Description

Technical Field

[0001] This utility model relates to the field of syringe technology, and more specifically, to a syringe disassembly and assembly assembly and a syringe. Background Technology

[0002] Currently, existing syringes draw venom by covering the wound with a nipple and pulling the piston rod to draw the venom from the wound into the syringe. However, wounds vary in size, and the nipple diameter is small, making it unsuitable for different wounds and limiting its practicality.

[0003] Therefore, we have made improvements to this by proposing a syringe disassembly and assembly assembly and a syringe. Summary of the Invention

[0004] The purpose of this invention is to address the issue that existing syringes use a nipple to cover the wound when drawing venom, and then pull the piston rod to draw the venom from the wound into the syringe. However, wounds vary in size, and the nipple diameter is small, making it unsuitable for different wounds and thus impractical.

[0005] To achieve the above-mentioned objectives, this invention provides a syringe disassembly and assembly assembly and a syringe to improve the aforementioned problems.

[0006] The application is as follows:

[0007] A syringe assembly includes a syringe body, a suction section at the top of the syringe body, the suction section being composed of a connecting tube and a nipple, and a disassembly section between the connecting tube and the syringe body for fixing the connecting tube and the syringe body.

[0008] As a preferred technical solution of this application, the bottom end of the nipple is fixedly connected to the middle part of the top end of the connecting cylinder, and the inside of the nipple is connected to the inside of the connecting cylinder, and the bottom end of the connecting cylinder is open.

[0009] As a preferred technical solution of this application, the disassembly part is a rubber layer, the bottom end of the connecting cylinder is provided with an internal thread groove, the top end of the outer side of the syringe body is provided with an external thread groove that matches the internal thread groove, the bottom end of the rubber layer is fixedly connected to the top end of the syringe body, and the top end of the rubber layer is in contact with the top end of the internal thread groove.

[0010] A syringe includes a piston disposed within a cavity formed by a syringe body and a connecting tube. A piston rod is fixedly disposed at the bottom end of the piston, and a limiting mechanism is provided between the piston rod and the syringe body.

[0011] As a preferred technical solution of this application, the limiting mechanism is composed of a first limiting part and a second limiting part.

[0012] As a preferred technical solution of this application, the first limiting part is composed of two limiting blocks and two limiting members.

[0013] As a preferred technical solution of this application, one side of each of the two limiting blocks is fixedly connected to the bottom ends of both sides of the syringe body, and an L-shaped groove is opened in the other side of the limiting block. One side of the limiting member is fixedly installed at one end of the L-shaped groove.

[0014] As a preferred technical solution of this application, the second limiting part is composed of two sliding rods. One side of each sliding rod is fixedly connected to both sides of the piston rod. The other end of each sliding rod is inserted into the L-shaped groove. A plurality of limiting grooves matching the limiting member are equidistantly provided on the other side of the sliding rod.

[0015] As a preferred technical solution of this application, the sealing part includes a sealing cap, and the syringe body is provided with a scale.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In the scheme of this application:

[0018] 1. To address the problem that existing syringes, when drawing venom, use a nipple to cover the wound and pull the piston rod to draw the venom into the syringe, but wounds vary in size and the nipple diameter is small, making them unsuitable for different wounds and resulting in low practicality, this application proposes a disassembly / removal part. The internal and external threaded grooves of the disassembly / removal part allow the syringe body to be fixed to the suction part. The nipple of the suction part can be used to draw venom from small wounds, and by removing the suction part, the syringe body, in conjunction with the rubber layer of the disassembly / removal part, can draw venom from large wounds. This design makes it suitable for wounds of different sizes, improving practicality.

[0019] 2. With the setting of the limiting mechanism, as the piston rod moves, the limiting mechanism can be driven to operate. Under the action of the limiting mechanism, the piston rod after it has moved can be fixed, which prevents the piston rod from being sucked back and affecting the absorption of venom, thus improving practicality.

The internal threaded groove 302 and the external threaded groove 303 allow for a fixed connection between the connecting cylinder 201 and the syringe body 1.

[0044] Example 2

[0045] The syringe assembly / disassembly component provided in Example 1 has been further optimized, specifically, as follows: Figures 1-4 As shown, a syringe includes a piston 4, which is disposed in a cavity formed by a syringe body 1 and a connecting tube 201. A piston rod 5 is fixedly provided at the bottom end of the piston 4, and a limit mechanism 6 is provided between the piston rod 5 and the syringe body 1.

[0046] Furthermore, such asFigure 3 As shown, the limiting mechanism 6 consists of a first limiting part and a second limiting part.

[0047] Example 3

[0048] The syringe provided in Example 1 or 2 is further optimized, specifically, as follows: Figures 3-4 As shown, the first limiting part consists of two limiting blocks 601 and two limiting members 602.

[0049] Furthermore, such as Figures 3-4 As shown, one side of each of the two limiting blocks 601 is fixedly connected to the bottom of the two sides inside the syringe body 1. An L-shaped groove is opened in the other side of the limiting block 601. One side of the limiting member 602 is fixedly installed at one end of the L-shaped groove. The limiting member 602 is made of a material with a certain degree of toughness.

[0050] Furthermore, such as Figures 3-4 As shown, the second limiting part consists of two slide rods 603. One side of each slide rod 603 is fixedly connected to both sides of the piston rod 5. The slide rod 603 is inserted into the other end of the L-shaped groove. Several limiting grooves matching the limiting member 602 are equidistantly opened on the other side of the slide rod 603.

[0053] The following is the usage process of the syringe disassembly and assembly assembly and the syringe provided by this utility model:

[0054] When treating small wounds, the nipple 202 is placed over the wound, and the piston rod 5 is pulled. The piston rod 5 moves the piston 4, which draws in the venom from the wound. At the same time, the piston rod 5 moves the slide rod 603, which lifts the limiting member 602. The slide rod 603 continues to move, and the limiting member 602 springs back into the next limiting groove. Under the action of the limiting groove, the limiting member 602 is held in place, preventing the piston rod 5 from being sucked back. In this way, the piston rod 5 can be fixed after it has moved, preventing it from being sucked back. When treating large wounds, the connecting cylinder 201 can be removed from the syringe body 1 through the internal thread groove 302 and the external thread groove 303. The end of the syringe body 1 with the rubber layer 301 is placed over the large wound, and the piston rod 5 is pulled to draw in the venom.
