Description

Technical Field

[0001] The invention relates to the technical field of syringes, and in particular to an integrated rabies vaccine syringe for rabies. Background Art

[0002] Rabies is an acute infectious disease caused by the rabies virus and is a zoonosis. As the pathogen of the disease, the rabies virus is mainly transmitted to humans through animal bites. Once the wound is touched by an animal carrying the virus, the virus can quickly invade the human body. The mortality rate of rabies is nearly 100%, and there is currently no effective treatment, so it poses an extremely serious threat to life. Once infected with the rabies virus, the virus will rapidly invade the central nervous system, causing critical illnesses such as encephalitis and myelitis, and ultimately leading to respiratory and circulatory system failure, resulting in the patient's death.

[0003] Given the severity of rabies, prevention is particularly important. Once bitten or scratched by an animal, the wound should be properly treated immediately and rabies vaccination should be given to the hospital as soon as possible to prevent the disease. At the same time, strengthening animal management and promoting vaccination are also key measures to prevent rabies.

[0004] However, in current medical practice, most syringes used to inject rabies vaccines are universal, which means that a lot of time is needed to take, dispense, and extract the medicine during the injection process. In addition, the needle cap of universal syringes is often tightly connected to the needle, which can easily cause injuries to medical staff when removing the needle cap. If the needle cap is adjusted too loose, there is a risk of it falling off. These problems undoubtedly increase the difficulty and danger of medical operations. Summary of the invention

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides an integrated rabies vaccine syringe for rabies.

[0006] The technical solution is: an integrated rabies vaccine syringe for rabies, including a syringe, a rotating cylinder, a piston a, a piston rod, an injection tube, a sealing plug, a needle and a needle cap. The syringe is a cylinder with an opening on the left side, the front side of the syringe is rotatably connected to the rotating cylinder, the rear side of the syringe is slidably provided with a piston a, the rear side of the piston a is fixedly connected to the piston rod, the piston rod passes through the rear part of the syringe, the rear side of the syringe top is provided with an injection tube, the injection tube is threadedly connected with a sealing plug, the front side of the rotating cylinder is connected to the needle, the needle cap is sleeved, and also includes a sealing component and a limiting component. The syringe and the rotating cylinder are jointly provided with a sealing component, the sealing component is used to close the left opening of the syringe, and a limiting component is jointly provided between the rotating cylinder and the needle cap, and the limiting component is used to fix the needle cap to the rotating cylinder.

[0007] Furthermore, the sealed component includes a stud and a piston b. The stud is fixedly connected to the middle of the inner wall of the front side panel of the rotating cylinder. The piston b is threadedly connected to the stud. The side wall of the piston b fits the inner wall of the syringe and can slide on the inner wall of the syringe. Notches are symmetrically opened on the upper and lower sides of the rear side of the piston b.

[0008] Furthermore, the limiting assembly includes a clamping seat, an elastic plate and a trapezoidal clamping block. The clamping seat is symmetrically fixedly connected to the outer wall on the rear side of the needle cap, and two elastic plates are symmetrically fixedly connected to the front side of the rotating cylinder. Both elastic plates are fixedly connected to the adjacent clamping seats with trapezoidal clamping blocks.

[0009] Furthermore, it also includes a sliding ring, a limit plate, a socket and an insertion rod. A sliding ring is slidably connected to the outer wall on the front side of the syringe, a limit plate is fixedly connected to the front side of the top of the syringe, the limit plate passes through the sliding ring, and two sockets are fixedly connected to the left and right sides of the front of the rotating cylinder in an interval manner. Two insertion rods are fixedly connected to the upper side of the sliding ring corresponding to the two sockets, and the two insertion rods can be respectively inserted into adjacent sockets.

[0010] Furthermore, it also includes a limiting frame and a triangular limiting block. The lower side of the sliding ring is fixedly connected to the limiting frame, and the facing side walls of the two elastic plates are fixedly connected with triangular limiting blocks. The limiting frame fits with the front sides of the two triangular limiting blocks.

[0011] Furthermore, it also includes a protective shell, a semiconductor cooling sheet and a battery compartment. The protective shell is fixedly connected to the middle of the outer wall of the syringe, the semiconductor cooling sheet is embedded on the inner wall of the protective shell, and the battery compartment is fixedly connected to the top of the protective shell.

[0012] Furthermore, a support plate is included, and the bottom of the protective shell is fixedly connected with the support plate symmetrically.

