Description

Technical Field

[0001] This utility model relates to the technical field of antibacterial syringe auxiliary devices, and in particular to an antibacterial syringe. Background Technology

[0002] The prototype of the syringe can be traced back to the 17th century, invented by the English physician Christopher Wren. However, the design at that time was rudimentary and mainly used for injecting drugs into animals. With the development of medicine, the design of syringes gradually improved. In 1853, a French physician combined a silver tube with a hollow needle, inventing a tool similar to the modern syringe. In medical practice, syringes are used extensively and frequently; therefore, the development of syringes with antibacterial properties has become an urgent need.

[0003] The lack of antibacterial auxiliary devices on existing disposable syringes poses a risk of bacterial contamination during actual use. Therefore, it is particularly important to design an antibacterial syringe to solve the above-mentioned technical problem. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing disposable syringes do not have antibacterial auxiliary devices, which leads to the risk of bacterial contamination during actual use. Therefore, an antibacterial syringe is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an antibacterial syringe, comprising a tube body, an interface tube at the left end of the tube body, a needle tube movably connected to the interface tube, an injection head slidably disposed in the tube body, a push rod fixedly connected to the right end of the injection head, a protective block fixedly connected to the right end of the tube body, the push rod slidably disposed in the protective block, an antibacterial diaphragm installed on the inner wall of the interface tube near the port position, the antibacterial diaphragm being made of an easily puncturable thin film material, and a puncture end block fixedly connected to the inner wall of the needle tube, the puncture end block having a conical cross-section.

[0006] Preferably, a hand-held block is fixedly connected to the right end of the push rod, and a finger ring is fixedly connected to the hand-held block.

[0007] Preferably, a hand-held block is fixedly connected to the right end of the push rod, and a finger ring is fixedly connected to the hand-held block.

[0008] Preferably, the injection head has grooves evenly distributed in the circumferential direction.

[0009] Preferably, an antibacterial layer is fixed on the inner wall of the protective block.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, during use, an antibacterial diaphragm structure is set at the interface tube position on the left end of the tube body, forming a physical barrier to relatively block bacteria at the port position of the tube body. At the same time, a piercing end block structure is set on the inner wall of the needle tube. When the needle tube is installed in the interface tube, the piercing end block pierces the antibacterial diaphragm, making the needle tube connected to the inside of the tube body. Compared with conventional disposable syringes without antibacterial auxiliary devices, the technical solution adopted by this utility model can achieve relative antibacterial treatment of the syringe, ensuring that the syringe is injected in a relatively clean environment. The antibacterial auxiliary device is directly installed on the syringe, optimizing the space layout and making it easy for staff to install and maintain. It solves the problem that existing disposable syringes without antibacterial auxiliary devices are at risk of bacterial contamination during actual use.

[0012] 2. In this utility model, during use, the injection head has grooves evenly distributed around its circumference, which makes it easier for the injection head to slide in the tube and reduces resistance. The left end structure of the injection head fits into the left inner wall structure of the tube, improving the efficiency of liquid flowing out of the tube. Attached Figure Description

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] This utility model provides an antibacterial syringe, including a tube body 1, an interface tube 101 at the left end of the tube body 1, a needle tube 102 movably connected to the interface tube 101, an injection head 2 slidably disposed in the tube body 1, a push rod 3 fixedly connected to the right end of the injection head 2, a protective block 4 fixedly connected to the right end of the tube body 1, an antibacterial layer 401 fixedly fixed on the inner wall of the protective block 4, the push rod 3 slidably disposed in the protective block 4, an antibacterial diaphragm 103 installed on the inner wall of the interface tube 101 near the port, the antibacterial diaphragm 103 being made of an easily puncturable thin film material, a puncture end block 6 fixedly connected to the inner wall of the needle tube 102, the puncture end block 6 having a conical cross-section, a handheld block 5 fixedly connected to the right end of the push rod 3, and a finger ring 501 fixedly connected to the handheld block 5 for easy holding by the injector;

[0019] In actual use, the antibacterial syringe is installed at the interface tube 101. A puncture block structure is fixedly connected to the inner wall of the syringe 102. When the syringe 102 is fully installed in the interface tube 101, the puncture block punctures the antibacterial diaphragm 103 on the inner wall of the interface tube 101. Then, the operator holds the holding block 5 and uses the finger ring 501 to push and pull the plunger 3 to assist the injection head 2 in sliding inside the tube body 1, thereby injecting the liquid inside the tube body 1. At the same time, a protective block 4 is also installed on the tube body 1 in conjunction with the antibacterial layer 401, so that when the plunger 3 slides in the protective block 4, bacteria can be effectively blocked, ensuring that the injection is carried out in a relatively clean and hygienic environment. The injection head 2 has grooves 7 evenly distributed around its circumference, which allows the injection head 2 to slide in the tube body. During sliding, the device facilitates movement and reduces resistance. By setting an antibacterial diaphragm 103 structure at the interface tube 101 position at the left end of the tube body 1, a physical barrier against bacteria is formed at the port position of the tube body 1. At the same time, a piercing end block 6 structure is set on the inner wall of the needle tube 102. When the needle tube 102 is installed in the interface tube 101, the piercing end block 6 pierces the antibacterial diaphragm 103, so that the needle tube 102 is connected to the inside of the tube body 1. Compared with conventional disposable syringes without antibacterial auxiliary devices, the technical solution adopted by this utility model can achieve relative antibacterial treatment of the syringe, ensuring that the syringe is injected in a relatively clean environment. The antibacterial auxiliary device is directly installed on the syringe, optimizing the spatial layout and making it easy for staff to install and maintain.

[0020] like Figure 1-2 As shown, the left end of the injection head 2 has an arc-shaped structure, and the inner wall of the tube body 1 on the side away from the injection head 2 has an arc-shaped design that fits into the left end of the injection head 2. The injection head 2 has grooves 7 evenly distributed around its circumference.

[0021] The effect achieved by the entire embodiment 1 is that, during use, the injection head 2 has grooves 7 evenly distributed in the circumferential direction, which makes it easier for the injection head 2 to slide in the tube 1 and reduce resistance. The left end structure of the injection head 2 fits into the left inner wall structure of the tube 1, improving the efficiency of liquid flowing out of the tube 1.

[0022] Working principle: The syringe is installed at the interface tube position. A puncture block structure is fixedly connected to the inner wall of the syringe. When the syringe is fully installed in the interface tube, the puncture block punctures the antibacterial diaphragm on the inner wall of the interface tube. Then, the operator holds the holding block and uses a finger ring to push and pull the plunger to assist the injection head in sliding inside the tube, thereby injecting the liquid inside the tube. At the same time, a protective block and antibacterial layer are also installed on the tube, so that bacteria can be effectively blocked when the plunger slides in the protective block, ensuring that the injection is carried out in a relatively clean and hygienic environment. The injection head has grooves evenly distributed around its circumference, which makes the injection head easier to move in the tube and reduces resistance.
