device (100) and a drive device (200); the liquid storage device (100) is provided with a connection joint (110) and an elastic medicine bladder (120), the elastic medicine bladder (120) is disposed in an inner cavity of he connection joint (110), and the elastic medicine bladder (120) is connected to the inner cavity of the connection joint (110) in a sealing manner; the drive device (200) is provided with a jacket (210) and a core bar (220), one end of the core bar (220) is provided with a rubber plug (221), the core bar (220) is disposed inside of the jacket (210) and the rubber plug (221) contacts the inner wall surface of the jacket (210) in a sealing manner, and the connection joint (110) is disposed at an assembly end (211) of the jacket (200); and the elastic medicine bladder (120) is provided with a bladder wall (121) and a bladder cavity (122). The drive device (200) is further provided with a unidirectional fastening structure, and the unidirectional fastening structure is provided with a mounting base (231), an injection clip (232), and an elastic part (233); the core bar (220) is further provided with a clipping position (222), a clip end (2321) is fastened to the clipping position (222). The syringe can repeatedly use the drive device, so that the money spent by the patients is saved and the raw materials are greatly conserved, thereby conforming to the environmental requirements.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a syringe with a reusable booster device and a liquid storage device thereof. Background technique [0002] Syringes are one of the commonly used medical supplies for intravenous injection in the medical field. In the prior art, the syringe is usually composed of main components such as a casing, a core rod assembled inside the casing, and an injection needle. When the liquid is sucked, the core rod is pulled, and the negative pressure generated sucks the liquid into the inner cavity of the jacket. When injecting, the core rod is reversely pushed to push the liquid out of the inner cavity of the jacket through the injection needle for injection. [0003] The syringe in the prior art, once used, its jacket, core rod and injection needle will all be discarded, which cannot realize the reuse of the syringe or some components constituting the syringe. Not only the use cost ...