[0013] Furthermore, the syringe and the rotating cylinder are both made of transparent material.

[0014] Compared with the prior art, the present invention has the following advantages: 1. The cooperation of piston a, piston b and the sealing plug ensures that the drug solution is isolated from the air, realizing integrated storage of the drug solution and reducing the preparation time before injection. During injection, by rotating the rotating cylinder and moving the piston, the drug solution is smoothly transferred and the air is removed, ensuring the safety of injection. When not in use, the needle cap is firmly fixed to the rotating cylinder by a trapezoidal block to prevent the needle cap from falling off and the needle from being contaminated, thereby protecting medical staff from being injured by the needle and improving the practicality and safety of the syringe.

[0015] 2. By setting the sliding ring and the insert rod, etc., the rotating cylinder can be effectively prevented from rotating accidentally, ensuring the sealing of the syringe. At the same time, the limit frame and the triangular limit block are optimized to automatically open the elastic plate, simplify the operation steps, save time and effort, and improve the convenience and efficiency of the syringe.

DETAILED DESCRIPTION

[0025] The present invention will now be described more fully below with reference to the accompanying drawings, in which currently preferred embodiments of the present invention are shown. However, the present invention may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.

[0026] It should be noted that the words indicating directions such as up, down, left, and right mentioned in this article refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to the parts in this article, such as first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning. The words such as connection and coupling in this application include direct and indirect connection (coupling) unless otherwise specified.

[0027] Embodiment: A rabies vaccine integrated syringe for rabies, such as Figure 1-Figure 8 As shown, it includes a syringe 1, a rotating cylinder 2, a piston a21, a piston rod 22, an injection tube 23, a sealing plug 24, a needle 25 and a needle cap 26. The syringe 1 is a cylinder with an opening on the left side. The front side of the syringe 1 is rotatably connected to the rotating cylinder 2. The piston a21 is slidably arranged on the rear side of the syringe 1. The piston rod 22 is welded and fixed to the rear side of the piston a21. The piston rod 22 passes through the rear part of the syringe 1. The injection tube 23 is welded and fixed to the rear side of the top of the syringe 1. The injection tube 23 is connected to the syringe 1. The internal space of the syringe 1 is connected, the sealing plug 24 is threadedly connected to the injection tube 23, the needle 25 is connected to the front side of the rotating cylinder 2, the needle cap 26 is sleeved on the needle 25, and also includes a sealing component and a limiting component. The syringe 1 and the rotating cylinder 2 are jointly provided with a sealing component, and the sealing component is used to close the left opening of the syringe 1. A limiting component is jointly provided between the rotating cylinder 2 and the needle cap 26, and the limiting component is used to fix the needle cap 26 to the rotating cylinder 2.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, the sealed component includes a stud 31 and a piston b32. The stud 31 is welded and fixed in the middle of the inner wall of the front panel of the rotating cylinder 2. The piston b32 is threadedly connected to the stud 31. The side wall of the piston b32 fits the inner wall of the syringe 1 and can slide on the inner wall of the syringe 1. The rear side of the piston b32 is symmetrically provided with notches 33.

[0029] like Figure 5 As shown, the limiting assembly includes a clamping seat 41, an elastic plate 42 and a trapezoidal clamping block 43. The clamping seat 41 is symmetrically welded and fixed on the outer wall of the rear side of the needle cap 26, and two elastic plates 42 are symmetrically welded and fixed on the front side of the rotating cylinder 2. The two elastic plates 42 are correspondingly welded and fixed with the trapezoidal clamping block 43 to the adjacent clamping seat 41. There is only a small friction force between the needle cap 26 and the needle head 25, so that the needle cap 26 can be easily removed from the needle head 25, and the trapezoidal clamping block 43 can be inserted into the adjacent clamping seat 41, thereby fixing the needle cap 26.

[0030] In the initial state, the piston a21 is located at the rearmost end of the syringe 1. The staff first unscrews the sealing plug 24 and then injects the medicine into the syringe 1 through the injection tube 23. As the medicine is injected, the air inside the syringe 1 will be completely discharged from the injection tube 23. After that, the staff tightens the sealing plug 24 on the injection tube 23 again. In this way, the piston a21, the piston b32 and the sealing plug 24 jointly seal the syringe 1 to ensure that the medicine in the syringe 1 does not contact with the air, thereby achieving a better storage effect. When it is necessary to inject the medicine into the patient, the staff first moves the two elastic plates 42 to separate the two trapezoidal blocks 43 from the adjacent card seats 41 respectively. At this time, the staff can easily remove the needle cap 26. Then, the staff holds the syringe 1 and rotates the rotating cylinder 2. Since the stud 31 is fixedly connected to the rotating cylinder 2, the stud 31 will rotate with the rotating cylinder 2. Under the restriction of the inner wall, the stud 31 can only drive the piston b32 to slide forward, so that the notch 33 opened on the piston b32 is connected with the internal space of the rotating cylinder 2. At this time, the staff stands up the syringe, makes the needle 25 face upward, and pushes the piston rod 22. The piston a21 slides with the piston rod 22, thereby pressing the medicine in the syringe 1 into the rotating cylinder 2. As the medicine is continuously injected, the medicine finally enters the needle 25. When the staff observes that When liquid medicine flows out of the needle 25, it means that the air in the rotating cylinder 2 has been exhausted. At this time, the patient can be injected with liquid medicine. When not in use, the needle cap 26 is firmly restricted on the rotating cylinder 2 through the cooperation of the two trapezoidal blocks 43 and the clamping seat 41, thereby preventing the needle cap 26 from falling off when the syringe is moved, ensuring that the needle 25 will not be contaminated by the external environment, and also preventing the needle 25 from causing damage to the hands of medical staff when the staff forcibly pulls off the needle cap 26.

[0031] like Figure 5 As shown, it also includes a sliding ring 51, a limiting plate 52, a socket 53 and an insertion rod 54. The sliding ring 51 is slidably connected to the outer wall on the front side of the syringe 1, and the limiting plate 52 is fused and fixed to the front side of the top of the syringe 1. The limiting plate 52 passes through the sliding ring 51 to limit the limiting ring 51 so that it cannot rotate. Two sockets 53 are fused and fixed at intervals on the left and right sides of the front of the rotating cylinder 2. Two insertion rods 54 are fixedly connected to the upper side of the sliding ring 51 corresponding to the two sockets 53. The two insertion rods 54 can be respectively inserted into adjacent sockets 53.

[0032] By setting the sliding ring 51, etc., the sliding ring 51 is initially located in a position that fits the rotating cylinder 2, and the two insertion rods 54 are respectively inserted into the adjacent sockets 53, thereby limiting the rotation of the rotating cylinder 2 and preventing the piston b32 from opening accidentally. When the syringe needs to be used, the sliding ring 51 only needs to be slid backward to disengage the insertion rod 54 from the socket 53, thereby releasing the restriction on the rotating cylinder 2.

[0033] like Figure 6 and Figure 7 As shown, it also includes a limiting frame 61 and a triangular limiting block 62. The limiting frame 61 is welded and fixed on the lower side of the sliding ring 51, and the triangular limiting blocks 62 are welded and fixed on the opposite side walls of the two elastic plates 42. The limiting frame 61 is in contact with the front sides of the two triangular limiting blocks 62.

[0034] By setting the limit frame 61 and the triangular limit block 62, when the staff slides the sliding ring 51 backward, the limit frame 61 moves backward with the sliding ring 51 and contacts the inclined surface of the triangular limit block 62, which will push the two elastic plates 42 away from each other, thereby separating the trapezoidal block 43 from the clamping seat 41. In this way, the staff does not need to manually push the two elastic plates 42 apart, which saves time and effort.

[0035] like Figure 1 and Figure 8 As shown, it also includes a protective shell 71, a semiconductor cooling sheet 72 and a battery compartment 73. The protective shell 71 is fixedly connected to the middle of the outer wall of the syringe 1, the semiconductor cooling sheet 72 is embedded on the inner wall of the protective shell 71, and the battery compartment 73 is fixedly connected to the top of the protective shell 71.

[0036] When the syringe is stored, the battery in the battery compartment 73 continuously supplies power to the semiconductor refrigeration chip 72, so that the semiconductor refrigeration chip 72 continues to cool, and the liquid medicine in the syringe 1 is refrigerated, thereby further improving the storage effect of the liquid medicine.

[0037] like Figure 8 As shown, a support plate 8 is also included, and the support plate 8 is fixedly connected to the bottom of the protective shell 71 in a left-right symmetrical manner.

[0038] By providing the support plates 8, when the syringe is placed on a table, the two support plates 8 can provide a stable support function to prevent the syringe from rolling.

[0039] The syringe 1 and the rotating cylinder 2 are both made of transparent material, so it is convenient to observe the liquid medicine in the syringe 1 and the rotating cylinder 2 .
